Description

Technical Field

[0001] This utility model relates to a water tank assembly template, and more specifically, to a multi-layered corrosion-resistant ultra-high strength water tank template and a prefabricated water tank. Background Technology

[0002] Prefabricated water tanks are water supply and drainage equipment assembled from water tank templates. They are widely used in fire protection systems to provide emergency water sources, as well as for storing domestic and drinking water.

[0003] Water tank formwork (also known as "molded plate") is the main pressure-bearing component of prefabricated water tanks. It is typically made of stainless steel, but with the rising price of stainless steel, the manufacturing cost of traditional stainless steel water tanks is becoming increasingly expensive. Chinese Patent Publication No. CN216068998U discloses a "Novel Carbon Fiber Reinforced Composite Water Tank Formwork" (publication date: March 18, 2022). This water tank formwork includes a molded plate (made of carbon steel, stainless steel, or fiberglass) formed by molding and stretching a single sheet. An inner layer plate (made of food-grade stainless steel or fiberglass) is provided on the water-contact side of the molded plate to cover the water-contact surface. A carbon fiber reinforcing sheet is placed between the molded plate and the inner layer plate. The molded plate, carbon fiber reinforcing sheet, and inner layer plate are bonded together as a single unit. This water tank formwork significantly improves the tensile and compressive strength of the water tank formwork while reducing the amount of metal materials used. However, fiberglass has poor corrosion resistance and durability. The three-layer structure is bonded together with adhesive, and the manufacturing process is relatively complex, so the overall manufacturing cost of the water tank template is still high.

[0004] Chinese Patent Publication No. CN222252444U discloses "A Novel Corrosion-Resistant Water Tank Module" (publication date: December 27, 2024). From the outside in, it comprises a water tank bottom plate, a hot-dip galvanized layer, a plastic-coated layer, and a reinforcing layer. The bottom plate has a hot-dip galvanized layer, which is further covered by a plastic-coated layer. The reinforcing layer is a raised structure extending towards the outer edge of the frame. It utilizes the hot-dip galvanized and plastic-coated layers to achieve corrosion resistance. However, the outer side of the bottom plate lacks an anti-corrosion structure. When used in outdoor and underground water tanks, it cannot solve the problem of corrosion on the outer side of the tank. Furthermore, it primarily relies on the bottom plate for pressure bearing, resulting in poor pressure-bearing capacity.

[0005] Given the aforementioned shortcomings of existing water tank formwork in terms of corrosion resistance and pressure resistance, it is necessary to develop an enhanced water tank formwork with dual anti-corrosion functions. Summary of the Invention

[0006] 1. Technical problem to be solved by the utility model

[0007] The purpose of this utility model is to overcome the aforementioned shortcomings of existing water tank templates and provide a multi-layered, high-strength, corrosion-resistant water tank template and a prefabricated water tank. Using the technical solution of this utility model, the template body is molded from double-sided coated plates, with an inner plastic anti-corrosion layer laminated on the inner side and a fiber reinforcement layer and an outer plastic anti-corrosion layer laminated sequentially on the outer side. The zinc plating layer of the double-sided coated plates and the inner and outer plastic anti-corrosion layers achieve corrosion resistance for the water tank template, providing multiple anti-corrosion functions, greatly improving the corrosion resistance and service life of the water tank template. Furthermore, the composite structure of the double-sided coated plates and fiber reinforcement layers provides pressure resistance, improving the strength and compressive strength of the water tank template. At the same time, compared with existing water tank templates, the double-sided coated plates and plastic anti-corrosion layers have lower material costs and simpler manufacturing processes, effectively reducing the manufacturing cost of the water tank template and the prefabricated water tank, resulting in significant economic benefits.

