Abstract

The invention discloses a concrete central protection fence, and relates to the technical field of public facilities. The device comprises a base, stand columns and a guardrail, wherein the base is abase composed of concrete, the stand columns are arranged on the base at intervals; the guardrail comprises an upper cross rod, a lower cross rod and a vertical rod; the two ends of the upper cross rod are fixed at the upper ends of two adjacent stand columns, and the two ends of the lower cross rod are fixed at the lower ends of the two adjacent stand columns, the vertical rod is arranged betweenthe upper cross rod and the lower cross rod, one end of the vertical rod is fixed on the upper cross rod, and the other end of the vertical rod is fixed on the lower transverse rod. The concrete central protection fence has the advantages that the structure is simple, the anti-collision effect is good, the appearance is delicate and attractive.

Description

technical field [0001] The invention relates to the technical field of public facilities, and more specifically relates to a guardrail, especially a concrete central guardrail. Background technique [0002] On the main road sections of urban roads, it is common for pedestrians to cross the street at will, vehicles to turn around at will, and to borrow the target lane to drive. Separate lanes to motor vehicles, which can ensure safe, smooth and orderly road traffic, and can also play a certain protective role. [0003] Most of the existing isolation guardrails are metal railings, and the foundation is made of cast iron base. The columns of adjacent isolation nets are inserted into the base, and the columns of adjacent units are fixed and combined with connectors to resist the impact of wind and personnel overturning. , the guardrail with the above structure is easy to fall over when encountering strong wind, people overturning or vehicle collision, and a chain reaction will ...
