<p><P>PROBLEM TO BE SOLVED: To provide a through-hole blocking tool which blocks a through-hole with a heat-resistant filler simply and in a short period of time. <P>SOLUTION: The through-hole blocking tool T comprises: an annular retaining frame 1 having a mounting portion for the outside surface of a structure W in which the through-hole A for inserting a long object is formed, and outwardly provided in a through-hole projecting portion projecting from the through-hole A in the long object P; the heat-resistant blocking member 3 disposed between the inner peripheral surface of the annular retaining frame 1 and the outer peripheral surface of the long object P to block an opening A1 of the through-hole A; and retaining frame splits 4 in which the annular retaining frame 1 is circumstantially divided into a plurality of sections. In the annular retaining frame forming process, the heat-resist blocking member 3 is formed by filling a soft heat-resist filler in a bag-like body, and the annular retaining frame 1 is formed by integrating a plurality of retaining frame splits 4 at least in the outside of the structure W so as to be retained in the inner peripheral surface side of the retaining frame splits 4. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
