[Detailed description of the invention]

[0001]

The present invention relates to a structure in which a glass plate for closing an opening of a window frame is supported on a window frame fixed to a construction surface such as a roof of a building, or a construction surface such as a roof of a building. A skylight that has a structure that supports a glass sheet that closes the opening of a fixed window frame and a glass sheet that closes the opening of the fixed window frame. The present invention relates to a skylight that prevents a glass plate from falling indoors.

2. Description of the Related Art Conventionally, a skylight having a structure in which a window frame fixed to a construction surface such as a rooftop of a building supports a glass plate closing an opening of the window frame, or a construction window such as a rooftop of a building is fixed. In a skylight that has a structure that supports a glass plate that closes the opening of the sash, the sash that opens and closes the opening of the window sash, the window sill and the sash are formed of an extruded aluminum alloy material. The aluminum alloy was exposed on the inner peripheral surface facing the indoor side of the shoji.

[0003]

However, since aluminum alloys are relatively weak to heat, conventional skylights have a problem in that when a fire occurs, the inner peripheral surface of a window frame or a shoji is exposed to a flame that rises indoors. There was a risk that the frames and shojis would be deformed early by the heat of the flame, breaking the glass plate and falling indoors.

[0004]

According to the present invention, as a means for solving the above-mentioned problems, a window frame or a window frame and a shoji are attached to a stainless steel inner peripheral member facing the indoor side and an outdoor side. And an outer peripheral component member made of an aluminum alloy facing the above.

[0005]

[Operation and effect of the invention] When a flame rises indoors due to the occurrence of a fire, the inner peripheral components of the window frame and the shoji are exposed to the flame, and the inner peripheral components are more excellent in heat resistance than aluminum alloy. Made of stainless steel. Therefore, when compared to a conventional skylight whose inner periphery exposed to the flame of a window frame or shoji is made of an aluminum alloy, deformation of the window frame or shoji due to the heat of the flame is less likely to occur. There is an effect that it is possible to prevent the glass plate from falling into the room early due to thermal deformation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. A window frame 2 having a rectangular shape is fixed to a window hole 1 provided on the roof surface of a building. The window frame 2 is made of stainless steel and has a gutter portion 4 formed on the inside of the lower end edge thereof (corresponding to an inner circumferential component which is a component of the present invention) 3 and alumite-treated. A frame outer peripheral component (corresponding to an outer peripheral component which is a component of the present invention) 5 which is made of an aluminum alloy and has a draining inclined portion 6 protruding outward at a lower end edge thereof; 5 and a heat insulating material 7 sandwiched between them. The window frame 2 has a stainless steel fixing bracket fixed to the gutter portion 4 of the frame inner peripheral structure 3 by a stainless steel rivet 8 and fitted to the draining slope 6 of the frame outer peripheral structure 5. The window frame 2 is fixed to a building by welding the fixing bracket 9 to a streak 10 provided on the periphery of the window hole 1 and joining the bracket to the building.

A window 15 for opening and closing the opening 12 is mounted on the window frame 2 while being supported by an opening / closing drive member (not shown) made of stainless steel. The frame of this shoji 15 is made of a stainless steel frame inner peripheral component (corresponding to the inner peripheral component which is a component of the present invention) 17 and anodized aluminum alloy. 1
A frame outer peripheral component 18 (corresponding to an outer peripheral component which is a component of the present invention) on which a frame 9 is formed;
8 and a heat insulating material 20 sandwiched between them.

On the frame of the shoji 15, a stainless steel bolt 21 is fixed to the upper end of the frame inner peripheral structure 17 with a stainless steel bolt 21 and projects outward to cover the upper end of the frame outer peripheral structure 18. The glass receiving bracket 22 is attached. Further, inside the opening 23 of the frame of the shoji 15, a stainless steel glass receiving frame 24, which has a cross shape in a plan view and divides the opening 23 into four parts, has a stainless steel bracket 25 at its end. It is provided by fixing to the frame inner peripheral structure 17 using a stainless steel bolt 26 and a stainless steel bolt 26.

In each of the four openings 23a defined by the glass receiving frame 24, a glass plate 28 is attached to the periphery of the glass receiving bracket 2 where the packing 29 is fitted.
2 and a stainless steel plate-shaped glass holding bracket 30, and between the glass receiving frame 24 and a stainless steel L-shaped glass holding bracket 31. ing.

Further, an acrylic dome 35 covering the upper part of the shoji 15 is fixed by mounting the peripheral portion of the acrylic dome 35 on the glass holding bracket 30 via a spacer 36 and connecting it with a stainless steel bolt 37. Has been established.

The skylight of this embodiment has the window frame 2 as described above.
The surface facing the indoor side of the sliding door 15 is entirely made of stainless steel members, and the surface facing the indoor side of the shoji 15 and the portion supporting the glass plate 28 are all made of stainless steel members. ing.

For this reason, when a fire occurs, it is the above stainless steel portion that is exposed to the flaming flame standing indoors, and the aluminum alloy portion on the outdoor side is exposed to the flame. Never. Since stainless steel has better heat resistance than aluminum alloy, the window frame and the shoji screen are made of aluminum frame 2 compared with the conventional skylight.
The window frame 2 and the shoji 1 are hardly deformed by heat of the shoji and the shoji 15.
The dangerous situation that the glass plate 28 falls indoors due to the thermal deformation of 5 is avoided for a long time after the fire occurs.

In this embodiment, the opening 23 of the shoji 15
Are divided into four, and the glass plates 28 are fixed to each other, so that the glass plate is hard to be broken as compared with a structure in which one large-sized glass plate is fixed to a shoji.

In this embodiment, a case where the present invention is applied to an openable skylight provided with a shoji 15 for opening and closing the opening 12 of the window frame 2 has been described. It can also be applied to a fitting-type skylight supporting the above.
