Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a daylighting window structure suitable for a thatched roof.

[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. 27 or 28, a rafter 3 is arranged on the base material 2 laid on the purlin 1 so as to intersect with the purlin 1, and a large number of them are arranged in the direction of the eaves. The structure of a daylighting window structure suitable for a thatched roof having a structure in which the roofing materials 5 are connected to each other, and a supporting frame 7 is provided in a rectangular opening 6 formed between adjacent purlins 1 as shown in the figure. Fit,
It has a structure in which the glass 9 in which the frame parts 11 to 13 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, as shown in FIG. 24, for example, a roof material 5a having a wider width than the other roof material 5 must be provided on the eaves side to adjust the dimensions.

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, especially between the frame portions 11 to 13 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]

[Purpose] The present invention has been made in view of such problems, and an object thereof is to provide a daylighting window structure which does not impair the appearance of a thatched roof, is easy to construct, and has high work efficiency.

Another object of the present invention is to reliably prevent water leakage into the room due to dew condensation on the lighting window surface.

[0011]

In order to achieve the above object, in the first aspect of the present invention, a side-roof type in which the adjacent eave side and ridge side are connected to each other on the upper surface of the base material laid on the main roof In a horizontal thatched roofing roof plate, a supporting frame member fitted into an opening formed through the roofing plate and the base material is provided, and the supporting frame member is provided with a flange portion around the upper edge thereof. A guide groove is formed on the side of the flange portion so as to face the roof surface along the direction of the eaves, while the roof plate placed on the upper surface of the roof plate is adjacent to the eaves direction. A water stop surface door material having a shape that compensates for a step portion that occurs between and forms a supporting edge portion along the roof slope at a position near the upper surface of the step portion is disposed at a side of the opening. Then, the guide groove of the support frame material is fitted on the support edge portion of the water stop surface door material to mount the support frame material on the roof plate. A light-transmitting plate, which is supported and at least elastic side waterproof members are attached to the ridge side and the side, is fitted to the flange portion of the support frame member, and the rain-pressing member for covering the upper surface of the elastic waterproof member is provided on the flange. The transparent plate is fixed by being attached to the portion.

As a second invention, in the above-mentioned daylighting window structure, a waterproof substrate made of a plate-like material is laid as an underlaying material on the upper surface of the base material, and an opening into which a supporting frame material is fitted is provided on the waterproof substrate. A rising portion having a predetermined height is provided so as to surround the portion.

As a third invention, in the above-mentioned daylighting window structure, the rain-pressing member attached to the ridge-side flange portion of the support frame member is a ridge-side end portion of the roof plate adjacent to the ridge side as a base end portion. The upper surface of the roof plate is formed so as to cover the flange portion.

As a fourth aspect of the invention, in the above-mentioned daylighting window structure, the support frame member is provided with a support step portion on an inner surface thereof which is located a predetermined distance below a light transmitting plate surface mounted on the flange portion of the support frame member. A dew condensation receiving plate member having a shape matching the inner shape of the support frame member is mounted on the step.

As a fifth invention, the eaves side end of the daylighting plate is
It is placed on the eaves side flange part of the support frame material via the elastic waterproof member, and the eaves side rain control member is placed under the eaves side end of the lighting plate and from the eaves side end part of the flange part to the roof plate. It was formed so as to adhere to.

As a sixth aspect of the invention, a part of the eaves side of the support step portion is extended in the eaves direction, and a dew condensation water storage portion is formed between the extension portion and the transparent plate.

[0017]

According to the first aspect of the invention, since the translucent plate of the daylighting window is located slightly above the roof surface via the flange portion provided at the upper edge of the supporting frame member, the daylighting plate is illuminated. The translucent part of the window does not interfere with the surrounding roof plate, which eliminates the need to use a special size roof plate, which simplifies the construction work and preserves the aesthetics of the thatched roof. At the same time, problems regarding strength and rigidity are avoided.

The transparent plate is sealed by an elastic waterproof member attached to the periphery thereof by the flange portion of the supporting frame member and the rain-pressing member covering the flange portion, and moreover, a concentrated inflow of rainwater from the side occurs. Since it does not have a special sealant, it ensures reliable watertightness.

According to the second aspect of the invention, even if rainwater enters the back surface of the roof plate, the rainwater is formed into a gap between the rainwater and the supporting frame material by the rising portion formed around the opening of the base material. Since the intrusion is prevented, the water leakage to the indoor side is surely prevented.

