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 in conjunction with the accompanying drawings and embodiments.

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

[0028] see figure 1 , the steel plate / polyurethane laminated seismic isolation bearing includes a bearing main body 1, the bearing main body 1 is formed by alternately superimposing and bonding steel plates 2 and polyurethane elastomer plates 3, and the two outer layers of the bearing main body are Polyurethane elastomer sheet3. Both the thickness of the steel plate 2 and the polyurethane elastomer plate 3 are 20mm. It should be understood that the thickness of the steel plate and polyurethane elastomer plate can also be other values, such as other values ​​in 2-20 mm.

[0029] The following are several manufacturing methods of the above-mentioned...

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 invention relates to the field of shock isolation technology, in particular to a laminated shock-isolation support in which a polyurethane elastomer plate is used to replace the rubber plate in a steel plate / rubber laminated shock-isolation support, and the laminated shock-isolation support can be used as a building, The seismic isolation structure of bridges, industrial equipment and precious cultural relics; the invention also relates to the manufacturing method of this laminated seismic isolation bearing. Background technique [0002] At present, laminated seismic isolation bearings are widely used in the field of vibration isolation and vibration reduction, among which steel plate / rubber laminated seismic isolation bearings are more mature. 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 been bonded, and then put it int...
