However, in general, a solar cell array is large and heavy with a short side number m and a long side number m to several tens of meters in which a plurality of photovoltaic power generation panels (solar cell modules) are arranged in a plane, and has a light receiving efficiency. Arranging at a predetermined inclination angle from the surface makes it easy to receive wind pressure and is also susceptible to shaking due to earthquakes, which requires a large structural strength, and also requires easy installation and cost reduction. .

  Conventionally, as a means for installing such a solar cell array on the ground or on a flat roof, the solar cell array is supported by a grid-shaped receiving frame in which a plurality of vertical beams (rafters) and horizontal beams (girder) are connected at crossovers. The support frame is supported at the main points of the lower side rails via posts or support posts and mounting brackets against the bases of concrete foundations and piles provided on the ground and flat roofs, and the bases of support fixtures provided on the roof of the building. The method of letting go is used a lot. For example, in the installation means disclosed in Patent Document 1, a plurality of support columns are protruded at intervals along the longitudinal direction (left-right direction) of the solar cell array, and the receiving frame that supports the photovoltaic power generation panel is inclined forward and backward. The upper end of each column is connected to an intermediate position of the vertical beam along the direction, and an inclined arm is connected between the trunk of each column and the front side or both front and rear sides of each vertical beam. Further, in the installation means disclosed in Patent Document 2, the receiving frame for supporting the photovoltaic power generation panel is supported by columns arranged in the front-rear and left-right directions, and oblique and horizontal reinforcing bars are disposed between the columns adjacent to the front-rear and left-right. Are connected.

The slide fitting 71 is slidably inserted into the guide groove 21 and cannot be detached from the upper side, and a fastening bolt B6 penetrating from the lower side of the slide fitting 71 protrudes upward, so that the front and rear photovoltaic panels P, P The presser fittings 72, which are arranged with the fixing bolts B6 between them and fitted into the fixing bolts B6, bridge over the edge frames F, F of the photovoltaic panels P, P, and from above the presser fittings 73. Both the solar power generation panels P and P are clamped and fixed between the presser fitting 73 and the receiving bar 2 by tightening the nut N6 screwed to the fixing bolt B6.

According to a sixth aspect of the present invention, in the photovoltaic power generation panel mount of the fifth aspect , the stopper member 8 for preventing the slide fitting 71 from being pulled out is fixed to the front end portion of the sliding guide groove 21 of the receiving bar 2. It is supposed to be.

