This specification relates to a fixing system for cladding. In particular, although not exclusively, the fixing system may be utilised to secure weatherboards to the walls or framing of buildings. The fixing system also has applications in relation to fencing, screens, and roofing.
BACKGROUND TO THE INVENTIONThere are numerous weatherboard designs on the market. The most important feature of a weatherboard design is its cross-sectional profile. This profile dictates the way in which the weatherboards should be installed and the overall appearance of the weatherboard cladding after installation. Commonly, weatherboards are designed to be installed in an overlapping relationship with each other and can be fixed horizontally, vertically or on an angle. Further, some weatherboard designs include grooves that, when installed, cooperate with the grooves of overlapping like weatherboards to provide anti-capillary channels. Such channels prevent moisture from getting in behind the weatherboards and causing damage.
During installation, the weatherboards shown in

In this specification where reference has been made to patent specifications, other external documents, or other sources of information, this is generally for the purpose of providing a context for discussing the features of the inventions. Unless specifically stated otherwise, reference to such external documents is not to be construed as an admission that such documents, or such sources of information, in any jurisdiction, are prior art, or form part of the common general knowledge in the art.
It is an object of the present invention to provide an improved fixing system for cladding and an associated cladded structure, or to at least provide the public with a useful choice.
SUMMARY OF THE INVENTIONIn a first aspect, the present invention broadly consists in a fixing strip for holding cladding boards up against framing, the strip being securable to the framing and being arranged to, in co-operation with a number of like strips, receive and retain boards thereon, each board having front and rear faces and being arranged to be fixed to the framing in a partially overlapping relationship relative to one another, a recess being provided in and along the rear face of each board, the fixing strip being an elongate strip of material defined by a front face and a rear face extending between a top end and bottom end and comprising a series of integral fixing clips spaced apart along the length of the strip that form rows of fixing clips when a number of strips are secured to the framing, each fixing clip comprising an engagement tab that is a substantially flat portion of material punched from the strip and which is adjoined to the strip at an intact edge of the tab, the engagement tab being bent about a bending edge so as to extend at an acute angle relative to the front face of the strip for engaging in the complementary recess of a cladding board in a holding relationship to enable the boards to be held on the framing by the fixing clips.
Additionally, each fixing clip may further comprise an alignment (or ‘secondary’) tab situated below its associated engagement tab relative to the top end of the strip. Preferably, the alignment tab is a substantially flat portion of material punched from the strip and which is adjoined to the strip at an intact bending edge of the tab, the alignment tab being bent about the bending edge so as to extend at a predetermined angle relative to the front face of the strip.
Preferably, the engagement tab is substantially rectangular in shape and is defined by left and right parallel edges extending from its lateral intact edge at the front face of the strip and terminating at an upper lateral edge displaced from the front face of the strip. The left and right edges, and the upper lateral edge, are free edges in the sense that they are no longer directly connected to the strip of material.
In one form, the intact edge of the engagement tab may be aligned with the bending edge or line. In another form, the bending edge of the engagement tab may be located below the intact edge such that the punching of the tab displaces the intact edge from the front face of the strip to thereby form integral reinforcement webs or gussets on each left and right side of the tab, each web extending outwardly the front face of the strip toward its respective left or right side of the tab in the region between the intact edge and bending edge. In one form, each left and right web is substantially triangular in shape.
Preferably, the alignment tab is substantially rectangular in shape and is defined by left and right parallel edges extending from its lateral bending edge at the front face of the strip and terminating at an upper lateral edge displaced from the front face of the strip. The left and right edges, and the upper lateral edge, are free edges in the sense that they are no longer connected to the strip of material.
In one form, one or both of the engagement and alignment tabs of each fixing clip have a larger width (transverse to the longitudinal direction of the strip) than their length. In another form, the alignment tab has a larger length than its width.
Preferably, one or both of the engagement and alignment tabs of each fixing clip are centrally located relative to the width of the strip (in the direction transverse or perpendicular to its longitudinal direction).
Preferably, the engagement tab has a larger surface area than its associated alignment tab.
Preferably, the bending edges of one or both of the engagement and alignment tabs extend substantially perpendicular to the longitudinal direction of the strip.
Preferably, the fixing clips are equi-spaced along the length of the fixing strip.
Preferably, the alignment tab is bent away from the front face of the strip at a greater angle relative to the angle at which the engagement tab is bent from the front face of the strip.
Preferably, the engagement tab is bent away from the front face of the strip about its bending edge at a predetermined acute angle. Preferably, the acute angle is in the range of about 30° to about 60°.
