PURPOSE:To obtain a titled clamping device which executes easily the attaching and detaching work of a PC steel material and a PC steel material holding wedge, by constituting a PC steel material holding divided wedge supporting part and an insert- through part of a PC steel material in a temporary fixating piece, of a notch part which is provided in a row along the outside circumferential edge of the temporary fixation piece and is opened to the outside, respectively. CONSTITUTION:When fitting a temporary fixation piece 11 and a regular fixation piece 14 to PC steel material 15A, 15B groups to be strained and fixated, the steel materials 15A, 15B are install-racked on notch parts 12, 13 of said each piece from the outside of the fixation pieces 11, 14. Subsequently, divided wedges 16, 16' are fit-installed to the notch parts 12, 14. Subsequently, the steel material 15A is held through the divided wedge 16 by a notch part 13' of the piece 14, also the tip is held through a divided wedge 16' by notch part 13 of the piece 11, and the steel material 15B is inserted through the notch part 13 of the piece 11. Also, the tip of the steel material 15B is held by the notch part 12 of the piece 14 throgh the divided wedge 16, and the steel materials 15A, 15B are strained by expanding a jack 17 installed through between the pieces 11, 14. Subsequently, when a prescribed strain is completed, the jack 17 is loosened by making all the divided wedges 16 of the piece 14 gnaw in. |
