Description

  The present invention relates to a photovoltaic power generation panel gantry in which a photovoltaic power generation panel is mounted on a gantry frame in which a plurality of vertical beams and horizontal beams are connected in a grid pattern.

In recent years, solar power generation systems using solar cells are rapidly spreading from the viewpoint of environmental protection, resource saving, CO ₂ reduction, etc. In order to obtain a large amount of power generation, a plurality of solar power generation panels (solar cells) Solar cell arrays in which modules) are arranged horizontally and vertically have become common, and large-scale photovoltaic power generation facilities in which a large number of solar cell arrays are arranged side by side as mega solar and giga solar are also increasing. And since one solar cell array is large with a short side of several meters and a long side of several meters to several tens of meters, it is usually a grid-like gantry in which a plurality of vertical beams and horizontal beams are connected at the crossovers. Mounted with mounting brackets or columns at the lower side of the base frame to the base such as concrete foundations and piles provided on the ground or flat roof, and receiving metal fittings provided on the roof of the building. It is supported through metal fittings.

  In the construction construction of the photovoltaic power generation panel frame to be applied to the solar cell array, it is extremely difficult to handle in terms of size and weight in a state where the vertical frame and the horizontal beam of the frame are connected in advance. First, a plurality of lower crosspieces are mounted and fixed to the base side via the mounting brackets or support posts and mounting brackets, and then the upper crosspieces are sequentially arranged on these lower crosspieces at each crossing portion. Both the bars are connected, and the photovoltaic power generation panels are sequentially arranged and fixed on the grid-like gantry frame thus formed. However, the larger the photovoltaic panel pedestal, the greater the number of upper-side rails that support the photovoltaic panel. Therefore, it is important to align both rails when arranging a large number of photovoltaic panels accurately. At the same time, since the number of intersections of both crosspieces increases, it is desirable to facilitate the connection operation from the viewpoint of construction efficiency.

  The simplest method of connecting the vertical beam and the horizontal beam of this gantry frame is to pass a bolt through the crossing portion and fasten it with a nut, but there is a fatal problem that the connection position cannot be adjusted. Therefore, conventionally, as shown in Patent Documents 1 to 3, for example, various connection methods for making it possible to adjust the connection position between the vertical beam and the horizontal beam have been proposed.

  In the connection method of Patent Document 1, a back plate is inserted into a dovetail groove formed on the upper surface of the vertical beam at the intersection of the upper horizontal beam and the lower vertical beam, and the bottom plate of the horizontal member is inserted into the back plate. The fixing bolt is screwed through the portion. In the connection method of Patent Document 2, a clip-type fixing bracket in which a back plate portion and a latch plate are integrated is used, and a lower-side shape member having a dovetail groove on the upper surface is provided with a flange portion with a flange along both lower edges. With the upper crosspiece having crossing, the upper side section is clamped from both sides with a pair of fixing brackets with the back plate inserted in the dovetail of the lower side section section, and the lever of each fixing bracket is tilted Thus, the latch plate is engaged with the flange portion of the upper side profile. In the connection method of Patent Document 3, upper and lower horizontal rails and lower ranks are used by using a support bracket having a pair of raised portions whose surface directions are perpendicular to each other on the upper and lower sides, and each raised portion is provided with a transverse long hole. At the intersection with the vertical beam on the side, the support bracket is interposed so that the horizontal beam is fitted between the upward rising parts and the vertical beam is fitted between the downward rising parts. A nut is screwed onto a bolt that penetrates through the side wall of the vertical beam and the horizontal beam through the hole.

Japanese Patent Laid-Open No. 11-13238 (FIGS. 2 and 3) Japanese Patent Laying-Open No. 2003-35016 (FIGS. 2 to 4) JP 2003-343056 A (FIG. 1)

