Shock absorption device for bridge construction

Abstract

The invention discloses a shock absorption device for bridge construction. The shock absorption device comprises a bottom plate; the two sides of the top of the bottom plate are fixedly connected with piston cylinders; the opposite sides of the two piston cylinders are fixedly connected with box bodies; the box bodies communicate with the corresponding piston cylinders through communicating pipes; the interiors of the box bodies are movably connected with sliding plates; one side, far from the corresponding piston cylinder, of each sliding plate is fixedly connected with one end of a sliding rod; one end, far from the corresponding sliding plate, of each sliding rod penetrates through the corresponding box body and extends to the exterior of the corresponding box body; the parts of the bottoms, located at the exteriors of the box bodies, of the sliding rods are slidingly connected with the top of the bottom plate; the interiors of the piston cylinders are movably connected with pistons. Through buffering solutions in the piston cylinders and the box bodies, and by matching with a spring between two fixing blocks and employing repulsive force between a first magnet block and a second magnet block, vibration force of the top plate, generated in the bridge construction process is buffered effectively, and the shock absorption device is high in shock absorption effect, applicability and reliability and is convenient and practical.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a damping device for bridge construction. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology or meet other transportation needs to make traffic more convenient. A bridge is generally composed of a superstructure, a substructure, a support and ancillary structures. The superstructure is also called a bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers and foundations; Or the force transmission device installed at the supporting place of the bridge abutment; the auxiliary structures refer to the bridge head board, conical slope protection, bank prote...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of damping device for bridge construction, to solve the shock absorption mode of the current damping device for bridge construction proposed in the above-mentioned background technology all only by adding rubber shock absorbing pads at its bottom, such damping The shock absorption effect of the shock method is poor, and only part of the vibration force can be eliminated, which has poor applicability and low reliability.
