Connecting structure of stiff tubular column and reinforced concrete beam column

Abstract

The invention relates to the field of building construction, in particular to a connecting structure of a stiff tubular column and a reinforced concrete beam column. The connecting structure comprises a tubular column, a steel corbel fixed on the tubular column and reinforcing steel bars fixed on the tubular column, and further comprises a lap joint piece, the lap joint piece is welded and fixed on the steel corbel, a welding plane parallel to the axis of a reinforcing steel bar is arranged on the lap joint piece. The reinforcing steel bars are welded and fixed to the welding plane. In the connecting structure of the stiff tubular column and the reinforced concrete beam column, the steel corbel is connected with the peripheral reinforced concrete beam column in the form of the lap joint piece, so that the steel corbel is safe, reliable, reasonable and orderly, the perforation of the tubular column is avoided, and the construction inconvenience and the potential quality hazard caused by welding by adopting connectors on a large scale are also avoided.

Description

technical field [0001] The present application relates to the field of building construction, in particular to a connection structure between a rigid circular pipe column and a reinforced concrete beam column. Background technique [0002] Stiff concrete structure is a main form of steel-concrete composite structure, which is a special composite material formed by adding section steel inside reinforced concrete. Since the shaped steel core exists like a skeleton, it can effectively improve the ductility of the concrete and greatly improve the seismic performance of the concrete; and the lateral restraint of the concrete on the steel ensures that the mechanical properties of the steel can be exerted and will not quit work due to instability. The circular tube column has been more and more used in long-span structures, high-rise buildings and super high-rise buildings in earthquake zones because of its better bearing capacity, stiffness and seismic resistance than steel struct...

AI Technical Summary

Problems solved by technology

Using the above two connection methods, there are many construction problems in the connection between the rigid circular pipe column and the surrounding reinforced concrete beam-column: if the steel bar passes through the cylindrical column body, the stiffness of the circular pipe column itself will be weakened, and the rigidity of the circular pipe column itself will be weakened. It is difficult to accurately reserve the position of the hole; if a large-scale use of steel bar connectors is used to weld the round pipe column, there will be no space for welding, and the welding quality will be difficult to guarantee
