Fireproof section piping penetration hole fireproof filling integrated sleeve assembly structure

摘要

The present invention relates to a fire-resistant filling integrated sleeve assembly structure for a fire protection section pipe penetration hole, and more particularly, an improved fire protection section that minimizes human damage by blocking the spread of smoke as well as flames due to high heat-resistant expansion in the event of a fire. It relates to a fire-resistant filling integrated sleeve assembly structure of a pipe through hole.
