Abstract

The invention relates to a fixed-type vibration absorption and noise reduction rubber support for a rail transit bridge. The fixed-type vibration absorption and noise reduction rubber support for the rail transit bridge comprises an upper support plate (2) and a lower support plate (8), wherein four upper anchor bars (1) are arranged on the upper support plate (2), four lower anchor bars (5) are arranged on the lower support plate (8), four lower wedge-shaped fixed blocks (7) are arranged on the lower support plate (8), the four lower wedge-shaped fixed blocks (7) are correspondingly arranged, four upper wedge-shaped fixed blocks (4) corresponding to the four lower wedge-shaped fixed blocks (7) are respectively arranged at the bottom of the upper support plate (2), and vulcanized rubber plates (6) are respectively arranged between the corresponding lower wedge-shaped fixed blocks (7) and upper wedge-shaped fixed blocks (4). The fixed-type vibration absorption and noise reduction rubber support for the rail transit bridge has the advantages that the vertical rigidity and the vertical vibration absorption damping are guaranteed to be enough and the weak vibration phenomenon produced by rails during operation is weakened.

Description

Technical field [0001] The present invention involves a rubber branch. It is more specifically involved in a fixed vibration vibration and noise reduction rubber support for rail transit bridges. Background technique [0002] At present, in the field of building bridges, there are certain research on the strong vibration of earthquakes and developed corresponding earthquake -resistant products.However, with the popularity of rail transit and other rail transit in urban lights, while bringing convenient transportation to the city, it also has the impact of vibration and noise on the rail buildings and residents.The weak vibrations and noise have a negative impact on the orbit surrounding buildings and the human body. Therefore, higher requirements have been put on vibration reduction and noise reduction in the construction of rail transit.However, the existing rail transit bridge vibration and noise reduction device during the operation of the train brake and high -speed turning, ...
