<p>PROBLEM TO BE SOLVED: To provide a joint structure of deformed bars which can easily and firmly crimp a connection cylindrical member to deformed bars butted each other in a building site or factory, extremely quickly perform connection work of the deformed bars, and surely hold the deformed bars, even when a pair of projections formed into a half-split shape on peripheral surfaces of the deformed bars are formed at different positions in the lengthwise direction, and provide a formation method of the joint structure of the deformed bars.SOLUTION: A joint structure of deformed bars includes a cylindrical member which is attached to a butt part of two deformed bars formed with a plurality of projections with mutually-different pitches on both sides of the peripheral surfaces. Irregularities to be engaged with the projections of the deformed bars are formed on the inner peripheral surface of the cylindrical member and irregularities to be engaged with the projections of the deformed bars are formed on the outer peripheral surface of the cylindrical member.</p> |
