Description

[Detailed explanation of the invention] This invention is designed to ensure that when assembling a heat-retaining container, the bottom wall, side wall,
Used to join side walls or a side wall and a ceiling wall,
This invention relates to a joining member.

BACKGROUND ART Containers such as tanks have already been assembled in series from a large number of shallow box-shaped unit plates each having a joining edge provided on the periphery of a right-angled rectangular substrate.

This unit plate is made of iron or synthetic resin.

However, since such materials easily conduct heat, containers assembled from these unit plates have the disadvantage that it is difficult to maintain a constant internal temperature.

Therefore, when assembling a heat-retaining container, it has been proposed to use a sandwich structure in which a heat insulating material is included in the substrate (Japanese Utility Model Publication No. 51-72213 and Japanese Utility Model Application Publication No. 5174810).

It is true that when a container wall is assembled using the above unit plates, the thermal conductivity of the container wall itself becomes small.

However, since angles are used to join the container walls orthogonally at the ridgeline of the container, this portion does not contain any heat insulating material (see Article 5 of each of the above-mentioned publications).
(see figure).

As a result, it was not possible to reduce the heat conduction along the edges of the container.

The inventor attempted to remedy the above-mentioned drawbacks.

In order to reduce heat conduction from the ridgeline, we considered using a joining member containing a heat insulating material at the ridgeline.

As the joining member, it was considered to use a long bent body having an angular cross-section, with a layer made of a heat insulating material in contact with the inner side along the fold.

However, when a layer of heat insulating material is brought into contact with the folded body, the presence of the layer may interfere with tightening with bolts.

Therefore, we tried to make the layer exist along the entire length of the fold, but in the direction perpendicular to the fold, only halfway through the new curved body, leaving the rest as the joint edge.

As a result, it has been found that by doing so, the bolt can be passed through the joining edge, thereby avoiding the above-mentioned hindrance.

Moreover, it was found that even in this case, a sufficient heat insulating effect by the layer could be obtained.

Furthermore, they discovered that if a plate made of a hard material is placed against the exposed surface of the layer to envelop the layer, the layer is protected and lasts longer.

This invention was made based on such knowledge.

In other words, this invention is based on a long folded body made of a hard material with a cross-sectional shape, in which a layer of heat insulating material is brought into contact with the inside of the folded body along the fold, and the layer extends over the entire length of the fold. However, in the direction perpendicular to the fold, the folded body is only left halfway, and the rest is used as the joining edge, and a plate made of a hard material is brought into contact with the exposed surface of the layer to enclose the layer. It is a member.

The container wall joining member according to this invention will be explained as follows based on the drawings.

1 to 5 are partially cutaway perspective views showing an example of the container wall joining member according to the invention.

FIGS. 6 and 7 are partially cutaway perspective views showing how the container wall joining member according to the invention is used.

In FIG. 1, a layer 12 made of a heat insulating material is placed on the inside of a long bent body 11 made of a hard material and having a cross-sectional shape.
It is being touched.

The layer 12 exists over the entire length of the fold, but in the direction perpendicular to the fold, it is present only halfway through the new curved body, and the rest is the joining edge 18.

A plate 13 made of a hard material is brought into contact with the exposed surface of the layer 12, and the plate 13 wraps around the layer 12.

This structure is the container wall joining member 1A according to the present invention.

As the hard material for making the new curved body 11, metal such as iron or hard synthetic resin (for example, glass fiber reinforced polyester resin) is used.

It is desirable to fix flat plates 14 that stand upright from the inner surface of the folded body 11 to both ends of the folded body 11 in the longitudinal direction.

It is desirable that the flat plate 14 be formed integrally with the folded body 11 using the same material as the folded body 11 .

It is convenient to make Pol I insertion holes 15 in the joining edge 18 and the flat plate 14, avoiding the positions where the layers 12 come into contact.

As the layer 12 made of the heat insulating material, wood or the like can be used, but synthetic resin foam (eg, urethane foam, acrylic foam, etc.) is most preferable.

It is desirable that the layer 12 is continuous from end to end in the longitudinal direction of the folded body 11 along the fold.

The cross-sectional shape of the layer 12 can be any shape other than the illustrated right-angled rectangle.

As the hard material for making the plate 13, the same material as described for the folded body 11 is used.

The plate 13 and the new curved body 11 may be made from the same material or from different materials.

For example, the bent body can be made of metal and the plate 13 can be made of synthetic resin.

What is shown in FIG. 1 is a typical example of the container wall joining member according to this invention.

This invention includes various other embodiments.

