Description

[Detailed description of the invention] This invention relates to a reinforcing unit plate for tank assembly.

It has already been practiced to assemble large containers such as tanks from shallow box-like unit plates in the shape of a right-angled quadrilateral.

Such unit plates include one in which upright joining edges projecting to the same side are provided on the four peripheries of a right-angled rectangular substrate (Utility Model Publication No. 40-27399), and in the above-mentioned unit plates,
A device in which an inclined bonding edge is provided between the substrate and the upright bonding edge (Japanese Utility Model Publication No. 49-59106) is often used.

However, when a large-capacity tank is assembled using the unit plates described above, there is a drawback that when the tank is filled with liquid, the side wall of the tank bends to open outward.

As one method for preventing the above-mentioned deflection, an attempt has been made to extend a stay between the opposing side walls to maintain a constant distance between the side walls.

In this method, when the stay is fixed to the bottom of the side wall,
The stays were an obstacle when walking inside the tank to clean or inspect the tank, so they were fixed to the top of the side wall.

However, the hydraulic pressure applied to the side wall is greater at the lower part, so if the stay is fixed to the upper part of the side wall, a large force will be applied to the unit plate that makes up the lower part, causing the unit plate to bow and eventually break. occurred.

In order to prevent this drawback, there is no other suitable method other than increasing the strength of the unit plate itself.

Therefore, in the past, several types of unit plates were made that differed only in wall thickness, and unit plates were used that became thicker toward the bottom of the side wall.

However, in this case, it is necessary to always prepare several types of unit plates that differ only in wall thickness, which has the disadvantage of requiring additional costs in terms of manufacturing, storage, etc.

This inventor thought to improve the above-mentioned drawbacks.

Then, instead of changing the wall thickness of the unit plates, we considered attaching a reinforcing plate to the unit plates.

As the reinforcing plate, a bent plate consisting of one piece parallel to the substrate of the unit plate and two pieces parallel to the two joint edges that intersect with each other at the corner of the substrate is used. An attempt was made to abut at least two adjacent corners located on the lower side of the constituent unit plates.

As a result, it was confirmed that by doing so, destruction of the unit plate could be prevented.

In addition, it was confirmed that it is more convenient for storage, use, etc. to make a bending plate separately for each corner, rather than making one that spans two adjacent corners.

This idea was made based on such confirmation.

That is, this invention is a shallow box-shaped body formed by providing joint edges protruding to the same side on the four peripheries of a right-angled substrate.
A bending plate is provided inside the box, and the bending plate has one piece parallel to the board and two pieces parallel to the two joining edges that intersect with each other at the corner of the board.
The tank is constructed by integrally connecting two pieces, the one piece and the two pieces are in contact with the substrate and the joint edge, respectively, and such bent plates are separately present at at least two adjacent corners of the box-like body. This is a reinforcing unit plate for assembly.

The reinforcing unit plate for tank assembly according to this invention will be explained as follows based on the drawings.

In FIGS. 1 and 2, upright joint edges 12 projecting to the same side are attached to the four peripheries of a right-angled substrate 11 to form a shallow box-shaped body 1A.

In this box-like body, a bending plate 2A is provided inside the box.

The bent plate 2A has one piece 21 parallel to the substrate 11 and two pieces 2 parallel to two upright joining edges 12 that intersect with each other at the corners of the substrate.
2 are integrally connected.

The one piece 21 and the two pieces 22 abut against the substrate 11 and the upright joint edge 12, respectively.

Such bending plates 2A are provided separately at two adjacent corners of the box-like body.

What is constructed in this way is the reinforcing unit plate a for tank assembly according to this invention.

Furthermore, it is desirable that the edge 213 be located between the two arcs X and y, as shown in FIG.

The above-mentioned circular arc .

The arc y is centered on a point W that bisects the angle U and the center V of the substrate 11, and has a radius equal to 1/4 of one side of the substrate 11. This is the part rolled up between the two upright joining edges 12 as in the case of .

The edge 213 may be a broken line as shown, or may be a straight line or a curve.

It is desirable that one piece 21 covers the corner of the substrate 11 .

Note that the portion along the edge 213 may be bent toward the protruding side of the two pieces 22.

The two pieces 22 of the bending plate 2A are the two edges 2 of the one piece 21 mentioned above.
11,212.

It is desirable that the two pieces 22 have the same length as the edges 211 and 212.

The bending plate 2A can be made of metal or synthetic resin like the box-shaped body 1A, but it is preferable that the bending plate is stronger than the box-shaped body 1A.

That is, when the box-like body 1A is made of metal, the bending plate 2
A is made of metal that is thicker than box-shaped body 1A, and box-shaped body 1
When A is a synthetic resin, it is desirable that the bending plate 2A be made of metal or a synthetic resin that is thicker than the box-shaped body 1A.

The opposing ends of the two bending plates 2A may be in contact with each other, or may be separated from each other.

The bending plate 2A can be welded or bonded to the box-shaped body 1A.

Furthermore, when joining the unit plates together, they can also be fixed in alignment with bolts.

Note that it is desirable that bolt insertion holes be drilled in advance in the box-like body and the bending plate.
