Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a daylighting window frame device suitable for a thatched roof and its construction method.

[0002]

2. Description of the Related Art Generally, a conventional daylighting window (a skylight) on a roof tends to spoil the aesthetics of the roof because the window frame is raised from the roof surface, and the effect of washing by rainwater flowing on the roof surface cannot be expected. Therefore, there is a problem that dirt easily adheres to the window glass.

As a solution to the problems of the prior art, the applicant of the present invention discloses a window structure in which a window glass surface is provided at a position lower than the roof surface, as disclosed in Japanese Patent Laid-Open No. 165853. Is proposed.

As shown in FIG. 25 or FIG. 26, the rafters 3 are arranged on the base material 2 laid on the main building 1 so as to intersect the main building 1, and a large number of them are arranged in the eaves direction. Is a window that is suitable for a thatched roof having a structure in which roofing materials 5 are connected to each other, and a support frame 7 is fitted into a rectangular opening 6 formed between adjacent purlins 1 as shown in the figure. It has a structure in which the glass 9 in which the frame parts 111 to 113 are fitted is attached to the front, rear, left and right edges from above.

In this case, since the glass 9 is provided at a position lower than the upper surface of each roof member 5 as shown in the figure, the entire roof has a planar appearance. Further, since the glass 9 is washed by the rapid flow of rainwater that flows down from above the roof at the time of raining, the adhesion of dirt is reduced and the good lighting effect is maintained for a long period of time.

[0006]

By the way, according to such a daylighting window structure, since the glass 9 is adhered from above the support frame 7, the glass 9 extends laterally from the support frame 7 toward the eaves. Since a part of the glass 9 is projected and the glass 9 is located lower than the surrounding roof material 5, the glass 9 is particularly located on the eaves side or the roof side of the window where the roof material 5 should be located.
May interfere with each other, and as a result, FIG.
As shown in FIG. 6 , for example, it becomes necessary to adjust the size by providing a roof material 5a wider than the other roof material 5 on the eaves side.

A backup material 4 made of wood wool plate or the like is provided on the lower surface of each roofing material 5, 5a to secure strength and rigidity. However, since the roofing material 5a is wide and has a large flat portion, The rigidity of itself is low and it may cause wavy deformation due to thermal expansion or strong wind, and the orderly appearance peculiar to a thatched roof is impaired at this part.

Further, since the glass 9 is located at a lower position than the surrounding roof surface and rain water tends to concentrate, particularly between the frames 111 to 113 and the glass 9 and the surrounding roof structure. It is necessary to apply a sealant to the product to ensure waterproofness, but since it is necessary to request a specialized contractor for such work, it is necessary to adjust the work schedule with the roof contractor. This tends to cause the work efficiency during construction to deteriorate.

[0009]

[PROBLEMS] The present invention has been made in view of such problems, and provides a daylighting window frame device and a construction method thereof, which do not impair the external appearance of a thatched roof, can be easily constructed and can improve work efficiency.

To support.

Next, the details of each of the above parts will be described with reference to FIGS.
It will be described based on. 3 to 19 are perspective views showing the construction procedure of the daylighting window structure shown in FIGS. 1 and 2, but these are seen from the eaves direction and the ridge direction for convenience of explanation. Since things are mixed with each other, arrow E is used in the figure to indicate the eaves direction.

To form the daylighting window shown in FIGS. 1 and 2, first, as shown in FIG. 3, the opening 21 is formed in the base material 12. The base material 12 is laid on the purlin 11 so as to connect a number of long materials in the purlin direction, and at this time, the bolts 17 fixed to the purlin 11 are arranged so as to penetrate the respective joint portions. In the figure, 14 is a metal rafter 14 in a temporarily fixed state.
Is shown.

Next, as shown in FIG. 4, a wood mouth concealing member 32 formed by bending a metal plate into a U-shape is attached to the opening edges of four sides of the base material 12 forming the opening 21 by adhesion or the like. Then, as shown in FIG. 5, a waterproof substrate 13 made of a stainless steel or other non-corrosive metal plate or a metal plate material coated with a water resistant coating is laid on the base material 12.

