Embodiment Construction

[0038] The present invention will be described in detail below in conjunction with the drawings.

[0039] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0040] Such as Figure 1~3 As shown, a safe and easy-to-maintain steel guardrail includes a column 1, a column decorative cover 2, a mesh 3; the body of the column 1 is a cylindrical steel pipe A11, on which a column flange 12 and a connector 13 are welded, so The column flange 12 on the column 1 is set at a distance of 15-25 cm from the bottom end of the column 1, and the part below the column flange is inserted below the ground, which can effectively resist impact, and does not require concrete...

Abstract

The invention relates to the field of traffic safety fences, and particularly discloses a safe steel fence easy to maintain. The safe steel fence easy to maintain comprises upright posts, upright post decorative covers, mesh pieces and upright post pre-buried pieces; each upright post main body is a cylindrical steel tube A; an upright post flange and a connector are welded on each cylindrical steel tube A; the upright post decorative covers can be nested in the upright posts; the mesh pieces are arranged between the two upright posts and are connected with the upright posts through the connectors on the upright posts; each upright post pre-buried piece is formed by welding a steel tube B, a guide steel plate and an internally threaded steel tube; the bottom end of each upright post pre-buried piece is conical; the internally threaded steel tube is welded with the side wall of the steel tube B in parallel; the guide steel plate is welded with the outer side of the internally threaded steel tube or is arranged adjacent to the internally threaded steel tube. The safe steel fence easy to maintain is stable in structure, high in safety performance, not easy to damage and low in production cost, and is low in maintenance cost and convenient to replace after being damaged.

Description

Technical field [0001] The invention relates to the field of traffic safety guardrails, and specifically discloses a safe and easy-to-maintain steel guardrail. Background technique [0002] At present, road guardrails on the market can be divided into two categories according to whether they have a base or not. The first type is a base type, and the second type is a baseless type (ie, embedded type, hereinafter referred to as embedded type). Among them, the first type has a base type and can be subdivided into two types: [0003] One type is a pluggable base (according to the material of the base, it can be divided into resin SMC base, iron-filled concrete base, cast iron base, etc., not detailed here); the other is flange welded base. In order to facilitate the following discussion, we divide the above three types of guardrails into three categories: the first type is pluggable base guardrail, the second type is flanged base guardrail, and the third type is embedded guardrail.
