PROBLEM TO BE SOLVED: To shorten a construction process for the diaphragm floor of a reactor containment vessel. SOLUTION: Components for the diaphragm floor of a reactor containment vessel are assembled around a built-in beam 34 so as to include a diaphragm liner 85, they are changed into a module in the same arrangement as a set state, and the module 51 is carried into the reactor containment vessel by using a large lifting machine so as to be set on cradles 44, 45 which are installed on both a pedestal 11 at a reacor pressure vessel and a reactor-containment- vessel outer wall 13. In addition, when reinforced concrete is executed, a concrete placing operation is performed so as to be divided into a plurality of operations in the thickness direction, and a first concrete placing load is supported by the built-in beam 34 while the diaphragm liner 85 is connected to the built-in beam. After the first concrete has been solidified so as to generate its strength, a second concrete placing operation and subsequent placing operations are repeated, and placing loads in the operations are supported surely by the previously solidified concrete and by the built-in beam 34.
