Description

TECHNICAL FIELD The present invention relates to a roof structure of a building.

(Prior Art) Nowadays, with emphasis on shortening the construction period, there are some buildings with folded roofs in which peaks and valleys extend alternately. As such a roof structure of a building, for example, there is one described in JP-A-62-280447.

In this conventional structure, a parapet is provided in front of the folding plate to cover the tip of the folding plate, a rain gutter is provided between the parapet and the tip of the folding plate, and the tip of the folding plate is provided. An apron is inserted into each trough of the folded plate to provide a face door plate, and a roof cover is provided to substantially entirely cover the gap between the face door plate and the parapet.

(Problems to be Solved by the Invention) However, in such a conventional roof structure of a building, although a leaf door and a roof cover can prevent fallen leaves and the like from falling around a rain gutter, All fallen leaves on the board and roof cover are caught by the apron of the doorboard and accumulated in the valleys of the folded plate, so drainage of rainwater is hindered by the fallen leaves, etc., and the appearance of the building is impaired. There was a problem that

The roof structure of the building of the present invention focuses on the above-mentioned conventional problems, and aims to prevent rainwater drainage from being obstructed by fallen leaves and the like, and also not to impair the aesthetics of the building.

(Means for Solving the Problems) The present invention has been made for the purpose of solving the above problems, and in order to achieve this object, the roof structure of the building of the present invention has a mountain portion and a valley. And a parapet is provided in front of the folding plate to cover the tip of the folding plate, and a rain gutter is provided between the parapet and the tip of the folding plate. In the roof structure of the building, a reinforcing member is provided on the mountain portion of the folded plate so as to cover each valley of the folded plate, and a gap between the tip of the reinforcing member and the parapet is provided. A roof cover is provided so as to cover almost entirely, the upper surface of the reinforcing member and the upper surface of the roof cover are formed to be substantially flat, and both are substantially flat and continuous.

(Operation) In the roof structure of the building of the present invention, the reinforcing material is provided on the mountain portion of the folded plate so as to cover each valley portion of the folded plate, and between the tip portion of the reinforcing material and the parapet. Since the roof cover is provided so as to cover the gap almost entirely, it is possible to prevent fallen leaves and the like from falling into the valley portion of the folded plate or around the rain gutter.

Moreover, since the upper surface of the reinforcing material and the upper surface of the roof cover are formed to be substantially flat and both are substantially flat and continuous, the fallen leaves and the like dropped on these upper surfaces are blown away by wind or rain.