[0035] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0036] [Example]

[0037] Combination Figures 1 to 3As shown, this embodiment of a multi-layered anti-corrosion ultra-high strength water tank template includes a template body molded from a double-sided coated plate 1a. The double-sided coated plate 1a is a steel plate with a hot-dip galvanized or electroplated anti-corrosion metal material on its surface. Compared with stainless steel plates, the cost of the double-sided coated plate 1a is much lower than that of stainless steel plates, and its surface coating can improve the corrosion resistance of the steel plate. Figure 2 As shown, the side of the template body located inside the water tank is called the "inner" side, and the side located outside the water tank is called the "outer" side. The inner side of the template body is the wading surface. Figure 3 As shown, in this embodiment, the inner water-contact surface of the template body is composited with an inner plastic anti-corrosion layer 1b, and the outer side of the template body is sequentially composited with a fiber reinforcement layer 1c and an outer plastic anti-corrosion layer 1d. The fiber reinforcement layer 1c can improve the strength of the double-sided coated plate 1a, compensate for its strength difference with stainless steel, and improve the pressure-bearing capacity of the water tank template. The inner plastic anti-corrosion layer 1b and the outer plastic anti-corrosion layer 1d can further improve the corrosion resistance of the water tank template and extend its service life. With the addition of the anti-corrosion coating, the water tank template has a six-layer composite structure from the inside out: inner plastic anti-corrosion layer 1b -- anti-corrosion coating -- steel plate -- anti-corrosion coating -- fiber reinforcement layer 1c -- outer plastic anti-corrosion layer 1d. Among them, the steel plate has two anti-corrosion layers (anti-corrosion coating and plastic anti-corrosion layer) on both the inside and outside, realizing multiple anti-corrosion of the water tank template.

[0038] Therefore, compared with existing water tank templates, the multi-corrosion-resistant ultra-high strength water tank template of this embodiment utilizes the galvanized layer of the double-sided coated plate and the inner and outer plastic anti-corrosion layers to achieve corrosion resistance, providing multiple anti-corrosion functions, greatly improving the corrosion resistance and service life of the water tank template. Furthermore, the composite structure of the double-sided coated plate and fiber reinforcement layer for pressure bearing enhances the strength and compressive strength of the water tank template. At the same time, compared with existing water tank templates, the double-sided coated plate and plastic anti-corrosion layer have lower material costs and simpler manufacturing processes, effectively reducing the manufacturing cost of water tank templates and prefabricated water tanks, resulting in significant economic benefits.

[0039] Specifically, in this embodiment, the inner plastic anti-corrosion layer 1b is formed by molding a plastic film together with the inner surface of the double-sided coated plate 1a. During manufacturing, the plastic film and the double-sided coated plate 1a are laid together on a molding machine and then molded together at high temperature, so that the plastic film is bonded to the inner surface of the template body. To improve the bonding strength between the plastic film and the double-sided coated plate 1a, an adhesive material can be pre-applied to the inner surface of the double-sided coated plate 1a. Using the above-mentioned composite process, the inner plastic anti-corrosion layer 1b provides good coverage of the double-sided coated plate 1a and has a smooth surface, making it easy to clean the inside of the water tank. Furthermore, the material of the inner plastic anti-corrosion layer 1b is PE (polyethylene), which has good chemical stability, strong corrosion resistance, is non-toxic and harmless, and will not pollute the water in the water tank.

[0040] In this embodiment, the fiber reinforcement layer 1c is provided in two or more layers on the outer surface of the double-sided coated plate 1a. Preferably, the fiber reinforcement layer 1c is a carbon fiber cloth adhered to the outer surface of the double-sided coated plate 1a, which has advantages such as high strength, low density, and thinness. It effectively strengthens the compressive strength of the double-sided coated plate 1a and has strong durability. Simultaneously, the carbon fiber cloth also provides some corrosion resistance. In specific implementation, multiple layers of carbon fiber cloth can be adhered to the outer surface of the double-sided coated plate 1a, with each layer laid at a certain angle to provide strength reinforcement at multiple stress angles. The fiber reinforcement layer 1c can be installed after the template body is molded. The outer plastic anti-corrosion layer 1d is a dip-coated or powder-coated layer laminated to the outer surface of the fiber reinforcement layer 1c. Both dip-coating and powder coating are mature technologies. Using dip-coating or powder coating to form the outer plastic anti-corrosion layer is simple and convenient to manufacture, and ensures strong and reliable adhesion. On the one hand, it provides external anti-corrosion function; on the other hand, it protects the fiber reinforcement layer 1c, further improving the durability of the water tank template and the water tank. The aforementioned outer plastic anti-corrosion layer 1d is also made of PE (polyethylene), laminated to the outside of the water tank template using dip-coating or powder coating, providing external anti-corrosion for the water tank with minimal environmental pollution.

