To efficiently cut, with one hand, an edge of a waterproof sheet which is easy to carry and is located on the upper side at a work to form a wrap part of the waterproof sheet at a corner between a vertical wall surface and a floor surface of a rooftop of a building or at a corner between vertical wall surfaces.SOLUTION: A lap joint cutter comprises: a main body 3 having a grip at an upper portion and rotatably supporting a round blade 2 at a lower portion; a guide 4 provided laterally and removably projecting on the side of the main body 3 and having a constant projecting width along the longitudinal direction of the main body 3; and an underlayment 5 provided below the main body 3 and forming space portions S1, S2 into which an edge of a waterproof sheet can be inserted between the lower end of the main body 3 and itself. In the space portions S1 and S2, a cutting edge portion of the round blade 2 is positioned so as to be able to cut the edge of the waterproof sheet.SELECTED DRAWING: Figure 1
【課題】持ち運びが便利で、建物の屋上の縦壁面と床面との間のコーナー部あるいは縦壁面と縦壁面との間のコーナー部において防水シートのラップ部分を形成する作業において、上側に位置することになる防水シートの端縁を、片手の作業で効率よく裁断する。【解決手段】上部に握り部を有し下部に丸刃２を回転可能に支持する本体３と、本体３の側部に側方に突出するようにかつ取り外し可能に設けられ本体３の長手方向に沿って一定の突出幅を有するガイド４と、本体３の下方に設けられ本体３の下端との間に、防水シートの端縁を差し込み可能である空間部Ｓ１，Ｓ２を形成する下敷き５とを備える。空間部Ｓ１，Ｓ２内に、丸刃２の切り刃部分が、前記防水シートの端縁を裁断可能に位置している。【選択図】図１
