FLOOR PORTION CONNECTING METHOD OF A PRECAST CONCRETE COLUMN USING HEAD STEEL BARS CAPABLE OF IMPROVING QUAKE-RESISTANCE PERFORMANCE

摘要

PURPOSE: A floor portion connecting method of a precast concrete column using head steel bars is provided to improve the construction processes effectively and economically through head steel bars.;CONSTITUTION: A floor portion connecting method of a precast concrete column using head steel bars is composed as follows. Some portion of a main bar is exposed to cope with the length of the joint of the mid-portion between floors and the other portion is cut. The main bars exposed on an upper column and a lower column are arranged not to be overlapped(S10). The upper column and the lower column are arranged in a joining portion and attached to the end portion of a column(S20). The exposed main bar is fastened through a shear reinforcement bar(S30).
