Technical Field
[0001] The utility model relates to the technical field of plastic grilles, in particular to a reinforced plastic grille. Background Art
[0002] In the rapidly evolving field of modern engineering, particularly in civil engineering, transportation infrastructure construction, agricultural irrigation systems, and the reinforcement and repair of building structures, plastic grating serves as a crucial reinforcement material. Improving its performance and quality is directly related to the safety, durability, and economic benefits of engineering projects. While traditional plastic gratings, such as unidirectional or bidirectional tension gratings, can be effective in certain specific applications, their design limitations make them inadequate in complex and changing stress environments.
[0003] Specifically, traditional gratings perform adequately when only considering single or bidirectional forces. However, in actual engineering, structures often need to withstand the combined effects of multiple forces, including tension, shear, bending, and compression from multiple directions. This complex stress state requires grating materials to possess higher strength, improved toughness, and enhanced deformation resistance to ensure the overall stability and long-term performance of the engineering structure. However, the shortcomings of traditional gratings in these aspects often lead to their susceptibility to fracture, deformation, or failure in complex stress environments, posing potential safety risks and economic losses to engineering projects.
[0004] Therefore, the development of a reinforced plastic grating that can adapt to complex stress environments, have higher load-bearing capacity and stronger deformation resistance has become an urgent need in the industry. Utility Model Content
[0005] To address these issues, the present invention provides a reinforced plastic grating. This grating is designed to consist of a rectangular unit, a first annular unit, and a second annular unit. Diagonal reinforcement ribs are provided within the rectangular units, and reinforcement nodes are located at key points. This grating effectively disperses and absorbs stress in multiple directions, including horizontal, vertical, and diagonal directions, significantly improving its load-bearing capacity and deformation resistance. This solves the problem of traditional gratings being susceptible to failure in complex stress environments and meets the demand for high-performance grating materials in modern engineering.
[0006] The technical solution of the utility model is as follows:
[0007] A reinforced plastic grille is formed by a plurality of component units arranged and connected in sequence in the transverse and longitudinal directions. The component units include a rectangular unit, a first annular unit, and a second annular unit. The transverse and longitudinal top ends of the first annular unit respectively coincide with the transverse and longitudinal sides of the rectangular unit. The second annular unit is smaller than the first annular unit and is arranged within the rectangular unit. Reinforcing ribs are arranged on the diagonals of the rectangular unit. Reinforcement nodes are provided at the intersections of the reinforcing ribs and at the intersections of the reinforcing ribs with the first and second annular units.
[0008] Optionally, the transverse sides and the longitudinal sides of the rectangular unit are equal.
[0009] The first annular unit and the second annular unit are circular ring-shaped. The diameter of the second annular unit is smaller than the diameter of the first annular unit. The outer diameter of the first annular unit is equal to the side length of the rectangular unit.
[0010] The centers of the first annular unit and the second annular unit are concentric and are both concentric with the center of the rectangular unit.
[0011] Optionally, the transverse sides and longitudinal sides of the rectangular unit are not equal.
[0012] The first annular unit and the second annular unit are elliptical annular shapes.
[0013] The major axis and minor axis of the first annular unit and the second annular unit are respectively on the same straight line.
[0014] The long axis of the first annular unit is equal to the long side of the rectangular unit, and the short axis of the first annular unit is equal to the short side of the rectangular unit.
[0015] The reinforced plastic grille is an injection molded part.

[0028] like Figure 1As shown, the reinforced plastic grid is composed of a number of carefully designed component units 1 arranged in sequence and tightly connected in the horizontal and vertical directions, forming a grid system with strong integrity and stable structure.
[0029] like Figure 2 As shown, each component unit 1 includes three core parts: a rectangular unit 11 , a first annular unit 12 and a second annular unit 13 .
