[0077]
According to the invention of claim 2, the second staircase unit is dropped between the third wall portion after the middle wall portion is erected, and is disposed across the landing and the upper floor surface portion. However, since this middle wall portion covers the lower side region excluding the upper side region of the second stair unit, the risk of damaging the wall portion when the second stair unit is attached is reduced. The mounting operation of the second stair unit is also facilitated. Then, by raising the upper middle wall portion on the subsequent floor, one side portion of the second staircase unit is covered with the wall portion over the entire area, and a handrail or the like can be attached.
[0078]
According to the invention described in claim 3, the wall panel is transported to the site, and the wall portion to which the finishing material is attached is constructed only by being erected at a predetermined position. The construction work of the staircase area is further simplified.
[0079]
Further, the wall panel is formed by directly attaching an inorganic face material that forms a finishing material on both sides of a framed frame, and the stair unit is directly abutted and fixed to the wall surface of these wall parts. The width of the stepped portion of the staircase is made wider than in the conventional configuration in which the staircase unit is attached to the wall portion to which the finishing material is attached via the face material forming the wall surface as in the past. Since no attachment material or the like is required, the number of members can be reduced, and the installation operation is simplified.
[0080]
According to invention of Claim 4, the area | region under the landing part which can be utilized as an effective space can be ensured widely as an area | region with height. And this area | region can be utilized effectively, for example as a toilet and a container. In addition, since the number of steps of the second stair unit attached between the intermediate wall portion and the third wall portion that have already been erected can be reduced, it is possible to easily attach the second stair unit. can do.
[0081]
According to invention of Claim 5, the joint of an inorganic surface material can be eliminated, and the landing part side wall surface which a kick board material and a support wall make can be covered without a level | step difference. Therefore, the appearance of the side wall surface of the landing section formed by the kick plate material and the support wall is good, and cross cuts can be prevented when cross bonding is performed on the inorganic surface material as a finishing treatment.
