Description

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

Recently, large containers such as tanks are often assembled from a large number of unit plates. Various types of unit boards are known, but a typical one is one in which a right-angled rectangular board is provided with a joining edge protruding toward the same side at its periphery. The bonding edge here includes an upright bonding edge that stands upright at an angle of approximately 90 degrees to the substrate, and an upright bonding edge that is approximately 135 degrees to the substrate.
Beveled joint edges that are beveled at an angle of .degree. Furthermore, unit plates are known that include only one of an upright joint edge or an inclined joint edge along the four sides of the substrate, and those that include both.

When assembling one side wall, bottom, or lid using the above-mentioned unit plates, the upright joining edges of the plurality of unit plates were brought into contact with each other, and the unit plates were connected in the same plane. Moreover, the tank thus assembled was placed on a horizontal installation surface. However, when the tank assembled as described above is placed on a horizontal installation surface, the bottom or the lid becomes horizontal as a whole, resulting in poor drainage.

As one method to eliminate this drawback, it has been proposed to slope the bottom or lid using something like a footplate. In this case, if the bottom or the lid were tilted only in one direction, the balance would be poor and the structure would be vulnerable to earthquakes, so it was considered preferable to have the bottom slope in a concave position and the lid slope in a central position. When the bottom or the lid is tilted as described above, the unit plates are connected in a bent direction at the point where the tilt direction changes. However, since the upright joint edge is supposed to stand upright at an angle of approximately 90 degrees to the board, if you try to connect the unit plates in a bent direction, strain will be applied to the upright joint edge and the unit plate will be destroyed. There was a drawback. This invention was made in an attempt to improve the above-mentioned drawbacks.

This idea uses a shallow box-like body with an upright joining edge protruding to the same side on the periphery of a right-angled board as a unit plate, and in order to connect multiple unit plates in an inclined state, the longitudinal part is used as a packing. The main idea is to use one in which the thickness of one side edge along the direction is thicker than the thickness of the other side edge.

It is already known to use a tape whose thickness on one side along the longitudinal direction is larger than the thickness on the other side as a packing. That was in 1974.
It is described in Publication No. 107212. However, Mikiakiaki
In the tape-shaped packing described in Publication No. 54-107212, the upright joining edge of the unit plate is not oriented perpendicularly to the substrate for molding reasons, so a wall thickness difference is required to correct this error. It's just that. Therefore, the difference in wall thickness is extremely small. In addition, Utility Model Application Publication No. 54-107212 only teaches how to properly maintain the plane or right angle between the substrates of adjacent unit plates, but does not teach how to maintain the plane or right angle between the substrates of adjacent unit plates. It is not intended to teach. However, in this invention, in order to maintain a non-perpendicular and non-flat angle between the substrates of adjacent unit boards,
A tape-like packing with different wall thicknesses is used.

This device uses a shallow box-like body with an upright joining edge protruding to the same side on the periphery of a rectangular four-shaped substrate as a unit plate, and arranges multiple unit plates in the same plane or in a crosswise manner to form adjacent units. A strip is sandwiched between the abutting parts of the plates, one edge along the length of the strip is thicker than the other edge, and the abutting parts are joined to form adjacent units. This invention relates to an assembled tank in which the substrates of the plates are connected at non-perpendicular and non-flat angles, thereby forming an inclined surface.

The assembled tank according to this invention will be explained as follows based on the drawings. 1 and 2 are partially cutaway perspective views showing an example of an assembled tank according to this invention. 3 to 5 are partially cutaway perspective views showing an example of unit plates used in this invention. 6 to 8 are partially cutaway perspective views showing an example of a strip used in this invention, and FIG. 9 is a partially cutaway vertical sectional view of another assembled tank according to this invention.

In FIG. 1, a tank is assembled from unit plates 1A. The unit plate 1A has a right-angled joining edge 12 on the periphery of a right-angled rectangular substrate 11 that protrudes toward the same side. The upright joining edges 12 of the plurality of unit plates 1A are fixed to each other to form a bottom, a lid, and a side wall.

At the bottom of the tank, a strip 2A is sandwiched between the upright joining edges 12 of two unit plates 1A. Strip 2
In A, one side edge 21 along the longitudinal direction is thicker than the other side edge 22. The one side edge of the strip 2A is directed downward, and the upright joint edges 12 are abutted on both sides, and are fixed with bolts (not shown). As a result, the two unit plates 1A are connected in an upwardly bent direction with the strip 2A as a boundary.

