2. Description of the Related Art Conventionally, a cement-based board has been coated with a water-resistant and weather-resistant paint, and the paint color is often dark, with no noticeable dirt. After the construction, the cement-based board is exposed to direct sunlight. However, there is a problem that radiant heat from the heated cement-based plate material spreads to the ceiling and heats the attic.

[0003] In addition, when a cement-based plate is laid on a roof base such as a control panel, when the cement-based plate is positioned on the roof base and nailing is performed at a nailing portion, the heated plate is heated. Heat is transferred from the underside of the roof like a control panel to the cement-based plate material side,

By reflecting the radiant heat from the cement-based plate material 1 toward the attic, it is possible to suppress a rise in the temperature of the attic, and when the cement-based plate material 1 is laid on the roof base 7 such as a control panel, When the cement-based plate 1 is positioned on the roof base 7 and nailing is performed at the nailing portion, heat is transferred from the roof base 7 such as a heated control panel to the cement-based plate 1. Can be effectively suppressed, and the cement-based plate material 1 can be prevented from being heated and the soles of the workers can be prevented from being heated. Therefore, moisture can be prevented from entering from the end face of the inorganic heat insulating plate 3 such as the gypsum board 2, and the heat insulating function of the inorganic heat insulating plate 3 can be maintained for a long time.

Further, the gypsum board 2 can be cut while the heat insulating property and the sound absorbing property can be sufficiently maintained by the gypsum board 2.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. 1A shows a schematic front view of the roofing material A, FIG. 1B shows a cross-sectional view, and FIG. 1C shows an enlarged cross-sectional view. The roofing material A is provided with an inorganic heat insulating plate 3 on the back surface of a cement-based plate material 1 formed in a substantially pentagonal shape with the ridge side as the top.
Are laminated with a heat-insulating reflector 5 whose entire surface including the peripheral end surface is covered with a metal foil 4. The inorganic heat insulating plate 3 is a paper material 6 that has been subjected to a water-resistant treatment as a water-resistant sheet 6 that can be cut except for both end surfaces in a direction orthogonal to the ridge eaves direction of the gypsum board 2.
a. The inorganic insulating plate 3 in which the paper material 6a subjected to the water-resistant treatment is wound around the gypsum board 2 is a brand name “fireproof board” manufactured by “Yoshino Gypsum Co., Ltd.”, for example, the inorganic insulating plate 3 is made of wood wool cement. Other specifications may be acceptable.

The heat insulating board 3 using the above-mentioned "fireproof board" is covered with an aluminum foil as a metal foil 4 on the entire surface including the peripheral end face, and is adhered with a silicon-based adhesive to form a heat insulating reflection plate 5. It constitutes. The heat insulating reflection plate 5 is bonded to the back surface of the cement-based plate material 1 with the above-mentioned silicone-based adhesive to form the roof material A. As described above, in the roofing material A, the heat insulating reflection plate 5 in which the inorganic heat insulating plate 3 is entirely covered with the metal foil 4 including the peripheral end surface is laminated on the back surface of the cement-based plate material 1. As shown in FIG. 2, a roof is laid on a roof base 7 such as a control panel laid on a rafter 8 via a roofing 9 as necessary. Roofing is a well-known construction method in which nailing is performed in the nail hole 10.

However, when the cement-based plate 1 is heated to a high temperature by irradiation of sunlight after the construction,
The radiant heat from the cement-based plate material 1 toward the attic is reflected by the heat-insulating reflector 5 laminated on the back surface of the device, and the temperature rise on the attic side is suppressed. When the cement-based plate 1 is laid on a roof base 7 such as a control panel, when the cement-based plate 1 is positioned on the roof base 7 and nailing is performed at a nailing portion,
The heat-insulating reflector 5 lined with the back surface of the cement-based plate material 1 effectively suppresses heat transfer from the roof base 7 side such as a heated control panel to the cement-based plate material 1 side. This prevents the cement-based plate 1 from being heated and the sole of the worker from being heated.
Moreover, the peripheral surface of the inorganic heat insulating plate 3 is also covered with the metal foil 4 to prevent moisture from entering from the end surface of the inorganic heat insulating plate 3 such as the gypsum board 2, and the heat insulating function of the inorganic heat insulating plate 3 is extended. Can be maintained over time.

Further, the inorganic heat insulating plate 3 is covered with a water-resistant sheet 6 that can be cut except for both end faces in a direction perpendicular to the direction of the eaves of the gypsum board 2, and the gypsum board 2 provides heat insulation and sound absorption. Gypsum board 2 while maintaining the
Is surrounded by a water-resistant sheet 6 that can be cut, and is covered with a metal foil 4 from above. Such a heat-insulating reflector 5 can be easily formed by cutting the metal foil 4 and the water-resistant sheet 6 with a cutter. Can be cut at the point of, for example,
When the roofing material A is cut on the roof with a tile cutter, the cement-based plate 1 and the heat-insulating reflecting plate 5 are simply cut into the insulating reflecting plate 5 with the cutter or the like as described above.
Can be easily cut, and even if the heat insulating reflection plate 5 is provided on the back surface, the cutting of the cement-based plate 1 is not hindered.

[0013]

According to the first aspect of the present invention, a waterproof sheet capable of cutting a gypsum board is provided on the back surface of the cement-based plate material .
Since the heat-insulating reflector is constructed by covering the entire surface, including the end surface of the peripheral part, with metal foil, the cement-based sheet material is heated to a high temperature by irradiation with sunlight after construction. When it is done, the heat-insulating reflector laminated on the back of the cement-based plate reflects the radiant heat from the cement-based plate toward the attic, and can suppress the temperature increase on the attic side, and furthermore, the cement-based When laying a plate material on a roof base such as a control panel, when positioning a cement-based plate on the roof base and performing nailing at the nailing part, a roof base such as a heated control panel It is possible to effectively suppress the heat transfer from the side to the cement-based plate material side, and to prevent the cement-based plate material from being heated and the sole of the worker from being heated. However, since the peripheral surface of the inorganic heat insulating plate is also covered with metal foil, it prevents moisture from entering from the end surface of the inorganic heat insulating plate such as gypsum board, and the heat insulating function of the inorganic heat insulating plate can be maintained for a long time. There is an advantage.

Furthermore, since the gypsum board is covered with a cuttable waterproof sheet, the gypsum board is surrounded by the waterproof sheet while the heat insulation and sound absorption properties can be sufficiently maintained by the gypsum board. Such a heat-insulating reflector can be easily cut at a desired location by cutting the metal foil and the water-resistant sheet with a cutter. When cutting with a cutter, just cut the heat insulating reflector with a cutter or the like as described above, the cement-based plate and the heat insulating reflector can be easily cut, and the heat insulating reflector is provided on the back side. This does not hinder the cutting of the cement-based plate.
