Abstract: A gravity type debris chute formed by hanging a plurality of corner panels on corners of a structure having horizontal elements, a plurality of side panels and a door panel on the structure with horizontal structural elements so as to form a passage for debris to pass through, wherein each of the said corner panels is folded in the middle so as to form two symmetrical sides, the top of each of said corner panels folded to form a lip or a u fold so as to hang from a structural member, each of said side panels folded at the top to form a u fold or a lip capable of hanging from a horizontal structural member.

Abstract: A method of constructing a suspended floor is described in which a plurality of beam-forming formwork assemblies are located in substantially parallel alignment, the beam-forming formwork assemblies are supported in support assemblies on a support base in stable equilibrium, a plurality of floor-forming formwork assemblies are located between the beam-forming formwork assemblies for support thereon, concrete is poured in said formwork assemblies, the concrete is allowed to set, and the formwork assemblies are removed from the set concrete for re-use.
