Description

[Detailed Description of the Invention] This invention relates to a unit plate used for assembling an insulated tank.

It is already practiced to assemble large containers such as tanks from a large number of veneer plates. As such a unit board, a shallow box-shaped body is widely used, which is formed by using a rectangular rectangular board made of a single board as a board, and providing bonding edges around the four peripheries of the board. This unit plate was made of iron or synthetic resin. but,
Regardless of whether it is made of iron or synthetic resin, this unit plate easily conducts heat, so it is necessary to keep the temperature inside the tank constant or to prevent condensation from forming on the tank wall. In some cases, it was necessary to improve the insulation properties of the unit plates.

In order to meet this need, a three-layer structure has been developed in which a heat insulating material is brought into contact with the entire surface of a single board forming a board, and a board is stacked on top of the heat insulating material to form a three-layer structure, which is used as a unit board. Tanks assembled from such unit plates certainly had excellent insulation properties. However, such tanks assembled only from unit plates had other drawbacks. The disadvantage is that in order to provide a liquid inlet/outlet to this tank, three
When holes are drilled in a unit plate with a layered structure, the heat insulating material is exposed on the surface of the hole, and the liquid in the tank enters the exposed heat insulating material, impairing the heat insulation properties.

In order to improve the above drawbacks, this inventor
The idea was to leave a veneer part in a part of the board in the unit board and drill holes there. Also,
At the boundary between the single-panel section and the three-layer panel section, the edge of the insulation material is exposed and rainwater can enter the insulation material from there, so we considered covering this edge with a strip. Furthermore, since the unit plate with the single plate portion left is more flexible than the unit plate with the overall three-layer structure that constitutes the other parts of the tank,
The idea was to have the side edges and both ends of the above band plate integrally fixed to the veneer and the joint edge, respectively, and to make the band plate function as a rib. This idea was made based on this idea.

In other words, this idea uses a shallow box-shaped unit board with a rectangular rectangular board made from a veneer and joint edges around the four peripheries of the board, leaving the veneer part in a part of the board and attaching the remaining part. The insulation material and the veneer are brought into contact with each other to form a three-layer structure, and a strip plate is provided between the third layer and the veneer section to cover the edge of the insulation material, and the strip or its extension is attached to one side of the board. Alternatively, it is a unit plate for tank assembly, which exists continuously from one corner to another side or corner, and the side edges and both ends of the strip plate are integrally fixed to the single plate and the joint edge, respectively.

The unit plate for tank assembly according to this invention will be explained as follows based on the drawings. 1 to 19 are partially cutaway perspective views showing an example of a unit plate for tank assembly according to this invention. FIGS. 20 to 22 are partially cutaway perspective views showing an example of how the unit plate for tank assembly according to the invention is used.

In FIG. 1, a right-angled quadrilateral made from a veneer 11 is provided with bonding edges 2 around the four peripheries of the substrate 1.
It consists of shallow box-shaped unit plates. In this unit board, a veneer portion is left in a part of the substrate 1, and a heat insulating material 3 and a veneer 4 are brought into contact with the remaining part, resulting in a three-layer structure. A band plate 5 covering the edge of the heat insulating material 3 is provided at the boundary between the three-layer part and the single plate part. Band plate 5
exists continuously from one side 12A of the substrate 1 to the other side 12B. The side edges of the band plate 5 are integrally fixed to the veneers 11 and 4, and both ends of the band plate 5 are integrally fixed to the joining edge 2 along the sides 12A and 12B. What is thus constructed is the tank assembly unit plate a according to this invention.

In the above unit plate a, the single plates 11 and 4 are preferably plates made of reinforced synthetic resin (for example, glass fiber reinforced polyester resin), but metal plates such as iron plates can also be used. The veneer may have an uneven pattern. As the heat insulating material 3, a foamed board such as hard urethane foam or acrylic foam, a plywood board, a fiberboard, etc. are used. Preferably, the heat insulating material 3 occupies at least one third of the area of the veneer 1. The side on which the heat insulating material 3 and the veneer 4 come into contact may be the protruding side of the joint edge 2 as shown in FIG. 1, or may be the opposite side.

The joining edge 2 may be upright with respect to the open surface of the substrate or the box, or may be inclined, for example, at an angle of 135 degrees. The strip plate 5 is connected to the veneer 11.
It is preferable to stand at an angle of 45 to 135 degrees. The strip plate 5 may be continuous from one corner of the substrate 1 to another corner, or may be continuous from one side to a corner not included therein. Also, it may be curved in the middle. The joint edge 2 and the strip 5 are preferably made of the same material as the veneer.

As mentioned above, this invention includes various embodiments other than those shown in FIG. 1, the main ones of which will be explained below. In addition,
In the following description, description of the same parts as in the preceding drawings will be omitted.

In the unit plate e for tank assembly according to this invention shown in FIG. 5, the single plates 11 and 4 each have a circular or semicircular protruding pattern.

In the tank assembly unit plate f according to this invention shown in FIG. 6, the strip plate 5 is continuous between two adjacent sides.
Further, the heat insulating material 3 and the veneer 4 are provided with a small circular depression 6. This depression 6 is used as a place for fixing something such as a stay bolt or a support.

