Description

TECHNICAL FIELD

This disclosure relates to multi-storey structures having an external facade and to methods of erecting or assembling the structure and facade.

BACKGROUND ART

Facades for multi-storey structures are known to utilise pre-fabricated modular elements that are affixed to a multi-storey structure after erection of the structure. In some forms, known methods of constructing multi-storey structures, a safety rail or scaffold is required to allow for pre-fabricated facade elements to be added to a floor at any level of a structure to provide the walls and, in some forms, windows of the structure. Known methods of erecting the multi-storey structure may comprise the steps of i) erecting a scaffold or perimeter screen ii) erecting support columns extending upwards from the ground or slab iii) building formwork for an upper floor iv) forming an upper floor v) repeating until the structure is the required height vi) removing the scaffold or perimeter screen and vii) attaching an external facade to the structure. Alternatively, known methods may include constructing a safety rail on any floor of a multi-storey structure and utilising a harness to prevent falls.

It is to be understood that, if any prior art is referred to herein, such reference does not constitute an admission that the prior art forms a part of the common general knowledge in the art in Australia or any other country.

SUMMARY

Disclosed is a method of erecting a multi-storey structure having a facade disposed around at least a portion of a perimeter of the multi-storey structure, wherein during construction, at least a portion of the facade is disposed to extend beyond an upper work area of the structure and forms at least part of a safety barrier for that work area.

In some forms the facade is formed from a plurality of panels, and the panels form at least part of the safety barrier.

The method may have the benefit of allowing construction of a multi-storey structure without requiring an expensive scaffolding or perimeter screen to be erected. The method may also have the benefit of enhancing safety. This is because the facade may act as a perimeter screen or scaffolding, preventing falls from the structure. The method means the outer facade or outer walls of the structure and the scaffolding may be essentially integrated.

In some forms, disclosed is a method for erecting a multi-storey structure having a facade, the method comprising locating a plurality of facade panels around at least a portion of the perimeter of a first level of the multi-storey structure, the facade panels having two opposing faces with an upper floor connection member extending from a first opposing face of the panel; orienting the facade panels such that the upper floor connection members extend inwardly into the multi-storey structure; forming an upper floor at the height of the upper floor connection members, such that the upper floor connection members engage the upper floor to connect the upper floor with the plurality of facade panels.

In some forms the facade panels act both as a fall prevention system and as the permanent facade panels for the structure. In some forms the facade panels include a section that is configured to be located below a floor of the structure and a section that is configured to be located above the floor of the structure.

In some forms, the facade panels have a top edge and a bottom edge and in use the upper floor connection members are located intermediate the top edge and the bottom edge.

The upper floor connection member being intermediate the top and bottom edges may have the benefit of extending the facade panel above a new floor once the floor is cast, meaning a worker or other person standing on the new floor is fenced in by the facade panel to provide some protection.

In some forms the facade panels are composed of a material sufficiently strong to act as a fall prevention and as a permanent facade including windows.

In some forms the facade panels prevent a person falling from the structure during and after building.

Further, disclosed is a facade panel comprising two opposing faces, and in situ top and bottom edges; and, a connection member extending from the a first opposing face of the facade panel, the connection member being located intermediate the top and bottom edges.

DETAILED DESCRIPTION

In the following detailed description, reference is made to accompanying drawings which form a part of the detailed description. The illustrative embodiments described in the detailed description, depicted in the drawings and defined in the claims, are not intended to be limiting. Other embodiments may be utilised and other changes may be made without departing from the spirit or scope of the subject matter presented. It will be readily understood that the aspects of the present disclosure, as generally described herein and illustrated in the drawings can be arranged, substituted, combined, separated and designed in a wide variety of different configurations, all of which are contemplated in this disclosure.

Disclosed is a method of erecting a multi-storey structure having a facade disposed around at least a portion of a perimeter of the multi-storey structure, wherein during construction, at least a portion of the facade is disposed to extend beyond an upper work area of the structure and forms at least part of a safety barrier for that work area.

