Description

[Detailed Description of the Invention] The present invention relates to a unit panel of a panel assembly type heat insulating container, and has improved heat retention and durability.

In recent years, heat retention has often been required for liquid storage tanks, but in the past, it has been possible to improve heat retention by pasting heat insulating materials such as hard urethane foam on the walls of the liquid storage tank. It's getting messy. However, it has been difficult to satisfy heat retention and durability in panel-assembled containers, which are assembled by joining a large number of unit plates, each of which is shaped like a shallow box with an upright flange on the outer periphery, to satisfy heat retention and durability. .

In other words, in order to use a panel assembly type container as a heat insulating container, a heat insulating material such as hard urethane foam is usually pasted on one wall on the flange side of each unit plate until it reaches the base of the flange, and then a surface covering material is applied to the surface of the heat insulating material. are bonded to improve heat retention.

However, in the unit plate of the above structure, when the liquid is stored in a heat insulating container made by joining together a large number of unit plates,
The central part of each unit plate protrudes due to hydraulic pressure, and the heat insulating material has poor compressibility, and the deformation of the unit plate is directly transmitted to the surface covering material, so the central part of the heat insulating material and surface covering material is It tries to protrude in the direction of action. When such a phenomenon occurs, a large shearing force will be applied to each bonding surface between the unit plate and the heat insulating material, and between the heat insulating material and the surface cover material, especially at the bottom near the base of the flange of the unit plate. Peeling occurs at the adhesive surface. Therefore, it is possible to attach heat insulating material only to the central part of the unit plate where the amount of deflection is large, or to thicken the center part of the unit plate and thin the bottom part near the base of the flange. If the area of the insulation material decreases relative to the surface area, or the thickness of the insulation material on the bottom near the base of the flange is insufficient, the insulation performance of the panel will decrease, and in turn, the insulation performance of the entire container will decrease. Undesirable.

In addition, in order to avoid applying large force to the bonded parts, it is possible to reduce the deformation of the unit plates, but this requires increasing the thickness of the unit plates or using reinforcing materials, which is not economical. Not.

The present invention improves on these conventional drawbacks, and is a shallow box-shaped unit plate with a curved bottom and an upright flange around the outer periphery. A heat insulating material made of a soft foam with elastic properties is pasted on the bottom of the curved surface, and a heat insulating material made of a hard foam is attached to the bottom of the curved surface, and a surface cover material is provided to cover the surfaces of both heat insulating materials. The present invention relates to a panel for assembling a heat-insulating container.

Hereinafter, the present invention will be explained with reference to an illustrated embodiment. Fig. 1 is a partially cutaway perspective view of a panel for assembling a heat-insulating container according to the present invention, Fig. 2 is a cross-sectional view taken from Fig. 1, and Fig. 3 is a side wall of a heat-insulating container constructed by connecting the unit panels. FIG.

In the figure, 1 is a unit plate which has a shallow box shape with a flange 11 standing upright on the outer periphery of a right-angled quadrilateral, and a bottom part 12 near the base of the flange and a curved part 13 protruding from this toward the center. The bottom portion 12 is provided with a heat insulating material 2 made of elastic soft foam made of synthetic rubber or synthetic resin.
1, a heat insulating material 22 made of a hard foam having sufficient strength such as hard urethane foam is glued to the curved surface part 13, and a surface cover material 23 made of a thin plate such as PRP is glued to the surface of the heat insulating material 2. The flange 11 is provided with holes 3 for bolts, and a unit panel is thus constructed.

The above right-angled quadrilateral means a square or a rectangle,
The curved surface portion 13 may have some unevenness partially or may be flat in the center, as long as it is formed into a spherical shape as a whole. Further, it is preferable that the end portion of the surface covering material 23 is folded in the opposite direction to the flange 11.

As shown in Fig. 3, the unit panel constructed as described above is constructed by sandwiching the gasket 4 between adjacent flanges with the protruding surface of the curved portion 13 facing the outer surface of the tank, and inserting the bolt 5 into the hole 3. The tank can be assembled by threading the holes through and tightening nuts 6 to connect adjacent unit panels together. Although the above description has been made regarding a panel in which the curved surface part 13 is formed to protrude in the same direction as the flange 11, a unit panel in which the curved surface part 13 is formed in a direction opposite to the flange in a similar structure is formed to form a unit panel, and a tank is assembled. be able to.

When the tank is assembled in this way, the entire tank is covered with heat insulating material except for the flange, so
In addition to improving heat retention performance, the bottom part near the base of the panel flange is equipped with a heat insulating material made of elastic soft foam, which causes the unit plate to flex due to hydraulic pressure, which prevents the surface cover from closing. Even if a shearing force is applied to the surface cover and the bottom part near the base of the panel flange due to being drawn to the curved central part of the unit plate, the heat insulating material made of the elastic soft foam deforms as appropriate. It has the effect of improving the durability of the container by absorbing heat and eliminating peeling of the adhesive surface.Moreover, it has the effect of increasing the durability of the container. In the case where the bottom part near the base of the flange is thick and the bottom part near the base of the flange is thin, the area of the heat insulator part decreases relative to the surface area of the unit plate, or the heat insulator part near the base of the flange becomes thinner. However, according to the present invention, the bottom part near the base of the flange can also be kept warm, and the heat insulating material attached to the bottom part can be used. Since there is no need to make the unit thinner, it has the advantage that the heat retention performance of the unit plate does not deteriorate, and is of great practical benefit.
