To provide a sash frame and an assembly structure thereof which can be assembled without notch processing that requires skilled workers or expensive processing equipment, can be assembled only by cutting the dimensions of the shapes even when the dimensions of the shapes need to be shortened due to changes in the dimensions of an opening at the construction site of a building, and enables the assembly direction of the shapes required for correct assembly of the sash frame to be easily confirmed.SOLUTION: Of a first corner block 61 connecting a left vertical frame 2 to an upper horizontal frame 4, a second corner block 62 connecting the upper horizontal frame 4 to a right vertical frame 3, a third corner block 63 connecting the right vertical frame 3 to a lower horizontal frame 5, and a fourth corner block 64 connecting the lower horizontal frame 5 to the left vertical frame 2, at least two of the corner blocks shall be configured to have the same shape as each other, or to have a mirror image shape of each other.SELECTED DRAWING: Figure 1 【課題】加工者の熟練または高価な加工装置が必要な切欠加工を行うことなく、かつ、建物の施工現場において開口部の寸法変更等により形材の寸法を短くする必要が生じた場合でもその寸法を切断加工するのみで組付可能であり、かつ、サッシ枠の正しい組み立てに必要な形材の組付方向を簡単に確認できるサッシ枠及びその組付構造を提供する。【解決手段】左縦枠２と上横枠４とを接続する第１のコーナーブロック６１、上横枠４と右縦枠３とを接続する第２のコーナーブロック６２、右縦枠３と下横枠５とを接続する第３のコーナーブロック６３、及び、下横枠５と左縦枠２とを接続する第４のコーナーブロック６４のうち、少なくとも２つのコーナーブロックを、互いに同一形状を有する、または、互いに鏡像形状を有する構成とする。【選択図】図１
