TENDON ANCHORING STRUCTURE IN PRESTERESSED CONCRETE AND CONNECTION STRUCTURE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a tendon anchoring structure requiring no fixing anchor tool in prestressed concrete. ;SOLUTION: One end part 2a serving as a fixing end in a PC steel material 2 buried in concrete 1 is exposed from a cover 3 such as a sheath covering the PC steel material 2 and brought into contact with the concrete 1. Because of adhesion of the one end part 2a in the PC steel material 2 to the concrete 1 based on this contact, the one end part 2a serving as a fixed end in the PC steel material 2 is anchored to the concrete 1. In this way, in an anchoring structure for the PC steel material 2, only the exposure of the one end part 2a of the PC steel material 2 from the cover 3 is required, so that preparation of any special fixing anchor tool for anchoring is not required and the structure is simplified.;COPYRIGHT: (C)1999,JPO
