Title: HEAT INSULATING STRUCTURE
Abstract:
The present invention is a heat insulating structure for covering, by means of a plurality of precast blocks, a metallic object to be covered, wherein the generation of gaps in an expansion allowance provided between adjacent precast blocks is suppressed during usage. The present invention thus provides a heat insulating structure in which a plurality of precast blocks A, B, in which a porous adiabatic aggregate having a mineral composition represented by CaO・6Al2O3 is blended, is installed so as to cover a metallic object to be covered 10, wherein fibers C containing 70 mass% or more of an Al2O3 component are disposed between adjacent precast blocks A, A and between adjacent precast blocks B, B.
