Description

Technical Field

[0001] This utility model belongs to the field of seismic design technology in structural engineering, specifically relating to a self-resetting energy-dissipating buckling-resistant support device based on disc spring U-shaped damping components. Background Technology

[0002] Traditional seismic design methods rely on the failure of the main structure to dissipate seismic energy, resulting in significant residual deformation that renders the structure unusable or extremely difficult to repair after an earthquake. Energy dissipation and damping measures can effectively dissipate seismic energy, with buckling-restrained braces (BRs) being widely used in engineering practice as a good energy-dissipating component. However, their significant residual deformation greatly reduces their bracing performance.

[0003] The existing self-resetting energy dissipation supports mostly use prestressed tendons and shape memory alloys as the reset materials. Although both are excellent reset materials that can provide superior reset capabilities, prestressed tendons require prestressing, which places high demands on the anchoring system for applying prestress and makes construction more difficult. Shape memory alloys are expensive, which is not conducive to cost control, and they are affected by temperature, thus limiting their widespread application. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model application proposes a self-resetting energy-dissipating anti-buckling support device based on a disc spring U-shaped damping element, comprising: an outer sleeve, a left inner sleeve, a right inner sleeve, a support rod, and a disc spring assembly. The other ends of the left inner sleeve and the right inner sleeve are slidably connected by insertion. The outer sleeve is slidably connected to the outside of the left inner sleeve and the right inner sleeve. The disc spring assembly is slidably connected to the inside of the left inner sleeve and the right inner sleeve. The disc spring assembly is slidably fitted onto the support rod.

[0005] Preferably, an energy-consuming core rod is welded to one end of each of the left inner sleeve and the right inner sleeve.

[0006] Preferably, multiple limiting blocks are fixedly provided on the left and right sides of the inner side of the outer sleeve. The limiting blocks are used to limit the left and right positions of the disc spring assembly.

[0007] Preferably, the device further includes two limiting rings, which are slidably fitted on the support rod and are located on both sides of the disc spring assembly.

[0008] Preferably, a fixing part is welded to the outside of each limiting ring, and the fixing part is rotatably connected to one end of the connecting rod by bolts; the other end of each connecting rod is respectively hinged and rotatably connected to the inside of the corresponding right inner sleeve or left inner sleeve.

[0009] Preferably, the device further includes two U-shaped damping elements, which are fixedly connected to the inside of the outer sleeve. The two U-shaped damping elements are located on both sides of the left inner sleeve and the right inner sleeve, respectively, and are used to limit the movement of the two limiting rings.

[0010] This utility model also proposes an anti-seismic structure, including at least one self-resetting energy-dissipating buckling-resistance brace based on a disc spring U-shaped damping element. The two energy-dissipating core rods of the self-resetting energy-dissipating buckling-resistance brace based on the disc spring U-shaped damping element are respectively connected to the two parts requiring seismic resistance, thereby achieving seismic resistance between the two parts.

[0011] Compared with the closest existing technology, the beneficial effects of this utility model application are as follows:

[0012] By adjusting the positions of the left and right inner sleeves, the disc spring assembly can be appropriately compressed, giving it a certain preload in its initial state. This ensures that all parts are tightly connected and do not move relative to each other. This support device has better hysteresis energy dissipation capability, which can not only effectively protect the safety of the main structure, but also reduce or even eliminate residual deformation after the earthquake, ensuring that the structure can quickly restore its functionality after the earthquake. This is beneficial for cost control and results in relatively low processing costs. Attached Figure Description

Detailed Implementation

[0021] The specific embodiments of this utility model application will be further described in detail below with reference to the accompanying drawings.

[0022] Example:

[0023] like Figure 1-7 As shown, this utility model application proposes a self-resetting energy-dissipating anti-buckling support device based on a disc spring U-shaped damping element, including: an outer sleeve 2, a left inner sleeve 3, a right inner sleeve 4, a support rod 6, and a disc spring assembly 7. The other end of the left inner sleeve 3 and the other end of the right inner sleeve 4 are inserted and slidably connected. The outer sleeve 2 is slidably connected to the outside of the left inner sleeve 3 and the right inner sleeve 4. The disc spring assembly 7 is slidably connected to the inside of the left inner sleeve 3 and the right inner sleeve 4. The disc spring assembly 7 is slidably fitted on the support rod 6.

[0024] Furthermore, an energy-consuming core rod 1 is welded to one end of each of the left inner sleeve 3 and the right inner sleeve 4.

[0025] As mentioned above, each of the left inner sleeve 3 and right inner sleeve 4 has a connection hole at one end where it connects to the energy-consuming core rod 1. The energy-consuming core rod 1 is then inserted into the connection hole and welded in place.

