Description

one

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

The purpose of the invention is to increase the contractual device.

Fig. 1 schematically shows a mold for the manufacture of products from concrete mixtures, a general view; in FIG. 2, the same plan view; FIG. 3 is a section A-A in FIG. 2; figure 4 - node fig.Z; figure 5 - view B in figure 4.

The form consists of a pallet 1, to which end flanges 3 are attached with the help of hinges 2, kerchiefs 4 are attached to the ends of pallet 1, on which supports 5 are installed to receive tension from reinforcement 6 and comb 7 with grooves 8 made segment in the longitudinal and trapezoidal in cross section, and the grooves 8 are arranged symmetrically slots m 9 face

beads 3. The grooves 8 are filled with refractory material Y.

The form for the manufacture of products from concrete mixes works as follows.

During the formation of the product, the cement milk formed during vibration flows into the gaps between the tension fittings 6 and the slot 9 in the face side 3 and flows out due to the fact that the stops 5 are taken out of the pallet 1,

After heat treatment of the product, the mold goes to the post-demoulding station, where the end flanges 3 are opened on the loops x 2, and the fittings are cut 6 once around the end of the product, and the refractory material located in the recesses 8 preserves the comb 7 during the cutting fittings 6 electric welding. The product is then removed from tray 1,
