Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a recombined bamboo assembled guardrail. Background Art

[0002] It is necessary to set up a lot of isolation guardrails in the middle of the road, which mainly play the role of collision prevention and isolation. Compared with wood, bamboo has the advantages of being green, natural, high strength, good toughness, and short growth cycle. It is praised by structural engineers as "plant steel bars". Reconstructed bamboo is a new bamboo material that is reorganized and strengthened. The bamboo is processed into long strips of bamboo, bamboo fibers, or crushed into bamboo fiber bundles, which are then impregnated with glue after drying and then dried to the required moisture content. They are then laid in molds and thermally cured at high temperature and high pressure to form profiles.

[0003] Once a car collides with the existing guardrail, the instantaneous impulse generated is enough to cause the energy absorbing part to break, and the sharp end of the broken part will pose a fatal danger to the people in the car;

[0004] The existing patent (Announcement No.: CN208830222U) is a reconstructed bamboo buffer isolation guardrail for roads. This utility model adopts a plastic hinge with high toughness to connect the front and rear ends of two adjacent reconstructed bamboo horizontal bars in the upper through hole and the lower through hole. Therefore, no matter the isolation guardrail is hit from the front, hit at an angle or hit from the side, when the impact force is small, the plastic hinge with high toughness itself has tolerance and buffering effect on the impact force, thereby protecting the integrity of the guardrail and avoiding damage to the isolation guardrail and harm to vehicles and passengers.

[0005] In view of the above problems, existing patents have provided solutions, but in actual use, they are not convenient to install and use on curved roads. At the same time, they are not convenient to replace when damaged, and the length of the guardrail cannot be adjusted, so the applicability is poor.

[0006] Therefore, a reconstructed bamboo assembled guardrail is proposed. Summary of the invention
