Description

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

For large containers such as tanks, instead of building them all in one piece from the beginning, it is better to make them separately into unit plates, transport these unit plates to the installation site, and assemble them together at the installation site. is convenient. One of the above-mentioned attempts is described in Utility Model Publication No. 40-27399. According to this publication, a unit plate is a right-angled flat plate with a connecting edge that stands upright on the peripheral edge of the flat plate, and the connecting edge of this unit plate is connected outward and connected to the bottom of the tank. The side walls are assembled. However, when assembling the bottom of a tank with the connecting edges facing outward, first arrange the connecting edges of the unit plates in the same plane with the connecting edges facing upward, then connect the adjacent connecting edges to each other, and then This required the complicated and dangerous process of turning it upside down with the connecting edge facing down. Therefore, it was considered to create a tank in which the connecting edge is located inside the tank. However, if the connecting edge is placed inside the tank, at the bottom of the tank,
Since the connecting edge projects upwards, the disadvantage arises that the tank is incompletely drained. In order to eliminate the above-mentioned drawbacks, the inventors combined a large number of rectangular unit plates with concave portions provided at the corners and liquid passages provided at the connection edges around the concave portions 15. I first proposed making the bottom of the tank (Japanese Patent Application No. 119957/1982). However, although this proposal is suitable for making a rectangular parallelepiped-shaped tank, it is not suitable for making a tank other than a rectangular parallelepiped, such as a cylindrical one. The present invention provides a tank of any shape that has good drainage and has an internal bottom. That is, the present invention provides a tank comprising a side wall unit plate 25 erected on the periphery of a bottom assembled by joining a plurality of unit plates, wherein at least one of the unit plates constituting the bottom is A plane other than a right-angled quadrilateral is used as a substrate, and the rest is a right-angled quadrilateral or a plane other than a right-angled quadrilateral is used as a substrate, a connecting edge is provided on the periphery of each substrate to form a box-shaped body, and the bottom of the box-shaped body is At least 90 of the corners are bent in a direction opposite to the direction in which the connecting edge is attached to form a recessed portion, the connecting edge is made upright with respect to the original plane, and a liquid passage is provided at the connecting edge around the periphery of the recessed portion. This tank is characterized in that the connecting edges of these unit plates are brought into contact with each other and combined to form a bottom.

The tank of the present invention will be explained as follows based on the drawings.

FIG. 1 is a partially cutaway perspective view showing an example of a tank according to the present invention.

FIG. 2 is a perspective view showing an example of a combination of a unit plate and an angular piece used at the periphery of the bottom in the tank of the present invention. 3 and 4 are partially cutaway perspective views showing another example of the tank of the present invention, respectively. Fifth
FIG. 6 is a partial sectional view showing an example of a tank according to the present invention installed on a pedestal. 7th
8, 9, 10, and 11 are partially cutaway plan views showing still another example of the tank of the present invention. In FIG. 1, the tank of the present invention has unit plates for side walls erected around the periphery of a bottom assembled by joining a plurality of unit plates, and all of the unit plates constituting the bottom are The substrate is a plane other than a right-angled quadrilateral.

That is, the bottom of the tank includes a unit plate 1A1 having a fan-shaped plane as a substrate, a unit plate 2A having a fan-shaped plane as a substrate,
It is composed of 2B, 2C, 2D, 2E, and 2F. The unit board 1A has a connecting edge 12 on the periphery of a fan-shaped substrate 11 to form a box-like body, and two of the bottom corners of the box-like body are arranged in a direction opposite to the direction in which the connecting edge 12 is provided. bent into a concave part 1
3, the connecting edge 12 is made to stand upright with respect to the original plane 11, and the connecting edge 12 at the periphery of the concave portion 13 is cut out in the shape of a circular hole to provide a liquid passage 14.

The unit board 2A has a connection edge 2 on the periphery of the fan-shaped board 21.
2 to form a box-shaped body, and two of the corners of the bottom of the box-shaped body are bent in the direction opposite to the direction in which the connecting edge 22 is attached to form a recessed part 23, and the connecting edge 22 is bent to form a box-shaped body. The connecting edge 22 at the periphery of the concave portion 23 is cut out in the shape of a circular hole to provide a liquid passage 24.

The unit plate 2B is substantially the same as the unit plate 2A, but differs in the position where the recessed portion 23 is provided.

The unit plates 2C and 2D are almost the same as the unit plates 2A and 2B, but the radius of the arc of the arcuate side is large, and the concave portion 2
3 is provided in three locations. Unit plates 2E and 2F are substantially similar to unit plates 2A and 2B, but the radius of the arc of the arcuate side is larger than that of 2C and 2D, and a concave portion 23 is provided at one location. The connecting edges of these unit plates are brought into contact with each other and connected at ports 3 to form the bottom.

The liquid passages 14 or 24 provided in the concave portions 13 or 23 of each unit plate communicate with the liquid passages 14 or 24 of adjacent unit plates. 1 of the unit plates that make up the bottom
A drain hole 4 is provided at the bottom. Around the bottom,
The angular piece 5A is combined, and the side wall unit plate 6 is placed on top of the angular piece 5A.
A is connected. In this way, the tank is assembled. In the above unit plates 1A1 and 2A to 2F, the substrates 11 and 21 include, for decoration or reinforcement,
A protruding pattern such as an x-shape, cross-shape, star-shape, or circle can be provided.

Further, the entire substrates 11 and 21 can be bulged upward to form a pyramidal surface or a truncated pyramidal surface. Furthermore, in the unit plates 1A and 2A to 2F, the liquid passage may be provided by notching the upper end of the connecting edge, instead of boring the circular hole in the connecting edge described above.