Next, effects of the present invention will be described with reference numerals in the drawings. First, in the photovoltaic power generation panel stand according to the invention of claim 1, a plurality of photovoltaic power generation panels P are supported by a pair of left and right receiving rails 2 and 2 along the front-rear inclination direction, and each receiving rail 2 is attached to the front portion. Since the structure is supported by the support column 1A and the rear support column 1B, it is not necessary to connect the vertical beam and the horizontal beam at each crossing portion as in the conventional lattice-shaped receiving frame at the time of assembly. Therefore, a great deal of labor and time are saved, and the construction efficiency is dramatically improved. In addition to significantly reducing the weight of the upper part of the gantry compared to the case of using a lattice-shaped receiving frame, the weight of the front column 1A and the rear column 1B are relatively thin with relatively low support strength. Therefore, the overall weight of the gantry can be further reduced, and the cost of the members can be significantly reduced in combination with the omission of the cross rail and the connecting bracket in the lattice-shaped receiving frame. On the other hand, the strength of the structure as a photovoltaic power generation panel mount is such that the front braces 3A, 3A and the back braces 3B, 3B are constructed by crossing in an X shape between the front struts 1A, 1A and between the rear struts 1B, 1B. The side panels 4A and 4B installed between the middle portion of the receiving bar 2 on the left and right sides and the lower portions of the front column 1A and the rear column 1B allow the photovoltaic power generation panel P to be connected to the left and right receiving columns 2 and 2 only. Because it greatly improves beyond the compensation of the decrease due to the support, sufficient resistance to wind pressure and earthquake motion can be obtained.
In addition, according to the present invention, the front column 1A, the rear column 1B, and the receiving bar 2 are made of an aluminum mold having a substantially rectangular cross section, so that the entire gantry is lighter and stronger, and the front column 1A and the rear column Since the support 1B is fitted over the receiving bar 2 from below with the notch fitting part 11 on the upper end side, and the fitting part is connected by bolting, both the supports 1A, 1B and the receiving bar 2 can be easily connected. The construction efficiency can be improved more quickly, and the member cost can be further reduced by not using the connecting bracket.
Further, according to the present invention, when the front side of the receiving bar 2 extends longer than the support portion by the front column 1, the second portion is formed between the protruding portion 20 and the lower portion of the front column 1 </ b> A. Since the 3 side braces 4C are constructed, for example, by increasing the number of the front and rear arrays of the photovoltaic power generation panels P, sufficient structural strength can be ensured even if the overall length of the receiving beam 2 is increased.
In addition, according to the present invention, the side braces 4A to 4C use a hollow aluminum mold material having a substantially rectangular cross section, thereby enhancing the reinforcing effect as a brace, and the receiving rail 2 made of a hollow aluminum mold material having a substantially rectangular cross section. The two struts 1A and 1B are connected to the upper end side and the lower end side cutout fitting portions 42 and 43 so as to be bolted to facilitate the connection. In this case, the upper and lower sides of both struts 1A and 1B also receive the notch fitting portion 11 and receive the struts 2 so as to be bolted, and the left and right widths of the mold material are side braces 4A to 4C> both struts 1A and 1B> receiving struts. Therefore, when the opening widths of both the cutout fitting portions 42 and 43 of the side braces 4A to 4C are the same, the fitting portion between the cutout fitting portion 42 on the upper end side and the receiving bar 2 is rattled. . However, the side braces 4A to 4C have protrusions 41 and 41 that are continuous in the longitudinal direction on the opposing surfaces in the left and right direction on the inner surface side, and the protrusions 41 and 41 are provided on the left and right opposing walls 4b and 4b. The notch fitting part 42 on the lower end side, which is widened by cutting off the protrusions 41, 41 of the left and right opposing wall parts 4b, 4b, is provided on the receiving post 2 with the notch fitting part 42 on the upper end side having the front strut. Since it is straddled and bolted to 1A or the rear column 1B, both the upper end side and the lower end side can be firmly connected with no backlash.

According to the invention of claim 2 , the front strut 1A and the rear strut 1B are erected on the concrete foundations 5A and 5B via the anchor metal fittings 6, and the anchor metal fittings 6 are in relation to the concrete foundations 5A and 5B. Since it is possible to adjust the position in the front-rear direction within the range of the long hole 61 of the horizontal flat plate part 6a, the height of both struts 1A, 1B can be adjusted within the range of the long hole 62 of the vertical wall parts 6b, 6b of the anchor fitting 6. The installation position and elevation angle of the photovoltaic power generation panel P can be accurately set, and the position and panel angle corresponding to the ground subsidence after construction can be easily corrected.

According to the invention of claim 3 , the concrete foundations 5A, 5B are formed in a belt shape extending in the left-right direction on the front side and the rear side, respectively, and the front columns 1A, 1A are erected on the front side concrete foundation 5A. Since the rear columns 1B and 1B are erected on the concrete base 5B on the rear side, the front and rear positions and orientations of the pedestal are naturally determined, and the construction becomes easier, and the foundation side may be displaced with a heavy weight. In this case, the stability of the gantry is increased, and there is an advantage that it is easy to align the entire position and orientation when a plurality of the same photovoltaic panel gantry are installed side by side, particularly as mega solar or giga solar.

According to the invention of claim 4 , the anchor fitting 6 is integrally formed with the front strut 1 </ b> A or the rear strut 1 </ b> B in which the notch fitting portion 43 on the lower end side of the first and second side braces 4 </ b> A, 4 </ b> B is stretched. Therefore, there is an advantage that the efficiency of assembly work is further improved.