In some forms the facade is formed from a plurality of panels, and the panels form at least part of the safety barrier. In some forms the facade includes support elements and infill members connected to and supported by the infill members, and wherein at least the support elements form at least part of the safety barrier. In some forms the infill members also forms part of the safety barrier.

In some forms the method further comprises erecting a removable barrier material that forms part of the safety barrier. In some forms the barrier material is disposed on an inner side of the panels. In some forms the infill members are connected to the support elements either with the barrier material or after removal of barrier material.

In some forms of the method at least one further floor of the structure is erected over the upper work area, with the or each further floor forming a respective subsequent upper work area of the structure, and wherein at least a portion of the facade is disposed to extend beyond at least one of the subsequent work areas and forms at least part of a safety barrier for that subsequent work area.

In some forms at least one floor is formed after the facade is constructed, the floor being formed such that the floor connects the floor with the facade. In some forms the facade includes a connection region. In some forms upon forming the floor, the floor encases the connection region.

In some forms in erecting the structure at least a portion of the facade is constructed prior to the uppermost floor such that the facade extends above the height at which a next floor will be built to form a safety barrier for the next floor.

In some forms the safety barrier is at least 1.5 m above the next floor.

Also disclosed is a facade panel configured to be disposed around at least a portion of a perimeter of a multi-storey structure, wherein during construction, at least a portion of the facade is disposed to extend beyond an upper work area of the structure and forms at least part of a safety barrier for that work area.

The method and the panel allow workers to safely work on the upper work area without requiring independent fall barriers or scaffolding. The facade in some forms is designed such that during construction at least a portion of a facade panel forming the facade extends above the work area to prevent falling from the work area.

In some forms, disclosed is a method comprising locating a plurality of facade panels around at least a portion of the perimeter of a level of the multi-storey structure, the facade panels having two opposing faces with an upper floor connection member extending from a first opposing face of the panel; orienting the facade panels such that the upper floor connection members extend inwardly into the multi-storey structure; forming an upper floor at the height of the upper floor connection members, such that the upper floor connection members engage the upper floor to connect the upper floor with the plurality of facade panels.

The facade panels may in some forms be located around the perimeter of a ground level or an upper level of a structure.

In some forms, the facade panels have a top edge and a bottom edge and in use the upper floor connection members are located intermediate the top edge and the bottom edge.

In some forms, the upper floor connection members comprise a hook or bar or other formed connection extending from the first opposing faces of the panels.

In some forms, the upper floor connection members are affixed with the first opposing faces of the panels. In some forms, the upper floor connection members are welded to the first opposing faces of the panels.

In some forms the upper floor connection members are bolted to the first opposing faces of the panels.

In some forms the method further comprises attaching a bottom edge of a plurality of second storey facade panels to a top edge of the plurality of facade panels.

In some forms, the facade panels are located adjacent one another.

Also disclosed is a facade panel comprising two opposing faces, and in situ top and bottom edges; and a connection member extending from the a first opposing face of the facade panel, the connection member being located intermediate the top and bottom edges.

The connection member is configured to engage or connect with an upper floor of the multi-storey structure such that the facade is built in to the floor. This provides added strength to the facade and also allows the facade to provide fall prevention during building.

In some forms, the connection member is bolted to the first opposing face. This allows for a panel to be removed and replaced if it is damaged. The panel can be unbolted from the floor and removed.

In some forms, there is further panel connection means located at the upper or lower edge of the facade panel. This may allow for the panel to be attached with a panel above or below to allow for further storeys of the structure to be built.

In some forms the connection member comprises a hook or bar extending from the first opposing face. In some forms the connection member is bolted or removably fixed to the first opposing face.

In some forms in which the structure is a multi-storey parking structure, the facade panel is composed of a material sufficiently strong to withstand a vehicle colliding with the facade.

