[Means for solving the problems] A fastening surface is formed at a position higher than the ground surface, and a waterproof sheet is laid over the entire surface of the wild material. At this time, the joint between the adjacent waterproof sheet and the waterproof sheet is stopped. It is the base of the composition that it always overlaps on the wearing surface. As a method of constructing the fastening surface at a position higher than the ground surface, fixing a piece of wood to be a stand on the field material,
Alternatively, a method of fixing the light weight shaped steel may be considered. In addition, as another method, by placing a metal rafter on the purlin and dropping a field material having a thickness lower than the height of the metal rafter between the metal rafters, it is stopped at a position higher than the ground. The attachment surface (that is, the top surface of the metal barrel in this case serves as the attachment surface) can be configured. As described above, there are various methods for forming the fastening surface at a position higher than the ground surface.

[0009] A horizontal thatched roofing material is further laid on the roofing material, and the horizontal thatched roofing material has a heat insulating material attached to the back surface of the surface material which is the surface of the roof. The surface material has an eaves side engaging part and a ridge side engaging part, and the left and right ends are provided with joint parts, or the joint member is formed as a separate member and You can use it to connect. Since the present invention does not refer to the structure for connecting the roofing roofing members to each other, the method of connection will not be specifically stated.

The bottom surface of the heat insulating material attached to the back surface of the surface material is provided with a cutout portion having a size that completely covers the above-mentioned fastening surface.

The side-roofing roofing material having such a structure is covered with the cutout portion on the fastening surface, and the roofing material is laid on the base material having the above-mentioned construction, and the fastener is directly attached to the ridge of the side-roofing roofing material. And fix it on the fastening surface, or attach a hanging piece to the side of the thatched roofing material ridge and hit a fixing tool on the fixing surface of the hanging piece to fix it on the fixing surface. In this way, the fastening device for fixing the horizontal roofing material is hit on the fastening surface.

Flows on lower field material without staying in.

[0013]

Embodiments of the present invention will be described with reference to FIGS. Although FIG. 1 shows an example of the structure of the base, the base 2 is mounted on the base material 1. Since the upper surface of the table 2 serves as a fastening surface 21 for stopping the fastening tool for fixing the roofing roofing material, the table 2 is provided so as to match the interval for fastening the fastening tool.

The waterproof sheet 3 is laid over it,
The joints between the adjacent waterproof sheets 3 and the waterproof sheets 3 overlap each other on the fastening surface 21. If the overlapping portions are wide as shown in FIG. 1 and the ends of both waterproof sheets 3 exceed the fastening surface 21, the waterproof property is further enhanced.

FIGS. 2 and 3 are views for explaining the thatched roof material 4, in which a heat insulating material 6 is attached to the back surface of the surface material 5 which is the front surface. The surface material 5 is provided with a locking portion 52 on the eaves side and an engaging portion 51 on the ridge side. A fastening portion 55 for hitting a fastening tool is provided further on the ridge side of the engaging portion 51. The fastener 8 refers to a fastener used for construction, such as a nail or a screw that does not require a pilot hole (a screw that can perform three steps of drilling a hole, tapping, and fastening in a single process). The fastening portion 55 may be inclined slightly downward toward the ridge, or the edge thereof may be folded back upward. Also,
The edge of the locking portion 52 may be folded back downward.

On the bottom surface of the heat insulating material 6 attached to the back surface of the surface material 5, there is provided a notch portion 61 having a size that completely covers the fastening surface 21. Two examples will be shown as examples of providing the cutout portion 61. The first
The embodiment is shown in FIGS. 4 to 7, and the second embodiment is shown in FIGS. 4 and 8 are end views taken along the line AA of FIG. Next, these examples will be described.

First, the first embodiment will be described with reference to FIGS. 4 to 7. In this embodiment, as shown in FIG.
Is an embodiment in the case of being arranged near the left end in the figure of the thatched roofing material 4. The base 2 is located slightly to the right of the center of the upper thatched roofing material 4. Therefore, the cutout portion 61 of the heat insulating material 6 is provided near the left end of the thatched roof material 4 and slightly to the right of the center thereof, as shown in FIG.
When this heat insulating material 6 is attached to the back surface of the surface material 5 and the result is as shown in FIG. 4, and it is roofed on the base having the configuration of FIG. 1, it becomes as shown in FIG.

