Description

Technical Field

[0001] The invention relates to a shock absorbing device, in particular to an anti-buckling support. Background Art

[0002] With the continuous advancement of technology, buckling-resistance braces (BRs) are increasingly used in civil engineering. They are primarily used as energy-dissipating and vibration-absorbing devices in the lateral force resistance systems of multi-story and high-rise buildings, or in the retrofit and reinforcement of existing buildings. They dissipate seismic energy through elastic-plastic deformation of the steel itself. Especially in areas with high seismic intensity or significant wind loads, BRs can effectively alter the building's natural vibration frequency and deformation, while also absorbing energy, resulting in excellent energy dissipation and preventing structural damage.

[0003] Existing buckling-resistance energy-absorbing supports often use steel plates or components as energy-absorbing core materials, which absorb energy through buckling. Their energy-absorbing capacity is poor, and it is difficult to achieve high efficiency. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is that the energy dissipation capacity of the anti-buckling energy-dissipating support in the prior art is poor and the energy dissipation efficiency is low, so as to provide an anti-buckling support with stable and reliable energy dissipation capacity and improved energy dissipation efficiency.

[0005] In order to solve the above problems, the present invention provides an anti-buckling support suitable for connecting a first component and a second component, the anti-buckling support comprising:

[0006] an outer cylinder, wherein the outer cylinder has a first end and a second end along an axial direction thereof, and the first end is connected to the first member;

[0007] a first connecting rod, disposed in the outer cylinder near the first end;

[0008] an elastic member, disposed in the outer cylinder, and having one end connected to an end of the first connecting rod away from the first end;

[0009] The second connecting rod is partially disposed in the outer tube and close to the second end. One end of the second connecting rod is connected to the elastic member, and the other end is adapted to extend out of the outer tube and be connected to the second component.

[0010] As an optimal technical solution for anti-buckling support, when the elastic member is in a natural state, the second connecting rod and the elastic member satisfy the following relationship: Δ<L, wherein L represents the length of the second connecting rod extending out of the outer tube at one end away from the elastic member, and Δ represents the maximum compression amount when the elastic member is in a compressed state.

[0011] As an optimal technical solution for the anti-buckling support, a piston is also included, which is suitable for sliding connection in the outer tube, one end of the elastic member is connected to one side of the piston, and one end of the second connecting rod is connected to the other side of the piston.

[0012] As a preferred technical solution for the anti-buckling support, the elastic member is a spring, and the spring is a disc spring, a coil spring or a wave spring.

[0013] As a preferred technical solution for the anti-buckling support, a core filling material is provided between the first connecting rod and the outer cylinder.

[0014] As a preferred technical solution for the anti-buckling support, the core filling material is mortar or cement.

[0015] As an optimal technical solution for anti-buckling support, a first end plate and a second end plate are respectively provided at both ends of the outer tube, the first end plate is arranged at an end close to the first connecting rod, and the second end plate is arranged at an end of the outer tube close to the second connecting rod, the second end plate is provided with a through hole, the second connecting rod passes through the through hole, and the end of the second connecting rod away from the elastic member extends out of the second end plate.

[0016] As a preferred technical solution for the anti-buckling support, the first connecting rod is a solid or hollow round tube or square tube.

[0017] As a preferred technical solution for the anti-buckling support, the outer cylinder and the first connecting rod satisfy the following relationship: D≤3d, where D represents the diameter of the outer cylinder and d represents the diameter of the first connecting rod.

[0018] As an optimal technical solution for the anti-buckling support, it also includes a first ear plate and a second ear plate, the first ear plate is arranged at one end of the outer cylinder, and the outer cylinder is connected to the first component through the first ear plate, and the second ear plate is arranged at one end of the second connecting rod away from the elastic member, and the second connecting rod is connected to the second component through the second ear plate.

[0019] The technical solution of the present invention has the following advantages:

[0020] 1. The buckling-prevention support provided by the present invention, by disposing a first connecting rod, an elastic member, and a second connecting rod connected to the elastic member within an outer tube, can effectively prevent component buckling while changing the length of the buckling-prevention support through compression and extension of the elastic member. The elastic member consumes and stores energy, resulting in stable and reliable energy consumption capacity and improved energy consumption efficiency.

[0021] 2. In the buckling-prevention support provided by the present invention, when the elastic member is in its natural state, the second connecting rod and the elastic member satisfy the following relationship: Δ < L, where L represents the length of the second connecting rod's end extending from the outer tube away from the elastic member, and Δ represents the maximum compression of the elastic member when in a compressed state. When the spring is compressed by an external force away from the second connecting rod, because the spring's maximum compression is less than the length of the second connecting rod's end extending from the outer tube, even if the spring is compressed to its maximum compression away from the second connecting rod, the end of the second connecting rod away from the elastic member remains extended from the outer tube. This prevents external forces from acting directly on the outer tube, allowing the external forces to act on the elastic member through the second connecting rod. This allows the elastic member to consume and store energy, improving energy efficiency.

