  • FIG. 1 this illustrates an exploded perspective view of an exemplary embodiment of the composite fagade panel of the present invention.
  • the composite fagade 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.
  • a composite fagade 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).
  • a prefabricated composite fagade panel can be provided that has one or more windows integrated therein, so a prefabricated composite fagade panel can also be provided with an integrated door or doorway, and/or windows.
  • other complications may also be integrated into such a composite fagade panel (such as electrical services and mechanical services, venting structures, etc.), as might typically be found in a multi-storey building.
  • the composite fagade panel 10 is also provided with an attachment means 40, for affixing the composite fagade panel 10 to the structure of the building.
  • 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 fagade panel 10 may be installed or hung onto an upper floor, such that the fagade panel 10 extends down one or more floors of the building.
  • 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).
  • the composite fagade panel 10 is a unitary, prefabricated panel.

  • the windows 32 in the window subpanel 31 may have an irregular window pattern.
  • the present composite fagade panel system 10 is readily customizable in order to be adapted to different construction requirements and configurations.
  • 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.
  • 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 facade 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 26 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.
  • Fig. 5 illustrates another possible embodiment of the envelope structural subpanel 20.
  • the strengthening spacers 28 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).
  • a first composite fagade 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 fagade 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.
  • composite fagade panels may be installed and hung from other floor slabs, thus creating a multi-storey curtain wall for the building.
  • 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 fagade panels.
  • 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.
  • composite facade panels may also be provided with connectors or attachment means for vertically connecting composite facade panels with other composite fagade panels disposed above or below thereto.
  • composite fagade 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 fagade panels is such that they can be configured/adapted and customised for different specifications.
  • the straight composite fagade panel 10 described above may be adapted or configured for various other building features or geometries.
  • Fig. 7 illustrates a number of other types of composite fagade panels having various additional features.
  • comer facade panel 60 includes a comer section 62, which is used for constructing a portion of a curtain wall corresponding to a comer of a building.
  • Another facade panel 64 may be provided with a soffit panel 66, and used for fagade panels where a section of a building has an overhang.
  • Fagade 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 a balcony/parapet is required.
  • fagade panel examples will each potentially have the same sort of advantages discussed previously that are applicable to the straight composite fagade 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.
  • a composite fagade 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 fagade panel.
  • 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.

  • Such interlocking fagade 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 fagade panel expands in the vertical direction, there is generally sufficient “play” within the gap between the tongue and groove joint to permit such expansion.
  • a composite fagade panel may also be actually attached and secured to another vertically adjacent fagade 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 fagade panel 16 is engaged with and attached to a second fagade panel 14, such that it does not need to be secured in quite the same fashion to a third floor slab 56.
