  Moreover, since the waterproof member 61 is arrange | positioned in the clearance gap between the insertion hole 15a and the connection part 33 of the mount leg 30, it is suitable for the roof of buildings, such as a factory and a warehouse where intrusion of rainwater etc. becomes a problem. Can be

  Moreover, it is a construction method of the solar panel mount 20 for attaching the solar panel 50 to the roof 10 on which the corrugated slate 15 is laid, a hole forming step of forming a plurality of insertion holes 15a in the corrugated slate 15, and a bottom plate portion A pedestal leg 30 having a base plate portion 32 and a connecting portion 33 that connects the bottom plate portion 31 and the top plate portion 32 is attached to the beam member 13 constituting the framework of the roof in the bottom plate portion 31. This is performed through an attachment process in which the top plate portion 32 is exposed from the roof 10 and a panel attachment step in which the holding body 40 holding the solar panel 50 is attached to the top plate portion 32. This construction method is suitable for repairing the existing roof 10.

  Moreover, if it carries out through an attachment process, a hole formation process, and a panel attachment process, it is suitable when constructing the roof 10 of a new building.

  Moreover, since the waterproofing process which arrange | positions the waterproof member 61 in the clearance gap between the insertion hole 15a of the waveform slate 15 and the mount leg 30 is performed after the attachment process and before the panel attachment process, intrusion of rainwater or the like It can be set as the construction method suitable for construction of the roof of buildings, such as a factory and a warehouse which become a problem.

  The solar panel mount 20 of the present invention is not limited to the above configuration. That is, various design changes can be made without departing from the gist of the present invention.

  For example, when constructing the roof 10 of a new building, the gantry leg 30 is attached to the beam member 13 constituting the framework of the roof 10 in the bottom plate portion 31 and the top plate portion 32 is exposed from the roof 10. The mounting step of arranging is performed first, and the hole forming step of forming a plurality of insertion holes 15a in the corrugated slate 15 and a plurality of insertion holes 16a in the base material 16 is performed later. Then, if a waterproofing process process and a panel attachment process are performed, the solar panel mount 20 can be constructed efficiently.
