In strontelnoy technology known attempts arykrovi tsvnentshh concretes segments of thin steel and iitey-hair. These attempts did not lead to real results, since no acceptable method was found for introducing steel filaments into the mass of eton.

In order for reinforcement of steel filaments to work affectively on stretching in the mass of concrete or mortar, the following conditions must be met: the distribution of steel hair segments in the mass of concrete (solution wedge) must be regular and in each section there must be no less than the calculated amount of apMaiypH ; the segments should be straight and oriented in the direction of the acting tensile forces or close to the direction of the atom1 the length of each segment should be such that with the maximum perceived force of the thread it will not be pulled out on the concrete (mortar).

The purpose of the present invention is to create a device for making sheet materials from cement paste or mortar (EFI Drupi plastic), reinforced with segments of steel (or other) hair, oriented in predetermined directions.

In the JUH device described here, a mixing drum is designed, it has a schrodol slot, overlapping; damper and oredaznachennyi for downloads.

ki into the drum of the hair segments with preservation of their direction along the axis of the drum and delivery of the finished mixture to the vice band

The inner surface of the drum on the side opposite to the slit could be made wavy in order to maintain the direction of the hair segments in the solution while it is being mixed.

One of the axles of the mixing drum can be made hollow and intended to connect the drum cavity to the compressor unit in order to deliver the finished mixture with compressed air pressure.

FIG. I depicts a mixing drum, a longitudinal section; in fig. 2 - the same, cross section; in fig. 3 - the same, when loading hair into the drum; in fig. 4 - the same, when mixing the mixture; in fig. 5 the same, when issuing the finished mixture in the forgg; in fig. 6 shows an embodiment of a forcing device.

The hollow drum of a cylindrical ELE faceted form is made of EZ low-melting iron E has the entire length along the growing gap I, which with the help of the flap 2 opens to the desired height or completely closes. The drum rotates around its axis, with one of its axes 3 made in the form of a pipe connecting the drum cavity to the compressor unit. The drum drum walls in the part of the semicircle opposite the slit I are provided with waves 4 (ILE blades) with ridges directed along the forming cylinder.

Cement mortar (ish dough) LEB its components (cement, water, sand) in a known optomeal sequence established by experiment, are loaded into the drum through a slit opened to the required size using an appropriate funnel. Then the slot is completely closed, the E drum is rotated.

After thoroughly mixing the solution, the drum is stopped with a slit up, the latter is opened and the cassette 5 is inserted into it (see FIG. 3), filled with segments of steel hair in a pre-measured ELE weighed quantity. The cutting of the hair is positioned in the cassette in the longitudinal direction. In the lower part of the cassette, it has a narrow slot 6, which can be opened and closed, operating on top of the mechanism 7.

When opening the gap, 6 segments of steel hair gradually pour out - 2 - .68466

c into the solution, moreover, they do not lose their orientation. At this time, the drum can be rocked on the axis so that the falling threads cover the surface of the solution with a wider strip.

To speed up the process of unloading the cassette to its wall, you can attach a small vibrator, which served to seal the steel hair when loading it into the cassette.

After the hair is poured into the drum, the cassette is removed, the slot -1 is closed and the drum is rotated again and evenly distributes the hair segments in the mass of the ELI dough solution (see Fig. 4). When mixed, the hair sections roll over with the solution and stick around with it, while maintaining their original orientation. Wavy lobes contribute to the mixing and orientation of the hair.

Another sequence of the process may be more expedient: backfilling of dry components in a mixture with steel hair, rotation, addition of water, rotation. The optimal mass consistency is established by experience.

After a homogeneous mass of the solution is heated in the drum with the hair sections evenly distributed in it, the drum is stopped by the internal storage slit, and the cavity is connected to the compressor unit. By the action of compressed air, the solution is squeezed out through an open slit in the form of a continuous film of raw fibrous cement mass of relatively uniform thickness (see Fig. 5) and enters the vacuum-forz; g consisting of a mesh or a perforated sheet 8 and a cavity 9 attached to BaiQryM-pump. By expanding the film in several layers, a sheet of the required thickness is produced. At the same time, excess moisture is drawn from the sheet by vavuumination and is compacted.

The obtained sheet of the required thickness is subjected to pressing or rolling for further compaction, and, if necessary, appropriate molding, stamping and other known types of processing. Acceleration of hardening and increasing the strength of the sheet is carried out by conventional methods in an aqueous medium, steaming, autoclaving, etc.

Another variant of the process of forming sheet material is shown in FIG. 6. A film of material emerging from the slot I of the drum is wound on

a rotating cylinder 10, the surface of which is provided with a thick network of holes, while the internal cavity is connected to a vacuum pump. In the first sector, the film passes under the roller I, which regulates its volume. In this case, the cylinder bores are closed with a fixed sector 12. JSfuiee sheet is compacted using press rollers 13 and 14. The sheet, brought to the required thickness, is cut through the generator and passes to the conveyor 15, from which it goes to the subsequent processing.

It is also possible to remove the fibrous-cement layer from the cylinder in the form of a thin-walled tube, which should be detachable in 10. The film is wound across the entire length of the cylinder, for which the use of a drum of the appropriate length, or a strip along a helical line, the drum must then have a translational motion associated with the rotation of the cylinder.