  However, in the connection method of Patent Document 1, since the back plate can move along the dovetail groove of the vertical member, the connection position of the horizontal member can be adjusted in the longitudinal direction of the vertical member, but the fixing bolt to be screwed to the back plate is Since it passes through the hole provided in the bottom plate portion of the cross member, there is an inconvenience that the connecting position cannot be adjusted in the longitudinal direction of the cross member. In addition, the connection method of Patent Document 2 requires a special clip-type fixing bracket and has a flange portion with a flange along the lower edge on both sides as the upper side shape member. Therefore, the material cost is high. At the same time, because the fixing bracket is fixed to the lower side profile with spring force, the fixing strength cannot be said to be sufficient, and there is a concern that displacement may occur at the connecting part when a large external force acts due to an earthquake, etc. Since a pair of fixing brackets are used for each connection position, there is a problem that the connection operation becomes complicated. Furthermore, in the connection method of Patent Document 3, the connection position can be adjusted in either the vertical beam direction or the horizontal beam direction, but the adjustment range is limited by the length range of the long hole provided in the rising portion of the support bracket. Therefore, there has been a problem that it is impossible to cope with a change in the connection position due to a difference in the size and aspect ratio of the photovoltaic power generation panel.

  In view of the above-described circumstances, the present invention can easily adjust the connection position in either the vertical beam direction or the horizontal beam direction when connecting the vertical beam and the horizontal beam of the frame as a photovoltaic power generation panel frame. The purpose of the present invention is to provide a device that can cope with a change in the connecting position due to the difference in the size and aspect ratio of the photovoltaic power generation panel without any restriction in the adjustment range, and that the connecting portion has a simple structure and can be easily connected. It is said.

  If the means for achieving the above object is shown with reference numerals in the drawings, the photovoltaic power generation panel mount according to the invention of claim 1 includes a plurality of vertical beams 1 and horizontal beams 2 connected in a grid pattern. In the photovoltaic power generation panel frame in which the photovoltaic power generation panel P is mounted on the frame frame 10 thus formed, the vertical frame 1 and the horizontal beam 2 of the frame frame 10 on the upper surface of the lower frame (the horizontal beam 2). A wide slide guide groove 21 continuous in the longitudinal direction is provided, and the frame coupling fitting 3 is fitted in the slide guide groove 21 so as to be slidable and cannot be separated from the upper side. ) Are formed on both side surfaces, and the frame connecting bracket 3 has two parallel sandwiching walls projecting upward along a direction perpendicular to the sliding direction with respect to the sliding guide groove 21. Has a portion 32b and protrudes inwardly to both sandwiching wall portions 32b and 32b A locking piece 32c is formed, and provided with fixing means (fixing bolt B, nut N, drilling tapping screw S) for fixing the frame connecting bracket 3 to the upper side rail and the lower side rail, respectively, and the sliding guide groove 21 The upper side rails are slidably fitted between the holding wall portions 32b, 32b of the frame connecting metal fitting 3 fitted to the both sides, with the locking pieces 32c on both sides inserted into the locking grooves 11 on both sides thereof, and the frame connecting The metal fitting 3, the upper side rail, and the lower side rail are each fixed by fixing means.

  According to a second aspect of the present invention, in the photovoltaic power generation panel mount according to the first aspect, the frame connecting bracket 3 includes a slide member 31 to be fitted into the slide guide groove 21 and two parallel sandwiching wall portions 32b. The receiving member 32 is arranged on the slide member, and the fixing means for the lower side rail is formed by screwing and tightening the nut N to the fixing bolt B penetrating the slide member 31 and the receiving member 32. Both side edges 22 and 22 of the sliding guide groove 21 sandwiched between the member 31 and the receiving member 32 are sandwiched.

A third aspect of the present invention, the photovoltaic panel frame of the second aspect, both sandwiching wall 32b, the substrate portion 32a and the sliding member receiving only member 32 at both outside positions of 32b of the fixing bolt B is receiving member 32 31, and a recess 31 c in which the head of the fixing bolt B fits in the lower surface of the slide member 31.

  According to a fourth aspect of the present invention, in the photovoltaic power generation panel mount according to the second or third aspect, the fixing means for the upper side rail is formed by drilling tapping screws S on the holding wall portions 32b and 32b of the receiving member 32 on the upper side rail. It is supposed to be screwed.

  According to a fifth aspect of the present invention, in the photovoltaic power generation panel gantry according to any one of the second to fourth aspects, the vertical beam 1 and the horizontal beam 2 of the gantry frame 10, the slide member 31 and the receiving member 32 of the frame connecting metal 3 However, each is made of an aluminum mold.

