Temporary traffic guardrail

Abstract

The invention discloses a temporary traffic guardrail. The temporary traffic guardrail comprises a square frame, supporting legs arranged below the square frame, and a plurality of railings verticallyarranged in the square frame; a plurality of sub-plates are arranged on the railings; the sub-plates are arrayed on the railings to form a continuous zigzag shape; the included angle between the sub-plates arrayed in the zigzag shape is 60-90 degrees; air exhaust channels for air circulation are reserved between the sub-plates; and air exhaust hole ducts for air circulation are arranged at the side edges of the connecting positions of the sub-plates and the railings from top to bottom. According to the temporary traffic guardrail, required warning characters, marks and advertisements can be pasted or painted on the sub-plates, and the sub-plates can be spliced into a larger and more complete three-dimensional surface to ensure the warning and publicity effects; and depending on the air exhaust channels, wind can flow from the air exhaust channels at the included angle to the rear when the wind is guided to the included angle along the plate surface, so that the wind force borne by thesub-plates is reduced, the temporary traffic guardrail is not prone to being blown down, and the stability and safety are improved.

Description

technical field [0001] The invention relates to the field of guardrails, in particular to a temporary traffic guardrail. Background technique [0002] Traffic guardrails play an important role in urban traffic. They can separate lanes, or block roads, and warn people or vehicles; they can better regulate traffic order. [0003] Among them, the temporary traffic guardrail is set as a single-piece structure, which is transported and arranged on the road to block traffic when needed; the temporary traffic guardrail of the single-piece structure will be provided with a flat plate-shaped plate structure on the surface of the guardrail for setting warning text and signs. Or advertising, etc.; but because the single-piece structure of the temporary traffic guardrail has no peripheral structure for auxiliary fixing, after the flat board is installed, it will bear a large wind force when it is blown by the wind, and the overall temporary traffic guardrail is easier when the wind is s...

Problems solved by technology

[0003] Among them, the temporary traffic guardrail is set as a single-piece structure, which is transported and arranged on the road to block traffic when needed; the temporary traffic guardrail of the single-piece structure will be provided with a flat plate-shaped plate structure on the surface of the guardrail for setting warning text and signs. Or advertising, etc.; but because the single-piece structure of the temporary traffic guardrail has no peripheral structure for auxiliary fixing, after the flat board is installed, it will bear a large wind force when it is blown by the wind, and the overall temporary traffic guardrail is easier when the wind is strong. If it is blown over, it will affect the normal use and may injure pedestrians; therefore, how to resist the wind well and ensure the stable use of temporary traffic barriers with plate signs is a problem that needs to be solved urgently
