Description
FACADE PANEL WITH INTEGRATED WINDOW SYSTEM
FIELD OF THE INVENTION
[001] The present invention relates to the field of construction of modular structures. More particularly, the present invention relates to the field of panel systems for use in the construction of mass timber multi-storey, modular structures.
BACKGROUND OF THE INVENTION
FIELD OF THE INVENTION
[001] The present invention relates to the field of construction of modular structures. More particularly, the present invention relates to the field of panel systems for use in the construction of mass timber multi-storey, modular structures.
BACKGROUND OF THE INVENTION
[002] Prefabricated facade wall panels are becoming increasingly commonly used in construction (for example in the construction of curtain walls for multi-storey modular buildings) due to efficiency factors ¨ often leading to possible reductions in terms of construction time and/or construction costs. Prefabricated facade panels generally allow for very quick assembly during the construction process. This can, for example, allow for a quick building envelope enclosure, which among various advantages, can reduce the risk of water damage to the overall structure (e.g.
caused by rain).
caused by rain).
[003] Using prefabricated facade panels in construction can be relatively straightforward when the facade panels are used simply to construct basic wall sections without windows/door or other such features. However, when it comes to using prefabricated facade panels to construct wall sections that also have windows, doors or other complications, additional complexities and considerations will apply.
[004] Curtain wall systems are usually made from steel or timber as frame constructions from many small elements. (Mass timber is increasingly being used in the manufacture of prefabricated facade panels for a number of reasons, including because it is generally considered to be environmentally sustainable and of relatively low cost). The cavities between the frames are usually filled with insulation and covered with wooden boards. The complexity of this construction makes it difficult to adapt to different window sizes and difficult to ensure air-tightness along all seams.
[005] Further, many of the disciplines associated with such building materials, such as steel framing, mass timber construction, wall finishes, connectors, insulation and window manufacturing have become increasingly specialised and separated, resulting in high tolerance margins and limited adaptability; the separation of these building materials disciplines, make it challenging to integrate such disciplines to develop prefabricated facade panels. Largely because of these reasons, prefabricated facade panels have not generally been used in the construction of wall sections having windows, doors or other complication features, for multi-storey modular buildings.
[006] On a typical such construction project, the windows, doors, connection hangers for insulation and various other building components are done on-site.
The mass timber façade panels and such building components are fastened/installed in weather-permitting (sometimes challenging) conditions.
These discrete trades arrive on-site and conduct their work according to the generalized instructions from manufacturers and the architectural specifications. When components, membranes, cladding, etc. are attached, the materials themselves may be exposed to the weather and material expansion differentials, which can lead to poor constructability.

DETAILED DESCRIPTION OF THE INVENTION
[0024] A
detailed description of one or more embodiments of the present invention is provided below along with accompanying figures that illustrate the principles of the invention. As such, this detailed description illustrates the present invention by way of example and not by way of limitation. The description will clearly enable one skilled in the art to make and use the invention, and describes several embodiments, adaptations, variations and alternatives and uses of the invention, including what is presently believed to be the best mode and preferred embodiment for carrying out the invention. it is to be understood that routine variations and adaptations can be made to the invention as described, and such variations and adaptations squarely fall within the spirit and scope of the invention.
For the purpose of clarity, technical material that is known in the technical fields related to the invention has not been described in detail so that the invention is not unnecessarily obscured.
[00251 Disclosed herein is a composite construction element for building multi-storey structures. More specifically, disclosed herein is a mass timber composite construction element for use in constructing a curtain wall for a multi-storey structure, which construction element is prefabricated and is to be installed/connected on the construction site. The composite construction element is generally described and illustrated herein for use in the construction of a curtain wall for a multi-storey building (i.e. as a new build"); however, it will be appreciated by one skilled in the art that the composite construction element may also be used (or adapted for use) in the construction of a curtain wall to retrofit an existing multi-storey building.
