Abstract
Abstract A concrete placing apparatus 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 positioned along and on both sides of the line of arrangement of the jacks. The apparatus also includes driving carriages disposed on the scaffolds for movement therealong. Each carriage carries a feed hopper, a moulding board, and a concrete compacting means. According to the invention 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. This drive is connected with the moulding board by means of a rod. The concrete compacting means is constructed in the form of a vibrating chute positioned under the feed hopper and above the moulding board and provided with a vibrating means for oscillating this chute along the direction of movement of the moulding board. The vibrating chute is mounted on the same carriage with the moulding board having a drive and consists of two parts attached to each other for extending in the direction of movement of this moulding board, so as to enable varying the passage area of the vibrating chute according to the change in the distance between a respective moulding board and the line of arrangement of jacks.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
237 words
A concrete placing apparatus for casting solid walls, comprising: jacks arranged in line along a wall being cast; U-shaped frames suspended on said jacks; scaffolds connecting said frames and arranged on both sides and along the line of arrangement of said jacks; driving carriages mounted on said scaffolds for movement therealong; a feed hopper, a moulding board and a device for compacting concrete, all the three mounted on each said carriage: at least one of said moulding boards comprising: a drive for transversely moving said moulding board relative to the line of arrangement of said jacks so as to vary a distance between said moulding boards; a rod connecting said moulding board to said drive; said device for compacting concrete being made in the form of a vibrating chute disposed under said feed hopper and above said moulding board, and provided with a vibrating means for oscillating along the direction of movement of said moulding board; one of said vibrating chutes which is disposed on the same carriage with said moulding board having a drive, consists of two parts attached to each other so as to be capable of extending in the direction of movement of said moulding board, one of these parts being connected with said drive of said moulding board for varying a passage area of said vibrating chute depending on the distance between said moulding board and the line of arrangement of said jacks.
