Construction method of cast-in-place concrete shear wall with prefabricated oblique steel mesh

Abstract

The invention discloses a construction method for a cast-in-place concrete shear wall with an assembled oblique steel plate mesh, comprising steps: 1. Determining the number of layers of the shear wall; 2. Constructing a single-layer shear wall steel skeleton; 3. Casting in-situ Single-layer shear wall; 4. Construction of multi-layer shear wall steel skeleton; 5. Cast-in-place multi-layer shear wall. According to different building structures, the present invention adopts fully assembled oblique steel mesh to construct the steel skeleton of the shear wall. The combination form is changeable and flexible, the assembly is simple, the transportation is light, and the versatility is strong. The concrete is cast on site and the shear wall is formed. The structure is stable, which can effectively save construction costs and meet the characteristics of assembly. In addition, the use of oblique steel mesh can increase the oblique tensile stress on the inner and outer walls of the shear wall, and treat and prevent cracks in the wall.

Description

technical field [0001] The invention belongs to the technical field of prefabricated cast-in-situ shear walls, in particular to a construction method of prefabricated inclined steel mesh cast-in-situ concrete shear walls. Background technique [0002] Shear walls are also known as 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 are generally made of reinforced concrete to prevent structural shear damage. At present, my country is vigorously promoting the transformation of traditional buildings to industrialized buildings. In traditional buildings, most of the work needs to bind steel cages and cast-in-place concrete at the construction site. The formed shear wall structure is relatively stable and the size is appropriate. However, problems such as long construction period, large stacking site, and shortage of construction personnel have become a pr...

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
