Abstract

A one-way slide type vibration and noise reduction rubber support of rail transit bridge comprises an upper support plate (2) and a lower support plate (8), wherein the lower wedge fixing block I (5) and the lower wedge fixing block III (10) on the lower support plate (8) are opposite to each other, the lower wedge fixing block II (7) and the lower wedge fixing block IV (11) on the lower support plate (8) are opposite to each other, the bottom of the upper support plate (2) is correspondingly provided with four upper wedge fixing blocks (4), a vulcanized rubber plate I (6) is disposed between the lower wedge fixing block I (5) and the corresponding upper wedge fixing block (4), a vulcanized rubber plate II (12) is disposed between the lower wedge fixing block II (7) and the corresponding upper wedge fixing block (4), a vulcanized rubber plate III (13) is disposed between the lower wedge fixing block III (10) and the corresponding upper wedge fixing block (4), and a vulcanized rubber plate IV (14) is disposed between the lower wedge fixing block IV (11) and the corresponding upper wedge fixing block (4). The one-way slide type vibration and noise reduction rubber support has the advantages that sufficient vertical rigidity and vertical vibration reduction damping are guaranteed, and weak vibration of rails during operation is weakened.

Description

technical field

[0001] The invention relates to a rubber bearing, more specifically to a one-way sliding vibration-reducing and noise-reducing rubber bearing of a rail transit bridge, and belongs to the technical field of bridge vibration reduction and isolation. Background technique

[0002] At present, in the field of seismic isolation of buildings and bridges, there has been some research on strong vibrations such as earthquakes and corresponding seismic products have been developed. However, with the popularization of rail transit such as urban light rail and subway, it not only brings convenience to the city, but also brings vibration and noise to the buildings and residents around the rail. The weak vibration and noise generated have a negative impact on the buildings around the track and the human body. Therefore, higher requirements for vibration and noise reduction are put forward in the construction of rail transit. However, the existing rail transit bridge vibrat...
