Description

[Detailed description of the invention] This invention relates to an improvement of an assembled tank.

In recent years, large containers such as tanks are often assembled from a large number of unit plates. Various types of unit boards are known, but the most typical one is a shallow box-shaped board with joint edges protruding to the same side on all four sides of a right-angled board. It is. When assembling a tank using the above-mentioned unit plates, the unit plates are arranged on the same plane or in orthogonal directions to form the bottom, side walls, partition walls, etc.

In a tank assembled in this way, a liquid such as water is introduced from the inlet and supplied to the point of use from the outlet, but since the liquid tends to flow along a straight line connecting the inlet and outlet, Positions far away from the straight line result in little liquid movement, resulting in so-called dead water. Therefore, in order to prevent this drawback, a standing plate is installed along the vertical plane that divides the inside of the tank into two, and a part of the vertical plane is opened to create a liquid passage, and such a standing plate is used to regulate the flow of liquid. The practice is to allow the liquid to flow evenly into the tank. This standing board is also called a rectifying wall.

The above-mentioned upright plate does not receive hydraulic pressure from one side, so it does not flex significantly, but it does flex to some extent due to the flow of liquid, so it was necessary to prevent this flexing. On the other hand, in order to prevent warping of tank walls that receive hydraulic pressure from one side, such as side walls or partition walls, mutually opposing or orthogonal walls are supported by stays. To fix the end of this stay to the tank wall, use a stay lock consisting of a vertical piece on one side of a small plate, fix the small plate of the stay lock to the tank wall, and fix the end of the stay to the vertical piece. It was done. However, when such stays are newly attached to the above-mentioned upright plate, there is a problem that the number of stays becomes too large, and the stays become complicated in the tank, which becomes an obstacle for inspection, cleaning, etc.

The inventor attempted to use the stays that support the side walls or partition walls as they are to prevent the above-mentioned standing boards from bending. Then, a notch is provided on the side edge or lower edge of the upright board, a stay lock is fitted into the notch, and the upright piece is positioned on the joint of the unit board,
It has been found that extending the stay parallel to the upright board will help prevent the upright board from bending because the stay will come into contact with or extend near the upright board. The idea was made based on such knowledge.

In other words, this invention uses a shallow box-like body formed by providing joint edges protruding to the same side on the four peripheries of a right-angled substrate as a unit plate, and connects a large number of unit plates in the same plane and in orthogonal directions. make up the tank wall,
In a tank where a standing plate is provided along a vertical plane that bisects the inside of the tank, a part of the vertical plane is opened to create a liquid passage, and the side edge or lower edge of the standing plate is fixed along the tank wall, the above A portion of the side edge or lower edge is cut out, a stay lock is provided in the cutout, and the stay lock is a vertical piece provided on one side of the small plate.
Position the vertical piece on the extension of the vertical plate, fix the small plate to the unit plate, fix one end of the stay to the vertical piece,
This is an assembled tank in which the stay extends parallel to the upright plate, and the other end is fixed on the tank wall at right angles or on the opposite side.

The assembled tank according to this invention will be explained as follows based on the drawings. 1 to 4 are partially cutaway perspective views showing an example of an assembled tank according to this invention. FIG. 5 is a vertical sectional view showing another example of the assembled tank according to the invention.

In FIG. 1, the side walls and bottom of the tank are assembled from unit plates 1a. The unit plate 1a is a shallow box-shaped body in which upright joining edges 12 that stand upright with respect to the substrate 11 are provided around the four peripheries of a right-angled substrate 11. The unit plate 1a has an upright joint edge 12 directed outward and adjacent to the bottom and side walls in the same plane and orthogonal direction. A standing board 2 is provided along a vertical plane at a position that bisects the inside of the tank. A part of the vertical surface is left open by omitting the upright plate 2 and becomes a liquid passage 3. A side edge 21 of the standing board 2 is fixed along the side wall, and a lower edge 22 is fixed along the bottom.

In this tank, a side edge 21 and a lower edge 22 of the upright plate 2 are partially cut out, and a stay lock 4 is provided in each cutout 23. The stay lock 4 is provided with a vertical piece 42 on one side of a small plate 41, and with the vertical piece 42 located on an extension of the vertical piece 2, the small plate 41 comes into contact with the base plate 11 of the unit plate 1a. and fixed. One end and the other end of the stay 5 are fixed to the vertical pieces 42 of the two stay locks 4, respectively. The stay 5 extends parallel to the upright plate 2. What is constructed in this way is the assembled tank according to this invention.

In the above tank, the unit plate 1a is made of metal (for example, iron) or reinforced synthetic resin (for example, glass fiber reinforced polyester resin). Board 1
1 can be provided with large-sized unevenness such as circular, square, octagonal, cross-shaped, x-shaped, etc. or a large number of small unevenness. Further, the substrate 11 may include a heat-insulating material layer (for example, a hard resin foam).
The tank lid is assembled from unit plates 1b. The unit plate 1b has a substrate 1 in the unit plate 1a.
1 as a whole is bulged toward the non-projecting side of the upright joint edge. The bulging shape is preferably a truncated quadrangular pyramid.

