Profile for installing a non-bearing exterior wall for a building, non-bearing wall for a building comprising at least one profile of this type and a building comprising a non-bearing exterior wall of this type

The invention relates to a profile for constructing a non-bearing exterior wall for a building, to a non-bearing exterior wall for a building comprising at least one profile of this type, and to a building comprising at least one non-bearing exterior wall of this kind.

The invention especially relates to a profile for constructing a non-bearing exterior wall for a building in the form of a dry construction wall. Walls of this type erected in a dry construction comprise a substructure, which is also called a framework, and which is covered on both sides with construction panels.

For such a wall erected in a dry construction substructures are known especially in the form of metal stud structures of metal profiles, these studs metal studs of metal profiles are also referred to as metal truss. Metal profiles on both sides are also called CW profiles. These CW profiles are arranged vertically and are joined at one end and on the other respectively by metal profiles that are fixed in the roof area ^or in the floor area of a building. These metal profiles fixed on the deck side and on the ground side, which are essentially horizontally oriented, are also called UW profiles.

L ^os building panels with these trusses are initiated by the two sides is known especially as building panels together with cement, so - called building panels cement and building panels together with gypsum, so - called building panels of plaster.

While gypsum building boards or cement building panels are used for wall surfaces directed into an interior space of a building, cement building panels may be used especially for exterior walls, i.e. representing the wall surface facing out from an exterior wall of a building. On their upper surface on the outer side, the cement building panels may have, for example, a plaster, a brick-clad upper surface, or may also be, for example, plastered and colored.

In dry construction, the effectiveness of suitably structured exterior walls on both sides has mainly been demonstrated. However, heat transfer through such an exterior wall constructed in a dry construction may present a problem. A ^yes, I ^I metal profiles of the substructure represent a good thermal conductor, through which heat is transferred from the building panel of the outer wall directed to the interior space to the building panel directed to the outer space by profiles Ios metal and Finally, this construction panel can be released into the environment.

To reduce heat transfer through an exterior wall, it would therefore be necessary to reduce heat transfer by means of the profile.

DE 102 16675 B4 discloses a soundproofing profile consisting of two profile flanges that are connected to each other by means of an acoustic decoupling arrangement that surrounds ^the adjacent edges of the profile flanges, the arrangement being acoustic decoupling connected to the profile flanges by friction drag. However, this friction drag allows some sliding friction and therefore reduces the stiffness of the profile.

From document US5609006 a stud profile is known which consists of two profile slats that are joined by means of central elements that can be moved vertically.

The invention is based on the objective of providing a profile to raise a non-bearing exterior wall for a building that has low thermal conductivity. The invention is especially based on the aim of providing a profile of this type that has a lower thermal conductivity than that of a metal profile.

Another object of the invention is to provide such a profile that has high strength and especially also high stiffness.

Another object of the invention is to provide such a profile that can be manufactured quickly and easily.

Another object of the invention is to provide such a profile that can be manufactured with little technical effort and especially also cheaply.

To solve the invention, a profile is provided to raise a non-bearing exterior wall for a building, the profile comprising the following characteristics:

two metal profile slats, which are arranged in parallel and with the configuration of a gap between the profile slats with a space relative to each other, the profile slats respectively having a groove that has its path along the cleft

connecting elements of a material that have a lower thermal conductivity than the metal of the profile slats, and by means of which the two profile slats are mechanically connected to each other, several connecting elements being inserted along the slit and with a space with respect to each other, respectively, making the slit a bridge towards the interior of the grooves of the two profile slats, and the connecting elements each engaging in the two grooves, the joint being by In each case, the socket is configured by a housing configured in the grooves, in which the connecting elements are each fitted with a corresponding socket projection, and the housings are respectively configured in the grooves, respectively configured as an opening.

