JIG FOR ASSEMBLING/DISASSEMBLING GAS TURBINE CASING, GAS TURBINE PROVIDED WITH SAME, AND METHOD FOR ASSEMBLING AND METHOD FOR DISASSEMBLING GAS TURBINE CASING

摘要

This assembly/disassembly jig (40) has: an affixed section affixed to one half-casing among a lower-half casing (30a) and an upper-half casing (30b); and a jack-receiving section (47) that extends from the affixed section and faces the outer surface of the other half-casing. If the spacing between both ends of the upper-half casing in the peripheral direction expands due to heat deformation, the affixed section of the assembly/disassembly jig is affixed to the lower-half casing, a jack (60) is disposed between the jack-receiving section of the assembly/disassembly jig and the outer surface of the upper-half casing, and the spacing between both ends of the jack is expanded.
