Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to an anti-seismic support rod. Background Technology

[0002] Seismic bracing rods are key components of a building's seismic resistance system. They are mainly made of metal profiles and are often connected to the main building structure, pipelines, and equipment. Their core function is to transmit and dissipate seismic energy during an earthquake by utilizing their own stiffness and deformation resistance, limiting the displacement of building components and electromechanical pipelines, preventing structural damage due to excessive shaking or collisions, and reducing the risk of non-structural components falling. This ensures the overall stability of the building and the safety of people and property, and they are widely used in high-rise buildings, public venues, industrial plants, and other scenarios.

[0003] Currently, commonly used seismic bracing rods consist of a support rod body and two connecting seats. The two connecting seats are respectively located at both ends of the support rod body. The support rod body and the connecting seats are rigidly connected, and the support rod body mainly relies on its rigidity to resist external forces. This results in poor absorption and dissipation of the impact energy generated by earthquakes, thus reducing the effectiveness of the seismic bracing rods. Utility Model Content

[0005] The technical solution adopted by this utility model to solve its technical problem is: a seismic support rod, including a support rod body and two connecting seats. The support rod body includes a rod body part and two connecting parts. The two connecting parts are respectively arranged at both ends of the rod body part. A connecting groove is provided on the outer end of the connecting part. The central axis of the connecting groove is the same as or parallel to the central axis of the rod body part. It also includes two sliding bases and two sets of elastic buffer components, with the sliding bases, elastic buffer components, connecting parts, and connecting seats connected one-to-one; One end of the elastic buffer component is connected to the bottom of the connecting groove, and the other end of the elastic buffer component is connected to the inner end of the sliding base. The inner end of the sliding base is set in the connecting groove, and the sliding base can slide back and forth along the central axis of the connecting groove. The outer ends of the connecting seat and the sliding base are hinged together by a ball joint.

[0006] Furthermore, a fixing groove is provided on the inner end of the connecting part, and the rod body is matched and fixed in the fixing groove.

[0007] Furthermore, the elastic cushioning component includes a disc spring and an elastic rubber post, with the elastic rubber post fitted inside the disc spring.

[0008] Furthermore, the sliding base includes a first cylindrical portion, a second cylindrical portion, and a frustum portion connected in sequence. The cross-sectional diameter of the first cylindrical portion is smaller than that of the second cylindrical portion. The outer end of the first cylindrical portion is located at the middle of the inner end of the second cylindrical portion. The outer end of the second cylindrical portion is connected to the inner end of the frustum portion. The cross-sectional diameter of the frustum portion gradually decreases along the direction from the inner end to the outer end of the frustum portion.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] like Figures 1 to 6 As shown, the present invention provides an anti-seismic support rod, comprising a support rod body 1 and two connecting seats 2, the two connecting seats 2 being respectively disposed at both ends of the support rod body 1. The support rod body 1 includes a rod body portion 11 and two connecting portions 12, the two connecting portions 12 being respectively disposed at both ends of the rod body portion 11. A connecting groove 13 is provided on the outer end of the connecting portion 12, and the central axis of the connecting groove 13 is the same as or parallel to the central axis of the rod body portion 11. It also includes two sliding bases 3 and two sets of elastic buffer components. The sliding bases 3, elastic buffer components, connecting parts 12 and connecting seats 2 are connected to the two ends of the rod body 11 in a one-to-one correspondence. One end of the elastic buffer component is connected to the bottom of the connecting groove 13, and the other end of the elastic buffer component is connected to the inner end of the sliding base 3. The inner end of the sliding base 3 is set in the connecting groove 13, and the sliding base 3 can slide back and forth along the central axis of the connecting groove 13. The outer ends of the connecting seat 2 and the sliding base 3 are hinged together by the ball head 4.

[0019] In this utility model, the inner end refers to the end of a component that is relatively closer to the rod 11; the outer end refers to the end of a component that is relatively farther away from the rod 11.

[0020] By incorporating an elastic buffer assembly between the support rod 1 and the connecting seat 2, the compression deformation of the elastic buffer assembly absorbs the impact energy generated by the earthquake, dissipating some of the energy, extending the impact response time, reducing structural damage, and improving the performance of the seismic support rod. Furthermore, the outer ends of the connecting seat 2 and the sliding base 3 are hinged together via ball joints, allowing the support rod 1 to adapt to multi-directional displacement, preventing forced deformation, and reducing stress concentration at the connection point, further enhancing the performance of the seismic support rod.

