TAPE ROLL FOR SLAB TYPE TRACK REPAIR, MANUFACTURING METHOD FOR THE SAME, AND SLAB TYPE TRACK REPAIR FORMWORK INSTALLATION METHOD

To be able to repair a filling layer with good appearance while installing a repair formwork at an appropriate position more quickly and easily when repairing the filling layer.SOLUTION: Provided is a tape roll 40 for repairing a slab type track, that is formed by winding a formwork tape 30 having an L-shaped cross section attached to an upper surface of a roadbed concrete and a side surface of a track slab. The formwork tape 30 comprises: a first base material layer 45 and a second base material layer 46 that are separated from each other in the width direction and extend in the longitudinal direction; a first adhesive layer 38A provided along a side edge region on the surface of the first base material layer 45 (the surface on the formwork surface side) opposite to the second base material layer 46; and a second adhesive layer 38B provided on the back surface of the second base material layer 46. The second base material layer 46 is rolled in a roll shape with the second base material layer 46 inside in a state where it is folded on the front side of the first base material layer 45 along a boundary line 41 with the first base material layer 45.SELECTED DRAWING: Figure 9 【課題】填充層を補修する際に、補修型枠の適切な位置への設置を一層迅速且つ容易に行え、見栄えよく填充層を補修できるようにする。【解決手段】路盤コンクリートの上面と軌道スラブの側面とに貼付されて断面Ｌ字形をなす型枠テープ３０を巻いてなるスラブ式軌道補修用のテープロール４０を提供する。型枠テープ３０は、幅方向に互いに区分されて長手方向に沿って延在する第１基材層４５及び第２基材層４６と、第１基材層４５の表面（型枠面側の面）の、第２基材層４６と相反する側の側端縁領域に沿って設けられた第１粘着剤層３８Ａと、第２基材層４６の裏面に設けられた第２粘着剤層３８Ｂとを有し、第２基材層４６が第１基材層４５との境界線４１に沿って第１基材層４５の表側に折り重ねられた状態で第２基材層４６を内側にしてロール状に巻かれている。【選択図】図９