In the tank assembly unit plate g according to this invention shown in FIG. 7, the joining edges 2 along two adjacent sides of the substrate 1 are
It is composed of an upright joint edge 2A and an inclined joint edge 2B.

In the unit plate h for tank assembly according to this invention shown in FIG. 8, the single plates 11 and 4 are provided with a cross-shaped protruding pattern. In addition, in this unit plate h, all the joining edges 2 are inclined with respect to the opening surface.

In each of the unit plates i to n for tank assembly according to this invention shown in FIGS. 9 to 14, a heat insulating material 3 and a single plate 4 are brought into contact with the four corners of the substrate 1. In unit plate i in FIG. 9 and unit plate k in FIG. 11, adjacent heat insulating materials or veneer plates 4 are in contact with each other at the corners. Note that in the unit plate i, the heat insulating material and the veneer are in contact with the inside of the box-shaped body, and in the unit plate k, they are in contact with the outside.

In unit plate k in FIG. 10, unit plate l in FIG. 12, unit plate m in FIG. 13, and unit plate n in FIG. 14, adjacent heat insulating materials and veneers are separated from each other. In addition, in the unit plates l and n, the strip plate 5 is bent so as to bulge toward the center of the substrate 1. Further, in the unit plate m, the central portion of the strip plate 5 is bent so as to bulge toward the corner side of the substrate 1, and the vicinity of both ends are bent. Furthermore, the center of the veneer 11 is circularly depressed, and a hole 7 is bored in the center of the depression. This hole is used as a liquid inlet and outlet.

In each of the unit plates o to s for tank assembly according to this invention shown in FIGS. 15 to 19, the strip plate 5 is extended through the inside of the heat insulating material 3, and
reaches one side or corner of the substrate 1 and is fixed there. In addition, the unit plate o in Fig. 15
In this case, the strip plate 5 and its extension portion 51 exist continuously between two opposing sides of the substrate 1.

Unit plate p in Fig. 16 and unit plate q in Fig. 17
In this case, the strip plate 5 and its extended portion 51 are continuously present between two adjacent sides of the substrate 1, and the adjacent extended portions 51 are in contact with each other on the joining edge 2.

In the unit plate r shown in FIG. 18, the strip plate 5 and its extension portion 51 are continuously present on the diagonal of the substrate 1.

In any of the above, the strip plate 5 and its extension portion 51
stands upright from the veneer 11. On the other hand, in the unit plate s of FIG. 19, the strip plate 5 and its extension 51
are inclined with respect to the veneer 11.

The unit plate for tank assembly according to this invention is mainly used for assembling the side wall of the tank, but can also be used for assembling the bottom or the lid. When used to assemble the bottom, the single plate part of the board is used not only as a mounting part for a drain pipe but also as a seat for installing a machine such as a submersible pump. When used on side walls and lids, it is used as a mounting part for water supply pipes, drain pipes, etc.

The method of using the unit plate for tank assembly according to this invention will be explained as follows based on the drawings. In FIG. 20, the side wall of the tank is assembled using unit plates a, c and d according to this invention.
A hole 7 is bored in each of the single plate portions of these unit plates, and a flange portion 72 of a flanged tube 71 is fixed around the hole 7. When fixing, it is desirable to sandwich a gasket between the flange portion 72 and the veneer 11. Further, a water supply pipe 73 with a ball tap is fixed to the single plate portion of the unit plate d. Note that a heat insulating material 74 is placed in contact with the veneer portion around the hole 7, and a veneer 75 is placed on top of the heat insulating material 74, which extends over the three-layer portion and the joint edge.
It can be covered with It is desirable to apply a filler material 76 such as putty to the edge of the veneer 75.

In FIG. 21, the bottom of the tank is assembled using the unit plate t according to this invention. unit plate t
In the unit plate f of FIG. 6, the band plate 5 is curved in an arc shape. A hole 7 is bored in the single plate portion of the unit plate t, and serves as a drain hole.

In FIG. 22, the side wall of the tank is assembled using unit plates a, b, g and r according to this invention. As in the case of FIG. 20, holes are formed in the single plate portions of these unit plates, and the flange portions 72 of the flanged tubes 71 are fixed around the holes. Note that in this figure, an inclined joining edge 2B is used to connect two unit plates in an orthogonal state.

The unit plate for tank assembly according to this invention is a shallow box-shaped unit plate in which the substrate is a right-angled quadrilateral made of a veneer, and joint edges are provided around the four peripheries of the substrate. Since the insulation material and the veneer are in contact with the remaining part to create a three-layer structure, if the veneer part is used to attach a liquid inlet/outlet to the tank, there is a risk that the liquid in the tank may enter the insulation material. There is no. Furthermore, since there are three layers, the heat insulation performance of the tank does not deteriorate excessively. Furthermore, since a band plate is provided at the boundary between the three-layer part and the single-panel part to cover the edge of the heat insulating material, rainwater and the like can be prevented from entering through the edge of the heat insulating material. Moreover, the strip or its extension can be attached to one part of the board.
Since it exists continuously from one side or corner to the other, and the side edges and both ends of the strip are integrally fixed to the veneer and the joint edge, the strip acts as a rib, resulting in a unit This prevents the board from bending. This idea has a number of advantages, as mentioned above.