According to the third aspect of the present invention, even if a step is formed between the ridge-side portion of the supporting frame member and the roof plate adjacent thereto due to the positional relationship with the roof plate, the rain-preventing member provided on the ridge side prevents Appearance is adjusted by covering the steps, and the flow of rainwater from the ridge is smoothly guided to the lighting window, so that an appropriate cleaning effect can be obtained.

According to the fourth aspect of the invention, since a heat insulating space is formed between the light transmitting plate located above the support frame member and the dew condensation receiving plate member located below, the light transmitting caused by the temperature difference between the inside and outside of the room. Generation of dew condensation on the lower surface of the plate is suppressed, and even if dew condensation occurs, it is guided below the support frame member by the receiving plate member, so that drip indoors is avoided.

According to the fifth aspect of the invention, since the eaves-side end of the daylighting plate is not covered by the eaves-side rain-pressing member, the effect of cleaning the daylighting surface by rainwater becomes remarkable, and the eaves-side end does not become dirty. .

According to the sixth aspect of the present invention, even if a large amount of dew condensation water is generated, it is temporarily stored in the storage portion formed on the eaves side, so that the dew condensation receiving plate member and the supporting step portion move toward the indoor side. Condensed water is prevented from leaking.

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 lighting 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.

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 (a scraping plate), which not only serves as a joint for the roof plate 15 but also at the joint portion. 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, the water stop surface door material 36 is fixed to the upper surface of the end portion of each roof plate 15 located on the side of the opening 21 in the vicinity of the opening 21 with screws or the like. As shown in FIG. 20, the water stop surface door material 36 is formed by bending a metal plate material so that the eaves side end portion 36a has a substantially wedge shape narrower than the ridge side end portion 36b, and each roof plate 15 The size in the longitudinal direction is set so that one pad corresponds to one. The upper and lower flange portions 36c, 36d formed by bending are set symmetrically for the right and left sides as shown in FIG. 20, and the flange portions 36c, 36d are respectively arranged in the direction of the opening 21. Arrange so that 36d faces.

As shown in FIG. 10, the eaves side end 36a and the ridge side end 36b are joined to each other in the eaves ridge direction in a state where they are arranged on the roof sill 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 and two rows of supporting edges 37 parallel to each other are formed 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 support step portion 22b formed on the inner peripheral surface of the support 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 figure, 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 structure for housing the transparent plate 24 at the edge of the eaves may be another structure as described later (see FIG. 24).

The rain retaining member 26 located at the eaves side edge of the flange portion 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 translucent plate 24, as shown in FIG. 1 or 17, a large rain guard member 28 having substantially the same width as 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, the draining plate 40 is attached to the upper surface of the roof plate 15 adjacent to the ridge side of the support 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, and if rainwater invades the roof back 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 manner, 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).

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, an engaging portion 28e having a shape overlapping the ridge-side engaging portion 15b of the lower roof plate 15 is formed at the eave-side edge portion.

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-pressing 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
Reliable waterproofness is exhibited together with the elastic waterproof member 25 fitted around the.

Incidentally, as shown in FIG. 18, a connecting member 42 is provided between the connecting flange portion 28d extending on both sides of the rain-preventing member 28 and the end portion of the roof plate 15 adjacent thereto by screws or the like. By mounting and further covering with a cover 43 having the same sectional shape as the roof plate 15 so as to cover the connecting member 42, a completed state as shown in FIG. 19 is obtained.

According to the daylighting window structure for a thatched roof constructed as described above, the following actions and effects are exhibited.

That is, since the translucent plate 24 is positioned 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. The above problem is avoided.

Further, the transparent plate 24 is provided with an elastic waterproof member 25 attached to the periphery thereof, and the flange portion 23 of the support frame member 22 and the rain-preventing members 26, 27, 28 covering the flange portion 23.
Because it is sealed and the rainwater does not flow in intensively from the side, reliable watertight performance is achieved without the need for special sealant processing.

Further, even if rainwater enters the back surface of the roof plate 15, the rainwater is separated from the support frame member 22 by the rising portion 13b of the waterproof substrate 13 formed around the opening 21 of the base material 12. Since it is prevented from invading into the gap, it is possible to surely prevent water leakage to the indoor side.

The step or gap between the edge of the support frame member 22 (flange portion 23) on the ridge side and the roof plate 15 adjacent to the ridge is controlled by the rain-preventing member 28 provided on the ridge side. Appearance is adjusted by covering the stepped portion and the flow of rainwater from the ridge side is smoothly guided to the transparent plate 24, so that an appropriate cleaning effect is secured.

