DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof tile and a roof of a building using the roof tile.

[0002]

2. Description of the Related Art Roof tiles to be laid on the roof of a building are roughly classified into flat and wavy tiles. Of these, the wavy roof tiles are curved in the width direction toward the surface. As a result, a ridge extending in the vertical direction and flowing water portions (valleys) located on both sides of the ridge are integrally provided. Conventionally, in the case of this type of wavy roof tile, both edges in the vertical direction are generally formed linearly in plan view.

On the other hand, in a particularly windy area such as near a coast or along a mountain, in order to prevent the roof tiles from turning up due to a strong wind, the roof tiles may be subjected to special windproof construction to construct the roof of the building. . As a wind-resistant fixing structure for such a roof tile, the eaves end of another roof tile located on one ridge side is hooked with a clip attached to the roof tile using a fixing nail for fixing the roof tile. There is a technology that prevents the roof tiles from turning up by stopping them.
No. 90846).

[0004]

However, in a conventional wavy roof tile, both longitudinal edges are formed linearly in a plan view. Therefore, such a wavy roof tile is simply employed in the windproof fixing structure. In such a case, the following inconvenience occurs. That is, for example, in FIG. 5, when the wrap length L ₂ between the roof tiles 1 and 1 is long, the separation distance from the hook portion 12 of the clip 10 to the fixing nail 5 also becomes long,
The fixing force of the clip 10 decreases, and the wind resistance of the roof deteriorates.

On the other hand, if the wrap length L ₂ between the roof tiles 1 and 1 is shortened in order to maintain the fixing force of the clip 10,
There is a high possibility that rainwater flowing through the water flow section 3 of the roof tiles 1 and 1 will enter the back side of the roof tiles 1 and 1, thereby reducing the waterproof performance of the roof.
In view of such circumstances, an object of the present invention is to provide a roof tile capable of simultaneously improving the water resistance and the wind resistance of the roof, and a roof using the roof tile.

[0006]

In order to achieve the above object,
The present invention has taken the following technical measures. That is, according to the first aspect of the present invention, the middle part in the width direction is curved toward the surface side, so that the ridge part 2 extending in the vertical direction and the flowing water parts 3 located on both sides of the ridge part 2 are formed. In the roof tile in which an insertion hole 4 for a fixing nail 5 or the like is opened at the top of the roof 2 and from one side in the vertical direction, the other vertical edge of the mountain 2 is
3, characterized in that it is formed closer to one side than the other side edge in the same direction.

Further, according to the second aspect of the present invention, each roof tile is fixed on the base plate 7 by fixing means such as fixing nails 5 so that the roof tile is moved from the eaves side of the base plate 7 toward the ridge side. In a roof of a building that is laid up so as to be sequentially wrapped, the roof tile includes the roof tile 1 according to claim 1,
The roof tiles 1 are arranged with the other side edges facing the eaves, respectively, and the roof tiles 1 are located on the crests 2 of the roof tiles 1 on the eaves side of the roof tiles 1 located one eaves side from the roof tiles 1. The clip 10 for hooking the end is fixed by fixing means such as the fixing nail 5 or the like.

[0008]

[Function] Clip 10 attached to mountain 2 of roof tile 1
The roof tile 1 is located one ridge side of the roof tile 1 and the roof edge of the mountain part 2 of the roof tile 1 is hung to prevent the roof tile 1 from being turned up by a strong wind. Since the other side edge of the mountain section 2 (eave side edge) is formed on one side of the other side edge of the flowing water section 3, as shown in FIG. the while wrap length L ₁ of the flowing water portion 3 is sufficiently secured, it is possible to shorten as much as possible the distance between the clip 10 and the locking nail 5 and the like.

[0009]

An embodiment of the present invention will be described below with reference to the drawings. 1 to 4, reference numeral 1 denotes a roof tile used in this embodiment. The roof tile 1 is made of a ceramic or slate-based material, and is curved in the width direction (the left-right direction in FIG. 3A) toward the surface side.
Four ridges 2 extending in the vertical direction and a valley 3 located between the ridges 2 are integrally provided, and are formed in a wave shape having a substantially sinusoidal shape in a front view.

