Abstract

The invention relates to the manufacture of precast concrete and reinforced concrete products and allows for improving the quality of the manufactured products by increasing their flexural strength. This is achieved due to the fact that in the device for molding articles from steel fiber concrete, the winding of the electromagnet is made up of a composite of upper half-rolls 9 fixed on the smoothing plate 2, and encompasses their form 1 of the lower half-turn 10 in contact with each other. The ends of the uppermost half-turns 9 are connected to a direct current source. 3 il.

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

The purpose of the invention is to increase the quality of manufactured products by increasing their flexural strength.

FIG. 1 shows the proposed arrangement, a general view; in fig. 2 is a section A. to FIG. one; in fig. 3 is a diagram of the connection of the electromagnet windings.

The device consists of mounted

in them, 9 semi-turns of the windings of a composite electromagnet and fibers in an electromagnetic field are oriented in the longitudinal direction. The smoothing plate 2 5 compresses the mixture. As the bunker 3 advances with the smoothing plate 2 and upper half-wrinkles 9 along the form, the next contacts AND the lower half-winglets 10 are closed, and behind the smoothing plate 2 there remains a compacted mixture with the orientation and i UL: ideH; - Fitted in the longitudinal direction of the two plates 2 connected to the horizontal fibers,
