Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating unit plate for container assembly, and more particularly to a heat insulating unit plate for tank assembly suitable for containing and storing cooled or heated liquid. It is about boards.

[0002]

BACKGROUND OF THE INVENTION Tanks are required to store liquids. In order to install a tank for storing water, a prefabricated type was often used. Assembled type is made by carrying unit materials to the site and assembling the unit materials on site. Needless to say, the unit material in this case is made of a hard material,
The shape was often a shallow box shape with flanges standing upright on the four sides of a rectangular board. A metal or a hard synthetic resin was often used as the hard material. Such unit materials were called unit panels or simply panels.

When the liquid was cooled or warmed water, it was necessary to make the tank itself insulating. In order to make the tank itself heat insulating, it is convenient to make the panel itself heat insulating. Therefore,
Panels were built that incorporated thermal insulation. This is called a heat insulation panel.

As the heat insulating panel, one having a heat insulating material in contact with the entire surface of the substrate inside the panel formed in the above-mentioned shallow box shape was used. 58-61790
The gazette describes that an exposed surface of a heat insulating material is covered with a cover plate, the cover plate is stopped by a bolt penetrating the panel and the heat insulating material, and a space between the cover plate and the flange is filled with a sealing material to form a heat insulating panel. is doing. However, if the cover plate is stopped with bolts that penetrate the panel and the heat insulating material, liquid may leak around the bolts, and it is necessary to pay attention to the corrosion of the bolts. It wasn't enough.

Japanese Utility Model Publication No. 60-30222 discloses that a heat insulating material is bonded to an inner line of a panel, and a surface plate is brought into contact with an exposed surface of the heat insulating material to form a heat insulating panel. According to this description, liquid does not leak around the bolt, and there is no problem of corrosion of the bolt. However, there are some drawbacks.
The disadvantage is that when a tank is assembled using this type of heat insulating panel and liquid is put into the tank, the panel substrate is bent by hydraulic pressure, the heat insulating plate is cracked or the panel and heat insulating material are peeled off. there were.

According to Japanese Utility Model Publication No. 62-9274, the panel and the exterior plate are made of the same material, and the panel and the exterior plate are integrated, and a heat insulating material is wrapped therein to form a heat insulating panel. It has been described. In this case, the exterior plate is firmly integrated with the panel and therefore is less likely to bend. Therefore, it is possible to prevent the exterior plate from peeling off from the panel and the heat insulating plate from cracking. However, in order to do this, the exterior plate must be integrated at a position on the panel that is inside the bolt hole rather than the bolt hole. Therefore, if the thickness of the heat insulating material is increased, the protruding length of the flange is increased. Getting bigger,
Therefore, the width and height of the tank assembled by using the panel becomes large, and in a tank installed in a limited space such as a building, inspection and walking around the tank are hindered. Therefore, it was necessary to improve this point.

[0007]

SUMMARY OF THE INVENTION The present invention is intended to provide a heat insulating unit plate which does not have the above-mentioned drawbacks. That is, the present invention provides a unit plate having sufficient strength and a heat insulating effect, and when the unit plate is assembled in a tank, there is no risk of liquid leakage even if a liquid is put in the tank, and the unit plate An object of the present invention is to provide a heat insulating unit plate in which there is no fear that the plate is bent and the outer plate is peeled off or the heat insulating plate is broken, and the tank does not occupy a large volume.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An example of the heat insulating unit plate for container assembly according to the present invention will be described with reference to the drawings as follows. FIG. 1 is a partially cutaway perspective view of a known heat insulating panel used by the present invention. 2 and 3 are partially cutaway perspective views of the heat insulating unit plate according to the present invention. Figure 4
FIG. 4 is a partially cutaway enlarged sectional view of the unit plate shown in FIG. 3. Figure 5
6 and 6 are partially cutaway perspective views of the heat insulating unit plate according to the present invention. FIG. 7 is a partially cutaway enlarged view of the heat insulating unit plate according to the present invention. FIG. 8 is a partially cutaway perspective view of a container assembled using the heat insulating unit plate according to the present invention. FIG. 9 is a partially cutaway side view of a container assembled using the heat insulating unit plate according to the present invention.

Referring to FIG. 1, a known heat insulation panel used in the present invention is a rectangular quadrangular base plate 1 having flanges 2 on four sides.
The panel 3 is made by standing upright and forming a shallow box shape. The panel 3 is made by abutting the heat insulating material 4 on the entire surface of the substrate 1 inside the panel 3 and covering the exposed surface of the heat insulating material 4 with the exterior plate 5. The panel 3 and the exterior plate 5 are made of a hard material and are integrally connected to each other to enclose the heat insulating material 4. Bolt holes 6 are provided at some places of the flange 2 projecting from the exterior plate 5.

