DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a roof base material such as a purlin or beam made of a shaped steel, 2 denotes a field board made of a wool cement board or a hard wood chip cement board or the like disposed on the roof base material 1, 3 denotes a field board A waterproof material such as asphalt roofing or rubber asphalt waterproof sheet laid on 2 is a roof plate of a vertical roof. The roof plate 4 is made of a flat metal plate made of a colored painted steel plate or the like, and is covered with a heat insulating material 5 such as polyethylene foam to prevent rain noise and dew condensation. At both left and right ends of the roof plate 4, a downward plate portion 6 in which the edge of the roof plate 4 is bent downward at a substantially right angle, and a locked portion 7 in which the lower end of the downward plate portion 6 is folded inward.
Then, the lower part of the locked portion 7 is bent outward to form a gutter portion 9 having a V-shaped cross section. The gutter 9 has a watertight packing 10
Adhesively fixed.

At the time of roofing such a roofing plate 4, a through-hook 11 for connecting the ends of adjacent roofing plates 4 is provided.
Cap 1 to be inserted between the ends of adjacent shingles 4
2 are prepared. The cap 12 is a long object having a top plate portion 14 and a pair of side plate portions 15 bent downward from both left and right ends of the top plate portion 14, and is bent using the same material as the roof plate 4. The width of the top plate portion 14 is set to be substantially the same as the interval between the downwardly directed plate portions 6 and 6 of the adjacent roof plate 4, and the side plate portion 15 is elastically deformable. It is formed in a shape that follows the outer surface of the locked portion 7, and is bent in the form of a middle bend having a step portion 17 that engages with a corner portion 16 where the downward plate portion 6 and the locked portion 7 intersect.

The through hook 11 is formed by bending a metal plate and forming the gutter 1.
8 and locking metal fittings 19 integrally formed on both sides of the gutter 18 along the longitudinal direction thereof. Gutter 18 is flat bottom wall 2
0 and side wall portions 2 erected from both left and right ends of the bottom wall portion 20.
1, and a folded portion 22 is horizontally provided inward at the upper end of the side wall portion 21. Each of the left and right locking fittings 19 has a fixed plate portion 23, and the first upright plate portion 24 stands upright from one side end of the fixed plate portion 23, and the upper end of the first upright plate portion 24 is removed. The inclined part 25 is formed continuously in the downward direction, and the lower end of the inclined part 25 is
2, and a corner portion where the inclined portion 25 and the folded portion 22 intersect is referred to as a locking portion 26. On the other hand, the second upright plate portion 27 is erected upward from the other end of the fixed plate portion 21 to a height lower than the first upright plate portion 24, and the receiving piece 28 is removed from the upper end of the second upright plate portion 27. Install horizontally outward.

The hanging member 11 thus constructed is placed at a predetermined position on the base plate 2 in the direction of the eaves ridge, and the fixed plate 23
The fixing member 29 such as a self-drilling screw is passed through the base plate 2 to be fixed to the roof base material 1. Next, a back-up material 30 made of polystyrene foam or the like to assist the heat insulation, sound insulation and strength of the roof plate 4, particularly heat insulation, is placed on the receiving piece 28 of the through-hanger 11, and It is laid so as to form an air layer 31 thereon. The air layer 31 also exerts a heat insulating effect, reduces the influence of the outside air on the room together with the heat insulating material 5 and the backup material 30, and hardly causes dew condensation.

Next, the inside of the locked portion 7 of the one roof plate 4 is hooked and engaged with the lower end of one of the locking portions 26 of the looper 11. Similarly, the inside of the locked portion 7 of the other roof plate 4 is engaged with the lower end of the other locking portion 26.
By engaging the inside of the locked portion 7 of the roof plate 4 with the lower end of the locking portion 26, even if a large negative pressure acts on the roof plate 4, the roof plate 4 can counteract the negative pressure and exhibit negative pressure resistance.

