Description

[Detailed Description of the Invention] The present invention relates to a skylight device for daylighting that has heat insulation properties and prevents condensation.

Since letting in light from the roof of a building is much more efficient than letting in light from the walls, it has recently become popular to install dome-shaped skylights on the roof. . For example, as shown in Figure 1, a skylight for daylighting is installed in a building opening (A) through a mounting frame (B). However, if the skylight for daylighting is single as shown in Figure 1, the insulation effect cannot be obtained, so when installing it in a general house, it is recommended to have two skylights for daylighting as shown in Figure 2. Things are being done to make it heavier. However, in the case of Figure 2, although the insulation properties are improved, since the periphery of the inner skylight for daylighting is exposed to the outside air, condensation is slightly more likely to occur on the indoor side, and the mounting frame is generally made of metal. As a result, dew condensation occurs on the indoor surface, and may even fall as water droplets, and improvements to these problems have been desired.

The present invention was developed in view of this situation, and its gist is an eaves section, a pair of anchor material engaging sections connected to the inner surface of the eaves section, and an eaves section that stands up from the base of the eaves section. A frame material consisting of a vertical wall part that goes up, a top receiving part connected to the top of this vertical wall part, and an intermediate receiving part protruding from the base of the eaves part to the opposite side is used, and this frame material is used for building buildings. A heat insulating material is attached to the opening, covering the indoor side of the anchor engagement part and the intermediate receiving part on the indoor side, and wrapping the intermediate receiving part, and a resilient material is attached to the top of the heat insulating material. The skylight device for daylighting is characterized in that an interior dome is fixed by being clamped with a flexible member, and an exterior dome is further fixed by the top receiving part.

Hereinafter, the present invention will be described in detail with reference to drawings of embodiments.

Reference numeral 1 denotes a frame material made of aluminum or steel for installation used in the present invention, and when it is installed in a building opening 2, it is used in a circular or square shape to match the shape of the opening. This frame member 1 has a cross-sectional shape as shown in FIG. That is, an eave part 11 that is slightly inclined outward, a pair of anchor material engaging parts 12 and 12' continuous to the inner surface of this eave part 11, a vertical wall part 13 rising from the base of the eave part 11, and It consists of a top receiving part 14 connected to the top of the vertical wall part 13, and an intermediate receiving part 15 projecting from the base of the eaves part 11 to the opposite side.

A skylight for daylighting is installed using the frame material 1 constructed as described above. To explain an example of the construction procedure, first, the frame material 1 is attached to the pair of anchor material engaging portions 12, 12'. The anchor 8 is engaged and installed in the building opening 2. Next, a heat insulating material 4 made of foamed synthetic rubber or the like and formed to have a cavity is attached so as to wrap around the anchor material engaging portion 12' and the intermediate receiving portion 15 on the indoor side.
When the heat insulating material 4 is installed in this way, most of the surface of the frame material 1 exposed to the indoor side is shielded,
Moreover, it will also be able to exhibit a heat insulating effect.

When such a state is reached, in the example shown in FIG. 3, the wired glass 4 is fixed above the heat insulating material 4, but as a result, the wired glass 4 is locked with the gasket 6 described below. It will be clamped. If such wired glass is installed, the skylight for daylight will have a triple structure, and there will be two air layers for heat insulation, which will greatly improve the insulation effect, but of course, this wired glass can be omitted. You can also. An interior dome 32 whose periphery is further clamped with an elastic member 6 is fixed to the top of the heat insulating material 4. Further above this, the peripheral edge of the exterior dome 31 is placed on the top receiving portion 14 of the frame member 1, and bolts and nuts 7 are screwed together via the elastic member 6 to fix the exterior dome 31. When the inner dome 32 and the outer dome 31 are fixed in this way, the inner dome 32 is not exposed to the outside air, so that the effect of preventing condensation is higher than that of the conventional structure as shown in FIG. Furthermore, when the interior and exterior domes are fixed in the manner described above, the gap between them can be kept almost constant from the center to the corners, and the heat insulation effect of the air layer is also improved.

The skylight 3 for daylighting used in this invention has a double structure consisting of an exterior dome 31 and an interior dome 32 as shown in the figure, but these are generally made of synthetic materials such as acrylic resin, polycarbonate resin, vinyl chloride resin, or FRP. It is molded into a dome shape from resin material. Of course, the shape of the daylight skylight is not limited to the illustrated example. Note that 9 in the figure is a decorative frame that covers the surface of the heat insulating material 4, and is made of metal such as aluminum or synthetic resin, and is useful for improving the appearance of the room.

Since the present invention has the structure described in detail above, it is possible to obtain excellent heat insulation properties through the daylight skylight consisting of the interior and exterior domes, and because of its structure, the interior dome does not come into contact with the outside air, and moreover, it is possible to Since the surface of the facing frame material is substantially covered with a heat insulating material, the effect of preventing dew condensation is extremely high, and it has many advantages as a skylight device for daylighting, and has great practical value.
