Description

Technical Field

[0001] This utility model relates to the field of anti-glare panel technology, and in particular to an anti-glare panel made of phosphogypsum modified material. Background Technology

[0002] Anti-glare panels are traffic safety facilities installed on the median barrier of highways, primarily used to address the glare from oncoming vehicle headlights, thereby improving driving safety and comfort. Based on the material, existing anti-glare panels are mainly divided into three categories: steel anti-glare panels, fiberglass anti-glare panels, and plastic anti-glare panels. However, these traditionally made anti-glare panels all have varying degrees of technical problems in practical applications, as detailed below:

[0003] Steel anti-glare panels are rarely used nowadays due to their heavy weight, susceptibility to rust, and potential for secondary injuries. While fiberglass anti-glare panels are lightweight, they are brittle and prone to cracking or breaking upon impact with a vehicle or strong winds; the resulting sharp fragments can pose a road safety hazard. Plastic anti-glare panels are lightweight and inexpensive, but their impact resistance is poor, making them unsuitable for long-term safety. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides an anti-glare panel made of phosphogypsum modified material.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A phosphogypsum modified material anti-glare panel includes a phosphogypsum anti-glare panel and an anti-glare panel base. The phosphogypsum anti-glare panel is a flat rhomboid structure, and the anti-glare panel base is a plate body. The bottom of the phosphogypsum anti-glare panel is fixed to the anti-glare panel base. The anti-glare panel base is provided with through holes for bolts to pass through. The phosphogypsum anti-glare panels are spaced apart and fixedly installed on a concrete crash barrier or corrugated steel crash barrier by bolts passing through the anti-glare panel base.

[0007] Furthermore, the outer surface of the phosphogypsum anti-glare board is a reflective paint layer, and its interior is a mixture of phosphogypsum modified material and fiber material, or a mixture of phosphogypsum modified material and nylon mesh.

[0008] Furthermore, the phosphogypsum anti-glare board and the anti-glare board base are integrally formed.

[0009] Furthermore, the number of through holes on the anti-glare plate base is two or four; the bolt is a pull-out resistant expansion bolt.

[0010] Furthermore, several panel stiffening ribs are provided between the two sides of the phosphogypsum anti-glare board and the base of the anti-glare board.

[0011] Furthermore, the phosphogypsum anti-glare board, the panel stiffening ribs, and the anti-glare board base are integrally formed.

[0012] Furthermore, the anti-glare panels made of phosphogypsum modified material with panel stiffening ribs and the anti-glare panels made of phosphogypsum modified material without panel stiffening ribs are arranged alternately and fixed to the concrete crash barrier or corrugated steel crash barrier by bolts passing through the base of the anti-glare panel.

[0013] The beneficial effects of this utility model are:

[0014] The phosphogypsum-modified anti-glare panel has high overall strength and toughness, effectively resisting vehicle impacts and strong winds, reducing the risk of breakage or shattering; even if it breaks in extreme circumstances, it will not produce sharp fragments, avoiding secondary injuries to pedestrians and vehicles.

[0015] This phosphogypsum-modified anti-glare panel, through the use of bolts and a base, ensures a secure and reliable connection between the panel and the guardrail or crash barrier, enhancing overall installation safety. A reflective paint coating further enhances its weather resistance, maintaining stable appearance and function over a long period and reducing maintenance frequency. The phosphogypsum anti-glare panel features a flat, diamond-shaped structure that effectively blocks glare from oncoming headlights while reducing wind resistance and improving wind resistance. By incorporating fiber materials or nylon mesh to strengthen the structure and adding stiffening ribs to the panel to optimize stress distribution, the lifespan of the anti-glare panel is significantly extended.

[0016] The phosphogypsum modified material anti-glare board is integrally formed with the anti-glare board base. Both are made of phosphogypsum modified material. Phosphogypsum is a bulk industrial solid waste with low production cost and low pollution, which helps to promote the construction of green transportation infrastructure. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0030] To address the problems of steel anti-glare panels being heavy, prone to rusting and potentially causing secondary damage, fiberglass anti-glare panels being brittle and easily cracking or breaking when subjected to vehicle impacts or strong winds, and plastic anti-glare panels having poor impact resistance and being unsuitable for long-term use, this embodiment provides an anti-glare panel made of phosphogypsum modified material. By optimizing the material and structure, the above problems are solved, and efficient resource utilization of phosphogypsum solid waste is achieved.