  Next, effects of the present invention will be described with reference numerals in the drawings. First, in the photovoltaic power generation panel gantry according to the first aspect of the present invention, the upper surface of the lower frame is formed at each intersection of the upper beam (vertical beam 1) and the lower beam (horizontal beam 2) of the frame 10. The frame coupling fitting 3 is slidably fitted in the sliding guide groove 21 so as not to be separated from the upper side, and between the both clamping wall portions 32b, 32b protruding upward of the frame coupling fitting 3, The upper side rail is slidably fitted into each locking groove 11 so that the locking piece 32c of the holding wall portion 32b is engaged, and the frame connecting bracket 3 and the upper side rail and the lower side rail are fixed respectively. It is fixed by means. Therefore, in the temporarily assembled state in which the frame connecting bracket 3 of each crossing portion is not fixed to both the crosspieces, the upper side is moved in the longitudinal direction of the lower side crosspiece by the movement along the slide guide groove 21 of the frame connecting bracket 3. In the longitudinal direction of the crosspieces, the position of the upper frame can be adjusted arbitrarily by moving the upper side crosspieces between the sandwiching wall portions 32b, 32b of the frame coupling fitting 3, so that the crossover portion of the entire gantry frame 10 is precisely positioned. By fixing the frame connecting bracket 3 of each crossing portion to both the crosspieces, the gantry frame 10 can be efficiently constructed with high dimensional accuracy without requiring frequent position correction work. In addition, due to the difference in the size and aspect ratio of the photovoltaic power generation panel P to be applied, even if the position and number of the crossing portions are changed, there is no restriction on the position adjustment range in the left-right direction and the front-back direction in each crossing portion. Since the number of fittings of the frame connecting bracket 3 to the sliding guide groove 21 of the lower side rail can be arbitrarily set, it can be handled without any problem.

  According to the second aspect of the present invention, the fixing bolt B is passed through the slide member 31 and the receiving member 32 of the frame connecting bracket 3 and the nut N is screwed and tightened, whereby both sides of the sliding guide groove 21 of the lower side rail are secured. Since the edge portions 22 and 22 are sandwiched between the members 31 and 32, the frame connecting bracket 3 can be fixed at an arbitrary position in the longitudinal direction of the lower-side beam, and the lower-side beam is fixed to the lower-side beam. Therefore, the drilling process (usually the process at the construction site) for providing these is omitted, and the work efficiency is improved, and the vertical length of the gantry frame 10 is improved. Even if the combination structure of the crosspieces 1 and the crosspieces 2 is different, the same lower side crosspieces can be shared, and the cost can be reduced by sharing the members.

  According to the invention of claim 3, the fixing bolt B lowers the base plate portion 32 a of the receiving member 32 and the slide member 31 at both outer positions of the holding wall portions 32 b, 32 b of the receiving member 32 in the frame coupling fitting 3. Since the head of the fixing bolt B is received in the recess 31c on the lower surface side of the slide member 31, the nut N is not screwed or loosened with respect to the fixing bolt B. The crosspiece 1 and the horizontal crosspiece 2 can be easily temporarily assembled without hindrance, and the position of each connecting portion is adjusted in this temporarily assembled state so that the arrangement of the entire gantry frame 10 is set accurately, and then the nut N is tightened. Each connecting part can be fixed. In addition, the frame connecting bracket 3 is fastened and fixed at two positions to the lower-side beam and is also screwed to the upper-side beam on both sides, so that both the beams are rigidly and firmly connected.

  According to the invention of claim 4, the frame connecting bracket 3 screws the holding wall portions 32 b and 32 b of the receiving member 32 with the drilling tapping screw S to the upper side rail, so that the upper side rail has There is no need to provide a screw hole or bolt insertion hole for fixing the connecting bracket. Thus, as in the case of the lower side beam, construction efficiency is improved by omitting drilling, and the vertical frame 1 and the horizontal beam of the gantry frame 10 are improved. Even if the combination structure of the crosspieces 2 is different, the same upper crosspiece can be shared, and the cost can be reduced by sharing the members.

  The horizontal beam 2 of the gantry frame 10 is made of a hollow aluminum mold having a vertical cross section having a length corresponding to three rows of the left and right arrays of the photovoltaic power generation panels P. As shown in FIGS. 1 is composed of an upper wall portion 2a inclined corresponding to the inclination of 1, a front and rear side wall portions 2b and 2c, a bottom wall portion 2d, and a partition wall portion 2e that divides the inner space vertically, and the center of the upper wall portion 2a in the width direction Has a sliding guide groove 21 continuous in the longitudinal direction. The sliding guide groove 21 has both side edges 22, 22 projecting inward with an inverted L-shaped longitudinal section, and a locking groove 21 a having a lower side of each side edge 22 recessed into the L-shaped longitudinal section. It is formed and is wide at the positions of both locking groove portions 21a, 21a.

