Description

Technical Field

[0001] This utility model relates to the field of water storage equipment technology, specifically to a prefabricated water tank without bracing, columns, or welding. Background Technology

[0002] Prefabricated stainless steel water tanks, assembled from modules, typically require on-site welding by professionals. This not only demands high skill from construction workers and results in low construction efficiency, but also leads to frequent corrosion at the welded areas, affecting water quality and failing to meet hygiene standards for water-related products. Furthermore, the tanks have a short lifespan. Traditionally, stainless steel water tanks use internal support components formed by braces and columns to meet the pressure requirements of the tank's side panels and ensure the tank remains flat, stable, and free from deformation. The problems with this structure are: low welding efficiency and long assembly cycles; frequent corrosion at welded areas affecting water quality and failing to meet hygiene standards for water-related products; short lifespan; the braces and columns hinder cleaning; and the support components occupy significant internal space, increasing the difficulty and workload of internal equipment layout and making subsequent regular maintenance, cleaning, and replacement inconvenient. Therefore, this invention proposes a prefabricated water tank without braces, columns, or welding to solve the aforementioned technical problems. Summary of the Invention

[0003] The purpose of this invention is to overcome the defects in the existing technology and provide a prefabricated water tank without bracing, columns, or welding. A set of straight, folded edges on two adjacent side panels on the same side wall of the water tank are connected together by a clamping assembly, significantly improving the structural strength and pressure-bearing capacity of the side panel joints and effectively preventing water pressure deformation at the joints. The top beam assembly supports the top wall of the water tank, improving its load-bearing capacity. Simultaneously, the top beam assembly limits and tightens the upper ends of a set of side walls distributed at both ends, improving the overall structural strength of the prefabricated water tank without bracing, columns, or welding. The water tank has no internal bracing, columns, or other supporting components, truly achieving a prefabricated water tank design without bracing, columns, or welding. Furthermore, the entire structure requires no welding, resulting in a short assembly and construction cycle. It ensures that the water quality meets the hygiene standards for water-related products and has advantages such as high strength, strong pressure resistance, low manufacturing cost, convenient internal equipment layout, easy cleaning, and long service life.

[0004] To achieve the above objectives, the technical solution of this utility model is to design a prefabricated water tank without bracing, columns, or welding, comprising four side walls and a top wall. The four side walls are spliced ​​into a rectangular frame structure, and the top wall is fixed to the top of the rectangular frame structure. Each side wall is formed by sequentially connecting several side plates. The outer periphery of each side plate has a straight folded edge that folds outward from the water tank. A set of straight folded edges on two adjacent side plates on the same side wall are connected together by a clamping assembly. The system also includes several parallel and spaced top beam assemblies fixed to the lower side of the top wall. The two ends of each top beam assembly abut against the upper inner side of a set of side walls.

[0005] This utility model discloses a prefabricated water tank without bracing, columns, or welding. A set of straight, folded edges on two adjacent side panels of the same side wall are connected together by a clamping assembly, significantly improving the structural strength and pressure-bearing capacity of the side panel joints and effectively preventing water pressure deformation at the joints. The top beam assembly supports the top wall of the water tank, increasing its load-bearing capacity. Simultaneously, the top beam assembly limits and tightens the upper ends of a set of side walls distributed at both ends, further enhancing the overall structural strength of the prefabricated water tank. The tank interior lacks bracing, columns, and other supporting components, truly achieving a prefabricated water tank design without bracing, columns, or welds. Furthermore, the entire structure requires no welding, resulting in a short assembly period. It ensures that the water quality meets the hygiene standards for water-related products and offers advantages such as high strength, strong pressure resistance, low manufacturing cost, convenient internal equipment layout, easy cleaning, and long service life.

[0006] A preferred technical solution is that the clamping assembly includes two L-shaped reinforcing plates and several reinforcing horizontal plates. The vertical plates of the two L-shaped reinforcing plates are respectively clamped to both sides of a set of straight folded edges on two adjacent side plates located on the same side wall of the water tank. The vertical plates of the two L-shaped reinforcing plates and the clamped set of straight folded edges are fixedly connected together by bolt assemblies. The horizontal plates of the two L-shaped reinforcing plates extend away from the sides of the corresponding set of straight folded edges. The several reinforcing horizontal plates are spaced apart along the longitudinal direction and attached to the outer surfaces of the horizontal plates of the two L-shaped reinforcing plates. Both ends of the reinforcing horizontal plates are fixedly connected to the corresponding horizontal plates by bolt assemblies. The clamping assembly has a clever and reasonable structural design. The two L-shaped reinforcing plates have good compatibility with the clamped set of straight folded edges, thereby ensuring that the clamping assembly has good overall clamping stability for the clamped set of straight folded edges. Furthermore, the reinforcing horizontal plates further improve the long-term stability of the clamping force of the two L-shaped reinforcing plates on the clamped set of straight folded edges.

