Description

Special-shaped steel pipe column and supporting combined shear wall Technical Field The utility model relates to the technical field of assembled buildings, in particular to a special-shaped steel pipe column and a supporting combined shear wall. Background In recent years, most of structures in China still adopt reinforced concrete columns, but researches show that under various novel reinforcement schemes, the reinforced concrete columns have improved comprehensive performance, but the comprehensive earthquake-resistant performance and the shearing damage are serious, the improvement of the connection Liang Yanxing and the shearing resistance is limited only by improving the stirrup quantity and the reinforcement form, and the construction is complex and the reinforcement configuration is denser, so that the pouring of concrete is not facilitated. The application range of the concrete-filled steel tube column is limited, the concrete-filled steel tube column is only widely applied to the bridge at present, when the wall of the steel tube is thin, steel bars or section steel still need to be arranged in the concrete-filled steel tube column, the construction is complex, and the ideal combination effect of the steel tube and the concrete cannot be achieved for the concrete-filled steel tube with the thicker wall. Meanwhile, the current combination form of the concrete filled steel tube column is single, the concrete filled steel tube column is difficult to apply when the section shape is special, and the restraint function is not fully exerted. Based on the above problems, the present invention has been developed. Disclosure of utility model (One) solving the technical problems Aiming at the defects of the prior art, the utility model provides a special-shaped steel pipe column and a supporting combined shear wall, which solve the problems in the prior art. (II) technical scheme The special-shaped steel pipe column comprises square columns and a plurality of U-shaped columns, wherein the side parts of the square columns are provided with webs used for positioning and abutting the two ends of the U-shaped columns. Preferably, the device further comprises a connecting part for installing the framework beam, the side part of the U-shaped column is provided with a connecting plate, fixing holes are formed in the connecting plate at equal intervals along the length direction of the connecting plate, and the connecting part can be fixed on the connecting plate. Preferably, the connecting portion comprises a slot, a fixed sleeve, a fixed seat and a rotating seat, the fixed sleeve is installed on the fixed hole through a fixed bolt, the fixed seat is connected with the fixed sleeve, the rotating seat is rotationally connected on the fixed seat, the slot is arranged on the rotating seat, and a positioning and locking assembly is arranged between the fixed seat and the rotating seat. Preferably, each side of the U-shaped column is provided with two connecting plates, and the fixing sleeve is in a U shape and surrounds the connecting plates.
