[0029] Large water tanks are typically manufactured on-site in a modular fashion. Conventionally, they are typically cylindrical structures, formed by connecting curved steel plates. However, cylindrical water tanks have limited applicability and require high precision in both individual components and assembly, making assembly more difficult.

[0030] For rectangular water tanks, which are more widely applicable, welding is usually used for preparation. However, the welding method has a long construction period and poor flexibility in volume adjustment.

[0031] Regarding the problems in related technologies, such as Figure 1-Figure 3 As shown, this embodiment provides an assembled rectangular water tank, including wall panels 10, connecting angle steels 50, joint columns 20 and joint stirrups 30. Four wall panels 10 are spliced ​​together to form the water tank body, and corner joint seams extending in the vertical direction are formed between adjacent wall panels 10; each wall panel 10 includes a plurality of single plates 11, and a transverse joint seam is formed between every two stacked single plates 11, and the multiple transverse joint seams are on the same horizontal line; a vertical joint seam is formed between every two parallel single plates 11, and the multiple vertical joint seams are on the same vertical line; the connecting angle steels 50 are connected to the corresponding single plates 11 by bolts. On the two adjacent wall panels 10, the connecting angle steel 50 is arranged along the extension direction of the corner connection seam and is located on the inner side of the corner connection seam; the joint column 20 is connected to the parallel single plate 11 by bolts, and the joint column 20 is arranged along the extension direction of the vertical connection seam and is located on the outer side of the vertical connection seam; the joint stirrup 30 is connected to the parallel adjacent single plate 11 by bolts, and the joint stirrup 30 is arranged along the extension direction of the transverse connection seam and is located on the outer side of the transverse connection seam; wherein, a sealant layer is provided in the corner connection seam, the transverse connection seam and the vertical connection seam, and the sealant layer is used to seal the gap. Water tanks that require a larger volume are usually prepared using a modular connection method. In this embodiment, the wall panels 10 on each side are composed of multiple single panels 11, and the gaps between adjacent single panels 11 are correspondingly connected by joint columns 20 and joint stirrups 30, so that the gaps between adjacent single panels 11 can be stably sealed, and the water tank body can be quickly assembled and the volume can be flexibly adjusted through bolt connections.

[0032] Specifically, the water tank body is formed by connecting four wall panels 10. That is, the four wall panels 10 form the four side walls of the water tank body. Adjacent wall panels 10 are connected by connecting angle steels 50, so as to achieve the structural stability of the entire water tank body.

[0033] During assembly, the single plate 11 is a rectangular block structure, and bolt holes are provided at the four edge positions of the single plate 11, so that the bolts can pass through the bolt holes and be fastened to the joint columns 20 or joint stirrups 30 during connection, thereby improving the stability of the water tank body.

[0034] It is understandable that when modular single panels 11 are spliced ​​together, it is necessary to address the stability of the spliced ​​joints, as well as the overall pressure-bearing and sealing performance. In this embodiment, adjacent single panels 11 are connected by bolts with joint columns 20 and joint stirrups 30, so that the vertical and horizontal gaps between adjacent single panels 11 have a relatively stable splicing structure. The joint columns 20 and joint stirrups 30 also enhance the overall stability of the wall panel 10, making the splicing between the single panels 11 more stable and more pressure-bearing.

[0035] It should be noted that the bolt connections described in this application all require the application of sealant to achieve a tight seal at the connection location. Specifically, sealant is applied to the bolt holes and bolts before threaded connections are made, thereby making the bolt connection a sealed structure to prevent liquid leakage inside the water tank.

[0036] In a specific configuration, the single board 11 can have various plate specifications. Single boards 11 of the same specifications can be stacked and spliced, and single boards 11 of different specifications can be stacked and spliced ​​side by side to form a whole wall panel 10. Of course, to ensure the stability and convenience of the connection of the joint stirrups 30, the transverse connection seam formed by the stacking of single boards 11 of different specifications is on a straight line.

[0037] For example, if Figure 1 、 Figure 3 As shown, the single board 11 on the same wall panel 10 has two specifications: one is a 2.5-meter-long long board 111, and the other is a 1.25-meter-long short board 112. The long board 111 and the short board 112 differ only in length, and are consistent in width and thickness. Two 2.5-meter-long long boards 111 are stacked to form a long board 111 stacking area, and two 1.25-meter-long short boards 112 are stacked to form a short board 112 stacking area. The long board 111 stacking area and the short board 112 stacking area are spliced ​​side by side, and the outer joint columns 20 are used to achieve stable splicing at the parallel position, thereby improving the overall structural strength of the water tank and the stability of the splicing. Of course, the single board 11 in this embodiment can also be of other specifications. Those skilled in the art can adapt to different specifications according to design requirements to achieve the configuration of water tanks of different sizes.

