Abstract
Description
Technical Field
[0001] This utility model belongs to the field of traffic safety protection, and specifically relates to a guardrail structure with synthetic rubber anti-blocking blocks. Background Technology
[0002] As a crucial component of highway traffic safety facilities, guardrails play a vital role in ensuring driving safety, improving road capacity, and promoting economic development. Corrugated beam guardrails are a common type of guardrail on Chinese highways, categorized by their location as median barriers and roadside guardrails. Spacer blocks are the load-bearing components of corrugated beam guardrails, typically installed between the corrugated beams and posts. Traditional spacer blocks are often made of materials such as steel and wood, which are prone to deformation after impact and difficult to restore to their original state. Furthermore, traditional spacer blocks are exposed to the outdoor environment for extended periods, making them susceptible to erosion from sunlight, rain, and other natural factors, leading to material aging and performance degradation.
[0003] Based on the above, a guardrail structure with synthetic rubber anti-collision blocks is proposed. This structure uses synthetic rubber anti-collision blocks, which possess characteristics such as high density, high strength, high toughness, and high wear resistance. Furthermore, synthetic rubber has good elasticity, enabling it to act as a buffer during collisions. It deforms under external force and effectively absorbs and disperses collision energy, thereby reducing damage to the guardrail and vehicles during collisions, while also lowering the risk of injury to personnel. Synthetic rubber anti-collision blocks are typically designed in block shape, with a relatively simple structure, convenient installation, and easy maintenance and replacement, reducing maintenance costs. The anti-collision blocks are connected using specific methods. For example, when the synthetic rubber anti-collision block is a hollow structure, it opens from the bottom, with bolt holes provided on the anti-collision block and corrugated plate, and anchor bolts penetrate for connection. In a solid structure, the anchor bolts pass through the corrugated plate and are driven into the synthetic rubber anti-collision block to form a connection; the anchor bolts are self-tapping screws. Synthetic rubber materials generally have good anti-aging properties, maintaining the stability of their physical and chemical properties over a long period, resulting in a longer service life compared to traditional anti-collision block materials, reducing the frequency of maintenance and replacement. Utility Model Content
[0004] The purpose of this invention is to provide a guardrail structure with synthetic rubber anti-blocking blocks to solve the problems of traditional anti-blocking blocks having some obvious shortcomings in terms of material performance, maintenance and protective effect.
[0005] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows:
[0006] A guardrail structure with synthetic rubber anti-blocking blocks includes synthetic rubber anti-blocking blocks, posts, corrugated plates, and anchor bolts. The synthetic rubber anti-blocking blocks are made of a high-elasticity polymer, are positioned between H-shaped posts and corrugated plates, have a slot on their back, and the top of the posts is inserted into the slot. The corrugated plates are connected by bolts, and are fixed to the front of the synthetic rubber anti-blocking blocks by anchor bolts.
[0007] Furthermore, the synthetic rubber anti-blocking block is a hollow structure or a solid structure. When the synthetic rubber anti-blocking block is a hollow structure, it has an open bottom. The synthetic rubber anti-blocking block and the corrugated plate are provided with bolt holes and are connected by anchor bolts. When the synthetic rubber anti-blocking block is a solid structure, the anchor bolt is a self-tapping screw. After the anchor bolt passes through the corrugated plate, it is driven into the synthetic rubber anti-blocking block to form a connection.
[0008] Furthermore, the synthetic rubber anti-blocking block is provided with several L-shaped buckles on its back, respectively located on the top and side, forming a slot space with the back of the synthetic rubber anti-blocking block, which matches the cross-section of the column.
[0009] Furthermore, the cross-sectional shape of the column is a groove or an I-shape, with the opening of the groove facing the direction of the vehicle travel.
[0010] Furthermore, the material of the synthetic rubber anti-blocking block has flame-retardant properties.
[0011] Furthermore, the synthetic rubber anti-blocking block is compressed and deformed under force. After the column bends, the synthetic rubber anti-blocking block slides out from the top of the column along the slot, and the connection between the synthetic rubber anti-blocking block and the corrugated plate is disengaged.
[0012] By adopting the above technical solution, this utility model has the following beneficial effects:
[0013] (1) Synthetic rubber materials do not cause pollution to the environment and are environmentally friendly;
[0014] (2) Synthetic rubber anti-collision blocks are elastic, which better absorbs and disperses collision energy;
[0015] (3) Synthetic rubber anti-blocking blocks are resistant to aging and corrosion, extending their service life. Attached Figure Description
