Description

[Detailed Description of the Invention] The present invention relates to a polygonal cylindrical frame suitable for use in a water tank or the like formed by assembling unit plates.

Temporary water tanks are often required for wastewater treatment and water supply during civil engineering work, and these tanks must be cleared after construction. For this purpose, there is a need for water tanks and the like that are easy to transport, assemble, and disassemble, and that can have a large capacity if necessary.

In response to the above requirements, the present invention assembles unit plates to form a polygonal tank body suitable for an aquarium, etc. When used as an aquarium, the inside of the tank body is treated with water impermeability. It is used by lining it with a bag-like body made of synthetic resin sheet, etc. The present invention provides a prefabricated frame for an aquarium or the like that is easy to assemble and disassemble, has a small volume when disassembled and put together, and has excellent transportability.

To explain the present invention based on the drawings, Fig. 1 is a perspective view of an assembly type frame for an aquarium or the like according to the present invention.
A rectangular cylindrical body is formed, and these cylindrical bodies are stacked in three stages to form a regular octagonal cylindrical body.
Although it does not necessarily have to be a regular polygon, it is convenient to use a regular polygon in terms of site area, frame strength, etc.

An example of the unit plate used in the present invention is the second
As shown in the perspective view, a hoop frame 2 made of H-shaped steel is attached to the upper lateral edge of a square plate 1 (for example, 1 m x 1 m) made of plywood. Tag frame 2
Both ends protrude from the vertical edge of the square plate 1 by an appropriate length,
In this protrusion, a circular through hole 3 is bored in the horizontal girder. That is, the through-hole surface is perpendicular to the plate surface of the unit plate. A hoop frame 4 is similarly attached to the lower lateral edge, but the hoop frame 4 is attached offset from the lower lateral edge by the width of the flange of the H-shaped steel. Further, a reinforcing hoop frame 5 is similarly attached to the middle of the hoop frame 2 and the hoop frame 4 in parallel for reinforcement. This reinforcing hoop frame 5 may not be attached depending on the material and dimensions of the square plate.

The rectangular plate may be a flat plate or a corrugated plate made of plywood, steel, aluminum, etc., and its size is not limited to the above example, but may be any suitable size. Further, as the metal structural material of the hoop frame, H-shaped, chevron-shaped, groove-shaped, T-shaped steel or aluminum shapes, square pipes, etc. are used. When assembling only one type of unit plates, the adjacent plates must be turned upside down and the protruding parts of the hoop frames overlapped, so the attachment positions of these hoop frames must be made accurately.

Next, in order to assemble a frame using this unit plate, use an even number of unit plates of 4 or more for each stage. As shown in the end view of the connecting part in Fig. Arrange the required number of stages by turning them upside down so that the holes in the protruding parts of the hoop frame are aligned in a straight line.
A connecting rod 6 made of a steel pipe is passed through the overlapping through holes (three stages in the illustrated example), and the combined body is erected so that the connecting rods are vertical. In the same way, set up the combined body and adjust the position so that the through holes of the combined body coincide with each other,
The connecting rods 6 are passed through the matching through holes from above, and the connecting rods 6 are connected in the same manner thereafter to form a frame body having a regular polygonal shape of 4, 6, 8, etc. and having one or more stages. . Disassembly can be done by reversing the above steps.

As mentioned above, the frame thus formed is lined with a bag and used as a water tank or the like, or as a storage tank for powder or granules, but if the particles of the powder or granules are large, then It is also possible to store it directly without attaching a bag. Note that when the assembled frame body is used as a water tank or the like, water pressure acts evenly in the direction perpendicular to the inner wall surface, so that the tank body can maintain a substantially regular polygonal shape.

Since the prefabricated frame for an aquarium or the like according to the present invention has the above-described configuration, a frame of any capacity can be quickly and easily assembled after leveling the ground of the site. Moreover, each unit plate is in contact with the frame made of metal structural material and stacked one on top of the other.
Since the edges of the plates do not come into direct contact with each other and no load is applied to the edges, there is no risk of damage to the plates, especially to the edges of the plates. Also, it is easy to dismantle.
When disassembled, it can be assembled into a small volume of flat plates and steel pipes of the same size, making it extremely convenient to store, transport, etc., and has excellent utility as a frame for temporary water tanks and storage tanks for powder and granular materials. have
