Road isolation fence with built-in coordinated energy consumption combined structure

Abstract

The invention provides a road isolation fence with a built-in coordinated energy consumption combined structure, which belongs to the field of highway traffic facilities. The road isolation fence witha built-in coordinated energy consumption combined structure comprises an anti-collision pad, an energy consumption connecting plate, an energy consumption base plate, a damping and buffering material, a connecting piece, back plates, a coordinated energy consumption combined structure, a connecting plate, connecting cross beams, an energy consumption mild steel plate A, an energy consumption mild steel plate B, a high-strength fixing hinge, a common fixing hinge, a vertical connecting and fixing pile and a hinge coordinated connecting elastic rod. The highway isolation fence with the built-in coordinated energy consumption combined structure is provided with a plurality of connecting cross beams, the left and right sides of the connecting cross beam are fixed with the vertical connectingand fixing pile; and the front side and the rear side of the connecting cross beam are symmetrically provided with the back plates. The road isolation fence with a built-in coordinated energy consumption combined structure has the advantages that industrial disassembly is convenient, the arranged anti-collision pad can play a role in buffering and protecting, the impact force can be greatly buffered, the overall structure is good in coordinated and connection performance, the cost is low, manufacturing is easy, and the industrialization process can be promoted.

Description

technical field [0001] The invention belongs to the field of road traffic facilities, in particular to a road separation fence with a built-in coordinated energy consumption combined structure. Background technique [0002] With the development of the national economy, a large number of roads and expressways have been built or are under construction. At present, the guards on both sides of the expressway and the road are made up of columns and a guard plate positioned on its top, and the guard plate is made of steel plates, both of which are rigid materials and are rigidly connected. When the car loses control and hits the protective plate, the protective device can prevent the car from turning into the waterproof ditch on both sides of the expressway or rushing into the opposite lane to crash. But practice has proved that the protective plate of the above structure has no cushioning function. Under the high-speed and powerful impact of an out-of-control car, the protective...

Problems solved by technology

At present, the existing guardrails on the market do not have the function of cushioning and shock absorption when they are in use. When a car hits the guardrail, it can only rely on the deformation of the guardrail to damage the energy absorption, and the deformation and energy absorption capabilities are limited.

And the guardrail board is easy to break under the impact of the car, causing the guardrail to be unable to use normally, and it is also easy to cause secondary damage to the safety of the vehicle and the crew. In summary, how to solve the deformation ability and energy absorption of the existing highway guardrail The problem of limited ability has become a problem that those skilled in the art need to solve
