Description

Technical Field

[0001] The invention relates to the technical field of steel grids, in particular to a steel grid composite damping shock-absorbing support and a preparation method thereof. Background Art

[0002] Steel grid damping shock-absorbing bearings, as a key component, are widely used in various building structures to absorb and dissipate vibration energy, thereby protecting buildings from natural disasters such as earthquakes; however, the steel grid damping shock-absorbing bearings in the prior art face several limitations in practical applications, which affect their long-term performance and maintenance costs.

[0003] First, traditionally, this type of damping and shock-absorbing bearings are mostly fixed and installed by expansion screws. Although this installation method is simple and direct, it brings inconvenience in subsequent maintenance and replacement. Once the material needs to be repaired or replaced due to aging, fatigue or other reasons, the removal and reinstallation process will become extremely complicated and time-consuming and labor-intensive, which not only increases maintenance costs, but may also have an adverse effect on the overall performance of the structure; secondly, current steel grid damping and shock-absorbing bearings generally exhibit limited elastic deformation capacity, which means that when faced with large or frequent external forces, these materials may not be able to fully and effectively absorb and dissipate vibration energy, which in turn leads to potential threats to the safety and durability of the structure. Therefore, we proposed a steel grid composite damping and shock-absorbing bearing and a preparation method thereof. Summary of the invention

[0043] S6. Final inspection and adjustment: After completing the above steps, conduct a comprehensive inspection of the entire steel grid damping and shock absorption system to confirm that all components have been correctly installed and are not loose. If necessary, make fine adjustments, paying special attention to checking whether the functions of the easy-to-disassemble mechanism 4, the damping and shock absorption mechanism 5 and the quick-change structure 6 are normal, to ensure that the stability and shock absorption performance of the system are in the best state.

[0044] Embodiment 1:

[0045] When the steel grid is vibrated, the vibration is transmitted to the grid rod 505, and then to the installation sleeve 504; the damping shock absorbing mechanism 5 starts to work, and the damping shock absorbing plate 501 will be displaced under the action of vibration, driving the spring damper 502 and the rubber shock absorbing block 503 to deform; the spring damper 502 uses its own elasticity and damping characteristics to convert the vibration energy into other forms of energy such as heat energy for dissipation, and at the same time provides a certain elastic supporting force; the rubber shock absorbing block 503, with its good elasticity and flexibility, further absorbs and disperses the vibration energy, reduces the impact of vibration on the grid structure, and protects the safety of the building.

[0046] During maintenance, if the entire damping and shock absorbing box 412 needs to be disassembled, maintained or replaced, the disassembly mechanism 4 is operated; by rotating the threaded control rod 407, due to the threaded connection between the threaded plate 406 and the threaded control rod 407, the rotation of the threaded control rod 407 will drive the clamping plate 404 to slide along the slide rod 403; when the clamping plate 404 slides in the direction away from the fixed plug cylinder 408, the clamping plug rod 405 is disengaged from the fixed plug block 410, and the damping and shock absorbing box 412 can be taken out of the fixed plug cylinder 408 together with the connecting plate 411 and the fixed plug block 410 to complete the overall disassembly; during installation, the threaded control rod 407 is operated in reverse to make the clamping plate 404 slide in the direction of the fixed plug cylinder 408 until the clamping plug rod 405 is reinserted into the fixed plug block 410, so as to achieve rapid installation of the damping and shock absorbing box 412.

[0047] If only one of the damping and shock absorbing plate 501, the spring damper 502 or the rubber shock absorbing block 503 has a problem and needs to be replaced, use the quick replacement structure 6; first remove the sealing cover plate 413, then pull out the limit pin 607, pull the damping and shock absorbing plate 501 outward, separate the spring damper 502 from the first limit socket 605, separate the rubber shock absorbing block 503 from the second limit socket 608, and take the damping and shock absorbing plate 501 out of the damping and shock absorbing box 412 for replacement; after replacement, install it in the reverse order to ensure that the two sides of the damping and shock absorbing plate 501 are smoothly slidably connected to the connecting slide bar 604, and the connecting plug 606 at the bottom of the spring damper 502 is accurately inserted into the first limit socket 605, and the limit pin 607 is inserted to fix it.

