Abstract

The invention discloses a road and bridge safety anti-collision guardrail which comprises a plurality of anti-collision guardrail bodies. Every two adjacent anti-collision guardrail bodies are connected through first limiting lock plates. Each anti-collision guardrail body comprises a supporting base. A plurality of limiting guide columns are fixed to the supporting base in the length direction; first limiting support plates are arranged among the plurality of limiting guide columns; second limiting support plates are arranged above the first limiting support plates among the plurality of limiting guide columns; nuts are in threaded connection on the limiting guide columns under the first limiting support plates; anti-collision carrier rollers are arranged between the first limiting supporting plates and the second limiting supporting plates; and an upper end connecting shaft is fixed at the upper end of each anti-collision carrier roller. The road and bridge safety anti-collision guardrail is convenient to mount and dismount, high in universality and stable.

Description

technical field [0001] The invention belongs to the technical field of roads and bridges, in particular to a safety anti-collision guardrail for roads and bridges. Background technique [0002] Road bridges are generally composed of roadbeds, road surfaces, bridges, tunnel engineering, and traffic engineering facilities. Both sides of road bridges will be equipped with guardrails to protect vehicles and drivers, and prevent vehicles from rushing out of the road or Bridges therefore require road bridge safety crash barriers. [0003] But the present road and bridge safety anti-collision barrier still has the problems of inconvenient installation and disassembly, poor versatility and instability. [0004] Therefore need to design a kind of installation and dismounting convenience, strong versatility, stable road and bridge safety anti-collision guardrail is very necessary. Contents of the invention [0005] The object of the present invention is to provide a road and bridg...
