Viaduct anti-collision energy dissipation fence

Abstract

A viaduct anti-collision energy dissipation fence comprises a viaduct surface, built-in steel plates, threaded steel bars, reserved threaded holes, elastic anti-collision plates A, elastic anti-collision plates B, steel bar grooves, damping pieces, steel sheets, energy dissipation springs, fixing ribs, rectangular connecting grooves, rubber cushion layers, U-shaped fence shells, tapping screws, high-strength bolts and reserved bolt holes. The fence is arranged on two sides of a viaduct to substitute a reinforced concrete structure, elastic material is used, a rubber layer, an energy dissipation spring and two layers of elastic plates are internally arranged for energy dissipation and collision prevention; the whole structure is fixed on the reinforcing steel bars, the reinforcing steel bars are fixed with the built-in steel plate of the bridge floor, the structure connection is reliable, the safety performance is high, and the whole structure is displaced for a certain distance under the action of the energy consumption springs and the rubber to buffer the damage to vehicles and human bodies caused by collision. The fence is convenient to connect, safe, reliable and suitable for the technical field of bridges, especially for integrated development of bridge fences.

Description

technical field [0001] The invention relates to a fence, in particular to an anti-collision energy-consuming fence for viaducts. Background technique [0002] Guardrails can be seen everywhere, playing the role of protection and isolation. Viaducts are widely used in cities because of their convenience, and the safety measures on viaducts are the focus of our attention at all times. Maintenance facilities for vehicles on viaducts in case of collisions It is the most important thing. Although the traditional steel-concrete fence structure can ensure that the vehicle will not fall on the bridge and cause a greater incident under the bridge, the loss of the vehicle is more serious, and the larger collision will bring people more serious injuries. Life is threatened, so researching a kind of anti-seismic and energy-consuming fence device can further solve this problem. Contents of the invention [0003] The purpose of the present invention is to provide a viaduct anti-collisi...
