FIELD: construction.
SUBSTANCE: invention relates to the field of construction, in particular to the lining of rough steps of stairs, located both in enclosed spaces and in places exposed to precipitation and negative temperatures, and also when using fixed formwork to form the front surface of the stairs. Technical result is achieved by the fact that the facing concrete element of the stair tread contains monolithically molded treads with a riser, on the tread there is a cornice, monolithically molded with tread, covering a gap between the tread of the upper facing element and the lower riser when facing the staircase.
EFFECT: technical result is to ensure the tightness of the cladding surface of the steps of the stairs, accelerate installation, hardening the outer edge of the step.
