Estimating the term…
The present invention is provided for considerably shortening the construction time of a building that is applied to nuclear power plants. When constructing the building, megablocks having a height that extends to a plurality of floors are produced, and together with combining those megablocks, concrete is poured inside them to form a wall member composed of a megawall structure of steel plate reinforced concrete construction. Alternatively, in addition to the wall megablocks, floor megablocks for forming the floor member of the building are used, and together with combining those megablocks, concrete is poured inside or above them to form a structural member (wall member and floor member) composed of a megawall structure of steel plate reinforced concrete construction.
A building used for a nuclear power plant, wherein a wall portion which forms at least a part of said building is formed from a megawall structure of steel plate reinforced concrete construction that is composed by pouring concrete into megablocks composed of outer shell steel plates having a height equivalent to the plurality of floors of said building, and wherein an equipment module which is composed of steel frames formed by support columns that have a height equivalent to the plurality of said floors and function as columns inside said building and floor frames that are supported by said support columns and function as floors in said building, and various types of equipment to be installed in said building that are previously provided in said steel frames along with their ancillary piping, is provided in the building.
A building used for a nuclear power plant, wherein a wall portion which forms at least a part of said building is formed from a megawall structure of steel plate reinforced concrete construction that is composed by pouring concrete into megablocks composed of outer shell steel plates having a height equivalent to the plurality of floors of said building, and wherein said building is a reactor building comprising a containment vessel and a ring-shaped pool that employs a top slab of said containment vessel for its bottom, and said pool is integrally provided with said containment vessel by extending a peripheral wall of said containment vessel upward to form a pool outer peripheral wall that has a cylindrical shape when viewed from overhead and by providing a pool inner peripheral wall on said top slab so as to be concentric with said pool outer peripheral wall.
