Problems solved by technology

Its disadvantages are: the guardrail has poor elasticity and low rebound force. Occasionally, when a car collides with the guardrail, the guardrail is deformed, or the car rushes out of the guardrail, causing injury accidents; the galvanized layer is easy to oxidize, blacken, or even peel off. , and affect the landscape on both sides of the road; the guardrail also needs to be equipped with luminous warning devices

Embodiment Construction

[0011] choose light Steel or Shaped plastic steel is used as a column (1), and a bolt hole for installing a guard plate (3) is established on the top of one wing; After modified by additives such as colored mineral pigments, it is extruded into a cross-section of Glyph sheet, when extruded, in A continuous luminous powder line (4) is injected into the middle of the top of the glyph, and after cooling and setting, the steel bar and plastic are solidified together; the elastic gasket (2) is an elastic rubber gasket; the guard plate (3) and the elastic gasket (2) Bolt holes are correspondingly established on the top, and the guard plate (3) and elastic gasket (2) are fixed on the top of the column (1) with bolts (5). The elastic sleeve (8) adopts elastic rubber, and the bottom of the column (1) is buried in the soil or concrete after the elastic sleeve (8) is set close to the surface.

Abstract

The invention relates to guard bar of high-speed road, belonging to the construction of fence. The invention comprises post and guard board, which is characterized in that: bolt holes for installing guard board are mounted in the upper part of post; the guard board which using screw steel bar as reinforced rib, is improved by the agent which containing project plastic as main material mixed with colorful mineral paint, to be molded and injected one continuous noctiluent line in the middle of top; guard board and resilient plate are fixed on the top of post with their bolt holes; the low part of post which is near the surface of ground are put into a resilient cylinder to embedded into soil or concrete. The advantages of this invention include better resilience of guard bar, big rebound, and reducing the harm and death rate when the car are shocked.

Description

technical field [0001] The invention belongs to the construction of fences, in particular to guardrails for highways. Background technique [0002] With social progress and economic and trade prosperity, expressway construction has developed rapidly, and expressways have spread throughout cities and villages. For the safety of driving, roadside construction facilities and personnel, highway guardrails are particularly important, and the performance requirements for guardrails are getting higher and higher. As far as the inventor knows, the inner and outer guardrails of the expressway in the prior art are steel corrugated plates installed on the columns; the steel corrugated plates are cold-rolled galvanized plates. Its disadvantages are: the guardrail has poor elasticity and low rebound force. Occasionally, when a car collides with the guardrail, the guardrail is deformed, or the car rushes out of the guardrail, causing injury accidents; the galvanized layer is easy to oxid...
