部材コスト建方コストが増大する。However, in the case where the main bar at the lower end of the beam is fed and bent and fixed, the lower bar of the beam overlaps, so that the beam width needs to be increased due to the restrictions on the covering of the reinforcing bar and the design. . In addition, there is no freedom in how to construct the beams in the X and Y directions, and the construction plan is restricted. Further, since the beam width is increased, the member cost and the construction cost are increased.

もにコンクリートを打設して構成されている。SUMMARY OF THE INVENTION In order to achieve the above object, a precast reinforced concrete beam-column joining apparatus according to the present invention is constructed such that concrete is poured into the lower part of a beam, and a column main bar and a vertical bar for joining an upper story column member. The precast reinforced concrete beams at the front, rear, left and right are mounted on the capitals of precast reinforced concrete columns with built-in hoops and auxiliary bars protruding from the capital, and project horizontally so that the lower ends of the beams do not overlap each other. Bending the end into the panel zone, arranging a hoop reinforcement at a bending portion of each beam lower reinforcement, and arranging an auxiliary hoop reinforcement at a bending lower portion of the beam lower reinforcement of the adjacent beam, Concrete is cast together with the slab in the panel zone.

A compressive strut of concrete is formed obliquely upward from the starting point of the bending up, and at the end of the compressive strut, the horizontal component and the vertical component are balanced by an auxiliary hoop bar having the same amount as the lower end bar of the beam and a vertical bar. The auxiliary muscles will resist.

Each of the beams 5 has a built-in rib, and the end protrusions of the lower beam 6 are fitted into the panel zone without overlapping each other, and the end of the protrusion of the lower beam 6 at the center is bent up. The auxiliary hoop bar 7 is dropped from above into the portion 6a, and then the auxiliary hoop bar 7a is dropped from above into the bent-up portions 6b, 6b of the beam lower bar of the adjacent precast reinforced concrete beam 5, and then the beam upper bar 8 And cast concrete together with the slab in the panel zone to integrate the precast reinforced concrete beams 1 and 5.
