Collapsible form reinforced structure for floors or multi-story buildings

Abstract

The present invention relates to a structural element and more particularly to prefabricated T-beams which are designed to be manufactured in different dimensions and which are capable of supporting high loads. It is an object of the invention to provide such structural elements of great strength and which can be manufactured in dimensions necessitated by individual requirements with relatively overall low labor and material costs. According to the invention there is provided a prefabricated metal form characterized by the fact that it is disposed to form an arch shape between parallel support T-beams underneath the concrete flooring during the curing phase of the concrete construction, which is designed to take up the tension and stress of the above flooring, said form elements disposed in parallel in relation to one another.

1 . A collapsible form reinforced structure for floors or multi-story buildings having a plurality of spaced beam structures each consisting of an elongated concrete slab, a plurality of spaced longitudal bars embedded in said slab, an upper longitudal bar spaced upwardly from said slab, and a plurality of groups of reinforcement bars of pyramidal configuration mounted on said slab with their apices joined to the upper longitudinal bar, wherein the improvement comprises: 
 a. a collapsible metal form interposed between said slabs in an upwardly arch shape with the lower ends of said form joining said slabs; and    b. a wooden cleat to be inserted in said form for purpose of increasing the strength of the intersection of said slab and said form.
