SLEEVE AND COMPARTMENT PENETRATION STRUCTURE
To provide a sleeve for covering a compartment penetration open hole at a normal time while being capable of securely blocking the compartment penetration open hole at a fire occurrence time.SOLUTION: A sleeve 1 of the invention is used for forming a compartment penetration open hole 11 on a floor or wall of an architectural structure. The sleeve 1 comprises: a first cylindrical body 2; a second cylindrical body 3 having a heat expansion property; and a third cylindrical body 4. With the sleeve 1, one end part of the second cylindrical body 3 is inserted into an enlarged diameter part 15 of the first cylindrical body 2 while the other end part of the second cylindrical body 3 is inserted into an enlarged diameter part 15 of the third cylindrical body 4. A non-expansion part 6 is provided on the inner peripheral surface of at least one of the first cylindrical body 2 and the third cylindrical body 4.SELECTED DRAWING: Figure 2
【課題】火災の発生時に区画貫通孔を確実に閉塞できるとともに、通常時に区画貫通孔を被覆するスリーブを提供する。【解決手段】本発明のスリーブ１は、建築物の床又は壁に区画貫通孔１１を形成するために使用される。スリーブ１は、第１筒体２と、熱膨張性を有する第２筒体３と、第３筒体４とを備える。スリーブ１は、第２筒体３の一端部が第１筒体２の拡径部１５内に挿入され、第２筒体３の他端部が第３筒体４の拡径部１５内に挿入されることで構成される。第１筒体２及び第３筒体４のうちの少なくとも一方の内周面に非膨張部６が設けられている。【選択図】図２
