In the present embodiment, the thickness or height H of the concrete 3 is substantially equal to the distance from the upper end to the lower end of the sleeve assembly 1. In this way, the concrete 3 is placed around the outside of the sleeve assembly 1 while leaving the opening 6 inside the sleeve assembly 1.

  The opening 6 inside the sleeve assembly 1 functions as a partition through hole 46.

  Next, one or a plurality of penetrating members, for example, pipes 46 are applied through the partition through holes 46 so as to penetrate the concrete 3. When a fire occurs from the direction of the arrow downstairs in the partition penetrating structure 100, the second sleeve 20 of the sleeve assembly 1 expands due to the heat of the fire, filling the gap between the sleeve 10 and the pipe or wiring 5, and Block the course. Further, the closing member 15 of the first sleeve 10 and the closing member 35 of the third sleeve 30 are in contact with the pipe 46 to close the space around the pipe 46 and block the course of fire. In this way, the sleeve assembly 1 not only facilitates the placement of the concrete 3 but also exhibits fire resistance and imparts fire resistance to the partition penetration structure 100. The sleeve assembly 1 need not be pulled out after the concrete 3 is cured.

  In this manner, the partition penetration structure 100 can be constructed by using the sleeve assembly 1 of the present invention with fewer steps than in the past.
