FIELD: manufacture of wall and ceiling panels with concealed electric wiring from such construction material as concrete. SUBSTANCE: after installation of plastic box with tubes on square head of metal fixing rod welded with lower base to bottom of horizontal form ( installation is carried out through square hole in bottom of box which dimensions correspond to dimensions of square head of fixing rod in its cross-section ) additional operation is performed - box with tubes is turned through 45 deg about vertical axis on neck of fixing rod. As result sides of square hole in bottom of box are brought under angles of square head of fixing rod and box is appeared to be reliably anchored on fixing rod. Boxes do not float up in process of moulding of panels in horizontal forms. EFFECT: improved quality of construction panels. 4 dwg
