Combined three-dimensional shock insulation support

Abstract

The invention belongs to the technical field of shock absorption devices, and discloses a combined three-dimensional shock insulation support which comprises a first connecting plate, a second connecting plate and a supporting part located between the first connecting plate and the second connecting plate, and a plurality of buffer mechanisms are further arranged between the first connecting plateand the second connecting plate. The supporting part comprises a plurality of rubber layers, a plurality of steel plates and a plurality of protective sleeves, the rubber layers and the steel platesare sequentially stacked at intervals, turned edges are arranged on the steel plates, the turned edges are buckled with the rubber layers, the protective sleeves wrap the peripheries of the rubber layers and the steel plates, and each buffer mechanism comprises a movable hinge, a damper, a connecting rod and a pin shaft. By means of the laminated structure of the steel plates and the rubber and the design of the flanged steel plates, the vertical and horizontal shock insulation effects are efficiently improved, the buffering mechanisms are stressed and deformed to effectively achieve the shockabsorption and energy consumption effects, and the problems that a traditional shock insulation support is insufficient in horizontal and vertical shock insulation capacity and insufficient in stability at the same time are solved.

Description

technical field

[0001] The invention relates to the technical field of shock absorbing devices, in particular to a combined three-dimensional shock-isolation support. Background technique

[0002] Seismic isolation technology is a vibration control technology developed in recent years and applied to engineering structures. Its characteristic is that it can significantly reduce the impact of earthquakes or other vibrations on the upper structure to effectively protect the safety of the upper structure.

[0003] Although the research on three-dimensional seismic isolation has made some progress in recent years, there are few practical projects for effective application; under the action of three-dimensional earthquake, especially in the environment where the vertical load and stiffness of building structures are required It is difficult, and the research at this stage is mainly rubber bearings, elastic slide bearings, friction pendulum bearings, etc., although they have been w...
