Construction method of fabricated slant steel plate mesh cast-in-place concrete shear wall

Abstract

The invention discloses a construction method of a fabricated slant steel plate mesh cast-in-place concrete shear wall. The construction method includes the steps that step 1, the number of layers of the shear wall is determined; step 2, a single-layer shear wall steel framework is constructed; step 3, a single-layer shear wall is cast in situ; step 4, a multi-layer shear wall steel framework is constructed; and step 5, a multi-layer shear wall is cast in situ. According to different building structures, inclined steel plate meshes are installed in a full-assembly mode to construct the shear wall steel framework, the combination form is variable and flexible, assembly is easy, transportation is light and convenient, universality is high, concrete is cast in place on site, the formed shear wall structure is stable, the construction cost can be effectively saved, and the assembly type characteristic is met; and inclined tensile stress is improved on an inner wall body and an outer wall body of the shear wall, so that crack diseases of the wall bodies are treated and prevented.

Description

technical field [0001] The invention belongs to the technical field of assembled cast-in-place shear walls, and in particular relates to a construction method for cast-in-place concrete shear walls with assembled oblique steel mesh sheets. Background technique [0002] Shear walls are also called wind-resistant walls, seismic walls or structural walls. Walls in houses or structures that mainly bear horizontal loads and vertical loads caused by wind loads or earthquakes to prevent structural shear damage are generally made of reinforced concrete. At present, my country is vigorously promoting the transformation of traditional buildings to industrialized buildings. In traditional buildings, most of the work needs to be tied up with steel cages and cast-in-place concrete at the construction site. The formed shear wall structure is relatively stable and the size is suitable. However, problems such as long construction period, large stockpiling site, and shortage of construction...

Problems solved by technology

In traditional buildings, most of the work needs to be tied up with steel cages and cast-in-place concrete at the construction site. The formed shear wall structure is relatively stable and the size is suitable. However, problems such as long construction period, large stockpiling site, and shortage of construction personnel have become Barriers to progress in the construction industry

Although the prefabricated prefabricated building has the advantages of higher construction level, it requires a variety of shaping molds for different building structures, resulting in poor versatility of the shear wall, and the formed shear wall is heavy and inconvenient to transport. In addition, the assembly process requires the assistance of large-scale machinery and equipment, and the positioning and reinforcement are difficult, and the process of adjusting the horizontal and vertical degree of the shear wall is cumbersome. The heavy workload leads to poor control of the construction progress, low construction efficiency, and poor construction accuracy. In addition, there are serious problems such as water leakage in the composite structure wall, and users are not satisfied with the prefabricated structure. It is difficult to promote the development of prefabricated structures.

At the same time, in the existing shear walls, whether they are cast-in-place shear walls or prefabricated shear walls, oblique cracks will be generated under the interference of the external environment, which will affect the stability and appearance of the wall