Preferably, the alignment tab is bent away from the front face of the strip about its bending edge at a predetermined angle. In one form, the alignment tab is bent to an angle that is substantially perpendicular to the front face of the strip, but other angles could alternatively be employed.
Preferably, the strip is formed from a substantially rigid material, or material at least having substantial thickness to be substantially rigid. By way of example, the material may be any of the following: metal, steel, aluminium or any other appropriate material that is capable of achieving a nominated holding power for retaining the cladding boards on the framing. In a preferred form, the material may have at least a 50-year durability, although this is not essential.
In one form, the fixing strip is substantially planar or flat (apart from in the region of the integral fixing clips). For example, the rear face of the fixing strip is substantially planar or flat, as is the front face apart from the protruding fixing clips. In one embodiment, the cross-section through the fixing strip in an area not containing a fixing clip is substantially flat.
In one form, the bending edges of the engagement and alignment tabs of each fixing clip may be located at a common position. In another form, for each fixing clip, the bending edge of the alignment tab is located below the bending edge of the engagement tab.
In one form, for each fixing clip, the alignment tab is at least partially formed from the same portion of material of the strip that forms the engagement tab. In another form, for each fixing clip, the alignment tab is entirely formed from the same portion of material of the strip that forms the engagement tab. In another form, for each fixing clip, the portions of strip material forming the engagement tab and alignment tab do not overlap.
In one form, the upper lateral edge of the engagement tab is displaced further from the front face of the strip than the upper lateral edge of the alignment tab.
Preferably, one or more mounting apertures are provided extending through the fixing strip. In one form, one or more mounting apertures are provided between each spaced-apart fixing clip. The mounting apertures may be any desired shape or size, and may be located at any desired position relative to each fixing clip. Any combination, placement or pattern of the same mounting apertures or a mixture of different sizes and shapes of mounting apertures may be provided along the length of the fixing strip.
In use, an end region or portion of the engagement tab of each fixing clip forms an engagement surface that abuts against a complementary inclined surface of the recess in the rear face of the board such that the board rests on the engagement tab against gravity in an abutting relationship.
In use, the alignment tab of each fixing clip provides an engagement surface that is arranged to temporarily contact a section of the upper surface of a cladding board to be installed on the lower adjacent row of fixing clips during installation. For example, the alignment tabs of the row of fixing clips above the row of fixing clips onto which a cladding board is to be installed act as an alignment or stop into which the board may be slid into and then dropped down for installation onto the lower row of fixing clips.
In use, the alignment tab of each fixing clip may also act as a retaining or engagement tab for cladding boards installed on the lower adjacent row of fixing clips. For example, in use, each (i.e. all of) or at least some of the alignment tabs of the fixing clips for a row of cladding boards may be bent downward about their respective lateral bending edge from their original alignment position into abutting contact or engagement with a section of the upper surface of a cladding board installed on the lower adjacent row of fixing clips. In this way, each board is supported and held on the framing by the engagement tabs of its corresponding row of fixing clips that engage into the complementary recess in the rear face of the board and additionally by at least one or more of the alignment tabs of the adjacent upper row of fixing clips that are bent down into holding or clamping engagement with respective sections of the upper surface of the board to assist in holding or clamping the board down into engagement with the engagement tabs of its respective row of fixing clips.
In a second aspect, the present invention broadly consists in a fixing strip that is mountable to framing for holding cladding boards up against the framing, the fixing strip comprising an elongate strip of material defined by a front face and a rear face extending between a top end and bottom end and comprising a series of integral fixing clips spaced apart along the length of the strip, each fixing clip comprising an engagement tab that is a flat portion of material formed from the strip and which is adjoined to the strip at an intact edge of the tab, the engagement tab being angled so as to extend at an acute angle relative to the front face of the strip for engaging in the complementary recess of a cladding board in a holding relationship.
Preferably, the engagement tab is angled about a bending line in the strip of material that has a transverse orientation relative to the longitudinal direction of the strip.

Preferably, the fixing clips of the third or fourth aspects of the invention are arranged to be securely attached directly or indirectly to the framing. In one form, one or more mounting apertures are provided in the mounting plate through which fixing components may extend so as to securing the fixing clip to the framing. By way of example, the fixing components may be nails, screws or any other type of fixing component. In an alternative form, the fixing clips may be secured to the framing by adhesive situated between the rear face of the mounting plate and the framing.