[0026]
Referring to Fig. 1, this illustrates an exploded perspective view of an exemplary embodiment of the composite facade panel of the present invention.
The composite facade panel 10 comprises an envelope structural subpanel 20 and a window subpanel system 30. The window subpanel 30 comprises the elements that typically make up a curtain wall having windows, namely: one or more windows 32; an insulation layer 34, which includes one or more corresponding openings for receiving the one or more windows 32; strapping 36; and a cladding layer 38.
Alternative configurations of the components of the window subpanel 32 are of course possible. It is also contemplated that the other component layers may be substituted or supplemented depending on the specific requirements, functionality or desired specifications for the curtain wall, as will be understood by one skilled in the art. For example, additional layers of a vapor barrier, waterproofing, additional insulation, additional cladding may be added to, or used to replace one or more of the component layers, as may be appropriate in particular circumstances. While not specifically illustrated in Fig. 1, it is also contemplated that such a composite facade panel may optionally additional incorporate one or more door elements, e.g.
where the composite panel is used to construct a wall section for a building (i.e.
rather than a curtain wall section). In a similar fashion as discussed above that a prefabricated composite facade panel can be provided that has one or more windows integrated therein, so a prefabricated composite facade panel can also be provided with an integrated door or doorway, and/or windows. it is contemplated that other complications may also be integrated into such a composite facade panel (such as electrical services and mechanical services, venting structures, etc.), as might typically be found in a multi-storey building.
[0027] It will be evident to one skilled in the art that such a prefabricated, integrated facade panel system as disclosed herein will provide for advantages in general airtightness. There will generally be minimal tolerances between the various component layers (e.g. given the integrated membranes) and the ease of on-site assembly will generally reduce errors and improve quality control issues that might otherwise be caused by variations in on-site workmanship and/or caused by difficult on-site work conditions during installation of the various component layers.
[0028] The composite facade panel 10 is also provided with an attachment means 40, for affixing the composite facade panel 10 to the structure of the building. In one embodiment, the attachment means 40 may be in the form of a clip and cleat system or a bracket system (as is known in the art), by means of which a facade panel 10 may be installed or hung onto an upper floor, such that the facade panel 10 extends down one or more floors of the building. (For example, the attachment means 40 can be configured to attach to the upper floor near the underside of the ceiling of the upper floor or near the topside of the floor or the upper floor).
[0029] As mentioned above, the composite facade panel 10 is a unitary, prefabricated panel.
[0030] Referring to Fig. 2, this shows a partially-exploded view of the envelope structural subpanel 20 and the window subpanel 30, which together make up the composite facade panel 10. in this example, the windows 32 of the window subpanel 30 are shown as having a regular pattern. The envelope structural subpanel 20 and the window subpanel 30 are affixed together to form the composite facade panel 10, which is a unitary prefabricated construction panel.
Fig. 3 illustrates another embodiment of the structural subpanel 20 and window subpanel 31, which together make up the composite facade panel. In this example, the windows 32 in the window subpanel 31 may have an irregular window pattern.
Thus, it is to be understood that the present composite facade panel system 10 is readily customizable in order to be adapted to different construction requirements and configurations.
[0031] Fig. 4 illustrates an exemplary envelope structural subpanel 20. The envelope structural subpanel 20 comprises an upper subpanel or upper beam 22, disposed at the top of the envelope structural subpanel 20 and extending substantially the length thereof; a lower subpanel or lower beam 24, disposed at the bottom of the envelope structural subpanel 20 and extending substantially the length thereof; and plurality of strengthening infill panels or spacers 26, disposed between the upper beam 22 and lower beam 24. Optionally, these components may be affixed to an internal subpanel 29, such that the components are integrated as a single subpanel. Between the strengthening spacers 26, openings may be provided to correspond with each of the plurality of windows 32. The primary function of the upper beam 22, lower beam 24 and strengthening spacers 26 is to provide structural integrity, shear stiffness, and/or structural support to the envelope structural subpanel 20 of the composite façade panel 10. The upper beam 22 and the lower beam 24 primarily provide structural support in the direction along the length of the envelope structural subpanel, whereas the strengthening spacers primarily function to provide structural support in the direction along the width of the envelope structural subpanel 20. The upper beam 22, lower beam 24 and strengthening spacers 26 may preferably be constructed from mass timber.
