Description

(54) DEVICE FOR FORMING AND FINISHING PRODUCTS FROM CONCRETE MIX

one

The invention relates to the field of concrete products manufacturing and paving.

Closest to the present invention is a device for molding and finishing concrete products, containing a bunker mounted on a frame with a vibrator mounted on the front and in the rear wall of the rear wall and a roller connected to the mechanism of vertical movements and mounted after the last vibration sealing device 1.

A disadvantage of the known device is a large one - the laboriousness of manufacturing products due to a large amount of concrete mixture flowing into the gap between the bottom of the mold and the lower edge of the front wall of the bunker because of its thixotropic liquefaction, and and a transverse reinforcement mesh, which leads to the necessity of fixing them before the device starts operating and thereby causes an increase in labor costs.

The purpose of the invention is to reduce the complexity of manufacturing products.

This goal is achieved by the fact that a device for forming concrete products containing a bunker mounted on frame 5 with a vibrator wall mounted on the front and in the back of the rear wall and a roller connected to the mechanism of vertical shifts, and mounted behind the last vibJQ the device is equipped with a movable stop and an elastic plate in contact with it, mounted on the lower edge of the front wall of the bunker.

The drawing shows schematically a device for forming and finishing of 15 products from a concrete mix, a section.

The device for molding and finishing concrete products consists of a frame 1, on which a hopper 2 with a mounted vibrator 3 on its front wall, a roller 4 with a drive 5, a mechanism 6 of vertical movement of the roller 4 installed in the rear wall of the bunker 1, and vibrating compaction device 7. At the lower edge 8 of the front wall of the hopper 2 there is fixed elastic plastic 296, in contact with the movable support 10 and the rod 11 of the longitudinal reinforcement. A device for forming and finishing products from a concrete mixture works as follows. After the hopper 2 is filled with the concrete mix, a mounted vibrator 3 is turned on, under the action of which the concrete mixture thixotropically liquefies and fills form 12, and when moving the hopper 2 and form 12 relative to each other, roller 4 distributes the concrete mix according to form-, me 12 and profiles a layer of a given thickness, and the plate 9 with the lower edge slides along the rods 11 of the longitudinal reinforcement and contributes to the uniform distribution of the mixture in the mold 12. The final compaction of the product and smoothing of its surface is performed by vibrating with a sealing device 7. At the end of laying the concrete mix in the mold 12, the stop 10 presses the plate 9 against the roller 4 and thereby cuts off the concrete mix in the bunker 2. The use of the proposed device for the molding and finishing of products from concrete mixtures in the industry of precast concrete and reinforced concrete will reduce the complexity of the manufacture of products and improve the working conditions of service personnel. Apparatus of the Invention A device for forming and finishing products from a concrete mix, containing a bunker mounted on a frame with a vibrator placed on the front and in the back of the rear wall and a roller connected to the mechanism of vertical movements and mounted behind the last vibro-compacting device, characterized in that the purpose of reducing the complexity of the manufacture of products, it is equipped with a movable stop and in contact with it an elastic plate fixed on the lower edge of the front wall of the hopper .
