The shock insulating device is low in cost, simple in structure, convenient to construct, high in pulling resistance and twisting resistance and obvious in shock-insulating effect.

Description

technical field [0001] The invention belongs to the technical field of shock absorption and isolation in structural engineering, and relates to a linear guide rail with a small friction coefficient, and two layers of vertical guide rails are arranged on the upper and lower layers, so as to meet the requirements of shock isolation in two vertical directions. Some auxiliary components such as springs for structural rigidity and dampers for controlling displacement and energy consumption form a complete shock-isolation device. The invention has low cost, strong tensile and torsion resistance, outstanding shock isolation effect, convenient construction and good development prospects. Background technique [0002] In the field of civil engineering at home and abroad, the seismic isolation technology of medium and low height buildings is approaching maturity. The main technologies are: rubber bearing isolation, friction sliding bearing isolation, and rolling isolation. There are ...

AI Technical Summary

Problems solved by technology

However, these current isolation devices at home and abroad have certain limitations, such as: the rubber bearing has low tensile capacity, torsion resistance, and vertical bearing capacity; The strength is low, the dynamic and static friction coefficient, arc shape and other parameters are not easy to determine, and the processing technology is complicated, generally only suitable for buildings with medium and low heights

Aiming at the problems of low vertical stiffness and small damping of rubber bearings, some experts have developed interlayer rubber pads and lead core rubber pads. Although the vertical stiffness and damping of these two isolation devices have been improved, their tensile capacity And torsion resistance has not been improved, it is still not practical for high-rise buildings and some high-flexible structures and equipment
