Ceramic component for wing unit or space grid in building construction field, has terminal area fixedly connected to hollow ceramic body, and component surface comprising technical surface with average roughness in specific range

摘要

The element has a hollow ceramic body (2) comprising two terminal areas (3), and a non-positive shock joint connection formed from two ceramic hollow bodies with an internal bulk head. The respective terminal area is fixedly connected to the hollow ceramic body, and comprises a sintered component surface with screw hole. The terminal area is embedded to an adjacent respective mounting recess (8) in the ceramic body. A component surface comprises a polished technical surface with average roughness in a range from 0.8-1.6 micrometer.
