Problems solved by technology

However, in areas where geological subsidence is prone to occur, the lower vibration isolator of the floating slab is required to have a large height adjustment capability, so the currently used floating slab vibration isolator plus adjustment backing plate is difficult to meet the requirements of the above-mentioned areas
In addition, this kind of vibration isolator is prone to inclination after the foundation changes, resulting in uneven stress on the elastic elements, which is very easy to cause damage

Abstract

The invention relates to a vibration isolator for a rail traffic floating slab, comprising a lower support, a rubber vibration reduction ring, a height adjusting screw, a height adjusting nut and a coupling flange. The lower support is disposed on a base, a concave groove is disposed on the lower support, and the rubber vibration reduction ring is disposed in the concave groove. The head of the height adjusting screw is disposed in the vibration reduction ring, the screw extends upwards and has male thread. The height adjusting nut is connected with the height adjusting screw by female threadthereof. The coupling flange is mounted on the height adjusting nut and is connected with the floating slab to make the vibration isolator to support the floating slab. The vibration reduction effectof the invented vibration isolator is better than that of the traditional metal spring vibration isolator, and can satisfied road bed height adjustment request better.

Description

technical field [0001] The invention relates to the technical field of rail transit vibration reduction and noise reduction, in particular to a vibration isolator for a rail transit floating plate vibration isolation system. Background technique [0002] At present, among the vibration and noise reduction methods of urban rail transit, the floating plate vibration isolation system has the best vibration reduction effect, and has been widely used in the construction of rail transit in various cities in China. However, the vibration isolators currently used in floating slabs are mainly metal spring vibration isolators, which have obvious standing wave effects, and the transverse and longitudinal stiffness cannot be controlled, which cannot meet the requirements of track deformation. This kind of metal spring vibration isolator is generally used in ordinary geological areas, that is, areas with relatively stable geological conditions. The height adjustment is not considered, an...
