Bridge with anti-seismic pins

Abstract

The invention belongs to the technical field of bridge anti-seismic devices, and discloses a bridge with anti-seismic pins, a pin block is poured on the upper side of a pier, and the anti-seismic pins are fixed on the pin block; the anti-seismic pins are arranged in an upper bridge frame groove, and the upper bridge frame groove is fixed on the bridge frame; a buffering block is installed on the upper side of the pier, and a buffering pad is arranged on the upper side of the buffering block; each anti-seismic pin is provided with a shaft body, and a lower side fixing plate and an upper side fixing plate are arranged at the lower end of the shaft body; a spring is installed on the upper side of the upper side fixing plate, and the upper side of the spring is connected with a connecting round block. The pin block is poured on the upper side of the pier, the anti-seismic pins are poured on the pin block, dislocation between the damping structure and the upper bridge frame can be avoided, repairing can be conducted in time, and the safety of the bridge is improved. Through the arrangement of the anti-seismic pins, certain disturbance is achieved while the connecting effect is achieved, and the anti-seismic pins are prevented from being damaged. Due to the fact that a hydraulic cylinder is good in corrosion resistance, compact in structure, large in damping force and small in friction control resistance, the anti-seismic effect is improved.

Description

technical field [0001] The invention belongs to the technical field of bridge anti-seismic devices, in particular to a bridge with anti-seismic pins. Background technique [0002] At present, my country's topography is complex. In order to connect various regions and make the economic and social development of each region stable, the bridge structure has played an extremely important role. Because the weight of the bridge is quite large and its function is extremely important, it is necessary to ensure that its quality meets the relevant national standards during the design process of the bridge. It must fully consider its adaptability, stability and integration with the environment. The structural quality can resist large-scale natural disasters and ensure the safety of people's lives and property. [0003] Shock-absorbing and isolation technology is the abbreviation of building shock-isolation technology and building shock-absorbing technology. By adopting certain scienti...

Problems solved by technology

On the one hand, if we want to separate the bridge structure from the ground structure, we must fully understand the relevant laws of earthquakes, and choose to carry out the project during the inactive period of the earthquake as much as possible; The constructors provide enough time to maximize the advantages of the shock absorption and isolation technology and improve the stability of the bridge structure. At the same time, relevant technical personnel must check the shock absorption and isolation equipment to reduce the adverse effects of the bridge structure.

[0004] Through the above analysis, the existing problems and defects of the existing technology are: the rigidity of the bridge in the prior art is not enough, and dislocation will occur after long-term use, which will affect the service life of the bridge