[0048] Embodiment 2:

[0049] The spring damper 502 mainly works based on the elastic characteristics of the spring and the energy dissipation characteristics of the damper; when the building is vibrated, the vibration is transmitted to the damping plate 501, and then the spring damper 502 is acted upon by a force; the spring will undergo elastic deformation when subjected to force, converting the kinetic energy of the vibration into its own elastic potential energy and storing it; when the vibration force weakens, the elastic potential energy will be released again. It is through the synergistic effect of the spring storing energy and the damper dissipating energy that the spring damper 502 can effectively absorb and consume a large amount of vibration energy during the vibration process, reduce the impact of the vibration on the steel grid structure, and ensure the safety of the building.

[0050] The rubber shock-absorbing block 503 utilizes the high elasticity and viscoelasticity of the rubber material itself to achieve shock absorption; there is a weak interaction force between the rubber molecular chains, which enables the rubber to undergo a large elastic deformation when subjected to an external force; when the vibration is transmitted to the rubber shock-absorbing block 503, the relative sliding and friction between the rubber molecular chains will convert the vibration energy into heat energy; the viscoelasticity of the rubber makes it both elastic and viscous during the deformation process, the elastic part enables the rubber to store and release part of the energy like a spring, while the viscous part is similar to a damper, dissipating the energy in the form of heat; in addition, the rubber also has good flexibility and plasticity, can adapt to vibrations of different directions and forms, and absorb and disperse vibration energy in all directions, further enhancing the shock absorption effect of the entire damping shock absorbing mechanism 5.

[0051] The spring damper 502 and the rubber shock absorbing block 503 complement each other. The spring damper 502 is good at playing a role in larger vibrations. Through the cooperation of the spring and the damper, it can efficiently handle medium and high intensity vibration energy; the rubber shock absorbing block 503, with its flexibility and viscoelasticity, performs well in dealing with complex directions and small vibrations, and can capture and consume those subtle vibration energies that are difficult for the spring damper to handle. The two work together to greatly improve the overall shock absorbing effect; the quick replacement structure 6 ensures that the relevant components can be replaced quickly and individually.

[0052] In summary, the steel grid composite damping shock-absorbing support and the preparation method thereof, by designing an easy-to-disassemble mechanism 4, make the installation and maintenance of the damping shock-absorbing composite material simple and quick. The clamping plate 404 slides in the limiting cavity 402 through the sliding rod 403, and can easily clamp or release the damping shock-absorbing box 412 with the damping shock-absorbing mechanism 5 and the quick-change structure 6 installed on the top. This design can complete the installation and disassembly without complicated tools or steps, effectively reducing maintenance time, reducing maintenance costs, and improving the reliability and durability of the system.

[0053] Moreover, the steel grid composite damping shock-absorbing support and the preparation method thereof, through the damping shock-absorbing mechanism 5 composed of the damping shock-absorbing plate 501, the spring damper 502 and the rubber shock-absorbing block 503, when encountering vibration, the spring damper 502 and the rubber shock-absorbing block 503 work together to provide good elastic deformation ability, thereby effectively absorbing and dissipating vibration energy; in addition, the quick replacement structure 6 ensures that the damping shock-absorbing plate 501, the spring damper 502 and the rubber shock-absorbing block 503 can be replaced quickly and individually, further enhancing the stability and shock-absorbing performance of the system, ensuring the safety and durability of the building, and solving the problem that traditional damping shock-absorbing supports are mostly fixed by expansion screws, resulting in complicated and time-consuming subsequent maintenance and replacement processes, and failing to fully absorb and dissipate vibration energy, affecting the safety and durability of the structure.
