Description

  The present invention relates to a panel attachment used when a panel such as a photovoltaic power generation panel is attached to a gantry, and a panel attachment structure using the panel attachment.

  The photovoltaic power generation system is configured by fixing a large number of photovoltaic power generation panels on a gantry. After the solar power generation panel is positioned and placed on the gantry, it is fixed to the gantry by fastening bolts inserted into the gantry and the mounting holes of the solar power generation panel (see, for example, Patent Document 1).

  However, if the mounting holes are formed in advance in the gantry and the photovoltaic power generation panel, it is necessary to accurately insert the bolts into the mounting holes after the photovoltaic power generation panel is accurately placed at the appropriate position of the gantry. And fixing the photovoltaic power generation panel to the gantry becomes complicated.

  Therefore, it has been proposed that the gantry is made of a wooden support and the photovoltaic power generation panel is fixed to the gantry via a mounting bracket. The mounting bracket is attached to the pedestal with a wood screw screwed into the support member in a state where the solar power generation panel is pressed against the support member, and the solar power generation panel can be easily fixed to the pedestal.

  However, when a large number of photovoltaic panels are arranged in a matrix and are fixed to the gantry via mounting brackets, an interval for arranging the mounting brackets is necessary between adjacent photovoltaic panels. A part of the support member is exposed in the space between the adjacent photovoltaic power generation panels in view. Since the solar power generation system is disposed outdoors, a part of the support material is exposed to rain, dew, snow, and the like. In order to prevent this, if caulking is performed between the adjacent photovoltaic power generation panels, the fixing operation of the photovoltaic power generation panel with respect to the gantry becomes complicated, and if the covering member is inserted, the cost increases. Such a problem occurs not only when the photovoltaic power generation panel is fixed to the gantry, but also regardless of the material of the support member constituting the gantry.

  It is an object of the present invention to allow the upper surface of a part of a pedestal exposed at the interval between adjacent panels to be covered with a fixture that fixes a plurality of panels to the pedestal, and eliminates the need for caulking work and insertion work of a covering member. It is an object of the present invention to provide a panel mounting tool and a panel mounting structure that can realize improvement in performance and cost reduction.

  The panel fixture of the present invention is used when a plurality of panels are fixed on a gantry with a space therebetween, and includes a space defining portion, a contact portion, a covering portion, and a fixing portion. The interval defining portion abuts on each of the side surfaces facing each other in two adjacent panels of the plurality of panels to define the interval. The abutting portion abuts on each edge surface of two adjacent panels. The covering portion covers a range equal to the interval in the width direction that is longer than the portion positioned at the interval of the gantry in the length direction along the side surfaces facing each other in the two adjacent panels in plan view and orthogonal to the side surface. Arranged above. The fixing portion fixes the position with respect to the gantry.

  When a plurality of panels are placed on the gantry with their back surfaces in contact with the upper surface of the gantry, and the position with respect to the gantry is fixed by the fixing portion, the two adjacent panels are spaced apart from each other by the interval defining portion. The abutting portions abut against the respective edge surfaces. The two panels are fixed to the gantry while being sandwiched between the upper surface of the gantry and the contact portion. Further, the covering portion covers a range equal to the interval in the width direction that is longer than the portion positioned at the interval of the gantry in the length direction along the side surfaces facing each other in the two adjacent panels in plan view and orthogonal to the side surface. It is arranged above the gantry. A part of the pedestal exposed from the interval between the two adjacent panels in plan view is reliably covered with the covering portion.

  In this configuration, two spacing defining portions and two abutting portions are provided, and each of the two spacing defining portions has a first end continuous to one end of each of the two abutting portions, It is preferable that the 2nd edge part of this shall be followed by the both ends of a coating | coated part. The gap defining portion and the abutting portion can be continuously arranged in this order on both sides with the covering portion interposed therebetween, and can be integrally formed by bending one plate material at four locations.

  Moreover, it is preferable that a coating | coated part is equipped with the inclined surface which inclines toward a mount frame at the both ends of the direction along a side surface. Rain, snow, or the like that has fallen on the covering portion can be dropped downward through the inclined surface.

