PROBLEM TO BE SOLVED: To provide an energy-conserving and highly workable cutting device for a concrete wall surface, the cutting device being of a simple configuration that is not massive, offering ease of transportation and handling, allowing a cutter body to be supported horizontally for certain, enabling cutting work to be completed in a short period of time by smoothly moving the cutter body by human power because a load on a rotary blade is small during cutting, capable of cutting an entire periphery at almost a uniform depth with only a small amount of corner portions that are left uncut, and facilitating removal of a concrete basin after cutting.SOLUTION: A cutting device for a concrete wall surface includes a frame part fixed on a periphery of an opening of a concrete basin, and a cutter moving mechanism disposed on the frame part for moving a cutter body along an inner wall of the concrete basin on a horizontal plane. The cutter moving mechanism includes a cutter holding part that holds a cutter body, a parallel slide holding part that holds the cutter holding part slidably in a direction parallel to a side of the concrete basin, and an orthogonal slide holding part that holds the parallel slide holding part slidably in a direction orthogonal to the sliding direction of the parallel slide holding part.SELECTED DRAWING: Figure 1
【課題】簡素な構成で嵩張らず、搬送性、取扱い性に優れ、カッター本体を確実に水平に支持でき、切断時の回転刃への負荷が少なく人力でスムーズにカッター本体を移動させて短時間で切断作業を行え、角部の切り残しが少なく全周を略均一な深さで切断して綺麗な切断面を得ることができ、切断されたコンクリート桝の撤去作業が容易で省力性、施工性に優れるコンクリート壁面切断装置の提供。【解決手段】コンクリート桝の開口部周縁に固定されるフレーム部と、フレーム部に配設されカッター本体を水平面内でコンクリート桝の内壁に沿って移動させるカッター移動機構と、を備え、カッター移動機構が、カッター本体を保持するカッター保持部と、カッター保持部をコンクリート桝の一辺と平行な方向に摺動自在に保持する平行摺動保持部と、平行摺動保持部を平行摺動保持部の摺動方向と直交方向に摺動自在に保持する直交摺動保持部と、を備えている。【選択図】図１
