CONSTRUCTION OF LONG SPAN BEAM STRUCTURE

摘要

PURPOSE:To resist against a large span-load and deflection with a well balance, by hanging down PC steel rods from a column with a long spanned beam to the lower beam position of the lower body and firmly equipping a hydraulic jack on the beam right under the PC steel rods. CONSTITUTION:PC steel rods 19 are vertically arranged from the column position 17 of a long spanned beam 11 to the post position 18 at the upper side of a slab 15. And hydraulic jacks 20 are fixed on the upper post position 18 by anchor bolts 21. The lower edge of the PC steel rods 19 are connected to the jack rod 20a of the hydraulic jack 20 by use of a joint member 22. The reaction force on extending the PC steel rods 19 by use of hydraulic jacks can be treated by the lower body 14 through the lower posts under the hydraulic jacks.
