Description

 The technical field to which the utility model relates.

The utility model relates to construction and can be used in the construction of roofing of roofs of industrial and public buildings and structures.

 State of the art

The metal roof is known from the prior art (see [1] RF patent for utility model No. 95708, IPC E04D 11/02, published July 10, 2010), consisting of an upper and lower profiled floor mainly with trapezoidal corrugations, thermal insulation, anti-condensation film and support elements discretely installed along the roof run and connected to it through the lower profiled flooring, located with the formation of a ventilated space under the upper profiled flooring. The top profiled flooring can be made with a polymer coating. Thermal insulation is laid on the lower profiled flooring, mainly from light heat-insulating material, for example, in the form of plates made of polyurethane foam or expanded polystyrene. The upper profiled flooring rests on a metal crate, consisting of upper and lower elements connected to each other, between which an anti-condensation film is placed.

Also known from the prior art is a roofing building panel (see [2] RF patent for utility model No. 148121, IPC E04D 11/00, publ. 11/27/2014), consisting of arranged in order: internal profiled metal sheet, heat-insulating layer, additional metal sheet, waterproofing layer, all layers are bonded to each other with special glue or through self-tapping screws.

The disadvantages of these analogues are the high cost of the roof (two metal sheets, the need for ventilation, since the metal is subject to corrosion), heavy weight (two sheets), the need to fasten the layers with special glue or self-tapping screws, the inability to give the product a classic look of piece tiles. Thus, all of the above roofing is molded material, and not piece tiles.

The closest analogue in terms of essential features is a roof covering (see [3] RF patent for utility model No. 14595, IPC E04D5 / 00, publ. 10.08.2000), containing successively laid on the base: vapor barrier layer, thermal insulation layer made of foam based on polyurethane foam, a roofing carpet, the coating additionally containing a layer made of a flat asbestos-cement sheet and located between the thermal insulation layer and the roofing carpet. The base is made, for example, of profiled flooring or reinforced concrete slabs. The asbestos-cement sheet is made with sprue through holes through which the injection of liquid polyurethane foam is carried out into the interlayer space between the layers of thermal insulation and the asbestos-cement sheet, which cures and provides a strong connection of the layers. The roofing carpet is glued to the asbestos sheet.

The disadvantages of the prototype are: the use of a flat asbestos-cement sheet, harmful to the health of the material, having high fragility and a sufficiently large weight. The use of a flat sheet does not allow to give the shape of a classic tile, while the sheet is molded, which implies special requirements for transportation, loading and lifting on the roof. The material is not a piece of tile, but a sheet multilayer coating.

Utility Model Disclosure

The objective of the claimed utility model is to create a roofing that allows you to protect the attic rooms from heating in the summer and cooling in the winter, in private pitched house-building, while maintaining the classic form.

The technical result of the claimed utility model is to increase the insulating and sound insulating properties.

The technical result is achieved due to the fact that the roof tile contains a lower protective layer made of polyethylene terephthalate with a metallized base, a technical layer made of high pressure polyethylene, a cardboard layer, a heat and sound insulation layer made of polyurethane foam, and an upper protective layer made of from polyethylene terephthalate.

Also, the technical result is achieved through the use of aluminum as a metallized base.

Also, the technical result is achieved due to the fact that the upper protective layer is painted over the entire thickness of the layer with modified UV stabilizers and flame retardants.

Brief Description of the Drawings

Figure 1 shows a section of a piece of multi-layer roofing tiles.

In the drawing, the numbers indicate the following positions:

1 - metallized base;

2 - lower protective layer made of polyethylene terephthalate;

3 - technical layer made of high pressure polyethylene;

4 - a layer of cardboard;

5 - heat and sound insulating inner layer made of polyurethane foam;

6 - upper protective layer made of polyethylene terephthalate.

Utility Model Implementation

The roofing tile contains a lower protective layer (2) made of polyethylene terephthalate with a metallized base (1) made of aluminum. The lower protective layer (2), which is also a substrate for metallization, protects against mechanical damage, and the metallized base (1) applied to it reflects infrared radiation back inside the house (room).

On the lower protective layer there is a technical layer (3) made of high pressure polyethylene, on top of which there is a cardboard layer (4). On the cardboard layer (4) there is a heat and sound insulating inner layer (5) made of polyurethane foam. The cardboard layer (4) absorbs two-component polyurethane foam, thereby increasing adhesion to the high pressure polyethylene layer (3), which in turn glues the cardboard and the lower protective layer (2).

On top of the heat and sound insulating inner layer (5) is the upper protective layer (6) of polyethylene terephthalate, painted over the entire thickness of the layer with modified UV stabilizers and flame retardants. The weight of the upper protective layer (6) is several times lower than the weight of the metal sheet or asbestos-cement sheet (used in analogues). At the same time, layer (6) is resistant to corrosion, mold and fungus do not start on it, it protects from external mechanical influences and from the action of ultraviolet radiation, thereby increasing thermal and sound insulation properties. In this case, the protective layer of polyethylene terephthalate allows you to give the roofing a classic look of piece roofing material - tiles.

A non-hygroscopic thermal insulation material polyurethane foam in the form of a heat and sound insulation layer (5), at the time of foaming and polymerization, has strong adhesive properties, thus connecting (gluing) the upper (6) and lower (2) protective layers of polyethylene terephthalate, including due to application of a technical layer (3) and a cardboard layer (4).

The polymerized polyurethane foam, which fills the entire internal volume of the product, gives rigidity to the resulting structure, which allows the roofing to withstand increased loads (for example, when walking on the roof).

The inner layer (5) of two-component polyurethane foam gives the product low heat conductivity, high noise absorption, and also, filling the entire internal volume of the product, gives it rigidity.
