Disclosed is a prefabricated concrete formwork module that may be assembled with others similar modules in the manner of a brick wall to form a mold into which concrete is poured. The formwork module has a reinforcing structure preferably made of parallel grids connected by transverse tie-rods. It also has a pair of opposite panels forming spaced apart longitudinal side-walls. It further has arms defining a bridge for providing stability between adjacent modules when assembled to form a wall. Preferably, the panels are made of an insulating material.

[ I claim:] [1.] A formwork module for forming a concrete wall, said module comprising:a reinforcing structure comprising:at least three metal grids extending in parallel vertical relationship, said grids being spaced apart from each other with two of said grids extending externally, every other one of said grids extending inwardly between said externally extending grids; anda plurality of tie-rods extending transversely to said grids; said grids and tie-rods being rigidly connected to each other and altogether forming a unitary structure;a pair of opposite panels extending in parallel vertical planes, each of said opposite panels embodying one of said two externally extending grids and forming therewith a longitudinal side-wall, said side walls being spaced apart and facing each other in parallel relationship; andbridging means connected to said reinforcing structure and projecting upwardly above said panels, said bridging means co-operating with the reinforcing structure of a similar module stacked upon the said module for providing stability between said modules when assembled to form a wall.
