TECHNICAL FIELD

The non- invasive fixing device for fixing of building insulation to a structural or decorative component of mechanically fixed cladding, according to the invention, is applicable in the field of construction; for example, during the erection of insulated ventilated facades or interior constructions.

BACKGROUND ART

Considering the condition of the equipment, we are aware of a fixing method for outer insulation to a building during erection of ventilated facades, during which the insulation is fixed to the basic construction (the building wall) with the help of special dowels.

The process includes the following operations:

- pre-fastening of the insulation to the wall;

- final fastening of the insulation that includes:

• drilling holes in the insulation and the wall, which represents invasion of the wall;

• placing the dowel in the hole;

• fixing the dowel with a clamping nail.

The so-called insulation fixing is applied to other elements of building construction, aside from ventilated facades. All of them contain a number of disadvantages, which are:

- wall invasion - compromising the basic construction, which is particularly undesirable when placing insulation on old buildings, because it creates a risk of compromising their strength; - low productivity during insulation fixing due to the need for drilling dowel installation holes for fixing of insulation;

- different levels of productivity during the process of drilling holes, depending on the type of wall: concrete, brick, wood, etc.;

- a need for different technology and types of dowels for different wall materials;

- the dowel length has to be conformable to the insulation thickness;

- a need for use of specialized power tools - drills or hammers.

SUMMARY OF THE INVENTION

The task of the invention is to create a means for fixing of insulation to a constructive or decorative component of mechanically fixed cladding, which does not compromise the elements of the basic construction of the building, to which the insulation is attached; in other words, be non-invasive to the building structure and optimize the insulation fixing process.

This task is solved through the creation of a non-invasive fixing device for fixing of building insulation to a constructive or decorative component of mechanically fixed cladding, comprising consequently arranged along the longitudinal axis of the fixing device a supporting element for penetration of insulation, a transverse pressing disc for pressing of insulation and a fixing element. The fixing element is configured to be fixed to a load-bearing profile subconstruction or cladding panel.

The supporting element is a needle with a length less than or equal to the thickness of the insulation.

It is advisable to have an adjustment part between the fixing and the supporting element, to which the pressing disc is fixed in an adjustable manner and with an option to fix in different positions along the adjustment part. In one variant of execution, the adjustment part has a shallow cylindrical thread, while the pressing disc has a central bore with a thread, in which case the pressing disc is installed with its central bore towards the cylindrical thread of the adjustment part. Alternatively, it is possible for the adjustment part to have a shallow cylindrical thread and to be installed with its central bore through the use of an additional device with a threaded bore to the cylindrical thread of the adjustment part. Another alternative is that the adjustment part could represent an area with cross transverse ring-shaped ribs, placed at distance intervals from one another along the adjustment part, that distance being larger than the thickness of the pressing disc, while the pressing disc has a slot with a width less than the outer diameter of the transverse ring-shaped ribs and larger than the diameter of the adjustment part.

In an implementation option of the invention, the fixing element is represented by a mount for attachment to a load-bearing profile subconstruction or a cladding panel. Another option is that the fixing element could be a foot mount for support against a cladding panel.

An additional task for the invention is the creation of a system, including the non- invasive fixing device for fixing of isolation, in relation to the invention.

This task is performed through the creation of a system for non-invasive fixing of building insulation to a constructive or decorative component of mechanically fixed cladding, including insulation, at least one insulation fastener, a load-bearing profile subconstruction, located on the opposite side of the insulation that faces a main construction element of a building and at least one cladding panel, fixed to the load-bearing profile subconstruction. The aforementioned (at least) one insulation fastener is represented by a non-invasive fixing device for fixing of building insulation, in accordance with the invention, in which the needle of the non-invasive fixing device for fixing of insulation is inserted into the insulation at a depth less than or equal to the thickness of the insulation, while through the use of a fixing element, the non-invasive fixing device for fixing of insulation is installed and fixed to the load-bearing profile subconstruction or to at least one of the cladding panels. An additional task of the invention is the creation of a method for fixing of insulation through the non- invasive fixing device for fixing of insulation, according to the invention.

That task is accomplished through the creation of a method for non-invasive fixing of building insulation to a constructive or decorative component of mechanically fixed cladding, including the stages of: placing an insulation element to a load-bearing construction element of a building; fixing the insulation element through a non-invasive fixing device for fixing, in accordance with the invention, in which the needle of the fixing device is inserted in the insulation element, so that it is located at a distance from the load-bearing construction element of a building; attaching the fixing element of the fixing device to a profile of a load-bearing profile subconstruction or cladding panel.

The non-invasive fixing device for fixing can have an adjustable pressing disc, as described above, preferably after the insertion of the needle into the insulation and the fastening of the fixing element, the adjustable pressing disc to press against the outer surface of the insulation element until its full jam to the load-bearing construction element of the building and to be locked in the respective position along the non-invasive fixing device for fixing.

The advantages of the non-invasive fixing device for fixing of insulation, according to the invention, as well as the system that includes such a device and the method for fixing such a device, are:

- The insulation is fixed to the cladding substructure, not to the basic structure of the building, therefore it is achieved without invasion of the main structure of the building; - The time for fixing is decreased, because the insulation is fixed without drilling holes into the main structure, which takes the most amount of labour time in the insulation fixing process, especially for concrete constructions;

- The labour productivity is increased due to a smaller number of operations needed for insulation fixing;

- An opportunity for easy repairs and easy insulation replacement if needed, only through disassembly and then reassembly of the used devices for fixing of insulation;

- An opportunity to use the best insulation materials for the production of the needles of the insulation fixing device, for improvement of the overall insulation system of the building;

- An opportunity to use strong construction materials for fixing and adjustable elements of the system, which improves the overall strength of the facade;

- An opportunity for better control of the insulation fixing process.

