Description

Technical Field

[0001] The utility model relates to the technical field of road traffic safety facilities, in particular to a railway guardrail with a novel structural composite material. Background Art

[0002] With the development of railway transportation industry, railway guardrails, as important facilities to ensure the safe operation of railways, have higher and higher performance requirements. Existing railway guardrails are mainly designed with concrete structure or steel structure, but there are many problems.

[0003] First, concrete guardrails are prone to peeling of the protective layer, exposed reinforcement, crushing or even breaking due to wind erosion, weathering and corrosion, which affects their service life and safety. In addition, concrete guardrails are heavy, the installation process is complex, and the construction period is long. Large hoisting equipment is usually required to assist in installation, which increases the difficulty and cost of construction. Although steel guardrails perform better than concrete guardrails in some aspects, they are prone to paint peeling and rusting and aging in exposed and corrosive environments, which also leads to a large workload and high cost for maintenance.

[0004] Secondly, the existing guardrails have complex structures and are inconvenient to install. The installation of traditional guardrails usually requires multiple steps and complex connectors, which increases construction time and labor costs. At the same time, the maintenance and repair of existing guardrails are also cumbersome, especially when parts need to be replaced, the operation is inconvenient, which increases the difficulty and cost of maintenance.

[0005] In view of the above problems, the utility model provides a new type of structural composite material railway guardrail. By optimizing the guardrail structure design, the installation process is simple, maintenance and replacement are convenient, and it can cope with changes in environmental temperature differences, thereby improving the service life and safety of the guardrail.

[0028] The utility model provides a new type of structural composite material railway guardrail, which has the following beneficial effects:

[0029] First of all, the utility model is made of glass fiber polyurethane composite material. Except for bolt fasteners, the main components of the guardrail are all made of this material; glass fiber polyurethane has excellent mechanical properties, wear resistance and corrosion resistance, can effectively resist the erosion of environmental factors, and ensure the long service life of the guardrail; in addition, the material is light in weight and does not require the assistance of large-scale lifting equipment during the installation process. It can be installed by manpower or light machinery, which greatly simplifies the installation process and improves the installation efficiency.

[0030] Secondly, the utility model has a simple guardrail structure and a convenient installation process. The main structure of the guardrail is divided into three parts: a column, a handrail and a railing. The parts are connected by bolts and fixing blocks, which is convenient for quick installation and future maintenance and replacement. During the installation process, the column fixing block and the column base are fastened by bolts, the column rod is fixed to the column fixing block by self-tapping screws, and then the connecting rod of the handrail and the railing is fixed. The whole process does not require complex tools and equipment, and the installation is quick and convenient. During maintenance, you only need to remove the bolts fixing the handrail connecting rod and the bottom of the railing connecting rod to remove the handrail part, and unscrew the base self-tapping screws to remove the column rod, which greatly simplifies the maintenance steps and reduces maintenance costs.

[0031] Finally, the guardrail of the utility model has stability and adaptability in structural design. In the column structure, the screw fixes the handrail connecting rod and the railing connecting rod. The top of the screw is self-locked with a connecting plate through two nuts to ensure that the screw remains in a vertical state. This design not only limits the axial displacement of the handrail connecting rod and the railing connecting rod, but also limits their rotation, while strengthening the connection stability between the column and the base. The bottom of the connecting rod of the handrail and the railing is designed with a grooved countersunk hole to hide the bolts, reduce the erosion of the bolts by wind, sand and rain, and extend the maintenance cycle. The grooved long hole design of the connecting hole can also cope with the expansion and contraction of the bridge caused by temperature difference, ensuring the adaptability and safety of the guardrail in various environments.
