Description

[Detailed Description of the Invention] The present invention relates to a plate-like member for buildings, which has heat insulation and heat retention properties and is used as a roofing material or an exterior wall material of a building.

As shown in FIG. 3, such a plate-like member for a building is already in use, and is made by adhering a layer 2 of polyform urethane as a heat insulating material to one side of an iron plate or galvanized iron plate 1 with an adhesive 3. ing. However, this product was still insufficient in terms of heat insulation and heat retention.

This invention provides a plate-like member for buildings with excellent heat insulation and heat retention by stacking and fixing a rubber layer, aluminum foil, another rubber layer, and a heat insulating layer to one side of an iron plate or galvanized iron plate. This is what I am trying to do.

The present invention will be explained in detail below based on the illustrated embodiments.

In FIG. 2, reference numeral 11 is an iron plate or a galvanized iron plate (a galvanized iron plate). This iron plate or galvanized iron plate 11
An aluminum foil 13 is fixed to one side of the aluminum foil 13 via a rubber layer 12 having adhesive strength, and another rubber layer 14 having adhesive strength is attached to the surface of the aluminum foil 13.
1 layer of insulation material such as polyfoam urethane through
Fix 5.

The plate member for buildings of the present invention is formed into a folded plate, a corrugated plate, a flat plate, etc. as shown in FIG. 1, and is used as a roofing material or an exterior wall material of a building. When using this product, the iron plate or galvanized iron plate 11 side, that is, the upper side in FIG. 2 is exposed to the outside of the building.

In the present invention, each of the rubber layers 12 and 14 not only prevents heat conduction, but also
Since No. 3 reflects heat, excellent heat insulation and heat retention properties are obtained as shown in the experimental results below, and the possibility of condensation is also prevented.

<Experimental Results> The following experiment was conducted to investigate the difference in heat insulation and heat retention between the plate-like member of the present invention and a conventional plate-like member.

The plate member used in the experiment is as follows.

A plate-like member of the present invention...A rubber layer 12, an aluminum foil 13, another rubber layer 14, and a polyform urethane layer 15 are stacked and fixed on one side of a flat galvanized iron plate 11 as shown in FIG. .

Conventional plate-shaped member: A layer 2 of polyform urethane is fixed to one side of a flat galvanized iron plate 1 with an adhesive 3 as shown in FIG.

The experimental method is as follows.

Two wooden boxes without a top plate (inner volume ^18000cm3 ,
Each of the plate-like members was nailed to the top of the box measuring 30 cm long x 30 cm wide x 20 cm high and 2 cm thick, and then sealed to produce a completely sealed test box. A thermocouple was horizontally inserted 10 cm into each test box through a 5 mm diameter hole drilled in the side wall of each test box, and the hole was sealed with rubber glue. Next, each test box is placed in a thermostatic chamber, and the temperature inside the thermostatic chamber is increased from room temperature (9.4℃) to 50℃.
During this time, the temperature rise in each test box was measured at 5 minute intervals and recorded. Furthermore, after the temperature inside each test box reached approximately 50°C, the thermostat was turned off and left as it was, and the temperature drop inside each test box was measured at 5 minute intervals and recorded. These measured values are shown in FIG. In the figure, A indicates the temperature in the thermostatic chamber, B indicates the temperature in the test box to which the plate-shaped member of the present invention is attached, and C indicates the temperature in the test box to which the conventional plate-shaped member is attached. .

When the temperature A in the thermostatic chamber increases, the temperature B in the test box equipped with the plate-shaped member of the present invention is always lower than the temperature C in the test box equipped with the conventional plate-shaped member, and the temperature between the two temperatures B and C increases. The maximum difference was 8.1℃.
On the other hand, when the temperature A in the thermostatic chamber is subsequently lowered, the temperature B is maintained higher than the temperature C,
The maximum difference between temperatures B and C was 2.1°C. Therefore, it has been found that the invented plate-like member is significantly superior to conventional plate-like members in terms of heat insulation and heat retention.
