Problems solved by technology
[0004] The above-mentioned vertical reinforcement connection technology for shear walls has problems such as additional vertical reinforcement, high requirements for on-site operations and construction accuracy, and increased on-site construction volume.
In addition, existing studies have found that when the vertical steel bars of prefabricated shear walls are cut off at the same height, horizontal cracks are likely to form at the joint positions of the vertical steel bars and the height of the reserved holes, and even develop into through joints.

The invention provides a prefabricated assembling whole type shear wall connected with a staggered-height vertical steel bar, comprising an upper-layer wall body and a lower-layer wall body, wherein the two ends of the bottom of the upper-layer wall body are provided with a first reserved hole and a second reserved hole, which are vertical; the vertical height of the second reserved hole is 1.2-1.5 times as much as the vertical height of the first reserved hole; a spiral stirrup which is as high as the first reserved hole and the second reserved hole is respectively pre-buried in each one of the first reserved hole and the second reserved hole; vertical steel bars at the inner side of an edge member of the lower-layer wall body are bundled by groups; a plurality of combined steel bar bundles are respectively inserted into the first reserved hole and the second reserved hole; and concrete mortar materials are filled between the steel bar bundles and the first reserved hole, and between the steel bar bundles and the second reserved hole. According to the prefabricated assembling whole type shear wall, the concrete of a pressed region can be effectively restricted and the prefabricated assembling whole type shear wall can be used for overlapping the vertical steel bars in a prefabricated shear wall system.
Description
technical field [0001] The invention belongs to the technical field of prefabricated concrete structures in construction engineering, and relates to a prefabricated and assembled integral shear wall using a staggered-height vertical reinforcement connection technology. Background technique [0002] The shear wall structure has high bearing capacity and anti-sway stiffness, can effectively resist horizontal shear force, and has good seismic performance. After the introduction of prefabricated assembly technology, the precast concrete assembly integral shear wall structure also has the advantages of facilitating factory standardized production, less wet work on site, convenient construction, less impact on the surrounding environment, and reduced transportation resources and labor resources. Therefore, with the actual needs of my country's construction industrialization and housing industrialization, the precast concrete assembly integral shear wall structure will have broad a...
