[0002] As the construction industry's requirements for energy conservation, environmental protection and construction efficiency continue to increase, prefabricated buildings have gradually become an important development trend. Prefabricated buildings can significantly increase construction speed and reduce the complexity and labor demand of on-site construction through on-site assembly of prefabricated components. However, the structural characteristics of prefabricated buildings are different from those of traditional buildings and may face some unique challenges, especially in terms of earthquake resistance.

[0003] Prefabricated components of prefabricated buildings are usually connected by connectors (such as bolts, steel bars, etc.). The strength and rigidity of these connectors are crucial to the overall earthquake resistance of the building. However, since the rigidity of these connectors may be insufficient, the building may experience large vibrations under external shocks such as earthquakes, thereby increasing the risk of building damage. In particular, prefabricated components such as columns or walls that play a supporting role, if the bottom position is unstable after assembly, will cause the prefabricated components to shake greatly when there is a large external vibration and be damaged, affecting the overall stability of the prefabricated building.

[0004] Therefore, it is necessary to provide an improved technical solution to address the above-mentioned deficiencies in the prior art. Summary of the invention

[0014] As a further optimized technical solution, the support reinforcement member is a support rod, which is arranged obliquely, with one end of the support rod pressing against the first connecting member and the other end pressing against the outer wall of the prefabricated component.

[0015] As a further optimized technical solution, the support rods are arranged in multiple groups along the height extension direction of the prefabricated component, and the angle between the support rods and the prefabricated component gradually decreases from top to bottom.

[0026] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention belong to the scope of protection of the present invention.

They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention. The terms "connected" and "connected" used in the present invention should be understood in a broad sense. For example, they can be fixed connections or detachable connections; they can be directly connected or indirectly connected through intermediate components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0028] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0029] The shapes and sizes of the components in the drawings do not reflect the actual proportions of the products, and are only intended to illustrate the contents of the present invention.

[0030] Prefabricated components of prefabricated buildings are usually connected by connectors (such as bolts, steel bars, etc.). The strength and stiffness of these connectors are crucial to the overall earthquake resistance of the building. However, since the stiffness of these connectors may be insufficient, the building may vibrate greatly under external shocks such as earthquakes, thereby increasing the risk of building damage. In particular, prefabricated components such as columns or walls, if the bottom position is not connected stably after assembly, will cause the prefabricated components to shake greatly as a whole when large vibrations occur, resulting in damage.

[0031] In order to solve the above technical problems, the present invention proposes a shock absorbing device for prefabricated components of an assembled building, which reduces the shaking amplitude of the prefabricated components in the horizontal direction by setting a buffer groove and a flexible buffer material as a buffer structure in the prefabricated components, thereby ensuring the overall stability of the assembled building. The device is specifically described below by using a column as a specific embodiment.

[0032] Example 1

[0033] like Figure 1 , Figure 2 As shown, the shock absorbing device of the prefabricated components of the assembled building includes a first connecting member 2 fixedly arranged on the top of the supporting platform 1, a buffer groove 3 fixedly arranged on the first connecting member 2, a second connecting member 4 for connecting the prefabricated component 6 and the first connecting member 2, and a flexible buffer material 5 filled in the buffer groove 3.

[0034] The first connecting member 2 has a supporting top surface 201 for supporting the prefabricated component 6, so as to facilitate connection with the prefabricated component 6. In this embodiment, the first connecting member 2 includes a connecting plate 202 and an anchoring rib 203, one end of the anchoring rib 203 is fixedly connected to the connecting plate 202 by welding, and the other end extends to a side away from the connecting plate 202, and the side of the connecting plate 202 away from the anchoring rib 203 constitutes the above-mentioned supporting top surface 201. Specifically, a groove whose shape is adapted to the connecting plate 202 is provided on the top of the supporting platform 1, and the first connecting member 2 is arranged in the groove and cast integrally with the supporting platform 1. In this way, the supporting top surface 201 of the first connecting member 2 is flush with the top surface of the supporting platform 1, so as to facilitate the installation of the prefabricated component 6.

[0035] The buffer groove 3 is open at the top, and its bottom is fixedly arranged on the supporting top surface 201 . The side wall of the buffer groove 3 and the supporting top surface 201 enclose a storage space for containing the flexible buffer material 5 .

[0036] The second connecting member 4 is a connecting groove 401 including an opening toward the prefabricated component 6, the bottom of the connecting groove 401 is fixedly connected to the first connecting member 2, a sliding block 402 is slidably arranged in the connecting groove 401, the top of the sliding block 402 is fixedly connected to the prefabricated component 6, and an elastic buffer component 403 is arranged at intervals in the circumference of the sliding block 402, one end of the elastic buffer component 403 presses against the sliding block 402, and the other end presses against the side wall of the connecting groove 401. With this design, the prefabricated component 6 and the supporting platform 1 can adapt to a certain displacement, and the first connecting member 2 and the second connecting member 4 can allow the prefabricated component 6 and the supporting platform 1 to have relative displacement within a certain range, while maintaining the connection force, avoiding stress concentration and premature damage caused by rigid connection. The elastic buffer component 403 can allow a certain degree of relative deformation during an earthquake, absorb and dissipate earthquake energy, and reduce stress concentration at the connection part. At the same time, the elastic buffer component 403 can also compensate for the slight displacement of the prefabricated component 6, avoiding damage to the prefabricated component 6 caused by rigid connection.

[0037] Furthermore, in order to ensure the stability of the installation of the prefabricated component 6 , the cross-sectional dimension of the sliding block 402 is larger than the cross-sectional dimension of the prefabricated component 6 , and the prefabricated component 6 is fixedly connected to the middle of the sliding block 402 .

