Placing machine for concrete wall casting - has vibrating chute mounted above moulding board on movable carriage to feed concrete to U-shaped frames

摘要

The concrete placing machine comprises jacks arranged in line along a wall to be erected, and U-shaped frames mounted on these jacks and connected with each other by scaffolds. Driving carriages are disposed on the scaffolds for movement and each carries a feed hopper, a moulding board, and a concrete compactor. At least one of the moulding boards is provided with a drive for moving it in the direction transverse to the line of arrangement of the jacks. The concrete compactor is constructed in the form of a vibrating chute positioned under the feed hopper and above the moulding board and provided with a vibrator for oscillating this chute along the direction of movement of the moulding board.
