Description

  The present invention relates to an attachment device, and more particularly, to an attachment device for attaching a frame of a solar panel on which a plurality of solar cells are mounted to a support such as a metal roof.

  Conventionally, there are solar power generation systems that install solar panels on the roof, and the installation method includes a direct installation method in which the solar panels are directly attached to the roof using mounting brackets, or on the roof. There is a rack method that attaches solar panels to a fixed rack (shelf).

  Here, the direct mounting method is an economical installation method because the solar panel is directly supported by the roof, and thus a member such as a rack for supporting the solar panel is unnecessary.

  Hereinafter, a conventional solar power generation system in which a solar panel is installed by a direct attachment method will be described.

  FIG. 10 shows a solar power generation system in which a solar panel is attached to a goby type folded plate roof.

  Here, as shown in FIG. 10 (c), the goby-type folded-plate roof R is referred to as “haze tightening” between the sides of the long roof material Lm having a substantially V-shaped cross section formed by machining a thin metal plate. It has a structure formed by joining by crimping. The surface of the goby-type folded plate roof R has a corrugated shape in which the linear concave portions Pa or the linear convex portions Pb are repeatedly arranged. It is installed to be inclined so that it becomes a road. On the upper surface of the linear convex portion Pb of the goby type folded plate roof R, a strong linear joint portion (hereinafter referred to as a goby portion) Rc formed by caulking is formed.

  In the direct mounting method, in the case of horizontal installation in which the longitudinal direction of the solar panel S is orthogonal to the inclination direction (the direction in which rainwater flows) of such a goby type folded plate roof R (FIG. 10A). ) And the case of vertical installation (FIG. 10B) in which the longitudinal direction of the solar panel S is parallel to the inclination direction of the goby-type folded-plate roof R (the direction in which rainwater flows). . In addition, in the figure, 200a is a horizontal type solar power generation system, and 200b is a vertical type solar power generation system.

  Since the installation procedure is the same in both cases, the direct attachment method in the case of vertical installation (FIG. 10B) will be specifically described below.

  FIG. 11 is an enlarged view of the portion B in FIG. 10B, showing the positional relationship between the solar panel and the goby portion Rc of the goby folding plate roof, and FIG. 12 is a diagram for explaining this solar mounting bracket. Yes, FIG. 12A shows a structure of a solar mounting bracket for enlarging the portion C of FIG. 11 and attaching the solar panel S to the gore part folded plate roof. FIG. 12B and FIG. 12C show the pressing member and the panel mounting disk of the solar mounting bracket.

  The solar panel S includes a rectangular panel body Spb including a plurality of solar cells arranged in a matrix, and a holding frame Spf (hereinafter also simply referred to as a frame) that accommodates and holds the panel body Spb. Have. The panel main body Spb has a light receiving part Spb1 in which a plurality of solar cells are arranged and in which photoelectric conversion is performed, and an outer peripheral area Spb2 provided along the outer periphery of the light receiving part Spb1 in which photoelectric conversion is not performed. The outer peripheral region Spb2 is a gap region between the frame Spf and the light receiving part Spb1. In the case of the vertical installation, the panel body long side portion of the holding frame Spf is aligned with the goby portion Rc of the goby folding plate roof R, and the solar panel holding frame Spf as shown in FIG. Is fixed to the goby part Rc.

  This will be specifically described below.

  The solar mounting bracket 200 used here is mounted on a bracket main body 230 fixed to the seam portion Rc of the seam-type folded plate roof R and a bolt member 221 protruding from the upper surface portion of the bracket main body 230 to mount a solar panel. A panel mounting disk 220 to be placed, and a pressing metal fitting 210 that presses the holding frame Spf of the solar panel S placed on the panel mounting disk 220. The panel mounting disc 220 has a bolt insertion hole 220a into which the bolt member 221 is inserted, and the presser fitting 210 is formed at the rectangular flat plate body 210a and at the center of both short sides of the flat plate body 210a. And a folded portion (flange portion) 210b. A bolt insertion hole 210c into which the bolt member 221 is inserted is formed at the center of the flat plate-shaped main body 210a.

  Next, a method of directly attaching the solar panel to the goby type folded plate roof will be described.

  The metal fitting body 230 of the solar attachment metal fitting 200 is attached to the goby portion Rc over the entire area of the goby folding plate roof R on which the solar panel S is installed (see FIG. 12). At this time, the metal fitting body 230 attaches the panel mounting disc 220 to the bolt member 221. Here, the mounting pitch Pf of the metal fitting body is twice the pitch Prc of the goby portion Rc in the goby folding plate roof R (see FIG. 11).

