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 aims to solve the above-mentioned drawbacks by providing a male-female connection structure at the side edges in the width direction. Is provided to provide a roofing material in which a protruding piece is formed by protruding a tip of the protruding piece downward, and the protruding piece is bent upward to form a vertical piece. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a roofing material according to the present invention. 1 (a) to 1 (c),
2 (a), 2 (b), 3 (a), 3 (b), and 4
(A), (b) is explanatory drawing which shows the typical example of the roofing material A which consists of a metal roofing material B and sheet | seat C, especially FIG.
(A), (b) is an explanatory view showing a construction state and a joiner D (E is a packing material). In the drawing, α indicates a base and β indicates a fixture such as a nail. FIG. 1 (a) is the same as FIG.
1B is a cross-sectional view taken along the line bb of FIG. 2A, and FIG. 4B is an end view taken along the line cc of FIG. 3A. 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, 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. 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 is in the shape of a long plate, and one side edge in the width direction is located below the decorative surface 4, that is, on the back surface 5 side, as shown in FIG. The male connecting portion 9 is formed in a substantially U-shape to form a stepped decorative surface 6 and an insertion edge 7. The decorative surface 4, the stepped decorative surface 6 and the insertion edge 7 are formed.
A substantially U-shaped hooking groove 8 is formed from the above, and the decorative surface 4 has a protruding piece 4a that further protrudes the underwater end of the decorative surface 4;
As shown in FIGS. 1A and 1B, the projecting piece 4a is bent upward to form a vertical piece 4b. Further, as shown in FIG.
The other end of the fitting groove 10 is fitted to the insertion edge 7 which is bent upward of the decorative surface 4 and has a substantially U-shaped cross section.
Fitting edge 11 in which the front end of F.O.
A female connecting portion 13 is formed in which a fixing piece 12 is formed by bending the distal end of the fixing member 12 downward and bending outward in an L-shape substantially parallel to the decorative surface 4. At the end of the decorative surface 4, a locking piece 14 as shown in FIG.
The roofing material A is fixed on the foundation α by engaging with the engagement pieces 15 of the joiner D shown in FIG. The sheet 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 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 impregnating, containing, mixing, laminating them with sound insulation material, fireproof 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 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. The protruding piece 4a is a portion that forms a vertical piece 4b by bending upward to function as a snow stopper.
Further, it also has a function of reducing the flow velocity of rainwater flowing during rainfall and smoothing the flow of water into the rain gutter. Also, metal roofing material B processed by general roll forming
The vertical piece 4b can be formed by simple processing just by bending the protruding piece 4a. The above is only one embodiment of the roofing material according to the present invention, and FIGS. 5 (a) to 5 (c) and FIGS.
It can also be formed as shown in FIG. 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. There are features and effects.
