Detailed Description of the Invention 【Technical field】

 TECHNICAL FIELD The present invention relates to a roofing material to be installed on a steep roof.

[Background Art] Conventionally, a plurality of roof panels have been laid in the direction of the eaves and purlins, and the roof is tiled to form a roof. However, in the case of a steep roof, the roof panel is Not only was it difficult to install, it was also dangerous, and it was difficult to secure the waterproofness of the joints between the roof panels, to illuminate, and to provide a ventilation function.

[Object of the invention]

The present invention has been made in view of the above circumstances, and an object thereof is to provide a roof material that can be easily roofed on a steep roof, has excellent workability, and is also easy to secure waterproofness. It is to improve the roofing workability.

DISCLOSURE OF THE INVENTION

The roofing material of the present invention is one side located along the eaves direction of the front panel 2 of the roof panel A formed by stretching the surface plate 2 on the frame 1 and extending over substantially the entire length in the eaves direction. The end portion is recessed downward to form a step portion 3, and a roof tile A having a width substantially equal to the length of the roof panel A in the purlin direction is provided on the roof panel A at one side thereof.
The other side is made to project from the other side end portion of the roof panel A by being positioned in the approximate center, and a plurality of sheets are attached in the eaves direction, and the above-mentioned object is achieved by this configuration. That is, at the time of roofing construction, a plurality of roofing materials R are attached along the direction of the purlin 6 so that the roofing can be easily performed, and the roof panel A above the stepped portion 3 is located outside of one side of the roof tile. Is formed as a mounting recess 3a, and the other side of the roof tile 5 is formed as a cover piece 5a to be fitted into the mounting recess 3a of another roof panel A. Therefore, the cover piece 5a of the roof tile 5 is mounted on the adjacent roof panel A. By arranging the roof panels A in parallel with each other, it is possible to prevent rainwater from directly falling between the ends of the roof panels A by covering the space between the ends of the adjacent roof panels A with the covering piece 5a. The waterproofness between the end portions of the roof panel A can be enhanced, and furthermore, by disposing the draining material 4 on the step portion 3 of the surface plate 2 of the roof panel A, the roof tiles 5 are joined by the draining material 4. The waterproof property of the part B can be ensured. Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. The roof panel A is composed of a frame 1 and a surface plate 2 which is a plywood. In this embodiment, the frame body 1 is composed of a main body 1a assembled in a lattice shape and an auxiliary material 1b arranged along the longitudinal direction of the main body 1a, and the height of the auxiliary material 1b is lower than that of the main body 1a. In addition, by making the thickness of the auxiliary plate 2b stretched on the auxiliary member 1b smaller than the thickness of the surface plate body 2a stretched on the main body 1a, one side end portion along the longitudinal direction of the surface plate 2 is formed. A step portion 3 is formed. The length of the roof panel A in the longitudinal direction is substantially equal to the length of the roof to be installed and installed in the eaves direction, and the lateral direction thereof is approximately equal to the width of the roof tile 5. In this roof panel, a plurality of roof tiles 5 such as slate plates are positioned such that one side in the purlin direction is located up to approximately the center of the stepped portion 3 and the other side is projected from the other end portion of the roof panel A. A roof material R is formed by attaching the roof panel A along the eaves direction. At the time of this construction, as shown in FIG. 6, a plurality of roof materials R are attached to the timber 7 in sequence by joining the roof tiles 5 to each other on the step 3 along the direction of the purlin 6. In this case, a draining member 4 is arranged on the step portion 3 of the roof panel A, and as shown in FIG. 7, the draining member 4 ensures the waterproof property of the joint B between the roof tiles 5.

【The invention's effect】

In the present invention, the one side end of the surface plate of the roof panel, which is formed by stretching the surface plate on the frame body and extends over substantially the entire length in the direction of the eaves, is located downward. To form a stepped portion on the roof panel, and by placing one side of the roof tile with a width approximately equal to the length of the roof panel in the purlin direction on one side at the approximate center of the stepped portion, the other side Since multiple pieces are installed projecting from the side edge in the direction of the eaves, at the time of roofing construction, by installing multiple roofing materials along the purlin direction, the roof tiles can be abutted and easily roofed. ,
Moreover, since the upper side of the step of the roof panel is formed as a mounting recess on the outside of one side of the roof tile, and the other side of the roof tile is formed as a cover piece that is fitted into the mounting recess of another roof panel, the cover piece of the roof tile is By installing the roof panels side by side by fitting them into the mounting recesses of the adjacent roof panels, cover the space between the edges of the adjacent roof panels with a cover piece to prevent rainwater from directly falling between the edges of the roof panels. It is possible to improve the waterproofness between the edges of the roof panel, and by arranging the draining material on the step of the surface panel of the roof panel, the waterproofness of the joint portion of the roof tiles can be improved by this draining material. Can be secured.
