  • a staircase space is provided to connect each floor thereby enabling freedom of movement to upper and lower floors.
  • a building wall such as a partition wall, and a staircase installed independent of the building wall constitute this staircase space.
  • the term "staircase” includes a closed stringer staircase, an open stringer staircase, and the like, and these stringers included in these staircases are installed where the front surface of the overlay of the building wall is.
  • independent of the building wall means that another member of the staircase or the like is a member separate from the building wall, and encompasses both a form in which the other member is in contact with a surface of the building wall and a form in which the other member is separated from the surface of the building wall.
  • Patent Document 1 proposes a handrail-equipped indoor staircase that includes a closed stringer on a side of a wall panel.
  • This handrail-equipped indoor staircase has a handrail supported by arms projecting from a wall surface of one of the wall panels surrounding the right and left sides of the staircase, and the closed stringer attached to the wall panels facing the handrail is divided into two upper and lower stringer members with a tread and a riser as a boundary therebetween, and the tread and the riser are inserted into insertion grooves between the upper stringer member and the lower stringer member.
  • a staircase connecting multiple floors (the first floor and the second floor, for example) is constructed, studs included in the building wall are installed on the side of the staircase, an underlay is constructed by installing underlay face members between the studs and the staircase and fastening the underlay to the studs, and an overlay is constructed by installing overlay face members between the underlay and the staircase and fastening the overlay to the underlay.
  • an objective is to provide a building wall constructed in the vicinity of one such building member constructed in advance, thereby facilitating the fastening of an underlay face member and an overlay face member included in the building wall.
  • a building wall according to another aspect of the present disclosure includes:
  • FIG. 1 is a front view illustrating a state in which underlay face members are fastened to studs in a building wall according to an embodiment for forming a staircase space.
