JOINT CUTTING DEVICE
To provide a joint cutting device capable of holding a slate without a gap and of accurately forming a straight joint.SOLUTION: A joint cutting device 1 for forming joints in a concrete pavement comprises: a pair of holding plates 10, 10 holding a slate 3 inserted into a road surface; a pressing plate 20 for pressing the slate 3 from above; and a pressing means 30 for pressing the holding plates 10 against the slate 3. At least one of the holding plates 10 is provided movably in the thickness direction of the slate 3. The holding plates 10 include a vertical plate part 11 in contact with the slate 3; and a horizontal plate part 12 extending outward from the upper end of the vertical plate part 11. The pressing means 30 includes a lateral direction cam mechanism 31 for pressing the holding plates 10 toward the slate 3; and a longitudinal direction cam mechanism 32 for pressing the tip of the horizontal plate part 12 downward.SELECTED DRAWING: Figure 7
【課題】スレートを隙間なく挟持でき、直線状の目地を正確に形成できる目地切装置を提供する。【解決手段】コンクリート舗装に目地を形成する目地切装置１において、路面に挿入されるスレート３を挟持する一対の挟持プレート１０，１０と、スレート３を上から押さえる押えプレート２０と、挟持プレート１０をスレート３に押し付ける押圧手段３０とを備えていることを特徴とする。挟持プレート１０のうち少なくとも一方は、スレート３の厚さ方向に移動可能に設けられており、挟持プレート１０は、スレート３に当接する縦板部１１と、縦板部１１の上端から外側に広がる横板部１２とを備えており、押圧手段３０は、挟持プレート１０をスレート３に向けて押し付ける横方向カム機構３１と、横板部１２の先端部を下方に向けて押し付ける縦方向カム機構３２とを備えて構成されている。【選択図】図７
