Abstract

The invention discloses a single-pulley bridge damping structure. The structure comprises a force transmission part arranged on the bottom of a girder and a damping reset part arranged between a pairof supporting base cushions. The middle of the damping reset part is connected with the force transmission part, and when the girder drivers the force transmission part to move horizontally and vertically, the force transmission part interacts with the damping reset part, so that the girder is reset. The single-pulley bridge damping structure is simple, low in cost, quick to construct and convenient to maintain and replace, the horizontal / vertical displacement of the girder can be limited, the girder can be automatically reset, the service life of a bridge is effectively prolonged, the passagesafety of pedestrians and vehicles is guaranteed, and the structure has good engineering application prospects.

Description

technical field [0001] The invention relates to the field of bridge anti-seismic and shock-absorbing technologies, in particular to a single pulley type bridge anti-shock structure. Background technique [0002] With the development of highway and bridge technology, the requirements for bridge shock absorption are getting higher and higher, especially in earthquake-prone areas, bridge shock absorption is particularly important. When an earthquake occurs, if there are no sufficient anti-seismic or shock-absorbing measures, the upper girder will undergo a large lateral displacement, causing damage to the upper girder. In severe cases, there will be a risk of girder falling, which will directly threaten the driving safety of vehicles on the bridge. The existing bridge shock-absorbing structure is mainly considered from the aspect of constraining the lateral displacement of the main girder, which can only limit the lateral displacement of the main girder to a certain extent; onc...
