<p>PROBLEM TO BE SOLVED: To reduce labor in an inserting operation of a long member by smoothly carrying out insertion. SOLUTION: This fire-resisting seal holding member is attachable to a through-hole 1 formed on a wall 2 or a flour of a construction member such that the long member P can be inserted into the hole. The fire-resisting holding member has at its center a long member insertion space 6 into which the long member P can be inserted, and comprises: a main body 4 inwardly insertable into the through-hole; and a flange 5 of a ring shape capable of abutting to a periphery of an opening of the through-hole 1. The fire-resisting seal holding member is provided at its main body 4 with thermal expansible a fire-resisting seal member 3 to be arranged at a space between the long member P and an inner peripheral surface 1a of the through-hole 1 in a state of the long member P inserted into the main body 4 and the flange 5. Of both ends of the main body 4, the end opposite to the flange 5 is formed with a recess groove 9 capable of holding a part of the fire-resisting seal member 3.</p> |
