Description

Technical Field

[0001] The patent of this invention relates to technical fields such as road engineering, bridge engineering and municipal engineering, and specifically is an assembled lightweight and high-strength fiber composite guardrail with energy storage and lighting functions. Background Art

[0002] With the increase in traffic volume and vehicle speed, the requirements for road safety facilities are also increasing. New guardrails need to be able to absorb collision energy more effectively, reduce the degree of injury in accidents, and consider how to better guide out-of-control vehicles back to their normal driving paths in design. Traditional guardrail materials such as galvanized steel plates are prone to oxidation and rust, high cost, and possible pollution during the production process. They are prone to damage in the event of a vehicle collision, causing the vehicle to deviate to the opposite lane and cause a secondary accident.

[0003] Therefore, it is necessary to develop new materials that have better weather resistance, corrosion resistance and environmental protection performance while maintaining low costs. New guardrails need to maintain good physical properties and service life in various environments. And as society's awareness of environmental protection increases, it is becoming increasingly important to develop recyclable or easy-to-maintain guardrail products. This will not only help reduce long-term operating costs, but also help promote the construction of a resource-saving society.

[0004] In addition, most existing road guardrails lack warning devices and lighting facilities, which makes it difficult for drivers to see clearly at night or in dim conditions, thus causing traffic accidents. In order to solve the problems of existing galvanized steel guardrails, the present invention provides an assembled lightweight high-strength fiber composite material guardrail with energy storage and lighting functions, which can replace traditional galvanized steel guardrails and provide a new lightweight, high-strength and durable road separation device with both energy storage and lighting functions. Summary of the invention

[0005] To solve the above problems, the present invention discloses an assembled lightweight and high-strength fiber composite guardrail with energy storage and lighting functions, which not only improves the safety and durability of the guardrail, but also shows obvious advantages in economy and environmental protection, providing a more ideal solution for the construction of modern transportation infrastructure.

[0006] An assembled FRP guardrail with energy storage and lighting functions includes assembled FRP columns that can be assembled in blocks; the assembled FRP columns are composed of assembled FRP column bodies and assembled FRP column caps; assembled FRP crossbars, which are composed of two assembled FRP beams and FRP columns, and are arranged horizontally between the two assembled FRP columns and connected thereto; a solar energy collection device; an energy storage device; a lighting device; a traffic warning device 6; an interconnected circuit control system 7; and lightweight high-strength FRP bolts. When installing the guardrail, the assembled column bodies are installed on the ground at a certain interval (1.5m), and then installed in sequence from bottom to top. When a part of the guardrail is damaged by impact, the staff can remove the damaged part separately to avoid overall replacement, which is convenient for installation and maintenance and can effectively improve work efficiency.

[0007] An assembled FRP crossbar is installed between two assembled FRP columns, and each assembled FRP crossbar is composed of an assembled FRP crossbeam and an FRP column. Each set of guardrails is provided with two assembled FRP columns, with a spacing of 1.5m. Three FRP columns 22 are provided in each assembled FRP crossbar, and the average spacing between the FRP columns 22 is not greater than 0.4m. The assembled FRP crossbar can provide strong resistance to prevent the vehicle from deviating to the opposite lane after being hit and causing a secondary accident, which can improve safety performance.

[0008] Furthermore, the lightweight and high-strength fiber composite material referred to in the present invention is made of materials such as continuous fiber mesh, continuous fibers, inorganic substrate and additives, and the continuous fiber mesh and continuous fibers are made of one or more materials such as carbon fiber, basalt fiber, glass fiber, aramid fiber, polyethylene fiber and the like.

[0009] Furthermore, the inorganic substrate of the lightweight and high-strength fiber composite material referred to in the present invention is inorganic polymer resin (geopolymer resin), phosphate resin, titanate resin and other materials.

[0010] Furthermore, during the preparation process of the lightweight high-strength fiber composite material referred to in the present invention, a plurality of continuous fiber grids are first stacked together in different grid directions, and then the fibers are vertically inserted into the grids, and then immersed in an inorganic substrate to ensure that the fibers are in full contact with the inorganic substrate.

[0011] Furthermore, in the present invention, the outer surfaces of all FRP materials are sprayed with refractory coatings.

[0012] Furthermore, the interconnected circuit control system and energy storage device of the present invention are located inside the assembled FRP base.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The guardrail has high strength and long service life.

[0014] The present invention uses lightweight, high-strength and durable fiber-reinforced composite materials (FRP) to replace traditional galvanized steel. The density of FRP material is only 1250~2100 kg / m³, which is about 1 / 6~1 / 4 of the density of steel, which greatly reduces the overall weight, making the guardrail more convenient during installation and transportation, and reducing the construction difficulty and cost. More importantly, the tensile strength of FRP material can exceed 3000 MPa, which is much higher than the tensile strength of traditional steel, ensuring that the guardrail can provide more reliable protection in extreme situations such as vehicle collisions.

