Facade and/or roof including a sealing strip with a filling piece
A facade and/or light roof including a device for drainage, especially of inclined and roof glazing in post and beam construction, and including a seepage water gutter or seepage water groove within the beam section and post section, and at least one condensation gutter or condensation groove on the beam section, is characterized in that the condensation gutter or condensation groove of the beam section (2) is guided directly into the seepage water groove of the post section (1), and in that this region is sealed by a filling piece (25, 1025, 1250).
This application is a continuation of U.S. patent Ser. No. 10/447,707, filed on May 29, 2003 and International Pat. Appln. No. PCT/EP01/14833, filed on Dec. 15, 2001, which claims priority from German Pat. Appln. No. 200 21 878.6, filed on Dec. 29, 2000.
BACKGROUND OF THE INVENTIONThe invention relates to a facade and/or a roof that includes a sealing strip with a filling piece.
In the design of facades and light roofs, condensation-collecting gutters are principally located on the beam sections which, separated from the seepage water drain, carry away the condensation in separate gutters or cavities of the post sections or sealing systems. The principal reason for this is that the inner pane level or filler level forms the critical sealing level so as to prevent the passage of interior air into the pane rabbet of the facade as far as possible. Combining the condensation gutter with the seepage water drain would automatically let warm interior air into the groove which, in the case of insulating glass panes, would increase the danger of water vapor diffusing into the space between the panes.
U.S. Pat. No. 5,797,225 is directed to a sloped roof and head. This patent illustrates a sloped roof design and uses beam and post technology.
U.S. Pat. No. 4,680,950 is directed to rafters with interval drainage.
The aforementioned designs are not cost-effective to construct. Accordingly, it is the object of the invention to develop a cost-effective drain for water condensation. In particular, an object if the invention is to preclude any exchange of air between the interior and the glass rabbet of the facade or of the light roof in a cost effective manner.
SUMMARY OF THE INVENTIONBroadly, the condensation gutter of the beam section is guided directly into the seepage water groove of the post section and sealed in this area by a filling piece. The filling piece is preferably designed to prevent any exchange of air while allowing condensation to pass through. The water then is removed from the structure through at least one gutter in the post sections.
Use of these filling pieces is advantageous in those facade and light roof designs in which the condensation gutters are located in the seals for mounting the glass, and in designs in which the condensation gutters are attached in one piece to the facade sections themselves, or by using accessory sections.
The filling piece is comprised preferably of fibers, specifically in a design in which the fibers are arranged layered longitudinally in the direction of flow, or chaotically intertwined or felted. The fibers are made preferably of fiberglass or plastic, especially polyamide.
Use of a suitably fine filter structure in the filling pieces prevents any exchange of air between the interior and the drainage level. The diffusion of vapor through joints in a sealing system is not increased or negatively affected by these filling pieces. When the capillaries and spaces between fibers are filled with liquid, any vapor diffusion in this area is minimized or reduced to zero.
In one embodiment, at least one sealing strip of the beam sections and/or post sections has at least one drainage gutter, preferably, a condensation gutter. The condensation gutter is preferably molded onto the sealing strip in one piece.
The condensation gutter of the sealing strip is of a visually attractive and functional design, preferably rectangular, and preferably dimensioned according to the subjects of the additional subclaims such that it is in an especially advantageous relationship relative to the other sealing strips of the post sections.
The seals are made of an elastic material, may be easily modified using simple tools such knives and shears, and ensure a high level of sealing without special demands being placed on the worker.
The condensation gutter on the sealing strip of the stay bar visually balances the height differences of the seals relative to the post.
These and other objects, features and advantages of the present invention will become more apparent in light of the following detailed description of the preferred embodiments thereof, as illustrated in the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
The faces of post section 1 and beam section 2 each have a center rib 100 for the attachment of caps 101. These caps hold in-filling items such as panes, for example insulating panes 102.
Beam section 2 is clinched at the ends such that the section wall 3, which faces the insulating glass pane and forms the base for the seepage water groove 4 and sealing groove 5, rests when assembled on the sealing groove 6 of post section 1.
Viewed from the building side of the facade outward, sealing groove 6 of post section 1 is located above cavity 7. A sealing groove 6 and a cavity 7 together delimit a seepage water groove 8 of post section 1.
In an alternative variant shown as an example in
Together with the actual glass mounting region 10a and the seal base 10b of beam section 2, the sealing strip 10 advantageously has a condensation gutter 11 molded on as a single piece to glass mounting region 10a, the gutter being preferably rectangular.
Condensation gutter 11 together with the groove wall facing the sealing body of sealing strip 10 adjoins the outer surface of beam section 2 forming a seal. The groove base 12 (see
Sealing strip 10 is guided into the region of sealing strip 13 of post section 1 where it rests against a sealing corner piece 14, to which the glass mounting seal 13 of post section 1 is attached or joined.
