Description

Technical Field

[0001] This application relates to the technical field of prefabricated wall panel structures, and in particular to an earthquake-resistant prefabricated wall panel structure. Background Technology

[0002] Precast wall panels are building components manufactured in factories or on production lines, typically using materials such as concrete, steel, and wood. The size and shape of precast wall panels can be customized according to design requirements, and they are transported to the site for installation after manufacturing. Using precast concrete wall panels in construction reduces noise and pollution, minimizes on-site wet work, and can significantly shorten the construction cycle of buildings.

[0003] In existing technologies, to address seismic resistance issues in building structures, elastic panels with elastic buffers are typically added to the walls to enhance seismic performance. However, these elastic panels are usually planar, limiting their buffering capacity and thus their effectiveness in resisting seismic damage to precast wall panels. Therefore, further improvements are needed. Utility Model Content

[0004] To address the above problems, this application provides a seismic-resistant precast wall panel structure.

[0005] This application provides a seismic-resistant precast wall panel structure, which adopts the following technical solution:

[0006] An earthquake-resistant precast wall panel structure includes a wall panel body and a shock-absorbing sandwich layer built into the wall panel body. The wall panel body includes two outer walls. The shock-absorbing sandwich layer includes a fixed layer built into the two outer walls, two elastic layers respectively disposed on both sides of the fixed layer, and a wire mesh disposed between the elastic layer and the fixed layer or between the fixed layer and the outer wall. The cross-section of the elastic layer along its thickness direction is wavy.

[0007] By adopting the above technical solution, a shock-absorbing sandwich layer is set inside the wall panel. The elastic layer is set to provide a certain buffer, and because its cross-section along its thickness is set in a wave shape, it can deform to a certain extent and improve the seismic resistance. The steel wire mesh strengthens the connection stability between the layers and ensures that the overall structure is not easy to separate under stress.

[0008] Preferably, the wave trends of the two elastic layers are staggered.

[0009] By adopting the above technical solution, the two elastic layers within the main body of the wall panel are staggered due to the wave trend, which can effectively disperse and absorb vibration energy from different directions, further improving the overall seismic performance of the precast wall panel. Furthermore, this staggered arrangement enhances the mutual support between the elastic layers, reducing structural deformation caused by vibration, thereby improving the stability and safety of the precast wall panel under earthquakes or other external forces.

[0010] Preferably, the elastic layer comprises a plurality of corrugated sheets, with deformation joints formed between adjacent corrugated sheets.

[0011] By adopting the above technical solution, the elastic layer of the wall panel is composed of several corrugated sheets. The design of the corrugated sheets allows the elastic layer to undergo controllable deformation when subjected to external forces, thereby absorbing and dispersing vibration energy and reducing the direct impact of vibration on the main body of the wall panel. At the same time, the existence of expansion joints further improves the flexibility of the elastic layer, allowing it to deform in different directions, reducing the possibility of damage or collapse due to stress concentration, and significantly improving the overall stability and safety of the precast wall panel.

[0012] Preferably, the side of the elastic layer closest to the wire mesh is arranged in a honeycomb pattern, and the shock-absorbing sandwich layer further includes an adhesive damping layer filled between the elastic layer and the fixing layer.

[0013] By adopting the above technical solution, the side of the elastic layer near the wire mesh is arranged in a honeycomb pattern, which can effectively disperse and absorb vibration energy, reduce the force of vibration transmitted to the main body of the wall panel, and also reduce its own weight. At the same time, the adhesive damping layer filled between the elastic layer and the fixed layer further enhances the shock absorption effect, converting vibration energy into heat energy through damping, thereby effectively preventing the wall panel from being damaged or collapsing during vibration and improving the overall safety of the precast wall panel.

[0014] Preferably, a transition layer is provided between the wire mesh and the elastic layer.

[0015] By adopting the above technical solution, a transition layer is set between the elastic layer and the wire mesh in the main body of the wall panel, and fibers are incorporated into the transition layer, which effectively improves the tensile strength of the transition layer. When subjected to vibration, the transition layer can better transmit and disperse stress, thereby significantly improving the overall seismic performance of the precast wall panel.

[0016] Preferably, the transition layer is a high-ductility cement-based composite material transition layer.

[0017] By adopting the above technical solution, the high-ductility cement-based composite transition layer exhibits high crack resistance and high ductility, which can further improve the overall seismic performance and structural stability of the wall panel. Furthermore, in conjunction with fibers, it can enhance the energy dissipation capacity of the wall panel structure.

[0018] Preferably, a connecting plate protrudes from opposite sidewalls or opposite ends of the fixing layer, and the elastic layer is disposed between the two connecting plates. The surfaces of the two connecting plates that are close to each other are provided with slots for the elastic layer to be inserted.

[0019] By adopting the above technical solution, the fixing layer inside the wall panel is equipped with a connecting plate, and a slot is opened on the connecting plate to embed the elastic layer. This can effectively improve the connection stability between the elastic layer and the fixing layer, making the elastic layer less likely to shift or fall off when subjected to vibration, thereby further enhancing the overall seismic performance of the precast wall panel.

[0020] Preferably, one of the elastic layers is provided with a sound-insulating layer.

