CAST-IN-PLACE TWO-LAYERED REINFORCED CONCRETE PANEL Russian patent published in 2004 - IPC

FIELD: building, particularly for construction and reconstruction of bridge, berth and parking traffic areas, aerodrome and road pavement built on soft grounds and floor structures for civil building.

SUBSTANCE: panel comprises upper and lower slabs and resilient partitioning layer. Upper slab includes three parts, namely peripheral strips located along lower slab perimeter and having widths of perpendicular strips of e₁ and l₁, inner strips forming net inside lower slab perimeter and having widths of perpendicular strips of b₂ and l₂ accordingly and main parts located inside net defined by peripheral and inner strips and having dimensions of b₃ and l₃. Main parts contact with lower slab through resilient partitioning layer. Peripheral and inner strips are fixedly connected to lower slab by vertical anchors. Main parts are connected with inner and peripheral strips by horizontal anchors. e₁, l₁, b₂,l₂,b₃ and l₃, are determined from given relations.

EFFECT: increased rigidity and bending strength due to provision of combined action of panel layers.