Finally, the cap 12 is fitted between the downwardly facing plate portions 6, 6 of the adjacent roof plates 4, 4 from above by utilizing the elastic deformation of the side plate portion 15. This cap 1
By the fitting of 2, the gap between the downwardly facing plate portions 6, 6 of the adjacent roof plates 4, 4 is closed. Cap 12 is step 1
7 is engaged with the downwardly facing plate portion 6 and the corner portion 16 of the locked portion 7 so that the locked portion 7 of the roof plate 4 is locked even when a negative pressure is applied. The engaged state with the lower end of the portion 26 can be reliably maintained. The cap 12 can be prevented from receiving the wind pressure directly by placing the top plate portion 14 so as to be slightly lower than the upper surface of the roof plate 4, and imparting a three-dimensional effect of unevenness to the upper surface of the roof plate 4 to achieve a design effect. Demonstrate.

Since the watertight packing 10 is placed in the gutter 9 of the roof plate 4, the lower end of the side plate 15 is tightly engaged with the watertight packing 10 as the cap 12 is fitted.
Accordingly, even when rainwater enters between the overlapping surfaces of the cap 12 and the roof panel 4, it is possible to effectively stop the water with the waterproof packing 10. Therefore, waterproof packing 1
Zero prevents rainwater intrusion to the utmost, and even if it does,
Also, even when the rainwater overflows from the gutter section 9, the rainwater can be discharged to the eaves by the gutter 18, and the inflow of the rainwater into the room can be effectively prevented. Since the through hook 11 formed integrally with the gutter 18 is used as the locking metal 19, the number of members and the number of construction steps can be significantly reduced.

FIGS. 2 and 3 show another embodiment. In this embodiment, a pair of left and right locking metal fittings 19 is formed by extruding aluminum separately from the gutter 18 and cutting the extruded aluminum material into short lengths. It is different from the through hook 11. The latch 1
Reference numeral 9 denotes a band-shaped fixed plate portion 23 that is continuous to the left and right, a pair of first upright plate portions 24 that are erected from two intermediate positions of the fixed plate portion 23 so as to face each other, and an upper end of each first upright plate portion 24 Horizontal plate portions 24a in which the horizontal plate portions 24
and a second upright plate portion 27 which is provided outside the left and right first upright plate portions 24 on the fixed plate portion 23. Second upright plate 2
7 has an upper end and a receiving piece 28 horizontally connected outward.

The metal fitting 19 is passed through the gutter 18 between the left and right first upright plate portions 24, 24 and placed on the field base plate 2. The first upright plate portion 24 and the second upright plate portion The fixing plate portion 23 between the fixing members 27 is fixed to the roof base material 1 via the base plate 2 with a stopper 29 such as a self-drilling screw. At this time, since the left and right ends of the fixed plate portion 23 project further outward than the second upright plate portion 27 to form the auxiliary seat piece 23a, the contact area of the locking metal 19 with the field plate 2 is reduced by the auxiliary seat portion. Piece 23a
Therefore, it can be mounted and fixed on the base plate 2 stably. The gutter 18 is fixed by frictional engagement with the locking metal 19, but if this alone is used, there is a risk of sliding movement toward the eaves when the roof slope is large, so the end of the gutter 18 on the ridge side is fixed with bolts or the like. I do. Other configurations, for example, the backup material 30, the roof plate 4, the watertight packing 10, and the cap 1
2 is the same as in the above embodiment.

[0018]

According to the present invention, since the water-stop packing is interposed between the lower end of the side plate portion of the cap and the inside of the gutter portion of the roof plate which are not directly affected by wind pressure, the cap and the roof plate can be connected to each other. The function of stopping rainwater that intrudes in between can be effectively exhibited, and the waterproofness of the waterproof packing can be significantly improved. Rainwater blocked by the waterproof packing can be discharged to the eaves at the gutter.

Since the backup material is placed on the receiving piece of the locking metal, an air layer having a heat insulating function can be easily formed between the backup material and the base plate, and the thickness of the backup material can be reduced. However, it is possible to reduce the deterioration of the heat insulation performance and prevent the occurrence of dew condensation. Such an air layer can also be used for wiring and piping space.
