A three-dimensional vibration isolation device

Abstract

The invention relates to a three-dimensional shock isolation device. The device comprises an upper cover plate, a horizontal shock isolation part, a vertical shock isolation part and a lateral steel plate, wherein the vertical shock isolation part comprises a transition connecting steel plate, and a core connecting part which is arranged below the transition connecting steel plate; the core connecting part is laterally obliquely provided with a plurality of channel steel damping devices by hinging; the other end of each channel steel damping device is hinged to the lateral steel plate; the plurality of channel steel damping devices under a static load state can support the core connecting part as well as keeping the core connecting part balanced; an adhering elastic laminating part is arranged below the core connecting part; a lead core column body passes through a hole in the adhering elastic laminating part; a hole is formed between the adhering elastic laminating part and the core connecting part; the lead core column body with steel threads is inserted into the hole to extrude the lateral plate to be integrated with the adhering elastic laminating part and the core connecting part; the channel steel damping devices under a dynamic load state are yielded and out of stability, and the rigidity is reduced to be zero, and the adhering elastic laminating part and the lead core column body can perform the longitudinal shock isolation.

Description

technical field [0001] The invention relates to a shock-isolation device, in particular to a three-dimensional shock-isolation device, which belongs to the technical field of building shock absorption. Background technique [0002] Since the Wenchuan Earthquake and Ludian Earthquake in my country, seismic isolation technology has been concerned and recognized by the engineering community for its excellent shock absorption effect, and has been widely used in the reinforcement of new structures and existing structures. The experience of major earthquakes at home and abroad shows that Multi-storey or even high-rise buildings using seismic isolation technology have withstood the test of strong earthquakes, and the safety of the structure can be guaranteed through the implementation of seismic isolation, which shows that seismic isolation is a shock-absorbing technology with good application prospects. [0003] The existing earthquake measurement research shows that the vertical s...
