wherein, the process that inside wall element and floor were connected to wall element resistance to plucking piece is: arranging anti-pulling pieces of the wall element at four corners of an internal wall element light steel keel framework, wherein the anti-pulling pieces of the wall element are positioned at the inner sides of U-shaped light steel keel beams, connecting one side of each anti-pulling piece of the wall element with a web plate of the U-shaped light steel keel beams and a floor plate into a whole through bolts, and then fixedly connecting the other side of each anti-pulling piece of the wall element with a web plate of a C-shaped light steel keel column through bolts;
wherein, the process of the pull rod drawknot steel tube concrete column is as follows: the intermediate lever of pull rod passes the preformed hole on the C type light gauge steel post of middle part wall unit and the preformed hole on the U type light gauge steel joist roof beam, the intermediate lever of pull rod is located the light gauge steel skeleton, and at the both ends installation fastener of intermediate lever, the fastener is located the handing-over department of tip wall unit and inside wall unit, then pass the tip pole of pull rod the preformed hole on the C type light gauge steel post of tip wall unit, the tip pole is located the light gauge steel skeleton, twist the fastener with pull rod tip pole one end, the other end passes through the bolt and links into whole with the steel core concrete column, two pull rods are cross arrangement.
2. The composite shear wall capable of rapidly recovering function after earthquake as claimed in claim 1, wherein: the light steel keel framework of the end wall element in each combined shear wall is internally provided with a stiffening cross brace and a stiffening inclined brace, the diagonal positions of the light steel keel framework are also provided with steel plate structures, and the steel plate structures are fixedly connected with the light steel keel framework of the end wall element through self-tapping screws.
3. The composite shear wall capable of rapidly recovering function after earthquake as claimed in claim 1, wherein: the side length of the section of the steel tube concrete column is not less than the thickness of the end wall element.
