A combustion chamber structure (1) comprising a plurality of cooling ducts (31, 41) extending in the longitudinal direction of the combustion chamber structure (1), whereby the combustion chamber structure (1) is rotationally symmetrical in relation to an axis (4) and comprised of an outer structure (11) and a base body (16) of the combustion chamber. The base body comprises ribs (25) preferably extending in the direction of the axis (4). The ribs are arranged in the peripheral direction of the combustion chamber structure and at least one first cooling duct (31) extends in the interior of the ribs.
