<p>In the case of a ceramic structural element having a shell body bounding a hollow space, the ends open out into end faces. For producing a load-bearing element formed by two or more structural elements, arranged in the longitudinal direction one behind the other and with their hollow spaces in alignment, concrete or mortar is introduced into the hollow spaces. The structural element has an edge which protrudes in the longitudinal direction (11) of the structural element and extends on the outer side around the end face and the end face extends from the edge in the longitudinal direction (11) of the structural element in a set-back fashion as far as the inner side of the shell body bounding the hollow space. Before firing or hardening, the structural element is trimmed at, at least one end by means of a cutting wire (29) stretched between wire clamps (28). The cutting wire (29) is supported on at least one wire support (32), arranged between these wire clamps (28), and the wire support (32) is adjusted in dependence on the cutting operation during cutting by bending (38) of the cutting wire (29) at the wire support (32) transversely to the cutting movement of the cutting wire (29).</p> |