According to the invention of claim 5 , when the photovoltaic power generation panel P is mounted on the receiving rails 2 and 2, the slide fitting 71 in which the fastening bolt B <b> 6 is passed through the sliding guide groove 21 of the receiving rail 2 from below. The front and rear photovoltaic panels P, P are placed on the receiving side 2 with the fastening bolts B6 interposed therebetween, and the holding metal fittings 73 fitted into the fastening bolts B6 are mounted on the photovoltaic panels P. , P may be bridged between the edge frames F and F, and the nut N6 may be screwed and fastened to the fastening bolt B6 from above. Therefore, each photovoltaic power generation panel P can be efficiently fixed by a simple operation, and the fixing strength is large. For example, even if the solar power generation panel P is subjected to a large shaking during an earthquake or a large wind pressure during a strong wind, The load is received by the upper surface 2a of the receiving bar 2 through the slide fitting 71, and there is no concern that the slide fitting 71 will come off from the sliding guide groove 21 or that the fixing bolt B6 will be twisted or bent. Further, since the slide fitting 71 can move along the sliding guide groove 21 when the nut N6 is not screwed or loosened with respect to the fastening bolt B6, each photovoltaic power generation panel P placed on the receiving bar 2 is moved back and forth. Then, the entire arrangement of the photovoltaic power generation panel P can be set with high accuracy by screwing and tightening the nut N6.

According to the sixth aspect of the present invention, since the stopper member 8 that prevents the slide fitting 71 from being pulled out is fixed to the front end portion of the sliding guide groove 21 of the receiving bar 2 that is inclined downward and forward. When the power generation panel P is attached, the plurality of photovoltaic power generation panels P are sequentially moved from the front position to the front end and between each slide fitting 71 while the nut N6 is not screwed or loosened with respect to the fixing bolt B6. It can be efficiently arranged in such a manner that it is placed on the receiving bar 2 with the slide fitting 71 interposed therebetween, and is slid along the inclination and packed forward.

  Hereinafter, an embodiment of a photovoltaic power generation panel mount according to the present invention will be specifically described with reference to the drawings.

  The photovoltaic power generation panel mount according to the first embodiment shown in FIGS. 1 to 3 has a pair of left and right lower front columns 1A, 1A on the front side concrete foundation 5A extending in the left-right direction, and the same rear side. On the concrete foundation 5B, a pair of left and right high rear columns 1B, 1B are erected vertically via anchor fittings 6, respectively, and a pair of left and right receiving bars 2, 2 are supported by the front column 1A and the rear column 1B, respectively. A plurality of (five in the figure) rectangular solar power generation panels P that are long in the left-right direction are mounted on both receiving rails 2 and 2 in a planar arrangement in the front-rear direction. Yes. The front braces 3A and 3A are laid between the left and right front struts 1A and 1A, and the back braces 3B and 3B are respectively erected between the left and right rear struts 1B and 1B. On both the left and right sides, a first side brace 4A is provided between the intermediate part of the receiving bar 2 and the lower part of the front column 1A, and a second side brace 4B is provided between the intermediate part of the receiving bar 2 and the lower part of the rear column 1B. Are built. The inclination angle of the illustrated receiving bar 2 is set to 10 °.

  Here, the front support column 1A and the rear support column 1B have the same hollow aluminum mold material having a substantially square cross section, the receiving bar 2 has a substantially vertical rectangular hollow aluminum mold material, and the front brace 3A and the back brace 3B have FIG. A hollow aluminum mold material Q having a substantially square cross section as shown in (a) is a hollow aluminum mold material having a substantially square cross section in the first and second side braces 4A and 4B slightly thicker than both struts 1A and 1B. Are used respectively.