Sealing corner piece 14 has an extension 15 matching condensation gutter 11 and interfacing with sealing strip 10 of post section 2, which extension encloses condensation gutter 11 laterally and from the bottom, thereby supporting and aligning it.
Sealing corner piece 14 includes a condensation gutter facing the beam section, which gutter discharges in the alignment region of sealing strip 13 into a closed hollow channel from which an outlet 16 is guided downward, passing through groove base 17 of sealing groove 6 and discharging into cavity 7. Alternatively, outlet 16 discharges into sealing groove 9, which is open at the bottom. In this case, outlet 16 may be eliminated so that only one outlet hole is present in the sealing body of sealing corner piece 14.
The facade designs with the new seal shown in
Sealing corner piece 20 includes a type of base which engages both sealing groove 5 of the beam section and sealing grooves 6, 9 of the post section and is fixed there by a form-fitting shape.
In addition, sealing corner piece 20 has a channel aligned with condensation gutter 11 and extending this gutter, which channel passes through the leg of the sealing corner piece which is aligned with sealing strip 21.
As a result, seepage water gutter 8 of the post section is directly connected to the condensation drainage system thereby directly draining the condensation directly into the seepage water drainage system.
Sealing corner piece 20 may have a drain extension for seepage water groove 8.
In
This approach reduces the exchange of air between seepage water groove 8 and condensation gutters 11, 18. For this purpose, a fibrous filter insert (filling piece) 25 is inserted into the channel that connects the condensation gutters to seepage water gutter 8 of the post section, which filter insert blocks the exchange of air while at the same time diverting the collecting condensation into the seepage water drain through adhesion and capillary action.
Both of the two different drainage systems of
For inclined surfaces, sealing strip 10 along with its attached integrated gutter 11 for beam section 2 can be located on the top side of the beam section. In the case of lesser inclinations of the roof surfaces or facade surfaces, this seal may also be located along both sides of the beam section. The same applies also to facades in which condensation generated by the condensation gutter which appears at the top side of the beam sections may be covered and carried away.
In contrast to
In
As in
Sealing end piece 26 has a smooth surface facing sealing strip 13, against which surface glass mounting seal 13 may be mounted to form a tight seal. As has already been shown in
Either drainage outlet 16, or drainage extension 22 together with drainage channel 27 sealed by filling piece 25, may be located on sealing corner piece 14, or alternatively, on sealing corner piece 20.
To implement separate drainage of condensation, sealing end piece 26 may be fitted with outlet 16, or in the event condensation is combined with the seepage water, with drainage channel 27 and filter insert (filling piece) 25.
The same applies to
In place of sealing corner pieces or sealing end pieces, sealing strip 10 together with condensation gutter 11 may extend continuously into the overlap region of beam 2 and post 1 (not shown here). Sealing strip 13 of the post section is then guided under pretension to the outer surface of condensation groove 11, an adapter piece being inserted into condensation gutter 11 in the region of sealing strip 13, which adapter piece both equalizes the overall height up to the glass support and seals condensation gutter 11 so as to allow drainage of condensation into space 9 under sealing strip 13, or into cavity 7 via a punched hole in the groove base of condensation gutter 11.
The adapter piece may also be in the form of a channel in which filling piece 25 is located which enables drainage into the rabbet or seepage water groove 8.
Especially in this latter embodiment, but also in the embodiments of
The following discussion describes in more detail the design of the sealing strips, specifically the sealing strips with an attached or molded-on drainage channel.
The sealing body or glass mounting region 10a has a height “a” viewed from plane X (i.e., the upper edge of sealing groove 5), while the seepage water groove has the dimension “b” starting from plane X up to the lower edge of groove base 130. The effective overall height “H” of sealing strip 13 for post section 1 is composed of the height of the glass mounting region plus the dimension “b” of the seepage water groove, that is, “a+b.”
Dimensions a and b are chosen such that groove base 130 of the seepage water groove rests on the upper edges of sealing groove 6 of the post sections. Groove wall 200 then rests vertically on groove base 130, and in this particular embodiment forms part of the support surface for sealing strip 13.
In one advantageous embodiment, the height “h” of groove wall 200 is equal to the dimension “b” of condensation gutter 11.
The applicable formula is: H=a+b.
In
Rabbet reduction section 220 has a height b which in an especially advantageous embodiment of groove wall 200 matches seal 10.
In this configuration, sealing strip 21 may run continuously up to the groove rib or groove base 12 of sealing strip 10, the seal base of sealing strip 21 along with condensation gutter 11 being removed in the overlap region. The drainage channel thus produced is filled by filter insert (filling piece) 25, or sealed by a filling piece.
This feature ensures that there is either a condensation drain into seepage water groove 8 or a cavity under sealing strips 7, 9 of the post section.
Seal molding 230 leaves a free channel free so as to allow a punched hole in the base of condensation water groove 11 to be accessible to drain the condensation.
