), and the fitting portion (7b), which has a substantially semicircular cross section, provided at the bottom of both side plates (7a) of this cover (7) is connected to both roof plates (4).
) is closely fitted and supported from the outside to the fitting part (4b) of the cover (7), and the inclined part (7c) protruding diagonally downward and outward from the F edge of the fitting part (7b) of the cover (7) is attached to both roofs. Board (
It is closely supported on the side edge rising portion (4a) of 4).

[Problem B that the invention attempts to solve]

The conventional roof plate connection device for a vertical roof is constructed as described above, and connects the fitting part (7b) of the cover (7) to both roof plates (4).
The cross-sectional shape is almost similar to that of the fitting part (4b) of the cover (7), so that these fitting parts (7b) and (4b) fit closely together, and are continuous with the fitting part (7b) of the cover (7). The sloped part (7c) is connected to the side edge F part (4a) of both roof panels (4).
) is closely supported on top. For this reason, when vertically roofing a roof with an arc-shaped surface such as a semi-cylindrical or tome-shaped roof, the rising side edges (4a) of the roof shingles (4) are sloping, so the roof shingles The radius of curvature R of the arcuate surface is smaller, such as Ion, which has a better ability to follow the arcuate surface of the roof than a roof board made of tile sticks, in which the rising side edges of the roof stand at right angles to the face plate. In some cases, bending the cover may cause distortion, making the fit between the cover and the roof shingles unreliable, making it look unsightly, or causing the fit to come loose and cause leaks. The problem arises that Stiffness is caused by the fact that unless the rising edges of the roof shingles are gradually flattened as the radius of curvature of the arcuate surface of the roof becomes smaller, the ability of the roof shingles to follow the arcuate surface will deteriorate, causing the flattened roof shingles to become stiffer. This is because it is necessary to make the sloped portions of both side plates of the cover follow the side edge-F edges so that these sloped portions are also flattened.

This invention solves the above-mentioned problems and has a semi-cylindrical shape,
Even on roofs that have an arcuate surface such as a dome shape, and the radius of curvature of the arcuate surface is small, the cover can be securely secured to the roof shingles without fear of coming off, and the cover can be installed in a fashionable manner. The purpose of this invention is to provide a plate connecting device that can be easily obtained without complicating the structure.

[Means to solve the problem]

The roof plate connection device for a vertical roof according to the present invention fixes a support fitting on a mounting member such as a purlin material, and attaches the inclined part of both roof plates to be connected to the protrusion protruding on both sides of the intermediate part of the support metal fitting. The fitting part, which has a substantially arc-shaped cross section and extends over the rising side edge part, is supported from the outside, and a part of the part continuous above the fitting part of both roof plates is attached to the part above the middle part of the supporting metal fitting. The supporting metal fittings and the side edges of both roof plates are covered with a long cover, and the lower part of both side plates of this cover is provided with an inclined part projecting diagonally downward and outward, and the protruding edges of these inclined parts. The locking portions are folded back at an acute angle diagonally upward and inward, and the tip edges of these locking portions are engaged from diagonally downward and outwardly to the boundary between the side edge rising portions of both roof panels and the fitting portion. This is a joint support.

(Function) The roof plate connection device for a vertical roof according to the present invention is provided with sloped parts projecting obliquely downward and outward at the lower part of both side edge plates of the cover that covers the side edges of both roof sheets, and the protrusion of these sloped parts is The locking portions are folded back at an acute angle diagonally upward and inward from the edges, and the tip edges of these locking portions are engaged and supported from diagonally downward and outwardly at the boundary between the side edge rising portions and the fitting portions of both roof panels. As a result, even if the cover is curved along an arcuate surface with a small radius of curvature R, such as on a semi-cylindrical or tom-shaped roof, the locking part of the cover is less likely to be distorted, and even slight distortion may occur. Even if I live,
The leading end edge of the locking portion can be reliably locked to the boundary portion.

Therefore, the tip edge of the locking part of the cover will not come off the side edge of the roof plate, so there is no risk of leakage, and the cover will not become unsightly due to distortion. Except for changing the shape of the lower part of both side panels, most of the parts of the conventional roof board connecting device described above can be used as is, and there is no increase in the number of parts.

In addition, when the presser metal fitting (14) is used, its upper protruding piece (14d), supporting surface (14c) and lower protruding piece (1
4e) restricts the movement of the roof board (13), resulting in even stronger fixation.
