<P>PROBLEM TO BE SOLVED: To provide a head backside structure enabling easy visual observation without requiring disassembly of the head backside for checking the soundness of an anchor end. <P>SOLUTION: A head backside structure includes a bearing plate (anchor plate 3) which supports tensile force acting on a tensile force support member (11), an anchor head support member (2) mounted on the bearing plate (3), and an anchor head (7) which fastens a vicinity of the upper end of the tensile force support member (tendon 11). The inner part of the anchor head support member (2) is filled with a corrosion inhibitor (e.g. grease), and a viewing window (2w) is provided on the anchor head support member (2). <P>COPYRIGHT: (C)2012,JPO&INPIT |
