FIELD: construction. SUBSTANCE: method includes making holes along hollows in supporting zone of hollow-core reinforced concrete slabs. Hole width equals hollow diameter. Introduced along hollows are metal sheets with fluted surface. Then, concrete mix is placed into hollows. Metal sheet may be rectangular in shape. To reinforce slabs, metal sheet is introduced into span. Metal sheet is narrowing towards span middle. Slab support zones are reinforced by introduction of metal sheet narrowing towards supports. EFFECT: higher efficiency. 4 cl, 7 dwg