  Next, the holding frame Spf of the solar panel S is placed on the panel placement disc 220 attached to the metal fitting body 230 so that the solar panel S is positioned between the adjacent metal fitting bodies 230. Thereafter, the pressing metal fitting 210 is attached to the bolt member 221 protruding from the upper surface portion of the metal fitting body 230 between the adjacent solar panels S, and further the nut member 222 is attached to the bolt member 221 and tightened, thereby holding the pressing metal fitting. The holding frame Spf of the solar panel S is fixed to the metal fitting body 230 by 210 (see FIG. 11).

  Thus, the solar panel S can be attached to the goby folding plate roof R by using the solar mounting bracket 200 by pressing and fixing the holding frame Spf of the solar panel S to the bracket main body 230 by the presser bracket 210. (See FIG. 10B).

  In Patent Document 1, as in the case of the mounting bracket 200 shown in FIG. 12, a bolt member protruding upward from the upper surface portion of a fixing member attached to a C-shaped steel on the roof, which is a support for the solar panel S. A solar panel installation tool is disclosed in which a pressing plate is attached to the solar panel and the solar panel is sandwiched and fixed between the pressing member and the fixing member.

JP-A-8-312088

  However, when the solar panel is installed vertically by the direct attachment method, the mounting pitch Pf of the solar mounting bracket 200 is determined by the pitch Prc of the seam portion Rc in the goby-type folded plate roof R. Therefore, the mounting pitch Pf of the solar mounting bracket 200 is Under the influence of the pitch error of the portion Rc, the gaps between adjacent solar panels vary.

  FIG. 13 shows such a gap variation between adjacent solar panels.

  For example, in a normal mounting state (FIGS. 13A and 13D) in which the gap Dp between the adjacent solar panels S is the design value Da, the holding frame Spf can be pressed and fixed by the presser fitting 210.

  On the other hand, when the gap Dp between the adjacent solar panels S becomes a value (Db) smaller than the design value (Da) (FIGS. 13B and 13E), the folded portion 210b of the mounting bracket 210 becomes the solar panel. In some cases, the mounting bracket 210 cannot be mounted without entering the gap between the S.

  On the other hand, when the gap Dp between the adjacent solar panels S becomes a value (Dc) larger than the design value (Da) (FIGS. 13C and 13F), the holding metal fitting 210 is not wide enough to be held. The frame cannot be pressed and fixed.

  In a solar panel construction example with a short side of about 977 mm and a long side of about 1257 mm, the error of the mounting pitch Pf was in the range of −5 mm to +20 mm.

  Further, when the solar panel is placed horizontally by the direct mounting method, the same problem as in the case of the vertical installation occurs due to the variation in the gap between the adjacent solar panels due to the mounting error during construction.

  The present invention has been made in order to solve the above-described problems. The variation in the interval between adjacent solar panels is caused by the rotation of a pressing member for pressing the solar panel frame against the instrument body.

By fastening the nuts 34 through the horizontal bolts 33 in the through holes 35, the pair of clamping members 30 are fixed onto the goby folding plate roof R so as to sandwich the gouge portion Rc of the goby folding plate roof R.

  As shown in FIG. 3D, the pressing member 110 has a long axis Lax along the longitudinal direction and a short axis Sax that obliquely intersects the long axis Lax. When the pressing member 110 is rotated so as to straddle the frames Spf on both sides in accordance with the interval between the frames Spf on both sides of the support column (bolt) 131b, a part of the pressing member 110 receives light inside the frame Spf. The shape of the region where the pressing member 110 and the frame Spf overlap without expanding over the portion Spb1 can be made large enough to obtain the attachment strength necessary for the solar panel. The pressing member 110 is formed by punching a flat steel material, and is subjected to a treatment such as galvanization.

  As shown in FIG. 3D, the pressing member 110 includes a first portion 110a that presses the frame Spf on one side of the support 131b, and a second portion 110b that presses the frame Spf on the other side of the support 131b. The distance between the first pair of points where the first straight line of the plurality of straight lines passing through the rotation center Cr of the pressing member 110 intersects the outer periphery of the pressing member 110 is The distance between the second pair of points where the second straight line intersects the outer periphery of the pressing member is different.

  Specifically, the pressing member 110 of the first embodiment includes six first sides 111a and 111b facing each other, second sides 112a and 112b facing each other, and third sides 113a and 113b facing each other. It has a square shape. Here, the size relationship of the interval W11 between the first set of sides 111a and 111b facing each other, the interval W12 between the second set of sides 112a and 112b facing each other, and the interval W13 between the third set of sides 113a and 113b facing each other is W11. <W12 <W13. Further, reinforcing beats B1, B2, and B3 are formed on the flat plate member 111 constituting the pressing member 110 along the direction intersecting each side 111a, 111b, 112a, 112b, 113a, and 113b.

