Description

[Detailed Description of the Invention] This invention relates to a tank having at least two walls that intersect with each other, and in which the two walls are supported by struts so that the two walls do not bend relative to each other.

The larger the capacity of a liquid storage device such as a tank, the more likely its side wall will bend outward when it is filled with liquid.

Therefore, large-capacity tanks must be reinforced to prevent the side walls from bending.

One of the methods commonly used in the past to meet this need is to insert a metal rod between the opposing side walls and fix both ends to the side walls to maintain a constant distance between the side walls. It is.

However, in large-capacity tanks, the distance between opposing side walls is large, so when a metal rod is passed between the opposing side walls, the metal rod itself bends significantly.

Therefore, as an alternative method, a shaped steel such as an angle or channel is inserted diagonally between two walls that intersect with each other, a flat plate parallel to the wall is attached to both ends of the shaped steel, and the flat plate is brought into contact with the wall and bolted. It was proposed to fix the
No. 412).

Although this method was able to achieve the purpose of reinforcement, it was economically unfavorable because shaped steel is more expensive than metal rods.

The inventor considered that a metal rod could not be used in place of the section steel in the above method.

Then, insert a metal rod diagonally between two orthogonal walls, bend each end perpendicular to the wall, make the bent end penetrate the wall and protrude from the back side of the wall, and make the protruding part look like a nut. I thought about fixing it with something.

However, when both ends of a metal rod are bent, there is a slight roundness at the bent part, so when using this method, a metal rod that is diagonally crossed between two orthogonal walls will be slightly rounded very close to the wall surface. It was decided to bend with a roundness.

As a result, the rounded part acted as a spring, allowing the side wall to flex.

Therefore, in order to eliminate the above-mentioned drawbacks, this inventor covered the folded part with the thick wall of the flange, fixed the flange and the metal rod, and brought the flange surface into close contact with the inner surface of the wall. The idea was to prevent the roundness of the part from acting as a spring.

This idea was made based on this idea.

In other words, this idea has two parts that intersect with each other at the corners of the tank.
Pass a metal rod between the walls, bend the end of the metal rod perpendicular to the wall inside the tank, provide a tsuba at the bent part, make the side of the tsuba that faces parallel to the tank wall, and This is an internally reinforced tank made by fixing a metal rod to the wall by protruding the end of the rod from the wall, attaching a fixture to the protruding part, and pulling the collar toward the wall with the fixture.

The internally reinforced tank according to this invention will be explained as follows based on the drawings.

FIG. 8 is a partially cutaway perspective view showing still another example of the internally reinforced tank of this invention.

In Figure 1, two walls a intersect with each other at the corner of the tank,
l) A metal rod 1 is inserted between them.

Both ends of the metal rod 1 are bent perpendicularly to walls a and b within the tank.

A flange 2 is attached to the bent portion, and as shown in FIG. 2, the entire rounded portion of the bent portion 11 is covered with the flange 2.

As shown in FIG. 1, the ends of the metal rod 1 protrude from walls a and b, and a fixing device (nut 14 in the illustrated example) is attached to the protruding portion (threaded portion 12 in the illustrated example).

The collar 2 is pulled towards the wall a, t) by means of a fixture.

This structure is the internally reinforced tank according to this invention.

It is desirable that the walls a and l) are perpendicular to each other, but they do not necessarily have to be perpendicular to each other.

The walls a, l) may be one a bottom and the other a side wall, or both may be side walls, or one may be a partition wall and the other a bottom or a side wall.

As the metal rod 1, an iron or stainless steel rod is generally used.

The cross section of the metal rod may be either round or square (for example, hexagonal).

The thickness of the metal rod 1 varies depending on the size of the tank or the length between the flanges, but is generally about 12 mm.

The bending angles at both ends of the metal rod 1 may be the same or different.

When fitting the nut 14 into the threaded portion 12 of the metal rod 1, it is desirable to have a somewhat large washer 13 or plate between the nut 14 and the wall.

The collar 2 may be circular or polygonal.

In the case of a circular shape, it is desirable that the diameter is about 50 mm.

Moreover, it is desirable that the tsuba 2 be made of iron.