In some forms the facade panel further comprises a support section positioned to extend inwardly into the structure in use. In some forms the support section includes a wheel stop extending upwardly from the support section. In some forms the support section includes a crash barrier extending upwardly from the support section.

In some forms the facade panels are composed of structural steel. In some forms the facade panels include ventilation openings. In some forms the facade panels are in the form of slatted, latticed or perforated steel. In some forms the facade panels are decorative.

In some forms the section of the facade panel above the connection member acts as a fall prevention barrier.

In some forms the facade panel comprises a structural frame and an external face engaged with the structural frame. In some forms the external face is waterproof. In some forms the facade panel further comprises an internal face engaged with the structural frame. In some forms insulation is located between the external and internal faces. In some forms the facade panel includes a window or glass.

In some forms the facade panel may be a solid composite panel.

In some forms the facade panel is composed aluminium, glass, a combination of aluminium and glass, aluminium, a composite material, concrete, steel, steel and glass or any other construction material. In some forms the facade panel may be load bearing. In some forms when the panel is load bearing it is composed of concrete, structural steel or other load bearing material.

In some forms the panels are configured to act as a fall prevention system and the permanent facade of the structure.

In some forms, disclosed is a facade framework for constructing a structure having an outer facade, the framework comprising an inner frame, an outer frame spaced apart from the inner frame and connected thereto, a facade panel of the outer facade being affixed with the inner frame.

In some forms the facade panel comprises a window or wall.

In some forms, disclosed is a modular building system for building a multi-story structure, the system comprising modular units having an outer face wall portion, and at least one of a second wall portion and a floor portion.

Referring now to FIG. 1, disclosed is a method of constructing a multi-storey building such an apartment building or high-rise structure, the structure having a facade. The multi-storey structure 10 comprises a plurality of facade panels 12 forming an outer facade 13 of the multi-storey structure. The floors 14 of the multi-storey structure are contained within the facade 13. The facade panels 12 include a panel engagement section 15 which is configured to allow a facade panel 12 to be engaged with a facade panel above or below within the outer facade 13. The facade panels 12 further include a floor connection section 17 which is adapted to connect or engage a floor 14 with the facade panel 12.

The multi-storey structure 10 is constructed by locating a lowermost level 18 comprising a plurality of facade panels 12 about a lower floor 19 of the structure 10. The lowermost facade panels may be located at ground level or above ground level on a first floor of the structure or intermediate the ground and a first floor. The panels 12 extend upwardly to a height at or above the lower floor or ground level of the structure. An upper level 20 comprises a plurality of facade panels 12 engaged with the lowermost facade panels. The upper level facade panels 12 extend upwardly well above the height of a person. A floor connection section 17 is located on the interior face of the facade panels 12. Once the upper floor facade panels 12 are positioned, formwork and supporting struts or similar for a floor are put in. The floor is then built, constructed or cast around the floor connection section 17 such that the floor and the panel are engaged. A worker can then position the next floor facade panels 22. The process continues until the structure is the required number of storeys.

As can be seen, throughout the process, the facade 13 is positioned before the upper floors are built and extends higher than the uppermost floor. This allows the facade to act as a fall prevention screen and allows for an upper work area to be safely positioned on the uppermost floor. Once the project is completed the facade remains as an outer wall of the structure.

The floor may be supported by the construction. In some forms the floor may be supported by the facade panels. In this form the panels are load bearing and are composed of material that can be load bearing. In alternative forms the floors may be supported by independent steel or concrete columns.

The floor may be composed of any flooring material. In some forms the floor is formed of precast concrete. In other forms the floor comprises a steel form with concrete cast thereon. In some forms the floor comprises reinforced concrete. In some forms the floor comprises structural steel and decking. In some forms the floor comprises structural timber, in some forms the floor is composed of a composite material.

Turning to FIGS. 2-4, the process is shown in closer detail. In FIG. 2 the first, second and third floors have been built and a worker is standing on each of the second and third floors. An upper work area may exist on the uppermost floor, with the facade extending above the uppermost floor.

