Abstract

The invention relates to the production of products from precast concrete and reinforced concrete and allows to intensify the laying and compaction of the concrete mix due to the fact that in the concrete paver the base frame is equipped with fixed 6 and movable 7 drive supports. Traverse 3 is mounted in them in a cantilever manner. The impulse rods 2 are made conical, and the large bases of the hopper 1 and the impulse rods 2 are in contact with resilient elements 10 and the traverse 3, respectively. 3 Il.

This invention relates to the manufacture of precast concrete and reinforced concrete products.

The purpose of the invention is to intensify the laying and compaction of concrete mixtures.

FIG. 1 schematically shows a paver, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

The paver consists of a pyramidal bunker 1 with conical motive rods 2 placed in its cavity along the perimeter and parallel to the inner surface, mounted on the cross-bar 3 connected to the supporting frame 4 on which the oscillation pathogen 5 is mounted. mobile 7 drive supports and guides 8. The carrier frame 4 in its front part is made in the form of a closed conical shell 9, the shape of which corresponds to the shape of a pyramidal bunker 1 installed There is a gap between the pyramidal bunker 1 and the conical shell 9, the size of which is not less than the amplitude of oscillations of the base frame 4. Traverse 3 in plan repeats the internal outlines of the conical shell 9. Between the conical shell 9 and the crosspiece 3, as well as between the conical motive rods 2 and the pyramidal bunker 1 there should be a gap of 40-50 mm, ensuring the passage of a filler with a size of 15-20 mm. The movable drive bearing 7 is moved along the guiding power cylinder 11, and the shutter 12 is moved by the power cylinder 13.

The paver works as follows.

The paver is placed above the mold so that the outlet of the pyramidal bunker 1 is above the mold at its beginning. The cylinders 13 opens the shutter 12 outlet

pyramidal hopper 1. The paver's horizontal movement drive is turned on simultaneously with the vibration exciter 5, while the concrete mixture

due to the oscillation of the motive rods 2, it is separated from the walls of the pyramidal bunker and first falls under the profiled and then under the horizontal part of the supporting frame 4 where its final consolidation is achieved. Options

the vibrations of the motive rods 2 are changed by moving the movable driving support 7 along the guiding 8 power cylinders 11. This changes the length and, consequently, the hardness of the clamped yoke 3, which leads to a change in the parameters of its oscillations. The intensification of the outflow of the concrete mix is facilitated not only by the oscillation of the motive rods 2, but also by the implementation of the bunker 1 with a pyramidal, mounted large base downwards, with a gap on the sidewall.

After the molding process is completed, the outlet of the pyramidal bunker 1 is closed by a shutter 13 and the oscillation pathogen is turned off.
