MULTI-COMPONENT FORM SYSTEM

A prefabricated collapsible formwork module is assembled at a factory site, including the provision of a pair of sheathing panels (1,2) which can be made of insulating material, as well as the mounting of the vapor barrier (13), the filler strips (9), bearing blocks (4,5), and flexible or foldable connecting elements (3) extending between bearing blocks on the exterior surfaces of the panels extending between the panels to retain the panels when they are being erected. The sheathing panels may also have a waterproof membrane applied thereto, and the concrete reinforcement is assembled between the sheathing panels at the factory site. When the framework module is fully assembled, it is then collapsed, that is, by moving one sheathing panel against the other including sandwiching the foldable or flexible connecting elements and the concrete reinforcement which is preferably in the form of a grid, and the module can then be stored and transported to a building site. At the building site, the module is spread apart to the full extent of the connecting means and spacers are provided between the sheathing panels for maintaining the panels apart. Typical male (14) and female (13) plates are intercalated at the edges of the sheathing panels to form joints (24) with adjacent panels.
