Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has an unprecedented appearance, and has a waterproof function, a heat insulating function, a dew condensation preventing function, an enhanced snow stopping function, and the like. It relates to roofing materials. 2. Description of the Related Art Conventionally, metal roofing materials have attracted attention in terms of vibration resistance, strength, workability, and weight. However, metal roofing materials are poor in design, and there is a risk that snow on the roof will fall easily under the eaves compared to roofing materials such as tiled roofs with large irregularities. Or, a snow angle was attached to prevent snow from falling. [0003] However, since the snow stopper is attached during construction, the workability is poor.
There are drawbacks such as difficulty in construction, the risk of rain leakage if the construction is not ensured, high cost, and easy breakage. Further, the metal roofing material has a limit in workability, and it is not possible to improve the aesthetics by forming large unevenness. [0004] In order to solve the above-mentioned drawbacks, the present invention provides a decorative surface of a metal roofing material having a male-female connection structure having a hook structure formed on a side edge in a width direction. A roofing material is provided in which a vertical piece is formed by projecting a tip on a water side upward and a waterproof piece is formed by projecting a tip of a fixed piece upward. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a roofing material according to the present invention. Figure 1 shows a metal roofing material B
And FIG. 2 is an explanatory view showing a typical example of a roofing material A made of a backing material C 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. Incidentally, FIG.
It is an aa part end view of (a). The groundwork α is shown in FIGS. 3A and 3B when newly constructed.
1 shows a wooden foundation composed of a rafter 1, a ground board 2, and a waterproof sheet 3 (indicated by a dashed line).
That is, it is the 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, an existing roof structure in which an existing roof (not shown) such as a new tile or a tile rod is formed on the foundation α becomes the foundation α. Of course, the base α without forming the waterproof sheet 3 may be used. The metal roofing material B is formed, for example, from a metal plate (colored steel plate, copper plate, aluminum plate, titanium plate, stainless steel plate, sandwich steel plate, clad steel plate, etc.) by roll forming, press forming, extrusion forming or the like. Things. Of course, as the surface material of the roof material A, a metal roof material B
Instead of the above, it may be formed of a ceramic material or a synthetic resin material (plastic). More specifically, the metal roofing material B has a long plate shape, and as shown in FIG.
A vertical piece 6 protruding upward from the underwater end of the decorative surface 4, and a substantially U-shaped bend so as to open to the lower side, that is, the upper surface on the backside 5 side. An insertion edge 7 is formed, and a substantially U-shaped hooking groove 8 is formed from the decorative surface 4, the stepped decorative surface 6, and the insertion edge 7 to form a male connecting portion 9. As shown in FIG. 1, the decorative surface 4 is open at the water-side end of the decorative surface 4 on the underwater side and has a substantially U-shaped cross section.
A fitting groove 10 fitted with the insertion edge 7 formed in a letter shape,
A fitting edge 11 serving as an upper edge of the fitting groove 10, a fixing surface 12,
The female piece connecting portion 13 is formed by forming a waterproof piece 14 protruding upward from the tip of the fixing surface 12. Also, makeup face 4
3B is formed at the end of the roof material A, and the roofing material A is placed on the ground α by engaging with the engaging piece 16 of the joiner D shown in FIG. It is fixed. 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, etc., and is 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 impregnating, containing, mixing, laminating them with sound insulating material, refractory material etc.
Or a plurality of layers), a sandwich, and the like. 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 has no waterproof property, a resin material is coated, or a waterproof function is added to one or both surfaces with a water repellent, a waterproof coating agent, or the like. The vertical piece 6 is a portion that functions as a snow stopper by bending upward. The above is only one embodiment of the roofing material according to the present invention, and FIGS. 4 (a), (b) to 9 (a),
It can also be formed as shown in FIG. F is a reinforcing material made of metal or synthetic resin. G 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, hydroxide It is formed by laminating one or two or more of aluminum paper, glass fiber non-woven fabric, or the like, or is formed by a sheet subjected to a waterproof treatment or a flame retardant treatment. As described above, according to the roofing material of the present invention, the vertical piece has an unprecedented appearance, and a heavy roof can be formed. Since the vertical piece has a snow stopper function, there is no fear of rain leaking due to the construction of the snow stopper.
There is no difficult snow fitting construction. Or less.
Cost can be reduced. A vertical piece can be formed from a metal roofing material processed by general roll forming by a simple process of bending only. Since the waterproof piece protruding upward is formed at the tip of the fixed piece, rainwater or the like does not enter the base. There are features and effects.
