Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a skylight device installed on the roof of a house, and particularly to a skylight device suitably employed in a roof covered with Japanese tiles.

(Prior art) Recently, an increasing number of houses are equipped with skylight devices on the roof for both lighting and ventilation.
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 easily and neatly installed on a Western-style roof covered with flat asbestos tiles, it cannot be installed on an uneven roof 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. However, in this case, there is a problem in that manufacturing and construction of the dome frame, especially the rain protection by sheet metal processing, etc., is time consuming and the labor cost increases significantly.

(Purpose of the invention) This invention was made in view of the above circumstances, and its purpose is to easily install and install a roof covered with uneven tiles such as Japanese tiles that will protect against rain. Our goal is to provide a convenient skylight device that can.

(Means for achieving the purpose) In order to achieve the above purpose, the skylight device of the present invention has a structure in which an apron that can be bent freely is provided at the edge of the dome frame supporting the daylighting dome on the underwater side. The gist of this is that

(Operations and Effects) In the skylight device having this structure, first, the dome frame supporting the daylighting dome is fixed to the periphery of the opening of the roof, and then the Japanese tiles are fixed so as not to overlap the edge of the dome frame on the underwater side. In addition, lay the apron around the dome frame so that it overlaps the edges other than the underwater side, and finally place the apron installed on the underwater side edge of the dome frame on top of the Japanese tiles on the underwater side. By stacking them and bending them to almost follow the corrugated surface, it can be attached to an uneven roof covered with Japanese tiles, etc., so a special dome frame is made on site from concrete, wood, etc. Performing sheet metal processing around the dome frame to protect against rain eliminates the need for such troublesome work, thus improving construction efficiency and suppressing increases in labor costs.

Moreover, if the apron provided at the edge of the dome frame on the underwater side is stacked on top of the Japanese roof tiles, etc. on the underwater side as described above, and bent to almost follow the wavy surface of the roof tiles,
Rainwater flowing from the Japanese roof tiles on the water side passes from the water side edge of the dome frame to the left and right edges.
Furthermore, since rainwater flows smoothly down to the Japanese roof tiles etc. on the water side below the water through the top of the apron, rainwater does not accumulate on the water side edge of the dome frame. in this way,
The apron prevents rainwater from accumulating on the underside of the water, which is the biggest problem when it comes to rainwater management, so there is no risk of rainwater entering the house along the underside of the Japanese tiles on the underside of the water and causing rain leaks. All become equal to nothing.

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

(Example) Fig. 1 is an exploded perspective view showing an embodiment of a skylight device according to the present invention, Fig. 2 is a perspective view of essential parts of the same embodiment,
FIG. 3 is a perspective view showing the installed state of the same embodiment, and as shown in FIG.
and a dome frame 2 that supports these domes.

Both the daylighting domes 1a and 1b have a rectangular planar shape made of high-strength synthetic resin such as polycarbonate, and the outer dome 1a is a dome with a highly transparent octagonal central raised part, and the inner dome is a dome with a highly transparent octagonal central ridge. Each of the domes 1b is formed into a dome with a milky-white translucent round central ridge. These daylighting domes 1a and 1b are fixed to the dome frame 2 with appropriate fasteners (not shown) through packing (not shown) or the like, and the outer dome 1a
An excellent heat insulating effect is exhibited by the air heat insulating layer formed between the inner dome 1b and the inner dome 1b.

It goes without saying that there may be only one lighting dome, or that the dome may be attached to the dome frame 2 so as to be openable and closable.

The dome frame 2 is a high-strength frame integrally molded into a rectangular trapezoid shape using FRP or the like, and has flange-shaped end edges 21a, 21b, 21c, and 21d formed around the periphery, and the end facing above the water. A drain groove 22 is formed in a U-shape from the edge 21b to the edge portions 21a and 21c on both sides. The drain groove 22 is deepest at the upper edge 21b and gradually becomes shallower as it approaches the lower edge 21d.
d, it is configured to disappear. Furthermore, a heat insulating material (not shown) or the like is adhered to the inner surface of the dome frame 2.

An apron 3, which is the most distinctive feature of the present invention, is provided at the end edge 21d of the dome frame 2 on the underwater side. This apron 3 is made of a bendable metal plate, such as a lead plate, for example, and as shown in FIG.
d is fixed to the lower surface of the housing via a waterproof gasket 4 with a fastener 5 such as a blind rivet. There is no particular restriction on the size of this apron 3, but in order to ensure rain protection, it is necessary to
It is desirable to set the protrusion length l from 1d to the tip of the apron 3 to be about 35 to 40 cm, which is approximately the same as the size of the Japanese tile, and also ensure that both ends of the apron 3 are at the left and right edges 21a of the dome frame. , 21c is desirable.

As the apron 3, in addition to the lead plate described above, for example, a flexible thick synthetic resin sheet, an ultraviolet curable FRP sheet, etc. can also be used.

When using a skylight device with such a configuration and installing it on a roof made of Japanese tiles, as shown in FIG. The Japanese tiles 6 are fixed to the periphery of the opening of the roof at the dome frame so as not to overlap the edge 21d of the dome frame below the water, and the edge 21 of the dome frame other than the edge 21 below the water.
a, 21b, and 21c are laid around the dome frame 2 so as to overlap, and finally, the apron 3 at the edge 21d on the underwater side of the dome frame 2 is placed on top of the Japanese tiles 6 in the first row on the underwater side. All you have to do is overlap it and bend it so that it almost follows the waveform surface. In that case, between the apron 3 and the tiles 6 on the underwater side, and the left and right edges 2 of the dome frame 2
It is desirable to interpose caulking material between 1a, 21c and the tiles 6 on both sides to ensure rain protection.

This skylight device can be easily installed on a Japanese tile roof as described above, and there is no need for the conventional troublesome work such as manufacturing a special dome frame and processing sheet metal around the dome frame to cover the rain. Therefore,
Construction efficiency will be significantly improved, and increases in labor costs will also be suppressed.

Moreover, as described above, this skylight device is bent so that the apron 3 provided at the edge 21d on the underwater side of the dome frame 2 is overlapped on the Japanese tiles 6 on the underwater side and roughly follows the waveform surface of the apron 3. Therefore, Japanese tiles 6 on the water side
The rainwater flowing from the dome frame 2 passes through the drainage ditch 22 formed from the water-side edge 21b to the left and right edges 21a, 21c, and then passes over the apron to reach the Japanese tiles 6 on the water-bottom side. flowing down smoothly,
Rainwater no longer accumulates on the lower end edge 21d of the dome frame 2. In this way, the apron 3 prevents rainwater from accumulating on the underside of the water, which is the biggest problem when it comes to rainwater, so rainwater does not infiltrate indoors along the underside of the Japanese tiles 6 on the underside of the water. There is almost no risk of rain leaks.
