Description

[Detailed Description of the Invention] This invention relates to an assembly type container in which the joint is made airtight.

Assembling large containers such as tanks from a large number of unit plates is already practiced.

As such a unit plate, one in which an inclined joining edge is provided around the periphery of a right angled board and an upright joining edge is provided at the tip thereof (Japanese Utility Model Publication No. 42-3963) is actually used.

Further, as a unit plate used for attaching a partition wall to the above-mentioned container, at least one edge of the above-mentioned unit plate has an upright joining edge cut out, and a corner portion of the upright joining edge adjacent to this is cut out at a 45° angle. Notched at an angle (Jikko Sho 50-372
No. 12) has been proposed.

To connect the above unit plates to each other in a coplanar manner, the upright joint edges of adjacent unit plates are brought into contact with each other, and the packings are interposed and fixed with bolts.

In addition, in order to connect each other perpendicularly, the inclined joining edges of adjacent unit plates are brought into contact with each other and similarly fixed.

A container is constructed by repeating the above-mentioned connections. For example, in the transition from the bottom of the container to the side wall or partition wall, two unit plates are connected orthogonally to each other, and this orthogonal body is further connected to another unit. Similar orthogonal bodies are extended in the same plane, and there are many places where these four unit plates touch each other at one position.

At this contact point, since the four unit plates contact each other at only one point, leakage is likely to occur.

Conventionally, as a member to maintain this contact point airtight, a rod extending in the axial direction from the apex of the inner block made of a hard material such as plastic or metal and made of a square pyramid or a truncated square pyramid was provided at the central axis position. A corner block (Utility Model Publication No. 4822265) was used in which the rod was passed through an outer block made of a triangular prism made of a hard material.

In this corner block, the inner block is brought into contact with the contact points of the four unit plates as described above, and the rod is made to protrude outside the container.
It was used by inserting the outer block into the rod from the outside and securing it with a nut.

However, in this corner block, the square pyramid or truncated square pyramid is made of a hard material, so when it comes into contact with the contact points of the four unit plates, the ridgeline of the square pyramid or truncated square pyramid and the joint between the single plate There was a drawback that it was difficult for the two to come into close contact with each other.

Further, although the above-mentioned corner blocks can be used in the transition from the bottom of the container to the side wall, they have the disadvantage that they cannot be used in the transition from the bottom of the container to the partition wall.

This is because when trying to abut this corner block on the transition area from the bottom of the container to the partition wall, the upright joining edge of the adjacent bottom tank forming unit plate exists in the direction in which the rod protrudes. This is because the corner blocks cannot be brought into contact with each other.

This invention was made to improve the above-mentioned drawbacks.

That is, in this invention, an inclined joining edge is provided on the periphery of a right-angled board, and an upright joining edge is provided at the tip of the unit plate, and the inclined joining edges of the unit plates are brought into contact with each other, so that the unit boards can be connected to each other. are connected in a perpendicular state to form a rectangular body, the two orthogonal bodies are brought into contact with each other, the upright joining edges are connected to each other, the unit plates of each orthogonal body are extended in the same plane, and mutually orthogonal grooves are formed between them. A container in which a block is brought into contact with the intersection of the grooves, the block is a square pyramid or a truncated square pyramid, and at least the slopes thereof are made of a flexible material, and projections are provided along the four ridge lines formed by the intersection of the slopes. This is an assembly type container in which the above ridge line is located along the joint of the unit plates, the top of the block is covered with a plate, the plate is fixed on the unit plate, and a part of the plate is pressed against the block. .

The assembled container of this invention will be explained as follows based on the drawings.

FIG. 16 is a partially cutaway perspective view showing another example of the assembly type container of this invention.

In FIG. 1, the assembly type container of this invention has a unit plate IA
, IB and 1C.

The unit board 1A includes a substrate 1 on the four peripheries of a right-angled substrate 11.
an inclined joint edge 1 inclined at an angle of approximately 135° to 1;
2, and an upright joining edge 13 that stands upright at an angle of approximately 90° with respect to the substrate 11 is provided at the end of each inclined joining edge.

This unit plate 1A is used for the bottom, side wall, and part of the partition wall of the container.

In the partition wall, the unit plate 1A is used in a portion where the partition wall does not contact either the side wall or the bottom.

