Description

[Technical Field]

[0001] The present invention relates to an aquarium having an aeration pipe and a support for placing the aeration pipe within the aquarium. [Background technology]

[0002] As a means for supporting air diffuser pipes installed in water tanks such as aeration tanks and drainage tanks, there is a first method in which, before pouring the concrete to form the water tank, metal angle bars are buried so that a portion of them protrudes from the floor, and after pouring the concrete and applying a mortar finish, a finish paint or, if necessary, a chemical-resistant paint is applied to the concrete surface, and then U-bolts are connected to the protruding portion to secure the air diffuser pipe. A second method is to bury a metal plate together with a fixing rod that supports it before pouring the concrete on the floor, and after pouring the concrete, applying a mortar finish, a finish paint, etc. in the same manner as above, weld a rod-shaped member to the metal plate fixed to the concrete floor, connect the angle bar to the rod-shaped member, and connect a U-bolt to the angle bar to secure the air diffuser pipe.

[0003] The above support means has a problem in that many protruding angle irons require each angle iron to be cured during concrete pouring, which impairs workability. Also, when applying a finish coat (chemical-resistant coating) to the floor surface, the protruding angle irons get in the way, making the work difficult. Furthermore, because the metal fittings (angle irons, etc.) need to be embedded in the floor in time for the concrete pouring, the work arrangements must be made with due consideration of the civil engineering work schedule for the water tank itself, which is time-consuming.

[0004] Furthermore, in the case of the second means, welding work is required, which increases the work costs.

[0005] Patent Document 1 describes a solution to the above-mentioned problems by describing a fluid piping support member that includes a weight member that is placed on the floor of the water tank and supports the fluid piping, which is the object to be supported, at a predetermined position against the buoyancy of the liquid stored in the water tank, and a mounting member that is provided on the weight member and can be adjusted to any height to mount a pipe connecting member for fixedly connecting the fluid piping, and an aeration pipe installation structure that uses this support member.

[0019] The air diffuser support of the present invention is installed by being placed on the bottom of the water tank, and even if the arrangement position (layout) of the air diffuser pipes is changed, the installation position can be freely changed to match the change.

[0020] When the air diffusion pipe support of the present invention is used, the number of days required for the installation of the air diffusion pipe can be significantly reduced. [Brief explanation of the drawings]

[0021] [Figure 1] 1 is a perspective view of the bottom portion of a water tank in which an air diffuser tube is installed using an air diffuser tube support according to an embodiment of the present invention. FIG. [Figure 2] FIG. 2 is a vertical cross-sectional view of the air diffuser support of FIG. 1. DETAILED DESCRIPTION OF THE INVENTION

[0022] Hereinafter, an embodiment will be described with reference to FIGS.

[0023] The air diffuser support 1 comprises a tubular body 2 made of PVC (vinyl chloride resin), a through-pipe 3 that passes through the tubular body 2 in the diameter direction midway along the axial direction of the tubular body 2, and concrete 4 that is filled inside the tubular body 2 and outside the through-pipe 3. In this embodiment, the tubular body 2 is cylindrical. An end plate 5 is provided at one end (the upper end in the figure) of the tubular body 2, and an end plate 6 (not shown in FIG. 1) is provided at the other end.

[0024] This air diffuser support 1 is manufactured by filling concrete 4 inside the cylindrical body 2 (and outside the through pipe 3) in which the through pipe 3 and end plate 5 are bonded together with PVC adhesive, and after the concrete has hardened, attaching the end plate 6 with a rubber plate 7 with adhesive. However, this manufacturing procedure is one example, and other manufacturing procedures may also be used.

[0025] This aeration pipe support 1 is placed on the bottom surface 8 of a water tank such as an aeration tank via a rubber plate 7. In this case, the axial direction of the cylindrical body 2 is set to the up-down direction. A required number of aeration pipe supports 1 are placed at required positions on the water tank bottom surface 8 at appropriate intervals. By inserting the aeration pipes 10 through the through pipes 3 of the aeration pipe support 1, the aeration pipes 10 are disposed along the water tank bottom surface 8 at a predetermined distance above the water tank bottom surface 8.

[0026] In a configuration in which the air diffusion pipes are arranged using this air diffusion pipe support 1, the air diffusion pipe support 1 is placed on the water tank bottom surface 8, so the lining of the water tank bottom surface 8 is not damaged. In addition, no welding work is required during installation, making installation easy and requiring only a short number of days. Furthermore, even if it becomes necessary to change the arrangement pattern of the air diffusion pipes after installation is complete, the air diffusion pipe arrangement pattern can be changed by moving the air diffusion pipe support 1 to another position or changing the direction of the air diffusion pipe support 1.

[0027] This air diffuser support 1 does not use a metal material, and therefore is highly durable and will not deteriorate over the long term, even if the water in the tank is highly corrosive.

[0028] The above-described embodiment is an example of the present invention, and the present invention can be embodied in other forms.

[0029] For example, in the above embodiment, only one through pipe 3 is provided, but two or more may be provided. When two through pipes are provided, one through pipe may be provided below the other through pipe so that the two through pipes are perpendicular to each other in a plan view. Such an air diffuser pipe support can be used when arranging air diffusers perpendicular to each other.

[0030] In the above embodiment, the cylindrical body is filled with concrete, but it may be filled with mortar.

[0031] In the above embodiment, the air diffuser support 1 has a rubber plate 7 attached to the bottom surface, but the rubber plate 7 may be a separate piece. A resin plate may be used instead of the rubber plate. Also, the air diffuser support 1 may be placed directly on the bottom surface of the tank without using a rubber plate. However, it is preferable to use a rubber plate.

[0032] In the above embodiment, the cylindrical body etc. is made of PVC, but it may be made of plastic (synthetic resin) other than PVC. [Explanation of symbols]
