Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a roof tile having high wind resistance.

[0002]

2. Description of the Related Art When a roof tile used for a building structure such as a house is attached to a sloping roof plate, for example, a plurality of horizontal bars or crossbars are provided in parallel to the roof plate and the roof tile butt is arranged. A dry method is used in which a hooking protrusion protruding from the back surface of the part is positioned by hooking it on the crosspiece or crossbar, and the bottom portion is fixed to the crosspiece or crossbar or field board with a nail. However, even the roof tiles fixed by such a dry construction method are still insufficient in wind resistance, and it has not been possible to sufficiently prevent the tiles from being damaged by a large typhoon or strong wind. Is the reality.

[0003]

On the other hand, in a so-called zigzag flat tile which is arranged with a shift of a half pitch in the lateral direction, another flat edge which is one side edge of the tile is laterally adjacent. The tabs or nails for hooking locally thinly hooked parts provided on the head (downstream side edge of the slope) of the collar that is inserted under the roof tile are the head of the flat tile. Projected at the center of the bottom (the upstream edge of the slope) of another flat tile to be inserted under the section so that the height is the same as the thickness of the collar, and the tabs above the bottom. It has been proposed that the wind resistance of the flat tiles is improved by preventing the flat tiles from being turned up. However, since such a flat tile is fixed by a nail for stopping its hip and a claw for hooking a hooked portion provided on the head side of the collar, the collar and the head are fixed. Wind resistance from the corners between the head and the head is certainly enhanced, but from the corner between the head and the head that overlaps the collar of other laterally adjacent flat tiles. There was the inconvenience that it was not possible to obtain that much wind resistance against turning over. This is because the wind resistance of the flat tiles on the roof needs to be improved for winds in various directions.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a roof tile having sufficient wind resistance.
