JOINT STRUCTURE OF CONCRETE MEMBER END

PROBLEM TO BE SOLVED: To provide a joint structure of a concrete member end capable of exhibiting superior structural performance and of reducing the fixing length of a concrete and a joining reinforcement. SOLUTION: In this joint structure of a concrete member end, a beam side U-part 12 which is adopted at the joint part T between a beam 1 and a column 2 which is formed of precast members and which is formed in U-shape by extending reinforcements 11 disposed in the concrete body 10 of the beam 1 in the axial direction E outward from the joint end surface 1a of the concrete body 10 and by connecting the ends of the reinforcements 11 to each other and joining reinforcements 21 projecting from the side surface 2a of the column 2 toward the axial direction E of the beam 1 are arranged while being overlapped with each other in the axial direction E. A non-adhering district R which does not adhere to the concrete is provided in the overlapped district of a part of the joining reinforcements 21 near the column 2. The beam side U-part 12 is disposed in the non-adhering district R, and the concrete 4 is deposited between the beam 1 and the column 2. COPYRIGHT: (C)2010,JPO&INPIT