[0026] Furthermore, multiple limiting blocks 8 are fixedly installed on the left and right sides of the inner side of the outer sleeve 2. The limiting blocks 8 are used to limit the left and right positions of the left inner sleeve 3 and the right inner sleeve 4 during earthquakes, and to prevent the U-shaped damping element 5 from being impacted by the sleeve. There can be four limiting blocks 8.

[0027] As described above, the outer sleeve 2 is a rectangular cubic structure, formed by splicing. During assembly, the side plates on both sides of the outer sleeve 2 are assembled using a splicing method. The energy-dissipating core rod 1 extends out of the outer sleeve 2 and is slidably connected to it.

[0028] As mentioned above, the left inner sleeve 3 and the right inner sleeve 4 can also be set as a cubic structure, which can effectively prevent the left inner sleeve 3 and the right inner sleeve 4 from rotating relative to the outer sleeve 2, so that the left inner sleeve 3 and the right inner sleeve 4 can slide inside the outer sleeve 2 and cannot rotate.

[0029] Furthermore, the device also includes two limiting rings 9, which are slidably fitted onto the support rod 6 and are located on both sides of the disc spring assembly 7. The outer diameter of the limiting ring 9 is larger than the inner diameter of the disc spring assembly 7, and is used to limit the movement of the disc spring assembly 7.

[0030] Furthermore, each of the limiting rings 9 is externally welded with a fixing part 12, and the fixing part 12 is rotatably connected to one end of the connecting rod 10 by bolts; the other end of each connecting rod 10 is respectively hinged and rotatably connected to the inside of the corresponding right inner sleeve 4 or left inner sleeve 3.

[0031] As mentioned above, the limiting ring 9 is a hollow circle, and two connecting rods 10 can be hinged and rotatably connected to the outside of each limiting ring 9. The two connecting rods 10 are symmetrically distributed on the circumference of the limiting ring 9.

[0032] Furthermore, the device also includes two U-shaped damping elements 5, which are fixedly connected to the inside of the outer sleeve 2. The two U-shaped damping elements 5 are located on either side of the left inner sleeve 3 and the right inner sleeve 4, respectively, and are used to limit the movement of the two limiting rings 9. The U-shaped damping elements 5 have a U-shaped structure. When the disc spring assembly 7 is compressed, the left inner sleeve 3 and the right inner sleeve 4 move, and the two U-shaped damping elements 5 deform, thus dissipating energy. By adjusting the positions of the left inner sleeve 3 and the right inner sleeve 4, the disc spring assembly 7 can be compressed, applying a certain prestress to the disc spring assembly 7. The two energy-dissipating core rods 1 are welded to the outer sides of the side plates of the left inner sleeve 3 and the right inner sleeve 4, respectively. The movement of the two energy-dissipating core rods 1 drives the movement of the left inner sleeve 3 and the right inner sleeve 4.

[0033] As described above, the disc spring assembly 7 is slidably mounted on the support rod 6 in a combination of multiple disc springs. The limiting ring 9 is located at both ends of the disc spring assembly 7. By adjusting the positions of the left inner sleeve 3 and the right inner sleeve 4, the disc spring assembly 7 can be appropriately compressed so that the disc spring assembly 7 has a certain preload in the initial state, ensuring that its parts are tightly connected and will not move relative to each other. A single energy-dissipating core rod 1 is welded to the outer side of the end face of the left inner sleeve 3 and the right inner sleeve 4. The two energy-dissipating core rods 1 are used to connect to the required connection positions respectively.

[0034] Example 2:

[0035] This utility model also proposes an anti-seismic structure, including at least one self-resetting energy-dissipating buckling-resistance brace based on a disc spring U-shaped damping element. The two energy-dissipating core rods of the self-resetting energy-dissipating buckling-resistance brace based on the disc spring U-shaped damping element are respectively connected to the two parts requiring seismic resistance, thereby achieving seismic resistance between the two parts.

[0036] A specific use case is provided: During an earthquake, the two parts undergo relative changes, causing the support device to be subjected to reciprocating cyclic loads. The energy-dissipating core rod 1 moves relative to or away from each other. The movement of the energy-dissipating core rod 1 drives the left inner sleeve 3 and the right inner sleeve 4 to move. The connecting rod 10 pushes the limiting ring 9, which then compresses the disc spring assembly 7 to generate deformation, providing the support device with a restoring force and a certain frictional energy dissipation capacity. At this time, the U-shaped damping element 5 deforms to fully utilize its energy dissipation capacity.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model application and not to limit its protection scope. Although the utility model application has been described in detail with reference to the above embodiments, those skilled in the art should understand that after reading this utility model application, they can still make various changes, modifications or equivalent substitutions to the specific implementation of the application.
