Furthermore, it is also possible to assemble the main body of the staircase in a factory or the like, thereby reducing on-site work time.

[0013] Furthermore, since the stair locking crosspiece is fixed in contact with the lower surface of the stair main body when the stair portion is completed, it also performs the function of reinforcing the installed state with respect to the stair main body. Furthermore, since the wall portion is formed of a plurality of wall panels, and the stair locking crosspiece is spanned over these plurality of wall panels, it also acts as a reinforcement for the wall portion.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the method of constructing a staircase section of the present invention will be described below with reference to the drawings.

First, FIG. 1 shows two walls 10 and 12 formed in the wall erection process. The stair body is installed between these two walls 10 and 12. Therefore, these two wall portions 10 and 12 are erected with an interval equal to the width of the stairs. Further, in this embodiment, the wall sections 10 and 12 each include three wall panels 10a to 1
2c, and 12a to 12c.

[0016] Next, in the crosspiece attachment step, stairway locking crosspieces are attached to the stairway installation sides of each of the walls 10 and 12 shown in FIG.

FIG. 2 shows one wall portion 12 to which the stair locking crosspiece 20 is attached. As shown,
The stair locking crosspiece 20 is formed into a single columnar body,
The staircase is attached to the wall part 12 with an appropriate slope angle. Moreover, this stair locking crosspiece 20 is attached over all three wall panels 12a to 12c that constitute the wall portion 12. Note that this installation involves fixing to each of the wall panels 12a to 12c with nails, screws, or the like.

Although not shown, the other wall portion 10
Similarly to FIG. 2, a stair locking crosspiece 20 is attached to the side surface of the stair installation.

Next, a stair main body temporary installation step is performed in which the stair main body is locked to the stair locking crosspiece 20 portion.

FIG. 3 shows the work in this process, in which the stair main body 18 is suspended with a rope 19, and the stair main body 18 is
The stair main body 18 is lowered so that the bottom part of the flat girder 14, which is a component of the stair case, comes into contact with the upper surface of the stair locking crosspiece 20. Then, as shown in FIG. 4, the bottom surface 14a of the crossbeam 14 is locked to the top surface of the stair locking crosspiece 20, and the temporary installation is completed.

[0021] Thereby, the stair main body 18 is installed with an appropriate stair inclination angle. In addition, in this temporarily installed state, the staircase main body can be slid on the upper surface of the staircase locking crosspiece 20, so the accurate positioning of the staircase main body 18 in the sliding direction can be extremely easily performed by the movement. be able to. That is, since the stair main body 18 is temporarily placed on the two stair locking bars 20, there is no need to perform lifting operations, etc., and this movement in the sliding direction can be performed even by a small number of workers. This makes the positioning work extremely easy.

[0022] Then, the staircase main body 1 is accurately positioned.

This is done by fixing, for example by nailing.

[0023] Through this series of steps, the construction work of the staircase portion is completed. After this, the work of attaching risers to the stair main body 18, attaching decorative boards, and furthermore installing support members from the lower side of the stair main body 18 are performed.

The state of the stair main body 18 after the fixing process is similar to that of the stair section shown in FIG. 5 above.

According to the above embodiment, by locking the relatively heavy stair main body 18 onto the stair locking crosspiece 20, it can be easily temporarily installed in an appropriate inclined state. Further, since more accurate position adjustment can be performed in this temporarily placed state, positioning work becomes extremely easy regardless of the weight.

[0026] Therefore, the working time can be shortened, and it is also possible to construct the staircase section in advance, not at the construction site, but during the unit manufacturing process at the factory where each unit is constructed by combining wall panels. becomes.

[0027]Thereby, by transporting and installing the unit in which the stairway has been constructed as is to the construction site, the stairway can be quickly installed at a predetermined position in the building. In this way, by constructing and installing the stairs from the beginning, when working on the second floor at the construction site, workers can use the stairs to go up and down the second floor, making the work more convenient. Improvements in sexual performance have also been achieved. In addition, when the stair main body 18 is fixed, as shown in FIG. 4, the stair main body 18 is supported by the stair locking crosspiece 20. It also has the effect of reinforcing this staircase part. Furthermore, since the stairway locking crosspiece 20 is spanned across a plurality of wall panels constituting the wall, it also serves the function of reinforcing the wall.