As the hard material forming the panel 3 and the exterior plate 5, plastic is often used, and among the plastics, polyester resin reinforced with glass fiber is often used. As the heat insulating material 4, foamed plastics, particularly urethane foams having closed cells, styrene resin foams, and ethylene resin foams are used.

The heat insulating unit plate according to the present invention uses the heat insulating panel as it is, as shown in FIG. That is, in the heat insulating unit plate according to the present invention, the heat insulating material 4 is attached to the panel 3.
A heat insulating panel that is wrapped with the exterior plate 5 is used, and a second heat insulating material 7 and a surface plate 8 are attached inside the heat insulating panel. More specifically, the second heat insulating material 7 is attached along the outer plate 5 of the heat insulating panel, and the exposed surface of the heat insulating material 7 is covered with the surface plate 8. Thus, the heat insulating unit plate of the present invention is manufactured. In that case, the surface plate 8 is bonded to the flange 2 while avoiding the vicinity of the bolt holes 6.

Here, the fact that the surface plate 8 is provided so as to avoid the vicinity of the bolt holes 6 means that the bolt holes 6 are connected when connecting the unit plates.
It means that the surface plate 8 is attached while leaving a space for passing a bolt through and tightening it with a nut. It goes without saying that the heat insulating material 7 must be provided in the vicinity of the bolt holes 6 before the surface plate 8 is formed in this manner.

The heat insulating material 7 may be of the same type as described for the heat insulating material 4. However, in one unit plate, what is used as the heat insulating material 7 is the heat insulating material 4
It may be different from that used for. Also, the surface plate 8
Needs to be made of a hard material, but the exterior plate 5
Unlike, it need not be integrally molded with the panel 3 and therefore need not be the same material as the panel 3 is made of.
However, they may be made of the same material.

Although the surface plate 8 is adhered to the flange 2 in FIG. 2, a joint material can be used for the adhesion. Since the joint material is putty-like and has an adhesive property, the front plate 8 can be bonded to the flange 2 by packing it between the front plate 8 and the flange 2. It goes without saying that an adhesive may be used instead of the joint material.

In FIG. 2, since the bolt hole 6 is located inward of the exterior plate 5, the surface plate 8 can be directly fixed to the flange 2. When the bolt hole 6 is close to the exterior plate 5 and the surface plate 8 is extended to the flange 2 so that the bolt cannot be inserted into the bolt hole 6, the surface plate 8 is fixed to the exterior plate 5. Will be required. Such a case is shown in FIG.

In FIG. 3, the surface plate 8 has a shallow dish shape,
The peripheral edge is adhered onto the exterior plate 5. The mode of adhesion is shown in enlarged form in FIG. In FIG. 4, the surface plate 8
When the plate is shaped like a dish, not only the peripheral edge of the surface plate 8 rises obliquely but also a step 9 is formed at the tip. The step portion 9 allows the surface plate 8 to prevent the use of the bolt hole 6 and allows the heat insulating material 7 to cover the surface of the exterior plate 5 as widely as possible. Further, the step portion 9 collects the adhesive 10 so that the adhesive can be surely adhered. This is preferable when the surface plate 8 is bonded to the exterior plate 5.

In FIG. 5, the surface plate 8 has a flange 2 along its entire circumference.
Away from the flange 2 only near the bolt holes 6
Has been shown to be preferred. More specifically, most of the peripheral edge of the surface plate 8 is in contact with the flange 2, and is separated from the flange 2 only near the bolt hole 6 to form a semi-conical space with the flange 2. ing. As a result, the surface plate 8 covers almost all the surfaces of the exterior plate 5, so that the heat insulating material 7 efficiently insulates the exterior plate 5. The surface plate 8 is preferably shaped like this.

FIG. 6 is similar to that shown in FIG. FIG. 6 shows that the panel 3 may be provided with the flange 2 that stands upright almost vertically from the substrate 1 as well as the flange 21 that stands up at an angle of approximately 135 degrees from the substrate 1. Further, it is said that the substrate 1 may not be a flat surface, but may project from a quadrangular pyramid having a flat center. In accordance with the protrusion of the substrate 1, the heat insulating material 4, the exterior plate 5, the heat insulating material 7, and the surface plate 8 are curved into a truncated pyramid shape. The heat insulating unit plate may be such.

