Problems solved by technology

However, since the horizontal holes and the longitudinal holes in the panel are connected with each other, during the construction process, both vertical and horizontal reinforcements must be pierced in the longitudinal holes, and the number of reinforcements is large and mutually blocking. , the horizontal reinforcement cannot penetrate because of the obstruction of the vertical reinforcement, and the concrete vibrator cannot be placed because of the obstruction of the vertical reinforcement

Abstract

The invention discloses a prefabricated edge member, a preparation method, a formed shear wall structure and a construction method. The prefabricated concrete edge member comprises plate body vertical bars, wherein the plate body vertical bars are partly or wholly non linear type steel bars. The concrete shear wall structure is formed by splicing of two prefabricated concrete edge members up and down, wherein the extension parts of the non linear type steel bars of one of the prefabricated concrete edge members stretch into first longitudinal holes of the other prefabricated concrete edge member. The plate body vertical bars are pre-embedded in the concrete in the plate body, a vertical steel bar is not needed to additionally penetrate through the first longitudinal holes, and it is ensured that the vertical steel bar and a steel bar transversely penetrated do not mutually obstruct. According to the shear wall structure, a single vertical steel bar penetrating through the first longitudinal holes can be reduced, the using amount of the steel bar is reduced, meanwhile, the construction workload is relieved, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the field of prefabricated buildings, in particular to a concrete prefabricated edge component. Background technique [0002] At present, in order to improve the problems of slow construction speed and messy construction site caused by the traditional building construction method of binding steel bars first and then pouring concrete, the construction industry has implemented industrialized construction methods, which not only increase the speed, but also make the construction site clean and tidy. And can save energy and reduce emission, protect the environment. [0003] In the industrialized construction method, large-area ordinary walls, corners, and walls where doors and windows are installed are all assembled with prefabricated components. Among them, the prefabricated components assembled into walls for installing doors and windows are not only complex in structure, but also if the design is unreasonable, the strength of t...
