Abstract
Abstract A building element suitable for floors, walls, or roofs, has oppositely disposed U-shaped channels at either end of the element. Adjacent building elements can be overlapped so that their complementary channel members are interengaged to form a box section member to reinforce the completed cladding and also provide for the insertion of timber blocks or studs. The cladding can be fastened to a building structure by fasteners passing through the box section and through the spacer blocks of timber or other material.

A building structure comprising: two or more sheet building elements, each of said elements including a sheet of substantially rigid material having complementary interlocking means at or adjacent a pair of lateral edges thereof, a first of said interlocking means consisting of a substantially rectangular open topped trough having a flat base, and a second of said interlocking means consisting of an inverted substantially rectangular trough having a flat top and an open base, and clip means formed in said complementary means, whereby adjacent sheet building elements are conjoined by overlapping their adjacent edges so that a first and a second interlocking means are combined to form a substantially weather tight hollow substantially rectangular box section member to which linings or strappings can be attached by fasteners without damaging the weather tightness or integrity of the profile; and timber elements provided within said hollow substantially rectangular box section to pass through either of said sheet building elements into said timber elements for connection with a supporting framework.