  Note that the shape of the holding member 110 is not limited to the above shape, and other point-symmetrical multi-points in which the distance between a pair of opposing parallel sides is different from the distance between the other pair of opposing parallel sides. It is not limited to a rectangular shape, and it is not limited to a point-symmetrical one, and variations in the spacing between adjacent solar panels can be absorbed by the rotation of this pressing member, and at that time, part of the pressing member is the panel body inside the frame. It is sufficient that the area of the region where the pressing member and the frame overlap with each other can be wide enough to obtain the strength necessary for mounting the solar panel.

  Next, a method for attaching the solar panel to the goby type folded plate roof R using the attachment device 100 will be described.

  FIG. 3 is a diagram for explaining a method of absorbing the variation in the distance between adjacent solar panels (distance between panels) by the fixture according to Embodiment 1 of the present invention. The method (FIG. 3 (a)-FIG.3 (c)) which switches an angle to 3 directions, and the shape (FIG.3 (d)) of this pressing member are shown.

  The work of attaching the fixture main body 101 of the fixture 100 to the goby portion Rc over the entire area of the goby folding plate roof R on which the solar panel S is installed is to attach the bracket main body 230 of the conventional mounting fixture 200 to the goby portion Rc. It is the same as work. At this time, the panel mounting plate 120 is attached to the fixing device 130 of the device main body 101 by the bolt 131a and the nut 131b. Also in the first embodiment, the mounting pitch Pf of the instrument main body 101 is, for example, twice the pitch Prc of the goby portion Rc in the goby folding plate roof R as described in the prior art (see FIG. 11).

  Next, the holding frame Spf of the solar panel S is mounted on the panel mounting plate 120 of the instrument main body 101 so that the solar panel S is positioned between the adjacent instrument main bodies 101. Thereafter, the bolt 131b is inserted into the elongated hole 122a from the lower side of the panel mounting plate 120, the tip of the bolt 131b is inserted into the bolt hole 114a of the holding member 110, and the nut 132b is attached to the tip of the bolt 131b.

  Before tightening the nut 132, the pressing member 110 is rotated so that the pressing member 110 straddles the frames Spf of the solar panels on both sides in accordance with the interval between the solar panels S located on both sides of the pressing member 110.

  For example, when the separation distance Dp of the solar panels is D11 and D11 ≦ W11 ≦ (D11 + 2Fw + 2Sw) (Fw is the width of the frame, Sw is the width of the gap region), as shown in FIG. The rotational position of the pressing member 110 is determined so that the frame Spf is pressed by the first pair of sides 111a and 111b of the pressing member 110 facing each other. In this state, the bolts 131b and 132b are tightened and the frame Spf is paneled by the pressing member 110. It is desirable to fix to the mounting plate 120. Thus, the area of the contact portion between the frame and the pressing member 110 can be secured over the length of the sides 111a and 111b while avoiding that a part of the pressing member 110 protrudes from the light receiving portion Spb1 inside the frame Spf. The frame Spf can be fixed with a pressing force necessary for mounting the solar panel.

  Further, when the separation distance Dp of the solar panels S is D12 (> D11) and D12 ≦ W12 ≦ (D12 + 2Fw + 2Sw), as shown in FIG. The rotation position of the pressing member 110 is determined so that the frame Spf is pressed by the sides 112a and 112b, and in this state, the bolts 131b and 132b are tightened to fix the frame Spf to the panel mounting plate 120 by the pressing member 110. desirable. Thus, the area of the contact portion between the frame Spf and the pressing member 110 is extended over the length of the sides 112a and 112b while avoiding that a part of the pressing member 110 protrudes on the light receiving part Spb1 inside the frame Spf. The frame Spf can be fixed with a pressing force necessary for attaching the solar panel.

  Moreover, when the separation distance Dp of the solar panels S is D13 (> D12) and D13 ≦ W3 ≦ (D13 + 2Fw + 2Sw), as shown in FIG. It is desirable that the rotation position of the pressing member 110 is determined so that the frame Spf is pressed by the sides 113a and 113b, and the bolts 131b and 132b are tightened in this state and the frame Spf is fixed to the panel placing plate 120 by the pressing member 110. . As a result, the area of the contact portion between the frame and the pressing member 110 can be secured over the length of the sides 113a and 113b while avoiding a part of the pressing member 110 from protruding onto the light receiving part Spb1 inside the frame Spf. The frame Spf can be fixed with a pressing force necessary for mounting the solar panel.

