THROUGH-HOLE FIRE MEASURE TOOL

摘要

PROBLEM TO BE SOLVED: To provide a through-hole fire measure tool that can be easily installed in a through-hole under a state in which it is hardly released against the through-hole even in a case that an inner diameter is displaced from its designed size.SOLUTION: The present invention relates to a through-hole fire measure tool T for use in inserting a long body installed in a through-hole H belonging to a block body in which a cylindrical surface forming part of a base member 1 constituted to form a cylindrical surface 1a capable of covering an inner peripheral surface h1 of the through-hole H or constituted to enable the cylindrical surface 1a to be formed is provided with resilient salients 3 that are resiliently contacted with the inner peripheral surface h1 of the through-hole H under an adhered state against the through-hole H.
