FIELD: staircase frames.
SUBSTANCE: invention relates to staircase frames containing left and right stringers, and supporting elements of steps attached to them. The technical result is to increase the strength of the staircase frame while reducing material consumption. The technical result is achieved by the fact that the staircase frame contains left and right stringers and supporting elements of the steps attached to them, while the walls of the stringers are made of steel with a thickness of 2 mm and have bends along the entire length, forming stiffeners; the supporting elements of the steps are made of steel with a thickness of 2 mm and secured to the stringers by welding, the supporting elements of the steps are made in the form of a single part, which have a horizontal surface for fastening the step, a vertical surface perpendicular to it, while the horizontal and vertical surfaces have lateral bends for fastening to the stringers.
EFFECT: increase in the strength of the staircase frame while reducing material consumption.
