Abstract:
1. A polycarbonate building panel for the construction industry, the panel comprising: a hollow elongate structure having a generally rectangular cross-sectional profile, the elongate structure comprising a first upper outer skin and a second substantially planar lower outer skin joined by first and second side walls; a connection device provided on each side wall respectively wherein, in use, adjacent panels can be connected to each other side by side with the connection devices to form a segment of a wall or roof, wherein the connection devices each comprise a first rib and a second rib, the first rib being adapted to engage with a matching rib on an adjacent panel and the second rib also being adapted to engage with a matching rib on the adjacent panel, and wherein the second rib on each side wall has a rectangular profile with a lower wall and an outer wall forming an upwardly open channel, the second rib on the first side wall being formed with a recess immediately adjacent thereto between the channel and the hollow elongate structure, the recess being downwardly open and adapted to receive an outer wall of the second rib on the second side wall of an adjacent panel therein so that the channel of the second rib on the first side wall of an adjacent panel is received in a nested arrangement within the channel of the second rib on the second side wall of the panel to provide an interlocking relationship, and wherein the lower wall of the second rib on the second side wall is substantially aligned with the lower outer skin of the elongate structure so as to form a substantially seamless planar lower surface of the panel when adjacent panels are connected; and, an elongate locking member is provided to lock the first and second ribs into engagement with the matching ribs on an adjacent panel wherein, in use, adjacent panels are locked together to form a segment of a wall or roof.
