Rolling isolation bearing

Abstract

The invention discloses a rolling isolation bearing. The rolling isolation bearing comprises a rolling plate and a bottom box, and the bottom box is provided with an open top. Grooves parallel to theY axis are formed in two opposite sides of the bottom of the bottom box, and the grooves are separately provided with preloaded spring sets. A boss is arranged between the grooves, a plurality of horizontal rollers parallel to each other are arranged on the upper surface of the boss, and the axes of the horizontal rollers are parallel to the X axis. The rolling plate is mounted on the bottom box,and the bottom surface of the rolling plate is in contact with the horizontal rollers. When the rolling isolation bearing is subjected to the lateral load force, the rolling plate is in contact with the horizontal rollers, the damage of the lateral load force to the upper structure of a building is dispersed by the slip generated between the rolling plate and the bottom box. When the bottom box isdeformed by the lateral load force, the preloaded spring sets can provide elastic force to overcome the deformation, so the rolling isolation bearing is not prone to generating residual deformation after being subjected to the lateral load force, and the preloaded spring sets can drive the rolling plate to reset.

Description

technical field [0001] The invention relates to a building shock-isolation structure, in particular to a rolling shock-isolation bearing. Background technique [0002] Vibration can be seen everywhere in our daily life. Whether it is a serious geological disaster—an earthquake, or the vibration generated by a car passing by a bridge, it will cause varying degrees of damage to the main structure of the building. Since the seismic isolation technology was proposed in modern times, people's research on seismic isolation technology has never stopped. Seismic isolation technology is a technology in which the upper structure of a building is flexibly connected to the foundation through a seismic isolation layer. Since the seismic isolation layer has the functions of "shock isolation" and "shock absorption", the transverse load force generated by the shock wave on the building superstructure during an earthquake is suppressed. Distributed to the seismic isolation layer to achieve ...

Problems solved by technology

[0003] At present, the commonly used types of isolation mainly include interlayer rubber pad isolation and sliding friction isolation, in which the sandwich rubber pad isolation bearing has residual deformation after being subjected to a transverse load, and the vertical load capacity of the interlayer rubber pad isolation bearing The capacity is limited; the displacement generated by the sliding friction isolation bearing is often unable to recover in time when it is subjected to a transverse load, and it is easy to roll when it is subjected to severe shocks