  Since the front and rear struts 1A and 1B in the front and rear side concrete foundations 5A and 5B have the same standing structure, they will be described with reference to the front side in FIGS. . First, both concrete foundations 5A and 5B are embedded and fixed in a lower hole 51 vertically drilled from the top surface with an anchor bolt B1 protruding partly upward through a resin binder R. The anchor metal fitting 6 is made of a short cut material of an aluminum mold, and has an elongated hole 62 in the vertical direction and an upper screw in the other half of the horizontal plate portion 6a having a longitudinal hole 61 in the longitudinal direction on one side half. A pair of vertical wall portions 6b, 6b having an insertion hole 63 and extending in the front-rear direction are integrally erected, and a horizontal plate portion 6a is placed on the top surfaces of the concrete foundations 5A, 5B. The nut N1 is screwed and fastened to the anchor bolt B1 passed through 61 through the plain washer W1 and the spring washer W2, so that the position can be adjusted in the longitudinal direction within the range of the long hole 61 to the concrete foundations 5A and 5B. Has been.

  The front and rear struts 1A and 1B are fitted with anchor fittings at the lower ends of the first and second side braces 4A and 4B. 6 is fitted between the vertical wall portions 6b and 6b, and the nuts N2 are fastened to the mounting bolts B2 passed through the long holes 62 and 62 of the vertical wall portions 6b and 6b. By being fixed so that the position can be adjusted in the vertical direction within the range of the long hole 62, the drilling tapping screw S is screwed from the outside through the screw insertion holes 63 of the vertical wall portions 6b, 6b of the anchor fitting 6 at the adjustment position. It is fixed to a predetermined height. Note that a plain washer W1 is interposed on the head side of the mounting bolt B2, and a plain washer W1 and a spring washer W2 are interposed on the nut N2 side. The interposition of these washers W1 and W2 is the same in other bolting portions. Therefore, the description is omitted hereinafter.

  The front brace 3A and the back brace 3B, as representatively shown in the lower part on the front side in FIGS. 4 (a) and 4 (b), respectively, on the upper and lower parts of the front strut 1A or the rear strut 1B at both upper and lower ends, It is connected by a mounting bolt B4 and a nut N4 that are passed through the central space portion of the cross section of the eye shape.

  As shown in FIGS. 5 (a) and 5 (b), the upper ends of the front and rear struts 1A and 1B have notch fitting portions 11 formed by cutting away the front and rear facing wall portions 1a and 1a. The mating portion 11 is connected to the receiving beam 2 by bolting a fitting portion straddling the receiving beam 2 from below with a through bolt B3 and a nut N3. The receiving bar 1 is provided with a sliding guide groove 21 continuous in the longitudinal direction on the upper surface, and a locking groove 22 continuous in the longitudinal direction is formed at the upper part of the both side surfaces 2b. It is divided vertically by the partition wall 23 of the position. And the penetration bolt B3 which connects the upper end side of both support | pillars 1A and 1B has penetrated the lower part side rather than the partition wall 23 of the receiving crosspiece 1. FIG.

  As shown in FIGS. 6 (a) and 6 (b), the upper end sides of the first and second side braces 4A and 4B receive the notch fitting portions 42 as shown in FIGS. 6 (a) and 6 (b). The fitting part straddled from below is bolted with a through bolt B5 and a nut N5 so as to be connected to the lower side of the partition wall 23 of the receiving bar 2.

  7A to 7C show the first side brace 4A, and FIGS. 8A to 8C show the second side brace 4B. That is, the first and second side braces 4A and 4B are made of the same hollow aluminum mold having a substantially square cross section, and have protrusions 41 and 41 that are continuous in the longitudinal direction on opposite surfaces on the inner surface side in the left-right direction. The notch fitting portions 42 and 43 are formed by cutting away the front and rear facing wall portions 4a and 4a on the upper end side and the lower end side. Of these, the notch fitting portion 42 on the upper end side leaves the protrusions 41 and 41 inside the left and right opposing wall portions 4b and 4b on both sides, whereas the notch fitting portion 43 on the lower end side has left and right opposing walls on both sides. The opening width is widened by cutting up the protrusions 41 and 41 of the parts 4b and 4b. That is, the opening width of the notch fitting portion 42 on the upper end side corresponds to the left and right width of the receiving bar 2, and the opening width of the notch fitting portion 43 on the lower end side corresponds to the left and right widths of the front column 1A and the rear column 1B. Thus, rattling is not generated in each straddle portion by the both notch fitting portions 42 and 43.

