Description

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

It has already been practiced to assemble large containers such as tanks from a large number of right quadrilateral unit plates. As such a unit board, a board having a rectangular rectangular shape and having joining edges protruding to the same side on the four peripheries thereof is widely used. The joining edge referred to here is
Slanted bond edges that are inclined at an angle of 135 degrees relative to the substrate and upright bond edges that are upright relative to the substrate are known. In addition, as a unit board, there is one that has both inclined joint edges and upright joint edges on the four peripheries of the board,
A device having only one of them is used.
To enable inspection of the bottom from below, this tank is usually installed on parallel standing steel or concrete walls with a height of 45 cm or more.

A tank assembled from unit plates as described above has a drawback in that the side walls bulge outward when filled with liquid. As a means for eliminating this drawback, it is known to provide a stay within the tank that supports two side walls that are perpendicular to each other or that face each other. However, when such a stay is attached inside the tank, there is a drawback that it becomes an obstacle when cleaning the inside of the tank. Therefore, an attempt was made to reinforce the tank from the outside.

One such attempt is described in Japanese Patent Publication No. 54-27964. This publication proposes that a column made of shaped steel be erected on the outside of the side wall, the shaped steel be brought into contact with the outer surface of the side wall, and the lower end of the shaped steel be fixed to the ground hardened with concrete. However, when using this method, the supporting support was insufficient because the pillars were upright. Separately, as a reinforcing structure for assembled pools, supporting the side walls with diagonal stays installed on the outside was proposed in 1973.
This is proposed in Publication No. 19892. However, if the side wall of a tank installed on a shaped steel or vertical wall is supported from the outside with diagonal stays, the lower end of the stay will be far away from the side wall, resulting in the stay being too long. The drawback was that it took up too much space.

The inventor set out to remedy the above-mentioned drawbacks. Then, extend the section steel or vertical wall to the outside of the tank, or provide an independent concrete protrusion on the outside of the tank, and fix the lower end of the stay to the upper end of the extension or protrusion so that the stay is against the side wall of the tank. It was discovered that by making the stay extend obliquely within a substantially vertical plane, the length of the stay can be shortened and the space for installing the stay around the tank can be reduced. This invention was made based on such knowledge.

In other words, this invention is a tank in which the side walls and bottom of the tank are constructed by connecting right-angled unit plates in the same plane and in orthogonal directions, and the bottom is placed on a vertical wall made of section steel or concrete that is arranged in parallel. ,
Extending a section or standing wall to the outside of the bottom or by providing a concrete projection outside the bottom in a plane substantially perpendicular to the side wall through the extension or projection;
This is a reinforced assembled tank in which a stay is inserted diagonally between an extension part or projection and a side wall, the lower end of the stay is fixed to the upper end of the extension part or projection, and the upper end of the stay is fixed to the side wall.

The reinforced assembled tank according to this invention will be explained as follows based on the drawings. Figure 1 shows

FIG. 7 is a partially cutaway perspective view showing still another example of the reinforced assembled tank according to the invention.

In FIG. 1, the bottom and side walls of the tank are assembled from right-angled unit plates 1A. Unit plate/A is a right-angled rectangular (square in the figure) substrate 1
An inclined joining edge 12 that is inclined at an angle of approximately 135 degrees with respect to the substrate 11 is provided on the four circumferences of the substrate 1, and an upright joining edge 13 that stands upright with respect to the substrate 11 is provided beyond that. The bottom of the tank is placed on section steel 2 arranged in parallel. The section steel 2 extends outward from the bottom and includes a stay 3 between the extension 21 and the side wall in a plane passing through the extension 21 and substantially perpendicular to the side wall.

In the above tank, the substrate 11 of the unit plate 1A
may be rectangular. In addition, the substrate 11 has a rectangular, octagonal, circular, cross, and
It is possible to provide irregularities such as character shapes. Furthermore, the entire substrate 11 may have fine irregularities, and the entire substrate may be inclined, bulged, or depressed. This unit plate is made of reinforced synthetic resin (eg glass fiber reinforced polyester resin) or metal (eg iron). When the unit plates 1A are connected in the same plane, the upright joint edges 13 are in contact with each other, and when they are connected in orthogonal directions, the inclined joint edges 12 are in contact with each other, and there is no space between the contact surfaces. A gasket (not shown) is clamped and fixed with a bolt (not shown). It is desirable that the side wall unit plate 1A has the upright joint edges 13 facing outward.

As the section steel 2, H section steel or channel steel is used. A connecting member 22 that is orthogonal to the adjacent section steels 2 can be fixed between them. The connecting material 22 is made of an angle, channel steel, or H that is thinner than the shape steel 2.
Made of shaped steel, etc. When placing the bottom on the section steel 2, it is desirable to position the upright joint edge 13 of the bottom component plate 1A on the section steel 2 or the tie material 22. The length of the extension part 21 of the section steel 2 is the unit plate 1A.
The length of one side or the height of the side wall is preferably one-third or more and the height of the side wall is less than or equal to the height of the side wall.

