Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically to a prefabricated wall seismic protection structure. Background Technology

[0002] With the development of modern industrial technology, houses can be manufactured in batches, just like machine production. All that is needed is to transport the prefabricated house components to the construction site and assemble them. Because prefabricated buildings are quick to build and have low production costs, they have been rapidly promoted all over the world. They have the advantages of energy saving and fast construction. This type of building, which is assembled on the construction site from prefabricated components, is called a prefabricated building.

[0003] Chinese patent document CN213952579U discloses a vibration damping device for prefabricated building walls, including a vibration damping device body. Protective pads are provided at the left and right ends of the vibration damping device body. A supporting steel plate is fixed to the inner surface of the protective pads. An installation column is fixed to the surface of the supporting steel plate. A connector is fixedly connected to the surface of the supporting steel plate. A movable column is connected to the bottom end of the connector. A frame is provided in the middle of the vibration damping device body. An elastic filler is provided inside the frame. A central elastic device is provided in the middle of the frame.

[0004] However, when the above solution is used, the moving column moves from the middle of the elastic filler to the edge to buffer and reduce shock. The central elastic device can only buffer and reduce shock after the elastic filler is damaged, resulting in poor buffering and shock reduction effect and reducing the service life of the elastic filler.

[0028] Example 1

[0029] like Figure 1-3 As shown, the present invention proposes a prefabricated wall seismic protection structure, which includes a support plate 1, an elastic element 3, a connecting rod 4 and a spring 12.

[0030] There are two support plates 1, which are symmetrically arranged and have a gap between them. The end face of the support plate 1 is provided with a screw rod (shown in the diagram for illustration only) for installing the support plate 1 during use. The sides of the two support plates 1 and located in the gap are symmetrically provided with buffer components for shock absorption of the support plate 1 during use.

[0031] Elastic element 3 is provided on one side of the top and bottom of the buffer assembly. Elastic element 3 is one of the damping materials such as EVA, PE, CR, PU foam, PORON, and ACF. The side of elastic element 3 is provided with a limiting plate 2 that is connected to the buffer assembly and is used to limit the elastic element 3 during use.

[0032] There are multiple springs 12, and all of the multiple springs 12 are disposed inside the elastic member 3 and connected to the support plate 1.

[0033] There are two connecting rods 4. Both connecting rods 4 are installed on the side of the support plate 1 and extend to the end of the buffer assembly for connection. Both ends of the connecting rods 4 have rotating seats.

[0034] In this embodiment, the device is installed in the wall by the lead screw on the end face of the support plate 1. When an impact or vibration occurs, the force generated by the impact or vibration drives the support plate 1 to move towards the elastic member 3 along the direction of the force, so that the elastic member 3 can buffer it. At the same time, the multiple springs 12 inside the elastic member 3 are compressed or stretched by the movement of the support plate 1, so that the springs 12 can buffer the force on the support plate 1, further improving the shock absorption effect and avoiding damage to the elastic member 3. At the same time, when the support plate 1 moves, it drives the connecting rod 4 to move, so that the connecting rod 4 drives the buffer assembly to run, and forms a pressure buffer zone in the buffer assembly, further improving the buffering effect of the support plate 1 and significantly improving the shock absorption effect.

[0035] Example 2

[0036] like Figure 3 As shown, the present invention proposes a prefabricated wall earthquake protection structure. Compared with the first embodiment, the difference is that the other side of the elastic member 3 is provided with an installation groove 11, and the side of the support plate 1 is provided with a connecting block 14. When the elastic member 3 and the support plate 1 are installed together, the connecting block 14 is accommodated in the installation groove 11.

[0037] In an optional embodiment, multiple mounting holes 13 are provided on the other side of the elastic member 3, inside the mounting groove 11, and on the end face of the connecting block 14. The mounting holes 13 of the elastic member 3 and the connecting block 14 are arranged coaxially, and the spring 12 is located in the mounting holes 13 of the elastic member 3 and the connecting block 14 and connected to the support plate 1.

[0038] In this embodiment, when the support plate 1 is in use, it drives the connecting block 14 inserted in the mounting groove 11 to move, causing the connecting block 14 to deform the elastic element 3, thus buffering the support plate 1. At the same time, the spring 12 is connected to the support plate 1 through the mounting hole 13, so that the spring 12 directly pulls the support plate 1, further improving the buffering effect in use.