[0032] Fig.
5 illustrates another possible embodiment of the envelope structural subpanel 20. As shown, in this example, the strengthening spacers abut or may be affixed to the upper beam 22 and lower beam 24. These components may be integrated together into a single subpanel. Optionally, such components may be affixed to an internal subpanel 29 (not shown in Fig. 5).
[0033]
Referring to Fig. 6, this illustrates a plurality of composite façade panels 10, as they may be installed upon a multi-storey building. Portions of a number of floor slabs 50 of a multi-storey building are shown. For example, a first composite façade panel 12 may be installed on a first floor slab 52, and vertically "hung" from the end of such floor slab, such that the first composite facade panel 12 extends from the floor slab 52 to at least a second floor slab 54, i.e. the floor slab on the floor below, thus forming an external curtain wall between the first floor slab and the second floor slab. in this fashion, composite facade panels may be installed and hung from other floor slabs, thus creating a multi-storey curtain wall for the building. in this manner, the building may be provided with a curtain wall, which is affixed to the structural parts of the building (i.e. the floors), but which is otherwise structurally independent from the building, thus allowing the curtain wall to respond to movements or expansion/contraction of the building or of the façade panels.
[0034]
Although not specifically illustrated, it is contemplated that the composite facade panels may also be provided with connectors or attachment means for horizontally connecting adjacent composite facade panels, in order to form a grid-like system. Optionally, composite facade panels may also be provided with connectors or attachment means for vertically connecting composite facade panels With other composite facade panels disposed above or below thereto.
[0035] It will be apparent that the composite facade panels as described above may be used in a modularized system, for efficient assembly and installation of walls/curtain walls for a multi-storey building. Furthermore, the design of the composite facade panels is such that they can be configured/adapted and customised for different specifications.
[0036] The straight composite facade panel 10 described above may be adapted or configured for various other building features or geometries. Fig.
illustrates a number of other types of composite facade panels having various additional features. For example, corner facade panel 60 includes a corner section 62, which is used for constructing a portion of a curtain wall corresponding to a corner of a building. Another facade panel 64 may be provided with a soffit panel 66, and used for facade panels where a section of a building has an overhang.
Facade panel 64 may also be provided with a setback 68. A facade panel 64 may also be provided with a balcony or parapet panel 70, where construction of balcony/parapet is required. Other adaptations depending on the specific construction requirement for a particular building will be apparent to one skilled in the art. These facade panel examples will each potentially have the same sort of advantages discussed previously that are applicable to the straight composite facade panel 10; such prefabricated facade panels can be relatively quickly and easily assembled / connected together at a construction site, without requiring multiple specialist trades to each be involved at a construction site.
[0037] A
composite facade panel may also be optionally provided with a number of external finishes or features, such as rain screens, shading screens (canopies), railings, each of which will be constructed as to be affixed to the envelope structural subpanel 20 of said composite facade panel.
[0038]
Referring to Fig. 8, this shows the ends of a first floor slab 52 and a second floor slab 54, i.e. the ends of an upper floor and a lower floor of a multi-storey building. A first composite façade panel 12 is shown installed on or '"hung' from the first floor slab 52, via an attachment means 40. A second composite façade panel 14 is shown installed on the second floor slab 54, on the floor below.
The composite façade panels thus make up a section of curtain wall for the multi-storey building. In one embodiment, a first composite facade panel 12 may also be provided with engagement means on one or both of its top and bottom edges, for engagement with the another corresponding composite panel positioned directly above or below said first composite facade panel 12. As shown in Fig. 8, a first composite panel 12 is provided with tongue joint 74 running along the length of its bottom edge. A second composite facade panel 14 is provided with a corresponding groove 72 running along the length of its top edge, wherein such groove 72 is adapted to receive the tongue 74 of the first composite façade panel.
