ERECTION ACCURACY ADJUSTING CONSTRUCTION METHOD FOR STEEL FRAMED STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide an erection accuracy adjusting construction method for steel framed structure easily executed, permitting simultaneous adjustment of span and verticality and facilitating fine adjustment to obtain high erection accuracy. ;SOLUTION: A large number of steel columns 12 and beams 16 are temporarily bolt- connected in a slidable manner through joint plates 18 into a frame. A partial block of the frame is made a reference block 24, and the columns 12 in the block 24 are adjusted in span and verticality by tensing a wire rope or the like. After obtaining erection accuracy, the columns 12 and the beam 16 in the reference block 24 are properly fixed. A laterally extensive jack 26 is disposed at the connection part of one end of the beam 16 connecting the column 22 of the reference block 24 to the adjacent column 12 in the temporarily fixed state. The respective extensive ends of the jack 26 are engaged with the connecting bolt insert-through holes of the beam 16 and a beam bracket 14 of the column 12 at the connection part. When the jack 26 is extended/contracted, a gap between the connection parts is extended/contracted taking reaction of the reference block 24 part, and the adjacent column is displaced to simultaneously adjust both span and verticality. After obtaining erection accuracy of the adjacent column, proper fixing is performed to enlarge the reference block 24 in order.;COPYRIGHT: (C)2000,JPO