Welding is suitable for fixing the collar 2 to the metal rod 1.

In the case of welding, when the bent portion of the metal rod is covered with a tsuba, the tsuba includes the metal layer used for welding.

It is preferable to sandwich a packing 3 or a caulking material between the collar 2 and the wall a or b.

Note that the two walls a, t) of the tank may be a single plate or may be assembled from unit plates.

In the example shown in FIG. 1, both walls a and b are assembled from unit plates 4A.

The unit plate 4A has upright joining edges 42 provided around the four peripheries of a right-angled rectangular substrate 41.

This unit plate can be made of metal (e.g. iron) or reinforced synthetic resin (
For example, it is suitable to make it from glass fiber reinforced polyester resin).

Further, it is possible to provide irregularities in the portion of the substrate 41 other than the portion where the collar 2 contacts.

FIG. 1 shows one of the basic embodiments of the internally reinforced tank according to the invention.

This invention also includes the following embodiments.

In the tank shown in FIG. 3, two intersecting walls C1d are assembled from unit plates 4B.

The unit plate 4B has an inclined joining edge 43 provided around the four peripheries of a right-angled substrate 41, and an upright joining edge 42 provided beyond the inclined joining edge 43.

A metal rod 1 is inserted between the two walls c and d, as in the case of FIG. 1.

On the wall C corresponding to the side wall of the tank, the tip of the three-metal rod 1 penetrates the wall C and protrudes to the back side as in the case of FIG. It is fitted.

The tip of the threaded portion 12 further passes through the plate 5 and is fixed with a nut 15.

The plate 5 is abutted so as to straddle the upright joining edge 42 located near the penetration part of the metal rod 1, and is fixed to the wall C by bolts 6 at a position symmetrical to the threaded part 12.

Fit washers 61 into the bolts 6 on both sides of the wall C, and
It is desirable to sandwich the packing 3 between the wall C and the wall C.

The plate 5 described above serves to prevent the portion of the substrate 41 through which the metal rod 1 passes from being destroyed when a large tension is applied to the metal rod 1.

At the wall d, which is the bottom of the tank, the tip of the metal rod 1 protrudes from the wall d in the same way as above, and the bent plate 7 and the nut 1 are attached to the threaded part 12.
4 is set.

As shown in FIG. 4, the bending plate 7

It is fixed with a nut 14.

In the tank shown in Figure 6, ``is'' a tank similar to that shown in Figure 1.
Two metal rods 1 are stretched between walls (only one wall g is shown).

The lower ends of the two metal rods 1 are located near the contact points of the four unit plates 4A, symmetrically across the joints of the unit plates 4A, and as in the case of FIG. It is fixed using

In the example described above, the flanges 2 attached to the metal rod 1 were all plate-shaped, but the flanges 2 are not limited to plates.

For example, as shown in FIG. 7, it may be conical.

In the tank shown in FIG. 8, two metal rods 1 are strung between two walls, f, of a tank that is almost the same as that in FIG.

Both ends of the two metal rods 1 are located symmetrically on both sides of the joint of the unit plate 4A.

The lower end of the metal rod 1 is fixed using a bent plate 7B, almost the same as in the case of FIG. 6, and the upper end is fixed using a plate 5, almost the same as in the case of FIG. .

Note that a metal rod 9 extending horizontally is fixed to the top of the tank.

The internally reinforced tank of this invention uses metal rods as supporting members for two mutually orthogonal walls, resulting in low material costs.

In addition, the end of the metal rod is bent perpendicularly to the wall inside the tank, a flange is attached to the bent part, the end of the metal rod is made to protrude from the wall, a fixture is attached to the protruding part, and the flange is secured with the fixture. The metal rod is fixed to the wall by pulling it towards the wall, so
Easy to fix.

Furthermore, a flange is provided on the bent part of the metal rod, and the side of the flange facing toward the rod end is parallel to the tank wall surface, so the flange comes into close contact with the wall surface and prevents the bent part from acting as a spring. Therefore, the metal rod can be firmly fixed to the wall surface.

Therefore, according to this invention, the two walls that intersect with each other are firmly supported, and the two walls are completely prevented from being bent.

This invention has excellent advantages as described above.
