DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof tile used for roofing a building such as a house.

[0002]

2. Description of the Related Art Conventionally, a roof tile used for roofing a building is made of metal having an overall shape of a substantially rectangular flat plate, and has a locking ridge protruding to the surface side along a ridge side edge. Some have a receiving groove formed by recessing the back side. In this type of roof tile, when roofing on a roof board, the accommodation groove is fitted from above to the locking ridge of the other roof tile located on the one eaves side in the roof flow direction On the back side of the joint with other roof tiles adjacent to the roof tile in the direction perpendicular to the roof flow direction, water that penetrates into the back side from the same joint is roofed in the roof flow direction eaves side Generally, a drainer for draining water is interposed.

[0003]

By the way, the drainer is an important member for draining moisture that enters from between the roof tiles arranged in a direction perpendicular to the direction of the roof flow to the outside. Was packed separately from the roof tiles and transported to the site, workers sometimes forgot to insert the drainer when sequentially roofing each roof tile. Sometimes occurred.

On the other hand, the locking ridges of each roof tile not only serve to connect with the roof tile on one ridge side, but also have a role of damming rainwater that tends to enter upward from below in the direction of roof flow. However, once rainwater rides on the locking ridge due to strong wind and rain, etc., the entered rainwater will not be discharged downward due to the presence of the locking ridge, and will stay in the lap portion of the roof tile. However, it sometimes penetrated into the building from the nailed portion of the roof tile and caused rain leakage.

The present invention has been made in view of the above-mentioned circumstances, and it is necessary to prevent an operator from forgetting to insert a drainer, or to prevent rainwater from staying in a lap portion of a roof tile, thereby making the roof of a building waterproof. The purpose is to improve.

[0006]

In order to achieve the above object,
The present invention has taken the following technical measures. In other words, the invention according to claim 1 has a roof having a locking ridge 5 protruding to the front side along the ridge side edge and a locking portion 9 protruding to the back side along the eaves side edge. A roof tile, which is connected to a locking ridge 5 of another roof tile located on one side of the roof in the roof flow direction so as to lock the locking portion 9 from above, and is orthogonal to the roof flow direction. In the roof tile, a draining joiner 12 is provided on a back surface side of a joint portion 13 with another roof tile that is adjacent in the direction, and drains water that enters the back surface side from the joint portion 13 downward in the roof flow direction. The draining joiner 12 is detachably provided at a position where the connection between the ridge 5 and the engaging portion 9 can be prevented.

According to the second aspect of the present invention, a locking ridge 5 protruding to the front side is provided along the ridge side edge, and a hook 9 protruding to the back side is provided along the eaves side edge. A roof tile that is connected to a locking ridge (5) of another roof tile that is disposed on one side of the roof in the roof flow direction such that the hook 9 is hooked from above. A roof tile in which a draining joiner 12 is provided on a back surface side of a joining portion 13 with another roof tile adjacent to the roof tile in a direction orthogonal to the flow direction, and drains water that enters the back surface side from the joining portion 13 downward in the roof flow direction. At the same time, the water 19 flowing along the ridge side of the locking ridge 5 is drained by the drainer joiner 12.
Located on the ridge side of the locking ridge 5
A drainage portion 18 formed by cutting out both ends of the flowing water portion 8 is provided at an end on the ridge side.

[0008]

According to the first aspect of the present invention, the hooking portion 9 of the roof tile 1 cannot be connected to the locking ridge 5 of another roof tile 1 unless the draining joiner 12 is removed from the roof tile 1. ,
Therefore, there is no need to forget to insert the drainer 12 when the roof tile 1 is constructed. In the invention according to claim 2, the locking ridge 5
Since the water 19 on the ridge side falls into the draining joiner 12 through the drainage part 18, rainwater does not stay on the ridge side of the locking ridge 5.

[0009]

An embodiment of the present invention will be described below in detail with reference to the drawings. 1 to 7, reference numeral 1 denotes a metal roof tile employed in this embodiment. The roof tile 1 includes an aluminum alloy tile body 2 formed in a thin rectangular plate shape, and a heat insulating material 3 made of a foamed resin or the like adhered to almost the entire back surface of the tile body 2. 3 on the back side
A large number of ventilation grooves 4 extending in the short side direction are formed.

On the ridge side edge of the tile main body 2, that is, the edge facing the ridge side of the roof after construction, a locking ridge 5 projecting toward the surface side of the tile main body 2 is provided in the longitudinal direction of the tile main body 2. The locking ridge 5 is oriented so that the tip is directed toward the center in the short side direction of the tile body 2. The drainage ridge 6 swelling on the surface side of the roof tile body 2 is further from the ridge side edge of the locking ridge 5.
Are provided in parallel with the locking ridges 5, and the ridge side edge of the tile main body 2 is bent to the surface side to form a folded portion 7, whereby the locking ridge 5 and the folded portion 7 are formed. A running water section 8 is formed between them.

On the other hand, at the edge of the roof of the tile main body 2, that is, at the edge of the roof facing the roof of the roof after construction, the locking ridge 5 is provided.
A hooking portion 9 which is hooked from above is bent toward the back side. Further, a step portion 10 extends in the longitudinal direction at the eaves end side end and the back surface side of the heat insulating material 3.
An accommodation groove 11 is formed by 10 and the hook 9 of the tile body 2.

