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).

Japanese Patent Application Laid-Open No. 2002-038658 [Patent Document 2]
Japanese Patent Application Laid-Open No. 2002-155602
[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 provides a waterproof piece having a decorative surface with a water-side tip projecting upward, a fitting piece having a waterproof piece with a tip projecting upward, and a water-resistant piece having a decorative surface having a water tip facing water. Roofing material that forms a fixed piece that protrudes to the side and forms an innermost piece that protrudes downward near the tip of the decorative surface on the underwater side, and an insert piece that protrudes the tip of the innermost piece downward. To provide.
[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. FIGS. 2A and 2B are explanatory views showing a construction state of the roofing material A, and FIG. (a), (b) 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 ground board 2, and a waterproof sheet 3 (indicated by a dashed line) as shown in FIGS. 2A and 2B 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 is in the shape of a long plate, and as shown in FIG. 1, the decorative surface 4, the back surface 5, the front end 6 of the decorative surface 4, and the front end 6 The upper surface 7 protrudes inward along 4, the innermost piece 8 whose tip of the upper surface 7 protrudes downward, the insertion piece 9 whose tip of the innermost piece 8 protrudes below the water, and the upper surface 7. A substantially U-shaped engagement groove 10 is formed from the innermost piece 8 and the insertion piece 9, the tip of the insertion piece 9 is bent in a goby shape to form a tongue piece 11, and It was done.
[0010]
As shown in FIG. 1, a waterproof piece 13 formed by bending the tip of the decorative face 4 upward at the water-side end of the decorative face 4, and a fitting in which the tip of the waterproof piece 13 projects to the water-side. A piece 13a, an upper surface 14 with the tip of the fitting piece 13a protruding below the water, a fixing piece 15 with a tip of the upper surface 14 protruding above the water, and a substantially U-shaped cross section from the upper surface 14 and the fixing surface 15. A female connecting portion 17 is formed by forming a fitting groove 16 for fitting with the formed insertion piece 9. 3 (b) is formed at the end of the decorative surface 4, and is locked to the engaging piece 19 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 waterproofing piece 13 is a part that bends upward to add a waterproofing function and also functions as a part of the fitting piece 13a.
[0013]
The above is only one embodiment of the roofing material according to the present invention, and it can be formed as shown in FIGS. 4 (a) to 4 (c) to 6 (a) and 6 (b).
[0014]
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.
[0015]
【The invention's effect】
As described above, according to the roofing material of the present invention, (1) the waterproofness can be maintained even if the fitting piece formed with the waterproofing piece drops the roofing material to form a structure. (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. {Circle around (3)} Since the upper end of the water on the decorative surface and the fixing piece are formed at the same level, the step may be small and there is no deformation due to the load on the connecting portion. There are features and effects.
