WALL PENETRATION HOLE FORMING MEMBER
To provide a wall penetration hole forming member which can surely prevent that smoke at the occurrence of a fire at one side of a zone moves to the other side via a penetration hole.SOLUTION: A wall penetration hole forming member comprises a frame member 3 which is insertable into piping, and a pair of block members 4, 4 inserted into one end part of the frame member 3 in a piping insertion direction, and filling a gap between the frame member 3 and the piping 2. The frame member 3 comprises diameter-contracted parts S which become small in diameters as progressing toward depth sides of the block members 4 in an insertion direction at both end parts in the piping insertion direction, and the block members 4 comprise deformation parts 43 which are contracted in diameters by the diameter-contracted parts S by the insertion of the block members 4 into the frame member 3.SELECTED DRAWING: Figure 9
【課題】区画の一方側で火災が発生した時の煙が貫通孔を介して他方側へ移動することを確実に阻止することができる壁への貫通孔形成部材を提供する。【解決手段】配管を挿通可能な枠部材３と、枠部材３の配管挿通方向一端部に挿入して枠部材３と配管２との間の隙間を埋める一対の阻止部材４，４と、を備え、前記枠部材３は、配管挿通方向両端部に阻止部材４の挿入方向奥側ほど小径となる縮径部Ｓを備え、阻止部材４は、阻止部材４の枠部材３への挿入により縮径部Ｓで縮径されるよう構成された変形部４３を備えている。【選択図】図９
