Highway bridge shock absorption supporting frame

Abstract

The invention relates to the technical field of highway bridges and discloses a highway bridge shock absorption supporting frame which comprises a highway body. 20-30 supporting rods at equal intervals are fixedly connected to the top front face and the back face of the highway body, and a first shock absorption mechanism is arranged between every two adjacent supporting rods. Problems of poor buffering effects, failure in bridge protection, inconvenience in use and damages of pedestrians and vehicles in traveling after impact on highway bridge shock absorption supporting seats are solved. Under the elastic action of buffering springs in annular arrangement, corrugated elastic pipes shrink by force interaction and decomposition; first supporting rods and second supporting rods are capableof moving slightly to realize force offset, buffering effects of the highway bridge shock absorption supporting frame are improved, and convenience in use is achieved without damages of pedestrians and vehicles in traveling.

Description

technical field [0001] The invention relates to the technical field of highway bridges, in particular to a vibration-damping support for highway bridges. Background technique [0002] Highway bridges are generally composed of several parts such as roadbed, road surface, bridge, tunnel engineering and traffic engineering facilities. [0003] Bridge bearings are important structural components connecting the bridge superstructure and substructure. It can reliably transmit the reaction force and deformation (displacement and rotation angle) of the bridge superstructure to the bridge substructure, so that the actual stress of the structure is consistent with the calculated theoretical diagram. Shock absorbers are used on the bridge supports. [0004] Chinese patent CN201720388458.8 discloses a bridge damping bearing, including a bridge body and a support column fixedly installed at the bottom of the bridge body. The lower surface of the bridge body is fixedly equipped with a s...

Problems solved by technology

[0007] Aiming at the deficiencies in the prior art, the present invention provides a road bridge damping support, which solves the problem that after the shock absorption of the road bridge damping support is impacted, the cushioning effect is poor, the bridge cannot be well protected, and it is not convenient to use , which will cause harm to people and vehicles on the road
