Laminated support for seismic isolation of low-rise buildings and manufacturing method thereof

Abstract

The invention discloses a laminated support for seismic isolation of low-rise buildings, which comprises a main body of the support and an outer protective layer wrapping the main body of the support, wherein the main body of the support comprises an upper sealing plate layer, a middle layer and a lower sealing plate layer The middle layer includes at least two layers of rubber layers and at least one layer of bamboo-plastic composite board layers alternately superimposed and fixed with the same horizontal cross-sectional shape and size; the thickness of the upper sealing board layer and the lower sealing board layer is greater than that of the rubber layer and the lower sealing board layer The thickness of the bamboo-plastic composite board layer; the upper sealing board layer and the upper end surface of the middle layer are superimposed and fixed, and the lower sealing board layer and the lower end surface of the middle layer are superimposed and fixed. The invention also relates to a method of manufacturing such a laminated support. The invention has the advantages of simple process, controllable quality, low cost of materials and processing, light weight and convenient installation, and has good application prospect in low-rise buildings, especially in the field of shock isolation of low-rise buildings in rural areas.

Description

technical field [0001] The invention relates to a laminated bearing for earthquake isolation, in particular to a laminated bearing for earthquake isolation of low-rise buildings. It belongs to the technical field of shock-isolation bearings. The invention also relates to a method of manufacturing such a laminated support. 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 bearings in practical application are steel plate / rubber laminated seismic isolation bearings. Put it into the mold and vulcanize at high temperature (Zhao Ruishi. The vulcanization process and thermal analysis of the laminated rubber seat for seismic isolation [J]. World Rubber Industry, 2003, 2: 36-41). Although the steel plate / rubber laminated seismic isolation bearing has excellent performance, its manufacturing process is complicated, the cost is high, an...

AI Technical Summary

Problems solved by technology

Although the steel plate / rubber laminated seismic isolation bearing has excellent performance, its manufacturing process is complicated, the cost is high, and the weight is relatively large, so it is generally used in the field of high-rise building isolation

Low-rise buildings with 1-3 floors in rural areas in my country account for a large proportion, and it is difficult to popularize and apply steel plate / rubber laminated seismic isolation bearings. At the same time, the seismic design standards for rural buildings in China are generally low. A large number of casualties and property losses are caused, so there is an urgent need to develop new types of shock-isolating bearing products with lower development costs, lighter weight, and easy installation
