Overlap holder for segmented liner of turbomachine component

A segmented liner for an exhaust diffuser of a turbomachine, the segmented liner comprising:

• a plurality of liner segments collectively defining an inner surface of the exhaust diffuser and including a first segment having an upper tongue at a first radial distance from a rotational axis of the turbomachine and a second segment having a lower tongue at a second radial distance that is larger than the first radial distance such that the upper tongue overlies the lower tongue;
• and
• an overlap holder coupling the first segment to the second segment, the overlap holder comprising:
• a main plate with a first face and a second face opposite the first face, wherein the main plate has a first end and a second end opposite the first end, and wherein the first face of the main plate engages the upper tongue;
• a spacer with a respective first face and a respective second face opposite the first face of the spacer, wherein the first face of the spacer engages the lower tongue, and the second face of the spacer engages the first face of the main plate;
• a top plate with a respective first face and a respective second face opposite the first face of the top plate, wherein the first face of the top plate engages the second face of the main plate;
• and,
• a fastener at each of the first end and the second end of the main plate, each fastener extending through respective holes in the spacer, the main plate, and the top plate, the respective fastener holding the spacer, the main plate, and the top plate in mutual engagement, wherein the spacer and the upper tongue define a gap therebetween in at least the circumferential direction.