  The vertical beam 1 of the gantry frame 10 is made of a hollow aluminum mold having a vertically long vertical section having a length slightly exceeding the total length of the front and rear array of the photovoltaic power generation panels P. As shown in FIGS. 4 and 6, both side surfaces 1b, A locking groove 11 that is recessed in an L-shaped longitudinal section is formed on the lower side of 1b, and a sliding guide groove 12 similar to the sliding guide groove 21 of the horizontal rail 2 is formed on the upper surface 1a over the entire length in the longitudinal direction. ing. The sliding guide groove 12 is for slidingly fitting the intermediate fixing bracket 9A and the end fixing bracket 9B (see FIG. 3).

  As shown in FIG. 5, the frame coupling fitting 3 includes a slide member 31 that is fitted into the slide guide groove 21 of the horizontal rail 2 and a receiving member 32 that is disposed thereon. The slide member 31 and the receiving member 32 are made of a short cut material of an aluminum mold.

  The slide member 31 has a locking strip portion 31b having an L-shaped vertical cross section on both sides in the width direction of the strip-shaped substrate portion 31a, and a pair of parallel leg pieces 31c, 31c on the lower surface side of the substrate portion 31a. The upper and lower bolt insertion holes 33 are formed on both sides in the longitudinal direction of the substrate portion 31a. The receiving member 32 includes a board portion 32a having a front-rear width corresponding to the upper plate portion 2a of the horizontal rail 2 and a left-right width corresponding to the slide member 31, and an upper side along the front-rear direction from the center side of the substrate portion 32a. A latching piece 32c having an L-shaped longitudinal section projecting inwardly is formed at the upper end of both the sandwiching wall portions 32b and 32b. Bolt insertion holes 34 in the vertical direction are formed in the left and right sides corresponding to the slide members 31, and a pair of screw insertion holes 35, 35 are formed in the upper part of each holding wall portion 32 b. The interval between the holding wall portions 32b and 32b of the receiving member 32 substantially corresponds to the width of the vertical beam 1, and each locking piece 32c can be engaged with the locking groove portion 21a of the vertical beam 1, respectively. The dimensions are set.

  In order to construct the gantry frame 10 by connecting the vertical beam 1 and the horizontal beam 2 in a lattice shape by the frame connecting metal 3, each horizontal beam before and after being fixedly supported on the concrete foundations 4A and 4B in advance as described later. 2, the sliding guide groove 21 is slid into one end side of the sliding member 31 corresponding to the crossing portion with the vertical beam 1 in a state where the fixing bolt B is inserted into each bolt insertion hole 33 from below. Combine. As a result, each slide member 31 has its locking strip portions 31b on both sides engaged with the locking groove portions 21a of the sliding guide groove 21, and each of the two fixing bolts B has its head on both leg piece portions 31c. , 31c is held in the recess 31d so as to be slidable in the slide guide groove 21 and cannot be separated upward. Next, as shown in FIG. 6, the receiving member 32 is placed on each slide member 31, and the flat washer W1 and the spring washer W2 are attached to the fixing bolt B inserted into each bolt insertion hole 34 of the board portion 32a. Nut N is screwed through. The recess 31d of the slide member 31 is set to a width that makes the head of the fixing bolt B unrotatable.

  Thus, each frame connecting bracket 3 having the receiving member 32 mounted on the slide member 31 is slidable along the longitudinal direction of the cross member 2 in a state in which the nut N is loosened. And sequentially move to each intersection. Then, at each crossing portion, as shown in FIG. 6, the vertical beam 1 is slid and fitted between the sandwiching wall portions 32 b and 32 b of the receiving member 32 of the frame connecting bracket 3 from the rear side. The locking pieces 32c and 32c of the receiving member 32 are engaged with the locking grooves 11 and 11 on both sides.

