Description

Technical Field

[0001] This utility model belongs to the technical field of road traffic sign lines, and specifically relates to a novel road sign line structure. Background Technology

[0002] Traffic markings are signs on the road surface that use lines, arrows, text, vertical markings, raised pavement markers, and delineators to convey traffic information such as guidance, restrictions, and warnings to road users. Their function is to regulate and guide traffic; they can be used in conjunction with signs or used independently.

[0003] Existing road traffic markings include temporary and permanent traffic markings. Temporary traffic markings are often used during municipal engineering construction, with a minimum duration of about 1-2 weeks and a maximum duration of about 6 months. Generally, after the municipal engineering construction is completed, the temporary traffic markings need to be removed, and permanent traffic markings are repainted in the original road marking locations. However, the removal of existing temporary traffic markings is quite troublesome. Because temporary traffic markings are bonded to the road surface with adhesive, they are not easy to remove. Furthermore, existing removal methods, such as burning or high-pressure water washing, cause significant damage to the road surface. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of road marking structure to solve the problem mentioned in the background art that temporary traffic markings are not easy to remove and the removal process causes great damage to the road surface.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel road marking structure, comprising a road marking body, the road marking body comprising a paint layer, a sealing layer and an adhesive layer, the sealing layer being disposed between the paint layer and the adhesive layer, the interior of the sealing layer being filled with a self-heating layer, the bottom of the self-heating layer being in contact with the adhesive layer, and the road marking body being bonded and fixed to the road surface layer by the adhesive layer.

[0006] Preferably, the self-heating layer is limestone.

[0007] Preferably, the self-heating layer is mainly composed of iron powder.

[0008] Preferably, the coating layer contains self-luminous beads.

[0009] Preferably, the road marking body is provided with a connecting component, the connecting component including a connecting groove and a connecting block, the connecting groove and the connecting block being respectively disposed at both ends of the road marking body.

[0010] Preferably, the connecting groove is a dovetail groove.

[0011] Preferably, the connecting block is a dovetail block.

[0012] Preferably, the self-luminous bead is a fluorescent bead.

[0013] Preferably, the self-heating layer reacts with water to generate heat.

[0014] Preferably, the self-heating layer reacts with oxygen in the air to generate heat.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The present invention has a self-heating layer inside the road marking line. When the road marking line needs to be removed, the limestone inside the self-heating layer reacts with water to generate heat, or the iron powder polymer inside the self-heating layer reacts with oxygen in the air to generate heat. The heat generated by the self-heating layer is then used to heat the adhesive layer, thereby making it easier to remove the road marking line from the road surface and greatly reducing the damage to the road surface.

[0017] (2) The present invention is provided with a connecting component, which facilitates positioning during the bonding of road markings, avoids skewed bonding of road markings, improves the efficiency of bonding road markings, and reduces the difficulty of bonding road markings.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-2As shown, this utility model provides a technical solution: a novel road marking line structure, including a road marking line body 1, the road marking line body 1 including a paint layer 2, a sealing layer 3 and an adhesive layer 4, the sealing layer 3 being disposed between the paint layer 2 and the adhesive layer 4, the interior of the sealing layer 3 being filled with a self-heating layer 5, the bottom of the self-heating layer 5 being in contact with the adhesive layer 4, and the road marking line body 1 being bonded and fixed to the road surface layer 6 by the adhesive layer 4.

[0023] In the above technical solution, when it is necessary to remove the road markings, the heat generated by the self-heating layer 5 heats the adhesive layer 4, making the adhesive layer 4 easy to remove, thereby facilitating the removal of the road markings from the road surface and reducing damage to the road surface layer 6.

[0024] The self-heating layer 5 is made of limestone, and it generates heat by reacting with water.

[0025] When it is necessary to remove temporary road markings, use a removal tool to puncture the sealing layer 3, and then pour water into the punctured area. The water reacts chemically with the limestone, generating heat.

[0026] The self-heating layer 5 is a polymer synthesized from iron powder, vermiculite, activated carbon, inorganic salts and water. The self-heating layer 5 reacts with oxygen in the air to generate heat.

[0027] When it is necessary to remove the temporary road markings, use a removal tool to puncture the sealing layer 3. Then, air enters the self-heating layer 5 through the puncture. Iron powder reacts with oxygen in the air to generate iron oxide, while releasing heat.

[0028] Self-luminescent beads 7 are embedded in the coating layer 2. The self-luminescent beads 7 are fluorescent beads that emit fluorescence at night, making the road markings visible at night.

[0029] The main body 1 of the road marking is equipped with a connecting component, which includes a connecting groove 8 and a connecting block 9. The connecting groove 8 and the connecting block 9 are respectively located at both ends of the main body 1 of the road marking. The main body 1 of the road marking located in the middle has a connecting groove 8 and a connecting block 9 at both ends, while the main body 1 of the road marking located at the beginning and end only has a connecting groove 8 or a connecting block 9 at one end. The cooperation of the connecting groove 8 and the connecting block 9 facilitates positioning during the bonding of the road marking, avoids the road marking being bonded crookedly, and also improves the efficiency of bonding the road marking and reduces the difficulty of bonding the road marking.

[0030] The connecting groove 8 is a dovetail groove, and the connecting block 9 is a dovetail block. The cooperation between the dovetail groove and the dovetail block makes the connection between the two adjacent road marking bodies 1 more secure.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
