Problems solved by technology

[0006] The technical problem to be solved by the present invention is that, in view of the defects that the steel guardrails in the prior art are easy to corrode, have high hardness, and poor absorption of impact energy; High defects; and steel-plastic composite guardrails have complex production process and relatively poor impact energy absorption, providing a hollow guardrail that is corrosion-resistant, reduces maintenance difficulty, and can absorb impact energy well to reduce damage to vehicles and personnel

Embodiment 1

[0076] 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, and eight first rib plates 200 are arranged in parallel longitudinally along the beam plate 100, wherein Two are set 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. The width of the first rib 200, that is, the distance between the bottom end and the top end of the first rib 200, can be the same or different. , and the eight first ribs 200 are symmetrical with respect to the longitudinal center axis of the beam slab 100. In this embodiment, first ribs 200 of different widths are used. Among the four first ribs 200 on one side of the central axis of the beam slab 100 , the two first ribs 200 in the middle are wider than the width of the first ribs 200 on both sides. T...

Embodiment 2

[0078] Embodiment 2, as figure 2 The shown guardrail board is an improvement made on the basis of Embodiment 1, wherein the beam board 100 is a special-shaped board obtained by bending a flat board, and two square ribs are formed along the longitudinal direction, among which there are four first rib boards 200 Located on the edge of the rib and forming an integral structure with the rib, two are located on the edge of the beam plate 100 . Since the first rib 200 is made of a thermoplastic composite board, the reinforcing frame in the first rib 200 on the rib of the beam plate 100 extends toward the side wall of the rib, and the rest of the structure is the same as that of Embodiment 1 and will not be repeated here.

Embodiment 3

[0079] Embodiment 3, as image 3 The shown guardrail is an improvement on the basis of Embodiment 1. The beam plate 100 remains unchanged, and six first rib plates 200 are provided. The six first rib plates 200 are symmetrical about the central axis of the beam plate 100, and each side of the central axis Set three first ribs 200, the first ribs 200 on the same side are all inclined to the edge of the beam plate 100, the inclination angle is the same or different, the inclination angle of the first rib 200 is 70-85°, the second rib 300 In this embodiment, part adopts a two-layer structure, and the other part adopts a single-layer structure. That is, among the six first ribs 200, two layers of second ribs 300 are set between the second and third second ribs 300 from the edge, and between the fourth and fifth second ribs 300. A layer of second ribs 300 is arranged between the first ribs 200 . The second rib 300 disposed at the top of the first rib 200 extends toward the direct...

Abstract

A hollow guiderail panel comprising a beam panel (100) and first rib panels (200). The multiple first rib panels (200) are arranged on a panel face of the beam panel (100) and are integrally arranged with the beam panel (100). The beam panel (100) and the first rib panels (200) extend along the lengthwise direction of the guiderail panel. Every two adjacent first rib panels (200) are provided therebetween with a second rib panel (300). The second rib panel (300) extends along the lengthwise direction of the guiderail panel and encloses a hollow cavity in conjunction with the first rib panels (200) and the beam panel (100). The beam panel (100) and the second rib panel (300) are thermoplastic composite panels or thermoplastic material panels. The first rib panels (200) are thermoplastic composite panels. Each thermoplastic composite panel comprises a reinforced skeleton (4). The reinforced skeleton (4) is covered thereout with a thermoplastic material layer. The hollow guiderail panel is corrosion-resistant, has a simplified manufacturing process, and ensures vehicle and personnel safety by adsorbing impact energies.

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 hollow 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, cau...
