REINFORCED CONSTRUCTION FOR JOINT PART OF REINFORCED CONCRETE PILLAR AND STEEL FRAMED BEAM

摘要

PURPOSE: To prevent local bearing breakage by respectively arranging reinforcing iron plates on the lower face of an upper story pillar and the upper face of a lower story pillar which are in contact with the upper and lower flange faces of a steel framed beam in the joining part of pillar and beam. ;CONSTITUTION: The joining part of pillar and beam B' of a steel framed beam B is provided on the reinforcing iron plate 2 of the precast RC pillar A of a lower story, a formwork is assembled by surrounding the joining part B' with hoop reinforcement 5, and concrete of the joining part B' is placed together with slab concrete. Next, the precast RC pillar A₁ of an upper story is built on, a reinforcing iron plate 1 is integratedly fitted to the lower face, the pillar main reinforcement 3 of the pillar A₂ is inserted into a splice sleeve 4 and mortar is filled, and hence the main reinforcement 3 of the pillars A₁, A₂ of the upper and lower stories are connected together. Against the force applied on the joining part B', the average force is transmitted from the beam B to the pillars A₁, A₂ through the iron plates 1, 2. Hereby, local bearing breakage at the pillars A₁, A₂ can be prevented.;COPYRIGHT: (C)1993,JPO&Japio
