(54) FORM FOR PRODUCTION OF PRODUCTS WITH RELIEF PATTERN

one

The invention relates to the construction and can be used in the manufacture of molded products from concrete and reinforced concrete.

The known form for the manufacture of plates with a relief pattern, containing a rigid pallet, longitudinal and transverse beads and flexible matrices, on which a layer of material 1 is applied.

This form cannot be used to form reinforced concrete screens for LOD-. and balconies, because the presence of flexible matrices does not allow the creation of a relief of a repeating and permanent pattern, for example, on a batch of screens.

The most similar to the proposed form for the manufacture of products with embossed ris is a hole, including a pallet, longitudinal and transverse sides and a matrix made inlaid from three-dimensional elements with a relief pattern 2.

The disadvantages of this form are the difficulty of preparing volumetric elements, their fragility in production conditions and the low percentage of use of the relief patterns of the composing matrix, since out of six drawings of each volume element one is involved in the work.

The purpose of the invention is to simplify the design and expand the technological capabilities of the form;

This goal is achieved by the fact that in the form for the manufacture of products with a relief pattern, including a pallet, longitudinal and transverse sides, and a matrix made inlaid from volumetric elements with a relief pattern, each volume element is made in the form of a metal tile, the relief pattern of which is square. a field divided by a diagonal, on one side of which there is a smooth surface, and on the other, two trihedral prisms joined by edges, with one of the edges of each prism lozheno on the diagonal of the square; the length of the square of the edges located on the diagonal is equal to the length of the diagonal.

Claims (2)

FIG. 1 shows a general view of the form; in fig. 2 - cross section of the form; in fig. 3. - General view of the volume element of the matrix with a relief pattern; in fig. 4 and 5 show layouts for placing on a pallet bulk elements of a matrix for various options of embossed patterns. On the pallet 1 between the sides 2, three-dimensional elements 3 in the form of aluminum alloy tiles are laid. Each volume element on one side has a relief pattern, which is a square tile field, divided by a diagonal 4, on one side of which there is a smooth surface 5, and on the other side are two trihedral prisms 6. The prisms join each other with the edges 7, and the other edges form diagonal 4. Forms for the manufacture of products with a relief pattern can be steel, reinforced concrete or steel fiber concrete. During molding, the voluminous elements 3 are laid in the tray 1 with the relief pattern upwards, in the sequence indicated in one of the variants of FIG. 4 and 5. Next, a layer of colloidal cement mortar is applied onto the working surface of the mold; spraying to obtain a non-porous product surface. After the reinforcement has been laid, the embedded parts and the concrete mixture are compacted with surface vibrators. Formed in the form of the product, subjected to heat and moisture treatment in the usual ways and served on the stripping. Next, the product is sent to storage, and the form is ready for reforming after cleaning. The economic efficiency of the application of the proposed form for the manufacture of articles with a relief pattern consists in the fact that thanks to the use of a uniform volume element, a set of which forms a matrix for obtaining a relief pattern, it is possible to obtain ten different relief variants on the product only as a result of a certain packing of volume elements on the pallet forms. The variety of the obtained matrix reliefs is achieved due to the construction of the volume element and its design. Such three-dimensional elements are easily obtained by casting from aluminum alloys both in a chill mold and by melted models. Claim of the invention A mold for the manufacture of articles with a relief pattern, including a pallet, longitudinal and transverse beads and a matrix made of a composite element with a relief pattern characterized in that, with the aim of simplifying the design and expanding the technological possibilities, each volume element is designed in the form of a metal tile, the relief pattern of which is. a square field divided by a diagonal, on one side of which the surface is smooth, and on the other side are two trihedral prisms joined by edges, one of the edges of each prism is located on the diagonal of the square, and the length of the edges located on the diagonal of the square is diagonal .
