Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a prefabricated aquarium, and more specifically, the present invention relates to a prefabricated aquarium, in particular, a plurality of unit panels having joint edges are connected to each other with the joint edges facing inside the tank, and the ceiling is This relates to a prefabricated aquarium with a step.

(Prior art) Installation in a prefabricated aquarium in which a side wall, a bottom wall, and a ceiling are constructed by combining a plurality of unit panels having joint edges around the four peripheries of a right-angled substrate with the joint edges facing inside the tank. Due to space constraints,
It is known that a part of the ceiling is made low to avoid obstacles.

In this case, the joining edges of the unit panels that make up the ceiling of the low part become a barrier, and even if the water level in the tank is higher than the ceiling of the lower part, air remains above the ceiling of the low part, resulting in The bolts and nuts that connect the connecting edges of the unit panels that make up the ceiling in the lower part are susceptible to corrosion, and the effective capacity of the water tank is also reduced.

(Means for Solving the Problems) The present invention has been devised in view of the above-mentioned conventional problems, and provides for openings at the joint edges of unit panels constituting the ceiling of a low section at positions above the fastening bolt holes. When the water level in the tank reaches the ceiling of a low part, the air above the ceiling of the low part passes through the notch or through hole to the top of the ceiling of the high part. Let it be drained,
Air does not remain in the upper part of the ceiling in the low part, which prevents the fastening bolts in this part from corroding and increases the effective capacity of the water tank.

(Example) Hereinafter, the specific structure of the present invention will be explained based on the example shown in FIGS. 1 to 3.

FIG. 1 is a partially cutaway perspective view of a prefabricated aquarium according to the present invention, and FIGS. 2 and 3 are perspective views showing unit panels used in the present invention.

In Fig. 1, 1 is a rectangular board with a plurality of unit panels having joint edges around the four peripheries joined together with their joint edges 2 facing inside the aquarium, and a stepped ceiling, that is, a low ceiling. It constitutes X and the high ceiling Y.

A notch 3 is formed in the joint edge 2 of the unit panel 1 that constitutes the ceiling X in the lower part.

The depth of the notch 3 is deeper than the position of the fastening bolt/nut connecting the joint edges 2 together.
That is, as shown in FIG. 2, a notch 3 that opens at a position above the fastening bolt hole 21 is formed in the joint edge 2 of the unit panel 1.

Therefore, when the water level in the tank reaches the position of the ceiling X in the low part, the air above the ceiling This prevents air from remaining in the bolts and nuts that fasten the joint edges 2 of the unit panels 1 forming the ceiling X in the lower part.

The unit panel 1 constituting the ceiling X in the lower part is not limited to one in which a notch 3 is formed in the joint edge 2 as shown in FIG. 2, and a fastening bolt is formed in the joint edge 2 as shown in FIG. The through hole 3 may be formed to open at a position above the hole 21 position.

(Effect of the invention) Since the present invention has the above-mentioned configuration, when the water level in the tank reaches the ceiling position of a low part in a prefabricated aquarium with a stepped ceiling, the upper part of the ceiling of the low part The air is discharged to the upper part of the ceiling of the high part through a notch or a through hole formed in the joint edge of the unit panel so as to open at a position above the fastening bolt hole position. Therefore, it is possible to prevent the corrosion of the bolts and nuts that fasten the unit panels due to air remaining in the upper part of the ceiling in the low part as in the past, and it is also possible to increase the effective capacity of the water tank. There are various advantages.

[Brief explanation of drawings]
