DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a backing sheet mainly attached to the back surface of a metal-based exterior material used for buildings for heat insulation and fire prevention, and a metal-based exterior material attached to the backing sheet.

[0002]

2. Description of the Related Art Metallic exterior materials used for buildings and the like are:
As a backing sheet, a structure in which a resin-based foam sheet having flexibility and elasticity is backed for the purpose of heat insulation and prevention of dew condensation is generally known. In recent years, as the backing sheet, a sheet in which fire resistance is added to properties such as heat insulation, bendability, and elasticity is used. Since the backing sheet has flexibility and elasticity, as shown in FIG. 2 of Japanese Patent Publication No. 5-71377, the metal material is a coil or a flat plate (strip).
And then subjected to folding forming (roll forming) of the exterior material. Both backing and bending can be easily and automatically performed by a general-purpose device. In this way, by back-applying to the metal-based exterior material (metal material) before bending and forming, it is not necessary to apply the backing manually by hand after molding of the exterior material, which is high in both factory production and on-site molding. Productivity is obtained, resulting in cost reduction. Conventionally, the general thickness of this kind of backing sheet is 4 to 5 mm, but in recent years, in order to further improve the heat insulation performance and the sound absorbing performance, a thick backing sheet of about 8 to 10 mm has been used. There is a demand for a backing exterior material. On the other hand, as for the exterior material itself, an elastic fitting type exterior material is demanded in order to improve on-site workability and designability.

[0003]

However, when a backing sheet that is thicker than a conventional general product is used for a conventionally known exterior material, it is made of polyethylene foam (PEF).
Even if it is a resin sheet represented by, the compressive strength increases compared to the general surface, so unless it is a corrugated exterior material of a very simple shape such as a polymerization / bolting method, a predetermined design at the time of molding A shape cannot be obtained, or a predetermined connection mode cannot be obtained at the time of construction. Particularly, in the case of the elastic fitting type exterior material, the peripheral shape of the fixing portion is complicated and higher dimensional accuracy is required as compared with the bolting type or the engagement type exterior material because of the fixing (holding) method. You. Therefore, in many cases, it is impossible to obtain a predetermined shape, and even if it is obtained, a large amount of time is required for adjusting a molding machine, and productivity is significantly reduced. Furthermore, even if a predetermined shape is obtained, the dimensional accuracy of the exterior material can be obtained when the fixing (holding) tool of the exterior material such as a tight frame comes into contact with the surface at the time of construction or when the side edges are abutted or polymerized. It is in the same state as not being, the predetermined fitting form can not be obtained, the fitting is partially loose, or distortion occurs,
In the first place, fitting cannot be performed. Further, when the backing sheet is a general product of an inorganic fiber sheet typified by glass wool, since it originally has the same forming characteristics as the thick material of the resin sheet, a very simple waveform such as a bolting method is used. Except for the exterior material, after molding the exterior material,
There is a situation in which the backing is performed manually by avoiding the fitting portion and the overlapping portion.

[0004]

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above, and is directed to a backing sheet to be backed on a metal-based exterior material before bending and forming, at least having heat insulating properties, elasticity, and bendability. A backing sheet comprising: a thin portion along the bent portion and / or the overlap portion of the exterior material; and a thick portion along the portion other than the bent portion and / or the overlap portion of the exterior material. In addition, a metal-based exterior material backed with this is proposed. In addition, the metal-based exterior material of the present invention (hereinafter referred to as exterior material) is a vertical-roofed roofing material or a vertically-extended outer wall material used for a roof or an outer wall of a building, and more specifically, a tile rod, a folded plate Siding.

For example, closed cells such as inorganic high-filled foam, highly flame-retardant polyethylene foam, and cross-linked foamed polyethylene are used. Based foam sheet (apparent density about 0.025-0.05g / cm
3) or an inorganic fiber sheet (approximately 0.13 g / cm 3) such as a glass fiber non-woven fabric. The elasticity and bendability may be at least such that the backing sheet can be bent and formed without any trouble in a state where the backing sheet is backed on an exterior material (metal material). Also,
When the resin-based foam sheet is used as the backing sheet, the thin portion is preferably about 3 or 4 mm, which has been confirmed to be most frequently used in the conventional exterior material and has been confirmed to have no trouble in molding. The thickness of the portion is not particularly limited as long as it is thicker than the thin portion, but it is preferably about 8 to 10 mm or more. Incidentally, the thickness of a general PEF is 4 mm. On the other hand, when the inorganic fiber sheet is used as a backing sheet, its thin portion is 2.5 m
m is preferable, and the thick portion is 8 to 10 m.
m or more. Therefore, the thickness of the thin portion in the backing sheet of the present invention is preferably １ ／ or less of the thickness of the thick portion.
