Abstract (en)
The present invention provides a stationary blade of integrated segment construction, in which thermal barrier coating can be applied to the whole blade surface and an excessive stress is not produced in a shroud. A plate seat for bolt tightening is provided at each end face portion of an inside shroud and an outside shroud for a gas turbine stationary blade. Several stationary blades are integrated by joining the plate seats of the adjacent shrouds by means of bolts and nuts to provide a stationary blade of integrated segment construction. <IMAGE>
