Problems solved by technology

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

Embodiment 1

[0081] Embodiment 1, as figure 1In the shown corrugated guardrail board, the base plate 10 is a flat thermoplastic composite plate, and a plurality of connecting holes 50 are spaced apart on the central axis of the base plate 10, and bolts 11 are installed in the connecting holes 50 to connect the anti-blocking block 100 and the column. 200 fixedly connected together. Corrugated plates 20 are respectively extended at both ends of the substrate 10 in the lateral direction, the substrate 10 and the corrugated plate 20 are integrally structured, and the corrugated plates 20 protrude toward the same side of the substrate 10 and exceed the substrate 10. The base plate 10 smoothly transitions to the corrugated plate 20; both the base plate 10 and the corrugated plate 20 extend in the length direction of the guardrail, the base plate 10 and the corrugated plate 20 are thermoplastic composite plates, and the thermoplastic composite plate includes a reinforced skeleton 4 , the reinfor...

Embodiment 2

[0087] Embodiment 2, as figure 2 The shown guardrail is an improvement made on the basis of Embodiment 1, that is, the top plate 22 of the corrugated plate 20 is changed from an outwardly protruding arch to a straight shape, and the thickness of the buffer layer in the thermoplastic material layer in the top plate 22 is that of other positions. 1.5 to 2 times. In this embodiment, no flange plate 30 is provided, and the thermoplastic material layer at the edge of the outer wall plate 21 is semi-cylindrical. The rest of the structure is the same as that of Embodiment 1 and will not be repeated here.

Embodiment 3

[0088] Embodiment 3, as image 3 The guardrail shown is an improvement on the basis of Embodiment 2, the base plate 10 remains unchanged, and the reinforcing skeleton 4 in the top plate 22 of the corrugated plate 20 is M-shaped or V-shaped. The depression is filled up by the buffer layer of the thermoplastic material layer, and the thickness of the buffer layer here is 1.5 to 2 times that of other positions. Such a structure of the top plate 22 greatly increases the thickness of the thermoplastic material layer on the outside of the reinforcement framework 4 at the top plate 22 , which strengthens the flexibility and cushioning capacity of the top plate 22 . The rest of the structure is the same as that of Embodiment 2 and will not be repeated here.

Abstract

The invention discloses a corrugated guardrail plate comprising a baseplate fixedly connected with an obstruction block or a standing column, wherein corrugated plates respectively extend out of two sides of the baseplate; the baseplate is integrated with the corrugated plates; the corrugated plates protrude to the same side of the plate face of the baseplate and exceed the plate face of the baseplate; a smooth transition is adopted between the baseplate and each corrugated plate; both the baseplate and the corrugated plates extend in the length direction of the guardrail plate and 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 an all-plastic guardrail plate, and complex manufacturing technology and worse collision energy absorption of a plastic-steel guardrail plate, the invention provides the corrugated guardrail plate, which has the advantages of corrosion resistance and appropriately matched rigidity and flexibility and can reduce harm to a vehicle and personnel to the greatest extent.

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 corrugated 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,...