  That is, both side braces 4A and 4B need to be wider (thicker) left and right than both struts 1A and 1B for straddling the notch fitting portion 43 on the lower end side, but both struts 1A and 1B are also on the upper end side.

Therefore, if the notch fitting part 42 on the upper end side and the notch fitting part 43 on the lower end side of the both side braces 4A and 4B have the same opening width, the notch fitting part 43 on the lower end side is suitable for both struts 1A and 1B. Even if fitted, the notch fitting portion 42 on the upper end side with respect to the receiving bar 2 having a narrower left and right width creates a gap and becomes loose. On the other hand, a simple rectangular tube having no protrusions 41, 41 is used, and the notch fitting portion 43 on the lower end side is constituted only by the left and right opposing wall portions 4b, 4b, and the notch fitting portion 42 on the upper end side is front and rear. The opening width can be narrowed by leaving a part of both sides of the opposing wall portions 4a, 4a, but in this case, only the side edge portions on the receiving rail 2 with the notch fitting portion 42 on the upper end side straddled. Since it comes in contact, it will not be in a strong connected state. However, as in the embodiment, on the inner side of the left and right opposing wall portions 4b and 4b of the both side braces 4A and 4B, the ridge portion 41 having a height corresponding to the difference between the left and right widths of the two columns 1A and 1B and the receiving bar 2 is provided. , 41, the notch fitting part 43 on the lower end side is brought into contact with both struts 1A, 1B on the entire inner surfaces of the left and right opposing wall parts 4b, 4b, and the receiving bar is provided on the notch fitting part 42 on the upper end side. 2 can be brought into contact with the protrusions 41 and 41 and part of both sides of the front and rear opposing wall portions 4a and 4a, and both can be brought into a firm connection state.

  Note that the first side brace 4A and the second side brace 4B have the same alignment angle with respect to the receiving bar 2 and both struts 1A and 1B. The inclination is different as shown in FIGS. Further, a small-diameter bolt insertion hole 45 is formed in the notch fitting portion 42 on the upper end side of the braces 4A and 4B on both sides, and a large-diameter bolt insertion hole 46 is provided in the notch fitting portion 43 on the lower end side.

  As shown in FIGS. 9 and 12, the holding metal fitting 73 is used to fix the photovoltaic power generation panel P at the intermediate portion in the front-rear direction of the receiving bar 2, and is a substantially square plate-shaped aluminum extrusion mold material. It is made of a short cut material and is provided with engaging pieces 73a having a reverse L-shaped longitudinal section on both side edges. Further, as shown in FIGS. 9 and 12, the end pressing metal fitting 9 is used to fix the end portions of the photovoltaic power generation panel P at the front and rear end portions of the receiving bar 2. In the same manner as above, it is made of a short cut material of an aluminum extrusion mold material, and includes an engagement piece 90a having a vertical L-shaped cross section on one side edge of the rectangular substrate part 90, but on the other side edge of the substrate part 90 A side cover portion 91 having a vertical cross-sectional shape is suspended. In addition, although illustration is abbreviate | omitted, the bolt insertion hole is drilled in the presser metal fitting 73 and the edge part presser metal fitting 9.

  The spacer metal fitting 72 is made of a short cut material of an aluminum extrusion mold material having a downwardly open U-shaped frame shape, and has a bolt insertion hole 72e in the upper plate portion 72a as shown in FIGS. A locking claw 72c that protrudes inward at the lower end and a protruding piece 72d that protrudes inward at the middle are formed on the pieces 72b and 72b. The spacer metal 72 is engaged with the locking grooves 22 and 22 on both sides of the receiving bar 2 while the both locking claws 72c and 72c are received, and both protruding pieces 72d and 72d are placed on the upper surfaces 2a and 2a of the receiving bar 2. In this manner, the receiving bar 2 is set so as to be slidably fitted so as not to be separated upward.

