The support metal fitting 14 has a through hole 32 that allows the plate material of the leg portion 30 to penetrate in the thickness direction and allows the leg plate surfaces to communicate with each other. In the state where the leg portion 30 with the through hole 32 is embedded in the height support portion 22 formed of concrete, the inside of the through hole 32 and both plate surfaces and their outer portions are supported integrally with the concrete. The holding structure 34 is configured by integrating the metal fitting 14 and the height support portion 22. The support fitting 14 is received by the photovoltaic power generation panel frame by the leg 30 itself constituting anchor means, and by integrally bonding the concrete on the both sides of the leg through the through holes 32 in the holding structure 34. The fixed state of the support fitting 14 and the support base 12 is firmly held against the pulling force.

  In the present embodiment, as shown in FIGS. 2, 6, and 7, the support fitting 14 includes, for example, an inverted L-shaped member 36 whose cross section perpendicular to the longitudinal direction is an inverted L shape. The inverted L-shaped member 36 is provided, for example, by bending a long metal plate on one side in an L-shape when viewed from the end, and the horizontal plate portion of the inverted L shape in the horizontal direction becomes the engaging portion 28, and the horizontal plate portion A side plate portion in the vertical direction bent substantially perpendicularly from the side becomes the leg portion 30. The leg portion 30 is provided with a plurality of through holes 32 at regular intervals along the longitudinal direction of the leg portion at a lower portion of the leg portion. As shown in FIG. 5, each through hole 30 is, for example, a circular hole having a diameter that is approximately half the length of the leg portion in the vertical direction, and is formed with a certain wide area. . In other words, the concrete is filled into the through holes 32 of the leg portions 30 and is integrally coupled to strengthen the connection strength.

For example, the connecting portion 38 is composed of a plurality of plate-like members 39 that are arranged with their plate surfaces vertically arranged so as to be narrow in plan view, and whose both ends are connected to the leg portions 30 of the support fitting 14 by spot welding. These plate-like members 39 are juxtaposed at predetermined intervals along the longitudinal direction of the support fitting 14. Basically, the structure of the connecting portion 38 may be arbitrary. For example, if the connecting portion is formed with a large area in plan view, there is a possibility that air may remain between the connecting portion and the concrete forming the height supporting portion. is there. If air enters the concrete structure, the structure will be weakened and prematurely damaged. As in this embodiment, by providing the connecting portion with a narrow member in plan view, air is prevented from accumulating between the connecting portion and the concrete of the height supporting portion, and a strong integrated connecting structure is achieved. realizable. The connecting portion may be a rod-shaped member such as a thin round steel. Moreover, the connection part 38 is not necessarily required, For example, it is good also as holding | maintaining the opposing gap | interval of the two support metal fittings 14 opposingly arranged by a formwork or other arbitrary means.

It is a connecting means for connecting the support fitting 14 and the frame 18 at an arbitrary position in the longitudinal direction of the support fitting 14. In the present embodiment, the coupling device 16 includes, for example, a bracket 40 as a stopper that receives the frame 18 at a predetermined inclination angle, and fastening members 42 and 44 made of bolts and nuts. The bracket 40 is formed, for example, by bending a metal plate into a predetermined shape, and includes a rectangular bottom plate portion 401 and two vertical support plate portions 402 that rise at different heights from a pair of opposing sides of the bottom plate portion 401. In addition, an inclined receiving plate portion 403 that is inclined in accordance with the inclination angle of the frame 18 from the upper end of each vertical support plate portion 402 is integrally provided. The inclination receiving plate portion 403 is set to an inclination angle (for example, 20 to 30 degrees) corresponding to the inclination angle for setting the frame 18. The inclined receiving plate portion 403 is provided with a bolt hole, and is aligned with the bolt hole provided in the frame 18 and connected by the fastening member 44. A bolt hole is provided in the bottom plate portion 401 of the bracket 40, and the bottom plate portion 401 of the bracket and the support fitting 14 are connected via a fastening member 42. The fastening member 42 is engaged with the engagement portion 28 in a state where the enlarged base portion of the bolt is accommodated in the groove portion 31 between the support fittings 14 constituting the guide gap 26 of the rail portion, and the screw shaft is slit. 29 is arranged to penetrate. A bolt hole of the bottom plate portion 401 of the bracket 40 is passed through a portion of the bolt that protrudes upward from the slit, and is fastened with a nut to be connected to the support fitting 14.