For example, a container wall joining member 1B of this invention shown in FIG.
In this case, the ridgeline of the folded body 11 is continuously chamfered from end to end to form a surface 16.

In the container wall joining member 1C of this invention shown in FIG. 3, the surface 16 in FIG. 2 ends slightly before one end, and a ridge line 17 is left at the end.

In the container wall joining member 1D of this invention shown in FIG. 4, the cross section of the layer 12 made of the heat insulating material and the flat plate 14 are fan-shaped.

In the container wall joining member 1E of this invention shown in FIG. 5, the tip of one of the bent pieces of the bent body 11 is bent at a right angle, and as a result, the bent body 11 has a U-shaped cross section. ing.

The length of the container wall joining member according to this invention is arbitrary; for example, it may be equal to the length of the ridgeline of the container, but it may be a constant length smaller than the length of the ridgeline. desirable.

The fixed length includes not only the basic length but also half the basic length or an integral multiple of the basic length.

For example, a suitable basic length is 1 m.

Furthermore, when assembling a container wall from a large number of unit plates, it is desirable to determine the basic length based on the length of one side of the unit plates.

The container wall joining member of this invention is used, for example, as follows.

In FIG. 6, the container wall is assembled from a number of unit plates 2.

The unit board 2 includes a substrate 21 on the four peripheries of a right-angled rectangular substrate 21.
A shallow box-shaped body is formed by providing an upright joint edge 22 that stands upright against the base.

On this unit board 2, a layer 23 made of a heat insulating material is brought into contact with the entire surface of the board from the inside of the box, and the peripheral edge of the layer 23 is connected to the upright joint edge 22.
It extends to the inner surface of the tube and is located away from its tip.

The exposed surface of layer 23 is covered with a plate 24.

The upright joining edges 22 of the plurality of unit plates 2 are brought into contact with each other, and are deflected with bolts 3 with a gasket (not shown) in between,
The upright joint edges 22 are directed outwardly and define the container wall.

A container is constructed by combining a plurality of such container walls.

Along the ridgeline of the container, at a portion where two container walls are perpendicular to each other, the container walls are joined via the container wall joining member 1A according to this invention.

The joining edge 18 of the member 1A is brought into contact with the distal ends of the upright engaging edges 22 of two unit plates 2 that are orthogonal to each other, and is fixed with a bolt 3 with a packing (not shown) sandwiched therebetween.

As the member 1A, one having a length equal to one side of the unit plate 2 is used, and a plurality of members 1A are connected so as to extend along the longitudinal direction.

At the connecting portion, the flat plates 14 of the two members 1A are brought into contact and connected.

The contact surface is located on an extension of the joint of the unit plate 2.

At the vertex formed by the intersection of the containers, three mutually orthogonal members 1A are joined using the joining block 4.

The block 4 has three flat plates 41 connected to each other so as to be perpendicular to each other, a layer 42 made of a heat insulating material is brought into contact with the intersection point from the inside, and the exposed surface of the layer 42 is covered with a plate 43.

The flat plate 41 is in contact with the flat plate 14 of the member 1A and is fixed with bolts.

In the container shown in FIG. 7, container wall joining members 1B and 1C of this invention are used in place of the member 1A in FIG. 6.

At the vertex formed by the intersection of the container ridgelines, two members 1B
and one member 1C are brought into contact with each other at one end.

In the member 1C, the side on which the ridge line 17 remains is directed toward the apex.

In parts other than the apex, the member 1B is the member 1 in FIG.
It is used in the same way as A.

When joining the unit plates 2 via the members 1B and 1C, it is desirable to expose the surfaces 16 of the members 1B and 1C to the inside of the container.

Since the container wall joining member of this invention includes a long bent body made of a hard material and having a cross-sectional shape, it can be used to connect container walls assembled from unit plates as an alternative to conventional angles. .

In addition, since a layer of heat insulating material was placed in contact with the inner surface along the fold of the new curved body, and the layer existed along the entire length of the fold, when this member was used to join the container wall at the ridgeline of the heat-retaining container, the container Heat conduction from the ridgeline becomes extremely small.

In addition, since the layer of heat insulating material is only present up to the middle of the folded body in the direction perpendicular to the fold, and the rest is used as the joint edge, this joint edge can be overlapped with the joint edge of the unit plate and fixed with bolts. , those that do not include a heat insulating layer are fixed together,
Pol I. is well tightened, and the tightened part does not cave in or break.

Furthermore, since a plate made of a hard material is placed in contact with the exposed surface of the layer of heat insulating material to enclose the layer, rainwater is prevented from hitting or seeping into the layer, and the layer lasts for a long time.

This invention has excellent effects as described above.
