Description

Technical Field

[0001] This utility model relates to the field of earthquake-resistant building protection technology, specifically to an earthquake-resistant building wall protection device. Background Technology

[0002] Earthquake-resistant building protection devices refer to specialized systems installed in buildings to mitigate earthquake damage through mechanical structure design and energy dissipation principles.

[0003] Currently, most seismic protection devices for building walls adopt rigid support structures. Their working principle is to directly resist seismic forces through high-strength materials. The rigid support forms a rigid connection with the wall. When seismic waves cause the wall to shift, the device cannot effectively absorb kinetic energy. Instead, it directly transmits the seismic energy to the support structure, resulting in local stress concentration. Due to the lack of a flexible energy dissipation mechanism, the device is prone to buckling deformation or weld tearing during strong earthquakes, reducing the device's service life. After an earthquake, the entire device needs to be replaced, and the cost of each maintenance is very high.

[0004] Therefore, a seismic protection device for building walls is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a seismic protection device for building walls to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: A seismic protection device for building walls includes a supporting base plate and a rotating plate. A rotating plate is installed on one side of the top of the supporting base plate via a rotating shaft. Two buffer grooves are opened inside the rotating plate. Two positioning components are slidably installed inside the buffer grooves. Energy-absorbing damping rods are fixed to both sides of the buffer grooves by bolts. One end of the energy-absorbing damping rod is fixedly connected to one side of the positioning component. An energy-absorbing support rod is slidably installed inside the positioning component. One end of the energy-absorbing support rod is connected to a seismic connecting plate by bolts. A first threaded groove is opened inside the seismic connecting plate. Two supporting sleeves are connected to one side of the rotating plate via a rotating shaft. A telescopic rod is slidably installed inside the supporting sleeve. An insert plate assembly is installed at one end of the telescopic rod via a rotating shaft. A fixing plate is provided on each side of the supporting base plate. Multiple fixing bolts are installed at equal intervals inside the fixing plate.

[0006] Preferably, the top of the support base plate is provided with a plurality of second limiting holes at equal intervals, and a second threaded groove is provided on both sides of the second limiting holes.

[0007] Preferably, the insert plate assembly includes an insert plate body, and a limiting plug is fixed at the bottom of the insert plate body. The insert plate body is limited to the second limiting hole, and the limiting plug is fixed to the second threaded groove by bolts.

[0008] Preferably, the positioning component includes a positioning block, and a limiting slide plate is welded to each side of the positioning block. A limiting slide groove is opened on the inner wall of the upper and lower sides of the buffer groove, and the limiting slide plate is slidably installed inside the limiting slide groove.

[0009] Preferably, one end of the energy-absorbing support rod slides through the interior of the positioning block, and a limit plate is welded to one end of the energy-absorbing support rod.

[0010] Preferably, a pressure plate is fixedly sleeved on the outer side of the energy-absorbing support rod, and an energy-absorbing spring is sleeved on the outer side of the energy-absorbing support rod. The energy-absorbing spring and the pressure plate are respectively located inside the positioning block, and the diameter of the pressure plate is larger than the diameter of the sliding hole between the energy-absorbing support rod and the positioning block.

[0011] Preferably, a plurality of first limiting holes are equally spaced on one side of the support sleeve, and a threaded bolt is connected to one side of the telescopic rod by thread engagement, wherein the threaded bolt is fitted with the first limiting holes.

[0012] Compared with the prior art, this utility model provides a seismic protection device for building walls, which has the following beneficial effects:

[0013] When an earthquake occurs, the wall will shift, and the pressure generated by this displacement will cause the seismic connection plate to move. This will cause multiple energy-absorbing support rods to expand and contract inside the positioning block. Since the outer side of the energy-absorbing support rod is fitted with a pressure plate and energy-absorbing spring, the energy-absorbing spring can absorb the pressure generated by the wall displacement. The energy-absorbing spring deforms under pressure, thus buffering and absorbing energy from the displaced wall while providing effective support and protection to prevent the wall from collapsing. When the wall undergoes longitudinal displacement, the kinetic energy generated by the longitudinal movement of the wall will be transferred to the seismic connection plate. When the seismic connection plate moves longitudinally, it will control the positioning block to slide inside the buffer groove. The energy-absorbing damping rod can absorb the kinetic energy of the positioning block's movement, thus ensuring that the wall does not collapse due to excessive longitudinal movement. This device can provide flexible seismic protection for the wall. When the wall undergoes lateral and longitudinal movement during an earthquake, it can absorb and dissipate the kinetic energy of the wall, thereby reducing the degree of deformation and damage to the device, increasing the service life of the device, and reducing maintenance costs.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: A rotating plate 7 is installed on one side of the top of the support base plate 1 via a rotating shaft. Two buffer grooves 15 are opened inside the rotating plate 7. Two positioning components 6 are slidably installed inside the buffer grooves 15. Energy-absorbing damping rods 14 are fixed to both sides of the buffer grooves 15 by bolts. One end of the energy-absorbing damping rod 14 is fixedly connected to one side of the positioning component 6. An energy-absorbing support rod 13 is slidably installed inside the positioning component 6. One end of the energy-absorbing support rod 13 is connected to the seismic connecting plate 5 by bolts. The seismic connecting plate 5 has a first threaded groove 4 inside. Two support sleeves 9 are connected to one side of the rotating plate 7 via a rotating shaft. A telescopic rod 11 is slidably installed inside the support sleeve 9. An insert plate assembly 12 is installed at one end of the telescopic rod 11 via a rotating shaft. A fixing plate 3 is provided on each side of the support base plate 1. Multiple fixing bolts 2 are installed at equal intervals inside the fixing plate 3.

[0022] The positioning component 6 includes a positioning block 601, and a limiting slide plate 602 is welded to each side of the positioning block 601. A limiting slide groove 1501 is opened on the inner wall of the upper and lower sides of the buffer groove 15. The limiting slide plate 602 is slidably installed inside the limiting slide groove 1501.

[0023] One end of the energy-absorbing support rod 13 slides through the interior of the positioning block 601, and a limit plate 1301 is welded to one end of the energy-absorbing support rod 13.

[0024] A pressure plate 1303 is fixedly sleeved on the outer side of the energy-absorbing support rod 13, and an energy-absorbing spring 1302 is sleeved on the outer side of the energy-absorbing support rod 13. The energy-absorbing spring 1302 and the pressure plate 1303 are respectively located inside the positioning block 601, and the diameter of the pressure plate 1303 is larger than the diameter of the sliding hole between the energy-absorbing support rod 13 and the positioning block 601.

[0025] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when providing seismic support and protection for the wall, the angle of connection with the wall is determined by rotating the rotating plate 7. Then, the insert plate assembly 12 is fixed to the top of the support base plate 1. The rotating plate 7 is supported by the support sleeve 9 and the telescopic rod 11. Since a seismic connecting plate 5 is installed on one side of the rotating plate 7 via multiple energy-absorbing support rods 13, and the seismic connecting plate 5 has multiple first threaded grooves 4 inside, it can be connected and fixed to the wall to be supported and protected using expansion bolts. When an earthquake occurs, the wall will displace, and the pressure generated by the wall displacement will cause the seismic connecting plate 5 to move. This will cause the multiple energy-absorbing support rods 13 to extend and retract inside the positioning block 601. Since a pressure plate 1303 and an energy-absorbing spring 1302 are sleeved on the outside of the energy-absorbing support rod 13, the energy-absorbing spring 1302 can absorb the pressure generated by the wall displacement. The energy-absorbing spring 1302 deforms under pressure, thereby buffering and absorbing energy from the displaced wall while providing effective support. This device provides protection against wall collapse. When the wall undergoes longitudinal displacement, the kinetic energy generated is transferred to the seismic connecting plate 5, and then to the positioning block 601 via the energy-absorbing support rod 13. Since the limiting slide plates 602 fixed on both sides of the positioning block 601 are slidably installed inside the limiting slide groove 1501, and the positioning block 601 is slidably installed inside the buffer groove 15, and one side of the positioning block 601 is fixedly connected to one end of an energy-absorbing damping rod 14, when the seismic connecting plate 5 moves longitudinally, it controls the positioning block 601 to slide within the buffer groove 15. Simultaneously, the energy-absorbing damping rod 14 absorbs the kinetic energy of the positioning block 601's movement, ensuring that the wall does not collapse due to excessive longitudinal movement. This device provides flexible seismic protection for the wall. When the wall experiences lateral and longitudinal movement during an earthquake, it absorbs and dissipates the wall's kinetic energy, thereby reducing the degree of deformation and damage to the device, increasing its service life, and lowering maintenance costs.

