Post-casting system for fabricated shear wall without template

Abstract

The invention discloses a post-casting system for a fabricated shear wall without a template, and belongs to the technical field of connection of prefabricated building prefabricated components. The post-casting system comprises a first shear wall and a second shear wall, a vertical groove is formed in the end face of the first shear wall, and a plurality of stirrups are disposed in the vertical groove in the vertical direction at intervals; the second shear wall is provided with a plurality of flexible connectors inserted into the vertical groove, and the flexible connectors are arranged in the vertical direction at intervals; and concrete is poured into the vertical groove, and the concrete enables the first shear wall to be connected with the second shear wall. The post-casting system effectively avoids the current situation that the stirrups of edge members of the shear walls overlap each other and cannot be vertically installed, cast-in-place of vertical joints of the shear wallsis facilitated, and the safety of a structure is ensured; and at the same time, the process of supporting the template is omitted, and the assembly efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of connection of prefabricated building components, and in particular relates to a formwork-free post-casting system for a prefabricated shear wall. Background technique [0002] Prefabricated buildings refer to buildings in which some or all of the components of the building are prefabricated in the factory, then transported to the construction site, and the components are assembled through reliable connection methods. Specifically, after assembly at the construction site, usually between wall panels The vertical connection joints are cast-in-place, the main vertical stress-bearing steel grout anchor connection between the upper and lower wall panels, and the floor beams and slabs are superimposed and cast-in-site to form a whole. The advantage of this kind of building is that it can be constructed quickly, is less restricted by climate conditions, saves labor, and can improve the quality of construction. ...

AI Technical Summary

Problems solved by technology

[0004] At present, during the cast-in-place process of the vertical joints of shear walls in the prior art, the stirrups of adjacent shear walls overlap and interfere with each other. Since the stirrups are rigid, they cannot be directly installed vertically, so the installation must Destroy the stirrups of the shear wall first, and then restore the stirrups to their original state, which increases the structural insecurity; at the same time, when pouring concrete in the prior art, a large number of steel bars need to be tied, and formwork needs to be set at the same time. After the pouring is completed, The formwork also needs to be removed, resulting in inefficient assembly
