Web member for concrete form walls

Abstract

The invention provides a building component comprising first and second high density foam panels each having inner and outer surfaces, top and bottom, and first and second ends, the panels arranged in spaced parallel relationship with their inner surfaces facing each other, and at least two bridging members extending between and through and molded into the panel members. Each bridging member comprises a pair of elongated end plates oriented vertically and abutting against the outer surfaces of the panels; a thin narrow strip member joining the mid-areas of the end plates; a series of first narrow bracing members extending from positions adjacent a mid-point of the narrow strip member to positions spaced a short distance from the ends of the end plates; and a series of second narrow bracing members extending from positions on the first bracing members to positions on the strip member intermediate the plates and the mid-point of the strip member.

Description

[0001]This application relates to a building component of the type which is used to build up permanent concrete form walls in building construction.BACKGROUND OF THE INVENTION[0002]In conventional construction in North America concrete walls are normally produced by constructing form walls, pouring concrete into the space between the form walls and, upon the setting of the concrete, removing the form walls. Finishing materials are then added to the concrete walls as required.[0003]Typically in residential construction, concrete basement and other concrete walls will be constructed in the manner discussed above and wood framing will be constructed as required on top of or beside the walls. Insulation will be inserted between the framing members and the wall finished inside and out as desired.[0004]Clearly both parts of this construction are inefficient. It is time-consuming and wasteful of materials to have to remove the form walls after the concrete walls are poured. Furthermore, it...

AI Technical Summary

Benefits of technology

[0017]It has now been discovered that substantial advantages can be obtained where the building component used to build up a concrete form wall comprises bridging members which are engineered to combine an enhanced strengthening and reinforcing grid with a substantial reduction in material. The grid achieves enhanced strength not only from the arrangement of bracing members but also from enlarged openings in the grid allowing improved flow of foam and, subsequently, of concrete.

Problems solved by technology

The components described in that patent include cross members, the ends of which are disadvantageously completely embedded in the foam blocks.
