MANUFACTURING METHOD OF PRECAST SEGMENT
To provide a manufacturing method of a match cast method capable of manufacturing a precast segment easily and with high linear accuracy.SOLUTION: A manufacturing method includes: a step of producing a semi-finished product member 101 of a precast segment 1; a step of providing at least three protrusions 18 on one end surface 112a, and 113a in the bridge axis direction of an upper floor slab body 112 and a lower floor slab body 113; a step of arranging an adjacent precast segment 2 at a position where it abuts on at least the three protrusions 18 for use as a match cast gable formwork of the semi-finished product member 101; and a step of placing concrete or mortar into a gap L formed between the semi-finished product member 101 and the adjacent precast segment 2 to integrate with the semi-finished product member 101.SELECTED DRAWING: Figure 6
【課題】プレキャストセグメントを簡単且つ高い線形精度をもって製造することができるマッチキャスト方式の製造方法を提供する。【解決手段】プレキャストセグメント１の半製品部材１０１を製作するステップと、上床版本体１１２及び下床版本体１１３の橋軸方向の一端面１１２ａ、１１３ａに少なくとも３つの突起１８を設けるステップと、半製品部材１０１のマッチキャスト妻型枠として用いるべく、隣接プレキャストセグメント２を、少なくとも３つの突起１８に当接する位置に配置するステップと、半製品部材１０１と隣接プレキャストセグメント２との間に形成された隙間Ｌにコンクリート又はモルタルを打設して半製品部材１０１に一体化させるステップとを含む構成とする。【選択図】図６
