EFFECTS OF THE INVENTION The metal roofing material of the present invention has a plurality of convex linear bodies formed in parallel with each other in the left-right direction at appropriate intervals by a thin metal plate, and another roof having the same roof before and after the convex linear body. In a metal roofing material in which a connecting portion with a member is formed, and which can be connected by the convex linear body at each end and the connecting portion to form a metal roof structure, the plurality of convex linear bodies have a large cross-sectional area. The metal roof structure of the present invention is configured by alternately arranging a small one and a small one, and forming the metal roof structure by connecting the convex linear body, the connecting path, and the fitting body. , The end with the connecting path is alone and directly, and the end of the fitting part leaves a space with other metal roofing materials underneath,
Each of them is fixed to the roof base with screws, and similarly, the convex linear bodies and the connecting paths attract air under the flat portion between the convex linear bodies, while flowing air from the lower side to the upper side and outflowing from the upper end of the roof structure. Since the anti-air flow system was constructed, in the metal roofing material, by arranging convex linear bodies having a large cross-sectional area and convex linear bodies having a small cross-section alternately at appropriate intervals, the weight is dispersed and the convex linear body is distributed. It is possible to prevent trampling of the body. In this case, if the convex linear body has a mountain-shaped cross-sectional shape with corners, the rigidity becomes higher, which is more effective.

Further, in the metal roof structure of the present invention, in particular, by fixing the end of the fitting portion of the convex linear body together with other metal roof materials below by leaving a space, it is fixed to the roof base with screws. In addition to the weight described above, a metal roof structure that can sufficiently withstand the peeling action of the metal roof material due to strong wind can be obtained.

Further, in the metal roof structure of the present invention, the convex straight members and the connecting paths attract the air under the flat portion between the respective convex straight members, while flowing air from the lower part to the upper part and flowing out from the upper end of the roof structure. By constructing an anti-air flow system, it is possible to remove moisture from the roof underlay and to prevent the temperature of the attic from rising, especially in summer.

Further, in the case where the cross-sectional shape of the connecting passage is such that the draining projection is formed at the portion which comes into contact with the inside of the fitting body, it is possible to completely prevent rainwater from entering due to strong wind and rain in the front-rear direction. .

In addition, in the case where the convex linear body has a mountain shape with a corner as a cross-sectional shape, the plurality of corners can prevent the rainwater from invading in the left-right direction at the time of a strong wind.

If the end of the connecting portion on the side forming the communication path is bent upward, it is possible to prevent damage during construction of the metal roofing material or transportation of the metal roofing material.
