Problems solved by technology

[0002] With the process of urbanization and the rapid development of modern industry, all kinds of rail and road traffic are becoming more and more dense, and there are more and more production activities with exciting effects. The comfort of facilities, and it will cause long-term cumulative damage or fatigue to old structures, historical buildings and valuables, and it will also affect the normal use of vibration-sensitive instruments and equipment
[0003] It is difficult for traditional vibration isolation bearings to meet the requirements of high bearing capacity and low frequency vibration isolation at the same time. Low stiffness and high flexibility bearings often produce buckling instability under high load. Difficult to satisfy at the same time

Embodiment 1

[0045] see Figure 1-Figure 16 , the anti-buckling low-frequency vibration-isolation rubber bearing of the present invention includes a rubber bearing body 1, an upper connecting steel plate 2 arranged at the upper end of the rubber bearing body 1, and a lower connection plate arranged at the lower end of the rubber bearing body 1. The steel plate 3 and the anti-seismic sleeve 4 arranged in the rubber bearing body 1, wherein the rubber bearing body 1 includes the upper sealing layer steel plate 5, the lower sealing layer steel plate 6, and the upper sealing layer steel plate 5 and the lower sealing layer steel plate The multi-layer laminated rubber 8 between the sealing steel plates 6, wherein the laminated rubber 8 and the inner steel plate 5 are connected into one body through high-temperature vulcanization bonding; an inner steel plate is arranged between two adjacent layers of laminated rubber 8 7. The anti-seismic sleeve 4 is vertically arranged in the rubber bearing body...

Embodiment 2

[0084] see Figure 17 The difference between this embodiment and Embodiment 1 is that the rubber layer 10 is a thin rubber ring, and the thin rubber ring is set on the anti-seismic sleeve 4 .

[0085] All the other structures are implemented with reference to Example 1.

Embodiment 3

[0087] see Figure 18 The difference between this embodiment and Embodiment 1 is that one of the multiple anti-seismic sleeves 4 vertically penetrates the upper connecting steel plate 2 sequentially from the axial center of the rubber bearing body 1 , the rubber bearing body 1 and the lower connecting steel plate 3, the rubber bearing body 1 is provided with a through hole at the position in contact with the shockproof casing 4, a rubber layer 10 is arranged in the through hole, and the rubber layer 10 is implemented with reference to the rubber layer 10 in Example 1.

[0088] And other anti-seismic sleeves 4 are distributed along the circumferential direction of the rubber bearing body 1, and vertically run through the upper connecting steel plate 2, the rubber bearing body 1 and the lower connecting steel plate 3 in sequence; A through hole is provided at the contact position of the anti-seismic sleeve 4 , and a rubber layer 10 is arranged in the through hole, and the rubbe...

Abstract

The invention discloses an anti-buckling low-frequency vibration isolation rubber support comprising a rubber support body and anti-seismic casing pipes arranged in the rubber support body. Laminatedrubber is adopted for the rubber support body. The low rigidity required by low-frequency vibration isolation is achieved by increasing the thickness of the rubber. The anti-seismic casing pipes are embedded in the support in the vertical direction and sequentially penetrate through the rubber support body from top to bottom, a restraining effect is achieved for the high-flexibility rubber supportbody in the horizontal direction, an anti-buckling function is provided for the rubber support body under the vertical large-load effect, and a horizontal earthquake resistance function is also provided for the support. Rubber layers or isolation gaps are arranged between the anti-seismic casing pipes and the rubber support body or between the anti-seismic casing pipes to avoid rigid contact, andthe environment vibration spreading route achieved through a rigid contact face is isolated. By means of the anti-buckling low-frequency vibration isolation rubber support, low-frequency vibration isolation of environment vibration can be achieved, high bearing stability and anti-seismic capacity can also be ensured, and the anti-buckling low-frequency vibration isolation rubber support can be used for vibration isolation of civil engineering structures and all types of instruments and equipment.

Description

technical field [0001] The invention relates to the technical field of building structure engineering, in particular to a buckling-resistant low-frequency vibration-isolation rubber bearing. Background technique [0002] With the process of urbanization and the rapid development of modern industry, all kinds of rail and highway traffic are becoming more and more dense, and there are more and more production activities with exciting effects. It will not only cause long-term cumulative damage or fatigue to old structures, historical buildings and valuables, but also affect the normal function of vibration-sensitive instruments and equipment. [0003] It is difficult for traditional vibration isolation bearings to meet the requirements of high bearing capacity and low frequency vibration isolation at the same time. Low stiffness and high flexibility bearings often produce buckling instability under high load. Difficult to satisfy well at the same time. For the vibration isola...
