Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a structure for attaching a skylight device to the roof of a house, in which an apron is provided on the edge of a dome frame supporting a daylighting dome on the underwater side. This invention relates to a mounting structure suitable for mounting on a roof covered with Japanese tiles.

Conventional technology and its problems Recently, an increasing number of houses are equipped with skylight devices installed on the roof for both lighting and ventilation, and as a skylight device,
A synthetic resin daylighting dome and supporting the dome
Commercially available products consisting of an FRP dome frame are widely used.

However, although the above-mentioned skylight device can be installed easily and neatly on Western-style roofs covered with flat asbestos tiles, it cannot be installed on uneven roofs covered with Japanese tiles. For
The drawback is that it is difficult to install the FRP dome frame to protect it from rain. Therefore, in the case of a roof covered with Japanese tiles, etc., a wooden or concrete dome frame is specially installed around the opening edge to improve rain protection, and an aluminum support frame is placed on top of this dome frame. In this case, the dome frame is manufactured, installed,
In particular, there is a problem in that it takes a lot of time and effort to cover up the rain by sheet metal processing, etc., and the labor costs increase significantly.

Purpose of the invention This invention was made in view of the above circumstances.
The purpose is to provide a mounting structure for a skylight device that can be installed easily and with good rain protection on a roof covered with uneven tiles such as Japanese tiles.

Means for Achieving the Object In order to achieve the above object, the mounting structure of the skylight device according to the present invention is such that an apron is provided on the edge of the dome frame supporting the daylighting dome on the underwater side, and the dome is provided with an apron. The above-mentioned apron has a skylight device in which a drainage groove is formed on the edge of the frame except for the edge on the underwater side, which is fixed to an opening in the roof, and the waveform is bent to approximately match the uneven shape of the tile. The corrugated leading edge of the apron is placed over the roof tile on the underwater side of the skylight device, and the rear edge of the apron is positioned at the same height as or higher than the concave part of the corrugated leading edge. It is said that

Effects of the Idea With this mounting structure, rainwater flowing from the tiles on the water side is formed from the edge on the water side of the dome frame, excluding the edge on the water side, to the edges on both the left and right ends. The water flows through the drainage ditch, and then passes over the apron and flows down from the recess in the corrugated leading edge to the roof tiles below. By positioning it higher, the rainwater flow path above the apron does not have a reverse slope, and rainwater does not accumulate on the apron, so rainwater flowing from the water side is prevented. All of the water flows smoothly down to the tiles on the lower side of the water. In this way, the accumulation of rainwater on the bottom side, which is the biggest problem in rain control, is prevented by an apron with no reverse slope, so rainwater does not enter the house along the underside of the tiles on the bottom side. There is almost no risk of rain leaking.

In addition, during construction, the skylight device is fixed to the opening in the roof, tiles are laid in layers on the underwater side of the dome frame and on the edges on both left and right sides, and roof tiles are installed on the edge of the dome frame on the underwater side. Installation can be completed by simply overlaying the corrugated edge of the apron on the tile below the water, so if you fabricate a special dome frame on site from concrete or wood and perform sheet metal processing to protect it from rain, it will be easy to install. This eliminates the need for any troublesome work, making it possible to improve construction efficiency and reduce labor costs.

Example Hereinafter, the present invention will be described in detail with reference to Examples.

FIG. 1 is a perspective view showing an embodiment of a mounting structure for a skylight device according to the present invention, and FIG. 2 is a sectional view taken along the line -- in FIG. ing.

As shown in FIG.
0b and the dome frame 11 that supports these domes.
And, the edge part 11 which becomes the underwater side of this dome frame 11
d.

Both of the daylighting domes 10a and 10b have a rectangular planar shape made of high-strength synthetic resin such as polycarbonate, and the outer dome 10a is a dome with a highly transparent octagonal central raised part, The domes 10b each have a milky-white translucent round central bulge. These lighting domes 10a, 1
0b is fixed on the dome frame 11 with a suitable fastener (not shown) via a packing (not shown) or the like, and is connected to the air insulating layer 13 formed between the outer dome 10a and the inner dome 10b. The structure is designed to exhibit excellent heat insulation effects. still,
The lighting dome may be only an outer dome, or may be attached to the dome frame 11 so as to be openable and closable.

