Horizontal portions 10d, 10d are successively formed in these fixed recesses 4a, 4b, and a tip airtight piece 5a is formed following one horizontal portion 10d. The other horizontal portion 10d is formed with a substantially inverted V-shaped tip holding portion 6b. A heat insulating material 7 such as polyethylene foam is adhered to the back surface of such a roof plate 3.
It is also possible to use only a folded sheet roof material which is formed by bending a metal plate and applying a paint finish without attaching a metal plate.

As shown in FIG. 1, the fixing recess 4a of one roof plate 3a is fitted to the connecting projection 2a of the fixing fitting 2 from the direction of arrow B by utilizing the elastic deformation of the roof plate 3a. Then, the fixing recess 4b of the other shingle 3b is fixed.
Is pressed onto the connecting projection 2b of the fixing fitting 2 from the external fitting and fixing direction A to be externally fitted and fixed. In such a case, the tip airtight piece 5a of the one roof plate 3a holds the substantially inverted V-shaped tip holding portion 6b of the other roof plate 3b, and thus the tip airtight piece holding the tip airtight piece 5a. As shown in FIG. 2, the holding portion 6b is caulked with a caulking jig J at appropriate intervals in the length direction, for example, at a pitch of 500 mm.
In FIG. 2, J ₁ indicates a swaged portion. Then, the cap 8 is connected at the connecting point of the two roof plates 3a, 3b.

Yes, avoiding the condensation. The tip piece 6c of the tip holding portion 6b, which is inclined obliquely downward, is inclined obliquely downward so as to be substantially along the external fitting fixing direction A for externally fixing the fixing recess 4b of the fixing fitting 2 obliquely from above. Then, the other roof plate 3b is pressed from the external fitting fixing direction a to be externally fixed to the fixture 2, and the substantially inverted V-shaped tip holding portion 6b is held by the tip airtight piece 5a of the one roof plate 3a. In order to hold the tip airtight piece 5a, it is easy to hold the tip airtight piece 5a with the substantially inverted V-shaped tip holding part 6b. It can be done in.

Further, the inclination angle α ₁ of the tip piece 6 c is equal to or smaller than the fixing angle α ₂ in the external fitting fixing direction A for externally fixing the roof panel 3 b to the fixing fitting 2. In the construction, the tip holding portion 6b does not hit the tip airtight piece 5a, so that the workability is not further hindered. Further, the distal end holding portion 6b is caulked at an interval in its length direction to clamp and fix the distal end airtight piece 5a, so that the distal end airtight piece 5a and the distal end holding portion 6b for holding the same are formed. This suppresses the formation of a gap between them, and further increases the airtightness. A cap 8 is externally fitted and fixed to such a connecting portion between the roof plates 3a and 3b.

FIGS. 4 and 6 show another embodiment.
As described above, the shape and shape of the fixing bracket 2 and the shape and shape of the cap 8 can be variously changed. 4 and 6 show a state before the caulking step. FIG. 7 shows still another embodiment, in which an oblique piece 20 is formed substantially in parallel with the tip piece 6c so as to extend below the tip airtight piece 5a of the one roof plate 3a. A diagonal piece 21 is formed substantially in parallel with the tip piece 6c so as to extend below the tip holding portion 6b of the other roof plate 3b. Thus, the oblique piece 20 and the oblique material piece 21 formed below the tip airtight piece 5a.
Thereby, the inclined passage 22 is formed, and it becomes easier to further suppress the hot air from flowing right above the vertical path. Thus, the occurrence of dew condensation due to the escape of hot air is further suppressed. Moreover, the oblique piece 20 and the oblique material piece 21 are formed substantially parallel to the tip piece 6c that is inclined obliquely downward, so that the workability in connecting the roof plates 3a and 3b is not reduced. In such a case, FIG.
The tip holding portion 6b holding the tip airtight piece 5a with the hand-held tool 23 as shown in (c) is partially closed flat and bent to the oblique piece 20 side while holding the tip airtight piece 5a. It is done. In such a case, the distal end holding portion 6b may be flattened in a flat folded shape over the entire length by the electric roll forming machine. As described above, the substantially inverted V-shaped tip holding portion 6b is deformed flat by holding the tip airtight piece 5a, and
A sufficient airtightness is obtained by the synergistic action with the bending to the zero side. Thus, the ventilation of the hot air is shut off to avoid dew condensation caused by the escape of the hot air.