  Furthermore, it is preferable to provide a sheet-like packing that is opposed to the entire back surface of the space defining portion, the contact portion, and the covering portion. It is possible to prevent rain, snow, or the like that has fallen on the surface of the panel from penetrating between the panel fixture and the panel and wetting the mount.

  In addition, the panel mounting structure in which a plurality of panels are fixed to each other on the gantry via the panel mounting tool described above, and the spacing defining portion is opposed to each other in two adjacent panels among the plurality of panels. The panel fixture is fixed to the gantry via the fixing part in a state where the side part is in contact with each side surface and the contact part is in contact with the respective edge surfaces of the two adjacent panels.

  In this panel mounting structure, it is preferable to include an end mounting tool that is externally fitted to the protruding end of the gantry from the surface side. The end fitting includes an end contact portion and an end covering portion. The end contact portion is in contact with the edge surface of the outermost panel among the plurality of panels. The end covering portion is opposed to the end surface of the protruding end portion in a range wider than the protruding end portion, and is positioned below the surface of the protruding end portion and separated from the other portions. It is possible to reliably prevent the end of the gantry from getting wet due to rain or snow.

  According to the present invention, it is possible to improve the workability and reduce the cost by eliminating the caulking work and the covering member insertion work for the interval between the panels.

It is an external view of the panel fixture. It is an external view of the packing attached to the panel fixture. It is sectional drawing which shows the fixed state of the photovoltaic power generation panel using the panel fixture. It is an external view of the end fitting included in the panel mounting structure.

  Below, the panel fixture and panel attachment structure which concern on embodiment of this invention at the time of applying to a photovoltaic power generation unit are demonstrated, referring drawings.

  As shown in FIG.1 and FIG.2, the panel fixture which concerns on embodiment of this invention is applied to the solar power generation unit 100 installed outdoors as an example. The photovoltaic power generation unit 100 is configured by fixing a plurality of photovoltaic power generation panels 300 in a matrix on the upper surface of the gantry 200.

  The gantry 200 includes, for example, a horizontal support member 210, a vertical support member 220, and stones 230 and 240. The boulders 230 and 240 are made of, for example, concrete blocks, and the boulders 230 disposed on the front side of the gantry 200 are lower than the boulders 240 disposed on the back side. The plurality of bundling stones 230 and the plurality of bundling stones 240 are respectively arranged on a straight line. The lateral support members 210 are fixed to the upper surfaces of the boulders 230 and 240 arranged in two rows in the front-rear direction. A plurality of vertical support members 220 are fixed to the upper surfaces of the two horizontal support members 210 so that the left and right two are in contact with the back surface of one photovoltaic power generation panel 300.

  As shown in FIG. 3, in the photovoltaic power generation unit 100, a plurality of photovoltaic power generation panels 300 are arranged in a matrix, so that one photovoltaic power generation panel 300 has a maximum of four in the vertical and horizontal directions. The solar panels 300 are adjacent to each other with spaces D1 and D2. In plan view, a part of the lateral support member 210 is exposed only at the uppermost and lowermost distances D1 among the distances D1 between the two photovoltaic power generation panels 300 adjacent to the left and right. A part of the two vertical support members 220 is always exposed at a distance D2 between the two photovoltaic power generation panels 300.

  If a part of the horizontal support member 210 and the vertical support member 220 is left exposed at the interval D1 and the interval D2 in a plan view, it is deteriorated by being exposed to rain, dew, snow, or the like. For the distance D <b> 1, for example, a plate material that is larger than the exposed range of the lateral support member 210 is disposed on the upper surface of the lateral support member 210. This prevents a part of the lateral support member 210 from being directly exposed to rain, dew, snow, or the like at the interval D1. As the plate material, a corrugated plate can be used. Moreover, it replaces with a board | plate material and the panel fixture 10 of this invention can also be arrange | positioned.

