Description

one

The invention relates to the production of prefabricated concrete and reinforced concrete.

The aim of the invention is to provide the possibility of manufacturing thin-walled products.

FIG. Figure 1 shows schematically an installation for forming long hollow products from concrete mixtures, general view | in fig. 2 is a view A of FIG. one.

The installation for forming long hollow-out products from concrete mixes consists of a horizontal-movable frame 3 supported on a pallet 1 by means of rollers 2 with a feed buoy mounted on it. rum 4, longitudinal sides 5 connected to the ends of the smoothing plate 6, forming a U-shaped nozzle in cross section, connected to the rear wall of the feed hopper 4, and nozzle parallel to the longitudinal axis of the horizon horizontally in the U-shaped cavity in the cross section. the hollow cores 8, bent by the front parts bent obliquely upwards, are placed with the help of hinges 7, lateral dampers 9 and a device for feeding and placing the reinforcement in the form of a roll holder 10 of the reinforcing mesh 11.

In the front part of each void-forming, bent obliquely upwards, vibration exciter 12, is installed, and the front wall 13 of the feed bin 4 is connected to its side walls 14 in the zone of the loading window

with the help of the hinge 15, and the U-shaped in cross-section of the nozzles is made turning around the hinge 16.

The installation works as follows.

Before starting the delivery of the concrete mixture 17, reinforcement 1 and 18 of the reinforcement bars 18 and 19, respectively, of the bottom plate and product walls are made on the pallet. Then, a roll of reinforcing mesh 11 is installed into the roll holder 10, the end of which is passed through the slot 20 in the front wall 13 of the feed bin 4 and, when suspended in the nozzles, is fixed on the front end of the tray 1 (not shown).

Then, the concrete mix 17 is loaded into the feed bin 4, vibration exciters 12 are turned on, and as the entire cross section of the cavity is filled, the nozzle is moved by a drive (not shown) to the horizontal frame 3 along the tray 1.

When moving the horizontal-movable frame 3, the concrete mixture 17 under the influence of vibration exciters 12 moves along the front bent on ;. the top of the front parts of the void formers 8, forming the guides in contact with the reinforcing mesh 11. As the horizontal-movable frame 3 moves, the molded product, which is the bottom plate on the pallet 1.
