Abstract

The invention relates to the technical field of engineering structure shock isolation, in particular to a slip device for a shock isolation structure. The device includes two sets of sliding assemblies arranged horizontally from up down. The two sets of sliding assemblies are perpendicular with each other. Each set of sliding assembly includes a sliding block and a sliding rail. The sliding blockis slidably connected with the sliding rail. The upper sliding block is connected with the lower sliding block through a flexible connecting piece. The flexible connecting piece is a shape memory alloy wire rope. According to the invention, the displacement requirements of the structure on the horizontal directions are met through the upper and lower groups of sliding assemblies perpendicular witheach other; according to the device, the vertical resistance-to-tensile capability between the upper and lower structures can be provided through the shape memory alloy wire rope to make up for the poor resistance to tensile of the shock isolation device. Meanwhile, orthogonal sliding assemblies are arranged to ensure that the mechanical properties of the shock isolation layer of the structure will not be affected. The device has the advantages of simple structure, fast assembly, and has good application prospect in shock insulation engineering with remarkable resistance-to-tensile energy consumption requirements in high-rise buildings, special-shaped buildings, oblique bridges and bent bridges and the like.

Description

technical field [0001] The invention relates to the technical field of seismic isolation of engineering structures, in particular to a sliding device for seismic isolation structures. Background technique [0002] In recent years, with the rapid advancement of urbanization and social modernization in my country, the rapid increase in population density and the sharp increase in social wealth, the attention of all walks of life to the seismic performance of engineering structures including buildings, bridges, roads, and pipelines has increased significantly. How to further improve the overall earthquake resistance and disaster prevention ability of the structure on the existing basis and meet the higher requirements of human beings for safety, comfort, and economy are currently hot issues in the field of earthquake resistance of engineering structures. [0003] The basic principle of structural shock absorption is to reduce the horizontal stiffness of the structure, prolong t...
