The reinforcing rib 6 is for preventing deformation of the standing portion 2 with respect to the fixing portion 1 and is formed as a triangular rib projecting inward of the intersection of the fixing portion 1 and the standing portion 2. ing. That is, the reinforcing rib 6 is formed on the inner corner side of the intersection of the fixing portion 1 and the standing portion 2, and extends between the upper surface of the fixing portion 1 and the surface of the standing portion 2 on the fixing portion 1 side. Projected. Accordingly, the reinforcing rib 6 is formed so as not to protrude from the lower surface of the fixed piece 1 and the surface of the standing portion 2 on the claw portion 4 side. The reinforcing ribs 6 are formed at a plurality of locations at substantially equal intervals along the longitudinal direction of the standing portion 2. The shapes of the reinforcing ribs 5 and 6 are not limited to triangular ribs, and can be formed in other arbitrary shapes.

  When constructing the folded-plate roofing material 9 using the hanger A as in the present invention, it is performed as follows. First, the hanging element A is attached to the roof base 8 such as a tight frame. As shown in FIG. 3, the tight frame has been conventionally used in the construction of folded plate roofing materials, and is made by bending a metal strip made of metal such as steel and having a thickness of about 2 to 5 mm. By doing so, a plurality of support ridges 22 and troughs 23 are alternately formed. The support peak portion 22 is composed of a top portion 22a and a leg portion 22b that is inclined obliquely outwardly from both ends of the top portion 22a. A substantially half of the top portion 22a is formed as a recess 24 and a leg portion. A rib 25 protrudes from the surface of 22b. Further, a hanging fixture 26 such as a bolt is provided on the bottom surface of the recess 24.

  Next, the folded roof material 9 is placed on the roof base 8 from above. As shown in FIG. 5, the folded plate roofing material 9 is formed by bending a metal plate such as a coated steel plate or a galvanized steel plate, and has an inclination direction of the roof (flow Direction). Further, the folded plate roofing material 9 is formed in a substantially U-shaped cross section, and includes a flat trough portion 50 and peak half halves 51 and 51 projecting obliquely upward from both sides thereof. ing. The upper part of one peak part half body 51 is the top part 52 which protrudes toward the opposite side to the trough part 50, and the fitting part 53 of cross-sectional substantially reverse U shape formed in the edge part of the top piece 52. It is configured. The fitting portion 53 includes a support piece 53a that protrudes upward from the end of the top piece 52, a sandwiching piece 53b that projects substantially vertically from the upper end of the support piece 53a, and a downward direction from the tip of the sandwiching piece 53b. It is comprised from the bending piece 53c which protrudes toward. Moreover, the upper part of the other peak part half body 51 is the to-be-fitted part of cross-sectional substantially reverse L shape formed from the top part 52 which protrudes toward the opposite side to the trough part 50, and the edge part of the top part 52. 54. The fitted portion 54 includes a support piece 54a that protrudes upward from the end of the top piece 52, and a pinched piece 54b that protrudes in a lateral direction substantially vertically from the upper end of the support piece 54a. And as shown to Fig.4 (a), the folded-plate roof material 9 is located between the support mountain parts 22 and 22 adjacent in the direction orthogonal to the inclination direction of a roof, and it is on the roof base | substrate 8 from the upper side. The folded roof material 9 is placed and placed.

  Next, as shown in FIG. 4B, the suspension A is attached to the roof base 8. At this time, as shown in FIG. 6 (a), the latching portion 3 and the claw portion 4 of the hanging member A are fixed to the sandwiched piece 54b of the fitted portion 54 of the folded plate roofing material 9 arranged on the roof base 8. Insert a gap. Moreover, the fixing part 1 of the hanging element A is placed on the bottom surface of the concave part 24 of the roof base 8, and the hanging element fixing tool 26 is inserted into the attachment hole 20 from below, and thereafter, as shown in FIG. Then, the fastener A such as a nut is fastened to the suspension fixture 26 so that the suspension A is attached to the roof base 8, and the folded plate roofing material 9 is locked and attached to the roof base 8 with the suspension A.

  Next, as shown in FIG. 4 (d), another folded plate roof material 9 is placed on the roof base 8 from the upper side so as to be adjacent to the folded plate roof material 9 arranged on the roof base 8. At this time, as shown in FIG. 6B, the fitting portion 53 of the folded plate roof material 9 to be newly placed is fitted into the fitted portion 54 of the existing folded plate roof material 9 from above. Thereby, the said hanging element A will be covered with the folded-plate roof material 9 newly arrange | positioned. After that, the fitting half 53 and 51 of the adjacent folded-plate roofing materials 9 and 9 are connected to each other by tightening the gouge after fitting the fitted portion 53 and the fitted portion 54 fitted together. Adjacent folded plate roofing materials 9, 9 can be connected. Moreover, as shown in FIG. 7, it becomes the folded-plate roof which the mountain part 55 and the trough part 50 which consist of the connected mountain part half bodies 51 and 51 repeated alternately. Here, as shown in FIG. 6C, the gouge fastening is performed by using a goat fastening machine such as a seamer to bend the bent piece 53c of the fitting portion 53 upward, so that the bent piece 53b and the sandwiching piece 53c. The sandwiched piece 54b is sandwiched between the two.

  Then, the claw portion 4 is also bent upward along with the bending of the bent piece 53b at the time of tightening, but in the hanging element A of the present invention, the claw portion 4 and the claw portion 4 are connected to the locking portion 3. Since the reinforcing rib 5 is not formed over the entire length, the claw portion 4 can be easily bent and the construction can be easily performed. Moreover, since the reinforcing rib 5 is protruded inward at the intersection of the standing portion 2 and the locking portion 3, the folded-plate roof material 9 and the reinforcing rib 5 after construction are prevented from contacting each other. Therefore, it is possible to prevent a gap due to the reinforcing rib 5 from being generated between the folded roof material 9 and the claw portion 4 or the locking portion 3, thereby preventing a decrease in watertightness. In addition, it is possible to prevent press-contact marks (such as dents and scratches) of the reinforcing ribs 5 on the folded plate roofing material 9. Further, the reinforcement rib 5 can reduce the deformation of the locking portion 3 with respect to the standing portion 2 and the reinforcement rib 6 can reduce the deformation of the standing portion 2 with respect to the fixing portion 1. It is possible to increase the mounting strength.

  8 and 9 show another embodiment. In this suspension A, a locking projection 7 is formed on the side surface 10 of the upright portion 2, and the other configuration is the same as that of FIG. A plurality of the locking projections 7 are formed side by side in parallel with the longitudinal direction of the standing portion 2. Moreover, the latching protrusion 7 protrudes in both the side surfaces 10 of the standing part 2, and can be formed by press work, for example.

  This hanging element A is also attached to the roof base 8 while connecting the adjacent folded-plate roofing materials 9, 9 by gobing in the same manner as described above. Further, as shown in FIG. By bending a part of the support piece 53a and the support piece 54a of the roofing material 9 in a step shape, the engaging portion 11 is formed, and the engaging portion 11 is locked to the lower surface of the locking protrusion 7. Thus, the folded plate roofing material 9 can be firmly attached to the suspension A.

  Note that the locking projection 7 may be formed only on one side surface 10 of the upright portion 2, and in this case, as shown in FIG. 10 (b), the outer surface of the upright portion 2 (the side surface on the fixed portion 1 side). It is preferable to form the locking projection 7 in 10). Moreover, the shape of the latching protrusion 7 is not specifically limited, For example, as shown in FIG.10 (c), it can also form in cross-sectional substantially triangle.
