Self-supporting type double-faced laminated shear wall and construction method

Abstract

The invention provides a self-supporting type double-faced laminated shear wall and a construction method. The self-supporting type double-faced laminated shear wall comprises each laminated shear wall body, wherein each laminated shear wall body comprises two prefabricated wall bodies which are oppositely arranged in parallel at an interval, a vertical reinforcing steel bar penetrates through each prefabricated wall body, the extension part of each vertical reinforcing steel bar extends out of each prefabricated wall body, and the extension part is in lap joint with a ground beam or a pre-embedded vertical reinforcing steel bar of a lower-layer shear wall; the vertical reinforcing steel bars extending out of wall columns suspend the wall body, reinforcing steel bar binding or UHPC short lap joint is facilitated, the effective height of the section of the double-face laminated shear wall is increased, and the structural anti-seismic performance is improved. The prefabricated shear wall structure connected through a horizontal joint is high in assembly rate and easy to construct, long-time operation of large hoisting equipment is not needed, only inclined struts need to be adopted for fixing, the construction period can be greatly shortened, and the construction efficiency can be improved.

Description

technical field [0001] The invention relates to a self-supporting double-sided superimposed shear wall and a construction method. Background technique [0002] There are many horizontal and vertical joints and joints in the prefabricated shear wall structure, and the connection quality of these joints and joints directly affects the overall seismic performance of the shear wall structure. When encountering projects with prefabricated walls that are too high and heavy, it is difficult for ordinary prefabricated shear walls to guarantee the quality and efficiency of hoisting and construction, so double-sided laminated shear walls are gradually being promoted. At present, the connection method of prefabricated double-sided laminated shear walls is mainly through inserting ribs in the cavity, and then pouring concrete into the cavity to connect the upper and lower walls into a whole. The precision of prefabricated components and the construction quality of grouting are relativel...

Problems solved by technology

At present, the connection method of prefabricated double-sided laminated shear walls is mainly through inserting ribs in the cavity, and then pouring concrete into the cavity to connect the upper and lower walls into a whole. The precision of prefabricated components and the construction quality of grouting are relatively high. , it is not convenient for quality inspection, and because the upper and lower walls adopt the form of indirect overlapping of steel bars, the connection reliability has not been guaranteed. It is urgent to invent a new structural system to solve the above problems
