PRECAST CONCRETE COLUMN AND BEAM UNIT ASSEMBLING STRUCTURE BEING CONNECTED IN THE LOW BENDING MOMENT ZONE

摘要

PURPOSE: A prefabricated structure of a PC(precast) concrete column and a beam unit is provided to improve structural performance with respect to vertical and horizontal loads and to rapidly perform a task in high-altitude. CONSTITUTION: A PC concrete column and a beam unit joined in a low bending moment zone comprises an upper PC column(UC), a lower PC column(DC), a column re-bar(CB), a bracket member(110), lower bracket concrete(120), joint concrete(200), and a low bending moment joint material. The lower bracket concrete and joint concrete are integrally poured for pre-producing PC columns and beams for one unit or floor. The upper part of the upper PC column and the lower part of the lower PC column are positioned in the low bending moment zone. Both ends of the bracket member are positioned in a beam low bending moment zone(BLM).