The unit plate 1B is obtained by removing one upright joint edge 13 from the unit plate 1A, and cutting out the corner portion of the adjacent upright joint edge 13 at an angle of approximately 45°.

This unit plate 1B is used in a portion where the partition wall is in contact with either the bottom or the side wall.

The unit board 1C has two adjacent units in the unit board 1A.
Two upright joining edges 13 are removed, and the corners of the upright joining edges 13 adjacent to these are cut out at an angle of approximately 45°.

This unit plate 1C is used in a portion where the partition wall contacts both the bottom and side walls.

These unit plates are adjacent to each other, and their slanted joints or upright joint edges are brought into contact with gaskets (not shown) in between, and are connected with bolts (not shown).

In this way, two unit plates are connected orthogonally at the transition from the partition wall to the bottom, from the partition wall to the side wall, or from the side wall to the bottom, and another similar unit board is connected to this orthogonal body. There are many locations where orthogonal bodies are joined in the same plane.

At this location, since the four unit plates are in contact at only one point, leakage is likely to occur.

In the container of this invention, block 2A is placed in such a place.
is in contact.

The block 2A is a truncated square pyramid made of a flexible material as shown in FIGS. 2 and 3.

A truncated pyramid has two surfaces 21 A and 21 B that are perpendicular to each other.
, a ridgeline 22A is formed as the intersection thereof, and two surfaces 21C and 21D that are orthogonal to each other are formed,
Another ridgeline 22B is formed as the intersection, the former ridgeline 22A and the latter ridgeline 22B are perpendicular to each other, and the four surfaces 21A to 21D form slopes.

Between the ridge lines 22A and 22B, ridge lines 22C and 22
D is formed.

23 is the bottom surface. A band-shaped projection 24 is integrally provided on each slope.

The protrusions 24 follow the ridgelines 22A to 22D and exist continuously around the central axis of the truncated quadrangular pyramid.

As shown in the figure, it is desirable that the protrusions 24 protrude in a pleat shape, and that the protrusion direction is directed toward the side where the apex 26 is present.

Note that the bottom surface 23 may be provided with a depression, and the ring-shaped protrusion 25 may be provided in the depression.

The ring-shaped projection surrounds the central axis of the truncated pyramid.

Natural rubber, neoprene, ethylene propylene rubber, silicone rubber, etc. are used as the flexible material for making this truncated pyramid.

When the block 2A is brought into contact, its four slopes are brought into contact with the inclined joint edges of the unit plates, as shown in FIG.
The ridge lines 22A and 22B are brought into contact with the ■-shaped grooves formed between the unit plates.

At this time, it is desirable to apply a joint material such as a ribbon sealer on the slopes 21A to 21D.

The top of block 2A is covered with plate 3A, 3B, 3C or 3D.

The plate 3A is bent at right angles in an angular shape, and bolts 4 are welded to each piece.

The protruding side of the fold is provided on the block 2A, a portion of the fold is directed toward the block 2A, and a portion of the fold is in contact with the exposed surface of the block 2A.

The bolt 4 passes through the unit plate, and by tightening a nut (not shown) from the back side, the plate 3A is pressed toward the unit plate.

As a result, a part of the fold of the plate 3A becomes part of the block 2A.
is being forced on.

Plate 3B is obtained by bending the plate 3A in a zigzag manner at three points along a line perpendicular to the fold, and protruding the portion sandwiched between the three folds into a square pyramid shape. .

The plate 3C is the same as the plate 3B except that the protruding portion is shaped like a truncated square pyramid.

The plate 3D has a hollow columnar body 3 on the fold in the plate 3A.
1.

In these plates, protrusions or columns abut against blocks.

It is desirable that a hard flat plate (made of corrosion-resistant material such as stainless steel or plastic) 5 be present between the columnar body 31 and the block 2A.

In FIG. 1, blocks 2B to 2J shown in FIGS. 4 to 12 can be used instead of block 2A.

The block 2B in FIG. 4 has ridge lines 22A and 22 along the edge of the bottom surface 23 in the block 2A in FIG.
A wing piece 27 is integrally provided at a position slightly apart from the edge of B.

The wing piece 27 can have any shape other than the illustrated trapezoid, such as a semicircle or a triangle.

The thickness of the wing piece 27 is preferably about 3 to 1Q mm, and the protrusion width is preferably 2 mm or more beyond the surface connecting the tips of the protrusions 24.

