SLEEVE, COMPARTMENT PENETRATION STRUCTURE, AND REFRACTORY FILLING STRUCTURE
PROBLEM TO BE SOLVED: To provide a sleeve, at a low cost, which is capable of reliably closing a compartment through hole when a fire occurs while preventing leakage of sounds, water or smoke through the compartment through hole without giving a user any psychological anxiety.SOLUTION: Disclosed sleeve 1 is used for forming a compartment through hole 11 in a floor or wall of an architectural structure. The sleeve 1 includes: a first cylindrical body 2; a second cylindrical body 3 having heat expandability; a third cylindrical body 4; and a non-expandable material 5. The sleeve 1 has a hollow part 10 which is constituted of an inner part 7 of the first cylindrical body 2, an inner part 8 of the second cylindrical body 3 and an inner part 9 of the third cylindrical body 4 which are continuously connected to each other, in which one end part of the second cylindrical body 3 is inserted into an expanded diameter part 15 of the first cylindrical body 2, and the other end part of the second cylindrical body 3 inserted into an expanded diameter part 15 of the third cylindrical body 4. The hollow part 10 functions as the compartment through hole 11, and the non-expandable material 5 is disposed on the hollow part 10.SELECTED DRAWING: Figure 2
【課題】材料コストを安価に抑えつつ、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、火災の非発生時でも、ユーザの心理面に不安を与えることがなく、区画貫通孔を通じた音漏れや水漏れや煙漏れが生じることを防止可能な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、非膨張性材５とを備える。スリーブ１では、第２筒体３の一端側部が第１筒体２の拡径部１５内に挿入され、第２筒体３の他端側部が第３筒体４の拡径部１５内に挿入されることで、第１筒体２の内部７と第２筒体３の内部８と第３筒体４の内部９とが連なった中空部１０が構成される。中空部１０は、上記の区画貫通孔１１として機能するものであり、非膨張性材５は、中空部１０に配置される。【選択図】図２