  About the space | interval D2, a part of the vertical support member 220 exposed to the space | interval D2 is coat | covered using the panel fixture 10 for fixing the photovoltaic power generation panel 300 to the mount frame 200. FIG. In this example, two vertical support members 220 are located on the back surface of each photovoltaic power generation panel 300, and the top and bottom of one photovoltaic power generation panel 300 are excluded except those arranged at the top and bottom. The vertical support member 220 is exposed from four places. Since the panel fixture 10 is disposed at each exposed location, one photovoltaic power generation panel 300 excluding those disposed at the uppermost and lowermost portions is fixed to the gantry 200 with the four panel fixtures 10.

  As shown in FIG. 4, the panel fixture 10 includes two interval defining portions 11A and 11B, two contact portions 12A and 12B, and a covering portion 13 as an example. The two space defining portions 11A and 11B have first end portions 111A and 111B that are perpendicular to the respective base end portions of the two contact portions 12A and 12B, and the second end portions 112A and 11B. 112B continues at right angles to both ends of the covering portion 13. Therefore, the panel fixture 10 can be formed from one metal plate by press work, for example.

  A total of four locking pieces 15 protrude from the open ends of the contact portions 12A and 12B at both ends in the longitudinal direction. In addition, the hole 131 is formed in the covering portion 13 at two places. Both end portions in the longitudinal direction of the covering portion 13 are bent downward to form inclined surfaces 14A and 14B. The length of the covering member 13 excluding the inclined surfaces 14 </ b> A and 14 </ b> B in the longitudinal direction is longer than the width of the vertical support member 220.

  When the panel fixture 10 is used in place of the plate material for preventing a part of the lateral support member 210 from being directly exposed to rain, dew, snow, or the like at the interval D1, the covering member 13 has a longitudinal length. The length of the range excluding the inclined surfaces 14 </ b> A and 14 </ b> B in the direction is made longer than the width of the lateral support member 210.

  In the panel mounting structure according to this embodiment, the panel mounting tool 10 is mounted with the packing 20 sandwiched between the photovoltaic power generation panel 300. As shown in FIG. 5, the packing 20 is a flexible sheet-like rubber body, for example, and is largely cut around the entire periphery of the panel fixture 10 in a state of being flattened. The packing 20 has cuts 21 at four locations near the two long side end portions, and has slits 22 at two locations near the two short side end portions, and is exposed at the two short side end portions. Two notches 23 are provided.

  The locking piece 15 passes through the notch 21, and the inclined surfaces 14 </ b> A and 14 </ b> B pass through the slit 22, so that the packing 20 is attached to the outside of the panel fixture 10. In addition, the part outside the slit 22 is divided into two by the notch 23.

  As shown in FIG. 6, the panel fixture 10 having the packing 20 mounted on the outside is disposed between two vertically adjacent photovoltaic power generation panels 300. The panel fixture 10 is attached to the vertical support member 220 by a wood screw 40 that passes through the hole 131 with the sponge washer 41 interposed therebetween.

  The photovoltaic power generation panel 300 is placed on the gantry 200 in order from the bottom to the top. After the lower photovoltaic power generation panel 300 is placed on the gantry 200, the panel fixture 10 is disposed at two locations on the upper side and another photovoltaic power generation panel 300 is placed on the upper side, or another solar power generation panel is placed on the upper side. After temporarily placing the photovoltaic panel 300, the panel fixture 10 is disposed between the upper and lower photovoltaic panels 300. The outer surfaces of the space defining portions 11A and 11B are in contact with the mutually opposing side surfaces of the upper and lower photovoltaic power generation panels 300 with the packing 20 interposed therebetween, and the distance D2 between the upper and lower photovoltaic power generation panels 300 is defined.

  When the wood screw 40 penetrating through the hole 131 with the sponge washer 41 interposed therebetween is screwed into the vertical support member 220, the back surfaces of the contact portions 12A and 12B are bonded to the respective edge surfaces of the upper and lower photovoltaic power generation panels 300. And the respective edge portions of the upper and lower photovoltaic panels 300 are sandwiched between the back surfaces of the contact portions 12A and 12B and the front surface of the vertical support member 220. Accordingly, the respective edge portions of the upper and lower photovoltaic power generation panels 300 are fixed to the gantry 200.

  Further, by sandwiching the packing 20 between the panel fixture 10 and the photovoltaic power generation panel 300, rain, snow, or the like that has fallen on the surface of the photovoltaic power generation panel 300 is brought into contact with the contact portions 12A, 12B and the photovoltaic power generation panel 300. It is possible to prevent the gantry 200 from being wetted between the two.

