図１１に示すように、桁材１５に取り付けてある各ステップ受け１５ａにステップ２１を取り付ける。次に、各支柱２３を所定間隔でステップ２１に取り付け、各支柱２３、２３間にパネル板２５を取り付ける。そして、各支柱２３に架設するように手すり受け２７を取り付け、その手すり受け２７に手すり２９を取り付ける。 (4) Steps for Attaching Steps, Supports, etc. As shown in FIG. 11, step 21 is attached to each step receiver 15a attached to the girder member 15. Next, the columns 23 are attached to the steps 21 at predetermined intervals, and the panel plate 25 is attached between the columns 23 and 23. Then, the handrail receiver 27 is attached so as to be erected on each support column 23, and the handrail 29 is attached to the handrail receiver 27.

実施の形態にかかる階段の製造方法の作用効果について説明する。
上金具３の取り付け位置を基準にして、桁材１５の寸法に合わせた伸縮棒９を用いて下金具１３の位置決めをして下金具１３を床７に固定するため、壁や床７が傾いている場合であっても、下金具１３の位置決めが容易であり、桁材１５の施工性が良いと共に施工誤差が少ない。
さらに、上金具３の取り付け位置を基準にしているため、上金具３の高さは変わらないことから、階段の蹴上げ寸法が変わらない。 The operation and effect of the method for manufacturing the stairs according to the embodiment will be described.
Since the lower metal fitting 13 is positioned and the lower metal fitting 13 is fixed to the floor 7 by using the telescopic rod 9 that matches the dimensions of the girder material 15 with reference to the mounting position of the upper metal fitting 3, the wall and the floor 7 are tilted. Even in this case, the lower metal fitting 13 can be easily positioned, the girder material 15 has good workability, and the work error is small.
Further, since the mounting position of the upper metal fitting 3 is used as a reference, the height of the upper metal fitting 3 does not change, so that the rise dimension of the stairs does not change.

図２に示すように、施工前の桁材１５に上金具３及び下金具１３が専用ボルト５１で取り付けてあるため、桁材１５を施工する際に、上金具３、下金具１３及び専用ボルト５１を別途準備する手間を省くことができる。また、準備忘れを防止できる。
さらに、上金具３及び下金具１３は桁材１５の中空に取り付けてあるため、桁材１５を施工現場に搬入する際に嵩張らない。
図３に示すように、伸縮棒９は、全長がスライドにより調整可能な構成であるため、様々な寸法の桁材１５の施工の際に使用することができる。 As shown in FIG. 2, since the upper metal fitting 3 and the lower metal fitting 13 are attached to the girder material 15 before construction with the dedicated bolt 51, when the girder material 15 is constructed, the upper metal fitting 3, the lower metal fitting 13 and the dedicated bolt are attached. It is possible to save the trouble of separately preparing 51. In addition, it is possible to prevent forgetting to prepare.
Further, since the upper metal fitting 3 and the lower metal fitting 13 are attached to the hollow of the girder material 15, the girder material 15 is not bulky when it is carried into the construction site.
As shown in FIG. 3, since the telescopic rod 9 has a configuration in which the total length can be adjusted by a slide, it can be used when constructing a girder member 15 having various dimensions.

