Description

Technical Field

[0001] This invention relates to the field of precast wall panel damping technology, specifically to an integrated damping device for precast wall panels. Background Technology

[0002] Against the backdrop of the rapid development of prefabricated buildings, prefabricated wall panels, as an important component of the building structure, directly affect the overall safety and durability of the building due to their seismic performance. They are also crucial for ensuring structural stability and reducing casualties and property damage during sudden disasters such as earthquakes. As prefabricated buildings move towards higher-rise and larger-scale construction, the size and weight of prefabricated wall panels are constantly increasing, leading to higher requirements for seismic protection at their connection points.

[0003] However, traditional viscous dampers have significant technical limitations. They are mainly used to reduce the lateral impact force generated by earthquakes, but lack effective countermeasures for the vertical impact force caused by earthquakes, which makes the wall panels prone to structural deformation during longitudinal vibration.

[0004] Therefore, a new integrated damping device for prefabricated wall panels is provided to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated damping device for prefabricated wall panels to solve the aforementioned problems. The longitudinal damping component reduces the vertical impact force generated on the wall panel during an earthquake, alleviating the problem that traditional adhesive dampers can only reduce lateral impact forces. Simultaneously, the auxiliary damping component can mitigate the phenomenon of localized tension caused by large lateral impact forces during an earthquake.

[0006] The present invention achieves the above-mentioned objective through the following technical solution: a prefabricated wall panel integrated damping device, comprising a first steel wall panel, a second steel wall panel, and an adhesive damper body, further comprising a longitudinal damping component and an auxiliary damping component, wherein the adhesive damper body is installed between the first steel wall panel and the second steel wall panel, the longitudinal damping component is disposed between the first steel wall panel and the second steel wall panel, and the auxiliary damping component is installed between the adhesive damper body and the first steel wall panel.

[0007] Preferably, when the wall panel is subjected to vertical impact forces from factors such as earthquakes, the inclined connecting column can utilize its own inclined structural characteristics to decompose part of the vertical impact force into a component force along the length of the connecting column. This component force can be absorbed and buffered through the elastic deformation of the connecting column itself or in cooperation with other components, effectively reducing the impact of vertical vibration on the overall structure of the wall panel. The longitudinal damping component includes the connecting column, and a first groove is provided on the outside of the first steel wall panel, with a guide rod fixedly installed inside the groove.

[0008] Preferably, the first steel wall panel and the second steel wall panel will have relative vertical displacement. At this time, the connecting column will drive the slider to slide along the guide rod. During the sliding process, the slider will compress or stretch the torsion springs on both sides. The elastic restoring force of the torsion spring can effectively buffer this vertical impact force, thereby achieving the effect of longitudinal damping. Torsion springs are sleeved on the left and right sides of the guide rod, and a slider slides on the outside of the slide rod. A first concave block is fixedly installed on the outside of the slider.

[0009] Preferably, when the wall panel undergoes longitudinal displacement due to vibration, the slider slides along the guide rod. At this time, the torsion springs on the left and right sides undergo elastic deformation due to the compression or stretching of the slider, thereby converting some of the vibration energy into elastic potential energy, effectively slowing down the slider's movement speed and impact force, and thus reducing the relative vibration amplitude between the first steel wall panel and the second steel wall panel, so that the slider is located between the torsion springs. The upper part of the second steel wall panel is provided with a second sliding groove, which corresponds to the first sliding groove. A lead screw is rotatably connected inside the second sliding groove.

[0010] Preferably, the lead screw can drive the moving block to move when it rotates. As the moving block moves, it drives the second concave block to move synchronously. As the second concave block moves, the angle of the connecting column changes, thereby adjusting the buffer amplitude as needed. The moving block is screwed to the outside of the lead screw, and the second concave block is fixedly installed on the outside of the moving block. The upper part of the connecting column is rotatably connected to the second concave block, and the lower part of the connecting column is rotatably connected to the first concave block.

