Abstract:
An apparatus for constructing a concrete block mat consisting of unit concrete blocks interlocked together in the form of a mat by way of connections for adjacent interlocking members of the unit concrete blocks, comprising:a frame including a plurality of laterally spaced longitudinal beams, and a plurality of longitudinally spaced lateral beams, each lateral beam being arranged between adjacent ones of the longitudinal beams and fixedly mounted at opposite ends thereof to the adjacent longitudinal beams;a plurality of frame connecting wires each fixedly mounted at one end thereof to an upper surface of the frame at a desired position and connected at the other end thereof to a crane wire, the frame connecting wires serving to lift the frame in a horizontal state when the crane wire moves upwardly;a plurality of block mat connecting wires each fixedly mounted at one end thereof to the frame at an associated one of longitudinally and laterally spaced positions, each of the block mat connecting wires extending at the other end thereof through a desired one of the block interlocking members of the concrete block mat while being locked to the frame, the block mat connecting wires serving to lift the concrete block mat in a horizontal state when the frame moves upwardly;locking means for locking the other end of each of the block mat connecting wires to the frame; anda lock releasing means for releasing the locked state of each of the block mat connecting wires,wherein the locking means comprises:an eye formed at the other end of each of the block mat connecting wires;a plurality of guide members mounted to the frame at a plurality of longitudinally and laterally spaced positions in such a fashion that they extend vertically through the frame, respectively, each of the guide members having a vertical guide passage;a plurality of locking holes formed through the frame beneath the guide members, respectively; anda plurality of locking members each fitted in an associated one of the guide members in such a fashion that it slides vertically along the vertical guide passage of the associated guide member between a locking position where a lower end thereof is engaged with an associated one of the locking holes via the eye of an associated one of the block mat connecting wires, thereby locking the associated block mat connecting wire, and a lock releasing position where the lower end is disengaged from the associated locking hole, thereby releasing the locked state of the associated block mat connecting wire.