In one form, the fixing clip(s) are fixed to a flat surface of the elongate member, but alternatively the elongate member may comprise a flat surface having one or more complimentary recesses within which the fixing clip(s) are received and retained such that the front face of the fixing clip is flush with the remainder of the flat surface of the elongate member.
In a seventh aspect, the present invention broadly consists in a fixing system for securing cladding boards to framing in a partially overlapping relationship, each board having front and rear faces extending between upper and lower surfaces with a recess being provided in and along the rear face, the fixing system comprising:
-
- a plurality of fixing strips of the first or second aspects of the invention or fixing clips of the third or fourth aspects of the invention that are supported by the framing and are spaced apart and aligned on the framing relative to each other so as to provide rows of fixing clips on the framing for supporting rows of boards, each fixing clip having an engagement tab that is arranged to engage with a section of the recess of a board to, in co-operation with a number of other fixing clips of the same row also engaging with a section of the recess, support the board in place on the framing; and
- a plurality of fixing components that are arranged to extend through the front face of each board within the overlapping region of adjacent boards and into the framing to secure each board to the framing in co-operation with the fixing clips.
The fixing strips or fixing clips of the fixing system may have any one or more of the features mentioned in respect of the first-fourth aspects of the invention.

Preferably, the alignment tab of at least some or all of the fixing clips act as retaining or engagement tabs for cladding boards installed on the lower adjacent row of fixing clips. More preferably, each or at least some of the alignment tabs of the fixing clips for a row of cladding boards are bent downward about their respective lateral bending edge or otherwise from their original alignment position into abutting contact or engagement with a section of the upper surface of a cladding board installed on the lower adjacent row of fixing clips. In this way, each board is supported and held on the framing by the engagement clips of its corresponding row of fixing clips that engage into the complementary recess in the rear face of the board and additionally by at least one or more of the alignment tabs of the adjacent upper row of fixing clips that are bent down into holding or clamping engagement with respective sections of the upper surface of the board to retain the board in an engaged state with the engagement tabs of its respective fixing clips.
In an eighth aspect, the present invention broadly consists in a fixing system for securing cladding boards to framing in a partially overlapping relationship, each board having front and rear faces extending between upper and lower surfaces with a recess being provided in and along the rear face, the fixing system comprising:
-
- a plurality of fixing strips of the first or second aspects of the invention or fixing clips of the third or fourth aspects of the invention that are supported by the framing and are spaced apart and aligned on the framing relative to each other so as to provide rows of fixing clips on the framing for supporting rows of boards, and each fixing clip comprising:
- an upper engagement tab that is arranged to engage with a section of the recess of a board to, in co-operation with a number of other fixing clips of the same row also engaging with a section of the recess, support the board in place on the framing.
Optionally, each fixing clip may further comprise a lower (or ‘secondary’) tab in the form of a lower engagement tab situated below the upper engagement tab and which is arranged to be bent into abutting contact or engagement with a section of the upper surface of a cladding board installed on the lower adjacent row of fixing clips to force, clamp or hold the board down into engagement with the engagement tabs of its respective row of fixing clips. Alternatively, the lower tab may be in the form of an alignment tab that is not configured for bending into engagement or contact with the upper surface of a cladding board installed on the lower adjacent row of fixing clips, but rather provides a fixed alignment surface or guide that may temporarily contact a section of the upper surface of a cladding board to be installed on the lower adjacent row of fixing clips during installation. For example, the alignment tabs of the row of fixing clips above the row of fixing clips onto which a cladding board is to be installed act as an alignment or stop into which the board may be slid to indicate clearance for then dropping and/or pivoting the lower portion of the board into engagement with its lower row of fixing clips.

In one form, the fixing strips or individual fixing clips are secured to respective cavity battens which are in turn fixed to the framing. Preferably, the battens being spaced apart and aligned on the framing relative to each other to provide rows of fixing clips on the framing for supporting rows of boards. The battens may be formed from any suitable type of material, such as wood, plastic, metal, steel or any combination thereof. The battens may be any desired length as required.
Preferably, the recess in the rear face of each board includes an inclined upper surface extending in from the rear face of the board and which, in use, is arranged to rest upon the engagement tabs of a row of fixing clips to thereby support the board in place on the framing.
Preferably, each board is provided with grooves along its front and rear faces and is arranged to abut another board in a partially overlapping relationship when installed on the framing such that the grooves of the front and rear faces co-operate to form a channel, the fixing components being arranged to extend through the front face of each board and into the framing within the overlapping region of adjacent boards but under the respective channels to secure each board to the framing in co-operation with the fixing clips.
