Reinforcing bars must be arranged in steel pipes. In addition, in order to embed the reinforcing bars almost uniformly in the circular cross section of the concrete-filled steel pipe structure, the work becomes complicated because the main reinforcing bars of the beams of the reinforced concrete structure intersect with the reinforcing bars.

Decrease. Shaped steels include angle irons, channel steels, I-shaped steels, H-shaped steels and deformed steels. A reinforcing bar or a steel bar extending from a steel bar or a steel reinforced concrete structure is fixed to a concrete-filled steel pipe structure with concrete. In response to the bending moment acting on the corner joint, the reinforcing steel and the steel frame fixed in the steel pipe column with concrete transmit stress as a bearing force and a frictional force to the column steel pipe. As a result, the corner joint between the concrete-filled steel pipe structure and the reinforcing steel and steel-framed reinforced concrete structures is
It can be joined so as to have sufficient strength and rigidity.

As a result, the corner joint between the concrete-filled steel pipe structure and the reinforcing steel or the steel reinforced concrete structure is joined. This corner joint between the reinforcing steel or steel-framed reinforced concrete structure and the concrete-filled steel pipe structure has high strength and high rigidity, that is, high deformation performance due to the shape steel being arranged as the steel frame. Therefore, the load applied to the reinforcing bar or the steel reinforced concrete structure can be preferably transmitted to the concrete-filled steel pipe structure.

Even when the steel frame was arranged at the corner joint of the present invention and the number of reinforcing bars for the joint was reduced, both the yield strength and the ultimate strength exceeded those of the prior art. This is because, by reducing the number of reinforcing bars of the reinforcing steel and the steel-framed reinforced concrete structure of the present invention and the reinforcing steel bars for the concrete-filled steel pipe structure, the reinforcing bar reinforcing work at the dense and complicated joint portion is reduced. Simplified. In addition, the arrangement of the steel frame at the corner joint makes the proof strength of the corner joint, that is, the yield strength and ultimate strength equal to or more than that of the conventional technology, and the load of the reinforcing steel and the steel reinforced concrete structure is reduced to the concrete filled steel pipe structure as designed.
