Problems solved by technology

[0004] For example, Chinese patent CN201810015819.3 discloses a hyperboloid shock-absorbing and isolating spherical bearing with large damping. The damping can improve the shock absorption and isolation function of the hyperboloid bearing, but there is a risk of leakage of the damper, and the structure may fail under the action of an earthquake. At the same time, the structure requires a large installation space and high cost

Embodiment Construction

[0033] The present invention will be further described below with reference to the accompanying drawings.

[0034] figure 1 and figure 2 A shock isolation mount 100 according to the present invention is shown. like figure 1 and 2 As shown, the shock isolation mount 100 includes an upper sliding plate assembly 1 , a lower sliding plate assembly 6 , a motion assembly and a damping assembly 9 . Wherein, the upper sliding plate assembly 1 and the lower sliding plate assembly 6 are disposed up and down opposite to each other, and can move relatively laterally and longitudinally. The moving assembly is arranged between the upper sliding plate assembly 1 and the lower sliding plate assembly 6 . And the moving component has a convex curved lining plate 3 and a concave curved middle seat plate 5 which is matched and arranged under the convex curved lining plate 3 . The upper end of the convexly curved lining plate 3 is in contact with the upper sliding plate assembly 1 , and the...

Abstract

The present invention proposes a shock-absorbing and isolating bearing, which includes an upper sliding plate assembly; a lower sliding plate assembly; The concave curved middle seat plate is arranged under the convex curved liner; the damping assembly is configured to be compressively deformed to absorb or consume energy when the upper sliding plate assembly and the lower sliding plate assembly move relatively longitudinally or / and laterally, The shock-absorbing and isolating support can not only realize the functions of vertical load bearing, guiding slip and rotation, but also ensure the effective absorption and dissipation of seismic energy through the damping component under seismic conditions, so as to realize its shock-absorbing and isolating function. At the same time, The damping component realizes energy dissipation and absorption through deformation, has no risk of leakage, has a high safety factor, and has a simple structure.

Description

technical field [0001] The invention belongs to the technical field of vibration reduction and isolation of bridge structures, and in particular relates to a vibration reduction and isolation bearing. Background technique [0002] As an important social infrastructure, bridges have the characteristics of large investment, strong publicity, and difficult management and maintenance. Therefore, the seismic disaster prevention management of bridges is very important, and improving the seismic performance of bridges is the basic measure to reduce earthquake losses. [0003] With the development of bridge structure design technology, more and more bridges adopt the seismic isolation design scheme. At present, common shock isolation products include cable bearings, friction pendulum bearings, lead rubber bearings, high damping rubber bearings, and steel damping vibration isolation bearings. [0004] For example, Chinese patent CN201810015819.3 discloses a large-damping hyperboloi...
