TECHNICAL FIELD OF THE INVENTION
The present invention relates to a roofing material having an unprecedented workability as a roofing material and having a waterproof function, a heat insulating function, a dew condensation preventing function, and the like.
[0002]
[Prior art]
2. Description of the Related Art In general, many roof materials obtained by processing a metal plate material by roll forming, press forming, or the like have been put on the market, and the shape has been a so-called hook structure. (For example, see Patent Documents 1 and 2).

[Problems to be solved by the invention]
However, since Patent Literatures 1 and 2 have a hooking structure, when used on a steeply sloping roof, the connected upper roof material falls by its own weight, so the fixing part of the upper roof material is fixed by a fixture. Until it was fixed with nails, it was necessary to hold down the roofing material by hand so that it would not fall off, and the construction was difficult.
[0005]
[Means for Solving the Problems]
In order to solve such a drawback, the present invention forms a male-female connecting structure of a drop-down structure at a side edge in the width direction, and projects an upper end of the decorative surface on the water side upward to engage and engage with a waterproof piece. It is intended to provide a roofing material formed with.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the roofing material according to the present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory view showing a typical example of a roofing material A composed of a metal roofing material B and a backing material C, FIG. 2 is an explanatory view showing a construction state of the roofing material A, and FIGS. It is explanatory drawing which shows the joiner D (E is a packing material) and the construction state. In the drawing, α indicates a base and β indicates a fixture such as a nail. FIG. 3B is an end view taken along the line aa in FIG.
[0007]
The foundation α indicates a wooden foundation composed of a rafter 1, a field board 2 and a waterproof sheet 3 (indicated by a dashed line) as shown in FIGS. 3 (a) and 3 (b) when newly constructed. That is, it is a groundwork α of a general structure in which the baseboard 2 is laid on the rafter 1 and the waterproof sheet 3 is provided on the baseboard 2. In addition, H-shaped steel, I-shaped steel, grooved steel, lightweight grooved steel, lip channel steel, equilateral angle steel, unequal angle angle steel, square steel (square pipe), circular steel (circular pipe), It is also possible to use a steel base material using such as. Of course, when the existing roof is to be repaired as it is, the existing roof structure in which an existing roof (not shown) such as a new tile or a tile rod is formed on the ground α becomes the ground α. Of course, the base α without forming the waterproof sheet 3 may be used.
[0008]
The metal roofing material B is, for example, a metal plate (a color steel plate, a copper plate, an aluminum plate, a titanium plate, a stainless steel plate, a sandwich steel plate, a clad steel plate, or the like) formed by roll forming, press forming, extrusion forming, or the like. . Of course, instead of the metal roofing material B, the roofing material A may be formed of a ceramic material, a synthetic resin material (plastic), or the like instead of the metal roofing material B.
[0009]
More specifically, the metal roofing material B has a long plate shape, and as shown in FIG. 1, a decorative surface 4 having a substantially horizontal surface, a back surface 5, and an upper surface 6 bent inward on the back surface 5 side, A male connector 9 is formed by forming an insertion edge 7 in which the tip of the upper surface 6 is bent outward and forming a substantially U-shaped engagement groove 8 from the upper surface 6 and the insertion edge 7. .
[0010]
As shown in FIG. 1, the fitting edge of the decorative surface 4 on the water-side end is fitted to the insertion edge 7 formed by bending the tip of the decorative surface 4 downward to form a substantially U-shaped cross section. The engaging groove 10, the tip of the decorative surface 4 is formed by bending upward, and the engaging and waterproofing piece 11 to be engaged with the engaging groove 8, and the fixing piece 12 further protruding from the lower edge of the fitting groove 10. The waterproof piece 13 is formed by projecting the tip of the fixing piece 12 upward, and the female connecting portion 14 is formed. 3 (b) is formed at the end of the decorative surface 4, and is locked to the engaging piece 15 of the joiner D shown in FIG. Is fixed on the base α.
[0011]
The backing material C functions as a waterproofing material, a heat insulating material, a sound absorbing material, a cushioning material, a fireproofing material, a dew condensation preventing material, and the like, and includes a nonwoven fabric, a synthetic resin foam sheet (a crosslinked foamed polyethylene sheet, etc.), rock wool. , Tex (soft fiber board), rubber sheet, resin sheet, etc., or impregnated, contained, mixed, laminated (one or more layers), sandwiched, etc., with sound insulating material, refractory material, etc. You can also. In particular, the non-woven fabric is a non-woven fabric or the like in which various fibers are bonded with an adhesive or the like, unlike the conventional method in which warp and weft cross each other to convert a fiber into a fabric. In this nonwoven fabric, the fibers intersect in parallel first, or a thin felt-like material arranged randomly is bonded with an adhesive, or another thermoplastic fiber is mixed in the main fiber state, It is made by melting under heat and pressure and bonding with each other. Of course, if the material itself does not have a waterproof property, the material is coated with a resin material, or a waterproof function is added to one or both surfaces with a water repellent, a waterproof coating agent, or the like.
[0012]
The engaging and waterproofing piece 6 is a part that bends upward to add a waterproofing function and also functions as an engaging piece.
[0013]
The protruding piece 4a is formed by bending the tip of the engaging and waterproofing piece 6 to the lower side of the water, and is a part for preventing snow from accumulating under the protruding piece 4a during snowfall and improving waterproofness. It is.
[0014]
The above is only one embodiment of the roofing material according to the present invention, and the roofing material may be formed as shown in FIGS.
[0015]
F is a reinforcing material, which is made of metal or synthetic resin.
[0016]
F is a back surface material, which is a metal material or asbestos paper, kraft paper, asphalt felt, metal foil (Al, Fe, Pb, Cu), synthetic resin sheet, rubber sheet, cloth sheet, gypsum paper, aluminum hydroxide paper, It is formed by laminating one or two or more kinds of glass fiber non-woven fabric, or a sheet or the like subjected to a waterproof treatment or a flame retardant treatment.
[0017]
【The invention's effect】
As described above, according to the roofing material of the present invention, (1) the waterproofing / engaging piece can maintain the waterproofness even when the roofing material is dropped. (2) Even when used on a steeply sloping roof, there is no need to hold down the roofing material by hand to prevent the roofing material from falling because the connected upper roofing material does not fall under its own weight. It is easy. There are features and effects.
