Fixation end reinforcement device null of beam

摘要

PURPOSE: To increase the fixing force of a beam main reinforcement by fish-joint fixing a fixing-reinforcing steel plate having an arc-shape being the same in curvature as the bore of the fixing end bent part of the beam main reinforcement to each fixing end bent part of the beam main reinforcement for one step. ;CONSTITUTION: A fixing-reinforcing steel plate 4 having the same curvature as the bore of a fixing end bent part 2 of a beam main reinforcement 1 is formed, and attaching holes are drilledly provided at fixed intervals in the longitudinal direction of the steel plate 4. The steel plate 4 is fish-jointed to the inner periphery of each fixing end bent part 2 of the beam main reinforcement 1 for one step, and fixed to each beam main reinforcement 1 with a stranded wire 6 inserted through the attaching hole. Thus, when earthquake force makes drawing out force act on the beam main reinforcement 1, the drawing out force is transmitted to the steel plate 4 as compressive force, and concentrated force therefore does not act on concrete, and the local fracture of the concrete can be prevented.;COPYRIGHT: (C)1993,JPO&Japio