[0030] Rectangular unit 11: Serving as the basic framework of the grille, the horizontal and vertical sides of rectangular unit 11 are designed with various specifications to suit different project requirements. This technical solution emphasizes that when the horizontal and vertical sides of rectangular unit 11 are equal, the resulting square unit can provide balanced mechanical properties and an aesthetically pleasing appearance. When the sides are unequal, the aspect ratio can be adjusted according to the specific application scenario to optimize the grille's mechanical performance.
[0031] First annular element 12: Fitted snugly around the rectangular element 11, its transverse and longitudinal tops coincide with the corresponding edges of the rectangular element 11, forming a solid protective perimeter. Its outer diameter is strictly equal to the side length of the rectangular element 11, ensuring a seamless connection between the two. The first annular element 12 not only strengthens the grille's edge strength but also, through its circular design, disperses stress concentration from the edges, improving the grille's overall durability.
[0032] Second Ring Unit 13: Compared to the first ring unit 12, the second ring unit 13 is smaller and cleverly embedded within the rectangular unit 11. This design further enriches the grid's hierarchical structure while providing additional support and reinforcement within the internal area. When the rectangular unit 11 is square, the second ring unit 13 is also circular; when the rectangular unit 11 is rectangular, the second ring unit 13 is adjusted to an elliptical ring to maintain geometric harmony with the rectangular unit 11.
[0033] To further enhance the grid's load-bearing capacity and deformation resistance, this technical solution incorporates reinforcing ribs 14 along the diagonals of the rectangular units 11. These ribs 14 extend diagonally, forming a stable cross-bracing structure that effectively resists diagonal tensile and shear forces. Furthermore, reinforced nodes 15 are specifically designed at the intersections of the ribs 14 and at their intersections with the first and second annular units 12, 13. These nodes, through optimized design and material reinforcement, ensure stability and reliability at key stress-bearing points.
[0034] This technical solution utilizes high-performance engineering plastics as the base material, which exhibits excellent mechanical properties, weather resistance, corrosion resistance, and processing properties. Specifically, high-strength, high-modulus thermoplastics such as polypropylene (PP), polyethylene (PE), and nylon (PA) can be used. These materials not only meet the requirements of the grille's use in various engineering environments, but also offer excellent recyclability and environmental friendliness.
[0035] Reinforced plastic grilles are produced using an injection molding process. This process offers advantages such as high production efficiency, high dimensional accuracy, and excellent surface quality. During the injection molding process, molten plastic is injected into a pre-designed mold. High pressure and cooling solidify the plastic into shape. The mold design must precisely match the structural dimensions and shape requirements of the grille to ensure the accuracy and consistency of the final product.
[0036] The mold is a core piece of equipment in the injection molding process. The mold design for this technical solution fully considers the grille's complex structure and precision requirements. Advanced CAD / CAM technology is used for mold design, with 3D modeling and simulation analysis used to optimize the mold structure. High-precision machining equipment and advanced manufacturing techniques are also employed to manufacture the mold, ensuring its accuracy and durability.
[0037] During the production process, we strictly control the quality of raw materials, injection temperature, pressure, time and other process parameters to ensure the performance and quality of the grille. We monitor and evaluate key links in the production process through online testing and quality control systems. We also establish a comprehensive traceability mechanism and product file management system to ensure the traceability and quality of each batch of products.
[0038] To enhance the anti-slip performance and aesthetics of reinforced plastic grating, this technical solution incorporates anti-slip textures on the upper and lower surfaces of the grating. These textures are molded directly into the grating surface, resulting in a strong, wear-resistant structure. The design of the anti-slip textures must take into account the grating's operating environment and stress characteristics to ensure effective anti-slip performance under varying operating conditions.
[0039] In addition, the grille can be further surface treated according to customer requirements, such as spraying, electroplating, etc., to improve its corrosion resistance, wear resistance and aesthetics. These surface treatment processes must comply with relevant standards and regulations to ensure the quality of the treatment and environmental friendliness.
