RU157786U1 - SPARK-EXPLOSIVE PRODUCTS FROM FINE-CONCRETE CONCRETE WITH DECORATIVE LIGHTING FROM INSIDE - Google Patents

Abstract

Spark-proof product made of fine-grained concrete with decorative illumination inside, made with the possibility of illuminating it from the inside, characterized in that it contains two layers, the first of which, located on the front side of the product, is made of a mixture of fine-grained concrete with light-conducting particles and specific additives for removing electrostatic fields, as well as blocking spark emission, the second layer is made of high-strength concrete, while light sources are placed on the border between the first and second layers but.

Description

The utility model relates to the production of building materials and can be used in the manufacture of plates for wall cladding of civil, military and industrial buildings, as well as in the manufacture of floor, paving, road and airfield slabs, curbs, and other concrete products with a high level of technical safety and decorative properties as a light source, provided by their illumination from the inside.

Known decorative products containing on the surface (front) layer various reflective particles, which when illuminated from the outside provide an enhanced decorative effect. The disadvantage of such products is the loss of decorative properties due to mechanical damage and the possibility of sparks from shock and friction with metal and other objects.

Known decorative tile patent utility model No. 128206, as well as Light Tile (VILLEROY & VOSN), equipped with LED lights mounted flush with the front surface of the tiles in the holes.

And in this case, mechanical damage and sparks are possible, for example when cleaning.

The problem to which the claimed utility model is directed is to expand the functionality of explosion-proof concrete products and can be used in production facilities for the processing of oil and gas substances, runways of airfields, woodworking, flour milling and military production facilities explosive substances, and also their use as technically safe fixtures.

This problem is solved in that an explosion-proof product of fine-grained concrete with decorative illumination from the inside, made with the possibility of illumination from the inside, characterized in that it contains two layers, the first of which, located on the front surface of the product, is made of a mixture of fine-grained concrete with light-conducting particles and specific additives to remove the electrostatic field, as well as blocking the generation of sparks, the second layer is made of a mixture of high-strength concrete, while at the border between the first and second Loi placed light sources.

The presence of two layers provides the possibility of an internal arrangement of light sources. The implementation of the first layer, located on the front surface of the product, from a mixture of fine-grained concrete with spark-explosion-proof additives increases technical safety, and light-conducting particles provide the possibility of the passage of light from inside to outside.

The execution of the second layer only of fine-grained concrete provides high mechanical strength during operation of the product.

Placing spark-preventing additives in the first layer on the front side increases technical safety, and light sources on the border between the first and second layers make it possible to use the product as safe fixtures.

The utility model is illustrated by the drawing: in FIG. 1 shows an explosion-proof decorative product, a general view with a cut.

An intrinsically safe decorative product made of fine-grained concrete made in the form of a regular geometric body (in this case in the form of a tile) with a glossy surface 1 without recesses and holes, contains the first layer 2, made of a mixture of fine-grained concrete with intrinsically safe additives and light-conducting particles. The second layer 3 is made only of concrete with high mechanical strength. At the border between layers 2, and 3, there are light sources 4, - LED or other light sources. Outward from the side part 5, the wires for the electric power source are withdrawn.

As a fine-grained filler, mineral fillers of increased strength (basalt, granite, river sand, etc.) of a fraction from 0 to 3 mm are used. Cement from grade 400 to grade 800 is used as a bonding element. Ground glass, quartz sand, etc. can be used as light-conducting particles.

The following additives are used as special additives to prevent spark release from mechanical stress: aluminum baxite, which fills silicon microcracks, a mixture of chromium oxide and iron oxide to remove the electrostatic field in brittle aggregates such as basalt, silica and siliceous fine-grained particles, as well as two binding additives.

As light sources, LEDs can be used mainly because of their high mechanical strength and reliability. The preferred use of the LED line (the number of light sources in them can be from 1 to 100 pieces), equipped with a common contact group, to which it remains only to connect an electric power source. Such a system can be made up of LEDs of one or different colors, which allows using the only module to get the widest range of light colors (in the case of control using a special controller).

The manufacturing process of concrete products is as follows. On the vibrating table is fixed a form with the underlying bottom for the formation of any textured surface. In two containers, different mixtures of fine-grained concrete are prepared: in the first with special spark-explosion-proof additives and light-conducting particles, and in the second container, a concrete mixture with increased mechanical strength. The products are molded with the vibrator switched on in layers: first, mix with special spark-proof additives and light-conducting particles, then mix fine-grained concrete with increased mechanical strength. During molding, after the first layer is laid, light sources are laid on it according to the specified layout . After completion of the molding process, the vibrator is stopped. In the molding process, it is preferable to use * GRISHINA VIBRATOR * (utility model patent No. 134848), the design of which provides high-quality compaction of concrete mixtures, in the absence of resonant-negative vibrations during the compaction of concrete mixture.

Use the product of fine concrete as follows.

Depending on the conditions of use of the product (for internal or external cladding of wall surfaces) or floor coverings.

This product, after appropriate surface preparation, is laid in accordance with the required technology.

After completion of installation and fixing of spark-explosion-proof decorative lamps, installation of electrical fittings is carried out.

The inclusion of light sources gives the decorative product the effect of an internal glow scattered throughout the volume of this product.
