FIELD OF THE INVENTION The invention relates to an anchor element for the production of a molded facade, which includes a lower part for fastening in a substructure. The invention further relates to the molded facade attached to the substructure, the lower parts of the anchor parts being fastened in the prescribed grid in the substructure and the vapor barrier being attached to the substructure. The invention also relates to the type of production of the molded facade, in which the penetration layer is applied to the substructure and the vapor barrier is attached.

BACKGROUND OF THE INVENTION Facades of modern buildings have to perform numerous functions. You have to protect the building construction from the weather, ensure thermal comfort within the building and last but not least, you should enable the architects to realize an original exterior design of the building.

Modern materials and technologies made it possible to realize facades that may even seem shocking to the generations who grew up in the area of uniform and gray prefabricated housing developments, regardless of these experimental facades are fully functional from the point of view of technical requirements.

An example of such an unusual facade is the so-called "padded" facade, which was realized during the modernization of the cultural center in the French city of Tours. The thermal insulation was attached to the substructure with a vapor barrier, in which round openings were cut out in a regular grid, so that circular depressions with a diameter of 65 cm were created in the thermal insulation, then an elastic plastic hydro insulation film was covered over the thermal insulation, which was then coated In the middle of all the circular recesses mentioned, an anchor point was used to attract the thermal insulation, so that the facade gives the impression of upholstered furniture in which the upholstery buttons embedded in the surface are arranged in a regular grid.

However, this known facade is relatively flat and very "wrinkled", so that the resulting impression is not optimal.

The aim of the invention is therefore to design a solution that would make it possible to produce a fully functional soft facade that has the appearance of upholstered furniture on which upholstery buttons are distributed in a regular grid. This facade is referred to in the application as a molded facade.

PRINCIPLE OF THE INVENTION The stated aim is achieved with the anchor element for the production of a molded facade, which includes a lower part for fastening in a substructure, according to the invention, the principle of which is based on the fact that a spacer tube is fastened to the lower part and is attached to the outside End is provided with a thread for interchangeable connection of an auxiliary mandrel or an anchor screw.

The anchor element according to the invention makes it possible to produce a molded facade that gives the impression of upholstered furniture.

The stated objective is also achieved by the form facade arranged on the substructure, wherein in the substructure in the prescribed grid lower parts of the anchor elements are attached and on the substructure the vapor barrier is attached, according to the invention, the principle of which is based on the fact that from the Subdivide the spacer tubes and stick out at least one layer of thermal insulation on the vapor barrier

AT 16 626 U1 2020-03-15 Austrian patent office is attached, which is covered on the outside with hydro insulation film, the thickness of the thermal insulation when not compressed is greater than the length of the spacer tubes. In the area of the anchor elements, the hydro insulation film is tightened together with the thermal insulation using the anchor screws screwed into the spacer tubes at the ends of the spacer tubes.

The molded facade according to the invention is not only fully functional, but also allows to realize original constructions.

According to the advantageous embodiment, the molded facade under the head of each anchor screw is provided with a washer with a layer of heat-activatable adhesive which bears against the back of the hydro insulation film and the head of each anchor screw is covered with a welded cap made of homogeneous film.

According to a further advantageous embodiment of the molded facade, the thermal insulation includes at least two layers, the first layer, which is closer to the substructure, with thermal insulation panels with a density of 70 to 150 kg / m ³ and the second layer with softer thermal insulation panels the density number is 25 to 45 kg / m ³ .

The mentioned goal is also achieved by the method in the manufacture of the molded facade, in which a penetration layer is applied to the substructure and the vapor barrier is applied, according to the invention, the principle of which is based on the fact that the substructure is then prescribed in advance the lower parts of the anchor elements are fixed at regular intervals, from each of which a spacer tube protrudes.

Auxiliary mandrels are screwed into the spacer tubes of the anchor elements. Of course, the auxiliary mandrels can be screwed into the spacer tubes at any time in advance.

Then at least one layer of thermal insulation is glued to the substructure in such a way that the thermal insulation is opened onto the spacer tubes and onto the auxiliary mandrels of the anchor elements which protrude from them, the total thickness of the thermal insulation being greater than the length of the spacer tubes.

Thereafter, webs of the hydro insulation film are hung from the thermal insulation from above so that the webs of the hydro insulation film overlap on the sides.

On each auxiliary mandrel, a metal disc is pushed from the side under the hydro insulation film, on which, on the side facing the back of the hydro insulation film, a layer of heat-activated adhesive is applied.

The washer is heated by induction heating to the predetermined temperature, whereby the adhesive layer is activated and the washer with the activated adhesive is attracted by means of a magnet to the back of the hydro insulation film, with which the washer is thus firmly glued.

Then the magnet is removed and the auxiliary mandrel is unscrewed.

Then the anchor bolts are partially screwed into all spacer tubes of the anchor elements, which are gradually tightened and at the same time the hydro insulation strips are gradually welded to the sides, the recessed depth of the anchor bolts of the anchor elements in the thermal insulation being given by the length of the spacer tubes of the anchor elements .

After tightening the anchor bolts, caps made of homogeneous film are welded onto their heads.

In the manner according to the invention, a complicated shaped facade can be produced without the outer hydro insulation film being damaged during assembly.

