A three-dimensional shock-isolation bearing

Abstract

The invention relates to the field of engineering structure shock reduction and insulation, and provides a three-dimensional shock insulation support. The three-dimensional shock insulation support comprises a middle supporting platform, an upper supporting platform, a critical unlocking vertical shock insulation unit formed by a structure between the middle supporting platform and the upper supporting platform, and a horizontal shock insulation unit is formed between the middle supporting platform and a lower supporting platform, wherein through the critical unlocking vertical shock insulation unit, the effect that the three-dimensional shock insulation support has the strong vertical shock insulation function can be ensured, and meanwhile, the vertical bearing capacity and stability of the three-dimensional shock insulation support can be ensured. In addition, the horizontal shock insulation unit has the functions of both a horizontal sliding plate support and a damper, so that spaces inside the supporting platforms are sufficiently utilized, and the horizontal shock insulation unit can achieve energy dissipation and shock isolation under earthquake action in a horizontal plane in any direction; and further, the horizontal shock insulation unit has high vertical bearing capacity and drawing resistance when dealing with the combined action of a horizontal earthquake and a vertical earthquake, and can be resistant to swinging and overturning when applied to high-rise buildings.

Description

technical field [0001] The invention relates to the field of shock absorption and isolation of engineering structures, in particular to a three-dimensional shock isolation support. Background technique [0002] Shock-isolation (vibration) technology is a technology used in buildings, bridges and other structures in recent years. Its characteristics are: by installing energy-dissipating shock-isolation devices at appropriate positions in the structure, it can effectively block and consume earthquakes transmitted from the foundation to the upper part. The energy of the structure can reduce the response of the structure under dynamic load, thereby improving the safety and overall economy of the structure. [0003] In the prior art, there are few studies on isolation of vertical vibration caused by vertical earthquakes. Among them, the difficulty in the vertical seismic isolation design of buildings lies in how to increase the vertical period of the isolated structure while ens...
