CONNECTION STRUCTURE OF PRECAST CONCRETE BEAM END AND PRECAST CONCRETE BEAM COLUMN FRAME

摘要

PROBLEM TO BE SOLVED: To provide a connection structure of a precast concrete beam end, which has good workability, and a precast concrete beam column frame.SOLUTION: A connection structure 20 connects ends of a pair of precast concrete beams 21, 22 that butt against each other. The pair of precast concrete beams 21, 22 have thin concrete parts 23b, 24b, which protrude at lower side of the ends in butting direction, and lower end main reinforcements 27, 28, which extend in lengthwise direction in the thin concrete parts 23b, 24b, respectively. End faces of the thin concrete parts 23b, 24b are disposed so as to face each other. The connection structure comprises: an auxiliary reinforcement 31, which is disposed so as to stride the lower end main reinforcements 27, 28 of the pair of precast concrete beams 21, 22 above the thin concrete parts 23b, 24b along lower end main reinforcements 27, 28; and a concrete part, which is installed so as to embed the auxiliary reinforcement 31 between the pair of precast concrete beams 21, 22.SELECTED DRAWING: Figure 2
