Description

Technical Field

[0001] The utility model relates to the technical field of earthquake-resistant supports, in particular to an earthquake-resistant support for a large-span and high-load-bearing steel structure. Background Art

[0002] Seismic bearings are key components used in structures such as buildings and bridges to improve their seismic resistance. Their primary function is to reduce structural vibration and deformation under dynamic loads such as earthquakes, thereby protecting the safety and stability of buildings.

[0003] Upon investigation, a Chinese patent discloses a large-span, high-load-bearing steel structure seismic bearing (publication number: CN215977731U), which includes a bearing body, a spherical core installed on the top of the bearing body, a spherical steel block arranged on the top of the spherical core, and a clamping part arranged on the outer wall of the spherical steel block; a plurality of V-grooves are arranged on the top of the spherical core; wherein after the bottom of the spherical steel block is fitted with the spherical core, the protrusion can be placed just in the groove.

[0004] In the above patent, a spherical core is set on the top of the support body, and a spherical steel block is installed on the top of the spherical core. The bottom of the spherical steel block can fit with the surface of the spherical core, so that the support body can effectively disperse the vertical pressure generated by the large-span steel structure. When the spherical steel block presses down the spherical core, the clamping part can limit the horizontal direction of the spherical steel block to prevent the spherical steel block from shaking left and right. At the same time, the provided protrusion cooperates with the V-groove, and the protrusion can be stuck in the V-groove, so that the stability of the support body can be further improved. However, during an earthquake, it mostly relies on the occurrence of displacement, and may not be able to effectively control vibration in some cases. In addition, its ability to absorb earthquake vibrations is weak, and it may be subjected to a greater impact in a strong earthquake, and its seismic effect is limited.

[0005] Therefore, the present invention provides a large-span, high-load-bearing steel structure seismic support to solve the above problems. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the present invention are: through the setting of external components, multiple rubber pads are overlapped and arranged on the lower surface of the lower support, which can reduce the transmission of seismic waves to the structure, thereby reducing the impact of earthquakes on buildings and improving the overall seismic resistance. At the same time, the bottom shell and the top shell provide limitation and protection for the periphery of the rubber pad, which can limit the lateral deformation range of the rubber pad, ensuring that it maintains a good shape and performance when subjected to force, thereby further improving the shock absorption effect, and the wear-resistant plate prevents the rubber pad from being worn when the bottom shell and the top shell are displaced, affecting the stability and safety of the overall structure.

At the same time, the bottom shell 1 and the top shell 2 provide limitation and protection for the periphery of the rubber pad 4, which can limit the lateral deformation range of the rubber pad 4, ensuring that it maintains a good shape and performance when subjected to force, thereby further improving the shock absorption effect, and the anti-wear plate 3 prevents the rubber pad 4 from being worn when the bottom shell 1 and the top shell 2 are displaced, affecting the stability and safety of the overall structure.

[0028] Example 2:

[0029] Based on Example 1:

[0030] The external component includes an inner shell 5, the lower surface of the inner shell 5 is fixedly connected to the periphery of the bottom shell 1 on the upper surface of the lower connecting component, the outer surface of the inner shell 5 is slidably connected to the outer shell 6, and the inner side wall of the outer shell 6 is fixedly connected to the limiting ring 7. Space is left between the inner shell 5 and the outer shell 6 to avoid displacement, which causes it to lose its seismic effect. The limiting ring 7 is located in the interlayer between the lower support 11 and the upper support 15, which limits the outer shell 6 to prevent it from excessive displacement from the inner shell 5.

[0031] The connecting assembly includes a fixing plate 8, the lower surface of which is fixedly connected to the upper surface of the shell 6, the upper surface of the fixing plate 8 is fixedly connected to a connecting bolt 9, the outer surface of the connecting bolt 9 is threadedly connected to a nut 10, the connecting bolt 9 is used to connect the fixing plate 8 to the upper and lower structures respectively, and the nut 10 is used to fix it, so as to fix the device in the desired position.

[0032] The support assembly includes a lower support 11, the middle part of the lower surface of the lower support 11 is fixedly connected to the upper surface of the top shell 2, a damping rod 12 is fixedly connected to the edge of the lower surface of the lower support 11, a spring 13 is sleeved on the outer surface of the damping rod 12, an arc groove is opened in the middle part of the upper surface of the lower support 11, an arc plate 14 is fixedly connected to the inside of the arc groove, the bottom end of the damping rod 12 is connected to the upper surface of the inner shell 5, and combined with the spring 13, it can effectively absorb seismic energy and reduce the impact on the upper structure.

The spherical crown plate 17 is displaced inside the arc plate 14, thereby adapting to the deformation of the upper structure, reducing stress concentration, and reducing the risk of structural damage.

[0034] The lower surface of the spherical crown plate 17 is adapted to the shape of the upper surface of the arc plate 14. The lower surface of the spherical crown plate 17 overlaps the upper surface of the arc plate 14. The spherical crown plate 17 is adapted to the arc plate 14 to prevent it from completely detaching while causing displacement.

[0035] Example 3:

[0036] Based on Example 1 and Example 2:

[0037] First, use the connecting bolts 9 to connect the fixing plates 8 to the upper and lower structures respectively, and use the nuts 10 to fix them. Then, multiple rubber pads 4 are overlapped and arranged on the lower surface of the lower support 11. When an earthquake occurs, at the same time, the bottom shell 1 and the top shell 2 provide limitation and protection for the periphery of the rubber pad 4, which can limit the lateral deformation range of the rubber pad 4. The wear-resistant plate 3 prevents the bottom shell 1 and the top shell 2 from causing wear to the rubber pad 4, and reduces the transmission of seismic waves to the structure through the rubber pad 4. Secondly, the bottom end of the damping rod 12 is connected to the upper surface of the inner shell 5, and combined with the spring 13, it can effectively absorb seismic energy. Finally, the limiting ring 7 is in the interlayer between the lower support 11 and the upper support 15 to limit the outer shell 6, and the spherical crown plate 17 is displaced inside the arc plate 14, thereby adapting to the deformation of the upper structure and performing shock absorption.
