2. Description of the Related Art Recently, three-story buildings have attracted attention and have been built in many places because a large living area can be obtained in a narrow place of residential land. In this three-story building, the stairs on the first floor and the stairs on the second floor are almost at the same position in plan view to make it easy to plan and ascend and descend.
Often provided.

On the other hand, in a unit building, a box-shaped building unit having a fixed size that can be transported and having finished inside and outside is manufactured in a factory in advance, and a plurality of the building units are installed on a construction site. The building is transported to a building and assembled at a construction site to form a building, and is widely used because it has a feature of being a standardized building with short on-site construction time and high dimensional accuracy. The building unit used for this unit building is a building unit of a ramen structure in which steel frames and wood are assembled in a ramen structure, and a building of a framed wall construction method in which a wall panel or a floor panel in which a wall material or a floor material is attached to a frame is assembled. Two types of units are often used.

[0004] A typical building unit in which a steel frame is assembled in a ramen structure is, as described in Japanese Patent Publication No. 62-62224, four steel columns arranged at four corners of a square and four steel columns. The four steel floor beams connecting the lower ends of the pillars along the sides and the four steel ceiling beams connecting the upper ends of the four columns along the sides were assembled into a ramen structure. It has a skeleton, a steel floor beam is inserted between the opposite floor beams of the skeleton, a wooden floor joist is mounted on the floor beam, and a floor material is mounted on the floor joist to form a floor Then, a wooden ceiling edge is inserted over the opposite ceiling beam, a ceiling material is attached to the lower surface of the ceiling edge to form a ceiling, and a stud is provided between the ceiling beam and the floor beam at a place where a wall is provided. Attach the outer wall to the outside of this stud and the inner wall to the indoor side, and cut between the inner and outer walls. It is obtained by forming a wall mounting the wood.

[0005] A typical example of the building unit of the frame wall method is Japanese Patent Publication No. 58-30978 and Japanese Patent Application Laid-Open No. 61-20 / 1986.
As described in Japanese Patent No. 4443, a wall panel and a floor panel having a wooden frame are manufactured, and the floor panel and the wall panel are assembled in a box shape. In addition, the lower floor ceiling panel is attached to the upper floor building unit below the floor panel,
In many cases, only the upper-floor building unit is installed on the lower-floor building unit to form the lower-floor ceiling.

[0006] Also in this unit building, a three-story unit building is gradually increasing. In this unit building, in order to reduce the number of on-site construction steps, a factory manufactures a building unit with stairs with stairs attached inside the building unit beforehand, transports it to the construction site, and installs it on the construction site. In many cases, stairs are provided only by finishing.

As such a building unit with stairs, as described in JP-A-5-98707 and JP-A-7-76876, a building unit with stairs having substantially linear stairs, As described in JP-A-13310, the first stairs rising toward the wall, the periphery of the landing provided near the wall following the first stairs, and following the periphery, in the opposite direction to the first stairs. A stair composed of a second stair going up and a partition wall provided between the first stair and the second stair (hereinafter referred to as a U-shaped stair).
Building unit with stairs equipped with
As described in Japanese Patent Publication No. 0, there is a staircase-equipped building unit having a stair (hereinafter, referred to as a turning stair) in which a rotating portion rises while rotating instead of the landing of the U-shaped stairs. In particular, U-shaped stairs and turning stairs are often used in unit buildings because the stairs can be stored compactly in one building unit.

However, this three-story unit building is provided with a U-shaped staircase and a curved staircase in order to facilitate the floor plan and to ascend and descend similarly to the ordinary building. A difficult problem arises when the building unit with stairs on the first floor and the building unit with stairs on the second floor are installed as a building with the stairs at substantially the same position in plan view. That is, the stairs of the ceiling on the first floor and the floor on the second floor are cut out so that people who go up and down the second floor can pass through the stairs on the first floor. The ceiling on the second floor and the stairs on the floor on the third floor are cut off so that people who go up and down to the third floor can pass through the stairs on the second floor. That is, there is no floor or ceiling in the stairs of the building unit with stairs on the second floor between the first and third floors.

Therefore, when the building unit with the stairs on the second floor is used alone, it can be attached to the floor or the ceiling at the entrance side of the partition wall between the first staircase and the second staircase, but can be mounted on the wall side of the partition wall. There is a stairway between the and the partition wall, which is a passage for ascending and descending, and there is no upper and lower floors and ceilings, so the wall side of this partition wall can not be attached anywhere, and this part hangs Become. Even if the wall side of the partition wall is suspended and the interior side of the partition wall is mounted on the floor or ceiling at the entrance or exit, it is difficult to support the partition wall because the partition wall is heavy.

In particular, since no ceiling is provided in the framed wall construction method described in the above-mentioned publication, it is almost impossible to support this partition wall only by the floor portion of the rising opening. With such a structure, there is a problem that the building unit with the stairs on the second floor cannot be transported or stored alone. After the building unit with stairs on the second floor is set on the building unit with stairs on the first floor, the partition wall of the building unit with stairs on the second floor is placed on the partition wall of the building unit with stairs on the first floor. There is no problem because they are connected, and the above problem is a problem only in the case of a building unit with a staircase.

Therefore, an object of the present invention is to provide a U-shaped staircase or a turning staircase which can be stored and transported independently even if a partition wall is provided between the first staircase and the second staircase. Is to provide a building unit with.
