Connection structure of integrally assembled concrete frame and shear wall

Abstract

The invention discloses a connection structure of integrally assembled concrete frame and shear wall. The connection structure comprises precast concrete columns, an H-shaped precast concrete composite beam, a precast concrete shear wall body, N-shaped horizontal connecting pieces, two U-bars, bolts, bolt sleeves and post-poured concrete. The U-bars are fixedly arranged on the upper and lower sides of the precast concrete shear wall body, the precast concrete columns, the precast concrete shear wall and the wall body are connected through the N-shaped horizontal connecting pieces, and a plurality of holes are reserved in the H-shaped precast concrete composite beam. After the connection structure is completed, each connecting part is cemented by the post-poured concrete to enable the columns, the wall and the beam to form an integral structure. According to the connection structure of the integrally assembled concrete frame and shear wall, the wall body is easy to lift and assemble, and accurate abutting joint of the upper and lower portions of the wall body can be realized, and quick assembling is facilitated.

Description

technical field [0001] The invention belongs to the technical field of prefabricated assembled concrete structures in civil engineering, in particular to an assembled integral concrete frame-shear wall connection structure, which is mainly applicable to assembled integral frame-shear wall structures. Background technique [0002] As a structural form in line with industrialized production methods, prefabricated concrete structures have the advantages of fast construction, convenient construction, greatly reducing the labor intensity of construction workers, improving the construction site environment, reducing noise pollution, reducing wet operations, and easy control of product quality. At the same time, prefabricated buildings can effectively save resources and energy, improve the efficiency of materials in achieving building energy conservation and structural performance, reduce the demand for site and environmental conditions for on-site construction, reduce the number of ...

Problems solved by technology

[0005] Chinese patent CN 102808465A uses the method of pouring mortar into the steel bar sleeve to connect the upper and lower steel bars, but this connection process requires high construction precision of the prefabricated parts. In actual construction, the weight of the entire shear wall is relatively large. It is difficult to control the alignment of the upper and lower steel bars in the hoisting state, and more steel bar sleeves are used in the construction, and the connection is time-consuming