FIG. 8 shows still another embodiment, and FIG.
As shown in the embodiment shown in FIG. 7, the tip holding portion 6b is caulked at intervals in the length direction of the jig J, and the tip airtight piece 5a is provided.

Thereafter, the distal end holding portion 6b is bent toward the oblique piece 20 to further improve the airtightness. 7 and 8
It goes without saying that the roof plates 3a and 3b in the embodiment of the present invention are connected via the fixing bracket 2 and are covered with the cap 8. Further, a heat insulating material 7 may be attached to the roof plates 3a and 3b.

[0019]

As described above, according to the present invention, one roof plate has a substantially inverted V-shape in which the tip airtight piece is erected at the tip further than the fixing recess, and the other roof plate holds the tip airtight piece. Is formed, so that the tip airtight piece of one of the shingles is held by the substantially inverted V-shaped tip holding portion of the other shingle, and the tip of the shingle is connected. There is no gap in the portion, the hot air escapes from the gap, the occurrence of dew condensation due to the temperature difference on the lower surface of the cap is suppressed, and the tip which inclines obliquely downward in the tip holding portion, while avoiding dripping of dew. Since the piece is inclined obliquely downward substantially along the external fitting fixing direction in which the fixing recess of the other roof panel is externally fixed to the connection projection of the fixing bracket from above, the other roof panel is removed. Pressing from the fitting and fixing direction, the outer fitting is fixed to the fixing bracket, and a substantially inverted V-shaped tip In order to hold the holding portion on the tip airtight piece of one roof plate, it is possible to avoid the tip holding section from hitting the tip airtight piece, and to hold the tip airtight piece with a substantially inverted V-shaped tip holding piece. There is an advantage that the construction can be easily performed, and the construction is not deteriorated due to the adoption of such a configuration.

Further, an oblique piece is formed substantially parallel to the tip piece so as to extend below the tip airtight piece, and a diagonal piece is formed substantially parallel to the tip piece so as to extend below the tip holding portion. An inclined passage is formed by the oblique piece and the oblique material piece formed below the airtight piece, and it is easier to further suppress the hot air from escaping just above the vertical path, and to prevent the occurrence of dew condensation due to the hot air escaping. There is an advantage that it can be further suppressed. In addition, since the oblique pieces and the oblique material pieces are substantially parallel to the tip pieces that are inclined obliquely downward, there is an advantage that the workability in connecting the roof shingles is not reduced.

Further, since the inclination angle of the tip piece is equal to or smaller than the fixing angle in the external fitting fixing direction in which the roof shingle is externally fixed to the fixing bracket, the tip holding portion is formed in the other roof shingle. There is an advantage that it does not hit the airtight piece and does not hinder the workability. Further, since the tip holding portion holding the tip airtight piece is closed flat and bent to the oblique side while holding the tip airtight piece, the substantially inverted V-shaped tip holding portion has a tip airtightness. The problem of dew condensation caused by the fact that the piece is sandwiched and deformed flat and the bend to the oblique side synergistically achieves sufficient airtightness, shuts off the ventilation of hot air, and allows hot air to escape. There is an advantage that it can avoid.

The substantially inverted V-shaped tip holding portion is caulked at an interval in its length direction to hold and fix the tip airtight piece. Therefore, the tip airtight piece and the tip holding the tip are sealed. There is an advantage that a gap can be suppressed from being formed between the holding portion and the airtightness.
