COMPARTMENT PENETRATION STRUCTURE
PROBLEM TO BE SOLVED: To provide a compartment penetration structure capable of reliably preventing fire from propagating through a compartment penetration hole.SOLUTION: A compartment penetration structure 1 includes: a floor 2 or wall body comprising a heat insulation material D and concrete C as a member other than the heat insulation material D; a sleeve 3 installed on the floor 2 or wall body in order to form a compartment penetration hole T; and piping 13 or wiring arranged in the sleeve 3. The sleeve 3 includes a first cylinder 6, a second cylinder 7 having thermal expansion property, and a positioning cylinder 8. The compartment penetration hole T is configured such that the inside of the first cylinder, the inside of the second cylinder 7 and the inside of the positioning cylinder 8 communicate with each other. A range 7a of an outer peripheral surface of the second cylinder 7 is covered with the concrete C.SELECTED DRAWING: Figure 1
【課題】区画貫通孔を通じて火災が伝播することを確実に防止可能な区画貫通構造を提供する。【解決手段】本発明の区画貫通構造１は、断熱材Ｄ、及び当該断熱材Ｄ以外の部材としてのコンクリートＣから構成される床２又は壁体と、区画貫通孔Ｔを形成するために床２又は壁体に設置されるスリーブ３と、スリーブ３内に配置された配管１３又は配線とを備える。スリーブ３は、第１筒体６と、熱膨張性を有する第２筒体７と、位置調整筒体８とを備え、区画貫通孔Ｔは、第１の筒体の内部と、第２筒体７の内部と、位置調整筒体８の内部とが連なることで構成される。第２筒体７の外周面の範囲７ａは、コンクリートＣによって覆われる。【選択図】図１