Preferably, the fixing components are arranged to extend through the front face of each board within the overlapping region and into the framing behind each board such that the fixing components are concealed underneath the overlapping portion of an adjacent board.
Preferably, the fixing components are selected from the following: nails, screws, or staples.
In a ninth aspect, the present invention broadly consists in a method of installing cladding boards onto framing in a partially overlapping relationship such that adjacent boards have an overlapping region, each board having front and rear faces extending between upper and lower surfaces with a recess being provided in and along the rear face, the method comprising the steps of:
-
- (a) securing a plurality of spaced-apart fixing strips of the first or second aspects of the invention or fixing clips of the third or fourth aspects of the invention to the framing such that they are aligned to form rows of fixing clips on the framing, each row of fixing clips being arranged to support a board or row of boards and each fixing clip having an engagement tab that is arranged to engage with a section of the recess of a board to, in co-operation with a number of other fixing clips of the same row also engaging with a section of the recess, support the board in place on the framing, the vertical distance between the rows of fixing devices determining the overlapping region between adjacent boards;
- (b) engaging a first board or first row of boards with the lower-most row of fixing clips such that the engagement tabs of the fixing clips of that row engage into the recess of the rear face of the first board or first row of boards to support and hold the board(s) in place on the framing; and
- (c) repeating step (b) for each next upper adjacent board or rows of boards in relation to their respective rows of fixing clips to progressively clad the framing with boards from the bottom up.
In a first form, the method further comprises the step of driving a number of fixing components through the front face of the first board or row of boards and into the framing along the length of the board(s) within the overlapping region to secure the board(s) in place on the framing after each step (b) and prior to installing the next upper adjacent board or row of boards. By way of example, the fixing components may be selected from, but not limited to, the following: nails, screws, or staples.
As set out above, each fixing clip may have a bendable alignment (or ‘secondary’) tab that features as a lower engagement tab. In a second form, the method further comprises bending or causing each or at least some of the alignment tabs of the next free adjacent row of fixing clips above the last installed row of cladding boards to bend downward into abutting contact or engagement with a section of the upper surface of the last installed board or row of boards so as to hold or clamp the board(s) down into engagement with the engagement tabs of their respective row of fixing clips after each step (b) and prior to installing the next upper adjacent board or row of boards. Optionally, this step may further comprise driving a number of fixing components through the front face of the last installed board or row of boards and into the framing along the length of the board(s) within the overlapping region to secure the board(s) in place on the framing.

The inventions consist in the foregoing and also envisages constructions of which the following gives examples only.
Preferred embodiments of the invention will be described by way of example only and with reference to the drawings, in which:
By way of example, the fixing system of the invention will be described with reference to cladding boards of the weatherboard type. The weatherboards are arranged to be installed on framing or walls of a building in a partially overlapping relationship and are preferably provided with grooves on the front and rear faces that, when installed, co-operate to form an anti-capillary channel in the overlapping region of two adjacent weatherboards. It will be appreciated that there are many different weatherboard or cladding board designs that could provide for the overlapping relationship and the channel, and these alternative designs are all intended to be included within the scope of the invention. Further, the fixing system will work with boards that are not designed to form anti-capillary channels, i.e. boards profiles that do not have anti-capillary grooves.
In general, the invention relates to a concealed fixing system for securing cladding boards to the framing, walls, or other support structure of a building to form an overall cladded structure. The fixing system is entirely concealed when the boards are installed. The fixing system comprises rows of spaced apart fixing clips supported, directly or indirectly, by the framing or wall or other support structure, each row of fixing clips being arranged to support a board or row of boards via engagement into a complementary recess provided in the rear face of each board. As will be explained in more detail, one form of fixing clip comprises a primary or engagement tab for engaging into the recess of the board it is supporting and a secondary or lower alignment tab that assists in alignment of the lower row of boards onto their respective fixing clips.
In one embodiment, the fixing system may additionally utilise a number of fixing components, such as nails, that extend through the front face of each board along an upper edge or region of the board in the overlapping region between adjacent boards and into the framing to secure the boards to the framing, although this is not essential depending on the nature or type of installation.
In an alternative embodiment, the fixing system may additionally or alternatively utilise the alignment tabs of the fixing clips to assist in securing the boards to the framing in that the alignment tab may be bent down into abutting contact or engagement with a section of the upper surface of the cladding board installed on the lower adjacent row of fixing clips during installation. With this configuration, the alignment tabs act to apply downward force on or act as a stop at the upper surface of the boards so as to assist in holding them in an engaged state with the engagement tabs of their respective row of fixing clips, ie the alignment tabs assist in preventing the boards from sliding up and out of engagement with their engagement tabs. In this embodiment, the fixing clips may solely support the boards on the framing, although fixing components, such as nails, extending through the overlapping region as above may also be used to further secure the boards if desired.
