Description

Technical Field

[0001] This utility model relates to the field of BDF composite panel water tanks, specifically to an assembled BDF composite panel water tank. Background Technology

[0002] BDF composite panel water tank (full name "BDF assembled stainless steel composite panel water tank") is a new type of modular water storage equipment. Its core advantage lies in combining the performance advantages of different materials, and it has the characteristics of strength, corrosion resistance and lightweight. It is widely used in building water supply, fire water storage, secondary water supply and other scenarios.

[0003] In the existing BDF prefabricated stainless steel composite plate water tank, the tie rods used in the assembly process need to be pre-drilled in the BDF composite plate. Then, bolts, washers, sealing rings and nuts are used to fix and lock the tie rods. Since there are holes in the BDF composite plate, and the main seal at this point is the sealing ring which is locked with bolts, leakage is likely to occur at this point when the water pressure inside the tank is high or when the tank is used for a long time. Utility Model Content

[0004] The purpose of this invention is to provide a prefabricated BDF composite panel water tank to address the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an assembled BDF composite panel water tank, comprising a tank body, the tank body comprising a base, an outer frame and a plurality of composite panels, the outer frame being bolted to the base, the plurality of composite panels being bolted to the outer frame, and adjacent composite panels being fixed together by bolts; The four composite panels are provided with a cross-shaped sealing gasket at their junctions. A cross-shaped fixing plate is embedded in one side of the sealing gasket, and a tensioning assembly is provided between the fixing plates on opposite sides inside the box.

[0006] Preferably, both the sealing gasket and the fixing plate have round holes inside that correspond to the connecting bolts of the composite box plate.

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0016] This utility model provides, for example Figures 1-6 The illustrated prefabricated BDF composite panel water tank includes a tank body 1. The tank body 1 includes a base 11, an outer frame 12, and several composite panels 13. The outer frame 12 is bolted to the base 11, and the composite panels 13 are bolted to the outer frame 12. Adjacent composite panels 13 are fixed together by bolts. The base 11 and the outer frame 12 are both existing technologies. For example, the base 11 is generally formed by connecting several channel steels with right-angle connectors, and the outer frame 12 is made of angle steel. Generally, the water tank is formed by directly connecting several composite panels 13 with bolts. In addition, the frame 12 only reinforces the edges of the water tank and can be selected according to the actual situation. The composite panels 13 are selected according to the actual situation and generally have three layers: from the inside to the outside, they are the water contact layer (i.e., the inner layer, composed of food-grade stainless steel plate), the insulation layer (i.e., the middle layer, composed of high-density polyurethane foam), and the protective layer (i.e., the outer layer, composed of galvanized steel plate). Four composite box panels 13 are provided with a cross-shaped sealing gasket 2 at their junctions. A cross-shaped fixing plate 22 is embedded in one side of the sealing gasket 2. A tensioning component is provided between the fixing plates 22 on opposite sides inside the box 1.

[0017] Furthermore, both the sealing gasket 2 and the fixing plate 22 have round holes inside that correspond to the connecting bolts of the composite box plate 13.

[0018] Furthermore, the cross-shaped sealing gasket 2 has an inwardly recessed end forming a junction 21. The thickness of the junction 21 is half the thickness of the sealing gasket 2. In this way, when two adjacent sealing gaskets 2 are spliced ​​together, there is no gap at the junction of the two sealing gaskets 2, which greatly reduces the possibility of water tank leakage.

[0019] Furthermore, the tensioning assembly includes a limiting plate 23, which has a cross-shaped structure and is welded to one side of the fixing plate 22. The limiting plate 23 is provided with a sliding connecting frame 3 on the outside. One side of the connecting frame 3 is fixed with connecting plates at the top and bottom of the fixing plate 22. A through hole is opened between the two connecting plates. Several fixing holes 24 matching the through hole are opened inside the fixing plate 22. A fixing bolt 31 is connected between the two connecting plates. The fixing bolt 31 passes through the through hole on the connecting plate and the fixing hole 24 on the fixing plate 22. A tie rod 4 is welded between the two connecting frames 3 on opposite sides inside the box 1.

[0020] Specifically, the fixing plate 22, the limiting plate 23, the connecting frame 3, the fixing bolt 31, and the tie rod 4 are all made of food-grade stainless steel.

[0021] Specifically, the sealing gasket 2 is made of food-grade EPDM rubber strip.

[0022] Through the above technical solution: During use, during the assembly of the water tank, after the composite tank panel 13 is assembled, the sealing gasket 2 and the fixing plate 22 are also fixed, thereby sealing the gaps between the composite tank panels 13 (in the attached drawings of this specification, the sealing gasket 2 and the fixing plate 22 are located in the middle of the water tank, at which time the sealing gasket 2 and the fixing plate 22 have a cross-shaped structure. When the sealing gasket 2 and the fixing plate 22 are located at the edge of the water tank, the sealing gasket 2 and the fixing plate 22 present the shape of the gap at the edge of the water tank, which is easy to imagine. Of course, the edge can also be sealed with the existing sealing strip and sealant, which will not be elaborated here). After the fixing plate 22 is fixed, the connecting frame 3 is slid directly from the side of the fixing plate 22 to the outside of the limiting plate 23. Then, the connecting plate is fixed on the fixing plate 22 through the fixing bolt 31 and the fixing hole 24, thereby locking the position of the connecting frame 3 (the fixing bolt 31 is a bolt and nut assembly), which makes it convenient to achieve the subsequent composite plate 13 without openings and still be able to fix the tie rod 4. After the position of the connecting frame 3 is determined, the tie rod 4 is welded between the two opposing connecting frames 3 inside the water tank. During installation, the tie rod 4 can be pre-welded to the connecting frame 3 off-site to further improve the ease of assembly of the tie rod 4 and the connecting frame 3 (since there are several fixing holes 24, please refer to the instruction manual for details). Figure 6 Therefore, the position of the connecting frame 3 can also be adjusted to prevent it from affecting the subsequent installation of the vertical tie rod 4 of the water tank. Since the tie rod 4 and all related components for fixing the tie rod 4 are located inside the water tank, the corrosion rate of the related components for fixing the tie rod 4 is greatly reduced, and the probability of water tank leakage is reduced. In this case, the component structure is simple and the assembly is reasonable, which can greatly improve the convenience of water tank assembly.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