  As described above, in the first embodiment, the pressing member 110 has a hexagonal shape including the first sides 111a and 111b facing each other, the second sides 112a and 112b facing each other, and the third sides 113a and 113b facing each other. The relationship between the distance W11 between the first sides 111a and 111b facing each other, the distance W12 between the second sides 112a and 112b facing each other, and the distance W13 between the third sides 113a and 113b facing each other is expressed as W11 <W12 <. W13. Thereby, even if the distance of the solar panel S located on both sides of the fixture 100 varies, the pair of the pressing members 110 for adjusting the rotational position of the pressing member 110 and pressing the frame Spf of the solar panel S is adjusted. By selecting and properly using the side from any one of the first to third sides facing each other, the fixture 100 can absorb the error in the solar panel mounting pitch Pf. As a result, regardless of variations in the mounting pitch Pf of the solar panels, the frame Spf of the solar panel S is pressed by the pressing member 110 with a sufficient pressing force necessary for mounting the solar panel S, and one of the pressing members 110. The part can be fixed to the instrument body 101 without blocking the surface of the light receiving part Spb1 of the solar panel S.

A bolt insertion hole 141d for inserting the column 131b is formed (see FIG. 4B). When the pressing member 140 is rotated so that the pressing member 140 straddles both frames according to the distance between the frames on both sides of the column (bolt) 131b of the panel mounting plate 120, a part of the pressing member 140 becomes the frame Spf. The area of the region where the pressing member 140 and the frame Spf overlap can be made large enough to obtain the mounting strength of the solar panel, while preventing it from protruding onto the light receiving part Spb1 of the inner panel body Spb. It has a shape. The holding member 140 is formed by punching a flat steel material, and is subjected to a treatment such as galvanization.

  Flange 140e and 140f are integrally formed with the plate-like main body 141 by bending a part of the plate-like main body 141 downward at the end portion of the plate-like main body 141 of the pressing member 140. The flanges 140e and 140f restrict the rotation of the pressing member 140 by contacting the side surface of the frame member Spf of the solar panel S.

  The pressing member 140 has a first portion 140a that presses the frame Spf on one side of the column (bolt) 131b to which the pressing member 140 is attached, and a second portion 140b that presses the frame Spf on the other side of the column 131b. doing. The distance between the first pair of points where the first straight line of the plurality of straight lines passing through the rotation center Cr of the pressing member 140 intersects the outer periphery of the pressing member is the second straight line of the plurality of straight lines. The distance between the second pair of points intersecting the outer periphery of the pressing member is different. In each of the first portion 140a and the second portion 140b, the outer tangent line passing through one point of the first pair of points and the outer periphery passing through one point of the second pair of points. The tangent lines are adjacent to each other and form an obtuse angle.

  Specifically, the pressing member 140 according to the second embodiment has a shape including first opposing linear sides 141a and 141b and opposing second curved sides 142a and 142b. Here, the interval between the opposing first linear sides 141a and 141b is W20. The distance between the tangent lines at the pair of points Pa1 and Pb1 facing each other across the rotation center Cr on the second curved sides 142a and 142b facing each other is W21. The distance between the tangent lines at the pair of points Pa2 and Pb2 facing each other across the rotation center Cr on the second curved sides 142a and 142b facing each other is W22. The interval between the tangent lines at the pair of points Pa3 and Pb3 facing each other across the rotation center Cr on the second curved sides 142a and 142b facing each other is W23. Here, the size relationship between the intervals W20, W21, W22, and W23 is W20 <W21 <W22 <W23.

  Further, the curved shapes of the second curved sides 142a and 142b are rotated until the flanges 140e and 140f are in contact with the side surface of the frame member Spf of the solar panel S in a state in which the pressing member 140 is mounted on the column 131b. It is preferable that the point on the second curved sides 142a and 142b that is closest to the light receiving portion Spb1 of the solar panel S is a curved shape that does not enter the light receiving region Spb1 of the solar panel S.

  In addition, the shape of the pressing member 140 including the opposing linear sides 141a and 141b and the opposing curved sides 142a and 142b is not limited to the above, and variation in the spacing between adjacent solar panels. Can be absorbed by the rotation of the pressing member 140, and the area of the region where the pressing member and the frame overlap is set so that a part of the pressing member 140 does not protrude on the light receiving part Spb <b> 1 inside the frame. Any shape that can be made sufficiently wide to the extent necessary for mounting the optical panel may be used.

  Further, a reinforcing beat may be formed on the flat plate member 141 constituting the pressing member 140 in the same manner as the pressing member 110 of the attachment device of the first embodiment.

  FIG. 5 is a diagram for explaining a method of absorbing the variation in the distance between adjacent solar panels (inter-panel distance) by the fixture according to Embodiment 2 of the present invention. The method (FIG. 5 (a)-FIG.5 (c)) which changes a rotation angle, and the shape (FIG.5 (d)) of a pressing member are shown.

  The operation of attaching the mounting fixture 100a to the goby-type folded-plate roof R on which the solar panel S is installed is the same as that of the mounting fixture 100 of Embodiment 1, and therefore the operation of attaching the solar panel S to the fixture main body 130 of the mounting fixture 100a Will be described.

