Abstract
A fireproof structure includes: a first heat-absorbing material that includes an inorganic porous formed body that has absorbed water, or a second heat-absorbing material that includes particles that include magnesium phosphate hydrate and a binder; and a fibrous heat-insulating material that includes inorganic fibers having a shrinkage ratio of 5% or less when allowed to stand at 1,100° C. for 24 hours.
Claims15
A fireproof structure comprising:
- (i) a first heat-absorbing material that comprises an inorganic porous formed body that has absorbed water and is packed in a packing material that breaks at 70 to 130° C., the inorganic porous formed body being a formed body that comprises an inorganic powder composed of a calcium silicate, or (ii) a second heat-absorbing material that comprises particles that comprise magnesium phosphate hydrate and a binder;
- and
- a fibrous heat-insulating material that comprises inorganic fibers having a shrinkage ratio of 5% or less when allowed to stand at 1,100° C. for 24 hours.
