Title: STEAM TURBINE ASSEMBLING METHOD, STEAM TURBINE, AND UPPER HALF ASSEMBLY
Abstract:
This steam turbine assembling method comprises: an upper half assembling step for disposing an upper half partition plate (31) having an upper half partition plate division surface (31X), on the inner peripheral side of an upper half casing (41) having an upper half casing division surface (41X), and then mounting, on the upper half casing (41) and the upper half partition plate (31), an upper half position regulating unit (5) ensuring that the upper half casing (41) and the upper half partition plate (31) are movable relative to each other such that the upper half partition plate division surface (31X) projects in a direction perpendicular to the upper half casing division surface (41X), thereby forming an upper half assembly; and a lower half assembling step for disposing, on the inner peripheral side of a lower half casing (42) having a lower half casing division surface (42X) that can be in contact with the upper half casing division surface (41X), a lower half partition plate (32) having a lower half partition plate division surface (32X) that can be in contact with the upper half partition plate division surface (31X), thereby forming a lower half assembly.
