In the gantry frame 3 in which the upper-side vertical beam 1 is arranged so as to be inclined downward from the rear to the front, a plurality of photovoltaic panels P are arranged between the vertical beams 1 and 1 facing each other. A photovoltaic power generation panel base that is mounted in an array and is arranged with the upper vertical rails 1 and 1 being inclined downwardly from the rear side toward the front side, and overlapped perpendicularly to the lower side. The lower side crosspieces 2 and 2 are arranged in two places on the front side and the rear side in parallel along the direction, and among these, the front side crosspiece 2 is prismatic concrete through a short column 15A. The base 14A is arranged, and the rear side rail 2 is also cornered through a long column 15B. -Shaped concrete foundation 14B is arranged, whereby the upper vertical beam 1, 1 of the gantry frame 3 is supported on the upper surface of the lower horizontal beam 2, 2 and inclined downward from the rear side toward the front side. Are arranged. And the photovoltaic power generation panel P is inserted and arranged in a plane between the vertical bars 1 and 1. (In FIG. 1 (b), two photovoltaic power generation panels P in the front and rear are arranged in three horizontal rows between the four vertical bars 1 and 1, and a total of six photovoltaic power generation panels P are inserted and arranged.)

  In addition, although each photovoltaic power generation panel P is being fixed with the panel pressing spring 9 which is the principal part of this invention in the up-and-down and right-and-left end part, the detail is mentioned later.

As shown in FIG. 2, the upper vertical rails 1 and 1 are connected to each other by a frame connecting bracket 16 perpendicular to the upper surface of the lower horizontal rails 2 and 2. The photovoltaic power generation panel P is inserted and fixed through the panel pressing spring 9 toward the side.
That is, as shown in FIG. 3 which is an AA line enlarged cross-sectional view of FIG. 2, the upper-side vertical rail 1 arranged with a low inclination from the rear side toward the front side includes the left and right side pieces 4b, 4b is a hollow vertical beam main body 4 formed in a rectangular tube-shaped hollow portion 5 having a substantially rectangular shape longer than the upper surface piece (upper surface) 4a and the bottom piece 4c, and the upper surface 4a of the vertical beam main body 4 has the vertical A hollow spacer protrusion 6 having a vertically long hollow portion 6a communicating with the hollow portion 5 of the vertical beam main body 4 at the center of the upper surface of the vertical beam body 4 and protruding upward, A pair of spring engagement holding bases 7, 7 integrally formed in a plane shape in the longitudinal direction of the upper surface 4 a of the vertical beam body 4 with the spacer protrusion 6 in the center of the upper surface interposed therebetween, and a protruding end portion of the spacer protrusion 6 A pair formed integrally in a planar shape facing the pair of spring engagement holding bases 7 and 7 in the longitudinal direction across 6b Consisting panel top limit lug 8,8 Prefecture. A screw hole h for screwing the opening ends of the vertical beam main body 4 and the spacer protrusion 6 with a lid is appropriately formed on the inner wall side of the vertical beam main body 4 and the spacer projection 6.

  As shown in FIG. 3, a panel pressing spring 9 is engaged and held by the pair of spring engagement holding bases 7 formed with the spacer protrusion 6 interposed therebetween. Specifically, the panel pressing spring 9 is shown in FIG. In this manner, the spring engagement piece 17 projecting from one end of the spring engagement holding base 7 is engaged with the side face 6c of the base portion of the spacer protrusion 6 formed at the other end of the spring engagement holding base 7. And held on the spring engagement holder 7.

  As shown in FIGS. 4 and 5 (a) and 5 (b), the panel pressing spring 9 is curved in a flat downward U-shape in the longitudinal direction of the spring engagement holding base 7 as shown in FIGS. The control projection 10 is formed in a rectangular shape having a long side in the longitudinal direction, and a protrusion 10 is integrally projected on the curved top portion 9 a of the U-shaped curved surface of the panel pressing spring 9 perpendicular to the longitudinal direction. As an example, the length of the long side of the plane rectangular shape is 3 cm, the length of the short side is 1.8 cm, the thickness of the curved portion is 1 mm, and the restriction projection 10 is 1.5 mm.

  Thus, the panel pressing spring 9 uses the elastic deformation of the aluminum mold to fix the photovoltaic power generation panel P by its elastic force. And it is suitable for mass production by forming a large number of long aluminum molds formed by extrusion molding into, for example, 1.8 mm cut pieces with short sides in the above example, and these cut pieces have the exact same cross section. Since it has a shape, a plurality of photovoltaic power generation panels P can be fixed to the vertical beam 1 for a long time by the panel pressing spring 10 made of an aluminum mold material with a uniform pressing force without variation.

Since it is narrower than the thickness between the upper and lower surfaces, at the insertion end of the photovoltaic power generation panel P, as shown in FIG. 4, particularly FIG. The panel pressing spring 9 that is curved in the shape is pressed by the insertion end of the photovoltaic power generation panel P and elastically deforms in a slightly flat shape as shown by the chain line. A load is applied to the panel upper surface regulating flange 8 with which the upper surface of the panel P abuts, and by these actions, the photovoltaic power generation panel P is pressed and regulated by the panel pressing spring 9 and is automatically fixed between the two. And therefore simply Since the photovoltaic power generation panel P is sandwiched and fixed between the two by simply inserting the positive photovoltaic power generation panel P between the two, the photovoltaic power generation panel P can be very easily and easily disposed between the vertical beams 1 and 1. There is an advantage that it can be quickly and quickly mounted.

