A two-way function separation type shock absorption system

Abstract

The invention discloses a two-way function-separated shock absorbing system, which includes a support shock absorbing mechanism, a lateral shock absorbing mechanism, an intermediate connection shock absorbing mechanism and a bridge expansion joint shock absorbing mechanism. The support shock absorbing mechanism is used for beam body and For the connection between the bridge piers, the lateral damping mechanism is used to buffer the lateral force and the longitudinal force of the support, and one end of the intermediate connection damping mechanism is connected to the beam body, and the other end is connected to the bridge pier. The present invention is provided with a support damping mechanism, a lateral damping mechanism, an intermediate connection damping mechanism, and a bridge expansion joint damping mechanism, which can buffer the stressed state of the beam body in multiple directions, under vertical load, lateral load and longitudinal load. At the same time, a certain degree of sliding and rotation can be realized. When earthquakes, strong winds or other vibrations occur, the displacement of the present invention exceeds the working range in normal environments. The shock absorption system uses the characteristics of the damping material to provide a certain damping force. Through The hysteretic energy dissipation of the damping rubber material plays a shock-absorbing effect.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a two-way function separation type damping system. 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,...

AI Technical Summary

Problems solved by technology

In actual use, earthquakes, wind vibrations, and other equipment vibrations may cause the vibration of the building structure itself, which may lead to structural damage accumulation, abnormal operation of equipment, and adverse reactions such as human discomfort

[0005] The bridge damping bearings in the prior art usually adopt low-friction bearings, which are installed at the lower part of the beam body, and all of them are too much consideration of the longitudinal force shock absorption analysis. When the earthquake or other factors cause the bridge to shake, its force The direction of is uncertain, so there is a big defect in the bridge shock absorption of the prior art
