2. Description of the Related Art Conventionally, when a column and a beam are joined on the top floor or the floor of a reinforced concrete building, the upper end of the column main reinforcing bar in the reinforced concrete column is bent into a J-shape or separately manufactured. The fixing force to concrete has been secured by fixing the U-shaped or U-shaped reinforcing bars as lap joint bars. Further, a method of improving a fixing force by attaching a fixing plate to an upper end portion of a column main reinforcing bar has also been performed.

However, in the conventional method of bending and fixing a column main reinforcing bar into a J-shape or the like,
Since the column main reinforcement more than the number of columns originally used in the beam-column joint is complicatedly arranged, there has been a problem that the work of arranging the beam main reinforcement is difficult and time-consuming.

[0004] In the method of fixing a J-shaped or U-shaped lap joint bar to a column main reinforcing bar, in the case of pre-casting of a column, when the beam main reinforcing bar is laid, the concrete of the column already has a beam. Because the lower surface of the lap joint is cast, the lap joint cannot be fixed to the concrete below the beam-column joint, so that the required length of the lap joint cannot be secured.

Therefore, in this case, a concrete projection located on the upper side of the column is provided on the top floor slab, and a lap joint is buried in the projection to secure a necessary fixing length. In this case, design restrictions are increased, and it is troublesome to provide the projections. Further, when the waterproof sheet is attached on the roof, the projections may interfere, and the waterproofing may be incomplete.

Further, in the method of attaching the fixing plate to the column main reinforcing bar, although the fixing force in the tensile direction of the column main reinforcing bar is improved, when a large pull-out force acts on the column main reinforcing bar,
As explained next, there was a risk that the concrete around the column main reinforcement would be damaged.In other words, when a large pulling force acts on the column main reinforcement, a large bearing pressure occurs between the fixing plate and the concrete. Because the bearing capacity of the concrete outside is weaker than the bearing capacity of the concrete inside the column, the bearing plate generated between the fixing plate and the concrete extrudes the fixing plate to the outside where the bearing capacity is lower. The concrete is destroyed.

Further, by improving the anchoring force of the column main reinforcing bar 11, the upper end of the column main reinforcing bar 11 is bent into a J shape or a J-shaped or U-shaped joint bar is attached as in the conventional case. Since there is no necessity, the reinforcement arrangement structure of the beam-column joint is simplified, and the arrangement work of the reinforcement of the beam main reinforcing bar 12 is facilitated. In addition, even when the column 1 is previously driven, the column main reinforcing bar 11
Fixing power can be secured.
