Description of the Related Art Conventionally, a skylight provided on a roof or the like in order to improve the daylighting of a building indoors has a formwork made of a material such as aluminum which is lightweight and has excellent appearance and corrosion resistance. Is used. However, this formwork
When exposed to high temperatures in the event of a fire, the glass tends to be thermally deformed, and there is a risk that the glass plate or the like closing the opening of the roof may fall off and fall indoors, and therefore various measures have been taken.

[0003] For example, the "skylight" disclosed in Japanese Utility Model Laid-Open No. 5-12524 by the inventor of the present invention has filed an acrylic dome, a glass plate or the like on the upper surface of an aluminum mold. A glass-filled concrete is attached to the indoor surface of the formwork with a skylight fitted with a daylight closing plate and the lower end of the formwork fitted to an opening provided on a horizontal surface or a slope such as a building roof. It is characterized in that a fire-resistant insulation board such as a board or a gypsum board is stuck. That is, as shown in FIG. 3, in the above-mentioned skylight 1, a meshed glass plate 5 whose periphery is covered with a packing 7 on a flange 1 c provided at the upper end of an aluminum mold 1 a, and an acrylic dome 6, the holding frame 2 that presses the outer peripheral portion of the acrylic dome against the flange 1c via a packing 8 is fixed to the mold frame 1a by bolts 3. ing. A glass fiber-containing concrete plate or a gypsum board 4 as a fire-resistant heat insulating plate is adhered to the indoor surface of the mold 1a so that the aluminum mold 1a is not easily thermally deformed when a fire occurs. And fire resistance is enhanced.

[0004]

However, in the above-mentioned skylight, a concrete plate or a gypsum board 4 containing glass fiber is adhered to the indoor side surface of the formwork 1a. There is a problem that the appearance when looked up from the indoor is not beautiful. In the above-mentioned skylight 1, a gap is provided between the end surface of the glass fiber-containing concrete plate or the gypsum board 4 and the surface of the mesh-containing glass plate 5. As a result, the high-temperature atmosphere caused by the fire wraps around the end face of the glass fiber-containing concrete plate or the gypsum board 4 and the packing 7
Or the flange 1c, which may be thermally deformed. In addition, glass fiber-containing concrete boards and gypsum boards have limitations in their formability, so they cannot follow the complicated shape of the formwork, and cannot cover the entire indoor surface of the formwork. There were also points. In addition, the above-mentioned skylight has a structure in which the acrylic dome 6 and the meshed glass 5 are overlapped with each other and pressed against the flange 1c by the holding frame 2 so as to be watertight.
Alternatively, even if any of the packings 8 is deteriorated, there is a problem that the watertight performance is reduced.

Therefore, the present invention has been made in view of the above-described problems, and is excellent in aesthetic appearance when a skylight is looked up from indoors, as well as in fire resistance when a fire occurs and in watertightness. The purpose is to provide excellent skylights.

[0006]

In order to solve the above-mentioned problems, a skylight according to the present invention has a daylight closing plate attached to the upper end of a mold in a liquid-tight manner, and the daylight closing plate is attached to a roof of a building. In a skylight having the formwork attached to a building so as to face an opening provided in a building or the like, a support portion for supporting a glass plate with a net closing the opening is provided on a surface facing the indoor side of the formwork. In addition, the indoor surface of the bearing and the formwork is covered with a metal plate. In addition, the metal plate is extended so as to be in contact with the netted glass. Further, the metal plate is attached to the bearing portion or the surface of the formwork with a gap therebetween. In addition, a heat insulating material is interposed between the metal plate and the bearing or the formwork.

[0007]

The metal plate of the skylight according to the present invention covers the indoor surface of the bearing portion and the formwork to improve the aesthetic appearance, and shields the support portion and the formwork by shielding the high-temperature atmosphere caused by fire. Protect. Further, the metal plate extended so as to be in contact with the meshed glass prevents the high-temperature atmosphere due to the fire together with the meshed glass from going around from the end face of the meshed glass toward the daylighting closing plate. Further, a gap between the metal plate and the support portion or the formwork shields a high-temperature atmosphere caused by a fire to protect the support portion or the formwork. Similarly, a heat insulating material interposed between the metal plate and the bearing portion or the formwork shields a high-temperature atmosphere caused by a fire to protect the bearing portion or the formwork.
