SLEEVE AND COMPARTMENT PENETRATION STRUCTURE
PROBLEM TO BE SOLVED: To provide a sleeve which is excellent in fire resistance and which facilitates construction of a compartment penetration structure.SOLUTION: A sleeve placed before placement of concrete 3 to form a compartment penetration hole 16 in the concrete 3 includes a hollow sleeve body 12 that is made of a thermally-expansible fireproof resin material, and a fin part 18 that extends from an inner surface 12a of the sleeve body 12.SELECTED DRAWING: Figure 2
【課題】耐火性に優れ、かつ区画貫通構造の施工を容易にするスリーブを提供する。【解決手段】コンクリート３における区画貫通孔１６の形成用にコンクリート３の打設前に配置されるスリーブは、熱膨張性の耐火樹脂材料からなる中空のスリーブ本体１２と、スリーブ本体１２の内面１２ａから延びるヒレ部１８とを有する。【選択図】図２
