Technical Field

[0002] In recent years, prefabricated wall panels have been widely used in RC frame structures, but the research on their seismic performance is still insufficient. Existing prefabricated energy-absorbing infill walls mainly use methods such as wall panel slits and adding dampers to achieve the purpose of energy dissipation and shock absorption. The dampers use metal connectors as the main energy-absorbing elements, but these metal connectors are complex in structure, high in cost, and inconvenient in construction. In addition, the traditional prefabricated infill wall and the frame structure use a rigid connection, which will increase the overall lateral stiffness of the frame, and the horizontal seismic action borne by the structure will also increase accordingly. Summary of the invention

[0003] In order to solve the above technical problems, the utility model provides an assembled energy-absorbing filling wall structure which has simple structure, low cost, convenient construction, good shock-absorbing performance and can be assembled quickly.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0022] The utility model is further described below in conjunction with the accompanying drawings.

[0023] like Figure 1 As shown, the utility model comprises an RC frame 1, a plurality of square wall panels 6, a plurality of T-shaped energy absorbers 3 and four L-shaped energy absorbers 4. The RC frame 1 forms a square wall panel installation cavity, and an L-shaped energy absorber 4 is installed at each of the four corners of the wall panel installation cavity. The two ends of the outermost two wall panels facing the frame side are connected to the RC frame 1 through the L-shaped energy absorbers 4 respectively; the two ends of the opposite sides of the adjacent two wall panels 6 are connected to the RC frame 1 through the T-shaped energy absorbers 3 respectively.

[0024] like Figure 2-5 As shown, the T-shaped energy dissipator 3 includes two metal rings II 31 with T-shaped cavities. The two metal rings II are provided with screw grooves at the opposite ends of the side walls facing the RC frame, and the metal rings II are fixed to the RC frame 1 by screws. The two metal rings I are provided with screw grooves at the opposite ends of the side walls facing the wallboard, and the metal rings II are provided with screws 5 on the side walls facing the wallboard on the side walls of the corresponding wallboards. A gasket 7 is provided between the head of the screw 5 and the inner wall of the corresponding T-shaped energy dissipator 3.

[0025] like Figure 6-9 As shown, the L-shaped energy absorber 4 includes two metal rings 141 with L-shaped cavities. The opposite end of the metal ring 1 facing the side wall of the RC frame is provided with a screw groove, and the side wall of the metal ring 141 facing the RC frame is fixed to the RC frame 1 by screws 5; the opposite end of the metal ring 141 facing the side wall of the wall panel 6 is provided with a screw groove, and the side wall screws 5 of the metal ring 141 facing the wall panel are installed on the side of the corner of the corresponding wall panel 6. A gasket 7 is provided between the head of the screw 5 and the inner wall of the corresponding L-shaped energy absorber 4. The gap between two adjacent wall panels 6 and the gap between the top of the wall panel 6 and the inner wall of the RC frame 1 are filled with polyurethane foam 2.

[0026] The working principle of the utility model is as follows: under the action of horizontal earthquake, the RC frame 1 will undergo horizontal displacement, each wall panel 6 will undergo a certain lateral swing and shear displacement will occur between the wall panels. At the same time, a certain horizontal and rotational displacement will occur between the top of the wall panel 6 and the top beam of the RC frame 1. The polyurethane foam 2 filled in the gaps between the wall panels 6 and between the top of the wall panel 6 and the RC frame 1 has the characteristics of easy deformation and has a buffering effect. The T-shaped energy absorber 3 and the L-shaped energy absorber 4 are more prone to shear and extrusion deformation, thereby better playing an energy dissipation role. Since the wall panel 6 and the RC frame 1 are flexibly connected, there will be no large interaction between the wall panel 6 and the RC frame 1, which greatly reduces the overall anti-lateral displacement stiffness of the structure, and can further reduce the damage to the structure caused by the earthquake.
