(54) FORM FOR MANUFACTURING PRODUCTS FROM CONCRETE MIXTURES

one

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

The known form for the manufacture of products from concrete mixes, containing transverse beads in the form of restrictive walls with cross-beams, connected by means of interlocked in pairs articulated bars with a pallet, on which sliding longitudinal beams and dividing partitions 1 are installed.

The disadvantage of this form is that it is impossible to manufacture products that have ledges in the upper base surface, which reduces its utilization rate in the conditions of small-scale production of reinforced concrete structures.

The purpose of the invention is to expand the range of manufactured products.

This goal is achieved by the fact that the form for the manufacture of products from concrete mixes, containing transverse beams in the form of restrictive walls with traverses, connected by means of interlocking in pairs of hinge bars with a pallet, on which the sliding longitudinal beams and dividing partitions are installed (: the form of composite ducts with slots to accommodate the dividing partitions, and the restrictive walls are made with clamps angled to

5 horizontal plane.

FIG. 1 shows the form for the manufacture of products from concrete mixtures, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - section BB on

10 of FIG. 2; in fig. 4 — longitudinal coupling element of sectional window openings; in fig. 5 - cutter, cross section.

The form contains a pallet 1, longitudinal sides 2, demoulding mechanisms 3 with offset longitudinal sides 2 and transversal boards, in the form of traverses 4 with restrictive walls 5 fixed to them. The ends of each yoke 4 are connected to the pallet by means of pairs of articulated hinges. Longitudinal dividers 7 are installed between the bounding walls, with removable openings in the form of composite ducts 8 with slots 9 for accommodating

partition walls 7. Each duct 8 has holes 11 in the end walls 10, and the end walls 10, joined with the adjacent, are provided with detachable, for example, bolted joints 12. The extreme end surfaces of the assembled removable skimmers adjacent the restrictive walls 5 have an upper edge in contact with located at an angle to the horizontal plane of the latches 13.

The form works in the following way.

Before starting work, from the set of ducts 8, using detachable joints 12, the cutters of the required length, which correspond to the length of the manufactured products, are assembled, and their slots 9 are installed on the partition walls 7.

When setting up for L-shaped products, the perforators are installed through one partition wall, and if T-shaped products are to be manufactured, the perforators are placed on each baffle, and the two extreme products are either not molded, or made L-shaped. The transversal boards moving by means of a pair of hinged rods 6 along the radius (in the vertical and horizontal planes) press, by means of an inclined latch, the assembled set of sections of cutter formers 8 to the partition walls 7 and the pallet 1.

When the form is dismantled, the hole-cutters 8 move upwards with the products and, conc. / Г

tactics with inclined locks squeeze up and to the side bounding walls 5 with crosshead 4.

After the products are lifted from the mold, the perforators are separated from the products and placed on the baffles 7 for the next molding.

The use of the proposed form allows the product range to be expanded while reducing the amount of airborne equipment required for this.
