Description

Technical Field

[0001] This utility model relates to anti-glare panels, and more particularly to an inverted S-shaped anti-glare panel that is easy to manufacture and suitable for areas with strong winds. Background Technology

[0002] Anti-glare panels are traffic safety products manufactured to address glare from oncoming vehicle headlights and installed on the central median strip of highways. They are mostly installed on or in the middle of the median guardrail, and some are also installed on movable guardrails with central openings. Anti-glare panels generally consist of a base and a panel body on the base. The panel body can be made of steel, plastic, or fiberglass. In terms of appearance, common types include straight panels, inverted S-shaped panels, embossed panels, and highway landscape panels. Inverted S-shaped panels are widely used due to their excellent optical performance. In deserts and coastal areas with strong winds, the performance requirements for anti-glare panels are extremely high. While steel anti-glare panels have good bending strength, they suffer from rapid salt spray corrosion and have a short service life in coastal areas. Fiberglass anti-glare panels experience a high rate of flexural modulus reduction after UV aging. Plastic anti-glare panels, while corrosion-resistant, suffer from low-temperature brittleness and weak wind load resistance.

[0003] Patent No. 114752160A, entitled "Formulation and Preparation Method of Polymer / Phosphogypsum Alloy Flame-Retardant Cable Tray," discloses the formulation and preparation method of a polymer / phosphogypsum alloy flame-retardant cable tray. The unit product contains the following components: 100 parts by weight of PVC, 80 parts by weight of phosphogypsum powder, 2.5-5 parts by weight of composite stabilizer, 9-16 parts by weight of processing aid, 6-10 parts by weight of impact modifier ACR61, 3-7 parts by weight of impact modifier CPE135, 4-6 parts by weight of impact modifier MBS56, and 1... The invention comprises 1-3 parts by weight of lubricant, 8-10 parts by weight of titanium dioxide, and 8-12 parts by weight of flame retardant. It possesses strong tensile strength, aging resistance, corrosion resistance, water resistance, oil resistance, acid and alkali resistance, and mold resistance. It also exhibits good impact resistance under high or low temperature conditions, enabling the effective utilization and consumption of phosphogypsum waste. If the PVC / phosphogypsum alloy system disclosed in this patent is applied to the anti-glare panel body, it will not only further enhance the effective utilization and consumption of phosphogypsum waste but also improve the performance of the anti-glare panel body, making it suitable for desert and coastal areas with strong winds.

[0004] Existing anti-glare plate bases have simple structures and poor strength, making them unsuitable for areas with strong winds, such as deserts and coastal regions. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide an inverted S-shaped anti-glare panel that is easy to manufacture and suitable for areas with strong winds, so as to solve the technical problems raised in the background art.

[0006] The objective of this utility model is achieved through the following technical solution: An easy-to-manufacture inverted S-shaped anti-glare panel suitable for areas with strong winds is disclosed. It comprises a base injection-molded from a polymer material and a polymer phosphogypsum anti-glare panel body on the base. The cross-section of the polymer phosphogypsum anti-glare panel body is inverted S-shaped. The base includes an elliptical base plate and two clamping plates with inverted S-shaped cross-sections. The two clamping plates are vertically and oppositely connected to the base plate, forming a mounting groove between them. The mounting groove is located axially along the major axis of the elliptical base plate and matches the lower end of the polymer phosphogypsum anti-glare panel body. The two clamping plates are connected to the polymer phosphogypsum anti-glare panel body by fasteners. The base plate is mounted on a guardrail using mounting components.

[0007] Furthermore, the bottom surface of the base plate is provided with multiple non-penetrating perforations.

[0008] Furthermore, a first reinforcing rib is connected between the side of the clamp plate facing away from the mounting groove and the base plate.

[0009] Furthermore, the main body of the polymer phosphogypsum anti-glare board is a thin-walled structure with a cavity, and multiple second reinforcing ribs are connected between the two sides in the width direction of the cavity.

[0010] Furthermore, the second reinforcing rib is plate-shaped, and multiple plate-shaped second reinforcing ribs are arranged at intervals along the width direction of the main body of the polymer phosphogypsum anti-glare board.

[0011] Furthermore, two arc-shaped plate-shaped reinforcing ribs with opposite openings are provided between the two plate-shaped second reinforcing ribs, and the two sides of the arc-shaped plate-shaped reinforcing ribs are respectively connected to the two sides of the main body of the polymer phosphogypsum anti-glare board in the thickness direction.

[0012] Furthermore, two arc-shaped plate-like reinforcing ribs form a ring.

[0013] Furthermore, the main body (2) of the polymer phosphogypsum anti-glare board has a width of 200mm, a thickness of 10mm, and a cavity thickness of 6mm.

[0014] Furthermore, the major axis of the elliptical base plate is 200mm and the minor axis is 130mm.

[0015] The beneficial effects of this utility model are: The present invention proposes an easy-to-manufacture inverted S-shaped anti-glare panel suitable for strong wind areas. The main body of the polymer phosphogypsum anti-glare panel is prepared using the patented technology of the formula and preparation method of polymer / phosphogypsum alloy flame-retardant cable tray, publication number 114752160A. The preparation method is simple, and it has strong tensile strength, aging resistance, corrosion resistance, water resistance, oil resistance, acid and alkali resistance, and mildew resistance. It also has good impact resistance under high or low temperature conditions, which can further enable the effective utilization and consumption of phosphogypsum waste. It is particularly suitable for use in desert and coastal areas with strong winds, and of course, it is also suitable for use in ordinary areas.

[0016] The base uses an elliptical base plate and two clamping plates with an inverted S-shaped cross section, which has good structural strength and meets the strength requirements of strong wind areas such as deserts and coastal areas. The complex structure is made of high-polymer material by injection molding, which is easy to manufacture.

[0017] The base plate is elliptical and has multiple non-penetrating cutouts on its bottom surface, which saves materials and reduces costs. The streamlined design of the elliptical base plate has no sharp corners and is unlikely to cause injury to people or other objects.

[0018] The side of the clamp plate facing away from the mounting groove is connected to the base plate with a first reinforcing rib, which can further improve the strength of the base.

[0019] Due to the excellent performance of the polymer phosphogypsum anti-glare board, it can be designed as a thin-walled structure with cavities. Multiple second reinforcing ribs are connected between the two sides in the width direction of the cavity, reducing material costs.

[0020] By placing two arc-shaped plate-shaped reinforcing ribs that can form a ring between the two plate-shaped second reinforcing ribs, the strength of the structure can be further enhanced.

The installation groove 8 matches the lower end of the polymer phosphogypsum anti-glare board body 2. The two clamping plates 7 are connected to the polymer phosphogypsum anti-glare board body 2 by fasteners. Specifically, each end of the two clamping plates 7 is provided with a corresponding first connecting hole 9. The polymer phosphogypsum anti-glare board body 2 is provided with a second connecting hole corresponding to the first connecting hole 9. The fasteners are M6 fastening bolts.
