The invention relates to a guide ring element (1a, 51a, 61a, 71a) for turbines and to a method for producing the same, wherein the guide ring element has a low weight and is easily produced, but nevertheless meets all requirements for strength. To this end, the flow surfaces of the guide ring element (1a, 51a, 61a, 71a) are constructed of segment plates (23, 24, 27, 28, 52, 53, 62, 63, 72, 73) that are small relative to the guide ring element (1a, 51a, 61a, 71a). In order to produce a guide ring element (1a, 51a, 61a, 71a), individual elements are connected to each other for forming the guide ring element (1a, 51a, 61a, 71a), wherein the different work steps of connecting the individual elements to each other and optionally to other individual elements take place either simultaneously or in an arbitrary sequence. |
