Beschreibung
Zusammenfassung:	construction engineering. SUBSTANCE: plastic section has longitudinal walls of which at least one is inclined to section axis; these walls form chamber to receive metal reinforcing member with external and internal ledges provided with external and internal longitudinal walls joined to transversal ribs to form chambers. Internal ledge of section has at least one longitudinal rib arranged between its external and internal walls. Internal wall of internal ledge is bow-shaped structure or is shaped as dihedral angle of more than 90 deg. EFFECT: improved heat-insulating characteristics of blocks. 2 cl
