Description of the Related Art In a steel mortar finishing staircase, when mortar is placed on a step plate, conventionally, the step plate and riser plate are entirely welded to the side surface of the girder, while The mortar was placed by placing the reinforcing bars for mortar attachment in the space created between the risers.

れたものである。According to the conventional structure, before the mortar is cast, since the riser plate stands up front, the walkability is poor, and it is necessary to cure it with the temporary step plate. Also, since the step plate is entirely welded to the side gill girder and riser plate, it was not convenient because rainwater accumulated in the space where the mortar was placed. The present invention has been devised to solve such a problem.

体化する。[Means for Solving the Problems] A step plate is attached to a girder by bending both side portions, and an L-shaped groove is formed in the bent portion, and a hat-shaped groove is formed on the bottom of the upper surface of the step plate. Spot weld the reinforcement. A stud is welded to the gill girder, fitted into the L-shaped groove of the step plate, and the step plate is fixed to the gill girder with a nut. After that, the step plates are spot-welded to the riser plates hanging from the upper floor in order. A wire mesh is stretched on the hat-shaped reinforcing material of the step plate, and mortar is placed thereon to be integrated with the step plate.

An L-shaped groove 5 for fitting a stud 4 welded to the gilt girder 3 is formed on a side surface of the step plate which abuts on the gill girder 3.

Next, the front riser plate 6 is suspended from the step plate 1. The steel stairs are successively formed in this manner, and the wire mesh 7 is stretched on the hat-shaped reinforcing member 2 of the step plate 1 to cast mortar and the step plate 1 is integrated. FIG. 3 shows the condition and temporary condition of the step plate 1 integrated with the mortar.

However, according to the present invention, since the hat-shaped reinforcing material and the wire mesh are provided, the walkability before the mortar is placed is improved. Further, in the conventional structure, since the gill girder, the tread plate and the riser plate portion were completely welded, rainwater was not collected and the condition was bad. In the present invention, since the entire surface is not welded, there is no fear of rainwater collecting.
