Abstract

The invention relates to the manufacture of precast concrete and reinforced concrete products and improves the convenience of stripping. This is achieved by the fact that in the form for the manufacture of products from concrete mixtures the contoured forming frame 4 is made in the form of a hinged multilink with a link rotation stop. The free end of one of the extreme links has a horizontal slot 9 for accommodating the other extreme link. 4 il.

FIG. 2

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

The aim of the invention is the convenience of stripping.

FIG. 1 schematically shows a form for the manufacture of products from concrete mixtures, general view, in section; in fig. 2 is a contour forming frame of the form; in FIG. 3 is a fragment of a contour forming frame (hinged connection of links) in FIG. 4 - a fragment of the contour forming frame (connection of the free ends of the links).

The form for the manufacture of products from concrete mixes consists of base beads 1 with supporting pads 2 for placing the pallet 3. The base boards cover a contour shape-forming frame 4, made in the form of a hinged multiplayer with limiter 5 turns of intermediate 6 and extreme 7 and 8 links.

To fix the extreme links in the link 7, there is a horizontal slot 9 in which the projection 10 of the link 8 is placed.

The assembly and disassembly of the mold is carried out at the technological station for the removal of products and the preparation of forms, equipped with jacks 11 and clamps 12 to prevent the form from being vertically displaced during the removal of products.

The sequence of technological operations is as follows.

At the post of removal of products and preparation of molds, base boards 1 are installed, on the supporting platforms 2 of which pallet 3 is laid. Then a mold forming frame 4 is installed and the assembled mold is fed to the subsequent posts of the conveyor, where the molding is carried out and

construction products. Upon completion of the manufacturing operations, the mold is returned to the post of removal of articles and preparation of molds.

For the removal of products, the form is fed under the clamps 12 and installed on the jacks 11, after switching on which the pallet 3 together with the forming frame and the building product (not shown) is moved from the base beads 1. Then the product is released from the forming frame 4 by extending the links in the horizontal plane with any affordable way, such as vacuum grippers. In this case, the separation of the links is regulated by limiters 5. The product is transported to the finished product warehouse, and the shaping frame 4 is returned to its original position and placed on a pallet, with which it is returned to its original position when lowering the jacks.

If necessary, the forming frame 4 is cleaned from adhered concrete at the adjacent conveyor post, and at the dismantling post the forming frame can be replaced.
