Door framework unit and door framework attaching structure and door framework installation application manner

摘要

PURPOSE: To improve constructing performance by fixing a holding column, almost reaching a ceiling from a floor, rigidly to both side frame parts of a door frame, and fitting the upper and lower ends of the holding column to the ceiling and the floor face respectively in the position adjustable state. ;CONSTITUTION: A holding column 10 almost reaching a ceiling 2 from a floor 1 is fixed to both side parts 5a of a steel door frame 5, and a horizontal beam 11 is fixed to an upper frame part 5b respectively by welding. The upper end of the column 10 is fixed to the ceiling 2 by an upper end fixture 12, and the lower end of the column 10 is fixed to the floor 1 by an lower end fixture 13 respectively after position adjustment. Adjustment and fitting can be thereby performed simply omitting site-welding, in addition to dispensing with a wall body for fitting the door frame. The time and place restrictions of fitting work can be also reduced considerably, and the fitting position can be changed easily.;COPYRIGHT: (C)1993,JPO&Japio
