Description

Technical Field

[0001] This invention relates to the field of refrigerated containers, and more particularly to a non-metallic refrigerated container floor. Background Technology

[0002] Currently used refrigerated container T-shaped floors are all made of aluminum profiles. Aluminum floors are prone to oxidation and corrosion in high-humidity environments and seawater contact, and may undergo electrolytic reactions when in contact with other metals. Aluminum has a high thermal conductivity, which easily forms "cold bridges," causing rapid loss of cold air inside the container and increasing energy consumption during transportation. Aluminum floors are also prone to metal-to-metal friction during forklift operations and cargo handling, posing safety hazards. Summary of the Invention

[0003] Purpose of the invention: To address the shortcomings and defects of existing technologies, this invention provides a non-metallic refrigerated container floor that reduces corrosion, minimizes cold bridging effects, lowers energy consumption during transportation, and avoids safety hazards caused by metal friction.

[0004] Technical solution: The present invention provides a non-metallic refrigerated container floor, characterized in that: it includes a T-shaped floor, which comprises a T-shaped central portion, a T-shaped wing portion, and a T-shaped side portion stacked sequentially; the T-shaped floor, together with polyurethane insulation material, a floor center support block, a bottom corrugated plate, and bottom side beams, forms the container's underframe structure; the T-shaped wing portion and the composite material anti-collision plate are connected by rivets and sealed with adhesive.

[0005] The two T-side portions are bonded together with a serrated surface and sealant to form a combined structure.

[0006] The T-side portion includes filling yarn, fabric lay-up, and resin.

[0007] The T-shaped floor is a T-shaped floor, and several T-shaped floors are arranged continuously or at intervals.

[0008] The T-shaped flooring, which is spaced apart, includes a single T-section, a hidden adhesive, a serrated surface bonding assembly, and an adhesive.

[0009] The bottom of the single-T portion is fixed by a serrated surface adhesive assembly, which includes a hidden adhesive and a colloid.

[0010] The container in question is a refrigerated container.

[0011] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: The present invention is mainly made of composite materials, mainly using a combination of fabric, yarn and resin. Multiple layers of fabric are pressed in regular areas, yarn is used to fill the triangular area of ​​the T-shaped head, and resin is used for solidification and molding.

[0012] This invention eliminates corrosion and electrolytic losses: Aluminum flooring is prone to oxidation and corrosion in high-humidity, seawater-contact environments, and may undergo electrolytic reactions upon contact with other metals. Non-metallic T-shaped flooring is acid and alkali resistant, poses no oxidation risk, and is suitable for ocean-going and high-humidity cold chain scenarios. It also blocks cold bridges, reducing energy consumption: Aluminum has a high thermal conductivity, easily forming "cold bridges" that cause rapid loss of cold air inside the container. Non-metallic materials have low thermal conductivity, and the T-shaped structure further optimizes the insulation path, reducing the load on the refrigeration system. Lightweight construction improves loading efficiency: Non-metallic materials (such as FRP and polymer composites) are 20%-40% lighter than aluminum. Reduced floor weight directly increases the effective cargo capacity of the container or reduces fuel consumption during transportation. Finally, it reduces maintenance and replacement costs: Aluminum flooring is easily scratched and deformed, and once corroded, it cannot be repaired and requires complete replacement. Non-metallic T-shaped flooring is wear-resistant and impact-resistant, has a longer service life, and lower subsequent maintenance costs. Avoiding the safety hazards of metal friction: Aluminum flooring is prone to generating metal friction sparks during forklift operations and cargo handling, while non-metallic materials do not pose this risk and are suitable for special cold chain transportation needs such as flammable and explosive materials.

Detailed Implementation

[0017] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] The non-metallic refrigerated container floor of the present invention includes a T-shaped floor, which comprises a T-shaped central portion 100, a T-shaped wing portion 200 and a T-shaped side portion 300 stacked sequentially. The T-shaped floor, together with polyurethane insulation material 500, floor center support block 600, bottom corrugated plate 800 and bottom side beam 900, forms the underframe structure of the container through a sandwich foaming process. The T-shaped wing portion 200 and the composite material anti-collision plate 400 are connected by rivets and sealed with adhesive.

[0019] The two T-side portions 300 are combined into a single structure 700 by a serrated surface 304 and a sealant bonding assembly 305. The T-side portion 300 includes filling yarn 301, fabric lay-up 302, and resin 303.

[0020] The T-shaped floor is a T-floor 010, with several T-floors 010 arranged continuously or intermittently. An intermittently arranged T-floor 010 includes a single T-section 011, a concealed adhesive 012, a serrated surface adhesive assembly 013, and an adhesive 020. The bottom of the single T-section 011 is fixed by the serrated surface adhesive assembly 013, which includes the concealed adhesive 012 and the adhesive 020. The container is a refrigerated container.

[0021] This invention is mainly made of composite materials, primarily using a combination of fabric, yarn, and resin. Multiple layers of fabric are pressed in regular areas, yarn is used to fill the triangular area of ​​the T-shaped head, and resin is used for solidification and molding.

[0022] This invention is not limited to a single T-structure. As the process matures, multiple T-structures (such as 5T, 7T, 11T, 33T, etc.) can be integrally molded, thereby eliminating the need for structural adhesives or rivets for connection.

[0023] This invention eliminates corrosion and electrolytic losses: Aluminum flooring is prone to oxidation and corrosion in high-humidity, seawater-contact environments, and may undergo electrolytic reactions upon contact with other metals. Non-metallic T-shaped flooring is acid and alkali resistant, poses no oxidation risk, and is suitable for ocean-going and high-humidity cold chain scenarios. It also blocks cold bridges, reducing energy consumption: Aluminum has a high thermal conductivity, easily forming "cold bridges" that cause rapid loss of cold air inside the container. Non-metallic materials have low thermal conductivity, and the T-shaped structure further optimizes the insulation path, reducing the load on the refrigeration system. Lightweight construction improves loading efficiency: Non-metallic materials (such as FRP and polymer composites) are 20%-40% lighter than aluminum. Reduced floor weight directly increases the effective cargo capacity of the container or reduces fuel consumption during transportation. Finally, it reduces maintenance and replacement costs: Aluminum flooring is easily scratched and deformed, and once corroded, it cannot be repaired and requires complete replacement. Non-metallic T-shaped flooring is wear-resistant and impact-resistant, has a longer service life, and lower subsequent maintenance costs. Avoiding the safety hazards of metal friction: Aluminum flooring is prone to generating metal friction sparks during forklift operations and cargo handling, while non-metallic materials do not pose this risk and are suitable for special cold chain transportation needs such as flammable and explosive materials.
