Abstract

The invention relates to the construction, in particular, for the manufacture of hollow-core reinforced concrete building products, floor slabs. The purpose of the invention is to improve the quality of the product by intensifying the compaction of the concrete mix during molding with simultaneous sealing of the ends of the products. The installation for forming multi-hollow building products comprises a base 1, a pallet 2, a boring rig 3, a carriage with waste holders 5 fixed on it, rigidly connected to each other in the tail part by a vibroblock. The installation has an additional vibration block mounted on the base, made in the form of oscillations 9 mounted on the frame of the exciter 9 and taper guides 12 for accommodating the free ends of the void formers 5 and the hopper 13 for feeding the concrete mixture to the cylinders, with the pistons kinematically connected to the carriage. 4 il.

The invention relates to construction and is intended for the manufacture of hollow-core reinforced concrete building products, in particular floor slabs.

The aim of the invention is to improve the quality of the product by intensifying the compaction of the concrete mix during molding with simultaneous insertion of the ends of the product.

FIG. 1 shows an installation for forming multi-hollow building products in the working position, side view; in fig. 2 is the same, top view in FIG. 3 is a section A-A in FIG. 2; n FIG. 4 shows a coupling element for cylinders and pistons with a carriage.

The installation for forming multi-hollow building products contains a base 1, a pallet 2, a boring equipment 3, a carriage 4 with hollow-forming agents 5 pivotally attached to it, rigidly connected to each other in the tail section by the vibroblock 6, an additional (vibrating block 7, filled in the form of mounted on frame 8 of the exciter 9 oscillations, cylinders 10 with pistons 11 and tapered guides 12 for accommodating the free ends of hollow cores 5, and a hopper 13 for feeding concrete mixture into cylinders 10. The latter have slots 14 through which the piston and 11 are interconnected by reinforcement 15, which through a system of blocks 16 and tg 17 is connected with gears 18 having a common shaft with gear wheels 19 located on the base 1 and I have the opportunity to engage with gear racks 20, mounted on the carriage 4.

The installation works as follows.

A crane 2 is mounted to the supports 21 (Fig. 1), then the landing gear 3 is fed. After what the carriage 4 pulls the void formers 5 onto the boros nest 3 through the guide rollers 22 and through 5 open ends thanks to the openings in the boron 3. the taper guides 12 of the cylinders 10 are wedged in the additional vibration block 7 (Fig. 3). Then the armature is placed and the concrete mixture is fed both into the mold formed by the pallet 2 and the airborne rig 3, and into the bunker 13 of the additional vibroblock 7 (Fig. 2)

As the form is filled with concrete, the vibration exciters of the vibroblock 6 and the vibration exciter 9 of the additional vibroblock 7, which through the frame 8 transmit vibrations to the free ends of the formers 5. Thus, thanks to the excitation forces applied through the tail and free ends of the emptying 5, the latter oscillates uniformly throughout length with vertically directed vibrations, allowing to achieve high-quality compaction of the concrete mix over the entire area of the form. During operation of the additional vibroblock 7, the concrete mixture from the hopper 13 enters the cylinders 10 and is compacted there. After molding the carriage

4, by moving to the left (Fig. 1), extracts the void-forming 5 from the additional vibroblock 7 and the boring equipment 3, with the toothed strips 20 attached to the carriage 4, the length of which corresponds to the stroke of the pistons 11, which engage with gear wheels 19 having a common shaft with gear 18, which, through the bars 17, the system of blocks 16 and the valves 15, through the slits 14 in the cylinders 10, drive the pistons 11 (FIG. 4). The pistons 11 push the concrete plugs molded into the cylinders 10 and feed them through the grooves 23 into the holes of the product. As the carriage progresses, the 4 straps 20 are disengaged from the cog wheels 19. When the holders

5 are removed, remove the rigging 3, and then the pallet 2 with the molded product is transferred to the finishing station. When the cycle is repeated, the gears 19 rotate in the opposite direction and, accordingly, the pistons 11 return to their original position.
