The invention relates to the production of precast concrete and can be used in the manufacture of reinforced concrete hollow core panels.

The purpose of the invention is to intensify and reduce the energy intensity of heat treatment of reinforced concrete hollow panels.

FIG. 1 shows the installation, plan view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 1 (loading / unloading zone); in fig. 4 is a diagram of the winch loading area and unloading.

The installation for thermal treatment of reinforced concrete hollow panels, carrying out the process according to the rotor-conveyor scheme, contains an annular chamber 1 and a loading-unloading zone 2. The shaping post contains swivel beads 3, hollow cores 4 and paver 5. The loading / unloading zone is equipped with a winch 6. Radially arranged inside the chamber are groups of heaters 7, which on one side rest on the transverse side 8 of the carriage 9 with the removable pallet 10 and product 11, Another is rigidly embedded in the inner movable annular wall 12. An annular overlap 14 is supported on this wall by means of an annular slide support 13. The bridges 15 connect the heaters to the electric boards 16, which by means of sliding taps box openers 17 are connected to a common ring troll 18 and a power cable 1C running to the central support 20. The electrical boards are mounted on brackets 21 and equipped with limit switches 22 for the automatic heater activation circuit, which also includes a stop 23. Stand

The company floor 24, which saturates the radial sections of the track 25, is supported by the rollers 26 on the circular rails 27 and is provided with a rim 28 with a transmission, for example, a chain 29, and an electric drive 30.

To eliminate electrical contact of the heaters with concrete in the event of their possible deflection when inserting products into the voids, the ends of the heaters can be provided with dielectric tips.

The device for heat treatment of reinforced concrete hollow panels works as follows.

From the chamber 1 to the loading-unloading zone 2, the cart 9 with the removable pallet 10 and the heat-treated product 11 is moved. With the help of a winch 6 the cart 9 is moved in the radial direction along the rails 25 to the molding zone. In this case, the heaters 7 are supported on board 8 of the carriage 9. With the last crane, the pallet 10 is removed with the product 11 and sent to the demolition. A new pallet 10 with fittings is placed on the trolley 9.

 Putting the swivel beads 3 into a vertical position and pushing the emptying machines 4 onto the trolley 9 4. The concrete paver 5 serves the concrete mix and molds the product using, for example, a surface vibrator mounted on the concrete paver 5. After forming, emptying the emptying 4, discharging the empty side 3 , and the cart 9 rolls with a winch 6 on the heaters 7.

The rotary floor 24 supported by the rollers 26 on the circular rails 27 is rotated by means of the rim 28 from the front 29 and the electric drive 30 by one step. The freshly molded product is inside chamber 1. The limit switch 22 of the electric board 16 of this group of heaters comes into contact with the stop 23, as a result of which the voltage is applied to the heaters 7.
