この発明は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籠の製作方法。[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a method for manufacturing a reinforcing bar cage used for reinforced concrete segments for tunnel lining.

The knitting and fabrication of reinforcing bar cages for reinforced concrete segments is more difficult than fabricating reinforcing bar cages for flat or cylindrical secondary concrete products. In other words, the circumferential direction of the segment has an arc shape with a large curvature, and the circumferential reinforcing bars are curved one by one at non-continuous points, and each reinforcing bar is organized with the tunnel reinforcing bars one by one, making it difficult to create other secondary concrete products. Automatic assembly using such a machine has not been carried out, requiring a great deal of manpower and making it difficult to improve the precision of machining dimensions.
この発明は前記従来の問題を解消し、編成の自
動化と省力化を目的とするものである。 This invention aims to solve the above-mentioned conventional problems and to automate and save labor in organization.

この発明の要旨とする構成は特許請求の範囲の
欄に記載の通り、特にその主要部とする点はトン

ので、その詳細を図面に基いて説明する。[Structure and Embodiments of the Invention] The gist of the invention is as described in the claims section, and its main part is that the reinforcing bars in the tunnel direction are made to stand upright on the circumference, and Circumferential reinforcing bars are arranged in a spiral around the outer periphery to lock both reinforcing bars, and then the circumferential reinforcing bars are cut at a predetermined dividing angle to create multiple reinforcing bar cages. The explanation will be based on the drawings.
図において１は周方向の鉄筋であり、２はトン
ネル方向、すなわち巾方向の鉄筋である。 In the figure, 1 is a reinforcing bar in the circumferential direction, and 2 is a reinforcing bar in the tunnel direction, that is, in the width direction.
まず鉄筋１はコイル状の状態で台Ａ上に回転し
うるように設置される。また鉄筋２はセグメント
の曲率に応した円周上、すなわちトンネル覆工の
中央部の円周上に所要間隔をもつて台Ｂ上に直立
させる。 First, the reinforcing bar 1 is placed in a coiled state on a table A so as to be rotatable. Further, the reinforcing bars 2 are stood upright on the table B at a required interval on the circumference corresponding to the curvature of the segment, that is, on the circumference of the center part of the tunnel lining.
次いで前記鉄筋１を引出し、ローラー等を通し
て各鉄筋２の下方より順次その外周にスパイラル
状に配置する。その際台Ｂも回転する。 Next, the reinforcing bars 1 are pulled out and placed in a spiral manner around the outer periphery of each reinforcing bar 2 sequentially from below through rollers or the like. At this time, table B also rotates.
鉄筋１，２の交点は電気溶接あるいは結束等に
よつて係止し、環状鉄筋籠を形成する。次いで各
所のセグメントの大きさ、すなわち周方向の長さ
に応じて予め分割角度α，β等を定めておき、こ
の分割角度をもつて周方向の鉄筋１をガスまたは
電気で切断して一重配筋の鉄筋籠を形成する。 The intersections of the reinforcing bars 1 and 2 are locked together by electric welding or binding to form a circular reinforcing bar cage. Next, dividing angles α, β, etc. are determined in advance according to the size of the segments at each location, that is, the length in the circumferential direction, and the reinforcing bars 1 in the circumferential direction are cut using gas or electricity at these dividing angles to form a single layer. Forms a rebar cage of reinforcement.
また通常の二重配筋の鉄筋籠の場合大小環状鉄
筋籠を形成し、内外鉄筋１，２を腹筋３で連結す

まめる場合と第５，６図のように鉄筋１，２に絡
ませる場合がある。そして鉄筋１，１の切断は腹
筋３の取付前でも取付後でもよい。 In addition, in the case of a normal reinforcing bar cage with double reinforcement, a large and small annular reinforcing bar cage is formed, and the inner and outer reinforcing bars 1 and 2 are connected by abdominal reinforcements 3. In that case, there are cases in which the reinforcing bars 2 and 2 are entangled as shown in FIG. 4, and cases in which the reinforcing bars 1 and 2 are entangled as shown in FIGS. 5 and 6. The reinforcing bars 1, 1 may be cut before or after the abdominal reinforcement 3 is attached.
なお切断時においても切断代は型枠内にセツト
したとき鉄筋かぶりをとることになる。 Furthermore, when cutting, the cutting allowance will cover the reinforcing steel when it is set in the formwork.
この発明は以上の構成からなり、周方向の鉄筋

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 circumferential length of each segment, allowing for quick assembly work. As well as being able to
Dimensional accuracy can be improved, multiple types of reinforcing bar cages can be manufactured at the same time, and work efficiency is high.