[0011] Preferably, the circular knob requires a flathead screwdriver to turn. The screwdriver is inserted into the flathead groove to rotate the circular knob, thereby driving the lead screw to rotate. This avoids accidental changes in the buffer parameters due to accidental touch or arbitrary adjustment by non-professionals, ensuring the stability and reliability of the buffer mechanism's working state. The circular knob is inserted inside the second steel wall panel, and the outside of the circular knob is fixedly connected to one end of the lead screw. The outside of the circular knob has a flathead groove.

[0012] Preferably, the connecting pin seat and the mounting plate are both fixed by bolts. The auxiliary damping component includes a connecting pin seat, which is externally fixedly connected to the first steel wall plate and externally fixedly connected to the adhesive damper body. The mounting plate is externally fixedly installed on the second steel wall plate, and the movable end of the adhesive damper body is externally hinged to the mounting plate.

[0013] Preferably, the screw, once tightened, secures the connecting side plate. After the connecting side plate is fixed, the L-shaped rod provides secondary restraint to the wall panel, thereby mitigating the localized pulling phenomenon caused by the large lateral impact force during an earthquake. The L-shaped rod is fixedly installed on the outside of the mounting plate, and the connecting side plate is fixedly installed between the L-shaped rods. The connecting side plate has a threaded groove inside, and a screw is screwed into the threaded groove. One end of the screw abuts against the outside of the second steel wall panel.

[0014] The beneficial effects of this invention are:

[0015] 1. The longitudinal damping component is designed to adapt to different longitudinal impact buffering requirements, thereby alleviating the problem that traditional viscous dampers are mainly used to reduce the lateral impact force generated by earthquakes, but lack effective measures to deal with the vertical impact force caused by earthquakes.

[0016] 2. The auxiliary damping component, working in conjunction with the longitudinal damping component, achieves dual vibration reduction effects in both the longitudinal and lateral directions. This overcomes the limitation of traditional adhesive dampers, which can only reduce lateral impact forces, and enhances the seismic performance of precast wall panels. This device has a compact structure and is easy to install, meeting the requirements for integrated installation of precast wall panels. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-6 As shown, a prefabricated wall panel integrated damping device includes a first steel wall panel 1, a second steel wall panel 4, and an adhesive damper body 5. It also includes a longitudinal damping component 2 and an auxiliary damping component 3. The adhesive damper body 5 is installed between the first steel wall panel 1 and the second steel wall panel 4. The longitudinal damping component 2 is located between the first steel wall panel 1 and the second steel wall panel 4. The auxiliary damping component 3 is installed between the adhesive damper body 5 and the first steel wall panel 1. The longitudinal damping component 2 reduces the vertical impact force generated by the wall panel during an earthquake, solving the problem that traditional adhesive dampers can only reduce lateral impact forces. Simultaneously, the auxiliary damping component can alleviate the phenomenon of localized tension caused by large lateral impact forces generated during an earthquake.

[0026] like Figures 1-6As shown, the longitudinal damping assembly 2 includes a connecting column 201. A first groove 202 is formed on the outside of the first steel wall panel 1. A guide rod 203 is fixedly installed inside the groove. Torsion springs 204 are sleeved on the left and right sides of the guide rod 203. A slider 205 slides on the outside of the guide rod 203. A first concave block 206 is fixedly installed on the outside of the slider 205, and the slider 205 is located between the torsion springs 204. A second groove is formed on the upper part of the second steel wall panel 4, corresponding to the first groove 202. A lead screw 207 is rotatably connected inside the second groove. A moving block 208 is screwed onto the outside of the lead screw 207. A moving block 208 is fixedly installed on the outside of the moving block 208. The upper part of the connecting column 201 is rotatably connected to the second concave block, and the lower part of the connecting column 201 is rotatably connected to the first concave block 206. A circular knob 209 is inserted inside the second steel wall plate 4. The outside of the circular knob 209 is fixedly connected to one end of the screw rod 207. A flat groove is opened on the outside of the circular knob 209. When an earthquake occurs, the first steel wall plate 1 is squeezed and moves, which in turn drives the second concave block to move synchronously. As the second concave block moves, it drives the connecting column 201 rotatably connected to it to move. When the connecting column 201 moves, it further drives the first concave block 206 rotatably connected to the lower part to move. Finally, during the process of the first concave block 206 driving the slider 205 to slide along the guide rod 203, the torsion springs 204 set on both sides of the guide rod 203 deform, effectively buffering the movement of the slider 205, thereby offsetting the longitudinal impact force. When it is necessary to adjust the range of motion and installation angle of the device, a flathead screwdriver is used to turn the circular knob 209, which drives the lead screw 207 to rotate. The rotation of the lead screw 207 drives the moving block 208 and the second concave block to move, thereby adjusting the tilt angle of the connecting column 201 to adapt to the longitudinal impact buffering requirements of different ranges. This alleviates the problem that traditional viscous dampers are mainly used to reduce the lateral impact force generated by earthquakes, and lack effective countermeasures for the vertical impact force caused by earthquakes.

