Anti-buckling low-frequency vibration isolation rubber support

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...
