  In general, when a solar panel, for example, is installed as a functional panel on the roof surface of a building, it is desired that the number of solar panels installed on the roof surface is large in order to increase the total power generation amount. Therefore, for example, it is conceivable to spread the solar panels on the roof surface without gaps. On the other hand, the solar panel and the roof surface installed on the roof surface require regular maintenance, and if the solar panels are spread without gaps, the workability during maintenance deteriorates.

  An object of this invention is to provide the functional panel arrangement | positioning structure which can perform a maintenance suitably, installing many functional panels with respect to a roof surface.

  The functional panel arrangement structure of the present invention is a functional panel arrangement structure in which a plurality of panel rows formed by connecting a plurality of functional panels are arranged on a substantially flat roof, and between the plurality of panel rows. The end panel row which is at least one of the panel rows arranged at both ends is formed along the outer peripheral edge of the substantially flat roof, and the end panel row and the outer peripheral edge are arranged along the outer peripheral edge. The width between is smaller than the width of the passage.

  According to such a functional panel arrangement structure, the end panel row can be arranged close to the outer peripheral edge, so that the number of functional panels arranged on the roof surface can be increased. On the other hand, since the panel rows are arranged with a passage therebetween, the passages are provided adjacent to all the panel rows. Therefore, the worker can move the roof surface by walking along the passage. Therefore, maintenance can be suitably performed while installing many functional panels on the roof surface. In addition, when the functional panel is a functional panel that converts sunlight into electricity or heat, the panel rows are arranged with a passage between them, so the shadows of the front row functional panels located in the solar radiation direction are adjacent. It is possible to prevent the rear panel function panel from being applied.

  Moreover, the functional panel of the end panel row may be detachably attached to the substantially flat roof via an attachment portion that can be removed from the passage side. In this case, the functional panel can be attached to and detached from the end panel row only by the removing operation from the passage side.

  Moreover, the functional panel may be attached to the substantially flat roof via the mount. In this case, a plurality of functional panels can be arranged in an orderly and easy manner.

  Moreover, the attachment part is provided with the fastening part which fixes a function panel to a mount frame, and removal operation | movement may be the fastening operation | work of a fastening part. In this case, the functional panel can be fixed to the gantry with a relatively simple structure.

  Further, the substantially flat roof has a rectangular region, at least three sides of the rectangular region are arranged on the south side, the east side, and the west side, and a panel row group consisting of a plurality of panel rows corresponds to the rectangular region. The end panel row is arranged along the outer peripheral edge on the south side of the rectangular region, and at least one side edge and the outer peripheral edge of the rectangular region among the east side and west side edges of the panel row group. Between the two, a north-south passage communicating with the passage and extending in the north-south direction may be formed. According to this, even when a plurality of passages are formed, all the passages are connected to the north-south passage. Therefore, by passing through the north-south passage, it is possible to easily move from one passage to another passage.

  Moreover, the substantially flat roof may be provided with an elevating means that leads from the north-south passage to the downstairs and an installable structure for attaching the elevating means. Further, the lower end of the elevating means may be connected to a downstairs veranda or an empty space on the ground. Even when a plurality of passages are formed, all the passages can be easily accessed from the lifting means via the north-south passages.

  Further, at least one of the column bases that support the gantry may be disposed above the roof beam along the outer peripheral edge. By disposing the column base above the roof beam along the outer peripheral edge, the functional panel can be installed up to the outermost portion of the roof surface within the range where the center of gravity does not go out. Moreover, the load of a function panel is transmitted to a column base via a mount. Since the column base is disposed above the roof beam, the load received by the column base is transmitted to the lower roof beam. This eliminates the need for an auxiliary beam for receiving the column base, which is advantageous for weight reduction.

  In the above functional panel arrangement structure, the functional panel is rectangular, and the short sides of the plurality of functional panels are connected to form a panel row, or the long sides of the plurality of functional panels are connected to each other. A row may be formed.

  According to the functional panel arrangement structure of the present invention, maintenance can be suitably performed while installing many functional panels on the roof surface.