First EmbodimentReferring to
Each cavity batten 22 is provided with a number of fixing clips (or clip formations) 30 spaced apart along its length. As will be explained in further detail later, the fixing clips 30 are integrally formed in fixing strips that are attached or fixed to the surface of each cavity batten. In alternative embodiments, the fixing system need not employ cavity battens 22, and in such arrangements the fixing strips of clips 30 may be attached directly to the wall 24, framing 26 or other cladding surface or structure with nails, screws, staples, adhesive, or any other fixing means so as to form the rows of aligned clips 30.
As will be explained in further detail later, the preferred form fixing clips 30 include an engagement tab that is arranged to engage with or into a section of a complementary recess provided in and along the rear face of a board. The cavity battens 22 are arranged such that, when installed, the fixing clips 30 form rows, each row of clips being arranged to engage into the recess in the rear face of a board or row of boards to hold the board or boards in place against the battens and/or framing. There is one row of fixing clips for each row of boards. A number of fixing clips 30 of a row are arranged to co-operate together to engage in sections of the complementary recess of a board to hold the board in place against the wall 24 or framing 26. In use, the engagement tab of each fixing clip 30 acts as a support member or surface upon which a section of the cladding board rests against gravity.
Fixing Clip ConfigurationWith reference to
Each fixing strip 40 extends between a top end 40a and a bottom end 40b and is defined by a front facing surface 42 and a rear facing surface (not visible) on the opposite side. In use, the rear surface is arranged to be fixed to a cavity batten or directly the cladding structure if battens are not used. Each fixing strip is arranged to be installed in a vertical orientation with the top end 40a located above the bottom end 40b relative to the ground. The opposing front surface 42 faces the cladding boards. The fixing clips 30 protrude from the front surface 42 of the strip 40 for engagement with the cladding boards to be installed. In the preferred form, each fixing clip 30 comprises a pair of tabs, namely a primary upper engagement tab 50 and a secondary lower alignment tab 60. In this embodiment, the alignment tab 60 is not necessarily essential but desirable to assist the installation process as will be explained in detail later. Both tabs 50,60 are punched from a portion or portions of material of the strip and bent to protrude from the front surface 42 of the strip by respective predetermined angles. In this first form, both tabs are substantially planar and flat. In the preferred form, the tabs 50,60 are substantially rectangular having a larger width than height (in the elongate direction (L) of the strip). In the preferred form, the tabs are centrally located with respect to the width (W) of the strip transverse to the longitudinal direction of the strip.
The parallel left 52 and right 54 edges of the engagement tab 50, along with its upper lateral edge 56, are uncoupled or detached from the strip from the punching formation, leaving the lower lateral edge 58 (parallel with the upper edge) of the tab 50 intact and still adjoined or coupled with the strip. The lower lateral edge 58 of the engagement tab 50 essentially forms a bending edge from which the remainder of the tab bends or extends outwardly relative to the front face 42 of the strip. In the embodiment shown, the upper left and right corners of the engagement tab 50 are rounded for safety during installation, although this is not essential to their operation. The smaller alignment tab 60 has a similar construction with the parallel left 62 and right 64 edges, and the lateral upper edge 66, being uncoupled from the strip, and leaving the lower later edge 68 coupled to the strip as the bending edge. As shown, the straight bending edges 50 and 60 of both of the tabs 50,60 extend in a direction that is substantially perpendicular or transverse relative to the longitudinal direction of the fixing strip 40. As shown, the left 52,62 and right 54,64 edges, and the upper lateral edge 56,66, are free edges of the tabs 50,60 in the sense that they are no longer connected to the strip of material.
In the preferred form, the engagement tab 50 has a larger surface area than the alignment tab 60 as it is performing a support function. As shown, the upper lateral edge 56 of the engagement tab 50 is displaced a further distance from the front face 42 of the strip 40 than the upper lateral edge 66 of the smaller alignment tab 60. Additionally, the upper lateral edge 56 of the engagement tab 50 extends above (in respect of the longitudinal direction of the fixing strip 40 when installed) the upper lateral edge 66 of the alignment tab 60. For example, the engagement tab 50 terminates at its upper lateral edge 56 at a position that appears closer to the top end 40a of the fixing strip than the upper lateral edge 66 of its alignment tab 60 (from a plan view of the fixing strip).
