〔Example〕

An embodiment of this invention will be described below with reference to FIGS. 2 to 4.

The hangers 1 are arranged in parallel on the surface of the roof base material A at predetermined intervals, and include a mounting piece 1a that is fixed along the surface of the roof base material A with screws 2;
A support piece 1b protruding from one end of the mounting piece 1a at a predetermined height, and a connecting piece 1c extending approximately parallel to the roof base material A from the upper end of the support piece 1b. It is formed in an approximately Z-shape. A recess 3 that opens toward the lower part of the roof slope is formed by the surface of the roof base material A and the support piece 1b and the connection piece 1c of the hanger 1.In this recess 3, the side surface of the support piece 1b is formed. A holding piece 4 is provided protrudingly provided on the holder, and a locking piece 5 is provided protrudingly provided on the lower surface of the distal end of the connecting piece 1c.

Both shingle plates 6 and 7 are placed above and below the roof slope.
Among them, at the upper end of the lower roofing plate 6, there is a connecting groove 9 in which an engaging part 8 that engages with the locking part 5 of the hanger 1 opens downward.
It is formed into a substantially U-shaped cross section. As shown in FIG. 4, this engaging portion 8 is fitted into the recessed portion 3 from below by pushing the engaging portion 8 into the recessed portion 3. The piece 8a is formed in an inclined shape that gradually widens toward the tip with respect to the plate surface of the roofing board 6, and is also formed to be elastically deformable. When the engagement part 8 is pushed into the recess 3 by a predetermined amount, the tip of the engagement piece 8a engages with the engagement piece 5 of the hanger 1 to stop the roofing board 6 from falling, and The proximal end of the piece 8a comes into contact with the holding piece 4 of the hanger 1 to prevent the roofing board 6 from lifting up.

On the other hand, at the lower end of the upper roofing plate 7 is a connecting portion 1 whose tip is inserted into the connecting groove 9 of the lower roofing plate 6.
0 is formed in a folded shape. This connecting part 10
is formed into a corrugated plate shape in cross section with first and second troughs 10a, 10b and peaks 10c, 10d, thereby connecting the connecting portion 10 and the lower roofing plate 6.
First and second drainage spaces 11 and 12 are defined between the plate surface and the plate surface to prevent rainwater from accumulating. Further, the first valley portion 10a located on the base side of the connecting portion 10 faces the plate surface of the lower roofing board 6 with a predetermined gap therebetween. A drainage space 11 opens downward to the roof slope. Further, the second valley portion 10b is in contact with the surface of the lower roofing board 6, thereby closing the second drainage space 12. Note that the first trough portion 10a also serves as a fitting portion into which one end 13a of a joint material 13 for connecting another roofing board in the lateral direction of the roofing board 7 is fitted. In addition, roof base material A
A waterproof sheet B made of turfelt or the like is laid on the surface of the roof, and the space created between the sheet B and each of the roofing boards 6 and 7 has fire resistance and heat insulation properties, and is protected against the load of workers, etc. An interior material C is interposed to prevent the plates 6 and 7 from being dented.

In the above configuration, the connecting portion 1 of the upper shingle 7
The first trough 10a formed at 0 is the lower roofing board 6.
Since the upper roofing board 7 faces the board surface with a predetermined gap, the rainwater on the upper roofing board 7 flows down toward the lower roofing board 6 as shown by the arrow P in FIG.
is prevented from entering the drainage space 11. Moreover, when rainwater is blown toward the first drainage space 11 and the rainwater enters the first drainage space 11, the first drainage space 11 opens toward the lower part of the roof slope. Therefore, this first drainage space 11
Rainwater will not accumulate in the area. Even if rainwater were to enter the second drainage space 12 across the first drainage space 11, the second drainage space 12 would prevent the candy water from entering further inside.
Furthermore, since the amount of rainwater entering the second drainage space 12 is reduced by the first drainage space 11, rainwater is prevented from accumulating in the second drainage space 12. Furthermore, as shown in FIG.
It is also possible to form a drainage notch 14 in b to actively drain rainwater that has entered the second drainage space 12.

In the above embodiment, both the first and second drainage spaces 11 and 12 were formed between the connecting portion 10 of the upper roofing plate 7 and the plate surface of the lower roofing plate 6.
The drainage space may be divided into two or more sections, and
Even if there is only one drainage space, it is effective in preventing accumulation of rainwater.

[Effects of the invention] As described above, according to this invention, the drainage space formed between the connection part of the lower end of the upper roofing board and the surface of the lower roofing board prevents the accumulation of rainwater. Therefore, it is possible to prevent corrosion of the connection portion between the upper and lower roofing boards caused by accumulation of rainwater, and it is possible to improve durability.

Moreover, the engaging portion of the lower shingle and the connecting portion of the upper shingle are connected and held in the recess formed by the roof base material, the supporting piece of the hanger, and the connecting piece, and the above-mentioned By supporting the lower surface of the upper shingle by the connecting piece of the hanger, when a load is applied to the upper surface of the upper shingle, the load is received by the supporting piece and the connecting piece of the hanger. I can do it.
In this way, the connecting portion between the upper and lower roofing boards can be protected, and the problem of the connecting portion being crushed can be actively prevented.

Furthermore, within the recess, a retaining piece formed on the support piece of the hanger presses down the retaining piece of the retaining part on the lower shingle, and a retaining piece formed on the connecting piece of the hanger is pressed. By locking the tip of the locking piece, it is possible to actively prevent the lower roofing board from lifting up, and also to prevent the lower roofing board from falling. As a result, the connection between the locking part of the lower shingle and the connecting part of the upper shingle can be firmly maintained, and it is possible to actively prevent the shingle from coming off against the roof base material. It's also effective.
