the shields 3, the drives for moving them 4 with the lead 5 and the follower vypressovshchiki 6, synchronizers 7 and the end beads 8. The base is

5 a metal frame with beams for fastening the vibration shields and the core, as well as fastening the drive 4 of the hydraulic cylinder 9 for the movement of the vibration shields. The core of the box section inside between the walls 10 forms the cavity of the heat chamber, in the wall of which a layer of thermal insulation is laid. Notches 11 are provided for facing with a tile on the core. Each of the vibration shields is made in the form of a rigid frame made of iron bar, covered with a metal sheet. Outside, each vibration shield is protected by a layer of thermal insulation and equipped with a vibrator 12. Drive 4 moves

 vibroshields 3 includes a hydraulic cylinder 9, levers 13 and provides deflection and locking of each of the vibration shields supported on racks 14 by means of hinges 15. Locking vibrating shields is provided by positioning the levers 13 on a common axis and switching to a dead point. Each of the leading vypressovschiki 5 is made in the form of a two-armed lever 16 with the support leaning

part of the joint 15 and with tgami 17 and 18 at the ends. On the double-shouldered lever 16 for separate stripping and pressing out of the product, an oval hole 19 is provided in the vertical direction for connection with a pull of 17 and

25

horizontal direction oval hole 20 for connection with a pull 18, rigidly connected to the Pallet 21. Each of the press brackets 6 is also made in the form of a two-arm lever 22 with a leaning middle part on the hinge 15, with a pull 23, rigidly connected to the pallet 24. Each synchronizer 7 made in the form of a two-arm lever 25 with a middle part supported on the hinge 26 and pivotally connected to one of the ends of the adjustable bar 27. The other end of the rod 27 is connected to the two-armed lever 22 of the driven vypressovschika 6. The other end of the double-arm lever 25 is ball The niryo is connected to the two shoulders of the lever 16 of the leading vypressovschika 5. Each end side 8 is hinged on the servot and is made with the possibility of manual reclining. The molding cavity of the installation for the manufacture of volumetric elements of the U-shaped cross-section provides the possibility of horizontal arrangement of the overlap plate | walls located vertically downward between the vibration shields 3 and 28 and the core 29. At the same time, the walls can be unevenly high.

In this version of the installation, each of the leading vypressovshchiki 5 is made similar to the one considered. Each of the driven vypressovschiki 30 is made in the form of a two-arm lever 22 with a middle part supported on the hinge 15 and provided with a length-adjustable pull-rod 31 rigidly connected to the pallet 32. Accordingly, each synchronizer 33 is made in the form of a two-arm lever 25 with the middle part supported on hinge 26. At the same time, one end of the two shoulders of the synchronizer lever 25 33 is pivotally connected to the driver output 5, and the other end of the lever 25 is connected to the follower extractor 30. The end bead 8 is also made similarly to the first installation variant.

The third installation option is intended for the manufacture of U-shaped volumetric elements in plan, formed in a vertical position between the vibration shield 34 and the core 35. Vertical and horizontal technological slopes are provided to facilitate stripping. Each of the leading vypressovshchiki 5 and synchronizers 33 are O 5 0 5

not similar to the above. Each of the driven vypressovshchikov 36 is made (in the right or left version) in the form of a Z-shaped mechanism consisting of a single-arm lever 37 pivotally connected to the synchronizer 33 and rigidly fastened to the shaft 38 with the help of pins 39. The other end of the shaft 38 is also rigidly fastened with the second one-arm lever 37, hingedly connected with a length-adjustable pull-rod 31, rigidly connected to the pallet 40. The end flanges 41 close the molding cavity with the possibility of tilting, and lock it manually.

A paired installation for the manufacture of volumetric elements of the L-section variant operates as follows.

The vibration shields 3 are deflected by the drive 4, and the end flanges 8 are manually deflected, then the molding surfaces are cleaned and lubricated. After installation of the reinforcement cages, the vibration shield 3 and the bead 8 are closed, and the resulting cavity is fed and the concrete mix is compacted by the vibrators 12. Then the concrete mixture is fed and compacted with a vibrating rail, forming shelf surfaces. Warm up the product with steam or other coolant.

Stripping with the extrusion of the product at the end of the heat treatment is performed in the following sequence. For demoulding, the products are deflected by the vibration guards 3 by the drives 4, and the end flanges 8 by hand. At the same time, gaps in the oval holes 19 between the taps 17 and the double-arm levers 16 of the vypressovshchiki 5 are first selected. With the further deflection of the vibration protection boards 3 ti 17 act on the vypressovshchiki 5 and through the synchronizers 7 on the driven vypressovshiki 6. At the same time, the trays 21 and 24 are directed up at the same time, the product is opened from the core 2. The finished product is removed by a crane and sent to the warehouse.

An apparatus for manufacturing volumetric elements with a U-shaped cross section with vertical walls works as follows.

Initially, vibratory shields 3 and 28 are deflected by drives 4 and the end beads 8 are manually retracted.

Cleaning and lubrication of the molding surfaces is carried out in the same way as set

for the manufacture of bulk elements L-shaped.

An installation for producing P-shaped products in terms of cross-section during molding in the vertical position works as follows.

Initially, the vibration shield 34 is driven in the same plane by the actuator 4, and the end flanges 41 are manually retracted, the molding surfaces are cleaned and lubricated, - After the reinforcement cages are installed, the vibration shield 34 with the core is closed, the flanges 4 are closed and the formed cavity is fed and upsetted with vibrators 12 concrete mix

Heat treatment of the product is analog described.

The removal of the extrusion of the products at the end of the heat treatment is carried out in the following sequence. To dismantle the product, the vibration shield 34 is deflected by the actuator 4, the sides 41 are deflected manually. At the same time, gaps in the oval holes 19 between the ends 17 and the double-shouldered extruders 16 are selected. A further deviation of the vibration shield 34 ti g 17 affects the expressors 5 through the synchronizers 33 and the driven vypressovshchiki 36. Further work proceeds similarly to the first variant.
