JOINING STRUCTURE AND JOINING METHOD OF COLUMN-BEAM JOINT MEMBER AND COLUMN MEMBER OF PRECAST CONCRETE CONSTRUCTION

PROBLEM TO BE SOLVED: To easily join a column-beam joint member and a column member of precast concrete construction. SOLUTION: The column-beam joint member 3 of precast concrete construction is provided with through-holes 6 formed in concrete 7 of the column-beam joint member 3. A plurality of shaft reinforcements 8 and circular spiral reinforcements 9 surrounding the shaft reinforcements 8 are disposed in the concrete 7 formed with the through-holes 6. Column main reinforcements 4 projected from an upper end 1a and a lower end 1b of the column member 1 are inserted in the through-holes 6 from the upper side and lower side of the through-holes 6, and grout 12 is filled in air gap parts between the column main reinforcements 4 and the through-holes 6. The grout 12 is hardened to join the column-beam joint member 3 and the column member 1. COPYRIGHT: (C)2010,JPO&INPIT