  A holding frame (hereinafter simply referred to as a frame) Spf of the solar panel S on the panel mounting plate 120 mounted on the fixing device 130 so that the solar panel S is positioned between the fixing devices 130 of the adjacent device main bodies 101. Is placed. Thereafter, the bolt 131b is inserted into the elongated hole 122a from the lower side of the panel mounting plate 120, the tip of the bolt 131b is inserted into the bolt hole 141d of the holding member 140, and the nut 132b is attached to the tip of the bolt 131b.

  Before the nut 132b is tightened, the pressing member 140 is rotated until the flanges 140e and 140f abut against the solar panel frames Spf on both sides of the pressing member 140. Thereby, the pressing member 140 is positioned so that the pressing member 140 straddles the frames Spf of the solar panels on both sides.

  In this state, for example, the separation distance Dp of the solar panels is D21, and a pair of points Pa1 and Pb1 are respectively formed on the light receiving portions Spb1 of the solar panels on both sides of the pressing member 140 as shown in FIG. Get closer. In this case, it is desirable that the relationship of (D21 + 2Fw) ≦ W21 ≦ (D21 + 2Fw + 2Sw) (Fw is the width of the frame Spf and Sw is the width of the gap region (outer peripheral region) Spb2) is satisfied.

  In this state, the frame Spf is fixed to the panel mounting plate 120 by the pressing member 140 by tightening the nut 132b to the bolt 131b. Thereby, while avoiding that a part of the pressing member 140 protrudes to the light receiving part Spb1 inside the frame Spf, the area of the contact portion between the frame and the pressing member 140 is set to a sufficient pressing force necessary for mounting the solar panel. Thus, the frame Spf can be made wide enough to be fixed.

  When the separation distance Dp of the solar panels S is D22 (> D21), as shown in FIG. 5 (b), a pair of points Pa2 and Pb2 are light receiving portions of the solar panels on both sides of the pressing member 140, respectively. It is closest to Spb1. In this case, it is desirable that the relationship of (D22 + 2F2) ≦ W22 ≦ (D22 + 2Fw + 2Sw) holds. In this state, the nut 132b is fastened to the bolt 131b, and the frame Spf is fixed to the panel mounting plate 120 by the pressing member 140. This prevents the pressing member 140 from partially protruding into the light receiving portion inside the frame Spf, and allows the area of the contact portion between the frame and the pressing member 140 to have a sufficient pressing force necessary for mounting the solar panel. The frame Spf can be secured to such an extent that it can be fixed.

  When the separation distance Dp of the solar panels S is D23 (> D22), as shown in FIG. 5C, the pair of points Pa3 and Pb3 are the light receiving portions of the solar panels on both sides of the pressing member 140, respectively. It is closest to Spb1. In this case, it is desirable that the relationship (D23 + 2Fw) ≦ W23 ≦ (D23 + 2Fw + 2Sw) holds.

  In this state, the frame Spf is fixed to the panel mounting plate 120 by the pressing member 140 by tightening 132b to the bolt 131b. This prevents a part of the pressing member 140 from protruding into the light receiving part Spb1 inside the frame Spf, while reducing the area of the contact portion between the frame and the pressing member 140 to a sufficient pressing necessary for the installation of the solar panel. The frame Spf can be made wide enough to be fixed by pressure.

  When the nut 132b is tightened to the bolt 131b using the electric tool, when the rotating portion of the electric tool rotates to the right during tightening, the holding member 140 rotates to the right until the flanges 140e and 140f abut against the side surface of the frame Spf. To do. For this reason, the pressing member 140 has a posture in which the straight sides 141a and 141b are rotated to the right by an angle corresponding to the separation distance Dp of the solar panel S from a posture parallel to the frame, and the nut 132b is tightened on the panel mounting table 120. (FIGS. 5A to 5C).

  In the mounting device 100a of the second embodiment having such a configuration, in addition to the effects of the first embodiment, the shape of the holding member 100a is adjacent because at least a part of the outer periphery is defined by a curve. The rotation angle of the pressing member for absorbing the variation in the gap between the solar panels can be continuously adjusted.

  In addition, flanges 140e and 140f that abut against the side surface of the frame Spf of the solar panel S and restrict the rotation of the pressing member 140 are formed at both ends in the longitudinal direction of the plate-shaped main body 141 of the pressing member 140. When attaching the pressing member 140, the rotation angle of the pressing member 140 is set to an appropriate position by rotating the pressing member 140 until the flanges 140e and 140f contact the frame Spf of the solar panel S. be able to.

  In the second embodiment, the bolt insertion hole 141d of the pressing member 140 is a round hole, but the bolt insertion hole 144d may be a long hole like the pressing member 144 shown in FIG. In this case, when the distance between the column (bolt) 131b of the instrument body 101 and the frame located on one side thereof is different from the distance between the column (bolt) 131b and the frame located on the other side, this long hole is used. The relative positions of the pressing member 144 and the frames on both sides thereof can be adjusted by 144d.

