The present invention provides a stationary blade of integrated segment construction, in which a thermal barrier coating can be applied to the whole blade surface and excessive stress can be avoided in a shroud. A plate seat connector is provided at each end face portion of an inside shroud and an outside shroud attached to outside and inside ends of gas turbine stationary blade. Several stationary blades are integrated by joining the plate seat connectors of the adjacent shrouds by means of bolts and nuts to provide a stationary blade of integrated segment construction.

[ That which is claimed:] [1.]1. A stationary blade segment for an integrated segment construction including a plurality of stationary blades for a gas turbine comprising:a blade having outer and inner ends, an outside shroud joined to the outer end, and an inside shroud joined to the inner end, each shroud having an end face portion adapted to abut an end face portion of an adjacent stationary blade segment shroud; anda plate seat connector affixed at each end face portion of the inside shroud and the outside shroud, each plate seat connector extending outwardly away from its corresponding shroud and comprising a flat seat face at an outer portion thereof, each of said plate seat connectors being adapted to receive a bolt for securing the seat face thereof in face to face contact with the seat face of an adjacent plate seat connector, the seat face of each said plate seat connector being non-contiguous with respect to the end face of the end face portion of the shroud to which said connector is affixed.
