Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building engineering, in particular to a steel cage with concealed columns and a prefabricated reinforced concrete composite wall component thereof. Background Art
[0002] Double-sided composite shear wall can also be called composite wall. It is usually prefabricated in the factory and then hoisted to the construction site for assembly. It is a type of precast concrete structure. The hidden column is a building component formed by casting a steel cage. The width of the hidden column is the same as the wall body. It is hidden in the wall and difficult to identify, hence the name. At the same time, the hidden column is part of the shear wall and is the edge component of the shear wall. It is mainly used to bear the in-plane bending moment of the wall.
[0003] When the existing hidden column is assembled with the composite wall, the steel bars are usually exposed on the side of the prefabricated composite wall, and the vertical steel bars are pre-implanted in the market site. After the composite wall is hoisted to the construction site, it is fixed to the pre-buried vertical steel bars on site and multiple vertical steel bars are connected by fixing stirrups. Then, the construction of the hidden column is completed by casting concrete through formwork. After the hidden column is formed, the hidden column and the composite wall are mainly supported by concrete tensioning and several previously exposed steel bars of the composite wall. The concrete is not well constrained between the steel bars, and the composite wall is easily separated from the hidden column under the action of a large axial compression ratio. Utility Model Content
[0004] Based on this, the purpose of the utility model is to provide a steel cage with concealed columns and a prefabricated reinforced concrete composite wall component thereof to solve the technical problems mentioned in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel cage with hidden columns and a prefabricated reinforced concrete composite wall component thereof, comprising a first wall panel and a second wall panel, both sides of the first wall panel and the second wall panel are connected with hidden column bodies, and the inside of the two hidden column bodies are connected with third vertical bars, the outer surface of the third vertical bars is connected with stirrups, and one side of the third vertical bars is connected with second tension bars.
[0006] By adopting the above technical solution, the third vertical reinforcement is directly fixed to the first vertical reinforcement and the second vertical reinforcement in the composite wall, and the connection between the first vertical reinforcement, the second vertical reinforcement and the third vertical reinforcement is reinforced by the second tension reinforcement, so that the tensile capacity of the structure is increased. At the same time, the stirrups fix the multiple third vertical reinforcements distributed in a rectangular array to form a steel cage, so that the later cast hidden column can form a whole with the composite wall.
[0007] Furthermore, a plurality of the third vertical ribs are provided, and the plurality of third vertical ribs are distributed in a rectangular array, and the plurality of the third vertical ribs are divided into two groups.

[0014] By adopting the above technical scheme, the first vertical reinforcement and the first transverse reinforcement are fixed to form a steel mesh in the first wall panel, and the second vertical reinforcement and the second transverse reinforcement are fixed to form a steel mesh in the second wall panel. Through the steel truss, the first tension reinforcement and the saddle reinforcement connected between the first wall panel and the second wall panel, the two ends of the first tension reinforcement respectively fix the steel mesh in the first wall panel and the steel mesh in the second wall panel, thereby increasing the tensile capacity of the composite wall panel and preventing the weight of the subsequent pouring of concrete from separating the first wall panel from the second wall panel. At the same time, the steel truss and the saddle reinforcement support the first vertical reinforcement, the first transverse reinforcement, the second vertical reinforcement and the second transverse reinforcement, and the saddle reinforcement ensures that the spacing between the first vertical reinforcement, the first transverse reinforcement, the second vertical reinforcement and the second transverse reinforcement is consistent and stable, so that the skeleton composed of multiple steel bars forms an overall stable structure, and thus the precast reinforced concrete composite wall has good overall force-bearing performance and high connectability.
