Abstract

The invention discloses a fabricated shear wall unit which is characterized in that edge members are provided with longitudinal bars, the upper ends and the lower ends of the longitudinal bars extend out of concrete, the edge members are provided with notches for providing space for mounting connecting devices, and the longitudinal bars can pass through mounting holes formed in upper connecting plates or lower connecting plates of the corresponding connecting devices and are fixedly connected with the upper connecting plates or the lower connecting plates of the corresponding connecting devices. Therefore, the problems that quality detection is difficult and installation efficiency is low in grouting sleeve connection in an existing assembly type shear wall structure are solved.

Description

technical field [0001] The invention belongs to the field of prefabricated buildings, and in particular relates to a prefabricated shear wall unit. Background technique [0002] The connection methods of existing prefabricated shear walls along the building height direction mainly include grouting sleeve connection technology, reserved hole grout anchor lap connection technology and cast-in-place belt connection. Among them, the grouting sleeve connection is widely used in actual engineering and the construction technology is relatively mature, but there are still problems such as on-site docking difficulties, difficulty in ensuring the quality of grouting in the sleeve, and difficulty in later quality inspection; in addition, the diameter of the sleeve is relatively small. Large, in order to ensure the position of the longitudinal reinforcement in the shear wall, the thickness of the concrete protective layer outside the sleeve is relatively reduced, which may affect the lo...
