Problems solved by technology

With the accelerated development of economic globalization and regional economic integration, the span of the bridge is getting larger and larger. With the increase of the span, the construction environment faced by the bridge is also more complicated. In the field of bridge construction, the shock absorber is an important part of the service life of the bridge. The shock absorber can re

Abstract

The invention discloses a novel damping device for a bridge. The damping device comprises a square base, a plurality of fixed inserting columns are fixed at the bottom end of the square base, concavespherical sliding grooves are formed in the center of the top surface of the square base in a fixing mode, and through holes are respectively formed in the four corners of the square base. The dampingdevice has a simple structure, when a top plate is under pressure, a bridge pier is not directly subjected to force transmitted from bridge pavement, the force transmitted from the bridge pavement istransmitted to the bridge pier after being buffered by springs and first springs so that the springs and the first springs can play a role of protecting the bridge pier; and when the springs and thefirst springs cannot bear the force acting on the top plate, a vertical buffering device can play a supporting role between the square base and the top plate, and rubber pads inside the vertical buffering device also have a good buffering and damping effect. According to the arrangement of convex spherical sliding blocks and the concave spherical sliding grooves, when the bridge pavement shakes, the convex spherical sliding blocks rotate in the concave spherical sliding grooves, and thus the effects of buffering and damping are achieved.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a novel bridge damping device. Background technique [0002] A bridge refers to a building built for roads to cross natural or artificial obstacles. It is erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. A bridge generally consists of a superstructure, a substructure and ancillary structures. The superstructure mainly refers to the bridge span structure and support system; the substructure includes abutments, piers and foundations; , diversion engineering, etc. According to the structural system of bridges, there are four basic systems: girder bridge, arch bridge, rigid frame bridge, and suspension cable bearing (suspension bridge, cable-stayed bridge). With the accelerated development of economic globalization and regional economic integration, the span of the bridge is getting larger and larger. With the increase of the span, the construct...
