DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will now be described with reference to FIGS.
A description will be given based on FIG. As shown in FIG. 3, the tank 1 for storing liquid (water) is configured by, for example, joining a plurality of metal (for example, aluminum) panels to each other. That is, the tank 1 includes a bottom wall panel (not shown), four lower side wall panels 2 erected vertically upward from each side of the bottom wall panel, and four lower side wall panels provided above these. An upper side wall panel 3 and a top wall panel (not shown) mounted in a lid shape on the upper side of the upper side wall panel 3. Each of the panels 2 and 3 constitutes a plate-like body in this embodiment.
The panels 2 and 3 have convex portions 2a and 3a which bulge outward in order to impart predetermined strength and rigidity to the entire tank 1.
Are formed. Further, a water supply port (not shown) is provided at an upper portion of one upper side wall panel 2, and a water outlet (not shown) is provided at a bottom wall panel. With this configuration, supply, storage, and discharge of water can be performed in the tank 1.

Next, the joining structure of the panels 2 and 3 in this embodiment will be described. In this embodiment, the adjacent panels are at an angle of 90 °, that is, the vertically joined portion (eg, α portion in FIG. 3) and the adjacent panels are at an angle of 180 °, There are portions that are joined in parallel (for example, the β portion in FIG. 3).

FIG. 1 is a sectional view showing the portion α in FIG.
The two upper side wall panels 3 (hereinafter referred to as 3A and 3B for convenience) are vertically joined. Each panel 3A, 3B
Is provided with panel main bodies 4A and 4B and flanges 5A and 5B provided on side edges thereof. Panel body 4A,
At the side edges of 4B, bent portions 6A and 6B formed by bending 45 ° inward are formed. In addition, flange 5
A and 5B are attached by welding in a state where they are in contact with the bent portions 6A and 6B. A plurality of through holes 8A, 8B are formed in the flanges 5A, 5B along the longitudinal direction.

As shown in FIG. 4, both panels 3A, 3A
A rubber packing 9 as an elastic body is interposed between the flanges 5A and 5B of B. In the flanges 5A and 5B arranged opposite to each other, bolts 10 constituting fastening means are inserted into the through holes 8A and 8B, and are tightened together with nuts 11 which also constitute fastening means. It is fixed by the thing. In addition, between the head of the bolt 10 and the flange 5B, and between the flange 5A and the nut 1A.
Washers 16 are respectively interposed between the first and second washers.

FIG. 2 is a sectional view showing a portion β in FIG. As shown in the figure, the lower side wall panel 2 and the upper side wall panel 3A are joined in parallel. At the lower edge of the panel body 4A of the upper side wall panel 3A, 9
A bent portion 7 formed by bending at 0 ° is formed.
The bent portion 7 has a flange 5C having a through hole 8C.
Are attached by welding in a state of surface contact. Similarly, the lower side wall panel 2 includes a panel body 12 and a flange 13. At the side edge of the panel body 12, a bent portion (not shown) formed by being bent at an inside of 45 ° is formed. In addition, a bent portion 14 is formed at the upper end edge of the panel main body 12 by being bent inward by 90 °. The flange 13 is attached by welding in a state where the flange 13 is in surface contact with the bent portion 14, and has a through hole 15.

The two panels 2 and 3A also have the two flanges 13 and 5.
Both flanges 13 and 5C are fitted to each other via a packing 9 between C so as to face each other. The flanges 13 and 5C are fastened and fixed by the bolt 10 and the nut 11 in a state where the bolt 10 is inserted through the through holes 15 and 8C and a state where the washer 16 is interposed at a predetermined position. .

Next, the operation and effect of this embodiment will be described. In the tank 1 configured as described above, each edge portion of the panels 2, 3A, 3B, that is, each bent portion 6A, 6B, 7, 1 of the panel main bodies 4A, 4B, 12 is used.
Reference numeral 4 denotes flanges 5A, 5A having predetermined angles (45 °, 90 °) with respect to the surfaces of the panel bodies 4A, 4B, 12.
B, 5C, 13 are provided, and the flanges 5A, 5C are provided.
B, 5C, 13 are fastened and fixed to each other by a bolt 10 and a nut 11 via a packing 9. At this time, the gap between the panels 2, 3A, 3B is closed due to the contraction of the packing 9 due to the fastening of the bolt 10 and the nut 11, and the stored water does not leak. Therefore, even if the configuration as in the present embodiment is adopted, it is possible to prevent the storage performance from deteriorating.

When manufacturing the tank 1, the flanges 5A, 5A provided on the respective edges of the panels 2, 3A, 3B are provided.
What is necessary is just to fasten 5B, 5C, 13 with the bolt 10 and the nut 11, and easily and reliably the panels 2, 3A, 13B.
3B can be joined. That is, unlike the related art in which welding is performed, workability can be significantly simplified.

Further, when an attempt is made to install a relatively large tank 1, the panel 2 is installed up to the installation location.
It is necessary to carry 3A, 3B, etc., and assemble and join them on site. Even in such a case, according to the present embodiment, the tank 1 can be easily assembled and manufactured without dispatching a skilled worker. Therefore, the cost required for manufacturing can be reduced, and as a result, the workability can be significantly improved.

In addition, according to the present embodiment, unlike the prior art, when the welded portion is damaged due to aging or the like, welding work or the like must be performed again.
Repair can be performed only by retightening the 0 and the nut 11 and replacing the packing 9. As a result, maintenance performance can be significantly improved.

In addition, in this embodiment, the panel body 4
Flanges 5A, 5B, 5 having a symmetrical angle of 45 ° or 90 ° with respect to the planes of A, 4B, 12
C and 13 were provided. Therefore, panels 2 and 3
A and 3B have compatibility, and mass production is possible. As a result, the cost can be further reduced.

The present invention is not limited to the above-described embodiment, and may be configured as follows, for example. (1) In the above embodiment, the bolt 10 and the nut 11 are employed as the fastening means. However, as shown in FIG. 5, for example, a female screw 21a is formed in one through hole 21 and the screw 22 is formed therein. It may be configured to be fastened, and this may be used as fastening means. Further, as shown in FIG. 6, a configuration may be adopted in which a rivet 25 as a fastening means is inserted through the through holes 23 and 24 and fastened and fixed therewith.

(2) In the above embodiment, the packing 9 having a rectangular cross section is used as the elastic body. However, the cross sectional shape is not limited at all. For example, as shown in FIG. The packing 26 in the form of an iron array may be used, or the packing 27 having an uneven portion 27a may be used as shown in FIG. 7B. With this configuration, it is possible to further improve the sealing performance. In addition, the material of the elastic body is not limited to rubber, but may be any resin such as a resin having a predetermined elasticity as long as it can be contracted by a predetermined amount by tightening and can secure a sealing property between adjacent panels. May be used.
