[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0031] As Figures 1 to 8 The container composite floor structure shown in the figure comprises a top plate 1 and a bottom plate 2 arranged in parallel, and a sealing plate 3 connecting the two sides of the top plate 1 and the bottom plate 2 in the width direction, respectively, and a plurality of reinforcing ribs 5 connecting the top plate 1 and the bottom plate 2 vertically. The top plate 1, the bottom plate 2, the sealing plate 3 and the reinforcing ribs 5 are integrally formed by pultrusion process, and the material is carbon fiber reinforced composite material. It should be pointed out here that the width of a single floor can be 1160mm or 1141mm, and other widths can also be calculated according to actual conditions.

[0032] Among them, the reinforcing ribs 5 are uniformly distributed, and the reinforcing ribs 5 and the sealing plate 3 have the same extension direction.

[0033] The present application realizes the excellent performance of lightweight, high strength and durability by using carbon fiber reinforced composite material and integrally forming by pultrusion process. Compared with traditional wooden or steel floor, the structure is lighter in weight, significantly improves the transportation efficiency and reduces energy consumption, at the same time has good bending strength and impact resistance, can meet the demand of heavy load transportation; The uniformly distributed reinforcing ribs 5 design is consistent with the extension direction of the sealing plate 3, which optimizes the overall mechanical properties, effectively disperses the impact of external force, avoids damage caused by single point stress, and the corrosion resistance of the material makes it adapt to harsh transportation environment, prolongs the service life and reduces the maintenance cost.

[0034] As Figure 1 , Figure 2As shown, the top plate 1, the bottom plate 2 and the sealing plate 3 form a cavity 4 between them, and the reinforcing rib 5 is arranged inside the cavity 4, and a plurality of cavities 4 are evenly distributed. The lightweight of the floor structure is effectively realized, and the overall mechanical properties are enhanced, which can greatly reduce the weight of the floor under the premise of ensuring strength and rigidity, thereby improving transportation efficiency and reducing energy consumption. The reinforcing rib 5 is evenly distributed in the cavity 4, so that the structure has a more uniform stress effect when bearing heavy objects, avoiding damage caused by local stress concentration, and significantly improving the bending and impact resistance. It should be pointed out here that the number of cavities 4 can be designed according to actual needs. It should also be pointed out that the floor with the cavity 4, the thickness of the reinforcing rib 5 can be 4mm, and the thickness of the floor can be 20mm, and the thickness can also be increased or decreased according to actual different needs.

[0035] As shown in Figure 3 , Figure 4 The cavity 4 has a wood board 6 inside, and the top plate 1, the bottom plate 2, the sealing plate 3 and the reinforcing rib 5 are covered outside the wood board 6 and are pultruded together with the wood board 6. The design of arranging the wood board 6 inside the cavity 4 and covering the top plate 1, the bottom plate 2, the sealing plate 3 and the reinforcing rib 5 outside the wood board 6 and pultruding them together significantly improves the overall strength and rigidity of the floor structure. The wood board as the internal core material not only provides excellent load-bearing capacity, but also reduces the use of composite materials, thereby effectively reducing production costs. At the same time, the combination of wood board and external carbon fiber reinforced composite material forms a multi-layer structure, further improving the bending strength and impact resistance of the floor. The integrated pultrusion process ensures the close combination between the wood board and the composite material, avoids the loosening or falling problems that may occur in traditional splicing, enhances the structural stability, and prolongs the service life of the floor. It should be pointed out here that the floor with the wood board 6 can have a reinforcing rib 5 in the middle, which can be 2mm, and other thicknesses can also be set according to different needs. It should also be pointed out that the thickness of the floor with the wood board 6 can be 20mm, and other thicknesses can also be used according to actual needs. It should also be pointed out that the floor with the wood board 6 can be integrally formed with a single wood board, and then a fabric can be wrapped outside the whole, or the wood boards can be integrally formed directly.

[0036] When the floor is installed in the container, the container has a mounting strip, so that the floor and the mounting strip fit together, as shown in Figure 2As shown, the bottom plate 2 connected with the sealing plate 3 also has a mounting portion 31, the mounting portion 31 includes a first bending portion 31a close to the direction of the top plate 1, a mounting plate 31b connected with the first bending portion 31a and parallel to the top plate 1, and a second bending portion 31c connected between the mounting plate 31b and the sealing plate 3. The connection strength of the bottom plate 2 and the sealing plate 3 is enhanced, the external force is effectively dispersed and resisted, the connection part is prevented from being damaged due to stress concentration, the mounting plate 31b parallel to the top plate 1 provides a stable mounting surface for subsequent assembly, the precise connection with other structural members is facilitated, the installation efficiency and precision are improved, the anti-deformation ability is further improved by the double-bending structure, the stability and durability of the connection part in long-term use are ensured, and the high-strength requirement in complex transportation environment is met.

