Description

The proposed utility model relates to decorative products, namely to surface coatings.

Closest to the proposed utility model is a facing plate, RF patent No. 2196052, B44C 5/04, containing particles of crushed stone-like materials fixed to the substrate by means of a binder. The substrate is made of pressed sheet material. Stone-like materials have a particle size of 1 to 10 mm and are mounted on a substrate with the possibility of forming a continuous front layer by means of a binder. The binder is applied in an amount of 0.6 ÷ 1.1 kg / m ² , forming an adhesive layer.

This solution is not technologically advanced for surfaces of complex spatial and curvilinear shape, because To cover them, it is first necessary to make a substrate of an appropriate shape, and only then cover it with particles. In the presence of protrusions and depressions, the laying of the substrate can be difficult.

The technical problem to which the proposed utility model is directed is the possibility of covering both rectilinear, horizontal and vertical surfaces and surfaces of complex spatial shapes, curved, with protrusions and depressions, etc., as well as reducing the number of voids.

The problem is solved due to the fact that in a decorative coating consisting of individual elements forming the front layer and fixed by means of a binder, the elements have a shape close to the shape of a triangle, the sides of which are convex and the corners are rounded, and the following condition is met:

where R is the radius of curvature of the sides;

r is the radius of rounding of the corners,

while the elements are made similar and have at least two types of sizes.

Figure 1 shows a decorative coating; figure 2 is a separate element; figure 3 - similar elements (similarity coefficient 0.7); figure 4 - similar elements (similarity coefficient 0.5); figure 3 - similar elements (similarity coefficient 0.3).

The decorative coating consists of individual elements 1 - tiles, which, in general, have a three-dimensional shape, similar to a triangle, but having a thickness. The upper surface of the element 1 may be flat, as well as convex or concave.

Elements 1 have sides 2 made convex with a radius of curvature R.

Sides 2 intersect at angles 3 that are rounded with radius r.

Elements 1 are made in the following ratio:

where R is the radius of curvature of the sides 2;

r is the radius of the fillet 3.

When you exit this ratio of sides 2 and angles 3, element 1 degenerates into either a circle or a triangle, which does not provide the specified technical result.

In this case, the optimal ratio is:

The decorative coating has at least two types-sizes of elements 1. In this case, the elements 1 will be similar, the similarity coefficient can be:

k = (0.1 ÷ 0.9)

where k is the similarity coefficient.

The choice of similarity coefficient depends on the type of surface to be coated.

If necessary, any number of types-sizes of elements 1 can be used.

Elements 1 can be made of various materials, for example, ceramics, glass, etc.

The upper surface of the elements 1 may be colored.

Making a decorative coating of surfaces is as follows.

For applying a decorative coating, the surface (not shown in Fig.) Is properly prepared, cleaned, degreased, etc.

Then a binder is applied (not shown in FIG.), For example, tile adhesive.

Then the elements are stacked 1. The stacking of the elements 1 can occur in any order, and you can also combine different types and sizes to form a picture.

The use of this decorative coating allows you to design any surface as rectilinear, horizontal and vertical, and curved, as well as with protrusions, troughs, etc.

The use of various types and sizes of elements 1 allows you to decorate surfaces of any size, while avoiding cutting elements 1 to completely fill these surfaces.

The possibility of using elements of 1 different color extends technological capabilities, allowing you to create mosaic-like surfaces ..
