Problems solved by technology
[0003] However, in view of the different requirements of different bridges for seismic isolation, it is often necessary to customize different seismic isolation bearings. The horizontal shear force that the same seismic isolation bearing can withstand has been determined at the factory. It is impossible to further adjust the needs of different bridges on site, and the scope of use is very limited

Embodiment Construction
[0027] Such as Figure 1-3 As shown, a high-damping shock-absorbing and isolating bearing of this embodiment includes an upper steel plate 1 , a bearing body 2 and a lower steel plate 3 . Such as Figure 4 As shown, the support body 2 of this embodiment includes a rubber body 4, a top steel plate 5, a stiffening steel plate 6 and a bottom steel plate 7. The rubber body 4 is sandwiched with six layers of stiffening steel plates 6, and the top steel plate 5 is fixedly arranged on the rubber body 4. The bottom steel plate 7 is fixedly arranged on the bottom surface of the rubber body 4, the upper support steel plate 1 is detachably arranged on the top surface of the top steel plate 5 through connecting bolts, and the lower support steel plate 3 is detachably arranged on the bottom surface through connecting bolts. The bottom surface of the steel plate 7.

The invention discloses a high-damping shock absorption and isolation support which comprises a support upper steel plate, a support body and a support lower steel plate. The support body comprises a rubber body, a top steel plate, stiffening steel plates and a bottom steel plate, a plurality of layers of stiffening steel plates are arranged in the rubber body in a clamped mode, the top steel plate is fixedly arranged on the top face of the rubber body, the bottom steel plate is fixedly arranged on the bottom face of the rubber body, a plurality of inserting holes are formed in the support body in the vertical direction, each inserting hole at least penetrates through the top steel plate, the rubber body and the stiffening steel plates, an inserting tenon is detachably inserted in each inserting hole, the position, corresponding to the place between the adjacent stiffening steel plates, of each inserting tenon is arranged to be a weak portion used for bearing the set horizontal shear force namely being broken off. The high-damping shock absorption and isolation support is adjustable in rigidity, and can perform classification cutting off, meets the requirement of horizontal shear force resistance for different bridges on site, and the rigidity of the support can be conveniently and rapidly adjusted.
Description
technical field [0001] The invention relates to the technical field of bridge support design, in particular to a high-damping shock-absorbing and isolation support. Background technique [0002] The support refers to the supporting part used to support the weight of the container or equipment and fix it in a certain position, and it needs to bear the vibration and earthquake load during operation. In the bridge structure, the bridge bearing should not only meet the requirements of normal service loads such as temperature, braking force, and concrete shrinkage and creep, but also meet the requirements of accidental loads such as earthquakes, including vertical loads and horizontal shear forces. In the technical field of bridge shock-isolation, the easier and more effective shock-absorbing method is to adopt shock-isolation bearings, such as rubber shock-isolation bearings and lead core shock-isolation bearings. The rubber shock-absorbing bearing has sufficient vertical stiff...
