COMPARTMENT PENETRATION TREATMENT STRUCTURE, COMPARTMENT PENETRATION TREATMENT MATERIAL, AND CONSTRUCTION METHOD OF COMPARTMENT PENETRATION TREATMENT STRUCTURE
To provide a compartment penetration treatment structure, a construction method of the compartment penetration treatment structure, and a compartment penetration treatment material that can reduce variations in fire resistance performance and improve fire resistance performance.SOLUTION: Provided is a compartment penetration treatment structure in which a compartment penetration portion 15 formed in a partition portion 11 of a building and into which a long insertion body 21 is inserted has a fireproof structure. The compartment penetration treatment structure includes: a thermally expandable sheet member 3 which can be deformed from a sheet shape to a sleeve shape and at least a portion of which is inserted into an opening 13A of the compartment penetration portion 15 provided in the partition portion 11 in a state of being deformed into a sleeve shape with the ends overlapping each other, and which is arranged along the inner surface of the opening 13A; and an overlapping auxiliary portion 30 that is provided on the thermally expandable sheet member 3 and hides a gap caused by overlapping ends or guides the ends to overlap each other.SELECTED DRAWING: Figure 1
【課題】耐火性能のバラつきを低減し、かつ耐火性能を向上させることができる区画貫通処理構造、区画貫通処理構造の施工方法、及び区画貫通処理材を提供する。【解決手段】建築物の仕切り部１１に形成され、かつ内部に長尺の挿通体２１が挿通される区画貫通部１５を防火構造とする区画貫通処理構造であって、シート状からスリーブ状に変形可能であり、端部同士が重複するようにスリーブ状に変形した状態で仕切り部１１に設けられる区画貫通部１５の開口１３Ａに少なくとも一部が挿入され、開口１３Ａの内面に沿って配置された熱膨張性シート部材３と、熱膨張性シート部材３に設けられ、端部同士が重複することで生じる隙間を隠す、又は、端部同士が重複する配置となるように導く重複補助部３０とを備える、区画貫通処理構造。【選択図】図１