The facade panels 12 include an uppermost facade panel 12′ which includes a floor connection section 17. The floor connection section 17 is in the form of a connection member 25 extending from a connection plate 26. The connection member 25 may be welded or otherwise connected to the connection plate 26. In alternative embodiments the connection member may extend directly from the facade. In some forms the connection member comprises re-bar.

As shown in FIGS. 2-4, a brace 28 is positioned to hold and level the facade 12. A brace connector 30 is located on the facade panel to connect the brace 28 with the facade panel 12.

Fixed glass, a window or opening 29 extends through the facade panel 12. In some forms the windows may be any ordinary window, opening, door, fixed glass or other material.

An additional facade panel 12″ is affixed above facade panel 12′. The floor connection section extends inwardly into the structure above the head height of a worker. A formwork or other support 27 may be erected to allow the workers to build an upper floor 14′ at the height of the floor connection section.

In some forms the facade panel may be composed of glass, steel, aluminium, composite, concrete or any other building material or combination of building materials.

Referring to FIGS. 5-6, the facade panels of the present disclosure include a floor connection section 17 that is located intermediate the upper end 31 and lower end 32 of the facade panels 12. In the illustrated form the connection section 17 comprises a connection member 25 in the form of a re-bar projection or a plurality of re-bar projections. The connection member 25 extends from a connection plate 26 and is welded thereto. Alternative connection means are available or in some not-illustrated forms the connection member 25 may be integral with or welded to the panel 12.

Fixed glass, other material or the window 29 or opening such as a door or louvre panel is sufficiently well supported by the facade panel 12 to allow for safe construction.

Referring now to FIGS. 7-10, disclosed is a facade panel 40 for a structure. The facade panel may be used to form the perimeter facade of a structure. Turning to FIG. 7, the facade panel in the illustrated form comprises a structural frame 42. The structural frame comprises vertical supports 43 and horizontal webs 44 and may be composed of wood, steel, aluminium or other alternative construction materials. A window 46 extends through the facade panel. The facade panel further includes an external face 47. In some forms the external face 47 is composed of an external wall or cover that may be waterproof. A cavity 48 is located within the panel 40 and may contain insulation.

Turning to FIGS. 8-10, the facade panel 40 has an external face 47 and an internal face 49 in between which is a cavity 48 that may contain insulation. The external face may be waterproof and may be composed of glass, non-combustible cladding, cement sheet or board, aluminium or any other structural material for the external facade of a building. The internal face 49 may comprise plaster board or an alternative interior facade material. A window 46 may extend through the panel.

In some forms, the panels have a 2.5-3 m height with the floor connection member being located approximately ⅔ of the way up the facade panel such that the facade panel extends both above and below the floor, allowing for safety and meaning the connection between facade panels is at a different height than the connection between floor and facade panel. In some forms, therefore, a handrail or fence of approximately 1 m to any height is produced by the construction method without requiring additional construction of a handrail. The handrail then forms a portion of the wall structure. In alternative embodiments the connection between facade panels may be at the same height as the connection between floor and facade panels.

During construction, in some forms the panels 12 are lifted into position using a crane. A hook may be incorporated into the panel 12 to allow this connection. As seen in FIG. 1 and FIG. 6, one or more crane hooks 35 may be positioned on the panel 12.

Referring now to FIG. 11, disclosed is a second embodiment of a facade panel for use in of constructing a multi-storey building, the structure having a facade. The multi-storey structure 1 comprises a plurality of facade panels 112 forming an outer facade 13 of the multi-storey structure. The floors 114 of the multi-storey structure are contained within the facade 113. The facade panels 112 include a panel engagement section 115 which is configured to allow a facade panel 112 to be engaged with a facade panel above or below within the outer facade 113. The facade panels 112 further include a floor connection section 17 which is adapted to connect or engage a floor 114 with the facade panel 112. The facade panel includes a safety barrier 118 which comprises an upper section of the facade panel 112. The safety barrier 118 comprises an upper portion of the panel above the floor connection section 117.

