TECHNICAL FIELD OF THE INVENTION
The present invention relates to a roofing material having an unprecedented solid feeling and workability as a roofing material, and having a waterproof function, a heat insulating function, a dew condensation preventing function, a snow stopper function, and the like.
[0002]
[Prior art]
2. Description of the Related Art In general, many roof materials obtained by processing a metal plate material by roll forming, press forming, or the like have been put on the market, and the shape has been a so-called hook structure. (For example, see Patent Documents 1 and 2). Conventionally, metal roofing materials have been receiving attention due to the relationship between vibration resistance, strength, workability, and weight. However, metal roofing materials are poor in design, and there is a risk that snow on the roof will fall easily under the eaves compared to roofing materials such as tiled roofs with large irregularities. Roof structures using roof materials with added functions have been developed. (For example, see Patent Documents 3 and 4).

[Problems to be solved by the invention]
However, since Patent Literatures 1 and 2 have a hooking structure, when used on a steeply sloping roof, the connected upper roof material falls by its own weight, so the fixing part of the upper roof material is fixed by a fixture. Until it was fixed with nails, it was necessary to hold down the roofing material by hand so that it would not fall off, and the construction was difficult. However, in the structures of Patent Literatures 3 and 4, when the upper roof material is applied to the lower roof material, the upper roof material is subjected to a bending process and the roof material is applied. For this reason, (1) poor workability, (2) difficult to construct, (3) causes rain leak if the construction is not secured, and (4) damages to the surface of the roofing material. there were.
[0005]
[Means for Solving the Problems]
In order to solve such a drawback, the present invention has a first waterproof piece having a water-side end of a decorative surface projecting upward, a fitting piece having a first waterproof piece having a tip projecting upward, A second waterproofing piece with the tip of the waterproofing piece projecting downwards, and a fixed piece with the tip of the decorative face projecting upwards above the water surface, and a vertically projecting vertical tip at the underwatering tip of the decorative face. Piece, a stepped decorative surface protruding downward, an innermost piece protruding downward near the underwater end of the decorative surface, an insertion piece protruding downward at the tip of the innermost piece, and a decorative surface And the innermost piece and the insertion piece form an engagement groove, and the width between the water upper end of the fitting piece and the water lower end of the second waterproofing piece is substantially the same as the width between the innermost piece and the stepped decorative surface. It is intended to provide a roof material formed in a length.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the roofing material according to the present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory view showing a typical example of a roofing material A composed of a metal roofing material B and a backing material C. FIGS. 2A and 2B are explanatory views showing a construction state of the roofing material A. In the drawing, α indicates a base and β indicates a fixture such as a nail.
[0007]
The foundation α indicates a wooden foundation composed of a rafter 1, a ground board 2, and a waterproof sheet 3 (indicated by a dashed line) as shown in FIGS. 2A and 2B when newly constructed. That is, it is a groundwork α of a general structure in which the baseboard 2 is laid on the rafter 1 and the waterproof sheet 3 is provided on the baseboard 2. In addition, H-shaped steel, I-shaped steel, grooved steel, lightweight grooved steel, lip channel steel, equilateral angle steel, unequal angle angle steel, square steel (square pipe), circular steel (circular pipe), It is also possible to use a steel base material using such as. Of course, when the existing roof is to be repaired 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 ground α becomes the ground α. Of course, the base α without forming the waterproof sheet 3 may be used.
[0008]
The metal roofing material B is, for example, a metal plate (a color steel plate, a copper plate, an aluminum plate, a titanium plate, a stainless steel plate, a sandwich steel plate, a clad steel plate, or the like) formed by roll forming, press forming, extrusion forming, or the like. . Of course, instead of the metal roofing material B, the roofing material A may be formed of a ceramic material, a synthetic resin material (plastic), or the like instead of the metal roofing material B.
[0009]
More specifically, the metal roofing material B is in the shape of a long plate, and as shown in FIG. 1, the decorative surface 4, the back surface 5, and the lower end of the decorative surface projecting upward substantially in a horizontal plane. A vertical piece 6, a stepped decorative surface 6 a protruding downward, an upper surface 7 protruding inward along the step decorative surface 6 a and the decorative surface 4, and an innermost piece 8 protruding downward at a tip of the upper surface 7. A substantially U-shaped engagement groove 10 is formed from the insertion piece 9 having the tip of the innermost piece 8 protruding downward, and the upper surface 7, the innermost piece 8 and the insertion piece 9. An insertion gap 11 is formed by the engaging groove 10 to form a male connecting portion 12.
