本発明は壁あるいは床貫通部の防火工法に関づるもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fire protection construction method for wall or floor penetrations.
ビル、プラントなどの各種建築物にＪ３いては、隔壁が
設けられているにもかかわらず、電線、ケープ、水道管
、ガス管等が隔壁を貫通しているため、火災時において
は貫通空隙部を経て延焼し、大事に至ることが多い。Even though bulkheads are installed in buildings, plants, and other types of structures, electric wires, capes, water pipes, gas pipes, etc. pass through the bulkheads, so in the event of a fire, the penetration voids may be damaged. After that, the fire spreads and often leads to serious injury.
この貫通部を防火処理するため種々の提案がなされてお
り、例えばモルタル処理の他、パテ状耐火シール材が用
在広く用いられている。Various proposals have been made to provide fireproof treatment to this penetrating portion, and for example, in addition to mortar treatment, putty-like fireproof sealing materials are widely used.
しかし、間口部の大きな貫通部のにうな場合、パテ状シ
ール拐を多ｍに充填するのは非能率的であり、また新た
に配管するような場合、解体づるのは容易でない。However, in the case of a penetrating part with a large frontage, it is inefficient to fill the putty-like sealant in large quantities, and it is not easy to disassemble the pipe when installing new piping.
本発明は上記に基ぎ、充填作業Ｊ３よび解体作業が簡単
で、しかも耐火性に優れた実質的に１（【煙害の貫通部
防火工法の提供を目的と゛するものである。Based on the above, the present invention aims to provide a fire prevention construction method for smoke-damaged penetrations, which is easy to perform filling work and demolition work, and has excellent fire resistance.
すなわち、本発明はセラミックスバルクファイバ、紅白

ある。これらの無樫粉末は袋から飛散しないように粒子
径は比較的大ぎいものがよい。The inorganic powder is 4 pJ, an' as a refractory material. Examples include magnesium silicate, aluminum silicate, and hydrated alumina. The particle size of these oak powders is preferably relatively large so as not to scatter from the bag.
これらの成分を均一に分散させるための少量の有機物、
例えば液状シリコーンを接着剤とＬノで使用しても差支

For example, liquid silicone may be used in combination with the adhesive.
レラミックスバルクファイバ、紅白および無機粉末を主
体とする不燃性材料は無機物からなる袋に詰められいシ
ールバッグとされ壁あるいは床貫通部に充填されて防火
処理される。Nonflammable materials mainly consisting of Reramix bulk fiber, red and white powder, and inorganic powder are packed into bags made of inorganic materials to make sealed bags, which are then filled into wall or floor penetrations for fire prevention treatment.
袋とじＣはガラスクロスが適しており、これを用いるこ
とにＪ：す、耐火性に優れ、また有害なガスを発生ずる
ことがないシールバッグが得られる。Glass cloth is suitable for the bag closure C, and by using it, a sealed bag that has excellent fire resistance and does not emit harmful gases can be obtained.
シールバッグの大きさは任意に変えられるが、貫通部へ
の充填差作業に考慮すると４０ ｃｍ Ｘ ２０ ｃｍ
Ｘ ４ ｃｍ程度でｍざ１Ｋｇのものが適している。The size of the seal bag can be changed arbitrarily, but considering the difference in filling the penetration part, it is 40 cm x 20 cm.
Something that is about 4 cm x 1 kg and weighs 1 kg is suitable.
不燃性材料は袋単位であるため、貫通部への充填作業性
に優れ、しかも解体性は良好で、解体後も再使用できる
。Since the non-combustible material is made in bags, it is easy to fill the penetrating portions, and is easy to disassemble, allowing for reuse even after disassembly.