[0038] In a specific embodiment, the joint column 20 and the connecting angle steel 50 are both integral structures, that is, the joint column 20 and the connecting angle steel 50 extend from the bottom surface of the wall panel 10 to the top of the wall panel 10, thereby realizing the connection of the vertical connection seam on the entire wall panel 10, which can improve the overall bearing capacity and the structural strength of the water tank.

[0039] According to one embodiment provided by the present invention, the rectangular water tank further includes a first connector 60, one end of which is bolted to one end of the joint stirrup 30, and the other end of the first connector 60 is bolted to the joint column 20. When the rectangular water tank is modularly connected, it is necessary to ensure the stability of the joints and the overall structural strength. In this embodiment, the joint stirrup 30 is connected to the joint column 20 by the first connector 60, thereby making the connection of the joint stirrup 30 more stable, improving the stability of the connection, and enhancing the overall structural strength of the water tank body.

[0040] Specifically, the first connecting member 60 is an L-shaped structure, and two groups of bolt holes are provided at both ends of the first connecting member 60. Each bolt hole group includes a plurality of bolt holes arranged at intervals. The bolt holes in each group correspond to the single plates 11 on the upper and lower sides of the transverse connecting seam, thereby achieving an overall stable connection, so that the joint stirrups 30 have a stable connection structure.

[0041] It can be understood that, through the setting of the connecting parts, the horizontally connected joint stirrups 30 and the vertically connected joint columns 20 are connected to form an overall outer frame structure, thereby improving the overall structural stability and making the water tank more pressure-bearing.

[0042] In some embodiments, such as Figure 4 As shown, a first connecting portion 31 is provided at one end of the joint stirrup 30 located at the vertical edge of the wall panel 10. The first connecting portion 31 connects the joint stirrups 30 on adjacent wall panels 10. During the assembly of the water tank, in addition to connecting adjacent wall panels 10 on the inside via the connecting angle steel 50, the first connecting portion 31 also connects the outsides of two wall panels 10, thereby enhancing the overall structural strength and the load-bearing capacity of the water tank.

[0043] Specifically, adjacent wall panels 10 are joined at right angles, primarily via connecting angle steel 50 located on the inside. This connection provides a high-strength connection across the entire water tank. On the outside, first connecting portions 31 connect the seam stirrups 30 on adjacent wall panels 10, thereby enhancing the overall structural strength of the water tank.

[0044] In the specific setting, the first connecting part 31 includes a first connecting block, which is provided with a bolt hole. It is connected to the joint stirrups 30 of another wall panel 10 through the bolt holes on the first connecting block, thereby realizing the connection of the joint stirrups 30 on the wall panels 10 on the adjacent two sides.

[0045] In some embodiments, at least one reinforcement column is provided on the wall panels 10 between the vertical joint and the corner joint; and / or at least one reinforcement column is provided on the wall panels 10 between adjacent vertical joints. The water tank needs to be filled with a certain amount of water, which requires the entire tank to have a high pressure-bearing capacity. In this embodiment, the provision of reinforcement columns can further improve the overall pressure-bearing capacity, achieving overall high-strength pressure-bearing capacity.

[0046] Specifically, when a single board 11 is too long, one or more reinforcing columns are required to be installed in the middle of the single board 11 to provide overall support, thereby improving the overall structural strength and its internal pressure-bearing capacity. Specifically, when multiple long single boards 11 are installed on the same wall panel 10, reinforcing columns are installed between adjacent vertical joints of the same wall panel 10. Similarly, when a long single board 11 is used as a panel body for splicing adjacent wall panels 10, reinforcing columns are required between the vertical joints and the corner joints.

[0047] For example, if Figure 1 、 Figure 3 As shown, the longer single board 11 in the figure serves as the connecting plate between adjacent wall panels 10. Therefore, a reinforcing column is provided between the vertical joint and the corner joint, thereby enhancing the overall structural strength. Of course, two or more reinforcing columns can also be provided, depending on the length of the single board 11. If the length of the single board 11 is too long, multiple reinforcing columns can be arranged to improve the strength of the connection.