(Embodiment 3)
FIG. 6 is a view for explaining an attachment device according to Embodiment 3 of the present invention. The entire structure of the attachment device (FIG. 6A), a pressing member of this attachment device (FIG. 6B), and this attachment device. The usage method (FIG.6 (c)) is shown.

  The mounting tool 100b of the third embodiment includes a pressing member 150 having a shape different from that of the pressing member 110 in place of the pressing member 110 in the mounting tool 100 of the first embodiment.

  The pressing member 150 has a long axis Lax along the longitudinal direction and a short axis Sax perpendicular to the long axis Lax, as in the pressing member 110 of the first embodiment, and a plate-shaped main body 151 constituting the pressing member 150. A bolt insertion hole 151d for inserting the column 131b of the instrument body 101 is formed in the center of the instrument body 101. When the pressing member 150 is rotated so as to straddle both frames according to the distance between the frames on both sides of the column 131b in a state where the pressing member 150 is mounted on the column 131b of the instrument body 101, a part of the pressing member 150 is The area of the region where the pressing member 150 and the frame Spf overlap is widened to the extent necessary for the attachment of the solar panel while preventing the light receiving part Spb1 inside the frame Spf from protruding. The pressing member 150 is formed by punching a flat steel material, and is subjected to a treatment such as galvanization.

  Further, flange portions 150e and 150f are formed integrally with the plate-shaped main body 151 by bending a part of the plate-shaped main body 151 downward at both ends in the major axis direction of the plate-shaped main body 151. The flange portions 150e and 150f are in contact with the side surface of the frame member Spf of the solar panel S, thereby restricting the rotation of the pressing member 150.

  The pressing member 150 includes a first portion 150a that presses the frame Spf on one side of the support column 131b, and a second portion 150b that presses the frame Spf on the other side of the support column 131b. The distance between the first pair of points where the first straight line of the plurality of straight lines passing through the rotation center Cr of the pressing member 150 intersects the outer periphery of the pressing member is the second straight line of the plurality of straight lines. The distance is different from the distance between the second pair of points intersecting the outer periphery of the pressing member. In each of the first portion 150a and the second portion 150b, an outer peripheral side passing through one of the first pair of points and an outer peripheral side passing through one of the second pair of points are: Adjacent to each other and forming an obtuse angle.

  Specifically, the pressing member 150 of the third embodiment includes a first side 151a and 151b facing each other, a second side 152a and 152b facing each other, and a third side 153a and 153b facing each other. It has a square shape. However, in the pressing member 150 of the fixture 100b of Embodiment 3, the third set of sides 153a and 153b facing each other is an unused side that is not normally used for fixing the frame Spf, that is, when a power tool is used. is there.

  Here, the size relationship of the interval W31 between the first sides 151a and 151b facing each other, the interval W32 between the second sides 152a and 152b facing each other, and the interval W33 between the third sides 153a and 153b facing each other is W31 <W32 <. W33.

  Moreover, the bolt insertion hole 151d of the plate-shaped main body 151 which comprises the pressing member 150 is a long hole.

  Note that a reinforcing beat may be formed on the plate-shaped main body 151 constituting the pressing member 150 in the same manner as the pressing member 110 of the attachment device 100 of the first embodiment.

  In addition, the outer peripheral shape of the pressing member is not limited to the above shape, and other point-symmetrical multi-points in which the distance between a pair of opposing parallel sides is different from the distance between the corresponding pair of other sides. It may be a polygon or a polygon that is not point-symmetric.

  FIG. 7 is a view for explaining a method of absorbing variation in the distance between adjacent solar panels (inter-panel distance) by the fixture according to Embodiment 3 of the present invention. The method (FIG. 7 (a)-FIG.7 (b)) which switches an angle to 2 directions, and the shape (FIG.7 (c)) of a pressing member are shown.

  The operation of attaching the mounting fixture 100b to the goby-type folded-plate roof R on which the solar panel S is installed is the same as that of the mounting fixture 100 of Embodiment 1, and therefore the operation of attaching the solar panel S to the fixture main body 101 of the mounting fixture 100b. Will be explained.

  The holding frame Spf of the solar panel S is mounted on the panel mounting plate 120 of the instrument main body 101 so that the solar panel S is positioned between the adjacent instrument main bodies 101. Thereafter, the bolt 131b is inserted into the elongated hole 122a from the lower side of the panel mounting plate 120, the tip of the bolt 131b is inserted into the bolt hole 151d of the pressing member 150, and the nut 132b is attached to the tip of the bolt 131b.

