Zusammenfassung: | To provide a fireproof partition wall suppressing hot air leakage from horizontal joints, having excellent fireproof performance and workability.SOLUTION: A fireproof partition wall 100 of both surfaces with a single face, having multiple studs 10 and a pair of a first wall 30A and a second wall 30B sandwiching the multiple studs 10, with multiple face bars 20 formed by being arranged vertically and horizontally. The first wall 30A and the second wall 30B have vertical joints 60 and horizontal joints 70. The studs 10 are present on a rear face of the vertical joint 60, and a joint substrate 40 with a T-shaped side section, having a rear face piece 41 and an overhanging piece 42 extended in the thickness direction of a gypsum board 20 and having flame-resistant performance, is arranged to the horizontal joints 70. All of the face bars 20 are fastened to the studs 10 with first fastening members 50, and at least one of butt ends 21, 22 of the two vertically adjacent face bars 20 is fastened to the overhanging piece 42 with second fixing members 55.SELECTED DRAWING: Figure 6
【課題】横目地からの熱風漏れを抑制して耐火性能に優れ、施工性に優れた耐火間仕切壁を提供する。【解決手段】複数のスタッド10と、複数のスタッド10を挟む一対の壁であって、複数の面材20が上下左右に配設されて形成される第1壁30A及び第2壁30Bとを有する、両面1枚張りの耐火間仕切壁100であり、第1壁30Aと第2壁30Bには縦目地60と横目地70が形成され、縦目地60の背面にはスタッド10が存在し、横目地70には、横断面形状がT型であり、背面片41と、石膏ボード20の厚み方向に張り出す張り出し片42を有し、遮炎性能を有する目地下地材40が配設され、全ての面材20はスタッド10に対して第1固定部材50にて留め付けられ、上下方向に隣り合う2つの面材20の少なくとも一方の小口21,22が、張り出し片42に対して第2固定部材55にて留め付けられている。【選択図】図6 |
