Description

Technical Field

[0001] This utility model relates to the field of steel plate shear walls, and in particular to a spliced ​​steel plate shear wall. Background Technology

[0002] There are currently two main types of concrete shear walls: cast-in-place shear walls and prefabricated shear walls. Prefabricated shear walls are also mainly divided into two types: fully prefabricated and partially prefabricated.

[0003] The formwork engineering of cast-in-place shear walls is an important sub-project with high requirements and long time consumption. After the concrete is poured, bulging and grout leakage are common problems. In addition, there are problems such as a large number of on-site workers, long initial setting time after pouring, many overlapping procedures, and a large impact on the environment.

[0004] While prefabricated concrete shear walls have advantages such as less wet work and shorter construction period, the heavy weight of the prefabricated walls increases costs and construction difficulty during transportation and hoisting. At the same time, at the post-cast joints of prefabricated shear walls, the requirements for steel bar connection methods make the steel bars numerous and difficult to tie, and formwork is also required, making quality control difficult. Utility Model Content

[0005] The purpose of this utility model is to provide a spliced ​​steel plate shear wall, which aims to solve the technical problems of difficult reinforcement binding at the joints of prefabricated shear walls, difficulty in controlling the quality of post-pouring at the joints, and high transportation and hoisting costs caused by the heavy weight of prefabricated walls.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:
