  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a perspective view showing a first embodiment of a support member mounting structure according to the present invention. 2 is a cross-sectional view showing the support member mounting structure of the first embodiment as seen from the side, and FIG. 3 is a cross-sectional view of the support member mounting structure of the first embodiment as seen from the front. is there.

  The attachment structure of the first embodiment includes a support fitting (support member) 1 for supporting a structure, three drill screws (screw members) 2, and three attachments for attaching the support fitting 1 to each drill screw 2. Bolts (fixing members) 3, each drill screw 2 is pierced through the metal roof tile 5 of the roof 4 and screwed into the base plate 6, and each bolt 3 is passed through each hole of the bottom plate 1 b of the support metal 1. The support fitting 1 is attached and fixed by being screwed into the female screw of the head (receiving member) 2a of each drill screw 2.

  The roof 4 is a metal tile 5 placed on a base plate 6 and fixedly supported. The metal roof tile 5 is a general-purpose product that is commercially available for homes, and is formed by forming a thin steel plate into a roof mold, plating the surface, and applying a synthetic resin paint.

  4A, 4B, and 4C are a plan view, a side view, and a cross-sectional view taken along line BB in FIG. As shown in FIGS. 4A to 4C, the support fitting 1 is formed by cutting a steel plate and plating the surface thereof, and is bent upward at both sides of the bottom plate 1b and the bottom plate 1b. And a pair of side plates 1c facing each other. Both the bottom plate 1b and the side plates 1c are flat. The bottom plate 1b is formed with three holes 1a through which the respective bolts 3 pass at equal intervals, and each side plate 1c is formed with a respective screw hole 1d.

  Next, the construction procedure of the mounting structure of the first embodiment will be described. First, as shown in FIG. 5, an O-ring (water-stop member) 7 made of an elastic member such as rubber is fitted into each drill screw 2, and each drill screw 2 is supported in the arrangement region of the support fitting 1 on the metal roof tile 5. Positioning at the same interval as each hole 1a of the metal fitting 1, screwing each drill screw 2 while rotating it, penetrating the sharp tip of each drill screw 2 through the metal roof tile 5, and further screwing each drill screw 2 into the base plate 6 Secure with. At this time, the fastening force of the drill screw 2 is adjusted such that the metal roof tile 5 is not deformed and the O-ring 7 is sandwiched between the head 2a of the drill screw 2 and the surface of the metal roof tile 5 and is crushed. The O-ring 7 stops water between the head 2 a of the drill screw 2 and the surface of the metal roof tile 5.

  Thereafter, the bottom plate 1b of the support metal fitting 1 is placed on the head 2a of each drill screw 2, the holes 1a of the bottom plate 1b are overlapped with the female screws 2b of the head 2a of each drill screw 2, and each bolt 3 is attached to the bottom plate 1b. The support fitting 1 is fixed to the head 2a of each drill screw 2 by screwing into the female screw 2b of the head 2a of each drill screw 2 through each hole 1a.

  In such a construction procedure, it is not necessary to remove the metal roof tile 5, and the number of parts is small, so the construction work is simple. In particular, when the ends of metal tiles of large size (for example, the long side is 1 m or more) overlap each other, it is very difficult to remove the metal tiles, so the merit of simplifying the installation work is great. Become. In addition, some metal roof tiles are fixed by screwing in directly, and in order to attach and detach such metal roof tiles, it is necessary to attach and detach the screws. Since it is necessary to do so, complication of installation work can be avoided by not removing the metal roof tile 5.

  Further, the O-ring 7 is crushed to stop water between the head 2 a of the drill screw 2 and the surface of the metal roof tile 5, and rainwater from the hole of the metal roof tile 5 formed by the drill screw 2. Prevent intrusion.

  Further, each drill screw 2 is pierced by the metal roof tile 5 so as to be inserted into the metal roof tile 5, and is screwed and fixed to the base plate 6. In addition, the support fitting 1 is fixed by the bolts 3 in a state where the support fitting 1 is placed on and contacted with the head 2 a of each drill screw 2. For this reason, the load of the support metal 1 and the load of the structure (not shown) supported by the support metal 1 are directly applied to each drill screw 2 and are received by the base plate 6 through each drill screw 2. Almost no effect on roof tile 5. For this reason, the metal roof tile 5 is not deformed by the load of the support fitting 1 and the load of the structure, and no rain leakage due to the deformation of the metal roof tile 5 occurs.

  In the first embodiment, the metal roof tile 5 and the field plate 6 are shown. However, even if a roofing sheet is sandwiched between the metal roof tile 5 and the field plate 6 or the slate is formed on the field plate 6. Even if the roof tile is left without being removed, and the metal roof tile 5 is provided on the slate roof tile, the drill screw 2 can be screwed into the base plate 6 through the roofing sheet or the slate roof tile. Further, the drill screw 2 may be screwed into another base material such as a rafter (not shown) having sufficient strength. Moreover, you may increase / decrease the hole 1a and the drill screw 2 of the baseplate 1b of the support metal fitting 1. FIG.

  Next, a solar power generation system to which the mounting structure of the first embodiment is applied will be described. Here, the solar cell module module, which is a structure, is installed on the roof, which is an installation object. FIG. 6 is a side view showing the photovoltaic power generation system. FIG. 7 is an enlarged side view of the photovoltaic power generation system, FIG. 8 is an enlarged side view of the photovoltaic power generation system, and FIG. 9 is an enlarged view of the photovoltaic power generation system. It is a front view shown. 6 to 9, the direction A is the water flow direction (front direction), and the direction orthogonal to the water flow direction A is the horizontal direction.

  As shown in FIGS. 6 to 9, a plurality of support fittings 1 are placed on the metal roof tile 5 of the roof 4, and each support fitting 1 is attached to the roof 4 and fixed by the construction procedure described above. At this time, the two support fittings 1 are arranged along the water flow direction A to form one set, and at least four sets are arranged side by side in the water flow direction A and the lateral direction perpendicular to the water flow direction A. Therefore, at least eight support fittings 1 are arranged in the water flow direction A and the lateral direction, and an arbitrary number of support fittings 1 can be arranged. As will be described later, the arrangement interval of each support fitting 1 is set according to the mounting position of each support fitting 1 with respect to the vertical rail 12 and the size of the solar cell module 11.

  Subsequently, for each set of two support brackets 1 arranged along the water flow direction A, the vertical beam 12 is placed over the two support brackets 1.

  The vertical beam 12 has a hat-shaped cross-sectional shape including a long and narrow main plate 12a, side plates 12b bent at both sides of the main plate 12a, and flanges 12c bent outward at the edges of the side plates 12b. Three holes 12e are formed near the front end of each side plate 12b, and a long hole 12f is formed near the rear end of each side plate 12b. The inner separation distance of each side plate 12b of the vertical beam 12 is set to be the same as or slightly longer than the outer separation distance of each side plate 1c of the support metal 1, and each side plate of the support metal 1 is interposed between each side plate 12b of the vertical beam 12. The vertical rail 12 can be placed on the support fitting 1 with 1c interposed therebetween.

  After the vertical beam 12 is laid over a pair of support brackets 1 arranged in the water flow direction A, the screws of the side plates 1c of the one support bracket 1 arranged on the lower side of the water flow direction A The hole 1d is overlapped with any of the three holes 12e near the front end of each side plate 12b of the vertical rail 12, and the screw hole 1d of each side plate 1c of the other support fitting 1 disposed on the higher side in the water flow direction A. Are overlapped with the elongated holes 12f near the rear ends of the side plates 12b of the vertical beam 12. Then, the two bolts 13 are screwed into the screw holes 1d of the side plates 1c of the one support bracket 1 through the holes 12e of the side plates 12b of the vertical beam 12, and the other two bolts 13 are fixed to the vertical beam 12. The side plate 12b is screwed into the screw hole 1d of each side plate 1c of the other support fitting 1 through the elongated hole 12f and tightened. Thereby, the vertical rail 12 is arranged and fixed along the water flow direction A.

  Thus, when the vertical rail 12 is arranged and fixed along the water flow direction A for each set of two support fittings 1 arranged in the water flow direction A, as described above, at least four sets of the support fittings 1 are provided. Since the water flow direction A and the horizontal direction orthogonal to the water flow direction A are arranged side by side, at least four vertical bars 12 are arranged side by side in the water flow direction A and the horizontal direction.

  Next, the horizontal beam 14 is bridged in the horizontal direction on the front end portion of each vertical beam 12 arranged in the horizontal direction, and the locking bracket 15 is disposed on the bottom plate 14a of the horizontal beam 14 at the front end portion of each vertical beam 12. The reinforcing member 16 is disposed on the lower surface of the main plate 12a of the vertical beam 12, and the bolt 17 is provided through the hole of the bottom plate 15a of the locking bracket 15, the hole of the bottom plate 14a of the horizontal beam 14, and the hole of the main plate 12a of the vertical beam 12. The horizontal crosspiece 14 and the locking metal fitting 15 are fixed to the front end portion of the vertical crosspiece 12 by screwing into the 16 screw holes. Further, for each row of the vertical rails 12 arranged in the horizontal direction, the horizontal rail 14 is bridged in the horizontal direction and fixed. As a result, a plurality of horizontal rails 14 are arranged long in the horizontal direction and arranged in parallel in the vertical direction.

  FIG. 10 is a perspective view showing the locking metal fitting 15. As shown in FIG. 10, the locking metal fitting 15 has a bottom plate 15a, side walls 15b formed by vertically bending both sides of the bottom plate 15a, and an upright plate 15c formed by vertically bending one side of the bottom plate 15a. A hole 15d is formed in the bottom plate 15a, and a bolt 17 is passed through the hole 15d. Receiving members 15e bent outward are formed at the upper ends of the side walls 15b. At the upper end of the standing plate 15c, a first fastening portion 15f bent to the bottom plate 15a side and a second fastening portion 15g bent to the opposite side of the bottom plate 15a are formed. Two first fastening portions 15f are provided on both sides of the upper end of the standing plate 15c, and one second fastening portion 15g is provided in the center of the upper end of the standing plate 15c, and the two first fastening portions 15f and one first fastening portion are provided. Two fastening portions 15g are alternately arranged.

  6-9, each 1st fastening part 15f of the latching metal fitting 15 faces the upper direction opposite to the water flow direction A, and the 2nd fastening part 15g of the latching metal fitting 15 is in the water flow direction A. It is suitable.

  As shown in FIG. 6, the solar cell module 11 is bridged between two horizontal rails 14 and is on a horizontal rail 14 (hereinafter referred to as a lower horizontal rail 14) disposed on the lower side in the water flow direction A. It is sandwiched between the upright plate 15c of the locking metal fitting 15 and the wall portion 14b of the horizontal beam 14 (hereinafter referred to as the upper horizontal beam 14) arranged on the higher side of the water flow direction A. Further, the front end portion of the solar cell module 11 is placed on each receiving member 15e of the locking bracket 15 on the lower horizontal rail 14, and the rear end portion of the solar cell module 11 is placed on the pedestal portion 14c of the upper horizontal rail 14. It is done. In this state, the front end of the frame member of the solar cell module 11 is engaged with each first fastening portion 15f of the locking bracket 15 on the lower horizontal rail 14, and one end of the frame member of the solar cell module 11 is engaged. The part passes over the wall part 14b of the upper horizontal rail 14 and engages with the second fastening part 15g of the locking bracket 15, whereby the solar cell module 11 is supported and fixed in an inclined state.

  Each solar cell module 11 requires two locking metal fittings 15 that engage with the front end of the frame member of the solar cell module 11 and two locking metal fittings 15 that engage with the rear end. And a total of four locking fittings 15 are required. Therefore, it is necessary to arrange the locking brackets 15 that are four times as many as the number of installed solar cell modules 11 in each cross rail 14.

  Further, since the solar cell module 11 is arranged and fixed between the standing plate 15c of the locking metal 15 on the lower horizontal rail 14 and the wall portion 14b of the upper horizontal rail 14, the lower horizontal rail is arranged. 14, the distance between the upright plate 15 c of the locking metal fitting 15 on the upper wall 14 and the wall portion 14 b of the upper horizontal rail 14 needs to be the same as or slightly wider than the width of the solar cell module 11 in the water flow direction A. In order to set a proper interval, it is necessary to appropriately set the arrangement interval of each vertical rail 11 in the water flow direction A. For this reason, as described above, at the time of the first work of arranging and fixing the support brackets 1 on the roof 4, first, according to the width of the solar cell module 11 in the water flow direction A, The arrangement interval in the water flow direction A is determined, the attachment position of each support bracket 1 to each vertical rail 11 is determined, and the arrangement interval and position of each support bracket 1 on the roof 4 according to the attachment position of each support bracket 1 It is necessary to decide.

  In such a solar power generation system, since the mounting structure of the first embodiment is applied, it is not necessary to remove the metal roof tile 5, and the construction work is simple. Further, the O-ring 7 can stop water between the head 2 a of the drill screw 2 and the surface of the metal roof tile 5 to prevent the intrusion of rainwater from the hole of the metal roof tile 5 formed by the drill screw 2. it can. Further, the load of the solar cell module 11 applied to the support fitting 1 is applied to the drill screw 2 and is received by the field plate 6, hardly applied to the metal roof tile 5, and the metal roof tile 5 is not deformed. No rain leakage due to deformation of the metal roof tile 5 occurs.

