FIELD: construction. SUBSTANCE: inventions relate to the field of construction, in particular to monolithic or prefabricated monolithic ceilings of buildings. Method for forming the ends of a monolithic part of an overlap includes placing and fixing the end portions of the monolithic part of the slab of the transverse reinforcement in the form of U-shaped clamps to the reinforcement, to the vertical part of which the binding rods are fixed, which are preliminarily passed through the looped outlets of the structural element. Structural element for forming the ends of the monolithic part of the flooring contains a prefabricated reinforced concrete panel and loop outlets located on the inside of the panel. Inside of the panel is rough, and the outer one is smooth. EFFECT: technical result of the invention consists in increasing the technological reliability of the installation of the floor.