In the embodiment shown, each alignment tab 60 is at least partially formed or punched from a portion of the material of the strip from which the engagement tab 50 is formed, i.e. the alignment tab 60 is at least partially punched out from the larger engagement tab 50. In the embodiment shown, this partial overlap between the material of the strip forming the tabs 50,60 occurs as the lower lateral edge 68 of the alignment tab 60 is displaced only slightly below the lower lateral edge 58 of the engagement tab 50, such that the strip material forming each tab partially overlaps. It will be appreciated that this arrangement is not necessarily essential. In another embodiment, the lower lateral edges 58,68 of the tabs 50,60 may be aligned such that both tabs extend from a common bending edge and in this case the alignment tab 60 is entirely punched from the strip of material defining the engagement tab 50. In yet another embodiment, the alignment tab 60 may be displaced further below the engagement tab 50 such that there is no overlap in material used to form each tab, i.e. both tabs 50,60 of each fixing clip 30 may be formed from different portions of the strip material, and the portions may be close or immediately adjacent each other.
Once punched from the strip, each of the tabs 50,60 is bent about its bending edge upwardly from the front face 42 of the strip by a predetermined angle, or alternatively the punching process may simultaneously perform the required bending of the tabs. The angles of the tabs relative to the front face will be explained in more detail later, but typically the alignment tab 60 is disposed or bent at a greater angle relative to the front face 42 of the strip than the engagement tab 50. The angles of bending are defined between the front face of the strip and the surfaces of the tabs formed by the rear face of the strip of material once punched out. In one embodiment, the engagement tab 50 is bent at an acute angle relative to the front face 42 of the strip 40 such that it extends outwardly and upwardly toward the top end 40a of the strip, while the alignment tab 60 is bent at a greater angle so as to extend, for example but not limited to, substantially perpendicularly from the front face 42 of the strip 40. The material used to form the strips is preferably of suitable strength, rigidity and/or thickness such that the angle of the tabs 50,60 is substantially fixed once punched and bent to the desired profile angles, or at least the engagement tab 50 is configured or formed to remain fixed in position under load of a board.
As discussed, the fixing system may or may not employ cavity battens. In systems that employ cavity battens 22, one or more fixing strips 40 are secured along the length of each cavity batten with nails, screws, adhesive or any other fixing means, as shown in
In the embodiment shown, each fixing strip 40 is provided with a plurality of mounting apertures 70 between each spaced-apart fixing clip 30. In this form, the mounting apertures are a series of holes centrally located along the length of the strip between each of the fixing strip, although it will be appreciated that this configuration may be varied as desired.
In fixing system systems that do not use cavity battens, each fixing strip 40 is secured directly to the framing 26 via fixing components, such as screws, that extend through the some or all of the mounting apertures and into the framing 26.
Co-Operation of Fixing Clips with Cladding BoardsWith reference to
With reference to
As shown, one side of the engagement tab 50 abuts or contacts the recess to hold the board in place, namely the engagement surface 50a, which is the side of the tab that faces toward the fixing strip 40 (and which is actually formed from a portion of the rear face of the fixing strip after the punching). In this embodiment, only an end region or portion of the engagement surface 50a adjacent the upper edge 56 of the engagement tab abuts with the inclined upper surface 74c of the recess 74 of the board 28a to thereby support the board 28 against gravity, although it will be appreciated the contact region may be larger in other embodiments where a deeper recess 74 is provided in the board. The angular position θE of the engagement tab 50a relative to the front face 42 of the fixing strip 40 may be any acute angle, but may often be between the range of about 30° to about 60°, although this will depend on design requirements. The angle θE of the engagement tab 50 is arranged to complement the angle of the inclined upper surface 74c of the recess 74 of the board when installed such that the abutting relationship acts to both hold the board against the framing and support the board against gravity. It will be appreciated that the angle θE of the engagement tab 50 can be configured to suit any particular cladding board profile, and will depend on the desired profile used and the amount of overlap desired between the boards when installed.
