Description
“BUILDING PANEL”
The present invention relates to a building panel and a building system and relates particularly, though not exclusively, to a polycarbonate roofing or wall panel.
Polycarbonate roofing panels are well known in the building and construction arts. They are relatively lightweight, strong and translucent, providing a passive form of solar heating and lighting. They are used in domestic, industrial and commercial building applications. Prior art polycarbonate roofing panels are supplied in varying thicknesses up to 30mm, and up to 6m in length. For some specialised applications they can be purchased up to 12m in length. However all prior art polycarbonate sheeting requires additional steelwork for support, and this introduces undesirable aesthetic constraints from an architectural and design perspective.
The present invention was developed with a view to providing a building panel and system which fills a gap in the building and construction industry, namely, a cost-effective polycarbonate system with long span capability. However it will be apparent that the building panels can also be manufactured from suitable materials other than polycarbonate.

Figure 6 is side elevation of a preferred embodiment of an end cap for the building panel of Figure 1.
A first preferred embodiment of the building panel 10 as shown in Figures 1 to 4 comprises a hollow elongate structure 12 having a generally rectangular cross-sectional profile as can be seen most clearly in Figure 1. The elongate structure 12 comprises first and second outer skins 14a and 14b joined by substantially parallel first and second side walls 16a and 16b. The outer skins 14 of the elongate structure 12 preferably have a degree of outward curvature in profile so as to form convex outer surfaces. The convex outer surfaces advantageously give the panel 10 a self-cleaning capability wherein dust and other contaminants simply run-off the outer convex surfaces when wetted.
The building panel is preferably made of polycarbonate.
The panel 10 further comprises a connecting means 18 provided on each side wall 16 respectively wherein, in use, adjacent panels 10 can be connected to each other side by side with the connecting means 18 to form a segment of a wall or roof, as shown in Figure 4. The panels 10 are primarily - designed for use as roofing panels, however in view of their structural strength and rigidity it will be understood that they can also be used in a variety of other ways for constructing a building, including wall panels.
Preferably the elongate structure 12 comprises a third inner skin in the form of a web 20 extending between the first and second side walls 16 so as to divide the interior of the elongate structure into two chambers. The dual chamber profile of the elongate structure 12 provides the panel 10 with additional structural strength and rigidity, as well as improved thermal and sound insulation properties.
Preferably the connecting means 18 each comprise a first rib 22a and a second rib 22b. The first rib 22a is adapted to engage with a matching rib 22a on an adjacent panel, and the second rib 22b is also adapted to engage with a matching rib 22b on the adjacent panel (see Figure 2). In this embodiment the first and second ribs 22 each have a curved profile and are arranged with concave surfaces facing each other. In the present case the ribs 22 have a semicircular profile, however it will be understood that a variety of profiles would work.
As can be seen most clearly in Figure 1, the ribs 22 together with the side wall 16 form a cavity. Preferably the matching ribs 22a and 22b on an adjacent panel have a matching curvature and are received in a nested , engagement with the respective first and second ribs 22a and 22b when adjacent panels are connected to each other side by side with the connecting means (see Figure 2). The inside diameter of the first rib 22a is approximately equal to the outer diameter of the matching rib 22a, and the outside diameter of the rib 22b is approximately equal to the inside diameter of the matching rib 22b, in order to facilitate their nested engagement. Advantageously the nested engagement of the ribs 22 together with the respective side walls 16 of the adjacent panels 10 form an enclosed cavity 24 between the adjacent panels.
Preferably an elongate locking member 26 is received in the enclosed cavity 24 to lock the ribs 22 into nested engagement with each other. In this manner adjacent panels 10 are locked together to form a segment of a wall or roof.
One of the purposes of the locking bars 26 is to absorb upwardly directed wind pressure. Figure 4 illustrates a roof segment of a wall segment 30 formed from a plurality of the panels 10 connected to each other side by side with the connecting means 18. Two types of locking member 26 are provided (see also Figure 5). A first locking member 26a is made from extruded aluminium and gives the roof segment increased strength and rigidity. A second locking member 26b is made from extruded polycarbonate. Both locking members 26 are typically inserted manually during the assembly process. Preferably the ribs 22 are sealed in their nested engagement using a butyl rubber mastic sealant.
In one form of the panel 10 the elongate structure 12 is substantially planar.
In another form of the panel 10 (not illustrated) the elongate structure 12 is formed with a degree of longitudinal curvature to give the panel increased load-bearing capacity. The locking members 26 may likewise be curved so as to be received in the enclosed cavities 24 between the panels. The panels 10 can be pre-curved during the manufacturing process. When the panels 10 have been assembled they are placed on a bending table which slides directly into the oven for a specified time period. The angle of curvature of the bending table is preset to correspond to the desired shape of the roof. After this process the panels are left to cool and on larger spans curved aluminium locking bars 26 are inserted. This then forms the specified curvature of the panels. The completed panels can then be delivered to site. Installation of the panels is identical to flat applications; polycarbonate locking bars 26 are inserted, which simply lock the panels together.
A typical roof bay comprises six of the panels 10 connected side by side (two of the roof segments 30 of Figure 4 connected side by side). Various combinations of locking members 26a and 26b may be employed to attain different structural strength capabilities for the roof bay. The loading combinations are as follows:

The Locking System weight and dead load specifications are as follows:
LS1 weight = 7kg/sqm. Dead load 0.078kN/sqm.
LS2.1 weight = 9kg/sqm. Dead load 0.091kN/sqm.
LS2.2 weight = 10kg/sgm. Dead load 0.101kN/sqm.
LS2.5 weight = 14kg/sqm. Dead load 0.142kN/sgm.-
Advantageously the hollow elongate structure 12 is manufactured from extruded polycarbonate. Preferably the outer skins 14 and side walls 16 of the elongate structure 12 are between 1mm to 2.5mm thick. Preferably the upper outer skin 14a is slightly thicker than the lower outer skin 14b. Typically the upper outer skin 14a is between 1.2mm to 2.0mm thick. Typically the lower outer skin 14b is between 1.4mm to 1.8mm thick. Preferably the upper outer skin 14a has a UV resistant layer applied to it. Typically the UV resistant layer has a minimum thickness of 0.050mm.
Preferably the total thickness of the polycarbonate panel 10 is between 65mm to 90mm. More typically the total thickness of the polycarbonate panel 10 is between 73mm to 76mm. A preferred embodiment of the polycarbonate panel 10 is about 74mm thick. Preferably the total width of the polycarbonate panel : 10 is between 80mm to 120mm. More typically the total width of the polycarbonate panel 10 is between 95mm to 110mm. A preferred embodiment of the polycarbonate panel 10 is about 100mm wide.
Preferably the building panel 10 further comprises an end cap 40 adapted to be received in the hollow end of the elongate structure 12. Advantageously the end cap 40 has first and second spigot pieces 42a and 42b adapted to be received in the two chambers of the hollow elongate structure 12. As can be seen most clearly in Figure 6, the end cap 40 has a planar front face 44, on the back of which the spigot pieces 42 are formed. The first spigot piece 42a opens onto the front face 44, and forms a handhold which can be grasped to insert the end cap 40 into the end of the hollow elongate structure 12 (see
Figure 5).
