Abstract
A frame unit (11) used in the construction of a formwork module. The frame unit (11) is formed by connecting together rectangular loops of wire (12, 13) to form a rectangular block shape. Panels (60) and reinforcement (16) are connected to the frame to make a formwork module, with the reinforcement (16) extending beyond the sides of both the frame unit (11) and the panels (60). When a number of modules are connected together to form formwork for the desired building structure, the reinforcement (16) overlaps to form a continuous line of reinforcement from one module to the next.
Claims12
A module for use in constructing a formwork, said module comprising:
- (a) first and second wall sections, each wall section having substantially rectangular major surfaces and peripheral flanges extending from the edges of one of the major surfaces;
- (b) a plurality of openings in the major surfaces of the wall sections;
- (c) a plurality of rigid elongate members extending between the wall sections to secure the wall sections to each other;
- (d) removable fastening means for temporarily fixing the first and second wall sections with respect to the rigid elongate members at a predetermined spacing;
- (e) reinforcing rod securement means attached to the rigid elongate members allowing vertical and horizontal reinforcing members to be secured relative to the wall sections upon assembly of the modules;
- and
- (f) means for temporarily and directly securing the peripheral flanges of adjacent modules of the wall sections to form a formwork for a concrete wall which upon curing of the concrete, and upon release of the fastening means allows the wall sections to be simultaneously stripped from the concrete wall.