  Before tightening the nut 132b, the pressing member 150 is rotated until the flanges 150e and 150f abut against the frames Spf of the solar panels on both sides of the pressing member 150. Thereby, the pressing member 150 is positioned so that the pressing member 150 straddles the frames Spf of the solar panels on both sides of the column 131b.

FIG. 7A shows a case where, for example, the separation distance Dp of the solar panels is D31, and the first pair of sides 151a and 151b facing each other is substantially parallel to the frames Spf on both sides of the column 131b. . In this case, it is desirable that the relationship of (D31 + 2Fw) ≦ W31 ≦ (D31 + 2Fw + 2Sw) (Fw is the width of the frame and Sw is the width of the gap region) is satisfied.
This is because, by satisfying this relationship, the area of the contact portion between the frame and the pressing member 150 is reduced between the sides 151a and 151b while preventing a part of the pressing member 150 from protruding into the light receiving portion Spb1 inside the frame Spf. This is because it can be secured over the length.

  In this state, the nut 132b is fastened to the bolt 131b, and the frame Spf is fixed to the panel mounting plate 120 by the pressing member 150. As a result, the area of the contact portion between the frame and the pressing member 150 can be secured over the length of the sides 151a and 151b while avoiding that a part of the pressing member 150 protrudes to the light receiving part Spb1 inside the frame Spf. The frame Spf can be fixed with a sufficient pressing force necessary for mounting the solar panel. At this time, when the distance between the bolt 131b of the instrument body 101 and the frame located on one side of the bolt 131b is different from the distance between the bolt 131b and the frame located on the other side of the bolt 131b, the long hole 122a of the panel receiving plate is used. The relative position of the pressing member and the frames on both sides thereof is adjusted within the range of the length of at least one of the long holes 151d of the pressing member 150.

  In FIG. 7B, the separation distance Dp of the solar panels S is D32 (> D31), and the first pair of sides 151a and 151b facing each other are substantially parallel to the frames Spf on both sides of the column 131b. Shows the case. In this case, it is preferable that the relationship of (D32 + 2Fw) ≦ W32 ≦ (D32 + 2Fw + 2Sw) holds. This is because, by satisfying this relationship, the area of the contact portion between the frame Spf and the pressing member 150 is reduced to the sides 152a and 152b while preventing a part of the pressing member 150 from protruding into the light receiving part Spb1 inside the frame Spf. This is because it can be secured over the entire length.

  In this state, the frame Spf is fixed to the panel mounting plate 120 by the pressing member 150 by tightening the nut 132b to the bolt 131b. As a result, it is possible to secure the area of the contact portion between the frame and the pressing member 150 over the length of the sides 152a and 152b while avoiding that a part of the pressing member 150 protrudes inside the frame Spf. The frame Spf can be fixed with a sufficient pressing force necessary for attachment.

  In FIG. 7B, the distance between the bolt (support) 131b of the instrument body 101 and the frame located on one side of the bolt 131b is different from the distance between the bolt 131b and the frame located on the other side of the bolt 131b. The long hole 151d of the pressing member 150 absorbs the variation in the installation position of the solar panel so that the distance from the column to the one side frame and the distance from the column to the other side frame are different.

  When tightening the nut 132b to the bolt 131b using an electric power tool, the rotating portion of the electric power tool rotates to the right during tightening, so that the holding member 150 rotates to the right until the flanges 150e and 150f abut against the side surface of the frame Spf. To do. For this reason, the holding member 150 includes at least a first posture (FIG. 7A) in which the first set of sides 151a and 151b are parallel to the frame and a second set of sides 152a and 152b in parallel to the frame. Is fixed on the panel mounting table 120 in a posture rotated to the right by an angle corresponding to the separation distance Dp of the solar panel S.

  When the nut 132b is tightened on the bolt 131b of the electric tool as described above, the pressing member 150 does not rotate counterclockwise, and the opposing third sides 153a and 153b of the pressing member 150 fix the frame Spf to the instrument body 101. It is never used to do.

  As described above, in the third embodiment, similarly to the first embodiment, the mounting tool 100b can absorb the error in the mounting pitch of the frame of the solar panel, and further, the bolt (support) 131b of the tool body 101 When the distance between the bolt 131b and the frame located on one side of the bolt 131b is different from the distance between the bolt 131b and the frame located on the other side of the bolt 131b, the length of the long hole 122a of the panel mounting plate and the length of the pressing member 150 The relative position between the pressing member and the frames on both sides of the column 131b can be adjusted by at least one long hole of the hole 151d.

  In the above embodiment, the distance between the first pair of points where the first straight line of the plurality of straight lines passing through the rotation center of the pressing member intersects the outer periphery of the pressing member, Although the case where the distance between the second pair of points where the second straight line intersects the outer periphery of the pressing member is different is described, the first pair is determined from the intersection where the first straight line and the second straight line intersect. And the distance from the intersection of the first line and the second line to the other of the first pair of points may be different, the first line and the second line The distance from the intersection where the straight lines intersect to one of the second pair of points may be different from the distance from the intersection where the first straight line and the second straight line intersect to the other of the second pair of points. .

