Abstract

The invention discloses a bamboo-plastic fiber composite plate/rubber sheet laminated earthquake-isolation bearing and a manufacturing method of the earthquake-isolation bearing. The earthquake-isolation bearing comprises a bearing main body, wherein the bearing main body comprises rubber sheets and bamboo-plastic fiber composite plates which are alternatively laminated, two outer layers of the bearing main body are rubber sheets and the bearing main body comprises 1-10 layers of bamboo-plastic fiber composite plates. The manufacturing method of the earthquake-isolation bearing comprises the following steps: S1, manufacturing the bamboo-plastic fiber composite plates; S2, manufacturing the rubber sheets; and S3, manufacturing the bearing main body. The bamboo-plastic fiber composite plates can replace steel plates, the rubber sheets and the bamboo-plastic fiber composite plates are alternatively laminated and subjected to vulcanization molding to obtain the novel bamboo-plastic fiber composite plate/rubber sheet laminated earthquake-isolation bearing capable of isolating the 1-5 floors of buildings from earthquake in villages, small towns and mountain areas. The earthquake-isolation bearing has the advantages of light weight and low cost and has good application prospects in the field of earthquake-isolation of 1-5 floors of low-rise buildings in the villages, the small towns and the mountain areas.

Description

technical field [0001] The invention relates to the field of seismic isolation technology, in particular to a bamboo-plastic fiber composite board / rubber sheet laminated seismic isolation bearing, which can be used as a seismic isolation structure for buildings in villages, towns and mountainous areas; the invention also relates to this A method for manufacturing a laminated shock-isolation bearing. Background technique [0002] Laminated vibration isolation bearings have been widely used in the field of vibration isolation and vibration reduction. At present, the more mature seismic isolation bearing in practical application is the steel plate / rubber laminated seismic isolation bearing, which has high cost and heavy weight, and is generally used in the field of seismic isolation of buildings with more than 5 floors. The proportion of 1-5 storey low-rise buildings in villages, towns and mountainous areas in my country is very large, and it is difficult to popularize and app...
