Description

[Detailed description of the invention] This invention relates to a gasket that is inserted between the unit plates to maintain airtightness between the unit plates when a container is assembled by connecting a large number of right-angled unit plates to each other. It is.

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

Such unit boards include one in which upright joint edges are provided on the four peripheries of a right-angled rectangular board (Utility Model Publication No. 40-27399), and one in which inclined joint edges and upright joint edges are provided on the four peripheries of a right-angled board. (Utility Model Publication No. 42-3963), and one in which either an inclined joining edge or an upright joining edge is provided around the four peripheries of a rectangular substrate (Utility Model Publication No. 51-140809) are used.

There are various ways of connecting the unit plates to each other when assembling the container, but one basic way of connecting them is to connect four unit plates in the same plane.

In such a case, in order to connect the four unit plates airtightly, a cross-shaped packing (Utility Model Publication No. 1987-4429) or a T-shaped packing (Utility Model Publication No. 48104725) should be applied to the corner of the unit plate. It has already been proposed that contact be made.

These packings are made up of tape-like pieces in which a base piece of a cross or a single character is doubled, and a core material is inserted at the intersection of the cross or a single character.

Japanese Utility Model Application No. 52-6962 also shows a special example of such a T-shaped packing.

The above-mentioned cross-shaped packing or T-shaped packing is convenient for keeping the corner portions of unit plates airtight.

However, since such a gasket only makes the corner of the unit plate airtight, in order to make the entire joint edge of the unit plate airtight, in addition to such a cross-shaped or T-shaped gasket, it is necessary to use an additional unit plate. It was necessary to use a long tape-like packing extending along the joint edge of the joint.

That is, the tape-shaped packing is cut in advance to a length slightly shorter than one side of the unit plate, and the cut tape-shaped packing is sandwiched between the joints of each unit plate, and both ends are cut into a cross-shaped packing or T-shaped packing. It was necessary to insert the tape-like pieces between two single-ply tape-like pieces in the packing to make it airtight.

This operation has become extremely complicated, especially when assembling large containers, because the number of unit plates to be connected increases.

Therefore, there was a desire for a padskin that could be inserted more easily.

This invention was made in response to such wishes.

That is, this invention forms lobes that divide the thickness of the tape-like piece into two near both ends of a long tape-like piece made of a flexible material, opens a gap between the two lobes, and inserts a core between the bases of the lobes. This is a gasket for container assembly made by inserting materials.

The packing for assembling containers of this invention will be explained as follows based on the drawings.

1 to 3 are perspective views showing an example of the container assembly packing of this invention.

FIGS. 4 to 9 are perspective views each showing an example of the core material used in this invention.

FIG. 10 is a partially cutaway exploded perspective view showing the container assembly packing of this invention in use.

In FIG. 1, split pieces 11 are formed at both ends of a long tape-like piece 1 made of a flexible material, dividing the thickness of the tape-like piece 1 into two.

The space between the two lobes 11 is opened, and the core material 2A is inserted between the bases of the lobes 11.

What is thus formed is the container assembly packing A of this invention.

As the flexible material constituting the tape-shaped piece 1, natural rubber, synthetic rubber, soft vinyl chloride resin foam, and neoprene rubber foam are suitable.

The length of the tape-like piece 1 is preferably such that the length of the splinter 11 is approximately 3 to 30 cm, and the length of the portion other than the splinter is approximately equal to the length of one side of the unit plate for container assembly. desirable.

The above lengths of one side are 50cm, 100cm, 15
Includes 0 cm, 200 cm or 250 cm.

The width of the tape-like piece 1 is about 2 to 7 cm, and the thickness is 0.2 cm.
It is preferably about 2 cm to 2 cm.

Note that, as shown in the figure, it is desirable to bend the two bag pieces 11 at right angles to opposite sides.

Suitable materials for forming the core material 2A include hard neoprene rubber, ethylene propylene rubber, silicone rubber, and closed-cell synthetic resin foam.

The core material 2A may have flexibility, but it is desirable that it has more rigidity than the tape-like piece 1.

In the illustrated example, the shape of the core material is a triangular prism, but the shape is not limited to this.

Is the length of the core material 2A approximately equal to the width of the tape-shaped piece 1?
Or preferably slightly shorter than this.

It is desirable that the core material 2A is adhered, adhered or welded between the bases of the lobed pieces 11 with its axis orthogonal to the longitudinal direction of the tape-like piece 1.

What is shown in FIG. 1 is the basic form of the packaging for container assembly according to this invention.

This idea also includes some modifications.

For example, the packing B for container assembly of this invention shown in FIG.
Here, the tape-like piece 1 is made by pasting together two thin tape-like pieces.

In the packing C for container assembly of this invention shown in FIG. 3, the axis of the core material 2A on one end side of the tape-like piece 1 is inclined at an angle of approximately 45° with respect to the longitudinal direction of the tape-like piece 1. .

In this case, as the tape-like piece 1, it is appropriate to cut out a thin piece bent in a dogleg shape at an angle of 135° from a flat plate and paste the pieces together.

