[Conventional technology]

Conventionally, Japanese Patent Application Laid-Open No.
There was one shown in Japanese Patent No. 2760. As shown in FIG. 3, the shingle connecting device supports and fixes an attachment portion (3a) of a support fitting (3) on an attachment member having a base material (2) laid on a purlin material (1). A substantially semi-circular cross-section is provided on the sloped side edge rising portion (4a) of both shingles (4) to be connected to the projecting portion (3b) projecting at the middle in the vertical direction of the support bracket (3). The joint (4b) is fitted and supported from the outside. Further, the holding member (5) is supported and fixed to the supporting member (3) by an appropriate means, and a space opened downward by the side plate (5a) of the holding member (5) and the upper part (3c) of the supporting member (3). A part (6) is formed, and a folded part (4c) that is continuous above the fitting part (4b) of the both shingles (4) is fitted into these space parts (6). 4c) is supported by the side plate (5a) of the holding member (5) and the upper part (3c) of the supporting member (3). Further, the side edges of the presser fitting (5) and the both shingles (4) are covered with a long cover (7), and the cover (7) has a substantially semi-circular cross section provided under the both side plates (7a). The fitting portion (7b) is brought into surface contact with the fitting portion (4b) of both roof plates (4) from outside to fit and support the fitting portion (7b), and obliquely downward from the lower edge of the fitting portion (7b) of the cover (7). The sloping part (7c) protruding to the side edge rising part (4a) of both shingles (4)
It is supported by surface contact on the top.

[Problems to be solved by the invention]

The conventional roof shingle connection device for a vertical roof is configured as described above, and the fitting portion (7b) of the cover (7) is connected to both shingles (4).
The fitting section (4b) has a cross section substantially similar to that of the fitting section (4b), and the fitting sections (7b) and (4b) are brought into surface contact with each other, and fitted to the fitting section (7b) of the cover (7). Continuous ramp (7
c) is supported on the side edge rising portions (4a) of both shingles (4) in surface contact. For this reason, for example, kamaboko,
When vertically roofing an arc-shaped roof such as a dome-shaped roof, the side edge rising portion (4a) of the roof plate (4) is inclined, so that the side edge rising portion of the roof plate is separated from the face plate portion. Compared to a roofing plate with a tiled roof that stands upright at a right angle, it has better followability to the arcuate surface of the roof.

However, as the radius of curvature of the arcuate surface of the roof becomes smaller, in order to have the ability to follow the arcuate surface, in order to gradually flatten the rising edge of the side edge of the shingle, the following problems occur. there were.

First, by making the slopes of the cover follow the rising edge of the side edge of the flattened roof shingle, and flattening these slopes, the fitting between the fitting part of the cover and the fitting part of the roof shingle becomes impossible. This causes uncertainty, a problem that the appearance is deteriorated, the fitting is disengaged, and a leak is caused.

In addition, if the cover is distorted as a result of R processing or the like in which the cover is bent by following the radius of curvature of the arcuate surface of the roof, the surface contact between the fitting portion and the inclined portion with a slight space and the roof plate is formed. The portion becomes “floating” and the lower part of the minute gap is opened to facilitate infiltration of rainwater, the fitting force is weakened, and the cover may be scattered by wind pressure.

The present invention solves the above-mentioned problems, and even if the roof has an arc-shaped surface such as a semi-cylindrical shape or a dome shape and has a small radius of curvature of the arc-shaped surface, the cover is securely locked to the roof plate without fear of coming off. It is an object of the present invention to provide a roof shingle connecting device for a roof that can be fitted and that can be fitted with a cover, without complicating the structure.

[Means for solving the problem]

The roof shingle connection device for a vertically-roofed roof according to the present invention is configured such that a support bracket is fixed on an attachment member such as a purlin material, and side edges of the roof shingles connected to projections protruding from both sides of an intermediate portion of the support bracket. A fitting part having a substantially arc-shaped cross section connected to the rising part is supported from the outside, and a part of a part of the two roof plates that is continuous above the fitting part is supported by a part above the middle part of the support bracket. Then, cover the side edges of the support bracket and both roof plates with a long cover, and from the lower portions of both side plates of the cover to diagonally downward and outward, respectively, to the vicinity of the boundary between the face plate portion of the roof plate and the side edge rising portion. The projecting inclined portions and the engaging portions which are bent at an acute angle inwardly upward from the projecting edges of these inclined portions are formed, and the leading edge portions of these engaging portions are obliquely downwardly outwardly from both roof plates. It is engaged and supported at the boundary between the side edge rising part and the fitting part. That.

[Action]

The roof-panel connection device for a vertical roof according to the present invention includes a cover covering the side edges of both roof plates, from a lower portion on both sides of the cover to a portion near a boundary between a face plate portion of the roof plate and a side edge rising portion diagonally downward and outward. Since the protruding slopes are provided, the protruding edges of these slopes are obliquely below and outside the boundary between the side edge rising portions and the fitting portions of the both shingles, and from the side edge rising portions of the roof plate. They are located at a distance. Since the engaging portions are formed by bending the projecting edges of these inclined portions obliquely upward and inward to form the engaging portions, the leading edge portions of these engaging portions are formed at the boundary portions between the side edge rising portions of both roof plates and the fitting portions. , From the diagonally lower outer side.

