FIELD: construction.
SUBSTANCE: invention relates to construction. Method for manufacturing of prefabricated-monolithic reinforced concrete beam slabs of floors with round cavities, using non-extractable tubular cardboard-polyethylene cavities, includes production of reinforcement unified parts with non-extractable void-forming agents from cardboard tubes of round cross-section, covered with water-insulating polyethylene film with thickness of 0.045 mm and closed on ends with cardboard-polyethylene covers, and concreting of lower flange of plate in factory conditions or in specially designated place on construction site. Delivery and installation of assembly parts of floor slabs to design position. Connection rods are installed between prefabricated elements. If necessary, additional reinforcement is performed. Engineering pipes are installed and monolithic concrete of the rest part of the slab is laid.
EFFECT: technical result is reduced weight of precast-monolithic reinforced concrete slabs.
