A spreader structure for a ring seal for sealing an annular gap, includes a radially inner first component with an inner contact surface, a radially outer second component with an outer contact surface, and a first spreading mechanism formed between these two components that includes a first spreading bevel formed on one of the two components, and a first spreading element formed on the other component, that can be moved along the first spreading bevel. The two components can be displaced in relation to one another, from an assembly state to a spreading state, by means of which the first spreading element is moved from a first section of the first spreading bevel to a second section of the spreading bevel, enlarging a radial spacing between the inner contact surface and the outer contact surface. The spreader structure has a second spreading mechanism.
