Description

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

  In general, many roof materials obtained by processing metal plate materials by roll molding, press molding, and the like have been put on the market, and the shape thereof is a so-called hook structure. (For example, refer to Patent Documents 1 and 2).

JP 2002-038658 A JP 2002-155602 A

  However, 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. 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 drawbacks, the present invention provides a substantially horizontal decorative surface, an upper surface that projects the water-side tip of the decorative surface back along the decorative surface, and protrudes toward the water side, and the middle of the upper surface is on the indoor side. It is abbreviated from a stepped decorative surface that hangs down, an innermost piece that projects the tip of the upper surface to the indoor side, an insertion piece that projects the tip of the innermost piece to the water side, and an upper surface, the innermost piece, and the insertion piece. A male connection part that forms a U-shaped engagement groove, an insertion gap is formed by the upper surface and the engagement groove, and a water-side end part of the decorative surface further protrudes the upper end part of the decorative surface to the water side, A cross section from a fixed piece with the tip hanging down to the water side, a first waterproof piece with the lower end of the fixed piece bent to the outdoor side, an upper surface protruding the tip of the first waterproof piece to the water side, and the upper surface and the fixed surface A fitting groove for fitting with the insertion piece formed in a substantially U shape, a fitting piece with the top end bent to the water side, and the tip of the fitting piece on the water side One and a second waterproof member that protrudes to the weather side to form a female connection portion, and the width between the water bottom water top and second waterproof piece fitting pieces, the width between the innermost piece and the stepped decorative surface Is provided with a roofing material having a substantially the same length.

  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. 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 is an explanatory view showing a typical example of a roofing material A made of a metal roofing material B and a backing material C, and FIGS. 2A and 2B to 4 are explanatory views showing a construction state of the roofing material A. FIG. is there. In the figure, α indicates a base, and β indicates a fixture such as a nail.

  The base α indicates a wooden base composed of a rafter 1, a field board 2, and a waterproof sheet 3 (shown by a one-dot chain line) as shown in FIGS. 2 (a) and 2 (b) to FIG. is there. 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.

More specifically, the metal roofing material B has a long plate shape. As shown in FIG. 1, the decorative surface 4 having a substantially horizontal plane, the back surface 5, and the underwater front end of the decorative surface 4 are applied to the decorative surface 4. The upper surface 7 that protrudes to the upper side of the water, the stepped decorative surface 6 that hangs down the middle of the upper surface 7 toward the indoor side , the innermost piece 8 that protrudes the tip of the upper surface 7 toward the indoor side , and the distal end of the innermost piece 8 A substantially U-shaped engagement groove 10 is formed from the insertion piece 9 projecting to the water side, the upper surface 7, the innermost piece 8 and the insertion piece 9, and the insertion gap is formed by the upper surface 7 and the engagement groove 10. 11 is formed as a male connecting portion 12.

Further, as shown in FIG. 1, the water-side end portion of the decorative surface 4 includes a fixed piece 15 that protrudes further from the upper end portion of the decorative surface 4 to the water-side and the tip hangs down to the water-side. The said insertion formed in the cross-sectional substantially U-shape from the 1st waterproof piece 13 which bent the lower end to the outdoor side , the upper surface 14 which protruded the front-end | tip of the 1st waterproof piece 13 to the water upper side, and the upper surface 14 and the fixed surface 15 The fitting groove 16 fitted to the piece 9, the fitting piece 13a in which the tip of the upper surface 14 is bent under water, and the tip of the fitting piece 13a protrudes on the water side and outdoors. A female connecting portion 17 is formed from the piece 13b.

  The stepped decorative surface 6 is connected to the second waterproof piece 13b as shown in FIG. That is, the stepped decorative surface 6 collides with the tip of the second waterproof piece 13b during fitting, and the second waterproof piece 13b is deformed by its own springback by the collision force and is firmly connected.

  Assuming that the width T between the water upper end of the fitting piece 13a and the water lower end of the second waterproof piece 13b and the width between the innermost piece 8 and the stepped decorative surface 6 are t, T <t and T≈t (approximately equal). Therefore, they are formed to have substantially the same length. Actually, it is about t = T + (0.5 to 5 mm). This is a necessary relationship for the second waterproof piece 13b to be deformed by its own springback due to its collision force and to be firmly connected to the inside of the stepped decorative surface 6.

  The 1st waterproof piece 13 is a part which functions also as a part of fitting piece 13a while adding a waterproof function by bending upward.

  The second waterproof piece 13b prevents rain and wind blowing on 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, when the wind blows as shown by the arrow, the second waterproof piece 13b of the lower roofing material A rotates around the tip of the waterproof piece 13 as shown by the one-dot chain line arrow A by the wind. However, the upper surface 14 is pressed against the insertion piece 9 of the upper roof material A as shown by the alternate long and short dash line a, and the engagement force is strengthened. Is to prevent peeling.

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

  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.

What has been described above is only one embodiment of the roofing material according to the present invention, and the roofing material A may be formed as shown in FIGS. 5 (a) and (b) to FIGS. 8 (a) and (b). it can.

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