Note that 22 is a tightening nut. Incidentally, this assembled water tank A has a joining flange 24 on the periphery, and a reinforcing strip 25 slightly shorter than the joining flange 24 is applied to the inner surface of the joining flange 24 where the necessary panels 23 come into contact with each other, and bolts and nuts are 2
6 and 27 to assemble and form the side peripheral wall _A2 , and cover the upper and lower openings of the side peripheral wall _A2 with the ceiling wall _A3 and the bottom wall _A1 assembled and formed using the desired panel _A1 '. The side peripheral wall _a2 of this assembled water tank A is reinforced with an outer support D.

The side peripheral wall _a2 of the assembled aquarium A consists of the necessary long panels 23-1 arranged at the highest stage and having a width of 1 m and a total height of 1.5 m or 2 m, and the required long panels 23-1 arranged at the lower stage of the long panels 23-1. The four sides of the side wall surface _{a 2} ' formed by fastening the joint flanges 24 with the required panels of the general panel 23-2 with a front square (1 m square) with bolts and nuts 26 and 27 are interconnected. The figure shows what is constructed by the following. This is because a 1m square general panel 23-2, which has a small amount of deformation due to water pressure, is placed on the lower stage where high water pressure acts, and although it has a large amount of deformation due to water pressure compared to the general panel 23-2, it contributes to a drastic reduction in the number of connection points. By arranging the long panel 23-1 on a high stage, a side peripheral wall _a2 with small outward bulging deformation in response to internal pressure can be formed.
Furthermore, consideration has been given to reducing the size of the outer support D used. By the way, the outer support D used is 125mm x in the assembled aquarium A with a total height of 2.5m shown in the diagram.
Weight 6.31Kg/with cross-sectional dimensions of 50mm x 20mm x 3.5mmt
A metal C-type channel material of 1.5 mm was used. The outer strut D is a metal C-shaped channel member formed by cutting the end face to a length equivalent to the height of the side peripheral wall _a2 of the assembled water tank A, and is connected to the reinforcing strip plate 25 by connecting it vertically. The cross-shaped joint Y in the side walls of the panels 23-1 and 23-2 is connected via the connector 28 in a state in which the reinforcing strips 25 and 25 are in contact with the protruding end surfaces attached to the inner surfaces of the flanges 24 and 24. Attach to the side peripheral wall A ₂ by connecting to.

The connector 28 is a reinforcing strip plate 25, 2 attached to the inner surface of the joint flanges 24, 24 installed horizontally on both sides of the outer support column D facing the cross-shaped joint Y of the side peripheral wall.
Bolt the reinforcing bent piece 35 that comes into contact with the protruding end surface of 5.
This bent piece 2 is fixed via nuts 29 and 30.
A connecting bolt 31 passing through 5 and 25 and a panel 2
3-1, 23-2 and a mounting bolt 33 which fastens the fastening nut 32 and is connected via an intermediate nut 34.

The reinforcing bent piece 35 is attached to the outer support D as shown in the figure.
a mounting piece part 35-1 for fixing bolts and nuts 29, 30 to the side surface of the mounting part 35-1; a seat part 35-2 of the connecting bolt 31 bent from the mounting part 35-1;
The pressing piece 35-2 is bent from the seat piece 35-2 toward the side peripheral wall _a2 , and its tip abuts against the tip end surface of the reinforcing strips 25, 25 attached to the inner surfaces of the horizontally installed joint flanges 24, 24. 3 by bending a single metal plate, and using the connecting tool 28, the outer support D is connected to the long panel 23-1 and the general panel 2.
3-2 When the reinforcing strip plate is attached to the inner surface of the joint flanges 24, 24, which are horizontally installed as described above, the pressing piece 35-3 is automatically attached to the inner surface of the joint flanges 24, 24, which are installed horizontally as described above. 25, 25 has the role of forming a stronger joint structure at the cross-shaped joint Y of the side peripheral wall by pressing the protruding end surfaces.

By the way, the outer support D is the cruciform joint Y of the side peripheral wall.
In addition, the connectors are also installed at a location opposite to the joining flange 24 at the outer edge of panel a ₁ ′ that constitutes the ceiling wall a ₃ and at a location opposite to the joining flange 24 at the outer edge of panel a _{1 ′} that constitutes the bottom wall a 1 . 28 to further strengthen the connection between the ceiling wall a ₃ and the bottom wall a ₁ to the side peripheral wall a ₂ .

In addition, the outer support post D has a mounting plate 36 fixed to the lower end by means such as welding, and is fixed to the pedestal B.
At the upper end, there is a mounting plate 36 similarly fixed to the upper end, and bolts and nuts 37 on the upper surface of the ceiling wall _A3 .
38 is fixed by connecting it to the reinforcing plate 39 which is fixed.

Further, 40 is a turnbuckle type auxiliary diagonal stay, which includes a stay bracket 41 on the inner surface of the cross-shaped joint Y on the side peripheral wall, and the above-mentioned stay brackets ₁ , 1 fixed on the inner surface of the cross-shaped joint X on the bottom wall a1.
The stay mounting pieces 9, 9, 15, and 15 are diagonally installed at an angle of 45 degrees.

By the way, this example shows an assembled water tank A with a total height of 2.5 m, so the general panel 23-2
are arranged in a row at the bottom, but for example, the total height is 3.5
When constructing an assembled aquarium A with a length of 23 m or more, all the lower stages of the long panel 23-1 row are replaced with the general panel 23.
Needless to say, it consists of -2. Alternatively, an assembled water tank A may be used in which the side peripheral wall _a2 is assembled and formed using only the general panel 23-2.

[Effect of idea]

Since the present invention is constructed as described above, the stay bracket can be connected to the pedestal by simply drilling a mounting hole in the protruding portion of the pedestal of the metal reinforcing connecting body that protrudes left and right from the steel frame.

Therefore, unlike the prior art in which the first, second, third, and fourth mounting holes of the first and second brackets are used to fix the panel to the joint flange of the panel or the frame, and the bolts are screwed into the high nuts, each Connection will not be impossible due to dimensional errors in the hole drilling position, and since there are no mounting holes drilled in the pedestal, there will be no reduction in the strength of the pedestal.
Of course, since there is no error in assembling the pedestal, the connection of the stay bracket to the pedestal is reliable. Moreover, since the metal reinforcing connecting body only needs to be brought into contact with the lower surface of the steel mold that constitutes the pedestal when connecting the stable bracket to the pedestal, the first
There is no need to fix the second bracket to the joining flange of the panel or the frame, making the connection work much easier.
