FIG. 1 shows the recessed structure of the roof according to the embodiment of the present invention. The roof 1 includes a covering board 2 and a plurality of roofing materials 3 provided on the covering board 2 . A recess 10 is present in the roof 1 . The two covering plates 2 and 2 form a certain angle with respect to the horizontal direction, and the ends of the two covering plates 2 are connected to each other to constitute the concave portion 11 of the covering plate 2 . The recessed part 10 of the roof 1 is formed in the place which comprises the recessed part 11 of the covering plate 2 . A groove 12 having a waterproof function is provided along the concave portion 11 . A plurality of hangers 13 are provided so as to extend from the groove 12 in a vertical direction with respect to the groove 12, and each hanger 13 is fastened to the covering plate 2 by nailing the nails 14 as the first fixing members, thereby The groove 12 is fixed to the concave portion 11 .

As shown in FIG. 2 , a plurality of roofing materials 3 have a rectangular shape, and are installed so as to overlap in the slope direction of the roof 1 and to face each other in a direction (horizontal direction) perpendicular to the slope direction. In the concave portion 10, a metal plate-shaped shielding member 4 is provided between the roofing materials 3 and 3 in the horizontal direction of the roofing material 3 for each layer. The cut surface 3a of the roof material 3 is exposed in the concave portion 10, and a gap 5 is formed between the cut surfaces 3a, 3a. The grooves 12 are exposed from the gaps 5 . That is, the gap 5 is hidden by providing the shielding member 4 , and the groove 12 is also hidden by the shielding member 4 .

As shown in FIGS. 3 and 4 , the shielding member 4 is a plate-shaped member bent so that the angle of the concave core 21 and the concave portion 11 (refer to FIG. 1 ) of the covering plate 2 becomes the same angle. The edge portion of the shielding member 4 connected to one end of the concave core 21 is bent so as to leave a space with the body of the shielding member 4. The two joint portions 22 are formed on the shielding member 21 in a manner of sandwiching the concave core 21. Component 4. This interval is equal to or larger than the thickness of the roofing material 3 (refer to FIG. 1 ), as long as it is an interval at which the roofing material 3 can be inserted into the joint portion 22 . The edge of the shielding member 4 connected to the end of the engaging portion 22 is folded on the same side as the side on which the edge constituting the engaging portion 22 is bent so as to be in contact with the body of the shielding member 4 to form a resistance. Etched edge portion 23 . The edge portion 24 of the shielding member 4 including the other end portion of the concave core 21 is cut into a triangular shape at both ends of the edge portion 24 , and notches 25 are formed at both ends of the edge portion 24 .

As shown in FIG. 1 , the shielding member 4 is fastened to the roofing material 3 in the recess 10 by inserting the roofing material 3 into the joint portion 22 from the edge portion 3b side of the roofing material 3 on the lower side in the slope direction of the roof 1 . Each layer in the horizontal direction is installed against the roofing material 3. As shown in FIG. 2 , the concave cores 21 of each shielding member 4 are arranged above the grooves 12 and along the grooves 12 . In each shielding member 4, there is a fixing region 26 which is a region extending to the opposite side of the concave core 21 than the hanger 13. As shown in FIG. The fixing region 26 is fastened and fixed to the roofing material 3 with the nails 15 as the second fixing member, whereby the shielding member 4 is firmly fixed to the roofing material 3 . Moreover, as shown in FIG. 1, the nail 15 penetrates the roof material 3, and penetrates into the covering board 2 as well. Thereby, the shielding member 4 is further firmly fixed as a constituent element of the recessed part 10 of the roof 1 . Furthermore, the overlapping portion of the roof material 3 and the shielding member 4 is filled with a known caulking material, whereby the shielding member 4 can be more firmly fixed. Further, the nails 15 are located on the opposite side of the concave core 21 than the hangers 13 , so that they will not penetrate into the grooves 12 , and thus will not have any influence on the waterproofness of the grooves 12 .

As shown in FIG. 2 , the anti-corrosion edge portion 23 extends parallel to the slope direction of the roof 1 . Thereby, the water system flowing down the upper surface of the roof material 3 in the vicinity of the anti-corrosion edge portion 23 flows down the inclination direction of the roof 1 along the anti-corrosion edge portion 23, so that water can be prevented from entering between the shielding member 4 and the roof material 3. Instead, it stays in the joint portion 22 (see FIGS. 3 and 4 ). Moreover, since the edge of the edge part of the shielding member 4 which comprises the corrosion-resistant edge part 23 is located between the shielding member 4 and the roof material 3, it is not directly exposed to wind and rain. This edge is a place where rust and the like are likely to be generated in many cases where the edge is not coated or even if the coating is not complete, but a part of the edge peels off. However, the lifespan of the shielding member 4 can be prolonged by the configuration that prevents direct exposure to wind and rain. Among the edges of the shielding member 4, there is no folded portion, that is, the edge 24 or the cutout 25 (see FIG. 3 ), and the edge between the cutout 25 and the resist edge 23 is located at a position that overlaps in the inclined plane direction. Between the roofing materials 3 and 3 , it is also possible to prevent these end edges from being directly exposed to wind and rain, thereby prolonging the life of the shielding member 4 .

The shielding member 4 provided on each layer of the roofing material 3 so as to hide the gap 5 in this way is a plate-shaped member that is bent along the concave core 21 so as to have the same angle as the angle of the concave portion 11 of the cladding board 2 , and the shielding member 4 has a structure in which two engaging portions 22 and 22 are provided in a manner of sandwiching the concave core 21, and the engaging portion 22 is connected to an edge of the shielding member 4 connected to one end of the concave core 21. The roof material 3 can be inserted in a state folded so as to be spaced apart from the main body of the shielding member 4 , and the appearance of the concave portion 10 of the roof 1 can be prevented from deteriorating with such a simple configuration. In addition, the shielding member 4 is provided in a state in which the roofing material 3 is inserted into the joint portion 22 from the edge portion 3b side of the roofing material 3 on the lower side in the slope direction, and the concave core 21 is above the groove 12 along the groove 12. The shielding member 4 is at least partially provided with a fixing area 26 on both sides of the concave core 21 that extends further to the opposite side of the concave core 21 than the hanger 13; Since the fixing area 26 is fastened by the nails 15, it is fixed to the roof material 3 , the shielding member 4 can be firmly fixed.

In the present embodiment, although the first fixing member and the second fixing member are the nails 14 and 15, respectively, they may be rivets, bolts, or the like.

In the present embodiment, although the plurality of hangers 13 are provided so as to extend from the grooves 12 in the vertical direction relative to the grooves 12 , this is not intended to limit the present embodiment. As long as the hanger 13 is a structure in which the groove 12 is stretched to both sides and fixed, the angle of the hanger 13 relative to the groove 12 can be greater than 0° and less than 180°, that is, not parallel to the groove 12 That's it.
