More specifically, the metal roofing material B has a long plate shape, and as shown in FIG. 1, a stepped decorative surface in which a substantially horizontal decorative surface 4, a back surface 5, and a tip of the decorative surface 4 are suspended downward. 6, the upper surface 7 projecting inward along the stepped decorative surface 6 and the decorative surface 4, the innermost piece 8 projecting downward from the tip of the upper surface 7, and the distal end of the innermost piece 8 projecting below the water A substantially U-shaped engagement groove 10 is formed from the inserted piece 9, the upper surface 7, the innermost piece 8, and the inserted piece 9, and an insertion gap 11 is formed between the stepped decorative surface 6 and the inserted piece 9. Thus, the male connecting portion 12 is obtained.
[0010]
Further, as shown in FIG. 1, a waterproof piece 13 formed by bending the tip of the decorative surface 4 upward at the water-side end of the decorative surface 4 and a fitting in which the tip of the waterproof piece 13 protrudes above the water is provided. The section 13a, the upper surface 14 with the tip of the fitting piece 13a protruding downward, the fixed piece 15 with the tip of the upper surface 14 protruding upward, and the upper surface 14 and the fixing surface 15 have a substantially U-shaped cross section. The female connecting portion 17 is formed by forming a fitting groove 16 that fits the formed insertion piece 9. Further, a locking piece 18 as shown in FIG. 3 (b) is formed at the end of the decorative surface 4, and the roofing material A is locked by engaging with the engaging piece 19 of the joiner D shown in FIG. 3 (a). Is fixed on the base α.
[0011]
1, the height of the stepped decorative surface 6 is t, the height of the fitting piece 13a is T, the distance between the stepped decorative surface 6 and the insertion piece 9 is h, and the width of the fitting piece 13a is H. Then, the relationship is t ≦ T and h> H. Further, t = T is effective for waterproofing because no gap is formed between the lower roofing material A and the upper roofing material A. In addition, about h = H + 5-10 mm is preferable.
[0012]
When the insertion gap 11 is inserted as shown in FIG. 2A to connect the roofing materials A together, the fitting piece 13a is inserted into the engagement groove 10 so that the stepped decorative surface 6 does not get in the way. It is formed so that it can be done.
[0013]
The stepped decorative surface 6 forms a step and gives a solid feeling to the roof, forms a space inside, and prevents the wind and rain from directly hitting the connecting portion of the roofing material A. By forming the gap between the connecting portion formed at the time of connection, the shape, and the tip portion of the stepped decorative surface 6 and the tip portion of the fitting piece 13a up and down, the waterproof property is improved. is there.
[0014]
The fitting piece 13a forms a fitting groove 16 having a U-shaped cross section by projecting the tip of the waterproof piece 13 to the water side, and by inserting the insertion piece 9 into the fitting groove 16, the roof material A is connected to each other.