Further, since a heat insulating space is formed between the light transmitting plate 24 located above the support frame member 22 and the dew condensation receiving plate member 30 located below, the light transmitting plate 24 caused by the temperature difference between the inside and outside of the room. The occurrence of dew condensation on the lower surface is suppressed, and even if dew condensation occurs, it is generated by the support plate member 30 at the support frame member 22.

As described above, according to the present invention, the supporting frame member which fits into the opening formed through the roof plate and the base member is provided, and the supporting frame member is provided around the upper edge of the supporting frame member. A flange portion is provided, and one of the flange portions that is located on the side is formed with a guide groove facing the roof surface along the eaves direction, while it is placed on the upper surface of the roof plate in the eaves direction. A water stop door material having a shape that compensates for a step between adjacent roof materials and that forms a supporting edge along the roof slope near the upper surface of the step is located on the side of the opening. And the guide groove of the supporting frame member is fitted on the supporting edge portion of the water stop surface door member to support the supporting frame member on the roof plate, thereby providing the lighting window and the surrounding roof member. Since we have tried to avoid interference with the roof, it is no longer necessary to prepare a roofing material with special dimensions and construct a roof. It is possible to keep the specific orderly appearance next 葺 roof along with the construction work I can be facilitated. Further, since it is not necessary to use a wide roofing material, it is possible to avoid the problem that the strength and rigidity are reduced.

Further, a translucent plate having elastic waterproof members mounted on at least the ridge side and the side is fitted on the flange portion of the support frame member,
Since the rain-pressing member that covers the upper surface of the elastic waterproof member is attached to the flange portion to fix the light-transmitting plate so as to achieve sealing, it is possible to prevent rainwater from concentrating from the side. And reliable watertight performance can be obtained. Further, in this case, since a special sealant treatment by a specialist is unnecessary, it is possible to perform the construction only by the roofer, so that the construction efficiency is improved.

On the other hand, in the above-mentioned daylighting window structure, a waterproof substrate made of a plate material is laid on the upper surface of the base material, and a rising portion of a predetermined height is provided so as to surround the opening portion into which the support frame material is fitted. When formed on the substrate, even if rainwater enters the back surface of the roof plate, this rainwater enters the gap between the support frame material and the rising part formed around the opening of the base material. Since the water leakage is prevented, the effect of reliably preventing water leakage to the indoor side is added.

Similarly, in the above-mentioned daylighting window structure, a rain-pressing member to be attached to the ridge-side flange of the supporting frame member is
When the ridge-side end of the roof plate adjacent to the ridge side is formed as a base end so as to cover the upper surface of the roof plate so as to reach the flange portion, the support frame material is formed depending on the positional relationship with the roof plate. Even if there is a step between the ridge-side part of the building and the roof plate adjacent to it, the rain-preventing member provided on the ridge side covers the step and the appearance is adjusted, and the flow of rainwater from the ridge side Since it is smoothly guided to the daylighting window, the effect of obtaining an appropriate cleaning effect is added.

Further, in the above-mentioned daylighting window structure,
A dew condensation receiving plate member having a support step portion on the inner surface which is located a predetermined distance below the light transmitting plate surface mounted on the flange portion of the support frame member, and has a shape matching the inner shape of the support frame member on the support step portion. When the is attached, a heat insulating space is formed between the upper transparent plate and the lower condensation receiving plate member, so that the condensation on the lower surface of the transparent plate caused by the temperature difference between the inside and outside Generation of dew condensation is suppressed, and even if dew condensation occurs, it is guided below the support frame member by the receiving plate member, so that the effect of preventing the dew condensation water from dripping indoors is added. Further, in the structure provided with such a dew condensation receiving plate member, the eave side portion of the supporting step portion is extended in the eaves direction to secure the dew condensation water storage portion, so that even if a large amount of dew condensation water is generated, Since the water is temporarily stored in the section, it is possible to prevent the condensed water from leaking to the room side through the gap between the dew condensation receiving plate member and the supporting step portion, and to further enhance the waterproof property.

The eaves-side end of the daylighting plate is placed on the eaves-side flange of the support frame through the elastic waterproof member, and the eaves-side rain-pressing member is attached to the eaves-side end of the daylighting plate. Since it was made to adhere on the roof plate from above the eaves side end of the flange under the subordinates, dust etc. will not adhere to the eaves side end of the daylighting plate,
Good lighting can be obtained.