[0007] A further preferred technical solution is that the horizontal edge of the L-shaped reinforcing plate, facing away from the corresponding vertical plate two, is bent to form a vertical plate three extending towards the water tank side, and the length of the vertical plate three in the horizontal section is less than the length of the corresponding vertical plate two in the horizontal section. The vertical plate three improves the structural strength of the L-shaped reinforcing plate, thereby helping to further improve the long-term stability of the clamping force of the clamping assembly on the set of straight folded edges.

[0008] A further preferred technical solution is that the top wall of the water tank is horizontally spliced ​​together from several top plates. The outer periphery of both the side plates and the top plates is provided with oblique folded edges that extend outward from the water tank. The outer edge of the oblique folded edge is provided with a straight folded edge that extends outward and is perpendicular to the body of the side plate or the top plate. Two adjacent side plates located at the corner of the water tank are fixedly connected together by bolt assemblies that pass through the mounting holes on a set of opposite oblique folded edges. Two adjacent top plates on the top wall of the water tank are fixedly connected together by bolt assemblies that pass through the mounting holes on a set of opposite straight folded edges. The oblique folded edges located at the outer periphery of the top wall of the water tank are respectively fixedly connected to the oblique folded edges at the upper edge of the four side walls of the water tank by bolt assemblies that pass through the mounting holes on both. Two adjacent side plates on the same side wall of the water tank or two adjacent top plates on the top wall of the water tank form a V-shaped groove with an opening facing the inside of the water tank at the joint. The two adjacent top plates, the two adjacent side plates, and the top plate and the adjacent side plate are all fixedly connected together by bolt assemblies, which ensures convenient positioning and efficient assembly and fixing when splicing the rectangular frame, the water tank top wall, and the rectangular frame and the water tank top wall.

[0009] A further preferred technical solution includes a top beam assembly comprising a top rod, a bottom rod, and several vertical support rods. The top rod and bottom rod are flush at both ends and fixedly connected together by a set of connecting plates and bolt assemblies attached to both ends. Several vertical support rods are spaced apart between the top rod and bottom rod, with their upper ends fixedly connected to the top rod and their lower ends fixedly connected to the bottom rod by bolt assemblies. The top rod has two symmetrically arranged inclined top plates that gradually expand downwards and outwards to both sides. These two inclined top plates are inserted into a corresponding V-shaped groove at the joint of the water tank top wall, and are fixedly connected to the corresponding side walls of the V-shaped groove by bolt assemblies. The top beam assembly has a clever and reasonable structural design; the two inclined top plates at the top of the top rod are inserted and fixed into a corresponding V-shaped groove at the joint of the water tank top wall, ensuring good installation stability of the top beam assembly on the lower side of the water tank top wall.

[0010] A further preferred technical solution includes two vertical plates (I) fixed to the lower edges of the two inclined top plates on the top rod. The two inclined top plates and the two vertical plates (I) together form a downward-opening cavity (I). The bottom rod is an arc-shaped rod with its concave side facing upward, and it has an upward-opening cavity (II) inside. The upper end of the vertical support rod is inserted into the cavity (I) on the top rod and fixedly connected to the two vertical plates (I) by bolt assemblies. The lower end of the vertical support rod is inserted into the cavity (II) on the bottom rod and fixedly connected to the two side walls of the cavity (II) by bolt assemblies. The upper end of the vertical support rod is inserted into the cavity (I) of the top rod, and the lower end is inserted into the cavity (II) of the bottom rod, ensuring convenient positioning and installation of the vertical support rod between the top and bottom rods, while also ensuring good overall stability and high structural strength of the top beam assembly.

[0011] A further preferred technical solution includes having the lower ends of the four water tank sidewalls cast into the foundation; or, it further includes several water tank bottom plates horizontally spliced ​​together, with the bottom plates having the same structure as the top plate. Two adjacent bottom plates are fixedly connected together by bolt assemblies passing through a set of parallel straight folded edge mounting holes. The oblique folded edges located at the outer perimeter of the water tank bottom plate are respectively fixedly connected to the oblique folded edges at the lower edges of the four water tank sidewalls by bolt assemblies passing through mounting holes on both. This utility model provides a prefabricated water tank without reinforcing bars, columns, or welding, which allows the lower ends of the water tank sidewalls to be cast into the foundation, or the water tank bottom plate to be fixedly connected to the lower ends of the water tank sidewalls for assembly, thus expanding the applicability of the water tank.