Unlike the configuration in
The closed attachment surface is formed by seal moldings 230, 240 and allows sealing strip 13 to form a tight seal against sealing strip 10 or condensation gutter 11. The invention is also suitable for cover designs.
The insulating glass panes 1104 are attached by cover sections 1101 for the post, and by cover sections 1102 for the beam, as well as by retainers 1103.
Post cover seal 1004 has seepage water grooves 1006, 1007 which are delimited by the sealing wall enclosing the helical groove of the cover section and by the wall of the glass mounting region.
Post cover seal 1004 includes a seal base 1008 which is mounted onto cover section 1003 via helical channel K, and extends along the two outer sides of post section 1001 facing the insulating glass pane and under insulating glass panes 1104 where the seal base rests, supporting glass mounting regions 1009. Walls 1010 between each seal base 1008 below insulating glass pane 1104 and the region of seal 1004 located over cover section 1003 form the groove base for seepage water grooves 1006 and 1007.
The glass mounting regions 1009 are connected to seal base 1008 by integral hinges 1105 along the longitudinal edges and are thus easily detached from this base. In the separation level 1011 between seal base 1008 and glass mounting region 1009, a form-fitting attachment—here a type of slot-and-key joint 1106—may be located up to the integral hinges on the edge in the longitudinal axis of the sealing strand or sealing strip.
Walls 1010 forming the groove base for the seepage water grooves are situated significantly below separation level 1011, but are at least flush with this level. Walls 1010 are connected to each other by additional sealing walls which enclose the helical channel.
Beam cover seal 1005 is also of a one-piece design but has a “two-piece” function,” the seal base 1012 being designed as sealing strips which are connected to glass mounting region 1013 by at least one integral hinge on the longitudinal side. If needed, form-fitting means—here of the type of slot-and-key joint 1106—are also provided in separation level 1011 to align the base 1012 on glass mounting region 1013. Besides integral hinge 1105, there is no other connection between seal base 1012 and glass mounting region 1013.
Glass mounting seal or cover seal 1005 has seepage water grooves 1014, 1015. These grooves are formed by walls 1016 which extend above separation level 1011 between glass mounting regions 1013 and the region of the seal covering helical channel K. The lower level of walls 1016 is aligned with separation level 011 and the lower wall of glass mounting region 1013.
In addition, on the outside, when viewing the beam section in the installed position, there is a condensation gutter 1017 molded onto the glass mounting regions 1013 of the beam cover seal. At least one such condensation gutter 1017 is provided, and preferably two condensation gutters 1017 are molded on.
In the embodiment of
The wall of condensation gutter 1017b forming the groove base is flush with separation level 1011, that is, when condensation gutter 1017 is present, the notch along post cover seal 1004 need only be implemented along the entire width of glass mounting region 1013 including condensation gutter 1017. Both condensation gutter 1017 and seepage water grooves 1014, 1015, including glass mounting region 1013, thus rest on seal base 1008 of post cover seal 1004.
As in
The embodiment of
This arrangement allows the condensation from condensation gutter 1017 to drain into this cavity 1018. Post cover seal 1019 is guided into the base region of a facade, or into the drainage region of a light roof, thus providing a simplified means of separate drainage for seepage water and condensation. Joining cavity 1018 to condensation gutter 1017 is easily implemented by punching through the groove base of condensation gutter 1017 in the assembled state.
Glass mounting region 1013, including at least one condensation gutter 1017, is positioned simply by notching glass mounting region 1009 of post cover seal 1004, 1019. Depending on the overlap of the beam cover seal on the post cover seal, seal bases 1012, 1021 are back-notched from glass mounting region 1013.
Particularly because of the fact that condensation groove 1017 aligns with seepage water grooves 1014, 1015 of beam cover seals 1005, 1021, that only notching of the post section is required and the seal is readily ensured.
The two drainage water systems for condensation and for seepage water are joined by condensation gutter 1017. To prevent the exchange of air between interior air and the facade glass rabbet, filling piece 1250 is inserted into the condensation groove in the overlap region of the beam and the post, as in
Filling piece 1250 comprises a material which prevents the passage of air, while allowing condensation to pass through and discharge into the seepage water region of the post sections.
Sealing adapter 1240 is preferably made of the same material as the seals themselves in order to ensure sealing against the glass in the region of the condensation passage. As with filling piece 1250 in
Filling piece 25 in
Alternatively, hollow fibers 1252 may also form the body of the filling piece, the capillaries being provided both by the space between fibers and by the hollow fibers themselves.
Use of these filling pieces is appropriate for all facade designs in which condensation is combined with the seepage water.
In the event filling pieces 25, 1025 do not have sufficient elasticity to allow them to be appropriately adapted to the sealing pressures of the glass mounting seal, provision is made to locate a sealing pad or sealing strip 1253 on the side of the filling piece facing the glass pane.