  The vertical beam 1 slidably fitted to the receiving member 32 of the frame coupling fitting 3 as described above cannot be detached upward because the locking pieces 32c and 32c are engaged with the locking grooves 11 and 11. However, it can slide in the longitudinal direction, that is, the inclined front-rear direction, and the frame connecting bracket 3 can also move in the longitudinal direction, that is, the lateral direction of the horizontal rail 2 with the nut N loosened. On the other hand, it becomes a temporary assembly state that can be displaced both in the front-rear direction and in the left-right direction. Therefore, the position of the front and rear connecting portions (crossover portions) of the vertical rails 1 with respect to the front and rear horizontal rails 2 can be adjusted in a temporarily assembled state so that the arrangement of the entire gantry frame 10 can be accurately set. Then, in this state where the arrangement is set, as shown in FIG. 4, first, the nuts Nb on both sides of the frame connecting bracket 3 are tightened, whereby the locking strip portions 31b and 31b on both sides of the slide member 31 (see FIG. 5). The side edge portions 22 and 22 (see FIG. 5) of the sliding guide groove 21 of the horizontal beam 2 are sandwiched between the frame member 32 and the base plate portion 32a of the receiving member 32, and the frame connecting bracket 3 is fixed to the horizontal beam 2. As a result, the vertical rail 1 becomes immovable in the left-right direction, and then is screwed into the side wall portion of the vertical rail 1 through the drilling tapping screw S from the outside into the screw insertion holes 34 of the holding wall portions 32b and 32b of the receiving member 32. By penetrating, the vertical beam 1 cannot be moved in the front-rear direction, and the vertical beam 1 and the horizontal beam 2 are rigidly and firmly connected at the crossing portion.

  Next, the support structure of the gantry frame 10 by the concrete foundations 4A and 4B will be described. These concrete foundations 4A and 4B consist of a pile foundation placed on the ground G or a pile foundation in which the lower part is buried in the ground, and as shown in FIGS. 7 and 8, a pilot hole drilled vertically from the top surface thereof. 40, an anchor bolt 41 is embedded and fixed in a state where a part protrudes upward through a resin binder 42. And as shown in FIG. 1 or FIG. 9, the concrete foundation 4A on the front side is set higher than the concrete foundation 4B on the rear side.

  The mounting bracket 7 is made of a short cut material of an aluminum mold, and as shown in FIGS. 7 and 8, in the other half of the horizontal plate portion 7a having a left and right long hole 71 in one half, the vertical direction A pair of vertical wall portions 7b, 7c are provided integrally with the two long holes 72 and the plurality of screw insertion holes 73 along the front-rear direction. The mounting bracket 7 has a horizontal plate portion 7a placed on the top surfaces of the concrete foundations 4A and 4B, and the anchor bolt 41 passed through the long hole 71 is attached to the nut N via the plain washer W1 and the spring washer W2. Are fixed to the concrete foundations 4A and 4B so as to be adjustable in the left-right direction within the long hole 71.

  As shown in FIG. 7, the front cross rail 2 has a lower portion fitted between the vertical wall portions 7b and 7c of the mounting bracket 7 at both ends thereof, and is one length of both vertical wall portions 7b and 7c. A nut N is fastened to a mounting bolt B that is passed through the horizontal rail 2 through the hole 72, so that the position can be adjusted in the vertical direction within the range of the long hole 72. The drilling tapping screws S are screwed in from the outside through the screw insertion holes 73 on the upper and lower sides (upper side in the drawing) of the vertical wall portions 7b and 7c. Each mounting bracket 7 is fixed in a state in which the adjacent horizontal rails 2 and 2 are in close contact with each other in the same manner.

  The rear side rail 2 has a bottom wall 2d cut at both ends at approximately half the width of the column 6 as shown in FIG. 8, and as shown in FIG. The nut 6 is fastened to the upper end of the column 6 by tightening a nut N to each mounting bolt B that is in contact with the partition wall 2e and is fitted with a substantially half width on one side, and is passed through two places above and below the fitting portion. It is supported. And in the upper end part of the support | pillar 6 arrange | positioned in the intermediate | middle in the left-right direction of the mount frame 10, the adjacent horizontal rails 2 and 2 are similarly fixed in the state which faced each end closely. Further, the lower end portion of each column 6 penetrates the horizontal rail 2 through the long holes 72 and 72 of both the vertical wall portions 7b and 7c in a state of being fitted between the vertical wall portions 7b and 7c of the mounting bracket 7. By tightening a nut N to each of the mounting bolts B, the vertical holes 7b and 7c of the mounting bracket 7 are fixed in such a manner that the position can be adjusted in the vertical direction within the range of the long hole 72. The drilling tapping screw S is screwed from the outside through the screw insertion hole 73 (see FIG. 7B) to be fixed to a predetermined height. In addition, in the upper end part of the support | pillar 6 arrange | positioned in the right-and-left both ends position of the mount frame 1, since the edge part of the crosspiece 2 fits only in the one-side half part of the left-right width, as shown in FIG.2 and FIG.3, A girder end member 23 is attached to the upper half of the cross rail that is not connected from the exterior appearance.