The waterproof substrate 13 has a plurality of protrusions 13a in the eaves ridge direction for covering the joint portion of the base material 12 and is in contact with the purlin direction and the eaves ridge direction so as to cover the entire upper surface of the base material 12. To set up. At this time, the eaves-side end of the waterproof board 13 located on the ridge side is connected so as to overlap the ridge-side end of the waterproof board 13 located on the eaves side, and rainwater that has invaded the roof back surface When flowing to the side, the upper surface of the base material 12 is prevented from entering through the gap between the joints.

Of the waterproof substrate 13, the one covering the upper surface of the opening 21 is provided with a notched shape in accordance with the opening 21 and a part thereof is surrounded so as to surround the opening 21 as shown in the drawing. By bending upward, the rising portion 13b having a predetermined height is formed. In this case, the rising portions 13b are formed on both sides of the opening 21 and the edge portions on the eaves side, and the raised corner portions are sealed with waterproof putty or the like.

After arranging the backup material 16 between the suspensions 14a and connecting the roof plate 15 from the eaves side to the ridge side, the horizontal thatched roof is roofed as shown in FIGS. In this case, it goes without saying that the roof plate 15 located on the side of the opening 21 is adjusted in size so as not to cover the opening 21.

In FIGS. 8 to 9, reference numeral 35 denotes a joint for connecting the roof plates 15 adjacent to each other in the purlin direction to each other. It also functions as a gutter to drain the invading rainwater toward the eaves.

After roofing the roof plate 15 in this manner,
As shown in FIG. 10, a water stop surface door material 36 as a modified example of the support portion 50, which will be described later, is provided on the upper surface of the end portion of each roof plate 15 located on the side of the opening portion 21 in the vicinity of the opening portion 21. Secure with screws. This water stop surface door material 36 is shown in FIG.
As shown in FIG. 3, the metal plate material is bent so that the eaves side end portion 36a is formed into a substantially wedge shape thinner than the ridge side end portion 36b, and each roof plate 15 has a corresponding one pad in the longitudinal direction. The dimensions are set. The upper and lower flanges 36c and 36d formed by bending are shown in FIG.
As shown in FIG. 0, the right side and the left side are set symmetrically, and the flanges 36c,
Arrange so that 36d faces. 24. For details of the support member 50 in which the water stop surface door material 36 is formed long, see FIG.
Will be described later.

As shown in FIG. 10, the eaves-side end 36a and the ridge-side end 36b are connected to each other in the eaves ridge direction when arranged on the roof slab 15, and the steps between the roof slabs 15 are joined to each other. It becomes a mode to supplement the part, and each upper flange part 3
6c forms a series of linear support edges 37 (see FIGS. 10-11) slightly higher than the roof plate 15 and along the roof slope. In addition, the lower flange portion 3 seated on the roof surface
If necessary, putty or the like is used to seal the gap between 6d and the roof plate 15. The water stop surface door material 36 can be fixed to the roof plate 15 by adhesion, and in that case, it is not always necessary to provide the sealing.

In this way, the water stop surface door material 36 is arranged to form two rows of supporting edges 37 parallel to each other on both sides of the opening 21, and then the opening is formed as shown in FIGS. 21
The fitting frame portion 22a of the support frame member 22 is fitted to the above from above, the guide groove 23a formed in the flange portions 23 on both sides is fitted to the support edge portion 37, and the water stop surface door member 36 is used to support the frame. The material 22 is supported on the roof plate 15. That is, the water stop surface door member 36 is preliminarily positioned so as to correspond to the distance between the two guide grooves 23a of the support frame member 22, so that the support frame member 22 can be securely placed on the support edge portion 37. It is designed so that it can be placed.

