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

The well-known multi-site form for the manufacture of products from concrete mixtures, comprising a pallet, hinged-on its longitudinal and transverse sides and removable partition walls 1.

The disadvantage of this form is the use in it of removable partitions, extracted by means of lifting means, which causes a great deal of labor during demolishing and the difficulty of using the form in conveyor production.

Closest to the present invention is a multi-part form for the manufacture of products from concrete mixes, containing outer and inner boards installed on the pallet, the latter of which are connected by means of a stripping tool with one of the outer boards 2.

The disadvantage of this form is the limited stroke of the outer outer and, accordingly, inner sides, which does not allow to manufacture products with a complex configuration of ends.

The purpose of the invention is to enable the manufacture of products of complex configuration.

This goal is achieved by the fact that in the multiplace form for the manufacture of products from concrete mixtures containing outer and inner boards installed on the pallet, the latter of which are connected by means of a stripping tool with one of the outer boards, the inner boards are made folding, the stripping tool is made in two connected hydraulic cylinders, one of which is pivotally mounted on a pallet and is connected to the outer rail, and the other is pivotally connected to the inner rims.

FIG. 1 shows schematically a form, a plan view; in fig. 2 - principle hydraulic circuit; in fig. 3 shows section A-A in FIG. one; in fig. 4 shows a section BB in FIG. one..

The multi-sided form contains a pallet 1, transverse outer sides 2, short 3 and long 4 longitudinal outer sides and inner sides 5. All sides are hingedly connected to the pallet 1.

The longitudinal and transverse outer boards have pivot arms 6, which, when influenced, open the sides.

On the pallet 1 is installed a hydraulic cylinder 7, the brush of which 8 is pivotally connected to the longitudinal outer side 4.

Under the mirror of the pallet mounted hydraulic cylinder 9, the body of which and the brush 10 is pivotally attached to the cantilever arms II, attached to the inner sides 5.

The fluid from the hydraulic cylinder 7 to the hydraulic cylinder 9 and pumped back through the flexible hoses 12. The hydraulic cylinder 7 is closed by a casing 13.

The form works as follows.

The beads 3 are placed in a working position by the action of their own weight immediately after removing the products from the mold.

Pressing the pivoting levers 6 close the transverse beads 2 and the longitudinal bead 4. In this case, the longitudinal bead 4 pushes the rod 8 of the hydraulic cylinder-pump 7. The fluid from the piston cavity of the pump 7 through flexible hoses 12 is pumped into the rod cavity of the hydraulic cylinder of the executive 9. The hydraulic cylinder body 9 and The rod 10 moves and, through the hinge joints, rotates the cantilever levers 11 and the inner beads 5 connected to them, setting them in the working position. At the same time, the fluid from the piston cavity of the cylindrical cylinder 9 is pumped into the rod of the hydraulic cylinder 7.

All sides in the working position are locked with locks (not shown). The form is prepared for the molding of reinforced concrete products.

When removing the product, the locks are released, using the pivoting levers 6 to open the longitudinal 4 and lateral beads 2. When the longitudinal bead 4 is opened, it moves the rod 8 of the hydraulic cylinder 7, and the liquid from the hydraulic cavity of the cylinder 7 is pumped into the piston cavity of the hydraulic cylinder 9. The liquid moves the hydraulic cylinder body 9 and the rod 10, which through the cantilever levers 11 reveal the inner side 5. The form is open.

The use of the proposed form in the industry of precast concrete and reinforced concrete reduces the labor intensity of manufacturing products of complex configuration.
