METHOD OF NON-ERECTION PIECE CONSTRUCTION AT TIME OF COLUMN STEEL-FRAMED ERECTION AND COLUMN STEEL-FRAMED ERECTION DEVICE THEREOF

摘要

PURPOSE: To shorten the term of works, and to reduce cost by a method wherein plumbing can be adjusted previously before erection, plumbing after erection is adjusted easily only by the slight fine adjustment of a small number of butt bolts, an erection piece is unnecessitated, and temporary tightening before plumbing adjustment is prevented while column welding is facilitated and post-treatment after column welding is unnecessitated completely. ;CONSTITUTION: A projection 5 for fitting is formed to one of horizontal plates 3, 4 arranged between the mutual joining sections of upper and lower column steel frames 1, 2 and a through-hole 6 for fitting, into which the projection 5 for fitting is inserted in an unturned manner, to the other. A plurality of butt bolts 7 abutted against the other peripheral section of the other are screwed at the proper places of one peripheral section, and the projection 5 for fitting and the through-hole 6 for fitting are fitted at the time of the erection of the steel frames while each butt bolt 7 is abutted against other horizontal plates 3, 4 and the horizontal plate 4 is placed on the horizontal plate 3. Plumbing is adjusted by each butt bolt 7, and the mutual joining sections are welded and unified.;COPYRIGHT: (C)1996,JPO