In either case, the deepest end of the circular hole or notch is located on the back side of the original plane. In the unit plates 2E and 2F used at the periphery of the tank bottom, as shown in FIG. 1, it is normal to provide the concave portion 23 at the end of the small inner arcuate side, but as shown in FIG. It may be provided at the end of the large inner arcuate side like the unit plate 2G.

In this case, both ends 51 of the curved surface of the angled piece 5B are made large enough to close the liquid passage 24. What is shown in FIG. 1 is one basic form of the tank of the present invention.

This invention includes various modifications thereof. For example, in the tank shown in FIG. 3, the unit plate used at the periphery of the bottom of the tank is different from that in FIG. In the unit plates 2H and 2K used in FIG. 3, the tip 25 of the connecting edge 22 provided on the large inner arcuate side is
It differs from unit plates 2E and 2F in FIG. 1 in that it is bent outward parallel to the original plane. By using unit plates 2H and 2K, side wall unit plates 6B can be connected without using angles. In addition, in the unit plates 2H and 2K, the substrate 21 may be extended below the tip 25 of the bent connecting edge. Furthermore, in the tank shown in FIG. 4, other unit plates 2L and 2M are used around the periphery of the tank bottom.

In the unit plates 2L and 2M, the tip 26 of the connecting edge 22 provided on the large inner arcuate side is bent inward parallel to the original plane. By using unit plates 2L and 2M, side wall unit plates 60 can be connected without using angles. In addition, in the unit plates 2L and 2M, a supporting wall may be provided between the substrate 21 and the tip of the connecting edge. Furthermore, since the side wall unit plates used in FIG. 3 have curved left and right connecting edges 61, they can be connected at any angle. It is convenient to install these tanks on a shaped steel pedestal 7A1 shown in FIG. 5 or a concrete pedestal 7B shown in FIG.

In the tank of the present invention, since the bottom is assembled using an internal assembly method, there is no need to provide an inspection passage under the tank, and a relatively low mount is sufficient. In addition, FIG. 6 shows an example of a tank whose bottom is assembled with a unit plate 2N in which a liquid passage 24 is provided by cutting out the upper end of the connecting edge. Figures 1 and 3 above
Although the tanks shown in the figures and FIG. 4 are both cylindrical, the tank of the present invention is not limited to the cylindrical shape. In addition, in the tanks shown in FIGS. 1, 3, and 4, all of the unit plates constituting the bottom had planes other than right-angled quadrilaterals, but in the tank of the present invention, A unit plate having a right-angled quadrilateral substrate may be used in a part of the bottom. Furthermore, in the unit plates used in FIGS. 1, 3, and 4, all planes other than the right quadrilateral were fan-shaped or fan-shaped; however, in this invention, various other A unit plate whose substrate is a plane other than a right quadrilateral is used. A plane other than a right-angled quadrilateral as used herein means a plane other than a square or a rectangle.

Examples of such planes include, in addition to the fan-shaped and fan-paper shapes described above, planes obtained by replacing the arcuate sides of the fan-shaped or fan-shaped shape with straight lines, curves other than circular arcs, bent lines, etc. Specifically, this includes, for example, an equilateral triangle, an isosceles triangle, an isosceles trapezoid, a pentagon in which all three adjacent interior angles are right angles, and a concave octagon in which two adjacent interior angles are dominant angles. It will be done. It also includes planes obtained by further dividing these, such as scalene right triangles, scalene trapezoids, etc. These require that at least one side is curved or that at least one interior angle is not a right angle. Further, it is desirable that at least one interior angle is a right angle or an acute angle. These unit plates can be made of metal or synthetic resin. According to this invention,
An example of a tank having a shape other than a cylinder is as follows.

In Figure 7, a tank with an oval bottom is assembled.
The oval-shaped bottom consists of a fan-shaped unit plate 1A and a rectangular unit plate 8.
It is composed of A. At the periphery of the bottom, there is a side wall unit plate 6.
B is erected. In FIG. 8, a tank with a square bottom and rounded corners is assembled.

The bottom of this tank is fan-shaped unit plate 1A1 rectangular unit plate 8
A and a square unit plate 8B. The side wall is composed of unit plates 6C. In FIG. 9, a tank with a semicircular arch-shaped bottom is assembled.

The semicircular arch-shaped bottom is composed of a fan-shaped unit plate 1A and a rectangular unit plate 8C. The side wall is composed of unit plates 6B and 6D. In FIG. 10, a tank with a regular octagonal bottom is assembled.

The bottom of the regular octagon is composed of a unit plate 9A1 having a pentagonal substrate whose three adjacent interior angles are right angles, and a unit plate 9B having a concave octagonal substrate whose two adjacent interior angles are dominant angles. has been done. A side wall unit plate 6E is provided upright on the periphery of the bottom. In FIG. 11, a tank with a cocoon-shaped bottom is assembled.

The bottom of this tank is composed of a unit plate 1B1 having a sector-shaped substrate with a dominant central angle and a square unit plate 8B. The side wall is composed of unit plates 6C. In the tank of this invention, the liquid passage is provided at the connecting edge of the unit plate constituting the bottom, so when draining water from the tank, even if the water level is lower than the upper end position of the connecting edge of the unit plate, Water moves from the top of one unit plate to the other unit plate through the liquid passage and is discharged through the drain hole.

Therefore, the tank of this invention has good drainage. Also,
Since the bottom of the tank of the present invention is assembled by internal assembly, assembly, inspection, and repair of the bottom are easy. Also,
Since the bottom is provided with a recessed part, there is an advantage that the dust that has entered the tank will not accumulate in the recessed part and will not be mixed into the water discharged from the tank.
