Fabricated shear wall vertical joint connecting structure and accessories, application, calculation and construction of fabricated shear wall vertical joint connecting structure

Abstract

The invention discloses a fabricated shear wall vertical joint connecting structure and accessories, application, calculation and construction of the fabricated shear wall vertical joint connecting structure. According to the fabricated shear wall vertical joint connecting structure, a first prefabricated shear wall unit and a second prefabricated shear wall unit are connected together through connecting elements; one ends of the connecting elements are anchored into the second prefabricated shear wall unit, and the other ends of the connecting elements are anchored into the first and second prefabricated shear wall units; the connecting elements have tensile prestress in the vertical joint connecting structure, the connecting combination faces of the first prefabricated shear wall unit and the second prefabricated shear wall unit are mutually extruded under pull force of the connecting elements, and are fixedly connected under the combined action of friction force and the tension prestress of the connecting elements. The fabricated shear wall vertical joint connecting structure has the advantages of good seismic performance, convenient construction and high efficiency.

Description

technical field [0001] The invention relates to structural design of a prefabricated shear wall, special engineering supporting products and a construction method, in particular to a vertical joint connection structure of an prefabricated shear wall and its accessories, application, calculation and construction. Background technique [0002] At present, the connection between the vertical joints of the prefabricated shear wall is the connection form of steel bar connection and post-cast concrete, or the connection form of steel bar connection and post-grouting. Among them, in the connection form of steel bar connection and post-cast concrete, the steel bar connection must adopt an effective connection method and meet a specific connection length, and also install formwork and concrete pouring, which is a wet connection operation. The connection form of steel bar connection and post-grouting is in accordance with the connection method in the specification "Calculation Standar...

AI Technical Summary

Problems solved by technology

The connection form of steel bar connection and post-grouting is in accordance with the connection method in the specification "Calculation Standard for Prefabricated Concrete Pour GB / 51231-2016". There are nodes that cannot be constructed in this connection method

In addition, the current assembly technology in my country cannot achieve an assembly connection system that is equivalent to or better than the seismic performance of cast-in-place concrete structures.
