That is to say, the end of the connecting piece can not be protruded outside the steel plate main body, or only a smaller part of the end of the connecting piece is protruded outside the steel plate main body, thereby ensuring that the outside of the steel plate main body has no protruding structure or has no larger protruding structure. Therefore, the concave steel plate concrete composite wall provided by the embodiment of the application can effectively reduce the difficulty of coating the filling material on the outer side of the steel plate main body, and can form a smooth wall surface more easily.
Moreover, the steel plate main body in the concave steel plate concrete combined wall provided by the embodiment of the application can be flat steel, the concave part can also be set to be a structure with a smaller size, and compared with the profiling process of a corrugated plate, the stamping process of the steel plate main body improves the manufacturing efficiency and reduces the manufacturing cost; in addition, the steel sheet main part of this application compares with the wave plate of equal effective width, and the steel quantity of the steel sheet main part of this application is littleer, can reduce material cost, improves steel availability factor.