According to the advantageous method, the thermal insulation is composed of two layers, with the first layer of heat first on the substructure

EXEMPLARY EMBODIMENTS The embodiment of the anchor element 5 according to FIG. 1 for producing a molded facade includes a lower part 6 for fastening in a substructure 1. The set screw of the lower part 6 is screwed into the internal thread of the stainless steel spacer tube 7, which has an internal thread at the other end for the interchangeable connection of an auxiliary mandrel 8 or an anchor screw 10. An interchangeable connection is understood to mean that during assembly the auxiliary mandrel 8 is first screwed into the spacer tube 7 and in the next phase of assembly the auxiliary mandrel 8 is unscrewed and the final anchor screw 10 is screwed in its place.

An example of the design of the molded facade is shown as a section on Fig. 4 and the external view of the building with such a facade is shown in Fig. 5.

The molded facade is attached to a substructure 1, which can form any known constructions made of concrete, masonry, wood and other constructions, both vertical and horizontal.

On the substructure 1, a known penetration layer is applied and on this a vapor barrier 2 is attached, for example bitumen sheets, polyethylene foils, polypropylene foils, various types of foil with an aluminum layer, which increase the impermeability to water vapor, u. Ä.

In the substructure 1, lower parts 6 of the anchor elements 5 are fastened in the prescribed grid, and spacer tubes 7 protrude from the lower parts 6.

On the vapor barrier 2, a layer of thermal insulation 3 is attached, the mineral wool for facades in the thickness of 80 mm and with the density 70 to 150 kg / m ³ forms. The second layer of the softer thermal insulation 3 is applied to this layer, which forms mineral wool for facades with a thickness of 120 mm and a density of 25 to 45 kg / m ³ . It is obvious to a person skilled in the art that any known thermal insulation 3 can be used which has the properties mentioned.

The thermal insulation 3 is covered on the outside with hydro insulation film 4, which forms a soft PVC film with a thickness of 1.5 mm, stiffened with a PES insert. Other known hydro insulation foils can also be used.

The thickness of the thermal insulation 3 is greater in the uncompressed state than the length of the spacer tubes 7 and in the area of the anchor elements 5, the hydro insulation film 4 together with the thermal insulation 3 using the anchor screws 10 screwed into the spacer tubes 7, at the ends of the Spacer tube 7 tightened.

AT 16 626 U1 2020-03-15 Austrian Patent Office. Fig. 3 shows that under the head of each anchor screw 10 on the back of the hydro insulation film 4 there is a washer 9 with a layer of heat-activated adhesive and that the head of each anchor screw 10 is covered with a welded cap 11 from a homogeneous film.

[0038] The manufacturing process of the molded facade includes the following steps.

A penetration layer is applied to the substructure 1 and a vapor barrier is attached 2. In the example described, the vapor barrier 2 forms the bitumen sheets melted onto the penetrated concrete monolith of the substructure 1.

Subsequently, the lower parts 6 of the anchor elements 5, from which the stainless steel spacer tubes are attached, are attached to the substructure 1 in the previously prescribed regular grid, in this case quadrangles with the dimensions of the sides 100 cm, placed on the top 7 stick out.

In the spacer tube 7 of the anchor elements 5 auxiliary mandrels 8 are screwed, which temporarily blend the thread in the spacer tube 7, so that no particles of mineral wool of the thermal insulation 3 can penetrate during assembly.

Subsequently, the first layer of thermal insulation 3 made of insulation boards with a density of 70 to 150 kg / m ^{3 is} bonded onto the substructure 1 with the aid of a PU adhesive, and then the second layer of the insulation boards is applied to this first layer with the aid of a PU adhesive glued with the density number 25 to 45 kg / m ³ . The thermal insulation panels 3 are opened onto the spacer tubes 7 and onto the auxiliary mandrels 8 of the anchor elements 5 protruding from them, the total thickness of the thermal insulation 3 being greater than the length of the spacer tubes 7, but the ends of the auxiliary mandrels 8 protruding from the thermal insulation 3 (see Fig . 2).

Subsequently, over the thermal insulation 3 webs of the hydro insulation film 4 from a soft PVC film in the thickness 1.5 mm, stiffened with a PES insert, hung. The webs of the hydro insulation film 4 must overlap on the sides so that they can be welded later.

On each auxiliary mandrel 8, a metal disc 9 is pushed from the side under the hydro insulation film 4, on which, on the side facing the back of the hydro insulation film 4, a layer of hot glue is applied (see FIG. 2).

Each washer 9 is gradually heated to the predetermined temperature by induction heating, whereby the adhesive layer is activated, and the washer 9 with the activated adhesive using the magnet, not shown, to the back of the hydro insulation film 4, with which the washer 9 is thus fixed is glued, is used.

Subsequently, the magnet is removed and the auxiliary mandrel 8 is unscrewed.

Subsequently, in all spacer tubes 7 of the anchor elements 5, the anchor bolts 10 are partially screwed in, which are gradually tightened and, at the same time, the hydro insulation strips 4 are gradually welded, the recessed depth of the anchor bolts 10 of the anchor elements 5 in the thermal insulation by the length the spacer tube 7 of the anchor elements 5 is given. The anchor bolts 10 can be pressed into the thermal insulation 3 approx. 10 cm (see Fig. 3). If they are pressed in more, there is a risk that the hydro insulation film 4 will tear. Outside the anchor bolts 10, the thermal insulation 3 retains the original thickness and holds the hydro insulation film 4 in the tensioned state, so that the facade gives the impression of upholstered furniture, the heads of the anchor bolts 10 giving the impression of upholstery buttons (see Fig. 5).

After tightening the anchor bolts 10 caps 11 are welded onto their heads from homogeneous film and thus the assembly of the facade is completed.
