2. Description of the Related Art Conventionally, a skylight for daylighting has been installed in an opening such as a roof of a building in order to ensure daylighting, and particularly in a factory, a store, a store, a market, etc., a sufficient amount of daylighting is provided. A large skylight is installed to secure the space. When constructing such a large skylight, it is necessary to increase the size of the opening of the skylight to widen the installation portion of the skylight and to provide a large-sized daylighting material.

On the other hand, in the skylight, since dust, dust, mud, etc. gradually accumulate on the surface of the daylighting material due to dust and dust in the air or mud in the rain, it becomes difficult to pass light. In order to efficiently extract light into the room, the shape of the daylighting material is formed into a dome shape with a protruding central part so that dust, dust, mud, etc. on the surface of the daylighting material can flow down, and a structure that can efficiently collect light Many of those that have been adopted are adopted. Further, in such a skylight, in order to prevent the release of thermal energy in the room, to obtain the uniformity of light at the time of lighting, or to improve the fireproof property, a transparent material such as a glass plate is placed inside the dome-shaped daylighting material. A light plate is arranged, and an air layer having a high heat insulating property is secured between the lighting material and the translucent plate to secure the lighting property and to provide a fireproof structure.

However, when the size of the daylighting part is in the range of about 60 cm to 100 cm square, the weight of the glass plate is about the same as that of a general window glass. Therefore, it is relatively easy to handle when it is lifted on the roof and installed on the skylight.
It can be easily installed without any bending,
130 cm or 1 where the size of the lighting unit is 100 cm or more
If the size is as large as 60 cm or 200 cm, it becomes difficult to handle it during transportation or construction because the weight and shape are too large to stretch a single large plate glass plate in the opening. In addition, there is a problem that it is difficult to carry out the construction, and in addition, when it is stretched over the opening, there is a problem that downward bending occurs due to its weight and cracks or the like occur.

Further, if the glass plate is broken or partly damaged during handling or construction, the entire plate must be replaced with a new large-sized glass plate, which is uneconomical. The present invention has been made in view of such problems, and an object of the present invention is to provide a skylight frame body having a large opening area without a translucent plate such as a large-sized glass plate stretched, It is an object of the present invention to provide a skylight device for daylighting in which a transparent plate material having a size obtained by dividing a transparent plate is combined and stretched.