As a result, it is possible to form a gap portion in which the interval is increased toward the fitting portion of the roof shingle by the inclined portion and the locking portion of the cover and the roof shingle.

Even if the gap is widened toward the fitting part of the shingle, the inclination angle of the side edge rising portion of the shingle is flattened by the R processing, and even if the cover is made to follow the R processing of the shingle, The leading edge of the locking portion can be secured to the boundary without falling off the boundary between the side edge rising portion of the roof panel and the fitting portion.

In addition, the gap is widened toward the fitting portion of the roof shingle so that the cover and the roof shingle do not come into surface contact with each other. The surface contact portion between the cover and the shingle is in a “floating” state, and the problem that the fitting force is weakened does not occur.

In addition, even if distortion occurs due to R processing or the like, the leading edge of the locking portion engages from the diagonally lower outside with the boundary between the side edge rising portion and the fitting portion of both roof plates. As a result, the cover can be securely locked to the boundary portion, and the leading edge of the locking portion of the cover does not come off the side edge of the shingle, and there is no danger of rain leakage.

In addition to these functions and effects, the inclined part of the cover
It protrudes from the lower part of both sides of the cover to the vicinity of the boundary between the face plate part and the side edge rising part of the roof plate, and since the cover can be securely locked to the roof plate as described above, regardless of the presence or absence of R processing etc. In addition, it is possible to give a stable design in appearance.

In addition, except changing the shape of the lower part of both sides of the cover,
Roof shingles that can be used almost as-is with conventional roof shingle connection devices, do not increase the number of parts, and are therefore easily obtained without complicating the structure, and are suitable for roofs with arc-shaped surfaces such as kamaboko and dome shapes It is a connection device.

Further, when the holding metal is used, the upper protruding piece, the support surface, and the lower protruding piece regulate the movement of the roof shingle, so that a more secure fixing can be obtained.

May be appropriately supported by one or both of the side plate of the presser fitting and the upper part of the support fitting, for example, by supporting the support fitting on the lower surface of the upper protrusion.

〔The invention's effect〕

As described above, the roof shingle connecting device according to the present invention includes a roof shingle and a side hem, each of which extends obliquely downward and outward from a lower part of both sides of a cover that covers the side rims of both roof shingles. Since the inclined portions protruding to the vicinity of the boundary of the rising portion are provided, the projecting edges of these inclined portions are diagonally below and outside the boundary between the side edge rising portions of both shingles and the fitting portion, and
It is located away from the side edge rising portion of the shingle. Since the engaging portions are formed by turning the projecting edges of these inclined portions obliquely upward and inward to form the engaging portions, the leading edge portions of these engaging portions are formed at the boundary between the side edge rising portions of both roof plates and the fitting portion. , From the diagonally lower outer side.

As a result, it is possible to form a gap portion in which the interval is increased toward the fitting portion of the roof shingle by the inclined portion and the locking portion of the cover and the roof shingle.

Even if the gap is widened toward the fitting part of the shingle, the inclination angle of the side edge rising portion of the shingle is flattened by the R processing, and even if the cover is made to follow the R processing of the shingle, The leading edge of the locking portion can be secured to the boundary without falling off the boundary between the side edge rising portion of the roof panel and the fitting portion.

In addition, the gap is widened toward the fitting portion of the roof shingle so that the cover and the roof shingle do not come into surface contact with each other. The surface contact portion between the cover and the shingle is in a “floating” state, and the problem that the fitting force is weakened does not occur.

In addition, even if distortion occurs due to the R processing or the like, the leading edge of the locking portion engages with the side edge rising portion, the fitting portion, and the boundary portion of both roof plates from diagonally below and outside. As a result, the cover can be securely locked to the boundary portion, and the leading edge of the locking portion of the cover does not come off the side edge of the shingle, and there is no danger of rain leakage.

In addition to these functions and effects, the inclined part of the cover
It protrudes from the lower part of both sides of the cover to the vicinity of the boundary between the face plate part and the side edge rising part of the roof plate, and since the cover can be securely locked to the roof plate as described above, regardless of the presence or absence of R processing etc. In addition, it is possible to give a stable design in appearance.

In addition, except changing the shape of the lower part of both sides of the cover,
Roof shingles that can be used almost as-is with conventional roof shingle connection devices, do not increase the number of parts, and are therefore easily obtained without complicating the structure, and are suitable for roofs with arc-shaped surfaces such as kamaboko and dome shapes It is a connection device.

Further, when the holding metal is used, the upper protruding piece, the support surface, and the lower protruding piece regulate the movement of the roof shingle, so that a more secure fixing can be obtained.
