FIELD: construction engineering. SUBSTANCE: method and device involve placement of opening-formers easily moving through pan in mould; slots of top parts of opening-formers communicate with respective central duct formed along main axis of opening-former perpendicular to mould pan. Flexible tubular duct-formers for electric wiring are installed in slots so that central ducts are covered by at least at 0.01 of diameter or width of central duct; mentioned duct-formers are fastened relative to reinforcing net placed in mould on limiters of item protective layer width. After that laying of concrete mix, vibration compaction, thermal treatment, and form removal of item are made. EFFECT: facilitated manufacture; simplified design; reduced labor consumption and stock of metal moulds. 5 cl, 4 dwg
