초록 ▼

A space truss is constructed of a pair of plane trusses. Each of the plane trusses is constructed of an upper and lower chord member fixedly connected with each other through a strut member interposed therebetween. The thus constructed plane trusses are oppositely disposed from each other in a condition in which the strut member of each of the plane trusses are interposed between the thus oppositely disposed plane trusses, the upper chord members of the plane trusses are closely disposed together, and the lower chord members of the plane trusses are spaced apart from each other. A sheet steel is fixedly connected to the space truss through a hanging hook to form a composite-type space truss. Any of these space trusses are embedded in concrete in the factory to form a precast reinforced concrerte slab.

A space truss comprising a pair of plane trusses oppositely disposed from each other, each of said plane trusses being constructed of a pair of chord members comprising an upper chord member and a lower chord member both of which are fixedly connected to a strut member, said upper chord members of said plane trusses being arranged parallel to each other, spaced apart by said strut members being interposed between said upper chord members of said plane trusses and attached by weldments fixing upper portions of said strut members together, said lower chord members of each of said plane trusses being spaced apart a distance greater than a distance between said upper chord members, a sheet steel, which provides a formwork for receiving poured concrete disposed under said lower chord members of said space truss, a hanging hook welded to said sheet steel interposed between said lower chord members and said sheet steel, and said hanging hook has at least one hook portion through which said hanging hook engages said lower chord members of said space truss to permit said lower chord members of said space truss to move vertically a predetermined distance relative to said hanging hook.
