PURPOSE:To enable execution of a supporting frame installation independently from installation of structural members by integrally forming multi-layered cylindrical iron plates and radially disposed iron plates by pouring concrete thereto except plural aperture parts. CONSTITUTION:The supporting frame 1 consists of the iron plates integrated with the multi-layered cylindrical iron plates and the plural radially disposed iron plates and is constituted by pouring the concrete therein except the plural apertures 4. Carrying and installing of the structural member 6 are possible by a crane at the time of construction. Construction is possible independently of installation of pipings, cable boxes, etc., at the time of building the frame for supporting a reactor pressure vessel. Furthermore, the integral carrying and installing of the supporting frame 1 are possible, thus all the operations can be progressed regardless of the placement and curing period of the internal concrete.
