BOLT JOINT PART STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a bolt joint part structure for achieving effective fastening force without generating flexural yielding in a bolt by giving fastening force to the bolt along the axial direction of the bolt when repairing a steel material structure with bolt-nut joint even if a bolt abutting face is uneven with corrosion due to long-time use. SOLUTION: An unevenness correcting agent 2 constrained by a ring constraining member 15 is provided between a bolt washer 14 and a joined structure 100. The used unevenness correcting agent 2 is a curable cement mortar or resin or its mixture with inorganic particle or short fiber mixing agent. COPYRIGHT: (C)2006,JPO&NCIPI