In this embodiment, the purpose of the alignment tab 60 is to provide a guide or stop for alignment and installation of the lower cladding board 28b. For example, the alignment tab 60 serves as an indicator that the board 28b when being installed has reached a position of clearance for engagement with the engagement tabs of its row of fixing clips (not shown in
Therefore the lower board 28b is installed on the framing prior to the upper board 28a (although both are shown installed in
In this position, the engagement tabs 50 of the fixing clips for the lower board 28b may extend into and contact the back surface (equivalent to 74b shown for the upper board 28a) for their respective recess of the rear face of the lower board 28b in a partially installed position, depending on how the board is angled. From this position, the installer drops, slides, and/or pivots the lower portion of the board 28b to cause the engagement tabs to contact the inclined upper surface (equivalent to 74c of the upper board 28a) and come to rest in a fully installed position with the engagement tab in a hook-like engagement relationship with its complementary recess as described above. As shown, the alignment tabs 60 are preferably bent so as to extend from the front face 42 of the strip 40 at an angle θA that is at least greater than its corresponding engagement tab angle θE and in one example corresponds to the flush abutment of the engagement surface 60a with the top or upper surface 80 of the lower board 28b.
As shown in
Installation of cladding boards utilising the fixing system of the inventions will now be described. Firstly, a cavity batten based fixing system will be described with reference to
Typically, the boards 28 are fixed to cavity battens 22 one at a time beginning at the bottom of the framing 26 where the cladding is to start. Typically, the lower-most board is installed first by being engaged against the lower-most row of fixing clips such that the engagement tabs of a number of the fixing clips of that row engage securely in sections of the complementary recess in the rear face of the board in a manner previously described. For longer boards, the boards will be initially engaged centrally onto a centre fixing clip and then additional fixing clips either side of centre of the board, one at a time. For shorter boards, the boards will be engaged onto all fixing clips for that board at once.
With the board 28 held in place against the cavity battens 22 by a number of fixing clips, a number of fixing components 82, such as nails, screws, staples, or the like, can be inserted or driven through the front face and toward the top edge, and preferably under the anti-capillary groove, of the board 28 and into the battens 22 and/or framing 26 to secure the board in place. With the lower-most board in place, the next board may be positioned against the cavity battens such that its rear face recess engages with the engagement tabs of a number of fixing clips of the next row and it may then also be nailed in place. The vertical spacing between the rows of fixing clips is preferably uniform and predetermined to ensure an even overlap of boards up the framing. The overlap also conceals the nails inserted below the anti-capillary channel. Each subsequent board is installed in a similar manner until the cavity battens and/or framing of the building is fully covered.
Installation of the cladding boards utilising the fixing system without cavity battens is similar to the above except that the initial step involves securing a number of fixing strips 40 directly to the framing 26 of the building in a vertical orientation at spaced apart intervals to collectively form the rows of fixing clips 30.
Second EmbodimentReferring to
Referring to
Each fixing clip 130 is similar to the first form previously described except the formation of the engagement tab 150 is different. The substantially rectangular engagement tab 150 is again defined by parallel left 152 and right 154 edges, and an upper lateral edge 156 that are uncoupled or detached from the strip of material from the punching formation, but leaving a lower lateral intact edge 158. In this second form, the engagement tab is bent from the strip of material about a transverse bending edge or line 159 that is situated below and parallel to the intact lateral edge 158 such that the punching and bending formation process displaces the intact edge 158 from the front face 142 of the strip 140. This process forms integral reinforcement webs 161 or gussets on each left and right side of the tab (only right web visible). Each web 161 extends outwardly from the front face of the strip to its respective left or right side of the tab in the region between the intact edge 158 and bending edge or line 159. In this form, the reinforcement webs are triangular in shape. Although not essential, the reinforcement webs support the engagement tab 150 to maintain its position under load when supporting a board in use.
The fixing strip shown in
It will be appreciated that the fixing strip 140 may be made in lengths to match the framing stud length. The material for forming a fixing strip may for example be stainless steel or mildsteel galvanized, or any other suitable material, whether metal, steel, aluminium or the like.
The alignment tab 160 is formed as before, but may perform a dual function of alignment and also as an additional engagement or locking tab or retaining clip. In this form, the alignment tab 160 is longer than it is wide (in the transverse direction relative to the longitudinal direction of the fixing strip), although this is not necessarily essential. Referring to

Referring to
In summary, the fixing system using the second form of fixing clips operates such that each fixing clip acts to support or hold both upper and lower adjacent boards against the framing. More particularly, the first engagement tab 150 supports the upper board 28a under gravity, while the second lower engagement tab 160 is bent into abutting engagement with the upper surface of the lower board 28b to clamp or hold the board in an engaged state with the engagement tabs of its respective fixing clips. In other words, each installed board is held in place by the first engagement tabs 150 of a row of fixing clips, and additionally each or at least some of the lower engagement tabs 160 of the next adjacent upper row of fixing clips.
