Description

Technical Field

[0001] This utility model relates to the field of highway sign technology, and specifically to a highway sign. Background Technology

[0002] Highway signboards are traffic information transmission devices installed along roads. They typically use eye-catching colors, simple graphic symbols and text to provide drivers and pedestrians with key information such as road names, directional guidance, distance information, speed limits, warnings and service facility locations. They are important infrastructure for ensuring road traffic safety, regulating traffic order and improving traffic efficiency, and are widely used in various traffic scenarios such as highways, urban roads and rural roads.

[0003] Most road signs on the market are made of aluminum plates welded together with an aluminum frame, which makes them heavy and inconvenient to install. At the same time, their insufficient hardness makes them prone to deformation. When subjected to strong external forces, the signs are easily deformed, and the greater the deformation, the more serious the tendency to peel and corrode. In addition, due to the low melting point and soft texture of the material, it will deform in high-temperature environments. Welding not only results in low reliability but also produces large weld spots that are difficult to grind smooth. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0031] like Figures 1-6 As shown, in one embodiment, a road signboard includes: a signboard body 1;

[0032] The signboard body 1 includes an inner core layer 11, which is covered by a panel layer 12. Its main function is to allow staff to print various traffic information (such as road names, directional guidance, speed limits, etc.) so that passing drivers and pedestrians can clearly obtain relevant traffic guidance information.

[0033] For example, the inner core layer 11 is a thermoformed honeycomb core layer with polypropylene (PP) as the main material. Polypropylene itself has the characteristics of being lightweight, chemically stable, and impact-resistant. The thermoformed honeycomb core layer can reduce its own weight to the greatest extent while ensuring excellent support performance, so that the inner core layer 11 can distribute stress more evenly when subjected to external impact, thereby improving the overall impact resistance. The panel layer 12 is a continuous fiber prepreg tape layer with glass fiber (glass fiber) and polypropylene (PP) as the main raw materials. Glass fiber has extremely high strength and stiffness, which can significantly improve the structural strength and hardness of the panel layer 12 and effectively resist external friction, collision and other damage. Polypropylene, as the matrix material, is consistent with the main material of the inner core layer 11. This not only ensures good compatibility between the panel layer 12 and the inner core layer 11, which is convenient for subsequent composite molding, but also allows the panel layer 12 to maintain stable performance in various complex environments by taking advantage of the good weather resistance and processing performance of polypropylene. At the same time, it provides a flat and suitable surface substrate for printing prompt information. Specifically, the indicator panel body 1 is formed by hot pressing and composite molding of an inner core layer 11 and an outer panel layer 12.

[0034] It is understood that the highway sign body 1 of this application is made by hot-pressing a composite integral molding process using a vacuum-formed honeycomb inner core layer 11 covered with a continuous fiber prepreg tape panel layer 12. This process can effectively reduce the overall weight while ensuring structural strength, and also has high corrosion resistance and weather resistance. Furthermore, it can be recycled and reused, effectively reducing the cost of use.

[0035] It should be explained in detail that, due to the unavoidable presence of numerous burrs around the edges of the signboard made from thermoplastic honeycomb panels after molding. These burrs not only affect the overall quality of the product, resulting in uneven edges that may scratch people or other objects during transportation or installation, but also detract from the product's aesthetics. Therefore, it is necessary to use grinding equipment to smooth the edges of the signboard body 1 into a curved surface (e.g., ...). Figure 2 As shown, the top and bottom edges of the indicator panel body 1 are smooth, arc-shaped surfaces with symmetrical curvature.

[0036] Please continue reading. Figures 1-6 An embedded part 2 is installed on the indicator plate body 1 to connect the indicator plate body 1 and the mounting frame; and an adhesive layer 3 is welded on the embedded part 2 to make the embedded part 2 and the indicator plate body 1 form an integral structure by hot pressing.

[0037] For example, the embedded part 2 includes a metal sheet 21, and a connector 22 is installed in the middle of the metal sheet 21;

[0038] Specifically, the indicator plate body 1 has a positioning groove 13 on its end face, and the embedded part 2 is inserted into the positioning groove 13; wherein, the metal sheet 21 includes a main body 211, and multiple sets of the main body 211 are symmetrically arranged; correspondingly, an annular groove 212 is provided in the middle of the main body 211, and multiple sets of the annular groove 212 are symmetrically arranged, which can enhance the uniformity of force on the metal sheet 21 and the overall stability.

[0039] Furthermore, the connector 22 passes through the middle of the main body 211 and is rotatably connected to the main body 211, which improves the flexibility of installation. Correspondingly, the adhesive layer 3 is provided with a mounting hole 31 in the middle, and the adhesive layer 3 is fitted onto the connector 22 through the mounting hole 31, thereby achieving precise fit and connection between the adhesive layer 3 and the embedded part 2.

[0040] Specifically, the thickness of the adhesive layer 3 is 5-15% of the thickness of the indicator plate body 1. The adhesive layer 3 is hot-pressed and welded to the indicator plate body 1 to ensure a tight bond between the two and guarantee the strength of the connection.

[0041] It is important to explain in detail that traditional connection methods, such as mechanical connections (bolt connections, riveting, etc.), will have through holes in the indicator plate, which will disrupt the continuity of the material, leading to stress concentration and reduced structural strength. While adhesive bonding does not damage the fibers, it has problems such as high environmental requirements, low interfacial bonding strength, and long-term reliability being greatly affected by factors such as temperature and humidity. In addition, the PP resin commonly used in thermoplastic composite boards has a non-polar surface and therefore has high crystallinity, resulting in poor adhesion at room temperature. Furthermore, when directly hot-pressing and welding metal parts, the difference in thermal expansion coefficients between the metal and the composite material causes delamination at the interface, and high load-bearing capacity cannot be achieved.

[0042] It is understandable that the highway signboard body 1 is equipped with embedded parts 2 through positioning groove 13, and then an adhesive layer 3 of the same material as the signboard body 1 is applied and then the whole is hot-pressed and welded. The whole is formed by pressing and holding the welding with heating equipment, which can effectively improve the installation efficiency, improve the mechanical properties without destroying the continuity of the material.

[0047] In actual product verification, the structural column limit values ​​(diameter * wall thickness mm) of the above-mentioned 3003 aluminum plate product are 235*10mm, and the structural beam limit values ​​(diameter * wall thickness mm) are 113*8mm; correspondingly, the structural column limit values ​​(diameter * wall thickness mm) of the signboard of this application are 230*10mm, and the structural beam limit values ​​(diameter * wall thickness mm) are 110*8mm; therefore, the cost of the corresponding support structure of the signboard can be effectively reduced.

[0048] Through the above technical solution, this application achieves structural strength and hardness approximately twice that of traditional aluminum plates, effectively resisting external impacts and reducing deformation. Simultaneously, the overall weight is effectively reduced, facilitating transportation and installation. Furthermore, it possesses high corrosion resistance, resisting erosion from rainwater and airborne pollutants, maintaining stability under various climatic conditions. Moreover, it can be recycled and reused, reducing resource waste and significantly lowering usage costs, making it more affordable than aluminum plates.
