Abstract: A set of extruded panels is provided for constructing a form-work for concrete. The set includes a plurality of first, second and connecting wall panels. The first wall panels are arranged edge to edge to form a first wall. The second wall panels are arranged edge to edge to form a second wall generally parallel to the first wall. The connecting wall panels are arranged to span transversely between the first and second walls. Each first wall panel incorporates an outer wall extending between first and second edges of the first wall panel, and an inner wall extending between first and second edges of the first wall panel, the inner wall spaced transversely from the outer wall and located relatively more proximate to the second wall panel. Each first wall panel incorporates a plurality of support walls extending transversely between the outer and inner walls.

Abstract: A set of extruded panels is provided which can be assembled on site to create a permanent form-work for concrete. The set includes inside and outside extruded side wall panels which are arranged to be connected edge to edge to form inside and outside walls. Longitudinally spaced connecting wall panels span between the inside and outside walls at spaced positions across the width of the walls to hold the walls apart and define a hollow interior therebetween including a plurality of interconnected cells with a plurality of holes for communication of concrete and reinforcing bars between each cell and the next. Each connecting wall panel has T-shaped connectors at each edge for attachment to corresponding C-shaped receptacles on the side wall panels. Rigid foam insulation is inserted at the outside wall.