Similarly to the earlier embodiment, the multi-storey structure 110 is constructed by locating a lowermost level 118 comprising a plurality of facade panels 112 about a lower floor 119 of the structure 110. The lowermost facade panels may be located at ground level or above ground level on a first floor of the structure or intermediate the ground and a first floor. The panels 112 extend upwardly to a height at or above the lower floor or ground level of the structure. A upper level 120 comprises a plurality of facade panels 112 engaged with the lowermost facade panels. The upper level facade panels 112 extend upwardly well above the height of a person. A floor connection section 117 is located on the interior face of the facade panels 112. Once the upper floor facade panels 112 are positioned, formwork and supporting struts or similar for a floor are put in. The floor is then built, constructed or cast around the floor connection section 117 such that the floor and the panel are engaged. A worker can then position the next floor facade panels 122. The process continues until the structure is the required number of storeys.

As can be seen, throughout the process the safety barrier section 118 acts in place of a supplementary handrail and protects workers building a floor or otherwise accessing the upper portion of the facade. In addition, facade 113 is positioned before the upper floors are built. This allows the facade to act as a fall prevention screen. Once the project is completed the facade remains as an outer wall of the structure.

Turning to FIGS. 12 and 13, the process is shown in closer detail. In FIG. 12, two floors have been constructed and a worker is standing on the lower floor. The facade panels 112 include a safety barrier section 118 and a floor connection section 117. The safety barrier 118 is formed of the upper region of the facade panel. The floor connection section 117 is in the form of a connection member 125. The connection member 125 may be welded to the facade, bolted to the facade, or connected via a connection plate that may be welded or bolted to the facade. In alternative embodiments the connection member may extend directly from the facade without use of a connection plate. In some forms the connection member comprises re-bar. In some forms the rebar of the connection member is formed with the precast concrete and may comprise L-shaped rebar extending outwardly from the precast concrete. In alternative embodiments the connection member may extend directly from the facade. In some forms the connection member comprises re-bar. In alternative embodiments the safety barrier 118 may be engaged with the panel.

In the illustrated form, formwork 124 and a prop 134 are included to allow for construction of the structure.

As shown in FIG. 13, a floor 114 has been formed about each of the lower connection sections 117 and is ready to be formed about the uppermost connection section. A worker utilising the uppermost floor or standing on an upper work area is protected by the safety barrier 118 that extends upwardly above the floor as it is being constructed.

As shown best in FIG. 14, the facade panels of the present disclosure include a floor connection section 117 that is located intermediate the upper end 131 and lower end 132 of the facade panels 112. That is, the floor connection section divides the safety barrier 118 from the lower facade panel. In the illustrated form the connection section 117 comprises a connection member 125 in the form of a re-bar projection or a plurality of re-bar projections. The connection member 125 extends from the floor connection section 117. Further, a facade panel connection system 136 comprising an upper connection member 137 and a lower connection recess 138 may be provided. It is clear that the facade connection section 136 may be in any form. In some forms a slurry or epoxy may be utilised and inserted in a cavity for a protrusion to be inserted and adhered into.

As shown in FIG. 15, a window or opening 126 extends through the facade panel 112. In some forms the windows may be any ordinary window, opening or door. In some forms the windows extend through a lower portion of the facade panel 112 while the upper portion of the facade panel 112 comprises the safety barrier 118. It will be clear that in some forms some or all panels do not include a window.

As shown in this illustration, the connection section 117 may comprise a ledge 139 extending inwardly from the facade panel 112. In this form, the connection section 117 and panel 112 form a T shape. The ledge may in use be utilised as a walkway during construction. The safety barrier 118 is positioned to protect workers on this walkway or building the floor about the floor connection member 117 or otherwise positioned near the upper areas of the facade panel. It will be clear that this ledge is not essential to the process of building.