  Moreover, the vertical beam 1 is in the hollow vertical beam main body 4 and the upper piece 4a of the vertical beam main body 4, and communicates with the hollow part 5 of the vertical beam main body 4 at the center thereof so as to integrally project upward. It is composed of a hollow spacer projection 6 that is provided, and both form a reinforced hollow cross section having a large vertical width. Therefore, the load bearing force of the vertical beam 1 against the photovoltaic power generation panel P is large, and the photovoltaic power generation panel P from the outside is large. It can be strongly opposed to external force such as vibration against.

  In addition, the photovoltaic power generation panels P on both sides of the hollow spacer protrusion 6 integrally formed in the longitudinal direction of the vertical beam 1 are positioned and arranged in a certain space. The plurality of photovoltaic power generation panels P can be arranged such that the space spacing in the horizontal direction perpendicular to the longitudinal direction of the vertical rail 1 is accurately regulated by the hollow spacer protrusions 6.

  Further, as shown in FIGS. 5A and 5B, the panel pressing spring 9 curved in a flat downward U-shape engaged and held in the longitudinal direction by the pair of spring engagement holding bases 7 and 7. Is formed in a rectangle having a long side in the longitudinal direction in plan view, so that the panel pressing spring 9 can be stably provided on the spring engagement holding base 7, and the photovoltaic power generation panel P is Since it is inserted between the longitudinal bars 1 and 1 along the curved surface of the panel pressing spring 9 from the longitudinal direction, the insertion operation can be smoothly performed as much.

  Moreover, as shown in FIG. 2 or FIG. 4, the said control protrusion 10 formed in the panel pressing spring 9 protrudes from the back of the vertical rail 1 toward the front of the photovoltaic power generation panel P inserted one by one sequentially. The solar power generation panel P is brought into contact with the front and rear end faces P1 and P2 and is accurately positioned in the front-rear direction along the vertical rails 1 and 1 so that it does not unexpectedly change in the vertical direction along the vertical rails 1.

  Further, as shown in FIG. 4, a panel pressing spring 9 located between the longitudinal bars 1 and 1 that are arranged to face each other with a low inclination from the rear side to the front side is located at the foremost end of the vertical beam 1. Since the screw 11 is fixed to the spring engagement holding base 7, the photovoltaic power generation panel P positioned at the foremost end of the vertical rails 1, 1 is screwed with the panel pressing spring 9 at the foremost end to the spring engagement holding base 7. It is possible to prevent the front panel pressing spring 9 from serving as a retaining means together with the fixing means for the photovoltaic power generation panel P. Since it consists of a simple structure, it can be manufactured at low cost.

  Furthermore, as shown in FIG. 4, a panel pressing spring 9 located between the vertical bars 1 and 1 arranged to face each other with a low inclination from the rear side to the front side and located at the rearmost end of the vertical bar 1. Since the screw 12 is fixed to the spring engagement holding base 7, the photovoltaic power generation panel P located at the rearmost end of the vertical bars 1, 1 has the rearmost panel pressing spring 9 as the spring engagement holding base 7. It is possible to prevent the rear panel pressing spring 9 from serving as a retaining means together with the fixing means of the photovoltaic power generation panel P, by preventing the slipping off from the longitudinal bars 1 and 1 simply by fixing the screws 12. Since it has a simple configuration, it can be manufactured at low cost.

An insertion gap 13 that can be inserted between the pair of spring engagement holding bases 7, 7 between the pair and the pair of panel upper surface regulating flanges 8, 8 opposed thereto is provided between the vertical beam 1, 1 and the photovoltaic power generation panel P. It is provided between. In order to provide such an insertion gap 13, the insertion gap 13 is made wider by taking a wider insertion interval between the vertical bars 1, 1 shown in this embodiment than between the vertical bars 1, 1 shown in the embodiment. The clearance gap may be made wider than in the embodiment, but as shown in FIG. 7, the photovoltaic power generation panel P is a vertical beam from the lateral side perpendicular to the longitudinal direction of the vertical beam 1, 1 in an obtuse manner. An insertion gap 13 that can be inserted between the pair of spring engagement holding bases 7 and 7 between 1 and 1 and the pair of panel upper surface regulating flanges 8 and 8 opposed thereto is provided as a vertical beam 1 and 1 and photovoltaic power generation. In providing between the panel P, a hollow spacer column 8 provided perpendicularly between the pair of spring engagement holding bases 7 and 7 and the pair of panel upper surface regulating flanges 8 and 8 facing the pair. Is displaced to either the left or right side to hold the spring on one side 7 and an insertion gap 13 between the panel upper surface regulating flange 9 on the one side facing this, and the spring engagement holding base 7 on the other side and the panel upper surface regulating flange 9 on the other side opposed thereto. It is preferable to make the gap interval wider than the insertion gap 13.