[0021] Specifically, to facilitate the connection between the rod body 11 and the connecting part 12, and to allow for replacement in case of damage, for example... Figure 2 As shown, a fixing groove 14 is provided on the inner end of the connecting part 12, and the rod part 11 is matched and fixed in the fixing groove 14.

[0022] Elastic buffer components absorb the impact energy generated by earthquakes through compression deformation. To improve the effectiveness of elastic buffer components, for example... Figure 3 As shown, the elastic buffer assembly includes a butterfly spring 51 and an elastic rubber column 52, with the elastic rubber column 52 fitted inside the butterfly spring 51. The elastic rubber column 52 is cylindrical in shape. One end of both the butterfly spring 51 and the elastic rubber column 52 is connected to the bottom of the connecting groove 13, and the other end of both the butterfly spring 51 and the elastic rubber column 52 is connected to the inner end of the sliding base 3. The butterfly spring 51 and the elastic rubber column 52 are compressed or stretched synchronously.

[0023] To improve the performance of the sliding base 3 and enable the support rod 1 to adapt to multi-directional displacement, for example... Figure 1 , Figure 5 As shown, the sliding base 3 includes a first cylindrical portion 31, a second cylindrical portion 32, and a frustum portion 33 connected sequentially. The diameter of the cross-sectional circle of the first cylindrical portion 31 is smaller than that of the second cylindrical portion 32. The outer end of the first cylindrical portion 31 is located at the middle of the inner end of the second cylindrical portion 32. The outer end of the second cylindrical portion 32 is connected to the inner end of the frustum portion 33, and the diameter of the cross-sectional circle of the frustum portion 33 gradually decreases along the direction from the inner end to the outer end. A damping ring 6 is fitted onto the first cylindrical portion 31 and is matched and disposed in the connecting groove 13. The second cylindrical portion 32 acts as a limiter, allowing the damping ring 6 to be installed and used normally. The damping ring 6 consumes energy through intermolecular friction and prevents rigid collisions, prolonging the impact response time and reducing structural damage. The frustum portion 33 allows the support rod 1 to adapt to multi-directional displacement.

[0024] To reduce the possibility of the disc spring 51 shifting during compression or tension, a limiting groove 34 is provided on the inner end of the first cylindrical portion 31, and the disc spring 51 is matched and disposed in the limiting groove 34. The limiting groove 34 limits the disc spring 51, thereby reducing the possibility of the disc spring 51 shifting during use.

[0025] To further improve the performance of support rod 1, in such cases... Figure 1 As shown, an annular reinforcing ring 7 is provided in the middle of the rod body 11, and the annular reinforcing ring 7 is arranged along the length direction of the rod body 11. The annular reinforcing ring 7 can increase the moment of inertia of the supporting rod body 1, improve its critical buckling load, and reduce the possibility of the rod body buckling due to instability during an earthquake.

[0026] To reduce the possibility of breakage in the rod section 11, for example... Figure 1 , Figure 6As shown, this utility model also includes at least one steel cable 81, with both ends of the steel cable 81 detachably connected to two connecting parts 12 via wedge-shaped anchors 82. The steel cable 81 is disposed on the side of the pole body 11. When an earthquake generates tension, the steel cable 81 is first tightened and quickly transmits the load, reducing the tension on the pole body 11 and preventing excessive instantaneous tensile stress that could cause the pole body 11 to break. To ensure the effectiveness of the steel cable 81, it is preferable to have two steel cables 81, which are respectively disposed on both sides of the pole body 11 and are arranged parallel to each other.

[0027] To facilitate the installation and use of connector 2, for example... Figure 4 As shown, the connecting seat 2 includes an outer connecting seat body 21 and an inner connecting seat body 22. The inner connecting seat body 22 is located in the middle of the outer connecting seat body 21. The inner connecting seat body 22 is hinged to the sliding base 3 through a ball joint 4. Connecting holes 23 are provided around the outer connecting seat body 21. The outer connecting seat body 21 is preferably a cube, and its shape is preferably cylindrical.