[0048] In the specific setting, the spacing between adjacent reinforcement columns and the spacing between the reinforcement columns and the joint columns 20 are all the same. This setting can make the frame structure formed on the outside stronger and can meet higher pressure requirements.

[0049] In some embodiments, the reinforcement columns are arranged in parallel with the joint columns 20. The parallel arrangement facilitates the assembly of the reinforcement columns and enables quick connection of the reinforcement columns.

[0050] It is understood that the parallel arrangement facilitates the connection of the joint stirrups 30, thereby improving the convenience of connection. Moreover, the arrangement of the joint columns 20 and the joint stirrups 30 forms a grid-like structure frame around the periphery of the water tank, thereby improving the overall structural strength of the water tank.

[0051] In some embodiments, one end of the joint stirrup 30 is bolted to the reinforcing column via a first connector 60. The provision of the reinforcing column causes the joint stirrup 30 to be continuously interrupted laterally, and the provision of the first connector 60 connects the joint stirrup 30 to the reinforcing column, thereby improving the overall connection strength.

[0052] In some embodiments of the present invention, at least one reinforcing stirrup 40 is provided between adjacent seam stirrups 30. To improve the pressure bearing capacity of the single board 11, the reinforcing stirrup 40 in this embodiment can enhance the structural strength of the single board 11, thereby enhancing the overall structural strength of the water tank.

[0053] It can be understood that the single plate 11 is a plate structure, and the arrangement of the reinforcing stirrups 40 can enhance the structural strength of the single plate 11 and ultimately make the formed water tank have a higher pressure bearing capacity.

[0054] In some embodiments, the reinforcing stirrups 40 are arranged parallel to the seam stirrups 30. The seam stirrups 30 are connected to the upper and lower edges of the single board 11, which can connect the two spliced ​​boards. The reinforcing stirrups 40 are arranged between the upper and lower seam stirrups 30, thereby providing the entire single board 11 with higher structural strength.

[0055] It is understandable that there is no limit to the number of reinforcement stirrups 40 arranged, and technical personnel in this field can make corresponding adjustments according to actual needs. For example, when the width of the single plate 11 is larger, the number of reinforcement stirrups 40 can be increased, and when the width of the single plate 11 is smaller, the number of reinforcement stirrups 40 can be reduced.

[0056] In some embodiments, a second connector 70 is provided at one end of the reinforcing stirrup 40, and one end of the reinforcing stirrup 40 is connected to the joint column 20 and / or the reinforcing column via the second connector 70. The reinforcing stirrup 40 is arranged transversely and is connected to the joint column 20 and / or the reinforcing column during connection, thereby forming an integral frame structure on the outside, further improving the overall connection strength.

[0057] Specifically, the second connecting member 70 has the same structure as the first connecting member 60, and is also constructed as an L-shaped structure. The width of the second connecting member 70 is smaller than that of the first connecting member 60. Only one set of bolt holes needs to be set on the second connecting member 70, so as to realize the connection between the second connecting member 70 and the column and the reinforcing stirrups 40, ensuring that the peripheral frame structure has a higher structural strength.

[0058] In some embodiments, a second connecting portion 41 is provided on one end of the reinforcing stirrup 40 located at the vertical edge of the wall panel 10. The second connecting portion 41 is connected to the reinforcing stirrup 40 on the adjacent wall panel 10 by bolts. This connection method can further enhance the integrity of the peripheral frame, thereby improving the stability of the peripheral overall frame.

[0059] It can be understood that when the reinforcing stirrups 40 are connected transversely, the adjacent reinforcing stirrups 40 can be connected through the second connecting portion 41, which improves the integrity and further increases the structural strength of the water tank as a whole.

[0060] In the specific setting, the second connecting part 41 has the same structure as the first connecting part 31, which includes a second connecting block with a bolt hole provided on the second connecting block. It is connected to the reinforcing stirrups 40 of another wall panel 10 through the bolt holes on the second connecting block, thereby realizing the connection of the reinforcing stirrups 40 on the wall panels 10 on the adjacent two sides.

[0061] Through the description of the above embodiments, those skilled in the art will clearly understand that the splicing of multiple panels 11 in each embodiment facilitates construction, enabling rapid assembly and connection, reducing installation time. Furthermore, the splicing of multiple panels 11 facilitates flexible volume adjustment, improving the applicability of the water tank. Furthermore, the modular design eliminates the need for design verification for a given height, reducing design time and enabling larger volumes. Furthermore, the combination of splicing and sealant reduces the risk of leakage and improves the water tank's sealing performance.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
