Further, the steel core concrete column includes concrete column and the steel pipe for being set in concrete column periphery.
Further, described shear connector one end is connect with steel mesh, and the other end is connect with steel pipe.
Further, the shear connector includes the steel plate to connect steel mesh and steel pipe, is equipped on the steel plate
Perpendicular to the reinforcing rod of steel plate.
Compared with prior art, the utility model has the beneficial effects that the utility model passes through in concrete filled steel tube periphery
Ultra-high performance concrete layer is set, high intensity that ultra-high performance concrete has, high solidity, high-durability can be mixed with steel pipe
The performance that the bearing capacity that solidifying soil has is high, rigidity is strong combines, and overall structure is made to have bearing capacity high, good, durable from heavy and light, ductility
The advantages that performance and good anti-seismic performance, while the utility model structure is simple, design is rationally, easy for construction, can be applied to China
The bridge pier structure of western China earthquake prone areas, improves service life and reduces maintenance cost.
To can be more clearly understood the above objects, features, and advantages of the utility model, with reference to the accompanying drawing to this
The specific embodiment of utility model elaborates.
