High heat insulation allows the energy required for heating and cooling to be saved.

[0006]

However, when such a plate-like heat insulating panel 10 is installed on a wall or the like,
There are the following problems.

That is, since the heat insulating panel 10 is made of a foamed synthetic resin such as expanded polystyrene, it may collide with other members during transportation or the like, and may be partially damaged. In particular, the corners and the like of the panel 10 are vulnerable to impact and are easily damaged partially.

However, if such a portion is damaged, a gap is formed between the column 1 and the column 1, for example, when the column 1 is brought into contact with the column 1, which causes a reduction in heat insulation. This invention has been made in view of the above circumstances, resistant to impact, and further, the gas
An object of the present invention is to provide a heat insulating panel which is excellent in tightness and heat insulating property and has good workability in mounting.

It is composed of

As a specific material of the heat insulating material 21, expanded polystyrene, expanded polyurethane, expanded polypropylene and the like are preferable. As another heat insulating material having a predetermined heat insulating performance, for example, there is a heat insulating material constructed of a quasi-incombustible or more material containing an inorganic filler. In this case, there is an advantage that not only heat insulation performance but also fire resistance performance and light weight are excellent. Further, as another heat insulating material, for example, a heat insulating material formed of acrylic resin, vinyl chloride, phenol resin, or the like may be used. The point is that any synthetic resin having heat insulation performance may be used, and the material is not limited at all. The expansion ratio is arbitrary as long as it can be handled as a plate material. For example, PVC foam expands 30 to 70 times,
Phenol foam is 20 to 40 times foaming.

Further, by appropriately setting the thickness of the heat insulating material 21 made of synthetic foamed resin, sufficient heat insulating performance can be exhibited. The cover 22 is a cover that covers only the fore-edge surface, and includes two long-side covers 22a and 22b that cover the long-side fore-end surface and short-side covers 22c and 22d that cover the short-side fore-end surface. Long side cover 2
The ends 2a and 22b are bent and have a U-shape, and the short side covers 22c and 22d are formed in a flat plate shape.

As the material of the cover 22 composed of four members, styrene, hard or semi-hard vinyl chloride, or the like is preferable as the synthetic resin. Such a panel is bonded to the heat insulating material 21 by applying an adhesive.

The heat insulating panel 20 in which the cover 22 is disposed on the fore-edge surface can be used as a wall panel as shown in FIGS. 2 and 3, for example. That is, the base 9 is provided on the foundation 8, and the through columns 14, the studs 18, and the tube columns 11 are provided on the base 9.
