Abstract

The invention relates to the technical field of seismic isolation, in particular to a steel plate / polyurethane laminated seismic-isolation support which comprises a support body. The support body is formed by alternately laminating and bonding steel plates and polyurethane elastomer plates. Compared with a steel plate / rubber laminated seismic-isolation support, the steel plate / polyurethane laminated seismic-isolation support is lower in production process, higher in quality and excellent in performance and can be used as a seismic-isolation structure of buildings, bridges, industrial equipment and valuable cultural relics. The invention further relates to a manufacturing method of the steel plate / polyurethane laminated seismic-isolation support.

Description

Technical field

[0001] The present invention relates to the field of seismic isolation technology, in particular to a laminated seismic isolation support using polyurethane elastomer plates instead of rubber plates in a steel / rubber laminated seismic isolation support. The laminated seismic isolation support can be used as a building, The seismic isolation structure of bridges, industrial equipment and valuable cultural relics; the present invention also relates to a manufacturing method of the laminated seismic isolation support. Background technique

[0002] At present, laminated seismic isolation bearings are widely used in the field of seismic isolation and vibration reduction, and the more mature ones are steel / rubber laminated seismic isolation bearings. The production process of the steel / rubber laminated shock isolation bearing is to laminate the unvulcanized rubber sheet with the intercalated steel sheet layer that has been bonded, and then place it in the mold for high ...
