Document Type and Number:
WIPO Patent Application WO/2018/025718
Kind Code:
A1
Abstract:
The present invention is a precast block structure obtained by integrating a metal plate and a precast block, wherein the occurrence of cracking in the precast block during the manufacture or use thereof is suppressed. Thus, in the present invention, a precast block structure A comprises a metal plate 1 capable of covering an outer circumference of a metallic object to be covered 11, and a precast block 2 which is integrated with the metal plate 1 and in which a porous adiabatic aggregate having a mineral composition represented by CaO・6Al2O3 is blended, the precast block structure having a ratio of the thickness of the precast block 2 to the length of the metal plate 1 (precast block thickness / metal plate length) of 0.2 to 0.4 in a cross section orthogonal to the longitudinal direction of the metallic object to be covered 11.
