TOP SHEAVE DEVICE IN CLIMBING CONSTRUCTION METHOD OF ELEVATORS FOR WORK

摘要

PROBLEM TO BE SOLVED: To smoothly perform climbing of a top sheave by avoiding contact even in a member called a wall connector for joining guide posts to the skeleton side in a climbing construction method.;SOLUTION: This climbing construction method lifts a wire rope for connecting a carrier of elevators for work and a counterweight in response to progress of the work by winding the wire rope around the top sheave installed on the guide post. Device bodies 30 and 30 are liftably and fixably arranged along the guide posts 11 and 12. A frame 33 rotatably attached with the top sheave 31 is arranged in its device bodies. The frame 33 is slidably arranged on the side in the orthogonal direction to the rotary shaft direction of the top sheave 31. Thus, the top sheave 31 is movably constituted up to an outside position of the guide posts 11 and 12 when sliding so as not to contact with a support material 55 for fixing the guide posts 11 and 12 to a skeleton 54.;COPYRIGHT: (C)2007,JPO&INPIT
