PROBLEM TO BE SOLVED: To provide a substructure of a steel pipe pillar steel tower for the transmission of electric power which makes possible fine level adjustment by an anchor nut for installation adjustment, and makes possible easy level adjustment in a short time at the time of adjustment to the installation level of the steel pipe pillar steel tower for the transmission of electric power.;SOLUTION: The substructure is composed of a base plate 3 in the lowermost part, a plurality of anchor bolts 5, an anchor nut 6 for fixation, and an anchor nut 7 for installation and adjustment. The base plate 3 is provided in the lowermost part of the tower pillar 2 of the steel tower, and the plurality of anchor bolts 5 are buried in the base concrete 4 so that their tips which are projected from the base concrete 4 penetrate the base plate 3. The anchor nut for fixation is attached to the anchor bolt 5 on the top surface of the base plate 3, and the anchor nut 7 for installation and adjustment is attached to the anchor bolt on the undersurface of the base plate. A ring-shaped plate 12 is provided on the side of the anchor nut, and the ring-shaped plate has an engagement hole 11, or an engagement projection and an engagement concavity. The tip of a stick for the rotation of a nut which is inserted from a clearance between the foundation reinforcing bars 8 can be fixed by engagement.;COPYRIGHT: (C)2009,JPO&INPIT