Note that it is desirable that the direction in which the wing pieces 27 protrude is approximately perpendicular to the central axis of the truncated square pyramid.

The wing pieces 27 serve to prevent the block 2B from co-rotating within the groove with the rotation of the bolt 4 when the block 2B is pressed into the intersection of the groove formed by the inclined joint edge 12.

A block 2C shown in FIG. 5 is the block 2B shown in FIG. 4 in which the wing pieces 27 are positioned in contact with the ends of the ridge lines 22A and 22B.

Block 2D shown in FIG. 6 differs from block 2B in FIG.
It exists isolated on D.

The block 2E shown in FIG. 7 is different from the block 2A shown in FIGS. 2 and 3 in that a hard flat plate 5 (
(see Figure 1).

A ring-shaped protrusion 51 may be provided on the exposed surface of the flat plate 5.

The block 2F shown in FIG. 8 is the same as the block 2E shown in FIG. 7, except that a square pyramid is used instead of the truncated square pyramid, and a flat plate 5 is embedded therein.

In that case, the flat plate 5 does not need to be made of a corrosion-resistant material.

Further, as shown in the figure, a hole may be formed in the flat plate 5, and a flexible material forming a quadrangular pyramid may enter the hole.

Note that the protrusion 24 has a trapezoidal cross section.

A block 2G shown in FIG. 9 uses a truncated square pyramid 6 made of a hard material in place of the flat plate 5 in the block 2E shown in FIG.

Note that the cross section of the protrusion 24 is semicircular.

The block 2H shown in FIG. 10 is the block 2G shown in FIG.
In this case, the main body is a square pyramid, and a double pyramid 7 is used instead of a truncated square pyramid 6.

Block 2■ shown in FIG. 11 is block 2F in FIG.
In this case, a square pyramid 8 is used instead of the flat plate 5.

Note that if the tips of the protrusions 24 on the side closer to the bottom surface 23 are directed toward the bottom surface, water can be prevented from entering along the slope.

A block 2J shown in FIG. 12 is the same as the block 2A shown in FIGS. 2 and 3 in which a through hole 28 is provided at the central axis position.

This hole 28 connects block 2J to Utility Model 48-22265.
Like the corner block in the publication, it is used to insert bolts when tightening bolts and nuts.

Further, in place of the plates 3A to 3D in FIG. 1, plates 3E to 3G shown in FIGS. 13 to 15 can be used.

The plate 3E shown in FIG. 13 has a columnar plate 31 in the plate 3D.
A square pyramid 32 is provided instead.

The plate 3F shown in FIG. 14 has a columnar body 31 in the plate 3D.
A truncated square pyramid 33 is provided instead.

A plate 3G shown in FIG. 15 is the same as the plate 3A except that bolt insertion holes 34 are provided in place of the bolts 4.

Furthermore, as shown in FIG. 16, a plate 3H in which a diagonal piece 35 is provided between two angular orthogonal pieces and a hollow columnar body 31 is integrally provided on the back side of the diagonal piece 35 can also be used.

When fixing the above plate to the unit plate, it is desirable to insert a gasket between the plate and the unit plate.

As mentioned above, in the assembly type container of this invention, two unit plates are connected orthogonally to each other to form a rectangular body, and the orthogonal body is
The unit plates of each orthogonal body are brought into contact with each other, the unit plates of each orthogonal body are extended in the same plane, grooves are formed between them that are perpendicular to each other, and blocks are brought into contact with the intersection points of the grooves, and at least the slopes of the blocks are made of flexible material. Since we used a square pyramid or truncated square pyramid made of , the structure allows the slope of the block to be in close contact with the groove surface.

In addition, the block has a protrusion that spans the ridgeline, so
The joint material is blocked by the protrusions, and the block and groove surface are brought into closer contact.

Moreover, since the protrusions are crushed by the pressure of the block, even if the container wall bends slightly outward when the container is filled with liquid, the crushed protrusions will recover.
This prevents gaps from forming.

Therefore, the assembly type container of this invention is extremely unlikely to leak.

In addition, when pressing the block, the top of the block is covered with a plate and a part of the plate is pressed against the block without passing the rod through the block, so the installation work is easy. It can be used for both the part transitioning to the side wall and the part transitioning from the bottom to the partition wall.

The assembled container of this invention has the above-mentioned advantages.
