A kind of prefabricated cavity type medium thin-walled concrete shear wall

Abstract

The invention relates to the technical field of concrete shear walls, and discloses a precast cavity type middle-thin wall concrete shear wall. The middle-thin wall concrete shear wall comprises a wall body. A plurality of cavities penetrating in the height direction of the wall body are arranged at intervals in the length direction of the wall body. A connecting bar is arranged in each cavity, wherein the connecting bar comprises a plurality of connecting branch bars, one ends of the connecting branch bars are connected together, and the other ends of the connecting branch bars are circumferentially connected with the inner wall of the cavity to divide the cavity into a plurality of branch cavities, and each branch cavity is used for installing a pipeline. Longitudinal bars are arranged around the wall body in the height direction of the wall body. The outer hoop of each longitudinal bar is provided with a hooping. According to the middle-thin wall concrete shear wall, water and electricity pipeline installing is convenient, construction period prolonging caused by later period decorating is relived, meanwhile, the damage to the structure wall body caused by later period project installing is avoided, in addition, the using amount of materials is reduced, and the anti-seismic property of a component is improved.

Description

technical field [0001] The invention relates to the technical field of concrete shear walls, in particular to a prefabricated cavity-type thin-walled concrete shear wall, which solves the problem of installing hydropower pipelines that cannot be effectively solved by ordinary prefabricated concrete shear walls. Medium and thin-walled concrete shear walls are suitable for ordinary multi-story building structures. Background technique [0002] The prefabricated concrete structure refers to various components of the concrete structure, including prefabricated columns, prefabricated beams, prefabricated floors, prefabricated shear walls, etc., which are standardized in the factory, and then the prefabricated components are bolted, welded or prefabricated at the construction site. Stress connection installed structure. The prefabricated concrete structure has the advantages of saving labor force, fast construction progress, helping to achieve building energy conservation, and fa...

AI Technical Summary

Problems solved by technology

Generally speaking, the installation of hydropower pipelines in prefabricated concrete structures requires secondary construction during later construction, which seriously affects the construction period of prefabricated concrete structures, and it is difficult to meet the needs of building industrialization. Therefore, the installation of hydropower pipelines in prefabricated concrete structures is problematic. waiting to be solved