In the tank lid, the strip 2A is also sandwiched between the right-angled joint edges 12 of the two unit plates 1A.
In this case, one side edge 21 of the strip 2A is directed upward and fixed as before. the result,
The two unit plates 1A are connected in a downwardly bent direction with the strip 2A as a boundary. What is constructed in this way is the assembled tank according to this invention.

In the above assembly tank, the unit plate 1A is made of metal (for example, iron) or reinforced synthetic resin (for example, glass fiber reinforced polyester resin). The substrate 11 can include a heat insulating material to form a sandwich structure. Further, the substrate 11 can be provided with various irregularities.

The strip 2A is made of a flexible material (for example, rubber, soft resin, or a foam thereof) or a hard material (for example, hard resin). When the strip 2A is made of a hard material, it is desirable to abut soft tape-like packing on both sides thereof. Strip 2A
In this case, the intersection angle θ of the straight line connecting both ends of the thickness of one side edge 21 and the other side edge 22 is suitably about 1.5 to 30 degrees, preferably about 2 to 10 degrees. Further, it is desirable that the strip 2A has a constant thickness along the longitudinal direction.

In addition, between each upright joint edge that does not sandwich a strip,
It is desirable to sandwich tape-like packing. A beam 3 is provided on the lower side of the lid, and the beam 3 can be supported by a pillar 4. Further, a foot peg 5 can be attached to the bottom constituent unit plate.

What is shown in FIG. 1 is one of the basic embodiments of the assembled tank according to this invention. This idea also includes some modifications.

For example, in the assembled tank according to this invention shown in FIG. 2, strips 2A are attached along two opposite sides of one bottom component plate 1A or one lid component plate 1A. As a result, the bottom and lid are bent in two places. In FIG. 2, the beam 3 is stretched horizontally, and the spacer 6 is inserted between the beam 3 and the lid. Further, the bottom is placed on a pedestal 7 having an inclined upper surface.

Furthermore, in the assembled tank shown in FIG. 1 or 2, unit plates 1B to 1D shown in FIGS. 3 to 5 can be used instead of unit plate 1A.

The unit plate 1B shown in FIG.
In the unit board 1A shown in the figure, a bulge 13 is provided in the center of the substrate 11.

The unit plate 1C shown in FIG.
In the unit board 1A shown in the figure, the substrate 11 as a whole is bulged toward the side where the upright joining edge 12 does not exist.

The unit plate 1D shown in FIG.
In the illustrated unit board 1A, an inclined joint edge 14 inclined at an angle of 135 degrees with respect to the substrate 11 is provided between the substrate 11 and the upright joint edge 12.

In addition, a unit plate in which the substrate 11 is provided with protrusions in a cross shape, an X shape, etc. can be used.

Furthermore, in the assembled tank shown in FIG. 1 or 2, the strips 2B to 2D shown in FIGS. 6 to 8 can be used instead of the strip 2A.

The strip 2B shown in FIG.
Although it has almost the same appearance as the strip 2A shown in the figure, it is different in that it is not made integrally but by bonding two thin pieces 23 together. thin section 2
3, one side edge 21 side is thicker than the other side edge 22 side.

The strip 2C shown in FIG. 7 is made by pasting together three thin pieces. Among them, thin pieces 2 on both sides
3 is the same as the thin piece shown in FIG. 6, and the central thin piece 24 has a constant thickness.

The belt-shaped object 2D shown in FIG.
In the strip 2A shown in the figure, the ampulla 2 along one side edge.
5. This enlarged portion 25 is intended to be secured to the upper end of the upright joint edge without being sandwiched between the upright joint edges.

In FIG. 9, the tank is assembled with unit plates 1A and 1E. A partition wall 8 is attached inside this tank, and the partition wall 8 is also composed of unit plates 1A. In this tank, the strip 2A is used not only to construct and attach the lid of the tank, but also to connect the inclined substrate of the bottom unit plate 1E to the interval 8.

The assembled tank according to this invention is a tank in which unit plates each having an upright joint edge are connected to the periphery of a base plate, and a strip is sandwiched between the upright joint edges, and one side edge along the longitudinal direction of the strip is connected to the other side. Since it is made thicker and the upright joint edges are brought into contact with both sides of the strip, it is easy to connect the unit plates in the direction of bending with the strip as a boundary. Further, when the unit plates are connected in a bent direction, no strain is caused on the upright joint edges. Therefore, according to this invention, tanks with bent bottoms, lids or side walls, as well as partition walls and side walls on sloping bottoms, can be easily made. This invention has excellent advantages as mentioned above.
