Description

one

The invention relates to steel formwork for precast concrete and can be used in the building materials industry and other industrial fields related to the molding of reinforced concrete products.

The known form for the manufacture of construction products from cellular concretes, including a pallet on which the face and longitudinal sides are mounted, and to increase the reliability of fixing the pallet during heading, the pallet is made with a sacrum mounted bushings on the ends, from which the hinged lever is connected to the vertical mounting resistant ij.

Also known is the form for the manufacture and subsequent heating, processing in packages of concrete products, including the box-section pallet with the lower plane corresponding to the shape of the surface of the product and the bead, with the perimeter pallet made with grooves to accommodate protruding above the surface of the product below the underlying forms 2.

Closest to the present invention is a form for the manufacture of concrete products, including a pallet, hinged beads and brackets fixed on the pallet with grooves 3,

Known technical solutions are not. provide the ability to transport stacked forms, so

10 as they do not provide for the interaction of the slinging devices of the forms between the assembly and the uniform distribution of the loads of the weight of the overlying forms on the slinging devices

15 each.

The purpose of the invention is to increase the productivity of manufacturing products due to the implementation of package transfer of porting forms.

This goal is achieved by the fact that in the form for the manufacture of reinforced concrete products, including a pallet, hinged beads and brackets mounted on a floor with grooves, the latter are made with bevels protruding behind the pallet, and the beads are provided with bearing pads and wedge guide plates interacting with slots brackets.

FIG. 1 shows the form, the general plan in FIG. 2 is a view A in FIG. in FIG. 3, view B in FIG. ; in fig. 4 shows a section B-B in FIG. If. 5 is a view of FIG. four.

The form contains the pallet 1 and the beads 2, which are hingedly connected to the pallet by means of loops 3 and fixed by locks 4. On the pallet 1 brackets 5 are fixed, which are made with bevels 6 protruding beyond the pallet 1 to limit the movement of the forms in the transverse plane and the lifting holes 7. forms. The slots 8 are formed between the brackets 5. The beads 2 are provided with wedge guide plates 9 to restrict the movement of the mold in the longitudinal plane, since they can fit into the grooves 8 of the brackets 5 when the molds are placed in the stack, and with the stops 10 for engaging with the pallet brackets 5 1 through pads 11 and lintels 12. MedUn with brackets 5 stiffening ribs 13 are installed. The stacked forms can be lifted and transported by grippers 14 which engage with jumpers 12 or hooks (not shown) behind holes 7 of brackets 5.

The stacking of the forms in a stack one upon another and their simultaneous lifting and transporting into the curing chamber for hardening the concrete is carried out as follows.

Several forms are placed on the lower form in the stack, with the wedge guide pads 9 of the beads 2 of the lower form being inserted into the grooves 8 of the upper form formed between the brackets 5 of the pallet 1 and 1 of the lower beads Forg-i, excluding the movement of forms both in the transverse and longitudinal planes, and then all the forms laid on each other in the stack are lifted and transported either by the grippers 14 engaged

with jumpers 12 of the bottom shape tray 1, or with hooks engaged with the holes 7 of the bottom holes 5 of the bottom shape of the tray 1.

After the concrete has hardened, all forms are simultaneously lifted and transported from the steaming chamber above as indicated.

The execution of the pallet brackets with bevels, and the boards with linings and stops allows the lifting and transport of the forms in the foot with a uniform distribution of loads from the weight of the overlying forms on the slinging devices, each.

According to the indicative data, the manufacture of products in forms made in this way can be increased depending on the time required by the technological process for finding products in the steaming chamber and the number of forms in the foot, approximately n & 50-200%.
