Description

Technical Field

[0001] The utility model relates to the field of road traffic safety signs, in particular to a road stud with adhesive backing. Background Art

[0002] Raised road markers, commonly known as road spikes, are commonly found as raised markers fixed to the road surface to serve as road markings. They can be used on highways and other roads to mark centerlines, lane dividers, and edge lines. They can also be used to mark dangerous sections such as curves, on-ramps, guide lines, road narrowings, and road obstacles. They are generally used in conjunction with road markings or to simulate road markings to supplement or replace traffic hazards posed by unclear road markings and roadside boundaries in low-visibility conditions such as at night. They provide a highly visible and recognizable visual warning. Road spikes are typically mechanically fixed to the road surface or the facade of traffic facilities using rivets or screws. While they provide a strong anti-slip function, they must withstand the impact and rolling of tires, especially on the road surface. However, the rigidity of the nailing method provides little cushioning, exposing the spikes to friction and impact from the tires, which can easily damage or even break them. This leaves bare, sharp nails on the road surface, increasing the risk of punctures. Furthermore, nailing the spikes increases road construction costs and is inefficient. Therefore, gluing the spikes has become a new method for laying spikes. The existing gluing method involves applying AB glue separately to the spike body and the road surface. Because both are rigid, the bond strength is insufficient, and the adhesive's fluid properties require a certain degree of fluidity, requiring large amounts of glue to be applied, resulting in high costs, time-consuming, labor-intensive construction, and low efficiency. Summary of the Invention

[0003] This application provides an adhesive-backed road stud to address the existing technical issues of low road stud installation efficiency, unreliable installation and fixing, easy displacement and falling off, lack of cushioning, and easy damage to the stud itself from impact and rolling. The road stud is waterproof and moisture-proof, vapor-resistant and alkali-resistant, light-shielding and anti-oxidant, and provides thermal insulation. Combined with a self-adhesive, soft, pressure-sensitive, non-drying rubber, it is suitable for attachment to rough and porous surfaces such as cement and asphalt roads, stone walls, and brick facades, providing durability and reliability.

[0004] A road spike with adhesive backing, comprising: a road spike base, the road spike base being in the shape of a solid trapezoidal platform, having a top surface and a bottom surface, and at least one reflective sheet groove on a side surface of the trapezoidal platform base;

[0005] A reflective sheeting having an array of retroreflective element units;

[0006] The rubber-based self-adhesive layer is composed of self-adhesive rubber; the rubber-based self-adhesive layer is bonded to the bottom surface of the road spike base, and the reflective sheet is embedded in the reflective sheet groove connected to the road spike base.

[0007] Furthermore, the spike base also includes a pair of finger gripping opening slots.

[0008] Furthermore, a supporting protrusion is provided inside the reflective sheet groove of the road stud base.

[0009] Furthermore, the pattern formed by the supporting protrusions constitutes a waterproof embossed pattern on the reflective sheet.

[0010] Furthermore, the pattern formed by the supporting protrusions is a unit X- or W-shaped transverse array forming an XXXX or WW pattern.

[0011] Furthermore, the plane shape of the reflective sheet groove is a rectangle or an isosceles trapezoid, and the shape is determined by the curved surface shape of a pair of side surfaces of the trapezoidal base of the road spike body and the plane shape of the other pair of side surfaces.

[0012] Furthermore, the retroreflective component unit array of the reflective sheet is a prism array.

[0013] Furthermore, the retroreflective element unit array of the reflective sheet is a micro-prism triangular pyramid array or a micro-prism micro-crystal cube pyramid array or an oblique cross-section triangular prism micro-triangular prism structure array.

[0014] Furthermore, the road spike substrate is an engineering plastic block, optionally a solid white or yellow block.

[0015] Furthermore, the reflective sheet is a high-transmittance polyester organic glass optical sheet, optionally a white, fluorescent yellow, orange or red organic glass optical sheet.

[0016] Furthermore, it further comprises a temporary backing layer, wherein the temporary backing layer is connected to the self-adhesive rubber, and the temporary backing layer is selected from a peelable release film or release paper.

[0017] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0018] 1. After removing the temporary removable backing from the bottom surface of the adhesive road stud of this application, the rubber-based self-adhesive layer attached to the bottom surface of the base can be used to directly adhere the road stud to the rough, porous surfaces of cement, asphalt pavement, and traffic facilities. The self-adhesive rubber is pressed into the cavities or holes of the rough, porous surface, increasing the contact area between the adhesive and the pavement, facade, and the surface of the object to be marked, creating a tight fit. Rubber has hydrophobic and self-repairing properties, and excellent physical and chemical properties such as thermal insulation, heat and water insulation, and oxidation resistance. This can reduce the influence of external environmental factors such as water, light, air, saline-alkali water vapor, and floating dust on the loss of adhesion, aging, and powdering of the contact area between the adhesive road stud and the construction surface. This improves the bonding strength and bonding life of the road stud to rough contact surfaces such as brick, stone, concrete, cement, and asphalt pavement, thereby increasing the efficiency of outdoor road studs.

[0019] 2. Compared to self-adhesive adhesives, the rubber-based self-adhesive layer of the self-adhesive road studs of this application is not fluid but slightly elastic. This not only effectively mitigates the mechanical rigidity between the hard texture of the road stud and the solid, hard road surface, thereby enhancing the durability of the bond between the two, but also provides a certain degree of cushioning when the road studs on the road surface are impacted by tires due to the presence of the elastic rubber, thereby reducing the degree of damage to the road studs to a certain extent and also reducing the effect of debonding and displacement of the road studs fixed to the road surface.

[0020] 3. The adhesive-backed road studs in this application are constructed from engineering plastic, effectively enhancing their overall impact and compressive load resistance. The side of the adhesive-backed road studs is inlaid with reflective sheeting, which offers excellent reflective properties. This passively illuminates the reflective sheeting, making the studs easier to identify and recognize at night and in low-visibility environments. This helps drivers distinguish and locate road markings or curb lines ahead, enhancing road safety and ensuring safe driving.

[0021] 4. The retroreflective elements of the reflective sheeting on the side of the adhesive-backed road studs of this application are arrayed using microscopic microprismatic pyramids, microcrystal cubes, or oblique-section triangular prism columns. Compared to traditional macroprismatic pyramid arrays of reflective sheeting, the micron-scale element size is extremely small, reducing the thickness of the reflective sheeting. Within the same reflective sheeting area, the increased number of retroreflective elements not only improves the uniform support force of the road stud base on the reflective sheeting and further reduces the destructive force of external tire pressure on the reflective sheeting, but also, if the retroreflective elements are damaged, the dark area on the reflective sheeting is smaller than the dark area caused by damaged reflector macroprisms, thereby maintaining the retroreflective performance of the reflective sheeting for a longer period of time.