This container assembly packing C is used when two unit plates are extended in the same plane and another extension is connected orthogonally to such an extension.

Furthermore, as another modification, a case in which core materials 2B to 2G shown in FIG. 4 to FIG. It will be done.

The core material 2B shown in FIG. 4 has a ring-shaped protrusion 21 integrally provided on the side surface of the core material 2A shown in FIG.

Instead of providing the protrusion 21 integrally, an O-ring may be fitted.

The core material 2C shown in FIG. 5 is different from the core material 2A shown in FIG.
The size of the cross section changes continuously from one end to the other.

The core material 2D shown in FIG. 6 is made by integrating two plates 22 and 23 that intersect in a T-shape.

As shown in the figure, it is desirable that the two plates 22, 23 have a tapered shape in which the thickness decreases toward the tip.

Further, it is desirable that the surface of the T from the head to the foot be a curved surface.

The length from the intersection of the head and foot of T to each tip is 2 to 3
．． Approximately 5 cm is appropriate.

The core material 2E shown in FIG. 7 is different from the core material 2D shown in FIG.
The thickness of the two plates 22 and 23 in the vicinity of their intersection is gradually reduced from one end of the intersection to the other end.

As a result, in the vicinity of the intersection, a right triangle 24 that can be inscribed within the wall thickness at one end is larger than a similar right triangle 25 at the other end.

One side of the right triangle 25 is desirably 2 to 1/5 of one side of the right triangle 24, and suitably about 1 to 5 mm.

The core material 2F shown in FIG. 8 is different from the core material 2D shown in FIG.
The thickness of the two plates 22 and 23 is constant except where they intersect, and two linear protrusions 26 are provided on the surface facing the outside of the head of the T and the curved surface facing from the head to the foot. It was established.

The number of linear protrusions 26 may be one or three or more.

Further, the length of the linear protrusion 26 may be from one end to the other of the head and feet of T, or may be only in the portion excluding the vicinity of the end.

The linear protrusion 26 may have a semicircular or triangular cross section.

The core material 2G shown in FIG. 9 is different from the core material 2E shown in FIG.
The width of the plates 22 and 23 is made smaller as they approach the tips, and two linear protrusions 26 are provided on the bent surface of the T from the head to the foot.

The height and width of this linear protrusion increase as it approaches the bent portion.

When using the core materials 2D to 2G, the plates 22 corresponding to the legs of the T are sandwiched between the lobes 11 of the tape-like piece 1 and bonded.

Note that the protrusions 21 and 26 are useful for improving airtightness at the intersections of the unit plates.

The container assembly packing of this invention is used as follows.

In FIG. 10, the side wall, bottom wall or top wall of the container is assembled from unit plates 3.

The unit board 3 includes a substrate 31 on the four peripheries of a right-angled rectangular substrate 31.
An inclined joining edge 32 is provided which is inclined at an angle of 135° with respect to the slanted joining edge 32, and an upright joining edge 33 is provided beyond that.

Two unit plates 3P and 3Q are arranged on the same plane, and the container assembly packing D of this invention is inserted between them.

The packing D is the packing B in Fig. 2, and the core material 2A.
The core material 2D shown in FIG. 6 was used instead of the core material 2D shown in FIG.

The lobes 11 of the packing D are brought into contact with the upright joining edges 33 of the two unit plates 3P and 3Q arranged in the same plane, and the tape-like pieces 1 other than the lobes are placed opposite each other on the two unit plates 3P and 3Q. It is sandwiched between upright joining edges 33.

Separately, two unit plates 3R and 3S are arranged on the same plane, and the container assembly packing D of this invention is inserted between them in the same way as before.

A long tape-shaped packing 4 is inserted between the two sets of unit plates.

This tape-shaped packing 4 is made of the same material as the tape-shaped piece 1, and is continuous over several unit plates or from end to end of the side wall, bottom wall, or top wall.

In this state, the opposing upright joining edges 33 are tightened with bolts (not shown).

The same applies to the case where a unit plate without an inclined joint edge is used instead of the unit plate 3.

The main body of the packaging for container assembly of this invention was made from a long tape-like piece, so when it was sandwiched between two unit plates arranged in the same plane, it was separately cut into pieces slightly shorter than one side of the unit plates. There is no need to use tape-like packing.

Therefore, it is difficult to cut the tape-like packing or to tie the two ends together.
The effort of inserting between stacked tape-like pieces is saved.

In addition, we formed lobes that bisect the wall thickness of the tape-like piece near both ends, and created an opening between the two lobes, so that the lobes could be connected to the upright joining edge of two unit plates connected in the same plane. The four unit plates can be airtightly connected by simply sandwiching a long tape-like packing between the two sets of connecting edges.

Therefore, here as well, the trouble of cutting the tape-like packing and inserting it between the tape-like pieces whose ends are doubled is saved.

Therefore, the use of the packing for assembling containers of this invention has the advantage that the work is extremely simple compared to the conventional packing.
