specific Embodiment approach

[0031] The present invention aims to provide a ring-shaped friction rotating shock-isolation bearing, which provides ring-shaped friction through rotation deformation, and sets a frequency conversion shock-isolation system and a buffer spring to improve the deformation capacity of the shock-isolation mount and realize the next direction of extremely large earthquakes and long-period earthquakes. Seismic performance goals of the limit. The specific implementation is as follows:

[0032] Such as figure 1 As shown in the figure, a ring-shaped friction-rotation shock-isolation device that can be used for shock absorption of buildings and bridges is composed of an upper cover plate 1, a rotating rigid body 2 in bite contact with the upper cover plate 1, and an annular friction wall in contact with the lateral curved surface of the rotating rigid body 2 3. The buffer spring 4 connected to the lower part of the rotating rigid body 2, the lower part of the buffer spring 4 is connecte...

Abstract

The invention relates to an annular frictional rotating shockproof supporting base. The annular frictional rotating shockproof supporting base comprises an upper cover plate, a rotating rigid body, an annular frictional wall, a buffer spring, a suspending steel block, and a base; the lower part of the upper cover plate is provided with a convex hemispheroid, the upper part of the rotating rigid body is provided with a groove, and the convex hemispheroid is meshed and contacted with the groove; the center of the lower part of the rotating rigid body is provided with a spherical groove, and the spherical groove is in supporting connection with the hemispheroid to form rotating contact in every direction; the overall side face of the rotating rigid body is provided with a spherical face and forms a frictional contact with the annular frictional wall; when the rotating rigid body is rotated, the rotating rigid body rubs the annular frictional wall to dissipate the earthquake energy; one ring at the bottom part of the rotating rigid body is provided with a vertical buffer spring, and the other end of the buffer spring is connected with the suspending steel block; the suspending steel block is placed in a block opening of the base, and the thickness of the suspending steel block is less than the height of the block opening; when the rotating rigid body is rotated to a certain position, the buffer spring can upwards raise up so as to drive the suspending steel block to upwards move; when the buffer spring is contacted with the block opening, the buffer spring is stretched to limit the movement of the rotating rigid body.

Description

technical field [0001] The invention relates to a shock-isolation support, in particular to an annular friction-rotation shock-isolation support, which belongs to the technical field of shock-isolation supports. Background technique [0002] Local damage to engineering structures such as traditional buildings or bridges caused by earthquakes is the main cause of their collapse. Vibration control technology is one of the effective shock-absorbing strategies to avoid resonance by dissipating the input energy of the earthquake and prolonging the structural period. [0003] At present, the relatively mature seismic isolation bearing products developed at home and abroad mainly include: (1) laminated rubber bearing; (2) lead core rubber bearing; (3) friction pendulum seismic isolation bearing. The main disadvantages of these three types of bearings are: laminated rubber bearings can withstand large vertical loads, and have flexible stiffness characteristics similar to springs in ...
