PURPOSE: To reduce the amount of plywood used as a form material and to save labour required for beam construction by integrating a reinforcing steel preassembled body and a beam waste form consisting of a deck plate with each other through a temporary reinforcing steel truss body supporting the reinforcing steel preassembled body consisting of beam constituting reinforcing steel. ;CONSTITUTION: By assembling beam constituting reinforcing steel such as a beam upper end bar 3a, a beam lower end bar 3b, a stirrup 3c and others which are beam main bars, a reinforcing steel preassembled body 3 is formed. Thereafter, to both sides of the reinforcing steel preassembled body 3, a temporary support truss body 4 is connected along the longitudinal direction of a beam. Thereafter, in an erection process of a beam waste form 2 with a deck plate as a side plate 2a and a bottom plate 2b, the reinforcing steel preassembled body 3 and the temporary support truss body 4 are hung up and connected to each other by a plural number of hoisting accessories 4a installed on the top end of the side plate 2a of the beam waste form 2. Additionally, after finishing erection of the beam waste form 2, a reinforcing steel preassembled body 1 with a formwork is formed by installing a band body. Consequently, it is possible to reduce use frequency of a crane and to eliminate support by timbering.;COPYRIGHT: (C)1993,JPO&Japio