本発明は、上述した実施の形態に限らず、本発明の要旨を逸脱しない範囲で種々変形可能である。
例えば、上金具３及び下金具１３は必ずしも桁材１５に取り付けていなくても良く、桁材１５とは別に梱包しても良い。
桁材１５からの上金具３及び下金具１３の取り外しは、伸縮棒９の長さを桁材１５の長さに合わせる前に行えば良く、伸縮棒９への伸縮棒取り付け治具１１の取り付けよりも後に行っても良い。
桁材１５を上金具３、下金具１３、伸縮棒取り付け治具１１に取り付ける際、専用ボルト５１を螺合により取り付けることに限らず、挿通により取り付けても良い。この場合、専用ボルト５１に代えてピン等の挿通部材を用いても良い。
伸縮棒９は伸縮棒取り付け治具１１を別途取り付ける構成ではなく、伸縮棒取り付け治具１１と一体の構成であっても良い。
また、桁材１５のステップ受け１５ａから遠い上側ボルト孔１５ｂ及び下側ボルト孔１５ｃに伸縮棒取り付け治具１１のボルト孔１１ａを合わせることで、伸縮棒９の長さを桁材１５の寸法に合わせても良い。その場合、壁面５に取り付けられた上金具３の下側のボルト孔３ｂと伸縮棒９の上端９ａ側の伸縮棒取り付け治具１１のボルト孔１１ａとに専用ボルト５１を挿通して伸縮棒９を上金具３に取り付ける。また、下金具１３を床７に取り付ける際に壁面５に近い側となるボルト孔１３ｂと伸縮棒取り付け治具１１のボルト孔１１ａとに専用ボルト５１を挿通して伸縮棒９を下金具１３に取り付ける。
伸縮棒９の下端９ｂへの下金具１３の取り付けは、伸縮棒９の長さを桁材１５の長さに合わせた後、且つ下金具１３を床７に固定する前に行えば良く、必ずしも上金具３に伸縮棒９の上端９ａを取り付けた後に行わなくとも良い。
伸縮棒９を上金具３及び下金具１３に取り付ける場合、上金具３に伸縮棒９の下端９ｂを取り付け、下金具１３に伸縮棒９の上端９ａを取り付けても良い。
伸縮棒９は、第１棒部材９ｃと、第２棒部材９ｄと、第３棒部材９ｅとの３つの棒部材で構成することに限らず、２つ又は４つの棒部材で長さを伸縮自在に構成しても良い。
間隔確認治具１９を用いて壁面５に取り付けた上金具３、３の間隔の確認する際に、上金具３の立上部３ｆの右側を切欠部１９ａの右端に合わせて、上金具３、３の間隔を確認しても良い。 The present invention is not limited to the above-described embodiment, and can be variously modified without departing from the gist of the present invention.
For example, the upper metal fitting 3 and the lower metal fitting 13 do not necessarily have to be attached to the girder material 15, and may be packaged separately from the girder material 15.
The upper metal fitting 3 and the lower metal fitting 13 may be removed from the girder material 15 before the length of the telescopic rod 9 is adjusted to the length of the girder material 15, and the telescopic rod attachment jig 11 may be attached to the telescopic rod 9. You may go later than.
When attaching the girder material 15 to the upper metal fitting 3, the lower metal fitting 13, and the telescopic rod attaching jig 11, the special bolt 51 is not limited to being attached by screwing, but may be attached by insertion. In this case, an insertion member such as a pin may be used instead of the dedicated bolt 51.
The telescopic rod 9 does not have a configuration in which the telescopic rod mounting jig 11 is separately attached, but may have a configuration integrated with the telescopic rod mounting jig 11.
Further, by aligning the bolt hole 11a of the telescopic rod mounting jig 11 with the upper bolt hole 15b and the lower bolt hole 15c far from the step receiver 15a of the girder material 15, the length of the telescopic rod 9 is adjusted to the dimension of the girder material 15. You may match it. In that case, the telescopic rod 9 is inserted through the bolt hole 3b on the lower side of the upper metal fitting 3 attached to the wall surface 5 and the bolt hole 11a of the telescopic rod mounting jig 11 on the upper end 9a side of the telescopic rod 9. Is attached to the upper metal fitting 3. Further, when the lower metal fitting 13 is attached to the floor 7, a special bolt 51 is inserted into the bolt hole 13b on the side close to the wall surface 5 and the bolt hole 11a of the telescopic rod mounting jig 11, and the telescopic rod 9 is attached to the lower metal fitting 13. Install.
The lower metal fitting 13 may be attached to the lower end 9b of the telescopic rod 9 after adjusting the length of the telescopic rod 9 to the length of the girder material 15 and before fixing the lower metal fitting 13 to the floor 7. It is not necessary to do this after attaching the upper end 9a of the telescopic rod 9 to the upper metal fitting 3.
When the telescopic rod 9 is attached to the upper metal fitting 3 and the lower metal fitting 13, the lower end 9b of the telescopic rod 9 may be attached to the upper metal fitting 3, and the upper end 9a of the telescopic rod 9 may be attached to the lower metal fitting 13.
The telescopic rod 9 is not limited to being composed of three rod members of the first rod member 9c, the second rod member 9d, and the third rod member 9e, and the length can be expanded and contracted by two or four rod members. It may be freely configured.
When checking the distance between the upper metal fittings 3 and 3 attached to the wall surface 5 using the space confirmation jig 19, align the right side of the rising portion 3f of the upper metal fitting 3 with the right end of the notch 19a, and align the upper metal fittings 3 and 3 with the right end. You may check the interval between.
