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, 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 provides a waterproof piece protruding upward at the water-side tip of the decorative surface, a water-stopping piece protruding from the water-proof tip, and a water-stopping tip. The lower piece is folded back to the water side, and the top of the lower piece is folded back to the water side to form the upper piece that protrudes below the waterproof piece. Forms a stepped decorative surface, an innermost piece that projects downward near the tip of the decorative surface, and an insertion piece that projects the tip of the innermost piece to the underwater side. The roof material formed so that the front-end | tip of a water stop piece may be fitted in the state which contacted the near back surface and the level | step difference decorative surface inside is provided.

  According to the roofing material according to the present invention, 1) Even if the roofing material is dropped, the waterproof property can be maintained by forming the 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 out of 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 part, and there is no rain leakage from the connecting part due to suga leakage. There are features and effects.
