2. Description of the Related Art For example, as a kind of prefabricated house, a unit house using a box-shaped building unit is provided. In this building unit, most of the necessary equipment, outer wall materials, interior and exterior materials, etc. are assembled at the factory for each unit, transported to the construction site by trucks and other vehicles, and the required number is The houses are formed by being stacked side by side. This building unit is manufactured by required processes on a production line of a factory, and for each process, assembly of each member is completed by a predetermined number of steps on the production line.

[0003] By the way, in the unit housing, 2
Indoor stairs in multi-storey houses and the like are naturally installed on the production line. In this case, a sequential assembling method, in which the structural members of the stairs are sequentially assembled to the building unit, and a main unit is configured in advance as a stair unit, and the unit is assembled so that the stair unit is set to the building unit on the production line. There is a built-in method. Also, on the stairs,
There is also a decorative staircase in which the surface of the stair member is finished with a paint or a decorative material before assembling or assembling.

In the case where the stairs of the sequential assembling method or the stairs of the unit assembling method are provided on, for example, a wall surface in a building unit, a staircase wall and a tread plate and a riser plate are provided.
A gap of 2 to 3 mm is required for inserting a stair member or a stair unit along the wall of the staircase. And
After the assembling or the like, a stairway skirting board is attached to cover the gap and to prevent damaging the leg wall when going up and down the stairs. Since this staircase skirting is provided for the above purpose, it is generally installed after the stairs and the wall are fixed, and it is an installation work on a production line.

However, since the stair skirting board is separately provided on the left and right sides of the stairs, and is divided into each step of the stairs in order to be attached to a portion of the stairs having a complicated shape, the number of parts increases and the mounting time increases. Had been hanging for a long time. Further, since the decorated stairway skirting is a finishing material, it is necessary to attach the skirting board with care so that there is no gap between the stepboard and the riser board and the skirting board. Further, since the step board and the riser board are attached to a sasara girder having a structure whose dimensional accuracy is looser than these, a step board is required to attach a step board so that no gap is formed between members. In some cases, it is necessary to perform the mounting operation while partially cutting or correcting the part, so that extra time is required for mounting, and the working time may vary. In addition, because the staircase is small, it has not been possible to increase the number of installation workers.
For these reasons, the work time in the stair forming process area on the building unit production line may be long, and if the work is not completed within the set time, the work line must be temporarily stopped to complete the stair forming work. There is a problem such as not becoming.

As shown in FIG. 5, the step board 15 and the riser plate 18 of the stairs are assembled to the slab 20 and the stair skirting board 30 is temporarily fixed to both lateral ends of the step board 15 and the riser board 18 with staples S.

As the step board 15 and the riser board 18 of the stairs, those whose surfaces are finished by painting or decorative boards in advance or those made of base members whose surfaces are not decorative finished are appropriately used.
In addition, the sasara girder 20 is a member that is normally hidden between the staircase wall and the tread plate 15 and the riser plate 18 and is not exposed to the surface when the stair girder is completed as a stair. 15 and a stepped shape combined with the back surface of the riser 18. In addition, the material of the sasara girder 20 is appropriately selected.

The stair skirting board 30 is used to cover the gap between the stairs and the staircase wall when the stairs are completed, and to prevent damage to the staircase wall at the legs when the stairs are moved up and down, and is made of a decorative material. The staircase skirting board 30 of this example is composed of a number corresponding to the number of steps of the stairs, and is substantially inverted L in a side view cut out so as to be combined with the upper surface of the tread plate 15 at both ends in the horizontal direction and the front surface of the riser plate 18 in each step. The tread 15 and the riser 18 are temporarily fixed to the lateral sides 15a, 18a of the tread 15 with a required number of staples S.

The staple S is a well-known substantially U-shaped stopper, and one of its legs is connected to the step board 3.
0, and the other leg is driven into the side surface 15a, 18a of the tread plate 15 or the riser plate 18, thereby temporarily fixing the stair baseboard 30. Therefore, the stair skirting board 30 is prevented from moving in the direction orthogonal to the surfaces of the tread plate 15 and the riser plate 18 by the staples S, and has a width of 2 to 3 mm in the width direction A of the stairs (that is, the direction in which the staples S come out). The movement is made possible by pressing.

As a method of manufacturing the staircase unit 10 with a skirting board, first, the slab girder 20 is fixed on a predetermined jig in the same posture as when the stairs are installed in a building.

The staircase unit with skirting board 10 is formed in substantially the same state as the state in which the tread plate 15, the riser plate 18, the sash girder 20 and the stairway skirting board 30 are incorporated in the staircase room.

The staircase unit with skirting board 10 formed as described above is conveyed to a building unit production line of a factory or the like, and is arranged at a predetermined position in the staircase room of the building unit on the production line. Sasara girder 20 of stair unit 10
Is fixed to a structure such as a wall W or a floor of a staircase by a usual fixing method. At this time, the arrangement space of the stair unit 10 in the building unit is
In order to facilitate the work of arranging the stairs, the width of the stair unit is set to be larger than the width of the stair unit 10, so that a gap is generated between the stair skirting 30 and the wall W of the stair room after the arrangement.

The wall W of the staircase may be attached to the building unit in advance, or the staircase unit with skirting board 1
0 may be attached after being placed in the building unit. Alternatively, one staircase wall W may be attached to the building unit first, and the other staircase wall W may be attached after the stair unit 10 is arranged in the building unit.

Sasara girder 2 of staircase unit 10 with baseboard
After fixing “0” to a structure such as the wall W of the staircase, the staircase skirting 30 is pushed and displaced by hand or a jig so as to adhere to the wall surface Wa of the staircase and is fixed to the wall W. At this time, the stairs baseboard 3
0 indicates that the movement in the direction orthogonal to the plane of the tread plate 15 and the riser plate 18 moves laterally while being restricted by the staples S, so that no gap is formed between the tread plate 15 and the riser plate 18. In addition, the gap between the riser plate 18 and the staircase wall W can be easily, quickly, and reliably closed.

The stair skirting board 30 can be fixed to the wall material W easily and quickly by applying an adhesive to the back surface 31 of the stair skirting board or pasting a double-sided adhesive tape in advance. it can. Alternatively, the stair skirting 30 may be fixed with a nail or the like having a head of the same color as the decorative finish surface.
