Description

Technical Field

[0001] The present invention relates to the technical field of road traffic safety facilities, and specifically refers to a steel plate oscillating marking line, which is mainly used in places such as highways, urban roads, and parking lots for dividing lanes, warning vehicles, etc., so as to improve road traffic safety. Background Art

[0002] Road markings are crucial in road safety, clarifying road rules, guiding vehicles and pedestrians, and effectively reducing traffic accidents. Currently, thermoplastic oscillating road markings are a widely used form of road marking. They incorporate materials like glass beads into thermoplastic paint to create a thick, raised marking. When vehicles run over it, they vibrate and make a sound, providing a warning.

[0003] However, existing thermoplastic oscillating road markings have numerous shortcomings. First, on heavily trafficked roads, thermoplastic road markings have poor durability, lasting only two to three months. This is due to frequent vehicle traffic, friction, and the effects of the natural environment, such as sun, rain, and temperature fluctuations, which cause the surface of the thermoplastic road markings to wear and peel, thus losing their intended warning function. Frequent replacement and maintenance not only increases road maintenance costs but also has certain impacts on traffic, such as traffic congestion during construction.

[0004] Secondly, the installation process of thermoplastic oscillating road markings is relatively complex. They require on-site heating and spraying, which not only requires specialized equipment and personnel but also consumes significant amounts of energy. Furthermore, the process also produces waste gas and residue, which pollutes the environment.

[0005] Furthermore, the vibration and sound effects of thermoplastic oscillating markings need to be improved. In actual use, due to limitations such as the raised height and structural design of thermoplastic markings, the vibration and sound produced are not obvious enough, and their function decays quickly during use. Since they are used in the middle of the road, on curves, at intersections, at highway toll booths, and on some dangerous sections of road, they are difficult to attract sufficient attention from drivers, thus affecting their warning effect.

[0006] To address these issues, the market urgently needs a road marking that is more durable, simple to install, environmentally friendly, and provides better warning effects. The present invention's oscillating steel plate marking is designed to address these issues, aiming to provide a road marking solution with superior performance. Summary of the Invention

[0007] The present invention aims to solve the above technical problems and provides a steel plate oscillation marking system.

[0008] In order to solve the above technical problems, the technical solution provided by the present invention is: steel plate oscillation marking, which is characterized in that: it comprises a number of steel plate units spliced ​​together, the steel plate unit is made of cold-rolled steel plate with a thickness of 1.8-2.2mm, and the size of a single plate is 180-220mm in width × 1200-1250mm in length; the surface of the steel plate unit is provided with an array-distributed groove structure, and the groove forms a raised portion with a height of 3-5mm on the back of the steel plate, and the projection size of the raised portion is 32-38mm×28-32mm, the center distance between adjacent raised portions is 50-55mm, and the edge raised portion is 25-30mm away from the short side of the steel plate unit and 18-22mm away from the long side.

[0009] Furthermore, the raised portion is a trapezoidal table-like structure, the top surface of which is a rectangular plane of 28-30 mm×25-28 mm, and the side surface forms an inclination angle of 115-125° with the plane of the steel plate.

[0010] Furthermore, the short sides of the steel plate units are provided with L-shaped interlocking edges, and the long sides are provided with slot-shaped oblong holes. Adjacent steel plate units are connected by nesting the interlocking edges and are fixed by positioning bolts passing through the oblong holes.

[0011] Furthermore, the surface of the cold-rolled steel plate is provided with anti-slip textures, which are composed of wavy grooves with a depth of 0.3-0.5 mm, and the direction of the grooves forms an angle of 45-60 degrees with the direction of vehicle travel.

[0012] Furthermore, reinforcing ribs are welded to the bottom surface of the steel plate unit. The reinforcing ribs are arranged at intervals of 200-250 mm along the length direction of the steel plate, and the cross-section is an isosceles triangle with a height of 8-10 mm.

[0013] Furthermore, the surface of the cold-rolled steel plate is plated with a zinc-nickel alloy layer, the thickness of the alloy layer is 80-100 μm, and the surface roughness Ra value is controlled in the range of 3.2-6.3 μm.

[0014] Furthermore, the four corners of the steel plate unit are provided with a rounded corner structure, the rounded corner radius is 15-20 mm, and the chamfer depth is 1.2-1.5 times the plate thickness.

[0015] Furthermore, elastic buffer pads are provided at the joints of adjacent steel plate units. The buffer pads are made of EPDM rubber, have a thickness of 3-5 mm, and a width covering 10-15 mm on both sides of the joint.

[0016] The advantages of the present invention compared with the prior art are:

[0017] 1. Durability: Compared to conventional hot-melt oscillating road markings, the steel plate oscillating road markings of this invention offer a service life of at least three years, maintaining excellent performance even on roads with heavy traffic. This is due to the high strength and wear resistance of the cold-rolled steel plate. Furthermore, the zinc-nickel alloy layer and rib reinforcement significantly extend its service life, reducing construction and maintenance intervals and lowering road maintenance costs.

[0018] 2. Excellent vibration and warning effects: The raised portion on the back of the steel plate is well designed, producing noticeable vibration and a louder, brighter sound, effectively attracting the driver's attention and improving driving safety. The anti-slip pattern further enhances the warning effect, allowing the driver to more clearly perceive the presence of the markings. It provides a good warning effect for key sections ahead, and it is a more functional highway facility.

