Claims

[Scope of utility model registration request]

A staircase system connecting an upper floor and a lower floor with a landing is formed by an upper stair unit extending from the upper floor and a lower stair unit extending upward from the lower floor, and the upper stair unit is A pair of parallel stringers made of a section steel material with a flange protruding laterally at one lower end and having a horizontal part forming a landing at the lower end of the downward slope; The upper splicing material that joins the stringers, the middle splicing material that joins the stringers at the inner and outer ends of the horizontal part, the lower splicing material, and the step plate arranged between the stringers at the sloped part are joined together in advance. The lower stair unit is made of a section steel material with a flange projecting laterally at the lower end of the upright, and has a pair of parallel stringers with a downward slope, and the stringers are connected at the upper end. The upper splice material and the step board placed between the stringers are joined together in advance, and one stringer of the lower stair unit or the upper splice material is connected to the stringer of the upper stair unit and its horizontal part. A mounting piece that is arranged in parallel and is bolted to one of the stringers of the upper stair unit, and a fixing piece that is bolted to one of the stringers of the lower stair unit or the upper joint material between them. A stair device that is connected by connecting fittings that are connected through joints.
