Application manner null of steel-frame rigid frame structural

摘要

PURPOSE: To reduce outdoor work steps in a constructing site, solve a high-place work accompanying steel constructing work, and reconcile to automized construction by the united construction of a steel rigid-frame structure skeleton. ;CONSTITUTION: Table-shaped internal structure units 1 of one layer portion, which are vertically cut into a plane dimension of the same span in X- and Y-directions, are successively carried to a constructing floor and mutually connected thereon to construct an internal steel rigid-frame structure. Gate-shaped outer circumferential structure units 2 of one layer portion and one span are mutually connected so as to enclose the outer circumference of the internal steel rigid-frame structure, constructing an outer circumferential steel rigid-frame structure. Four connected divided columns 3a are mutually welded and integrated into a column 3, whereby a steel rigid-frame structure skeleton is constructed.;COPYRIGHT: (C)1993,JPO&Japio
