Problems solved by technology

When the bonding between the under-vulcanized rubber inside the rubber and the inserted steel plate is poor, or the horizontal elastic constant of the product is too different from the design target value, the natural vibration frequency will change, and the expected shock isolation effect will not be achieved. It is quite difficult to set the vulcanization conditions of the layer rubber
Therefore, the production process of the steel plate / rubber laminated seismic isolation bearing requires high requirements and the quality is difficult to control

Embodiment Construction

[0026] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] figure 1 Shown is one embodiment of the steel plate / polyurethane laminated seismic isolation support of the present invention.

[0028] See figure 1 The steel plate / polyurethane laminated seismic isolation support includes a support main body 1 which is formed by alternately superposing and bonding steel plates 2 and polyurethane elastomer plates 3, and the two outer layers of the support main body are both Polyurethane elastomer board 3. The thickness of the steel plate 2 and the polyurethane elastomer plate 3 are both 20 mm. It should be understood that the thickness of the steel plate and polyurethane elastomer plate may also have other values, such as other values ​​in 2-20 mm.

[0029] The following are several manufacturing methods for the above-mentioned steel plate / polyureth...

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 ...