[0021] By adopting the above technical solution, after adding a sound insulation layer on the elastic layer, the sound insulation effect of the precast wall panel can be significantly improved on the basis of the original shock absorption function, thus solving the defect of unsatisfactory sound insulation of traditional precast wall panels.

[0022] In summary, this utility model has the following beneficial effects:

[0023] 1. By setting a shock-absorbing sandwich layer inside the wall panel body, in which the elastic layer is set in a corrugated shape and combined with steel wire mesh, the seismic performance of the wall panel can be significantly improved, effectively reducing the risk of damage and collapse of the wall panel body during vibration;

[0024] 2. The structural design between the elastic layer and the fixed layer, combined with the effect of the adhesive damping layer, further optimizes the energy absorption and dispersion capabilities, and improves the overall structural stability. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail below.

[0030] This application discloses an earthquake-resistant prefabricated wall panel structure.

[0031] Example 1:

[0032] A seismic-resistant precast wall panel structure, referring to Figure 1 The wall panel body 1 includes a shock-absorbing sandwich layer 2 built into the wall panel body 1. The wall panel body 1 includes two outer walls 11, which are made of concrete. The shock-absorbing sandwich layer 2 is located between the two outer walls 11. The shock-absorbing sandwich layer 2 specifically includes a fixed layer 21 built into the two outer walls 11, two elastic layers 22 respectively disposed on both sides of the fixed layer 21, a wire mesh 23 disposed between the elastic layer 22 and the fixed layer 21 or between the fixed layer 21 and the outer wall 11, and an adhesive damping layer 24 filled between the elastic layer 22 and the fixed layer 21.

[0033] The fixed layer 21 has connecting plates 211 protruding from opposite sidewalls or opposite ends. The elastic layer 22 is disposed between the two connecting plates 211. The surfaces of the two connecting plates 211 that are close to each other have slots 212 for the elastic layer 22 to be inserted. Both the fixed layer 21 and the connecting plates 211 can be made of high-strength concrete or lightweight alloy materials. The design of the slots 212 ensures a tight fit between the elastic layer 22 and the fixed layer 21, reduces the possibility of displacement of the elastic layer 22 during vibration, and further improves the overall strength of the wall panel.

[0034] The elastic layer 22 can be made of high-strength plastic materials, such as polypropylene or polyethylene, or rubber materials to ensure good elasticity and toughness, or it can be made of elastic steel, depending on the requirements. In this embodiment, the elastic layer 22 is plate-shaped, and the cross-section of the elastic layer 22 along its thickness direction is wavy. The wavy shape can be designed as a sine wave or other periodic curve shape. It should be noted that the wave trends of two elastic layers 22 can be staggered to absorb and disperse vibration energy in different directions.

[0035] Specifically, the wire mesh 23 is installed between the elastic layer 22 and the outer wall 11. As a key component connecting the elastic layer 22 and the fixed layer 21, the wire mesh 23 can be made of galvanized steel wire or stainless steel wire to improve corrosion resistance and strength. The mesh shape of the wire mesh 23 can be designed as diamond or round, and the specific size can be adjusted according to actual needs.

[0036] In this embodiment, a transition layer 3 is provided between the wire mesh 23 and the elastic layer 22, and the transition layer 3 extends between the outer wall 11 and the wire mesh 23. In this embodiment, the transition layer 3 can be a high-ductility cement-based composite material (ECC) transition layer 3, or a transition layer 3 made of high-ductility concrete or ultra-high performance concrete, depending on the requirements. In this embodiment, fibers are incorporated into the transition layer 3, and the fibers can be carbon fiber or glass fiber. The addition of these fiber materials can significantly improve the strength and toughness of the transition layer 3, while improving its crack resistance.

[0037] The adhesive damping layer 24 can be made of materials such as silicone or polyurethane adhesive, which have good adhesion and damping properties, and can further absorb vibration energy and reduce noise transmission.

[0038] The implementation principle of the earthquake-resistant precast wall panel structure in this application embodiment is as follows: By setting a damping sandwich layer 2 inside the wall panel body 1, the wave-like structure of the elastic layer 22 can effectively absorb and disperse vibration energy, thereby significantly improving the earthquake resistance of the wall panel. At the same time, the addition of the adhesive damping layer 24 reduces the transmission of noise caused by vibration and improves the sound insulation effect of the wall panel, while the wire mesh 23 enhances the connection strength between the layers and ensures the overall stability of the wall panel.

[0039] Example 2:

[0040] Reference Figure 2 The difference from Embodiment 1 is that the side of the elastic layer 22 closest to the wire mesh 23 is arranged in a honeycomb pattern, which not only enhances the overall strength of the elastic layer 22, but also increases the contact area between it and the wire mesh 23, which helps to improve the stability of the connection.

[0041] One of the elastic layers 22 is provided with a sound insulation layer 25 to improve the sound insulation effect of the entire wall panel. The sound insulation layer 25 can be made of polyester fiber sound-absorbing cotton, mineral wool board or glass wool.

[0042] Example 3:

[0043] Reference Figure 3 The difference from Embodiment 1 is that in this embodiment, the elastic layer 22 includes a plurality of corrugated sheets 221, and a deformation joint 222 is formed between adjacent corrugated sheets 221. The design of the deformation joint 222 allows the elastic layer 22 to undergo controllable deformation when subjected to vibration, thereby absorbing vibration energy.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
