Document Type and Number:
Japanese Patent JP2017177630
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To achieve the heat shield property and fire resistance equivalent to or more than those of the structure overlapping plural thick gypsum boards by a structure having a thickness thinner than the above.SOLUTION: A fireproof shield material 1 comprises a double layer structure of the surface and rear layers 1a, 1b having the same composition as each other, compacted by blending a thermal expansion agent comprising an expanded graphite or vermiculite into a wool mat in which the hot-melt heat resistant inorganic fibers comprising a rock wool or glass wool are piled to be entangled, and laminated in a thickness direction, and is expandable in the thickness direction by the thermal expansion agent at heating. A fireproof shield structure S is configured by setting the fireproof shield material 1 and a platy body comprising gypsum boards 5, 5 integrally laminated to at least one of the surface and the rear of the fireproof shield material 1.SELECTED DRAWING: Figure 1