Thus, the first composite façade panel 12 and a corresponding second composite façade panel 14 may be matingly engaged to provide additional stability between the composite façade panels. Such interlocking façade panels may be weather-stripped to seal to one another. One other advantage of such a tongue-and-groove-type joint is that it can account for small thermal expansion/contraction effects or other movement effects, in or between the composite facade panels (e.g.
caused by temperature changes, inter-storey differential movement, concrete creep, column foreshortening and/or seismic movement). For example, in the event a façade panel expands in the vertical direction, there is generally sufficient "play" within the gap between the tongue and groove joint to permit such expansion.
[0039]
Besides the tongue-and-groove-type joint described above, other engagement means, that are known in the art, may be used for engaging a facade panel with another facade panel, whether directly thereabove, therebelow or adjacent thereto. For example, a simple butt joint closed off with a gasket around the edges of the facade panels could be used. Another possibility is to use a gutter weather seal which is often referred to in the industry as "a chicken head"
detail.
[0040]
Depending on the circumstances and desired specifications, in other embodiments, a composite facade panel may also be actually attached and secured to another vertically adjacent facade panel, such that a particular composite facade panel does not necessarily need to be attached to or hung from a floor slab so securely (such as using the attachment means). An example of such a curtain wall configuration is illustrated in Fig. 9. A third facade panel 16 is engaged with and attached to a second facade panel 14, such that it does not need to be secured in quite the same fashion to a third floor slab 56.

[00251 Disclosed herein is a composite construction element for building multi-storey structures. More specifically, disclosed herein is a mass timber composite construction element for use in constructing a curtain wall for a multi-storey structure, which construction element is prefabricated and is to be installed/connected on the construction site. The composite construction element is generally described and illustrated herein for use in the construction of a curtain wall for a multi-storey building (i.e. as a new build"); however, it will be appreciated by one skilled in the art that the composite construction element may also be used (or adapted for use) in the construction of a curtain wall to retrofit an existing multi-storey building.
[0026]
Referring to Fig. 1, this illustrates an exploded perspective view of an exemplary embodiment of the composite facade panel of the present invention.
The composite facade panel 10 comprises an envelope structural subpanel 20 and a window subpanel system 30. The window subpanel 30 comprises the elements that typically make up a curtain wall having windows, namely: one or more windows 32; an insulation layer 34, which includes one or more corresponding openings for receiving the one or more windows 32; strapping 36; and a cladding layer 38.
Alternative configurations of the components of the window subpanel 32 are of course possible. It is also contemplated that the other component layers may be substituted or supplemented depending on the specific requirements, functionality or desired specifications for the curtain wall, as will be understood by one skilled in the art. For example, additional layers of a vapor barrier, waterproofing, additional insulation, additional cladding may be added to, or used to replace one or more of the component layers, as may be appropriate in particular circumstances. While not specifically illustrated in Fig. 1, it is also contemplated that such a composite facade panel may optionally additional incorporate one or more door elements, e.g.
where the composite panel is used to construct a wall section for a building (i.e.
rather than a curtain wall section). In a similar fashion as discussed above that a prefabricated composite facade panel can be provided that has one or more windows integrated therein, so a prefabricated composite facade panel can also be provided with an integrated door or doorway, and/or windows. it is contemplated that other complications may also be integrated into such a composite facade panel (such as electrical services and mechanical services, venting structures, etc.), as might typically be found in a multi-storey building.
[0027] It will be evident to one skilled in the art that such a prefabricated, integrated facade panel system as disclosed herein will provide for advantages in general airtightness. There will generally be minimal tolerances between the various component layers (e.g. given the integrated membranes) and the ease of on-site assembly will generally reduce errors and improve quality control issues that might otherwise be caused by variations in on-site workmanship and/or caused by difficult on-site work conditions during installation of the various component layers.
