Benefits of technology

This patented technology reduces damage caused by collisions between vehicles during accidents or crashes over roads without causing any significant problems for drivers' safety. It also extends its lifespan even if only partially used up because it can be easily installed onto existing traffic lights that were previously designed. Additionally, this design prevents excess pressure from being applied directly upon vulnerable areas such as bumpers, which could cause them to break down quickly.

Problems solved by technology

The technical problem addressed in this patented text relates to improving safety for guards used along roads during crashes caused by cars that collide into them without causing damage themselves. Current methods involve adding extra padding around certain parts of the guide rail itself but these can also cause harm when they hit another part too close together. This results in wasted material and increased costs associated with replacing worn out components overtime.

Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0018] Such as figure 1 and figure 2 As shown, the present invention provides a polyurethane guardrail, comprising:

[0019] Pillar 1, a metal guardrail matrix 2 is fixed between two adjacent pillars, and the metal guardrail matrix mainly prevents the vehicle from rushing to other lanes when it hits the guardrail. The pillars are fixed on the ground through the fixtures, the distance between the two pillars is 10-15 meters, and the two ends of the metal guardrail matrix are welded on the two pillars.

[0020] A plurality of polyurethane protective sheets 3 are dispersedly arranged on the metal guardrail base, and two adjacent polyurethane protective sheets are arranged in parallel, which can be arranged horizontally or vertically. The polyurethane buffer sheet can be used whe

Abstract

The invention relates to the field of guardrails, in particular to a polyurethane guardrail which comprises supporting columns and multiple polyurethane protecting pieces. A metal guardrail substrate is fixed between each two supporting columns, the polyurethane protecting pieces are arranged on the metal guardrail substrates in a scattered manner, each polyurethane protecting piece is fixed to the corresponding metal guardrail substrate through multiple first polyurethane buffering bodies integrally arranged on one surface of the corresponding polyurethane protecting piece, an opening portion is arranged on one side portion of each polyurethane protecting piece and extends towards the inside of the corresponding polyurethane protecting piece to form a containing space of 1/3 away from the other side portion of the corresponding polyurethane protecting piece, a spring is fixed on the other side portion of each polyurethane protecting piece, a second polyurethane buffering body is connected on each spring, and each spring and the corresponding second polyurethane buffering body are disposed in the corresponding containing space. The polyurethane guardrail has the advantages that damping performance of the polyurethane guardrail is improved, and a damping function of the polyurethane guardrail is guaranteed while number of the polyurethane protecting pieces is reduced.
