Description

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

  In general, many roofing materials obtained by processing metal plate materials by roll molding, press molding, etc. 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 compared to the tile roof. (For example, refer to Patent Documents 1 and 2). Also, 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 body 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 could not be improved by forming large irregularities. In addition, since Patent Documents 1 and 2 have a hook structure, when used on a roof with a steep slope, the connected upper roof material falls by its own weight, so the upper roof material fixing part is fixed to the fixture. Until it was fixed with (nails), it was necessary to hold it by hand so that the roofing material did not fall, and the construction was difficult.

  In order to solve such a drawback, the present invention provides a roofing material in which a male-female connecting structure having a dropping structure is formed on the side edge in the width direction, and the tip of the underside of the decorative surface of the roofing material is on the underwater side. The roof material which protruded and formed the protrusion piece and bent the protrusion piece partially and formed the recessed part is provided.

According to the roofing material which concerns on this invention, (1) Even if the fitting piece which formed the 1st waterproofing piece and the 2nd waterproofing piece dropped down the roofing material, waterproofness can be maintained. (2) Even if it is used on a steep roof, the connected upper roof material does not fall under its own weight, so there is no need to hold it down by hand so that the roof material does not fall. It is easy. (3) Since the water upper end portion of the decorative surface and the fixed piece are formed at the same level, the step may be small, and there is no deformation due to the load of the connecting portion. (4) When the upper roof material is applied to the lower roof material, the second waterproof piece of the lower roof material contacts the upper surface of the upper roof material, and the second waterproof piece always springs in the engagement groove. It exhibits a back effect and improves waterproofness and airtightness. (5) The formation of the second waterproof piece cancels out the opposing forces in the connecting portion between the roof materials, so that the roof material is not destroyed or the fixture formed on the fixed piece does not fall out of the ground. The material is not peeled off by the wind. (6) The concave portion has an unprecedented appearance and can form a heavy roof. (7) Since the concave portion has a function of preventing snow, there is no fear of rain leakage due to construction of the snow stopper. (8) There is no difficult snow stop construction. Or less. (9) A concave portion can be formed by a simple process of bending a metal roof material processed by general roll forming. (10) Since the recess and the protrusion are fitted, the connecting force, waterproofness, airtightness, etc. are improved. 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), 2 (a), and 2 (b) are explanatory views showing a typical example of a roofing material A made of a metal roofing material B and a backing material C, and FIG. Is an end view of the aa portion of FIG. 2 (a), FIG. 1 (b) is a sectional view of the aa portion of FIG. 2 (a), and FIG. 1 (c) is a sectional view of the bb portion of FIG. FIGS. 3A, 3B, 4A, and 4B are explanatory views showing a construction state of the roof material A. FIG. In the figure, α indicates a base, and β indicates a fixture such as a nail.

  As shown in FIGS. 3 (a), 3 (b), 4 (a) and 4 (b), the base α is composed of a rafter 1, a field plate 2, and a waterproof sheet 3 (indicated by a one-dot chain line). It shows a wooden foundation. 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 roofing material B has a long plate shape. As shown in FIGS. 1A to 1C, the decorative surface 4 having a substantially horizontal surface, the back surface 5, and the tip of the decorative surface 4 are formed. A stepped decorative surface 6 that hangs downward, an upper surface 7 that protrudes inward along the stepped decorative surface 6 and the decorative surface 4, an innermost piece 8 that protrudes downward from the tip of the upper surface 7, and an innermost piece 8. A substantially U-shaped engagement groove 10 is formed from the insertion piece 9 whose tip protrudes underwater, the upper surface 7, the innermost piece 8, and the insertion piece 9, and is inserted by the upper surface 7 and the engagement groove 10. As shown in FIGS. 1 (b), 1 (c), 2 (a), and 2 (b), a gap 11 is formed, and the decorative surface 4 has a protruding piece 4a further protruding from the water-side tip of the decorative surface 4. In addition, the protruding piece 4a on the underside of the decorative surface 4 is bent upward in the drawing to form a recess 4b to form a male connecting portion 12.