  Moreover, although Embodiment 1 to Embodiment 3 showed what fixed the solar panel located in the both sides of the instrument main body of an attachment instrument by pressing to an instrument main body with a pressing member as an attachment instrument, When the solar panel is located only on one side of the instrument main body, the solar panel frame may be fixed to the instrument main body. Hereinafter, such an attachment instrument will be described as a fourth embodiment.

In this case, it is desirable that the relationship of (D41 + Fw) ≦ W41 ≦ (D41 + Fw + Sw) (Fw is the width of the frame Spf and Sw is the width of the gap region Spb2) is satisfied.

  This is because, by satisfying this relationship, the area of the contact portion between the frame Spf and the pressing member 160 is set to the length of the side 161a while avoiding a part of the pressing member 160 from protruding into the light receiving part Spb1 inside the frame Spf. This is because it can be secured for a long time.

  In this state, the frame Spf is fixed to the panel mounting plate 120 of the instrument main body 101 by tightening the nut 132b to the bolt 131b. As a result, the area of the contact portion between the frame and the pressing member 160 can be secured over the length of the side 161a while avoiding that a part of the pressing member 160 protrudes to the light receiving part Spb1 inside the frame Spf. The frame Spf can be fixed with a sufficient pressing force necessary for mounting the panel.

  9B, for example, Dp from the solar panel S to the rotation center Cr of the pressing member 160 is D42 (> D41), and the second side 162a is substantially the same as the frame Spf of the solar panel S. The case where it becomes parallel is shown.

  In this case, it is preferable that the relationship of (D42 + Fw) ≦ W42 ≦ (D42 + Fw + Sw) is satisfied. This is because, by satisfying this relationship, the area of the contact portion between the frame Spf and the pressing member 160 is set to the length of the side 162a while preventing a part of the pressing member 160 from protruding into the light receiving part Spb1 inside the frame Spf. This is because it can be secured for a long time.

  In this state, by tightening the nut 132b to the bolt 131b, the frame Spf is fixed to the panel mounting plate 120 of the instrument main body 101 by the pressing member 160. As a result, it is possible to secure the area of the contact portion between the frame and the pressing member 160 over the length of the side 162a while preventing a part of the pressing member 160 from protruding inside the frame Spf. The frame Spf can be fixed with a necessary sufficient pressing force.

  When tightening the nut 132b to the bolt 131b using an electric tool, the rotating portion of the electric tool rotates to the right during the tightening, so that the holding member 160 rotates to the right until the flange 160e contacts the side surface of the frame Spf. Therefore, the holding member 160 has at least a first posture (FIG. 9A) in which the first side 161a is parallel to the frame and a second posture (FIG. 9 (FIG. 9) in which the second side 162a is parallel to the frame. b)) is fixed on the panel mounting table 120 of the instrument body 101 in a posture rotated right by an angle corresponding to the distance from the solar panel S to the rotation center Cr of the pressing member 160.

  When the nut 132b is tightened on the bolt 131b of the electric tool as described above, the pressing member 160 does not rotate counterclockwise, and the third side 163 facing the pressing member 160 fixes the frame Spf to the panel mounting plate 120. It is never used to do.

  As described above, in the fourth embodiment, as in the first embodiment, the arrangement error of the solar panels located at the ends of the plurality of solar panels is calculated using only the solar panel on one side of the rotation center of the pressing member 160. It can absorb with the fixture 100c to fix.

  The bolt insertion hole of the fourth embodiment may be a long hole.

  Further, in each of the above embodiments, the outer peripheral shape of the pressing member can absorb the variation in the interval between adjacent solar panels by the rotation of the pressing member. The area of the region where the pressing member and the frame overlap so that it does not protrude from the light receiving portion may be any shape that can be widened to the extent necessary for the solar panel mounting. The outer peripheral shape is such that part of the pressing member does not protrude as much as possible on the light receiving part of the panel body inside the frame, and the area of the area where the pressing member and the frame overlap is the strength required for mounting the solar panel Any shape can be used as long as it is sufficiently wide to obtain the above. That is, the essence of the present invention is that the pressing member can absorb the variation in the interval between the adjacent solar panels by the rotation of the pressing member.

  As mentioned above, although this invention has been illustrated using preferable embodiment of this invention, this invention should not be limited and limited to this embodiment. It is understood that the scope of the present invention should be construed only by the claims. It is understood that those skilled in the art can implement an equivalent range based on the description of the present invention and the common general technical knowledge from the description of specific preferred embodiments of the present invention.
