BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of the present invention will be described with reference to the drawings.
Embodiment 1 FIG.
1 to 9 show a frame 1 for fixing a panel structure according to the first embodiment. A flat panel structure 2 such as a solar module used for photovoltaic power generation is installed on a roof or the like. It is applied at the time. As shown in FIG. 2, the gantry 1 is made of a long aluminum extruded material having a C-shaped rectangular cylindrical shape having an open end 3 at the center of the upper surface as shown in FIG. is there). The upper surface divided by the opening 3 of the gantry 1 is configured as two receiving surfaces 4 for receiving the bottom surface of the outer frame of the solar module. Two opposing height surfaces 5 supporting each receiving surface 4 are connected by a lower surface 6. A flange 7 as a mounting structure that is continuous in the longitudinal direction is integrally formed in each of the height surfaces 5. Each flange 7 is formed so as to extend the lower surface 6 outward, and the thickness thereof is thicker than other portions together with the central portion 8 of the lower surface 6. The position of the flange 7 may be formed anywhere within the height direction of the height surface 5, but when the lower surface 6 is provided at the lower end in an extended state, the contact surface with respect to the mounting partner is widened and the stability is good. . The shape of the mounting structure may be a groove 9 as shown in FIGS. 3, 4 and 5 or a concave portion 10 or a convex line 11 as long as the shape can be obtained by extrusion molding.
[0017]
The fixing of the gantry 1 to a mounting partner is performed using a mounting bracket 12. As shown in FIGS. 1, 2 and 6, as the mounting bracket 12, when the mounting partner is a roofing tile 13 having a roof structure of a metal roofing tile, the flange 7 of the gantry 1 in a direction crossing the roofing rod 13. And a fixing surface 15 provided with a bolt insertion hole for fixing the screw to the tile rod 13 in a stepped manner (see FIG. 2), and a pressing surface for pressing the flange 7 An L-shaped member (see FIG. 6) in which a holding surface 16 that abuts on the height surface 5 is provided at an end of 14 is applied. 7 and 8, when the mating member is a rafter 17 having an asbestos tiled roof structure, a mounting portion 18 on which the gantry 1 is mounted in the lateral direction is provided on the upper surface. A sleeper-like mounting bracket 12 having an adjustable holding portion 19 for holding each flange 7 on both sides is applied.
[0018]
That is, as shown in FIG. 1, a plurality of rows of mounting bases 1 are mounted on mounting bases 1 by using mounting brackets 12 in a lateral direction intersecting the mounting base 1 with the upper surface facing upward. The panel structures 2 are laid side by side and fixed as a panel assembly. Each of the panel structures 2 is formed by tightening a holding member 20 covering the open portion 3 of the gantry 1 and a stopper 21 stopping on the back surface of the receiving surface 4 from the open portion 3 through a bolt 22, and pressing the holding member 20 and the stopper 21. Thus, the outer frame of the panel structure 2 is fixed to the receiving surface 4 so as to be sandwiched therebetween. Electrical wiring (not shown) is performed in the internal space of the gantry 1 using the opening 3, and the opening 3 is finally closed by the pressing member 20.
[0019]
As described above, when assembling a plurality of panel structures 2 as a panel assembly on the gantry 1 as shown in FIG. 9, the gantry 1 located on the outer peripheral portion of the panel assembly is attached to an attachment partner. A fixing means having a high fixing strength is applied for fixing, and a fixing means having a relatively lower fixing strength than a fixing means having a high fixing strength is applied to fixing the gantry 1 located at the inner part of the panel assembly to a mounting partner. When fixed in this manner, effective construction can be performed in terms of both fixing strength and workability. The application of the fixing means having a high fixing strength means that the number of the mounting brackets 12 is increased or the wood screws 23 with taps are attached to the lower surface 6 of the gantry 1 together with the mounting brackets 12 as shown by imaginary lines in FIG. 13 or the rafter 17 is to be screwed, and the application of the fixing means having a relatively low fixing strength means that the number of the mounting brackets 12 is reduced, or the lower surface 6 or This means that a wood screw 23 with a tap on the flange 7 is directly screwed to the roof bar 13 or the rafter 17.
[0020]
The panel assembly on the gantry 1 receives a stronger wind load on the outer peripheral part than on the inner part. Therefore, if the fixing strength of the gantry 1 is increased at the outer peripheral portion of the panel assembly and the inner portion is relatively reduced, the gantry 1 can be fixed with the minimum necessary fixing strength as a whole. . The gantry 1 of this embodiment basically does not require drilling for fixing to the mounting partner, and can be fixed by pressing the mounting structure such as the flange 7 by the mounting bracket 12. Since the central portion 8 of the lower surface 6 is thickened to provide strength, the tapped wood screw 23 can be screwed in from the lower surface 6 or from the flange 7 to be fixed, and fixed according to the load distribution. The fixing strength to the counterpart can be easily adjusted by a simple operation, and the number of mounting brackets 12, the number of members, and the construction cost can be reduced.
[0021]
The gantry 1 having the flange 7 in which the lower surface 6 is extended has an advantage that the fixing work of the gantry 1 can be easily performed and workability and work safety can be improved. Fixing the gantry 1 on a sloped roof is not only dangerful due to poor scaffolding but also high in difficulty. In order to fix the long gantry 1 in the direction intersecting with the inclination direction of the roof, it is necessary to fix the gantry 1 in a predetermined position while supporting the gantry 1 in a horizontal direction, which is usually dangerous for one worker. It is impossible. However, as shown in FIGS. 6 and 8, since the mounting bracket 12 has the concave portion 24 into which the flange 7 of the gantry 1 is inserted, the mounting bracket 12 on the lower side in the inclination direction of the roof is fixed at a predetermined position. If the gantry 1 is spread over the mounting brackets 12 in a mounting manner, the gantry 1 is in a temporarily fixed state in which the flange 7 is fitted into the recess 24 of the mounting bracket 12 by its own weight and is supported and does not drop. It is possible for one worker to sequentially fix the tentatively fixed gantry 1 at each fixing point.
[0022]
Embodiment 2 FIG.
The gantry 1 according to the second embodiment shown in FIG. 10 has a structure in which the mounting structure of the gantry 1 shown in the first embodiment is a flange 7 in which the lower surface 6 is extended. This is basically the same configuration as that shown in the first embodiment. Therefore, the same portions as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment, and description thereof will be omitted.
[0023]
The gantry 1 of this embodiment has a configuration in which a flange 25 extending from the lower surface 6 is provided on both lower surfaces of one or both surfaces of the height surface 5. If the flanges 25 are provided on both sides of the height surface 5 and the thickness thereof is made thick, it becomes substantially the same as the gantry 1 of the first embodiment. However, the gantry 1 does not require the flange 25 to have a function as a mounting structure, and the flange 25 requires a temporary fixing function for fixing to the roof described at the end of the first embodiment. It is. Of course, the flange 25 can be screwed from its form, and can function as a mounting structure for the gantry 1. The gantry 1 having the temporary fixing function can be inexpensively constructed by using only a small amount of material by providing the thin flange 25 having a small protrusion amount on only one side. The gantry 1 is fixed by screwing a wood screw 23 into the center of the lower surface 6 and pressing the mounting bracket 12 against the flange 25. The function of temporarily fixing the flange 25 to the mounting bracket 12 is the same as that described in the first embodiment, and a description thereof will be omitted.
