Abstract

The invention relates to the manufacture of precast concrete and reinforced concrete products and provides for the convenience of dismantling products with multi-tiered reinforcement releases. This goal is achieved by the fact that the form for the manufacture of products from concrete mixes with extras is provided with guides 1 1 and covered with their sliders 10 fixed respectively on pallet 1 and lower combs 3. The latter are made movable in a direction perpendicular to reinforcing bars, and on their side faces x7, grooves 8 are formed for fittings 9. 2 sludge,

FIG. one

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

The purpose of the invention is the convenience of dismantling products Q by a multi-tiered arrangement of reinforcement heads,

FIG. Figure 1 shows schematically the proposed form for the manufacture of products from concrete mixtures with outlets of reinforcement, a section; on; FIG. 2 is a section A-A in FIG. 1.

The form for the manufacture of products from concrete mixes with releases of reinforcement consists of a pallet 1 and composite I boards in the form of two combs 2 and 3 installed one on another, which are interconnected with retainers in the form of supporting posts 4 and wedges 5 located in grooves 6 racks 4. Combs 2 and 3 are made with trapezoidal in the longitudinal section of the protrusions and depressions. One of the sides of adjacent trapezoidal protrusions and depressions of the combs 2 and 3 is made perpendicular to the pallet 1, and on the vertical faces 7 of the combs 3 grooves 8 are formed to release the armature 9. To the comb 3 there are slides 10 contacting with guides 11 fixed perpendicularly to the reinforcing bars m on the pallet. The projections of the upper comb 2 contact with their faces with the corresponding slots of the lower ridge 3.

The form for the manufacture of products from concrete mixtures with fittings works as follows.

Lower comb 3 by means of a screw or eccentric mechanism (not shown) is shifted according to the line

right to the left. A reinforcement cage with outlets 9 is installed on the prepared pallet 1, then the comb 3 is shifted perpendicular to the releases until the latter enter the grooves on the vertical faces 7 of the comb 3. Then the top comb 2 is directed onto the supporting posts 4 and fixed with a wedge 5. After that, the assembled form is filled with concrete mixture and processed according to a given technology.

For stripping the mold and removing the finished product from it, the wedge 5 is removed from the support posts 4, then the upper comb 2 is removed, the lower comb 3 is shifted along the guides 11 away from the outlets 8 until they completely exit from the grooves to the gran x 7 and the product is removed from the form.

Claims (1)

Invention Formula A form for the manufacture of products from concrete mixes with releases of reinforcement, containing a pallet and composite boards from one-sided combs with trapezoidal in cross section protrusions and depressions, with grooves formed in them for releasing reinforcement, with the aim of convenience of stripping products with multi-arrangement of reinforcement releases, it is equipped with guides and sliders covering them, fixed respectively on the pallet and lower combs, made movable in the direction Dikulja polar reinforcing rods and grooves for passage of rebar, are formed on the lower faces of the combs.
