Embodiment Construction

[0022] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. This embodiment is based on the technical solution of the present invention and provides detailed implementation methods, but the scope of protection of the present invention is not limited to the following embodiments.

[0023] The shock-absorbing structure based on the bridge pad stone of the present invention is installed on the pad stone supporting the main beam bearing at the two ends of the main beam and the cover beam, and includes an upper fixing part, a pair of lower fixing parts and a shock-absorbing reset part , the shock-absorbing reset part is connected between the upper fixing part and the lower fixing part.

[0024] Specifically, such as figure 1 , 2 As shown, the upper fixing part includes seven pre-embedded ear plates 1.1 located at the bottom of the main beam M. The thickness of the pre-embedded ear plates 1.1 is 1-2 cm, and the pr...

Abstract

The invention discloses a shock-absorbing structure based on a bridge cushion stone. The shock-absorbing structure comprises cushion stones symmetrically arranged at the two ends of a cover beam and used for supporting a main beam support, and further comprises an upper fixing part arranged at the bottom of a main beam, a lower fixing part arranged around each cushion stone, and a shock-absorbingreset part. The two ends of the shock-absorbing reset part are connected with the lower fixing parts, and the center of the shock-absorbing reset part is connected with the upper fixing part and usedfor bridge shock absorbing and resetting the main beam with transverse displacement. The shock-absorbing structure has the advantages of simple structure, low manufacturing cost, rapid construction and convenient maintenance and replacement, can not only limit the transverse displacement of the main beam, but also enables the main beam to be autonomously reset, effectively improves the service life of the bridge, guarantees the passing safety of people and vehicles, and has a good engineering application prospect.

Description

technical field [0001] The invention relates to the technical field of bridge anti-seismic shock absorption, in particular to a shock-absorbing structure based on bridge pad stones. 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...
