Bridge position-limiting energy-dissipating shock-absorbing and isolating bearing and manufacturing method thereof

Abstract

The invention discloses a bridge position-limiting energy-consuming shock-absorbing and isolating bearing and a manufacturing method thereof, belonging to the technical field of bridge bearings. The support includes an upper support plate, a support base basin and a shock isolation module, the upper support plate is located on the support base basin, and the surrounding areas of the upper support plate are composed of external steel plates, high damping rubber blocks, and inner connecting steel plates. shock isolation module. The high damping rubber block is located between the vertical plate in the external steel plate and the inner connecting steel plate. A limit stop is arranged around the bottom plate of the support base to limit the horizontal direction of the external steel plate, and the limit stop is close to the vertical plate. On the inner side, when the limit bolts are sheared due to the external force, the steel plate is added to limit the relative displacement of the pier beam, and the high damping rubber block dissipates energy through shearing and tension-compression deformation to play a shock-absorbing function and a certain self-resetting ability. The biggest advantage of the invention is that the limiting function of the pier beam is integrated into the traditional spherical bearing or basin bearing, which reduces the difficulty of design and construction and the economic cost of post-earthquake repair.

Description

technical field [0001] The invention relates to the technical field of bridge manufacture, in particular to a bridge position-limiting energy-dissipating type shock-absorbing and isolating support and a manufacturing method thereof. Background technique [0002] Excessive relative deformation of pier beams or even falling beams are important manifestations of bridge earthquake disasters. For this reason, people have developed a variety of technologies to limit the relative deformation of pier beams under earthquake action. These technologies are generally independent of the support. By setting stoppers, steel plates, cables and other devices between the bridge pier and the main girder, it will make the space layout, reinforcement and construction formwork of the main girder and bridge pier more complicated. The present invention proposes a new space-limited shock-absorbing and isolating bearing on the basis of traditional bearings such as spherical bearings and pot bearings....
