A connection component for a prefabricated shear wall and a prefabricated shear wall

Abstract

The invention discloses a connecting assembly for a fabricated shear wall. The connecting assembly comprises two fixed parts and two sliding parts, the two sliding parts are oppositely arranged, and each sliding part comprises a first side face. A plurality of first teeth are arranged on each first side face. The two fixed parts are the first fixed part and the second fixed part correspondingly, each fixed part is provided with a containing cavity with an open end, and each containing cavity comprises two opposite second side faces. A plurality of second teeth are arranged on each second sideface, the two sliding parts are arranged in the containing cavities of the first fixed parts, and the sliding parts can slide towards the corresponding second side faces so as to enable the multiple first teeth and the multiple second teeth to be connected to the fixed parts in a staggered occlusion mode. According to the connecting assembly for the fabricated shear wall, staggered occlusion of the teeth can be achieved, connection between the two fixed parts is achieved, operation is easy, and the structure is stable; and the two fixed parts are each arranged on a wall body, connecting of theconnecting assembly and the wall bodies can be achieved only through connecting of the fixed parts, and the construction step is simple.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a connection assembly for an assembled shear wall and an assembled shear wall. Background technique [0002] The existing prefabricated shear wall node connection technologies mainly include: [0003] 1. Grouting sleeve connection [0004] The main method of grouting sleeve connection is through a hollow cylindrical sleeve made of metal material with a certain wall thickness. The sleeve is reserved for grouting holes. The upper and lower walls are pre-embedded with steel bars, and the steel bars protrude from the outside of the wall. , when the walls are connected, insert the steel bars in the upper and lower walls from both ends of the sleeve, and then fill the sleeve with high-strength composite mortar added with expansion agent through the grouting hole, which fills the remaining gap inside the sleeve. In this way, the two steel bars are connected together t...

Problems solved by technology

[0007] However, the use of grouting sleeve connection, the cost of the sleeve is high, and the construction accuracy is high; the on-site construction of the grout-anchor lap joint with reserved holes is difficult, and the quality of the reserved holes is difficult to guarantee. In order to increase the range of the lap joint, it is necessary to increase The spiral stirrup is used to shorten the overlapping length of the steel bar, and the method of rotating and extracting the built-in threaded steel pipe is cumbersome, the process is not easy to control, and it is more labor-intensive

Moreover, the horizontal joints of the prefabricated wall panels with the above two connection methods have poor shear resistance and are prone to cracking, which reduces the bearing capacity of the structure
