PROBLEM TO BE SOLVED: To provide a space truss with a concrete extra form for civil engineering used in the case of construction such as a bridge floor in which the reinforcement machining and reinforcement arrangement of the bridge floor on a field are omitted and the assembly and disassembly removal operation of a bridge- floor form can be eliminated approximately.;SOLUTION: The space truss with the concrete extra form is composed of three-dimensional welding reinforcement 1 formed by combining vertical reinforcements 11, horizontal reinforcements 12 and wave reinforcements 13 and a reinforced concrete slab 2 in which concrete is placed in the lower section of the three-dimensional welding reinforcement 1 and formed in specified size. The three-dimensional welding reinforcement 1 in which the vertical reinforcements 11 of the three-dimensional welding reinforcement 1 are projected from the concrete slab 2 and connecting sections 3 are formed may be manufactured.;COPYRIGHT: (C)2000,JPO
