Description

  The present invention relates to a roofing material that has an unprecedented feeling and workability as a roofing material, and has a waterproof function, a heat insulating function, a dew condensation prevention function, a snow stop 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). Conventionally, metal roofing materials have attracted attention for roofs in terms of vibration resistance, strength, workability, and weight. However, metal roofing materials are poor in design, and compared to roofing materials such as tiled roofs with large irregularities, there is a risk that the snow on the roof can easily fall under the eaves. Roof structures using roof materials with added functions have been developed. (For example, refer to Patent Documents 3 and 4).

  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. However, in the structures of Patent Documents 3 and 4, when the upper roof material is applied to the lower roof material, the upper roof material is bent to apply the roof material. For this reason, there have been disadvantages such as 1) poor workability, 2) difficult construction, 3) rain leakage if construction is not ensured, and 4) damage to the roof material surface.

  In order to solve such drawbacks, the present invention has a waterproof piece protruding upward at the water-side tip of the decorative surface, a water-stopping piece protruding below the water and a water-proof piece protruding above the water piece at the tip of the waterproof piece. A fitting piece is formed, and a vertical piece projecting upward at the tip of the makeup surface below the water, a stepped makeup surface hanging downward at the tip of the makeup surface below the water, and the vicinity of the tip of the makeup surface While forming the innermost piece protruding downward and the insertion piece with the tip of the innermost piece protruding below the water, the water-stopping piece is always in contact with the back surface near the bottom of the makeup surface water when connected The formed roofing material is provided.

  According to the roofing material according to the present invention, 1) Even if the roofing material is dropped into a structure, waterproofness can be maintained by forming a water stop groove. 2) Even if it is used on a steep roof, the connected upper roof material does not fall by its own weight, so it is not necessary to hold it down by hand to prevent the roof material from falling, and construction is easy. It is. 3) A step is formed by forming a stepped decorative surface to add a profound feeling to the roof, and a space is formed inside, so that wind and rain do not directly hit the connecting portion of the roofing material. 4) Since the opposing forces are offset within the joints between the roofing materials due to the formation of waterstops, the roofing material is peeled off by the wind unless the roofing material is destroyed or the fixtures fall off the groundwork. There is no. 5) Since the vertical piece has a snow stop function, there is no worry of rain leakage due to the construction of the snow stop fittings. 6) Since it is a drop-in structure, when snow is piled up on the roof, the connection part is more firmly fitted by the load, so that waterproofness and airtightness are improved. 7) Due to the formation of the projecting piece, there is a snow road at the connecting portion, and there is no rain leakage from the connecting portion due to suga leakage. 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) and 1 (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, FIG. 2 is a sectional view showing a fixture D, FIG. 3 (a), (B) is explanatory drawing which shows the construction state of the roofing material A. FIG. 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 plate 2, and a waterproof sheet 3 (indicated by a one-dot chain line) as shown in FIGS. 3 (a) and 3 (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, an existing roof structure in which an existing roof (not shown) such as a new roof 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, for example, 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.). . 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 is in the form of a long plate, and as shown in FIG. 1 (a), the substantially horizontal surface of the decorative surface 4, the back surface 5, and the tip of the decorative surface 4 on the underwater side. Has a vertical piece 6 projecting upward, a stepped decorative surface 6a projecting downward, an upper surface 7 projecting inward along the stepped decorative surface 6a and the decorative surface 4, and a tip of the upper piece 7 projecting downward A substantially U-shaped engagement 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 piece 7, the innermost piece 8, and the insertion piece 9. The insertion gap 11 is formed between the stepped decorative surface 6 and the insertion piece 9 to form a male connecting portion 12.

  Further, as shown in FIG. 1 (a), a waterproof piece 13 formed by bending the tip of the decorative surface 4 upward at the water-side end of the decorative surface 4, and the tip of the waterproof piece 13 facing downward. A female connecting portion 17 is formed from a protruding water-stopping piece 14, a water-stop groove 15 formed by the water-stopping piece 14, and a waterproof protrusion 16 in which the tip of the water-stopping piece 14 is bent in a goby shape.

  The vertical piece 6 forms a snow stop function and a snow cavity in the connecting portion to prevent rain leakage from the connecting portion due to suga leakage.

  The stepped decorative surface 6a forms a step to give a profound feeling to the roof, forms an insertion gap 11 inside, and prevents the wind and rain from directly hitting the connecting portion of the roofing material A. By forming the gap between the connecting portions formed at the time of connection with each other, for example, the tip portion of the stepped decorative surface 6a and the tip portion of the water blocking piece 14 above and below, the waterproofness is improved. Is. Further, the stepped decorative surface 6a is connected to the waterproof protrusion 16 as shown in FIG. That is, the stepped decorative surface 6a collides with the tip end portion of the waterproof protrusion 16 at the time of fitting, and the waterproof protrusion 16 is deformed by its own springback by the collision force and is firmly connected.

  The insertion gap 11 is inserted into the engagement groove 10 so that the stepped decorative surface 6 does not get in the way when the roof material A is connected as shown in FIG. It is formed so that it can be done.

  More specifically, as shown in FIG. 1B, when the width of the insertion gap 11 is H and the width from the tip of the locking piece 19 to the tip of the waterproof protrusion 16 is h, H≈h and H> h ( H ≧ h).

  Due to this relationship, the waterproof protrusion 16 is fitted in the insertion gap 11.

  The water stop piece 14 is formed to improve the waterproof property by forming a water stop groove 15 having a U-shaped cross section by projecting the tip of the waterproof piece 13 to the water side.

  As shown in FIG. 3 (b), the water-stopping piece 14 and the waterproof protrusion 16 are formed in a state in which they are in contact with the upper piece 7 by the springback when the roofing materials A are connected to each other. A state of good confidentiality will continue.