[0041] The coating of the aforementioned double-sided coated plate 1a is a zinc-aluminum-magnesium coating. The various metal elements in the zinc-aluminum-magnesium alloy coating work together to reduce the consumption rate of the surface coating of the coated steel plate, and have anti-corrosion properties and an ultra-long service life. Its anti-corrosion performance is better than that of galvanized steel plate.

[0042] Similar to existing water tank template structures, the template body in this embodiment includes a panel 1. The panel 1 has integrally formed beveled flanges 2 around its four sides, and integrally formed vertical flanges 3 around the beveled flanges 2. The beveled flanges 2 are at a 45° angle to the panel 1 and can serve as corner modules for 90° corner assembly of adjacent water tank templates. The vertical flanges 3 are at a 90° angle to the panel 1 and can serve as planar modules for splicing to form the water tank surface. When used as a planar module, the vertical flanges 3 can have several connecting holes; when used as corner modules, the corresponding beveled flanges 2 can have several connecting holes. Additionally, the panel 1 is also molded with a reinforcing structure. The inner plastic anti-corrosion layer 1b extends from the panel 1 to either the beveled flanges 2 or the vertical flanges 3. That is, the inner plastic anti-corrosion layer 1b can cover only the inner water-contacting surface of the water tank template or completely cover the inner surface of the water tank template. Figure 1 As shown, the above-mentioned reinforcing structure includes an arc-shaped concave surface 1-1 on the plate surface 1, a cross-shaped rib 1-2 inside the arc-shaped concave surface 1-1, and a central concave surface 1-3 at the intersection of the cross-shaped rib 1-2, which further improves the compressive strength of the water tank template. Figure 1 The image shown is a square water tank template. Figure 4 and Figure 5 The diagram shows two specifications of rectangular water tank templates. The reinforcing structures on the water tank template can be arranged according to its length. When multiple reinforcing structures are provided, adjacent reinforcing structures can be separated by molded rib structures.

[0043] This embodiment also relates to a prefabricated water tank. This prefabricated water tank is assembled from several of the aforementioned multi-layered anti-corrosion ultra-high strength water tank templates. The resulting water tank exhibits strong corrosion resistance and pressure resistance, is durable, and has a relatively lower manufacturing cost.

[0044] As for the other structures of the prefabricated water tank, they are similar to existing technologies, so they will not be described in detail here.

[0045] This utility model discloses a multi-layered anti-corrosion ultra-high strength water tank template and an assembled water tank. The template body is molded from double-sided coated plates, with an inner plastic anti-corrosion layer laminated on the inner side and a fiber reinforcement layer and an outer plastic anti-corrosion layer laminated on the outer side. The galvanized layer of the double-sided coated plates and the inner and outer plastic anti-corrosion layers achieve corrosion protection for the water tank template, providing multiple anti-corrosion functions and significantly improving its corrosion resistance and service life. Furthermore, the composite structure of the double-sided coated plates and fiber reinforcement layers enhances the pressure resistance and compressive strength of the water tank template. Compared with existing water tank templates, the double-sided coated plates and plastic anti-corrosion layers have lower material costs and simpler manufacturing processes, effectively reducing the manufacturing cost of the water tank template and assembled water tank, resulting in significant economic benefits.

[0046] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