[0039] Example 3

[0040] like Figure 2 As shown, the present invention proposes a prefabricated wall earthquake protection structure. Compared with the first embodiment, the difference in this embodiment is that the buffer assembly includes a cylinder 5, a mounting plate 6, a sealing gasket 7, and a connecting rod 8.

[0041] The cylinder 5 is positioned between the two buffer components;

[0042] Mounting plate 6 is installed at the end and located inside the cylinder 5;

[0043] The sealing gasket 7 is installed on one side of the mounting plate 6 and located inside the cylinder 5, with its edge fitting and connected to the inside of the cylinder 5.

[0044] The connecting rod 8 is installed on the other side of the mounting plate 6 and extends to the outside of the cylinder 5 to connect with the connecting rod 4, and is used to reciprocate the mounting plate 6 inside the cylinder 5 during use.

[0045] In an optional embodiment, sleeves 15 are provided at both ends of the cylinder 5, and the sleeves 15 are sleeved on the outside of the connecting rod 8.

[0046] In this embodiment, while the support plate 1 drives the connecting rod 4 to move, the connecting rod 4 drives the mounting plate 6 and the sealing gasket 7 to move simultaneously inside the cylinder 5 via the connecting rod 8. This causes the sealing gasket 7 to compress the air inside the cylinder 5, forming a pressure buffer zone that effectively absorbs the impact force transmitted from the support plate 1.

[0047] Example 4

[0048] like Figure 2 As shown, the present invention proposes a prefabricated wall earthquake protection structure. The difference between this embodiment and embodiment three is that a cavity 10 is provided in the middle of the cylinder 5. The projected shape of the cavity 10 is circular. When the cylinder 5 and the mounting plate 6 are installed together, the mounting plate 6 is accommodated in the cavity 10.

[0049] In an optional embodiment, the outer dimension of the sealing gasket 7 is greater than the diameter of the cavity 10.

[0050] In an optional embodiment, a through hole 9 communicating with the cavity 10 is provided in the middle of the side of the cylinder 5 and on the side of the support plate 1.

[0051] In this embodiment, when the air in the cavity 10 is compressed by the mounting plate 6 and the sealing gasket 7 driven by the connecting rod 8, it is discharged to the outside of the cylinder 5 through the through hole 9 or the connecting rod 8, reducing pressure accumulation and improving the buffering effect. At the same time, the circular shape of the projected shape of the cavity 10 allows the mounting plate 6, the sealing gasket 7 and the connecting rod 8 to rotate in the cavity 10, so that the connecting rod 4 drives the connecting rod 8 to move in multiple directions, further improving the buffering effect.

[0052] In this invention, the device is installed in the wall via a lead screw on the end face of the support plate 1. When an impact or vibration occurs, the force generated by the impact or vibration drives the support plate 1 to move the connecting block 14 towards the elastic element 3 along the direction of the force. The connecting block 14 is inserted into the mounting groove 11, causing the support plate 1 to compress and deform the elastic element 3, thus allowing the elastic element 3 to dampen the support plate 1. Simultaneously, the spring 12 is directly connected to the support plate 1 through the mounting hole 13. When the support plate 1 moves, it causes multiple springs 12 to compress or extend, further buffering the force on the support plate 1 and improving the damping effect. The connecting rod 4 connects the connecting rod 8 to the support plate 1, so that the support plate 1, through the cooperation of the connecting rod 4 and the sleeve 15, drives the connecting rod 8 to move inside the cylinder 5. This causes the connecting rod 8 to simultaneously displace the mounting plate 6 and the sealing gasket 7 inside the cylinder 5, and causes the sealing gasket 7 to compress the air inside the cylinder 5. At the same time, the air is discharged to the outside of the cylinder 5 through the through hole 9 or the connecting rod 8, forming a pressure buffer zone and reducing pressure accumulation. This effectively absorbs the impact force transmitted from the support plate 1, further improving the buffering effect. The entire device can form a continuous buffering mechanism when an impact or vibration occurs, thereby protecting the wall or structure while avoiding damage that may be caused by the direct action of the impact force.

[0053] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