[0037] In some embodiments of the present application, as shown in Figure 5 、 Figure 6 The top plate 1 is attached with the bottom plate 2, and the reinforcing rib 5 extends away from the top plate 1. The reinforcing rib 5 extends away from the top plate 1, which not only increases the load-bearing capacity of the floor, but also effectively improves the bending strength and impact resistance of the structure. This layout maximizes the supporting effect of the reinforcing rib 5, while reducing the direct pressure on the top plate 1, avoiding damage caused by stress concentration.

[0038] According to the shape of the floor in the above, in order to make the floor have higher strength, as shown in Figure 6 The reinforcing rib 5 is T-shaped, including a reinforcing rod 51 connected with the bottom plate 2, and a reinforcing portion 52 away from one end of the bottom plate 2 and parallel to the top plate 1. The reinforcing portion 52 can significantly enhance the bending strength and overall stability of the floor structure, the vertical supporting effect of the reinforcing rod 51 effectively disperses the vertical stress of the floor when bearing heavy objects, and the parallel design of the reinforcing portion 52 and the top plate 1 further uniformly distributes external force, avoiding damage to the structure caused by stress concentration. The T-shaped structure has high torsional performance, ensures that the floor remains stable in shape in complex transportation environment, and improves impact resistance.

[0039] In order to make the bottom plate 2 of the above-mentioned top plate 1 and bottom plate 2 fit when installed in the container, the floor is more fitted in the container, and the sealing plate 3 further has a supporting rib 5653 extending in the same direction as the reinforcing rib 5, the supporting rib 5653 is L-shaped, including a supporting rod 53a connected with the sealing plate 3, and a supporting plate 53b connected with the supporting rod 53a and parallel to the top plate 1, and the length of the supporting rib 5653 is shorter than that of the reinforcing rib 5. By increasing the supporting structure of the sealing plate 3, the rigidity and bending strength of the sealing plate 3 are effectively improved, the stability of the overall floor structure is enhanced, the L-shaped supporting rib 5653 can disperse the stress of the sealing plate 3 and reduce the influence of stress concentration on the connecting part, avoid damage or deformation caused by long-term use, and the design that the length of the supporting rib 5653 is shorter than that of the reinforcing rib 5 can provide additional support while avoiding interference with the spatial layout and function of the reinforcing rib 5, and the coordination and bearing performance of the structure are optimized.

[0040] In some embodiments of the present application, as shown in Figure 7 , Figure 8 The reinforcing rib 5 includes a bearing part 54 fitted with the bottom plate 2, and a supporting part 55 connected with the bearing part 54, and the width of the bearing part 54 is greater than that of the supporting part 55. The width of the bearing part 54 is increased to be closely fitted with the bottom plate 2, effectively dispersing the vertical pressure of the floor under heavy load conditions, reducing local stress concentration, and prolonging the service life of the floor. The design that the width of the supporting part 55 is smaller can meet the structural support requirements while reducing the amount of material used, optimizing the overall weight distribution, and further achieving the lightweight goal. It should be pointed out here that the floor with the top plate 1 and the bottom plate 2 fitted can have a thickness of 10mm, and the number of reinforcing ribs 5 can also be increased or decreased according to actual conditions.

[0041] As shown in Figure 8 The sealing plate 3 further has a supporting rib 5653 with the same shape as the reinforcing rib 5, and the thickness of the supporting rib 5653 is less than that of the reinforcing rib 5. The design that the sealing plate 3 is provided with the supporting rib 5653 with the same shape as the reinforcing rib 5, and the thickness of the supporting rib 5653 is less than that of the reinforcing rib 5, effectively enhances the rigidity and deformation resistance of the sealing plate 3, and reduces the amount of material used by reducing the thickness of the supporting rib 5653, thereby achieving lightweight and cost optimization. The supporting rib 5653 has the same shape as the reinforcing rib 5, ensuring the coordination of the structural design, so that the supporting rib 5653 can disperse the stress in cooperation with the reinforcing rib 5, further improving the stability and bearing performance of the overall floor.

[0042] In some embodiments of the present application, the carbon fiber reinforced composite material is made of carbon fiber yarn, fabric and felt. The carbon fiber yarn, fabric and felt are combined to have excellent mechanical properties and durability. The carbon fiber yarn provides high strength and high rigidity, enhancing the load-carrying capacity of the material; the carbon fiber fabric ensures the overall uniformity and tensile properties of the material; the felt material further improves the impact resistance and fatigue resistance of the composite material. This composite design ensures the strength and rigidity of the material while achieving the lightweight goal, significantly reducing the self-weight of the floor and improving the transportation efficiency.
