As a result, the frame body W ₁₀₂ is attached to the upper column main body 33 of the waist wall column 101 and the front column 30, the lower side is supported by the 15th metal fitting 95 and the 5th metal fitting 85, and the upper side is the 16th metal fitting. It is supported by 96 and the sixth metal fitting 86.

Here, as shown in FIG. 24, the upper support main body 33 to which the frame body W ₁₀₂ of the waist wall panel ₁₀₂ is attached is fixed to the beam member 1a forming the upper floor 3 via the fixing bracket 106. Has been done.

Next, the action in the partition structure of the stairs of Example 1 will be described separately by "openness giving action", "stair width reduction suppressing action", and "other characteristic actions".

[Opening effect]
In the partition structure 20 of the stairs of the first embodiment, as shown in FIGS. 2A, 2B, etc., the stairs were erected from the floor surface 2a of the lower floor 2 and erected between the lower stairs 11 and the upper stairs 12. A plurality of columns (front column 30, center column 40, rear column 50) and a wall panel 60 provided between the plurality of columns (front column 30, center column 40, rear column 50) are provided. There is.

The upper end edge 63a of the wall surface panel 60 is inclined along the slope of the lower staircase portion 11, and the upper end edge 63a is set at a position lower than the side girder 12a of the upper staircase portion 12. The upper panel portion 63, the upper end edge 64a and the lower end edge 64b are inclined along the slope of the upper staircase portion 12, and the lower end edge 64b is set at a position higher than the upper end edge 63a of the lower panel portion 63. It has 64 and an open portion 65 provided between the upper end edge 63a of the lower panel portion 63 and the lower end edge 64b of the upper panel portion 64.

As a result, the lower panel portion 63 and the opening portion 65 are provided at the lateral positions of the lower staircase portion 11, and the space between the lower staircase portion 11 and the upper staircase portion 12 may be closed. It is possible to secure air permeability and daylighting through the opening portion 65. Therefore, even if the wall surface panel 60 is installed and partitioned between the lower staircase portion 11 and the upper staircase portion 12, the feeling of blockage and oppression can be reduced, and a feeling of openness can be felt.

[Stair width reduction suppression effect]
In the partition structure 20 of the stairs of the first embodiment, as described above, a plurality of columns (front columns) that are erected from the floor surface 2a of the lower floor 2 and are erected between the lower stairs 11 and the upper stairs 12. A wall panel 60 is provided between 30, the central column 40, and the rear column 50). Here, the lower panel portion 63 in which the upper end edge 63a is inclined along the slope of the lower staircase portion 11 and the upper panel portion 64 in which the upper end edge 64a and the lower end edge 64b are inclined along the slope of the upper staircase portion 12 Are provided on a plurality of columns (front column 30, central column 40, rear column 50).
Therefore, the structure for supporting the two panel portions (lower panel portion 63 and upper panel portion 64) can be made common, and the number of parts can be reduced.

Further, the two panel portions (lower panel portion 63 and upper panel portion 64) are not displaced in the width direction of the stairs 10 and are overlapped in the vertical direction. This makes it possible to prevent the effective stair width of the stairs 10 from being reduced.

Further, in the first embodiment, the lower handrail portion 71 and the upper handrail portion 72 are supported by a plurality of columns (front column 30, center column 40, rear column 50) provided with the wall surface panel 60. Has been done.
Here, the lower handrail portion 71 is in an inclined state that matches the gradient of the lower staircase portion 11. Further, the upper handrail portion 72 is in an inclined state corresponding to the gradient of the upper staircase portion 12.

That is, a plurality of columns (front column 30, central column 40, rear column 50) in which the lower handrail portion 71 and the upper handrail portion 72 are all erected between the lower staircase portion 11 and the upper staircase portion 12 ) Is supported. Therefore, the structure that supports the lower handrail portion 71 and the structure that supports the upper handrail portion 72 can be shared. For example, when the structure that supports the handrail 70 is folded back along the stairs. In comparison, it is possible to prevent the effective stair width from being reduced. Further, by sharing the structure for supporting the lower handrail portion 71 and the structure for supporting the upper handrail portion 72, the number of parts can be reduced.

[Strength improvement effect]
In the partition structure 20 of the stairs of the first embodiment, the front support column 30, the center support column 40, the rear side support column 50, and the waist wall support column 101 are all formed by a hollow rectangular tube to be the outer support column portion (lower). It has a side support main body 32, an upper support main body 33, a support main body 42, a support main body 52, and a waist wall support 101). Inner reinforcing members 34, 44, 54, 104 are attached to each of the support main bodies (lower support main body 32, upper support main body 33, support main body 42, support main body 52, waist wall support 101), respectively. It is contained.

Here, in order to secure the required strength only by each support main body (lower support main body 32, upper support main body 33, support main body 42, support main body 52, waist wall support 101), the cross-sectional area Will become too large, the design will deteriorate, and the effective stair width of the stairs 10 will be narrowed.

On the other hand, as described above, on the aluminum support main body (lower support main body 32, upper support main body 33, support main body 42, support main body 52, waist wall support 101) to be the outer support. By accommodating the iron inner reinforcing members 34,44,54,104, the support main body (lower support main body 32, upper support main body 33, support main body 42, support main body 52, waist wall support 101). ) Can be prevented from becoming large in cross-sectional area, and the strut strength (strut rigidity) can be improved.

Moreover, in the first embodiment, iron outer reinforcing members 35, 45, 55 are provided on the side surfaces of the support column main body (lower support main body 32, upper support main body 33, support main body 42, support main body 52). It is provided. Therefore, the strength of the strut main body (lower strut main body 32, upper strut body 33, strut body 42, strut body 52) can be further improved.

In the first embodiment, the outer reinforcing members 35, 45, 55 and the first outer reinforcing member 35a arranged between the pair of first locking claws 32b, 32b that support the first decorative plate 36a and the like. It has a second outer reinforcing member 35b and the like arranged between a pair of second locking claws 32c and 32c that support the second decorative plate 36b and the like.
