Description

Technical Field

[0001] This utility model relates to the field of building wall technology, specifically to an earthquake-resistant hollow steel mesh wall structure. Background Technology

[0002] In building construction, the seismic performance, ease of construction, and stability of walls have always been important research areas. Traditional wall structures have certain limitations in seismic resistance, and problems such as metal mesh panel vibration and positioning misalignment are prone to occur during construction, resulting in poor seismic performance. Furthermore, the construction process of traditional walls is complex, highly dependent on manual labor, and has low construction efficiency, making it difficult to meet the demands of rapid construction in modern buildings. Therefore, developing a new type of seismic-resistant wall structure has significant practical implications. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an earthquake-resistant hollow steel mesh wall structure, which solves the problems of poor seismic performance of the wall caused by vibration and positioning displacement during construction of existing wall structures, as well as the problems of complex construction process and low construction efficiency. By forming a rigid frame through truss reinforcement in the mesh plate intervals, the positioning displacement caused by steel bar vibration is effectively suppressed. Moreover, the truss structure is subjected to uniform stress, avoiding the risk of local stress failure caused by stress concentration. At the same time, the modular design of the overall structure makes the construction process simple and convenient, and greatly speeds up the construction efficiency.

[0004] To solve the above-mentioned technical problems, the present invention provides an earthquake-resistant hollow steel mesh wall structure, including a mesh panel, vertical keel and truss reinforcement. The mesh panel is assembled from multiple corrugated mesh sheets, which are symmetrically arranged to form continuous rhomboid hollow holes. The vertical keel is fixed in the rhomboid hollow holes, and the truss reinforcement is symmetrically arranged at the troughs of the mesh panel.

[0005] It also includes horizontal fixing components and vertical fixing components. The horizontal fixing components are fixedly installed at the upper and lower ends of the mesh plate, and the vertical fixing components are fixedly installed on both sides of the steel mesh wall structure.

[0006] The horizontal and vertical fasteners are both L-shaped components, and one side of each component is fixedly connected to the mesh panel.

[0007] It also includes reinforcing members, which are transverse tie bars, and multiple transverse tie bars are arranged along the entire length or not along the entire length on the surface of the mesh plate.

[0008] The transverse tie bars and truss bars are fixedly connected by tie wires, forming a whole.

[0009] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0010] This utility model utilizes a corrugated mesh panel with a concave-convex structure and prismatic hollow holes formed between the mesh panels to fix the mortar, forming a continuous structural column and cavity. A rigid frame is formed by fixing truss bars in the troughs of the mesh panel, which effectively suppresses the positioning displacement caused by the vibration of the reinforcing bars. Moreover, the truss structure is subjected to uniform stress, avoiding the risk of local stress failure caused by stress concentration. After the wall is completed, it has high wall rigidity, seismic resistance and stability. At the same time, the modular structure makes the construction process simple and convenient, greatly accelerating the construction efficiency. Attached Figure Description

[0016] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0017] like Figure 1-2 As shown, an embodiment of this utility model provides an earthquake-resistant hollow steel mesh wall structure, including a mesh panel 1, vertical keels 2, and truss reinforcement 3. The mesh panel 1 is assembled from multiple corrugated mesh sheets, which are symmetrically arranged to form continuous rhomboid hollow holes 4. The vertical keels 2 are fixed within the rhomboid hollow holes 4, and the truss reinforcement 3 is symmetrically arranged at the troughs of the mesh panel 1. This forms a closed, rigid columnar frame at the troughs of the mesh panel, providing a certain degree of vibration resistance compared to traditional walls during concrete pouring, and effectively suppressing the mesh panel positioning displacement caused by steel bar vibration.

[0018] In practical applications, the truss reinforcement 3 is set at the trough position on the grid plate 1. Both the upper and lower ends of the truss reinforcement 3 are fixedly connected to the main structure by rebar installation. The truss reinforcement 3 is symmetrically set at the trough position of the grid plate 1 and forms a hidden column by welding or wire binding to increase the seismic strength of the wall.

[0019] In this embodiment, the steel mesh wall structure also includes horizontal fixing members 5 and vertical fixing members 6. The horizontal fixing members 5 are fixedly installed at the upper and lower ends of the mesh plate 1, and the vertical fixing members 6 are fixedly installed on both sides of the steel mesh wall structure. Both the horizontal fixing members 5 and the vertical fixing members 6 are L-shaped components, and they are fixedly connected to the mesh plate and the main structure by means of nailing or welding. Since the steel mesh wall structure is fixed to the beams or floor slabs by the horizontal fixing members 5 and to the floor slabs by the vertical fixing members 6, and the two ends of the vertical keel 2 are respectively fixed to the horizontal fixing members 5 and the vertical fixing members 6, the steel mesh wall can transfer the force it bears to the beams and floor slabs at both ends through the truss reinforcement 3 and the vertical keel 2.

[0020] In this embodiment, the steel mesh wall structure also includes reinforcing members, namely horizontal tie bars 7. Multiple horizontal tie bars 7 are arranged along the entire length or not along the entire length on the surface of the mesh panel 1, with one end of each tie bar fixedly connected to the main structure, and the other parts fixedly connected to the truss reinforcement 3 by tie wires. The horizontal tie bars 7 are fixedly connected to the truss reinforcement 3 and the main structure to form a whole.

[0021] In practical applications, the two ends of the transverse tie bar 7 are generally connected to the main structure by anchoring, and the middle section of the transverse tie bar 7 is tied to the lower chord bar in the truss bar 3 by tie wire to form a whole, thereby enhancing the seismic resistance.

[0022] The working process of this utility model is as follows:

[0023] First, two wavy mesh panels are joined together to form mesh panel 1. The troughs are welded or tied with wire to create a structure with a rhomboid hollow hole 4. The overlapping parts of the mesh panels are also reinforced with wire ties. Then, vertical keels 2 are inserted into the rhomboid hollow holes 4, and the vertical keels 2 are fixed to the mesh panel 1 with a nail gun, providing support for the mesh panel 1 to facilitate its erection. According to the wall layout, horizontal fasteners 5 and vertical fasteners 6 are fixed to the main structure using nails, thus... A preliminary hollow steel mesh wall structure is formed; truss reinforcement 3 is set at the trough position of mesh plate 1, and the truss reinforcement 3 is fixedly connected to the main structure by rebar anchoring, and forms a hidden column by welding or wire binding to increase the seismic strength of the wall; finally, transverse tie bars 7 are set on mesh plate 1 and connected to the main structure by rebar anchoring, and the middle section and the lower chord of truss reinforcement 3 are bound together by wire binding to form an integral whole, enhancing the seismic resistance, and finally forming a complete seismic-resistant hollow steel mesh wall structure.

[0024] The core improvement of the earthquake-resistant hollow steel mesh wall lies in solving the problems of poor seismic performance, complex construction process, and low construction efficiency caused by vibration and positioning displacement during the construction of metal mesh walls through geometric structural innovation. By forming a rigid frame through truss reinforcement in the mesh plate intervals, the positioning displacement caused by steel bar vibration is effectively suppressed. Moreover, the truss structure is evenly stressed, avoiding the risk of local stress failure caused by stress concentration. At the same time, the modular structure of the whole makes the construction process simple and convenient, greatly accelerating the construction efficiency.

[0025] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