In some forms, the panels have a 2.5-3 m height with the floor connection member being located approximately ⅔ of the way up the facade panel such that the facade panel extends both above and below the floor, allowing for safety and meaning the connection between facade panels is at a different height than the connection between floor and facade panel. In some forms, therefore, a handrail or fence of approximately 1 m to 1.5 m or any other height is produced by the construction method without requiring additional construction of a handrail. The handrail then forms a portion of the wall structure.

During construction, in some forms the panels 112 are lifted into position using a crane. A hook may be incorporated into the panel 112 to allow this connection. As seen in FIG. 11, one or more crane hooks 135 may be positioned on the panel 112.

Referring now to FIG. 16, disclosed is a further embodiment of a facade panel for use in constructing a multi-storey building, the structure having a facade. As in the first embodiment, the multi-storey structure 110 comprises a plurality of facade panels 112 forming an outer facade 113 of the multi-storey structure. The floors 114 of the multi-storey structure are contained within the facade 113. The facade panels 112 include a panel engagement section 15 which is configured to allow a facade panel 112 to be engaged with a facade panel above or below within the outer facade 113. The facade panels 112 further include a floor connection section 17 which is adapted to connect or engage a floor 114 with the facade panel 112. The facade panel includes a safety barrier 118 which comprises an upper section of the facade panel 112. The safety barrier 118 comprises an upper portion of the panel above the floor connection section 117.

Referring now to FIG. 16, an alternative embodiment of the method is shown, in this case in constructing a parking structure. In this embodiment, disclosed is a method of constructing a multi-storey building such as a vehicle parking structure, the structure having a facade. The multi-storey structure 210 comprises a plurality of facade panels 212 forming an outer facade 213 of the multi-storey structure. The floors 214 of the multi-storey structure are contained within the facade 213. The facade panels 212 include a panel engagement section 215 which is configured to allow a facade panel 212 to be engaged with a facade panel above or below within the outer facade 213. The facade panels 212 further include a floor connection section 217 which is adapted to connect or engage a floor 214 with the facade panel 212.

The multi-storey structure 210 is constructed by locating a plurality of lowermost facade panels 218 about a lower floor 219 of the structure 210. The lowermost facade panels may be located at ground level or above ground level on a first floor of the structure. The panels extend upwardly to a height above the lower floor or ground level of the structure. A plurality of upper floor facade panels 220 are engaged with the lowermost facade panels 218. The upper floor facade panels 220 extend upwardly well above the height of a person. A floor connection section 217 is located on the interior face of the facade panels 220. Once the upper floor facade panels 220 are positioned, formwork and supporting struts or similar for a cast concrete floor are put in. The concrete floor is then cast around the floor connection section 217 such that the floor and the panel are engaged. A worker can then position the next floor facade panels 222. The process continues until the structure is the required number of storeys.

As can be seen, throughout the process the facade 213 is positioned before the upper floors are built. This allows the facade to act as a fall prevention screen. Once the project is completed the facade remains as a decorative outer screen. In some forms the facade 213 may be sufficiently strong to act as a crash barrier and prevent vehicles driving off the structure.

Turning to FIGS. 17-19, the process is shown in closer detail. In FIG. 17 the first and second floors have been built and a worker is standing on the second floor on an upper work. The facade panels 212 include an uppermost facade panel 212′ which includes a floor connection section 217. The floor connection section 217 is in the form of a connection member 225 extending from a connection plate 226. The connection member 225 may be welded or otherwise connected to the connection plate 226.

In FIG. 18, an additional facade panel 212″ is affixed above facade panel 212′. The floor connection section extends inwardly into the structure above the head height of a user. A formwork or other support 227 may be erected to allow the workers to build an upper floor 214′ at the height of the floor connection section.

Referring to FIGS. 20-23, the facade panels of the present disclosure include a floor connection section 217 that is located intermediate the upper end 231 and lower end 232 of the facade panels 212.
