PROBLEM TO BE SOLVED: To simplify the marking work at installing a frame, when the frame is installed on a structure such as the roof of a house, and a solar energy utilization facility is fitted onto the frame. SOLUTION: This fitting frame is constituted so that leg fixing frames 33 and longitudinal frames 34 constituting the frame 31 are constructed out of pipes of square section, an upper face dovetail groove 37 and a side dovetail groove 38 are respectively formed on the upper face and the one side face of the leg fixing frame 33, side dovetail grooves 43 are formed on both sides of the longitudinal frame 34, the head parts of first bolts 51, second bolts 54, and third bolts 56 are respectively slidably fitted into the respective dovetail grooves 37, 38, 43, and the above-stated leg fixing frames 33 and the longitudinal frames 34 are combined together by these bolts, frame metal fixtures 49, and frame connecting metal fitting 53. At the marking work, it is enough to only draw two marking lines in parallel according to the positions of the leg fixing frames 33. |