Next, the dew condensation receiving plate member 30 is placed on the supporting step portion 22b formed on the inner peripheral surface of the supporting frame member 22, and the elastic waterproof member 25 is fitted around the transparent plate (in this case, (Granulated glass) 24 to the flange portion 23 around the upper edge of the support frame member 22
(See FIG. 13), and the eaves side edge portions and both edge portions are covered with rain suppression members 26 and 27 from the upper surface (FIG. 14).
reference). In this embodiment, as the supporting step portion 22b of the supporting frame member 22, the side surface and the ridge side surface are formed by attaching members having an L-shaped cross section as described above, but the eaves side surface is shown in FIG. As shown in, the eaves side end face portion 22c of the support frame member 22 is formed by bending the eaves side end face portion 22c from the middle to the outside. As a result, the eave-side portion of the support step portion 22b is greatly expanded forward, and the storage portion 22d for temporarily storing the condensed water is provided in the upper portion (see FIG. 1).

As shown in FIG. 21, the rain-preventing member 27 has a flange portion 27b extending outward from a lower edge portion of a rising portion 27a along a side surface of the flange portion 23, and a pressing portion extending inward from the upper edge portion. 27c are respectively formed, and the pressing portion 27c is elastically waterproofed between the bottom surface of the flange portion 23 and the pressing portion 27c by tightening the pressing portion 27c from its upper surface to the flange portion 23 (bottom portion of the guide groove 23a) with a screw 38. The member 25 is sandwiched to hold the transparent plate 24. In this case, the screw 38 penetrates through the flange portion 23, and the upper flange portion 36 of the water stop surface door material 36.
As a result, the rain-pressing member 27 is fixed to the flange portion 23, and at the same time, the flange portion 23 is fastened together with the water stop surface door material 36 to fix the support frame material 22 to the roof surface. .

As shown in the drawing, a folded-back portion 27d is formed on the inner edge of the pressing portion 27c so as to be positioned slightly inside the inner peripheral portion of the elastic waterproof member 25, thereby enhancing the waterproof performance. ing. A sealant may be applied to the inner portion of the folded portion 27d and the joint portion of the elastic waterproof member 25 and the transparent plate 24.
Since this portion has a simple cross-sectional shape, it is possible to easily perform the sealant treatment without requiring a special technique, and thereby the waterproofness can be further ensured.

The rain retaining member 26 located at the edge of the eaves side of the flange 23 also has substantially the same sectional shape as the side rain retaining member 27. However, while the rain-preventing member 26 has a shape in which both ends are open, the rain-preventing member 27 has a cover portion 27e formed at its eave-side end so as to cover both end portions of the rain-preventing member 26 from the eaves side. This improves waterproofness and appearance (see FIG. 14).

On the other hand, with respect to the ridge-side edges of the flange portion 23 and the transparent plate 24, as shown in FIG. 1 or 17, a large rain guard member 28 having a width substantially the same as that of the roof plate 15 is provided.
Is provided. In the case of this embodiment, this is the roof plate 15 where the ridge-side edge of the flange 23 is adjacent.
Since it is located at a position slightly higher than the eaves side end portion 15a of the eaves side, this step difference is eliminated and the flow of rainwater from the eaves side is surely guided to the upper surface of the translucent plate 24 and the appearance is adjusted. It was done.

When attaching the rain-pressing member 28, first, as shown in FIG. 15, a draining plate 40 is attached to the upper surface of the roof plate 15 adjacent to the ridge side of the supporting frame member 22. This draining plate 40 is formed by bending an oblong material having an L-shaped cross-section into an obtuse angle so as to be convex in the ridge direction at the center, and as shown in FIG. The roof plate 15 by tightening through
Install on top. Then, a sealant 41 is applied to the joint portion between the flange portion 40a and the roof plate 15 for waterproofing.

Both ends of the draining plate 40 are dimensioned so as to reach the outer portions of the left and right rain retaining members 27, so that if rainwater invades the roof rear side and flows down from above. Also, this can be guided to both sides of the draining plate 40 and can be released from the side of the rain guard plate 27 to the eaves side. This prevents rainwater from concentrating on the joint between the ridge-side flange 23 of the support frame member 22 and the elastic waterproof member 25 and causing water leakage to the inside.

