Description

  The present invention relates to a roofing material that has an unprecedented appearance and that has a waterproof function, a heat insulating function, a dew condensation prevention function, a snow stop function enhancement, and the like.

  In general, a large number of roofing materials obtained by processing metal plate materials by roll molding, press molding, and the like have been put on the market, and metal roofing materials have been attracting attention in terms of vibration resistance, strength, workability, and weight. However, the metal roofing material was poor in design. (For example, refer to Patent Documents 1 and 2). In addition, compared to roof materials such as tile roofs with large irregularities, there is a risk that the snow on the roof can easily fall under the eaves, and the roof structure using a roof material with a snow stop function added to the roof material itself Has been developed. (For example, refer to Patent Documents 3 and 4).

  However, since the snow stoppers are attached during the construction, (1) the construction is poor, (2) the construction is difficult, (3) if the construction is not ensured, it will cause rain leakage, (4) high cost (5) There was a fault, such as being easy to break. Moreover, the metal roofing material has a limit in workability, and the aesthetics cannot be improved by forming large unevenness.

  In order to solve such a drawback, the present invention hangs down the water-side tip of the decorative surface of the metal roofing material having a male-female connection structure on the side edge in the width direction, The roof material which protruded in the side, formed the protrusion piece, and formed the wave shape in the protrusion piece is provided.

  According to the roofing material according to the present invention, (1) it is possible to form a heavy roof with an unprecedented appearance of undulations. (2) Since the wavy shape has a snow stop function, there is no risk of rain leakage due to snow stop fittings. (3) There is no difficult snow clamp construction. (4) Cost can be reduced. (5) A corrugated metal roofing material processed by general roll forming can be formed by simple processing only by bending. There are features and effects.

  The roof material according to the present invention will be described in detail below with reference to the drawings. 1 (a) to 1 (c), FIG. 2, FIG. 3 (a), (b), and FIGS. 4 (a) and 4 (b) are representative roof materials A made of a metal roof material B and a sheet C. FIG. It is explanatory drawing which shows an example, and especially FIG. 4 (a), (b) is explanatory drawing which shows a construction state and Joiner D (E is a packing material). In the figure, α indicates a base, and β indicates a fixture such as a nail. 1A is an end view taken along the line aa in FIG. 2, FIG. 1B is a sectional view taken along the line aa in FIG. 2, and FIG. 1C is a sectional view taken along the line bb in FIG. FIG. 4B is an end view of the cc portion of FIG.

  The base α indicates a wooden base composed of a rafter 1, a field plate 2, and a waterproof sheet 3 (indicated by a one-dot chain line) as shown in FIGS. 3 (a) and 3 (b). That is, it is a base α having a general structure in which a base plate 2 is laid on the rafter 1 and a waterproof sheet 3 is disposed on the base plate 2. In addition, as base α, H-shaped steel, I-shaped steel, grooved steel, lightweight grooved steel, lip groove shaped steel, equilateral angled steel, unequal angled angled steel, square steel (square pipe), round steel (circular pipe), It is also possible to use a steel base using, for example. Of course, when the existing roof is refurbished 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 base α is the base α. Of course, the base α on which the waterproof sheet 3 is not formed may be used.

  The metal roof material B is formed by roll forming, press forming, extrusion forming, or the like of a metal plate (color steel plate, copper plate, aluminum plate, titanium plate, stainless steel plate, sandwich steel plate, clad steel plate, etc.), for example. . Of course, as a surface material of the roof material A, instead of the metal roof material B, it may be formed of a ceramic material, a synthetic resin material (plastic), or the like.

  More specifically, the metal roof material B has a long plate shape, and as shown in FIG. 1 (c), one side edge in the width direction is substantially U-shaped on the lower side of the decorative surface 4, that is, on the back surface 5 side. It is made into the male type | mold connection part 9 which bent into the shape and formed the level | step difference decorative surface 6 and the insertion edge 7, From the decorative surface 4, the level | step difference decorative surface 6, and the insertion edge 7, it is a substantially U-shaped hook groove. 8, a protruding piece 4 a that further protrudes the water-side tip of the decorative surface 4 on the decorative surface 4, and a protruding piece 4 a that is bent upward as shown in FIGS. 1B and 1C. 4b is formed.

  Further, as shown in FIG. 1 (a), the fitting groove 10 is fitted at the other end of the decorative surface 4 to be fitted to the insertion edge 7 bent to the upper side of the decorative surface 4 to have a substantially U-shaped cross section. And a fitting edge 11 in which the tip of the fitting groove 10 is folded back in a U-shape, and a tip of the fitting edge 11 is bent downward and bent outwardly in an L-shape substantially parallel to the decorative surface 4. A female connecting portion 13 in which an extended fixing piece 12 is formed is formed. Further, a locking piece 14 as shown in FIG. 4 (b) is formed at the end of the decorative surface 4 and locked to the engaging piece 15 of the joiner D shown in FIG. Is fixed on the base α.

  Sheet C functions as a waterproof material, heat insulating material, sound absorbing material, shock absorbing material, fireproof material, anti-condensation material, etc., non-woven fabric, synthetic resin foam sheet (crosslinked foamed polyethylene sheet, etc.), rock wool, It is also possible to use tex (soft fiber board), rubber sheet, resin sheet, etc., or impregnated, contained, mixed, laminated (single layer or multiple layers), sandwich, etc. it can. 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 a conventional method in which warps and wefts are crossed to form a woven fabric from fibers. In this nonwoven fabric, fibers are crossed in parallel, 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 by heating and pressing and bonding them together. Of course, if the material itself is not waterproof, a resin material is coated, or a waterproof function is added to one or both sides with a water repellent, a waterproof coating agent, or the like.

  The protruding piece 4a is a part that forms a corrugated shape 4b by being partially bent and functions as an improvement in design and as a snow stop. It also has the function of reducing the flow rate of rainwater that flows during rainfall and smoothing the water flow to the rain gutter. Further, the corrugated 4b can be formed by a simple process of bending the protruding piece 4a (pressing or the like) from the metal roofing material B processed by general roll forming.

  The above description is only one example of the roofing material according to the present invention, and it can be formed as shown in FIGS. 5 (a) to (c) to FIGS. 10 (a) and 10 (b).

  Since it can be used as a wall material, the range of use is wide.
