Abstract

The invention provides an anti-collision guardrail of single-beam steel, comprising a single-beam guardrail plate, an assembling plate, a reinforcing steel pipe, an assembling bolt, a protecting block and an upright post. The cross section of the single-beam guardrail plate is in the shape of arc; the upper edge and the lower edge of the guardrail plate are inward and spirally rolled towards the protruding direction of the guardrail plate, so as to form two energy storage rings; through the assembling bolt, the single-beam guardrail plate and the reinforcing steel pipe are connected together, and the assembling plate is arranged between the single-beam guardrail plate and the reinforcing steel pipe. Through the protecting block, the assembled guardrail plate is connected with the guardrail upright post together. When collision happens, the energy storage rings at upper and lower sides of the guardrail plate can be opened; compared with the other anti-collision guardrails, the anti-collision guardrail has better buffer property. Besides, the inner part of the protecting block is hollow; when collision happens, a secondary buffer is carried out, thereby greatly reducing the collision destructive effect.

Description

technical field [0001] The invention relates to the field of anti-collision barrier devices, in particular to a single-beam steel anti-collision barrier device. Background technique [0002] With the rapid development of my country's road construction and transportation industry, traffic safety is facing a severe situation. As a safety facility, crash barriers play an important role in protecting the traffic safety of roads and bridges. Generally, crash barriers mainly include three types: rigid guardrails, semi-rigid guardrails and flexible guardrails; among them, rigid guardrails are mainly concrete guardrails, which have excessive rigidity, so the ability to buffer and absorb vehicle kinetic energy is weak; When the center of gravity of the vehicle is relatively high, the vehicle tends to turn over the concrete guardrail after hitting the concrete guardrail; when the center of gravity of the vehicle is relatively low, the vehicle tends to turn laterally after hitting the...
