Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting base for a solar cell panel and a method for assembling the mounting base.

[0002]

2. Description of the Related Art Conventionally, in this type of mount, square pipes are assembled in a grid pattern on mount supports scattered on the roof. That is, after arranging the lower square pipes in parallel with the girder row direction of the roof, the upper square pipes are arranged in parallel with the roof flow direction on these square pipes, and the orthogonal parts of the upper and lower square pipes are connected to the bolts and nuts. It was fixed.

[0003]

However, the mounting of the pedestal must be done on a roof with poor scaffolding, and since the square pipe is a long one, the lower square pipe is especially attached to the pedestal support. After mounting along the flow direction, when arranging the upper square pipe on the upper surface in a cross shape, the upper square pipe is slippery along the slope of the lower square pipe,
Unless multiple people support the upper square pipe, positioning and bolting are very difficult, time-consuming and time-consuming, and work efficiency is poor.

DISCLOSURE OF THE INVENTION In view of the above problems, the present invention has a support rod so that its tip is oriented in the longitudinal direction on the support rod after the support rod is arranged in parallel to the girder direction of the roof. By hooking the open bottom end of the panel mounting rod with a U-shaped cross section slidably on the hook-shaped projections provided at a predetermined interval above, the panel mounting rod is simply mounted on the inclined support rod. Just slide it in the length direction and it is stably arranged orthogonally. Then, the upper horizontal surface portion and the vertical surface portion which are continuously formed in a hook shape so as to correspond to the upper surface and the side surface of the panel mounting rod, respectively, and the upper surface and the vertical surface portion are formed so as to continuously contact the upper surface of the supporting rod member. An elastic fastener is used, which is composed of a lower horizontal surface portion and a hook portion provided by bending the tip of the upper horizontal surface portion downward so as to hook the open end of the upper surface of the panel mounting rod. Support the long panel mounting rod by hooking the tip of the hook on the lower part of the open upper end of the panel mounting rod and pressing the lower horizontal surface of the fastener so that it abuts the supporting rod. To solve the above problem, a fastener is attached to the crossing portion of the rod with one touch, and the lower horizontal surface portion is fixed to the support rod to form a pedestal.
