Multidirectional distributed bridge damping structure with positioning structure

Abstract

The invention discloses a multidirectional distributed bridge shock absorption structure with a positioning structure, and relates to the technical field of bridge shock absorption, in particular to the multidirectional distributed bridge shock absorption structure with the positioning structure, which comprises a positioning base, and the left side and the right side of the positioning base are respectively provided with an outer barrier separation buffer mechanism; a bottom separation buffering mechanism is installed at the bottom in the positioning base, a front beam supporting column is installed above the bottom separation buffering mechanism, a limiting shaft plate is arranged in the front beam supporting column, and a limiting spring is installed above the limiting shaft plate. Themultidirectional distributed bridge shock absorption structure with the positioning structure is provided with the limiting springs and the energy consumption dampers, preliminary buffering treatmentcan be effectively provided for the limiting shaft plates through the limiting springs, and front beam supporting columns can be effectively assisted through symmetrical distribution of the energy consumption dampers; and the collision strength borne by the front beam supporting column can be effectively consumed, and therefore effective buffering treatment can be provided for the front beam supporting column.

Description

technical field [0001] The invention relates to the technical field of bridge damping, in particular to a multidirectional decentralized bridge damping structure with a positioning structure. 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 cross mountains, poor geology, or meet other traffic needs to make traffic more convenient. Bridges are generally composed of superstructure, substructure, supports and subsidiary structures. The superstructure is also called bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers and foundations; the supports are bridge The force transmission device installed at the supporting place between the span structure and the bridge pier or bridge abutment; the auxili...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a multi-directional decentralized bridge damping structure with a positioning structure, which solves the problem that the existing bridge damping structure proposed in the above-mentioned background technology is in use when the bridge is collided. The buffer position of the bridge is relatively single, and the bridge is prone to deflection, which cannot provide effective decentralized buffering for the bridge.
