Description

Technical Field

[0001] This utility model relates to the field of shear wall technology, and in particular to a reinforced double-sided composite shear wall. Background Technology

[0002] Double-sided composite shear wall structures are semi-precast and semi-cast-in-place concrete structures, absorbing the advantages of both cast-in-place and precast concrete structures. They feature high-quality precast components and good overall integrity of cast-in-place connections, meeting the needs of residential industrialization and are increasingly used in the construction field. Currently, the fabrication methods for double-sided composite shear walls both domestically and internationally generally include steps such as arranging reinforcement, pouring concrete on one side, concrete vibration, curing, pouring concrete on the other side, flipping the poured concrete slab and pressing it to a predetermined height, and on-site pouring. This processing method allows for the precasting of the double-sided composite shear wall, is simple to operate, and has good economic benefits. However, the commonly used shear wall fabrication method means that only one side of the steel mesh on the resulting shear wall panel forms a reliable connection with the truss reinforcement, while the steel mesh on the other side is not connected. This makes it difficult to form effective lateral restraint between the two precast wall panels, significantly weakening the connection performance between the steel truss and the steel mesh in the precast wall panel, and reducing the overall seismic performance of the shear wall structure. Meanwhile, due to the difference in lateral constraint between the precast wall panels on both sides, the lateral effect on the precast wall panels on both sides is significant when the concrete in the middle cavity is poured, which greatly affects the stability of the entire composite wall.

[0003] The existing production method of double-sided composite shear walls limits the lateral constraint difference between the two precast wall panels, which greatly weakens the connection performance between the steel truss and the steel mesh in the precast wall panels, reduces the seismic performance of the overall shear wall structure, and when pouring the concrete in the middle cavity, the lateral squeezing effect of the post-poured concrete on the two precast wall panels is significant, which greatly affects the stability of the entire composite wall. Utility Model Content

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a reinforced double-sided composite shear wall, which solves the technical problem that the existing production method of double-sided composite shear walls limits the lateral constraint difference between the two precast wall panels, greatly weakens the connection performance between the steel truss and the steel mesh in the precast wall panels, and reduces the seismic performance of the overall shear wall structure.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A reinforced double-sided composite shear wall includes a first precast concrete panel with reinforcing mesh and a second precast concrete panel with reinforcing mesh, and a steel truss disposed between the first and second precast concrete panels with reinforcing mesh. The steel truss is arranged alternately between the first and second precast concrete panels with reinforcing mesh to increase the lateral constraint between the first and second precast concrete panels with reinforcing mesh.

[0009] Preferably, there is a gap between the first precast concrete panel with reinforcing mesh and the second precast concrete panel with reinforcing mesh.

[0010] Preferably, concrete is poured at the gap between the first precast concrete panel with reinforcing mesh and the second precast concrete panel with reinforcing mesh.

[0011] Beneficial effects

[0012] First, by arranging steel trusses alternately in the cavity of the double-sided composite shear wall, effective lateral restraint is provided between the first and second precast concrete panels with steel mesh, effectively resisting the lateral force of concrete on both sides of the precast panels when the concrete in the cavity is poured. This greatly improves the lateral restraint and seismic performance inside the shear wall, meeting people's increasingly higher quality requirements for building design. Attached Figure Description

[0018] This application provides a reinforced double-sided composite shear wall, which effectively solves the problem that the existing production method of double-sided composite shear walls limits the lateral constraint difference between the two precast wall panels, greatly weakens the connection performance between the steel truss and the steel mesh in the precast wall panels, and reduces the seismic performance of the overall shear wall structure. This reinforced double-sided composite shear wall arranges the steel truss in a staggered arrangement in the cavity of the double-sided composite shear wall, providing effective lateral constraint between the first precast concrete panel with steel mesh and the second precast concrete panel with steel mesh. This effectively resists the lateral action of the concrete on the two precast panels when the concrete in the cavity is poured, greatly improving the lateral constraint force and seismic performance inside the shear wall, and meeting people's increasingly higher quality requirements for building construction.

[0019] Example: Figure 1 and Figure 2 As shown, the technical solution in this embodiment effectively solves the technical problem that the existing production method of double-sided composite shear walls limits the lateral constraint difference between the two precast wall panels, greatly weakens the connection performance between the steel truss and the steel mesh in the precast wall panel, and reduces the seismic performance of the overall shear wall structure. The overall idea is as follows:

[0020] To address the problems existing in the prior art, this utility model provides a reinforced double-sided composite shear wall, including a precast concrete panel 1 with reinforcing mesh and a precast concrete panel 3 with reinforcing mesh, and a steel truss 2 disposed between the precast concrete panel 1 with reinforcing mesh and the precast concrete panel 3 with reinforcing mesh. The steel truss 2 is arranged alternately between the precast concrete panel 1 with reinforcing mesh and the precast concrete panel 3 with reinforcing mesh to increase the lateral constraint between the precast concrete panel 1 with reinforcing mesh and the precast concrete panel 3 with reinforcing mesh. There is a gap between the precast concrete panel 1 with reinforcing mesh and the precast concrete panel 3 with reinforcing mesh, and concrete is poured at the gap between the precast concrete panel 1 with reinforcing mesh and the precast concrete panel 3 with reinforcing mesh.

[0021] The steel truss 2 is arranged alternately in the cavity of the double-sided composite shear wall, providing effective lateral restraint between the precast concrete panel 1 with steel mesh and the precast concrete panel 3 with steel mesh. This effectively resists the lateral action of the concrete on the two precast panels when the concrete in the cavity is poured, greatly improving the lateral restraint and seismic performance inside the shear wall, and meeting people's increasingly high quality requirements for building design.

[0022] In the factory production of this reinforced double-sided composite shear wall, precast concrete panel 1 with reinforcing mesh and steel truss 2 constitute panel A, and precast concrete panel 3 with reinforcing mesh constitutes panel B. During production, panel A is poured first. After the concrete in panel A reaches its strength, the concrete in panel B is poured. Before the concrete in panel B initially sets, panel A is inverted and placed onto panel B, completing the production process. Figure 3 As shown.

[0023] Working principle:

[0024] The steel truss 2 is arranged alternately in the cavity of the double-sided composite shear wall, providing effective lateral restraint between the precast concrete panel 1 with steel mesh and the precast concrete panel 3 with steel mesh. This effectively resists the lateral action of the concrete on the two precast panels when the concrete in the cavity is poured, greatly improving the lateral restraint and seismic performance inside the shear wall, and meeting people's increasingly high quality requirements for building design.

[0025] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