  At this time, a portion of the vertical support member 220 positioned at the interval D2 is covered by the covering portion 13 positioned above and is not directly exposed to rain, snow, or the like. Rain, snow, or the like that has fallen on the upper surface of the covering portion 13 falls to the left and right outer sides of the vertical support member 220 via the inclined surfaces 14A and 14B. Since the gap between the hole 131 and the wood screw 40 is blocked by the sponge washer 41, rain, snow, or the like that has fallen on the covering portion 13 does not fall downward from the hole 131.

  Note that the heights of the space defining portions 11 </ b> A and 11 </ b> B are sufficiently shorter than the height of the photovoltaic power generation panel 300. For this reason, the surface of the vertical support member 220 does not contact not only the back surface of the covering portion 13 but also the packing 20, and air can be circulated. Further, by attaching one of the parts divided by the cuts 23 in the packing 20 to the side surface and the back surface of the photovoltaic power generation panel 300 via a double-sided tape or the like, rain or snow that has fallen on the surface of the photovoltaic power generation panel 300 Or the like can be prevented from falling on the surface of the vertical support member 220 along the side surface and the back surface.

  As shown in FIG. 2, the upper and lower ends of the vertical support member 220 are located inside the photovoltaic power generation panel 300 located at the uppermost and lowermost positions in plan view, and are directly exposed to rain, snow, and the like. It will never be. However, it is necessary to fix the upper edge part of the photovoltaic power generation panel 300 located at the uppermost part and the lower edge part of the photovoltaic power generation panel 300 located at the lowermost part to the gantry 200. Therefore, the panel mounting structure according to this embodiment includes end fittings 30 that are mounted on the upper and lower ends of the vertical support member 220.

  As shown in FIG. 7, the end fitting 30 includes an end contact part 31, a side contact part 32, a back contact part 33, a first holding part 34, a second holding part 35, and a third holding part 36. , An end covering portion 37 is provided. As an example, the portion excluding the end covering portion 37 is integrally formed by pressing one metal plate.

  The end fitting 30 is fitted to the upper and lower ends of the vertical support member 220 by fitting the back contact portion 33 and the first to third holding portions 34 to 36 to the four surfaces of the protruding end portion 221 of the vertical support member 220. Installed. Specifically, after the end fixture 30 is temporarily placed on the protruding end 221 of the vertical support member 220, the uppermost or lowermost photovoltaic panel 300 is placed on the gantry 200, and the photovoltaic panel 300 The end fitting 30 is positioned so that the side contact portion 32 contacts the side surface.

  At this time, the end surface 222 of the vertical support member 220 is positioned at an intermediate portion of the back contact portion 33 in the longitudinal direction (vertical direction) of the vertical support member 220. Further, the end contact portion 31 faces the surface of the photovoltaic power generation panel 300. In this state, the end fitting 30 is fixed to the vertical support member 220 by screwing an unillustrated wood screw through the hole 351 into the vertical support member 220.

  A leaf spring 38 is formed by pressing in the vicinity of the end of the back contact portion 33 where the side contact portion 32 continues. The photovoltaic power generation panel 300 is fixed to the gantry 200 with the edge surface elastically sandwiched between the end contact portion 31 and the leaf spring 38.

  The end cover portion 37 has an L-shape that is in close contact with the outside of the end contact portion 31 and the side contact portion 32, and the lower end portion is not only the vertical support member 220 but also other portions of the end fixture 30. Extends downward without contact. Further, the end cover portion 37 is formed wider than the width of the end surface 222 of the vertical support member 220.

  Rain, snow, or the like that has fallen on the end cover member 37 falls downward only from the lower end portion of the end cover member 37 and does not reach the vertical support member 220 through other portions. As a result, it is possible to prevent deterioration at the protruding end portion 221 of the vertical support member 220.

  In addition, the panel fixture of this invention and a panel attachment structure are applicable not only to a photovoltaic power generation unit but other units comprised by fixing a some rectangular panel to a mount frame.