The installation method for this form of fixing system is similar to that described with respect to
It will be appreciated that the use of the fixing components, such as nails 82, in the overlapping region may not be necessary when using the second form of fixing clip. The second lower engagement tabs 150 may be engaged with the upper surface 180 of the boards with sufficient holding power to render the use of the nails 82 as optional in some installations. Therefore, in such situations, the boards are entirely held in place on the framing by the concealed engagement tabs 150, 160 of the fixing clips.
It will be appreciated that the reinforcement web feature of the upper engagement tab may be applied to the first form of fixing clip 30. Additionally, or alternatively, the bending of the alignment tab to act as a retaining clip may be employed in the first form of fixing clip 30 if desired.
Third EmbodimentThe previous embodiments are described in the context of the fixing system when used with bevel-backed board profiles in which the rear surfaces of the boards have a sloped or angled upper portion (like is shown at 12 in
Referring to
Referring to
As shown in
Fixing components, such as nails or the like, extending through the boards in the overlapping region and into the framing to further secure the upper portion of the boards in place against the framing are shown at 82 in the embodiments of
The fixing clips described above by way of example employ rectangular engagement and alignment tabs. It will be appreciated that one or both tabs need not necessarily be rectangular in shape, and could be any other suitable shape that is capable of performing their respective functions. Rectangular tabs are utilised in the example above because of their ease of formation using a punching and bending process as is known by those skilled in the art.
It will be appreciated that the specific profile of the recesses in the rear face of the cladding boards described above is not necessarily essential. Other profiles of recesses could be employed to retain and receive the engagement tab of the fixing clip and co-operate with that tabs in a gravity-hold or hook-like engagement relationship. In the embodiments shown and described, the cladding board rests under its own weight upon the angled engagement tabs and this arrangement acts to hold the board in place due to the angular orientation of the tabs. However, in alternative embodiments the cladding boards may be provided with a slot recess extending into the board and which is dimensioned to receive and retain the engagement tab in a snug or friction fit hold.
It will be appreciated that the alignment tab of each fixing clip is not necessarily essential in some embodiments. The alignment tab does assist in the efficient installation and alignment of the cladding boards, but the fixing system could alternatively work with each fixing clip only having the engagement tab for holding the cladding boards optionally in combination with the fixing components. In other embodiments, the alignment tab is required as it operates as a lower engagement tab for assisting in holding the boards in place, with or without the assistance of fixing components.
It will be appreciated that the vertical and horizontal spacing between fixing clips, whether installed via cavity battens or directly to framing, may be varied as desired to accommodate different framing structures, cladding board sizes and the like. Preferably, the vertical spacing intervals between fixing clips is uniform to provide an even overlap of boards up the framing. The horizontal spacing intervals can be varied according to the desired level of structural integrity required.
Individual Mountable Fixing ClipsIt will be appreciated that the fixing clips 30,130,230 need not necessarily be provided in integral fixing strips of multiple spaced-apart clips. The fixing clips can alternatively be provided as individual and separate fixing clips 30,130,230 that may be individually mountable directly or indirectly to the framing, being aligned and spaced-apart vertically and horizontally, to form the rows of fixing clips.
Referring to
The various embodiments may have any one or more of the following advantages and/or benefits.
The fixing system of the invention provides greater stability in the construction of cladding board buildings and houses. The fixing clips of the fixing system are designed to hold boards in place, with nails or the like providing optional additional securement at intervals through the unexposed surface of the boards in the overlapping region. The fixing system provides greater stability of boards and provides greater resistance against the elements as it is an entirely concealed fixing system. The concealed nature of the fixing system also provides an aesthetic advantage in that there is no visible nailing. Also, boards can be pre-painted prior to installation on the framing and this may provide cost savings from an installation viewpoint. Further, the cavity batten based fixing system provides a means of enhancing the durability and life of cladding via increased drainage.
In embodiments in which the boards are held in place without the optional use of fixing components, such as nails, this can provide the benefit of reduced water penetration and resultant hydriscopic movement during construction, and allows for easy replacement of damaged boards if required post-installation.
The fixing system has been described in the context of cladding the framing of a building, but it will be appreciated that the system can also be applied to roofing, fencing, and screens, whether the framing is timber or metal. The embodiment described above is for installing cladding boards in a substantially horizontal orientation relative to the ground, although it will be appreciated that orientation of the fixing system components can be modified for fixing boards vertically or on an angle.
The foregoing description of the inventions includes preferred forms thereof. Modifications may be made thereto without departing from the scope of the invention as defined by the accompanying claims.