[0012] A further preferred technical solution is that the side plates, top plate, and bottom plate are all provided with reinforcing ribs, with the convex side of the reinforcing ribs facing inwards towards the water tank. The reinforcing ribs improve the structural strength of the side plates, top plate, and bottom plate, allowing for a suitable reduction in their thickness, thus helping to save costs. Furthermore, the convex side of the reinforcing ribs facing inwards towards the water tank makes it less prone to dirt residue on the inner surface of the tank, contributing to improved cleaning efficiency of this rib-free, column-free, and weld-free assembled water tank.

[0013] A further preferred technical solution includes sealing strips at the joints of the side plates, top plate, and bottom plate, and a maintenance manhole on the top wall of the water tank. The sealing strips at the joints of the side plates, top plate, and bottom plate prevent water leakage from the water tank, increasing its sealing performance; the maintenance manhole facilitates maintenance of the inner wall of the water tank and the equipment arranged inside.

[0014] A further preferred technical solution is that the side plates, top plates, bottom plates, and top beam components are all made of one of the following materials: stainless steel plate, galvanized steel plate, or stainless steel-galvanized composite steel plate. The side plates, top plates, bottom plates, and top beam components are all made of corrosion-resistant materials, which can effectively prevent the water tank from corroding and extend the service life of the water tank.

[0015] The advantages and beneficial effects of this utility model are as follows:

[0016] 1. This utility model discloses a prefabricated water tank without bracing, columns, or welding. A set of straight, folded edges on two adjacent side panels of the same side wall are connected together by a clamping assembly, significantly improving the structural strength and pressure-bearing capacity of the side panel joints and effectively preventing water pressure deformation at the joints. The top beam assembly supports the top wall of the water tank, increasing its load-bearing capacity. Simultaneously, the top beam assembly limits and tightens the upper ends of a set of side walls distributed at both ends, further enhancing the overall structural strength of the prefabricated water tank. The tank interior lacks bracing, columns, and other supporting components, truly achieving a prefabricated water tank design without bracing, columns, or welds. Furthermore, the entire structure requires no welding, resulting in a short assembly period. It ensures that the water quality meets the hygiene standards for water-related products and offers advantages such as high strength, strong pressure resistance, low manufacturing cost, convenient internal equipment layout, easy cleaning, and long service life.

[0017] 2. The clamping assembly has a clever and reasonable structural design. The two L-shaped reinforcing plates are well-matched with the set of straight folded edges being clamped, thus ensuring that the clamping assembly has good overall clamping stability for the set of straight folded edges being clamped. Furthermore, the reinforcing plate further improves the long-term stability of the clamping force of the two L-shaped reinforcing plates for the set of straight folded edges being clamped.

[0018] 3. The horizontal edge of the L-shaped reinforcing plate, facing away from the corresponding vertical plate two, is bent to form a vertical plate three extending towards the water tank side, and the length of the vertical plate three in the horizontal section is less than the length of the corresponding vertical plate two in the horizontal section. The vertical plate three improves the structural strength of the L-shaped reinforcing plate, thereby helping to further improve the long-term stability of the clamping force of the clamping assembly on the set of straight folded edges.

[0019] 4. The top beam assembly has a clever and reasonable structural design. The two inclined top plates at the top of the top rod are inserted and fixed inside a corresponding V-shaped groove at the joint of the top wall of the water tank, ensuring that the top beam assembly is firmly installed on the lower side of the top wall of the water tank.

[0020] 5. The upper end of the vertical support rod is inserted into the cavity one of the top rod and the lower end is inserted into the cavity two of the bottom rod, which ensures the positioning and installation convenience of the vertical support rod between the top rod and the bottom rod, while ensuring the overall stability and high structural strength of the top beam assembly.

[0021] 6. The reinforcing ribs improve the structural strength of the side plates, top plates, and bottom plates, allowing for a reduction in their thickness, which helps save costs. The convex side of the reinforcing ribs faces the inside of the water tank, making it less likely for dirt to remain on the inner side of the water tank, thus improving the cleaning efficiency of the assembled water tank without bracing, columns, or welding.
