【産業上の利用分野】鋼管コンクリ−ト柱と梁の仕口構

いられていた。2. Description of the Related Art Steel pipe concrete columns are expected to have high yield strength and high rigidity and are also excellent in deformability. Therefore, they are attracting attention as future structural members. However, regarding the joints between steel pipe concrete columns and beams,
In addition to the through-diaphragm, inner-diaphragm, and outer-diaphragm types, a long tightening bolt system using a split T has been used.

かった。However, the through-diaphragm and the inner-diaphragm have poor filling properties of concrete, while the outer-diaphragm type having no projections on the inside has a drawback of causing interference with the finishing material. In addition, the long-tightening bolt system has good filling properties of concrete, and exhibits excellent structural properties in which the stress of the beam flows directly to the beam on the opposite side of the column.
However, with the conventional long-tightening bolt method, if the bolt is fully tightened before casting concrete on the steel pipe column, the steel pipe column will be deformed concavely, which is not preferable. It is. In the case of a prism, the steel tube column tends to bulge in a circular shape due to the lateral pressure of the concrete. In addition, the axial force introduced to the bolt will decrease in the long term due to the creep of concrete in the steel column. For this reason, the degree of fixation of the joint is reduced. In addition, when the beam comes into contact with the steel pipe column, the long fastening bolt is inserted in a state where the beam is set, so that the beam is unstable, and there are many disadvantages such as difficulty in construction.
【０００４】本発明はこれらの問題点を解決するように
工夫されたものである。The present invention has been devised to solve these problems.

筋を配置しておく。しかしリング筋はなくてもよい。A ring stiffener is welded to a portion of a steel pipe column to which a beam is to be joined, and a beam to which an end plate is welded in advance is temporarily placed on the ring stiffener. A high-strength large-diameter threaded reinforcing bar is inserted into the end plate of the beam and the steel pipe column, and a filling screw fixing plate is attached to both sides of the steel pipe column.
Check that the filling screw fixing plate is in the predetermined position,
Inject the binder into the filling screw fixing plate. After that, concrete is cast on the steel pipe columns and floor concrete is cast.
At this time, a ring bar is preferably arranged on the slab for restraining the steel pipe column. However, there is no need for the ring streaks.

In the structure of the present invention, the degree of fixation is ensured by the tension up to the separation load between the column and the beam. The long fastening bolt method that has been used conventionally secures the degree of fixation by the tension of the bolt, but in the present invention, the adhesive force to the reinforcing bar is used.

とにより、問題は解消する。According to the effects of the present invention, it is possible to provide a bolted structure which is less affected by the creep of concrete of a steel pipe concrete column. Conventionally, when a beam is in contact with a steel tube column, the large diameter threaded rebar is set with the beam set, so the beam is unstable and construction is difficult. However, providing a ring stiffener solves the problem.