[0031] Specifically, such as Figure 1 and Figure 2 As shown, the phosphogypsum modified material anti-glare panel includes two parts: a phosphogypsum anti-glare panel 1 and an anti-glare panel base 2. The phosphogypsum anti-glare panel 1 is the main load-bearing part, used to block the glare of oncoming vehicle lights, and at the same time bears wind loads and other external forces. The anti-glare panel base 2 is the basic component that connects the phosphogypsum anti-glare panel 1 to the guardrail or crash barrier, and plays a role in fixing and supporting it.

[0032] like Figure 2 and Figure 3 As shown, the phosphogypsum anti-glare panel 1 is a flat rhomboid structure with outwardly protruding edges on its left and right sides, an upwardly protruding edge on its top, and arc-shaped outward protrusions on its front and rear sides. This structure facilitates demolding, effectively blocks glare from oncoming vehicle headlights, reduces wind resistance, and improves wind resistance. The anti-glare panel base 2 is a hexagonal plate structure adapted to the phosphogypsum anti-glare panel 1, with through holes at the bottom for bolts 4 to pass through and connect to the concrete crash barrier 5 or the corrugated steel crash barrier 7.

[0033] During manufacturing, phosphogypsum, modifier, and water are mixed in a specific ratio and then poured into a mold. After stirring, compaction, curing reaction, and hardening, the mold is removed to obtain an integrally formed phosphogypsum-modified anti-glare panel 1 and anti-glare panel base 2. During the mixing process, fiber materials or nylon mesh can be added to create a mixture of phosphogypsum-modified material and fiber materials or nylon mesh, enhancing overall strength and toughness. After demolding, the integrally formed phosphogypsum-modified anti-glare panel can be coated with a reflective paint layer to improve nighttime driving safety and further enhance weather resistance and anti-aging properties.

[0034] This embodiment provides two installation methods for phosphogypsum-modified anti-glare panels, for selection in actual engineering projects:

[0035] Method 1, such as Figure 4 , Figure 5 and Figure 6 As shown, the anti-glare plate base 2 has two through holes through which the bolts 4 pass. The bolts 4 are pull-out resistant expansion bolts. The anti-glare plate base 2 is connected to the concrete crash barrier 5 on the road surface 6 by passing the bolts 4 through the bolts 4, thereby fixing the phosphogypsum anti-glare plate 1 to the concrete crash barrier at intervals.

[0036] Based on Method 1, if the phosphogypsum-modified anti-glare board still cannot meet the shear resistance requirements in actual engineering, such as Figure 7 , Figure 8 and Figure 9 As shown, the required number of panel stiffening ribs 3 are provided between the two sides of the phosphogypsum anti-glare board 1 and the anti-glare board base 2. In the figure, two panel stiffening ribs 3 are provided on each side of the phosphogypsum anti-glare board 1. The phosphogypsum anti-glare board 1, the panel stiffening ribs 3 and the anti-glare board base 2 are integrally formed.

[0037] If the actual engineering project still requires increased shear resistance, such as Figure 10As shown, the anti-glare plate base 2 can also be provided with four through holes for the bolts 4 to pass through. The bolts 4 are pull-out resistant expansion bolts. The anti-glare plate base 2 is connected to the corrugated anti-collision steel guardrail beam 72 on the corrugated anti-collision steel guardrail post 71 embedded in the road surface 6 by the bolts 4 passing through it, thereby fixing the phosphogypsum anti-glare plate 1 to the corrugated anti-collision steel guardrail 7 at intervals. The number of through holes and bolts 4 on the anti-glare plate base 2 is set according to the shear resistance requirements in the actual project. The more bolts 4 there are, the greater the shear strength.

[0038] In addition, such as Figure 11 As shown, in actual engineering, anti-glare panels made of phosphogypsum modified material with panel stiffening ribs 3 and anti-glare panels made of phosphogypsum modified material without panel stiffening ribs 3 can also be arranged in a cross manner, and fixed to the concrete anti-collision wall 5 or corrugated anti-collision steel guardrail 7 by bolts 4 passing through the anti-glare panel base 2.

[0039] In summary, the phosphogypsum-modified anti-glare panel 1 of this anti-glare panel utilizes a flat, rhomboid structure composed of phosphogypsum-modified material and fiber material or nylon mesh, integrally molded with the anti-glare panel base 2. This significantly enhances the overall strength and toughness, effectively resisting vehicle impacts and strong winds, reducing the risk of breakage or fragmentation. Even in extreme cases of damage, it will not produce sharp fragments, avoiding secondary injuries to pedestrians and vehicles. After applying a reflective paint layer, its weather resistance and anti-aging properties are significantly improved, resulting in a long service life and low maintenance frequency. Furthermore, using phosphogypsum, a major industrial solid waste, as the main raw material results in low production costs and minimal pollution, promoting the construction of green transportation infrastructure.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