[0015] In addition, FRP materials have excellent corrosion resistance and can effectively resist the erosion of moisture, salt and other chemicals in the atmosphere, avoiding the common oxidation and rusting problems of traditional metal guardrails and the frequent maintenance requirements they bring, significantly extending the service life of the guardrails. Therefore, the present invention not only improves the safety and durability of the guardrail, but also shows obvious advantages in terms of economy and environmental protection, providing a more ideal solution for the construction of modern transportation infrastructure.

[0016] 2. Use clean energy for power supply and lighting, which is energy-saving and environmentally friendly.

[0017] The present invention can fully utilize solar energy resources by integrating an efficient solar energy collection device, converting it into electrical energy, and providing stable and reliable power support for road lighting systems and traffic warning systems. This method not only effectively saves traditional power resources and reduces dependence on fossil fuels, but also greatly reduces carbon emissions and contributes to environmental protection. As a renewable resource, the use of solar energy will hardly generate additional operating costs and has significant economic benefits in the long run. At the same time, the present invention achieves the purpose of making more full use of solar energy by setting a steering system.

[0018] The lighting system and traffic warning system of the present invention complement each other and improve the safety of the road. The reasonable layout of the lighting system ensures the visibility of the road at night and in bad weather conditions, so that the driver can more clearly identify the road condition information.

[0019] In summary, the use of solar energy to power road facilities not only embodies the concept of sustainable development, but also makes a positive contribution to building a greener and safer urban traffic environment by improving road safety levels.

[0020] 3. The use of prefabricated structure can save costs and improve work efficiency.

[0021] The present invention focuses on the two key points of cost saving and improving work efficiency, and innovatively proposes a design scheme for assembled railings. All components are pre-manufactured in the factory to ensure high quality and consistency. This factory production method can not only strictly control the quality of materials, but also improve production efficiency and reduce waste through standardized processes.

[0022] These prefabricated components can be flexibly adjusted according to the specific conditions of the site, without the need for secondary processing, thus significantly shortening the construction period. The modular design makes the installation process easier and faster, reduces the need for complex operations on site, and reduces the reliance on skilled workers. In addition, since the components have been prefabricated, only simple assembly work is required on site, which not only speeds up the project progress, but also reduces on-site operation time, effectively reducing labor and material costs.

[0023] In addition, prefabricated railings also have obvious advantages in maintenance and updating. If a component needs to be replaced or repaired, it can be quickly disassembled and replaced with a new prefabricated component without making large-scale changes to the entire system. This flexibility not only facilitates daily maintenance, but also extends the service life of the entire guardrail system, further improving economic benefits.

[0024] 4. Excellent fireproof performance and environmentally friendly.

[0025] The present invention uses a lightweight, high-strength and durable fiber-reinforced composite material (FRP) to replace traditional galvanized steel. The mechanical properties of traditional steel will drop sharply when encountering a fire caused by a traffic accident, resulting in insufficient resistance and easily causing secondary accidents. The base used in traditional FRP materials is flammable, and the above problems will also occur; traditional bases are mostly polyester, vinyl, and epoxy materials. Once burned, they will release a large amount of toxic and harmful gases, affecting environmental safety, so there are certain challenges in using FRP guardrails. In this design, the FRP base uses inorganic resins (inorganic polymer resins, magnesium oxychloride cement, etc.) to replace commonly used organic resins, and at the same time, the fire retardant coating is sprayed on the outside of the structure to improve the overall fire resistance of the present invention. At the same time, FRP materials are prone to aging under long-term ultraviolet irradiation, and spraying coatings can also reduce direct ultraviolet radiation and slow down the aging process.

[0026] 5. The level of intelligence and informatization has been improved.

[0027] Traditional road guardrails cannot function in the event of a traffic accident, which will affect the normal driving of vehicles behind for a period of time after the accident, and easily cause secondary accidents. The present invention can transmit location information and collision severity information to the system as soon as a traffic accident occurs by setting sensors and communication systems, so that personnel can be notified to handle the scene in a timely manner, and the color of traffic warning lights can be changed to warn vehicles behind to pay attention to safety.

The base of the light high-strength composite material of the present invention is made of inorganic material and the surface is sprayed with fire retardant coating.

The lighting device 5 is fixed on the assembled FRP column 1 and the assembled FRP crossbar 2. The structure is assembled as a whole, and bolts are used at the interfaces. The bolts used are all lightweight and high-strength FRP bolts 8. Under normal working conditions, the solar panel 31 collects solar energy and converts it into electrical energy, and transmits the converted electrical energy to the energy storage device 4 through wires.
