CRACK INDUCING JOINT MEMBER, CRACK INDUCING STRUCTURE AND CONSTRUCTION METHOD OF CONCRETE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a crack inducing joint member capable of surely generating a crack in a desired position, a crack inducing structure and a construction method of a concrete structure.;SOLUTION: This crack inducing joint member 10 is provided for generating the crack in a desired place of the concrete structure 1, and has a long size joint part 11 fixed to an inside surface of a face plate 3a for a form 3, a plurality of shaft fastening members 12 juxtaposed at a predetermined interval in the longitudinal direction of this joint part 11 on a reverse surface of this joint part 11, a plurality of projecting shaft parts 13 projectingly arranged toward the inside of the form 3 in the plurality of these shaft fastening members 12, and an inducing plate material 14 installed in the plurality of mutual these projecting shaft parts 13 and generating the crack in peripheral concrete. The concrete structure 1 is constructed by using such a crack inducing joint member 10. Thus, the joint part, the plurality of shaft fastening members, the plurality of projecting shaft parts and the inducing plate material can be integrated.;COPYRIGHT: (C)2009,JPO&INPIT