As shown in FIG. 5, a notch 6 is formed on the base 2.
1 is completely covered and the cutout portion 61 is provided in a large size, so that a gap 7 is formed between the cutout portion 61 and the waterproof sheet 3 which is placed on the base 2. The gap 7 serves as a ventilation groove, and also serves as a drain groove when the rainwater flows on the waterproof sheet 3 when the rainwater enters due to strong wind and rain. In order to make the rainwater flow more smoothly in this case, a taper portion 62 is provided on the ridge side of the heat insulating material 6 as shown in FIG. If the convex portion 63 and the concave portion 64 are provided at intervals of about 20 mm as in the conventional technique shown in FIG. 15, the heat insulating performance is deteriorated, but in the present embodiment, the cutout portion 61 and the cutout portion 61 are formed. Since the space between the portions 61 is wide, the heat insulating performance is not deteriorated, and since the notch portion 61 is provided in a large size, it also functions as water passage and ventilation. However, in the present invention, there is a possibility that rainwater may accumulate on the ridge side of the heat insulating material 6 between the cutout portions 61 and 61, so that the tapered portion 62 is provided in order to discharge the rainwater more smoothly. Of. This configuration has never been shown in the prior art.

Next, a second embodiment will be described with reference to FIGS. In this embodiment, as shown in FIG. 11, the table 2 is arranged at the center and left and right ends of the roofing roofing material 4 in the figure. Therefore, the notch 6 of the heat insulating material 6
As shown in FIG. 10, one is provided at the center of the thatched roofing material 4, and the left and right ends are provided with a width of half each.
When this heat insulating material 6 is attached to the back surface of the surface material 5 and the result is as shown in FIG. 8, and when it is roofed on the base having the structure of FIG. 1, it becomes as shown in FIG.

As in the first embodiment, as shown in FIG.
The notch 61 is completely covered on the upper part, and a large gap 7 is provided between the waterproof sheet 3 on the base 2 and the notch 61. The gap 7 serves as a ventilation groove, and also serves as a drain groove when the rainwater flows on the waterproof sheet 3 when the rainwater enters due to strong wind and rain.
Again, a taper portion 62 is provided on the ridge side of the heat insulating material 6 as shown in FIG. 10 so that the rainwater can flow more smoothly.

FIG. 3 shows an example in which the fastening member 8 is directly driven into the fastening portion 55 of the thatched roofing material 4, but there is a method shown in FIG. 12 as an example of using a suspender. The engaging portion 51 of this example is U-shaped in the horizontal direction, and the suspension 9 is hooked there. The fixing surface 91 of the suspension is fixed on the fixing surface 21 of the base 2 by the fixing tool 8. The shape of the engaging portion 51 is merely an example, and the engaging portion 51 and the suspension 9 having any shape may be used.
However, the fastening tool 8 that is struck by the fixed surface 91 of the suspension is fixed on the fastening surface 21. As another example, the ridge side of the heat insulating material 6 of the thatched roof material 4 is made to project beyond the surface material 5, and the fixing surface 91 of the suspender is placed thereon, and the heat insulating material 6 and the fastening member 8 are used for fastening. There is also a method as shown in FIG.

[0022]

The waterproof structure for a thatched roof according to the present invention has the structure as described above, and the fastening surface is formed at a position higher than the ground, and the lateral roof is attached to the fastening surface. Since the fasteners for fixing the material are struck, the infiltrating rainwater flows onto the lower field material without staying near the holes in the fasteners. Therefore, even when a storm such as a typhoon occurs, rainwater is prevented from entering the inside through the holes of the fasteners that fasten the roofing roofing material.

Further, since the heat insulating material attached to the back surface of the surface material of the thatched roof material is provided with the cutout portion having a size enough to completely cover the fixing surface of the base material,
The waterproof structure disclosed in JP-A-6-33554 can be used for a thatched roof. As described above,
The technique of using the waterproof structure shown in Japanese Patent Publication No. 33554 on a thatched roof is clarified.

Further, as in the prior art shown in FIG. 15, when the convex portions 63 and the concave portions 64 are provided at intervals of about 20 mm, there are many notched portions (that is, the concave portions 64), so that the heat insulation performance is improved. However, in this embodiment, since the gap between the cutout portions is wide, the heat insulation performance is better. And this notch part also fulfills the function of water flow and ventilation.
