Specifically, by making a cut in the drooping portion 22, bending it upward, and extending the cutout portion 24, a cutout portion 24 in which a portion of the drooping portion 22 is cut out as shown in FIG. A tongue piece 25 projecting upward in a hook shape is formed. Further, as shown in FIG. 4, the notch 24 is formed at a position above the rafter 2 when the steel plate roof tile 20 is installed.

In the case of a newly built house, the above-described notch 24 can be formed in advance on the steel plate tile 20. On the other hand, in the case of an existing house, the steel plate tile 20 is removed to form the notch 24 as described above, but the work is simply done by making a notch in the hanging part 22, so it is extremely easy to do. Can do.
As shown in FIGS. 1 and 4, the gantry supporter 1 is disposed at a position above the rafter 2 of the base plate 3 with the overhanging piece 13 as the eaves side. Then, the fixing piece 11 is fixed with a screw 40 at a position closer to the ridge side than the locking projection 23 of the steel plate tile 20 already installed, and attached to the field board 3. As shown in FIG. 1, the screw 40 has a length extending through the waterproof sheet 4 and the base plate 3 to the rafter 2, but the gantry support 1 is disposed above the rafter 2. Even if the screw 40 penetrates the waterproof sheet 4 and the base plate 3, no rain leak occurs. In addition, in the state where the fixing piece 11 is fixed, the overhanging piece 13 covers the upper side of the locking projection 23. That is, the locking projection 23 is located in the gap between the overhanging piece 13 and the surface of the base plate 3.

After fixing the gantry support 1, the other steel plate tiles 20 are covered with the hanging portions 22 of the other steel plate tiles 20 arranged adjacent to the ridge side on the locking projections 23 of the steel plate tiles 20 installed. Set up. At this time, the tip portion of the overhanging piece 13 and the bolt 15 of the stand support 1 were exposed from the notch portion 24 of the other steel plate tile 20, and the base portion of the overhanging piece 13 was covered with the tongue piece 25. It becomes a state.
As described above, after the gantry support 1 is installed at the joint portion between the steel plate roof tile 20 on the eaves side and the steel plate roof tile 20 on the ridge side, the washer and the nut 30 are attached to the bolt 15. The nut 30 serves not only as a fastening member but also as a spacer, and the height of the fixture relative to the roof surface can be adjusted by changing the height and number of the nuts 30 to be attached. Then, the bolt 15 provided in the bottom plate of the concave-shaped gantry receiver 60 (see FIG. 4) is fitted into the bolt 15 to which the nut 30 is attached, and the bolt 15 and the gantry receiver 60 are fixed by the fixing nut 31. Further, the vertical beam 51 of the gantry 50 is attached to the recess of the gantry receiver 60 and is fixed from the side surface of the gantry receiver 60 by the fixing screw 65. Further, as shown in FIG. 5, the horizontal beam 52 straddling the plurality of vertical beams 51 is fixed by a fixing member (not shown), and the photovoltaic power generation module 70 is attached to the grid-like frame 50 formed in this way.

In the illustrated example, the solar power generation module 70 is attached as the roof placing object 70, but a hot water panel or other placing object can also be attached.
Thus, the gantry support tool 1 according to the present embodiment has a configuration in which a flat metal plate is bent to form the support tool body 10 and the bolts 15 are welded to the support tool body 10, and thus can be easily manufactured. Further, since the bolt 15 of the overhanging piece 13 is formed so as to stand upright with respect to the fixing surface 11A of the fixing piece 11 fixed to the base plate 3, when the gantry support 1 is fixed to the base plate 3, the bolt 15 is It will always stand upright against the field board 3. Therefore, when installing the gantry 50, the gantry holder 60 is fixed to the bolt 15, and the vertical beam 51 of the gantry 50 is attached to the fixed gantry receiver 60, and the vertical beam 51 is attached in parallel to the base plate 3. Can do.

In addition, the gantry support 1 is arranged above the rafter 2 and is fixed by penetrating the rafter 2 with screws 40 for fixing the gantry support 1, so that it is difficult to stop screws such as laminated wood. Even a roof using a base material can be securely fixed. Further, since the screws 40 do not break the roof material and rain leakage does not occur, and it is not necessary to perform the fixing work more carefully than necessary, work efficiency can be improved.
In addition, since the structure of the eaves side end portion of the steel plate roof tile 20 is a hanging portion 22 bent at a right angle from the upper surface 21, the cutout portion 24 and the tongue piece 25 can be easily formed in the field. Since the tongue piece 25 formed by bending 22 is covered with the overhanging piece 13 exposed from the end of the steel plate roof tile 20, the intrusion of rainwater can be prevented.

In the above-described embodiment, the protruding piece 13 of the gantry support tool 1 is formed in parallel with the fixed piece 11, but the central axis in the length direction of the bolt 15 is fixed to the fixed surface 11A of the fixed portion. As long as it forms so that it may become a right angle, the overhang | projection piece 13 does not need to be parallel to the fixed piece 11. FIG. For example, you may form diagonally according to the inclination of a roof material. In the embodiment described above, the rising portion of the gantry support 1 is the inclined piece 12, but the rising portion may rise at a right angle from the fixed portion.
Furthermore, the gantry support tool 1 according to the present invention can be used not only for roofs made of steel sheet tiles but also for roofs using slate tiles or Japanese tiles.
