この発明Ｌトンネル覆工用の鉄筋コンクリートセグメン
トに用いられる鉄筋篭の製作方法。[Detailed Description of the Invention] [Industrial Field of Application] This invention provides a method for manufacturing a reinforcing cage used for reinforced concrete segments for L tunnel lining.
鉄筋コンクリートセグメントの鉄筋篭の編成製作紘平板
状あるい１よ円筒状コンクリート二次製品の鉄筋篭の製
作より困難である。すなわちセグメントの周方向は大き
い曲率の弧状ｔなし。The formation and fabrication of reinforcing bar baskets for reinforced concrete segments is more difficult than the fabrication of reinforcing bar cages for flat or cylindrical concrete secondary products. That is, the circumferential direction of the segment does not have an arcuate shape t with a large curvature.

も加工寸法精度を上げることは困難であった。Where they are not continuous, the circumferential reinforcing bars are curved one by one, and each reinforcing bar is organized with tunnel reinforcing bars to form a 1L
Unlike other secondary concrete products, automatic assembly by machines was not performed, requiring a great deal of manpower, and furthermore, it was difficult to increase the accuracy of the processed dimensions.

筋篭とするもので、その詳細を図面に基いて脱明する。The configuration of the gist of this invention is as described in the column of the scope of the patent request.In particular, the main point is that the reinforcing bars in the tunnel direction are made to stand upright on the circumference, and the reinforcing bars in the circumferential direction are placed on the outer periphery of the reinforcing bars in the tunnel direction. The reinforcing bars are arranged in a spiral to lock both reinforcing bars, and then the reinforcing bars are cut in the circumferential direction at predetermined dividing angles to form a plurality of reinforcing bar baskets.The details will be explained based on the drawings.

い。This invention has the above-mentioned configuration, and can be arranged by continuously feeding out the reinforcing bars in the circumferential direction.The reinforcing bars for one ring can be arranged and then cut to the length of each segment in the local direction, resulting in quick assembly work. In addition to being able to increase the dimension by 8 degrees, multiple deaf reinforcing bars *' can be manufactured at the same time, which improves work efficiency.