Further, FIG. 6 shows that the surface plate 8 may be fixed to the exterior plate 5 by bolts 11. The bolt 11 has a plate 12 fixed to the head,
2 is adhered onto the exterior plate 5 so that the foot protrudes into the inner wall of the unit plate. Therefore, for example, when a styrene resin foam plate is used as the heat insulating material 7 and pressed against the exterior plate 5, the foam plate is in a state in which holes are made only at the bolts 11 and the legs of the bolts are penetrated. However, the foam plate may be pre-drilled at the bolt 11. The surface plate 8 has holes formed at the bolts 11, and when the holes are covered over the heat insulating material 11, the surface plate 8 is attached to the bolts 11.
The feet are projected. Therefore, the nut 13 can be fitted to the foot of the bolt 11 to fix the surface plate 8 on the exterior plate 5. At this time, the peripheral edge of the surface plate 8 is attached to the outer plate 5.
Alternatively, it may be adhered to the flanges 2 and 21.

The heat insulating unit plate having the structure shown in FIG. 6 has bolts 11 attached at the site when the unit plates are assembled at the site,
Then, the heat insulating material 7 and the surface plate 8 can be attached.
The structure shown in FIG. 6 is advantageous in that this structure can be used in the field.

FIG. 7 shows that when a heat insulating panel is made in a state in which the heat insulating material 4 is surrounded by the panel 3 and the exterior plate 5, the resin forming the panel 3 and the exterior plate 5 adheres well to the heat insulating material 4. Through the through holes 4 in places of the heat insulating material 4 so as to be integrated.
1 indicates that it is preferable to provide 1. That is,
When the through hole 41 is provided, the air accumulated in the mold at the time of molding escapes through the through hole 41 to the outside of the mold, so that the molding is facilitated and the resin flows into the through hole 41.
This is convenient because the resin adheres well to the heat insulating material and becomes an integral part.

Further, FIG. 7 shows that the heat insulating material 7 and the surface material 8 can be attached after the heat insulating panel is assembled into a container. Ie 2 insulation panels
One by one, the flanges 2 are made to face each other, and the bolts 14 are connected through the bolt holes. At this time, the bolt 16 welded to the plate 15 is brought into contact with the flange 2 to fix the plate 15 with the bolt 14, and the foot of the bolt 16 is fixed to the flange 2.
Let it stick out from. After that, the heat insulating material 7 is attached inside the heat insulating panel, the exposed surface thereof is covered with the surface plate 8, the feet of the bolt 16 are projected from the surface plate 8, and the nuts are attached to the feet of the bolt 16.
Can be fitted to fix the surface plate 8 to the flange 2. At this time, the heat insulating material 7 must be cut out near the bolts 14 and 16. When a resin foam plate is used as the heat insulating material 7, the foam plate can be attached as a plurality of layers.

FIG. 8 shows a container assembled using the heat insulating unit plate according to the present invention. In the figure, the heat insulating unit plate 20 is a unit plate having the structure shown in FIG. Unit board 2
When 0 constitutes the corner portion of the container, the connecting member 22 is brought into contact with the corner portion. The connecting member 22 has a structure in which the ridge portion of the angle member is recessed and the recess is filled with the heat insulating material 23. By using the connecting member 22, even the corners of the container can be efficiently heat-insulated.

FIG. 9 shows a container assembled using the heat insulating unit plate according to the present invention. The heat insulating unit plate 30 is shown in FIG.
The heat insulating unit plate 31 is different from the heat insulating unit plate 30 only in that the substrate protrudes, and in each case, the surface plate is fixed to the exterior plate by adhesion. The above-mentioned connecting member 23 is used for the corner portion of the container.

[0027]

According to the present invention, the heat insulating material is brought into contact with the entire surface of the substrate inside the box-shaped panel, the exposed surface of the heat insulating material is covered with the outer plate made of a hard material, and the outer plate is integrated with the panel. Since the heat insulating material is wrapped in the heat insulating panel, the heat insulating panel thus obtained has a good heat insulating property, and since the exterior plate reinforces the panel, the panel is hardly bent when assembled in a container. However, when trying to install a large-capacity assembly tank using a heat-insulating panel in a limited space such as in a building, since the exterior plate must be located inside the bolt holes, the heat insulating material is Since only a thin material can be used, and the heat insulating property is inferior as it is, in the present invention, a second heat insulating material is attached along with the exterior plate, and the exposed surface is covered with the surface plate. Will be good. Also, since the surface plate is adhered or bolted to the flange or exterior plate while avoiding the vicinity of the bolt hole, it does not hinder the connection of the unit plates, and after assembling the heat insulating panel into a container. However, the second heat insulating material and the surface plate can be additionally provided to form the heat insulating unit plate of the present invention. Therefore, the heat insulating unit plate of the present invention is convenient for use. The present invention provides such benefits.
