Problems solved by technology

[0003] The technical problems to be solved by the present invention are: the highway guardrail made of metal material is inconvenient to install and disassemble, difficult to repair and maintain, the surface needs to be galvanized to increase the engineering cost, and the manufacturing process is relatively complicated, and there is a shortage of metal materials in China. The disadvantage of high cost is to provide a highway guardrail

Embodiment Construction

[0009] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0010] figure 1 It is a schematic diagram of the structure of the present invention, which includes columns 1 and fences 2, the fences 2 are placed between the columns 1, and a reinforcing block 3 is arranged in the middle of the columns 1. The reinforcing block 3 plays the role of strengthening and fixing, so that the column 1 is more firm. The structure of the present invention meets the high-strength requirements of the highway guardrail, and the guardrail absorbs the impact energy strongly, that is, the anti-collision ability is high, and the damage of the vehicle and the casualties of the passengers are reduced. , The concave-convex fit welding connectio...

Abstract

The invention relates to the technical field of guardrails, and in particular relates to an expressway guardrail. The expressway guardrail comprises columns and a breast board, wherein the breast board is arranged between the columns; and reinforcing blocks are arranged in the middle of the columns. The structure of the expressway guardrail provided by the invention conforms to the requirement of high strength of the expressway guardrail; the guardrail has strong capability in absorbing collision energy, namely high anti-collision capability, and thus reduces damage of vehicles and injuries and deaths of passengers; the breast board and the columns are in concave-convex matching and welded connection, and bolt connection or welding is not required; and thus the expressway guardrail is convenient to assemble and disassemble and favorable for repairing and maintaining.

Description

technical field [0001] The invention relates to a guardrail, in particular to a highway guardrail. Background technique [0002] With the rapid development of my country's industrial and agricultural production, my country's transportation industry is developing rapidly, the number of highways is increasing day by day, and the need for highway guardrails is increasing. The original single molding process to manufacture guardrails is far from meeting the needs of my country's highway construction. , so it is imperative to develop and produce special equipment for highway guardrails. Its disadvantages are: Highway guardrail requires high strength to prevent vehicles from rushing out of the road, causing car crashes and fatal accidents, and secondly requires guardrail steel to be small to reduce vehicle damage and passenger casualties. The metal guardrails used cannot solve the contradiction between the two: the steel or aluminum alloy highway guardrails are strong in impact re...
