Embodiment 1

[0040] Such as figure 1 Shown here is a prefabricated cavity type medium-thin-wall concrete shear wall provided by the present invention. The cross section of the wall 1 is rectangular; the concrete is prefabricated ordinary concrete, which is mainly used for compressing components. The cavity 2 is a reserved hole, the hole is rectangular, and its cross section is designed with a performance-based design method; the reserved hole is the middle part of the wall section of the component, so after a hole is reserved in this part, the structure is affected Compressive capacity and shear capacity are less affected.

[0041] It can be seen from the above embodiments that the prefabricated cavity type medium-thin-walled concrete shear wall of the present invention has cross-sectional dimensions, concrete wall thickness, cavity 2 dimensions, longitudinal reinforcement 4 area, stirrup 5 area, and connecting reinforcement The area and size of 6 are designed using performance-based design m...

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 medium-thin-walled concrete shear wall, which solves the problem of installation of water and electricity pipelines that cannot be effectively solved by ordinary prefabricated concrete shear walls. The prefabricated cavity type The thin-walled concrete shear wall is suitable for ordinary multi-high-rise building structures. Background technique [0002] The prefabricated concrete structure refers to the various components of the concrete structure, including prefabricated columns, prefabricated beams, prefabricated floor slabs, prefabricated shear walls, etc., are standardized in the factory, and then the prefabricated components are connected by bolts, welded or prefabricated at the construction site. The structure is assembled by stress connection. The prefabricated concrete structure has the advantages of saving labor, fast construction pro...
