construction engineering, particularly, supporting units of three-core panels of walls, partitions, etc. SUBSTANCE: supporting unit includes ends of flat sidings connected by layer of light warmth-keeping member and edging member in the form of channel. Edging channel internal cavity has transverse diaphragms cantilevered to its wall and are short of its flanges. Provided in flanges between diaphragms are projections. Diaphragms on wall of edging channel and flange projections are made by stamping. EFFECT: increased bearing capacity of three-core panels under action of clamping longitudinal forces. 2 cl, 4 dwg |