A fundamental idea of the invention is to provide, in the case of a profile that can be joined on both sides for a profile upright structure to raise a non-bearing exterior wall in a dry construction, a slot that has its path along the longitudinal extension of the profile, a gap through which the metal profile is separated into two profile slats, the two profile slats being connected to one another by a multitude of connecting elements with low thermal conductivity and each of the connecting elements being hooked on both profile slats. The invention is also based in particular on the surprising fundamental discovery that two profile slats spaced from the profile can be connected to one another in such a way by means of connecting elements, each of which is fitted with the profile slats, which, On the one hand, the profile has a low thermal conductivity and, on the other hand, at the same time they have a high resistance and especially also a high stiffness. Such a snap connection, by means of which the connecting elements are respectively connected to the profile strips, can be configured particularly easily and, in particular, also economically. Especially to configure such a snap joint, no further components are needed, such as adhesive ^or other fixing means, to join the two profile slats to each other. At the same time, the two profile bars are thermally separated by means of the connecting elements, especially since the connecting elements are made of a material that has a lower thermal conductivity than the metal of the profile bars. Since the connecting elements are made of a material with a lower thermal conductivity than the metal of the profile bars, the profile bars are thermally decoupled by means of the intercalated connection elements, so that the profile according to the invention in set features low thermal conductivity from profile lath to profile lath.

Plastic connecting elements are preferably provided. An advantage of plastic connecting elements is that plastic has a low thermal conductivity, especially a lower thermal conductivity than metal. Another advantage of plastic connecting elements is that these plastic connecting elements can be easily and cheaply manufactured, for example, by injection molding. In accordance with the invention, a fiber-reinforced plastic composite material has turned out to be an especially preferred material for joint elements. Therefore, particularly preferably, connecting elements of such a material made of fiber-reinforced plastic are provided. According to a particularly preferred embodiment, there is provided a composite material of plastic reinforced with fibers of a plastic in the form of polyamide and fibers in the form of fiberglass. Preferably, the percentage of fiberglass in such a material made of polyamide fiberglass is in the range of 30 to 70% by mass, relative to the total mass of the fiber-reinforced plastic composite material, especially in 50% of the mass.

The connecting elements can be configured, for example, in the form of inserts, especially, for example, in the form of a plate, especially with an outer contour that has its path essentially in the shape of a rectangle.

According to a particularly preferred embodiment, the connecting elements are respectively configured in one piece, particularly preferably as an injection molded part configured in one piece. These one-piece composite materials, especially as an injection molded part, can be provided very easily and inexpensively, especially also in the form of a fiber-reinforced plastic composite material.

According to an embodiment, all the connecting elements are configured in the same ^or identical form. This has the advantage that only one type of connecting element should be used to join the profile bars. This is advantageous, on the one hand, from an economic point of view. Furthermore, this is also advantageous from a constructive point of view, since, for example, in the manufacture of the batten, there can be no confusion or change of different joining elements, so that errors in the manufacture of the profile can be avoided with the invention.

According to the invention, it has been shown that a profile strip according to the invention can be provided with an already high mechanical strength and rigidity if the two profile profile strips are joined by means of thin connecting elements. For example, provision can be made for the connecting elements, especially ^{plate-shaped connecting elements, to have a thickness in the range of} 1 ^to 8 ^{mm to facilitate a} profile according to the invention with high strength and rigidity. In this sense, provision can be made for ^{the connecting elements to have a thickness in the range of} 1 ^to 8 ^{mm, preferably in the range of} 2 ^to 6 mm. According to a particularly preferred embodiment, the thickness of the connecting elements is 4 mm.

According to the invention, it has been shown that the thermal decoupling of the two profile slats from the profile can be further improved if the connecting elements respectively have at least one opening or respectively at least one hole. Preferably the connecting elements can respectively have several orifices or several openings of this type in order to further reduce heat transfer by means of the connecting elements. Corresponding holes ^or openings may especially be provided in the connecting elements as long as they are made of a fiber-reinforced plastic composite material configured as indicated above, since such a material has sufficient strength to securely bond one with another the two profile slats also with these configured openings.

Each of the connecting elements bridges the gap between the two profile bars and each one is inserted in the groove of each of the two profile bars, each of the connecting elements being hooked, in addition, in each of the two slots respectively.

The connecting elements may in particular have two sections, each with one of these sections being inserted into one of the two grooves of the profile slats respectively. Preferably, the connecting elements respectively have, in two opposite zones, a section with which they are each inserted into the groove of the profile slats. These sections, with which the connecting elements are each inserted in the grooves of the profile bars, can respectively be spring-shaped. In this sense, the connecting elements form a spring-groove connection with the two grooves, respectively.

To configure the coupling of the connecting elements in the grooves, the connecting elements can be hooked in each of the two grooves by means of at least one snap connection. T ^he engaging means of the joining elements can be formed in sections or Ios springs mentioned above, in which Ios Ios connecting elements are inserted in each slot.

