SLEEVE FOR FORMING COMPARTMENT PENETRATING HOLE ON FLOOR OR WALL BODY OF BUILDING
PROBLEM TO BE SOLVED: To provide a sleeve having a strength against an external impact and adhesion of an expansion residue to concrete.SOLUTION: A sleeve 1 for forming a compartment penetrating hole on a floor or wall of a building has a second cylindrical body 20 having a thermal expandable body portion 21 fitted to a first cylindrical body 10. The first cylindrical body 10 and the second cylindrical body 20 are fixed to each other by a mutually overlapping overlapping portion 46, and an area S of contacting a peripheral surface of the first cylindrical body 10 and a peripheral surface of the second cylindrical body 20 in the overlapping portion 46 is 0
【課題】外部衝撃への強度とコンクリートに対する膨張残渣の密着性とを備えたスリーブを提供する。【解決手段】建築物の床又は壁に区画貫通孔を形成するためのスリーブ１は、第１筒体１０と互いに嵌合される、熱膨張性の本体部２１を有する第２筒体２０とを備えている。第１筒体１０と第２筒体２０とは互いに重なり合うオーバーラップ部４６で互いに固定され、オーバーラップ部４６において第１筒体１０の周面と第２筒体２０の周面が接触している面積Ｓが、０＜Ｓ＜（第２筒体の外周面全体の面積）である。【選択図】図４