  As shown in FIG. 10 (b), the slide fitting 71, the fastening bolt B5, and the spacer fitting 72 are fastened from below to the slide fitting 71 and both bolt insertion holes 71d and 72e of the spacer fitting 71 arranged on the upper side thereof. In a state where the bolt B6 is penetrated, the slide fitting 71 is inserted into the sliding guide groove 21 of the receiving beam 2 and at the same time, the spacer fitting 72 is slid into the receiving beam 2. As a result, the fastening bolt B6 is stably held upright from the slide fitting 71, and the upper plate portion 72a of the spacer fitting 72 is also stably held at a constant height from the vertical rail 1.

  On the other hand, as shown in FIGS. 9 and 12, at the front end portion of the receiving bar 2 inclined to the front, a stopper member 8 made of a metal plate bent in an L shape is formed on the bottom surface of the front end of the sliding guide groove 21. It is fixed by a drilling tapping screw S. As a result, the slide fitting 71 fitted in the slide guide groove 21 is prevented from dropping forward from the slide guide groove 21 by the leg piece portion 71b coming into contact with the stopper member 8. .

  In order to mount the photovoltaic power generation panel P on the receiving bar 2, the required number of the slide fittings 71 in which the fixing bolts B <b> 6 and the spacer fittings 72 are assembled in the sliding guide grooves 21 of the receiving bars 2 as described above, that is, The number of photovoltaic power generation panels P to be arranged in the front-rear direction plus one (six if the number of photovoltaic power generation panels P is five as shown in FIGS. 1 and 2) is inserted and placed on the receiving rail 2 The required number of photovoltaic power generation panels P are sequentially placed from the front row side with the slide fittings 21 interposed between the front and rear ends and each other. At this time, since the slide fitting 71 at the foremost end inserted into the sliding guide groove 21 of the receiving bar 2 stops in contact with the stopper member 8, a plurality of photovoltaic panels P are attached to the receiving bar 2. It can be arranged efficiently by sliding along the slope and packing it forward.

  Then, as shown in FIG. 9, in the middle portion of the receiving bar 2, the opposite side surfaces of the edge frames F, F of the photovoltaic power generation panels P, P adjacent to the front and rear abut against the spacer metal fitting 72 assembled to the slide metal fitting 71. In this state, the holding metal fitting 73 is fitted to the fastening bolt B6 protruding from the slide metal fitting 71, and both engaging pieces 73a, 73a of the holding metal fitting 73 are arranged inside the edge frames F, F on both sides, respectively. In this state, the nuts N6 are screwed and tightened to the fastening bolts B6 via the plain washers W1 and the spring washers W2, so that the solar panels P, P can be connected between the presser fitting 73 and the receiving bar 2. The edge frames F and F are clamped and fixed. Similarly, at the front and rear ends of the receiving bar 2, the fastening bolt B 6 is attached to the fastening bolt B 6 with the front side surface or rear side surface of the edge frame F of the photovoltaic power generation panel P at the end position in contact with the spacer metal fitting 72. The end holding metal fitting 9 is fitted so that the engaging piece 90a side faces the photovoltaic power generation panel P side, and a nut N6 is screwed onto the fastening bolt B6 from above and tightened, whereby the holding metal fitting 9 and the receiving bar are attached. The edge frame F of both photovoltaic power generation panels P is clamped and fixed between the two. In addition, in this front-and-rear end part, as shown in FIG.9 and FIG.12, the shaft part of the fixing bolt B6 and the spacer metal fitting 72 are concealed from the side by the side cover part 91 of the presser fitting 9, thereby The front and rear appearances of the power generation panel mount are improved.

