FIELD: building industry. SUBSTANCE: floor has header joists fixed by their ends into building walls and lower panel flanges supported by header joists. Panel cross section in plane perpendicular to header joist axes is in the form of several stacked rectangles. Lower rectangle height is equal to height of lower header joist flange, difference between rectangle lengths is equal to two widths of lower header joist flange. Panels are formed of gypsum concrete mixture with wood reinforcement arranged into gypsum concrete. Wood reinforcement is oriented parallel to long side of upper rectangle and has T-shaped cross area. Length of upper reinforcement part is equal to upper rectangle length. EFFECT: simplified structure, reduced cost. 2 dwg |