Reference numeral 4 denotes an insertion hole for a fixing nail 5, which in this embodiment is the top of the first and third peaks 2 from the left and
It is opened from the upper side in the vertical direction. The lower edge of the roof tile 1 in the vertical direction is, as shown in FIGS.
2 is formed in a wave shape in plan view so that the lower edge of the valley 3 is turned over by a certain distance (D) above the lower edge of the valley 3. Notches 6 are provided in the upper left and lower right corners of the roof tile 1 respectively.

FIG. 2 shows a roof of a building using the roof tile 1. In the figure, reference numeral 7 denotes a base plate as a roof base material, which is supported by rafters 8 fixed to the lower surface side,
A waterproof sheet 9 is laid on the upper surface. Each roof tile 1
With the lower edge facing the eaves front side, the mountain 2 comrades are roofed so that the mountain 2 comrades wrap sequentially from the eaves side of the field base plate 7 toward the ridge side, and are inserted into the insertion holes 4 from above. Each is fixed to the field plate 7 side by a fixing nail 5.

Reference numeral 10 denotes a clip for hooking the edge of the roof tile 1 on the eaves tip side to prevent the roof tile 1 from being turned up by a strong wind. The clip 10 is formed by bending one end of a strip-shaped metal plate into a U-shape, and
And a hook portion 12 are integrally provided, and a nail hole is provided in the center of the substrate portion 11. When the clip 10 is fixed to each roof tile 1 with the fixing nail 5, the fixing nail 5
The hook 2 of the clip 10 is attached to the top of the crest 2 so that the tip of the crest 2 of the next roof tile 1 is hooked.

In order to construct the roof of a building using the roof tile 1 and the clip 10 according to the above configuration, as shown in FIG. 1, when the roof tile 1 is fixed by the fixing nail 5, the same fixing nail 5 is used. After the clip 10 is attached to the top of the mountain 2 in advance, the tip of the mountain 2 of the next roof tile 1 is inserted into the hook 12 of the clip 10, and thereafter the roof tile 1 is similarly fixed by the fixing nail 5. The fixing of the roof tile 1 and the attachment of the clip 10 are performed at the same time, and the roof tile 1 may be roofed toward the ridge side.

At this time, according to the present embodiment, the lower edge of the roof tile 1 is corrugated so that the lower edge of the peak 2 is
4 is formed above the lower edge of FIG.
As shown in, together can exert a strong fixing force by short as possible a span length of the clip 10, sufficient wrap length L ₁ is secured in the valleys 3 rainwater flowing down, the roof Does not impair the waterproofness.

FIG. 5 shows a conventional wavy roof tile.
1 shows a comparative example in which the windproof construction of this example was performed using FIG. As is apparent from a comparison between FIG. 5 and FIG. 4, since the lower edge of the conventional roof tile 1 was straight in a plan view,
The distance between the locking nail 5 and clip 10 in proportion to the wrap length L ₂ between the roof tiles 1,1 becomes longer, therefore, to that fixing force of roof tile 1 according to the clip 10 than the case of the present embodiment is inferior Has become.

According to the present embodiment, since the fixing of the roof tile 1 and the fixing of the windproof clip 10 can be simultaneously performed by the fixing nails 5, the work for windproofing the roof tile 1 can be greatly reduced. There is also an advantage. The present invention is not limited to the above embodiment. That is, the front shape of the roof tile 1 is not limited to the wavy shape, but, for example, as shown in FIG. 6, only the peak portion 2 has a curved shape and the valley portion 3 has a flat shape. The point is that the shape may be such that the middle part in the width direction is curved toward the surface side to form the mountain part 2 extending in the longitudinal direction and the flowing water part on both sides of the mountain part.

The fixing means for the roof tile 1 includes fixing nails 5.
In addition, other set screws and the like can be used.

[0018]

According to the present invention, when the roof tile 1 is subjected to wind resistance using the clip 10, the distance between the clip 10 and the fixing nail 5 is made as large as possible while ensuring a sufficient wrap length of the flowing water portion 3. Since the length can be shortened, the fixing force of the clip 10 can be maximized while sufficiently maintaining the water resistance of the roof, and thus both the water resistance and the wind resistance of the roof can be simultaneously improved. .

According to the second aspect of the present invention, since the roof tile 1 and the clip 10 are simultaneously fixed by the fixing nails 5 and the like, in addition to the above-described effects, the construction time can be reduced.
