Description

Technical Field

[0001] The utility model relates to the technical field of design and manufacturing of urban road guardrails, in particular to an urban road guardrail based on a new PDCPD composite material. Background Art

[0002] Urban road guardrails play a vital role in road traffic safety. Existing urban road guardrails are mostly made of metal or traditional concrete. These materials have disadvantages such as heavy weight, easy deformation, and poor weather resistance, and they also pose certain safety risks on urban roads. For example, road guardrails made of concrete are typically composed of arranged concrete piers, often with protruding edges and corners. Road guardrails made of metal materials, on the other hand, typically consist of columns and guardrail panels installed between the columns, with the panels typically being made of multiple pipes connected together.

[0003] With the guardrail structures of the above two prior arts, once a traffic accident occurs, these guardrail pieces can easily cause secondary injuries to passengers, so there is still a great safety hazard.

[0004] Therefore, it is necessary to find a new material and an improved guardrail structure to improve the performance and reliability of urban road guardrails. Summary of the Invention

[0005] The purpose of the utility model is to provide an urban road guardrail based on a new PDCPD composite material, which is easy to install and has stable performance, so as to solve the safety hazard of the existing technology that easily causes secondary casualties to passengers in automobile accidents.

[0006] The purpose of this utility model is achieved through the following technical solutions:

[0007] An urban road guardrail based on a new PDCPD composite material includes: a plurality of guardrail pieces, a plurality of columns, a plurality of advertising display boards and a plurality of flower boxes. The guardrail pieces, columns, advertising display boards and flower boxes are independent structural members made of PDCPD materials through different molds. The four corners of the guardrail pieces are arc corners, and an advertising display panel is formed in the middle of the guardrail piece. The top of the column is provided with a base, and the bottom of the advertising display board is provided with a first base adapted to the base, so that the advertising display board can be detachably installed by matching the first base with the base. At the upper end of the column, the bottom of the flower box is provided with a second base adapted to the base, so that the flower box can be detachably mounted on the upper end of the column by cooperating the second base with the base, a first mounting seat is provided on both sides of the guardrail piece, and a second mounting seat matching the first mounting seat is provided on both sides of the column, N guardrail pieces and N+1 side surfaces of the column are connected in sequence and connected together through the first mounting seat and the second mounting seat matching each other on the connected side surfaces to form the urban road guardrail, and the columns are provided at both ends of the urban road guardrail, and N≥1.

[0008] PDCPD (polydicyclopentadiene) is extracted from petroleum intermediates and has the characteristics of light weight, high hardness, not easy to deform and good weather resistance. The utility model proposes an urban road guardrail based on a new PDCPD composite material. It is the first time that PDCPD material is applied to the manufacture of urban road guardrails. The four corners of the guardrail sheet are designed with rounded corners. Unlike conventional guardrail sheets with protruding edges, the design of the utility model has no sharp edges that can hurt people, and can effectively prevent pedestrians from being injured, solving the safety hazard of road guardrails causing secondary casualties to passengers in car accidents. It is made into standard prefabricated parts through molds, so that it can be assembled into urban road guardrails of different lengths according to specific application requirements. A base is set at the top of the column, and the bottom of the advertising display board and the flower box are both provided with a base adapted to the base, so that the user can design the top of the column into an advertising display board or a flower box according to actual needs, and it can be replaced as the use requirements change, so that it can be combined into cultural guardrails, welcome guardrails, publicity guardrails, etc. according to different roads, different cities, and different functional requirements. At the same time, an advertising display panel is set on the guardrail sheet, which is also a diversified application of the function of the guardrail sheet.

[0009] The urban road guardrail based on the new PDCPD composite material proposed in this utility model has more stable performance, safer use, easier installation and better decorative effect than the existing technology, and can be widely used in the fields of urban road traffic safety and urban road beautification.

[0010] Wherein, a first mounting hole is provided on the first mounting seat, and a second mounting hole is provided on the second mounting seat. When the first mounting seat and the second mounting seat are matched together, the first mounting hole is aligned with the second mounting hole, and the guardrail plate and the column are fixed with bolts to the aligned first mounting hole and second mounting hole.

[0011] Preferably, the first mounting seat and the guardrail piece are integrally formed.

[0012] Preferably, the second mounting seat and the column are integrally formed.

[0013] Preferably, the flower box is a box-type structure with an open top, and various bouquets can be placed inside for welcoming decoration, etc.

[0014] The first base and / or the second base may be fixed to the base via a slot or a bolt. BRIEF DESCRIPTION OF THE DRAWINGS