Reference numeral 12 denotes a drainer, which is interposed on the back side of the joint 13 of each roof tile 1 adjacent to each other in a direction orthogonal to the roof flow direction, as shown in FIGS. This is for draining the water that has entered the side to the roof eaves side in the roof flow direction. As shown in FIG. 5, the drainer joiner 12 is made of a strip-shaped metal plate 14 longer than the short side of the roof tile 1. The both sides in the width direction and the upper edge of the metal plate 14 are formed on the surface side. The water-stop portion 15 is formed by bending, and the hook portion 16 to the locking ridge 5 is formed by bending the lower edge toward the back side. Further, the draining joiner 12 has three draining ridges 17 formed by bulging the metal plate 14 toward the surface side, and the draining ridges 17 are parallel to each other and extend in the longitudinal direction of the metal plate 14. Has been established.

In this embodiment, as shown in FIG. 3 and FIG. 4, the drainer 12 is temporarily fixed to the accommodation groove 11 of the roof tile 1 by an adhesive or forced insertion. That is, each roof tile 1 is prepared so that the draining joiner 12 can be detached into the accommodation groove 11 before the construction, and to the locking ridge 5 of the other roof tile 1 unless the draining joiner 12 is removed from the accommodation groove 11. The hook 9 is not hooked, thereby preventing the user from forgetting to insert the drainer 12 when the roof tile 1 is tiled.

Further, since the draining joiner 12 is accommodated in the accommodation groove 11, as shown in FIG. 6, even if each roof tile 1 is overlapped with the draining joiner 12, it does not become bulky.
The luggage for packing 1 can be made compact. In the present embodiment, as shown in FIG.
At both ends of the flowing water portion 8, drainage portions 18 formed by cutting out the both end portions are formed. Therefore, as shown in FIG. 7 (b), when the adjacent roof tiles 1 are overlapped at the joint portion 13, the running water portions 8 of both the roof tiles 1 are cut off by the drainage portions 18. As a result, the water 19 flowing in the flowing water portion 8 is received by the draining joiner 12 on the back side of the joint portion 13, and is drained downward by the draining joiner 12 in the roof flow direction.

FIGS. 1 and 2 show examples of the construction of a building roof using the roof tile 1 and the draining joiner 12 described above. In the figure, reference numeral 20 denotes a base plate as a roof base material, which is supported by rafters 21 fixed to the lower surface thereof, and a waterproof sheet (asphalt roofing) 22 is laid on the upper surface. Each roof tile 1 is provided on the waterproof sheet 22 with a locking ridge 5 of another roof tile 1 having a hook 9 previously installed.
The roofs are sequentially roofed toward the ridge side.

At this time, in the present embodiment, first, as shown in FIG. 1 (b), the draining joiner 12 provided in the accommodation groove 11 of each roof tile 1 is removed, and the hook 16 is already installed. Hook on the locking ridge 5 of the roof tile 1
Is set. Then, as shown in FIG. 1 (a), the joints 13 of the roof tiles 1 adjacent to each other on the left and right sides are received from below by a drainer joiner 12, and the two roof tiles 1 are roof tiles on one side of the eaves.
After connecting the roof tile 1, the roof tile 1 is fixed to the base plate 20 by driving a sealing nail 23 into the running water section 8.

Therefore, even if the roof tile 1 is to be installed without removing the drain tile joiner 12, the locking part 9 cannot be connected to the locking ridge 5 of another roof tile 1. Forgetting to insert the joiner 12 can be reliably prevented. In addition, as shown in FIG.
Is connected so that the hook 16 is hooked from above onto the locking ridge 5 on the eaves side, so that the joint of the roof tile 1 is
Moisture 24 received by the drainer joiner 12 from the drain 13 and the drainage section 18 is formed by the hook 16 of the joiner 12 and the hook of the roof tile 1.
It is drained to the outside between 9 and.

Although one embodiment of the present invention has been described above, the present invention is not limited to this. In other words, the mounting position of the draining joiner 12 with respect to the roof tile 1 may be in any position as long as the connection between the locking ridge 5 and the hooking portion 9 of the roof tile 1 can be prevented. It may be temporarily fixed in a state of contact with the stop ridge 5.

Further, the drainage portion 18 may be of any type as long as it allows water 19 flowing in the flowing water portion 8, that is, along the ridge side of the locking ridge 5 to fall to the back side. FIG.
As shown in the figure, the ridge side end of the joint 13 is cut out in a semicircular or U-shape, and a round hole 25 or a square hole 26 is formed in the flowing water portion 8 in the joined state of the roof tile 1, The drainage section 18 can also be configured.

[0020]

As described above, according to the first aspect of the present invention, the roof tile cannot be connected to another roof tile unless the drainer is removed, so that the drainer cannot be forgotten to be inserted. One of the causes of the leak can be reliably prevented, and thus the waterproofness of the building roof can be improved.

According to the second aspect of the present invention, since the water flowing along the locking ridge drops from the drainage portion provided at the ridge end of the joint portion to the draining joiner, the lap portion of the roof tile is provided. That is, rainwater does not stay on the ridge side of the locking ridge, and the waterproofness of the building roof can be improved.
