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

The purpose of the invention is to reduce the labor intensity by providing immediate dismantling.

FIG. Figure 1 shows schematically the proposed device for the formation of holes in concrete products for flush mounting loops, general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - the proposed device plan; in fig. 4 shows a form with a device mounted thereon for forming holes in concrete products for flush mounting loops, a transverse section; in fig. 5 - form with sand filled hole products, a longitudinal section.

A device for forming holes in concrete mix products recessed mounting hinges consists of a rotary hole former 1 with a slot 2 and a handle 3 placed in a cage formed by connected cross member 4 cheeks 5 with grooves 6 for passing the mounting loop 7, on the outer surface of the cheeks 5 rigidly fixed position of the rotary hole formers 1 in the form supported

beads of the form of 8 horizontal holders

9 with stops 10 at the ends.

The device operates to form holes in concrete mix products for mounting loops as follows. Before installing the device on the form 8, the cage between the cheeks 5 is inserted from the bottom through the grooves 6 up to the stop into the cross member 4 by the top of the mounting loop 7, and then turning the caster 1 into the slot 2 by turning it clockwise, while the height of the mounting loop 7 enters the slot 2 The rotary moon former 1 is fixed in the holder between the cheeks 5 by resting its lower part on the web 11 and the handle 3 on the upper edge of the holder. After assembling the device, together with the mounting loop 7, install holders 9 on the edges of the form 8, so that the stops

10 Waxed in the inner cavity of the latter. Then form 8 is filled with concrete

0 with a mixture of 12, it is compacted and the lunar former 1 is removed by turning it counterclockwise. The cavity formed in the product is filled with dry sand 13, the holder is removed and the product is transferred to a heat and moisture treatment.