  In the photovoltaic panel base having the above-described configuration, a plurality of photovoltaic panels P are supported by a pair of left and right receiving bars 2 and 2 along the front-rear tilt direction, and each receiving bar 2 is supported by a front column 1A and a rear column 1B. Therefore, it is not necessary to connect the vertical beam and the horizontal beam at each crossing portion as in the conventional grid-shaped receiving frame during assembly work, and a great amount of labor and time for the connection can be saved. As a result, construction efficiency is dramatically improved. In addition to significantly reducing the weight of the upper part of the gantry compared to the case of using a lattice-shaped receiving frame, the weight of the front column 1A and the rear column 1B are relatively thin with relatively low support strength. Therefore, the overall weight of the gantry can be further reduced, and the cost of the members can be significantly reduced in combination with the omission of the cross rail and the connecting bracket in the lattice-shaped receiving frame. On the other hand, the strength of the structure as a photovoltaic power generation panel mount is such that the front braces 3A, 3A and the back braces 3B, 3B are constructed by crossing in an X shape between the front struts 1A, 1A and between the rear struts 1B, 1B. In addition, four support pillars 1A, 1A, 1B, 1B and left and right supports are provided by side braces 4A, 4B installed between the middle part of the receiving bar 2 on the left and right sides and the lower part of the front support post 1A and the rear support post 1B. Since the piers 2 and 2 are firmly connected to each other and integrated, the solar power generation panel P is greatly improved by overcoming the decrease due to being supported only by the left and right receiving piers 2 and 2, and against wind pressure and earthquake motion. Sufficient tolerance is obtained.

  In particular, in the configuration of the embodiment, since the front column 1A, the rear column 1B, and the receiving bar 2 are made of an aluminum mold having a substantially rectangular cross section, the entire gantry is lighter and stronger, and the front column 1A and the rear column 1B has a notch fitting portion 11 on the upper end side and is fitted over the crosspiece 2 from below, and the fitting portion is connected with a bolt, so that the connection between the support posts 1A, 1B and the reception crosspiece 2 can be easily and quickly performed. Therefore, there is an advantage that the construction efficiency is further improved, and the member cost is further reduced by not using the connecting metal fitting. In addition, the front support column 1A and the rear support column 1B are erected on the concrete foundations 5A and 5B via the anchor fittings 6. In particular, according to the anchor fittings 6 used in the embodiment, the concrete foundations 5A and 5B As a result, it is possible to adjust the position in the front-rear direction within the range of the long hole 61 of the horizontal plate portion 6a, and to adjust the height of both struts 1A, 1B within the range of the long hole 62 of the vertical wall portions 6b, 6b of the anchor fitting 6. There is an advantage that the installation position and elevation angle of the photovoltaic power generation panel P can be set with high accuracy, and the position and panel angle corresponding to the ground subsidence after construction can be easily corrected.

  On the other hand, on the foundation side of the gantry, an independent foundation-type concrete block can be used for each column, but it is formed in a strip shape extending in the left-right direction on the front side and the rear side as in the above embodiment. If the concrete foundations 5A and 5B are employed, the front struts 1A and 1A are erected on the front concrete foundation 5A, and the rear struts 1B and 1B are erected on the rear concrete foundation 5B. The front / rear position and orientation of the pedestal are naturally determined, and the installation is easier, and there is no concern of the foundation side being displaced by heavy weight, so the stability of the pedestal also increases. Especially, the same photovoltaic panel gantry as mega solar or giga solar There is an advantage that it is easy to align the whole position and orientation when arranging a plurality of these in parallel.

  Further, as for the first and second side braces 4A and 4B, a flat hollow aluminum mold material may be used as in the case of the front brace 3A and the back brace 3B. In order to enhance the reinforcing effect in the longitudinal direction, the receiving bar 2 and both struts 1A are formed by the cut-off fitting portions 42 and 43 on the upper end side and the lower end side in order to enhance the longitudinal reinforcing effect. , 1B, that is, it is preferable to use one having a lateral width larger than both struts 1A, 1B. And, as in the embodiment, if it is straddled on the receiving bar 2 and both struts 1A, 1B at the notch fitting portions 42, 43 on the upper end side and the lower end side, and bolted at the fitting portion, The connecting operation can be performed easily and efficiently. Further, as in the embodiment, if the notch fitting portion 43 on the lower end side is bolted to the strut 1A or the rear strut 1B integrally with the anchor bracket 6 via an anchor fitting 6, There is an advantage that the efficiency is further improved.

