Problems solved by technology

[0003] The connection of horizontal joints between prefabricated cavity shear walls is a key technology in the structure of prefabricated cavity shear walls. At present, the commonly used horizontal joint connection method is mainly post-cast concrete connection, which requires a lot of wet work on site. , the construction is complicated, the quality is difficult to guarantee, and it is not conducive to energy saving and environmental protection

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings:

[0022] As shown in the accompanying drawings, the present invention mainly includes an upper-layer prefabricated cavity shear wall sheet (1), a lower-layer prefabricated cavity shear wall sheet (2), a prefabricated floor slab (10), a grouting sleeve (5) and bolts (12). ).

[0023] For the upper-layer prefabricated cavity shear wall sheet (1) and the lower-layer prefabricated cavity shear wall sheet (2) according to the present invention, vertical cavities (4) are reserved in ordinary prefabricated shear walls at intervals. The cavity (4) divides the shear wall into a plurality of wall columns (3), and the two sides in the thickness direction of the vertical cavity (4) are cavity walls (9). The reinforcement of wall column (3) is similar to that of ordinary column, mainly including longitudinal reinforcement (6) and stirrup. The thickness of the cavity wall (9) is rel...

Abstract

The invention provides a horizontal joint tooth-groove dry-type connection structure of an assembly type cavity shear wall. The connection structure adapts to the characteristics of easy industrialized production of the assembly type cavity shear wall, and facilitates the industrialized production and on-site quick installation; sleeve connection is adopted for all main stress longitudinal ribs of the wall column sections of the cavity shear wall, distributing ribs of the cavity section are not connected vertically, and the connection form is simplified; the lower part of the cavity section of the upper cavity shear wall is provided with reserved grooves or an empty cavity for use as connecting grooves, and the upper part of the cavity section of the lower cavity shear wall is reserved with convex teeth which are meshed with the grooves, so that the shear-bearing capacity of the horizontal joint of the cavity shear wall is improved; bracket boards are prefabricated at the storey height of the cavity shear wall, the connecting end of a prefabricated floor is prefabricated as an L type, on-site direct bolt connection is made convenient, and the on-site construction quantity is reduced. According to the horizontal joint tooth-groove dry-type connection structure of the assembly type cavity shear wall, wet operation of a construction site is avoided, and industrialized production and green installation and construction are made convenient; the structure can be widely applied to precast assembly type concrete shear wall structures.

Description

technical field [0001] The invention relates to a horizontal joint tooth slot type dry connection technology of an assembled cavity shear wall, and belongs to the technical field of structural engineering. Background technique [0002] Prefabricated cavity shear wall structure means that various components of the structure, including prefabricated cavity shear walls, prefabricated beams, prefabricated floor slabs, etc., are standardized in the factory, and then the prefabricated components are bolted and welded on the construction site. or post-cast concrete structures. The fabricated cavity shear wall structure has light weight and good ductility. The prefabricated components are industrially produced, and the production process can be more refined than ordinary cast-in-place components. It has the advantages of saving labor, fast construction progress, and is conducive to the realization of building energy saving, and is convenient for industrial production and production....
