Abstract

Structural element for heat-insulating purposes between two structural parts, in particular between a building (A) and a projecting exterior part (B), formed of an insulating body (16), which is to be arranged between the two structural parts, and of reinforcing elements in the form of at least load-bearing elements (19a, 19b) which, with the structural element (10) in the installed state, run through the insulating body substantially horizontally and transversely to the substantially horizontal longitudinal extent of the insulating body, and can be connected at least indirectly to each of the two structural parts, wherein the load-bearing element is formed in more than one part and has at least one load-bearing web (19a, 19b) and a separate compressive-force-distributing element (20a, 20b) on at least one of its end sides (22a, 22b, 22c, 22d) directed towards the one of the two structural parts, and the compressive-force-distributing element (20a, 20b) is produced from a material which has a level of thermal conductivity λ which is lower than 2.0 W/mK.
