FIELD OF THE INVENTION This invention relates to the production of multi-hollow core panels and 4M-H fibrrb is used in factories of the construction industry.

The purpose of the invention is to expand the operational capabilities of the form and reduce material consumption.

In FIG. 1 shows a shape, section: in Fig.2 is the same, a top view.

The form consists of a pallet 1. longitudinal flanges 2, end flanges 3, stops of a pallet 4, a separator 5, a base of a splitter b, a flange of a splitter 7. of the stops of a splitter 8. bar 9 and tensile reinforcement 10.

Overlap panels are made as follows (products shorter than the main one).

In the prepared form with open longitudinal 2 and end 3 sides, a separator 5 is installed with an open side 7.

From the unformable side of the separator 5 between the stops 4 of the pallet 1 and the stops 8 of the separator 5, the links 9 are installed (i.e., the position of the separator 5 along the length of the tray 1 is determined by the links 9, the length of which is in turn determined by the length of the molded product).

After that, from the molded side of the separator 5 to the stops 4 of the pallet 1 and stops 8

spacer 5 sets tensioned reinforcement 10 of the molded product. Then, the board 7 of the separator 5 and the sides 2 and 3 of the mold are closed and the mold (moldable part) is filled with concrete mixture according to the existing technology.

After heat treatment, the sides 2, 3 and 7 of the mold and the separator 5 are opened. The outlets of the tensile reinforcement 10 are removed, and the rods 9 remain. Then the mold is cleaned and washed off. The cycle repeats.
