The utility model is aimed at ensuring the reliability of the coating with a high service life, which is achieved due to the fact that the prefabricated coating plate includes an upper side 1, two side walls 2, characterized in that a through open groove in section T is made on the lower side 3 of the plate -shaped. 4 ill.

Description

The utility model relates to construction and can be used for prefabricated pavement, pedestrian and garden paths, pedestrian areas and landing areas of public transport, parking lots, streets with low traffic.

The analogue plate for covering roads and other territories is known in the description of the invention to copyright certificate No. 102909, IPC E01C 5/06 of 04/04/1955, publ. 1956, made on a round with a flat working surface and spherical or conical with thinning of the cross section to the center of the supporting surface, the ends of the plates being beveled to the supporting area, the smallest section of the plate in its center reinforced from below by local thickening, the supporting and joining surfaces are corrugated.

Disadvantages: the coating is not reliable enough, the service life is not high enough.

The closest analogue is known to be a prefabricated coating plate in the description of the invention to patent No. 2208080, IPC E01C 5/02, E01C 5/06 from 07/09/2001, publ. 07/10/2003 Bull. No. 19, the contour of which is described by a rectangle, and on two opposite sides there are recesses in the form of isosceles trapeziums, characterized in that the lower part of the plate is made in the form of a rectangle, the contour of which is reduced relative to the central axis parallel to the faces with recesses, by the depth of the trapezoidal recess of the upper parts, and the transition between the corresponding offset lateral faces of the upper and lower parts is carried out using inclined planes.

Disadvantages: the coating is not reliable enough, the service life is not high enough.

Effect: ensuring the reliability of the coating with a high service life.

The technical result in the plate of the prefabricated coating including the upper side, two side walls, is achieved due to the fact that on the lower side of the plate there is a through open groove in the T-section.

Using a trowel, a layer of sand-cement mortar is applied to a concrete base or to a drainage layer of crushed stone and sand and leveled with a trowel-comb. On the mixture of the solution through the open groove in the cross section of the T-shaped stack plate prefabricated.

Concrete mortar enters the grooves of the slabs of the prefabricated coating, due to the shape of the groove, which has many points of adhesion to the concrete mortar, when the mortar dries, a concrete plug is formed in the groove of the slab, ensuring solidity and, as a result, high reliability of the coating with a high service life.

A comparative analysis of the proposed solution with analogues allows us to conclude that the claimed utility model differs from the known analogues by the combination of essential distinguishing features, the utility model meets the conditions of patentability: it is new, industrially applicable.

Comparison of the proposed technical solution with other technical solutions shows that it meets the criterion of significant differences, since the introduction of new features leads to the manifestation of a new property in the device, ensuring the reliability of the coating with a long service life.

The device is illustrated by drawings, where

in FIG. 1 shows a prefab plate;

in FIG. 2 shows a prefabricated cover plate with a through open groove in a T-section;

in FIG. 3 shows a prefabricated cover plate from the end view with a through open groove made in an oval section;

in FIG. 4 shows a prefabricated cover plate from the end view with a through open groove made in the shape of a bowl,

The prefabricated cover plate includes an upper side 1, two side walls 2, characterized in that a through open groove in a T-shaped section is made on the lower side 3 of the plate.

It is possible to design a prefabricated slab with a groove made in an oval section, with a groove made in a bowl shape, with a groove made in a trapezoidal section and with side walls made in the shape of a triangular prism. But the best result in ensuring the reliability of the coating with a high service life is achieved only when a through open groove in a T-shaped section is made on the underside of the plate 3.

The prefabricated coating plate is laid as follows.

Using a trowel, a layer of sand-cement mortar is applied to a concrete base or to a drainage layer of crushed stone and sand and leveled with a trowel-comb. On the mixture of the solution through the open groove in the cross section of the T-shaped stack plate prefabricated.

Concrete mortar enters the grooves of the slabs of the prefabricated coating, due to the shape of the groove, which has many points of adhesion to the concrete mortar, when the mortar dries, a concrete plug is formed in the groove of the slab, ensuring solidity and, as a result, high reliability of the coating with a high service life.

In order for the material to be more closely connected with cement, each tile must be tapped with a rubber hammer. In the process, it is necessary to achieve a minimum size of seams between the elements.

When the slabs are completely laid, wait until the cement-sand mortar is completely dry.

After drying, grout the joints. For this operation, use the same solution as for laying the coating. The mixture is collected in a gun and distributed between each plate. After the solution has dried, excess mixture from the prefabricated plates is removed with a stiff brush.

Prefabricated slabs can be laid in places with high pedestrian traffic or, for example, in parking lots for cars and trucks.
