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, 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 compared to the tile roof. (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 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 down, 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 in L shape, formed a protrusion piece, bent the protrusion piece partially, and formed the uneven | corrugated | grooved part is provided.

According to the roof material which concerns on this invention, (1) Waterproofness can be maintained even if the fitting piece which formed the 1st waterproof piece and the 2nd waterproof piece dropped down the roof material. (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 offsets the opposing forces within the connecting portion of the roofing material, so that the roofing material is not destroyed or the fixture formed on the fixing piece does not fall out of the ground. The material is not peeled off by the wind. (6) The uneven | corrugated | grooved part formed in the protrusion piece protruded in L shape exhibits the appearance which has not existed so far, and can form a heavy roof. (7) Since the concavo-convex part has a function of preventing snow, there is no risk of rain leakage due to the construction of the snow stopper. (8) There is no difficult snow stop construction. Or less. (9) An uneven portion can be formed on a metal roof material processed by general roll forming by simple processing such as subsequent press processing. 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, a ceramic material, a synthetic resin material (plastic), or the like may be used.

To further illustrate, the metal roofing B is a long plate shape, as shown in FIG. 1 (a) ~ (c) , and Ryakutaira planar decorative surface 4, a back surface 5, the water of the decorative surface 4 A stepped decorative surface 6 having a lower end projecting in an L shape on the water side , an upper surface 7 rimmed inward along the stepped decorative surface 6 and the decorative surface 4, and a tip of the upper surface 7 protruded to the rear surface side . A substantially U-shaped engaging groove 10 is formed from the innermost piece 8, the insertion piece 9 with the tip of the innermost piece 8 protruding downward, and the upper surface 7, the innermost piece 8, and the insertion piece 9. Then, an insertion gap 11 is formed by the upper surface 7 and the engagement groove 10, and the stepped decorative surface 6 has a protruding piece 4a, as shown in FIGS. 1 (b), 1 (c), 2 (a) and 2 (b). Thus, the protrusion piece 4a on the underwater side of the decorative surface 4 is bent to the surface side in the drawing to form the concavo-convex portion 4b to form the male connecting portion 12.

Further, as shown in FIG. 1 (a) ~ (c) , of粧面4 Water upper portion further projecting water side, a fixing piece 15 of the tip were suspended in water under side, the lower end of the fixing piece 15 The insertion piece 9 formed in a substantially U-shaped cross section from the first waterproof piece 13 bent to the front surface side, the upper surface 14 projecting the tip of the first waterproof piece 13 to the water side, and the upper surface 14 and the fixing surface 15. A fitting groove 16 that fits, a fitting piece 17 whose tip of the upper surface 14 is bent under water, a second waterproof piece 18 that projects the tip of the fitting piece 17 under water, and a second A female connecting portion 21 is formed from a protrusion 19 formed at the tip of the waterproof piece 18 and a recess 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. 4 (a) and 4 (b). 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 roofing material A causes the tip of the waterproof piece 13 to be pushed by the wind as shown by the dashed-dotted 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 protrudes downward from the first waterproof piece 13 to form a space γ having a U-shaped cross section, and this space γ allows wind and rain to enter the interior in the reverse direction. It is formed to improve waterproofness by rotating and discharging.

  The projecting piece 4a is a part that forms a concavo-convex part 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. Moreover, the uneven | corrugated | grooved part 4b can be formed by the simple process of bending the protrusion piece 4a (pressing process etc.) the metal roofing material B processed by the general roll forming.

  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 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 thin felts arranged randomly are 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 5 (c) to FIG.

  More specifically, FIGS. 5 (a) to (c) to FIGS. 7 (a) to (c) show a roof material A obtained by variously deforming the uneven portion 4b.

  In particular, FIGS. 6A and 7C show a roof material A in which an even number of uneven portions 4b are formed.

  FIG. 8 is a construction state sectional view showing the case where the roof material A is used as a wall material.

  Since the roofing material according to the present invention can be used as a wall material as an exterior material, the range of use is wide.
