FIREPROOF MEASURE STRUCTURE, FIREPROOF MEASURE METHOD AND HEAT-EXPANSION FIREPROOF SHEET MATERIAL
PROBLEM TO BE SOLVED: To improve workability while securing fireproof performance, in a case of taking a fireproof measure at a portion where a plurality of long bodies are integrally inserted into an open hole of a fireproof structure.SOLUTION: A fireproof measure structure provided between an open hole 6H formed in a fireproof structure 6 and a plurality of long bodies 7 includes a heat-expansion fireproof sheet material 1 comprising a heat-expansion fireproof material layer and an adhesion layer provided along an entire area in a longitudinal direction. The heat-expansion fireproof sheet material 1 is wound around the plurality of long bodies 7, and is adhesion-held along an outer surface shape of the flux of the plurality of long bodies 7 by the adhesion layer.SELECTED DRAWING: Figure 1
【課題】耐火構造体の貫通孔に複数の長尺体がまとめて挿通される部位に防火措置を施す場合において、耐火性能を担保しながら施工性を向上させる。【解決手段】耐火構造体（６）に形成された貫通孔（６Ｈ）と複数の長尺体（７）との間に設けられる防火措置構造は、熱膨張性耐火材層と長手方向全域に沿って設けられる粘着層とを含む熱膨張性耐火シート材（１）を備える。熱膨張性耐火シート材（１）が、複数の長尺体（７）に対して共巻きされているとともに、粘着層により複数の長尺体（７）の束の外面形状に沿って粘着保持されている。【選択図】図１