[0010]
Also, as shown in FIG. 1, the upper end of the decorative surface 4 is further protruded to the upper water side and the fixing piece 15 having the tip hanging downward is formed at the water-side end of the decorative surface 4. A first waterproof piece 13 having a lower end bent upward, an upper surface 14 having a tip of the first waterproof piece 13 protruding above the water, and an insertion piece formed in a substantially U-shaped cross section from the upper surface 14 and the fixing surface 15 9, a fitting piece 13 a with the tip of the upper surface 14 bent downward, and a second waterproof piece 13 b with the tip of the fitting piece 13 a projecting downward and upward. Thus, the female connecting portion 17 is formed.
[0011]
The vertical piece 6 has a snow stopper function and forms a hollow due to snow at the connecting portion, thereby preventing rain from leaking from the connecting portion due to suga leakage.
[0012]
The step makeup surface 6a is connected to the second waterproof piece 13b as shown in FIG. That is, at the time of fitting, the stepped decorative surface 6a collides with the distal end portion of the second waterproof piece 13b, and the second waterproof piece 13b is deformed by its own springback due to the collision force, and is firmly connected.
[0013]
Assuming that the width T between the water upper end of the fitting piece 13a and the water lower end of the second waterproofing piece 13b and the width between the innermost piece 8 and the step decorative surface 6a are t, T <t and T ≒ t (substantially 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 waterproofing 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 6a.
[0014]
The first waterproof piece 13 is a part that bends upward to add a waterproof function and also functions as a part of the fitting piece 13a.
[0015]
The second waterproofing piece 13b prevents rain and wind blowing on the roofing material A from directly blowing on the upper surface 7 of the roofing material A, and prevents the roofing 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 by the wind. On the other hand, as shown by the dashed-dotted arrow a, the upper surface 14 acts to hold down the insertion piece 9 of the roof material A at the upper stage, and the engagement force is strengthened, and the roof material A winds. To prevent peeling.
[0016]
As described above, since the opposing forces are canceled in the connection portion between the roofing materials A, the roofing material A is not destroyed unless the roofing material A is broken or the fixing tool β formed on the fixing piece 15 falls off from the base α. Are not peeled off by the wind.
[0017]
The second waterproofing piece 13b forms a groove having a U-shaped cross section by projecting the tip of the waterproofing piece 13 to the underwater side, and the wind and rain entering by the groove are rotated in the opposite direction to be discharged. It is formed to improve waterproofness.
[0018]
The backing material C functions as a waterproofing material, a heat insulating material, a sound absorbing material, a cushioning material, a fireproofing material, a dew condensation preventing material, and the like, and includes a nonwoven fabric, a synthetic resin foam sheet (a crosslinked foamed polyethylene sheet, etc.), rock wool. , Tex (soft fiber board), rubber sheet, resin sheet, etc., or impregnated, contained, mixed, laminated (one or more layers), sandwiched, etc., with sound insulating material, refractory 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 the conventional method in which warp and weft cross each other to convert a fiber into a fabric. In this nonwoven fabric, the fibers intersect in parallel first, 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 under heat and pressure and bonding with each other. Of course, if the material itself does not have a waterproof property, the material is coated with a resin material, or a waterproof function is added to one or both surfaces with a water repellent, a waterproof coating agent, or the like.
[0019]
The 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. 4 (a), (b) to 6 (a), (b). it can.
[0020]
【The invention's effect】
As described above, according to the roofing material of the present invention, (1) formation of the first waterproofing piece and the second waterproofing piece can maintain waterproofness even when the roofing material is dropped. (2) Due to the drop-in structure, even when used on a steeply sloping roof, the connected upper roof material does not fall by its own weight, and hold it by hand so that it does not fall until it is fixed The construction is easy because there is no need to install. {Circle around (3)} Since the upper end of the water on the decorative surface and the fixing piece are formed at the same level, the step may be small and there is no deformation due to the load on 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 comes into contact with the upper surface of the upper roof material, and the second waterproof piece always springs in the engagement groove. It exerts a back effect and improves waterproofness and airtightness. (5) The formation of the second waterproofing piece cancels out the opposing forces in the connection between the roofing materials (the force that tries to peel off the lower roofing material due to the wind becomes the force that tries to hold down the upper roofing material. ), The roofing material is not peeled off by the wind unless the roofing material is broken or the fixing tool formed on the fixing piece falls off the base. (6) Since the vertical piece has the function of snow stopper, there is no need to worry about rain leakage due to the construction of the snow stopper. (7) Since the structure is a drop-in structure, when snow is piled on the roof, the connection portion is further firmly fitted by the load, thereby improving waterproofness and airtightness. {Circle around (8)} Due to the formation of the projecting piece, a snowy road is formed at the connecting portion, and there is no rain leak from the connecting portion due to suga leakage. There are features and effects.
