く。 First, the light emitting section 3 and the light receiving section 4 are set on the heads of the steel columns 1 and 2, respectively. At this time, the emission position of the reference beam L of the light emitting part 3 and the center position of the light receiving target 4d of the light emitting part 4 are at the same distance from the reference plane of both the steel columns 1 and 2 to be connected. Adjust the position of the main body 4c.

外れないように鉄骨柱２の吊込位置を調整・保持
しながら徐々に降し、鉄骨柱１上に建込む。 When the reference light beam L is received by the light receiving section 4, the received light signal is reflected on the construction accuracy reader 6 through the cable 5. The construction accuracy reader 6 is located in the operator's room of the construction machine, so the operator can read the reference light beam L reflected on the construction accuracy reader 6.
The steel column 2 is gradually lowered and erected onto the steel column 1 while adjusting and maintaining the hanging position so that the light receiving spot S does not come out of the field of view of the erection accuracy reader 6.
この場合、上記受光スポツトＳが建方精度読取
器６の視界から外れたら、警報ブザーが鳴るよう
にしてもよい。 In this case, an alarm buzzer may sound when the light receiving spot S goes out of the field of view of the construction accuracy reader 6.
尚、２つの鉄骨柱１，２の間に近接センサーを
取付けておけば、オペレーターがこの情況も正確
に把握しながら降下させることが出来る。 If a proximity sensor is installed between the two steel columns 1 and 2, the operator can accurately grasp this situation while descending.
鉄骨柱２が鉄骨柱１上に建込まれると、直ちに
接続作業に入る。 When the steel column 2 is erected on the steel column 1, connection work begins immediately.

共に、その状態を維持して鉄骨柱２を鉛直状態に
保ちながらボルトを本締めする。 In the connection work, first tighten the bolts temporarily, and then check the aiming position 6c of the construction accuracy reader 6.
The light receiving spot S of the reference light beam L is made to coincide with the reference beam L, and the bolts are fully tightened while maintaining this state and keeping the steel column 2 in a vertical state.
上記吊込情況は接続位置にいる作業員にも建方
精度読取器６′を通じて看取される。 The above-mentioned lifting situation can also be observed by the worker at the connection position through the construction accuracy reader 6'.
鉄骨柱２の接続が終了したら、発光部３および
受光部４を取外して、次の建方作業に移る。 When the connection of the steel column 2 is completed, the light emitting part 3 and the light receiving part 4 are removed and the next erection work is started.

過の邪魔にならない工夫を要する。 As shown in Figure 5, if the steel frame is a steel frame with a flange, such as an H-beam, instead of being attached to the steel column using the magnetic block described above, it may be clamped to the flange using screws, etc. You can also do this. In addition, as shown in Figure 6, when a steel frame column has a beam connection part or a part of the beam, etc.,
The light emitting section 3 and the light receiving section 4 need to be attached to corners or connecting parts of a steel column so that they do not interfere with the passage of the reference light beam L such as a laser beam.
