Description

Technical Field

[0001] The utility model relates to the technical field of shear walls, in particular to a steel frame cast-in-situ concrete shear wall structure. Background Art

[0002] The existing shear wall is a wall structure mainly cast with steel bars and concrete to ensure earthquake resistance;

[0003] After searching, the application with patent number CN202021018807.5 discloses a steel-concrete composite structural frame-cast-in-situ concrete shear wall structure system, including steel end columns and shear wall bodies. The shear wall bodies are made of double-layer horizontal and vertical distribution bars evenly welded and cast-in-situ concrete. The horizontal and vertical distribution bars run through the concrete wall body and overlap with the reserved steel bars of the steel end columns set on both sides of the shear wall body. The steel end columns are set on both sides of the shear wall body and serve as edge members. The shear wall body is cast in the exterior wall section, stairwell section, or elevator section.

[0004] The above application documents increase assembly efficiency by changing prefabricated walls into cast walls. However, the use of horizontal and vertical reinforcements as the main supporting structure is not convenient for construction and subsequent casting. Multiple clips are required to clamp the contact points between the vertical reinforcement and the horizontal reinforcement. The large number of contact points leads to low work efficiency. In addition, the amount of concrete cast at the contact point between the horizontal reinforcement and the vertical reinforcement is large, and the stability is limited.

[0005] Therefore, we proposed a steel frame cast-in-place concrete shear wall structure. Utility Model Content

[0006] In view of the deficiencies of the existing technology, the utility model provides a steel frame cast-in-situ concrete shear wall structure, which solves the problems of more concrete bodies cast outside the existing transverse reinforcement, heavy hanging weight and limited stability.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a steel frame cast-in-situ concrete shear wall structure, comprising two groups of side columns and transverse reinforcement therebetween, a reinforcing column is set between the two groups of side columns, and reinforcing bars are clamped on the transverse reinforcements;

[0008] The reinforcing ribs are rectangular ribs with inwardly concave sides.

[0009] Preferably, the four corners of the inner side of the reinforcing rib are respectively clamped on the outer sides of the four groups of opposite transverse ribs, and the outer wall of the inwardly recessed portion of the reinforcing rib is tightly attached to the inner side of the middle transverse rib from the inside to the outside;

[0010] Among them, the setting of the shape of the reinforcement bar can limit the relative position on the transverse bar from the outside to ensure its stability.

[0011] Preferably, the reinforcing ribs are clamped on the circumferential sides of three groups of transverse ribs arranged vertically;

[0012] Among them, one group of reinforcing bars can simultaneously limit and clamp the three groups of arranged transverse bars, with good clamping effect, simple operation and high work efficiency.

[0013] Preferably, the side columns are H-shaped steel, and the side walls of the side columns are provided with external reinforcement holes that match the specifications of the transverse reinforcement;

[0014] Among them, the setting of the external reinforcement holes facilitates the construction of the transverse reinforcement from both ends.

[0015] Preferably, the reinforcement column is a U-shaped steel, and a reinforcing rib hole that is compatible with the specifications of the side column and passes through is opened on the reinforcement column;

[0016] The arrangement of the reinforcement column facilitates ensuring its own firmness by building concrete inside the column.

[0017] Preferably, the transverse reinforcement is a U-shaped reinforcement, and concrete is cast in both the side columns and the reinforcement columns.

[0018] The utility model provides a steel frame cast-in-place concrete shear wall structure. It has the following beneficial effects:

[0019] The steel frame cast-in-place concrete shear wall structure can ensure the lateral support of the wall by using the transverse reinforcement and the reinforcement reinforcement thereon. The reinforcement reinforcement is directly mounted on the outside of the transverse reinforcement to clamp the transverse reinforcement around the circumference to ensure its stability. The reinforcement column ensures the firmness of the middle part of the transverse reinforcement, thus solving the problem that there is a large amount of concrete cast on the outside of the existing transverse reinforcement, the hanging weight is heavy and the stability is limited.
