Description

The invention relates to devices for the manufacture of building decorative blocks, slabs, mainly cement-sand, concrete.

Known split form, consisting of a pallet, side walls, fasteners [1].

Also known is a detachable form containing a pallet, walls, clamping screws [2].

Known forms do not allow to obtain multi-colored convex or concave sections of the surface of the product.

The objective of the invention is to expand the functionality of the form.

The technical result is achieved in that the detachable form containing the pallet, walls, clamping screws is provided with at least one element made in the form of a longitudinally dissected body of revolution, and the wall has a channel for installing the element with the possibility of its rotation through 180 °. The element is hollow. The element is made continuous, and its surface has a relief over the cross section.

Figure 1 shows a detachable form; figure 2 shows a part of the wall of the form without an element, a top view; figure 3 shows a cross section of the wall and the hollow element along aa in figure 1; figure 4 is the same as in figure 3 when the element is rotated 180 °; in Fig.5 - the same as in Fig.3 when the element is solid; in Fig.6 is the same as in Fig.3 when performing an element continuous with a relief along a longitudinal section; 7 shows embodiments of an element; on Fig presents the mechanism of rotation of the element.

The mold contains a pallet 1, walls 2, clamping screws 3 for fastening the walls with a pallet. The mold is provided with at least one element 4, made in the form of a longitudinally dissected body of revolution, and the wall has a channel 5 for mounting the element with the possibility of its rotation by 180 ° with the formation between the element and the cavity channel 6. The element is installed vertically (horizontal position of the element on the wall or pallet is an equivalent technical solution) and is removable. In the upper part of the wall there is a one-piece (fig. 1 and 2) or detachable (fig. 7) shell 7 for placing a tubular (across a circular cross-section) part 8 of the element above the shell on the tubular part of the element, a lever 9 of its rotation is fixed, at the bottom of the wall an annular groove 10 is made in the pallet 10. The part of the element located below the shell can be hollow (Figs. 1, 3, 7) or solid (Fig. 5), including a relief (Fig. 6) of a longitudinally dissected body of revolution. In the presence of several elements, the detachable shape may have a mechanism 11 for their rotation, for example, in the form of gears 12 and a gear rack 13.

To feed the decorating cement-sand or concrete (color) mixture into the cavity formed by the channel and the element, a funnel 14, a solution pipe or other device (not shown) can be used. To control the number of mixtures in the mold, a filling line 15 is applied to the wall.

From the pallet 1, the walls 2 by means of clamping screws 3 collect the form. The element 4, made in the form of a longitudinally dissected body of revolution, is installed in the channel 5. In this case, the tubular part 8 of the element is held by the shell 7, and the part of the element located below the shell, which is in the form of a hollow or solid, including with a relief, longitudinally dissected body of revolution , is installed at its end in the annular groove 10.

Before use, the mold is lubricated (machine oil or petroleum jelly). Then the form is filled to line 15 with a mixture, for example, concrete. At the same time, a decorating color mixture or several color mixtures is fed through a funnel 14 into the cavity 6 formed by the channel and the element. The mixture is compacted, for example, using a vibrating table. Then the element is rotated 180 °. To rotate the element, a lever 9 or a rotation mechanism 11 in the form of gears 12 and a gear rack 13 is used. In this case, the decorating mixture filling the element occupies the shape of the space formed by the body of revolution. After hardening of the mixtures, the form is taken apart, the finished product is removed.

Using the proposed form, it is possible to obtain products with protruding above the surface (Figs. 1 and 7) or embedded in the surface (Figs. 5 and 6) of sections of a colored (multicolor) ornament. In this case, each element requires filling with a decorating mixture.

The form also allows you to get on the surface of the product convex (figure 4) and concave (figure 3) areas with a single-color ornament. In this case, the element is not filled with the decorating solution.

Thus, when using elements filled and unfilled with a decorating mixture, it is possible to obtain both convex and concave, both single-color and multi-color ornaments, on the surface of the product.
