Description

Technical Field

[0001] The present application belongs to the technical field of building seismic isolation, and specifically relates to an anti-overturning device for a building seismic isolation support. Background Art

[0002] In earthquake zones, seismic isolation bearings used for houses, bridges or other structures can effectively isolate the transmission of seismic energy to the upper structure when an earthquake occurs, thereby reducing the damage caused by earthquake disasters to buildings or bridges. However, the structural characteristics of seismic isolation bearings determine that their tensile strength is very low, especially the vertical tensile capacity is poor, and its ultimate tensile strength is only 6% to 8% of the ultimate compressive strength. When a strong earthquake occurs, huge tensile stress is generated under the simultaneous action of horizontal and vertical vibrations, which will cause the seismic isolation bearings to be damaged. In addition, the vertical seismic force is often very large in strong earthquakes, and the height-to-width ratio of high-rise buildings is large, and the overturning moment is also large, which makes the seismic isolation layer often lift off. The current seismic isolation bearings basically do not have the anti-overturning lift-off function. A few have anti-overturning functions but the functions are limited, resulting in overturning damage to the building. Moreover, once the seismic isolation bearings are damaged during a strong earthquake, they will pose a hidden danger to the safety of the building. Therefore, the insufficiency of seismic isolation bearings has become one of the main obstacles to the promotion and application of seismic isolation technology in high-rise buildings. In addition, it is difficult to avoid the damage of seismic isolation bearings by strong earthquakes.

[0003] For example, the application with publication number CN209836785U discloses an anti-overturning device for cooperating with a building seismic isolation support; the anti-overturning device comprises a first longitudinal guide rail (100), a vertical damping device (300) and two first transverse guide rails (200) respectively fixedly mounted on the building body and parallel to each other; the bottom of the vertical damping device (300) is directly or indirectly mounted on the ground surface, and the top of the vertical damping device (300) can be relatively slidably mounted on the first longitudinal guide rail (100); the first longitudinal guide rail (100) can be relatively slidably mounted on the two first transverse guide rails (200). The anti-overturning device of the utility model is ingeniously designed and highly practical.

[0004] However, in this application, the overall device is extended and connected externally, which occupies a lot of external space, and the internal components need to be supported, which wastes the corresponding reinforced concrete space. Utility Model Content

[0007] By adopting the above technical scheme, the positioning steel plate is fixed by tightening the nuts, the U-shaped connecting piece is fixed on all sides, and the internal buffer piece and the buffer body shell constitute the buffer body. The deformation buffering of the arc-shaped buffer piece is used to ensure the stability of the external buffering of the seismic isolation bearing.

The inner and outer connecting rods can move up and down at the fixing ring. The outer connecting rods are welded at the overall connection to form a whole. Therefore, after stress is generated in the seismic isolation bearing, the inner or outer connecting rod is transferred to the U-shaped connecting piece through force, and the cross connection at the other end transfers the force to the reverse position, ensuring that the stress is balanced at the reverse position and more evenly supported as a whole.

[0011] By adopting the above technical solution, the carbon fiber has the characteristic of high toughness, which ensures good buffering of the buffer body shell corresponding to the buffer sheet.

[0012] In a preferred embodiment, a fixing sleeve is fixedly connected to the outer surface of the U-shaped connecting piece corresponding to the positioning hole, and a fixing sleeve is also fixedly connected to the outer surface of the buffer piece at a corresponding position.

[0013] By adopting the above technical solution, the fixing sleeve ensures that the U-shaped connecting piece and the buffer piece are fixed well accordingly, further ensuring the stable operation of the equipment.

[0014] In a preferred embodiment, the U-shaped connecting piece is fixedly connected to a welding piece corresponding to the outer surface of the outer connecting rod, and the buffer piece is fixedly connected to a welding piece corresponding to the outer surface of the inner connecting rod.

[0015] By adopting the above technical solution, the welding sheet facilitates welding of the inner connecting rod and the outer connecting rod to ensure that they are integrated.

[0016] In a preferred embodiment, a fixing block is movably connected to the outer surface of the positioning steel plate corresponding to the positioning hole, and an extension rod is welded to the outer surface of the nut.

[0017] By adopting the above technical solution, the equipment extension rod and the fixing block constitute a traditional anchoring assembly.

[0018] In a preferred embodiment, a nut is movably connected to the inner surface of the fixing block, and a seismic isolation support is provided on the outer surface of the positioning steel plate.

[0019] By adopting the above technical solution, the positioning steel plate is fixed by tightening the nut, and the seismic isolation bearing completes the main function of vibration reduction and vibration resistance.

[0020] In a preferred embodiment, the U-shaped connecting piece is made of 316L stainless steel and has a chrome-plated surface.

[0021] By adopting the above technical solutions, 316L stainless steel has the characteristics of high hardness, good shock resistance and good durability, and the chrome-plated surface further ensures the stability of the parts.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0023] In the present application, the positioning steel plate is fixed by tightening the nuts, the U-shaped connecting piece is fixed on all sides, and the internal buffer piece and the buffer body shell constitute the buffer body. The deformation buffering of the arc-shaped buffer piece is used to ensure the stability of the external buffering of the seismic isolation bearing. The other end of the inner connecting rod is connected to the buffer piece, and the other end of the outer connecting rod is connected to the U-shaped connecting piece. The inner and outer connecting rods can move up and down at the fixed ring. The outer connecting rods are welded at the overall connection to form a whole. Therefore, after stress is generated in the seismic isolation bearing, the inner or outer connecting rod is subjected to force and is transmitted to the U-shaped connecting piece, and the cross connection at the other end transmits the force to the reverse position, ensuring that the stress is balanced at the reverse position and is more evenly distributed to the support as a whole.