[0019] 3. Simple installation and low cost: The steel plate units are connected through oblong holes, making the installation process simple and quick, without the need for specialized equipment and complex operations. Moreover, due to its long service life, the overall cost is not higher than that of existing hot melt oscillation markings.

[0020] 4. Environmental protection and energy saving: The steel plate oscillation marking of the present invention adopts cold processing throughout the process, without the need for heating and other energy-intensive processes, thus reducing energy consumption. At the same time, its raw materials are easy to purchase and can be recycled as metal materials, without causing pollution to the environment, thus meeting environmental protection requirements.

[0021] 5. Low transportation and logistics costs: Finished products are manufactured in the factory, with relatively small volume and weight, which makes them easy to transport and store, reducing transportation and logistics costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] 1. Working principle of the present invention:

[0029] A steel plate oscillating marking line, the specific structure of which is as follows:

[0030] The basic structure of the steel plate unit consists of several interconnected steel plate units 1, made of cold-rolled steel sheets with a thickness of 1.8-2.2 mm. The dimensions of a single steel plate unit 1 are 180-220 mm wide by 1200-1250 mm long. This size and thickness ensures the strength and stability of the steel plate unit while facilitating transportation and installation.

[0031] Grooved Structure and Raised Parts: The surface of the steel plate unit 1 is provided with an array of grooved structures. These grooves form raised parts 2 with a height of 3-5mm on the back of the steel plate. The projected dimensions of these raised parts 2 are 32-38mm x 28-32mm, with a center-to-center spacing of 50-55mm between adjacent raised parts 2. The raised parts 2 at the edges are 25-30mm from the short side of the steel plate unit and 18-22mm from the long side. This grooved structure design ensures that when a vehicle runs over the raised parts, they produce noticeable vibration and sound, providing a good warning effect.

[0032] The raised portion 2 has a trapezoidal structure, with a top surface that is a 28-30mm x 25-28mm rectangular plane, and its side surfaces forming an inclination angle of 115-125° with the plane of the steel plate unit 1. This trapezoidal design not only increases the strength of the raised portion but also optimizes the vibration and acoustic effects when a vehicle runs over it.

[0033] The connection structure of the steel plate units: The short sides of the steel plate units 1 are provided with L-shaped snap-fit ​​edges 3, and the long sides are provided with slot-shaped oblong holes 4. Adjacent steel plate units 1 are connected by nesting the snap-fit ​​edges 3 and fixed with positioning bolts passing through the oblong holes 4. This connection method makes the connection between the steel plate units more secure and also facilitates installation and removal.

[0034] Anti-slip texture: The surface of the steel plate unit 1 is provided with anti-slip texture 5. The texture is composed of wavy protrusions with a depth of 0.3-0.5mm, and the protrusions are oriented at an angle of 45-60 degrees with the vehicle's direction of travel. The provision of anti-slip texture can increase the friction between the vehicle and the marking, improving driving safety.

[0035] Reinforcement Ribs: Reinforcement ribs 6 are welded to the bottom surface of the steel plate unit 1. The ribs 6 are spaced 200-250 mm apart along the length of the steel plate unit 1 and have a cross-section that is an isosceles triangle with a height of 8-10 mm. The provision of reinforcement ribs can further improve the strength and stability of the steel plate unit and extend its service life.

[0036] Surface coating: The surface of the steel plate unit 1 is coated with a zinc-nickel alloy layer with a thickness of 80-100 μm and a surface roughness Ra value controlled within the range of 3.2-6.3 μm. The zinc-nickel alloy coating can improve the corrosion resistance of the steel plate and extend its service life in outdoor environments.

[0037] Rounded corners: The steel plate unit 1 has rounded corners with a radius of 15-20mm and a depth of 1.2-1.5 times the plate thickness. This rounded corner structure prevents the steel plate unit's corners from causing damage to vehicles and pedestrians, improving safety.

[0038] Elastic cushions: Elastic cushions are installed at the joints between adjacent steel plate units. Made of EPDM rubber, they are 3-5mm thick and extend 10-15mm wide on either side of the joint. These cushions reduce vibration and noise between the steel plate units when vehicles run over them. They also prevent rainwater from entering the joints, which could affect the service life of the steel plates.

[0039] When a vehicle runs over a steel plate vibration marking, the raised portion on the back of the plate contacts the tire, causing the tire to vibrate. The friction between the tire and the raised portion also produces a sound. This vibration and sound can attract the driver's attention, reminding the driver to pay attention to driving safety measures, such as slowing down and maintaining a safe distance.

[0040] The steel plate units are connected by nesting the L-shaped interlocking edges on the short sides, so that adjacent steel plate units can fit tightly together. At the same time, the oblong holes and positioning bolts on the long sides further fix the positions of adjacent steel plate units, ensuring the stability and firmness of the entire marking line.

[0041] The anti-skid patterns on the steel plate units increase friction with the tires, effectively preventing them from slipping when the vehicle is driving on the marked lines, thus improving driving safety. The anti-skid patterns are particularly effective in rainy days or on slippery roads.

[0042] The zinc-nickel alloy layer plated on the surface of the steel plate unit can form a protective film to prevent oxygen, moisture, etc. in the air from contacting the steel plate, thereby preventing the steel plate from rusting and corrosion and extending its service life.

[0043] Buffering principle: The elastic buffer pads at the joints of adjacent steel plate units can absorb the vibration and impact force generated by vehicle rolling over, reduce wear and damage between steel plate units, and at the same time reduce noise and improve driving comfort.