[0038] The flexible buffer material 5 is filled between the inner wall of the buffer groove 3 and the prefabricated component 6 to reduce the shaking amplitude of the prefabricated component 6. In addition, the prefabricated component 6 is arranged in the middle of the buffer groove 3 during installation, so that the buffering force of the flexible buffer material 5 on the prefabricated component 6 can be balanced, which is more conducive to maintaining balance with the prefabricated component 6 during horizontal shaking.

[0039] In the present invention, the flexible buffer material 5 can be made of rubber particles, rubber foam particles, cork materials combined with polyurethane adhesives to form particles, which not only have good buffering performance, but also have the characteristics of light weight and environmental protection. In other embodiments, the flexible buffer material 5 can also use rubber modified by nanomaterials or new high-performance polymer foam materials. These materials may have better energy absorption and recovery performance, and can more effectively reduce the shaking amplitude of the prefabricated component 6. For example, the addition of nanomaterials may enhance the strength and toughness of the rubber, so that it can still maintain a good buffering effect after multiple deformations.

[0040] Furthermore, the flexible buffer material 5 is arranged in layers, and the hardness of the layered flexible buffer material 5 gradually increases from top to bottom. The layered flexible buffer material 5 can be arranged in different densities to achieve different hardnesses required for different layers, or different materials can be selected for different layers, depending on the actual situation.

[0041] The layered arrangement of the flexible buffer material 5 can make the prefabricated component 6 have a suitable buffer response under different shaking amplitudes. Because the shaking amplitude of the prefabricated component 6 will increase with the increase of height under the condition of horizontal earthquake damage energy, the hardness of the lower layer of flexible buffer material 5 is set higher than that of the upper layer, so that the lower layer of flexible buffer material 5 can further ensure the stability of the prefabricated component 6 while buffering energy. The upper layer of relatively soft flexible buffer material 5 is more conducive to buffering the deformation of the prefabricated component 6.

[0042] In this embodiment, the flexible buffer material 5 is provided with two layers, namely a buffer layer 501 and a stabilization layer 502 arranged from top to bottom. The buffer layer 501 and the stabilization layer 502 are made of the same material, but the stabilization layer 502 is arranged more tightly during processing, so its density is greater than that of the buffer layer 501.

[0043] Furthermore, the top surface of the stabilizing layer 502 is inclined and gradually tilts downward from the side close to the prefabricated component 6 to the side away from the prefabricated component 6. In this way, the width of the buffer layer 501 gradually decreases from top to bottom, and the width of the stabilizing layer 502 gradually increases from top to bottom. The buffer layer 501 can better achieve a buffering response to the prefabricated component 6, and the stabilizing layer 502 can also better play a stabilizing supporting role for the prefabricated component 6.

[0044] Furthermore, the shock absorbing device of the prefabricated component of the assembled building also includes a supporting reinforcement 7, which is arranged in the buffer groove 3 and circumferentially around the prefabricated component 6, so as to further support the prefabricated component 6.

[0045] In this embodiment, the support reinforcement member 7 is a support rod, which is tilted, one end of the support rod is pressed against the first connecting member 2 and welded to the first connecting member 2, and the other end is pressed against the outer wall of the prefabricated component 6. In this way, the flexible buffer material 5 in the buffer groove 3 and the support reinforcement member 7 work together to further reduce the damage to the prefabricated component 6 caused by the vibration in the horizontal direction. Moreover, under normal circumstances, although the prefabricated component 6 is not rigidly connected to the supporting platform 1, it can still remain stable under the action of the support reinforcement member 7. When it is subjected to a huge earthquake energy impact, the prefabricated component 6 is slightly displaced in the connecting groove 401 through the sliding block 402 to remove excessive destructive energy, thereby avoiding stress concentration at the bottom end of the prefabricated component 6 and causing damage. In this process, the support reinforcement member 7 is slightly deformed to adapt to the displacement of the prefabricated component 6.

[0046] Furthermore, the support rods are arranged in multiple groups along the height extension direction of the prefabricated component 6, as shown in FIG. Figure 2 As shown, the angle between the support rod and the prefabricated component 6 gradually decreases from top to bottom. That is, the support rod is arranged in multiple layers in the buffer groove 3 to fully support the prefabricated component 6.

[0047] In this embodiment, in order to further buffer and absorb the deformation energy of the prefabricated component 6, the groove wall of the buffer groove 3 is made of high-strength rubber material. High-strength rubber refers to the rubber required for products such as tires that withstand high-strength forces. It has elastic buffering deformation capabilities and certain supporting performance.

[0048] In order to ensure the shape stability of the buffer groove 3 , a fixing component 8 for supporting the groove wall of the buffer groove 3 is vertically arranged on the first connecting member 2 to fully support the buffer groove 3 .

[0049] Furthermore, the fixing component 8 is a stop rod arranged at intervals outside the buffer groove 3, the bottom end of the stop rod is fixedly connected to the first connecting member 2, and the upper part extends upward and supports the buffer groove 3 to reduce deformation of the buffer groove 3.

[0050] When the above-mentioned device is in use, when a large external impact such as an earthquake occurs, the prefabricated component 6 is prone to a large degree of horizontal shaking. By providing the buffer groove 3, the flexible buffer material 5 and the supporting reinforcement 7 in the buffer groove 3 can fully absorb the deformation energy of the prefabricated component 6, and fully support the prefabricated component 6 with "softness and hardness", thereby ensuring the connection strength of the prefabricated component 6, improving the overall seismic resistance of the prefabricated building, and then ensuring the overall stability of the prefabricated building.

[0051] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
