Curvature variable self-reset and protection three-dimensional shock damping and insulation energy dissipating support

Abstract

This invention relates to a variable curvature self-reset protecting three-dimensional shock mount, which belongs to the shock insulation control and vibration control fields. The structure of the mount is: coating the frictional layer on the variable curvature chassis and its surface, the lower connection board and the limiting composition board; setting high elastic rubber ring between the chassis and the limiting composition board; setting the slide block in the center of the chassis and applying middle-connection board on it, wherein the convex axial and center arbor is arranged on the middle-connection board, the convex axial is covered the disk spring superposition, and between the superposition is arranged damping material, outside the superposition is covered with steel ring; between the center arbor is arranged damper, the convex axial and center arbor plunge the upper-connection board and have gap distance to the board. The invention can guard and repress horizontal and vertical earthquake wave at the same time, and eliminate the disadvantage of torsion and P-delta effect to the supperstructure, in addition to limiting protection.

Description

technical field [0001] The invention relates to a self-resetting, variable-curvature three-dimensional shock-isolation energy-consuming bearing, which is mainly used for foundation shock-isolation of houses, bridges and other buildings, and can also be used for vibration-isolation and shock-reduction of instruments and equipment, belonging to structural shock-isolation control and vibration control technology. Background technique [0002] In the design and construction of bridges and building structures, the impact of earthquakes and vibrations on engineering structures must be taken into account. The support is a structural shock isolation device widely used in engineering construction. It not only transfers the weight of the upper structure of the building structure to the lower structure, but also has the function of shock absorption and isolation. [0003] Seismic isolation is the earliest researched and most widely used shock-absorbing technology in structural vibrati...
