Abstract (en)
1. Heat-insulating hollow block, whereas those parts (4) of the web in a roughly perpendicular position to heat flow (1) in order to achieve backward slanting heat paths are angled backwards in respect to the wall plane and laterally reversed to planes of symmetry (3) in as much characterized, as web parts (5) connecting web parts (4) are featuring single or manifold breaks (6), as slabs (8) of highly insulating material are situated along the planes of symmetry (3), extending from web part (5) or (6) to adjacent web part (5) or (6) and snugly fitted against same, and as wedge-shaped air spaces (9) between said slabs and web parts (4) feature at their thinnest section (9.2) a thickness greater than zero which is achieved by distance ribs of roughly rectangular crossection (10) or triangular cross-section (11) sitting on the web parts (4).
Abstract (de)
Die Erfindung betrifft die Ausbildung des Steg-Gitters bei Hohlblocksteinen o.dgl., mit dem Ziel einer maximalen Verringerung des Wärmeflusses durch den Stein. Dies wird erreicht durch rücklaufend verschwenkte Längs- und zusätzlich geknickte Querstege, mit entlang der Symmetrieebenen der Längsstege eingebrachten Isolierplatten, sowie zwischen diesen uns den Längsstegen verbleibenden keilförmigen Luftschichten.
