INSTALLATION STRUCTURE OF EVACUATION HATCH
To enhance the appearance, improve safety, and enhance workability by minimizing the difference in level with respect to an outdoor floor area when installing an evacuation hatch.SOLUTION: In an installation structure of an evacuation hatch 10 which is fitted into and installed in an aperture 5 of an outdoor floor area 4, a first substrate plywood 6 is provided on the aperture 5 side of a wooden floor body 4a covered by a fire-resistant surface material G, a second substrate plywood 7 is provided on the top face side of the floor body 4a, a buffer material 8 is provided in a frame shape along the edge of the aperture 5, and the evacuation hatch 10 is fixed to the outdoor floor area 4 by placing a flange part 12 which extends outward from a cylindrical body frame 11 on the top face of the buffer material 8 and driving a fixing material 15 from an inner face of the cylindrical body frame 11 toward a core material F constituting the floor body 4a.SELECTED DRAWING: Figure 1
【課題】避難ハッチを屋外床部に対して極力小さな段差となるように設置することで見栄えを良くするとともに安全性の向上を図り、かつ、施工性を向上させる。【解決手段】屋外床部４の開口部５に嵌め込まれて設置される避難ハッチ１０の設置構造であって、耐火面材Ｇによって被覆された木造の床本体４ａの開口部５側に第一下地合板６が設けられ、床本体４ａの上面側に第二下地合板７が設けられており、緩衝材８が、開口部５の縁に沿って枠状に設けられており、避難ハッチ１０は、筒状本体枠１１から外側に張り出すフランジ部１２が緩衝材８の上面に載置されるとともに、筒状本体枠１１の内側面から床本体４ａを構成する芯材Ｆに向かって固定材１５が打ち込まれることで屋外床部４に固定されている。【選択図】図１
