Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a construction guardrail which is easy to adjust. Background Art

[0002] Construction guardrail is made of iron pipe, which is processed by seamless iron pipe bending, welding, grinding and polishing, high pressure painting, film pasting and other processes. It is generally widely used for isolation and warning of construction sites. Construction guardrail is generally used in ordinary roads, highways, and all levels of highway intersections, toll stations, bridges, parking lots, stations, docks, dangerous areas and road construction areas.

[0003] According to the Chinese patent publication number CN 112376998 A, the present invention provides a guardrail support column and a building construction guardrail. The guardrail support column includes: a base; a column, which is arranged on the base to support the fence; two support rods, whose bottom ends are respectively arranged on both sides of the column and are rotatably connected to the base; two pressure rods, which are arranged one by one with the support rods, and the first end of each pressure rod is connected to the corresponding support rod through a first buffer mechanism, and the second end of each pressure rod is connected to the column through a second buffer mechanism to buffer external force impact, so as to improve the anti-collision ability of the fence. The present invention provides lateral support force to the column through support rods and pressure rods to prevent the guardrail from tipping over; the first buffer mechanism and the second buffer mechanism buffer external force impact, thereby improving the anti-collision ability and protection ability of the guardrail, and further improving the stability and protection effect of the guardrail.

[0004] but:

[0005] Construction guardrail is one of the most important things on the construction site. It can be said that it is related to people's safety.
