Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a vertical thatched roof structure applied to finish a roof surface of a building smooth.

[0002]

2. Description of the Related Art In recent years, the roof of a building has been diversified in appearance by placing emphasis on design, and under such circumstances, the roof shape is spherical. There is a demand for a roof material having a smooth roof surface even for a roof having a special shape including a two-dimensional or three-dimensional curved surface such as a cone.

Conventionally, in this type of vertical roof structure, for example, Japanese Patent Application No. 4-3108 previously proposed by the present applicant.
There is one having a configuration disclosed in No. 31 or the like.

[0004]

However, in the above-described conventional vertical thatched roof structure, the side edge portions of the face plate portions of the left and right adjacent thatched roof panels are bent downward to form the engaging portions, Since this engaging portion is to be held by the suspension member fixed on the base member laid on the roof through the holding member, when the roof plate is bent,
The engaging portions formed at the side edge portions of the face plate portion have high gobs, which is an obstacle and is very difficult to process.

Even if such a roof plate can be bent, the shape of the engaging portion tends to be uneven,
As a result, when the roof shape is a spherical surface or the like, the fitting state of the roof plates is deteriorated, which causes problems in design and structure.

Further, in order to facilitate the bending of the roof plate, it is conceivable to lower the height of the engaging portion and to form the shape of the engaging portion into a simple flat roof type, but the roof surface is loose. On the slope, there was a problem that rainwater, etc. would infiltrate from such a seam joint, resulting in poor rain finish.

[0007]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a vertically-roofed roof structure capable of finishing a roof surface in a smooth and rainy manner even if the roof shape is a special shape such as a spherical surface. It is in.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a gutter member along the direction of inclination of a base, and a lower suspension member is laid across the gutter member. The roof surface is smoothed by fixing it on the base member and connecting and fixing the side edge portions of the face plate portions of the vertically-roofed roof plates adjacent to each other on the lower suspension member to each other. A vertically-roofed roof structure, in which one side edge portion of the face plate portion of the vertically-roofed roof plate has an engaging portion formed by folding back on the back side, and the other side edge portion. Has a portion to be polymerized that is formed by extending outward through a step portion that is inclined downward, and to the portion to be polymerized on the other side edge portion, the engaging portion of the one side edge portion. The facet portion of the vertical roofing roof plate is superposed so as to be flush with the surface of the roof.

[0009]

That is, according to the present invention, by adopting the above-mentioned configuration, the engaging portion of one side edge portion of the face plate portion of the vertical thatched roof plate is formed by folding it back to the back side, and The side edge portion is formed on the overlapped portion by extending outward through a step portion inclined downward, and the overlapped portion of the other side edge portion is engaged with the engagement portion of one side edge portion. Since the face plate portion of the vertically roofing roof plate is superposed flush with each other, the shapes of the engaging portion and the overlapped portion of the side plate portions of the vertically roofing roof plate are simple, and the goby height is high. It is low, so that the roof plate can be easily bent, and a large error does not occur in the engaging portion, so that the fitting state can be accurately performed.
It is possible to easily adapt to a roof shape having a three-dimensional or three-dimensional curved surface.

Further, since the gutter member is arranged below the engaging portion of the roof plate, even if rainwater enters from the engaging portion, the rainwater can be received by the gutter member. Ingress of rainwater is prevented, which improves rain performance.

Further, the overlapped portion of the roof plate extends outward through a step portion which is inclined downward, and the overlapped portion is formed at a position lower than the face plate portion, and the engaging portion with respect to the face plate portion. Since the surfaces are connected so as to be flush with each other, the roof surface becomes smooth and the design is improved.