[0027] like Figures 1-6As shown, the auxiliary damping assembly 3 includes a connecting pin seat 301, which is fixedly connected to the outside of the first steel wall plate 1 and to the outside of the adhesive damper body 5. An mounting plate 302 is fixedly installed on the outside of the second steel wall plate 4. The movable end of the adhesive damper body 5 is hinged to the outside of the mounting plate 302. An L-shaped rod 303 is fixedly installed on the outside of the mounting plate 302. A connecting side plate 304 is fixedly installed between the L-shaped rods 303. A threaded groove is provided inside the connecting side plate 304, and a screw 305 is screwed into the threaded groove. One end of the screw 305 abuts against the second steel wall plate 4. On the outside of panel 4, auxiliary damping component 3 fixes the adhesive damper body 5 to the connecting pin seat 301 and mounting plate 302 to ensure its stable installation. Tighten the screw 305 on the connecting side plate 304 to fix the connecting side plate 304. L-shaped rod 303 provides secondary limit for the wall panel to alleviate the local tension caused by excessive lateral impact force during earthquakes. The longitudinal damping component 2 works with the auxiliary damping component 3 to achieve dual longitudinal and lateral shock reduction, solving the drawback of traditional adhesive dampers that can only reduce lateral impact force, improving the seismic performance of precast wall panels. It has a compact structure, is easy to install, and is suitable for the integrated installation requirements of precast wall panels.

[0028] When the invention is in use, during the operation of the overall device, the adhesive damper body 5 is mainly used to reduce the lateral impact force between the first steel wall plate 1 and the second steel wall plate 4. The longitudinal damping component 2 achieves longitudinal shock absorption through the inclined connecting column 201 and the torsion spring 204. When an earthquake occurs, the first steel wall plate 1 is compressed and moves, which in turn drives the second concave block to move synchronously. As the second concave block moves, it drives the connecting column 201 rotatably connected to it to move. When the connecting column 201 moves, it further drives the first concave block 206 rotatably connected to the lower part to move. Finally, as the first concave block 206 drives the slider 205 to slide along the guide rod 203, the torsion springs 204 set on both sides of the guide rod 203 deform, effectively buffering the movement of the slider 205, thereby offsetting the longitudinal impact force.

[0029] When it is necessary to adjust the range of motion and installation angle of the device, a flathead screwdriver is used to turn the round knob 209, which drives the lead screw 207 to rotate. The rotation of the lead screw 207 drives the moving block 208 and the second concave block to move, thereby adjusting the tilt angle of the connecting column 201 to adapt to the longitudinal impact buffering requirements of different amplitudes.

[0030] The auxiliary damping component 3 fixes the adhesive damper body 5 to the connecting pin seat 301 and the mounting plate 302 to ensure its stable installation. Tightening the screw 305 on the connecting side plate 304 fixes the connecting side plate 304. The L-shaped rod 303 provides secondary restraint for the wall panel, alleviating the local tension caused by excessive lateral impact force during an earthquake. The longitudinal damping component 2 and the auxiliary damping component 3 work together to achieve dual longitudinal and lateral shock reduction, solving the drawback of traditional adhesive dampers that can only reduce lateral impact force, and improving the seismic performance of precast wall panels. The device has a compact structure, is easy to install, and can adapt to the integrated installation requirements of precast wall panels.
