Building seismic isolation structure

Abstract

The invention discloses a building seismic isolation structure. The building seismic isolation structure comprises a fourth fixing plate; a second sliding block is welded to the central axis of the top of the fourth fixing plate; a stopping block is arranged on the external side of the second sliding block; third springs are welded to the top of the fourth fixing plate; the number of the third springs is four; a third fixing plate is welded to the other ends of the third springs; a through hole is formed in the central axis of the top of the third fixing plate; a slide groove is formed in theinternal wall of the through hole; one end of the second sliding block penetrates through the through hole in one side of the third fixing plate; and the second sliding block is slidingly connected tothe slide groove in the internal wall of the through hole in one side of the third fixing plate. In general, the building seismic isolation structure buffers an outside impact force by using multiplebuffering structures so that the seismic isolation effect is improved; and therefore, a superstructure cannot be damaged due to the impact of the outside force so that the earthquake prevention capacity of a building is improved.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a seismic isolation structure for construction. 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. ...

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.
