Description

[Detailed description of the invention]       [0001]     [Technical field to which the invention belongs]   The present invention relates to a skylight mounted on a building roof or the like.       [0002]     [Prior art]   2. Description of the Related Art Conventionally, a skylight is attached to a roof or the like of a building for the purpose of lighting. But However, with a typical skylight, the temperature difference between the indoor temperature and the outdoor temperature Condensation forms on the inner surface of the window frame and on the indoor-side light-transmitting plate, and falls into the room as water droplets There was something.       [0003]   Therefore, Japanese Patent Application Laid-Open No. 11-280213 and Japanese Patent Application Laid-Open No. Discloses a skylight that prevents the occurrence of dew condensation with a heat insulating material.       [0004]     [Problems to be solved by the invention]   However, in these skylights, the airtightness of the outdoor side and the indoor side, The heat insulation of the material itself was insufficient.       [0005]   The present invention aims to solve this problem.       [0006]     [Means for Solving the Problems]   The gist of the present invention is that the inside of the external fixing frame is surrounded by an airtight The indoor-side light-transmitting plate covered with the dome is fixed. A ceiling having an outdoor-side light-transmitting plate having a shape and an internal fixing frame below the indoor-side light-transmitting plate A window, the indoor-side light-transmitting plate has a hollow shape, and an inner fixed frame has a hole for dew condensation. In the skylight with       [0007]     [Embodiment of the invention]   The skylight of the present invention is made of an airtight The indoor-side light-transmitting plate covered with the dome is fixed. A shape having an outdoor-side light-transmitting plate and an internal fixed frame below the indoor-side light-transmitting plate It is.       [0008]   The outer shape of the external fixed frame may be circular or polygonal. Outside Examples of the material of the fixed frame include aluminum, stainless steel, iron, and wood.       [0009]   The indoor-side light-transmitting plate constituting the skylight of the present invention needs to be hollow. As the hollow shape, it has a continuous cylindrical shape or a space between two plate-like objects Shape. The exterior of the indoor-side light-transmitting plate may be circular or polygonal. You may. Polycarbonate, methacryl resin , Polystyrene, glass and the like. Its thickness including the hollow part is 4.5mm It is preferably about 10 to 10 mm. Also, it is possible to stack a plurality of them it can. Install a glass plate or the like on the lower surface side of the indoor side Thus, an air layer can be provided between them.       [0010]   The periphery of the indoor side light transmitting plate is covered with an airtight material. Airtight material indoors It is necessary to have adhesion, airtightness, and weather resistance with the side translucent plate and the indoor fixed frame. The material of the airtight material is ethylene propylene rubber (EPDM), chloroprene Rubber (CR), butyl rubber (IIR) and the like. Its thickness is 1mm to 6m m is preferable.       [0011]   The indoor-side light-transmitting plate, whose peripheral part is covered with an airtight material, Is fixed inside. The heat insulating material is for the indoor side translucent plate whose peripheral part is covered with airtight material. It is preferable that the shape surrounds all the outer edges. As the material of the heat insulating material, Expanded polyethylene resin, expanded polystyrene, expanded polyolefin, glass fiber, Urethane and the like. Its thickness is preferably about 4 mm to 8 mm .       [0012]   A dome-shaped outdoor light-transmitting plate is further provided above the indoor light-transmitting plate. Indoor side transparent By providing a space between the light plate and the dome-shaped outdoor side light-transmitting plate, the present invention Is less likely to cause condensation. The outer shape of the dome-shaped outdoor light-transmitting plate is circular Shape or polygonal shape. Material of dome shaped outdoor side translucent plate Examples include methacrylic resin, polycarbonate, FRP and the like. these Is a dome shaped outdoor translucent plate that can withstand loads such as wind and snow from outside It preferably has strength. Its thickness is preferably about 2 mm to 6 mm New       [0013]   In addition, an inner fixed frame is provided below the indoor-side light-transmitting plate. The outer shape of the internal fixed frame is a circle It may be a shape or a polygonal shape. Inside to take in external light The fixed frame preferably has a shape that exists only near the outer edge of the indoor-side light-transmitting plate. . Examples of the material of the inner fixed frame include aluminum, stainless steel, iron, and wood. You.       [0014]   The skylight of the present invention has a structure that hardly causes dew condensation. In order to prevent the dew condensation, the internal fixing frame has holes for dew condensation. The tip of the hole for dew condensation And a drain pipe. Condensation water falls inside the drain pipe It is preferable that the wastewater is treated without being treated. When the end of the drain pipe is outside the room To prevent outside air (cold air) from entering the room from the end of the drain pipe. Preferably.       [0015]     【Example】   Hereinafter, embodiments of the present invention will be described with reference to the drawings.       [0016]   [Example 1]   1 to 4 show an embodiment of a skylight having a square outer shape.       [0017]   FIG. 1 is a top view of a skylight.       [0018]   Fig. 2 shows a dome-shaped outdoor-side translucent plate removed from the skylight, and each layer is viewed from above. It is a top view. If necessary, cut each layer so that the lower layer can be seen. You.       [0019]   FIG. 3 is a vertical sectional front view of the skylight structure.       [0020]   FIG. 4 is an enlarged vertical sectional front view of the main part.       [0021]   In FIG. 4, a hollow indoor-side light-transmitting plate 1 made of polycarbonate is made of foamed EP. The peripheral part is covered with an airtight material 2 made of DM, and an external fixing frame made of aluminum 3 is fixed via a heat insulating material 4 made of foamed polyethylene. It is fixed inside the internal fixing frame 5 made of Mi.       [0022]   In order to further enhance the heat insulation, the inner fixed frame 5 has a thermocouple on the lower surface of the indoor side light transmitting plate 1. The glass plate 7 is fixed with an air layer having a small flow.       [0023]   By tightening the aluminum translucent plate retainer 6 with screws, the airtight material 2 and the inner solid The fixed frame 5 is further adhered to improve the airtightness.       [0024]   The outer fixed frame 3 and the inner fixed frame 5 are airtight and heat-tight by the airtight material 2 and the heat insulating material 4. It is electrically insulated, has little heat flow into and out of the room, and has the convection and The convection in the air layer between the indoor-side translucent plate 1 and the glass plate 7 is reduced, and the inner fixed frame 5 and Prevents condensation on the surface of the glass plate 7.       [0025]   A dome-shaped outdoor light-transmitting plate made of methacrylic resin is provided on the indoor light-transmitting plate 1. By fixing 8, heat loss of the indoor side translucent plate 1 due to outdoor wind is prevented.       [0026]   Even if dew condensation occurs on the outer peripheral portion of the indoor surface of the glass plate 7 where dew condensation is likely to occur, The part fixing frame 5 receives the dew condensation, and passes the drain pipe 10 through the hole 9 made of aluminum dew. Drained.       [0027] [Effect of the invention]   The skylight of the present invention covers the interior of the indoor side translucent plate with airtight material, No outside air enters the hollow of the hollow indoor side light-transmitting plate, and the outside air Insulation is used to prevent air from entering, reducing air convection and cutting Increases heat and prevents condensation. Even if dew condensation occurs, no condensation Condensation is discharged from the holes, and it is hygienic and safe.