[0028] The composite facade panel 10 is also provided with an attachment means 40, for affixing the composite facade panel 10 to the structure of the building. In one embodiment, the attachment means 40 may be in the form of a clip and cleat system or a bracket system (as is known in the art), by means of which a facade panel 10 may be installed or hung onto an upper floor, such that the facade panel 10 extends down one or more floors of the building. (For example, the attachment means 40 can be configured to attach to the upper floor near the underside of the ceiling of the upper floor or near the topside of the floor or the upper floor).
[0029] As mentioned above, the composite facade panel 10 is a unitary, prefabricated panel.
[0030] Referring to Fig. 2, this shows a partially-exploded view of the envelope structural subpanel 20 and the window subpanel 30, which together make up the composite facade panel 10. in this example, the windows 32 of the window subpanel 30 are shown as having a regular pattern. The envelope structural subpanel 20 and the window subpanel 30 are affixed together to form the composite facade panel 10, which is a unitary prefabricated construction panel.
Fig. 3 illustrates another embodiment of the structural subpanel 20 and window subpanel 31, which together make up the composite facade panel. In this example, the windows 32 in the window subpanel 31 may have an irregular window pattern.
Thus, it is to be understood that the present composite facade panel system 10 is readily customizable in order to be adapted to different construction requirements and configurations.
[0031] Fig. 4 illustrates an exemplary envelope structural subpanel 20. The envelope structural subpanel 20 comprises an upper subpanel or upper beam 22, disposed at the top of the envelope structural subpanel 20 and extending substantially the length thereof; a lower subpanel or lower beam 24, disposed at the bottom of the envelope structural subpanel 20 and extending substantially the length thereof; and plurality of strengthening infill panels or spacers 26, disposed between the upper beam 22 and lower beam 24. Optionally, these components may be affixed to an internal subpanel 29, such that the components are integrated as a single subpanel. Between the strengthening spacers 26, openings may be provided to correspond with each of the plurality of windows 32. The primary function of the upper beam 22, lower beam 24 and strengthening spacers 26 is to provide structural integrity, shear stiffness, and/or structural support to the envelope structural subpanel 20 of the composite façade panel 10. The upper beam 22 and the lower beam 24 primarily provide structural support in the direction along the length of the envelope structural subpanel, whereas the strengthening spacers primarily function to provide structural support in the direction along the width of the envelope structural subpanel 20. The upper beam 22, lower beam 24 and strengthening spacers 26 may preferably be constructed from mass timber.
[0032] Fig.
5 illustrates another possible embodiment of the envelope structural subpanel 20. As shown, in this example, the strengthening spacers abut or may be affixed to the upper beam 22 and lower beam 24. These components may be integrated together into a single subpanel. Optionally, such components may be affixed to an internal subpanel 29 (not shown in Fig. 5).
[0033]
Referring to Fig. 6, this illustrates a plurality of composite façade panels 10, as they may be installed upon a multi-storey building. Portions of a number of floor slabs 50 of a multi-storey building are shown. For example, a first composite façade panel 12 may be installed on a first floor slab 52, and vertically "hung" from the end of such floor slab, such that the first composite facade panel 12 extends from the floor slab 52 to at least a second floor slab 54, i.e. the floor slab on the floor below, thus forming an external curtain wall between the first floor slab and the second floor slab. in this fashion, composite facade panels may be installed and hung from other floor slabs, thus creating a multi-storey curtain wall for the building. in this manner, the building may be provided with a curtain wall, which is affixed to the structural parts of the building (i.e. the floors), but which is otherwise structurally independent from the building, thus allowing the curtain wall to respond to movements or expansion/contraction of the building or of the façade panels.
