DETAILED DESCRIPTION OF THE INVENTION
The roof material according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is an explanatory view showing a typical example of a roof material A made of a metal roof material B and a backing material C, and FIGS. 2A and 2B 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.
[0007]
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. 2 (a) and 2 (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.
[0008]
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.
[0009]
More specifically, the metal roofing material B has a long plate shape, and as shown in FIG. 1, a stepped decorative surface in which a substantially horizontal decorative surface 4, a back surface 5, and a tip of the decorative surface 4 are suspended downward. 6, the upper surface 7 projecting inward along the stepped decorative surface 6 and the decorative surface 4, the innermost piece 8 projecting downward from the tip of the upper surface 7, and the distal end of the innermost piece 8 projecting below the water A substantially U-shaped engaging groove 10 is formed from the inserted piece 9, the upper surface 7, the innermost piece 8, and the inserted piece 9, and an insertion gap 11 is formed by the upper surface 7 and the engaging groove 10. The mold connecting portion 12 is used.
[0010]
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 insertion piece formed in a substantially U-shaped cross section from a first waterproof piece 13 having a lower end bent upward, an upper surface 14 projecting the tip of the first waterproof piece 13 from the water side, and an upper surface 14 and a fixed surface 15. 9, a fitting groove 13 that fits into the fitting groove 16, a fitting piece 13 a in which the tip of the upper surface 14 is bent under water, and a second waterproof piece 13 b that projects the tip of the fitting piece 13 a under water and upward. A female connecting part 17 is formed from the above.
[0011]
The stepped decorative surface 6 is connected to the second waterproof piece 13b as shown in FIG. 2 (b). 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.
[0012]
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 to 5 mm). This is a relationship necessary 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.
[0013]
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.
[0014]
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. 3, 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 dashed-dotted arrow a. 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.
[0015]
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.
[0016]
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.
[0017]
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.
[0018]
What has been described above is only one example of the roofing material according to the present invention, and the roofing material A can also be formed as shown in FIGS.
[0019]
【The invention's effect】
As described above, according to the roofing material according to the present invention, (1) waterproofness can be maintained even when the fitting material formed with the first waterproofing piece and the second waterproofing piece drops the roofing 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 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 waterproofing piece cancels the opposing forces in the joints between the roofing materials. Therefore, unless the roofing material is destroyed or the fixture formed on the fixing piece falls off the ground, The material is not peeled off by the wind. There are features and effects.
