Description

Technical Field

[0001] This utility model relates to a technical field, specifically a field. Background Technology

[0002] In cold storage facilities such as food cold storage, medical cold storage, and industrial low-temperature storage facilities, the flooring not only needs to have good load-bearing and wear resistance, but also must take into account functions such as preventing thermal bridges and condensate drainage. Existing cold storage flooring structures typically consist of an insulation layer plus a hard surface slab. However, due to the lack of an integrated independent drainage system, condensate easily accumulates on the surface, leading to icing, slipperiness, and accelerated floor damage. Furthermore, traditional insulation layers are prone to localized indentation under dynamic loads, compromising thermal insulation effectiveness. Therefore, there is an urgent need for a specialized cold storage flooring system that features optimized structure, integrated functions, and convenient construction to improve safety and extend the overall lifespan of the building.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Please see Figures 1 to 5 As shown, this utility model provides a cold storage color steel plate floor structure that integrates drainage function and thermal insulation, including a bottom support plate, a sandwich insulation layer, a drainage channel groove, a silicone insulation layer and a pressure-resistant cover plate. The structures are stacked sequentially from bottom to top, forming an integrated floor system with drainage, thermal insulation and pressure-resistant support functions.

[0025] The bottom support plate, located at the very bottom of the entire structure, can be made of hot-dip galvanized steel sheet or high-strength precast concrete slab, preferably 8–12 mm thick, to ensure good foundation load-bearing capacity of the ground structure. The support plate surface is treated with anti-corrosion coating, providing excellent durability and adaptability to the high humidity and low temperature environment required inside the cold storage. Several positioning holes or guide grooves are pre-drilled on the support plate according to the drainage layout for subsequent installation and positioning of the drainage channel grooves.

[0026] The sandwich insulation layer is laid on top of the bottom support plate to isolate heat exchange between the interior of the cold storage and the ground, preventing condensation and frost formation. The insulation layer is preferably made of high-density polyurethane foam board, XPS extruded board, or rock wool board with a closed-cell rate greater than 95%, and a thermal conductivity of less than or equal to 0.025 W / (m·K), providing excellent thermal insulation performance. The insulation layer thickness is determined according to the temperature zones of the cold storage, generally ranging from 50 to 100 mm to ensure the overall energy efficiency of the cold storage. The insulation layer can be bonded to the bottom plate using specialized structural adhesive, and positioning pins can be used if necessary to prevent displacement or floating caused by temperature differences.

[0027] The drainage channel is embedded inside the sandwich insulation layer, forming a continuous drainage system through pre-designed groove paths. The drainage channel is made of high-density polyethylene (HDPE) or modified polypropylene (PP), with a smooth inner surface and low coefficient of friction, effectively reducing condensate flow resistance. The channel width is preferably 80–120 mm, and the depth is preferably 50–80 mm. Its cross-section can be designed as rectangular or arc-shaped to enhance drainage efficiency. Each section of the drainage channel is sloped according to the overall layout of the cold storage floor, preferably 1%–2%, guiding condensate along the channel to the main drainage pipe outlet through natural gravity. To prevent impurities from accumulating and clogging, a gentle slope transition section can be provided inside the drainage channel to reduce water accumulation in dead corners. Inspection ports are also provided at appropriate locations for easy cleaning and maintenance.

[0028] The silicone insulation layer is laid on top of the drainage channel and the sandwich insulation layer. It is made of a one-piece molded high-elasticity silicone sheet with a thickness ranging from 5 to 10 mm. The silicone insulation layer not only provides excellent thermal insulation but also, due to its flexible cushioning properties, can absorb the impact of dynamic ground loads, extending the service life of the upper cover and internal structure. The silicone material has excellent low-temperature resistance, maintaining elastic stability within a temperature range of -40℃ to +80℃, effectively preventing micro-cracks or structural loosening caused by thermal expansion and contraction.

[0029] The pressure-resistant cover plate is installed above the silicone insulation layer, serving as the outermost load-bearing surface of the entire flooring system. The cover plate is made of 2-4mm thick stainless steel sheet with an anti-slip treatment; brushed, orange peel, or diamond-patterned finishes are available to increase the floor's friction coefficient and prevent slippage by personnel and forklifts. The cover plate is secured to the silicone insulation layer surface with structural adhesive or special metal clips, ensuring it will not shift or flip up during use and facilitating future disassembly and replacement.

[0030] To facilitate the maintenance of the ground drainage system, this utility model is designed with several detachable inspection ports above the drainage channel. The inspection ports are covered by small stainless steel covers and fixed with screws or buckles. Users can open the inspection ports periodically as needed to clean and maintain the inside of the drainage channel to ensure the unobstructed flow of the drainage system.

[0031] This utility model, through its scientific layout, highly integrates drainage, thermal insulation, and ground load-bearing functions into one unit. It not only improves the performance of the cold storage floor and avoids problems such as cold bridging, frost, and water accumulation that are common in traditional cold storage floors, but also greatly facilitates later inspection and maintenance. The overall structure is lightweight and high-strength, and easy to construct, possessing significant practical value and broad application prospects.

[0032] 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 preferred examples and are not intended to limit the utility model.