Particularly preferably, ^{the connecting} elements are each fitted into each of the two grooves by means of at least two snap-fit joints. According to the invention, it has been shown that the profile according to the invention has an especially high resistance, in particular an especially high rigidity, when ^{the connecting} elements are each fitted in each of the two grooves by means of at least two joints per socket. Then, according to the invention, it has been shown that you can practically completely ruled out that Ios connecting elements move or shift into the slots if I ^os connecting elements are engaged in each of the slots I ^will slats profile by means of at least two snap joints.

Particularly preferably, the snap fittings by means of which the ^fastening elements are each snapped into each of the grooves are configured separate from each other. According to one embodiment, there is at least one snap connection configured respectively in each of the two opposite end zones of the section (or spring) of the connection element with which the connection element is inserted in a groove respective.

In accordance with the invention, the snap fittings are respectively configured by a slot shaped housing, in which the fastener elements are each snapped into place with a corresponding snap boss. According to the invention, the housing is configured in the slot respectively as an opening, that is, as a window or as a recess in the slot. These openings in the grooves are particularly easy to configure from the point of view of manufacturing technique, for example by punching. Particularly preferably, these openings respectively have a rectangular cross section, for example a square cross section. A special advantage of the housings in the form of openings of this type in the grooves with a rectangular section respectively resides especially in the fact that for openings of this type, a corresponding snap-in projection can be configured with special facilitation in the connecting element, whereby the connecting element can be fitted into the opening in the configuration of a snap connection.

According to a particularly preferred embodiment, the ^socket projections are provided on ^{the connecting} elements in the form of socket beads, that is, in the form of clips that can be snapped or fastened in the housings configured in the grooves. A special advantage of these lace protrusions in the form of lace heels resides especially also in the fact that they can be formed particularly easily in the connecting element by injection molding. In the case of these lace heels, the lace connection is thus configured in the form of a so-called clip closure.

According to the invention, in order to form a snap connection with the profile slats, the connecting elements have opposite snap beads, which can each fit into groove housings. In other words, in this embodiment the connecting elements have opposing housings respectively on both sides (in relation to the main upper surface of a connecting element, especially in the form of an insert or plate). In this sense, the grooves can also have opposite housings, especially opposite openings into which each of the snap beads fit.

According to a preferred embodiment, the connecting elements have stops with which they abut against the profile slats. Each connection element has, in this sense, at least two stops, each connection element respectively hitting at least one stop against each of the profile slats. Since, in this sense, the connecting element is engaged with the profile strip and at the same time abuts the profile strip by means of a stop, a defined fixed seating of the connecting elements on the profile strips is guaranteed, connecting elements by means of which it is possible to prevent the connecting elements from moving ^or moving towards the profile slats. Therefore, these stops especially also have the advantage that the strength, especially the stiffness of the profile according to the invention, can continue to increase.

L ^os stops on the connecting elements can be provided, for example, as edge ^or surface. In order to configure such an edge, sections can be configured on the connecting elements that have corresponding edges, which form a stop with which the connecting element abuts against the respective profile strip. For example, these sections in which the stops are configured may be configured in the form of protruding sections, for example in the form of protruding ribs or protrusions. With an edge or a surface of these ribs or projections the connecting element abuts against the profile slats in a state engaged with the profile slats, whereby these ribs ^or projections form a stop with which the connecting elements abut against profile slats.

According to a particularly preferred embodiment, the stops abut respectively against the sides of the profile slats facing the slit. This embodiment has the advantage in particular that no special elements must be configured on the profile slats against which the connecting elements come into contact with their stops.

According to one embodiment, it is provided that the connecting elements are retained in the grooves by force dragging (by friction dragging). For this purpose, it can be provided, for example, that the grooves are configured - at least partially - with a groove width slightly less than the thickness of the sections of the connecting elements, configured in the manner described above, in particular in the form of a spring , sections with which the connecting elements can be inserted in the grooves of the profile slats. In this way there is an adhesion between the contact surfaces of the grooves and the connecting elements (or the grooves and the sections / springs of the connecting elements), so that the connecting elements, beyond the joint by they are retained in the grooves additionally by friction drag, whereby the joining of the profile slats by means of the connecting elements continues to improve and especially continues to become more rigid. In this sense, it is also advantageous that the profile slats are made of metal, since, due to their elastic properties, it is exceptionally well suited to the configuration of a friction drag connection.