The non- invasive fixing device for fixing of building insulation, in accordance with the invention, is fixed to a constructive or decorative component of mechanically fixed cladding. Main constructive building elements are foundations, walls, floors, partition plates, stairs.

The non-invasive fixing device for fixing of building insulation includes a supporting element for penetration of insulation, which is essentially a needle (1) with a length less than or equal to the thickness of the insulation. The needle is an elongated element with a smooth surface and sharp point. In an example implementation of the invention, the needle (1) is made of reinforced insulation material. In particular, the needle (1) can be made of stainless steel, aluminum, plastic, or composite combination thereof, such as steel core with plastic coating, or other suitable material. The needle is connected at one end to a transverse pressing disc (2) for pressing against insulation. The pressing disc (2) can be made of plastic or other suitable material. After the pressing disc (2), the device for fixing has a fixing element, configured to be fixed to a load-bearing profile subconstruction or cladding panel.

The fixing element can be a mount (3) for fixing to a load-bearing profile subconstruction or cladding panel (fig. 1), or alternatively, a foot mount (5) for support against a cladding panel (fig. 2). The mount (3) for fixing to a load-bearing profile subconstruction or cladding panel can be made of plastic, aluminum, stainless steel or other suitable material. The foot mount (5) can be made of aluminum, stainless steel or other suitable material. The mount can be fixed, for example, to a load-bearing profile or to a slot, cut in the thickness of the cladding panel. A foot mount (5) is used for non-loaded insulation pressing systems in places, where there is a need for additional pressing and can be supported by, for example, the back of the cladding panel. In alternative example implementations of the invention, the fixing element can be a bracket, a bracket with a screw, a clip, a hook, a plate with a screw or another type of construction for fixing to a constructive or decorative component.

Between the fixing element and the needle is an adjustment part (4), to which the pressing disc (2) is mounted in an adjustable manner and with an option to locking in different positions along the adjustment part (4). The adjustment part (4) can be made of stainless steel, aluminum, plastic, or composite combination thereof, such as steel core with plastic coating, or other suitable material. The choice of material is usually corresponding to the material the needle (1) is made of.

The adjustment part (4) can be executed in different ways, such as:

1 ) The adjustment part (4) can have a shallow cylindrical thread. In this variant, the pressing disc (2) is installed with its central bore towards the cylindrical thread of the adjustment part (4).

2) The adjustment part (4) can have a shallow cylindrical thread. In this variant, the pressing disc (2) has a central bore and is mounted with its central bore through an additional device with a threaded bore to the cylindrical thread of the adjustment part (4).

3) The adjustment part (4) can represent an area with transverse ring-shaped ribs, placed at a distance between them along the adjustment part (4), that distance being larger than the thickness of the pressing disc (2). In this variant, the pressing disc (2) has a slot with a width less than the outer diameter of the transverse ring-shaped ribs and larger than the diameter of the adjustment part (4) (fig. 1), while the pressing disc (2) is threaded with its slot sideways to the adjustment part (4) between two ring-shaped ribs.

The non- invasive fixing device for fixing of insulation can be a part of a system for non-invasive fixing of building insulation to a constructive or decorative component of mechanically fixed cladding, which includes more insulation, a loadbearing profile subconstruction, located on the insulation side, facing towards a main construction element of a building and at least one cladding panel, fixed to the load- bearing profile subconstruction. The needle (1) of the non- invasive fixing device for fixing of insulation is inserted into the insulation at a depth less than or equal to the thickness of the insulation in a way that it does not touch the construction element of the building, to which the insulation is applied. Through a fixing element, the non- invasive fixing device for fixing of insulation is attached and fixed to the loadbearing profile subconstruction or to at least one cladding panel.

In the case of the method for non-invasive fixing of building insulation to a constructive or decorative component of mechanically fixed cladding, in accordance with the invention, the following steps are taken:

- Placing of insulation element to a main construction element of a building;

- Fixing of insulation element through the non-invasive fixing device for fixing, in accordance with the invention, in which the needle (1) of the fixing device is inserted into the insulation element, while it is not necessary to pierce a hole beforehand, so that the tip of the needle (1) is located at a distance from the main constructive element of the building;

- In case the non-invasive fixing device for fixing of insulation includes an adjustable pressing disc (2), after the insertion of the needle (1) into the insulation and the attaching of the fixing element, the adjustable pressing disc (2) is pressed against the outer surface of the insulation element until its complete press against the main constructive element of the building and is fixed in the respective position along the adjustment part (4) of the non-invasive fixing device for fixing;

- Attachment of the fixing element of the device for fixing to a profile of a loadbearing profile subconstruction or cladding panel. In the example implementation of the invention, where the fixing element of the non-invasive fixing device for fixing is a mount (3), it is attached to the load-bearing profile subconstruction of cladding panel with a screw, a groove, a hook-like adapter or another fixing device, depending on the mount construction in question (3). In the example implementation of the invention, in which the fixing element of the non- invasive fixing device for fixing is a foot mount (5), it presses against a cladding panel.
