Embodiment Construction

[0036] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0037] figure 1 Shown is one embodiment of the fiber-reinforced epoxy / polyurethane laminate seismic isolation bearing of the present invention.

[0038] see figure 1 , the fiber-reinforced epoxy resin / polyurethane laminated seismic isolation bearing includes a bearing main body 1, the bearing main body 1 is formed by alternately superimposing and bonding fiber-reinforced epoxy resin boards 2 and polyurethane elastomer boards 3, and the Both outer layers of the main body of the support are polyurethane elastomer plates 3 . The thicknesses of the fiber-reinforced epoxy resin plate 2 and the polyurethane elastomer plate 3 are both 20mm. It should be understood that the thickness of the fiber-reinforced epoxy resin board and the polyurethane elastomer board can also be other values, su...

Abstract

The invention relates to the technical field of seismic insulation, and particularly relates to a fiber reinforced epoxy resin / polyurethane laminated seismic insulation support. The support comprises a support body which is formed by alternately overlaying and bonding fiber reinforced epoxy resin plates and polyurethane elastic body plates. The support is low in cost and simple in construction technology, with the pressure stress limiting value being smaller than that of a laminate steel plate rubber support, and is applicable to low-rise buildings, multi-rise buildings, bridges, industrial equipment and valuable cultural objects in small towns, villages and mountainous areas. The invention also discloses a manufacture method of the fiber reinforced epoxy resin / polyurethane laminated seismic insulation support.

Description

technical field [0001] The invention relates to the field of shock isolation technology, in particular to a laminated shock-isolation bearing mainly composed of fiber-reinforced epoxy resin plates and polyurethane elastomer plates alternately stacked, the laminated shock-isolation support can be used as a low-rise building, The seismic isolation structure of multi-storey buildings, bridges, industrial equipment and precious cultural relics; the invention also relates to the manufacturing method of the laminated seismic isolation bearing. Background technique [0002] In the field of vibration isolation and vibration reduction, laminated seismic isolation bearings have been widely used, and the most mature laminated seismic isolation bearings are steel plate / rubber laminated seismic isolation bearings. The production process of the steel plate / rubber laminated seismic isolation bearing is to bond the unvulcanized rubber sheet with the intercalated steel plate layer that has b...
