2. Description of the Related Art Ordinary house construction involves a process of mounting a foundation on a concrete foundation, placing pillars on the foundation, placing beams, constructing a hut assembly, and finally roofing the roof. become. As described above, since the construction is performed sequentially from the bottom upward, all the construction is performed locally. In the case of a tiled roof, one tile is placed on one
I fix it.

[0003] As described above, the construction method in which conventional tiles are roofed one by one is cumbersome, requires skill, and requires a long construction period. In the completed state, if the tile is weakly fixed, it is blown off by a typhoon, etc., or if the weather is strong,
There is also a problem that rain leaks from gaps between the tiles.

In order to solve such a problem, as described in Japanese Utility Model Application Laid-Open No. 58-118130, a long aluminum molded roof tile having a structure in which a plurality of roof tiles are connected and integrated has been proposed. .

[0005]

However, since the hole is opened and bolts and screws are inserted from the outside and attached to the shed, even if the hole is closed, the leakage will occur completely and permanently due to deterioration over time. It is not always possible to prevent this, and it is necessary to carefully perform jointing, which causes an increase in cost. Since a seam is formed, rain is likely to leak from the seam.

[0006] In addition, since a normal roof tile is retrofitted with a nosed roof tile for raining, the construction work is not only troublesome but also troublesome.
Many damages such as the removal of roof tiles during a typhoon.

Also, as described above, foundation → floor → shaft →
There is a problem that the construction period is long and the construction cost is high because the construction is performed sequentially from bottom to top in the order of hut and roof. If it rains before roofing, the construction work will have to be interrupted and the construction period will be prolonged.
