The drive swivel grips 6 are mounted on the synchronizing shaft 7. The swivel grips 6 are connected by means of a hinge 8 with a drive 9, for example, a hydraulic cylinder mounted by means of a hinge 10 on the foundation 11. The hinges 13 are fixed to the swivel grips 6. Grips 6 and 13 are interconnected by a hydraulic cylinder 14, fixed to them with the help of hinges 15 and 16. On the pallet 2, stops 7 are mounted.

Supports 18 and 19 are fixed to the pivot grips 6 and the pallet 2 to prevent the pallet 2 from moving when it is raised to a vertical position. The pallet 2 has roller supports 20 placed on rails 21 and 22 mounted on a foundation 11 and guides 23 mounted on grips 16. Guides 23 are located at discontinuities of guides 22 located on both sides of the aforementioned grippers .

On the upper edge of the vibration shield 5, guides 24 are mounted, mounted on the upper end of the vibration shield 5 and protruding beyond the lateral edges of the mold. A guide 25 is placed in the guides 24 for laying a concrete mix, consisting of a U-shaped body 26, guide rollers 27 and deflecting rollers 28, on which elastic tape 29 is stored. On the body 26 by means of hinges 30 there are vibro skis 31 The rollers 27 and 28 are mounted on the housing 26 by means of axles 32. The elastic tape 29 is fixed at the ends of the vibration shield 5 using tension devices 33. The elastic tape 29 is stored in the rollers 27 and

28 and around the bunker 4 from the outside.

The hopper 4 for feeding the concrete mixture is placed in the guides 34 of the housing 26 by means of the guides 35.

The upper edge of the boring equipment 3 stands for the upper end of the vibration shield 5 and form between them an opening 36. The output window of the bunker 4 is located in the opening 36.

Shaft 7 is movably mounted in brackets 37. Boring equipment 3 has shaping liners 38. Elastic tape

29 to prevent movement from the rollers 27 and 28 have protrusions 39, and the rollers correspond to the protrusions of the groove 40.

A plant for the vertical molding of concrete products works as follows.

From the decomposed installation (Fig. 2), the mold consisting of the pallet 2 and the rigging 3, with the finished products, is moved along rail guides 21.22 and 23 mounted on the foundation 11 for further technological operations.

In its place, a new form is moved, for example, a charged preload reinforcement (not shown in the figure). In order to form an upper relief surface (for example, longitudinal notches), shaping inserts 38 are placed in a mold.

The mold is mounted on a vertical forming station in such a way that the roller supports 20 nearest to the installation are located on the guides 23 of the grippers 6. The hydraulic cylinders 14 are turned on, which, turning around the hinges 15 and 16, turn the grips 13 around the hinges 12. At the same time, the grips 13 are in t in engagement with the stops 17. Include hydraulic cylinders 9, which, turning around the hinges 8 and 10, rotate the claws 6 around the synchronizing shaft 7, movably mounted in the brackets 37, and hence the shape in the vertical position. While the stops 18 and 19 prevent the displacement of the form in a vertical position. The upper edge of the rig 3 protrudes beyond the upper end of the vibration shield 5, and an opening 36 is formed. Then, guide 35 of the bunker 4 to feed the concrete mix, for example, a cantilever paver (not shown) is inserted into the guide 34 of the concrete mixers 25. When this output window of the hopper 4 coincides with the opening 36, Include paver, from which the hopper 4, and then into the form of concrete mix. At the same time, the paver will horizontally move the device with the bunker 4 along the guides 24. At the same time, using a vibrolan 31, the concrete mix is compacted through an elastic band 29. When moving the device 25 along the rigging 3, the elastic band 29 deviates from the shape of the bunker with the help of rollers 27 and 28, moving the projections 39 along the grooves 40.

After the form is completely filled with the concrete mixture, steam shield 5 is supplied to the steam jacket and the products are preheated.

After the preliminary heat treatment, the installation is dismantled in reverse order and the cycle is repeated.