After the draining plate 40 is attached in this way, the backup material 29 is attached to the portion of the roof plate 15 on the ridge side of the draining plate 40 as shown in FIG. This backup material 29 is formed so that its planar shape corresponds to the portion of the roof plate 15 behind the draining board 40, and the eaves side portion having a height similar to that of the draining board 40 as a side shape. It has a wedge-shaped cross-sectional shape in which the thickness gradually decreases from the ridge to the ridge side (see Fig. 1). It has a wedge-shaped cross-sectional shape (see FIG. 1).

After the backup material 29 is attached on the roof plate 15, the rain-preventing member 28 is placed over the backup material 29.
To wear. As shown in FIG. 17, the rain-preventing member 28 has a pressing portion 28b having a cross-sectional shape similar to that of the rain-preventing member 27 formed at the eaves side edge of the inclined portion 28a that covers the upper surface of the roof plate 15. At the same time, a connecting flange portion 28d is formed laterally on the lateral edge portion via a wedge-shaped side surface portion 28c that fills a step between the lower roof plate 15 and the lateral edge portion. Similarly, as shown in FIG. 23, the edge on the ridge side is close to the rising portion of the ridge-side engaging portion 15b of the lower roof plate 15.
An engaging portion 28e having a similar shape is formed.

When mounting the rain-guard member 28, the engaging portion 28e is positioned so as to overlap the ridge-side engaging portion 15b of the roof plate 15, and the rain-preventing portion 28b is attached to the ridge-side of the support frame member 22. The elastic waterproof member 25 is put on the flange portion 23 from above, and the pressing portion 28b is fastened to the flange portion 23 via a fastener such as a screw. If necessary, the overlapping portion on the ridge side may be fixed by adhesion or putty.

FIG. 18 shows the rain-pressing member 28 in this way.
4 shows the state in which the attachment of the light-transmitting plate 24 has been completed.
Since it is securely held by the transparent plate 24
Real waterproofness is demonstrated.

A connecting member 42 is provided between the connecting flange portions 28d extending on both sides of the rain-preventing member 28 and the end portion of the roof plate 15 adjacent to the connecting flange portion 28d as shown in FIG. The cover 43 having the same sectional shape as the roof plate 15 is attached so as to cover the connecting member 42, and the completed state shown in FIG. 19 is obtained.

FIG. 24 is a perspective view of the support member 50. This support member 50 is made by bending a metal plate,
The water stop surface door material 36 is integrally formed so as to have the same shape as that of a plurality of water door surface door materials 36 connected to each other. The holding member 50 has a step shape 51 that is placed on the upper surface of the roof plate 15 in the lower part and compensates for a step portion that occurs between the roof plates 15 that are adjacent to each other in the eaves direction, and the slope of the roof plate 15 is in the upper part. It is formed so as to have a support edge portion 37 extending along. The support member 50 may be formed in advance according to the size of the opening 21, or may be formed in advance as a long product and cut and used on site. In addition, about the part common to the water stop surface door material 36,
The same reference numerals as those of the water stop surface door material 36 are given and the description thereof is omitted.

The procedure for joining the supporting frame member 22 to the supporting frame member 22 is performed in the same manner as the joining using the water stop surface door member 36, whereby the guide groove 23 and the supporting edge portion 37 of the supporting frame member 22 are joined. And are fitted tightly.

In the case where the daylighting window frame device according to the present invention is applied in this way to construct a horizontal roof, the following actions and effects are exhibited.

That is, since the translucent plate 24 is located slightly above the roof surface via the flange portion 23 provided at the upper edge of the support frame member 22, the translucent plate 24 is Since the part does not interfere with the surrounding roof plate 15 and this eliminates the need to use a roof material with a special size, the construction work is facilitated and the aesthetics peculiar to the thatched roof are maintained, while at the same time strength and rigidity are maintained.