As the stay 3, a round bar, square bar, pipe, steel band, angle, channel steel, etc. are used. Stay 3
The appropriate angle between this and the horizontal direction is about 30 to 75 degrees. When fixing the lower end of the stay 3, it is convenient to bend the lower end of the stay 3 parallel to the upper surface of the section steel 2, or to weld a small plate or collar to the lower end, and attach a stay lock to the lower end. is even more convenient. In this case, the stay lock 4 has an upright piece 42 on a small plate 41, the lower end of the stay 3 is fixed to the upright piece 42, and the small plate 41 is fixed to the upper surface of the section steel 2. Appropriate. Further, when fixing the upper end of the stay 3 to the side wall, the upper end may be directly fixed to the upright joining edge 13 of the side wall constituent unit plate 1A, but it can also be fixed using the above-mentioned stay lock 4. When using the stay lock 4, it is appropriate to fix one side of the angle piece 43 to the back side of the small plate 41 with bolts or welding, and fix the other side of the angle piece 43 along the upright joint edge 13. . In this case, it is desirable that the stay lock 4 be located on the intersection of the four unit plates 1A.

3 and is assembled from unit plates 1C having only upright joint edges 13 along the remaining three sides. As the substrate 11, a heat insulating material (for example, synthetic resin foam) is used.
15, a generally slanted example is shown. Similar to FIG. 2, the shaped steel 2 and the vertical wall 5 are extended to the outside of the bottom, and the stay 3 is interposed between the extended portion and the side wall. The stay 3 extends in a plane substantially perpendicular to the side wall. A pipe is used as the stay 3. A stay lock 4 is attached to both ends of the stay 3. A stay lock 4 at the lower end is fixed to the upper surface of the section steel 2. An angle piece 43 is fixed to the back side of the upper stay lock 4, and with this angle piece 43 in contact with the upright joint edge 13 extending laterally,
A platelet 41 is secured to an angle 14 along a vertically extending upright joint edge 13.

In FIG. 4, two stays 3 are provided at different angles, but both extend in a plane substantially perpendicular to the side wall. An angle is used as the stay 3. The lower ends of the two stays 3 are fixed to the same stay lock 4. Note that the tank is assembled from a unit board 1A having a substrate 11 with unevenness.

In FIG. 5, a concrete protrusion 6 is provided on the outside of the bottom. The base portion of the protrusion 6 is constructed integrally with the standing wall 5. The protrusion 6 may be columnar or continuous in a frame shape. It is desirable that the height of the protrusion 6 is approximately equal to the height of the vertical wall 5. Two stays 3 are interposed between the upper end of the projection 6 and the side wall, and both stays 3 extend in a plane substantially perpendicular to the side wall. As the stay 3, a steel band and a channel are used. The lower ends of the two stays 3 are fixed to the same stay lock 4. A plate 34 with a U-shaped cutout is fixed to the upper end of the stay 3, and the plate 34 with a U-shaped cutout is fixed to straddle the upright joint edges 13 of the two unit plates 1A. .
In this figure, a lid made from the unit plate 1B is attached to the upper end of the side wall.

In Fig. 6, the concrete standing wall 5 is extended to the outside of the bottom, and two stays 3 are inserted between the extension part 52 and the side wall. and extends in a plane substantially perpendicular to the plane. The lower ends of the stays 3 are each fixed to an upright piece 53 protruding from the upper surface of the extension part 52 of the upright wall 5. The lower part of the upright piece 53 is the extension part 5
It is welded to a reinforcing bar 54 buried within 2. The upper end of the stay 3 is fixed to the upright joining edge 13 using a plate 34 having a U-shaped notch.

In FIG. 7, similar to FIG. 3, the section steel 2 and the vertical wall 5 are extended to the outside of the bottom, and two stays 3 are inserted between each extension and the side wall of the tank. , both stays 3 extend in a plane substantially perpendicular to the side wall. The upper ends of the two stays 3 are fixed on the intersection of unit plates located at different heights. Inside the tank, a horizontal stay 7 is inserted between fixed portions of stays 3 located symmetrically across a ridgeline formed by intersecting adjacent side walls. Small plates 71 are welded to both ends of the horizontal stay 7, or
Alternatively, a stay lock 4 is attached, and a small plate 71 or a stay lock is fixed to a corner of the base plate 11 of the side wall unit plate 1B. This horizontal stay has the effect of preventing the side wall of the tank from twisting and tilting. The same effect can be obtained by using a right triangular plate instead of the horizontal stay 7 and fixing its two orthogonal sides to the substrate 11 of the orthogonal unit plate.

The reinforced tank according to this invention is a tank whose bottom is placed on parallel shaped steel or concrete standing walls, and the shaped steel or standing walls are extended to the outside of the bottom, or concrete protrusions are provided on the outside of the bottom. Therefore, a strong foundation suitable for fixing the stay was formed at a position higher than the ground outside the bottom. and in a plane passing through the extension or protrusion of the section or vertical wall and substantially perpendicular to the side wall;
Since the stay was fixed diagonally across between the extension or protrusion and the side wall, compared to the case where the stay was stretched between the ground and the side wall,
The length of the stay is short, the space around the tank for installing the stay is small, and the twisting of the side wall is reduced. Since the lower end of the stay is fixed on the extension or protrusion, it can be firmly fixed. This invention has excellent advantages as mentioned above.