  Further, as shown in FIGS. 1A to 1C, a fixed piece in which the upper end portion of the decorative surface 4 protrudes further to the upper water side and the tip hangs down to the lower water side at the upper surface portion of the decorative surface 4. 15, a first waterproof piece 13 with the lower end of the fixed piece 15 bent upward, an upper surface 14 with the tip of the first waterproof piece 13 protruding upward, a top surface 14, and a fixed surface 15. A fitting groove 16 that fits into the insertion piece 9 formed in the above, a fitting piece 17 in which the tip of the upper surface 14 is bent downward, and a tip of the fitting piece 17 that protrudes downward. A female connecting portion 21 is formed from a two waterproof piece 18, a protrusion 19 formed at the tip of the second waterproof piece 18, and a concave groove 20 in which the second waterproof piece 18 is recessed.

  The stepped decorative surface 6 is connected to the second waterproof piece 18 as shown in FIGS. 3A, 3B, 4A, and 4B. That is, the stepped decorative surface 6 collides with the tip end portion of the second waterproof piece 18 during fitting, and the second waterproof piece 18 is deformed by its own springback by the collision force and is firmly connected.

  The first waterproof piece 13 is a part that functions as a part of the fitting piece 17 while adding a waterproof function by bending upward.

  The second waterproof piece 18 prevents rain and wind blown onto the roof material A from directly blowing onto the upper surface 7 of the roof material A, and prevents the roof material A from being peeled off by the wind. That is, as shown in FIG. 4 (b), when the wind blows as shown by the arrow, the second waterproof piece 18 of the lower roof material A causes the wind to push the tip of the waterproof piece 13 as shown by the one-dot chain line arrow A. The force that lifts up so as to rotate to the center works, but conversely, the force that pushes the insertion piece 9 of the upper roof material A as shown by the alternate long and short dash arrow a works to strengthen the engagement force, and the roof material This prevents A from being peeled off by wind.

  Thus, since the opposing force is canceled in the connection part of roofing material A, unless roofing material A is destroyed or the fixture (beta) formed in the fixing piece 15 falls out from the base (alpha), the roofing material A Is not peeled off by the wind.

  The second waterproof piece 18 has a U-shaped groove formed by projecting the tip of the waterproof piece 13 to the underwater side, and wind and rain that is about to enter the groove is rotated in the opposite direction and discharged. And formed to improve waterproofness.

  The protruding piece 4a is a part that forms a concave part 4b by being partially bent and functions as an improvement in design and 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. Moreover, the recessed part 4b can be formed by the simple process of bending the protrusion piece 4a (pressing process etc.) from the metal roofing material B processed by general roll forming.

  As shown in FIG. 4 (b), the recess 4b fits the protrusion 19 of the female connecting portion 21, improves the connecting force, and improves waterproofness, airtightness, and the like.

  For this purpose, the width from the innermost piece 8 to the recess 4b is W, the width from the tip of the insertion piece 9 to the recess 4b is W1, the length of the fitting piece 17 is H, and the protrusion from the tip of the fitting piece 17 is projected. Assuming that the length to the tip of 19 is H1, W> H, W1> H1, and W≈H.

  The backing material 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 (cross-linked foamed polyethylene sheet, etc.), rock wool , Tex (soft fiber board), rubber sheet, resin sheet, etc., or impregnated, contained, mixed, laminated (single layer or multiple layers), sandwich, etc. with a sound insulation material, fireproof material, etc. You can also. In particular, the non-woven fabric is a non-woven fabric in which various fibers are bonded with an adhesive or the like, unlike a conventional method in which warps and wefts are crossed to make a fabric from a fiber. 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 above description is only one example of the roofing material according to the present invention, and the roofing material A can be formed as shown in FIGS. 5 (a) to (c) to FIG.

  More specifically, FIGS. 5 (a) to 5 (c) to 8 (a) to 8 (d) show a roof material A in which the recess 4b is variously deformed.

  FIG. 9 is a roofing material A in which an even number of recesses 4b are formed, and FIGS. 10 (a) to (j) to FIGS. 13 (a) to (g) are explanatory views showing other embodiments of the recesses 4b.
