Background
The stiffening concrete composite structural member is adopted in a high-rise or large-span structure, and the structural steel is added in the original reinforced concrete beam, column and other members, so that the bearing capacity of the members is improved, and the axial compression ratio of the members is reduced. However, after the section steel columns are added at the beam column joints, the construction of the beam main reinforcements becomes difficult due to limited space.
To solve the above problems, there are two conventional methods. The first method is to weld a ring plate around the section steel column, and the beam main reinforcement is welded with the ring plate. However, when the main beam ribs are designed into multiple rows, the space between the ring plates is narrow, the welding difficulty is high, and the concrete in the area is difficult to vibrate and compact. And the second method is to weld the connectors at the positions of the side walls of the section steel columns corresponding to the main beam ribs. The method has higher requirement on welding precision and large difficulty in actual field operation.