  By the way, in 1st Embodiment, although the support metal fitting 1 is attached to metal roof tiles, it is also possible to attach the support metal fitting 1 to the roof tiles made of clay, cement, ceramic, or the like. In this case, a hole for passing the drill screw 2 is formed in the roof tile, the drill screw 2 is passed through the hole in the roof tile and screwed into the base plate, and each bolt 3 is passed through each hole 1a in the bottom plate 1b of the support metal 1 to each drill screw 2. The support fitting 1 is attached and fixed to the female screw 2b of the head 2a.

  However, in the case of tiles made of clay, cement, ceramic, etc., rainwater invades through the gap between the seams where the tiles are overlapped, so the roofing sheet is superimposed on the field plate, but the drill screw 2 is screwed into the field plate. Since a hole is opened in the roofing sheet, this hole can cause rain leakage.

  Then, in order to prevent the rain leak from the hole of a roofing sheet, the support metal fitting 1 is installed in the following construction procedures. Here, first, as shown in FIG. 11, the perforations 21a that overlap the first holes 1a of the support fitting 1 are formed in the roof tile 21 made of clay, cement, ceramic, or the like. The diameter of the perforation 21a is preferably slightly larger than the outer diameter of the drill screw 2 and is, for example, about 5 mm.

  Then, as shown in FIG. 12 (a), the perforation 21a of the roof tile 21 and / or the periphery of each perforation 21a is filled with a sealing material (water-stop member) 22 before curing in a lump or the perforation 21a before curing. The sealing material 22 is filled. The sealing material 22 is, for example, for construction, and may be any of acrylic, silicon, urethane and the like. Further, the sealing material 22 has a viscosity so that the perforation 21a of the roof tile 21 and / or the lump that is placed or filled around the perimeter of the perforation 21a does not naturally fall from the perforation 21a due to its own weight before the sealing material 22 is cured. Shall have. Since the viscosity of the sealing material 22 varies depending on conditions such as the size of the perforations 21a and the use temperature, it is preferable to appropriately select the type of the sealing material 22 according to such conditions.

  Thereafter, the drill screws 2 are passed through the perforations 21a of the roof tile 21 and screwed and fixed to the base plate 6 via the roofing sheet 23 while rotating the drill screws 2. At this time, as shown in FIG. 12 (b), the sealing material 22 placed or filled in the perforation 21 a adheres to the tip and the outer periphery of the drill screw 2, and the tip of the drill screw 2 subsequently passes through the roofing sheet 23. When screwed into the main plate 6 and fixed, the sealing material 22 attached to the tip and outer periphery of the drill screw 2 is stopped on the surface of the roofing sheet 23 and accumulated in an annular shape on the outer periphery of the drill screw 2 as shown in FIG. The holes of the roofing sheet 23 are stopped by the annular sealing material 22. Further, a part of the sealing material 22 remains around the perforations 21a and the perforations 21a of the roof tile 21, and the perforations 21a of the roof tile 21 are stopped by the remaining sealing material 22.

  That is, the perforation 21a of the roof tile 21 and the sealing material 22 remaining around the perforation 21a serve as a first water stop member that stops the perforation 21a of the roof tile 21. Further, the sealing material 22 attached to the tip and the outer periphery of the drill screw 2 serves as a second water stop member that stops the hole in the roofing sheet 23. After the sealing material 22 is cured, the water stop state of the perforations 21a of the roof tile 21 and the water stop state of the holes of the roofing sheet 23 are stably maintained. For this reason, rainwater does not enter from the perforations 21a of the roof tile 21, and even if rainwater enters from the gap between the roof tiles 21, the holes formed in the roofing sheet 23 may cause rain leakage. Absent.

  Since the drill screw 2 is screwed perpendicularly to the inclined base plate 6 as shown in FIG. 13, even if the sealing material 22 is hung from the perforations 21 a of the roof tile 21, the falling location of the sealing material 22 is the screwed location of the drill screw 2. And the hole of the roofing sheet 23 cannot be stopped by the sealing material 22.

  Thereafter, as shown in FIG. 12 (c), the bottom plate 1b of the support fitting 1 is placed on the head 2a of each drill screw 2, and each bolt 3 is inserted into the female of the head 2a of each drill screw 2 through each hole 1a of the bottom plate 1b. The support fitting 1 is fixed to the head 2a of each drill screw 2 by screwing into the screw 2b.

  In this way, the perforations 21a are formed in the tile 21, and the sealing material 22 before curing is placed in a lump around each perforation 21a and / or the periphery of each perforation 21a, or the sealing material 22 before curing is filled in each perforation 21a.
