Abstract

　熱変形および強度低下の恐れを抑制し、形状の自由度を確保し、圧縮機の圧縮性能を向上できる静翼環セグメントの組立方法等を提供することを目的とする。さらに、溶接時に溝や凹部から溶接対象物が浮き上がるのを防ぎ、溶接を良好に行うことのできる溶接を提供することを目的とする。 　各セグメント分割体４１に形成された溝５０の幅が外周側から底部５０ａに向けて漸次小さくなるよう、両側の側壁部５０ｂを底部５０ａに対して傾斜して形成し、結合部材４２を、その幅が、厚さ方向中間部の凸部４２ｂで最大になるような断面形状として、結合部材４２を溝５０に収容したときに、両側の凸部４２ｂが溝５０の側壁部５０ｂに当接あるいは近接し、溝５０の底部５０ａ側に空間１００が形成され、溝５０の底部５０ａから離れる側に断面略Ｖ字状の開先部２００が形成されるようにした。
