まず、支持盤１２を敷地６に配置し、本体部１０を立てる。ついで、アダプター２０を本体部１０の軸部１１に最上部から嵌め込む。そして、一対のバー保持部２２を持ってアダプター２０を回しながらアダプター２０を軸部１１に装着する。これにより、アダプター２０は、回りながら軸部１１を下降する。作業者は、のぞき窓２４からスケール１３の目盛り１４を確認しながら、アダプター２０を設定された高さ位置に調整する。これにより、アダプター２０が、図６に示されるように、本体部１０に装着される。
First, the support board 12 is arranged on the site 6, and the main body 10 is erected. Next, the adapter 20 is fitted into the shaft 11 of the main body 10 from the top. Then, the adapter 20 is mounted on the shaft portion 11 while rotating the adapter 20 while holding the pair of bar holding portions 22. Thereby, the adapter 20 descends the shaft 11 while rotating. The operator adjusts the adapter 20 to the set height position while checking the scale 14 of the scale 13 from the viewing window 24. Thereby, the adapter 20 is mounted on the main body 10 as shown in FIG.
ついで、図７に示されるように、ジャッキベース１のバー４ｂをバー保持部２２に挿入する。これにより、バー４ｂがバー保持部２２に挿入され、２つのジャッキベース１が、図８に示されるように、本体部１０に装着されたアダプター２０に保持される。このとき、図示されていないが、ジャッキベース１はアダプター２０に片持ち支持されており、傾斜してアダプター２０に保持される。
Next, as shown in FIG. 7, the bar 4b of the jack base 1 is inserted into the bar holding portion 22. As a result, the bar 4b is inserted into the bar holding portion 22, and the two jack bases 1 are held by the adapter 20 mounted on the main body 10, as shown in FIG. At this time, although not shown, the jack base 1 is supported by the adapter 20 in a cantilever manner, and is held by the adapter 20 at an angle.
ついで、図９に示されるように、ジャッキベース１の傾斜する姿勢を直して、第１腕部３１内にバー４ｂを挿入しつつ、第２腕部３２内に突起部２３を挿入する。これにより、図１０に示されるように、ジャッキベース１が、アダプター２０と連結具３０とに支持されて、支柱２が軸部１１と平行となった姿勢で宙に浮いた状態で、ジャッキベース高さ調整治具に保持される。
Then, as shown in FIG. 9, the inclination of the jack base 1 is corrected, and the bar 4 b is inserted into the first arm 31 while the projection 23 is inserted into the second arm 32. As a result, as shown in FIG. 10, the jack base 1 is supported by the adapter 20 and the connector 30, and the jack 2 is suspended in the air in a posture in which the support 2 is parallel to the shaft 11. It is held by the height adjustment jig.

敷 Then, as shown in FIG. 11, while turning the column 2, the floor 3 is lowered until the floor 3 touches the site 6. Next, the connecting tool 30 is removed, and the bar 4b is pulled out from the bar holding portion 22, so that the jack base 1 in which the height position of the bar 4b is the set height position is obtained.
この操作を繰り返し、１回に２台ずつの高さ調整されたジャッキベース１が得られる。
繰 り 返 し By repeating this operation, two jack bases 1 whose height is adjusted at a time are obtained.
実施の形態１によれば、ジャッキベース高さ位置調整治具は、軸部１１に装着されたアダプター２０のバー保持部２２の支持盤１２からの高さ位置が調整可能となっている。そこで、予め、軸部１１に装着されたアダプター２０のバー保持部２２の支持盤１２からの高さ位置が設定された高さ位置に調整されたジャッキベース高さ調整治具を用いて、ジャッキベース１を設定された高さ位置に調整できる。これにより、コンベックを用いて、受け部材４を回しながらジャッキベース１の高さを１つ１つ調整するような煩雑な調整作業が不要となり、足場の設置作業性が高められるとともに、作業時間を短縮することができる。
According to the first embodiment, the jack base height adjusting jig can adjust the height position of the bar holding portion 22 of the adapter 20 mounted on the shaft portion 11 from the support plate 12. Therefore, using a jack base height adjustment jig in which the height position of the bar holding portion 22 of the adapter 20 mounted on the shaft portion 11 from the support plate 12 is adjusted to a set height position in advance, The base 1 can be adjusted to the set height position. This eliminates the need for a complicated adjustment operation such as adjusting the height of the jack base 1 one by one while rotating the receiving member 4 using the convex, thereby improving the workability of setting the scaffold and shortening the work time. Can be shortened.
軸部１１に形成されたスケール１３の目盛り１４を読み取りながら、アダプター２０のバー保持部２２の支持盤１２からの高さ位置を調整できる。これにより、コンベックを用いる必要がなく、軸部１１に装着されたアダプター２０のバー保持部２２の支持盤１２からの高さ位置の調整作業が簡易となる。
While reading the scale 14 of the scale 13 formed on the shaft portion 11, the height position of the bar holding portion 22 of the adapter 20 from the support plate 12 can be adjusted. Thus, there is no need to use a convex, and the work of adjusting the height position of the bar holding portion 22 of the adapter 20 mounted on the shaft portion 11 from the support plate 12 is simplified.
なお、上記実施の形態１では、軸部１１にスケール１３を形成しているが、スケール１３を省略してもよい。この場合、最初の１度だけ、コンベックを用いて、アダプター２０の高さ位置を調整する。そして、高さ調整されたジャッキベース高さ調整治具を用いて、１回に２台ずつの高さ調整されたジャッキベース１が得られる。
In the first embodiment, the scale 13 is formed on the shaft portion 11, but the scale 13 may be omitted. In this case, the height position of the adapter 20 is adjusted only once by using the convex. Then, using the jack base height adjustment jig whose height has been adjusted, two jack bases 1 whose height has been adjusted at a time are obtained.
