Problems solved by technology

[0003] However, due to the simple structure of the conventional guardrail, as shown in Figure 1, wherein the metal protective sheet 2 is engaged with the guardrail pillar 1, and there is no additional damping device, if a vehicle collides with the guardrail, it will be strongly impacted, resulting in serious personal injury
[0004] In addition, since the protective sheet of the conventional guardrail is made of metal, there is a problem that it will be corroded after long-term use in the external environment
However, installing reflectors creates an additional expense, which increases the cost

Embodiment Construction

[0023] The preferred embodiment of the present invention will be described in detail below with reference to Fig. 2 and Fig. 3 of the accompanying drawings.

[0024] As described above, the guard sheet, which is the main part of the guardrail, is made of resin and has the following structure for increasing strength (weakness of resin), and can be produced by molding.

[0025] That is, the guardrail includes pillars, a plurality of protective sheets engaged with the pillars, and connectors for connecting the protective sheets to each other, and each of the protective sheets 10 has a hollow plate-shaped base 100 . The base has an overall corrugated cross-section with one or more rearwardly protruding rear ridges 110 and one or more forwardly protruding frontal ridges 120 .

[0026] Each of the rear spines 100 includes a flat portion 111 . One or more first fastening holes 112 are formed on the flat portion 111 for fastening the protective sheet to the pillar 20 by screws. Each...

Abstract

The present invention relates to a resin guardrail including a post, a plurality of guard plates coupled to the post, and connection members for connecting the guard plates to one another. Each of the guard plates of the guardrail is manufactured through extrusion. The guard plate comprises a hollow base body that takes the shape of a wave in cross section to include a rear ridge protruding rearward and having a flat portion and a front ridge protruding forward. The flat portion of the rear ridge and the front ridge are formed with first and second fastening holes, respectively, and the base body has solid portions for reinforcing regions with the first and second fastening holes formed therein. The guard plate further comprises wavy ribs that are positioned within a hollow portion of the base body to connect upper and lower ends of the base body to each other and have the same sectional shape as the base body; and alternately arranged horizontal ribs for establishing connection between the wavy ribs and between the wavy ribs and inner surfaces of the base body.

Description

technical field [0001] The present invention relates to a resin guardrail, especially to a guardrail, wherein the guardrail is made of resin so as to fully possess the cross-section of the honeycomb structure so as to save raw materials, and the guardrail has higher strength than the metal guardrail, so The impact on the driver due to the collision of the vehicle with this guardrail can be suppressed to the greatest extent due to the properties of the material used or the elasticity due to the honeycomb structure, and by mixing in the manufacture of the protective sheet Fluorescent material is added so that it can emit light at night so that the driver's vision when driving at night is guaranteed. Background technique [0002] Guardrails are usually placed on the shoulders or in the middle of the road to indicate the boundaries of the road or to prevent vehicles from leaving the road. Such a guardrail is required to have sufficient strength to prevent the vehicle from runni...
