<p>PURPOSE: To pivotally support a porous concrete block on laminae with its major side surface set downward, then clamp all concrete blocks in a row to be separated from above while using a clamping force and retaining the clamping force applied to a row of concrete blocks in contact with the row to be separated while in movement and cut the row of concrete blocks and thus enable the concrete blocks to be cut without any difficulties. CONSTITUTION: The porous concrete body K of an outermost side is given as one having a thickness (d) and the intermediate porous concrete body K' is given as one having a thickness d'. The concrete body K is disposed on laminae 4, 4' moving along a guide rail 3 through pedestals 7, 7', while the concrete body K' is disposed on the lamina 4 through the pedestal 7. Further, the concrete bodies K, K' are pressed by clamping plates 26, 27. In this case, the clamping plate 26 is moved in synchronization with the first and the second lamina 4 and the clamping plate 27 is fixed as it is located. Consequently, the cut concrete bodies K, K' are separated from each other without falling down from their adjacent faces. Thus the separation action is likewise repeated so that it is possible to separate the concrete bodies K, K' of arbitrary thickness in the transverse direction without falling down.</p> |
