Description

[Detailed description of the invention] [Technical field] This invention relates to a drainage structure for a lighting window installation device.

[Background technology]

FIG. 4 shows an example of a lighting window installation device for tile roofing. This lighting window installation device includes a mounting base frame 2 installed in accordance with a roof opening 1,
It has a lower frame 3 attached to the upper side thereof, and a window frame 5 provided with a window glass 4 for daylighting. The lower frame 3 is provided with a drain frame 6 that integrally extends below the water. Tiles 7 are arranged at regular intervals below the mounting frame 2.
In this case, the water-side drainage sheet 8 is provided so that rainwater, leaves, etc. flowing from the water surface side can smoothly flow to the water surface side. One end of the draining sheet 8 in the inclined direction is sandwiched between the mounting base frame 2 and the lower frame 3, and the other end in the inclined direction rests on the upper surface of the tile 7.

However, in the conventional draining structure shown in the figure, a recess 9 was formed at a location corresponding to the front side of the tile 7 on the draining sheet 8;
Rainwater, etc., accumulated in the basin and could not be drained smoothly to the bottom.

[Purpose of invention]

In view of the above-mentioned circumstances, the object of this invention is to provide a drainage structure for a lighting window installation device that allows rainwater, etc. to flow smoothly under water.

[Disclosure of invention]

In order to achieve the above object, the drainage structure of the lighting window installation device according to this invention is such that a window frame is provided in an opening formed in a sloping roof, and a window frame and a roof provided below the water are provided. In the drainage structure of the lighting window installation device, a drainage sheet on the underwater side is provided between the roofing materials, and the end of the drainage sheet on the underwater side rests on the roofing material. The part of the sheet on the front side of the above-mentioned part of the sheet is lifted up by a spacing member inserted under the sheet, and extends straight at an angle such that it gradually becomes lower towards the horizontal or underwater side. .

This invention will be explained in detail below with reference to drawings showing embodiments thereof.

FIG. 1 shows, in cross section, an example of the drainage structure of the lighting window installation device according to this invention.
A roof opening 1 is formed in a reinforcing frame 40 formed using rafters 30 on a main building 20.
A mounting base frame 2, which is rectangular when viewed from above, is attached to this roof opening 1.
A lower frame 3 is attached to the upper side of the frame 3 so as to be fitted from above. A window frame 5 having a daylighting window glass 4 is attached to the lower frame 3 so as to be openable and closable. A waterproof sheet (not shown) is laid on the top surface of the field board 10, and this waterproof sheet covers a portion provided around the outer periphery of the mounting base frame 2 to form a rectangular shape when viewed from above, and a portion of the base frame 2 that is rectangular when viewed from above.
It has a part that stands up along the . A draining frame 6 having an L-shaped cross section and projecting parallel to the roof board 10 is integrally formed on the outer periphery of the lower frame 3 so as to have a rectangular shape when viewed from above. On the above-water side of this draining frame 6, an above-water side draining sheet 13 equipped with snow splitters 13a is laid. Between the right and left sides of the drain frame 6 and the mounting base frame 2, there is a drain drain 14.
are sandwiched together and laid so as to extend on both sides as shown in Figure 2. The tiles 7 are installed on the above water (ridge) side and below the water (eaves) side of the mounting base frame 2.
They are arranged at intervals on both the left and right sides. As shown in FIG. 2, this tile 7 is a pseudo tile in which the wavy shape of Japanese roof tiles is utilized and the wavy shape is integrally formed in a series. Between the tiles 7 placed on the water side and the mounting base frame 2, there is a spacer 15 as shown in FIG.
A lower water drainage sheet 8 is provided. In other words, the draining sheet 8 is made of a thin, flexible sheet such as a lead plate or a copper plate, and is formed into an oblong shape, and has a slightly narrowed and rising insertion protrusion at one end. A piece 8a is formed. The spacing member 15 is made of a foamed resin material such as expanded polystyrene and is formed as a triangular block. This supporting member 15
covers the entire width of the draining sheet 8 so that the top side of the triangle is on the side of the insertion protrusion 8a, and the thick side opposite to the top side is on the side opposite to the insertion protrusion 8a. It is glued like this. As shown in FIG. 1, the draining sheet 8 with the spacer 15 is configured such that the insertion protrusion 8a is inserted between the lower frame 3 and the mounting base frame 2, and the rear end of the sheet is placed on the tile 7. The spacer 15 is set so as to rest on it, and the spacer 15 is set so as to fit into the front of the roof tile 7 on the water side. This results in
The part 8 on the front side of the part on which the draining sheet 8 rests
As shown in FIG. 1, it is lifted from the roof board 10 and extends straight at an angle that is gradually and gently inclined toward the water side with respect to the horizontal line.
As shown in FIG. 2, the draining sheet 8 is corrugated so as to follow the corrugation of the tile 7 below the water, and the spacing material 15 is also corrugated. Both left and right ends of the draining sheet 8 are pressed down by left and right roof tiles 7.

As mentioned above, the front part 8b on which the water-side draining sheet 8 rests is gradually raised toward the tile 7 side by the spacer 15 on the lower side, and is gradually inclined, so that rainwater is removed. etc., are now smoothly flowed toward the eaves along this front portion 8b, and there is no longer any fear of them accumulating in the recesses as was the case in the past. Moreover, draining sheet 8
Even if it is made of a soft material like lead plate,
Since it is reliably received by the spacing member 15, the front portion 8b can be kept in a constant inclined state forever.

In addition, although the said space|interval holding material 15 was designed to span the whole width of the draining sheet 8, it may be divided|segmented. Although the lighting window is an openable type, it may be a closed type. In that case,
The lower frame 3 and the window frame 5 may be separate types or may be integrated.

[Effect of idea]

As we have seen above, with this idea, the front side of the part of the draining sheet that rests on the roofing material is
It is lifted up by the spacing material inserted below and extends horizontally or straight at an angle that gradually becomes lower below the water, so rainwater does not accumulate on the water side and the eaves can be smoothly installed. It began to flow to the side.
