Abstract

PROBLEM TO BE SOLVED: To improve wet proofing performance by sticking an expansible wet proofing sheet to the outside of a connecting part of a heat insulating panel unit having metal plates attached to both surfaces of a synthetic resin foam plate. SOLUTION: Metal plates 1a, 1b are attached to both surfaces of a synthetic resin foam plate 2 to form a heat insulating panel unit 21. Among three synthetic resin foam plates 2a-2c for forming the synthetic resin foam plate 2, the center plate 2b is made shorter than upper and lower plats 2a, 2c to form a groove 2g, which is taken as a fitting part for a connecting member 3. The connecting member 3 has a rectangular section, and a lower metal plate 1d of the unit 21 to be put in the connecting state is superposed on a projecting part 1c of the lower metal plate 1b to be connected to each other. At this time, a sealing material 4 is filled between the whole periphery of the connecting member 3 and the groove 2g and in a joint 12, and an expansible rubber-made wet proofing sheet 5 is stuck to the outside of the connecting part to heighten performance. Even if the synthetic resin foam plate 2 is expanded and contracted in a place where a temperature change is caused, the overlapping part of the metal plates 1b, 1d can be freely moved, and performance can be kept by expansibility of the sheet 5.

There is one as disclosed in Japanese Patent Publication No. 54-54. As shown in FIG. 5, the heat insulation panel 15 has a rectangular shape in which a metal plate 14 is integrally attached to both surfaces of a synthetic resin foam plate 13.

On one short side (left side in the figure) of the metal plate 14a on the back side, the metal plate 14a is
3 and the overlapping margin 15a. On the other hand, grooves 17 are formed in both end surfaces on the long side of the synthetic resin foam plate 13, and a connecting member 16 having a rectangular cross section is fitted in the upper groove.

[0004] The construction of the heat insulating wall is performed first by using the mounting fixture 18.
Then, the heat insulating panels 15 are arranged in a plurality of stages and a plurality of stages via a connecting member, and then studs are attached, thereby improving the workability without impairing the heat insulating properties.

[0005]

However, there are the following problems in the heat insulating wall to which the above heat insulating panels are connected. 1) Moisture may enter from outside to inside of the joint part of the connection part of the heat insulating panel.

[0006] 2) Just by fitting the connecting member into the groove,
It is difficult to control the penetration of moisture. 3) If the temperature difference between the outside and the inside is large at the part that comes into contact with the outside air, such as the wall of a refrigerated warehouse or the like, the synthetic resin foam plate expands and contracts due to the temperature, and a gap is generated between the fitted connecting member and the moisture proof. The effect decreases. SUMMARY OF THE INVENTION It is an object of the present invention to provide a heat-insulating panel having improved moisture-proofing properties capable of solving the above-mentioned problems.

[0007]

According to the heat-insulating panel of the present invention, a moisture-proof sheet having elasticity is attached to the outside of a connecting portion of a heat-insulating panel unit in which metal plates are attached to both sides of a synthetic resin foam plate. It is attached.

The heat-insulating panel of the present invention has a moisture-proof property in which a sealing material is filled in a connecting portion of a heat-insulating panel unit in which a metal plate is attached to both sides of a synthetic resin foam plate.

The heat insulating panel unit has a protruding portion for superimposed connection with a metal plate on one side. Further, the connection of the heat insulation panel unit is made via a connection member.

The heat insulation panel unit is connected via a connecting member, and the heat insulation panel unit is provided with a protruding portion for superimposition connection on a metal plate on one surface. Then, a concave portion is formed at an end of the resin plate on the lower side of the heat insulation panel unit on the other side to be connected,
The end of the lower metal plate is bent along this recess.

[0011]

FIG. 1 shows an example of an embodiment of the present invention.
This will be described below. The heat insulation panel unit 21 is configured by attaching metal plates 1 a and 1 b to both surfaces of a synthetic resin foam plate 2. Then, the lower metal plate 1b is overlapped with the adjacent heat insulation panel unit 21 to form a sliver protrusion 1c.
have.

The synthetic resin foam plate 2 is a synthetic resin foam plate 2
a, 2b, 2c. The central plate 2b is shorter than the upper and lower plates 2a, 2c. Thus, a groove 2g serving as a fitting portion of the connecting member 3 is formed.

The connecting member 3 is a member for connecting adjacent heat insulating panel units 21 and has a rectangular cross section. Then, when connecting the heat insulation panel units 21 to each other, as shown in FIG. 2, the lower metal plate 1d of the unit 21 to be connected is overlapped and connected to the protruding portion 1c of the lower metal plate 1b.

At this time, the sealing material 4 is filled between the entire circumference of the connecting member 3 and the groove 2g, and the joint 12 is also filled with the sealing material 4 and connected. Then, an elastic rubber moisture-proof sheet 5 is attached to the outside of the connecting portion.

Next, another connection and joining state of the heat insulating panel unit are shown in FIG. In this case, an end recess of the lower resin plate 2d to be connected to the opposite panel unit 21 is formed, and the end of the metal plate 1e is bent along the recess.

Thus, the protruding end 1c of the metal plate 1b is
The metal plate 1e and the metal plate 1
Since the lower surfaces of b and b are on the same plane, the elastic moisture-proof sheet 5 made of rubber can be stuck straight on the metal plate, and the sheet hardly comes off even if the panel unit expands and contracts.

Next, the mounting state of the heat insulating panel and the outer wall will be described with reference to FIG. The angle 6 protrudes from the upper surface of the upper metal plate 1 a of the panel 21. For example, a prism 7a is mounted inside the angles 6,6. On the other hand, the upper surface 1 of the outer wall 11
For example, a prism 7b is attached to a position 1a corresponding to the prism 7a. Then, for example, H is placed between the prisms 7a and 7b.
Attach the post 9.

Then, a heat insulating layer 9 such as urethane foam is sprayed around the H-shaped column 9. Further, since it is impossible to attach a moisture-proof sheet over the long distance without damaging the moisture-proof effect over the heat-insulating panel 20 and the prism 7b, the sprayed moisture-proof layer 10 such as a hull coat and the like are used. Spraying with the top.

【The invention's effect】

1) Due to the configuration in which the metal plates on one side of the heat-insulating panel unit are overlapped and connected, moisture does not easily enter. And
By attaching a stretchable moisture-proof sheet to the overlapping connection portion, the moisture-proof performance is enhanced.

2) Even if the synthetic resin foam board is expanded and contracted when used in a place where the temperature changes, the overlapping portion of the metal plate can move freely, and the moisture-proof sheet has elasticity, so that the moisture-proof property is always maintained. Will be maintained.

3) The configuration in which the metal plates are overlapped and the heat insulating panels are connected facilitates positioning when the heat insulating panels are built, and the self-sustainability is enhanced. 4) Even if the moisture-proof sheet is broken, the sealing material is filled around the connecting member, so that the moisture has an effect of delaying the time of infiltration through the joint, and the moisture-proof property can be maintained for a long time.

5) A recess is formed at the end of the lower resin plate on the other side of the heat insulating panel unit to be connected, and the end of the lower metal plate is bent along this recess to be connected. Since the lower surface of the metal plate is flush with the metal plate, the moisture-proof sheet can be stuck straight on the metal plate, and the sheet does not easily come off even if the panel unit expands and contracts.
