Abstract
A fastening device for a heat-protection shield of a gas turbine is provided with a center mounting element which has a defined installation clearance with a mounting slot in the radial direction. In the normal operating state, this mounting element has no function, such that thermal differential expansions in the radial direction between the heat-protection shield and its counterpart are possible without impairment within the limits of this defined clearance. The mounting element does not start to bear against the counterpart until the radial differential expansion exceeds the size s. The deformation of the heat-protection shield toward a component moving in a relative manner is thus limited and excessive grazing of the components against one another is avoided.
