SLEEVE, SECTION PERFORATION STRUCTURE AND REFRACTORY FILLING STRUCTURE
PROBLEM TO BE SOLVED: To provide a sleeve capable of positively closing a section perforation structure at the time of occurrence of fire while restricting material cost to a less-expensive price, not giving any fear at a psychological aspect of a user even under no occurrence of fire and further capable of preventing sound leakage or water leakage or smoke leakage through the section open hole.SOLUTION: A sleeve 1 of this invention is used for forming a section open hole at either a floor or a wall of a building. The sleeve 1 comprises a first cylinder 10, a second cylinder 20, and a non-expansion material 30. The first cylinder 10 comprises a main body part 11, and a diameter expanded part 16 continuous to the main body part 11 through a step part 15. The second cylinder 20 includes a thermal expansion type main body 21 which is inserted into the diameter expanded part 16 of the first cylinder 10. The non-expansion material 30 is arranged at a hollow part 6 which is constituted by an inside part 10a of the first cylinder 10 and an inside part 20a of the second cylinder 20 which are continuous to each other.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、建築物の床または壁に区画貫通孔を形成するために使用される。スリーブ１は、第１筒体１０と、第２筒体２０と、非膨張性材３０とを備える。第１筒体１０は、本体部１１と、本体部１１に段差部１５を介して連続する拡径部１６とを有する。第２筒体２０は、第１筒体１０の拡径部１６内に挿入される熱膨張性の本体部２１を有する。非膨張性材３０は、第１筒体１０の内部１０ａと第２筒体２０の内部２０ａとが連なることで構成される中空部６に配置される。【選択図】図２
