Vibration isolation structure

Abstract

The invention provides a vibration isolation structure. The vibration isolation structure comprises a fourth fixing plate; a second sliding block is welded to a central shaft of the top of the fourthfixing plate; a blocking block is arranged on the outer side of the second sliding block; four third springs are welded to the top of the fourth fixing plate; a third fixing plate is welded to the other ends of the third springs; a through hole is formed in a central shaft of the top of the third fixing plate; the inner wall of the through hole is provided with a sliding groove; one end of the second sliding block penetrates through the through hole in one side of the third fixing plate; and the sliding groove of the inner wall of the through hole of one side of the third fixing plate is slidably connected with the second sliding block. Generally, a plurality of buffer structures are adopted by the vibration isolation structure for alleviating external impact force, the vibration isolationeffect is improved, thus, an upper layer building of the device is not damaged by external impact, and the vibration isolation capacity of buildings is improved.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a shock-isolation structure. Background technique [0002] Seismic isolation building refers to the use of seismic isolation technology to install seismic isolation devices at the base of the building or at a certain position to form a seismic isolation layer, which isolates the upper structure from the lower foundation, so as to consume seismic energy and avoid or reduce earthquakes. The energy is transmitted to the upper part, which can more effectively guarantee the safety of the upper structure, internal personnel and equipment. [0003] Seismic isolation is a new type of seismic-resistant form of building structures. A seismic isolation pad is placed on the top of a certain layer of the building to prevent the seismic action from being transmitted upwards, thereby achieving the effect of weakening the seismic reflection of the structure. [0004] When the cur...

AI Technical Summary

Problems solved by technology

[0004] When the current buildings are constructed, the anti-seismic ability must be considered, but the existing seismic isolation structures for buildings are expensive to manufacture and the anti-seismic ability is not strong.
