The present invention relates to a turbomachine with a housing structure as well as a corresponding housing structure an outer housing wall and an inner housing wall, which, passing around the flow duct of the turbomachine at a distance from each other, surround the outer side of the flow duct, wherein the inner housing wall of the housing structure is formed by an OAS (outer air seal, outer fluid seal) in the region of the rotating blades of the turbomachine, which rotate around an axial axis of the turbomachine, wherein a heat protection shield is constructed between the outer housing wall and the OAS. The heat protection shield has a plurality of spacers in the peripheral direction that are distanced from one another in the peripheral direction and are situated additionally to and in the radial direction outside of the heat protection element.
