解決するものである。SUMMARY OF THE INVENTION According to the present invention, there is provided a steel column and a steel bar surrounding a steel beam, and a column stage is provided on the steel column for each panel zone on each floor so as to be detachably mounted. The steps of installing handrails and lifting ladders on the column stage are performed on the ground, and only the installation of steel beams after the construction of the steel columns and the rebar construction of the panel zone are performed on the column stages built together with the steel columns. This solves the problems of the conventional construction method by working at a high place.

る(図4及び図5)。When the mounting of the receivers 5 by the bolt connection is completed, the column stage 6 is mounted on each receiver 5. The column stage 6 uses a duralumin product used for construction of a steel-framed building as it is, and is detachably attached to each receiving object 5 so that it can be removed later (FIGS. 4 and 5).

After that, a handrail 8 is attached to each column stage 6, and finally a ladder 9 for raising and lowering is attached to the upper and lower sides of the column stage 5 on one side, thereby completing the formation of the steel column 1 (see FIGS. 6 and 7). ).
【0014】上記柱の地組に並行して、図は省略した
が、鉄骨梁も地組場に並べて鉄筋組立を行う。この際、
主筋の長さは梁長より50cmほど短くしておく。In parallel with the column erection, though not shown, steel beams are also arranged on the erection site to perform rebar assembly. On this occasion,
The length of the main bar should be about 50 cm shorter than the beam length.

【発明の効果】この発明は上述のように、鉄骨柱と鉄骨
梁の周囲の鉄筋工事を足元の良い地上にて先に行うこと
から、品質の管理も行き届き、品質の確保が容易とな
る。As described above, according to the present invention, since the reinforce work around the steel column and the steel beam is performed first on the ground with good feet, the quality is well controlled and the quality can be easily secured.
【0019】また高所での鉄筋工事はパネルゾーンまわ

行える。In addition, the reinforcement work at high places is only around the panel zone, and it is not necessary to construct a large-scale scaffold for the reinforcement work as in the past, and the reinforcement in the panel zone can be preceded by the reinforcement. In addition, work setup can be advantageously performed.

ことができる。Further, the work of installing the steel beams in the panel zone and the rebar work are performed using the column stage mounted on the steel column on the ground as a scaffold, and the work is safely and efficiently performed because the elevating ladder and the handrail are already mounted. Can do well.