[0022] 3. In the anti-buckling support provided by the present invention, a piston is slidably connected to the outer cylinder. One end of the elastic member is connected to one side of the piston, and one end of the second connecting rod is connected to the other side of the piston. By directly placing the piston between the elastic member and the second connecting rod, and securing the second connecting rod to the piston, the second connecting rod is stabilized, increasing its compressive bending resistance and enhancing the overall robustness of the anti-buckling support.

[0023] 4. In the buckling-restrained support provided by the present invention, a core-filling material, such as mortar or cement, is provided between the first connecting rod and the outer tube. This core-filling material effectively constrains the first connecting rod, improving its strength and preventing lateral buckling failure under high pressure, thereby increasing the bearing capacity of the buckling-restrained support.

[0024] 5. The buckling prevention support provided by the present invention comprises a first end plate and a second end plate at each end of the outer tube, the first end plate being located at the end closest to the first connecting rod, and the second end plate being located at the end of the outer tube closest to the second connecting rod. The second end plate defines a through hole, through which the second connecting rod extends, and the end of the second connecting rod distal to the elastic member extends out of the second end plate. The first end plate seals and shields the outer tube, inner tube, and core material, improving the aesthetics. The second end plate allows the second connecting rod to freely extend and retract through the through hole, providing a certain degree of restraint for the second connecting rod, allowing it to move axially along the through hole and preventing radial forces.

[0025] 6. In the buckling-restrained support provided by the present invention, the outer cylinder and the first connecting rod satisfy the following relationship: D ≤ 3d, where D represents the diameter of the outer cylinder and d represents the diameter of the first connecting rod. This ensures the overall stability of the buckling-restrained support. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0038] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0039] like Figures 1 to 6 FIG. 1 is a preferred embodiment of the anti-buckling brace of the present invention. The anti-buckling brace has stable and reliable energy dissipation capability and improves energy dissipation efficiency.

[0040] The anti-buckling support of this embodiment is suitable for connecting a first component and a second component, and the anti-buckling support includes: an outer cylinder 1, a first connecting rod 2, an elastic member 3 and a second connecting rod 4. The outer cylinder 1 has a first end and a second end along its axial direction, and the first end is connected to the first component; the first connecting rod 2 is arranged in the outer cylinder 1 close to the first end; the elastic member 3 is arranged in the outer cylinder 1, and one end of the elastic member 3 is connected to the end of the first connecting rod 2 away from the first end; the second connecting rod 4 is partially arranged in the outer cylinder 1 and close to the second end, one end of the second connecting rod 4 is connected to the elastic member 3, and the other end is suitable for extending out of the outer cylinder 1 to be connected to the second component.

[0041] A first connecting plate 7 is fixedly provided between the first connecting rod 2 and the elastic member 3 . The cross-sectional shape of the first connecting plate 7 is the same as that of the outer cylinder 1 , and the central axis of the first connecting plate 7 coincides with the central axis of the outer cylinder 1 .

[0042] The above-mentioned anti-buckling support, by arranging a first connecting rod 2, an elastic member 3 and a second connecting rod 4 connected to the elastic member 3 in the outer tube 1, can effectively avoid the buckling of the component while changing the length of the anti-buckling support through the compression and extension of the elastic member 3. The elastic member 3 consumes and stores energy, the energy consumption capacity is stable and reliable, and the energy consumption efficiency is improved.

[0043] In an optional implementation of this embodiment, when the elastic member 3 is in a natural state, the second connecting rod 4 and the elastic member 3 satisfy the following relationship: Δ<L, where L represents the length of the second connecting rod 4 extending out of the outer tube 1 at the end away from the elastic member 3, and Δ represents the maximum compression amount of the elastic member 3 when it is in a compressed state. Specifically, Figure 1 As shown, the length L of the second connecting rod 4 extending out of the outer tube 1, when the spring is compressed toward the side away from the second connecting rod 4 by an external force, since the maximum compression of the spring is less than the length of the second connecting rod 4 extending out of the outer tube 1, even if the spring is compressed to the side away from the second connecting rod 4 to the maximum compression, the end of the second connecting rod 4 away from the elastic member 3 is still in a position extending out of the outer tube 1, avoiding the external force from directly acting on the outer tube 1, so that the external force acts on the elastic member 3 through the second connecting rod 4, and the elastic member 3 consumes and stores energy, thereby improving energy consumption efficiency.

[0044] In an optional embodiment of this embodiment, a piston 5 is further included, which is suitable for sliding connection in the outer tube 1, one end of the elastic member 3 is connected to one side of the piston 5, and one end of the second connecting rod 4 is connected to the other side of the piston 5. Specifically, Figure 1 As shown, the cross-sectional shape of the piston 5 is the same as that of the outer tube 1. In this embodiment, the cross-sectional shape of the piston 5 is circular, and the central axis of the piston 5 coincides with the central axis of the outer tube 1. The two ends of the piston 5 are respectively fixedly connected to the elastic member 3 and the second connecting rod 4, which are welded in this embodiment. By directly arranging the piston 5 on the elastic member 3 and the second connecting rod 4, the second connecting rod 4 is fixed to the piston 5, which can stabilize the second connecting rod 4, increase the compressive anti-bending stability of the second connecting rod 4, and improve the overall stability of the anti-buckling support.

