Description

Technical Field

[0001] This utility model belongs to the field of building component technology, specifically relating to a PP module rainwater collection tank with structural columns. Background Technology

[0002] In urban flood control, rainwater harvesting modular tanks are commonly used for rainwater collection and discharge. These tanks are constructed by splicing multiple PP modules into a cube shape and embedding it in an underground pit. The surface of the tank is covered with lawn or other decorative materials, which is not only aesthetically pleasing but also effectively collects and discharges rainwater safely and environmentally. The PP modules within the tank are hollow plastic cubes. Multiple PP modules are first arranged horizontally to form a module layer, and then multiple layers are stacked to construct the rainwater harvesting modular tank within the pit. However, because the PP modules are stacked layer by layer, each module is prone to lateral misalignment, causing instability in the lateral pressure bearing capacity of the entire modular tank. Furthermore, the numerous breaks between modules during installation reduce the overall stability of the modular tank. Utility Model Content

[0003] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a PP modular rainwater collection tank with structural columns. The structural columns are vertically inserted into the module body to achieve vertical connection of the module body, so that the module tank will not produce lateral layer misalignment, thereby improving the lateral pressure bearing capacity and overall stability of the module tank.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

The connection holes of a pair of modules that are adjacent vertically connected are interconnected. At least the outermost vertically connected connection holes are inserted into the structural columns.

[0006] Furthermore, the outer periphery of the support plate is provided with trapezoidal connecting grooves, and the trapezoidal connecting grooves on the horizontally adjacent support plates are connected to each other, and a connecting block is embedded in a pair of connected trapezoidal connecting grooves.

[0009] Furthermore, the support column has a frustum structure, and one end of the support column extends out of the support plate.

[0010] Furthermore, the end of the support column connected to the support plate is open, and the end extending out of the support plate is closed.

[0011] Furthermore, the outer periphery of the support column is provided with axial grooves.

[0012] Furthermore, the cross-section of the connecting hole is polygonal, and the outer periphery of the cross-section of the structural column matches the polygonal shape.

[0022] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so as to better understand the purpose, features and advantages of the present invention. It should be understood that the embodiments shown in the drawings are not intended to limit the scope of the present invention, but are only for illustrating the essential spirit of the technical solution of the present invention.

[0023] like Figures 1-5 As shown. This utility model provides a PP modular rainwater collection tank with structural columns, including modular bodies. Several modular bodies are arranged horizontally adjacently in a single layer, and several layers are stacked vertically. Each modular body is composed of a pair of modules 1 connected vertically. Module 1 includes a support plate 11 and a support column 12. The support plate 11 is provided with connection holes 13. The support columns 12 are arranged in an array on one side of the support plate 11. The ends of the support columns 11 of a pair of modules are connected to each other. The vertically adjacent connection holes 13 of a pair of modules are interconnected. At least the vertically interconnected connection holes 13 on the outermost ring are into which structural columns 2 are inserted.

[0024] Specifically, the support plate 11 of each module 1 is formed by connecting two cubes of equal size into a rectangular plate structure. A connection hole 13 is provided in the center of each cube. Four support columns 12 are arranged in an array at one end of each cube. The support columns 12 are vertically connected to the support plate 12 and located on the outer periphery of the connection hole.

[0025] The horizontal and vertical connections of the support plate of module 1 form a layer, and the upper and lower modules are connected by inserting structural columns into the connection holes 13.

[0026] To save on the number of structural columns, as a preferred option, structural column 2 is inserted into the connection hole 13 of the upper and lower adjacent modules of the outermost ring, so that the modules of the outer ring form a fixed ring.

[0027] Each module is made of acrylic copolymer polyvinyl chloride plastic in one piece through molding.

[0028] Furthermore, in order to facilitate the connection of the horizontal module 1, trapezoidal connecting grooves 16 are arranged in an array on the outer periphery of the support plate 11. The trapezoidal connecting grooves 16 on horizontally adjacent support plates 11 are connected to each other, and a connecting block is embedded in a pair of connected trapezoidal connecting grooves 16.

[0029] Specifically, the trapezoidal connecting groove facing the inner side of the support plate is wide, and the connecting block is a double trapezoidal structure that matches a pair of adjacent trapezoidal connecting grooves 15. The double trapezoidal structure is plate-shaped, and its longitudinal cross-section is like the cross-section of a funnel. The connecting block and the trapezoidal connecting groove 16 facilitate the horizontal connection of the support plate 11, so that the module is firmly connected in the horizontal direction.

[0030] Furthermore, to effectively support the soil covering within the foundation pit, connecting plates are embedded on the outer periphery of at least the outermost adjacent layers of module 1. The upper and lower ends of the connecting plates are respectively engaged with the support plate 11. The connecting plates create a closed surface on the outer periphery of the connected module 1. This closed surface not only enhances the strength of module 1 but also prevents soil covering from entering the module body when burying the foundation pit.

[0031] Furthermore, the edge of the support plate 11 is provided with protrusions, and the upper and lower ends of the inner surface of the connecting plate are provided with grooves that match the protrusions, with the protrusions embedded in the corresponding grooves.

[0032] Specifically, the lower ends of the opposite sides of the outer periphery of the support plate 11 are provided with protrusions, and the upper and lower sides of the inner surface of the connecting plate are provided with grooves. The protrusions and grooves match each other. When the support columns of the upper and lower adjacent modules are connected, the upper and lower ends of the connecting plate are engaged by the grooves and protrusions to make the connecting plate embedded in the outer periphery of the upper and lower modules.

[0033] Furthermore, in order to improve the support strength, the support column 12 is a frustum structure, and one end of the support column 12 extends out to the support plate 11.

[0034] Specifically, the frustum structure is a conical cavity with a support plate 11 extending from one end. The area of ​​the frustum end face extending from the support plate 11 is smaller than that of the end connected to the support plate. The end of the frustum structure connected to the support plate 11 is open, while the other end is closed.

[0035] Furthermore, in order to improve the structural strength of the support column, axial grooves are provided on the outer periphery of the support column.

[0036] Furthermore, to strengthen the connection, the cross-section of the connecting hole is a polygonal structure, and the outer perimeter of the structural column's cross-section matches this polygonal structure. Inserting the structural column into the connecting hole achieves a secure connection, preventing the structural column from rotating.

[0037] Furthermore, in order to improve the connection strength of the module body, a mating hole 14 is provided on one end of the support plate, and a connecting pipe 15 is provided on the other end of the support plate 11. The upper and lower opposite connecting pipes 15 and the mating hole 14 are inserted and matched.

[0038] Specifically, when the modules are connected vertically, the support plates 11 are attached to each other. At this time, since two cubes of equal size are connected to form a rectangular plate structure, one of the cubes has four docking holes 14 arranged in an array, and the other cube has four docking tubes 15 arranged in an array. When connecting, the docking tubes 15 of the previous support plate are inserted into the docking holes 14 of the next support plate to achieve docking.
