PURPOSE:To simplify the construction of step by a method in which the first side plate is set from the upstair to the downstair and the second side plate is coupled with the first side plate through the ends of step and step-in plates and a base wood. CONSTITUTION:The first side plate 21 is set between the base 80 of first floor and the receive beam of the landing or the floor beam 90 of second floor, and the other first side plate 21 is fixed to the column 100 and stand 110 of the central wall 16. A step plate 30 and a step-in plate 40 are fixed to the plates 21, and base woods 50 and 60 are each fixed to the ends of the plates 30 and 40 and the landing. The second side plate 22 is set between the first floor and the second floor to match it with the base woods 50 and 60 and fixed to the column 100 and the stand 110. Cloth is applied to the surfaces of plaster board and the second side plate 22 to hide the plate 22. |
