Description

The invention relates to devices for the manufacture of building products: blocks, slabs, mainly cement-sand, concrete, gypsum, ceramic.

Known split form consisting of a pallet, walls, clamping screws [1]. This form does not allow to obtain products with a textured surface.

Also known is a detachable form containing a pallet, walls, fasteners [2]. To create a relief on the surface of products, a relief-forming material (gravel, crushed stone, rods, ropes, frames, etc.) is first placed on a pallet of this form, and then a synthetic film is pulled from above, which creates certain inconveniences and reduces labor productivity.

The objective of the invention is to obtain a textured surface of the products while ensuring the convenience of the form in operation.

The technical result is achieved by the fact that a detachable mold for the manufacture of building products containing a pallet, walls, fasteners, is additionally equipped with a removable elastic pocket for accommodating a relief-forming material, suspended on a bar freely passing through the loops, with the possibility of turning it into the mold volume. The pocket is divided into sections.

Figure 1 shows a detachable form for the manufacture of building products; figure 2 shows a pocket divided into sections; figure 3 is the same as in figure 2, a section along aa.

The mold contains a pallet 1, walls 2, fastening elements 3. The mold is equipped with a removable elastic pocket 4 for accommodating relief-forming material. The pocket can be made of synthetic film, fabric, nylon sieve. The pocket is suspended on a bar 5, freely passing through loops 6, with the possibility of turning it over into the volume of the mold. The pocket can be divided into sections 7.

From the pallet 1, the walls 2 by means of fasteners 3 collect the form. A bar 5 is inserted into the loops 6 with a pocket 4 put on it. The pocket or its sections 7 are preliminarily filled with a relief-forming material and turned into a mold volume. The shape and surface of the pocket is lubricated (machine oil or petroleum jelly). After that, the mold is filled, for example, with a cement-sand mixture, which is compacted and left to solidify. After the mixture has hardened, the mold is taken apart, the finished product is removed with a relief surface.

The form is convenient in operation, it allows you to get a variety of products with a textured surface.
