Background
The double-steel-plate-concrete combined wallboard structure is an important structural form in a steel-concrete combined structure, and is a structural form formed by connecting steel plates on two sides and concrete in the middle through a shear connector, so that the combined structure can exert good overall performance and strengthen the out-of-plane shear resistance. Through the mutual constraint action of the steel plates on the two sides and the built-in concrete, the whole structural body has the advantages of high bearing capacity, good ductility, excellent earthquake resistance, impact resistance, leakage resistance and the like. The method is widely applied to nuclear containment, blast wall, polar offshore structure, ship structure and other directions.
The shear connector who uses now has to wear the bolt and leads to the condition of both sides steel sheet unevenness, under the non-to-wear condition, the shear connector has the relatively poor condition of ability of shearing or tensile strength, and traditional connecting piece is because little with the steel sheet welding interface simultaneously, appears the interface easily and slides. The above disadvantages of the conventional connector may cause the shear connector and the steel plate to not work normally in cooperation, and may cause structural failure to cause great hidden trouble.