[0034]
Although not specifically illustrated, it is contemplated that the composite facade panels may also be provided with connectors or attachment means for horizontally connecting adjacent composite facade panels, in order to form a grid-like system. Optionally, composite facade panels may also be provided with connectors or attachment means for vertically connecting composite facade panels With other composite facade panels disposed above or below thereto.
[0035] It will be apparent that the composite facade panels as described above may be used in a modularized system, for efficient assembly and installation of walls/curtain walls for a multi-storey building. Furthermore, the design of the composite facade panels is such that they can be configured/adapted and customised for different specifications.
[0036] The straight composite facade panel 10 described above may be adapted or configured for various other building features or geometries. Fig.
illustrates a number of other types of composite facade panels having various additional features. For example, corner facade panel 60 includes a corner section 62, which is used for constructing a portion of a curtain wall corresponding to a corner of a building. Another facade panel 64 may be provided with a soffit panel 66, and used for facade panels where a section of a building has an overhang.
Facade panel 64 may also be provided with a setback 68. A facade panel 64 may also be provided with a balcony or parapet panel 70, where construction of balcony/parapet is required. Other adaptations depending on the specific construction requirement for a particular building will be apparent to one skilled in the art. These facade panel examples will each potentially have the same sort of advantages discussed previously that are applicable to the straight composite facade panel 10; such prefabricated facade panels can be relatively quickly and easily assembled / connected together at a construction site, without requiring multiple specialist trades to each be involved at a construction site.
[0037] A
composite facade panel may also be optionally provided with a number of external finishes or features, such as rain screens, shading screens (canopies), railings, each of which will be constructed as to be affixed to the envelope structural subpanel 20 of said composite facade panel.
[0038]
Referring to Fig. 8, this shows the ends of a first floor slab 52 and a second floor slab 54, i.e. the ends of an upper floor and a lower floor of a multi-storey building. A first composite façade panel 12 is shown installed on or '"hung' from the first floor slab 52, via an attachment means 40. A second composite façade panel 14 is shown installed on the second floor slab 54, on the floor below.
The composite façade panels thus make up a section of curtain wall for the multi-storey building. In one embodiment, a first composite facade panel 12 may also be provided with engagement means on one or both of its top and bottom edges, for engagement with the another corresponding composite panel positioned directly above or below said first composite facade panel 12. As shown in Fig. 8, a first composite panel 12 is provided with tongue joint 74 running along the length of its bottom edge. A second composite facade panel 14 is provided with a corresponding groove 72 running along the length of its top edge, wherein such groove 72 is adapted to receive the tongue 74 of the first composite façade panel.
Thus, the first composite façade panel 12 and a corresponding second composite façade panel 14 may be matingly engaged to provide additional stability between the composite façade panels. Such interlocking façade panels may be weather-stripped to seal to one another. One other advantage of such a tongue-and-groove-type joint is that it can account for small thermal expansion/contraction effects or other movement effects, in or between the composite facade panels (e.g.
caused by temperature changes, inter-storey differential movement, concrete creep, column foreshortening and/or seismic movement). For example, in the event a façade panel expands in the vertical direction, there is generally sufficient "play" within the gap between the tongue and groove joint to permit such expansion.
[0039]
Besides the tongue-and-groove-type joint described above, other engagement means, that are known in the art, may be used for engaging a facade panel with another facade panel, whether directly thereabove, therebelow or adjacent thereto. For example, a simple butt joint closed off with a gasket around the edges of the facade panels could be used. Another possibility is to use a gutter weather seal which is often referred to in the industry as "a chicken head"
detail.
[0040]
Depending on the circumstances and desired specifications, in other embodiments, a composite facade panel may also be actually attached and secured to another vertically adjacent facade panel, such that a particular composite facade panel does not necessarily need to be attached to or hung from a floor slab so securely (such as using the attachment means). An example of such a curtain wall configuration is illustrated in Fig. 9. A third facade panel 16 is engaged with and attached to a second facade panel 14, such that it does not need to be secured in quite the same fashion to a third floor slab 56.
