Claim:
A guide vane element for a gas turbine, comprising: a first vane blade extending radially relative to the main body of the gas turbine between a first radially inward platform and a first radially outward platform; a second vane blade extending radially relative to the main body of the gas turbine between a second radially inward platform and a second radially outward platform; at least one edge of at least one of the first radially inward or outward platforms on a side of the platform facing away from the first vane blade adjoining an adjacent edge of an adjoining one of the second radially inward or outward platforms, a first flange being provided on said at least one edge and a second flange being provided on said adjacent edge, said flanges being for connecting adjoining platforms in a circumferential direction relative to the main axis of the turbine to form a cover band; the connection between said flanges including an area in flush contact on a side of said adjoining platforms facing away from the vane blades and an area having a gap between the adjoining platforms on a side facing the vane blades at a state when the platforms are exposed to high operating temperatures.
