SLEEVE FOR FORMING SECTION THROUGH-HOLE ON FLOOR OR WALL BODY OF ARCHITECTURAL STRUCTURE
PROBLEM TO BE SOLVED: To provide a sleeve that has strength against an external impact and adhesion of expansion residue to concrete.SOLUTION: A sleeve 1 for forming a section through-hole on a floor or a wall of an architectural structure comprises: a hollow first sleeve 10, which has a body part 11 and an increased diameter part 16 continuing from the body part 11; and a hollow second sleeve 20, which has a thermal expansion body part 21 capable of engaging with inside of the increased diameter part 16 of the first sleeve 10. The sleeve 1 satisfies any one of following relationships (i) to (iii): (i) an inner diameter of the body part 11 of the first sleeve 10 is smaller than that of the body part 21 of the second sleeve 20; (ii) the inner diameter of the body part 11 of the first sleeve 10 is equal to that of the body part 21 of the second sleeve 20; and (iii) the inner diameter of the body part 11 of the first sleeve 10 is larger than that of the body part 21 of the second sleeve 20, and the difference between the inner diameter of the body part 21 of the second sleeve 20 and that of the body part 11 of the first sleeve 10 is 8% or less of the inner diameter of the body part 11 of the first sleeve 10.SELECTED DRAWING: Figure 4
【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、本体部１１と、本体部１１と連続する拡径部１６とを備えた中空の第１スリーブ１０と、第１スリーブ１０の拡径部１６内に嵌合可能な熱膨張性の本体部２１を有する中空の第２スリーブ２０とを備えている。スリーブ１は、下記の（ｉ）〜（ｉｉｉ）のいずれかの関係を満たす：（ｉ）第１スリーブ１０の本体部１１の内径は第２スリーブ２０の本体部２１の内径よりも小さい、（ｉｉ）第１スリーブ１０の本体部１１の内径が第２スリーブ２０の本体部２１の内径と等しい、または（ｉｉｉ）第１スリーブ１０の本体部１１の内径が第２スリーブ２０の本体部２１の内径よりも大きく、かつ第２スリーブ２０の本体部２１の内径と第１スリーブ１０の本体部１１の内径の差が第１スリーブ１０の本体部１１の内径の８％以下である。【選択図】図４