[0026] Example 2: The top of the support base plate 1 is provided with a plurality of second limiting holes 101 at equal intervals, and a second threaded groove 102 is provided on both sides of the second limiting holes 101. The insert plate assembly 12 includes an insert plate body 1202, and a limiting plug 1201 is fixed at the bottom of the insert plate body 1202. The insert plate body 1202 is limited to the second limiting holes 101, and the limiting plug 1201 is fixed to the second threaded groove 102 by bolts. A plurality of first limiting holes 10 are provided on one side of the support sleeve 9 at equal intervals, and a threaded plug 8 is connected to one side of the telescopic rod 11 by thread engagement. The threaded plug 8 is fitted with the first limiting holes 10.

[0027] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the total length of the support sleeve 9 and the telescopic rod 11 can be extended by pulling the telescopic rod 11, improving the flexibility of the device. Then, the support sleeve 9 and the telescopic rod 11 are locked and fixed by the threaded bolt 8. Then, the position of the limiting bolt 1201 is adjusted by rotating the insert plate body 1202 and the limiting bolt 1201 is inserted into the second limiting hole 101. Then, the insert plate assembly 12 is fixed to the top of the support base plate 1 by bolts passing through the limiting bolt 1201 and fixing it in the second threaded groove 102. Since there is a fixing plate 3 on each side of the support base plate 1, and multiple fixing bolts 2 are installed at equal intervals inside the fixing plate 3, the support base plate 1 can be fixed to the ground by fixing plate 3 and fixing bolts 2.

[0028] Working principle: During use, the support angle of the rotating plate 7 is adjusted according to the angle of the wall. Since an anti-seismic connecting plate 5 is installed on one side of the rotating plate 7 via multiple energy-absorbing support rods 13, and the anti-seismic connecting plate 5 has multiple first threaded grooves 4 inside, it can be connected and fixed to the wall to be supported and protected using expansion bolts. The supporting base plate 1 can be fixed to the ground via the fixing plate 3 and fixing bolts 2. When an earthquake occurs, the wall will shift, and the pressure generated by the wall displacement will cause the anti-seismic connecting plate 5 to move. This will cause the multiple energy-absorbing support rods 13 to expand and contract inside the positioning block 601. Since a pressure plate 1303 and an energy-absorbing spring 1302 are sleeved on the outside of the energy-absorbing support rods 13, the energy-absorbing spring 1302 can absorb the pressure generated by the wall displacement. The energy-absorbing spring 1302 expands and contracts under pressure. The deformation buffers and absorbs energy from the displaced wall, effectively supporting and protecting it to prevent collapse. Simultaneously, when the wall undergoes longitudinal displacement, the kinetic energy generated is transferred to the seismic connection plate 5, and then to the positioning block 601 via the energy-absorbing support rod 13. Since the limiting slide plates 602 fixed on both sides of the positioning block 601 are slidably installed inside the limiting slide groove 1501, and the positioning block 601 is slidably installed inside the buffer groove 15, and one side of the positioning block 601 is fixedly connected to one end of an energy-absorbing damping rod 14, when the seismic connection plate 5 moves longitudinally, it controls the positioning block 601 to slide inside the buffer groove 15. At the same time, the energy-absorbing damping rod 14 absorbs the kinetic energy of the moving positioning block 601, ensuring that the wall does not collapse due to excessive longitudinal movement.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
