CONSTRUCTION METHOD OF COLUMN-BEAM SKELETON BY PRECAST CONCRETE MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a method of constructing a column-beam skeleton using a precast concrete column member and a precast concrete beam member. SOLUTION: A column-beam joint part joined to upper and lower precast concrete column members is formed as a column-beam joint part member integrating a beam part and manufactured as a precast concrete member, and a prestressed concrete steel is passed through the beam part in a material axis direction to form a precast prestressed concrete beam member with prestress led therein. The column-beam joint part and the precast concrete column member of the column-beam joint part member are butt-jointed when erecting at a site. The beam parts of the column-beam joint part member are jointed and integrated directly to each other or interposing a span center beam member between the beam parts while leading prestress into the prestressed concrete steel passing through in the axial direction of the beam members.