  As shown in FIGS. 2 and 8, the brace 8 to be attached between the support columns 6 and 6 is connected to the connection portion between the upper end portion of the support column 6 and the horizontal rail 2 and the connection portion between the lower end portion of the support column 6 and the mounting bracket 7. By utilizing one of the mounting bolts B to be used and passing the bolt B through the hollow portion at the center of the eye-shaped cross section, each end thereof is firmly fixed.

  In the photovoltaic power generation panel frame having the above-described configuration, the frame connecting bracket 3 is slid into the sliding guide groove 21 on the upper surface of the horizontal beam 2 which is the lower side at each intersection of the vertical beam 1 and the horizontal beam 2 of the frame 10. Between the holding wall portions 32b, 32b, which are movable and cannot be detached from the upper part and protrude upward from the frame connecting metal 3, the holding grooves 11 are held in the locking grooves 11 on both sides of the vertical beam 1 which is the upper side. Since the vertical beam 1 is slidably fitted in the form in which the locking piece 32c of the wall portion 32b is engaged, the frame connecting bracket 3 moves along the sliding guide groove 21 of the horizontal beam 2 in the left-right direction. Further, in the front-rear direction, the position can be freely adjusted by moving the vertical rail 1 between the sandwiching wall portions 32b, 32b of the frame connecting bracket 3. Therefore, by accurately positioning the crossing portion of the vertical beam 1 and the horizontal beam 2 in a temporarily assembled state on the entire gantry frame 10, the frame connecting bracket 3 of each crossing part is fixed to the vertical beam 1 and the horizontal beam 2. The gantry frame 10 can be efficiently constructed with high dimensional accuracy without requiring frequent position correction work.

  Further, depending on the size and aspect ratio of the photovoltaic power generation panel P to be applied, the position and number of crossing portions of the vertical beam 1 and the horizontal beam 2 in the gantry frame 10 that supports the panel (the lower side is the horizontal beam 2 as in the embodiment). If this is the case, the number of crossovers of the vertical bars 1 with respect to the horizontal bars 2 will change, but there are no restrictions on the position adjustment range in the horizontal direction and the front-rear direction at each crossing part, and the frame connecting bracket 3 for the sliding guide groove 21. Since the number of fittings can be arbitrarily set, there is also an advantage that the change in the position and number can be handled without any problem.

  The frame connecting bracket 3 in the embodiment includes a slide member 31 fitted in the slide guide groove 21 of the horizontal rail 2 and a receiving member 32 disposed on the slide member 31, and is penetrated by both members 31 and 32. By screwing and tightening the nut N to the fixing bolt B, both side edges 22 and 22 of the sliding guide groove 21 are sandwiched between the members 31 and 32 and fixed to the cross rail 2, while both of the receiving members 32 are fixed. Since the structure is such that the vertical beam 1 slidably fitted between the holding wall portions 32b and 32b is screwed using a drilling tapping screw S, it can be fixed at an arbitrary position in the longitudinal direction (left and right direction) of the horizontal beam 2. At the same time, the vertical beam 1 can be fixed to the frame connecting bracket 3 at an arbitrary position in the longitudinal direction (front-rear direction). In addition, the horizontal beam 1 and the vertical beam 2 do not require screw holes or bolt insertion holes for fixing the connecting metal fittings, so the drilling process (usually processing at the construction site) for providing these is omitted. In addition to improving the construction efficiency, the same horizontal beam 1 and vertical beam 2 can be shared even if the vertical beam 1 and horizontal beam 2 of the gantry frame 10 are different, thereby reducing costs by using common parts. obtain.