The upright board 2 is made of the same material as the unit board 1a, but can be made thinner than the unit board. The standing board 2 may be a single large board, or may be a piece of joined material. When fixing the side edge or lower edge of the standing board 2,
It is desirable that the side edges or lower edges be along the joints of the unit plates 1a. Further, in this case, it is convenient to use a fixture 24 bent in an L-shape. Incidentally, by supporting the upper part of the standing board 2 with a rod 25, it is possible to prevent the standing board from tilting.

The stay lock 4 is mainly made of metal. There may be some gap between the vertical piece 42 and the edge of the notch 23 of the vertical plate. It is desirable that the small plates 41 be fixed across the joints between the unit plates 1a. It is appropriate for each of the above-mentioned fixings to be performed using bolts. The stay lock 5 is also mainly made of metal. The stay 5 may be provided only on one side of the upright board 2, or may be provided on both sides. When provided only on one side, it is preferably provided on the outlet side of the tank.
Note that, as shown in the drawings, stay locks and stays other than those described above can be provided, and the stays can also be passed through the upright plate 2.

One representative embodiment of the present invention is shown in Figure 1. The present invention also includes slight modifications thereto, as described below.

FIG. 2 shows that the upright board 2 may be spliced along a vertically extending seam and that the free side edge of the upright board 2 may be fixed to the column 6. The stay lock is composed of two small angular pieces, one of which is stacked on top of the other and fixed by bolts or welding to form a vertical piece 42, and the other is arranged on the same plane as a small plate 41. This indicates that you may use the Furthermore, it is shown that the stay 5 may be fixed to the upright plate 2 with something like a bolt.

FIG. 3 shows that the upright boards 2 may be joined along joints extending in the vertical and horizontal directions;
In addition, it is shown that a joint extending in the vertical direction may be joined via a column 6. It is desirable that the vertical plates 2 adjacent to each other via the pillars 6 are connected by a strip plate 26. In addition, at the seam extending in the horizontal direction, an elongated body 7 having an H-shaped cross section is interposed,
It is desirable to insert the edge of the upright board into the recess of H. Furthermore, in this figure, the side edge 21 of the standing board
is fixed to the partition wall. In this case, as illustrated, the side edge 21 may be placed along the joint of the unit plate 1a from the side from which the upright joining edge 12 projects. Furthermore, a reinforcing angle 27 can be fixed to the upper end of the standing board.

Figure 4 shows that the side wall and bottom of the tank are unit plate 1e.
This indicates that it may be assembled from The unit plate 1e is arranged around the four peripheries of the substrate 11, with respect to the substrate 11.
Provided with an inclined joint edge 13 inclined at an angle of 135 degrees,
An upright joining edge 12 is provided at the tip. Further, the upright board 2 may be provided with unevenness similar to that of the unit board 1e, and the side edges 21 and lower edges 22 of the upright board 2 are formed by opposing inclined joint edges 13 of the unit board 1e. It shows that it may be fixed by being inserted into a V-shaped groove, and that the upper edge of the upright plate 2 may be fixed to the beam 8 by a connector 81 depending from the beam 8. Furthermore, standing board 2
It is shown that the and stay lock 4 may be fixed by a connecting tool 43. Also, this diagram
An example is shown in which two stays 5 are provided in parallel on both sides of the standing board 2.

FIG. 5 shows that both side edges 21 and 28 of the upright plate 2 are fixed to the side walls, and a liquid passage 3 is provided between the lower edge 22 and the bottom.
This indicates that it may be provided. It also shows that the stay locks 4 provided on both sides of the partition wall may be fixed to each other with long bolts.

In this device, the assembled tank has a tank wall made up of unit plates, a standing plate is provided along a vertical plane that bisects the inside of the tank, and the side edge or lower edge of the standing plate is fixed along the tank wall. In the tank, a part of the side edge or the lower edge is cut out and a stay lock is provided in the cutout, so that the upright piece of the stay lock can be positioned on an extension of the upright plate. Since one end of the stay is fixed to the upright piece located on the extension of the upright board and the stay is extended parallel to the upright board, the stay extends in contact with or close to the upright board. Therefore, the stay prevents the standing board from bending, and the standing board is reinforced. Furthermore, since the other end of the stay is fixed on the perpendicular or opposing tank wall, the stay reinforces the tank body. The great advantage of this invention is that the stay plays a dual role in this way.

Further, according to this invention, since the stay lock is accommodated in the notch of the upright plate, it is possible to easily attach the other stay to an existing tank that is provided with only one of the stays. Moreover, since the assembled tank according to this invention has a simple structure, it can be supplied at low cost. Therefore, the assembled tank of this invention has great practical value.
