Inner surfaces (9, 10) of the bars, square steel and T-steel stuck at edges of heat insulating filling. Each of the bars, square steel and T-steel lie at a side edge of the heat insulating filling. Thickness of projecting arms (13) of a T-steel is the half of the thickness of the fire resistant separation wall.