  Furthermore, in the frame coupling fitting 3 of the embodiment, the fixing bolt B penetrates the base plate portion 32a of the receiving member 32 and the slide member 31 from the lower side at both outer positions of the holding wall portions 32b, 32b of the receiving member 32. In addition, since the head of the fixing bolt B is accommodated in the concave portion 31c on the lower surface side of the slide member 31, the vertical rail 1 can be attached to the fixing bolt B with the nut N not screwed or loosened. The horizontal beam 2 can be easily temporarily assembled without hindrance, and the frame connecting bracket 3 is fastened and fixed to the horizontal beam 2 at two locations, and is also screwed to the vertical beam 1 on both sides. Both crosspieces 1 and 2 are rigidly and firmly connected, and a large connection strength is obtained.

  On the other hand, if the aluminum frame material is used for the vertical beam 1 and the horizontal beam 2 of the gantry frame 10 and the slide member 31 and the receiving member 32 of the frame connecting bracket 3 as in the embodiment, the entire gantry frame 10 is reduced in weight. In addition, there is an advantage that each can be mass-produced at low cost.

  In the photovoltaic power generation panel frame of the present invention, the vertical relationship between the vertical beam 1 and the horizontal beam 2 of the frame 10 may be opposite to that of the embodiment. For example, in the case where each photovoltaic power generation panel P is long in the front-rear direction, the number of arrangements in the inclination direction is reduced. Therefore, the horizontal rail 2 having a large number of bars so that each panel P can be supported at a plurality of locations. As the upper side, these horizontal rails 2 may be received by the vertical rails 1 arranged at intervals corresponding to the concrete foundations 4A and 4B, and supported by the concrete foundations 4A and 4B on the front side and the rear side of each vertical rail 1. Moreover, in this invention, the structure which provides a support | pillar also in the low front part side of the inclination mount frame 10, and supports and fixes the lower end part of this support | pillar to the concrete foundation 4A via the attachment bracket 7 similarly to a rear part side is also employable. . However, if the front side rail 2 is directly fixed to the mounting bracket 7 as in the embodiment, the lower front side is rigidly supported and fixed rigidly to the concrete foundation 4A. Can be prevented from collapsing even when subjected to wind pressure and damage and distortion are less likely to occur, and the number of members is reduced by not using a support on the front side, so that the assembly work becomes easier and the member cost is reduced. There is an advantage.

  On the other hand, the inclination angle of the gantry frame 10 is not limited to 10 ° exemplified in the above embodiment, and may be set as appropriate in consideration of the surrounding conditions of the installation location, the light receiving efficiency depending on the latitude, and the like. For example, FIG. 9A shows a photovoltaic power generation panel mount in which the inclination angle is set to 20 °, and FIG. 9B shows the inclination angle set to 30 °.

  Although the brace 8 on the rear side of the gantry frame 10 is not essential, the strength of the gantry structure is improved by providing this. Such a brace 8 may be provided over the entire length of the gantry frame 10 in the left-right direction. However, in the gantry frame 10 having a left-right length of three or more spans with the adjacent struts 6 and 6 as one span, the spans at both the left and right ends It is recommended to provide an X-shaped crossing in every other span or every other span. For example, when the gantry frame 10 has an odd number of spans of 3 or more, as shown in FIG. 10 (a), X-shaped braces 8 and 8 are provided in every other span including the left and right ends. Just do it. Further, when the gantry frame 10 has 4 spans, as shown in FIG. 10B, the 2 spans on the center side have no braces. As a result, the strength of the gantry structure can be ensured even if the number of the entire brace 8 is small, so that the member cost can be reduced by that much, and the construction efficiency can be greatly improved by reducing the number of mounting steps. is there.

  The foundation part on which the gantry frame 10 is installed is not limited to the concrete placing foundation or pile foundation such as the concrete foundations 4A and 4B illustrated above, but is a screw pile, a concrete foundation long in the left-right direction or the front-rear direction, and the roof of the building Various basic structures can be adopted according to the situation of the installation site, such as support brackets and mounting frames provided in the case. Furthermore, in the present invention, the cross-sectional shapes of the vertical beam 1 and the horizontal beam 2 of the gantry frame 10, the shapes of the slide member 31 and the receiving member 32 of the frame connecting bracket 3, the structure of the mounting bracket 7, and the photovoltaic power generation with respect to the support frame 10 Various design changes other than the embodiment can be made for the detailed configuration such as the fixing means of the panel P, the shape of the photovoltaic power generation panel P, and the number of arrays along the inclination direction.