The dome frame 11 is a high-strength frame integrally shaped into a rectangular trapezoid shape using FRP or the like, and has flange-shaped end edges 11a, 11b, 11c, and 11d formed around the periphery, and is on the underwater side. Edge portions 11a on both sides from the edge portion 11b on the water side excluding the edge portion 11d,
A drain groove 11e is formed in a U-shape extending to 11c. This drain groove 11e has an upper end edge 11
It is configured so that it is deepest at point b, gradually becomes shallower as it approaches the lower end edge 11d, and disappears at the lower end edge 11d. Further, a heat insulating material (not shown) or the like is appropriately attached to the inner surface of the dome frame 11.

The apron 12 provided on the lower end edge 11d of the dome frame 11 is made of, for example, FRP, and has a wavy shape that almost matches the uneven shape of the Japanese tiles 3. It has a leading edge 12a and a flat trailing edge 12b.
As shown in FIG. 4, this flat rear edge 12b is fixed to the lower surface of the underwater side edge 11d of the dome frame 11 via a waterproof gasket 14 with a fastener 15 such as a blind rivet. As a result, it is attached to the lower end edge portion 11d in a watertight manner. The size of this apron is the dome frame 11 as shown above.
When attached to the lower end edge 11d of the apron 12, the protruding length from the lower end edge 11d to the tip of the apron 12 is approximately 1.5 times the vertical dimension of the Japanese tile (approximately
55 to 60 cm), and both ends of the apron 12 are set to the left and right edges 11 of the dome frame 11.
It is set to slightly protrude from a and 11b.

The present invention provides four edge portions 11a, 11b, 11c, 1 of the dome frame 11 of the skylight device 1 as described above.
1d to the periphery of the roof opening 2 with appropriate fasteners (not shown) as shown in FIG. 2, and as shown in FIG. and the left and right edge parts 11a and 11c, while laying Japanese tiles 3 from the second row without laying Japanese tiles in the first row on the underwater side, and laying Japanese tiles 3 from the second row. By overlaying the wavy tip edge 12a of the apron 12 on top of the Japanese tiles 3, the rear edge 12b of the apron 12 forms the recess 1 of the wavy tip edge 12a, as shown in FIG.
It is installed so that it is located at the same height as 2c or higher than that. Therefore, in this installed state, the rainwater flow path above the apron will not have a reverse slope. Although not shown,
Caulking material or the like is interposed between the apron 12 and the Japanese tiles 3 on the underwater side, and between the left and right edges 11a, 11c of the dome frame 11 and the Japanese tiles 3 on both sides, to more reliably keep out the rain. It is desirable to do so.

With the above-described mounting structure, rainwater flowing from the Japanese tiles 3 on the water side flows through the drainage groove 11e formed from the water side edge 11b of the dome frame 11 to the left and right edges 11a, 11c, Furthermore, it passes over the apron 12 and flows down from the recess 12c of the corrugated tip edge 12a to the tile on the water side, but in that case,
As mentioned above, the rainwater flow path above the apron 12 is prevented from having a reverse slope, so the rainwater flowing from the water side does not stay on the water side apron 12 and flows smoothly. It flows down to the tiles on the water side.

Furthermore, with the above-mentioned mounting structure, there is no need for any troublesome work such as manufacturing a special dome frame from concrete, wood, etc. on site and applying sheet metal processing for rain protection.

Effects of the Invention As is clear from the above explanation, according to the mounting structure of the skylight device of the present invention, rainwater flows through the drain groove formed at the edge of the dome frame except for the edge below the water. As the rainwater flows down, the apron, which has no reverse slope, prevents rainwater from accumulating on the underside of the skylight system, which is the biggest problem in rain control, so the rainwater flows indoors along the underside of the tiles on the underside. There is almost no risk of rain leaking due to intrusion, and there is no need for troublesome work such as making a special dome frame on site from concrete or wood and applying sheet metal processing to prevent rain. As a result, construction efficiency can be greatly improved and labor costs can be reduced.
