Embodiment 1

[0077] Embodiment 1, as figure 1 In the shown guardrail board, the beam plate 100 is a flat thermoplastic material plate, and a plurality of installation holes 500 are spaced apart on the central axis of the beam plate 100. Eight rib plates 200 are arranged in parallel longitudinally along the beam plate 100, two of which are It is arranged on the edges of both sides of the beam slab 100, and the others are evenly distributed in the direction of the center of the beam slab 100, and the eight ribs 200 are symmetrical about the longitudinal central axis of the beam slab 100, and connecting ribs 300 are respectively arranged between adjacent ribs 200 , the connecting rib 300 is a plate structure, and connects the adjacent ribs 200 from the beginning to the end. The connecting ribs 300 are perpendicular or substantially perpendicular to the ribs 200 , and the positions of the connecting ribs 300 are the same, they are all close to the beam slab 100 , about one-third of the ribs 20...

Embodiment 2

[0078] Embodiment 2, as figure 2 The guardrail shown is an improvement made on the basis of Embodiment 1, wherein the beam plate 100 is a special-shaped plate obtained by bending a flat plate, and two square ribs are formed along the longitudinal direction, among which there are four ribs 200 located on the convex side. The edges of the ribs, two of which are located at the edge of the beam slab 100. A flange is provided on the top of the rib 200 . The flanges extend to both sides of the rib 200 and are parallel to the beam 100 . The cross-section of the rib 200 forms a T-shaped structure. Both sides of the reinforcing frame 4 are provided with flanges that are folded to both sides respectively, the flanges of the reinforcing frame 4 at the top of the rib plate 200 are respectively arranged on both sides of the flange, and the flanges of the reinforcing frame 4 at the bottom of the rib plate 200 Fold into the beam panels 100 on both sides respectively. The rest of the struc...

Embodiment 3

[0079] Embodiment 3, as image 3 The shown guardrail is an improvement on the basis of Example 1, the beam 100 remains unchanged, and the ribs 200 are respectively inclined to the two sides of the beam 100, and the inclination angle is 70-85°. Among them, the ribs 200 The section is wedge-shaped, and the thickness of the top of the wedge is greater than that of the bottom. The thickened and raised top is conducive to buffering and absorbing energy; adjusting the length of the flange of the reinforced skeleton, as well as the number and position of the connecting ribs 300 can adjust the flexibility of the guardrail. Good for cushioning under different protection levels. The rest of the structure is the same as that of Embodiment 1 and will not be repeated here.

Abstract

The invention discloses a ribbed guardrail plate comprising a beam plate, wherein a plurality of rib plates integrated with the beam plate are arranged on the plate face of the beam plate; the beam plate and the rib plates extend in the length direction of the guardrail plate; the beam plate is a thermoplastic composite plate or a thermoplastic material plate; the rib plates are thermoplastic composite plates; and each thermoplastic composite plate comprises a reinforcing frame wrapped in a thermoplastic material layer. Aiming to overcome the defects of high probability of corrosion, high rigidity and poor collision energy absorption of a steel guardrail plate, small elastic modulus, large size and high cost of the all-plastic material of an all-plastic guardrail plate, and complex manufacturing technology and worse collision energy absorption of a plastic-steel guardrail plate, the invention provides the ribbed guardrail plate, which has the advantages of corrosion resistance and lower maintenance difficulty and can excellently absorb collision energy to reduce harm to a vehicle and personnel.

Description

technical field [0001] The invention belongs to the technical field of road traffic safety facilities, and relates to a guardrail, in particular to a rib-shaped guardrail. Background technique [0002] High-speed traffic enclosures and large-scale site enclosures often require the use of protective panels or guardrails. They are used in a wide range of fields, involving transportation, agriculture, entertainment, industry, construction and other industries. For example, guardrails are often used in livestock breeding in agriculture, large residential areas, Safety anti-collision facilities for highways, bridges, large industrial bases and large entertainment venues such as racetracks and racing tracks. [0003] Among them, the most important safety protection is traffic, especially highways, expressways and bridges, which all need guardrails. The main function of guardrails is to protect driving vehicles and prevent vehicles from rushing out of the road in case of accidents,...
