Friction pendulum support with horizontal rotating function for building

Abstract

The invention relates to the technical field of building and bridge seismic mitigation and isolation, in particular to a friction pendulum support with a horizontal rotation function for a building. The friction pendulum support comprises an upper sliding plate, an upper support plate, a sliding block, a lower support plate and a lower sliding plate, the upper support plate is arranged at the bottom end of the upper sliding plate, the sliding block is connected to the bottom end of the upper support plate, the lower support plate is connected to the bottom end of the sliding block, and the lower sliding plate is arranged at the bottom end of the lower support plate. The friction pendulum support with the horizontal rotation function for the building has the beneficial effects that the structure is simple, installation is convenient, replacement and maintenance are easy, the construction cost is low, the safety performance is high, the friction pendulum support is economical and practical, the friction pendulum support has a better shock absorption and isolation effect compared with existing bridges and building supports, and the friction pendulum support can be widely applied to projects such as bridges and buildings.

Description

Technical field[0001]The present invention relates to the field of building, and the bridge reduction field, and more particularly to a frictional arrangement of a building with horizontal rotational function.Background technique[0002]The frictional flashes of the friction beam is developed by the US Earthquake Protection System (EPS) in 1985 and is first used in the building structure of the house. The essence of the friction shade of the frictional shock shock is also a frictional damping support, but it is the normal function of the mount to achieve the friction of the two curved surfaces. When the upper and lower part of the building occurs relatively, the swing is moved as the pendulum. The horizontal movement produces a vertical lift of gravity, such as ignores friction, the motion equation of the system approximates a level of equal presence, and the length of the spherical surface is the radius of curvature. By changing the radius of the curvature of the spherical spherical ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems in the prior art that the currently used friction pendulum type shock-isolation bearings have two types: spherical and cylindrical. When the bearing rotates, the axial direction needs to impose displacement constraints separately, and the direction is single, which cannot meet the seismic requirements in other directions
