Description

Technical Field

[0001] This invention relates to a seismic isolation bearing, specifically a double-layer sliding-tensile ring self-resetting metal seismic isolation bearing. Background Technology

[0002] Seismic isolation bearings are an important type of seismic isolation component. While bearing the load of the superstructure, they often also have the function of self-resetting after an earthquake.

[0003] Traditional seismic isolation bearings typically use rubber as the isolation material. While rubber is stable and has good self-resetting properties, it suffers from aging over time, leading to performance degradation. This makes it difficult to perform effectively during earthquakes, and rubber is inconvenient to process and install, and difficult to replace after an earthquake. Friction pendulum bearings use curved sliders to dissipate energy through friction, mitigating seismic forces, but their effectiveness in reducing the displacement response of the superstructure is not ideal. Most of the aforementioned seismic isolation bearings lack tensile and overturning resistance capabilities. Furthermore, earthquake vibrations are random in direction, while most current seismic isolation bearings can only achieve unidirectional isolation, which is detrimental to the seismic isolation of building structures. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a double-layer sliding-tensile ring self-resetting metal seismic isolation bearing. This bearing has tensile and overturning resistance functions and can achieve multi-directional seismic isolation.

[0005] To achieve the above objectives, the present invention discloses a double-layer sliding-tensile ring self-resetting metal seismic isolation bearing, comprising an inner sleeve and two outer sleeve top plates;

[0006] The inner sleeve is located between the top plates of the two outer sleeves, and an inner sleeve top plate is provided between the inner sleeve and the top plates of the outer sleeves. The inner sleeve top plate is fixed at the opening at the end of the inner sleeve, and the inner sleeve top plate is in contact with the top plate of the outer sleeve.

[0007] An outer sleeve is provided at the end of the top plate of the outer sleeve. The outer sleeve is sleeved on the inner sleeve. An outer ring plate is fixed on the inner wall of the outer sleeve. An inner ring plate is sleeved and fixed on the inner sleeve, and the surface of the outer ring plate is in contact with the surface of the inner ring plate.

[0008] It also includes several springs, wherein one end of each spring is fixed to the outer wall of the inner sleeve, and the other end of each spring is fixed to the inner wall of the outer sleeve.

[0009] The inner sleeve is filled with concrete.

[0010] A stiffening plate is provided between the outer ring plate and the inner wall of the outer sleeve.

[0011] A stiffening plate is provided between the inner annular plate and the outer wall of the inner sleeve.

[0012] The number of outer sleeves is two, and the two outer sleeves are respectively loosely fitted on the upper and lower sides of the inner sleeve.

[0013] It also includes threaded steel pipes, wherein each threaded steel pipe is disposed on the top plate of the outer sleeve.

[0014] The top plate of the outer sleeve is provided with several through holes, each through hole corresponding to a threaded steel pipe, and each through hole is connected to its corresponding threaded steel pipe.

[0015] One end of the spring is connected to the inner wall of the outer sleeve via a first connector, and the other end of the spring is connected to the outer wall of the inner sleeve via a second connector.

[0016] The first and second connecting members include a spring connecting plate, a sleeve lug plate, and a connecting lug plate. The end of the spring is connected to one side of the spring connecting plate, the connecting lug plate is fixed to the other side of the spring connecting plate, and the sleeve lug plate is axially connected to the connecting lug plate. The sleeve lug plate in the first connecting member is fixed to the inner wall of the outer sleeve, and the sleeve lug plate in the second connecting member is fixed to the outer wall of the inner sleeve.

[0017] The second connector further includes a buckling-resistant steel rod, wherein one end of the buckling-resistant steel rod is fixed to the side of the spring connecting plate, and the other end of the buckling-resistant steel rod is inserted into the spring axially.

[0018] Molybdenum disulfide self-lubricating coating is sprayed between the top plate of the inner sleeve and the top plate of the outer sleeve.

[0019] The present invention has the following beneficial effects:

[0020] In specific operation, the double-layer sliding-tensile ring self-resetting metal seismic isolation bearing of the present invention has the inner sleeve top plate in contact with the outer sleeve top plate, and the surface of the outer ring plate in contact with the surface of the inner ring plate. When seismic energy is input, the relative displacement occurs between the outer sleeve top plate and the inner sleeve, and the displacement direction is consistent with the seismic vibration direction, thereby achieving multi-directional seismic isolation and damping. At the same time, energy is dissipated through friction between the outer ring plate and the inner ring plate, and the outer sleeve provides limiting. Furthermore, the phase interaction between the outer ring plate and the inner ring plate provides tensile and anti-overturning resistance. Attached Figure Description
