[Background Art] In recent years, the unit construction method, which has been widely used for building buildings such as houses, uses modular building units such as living room units and roof units in which various parts constituting the building are assembled in a factory. After production, these building units are transported to the construction site, and at the construction site, these building units are combined to construct a unit building. Such a unit construction method has the advantages of simplifying the work at the construction site and shortening the construction period.

Conventionally, among such building units, there is a building unit with stairs in which a stairway for connecting the building unit on the lower floor and the building unit on the upper floor is previously provided inside the building unit. When manufacturing this building unit with stairs in a factory, a ceiling beam and a floor beam are erected between the upper and lower ends of the pillars erected at the four corners to form a box-shaped frame. Install the staircase elements inside,
Stairs were formed in the building unit.

That is, the conventional building unit with stairs is
The stairs were formed in the building unit by sequentially assembling the stairs, partition walls, and other stair elements constituting the stairs in the assembled frame.

[0005]

However, assembling the stair elements individually in the frame of the building unit as in the conventional method causes a complicated manufacturing work of the building unit and
There is a problem of lengthening the unit manufacturing line.

[0006] In addition, since the walls, which are the components of the stairs, are sequentially incorporated into the building unit during the work, the interior of the building unit becomes narrower as the work progresses, and the workability inside the building unit deteriorates. There is. Particularly, when the inner and outer wall panels are attached to the frame, there is a drawback that the working position is limited because the work cannot be performed from the outside.

The present invention has been made in view of such circumstances, and when manufacturing a building unit with stairs in which stairs are incorporated in a building unit in a factory, it is possible to eliminate complication of work and An object of the present invention is to provide a method for manufacturing a building unit with stairs, which can shorten the unit manufacturing line and does not deteriorate workability during manufacturing.

[0008]

SUMMARY OF THE INVENTION The present invention combines a first step of assembling a beam to a plurality of columns to assemble a rectangular parallelepiped frame, and a plurality of step elements in a place separate from the first step. The second step of assembling the stairway device by means of the third step, and the third step of assembling and installing the stairway device in the frame.
It is characterized by including a process.

[0009]

According to the present invention, the skeleton and the staircase device are manufactured by the first and second steps, which are separate manufacturing lines, and the skeleton manufactured by the first step is manufactured by the second step in the third step. The built-in staircase device is installed. That is, after the frame and the stairway device are separately completed in the first step and the second step, the staircase is incorporated into the frame. Therefore, the first manufacturing process of the frame
There is no need to assemble stair components into building units during the process.