  In the first embodiment, the first and second side braces 4A and 4B are used on each of the left and right sides. When the overall length of 2 is increased, a side brace is further added between the front overhanging portion of the receiving beam 2 and the front column 1A, and between the rear protruding portion of the receiving beam 2 and the rear column 1B. It may be erected. For example, in the photovoltaic power generation panel stand of the second embodiment shown in FIG. 13, the front side of the receiving bar 2 is ahead of the support portion by the front support column 1A in order to arrange the six photovoltaic power generation panels P back and forth. A third side brace made of a hollow aluminum mold having a substantially square cross section similar to that of the first and second side braces 4A and 4B, between the overhang portion 20 and the lower portion of the front column 1A. 4C is installed, and this ensures sufficient structural strength. Although the detailed illustration of the upper end side and the lower end side of the third side brace 4C is omitted, the receiving bar 2 is used as a notch fitting portion similar to the first and second side braces 4A and 4B. And it bolts by straddling the front support column 1A.

  On the other hand, in the configuration of the embodiment, when the photovoltaic power generation panel P is mounted on the receiving rails 2 and 2, the slide fitting 71 in which the fastening bolt B <b> 6 is penetrated from below into the sliding guide groove 21 of the receiving rail 2. Inserting and placing the front and rear photovoltaic panels P, P on the receiving side 2 with the fastening bolts B6 sandwiched between them, the holding metal fittings 73 fitted into the fastening bolts B6 are mounted on the two photovoltaic panels P, Since it is only necessary to bridge between the edge frames F and F of P and to fasten and fasten the nut N6 to the fastening bolt B6 from above, each photovoltaic power generation panel P can be efficiently fixed by a simple operation. Moreover, even if the fixed strength is large, for example, even when the solar power generation panel P is subjected to a large shaking during an earthquake or a large wind pressure during a strong wind, the load is applied to both side edges of the sliding guide groove 21 via the slide fitting 71. There is no concern that the slide fitting 71 is detached from the slide guide groove 21 and the fastening bolt B6 is twisted or bent. Further, since the slide fitting 71 can move along the sliding guide groove 21 when the nut N6 is not screwed or loosened with respect to the fastening bolt B6, each photovoltaic power generation panel P placed on the receiving bar 2 is moved back and forth. By positioning the nut N6 and tightening the nut N6, there is an advantage that the entire arrangement of the photovoltaic power generation panel P can be set with high accuracy.

  Furthermore, if it is set as the structure which fastens the stopper member 8 which prevents extraction of the slide metal fitting 71 to the front-end part of the sliding guide groove 21 of the receiving rail 2 inclined low like the front like Embodiment, it is sunlight. When the power generation panel P is attached, the plurality of photovoltaic power generation panels P are sequentially moved from the front position to the front end and between each slide fitting 71 while the nut N6 is not screwed or loosened with respect to the fixing bolt B6. It can be efficiently arranged in such a manner that it is placed on the receiving bar 2 with the slide fitting 71 interposed therebetween, and is slid along the inclination and packed forward. In addition, since the spacer metal fitting 72 is fitted to the fastening bolt B6 as in the embodiment, the spacer metal fitting 72 can be sandwiched and positioned between the adjacent photovoltaic power generation panels P and P. The position of each photovoltaic power generation panel P can be set more easily and accurately.

  The inclination angle of the receiving bar 2 in the photovoltaic power generation panel mount of the present invention 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. Furthermore, in the present invention, the cross-sectional shapes of the front and rear struts 1A and 1B, the receiving bar 2, the front and back braces 3A and 3B, the first to third side braces 4A to 4C, and the shape of the anchor fitting 6 In addition to the embodiment, various modifications can be made to the detailed configuration such as the shape of the slide fitting 71, the holding fitting 73, the end holding fitting 9, the shape and the number of the photovoltaic power generation panels P, and the like.