[0045] In an optional embodiment of this embodiment, the elastic member 3 is a spring, which can be a disc spring, a coil spring, or a wave spring. In this embodiment, a coil spring is used. When a coil spring is used as an energy-dissipating element, the deformation of the spring satisfies Hooke's law. The model and size of the spring are determined based on the load-bearing capacity and deformation required for the specific project. When an external force pushes the second connecting rod 4 toward the first connecting rod 2, the second connecting rod 4 drives the piston 5 to move synchronously, thereby compressing the spring and achieving an energy-dissipating effect. When an external force pulls the second connecting rod 4 away from the first connecting rod 2, it drives the piston 5 to move synchronously, thereby extending the spring and achieving an energy-dissipating effect. At the same time, the friction between the internal components of the anti-buckling support during deformation can also provide a certain energy-dissipating capacity.

[0046] In an optional implementation of this embodiment, a core filling material 6 is provided between the first connecting rod 2 and the outer cylinder 1; the core filling material 6 is mortar or cement. Figure 1 and Figure 3 As shown, in this embodiment, mortar is filled between the first connecting rod 2 and the outer tube 1. The mortar has the advantages of fast setting, high strength, strong adhesion and no shrinkage. By filling the mortar between the first connecting rod 2 and the outer tube 1, an effective constraint is provided to the first connecting rod 2, the strength of the first connecting rod 2 is improved, and the lateral deformation, buckling and failure of the first connecting rod 2 under greater pressure are avoided, thereby improving the bearing capacity of the anti-buckling support.

[0047] In an optional implementation of this embodiment, the first connecting rod 2 is a solid or hollow round tube or square tube. Figure 1 and Figure 2 As shown, in this embodiment, the outer cylinder 1 is a hollow circular tube, which can play the role of anti-buckling support and compressive stability. The first connecting rod 2 is a hollow square tube. The first connecting rod 2 is a key component of the anti-buckling support that bears axial tension or pressure. The central axis of the outer cylinder 1 coincides with the central axis of the first connecting rod 2 to ensure the overall force stability of the rod.

[0048] In other embodiments, the first connecting rod 2 may also be a solid circular tube, a solid square tube or a hollow circular tube.

[0049] In an optional implementation of this embodiment, the outer cylinder 1 and the first connecting rod 2 satisfy the following relationship: D≤3d, where D represents the diameter of the outer cylinder 1 and d represents the diameter of the first connecting rod 2. Specifically, Figure 3 As shown, in this embodiment, the first connecting rod 2 is a square tube, and the diameter of its circumscribed circle can be calculated according to the side length of the first connecting rod 2, so that the diameter of the circumscribed circle satisfies D≤3d, thereby ensuring the overall stability of the anti-buckling support.

[0050] In an optional implementation of this embodiment, a first end plate 8 and a second end plate 9 are respectively provided at both ends of the outer cylinder 1. The first end plate 8 is provided at an end close to the first connecting rod 2, and the second end plate 9 is provided at an end close to the second connecting rod 4 of the outer cylinder 1. The second end plate 9 is provided with a through hole, and the second connecting rod 4 passes through the through hole, and the end of the second connecting rod 4 away from the elastic member 3 extends out of the second end plate 9. Specifically, Figure 1 and Figure 6As shown, in this embodiment, the cross-sectional shape of the first end plate 8 and the second end plate 9 is the same as the cross-sectional shape of the outer cylinder 1, and the central axes of the first end plate 8 and the second end plate 9 coincide with the central axis of the outer cylinder 1. The first end plate 8 is welded to the end of the first end of the outer cylinder 1, and the second end plate 9 is welded to the end of the second end of the outer cylinder 1. By setting the first end plate 8, the outer cylinder 1, the inner cylinder and the core filling material 6 can be sealed and shielded to improve the aesthetics; by setting the second end plate 9, the second connecting rod 4 can be freely extended and retracted through the through hole, which can play a certain limiting role on the second connecting rod 4, so that the second connecting rod 4 moves axially along the through hole to avoid radial force.

[0051] In an optional implementation of this embodiment, a first ear plate 10 and a second ear plate 11 are further included. The first ear plate 10 is provided at one end of the outer tube 1, and the outer tube 1 is connected to the first component via the first ear plate 10. The second ear plate 11 is provided at one end of the second connecting rod 4 away from the elastic member 3, and the second connecting rod 4 is connected to the second component via the second ear plate 11. Specifically, Figure 1 、 2 As shown in 6, the first ear plate 10 is welded to the end of the first end plate 8 away from the first connecting rod 2, and the second ear plate 11 is welded to the end of the second connecting rod 4. The first ear plate 10 and the second ear plate 11 are both provided with connecting holes, which can be connected to the first component and the second component respectively through the connecting holes with bolts or pins, which is convenient for installation.

[0052] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
