Being fire-resistant protection structure for the cable and fire-resistant protection structure for the cable

摘要

PROBLEM TO BE SOLVED: To provide a fireproof protection technology for a cable which considers a fireproof protection performance against fire, a size (a thickness) and a durability, and is widely practical.;SOLUTION: A fireproof protection structure 14 is provided with an exterior material 1 for surrounding piping 9 for accommodating the cable 10 and attached to a constructed element 11, and a thermal insulation material 13 layered on an inner face of the exterior material 1. The layered thermal insulation material 13 is formed from a fiber reinforced cement plate or a gypsum board 4 as an inorganic thermal insulation material containing an inorganic hydrate in a third layer. An arrangement location of the fiber reinforced cement plate or the gypsum board receives a temperature within a range of 100-700°C.;COPYRIGHT: (C)2006,JPO&NCIPI
