DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof structure, and more particularly to a roof structure of a horizontal roof using a folded-plate roof material.

[0002]

2. Description of the Related Art As a method of roofing with a folded plate such as a steel plate or an aluminum plate, a vertical roofing method and a horizontal roofing method are generally known.

In the vertical roofing method, folded roof materials are bent in such a manner that the center in the width direction (horizontal direction of the roof surface) is a valley and both ends are ridges, and the roof material is successively arranged along the horizontal direction of the roof surface. A method of laying the roof without nailing, bolting, etc., by arranging and connecting the side ends of the folded shingle roofing material via a hook.

On the other hand, according to the horizontal roofing method, a folded plate roofing material having connection bent portions formed at a ridge side end and an eaves side end is arranged in a character shape on a roof structure, and the roof surface is inclined in a slope direction. The adjacent folded sheet roofing material is suspended by fitting the bent part at the ridge side end of one piece of folded sheet roofing material to the bent part at the eaves side end of the other folded sheet roofing material and connecting it. It is a method of roofing without using a child. In this horizontal roofing method,
In many cases, the joints (horizontal joints) of folded-plate roofing materials that are installed in the horizontal direction of the roof surface are simply made by overlapping the side edges of the folded-sheets. Is set to, for example, about 50 mm.

[0005]

By the way, according to the roof by the horizontal roofing method as described above, there is usually no problem. However, when the wind and rain are severe, for example, when a large typhoon approaches, the roof of the folded plate roof material is not used. Rainwater infiltrates the overlapping part in the direction,
Rarely, rain leaks into the room.

The present invention has been made in view of such circumstances, and has a roof structure capable of reliably preventing rain from leaking from a horizontal joint of a folded-plate roof material in a roof of a roofing method. For the purpose of providing.
