The other is an externally-straightened anchor connecting structure of the horizontal steel bars of the superimposed shear wall, and the corresponding defects are that (1) the exposed horizontal steel bars of the straight anchors are too long, the transportation and the assembly are inconvenient, (2) the binding of the steel bars of the edge members are more, and the construction is more complicated. The technical proposal that the steel bars extending outwards from the side surfaces are anchored on post-cast concrete of the vertical joints; when producing prefabricated members with overhanging steel bars, slotting and perforating are needed, the steel bars are difficult to install, the template is large in spreading, the production efficiency is low, the overhanging steel bars are easy to collide and bend in the transportation and hoisting stages, and the straightening process is increased; in the prefabricated member installation stage, the overhanging steel bars of adjacent components mutually interfere, the installation of the post-added steel bars is difficult, and the construction efficiency is low.

However, this technique is complicated in structure and difficult to implement.
The existing other overlapped shear wall closely spliced vertical joint structure and construction method is characterized in that the capacity of the vertical joint mold for resisting the pressure of a post-pouring concrete pouring side mold in a cavity is utilized; but the distance between the outermost steel bar truss and the side edge of the prefabricated wall is enlarged to more than 450mm, so that the stress performance of the shear wall is reduced, the rigidity of the concrete wallboard outside the outermost steel bar truss in the transportation and installation stages is small, and the concrete wallboard is easy to damage.
The matters in the background section are only those known to the public inventor and do not, of course, represent prior art in the field.