An essential fundamental idea of the profile according to the invention is also that the connecting elements are arranged relative to one another with a space. Since the connecting elements are arranged with respect to one another with a space, a gap ^or a recess is respectively formed between the connecting elements. This gap between the connecting elements especially favors an optimization of the balance of the moisture content (circulation) of a raised external wall using the profile according to the invention. This circulation is especially advantageous in the case of an outer wall comprising components that can be negatively influenced by humidity, for example, by condensation water. These components can be, for example, gypsum construction panels or panels derived from wood, ^or also insulating materials that are arranged in the free space between the construction panels.

Another advantage of these connecting elements arranged separately from each other is an additional material saving.

According to one shape of configuration, the grooves and housings configured in the grooves are configured in the same way along the groove. Thus, in this embodiment neither the design of the grooves, nor the design nor the arrangement of the housings along the slit are modified. In this embodiment, the housings have, in particular, an equal dimension, respectively, the same distance from the slot opening and the same distance from each other. On the one hand, this has the advantage that for a profile according to the invention only a single type of element can be used. joint that can be used to join the profile slats at a discretionary point, since the profile slats are correspondingly configured in the same way. Another advantage is that the resistance behavior of the profile in this configuration with the same shape of the profile slats remains unchanged throughout the length of the profile, so that the profile guarantees a very homogeneous load absorption throughout its length. Finally, another advantage of ^the profile slats with the same shape correspondingly resides in that they can be manufactured with special facilitation regarding the manufacturing technique.

According to a preferred embodiment, the profile slats are configured axially symmetrical, especially axially symmetrical with respect to an axial plane that has ^its path through the slit separating the profile slats.

The profile slats are made of metal, preferably steel or an alloy steel. According to one embodiment, the profile slats are composed of construction steel, especially metal-clad construction steel.

L ^os profile strips may have been formed by deformation from a metal lamina, especially by rolling rollers. By means of rolling by rollers, it is possible, with special ease, to configure the profile slats with the same shape due to the length of the profile slats.

L ^os profile strips have an area in which grooves are formed respectively. These grooves are configured along the gap that separates the profile slats. the grooves can be specially made by metal deformation. The areas of the profile slats in which the grooves are respectively configured may be configured preferably directed towards each other and, particularly preferably, in one plane. Particularly preferably, the grooves of the two profile slats have their path in a common plane. This has the particular advantage that Ios connecting elements are in this plane can be introduced into the two slots I ^os profile strips.

The profile slats can respectively have areas extending at right angles from these areas in which the grooves are configured. These zones can be specially configured for building panel decking. For this purpose, these zones can, for example, holes ^or other means which may be I ^I screwed or fixed building panels. These areas Ios profile strips which can be set I ^os building panels preferably extend in the same direction. These areas can preferably be bent by deformation from the areas in which the grooves are arranged.

Since the areas where I ^os building panels can be set to I ^os slats profile can connect other areas extending at right angles to the areas where I ^os building panels may be attached to I ^os laths Profile. Preferably, these areas of ^the profile slats can extend towards each other and have ^their route, particularly preferably, in a common plane. These areas can especially serve to reinforce ^the profile bars ^or the profile according to the invention. These other areas can also be preferably bent by deformation from the areas in which the construction panels can be attached to ^the profile slats.

Ios set profile strips may occur, in this regard, a cross section essentially U-shaped, the apertures being shaped respective U I ^I slats each other directed profile.

The connecting elements can respectively have a thermal conductivity in the range of 0.1 to 5 W / mK, more preferably in the range of 0.2 to 1 W / mK, and even more preferably in the range of 0.2 at 0.5 W / mK. The thermal conductivity of ^{the connecting} elements can be determined in accordance with DIN EN ISO 22007-1: 2012-04.

The profile slats can respectively have a thermal conductivity in the range of 10 to 100 W / mK, for example also in the range of 20 to 80 W / mK. The thermal conductivity of the profile bars can be determined in accordance with DIN 4108-4: 2017-03, in conjunction with DIN EN ISO 10456: 2010-05.

The profile according to the invention can have a thermal conductivity in the range of 0.02 to 0.2 W / mK, more preferably in the range of 0.03 to 0.2 W / mK and even more preferably in the range of 0.04 to 0.1 W / mK. The profile according to the invention can in particular have a thermal conductivity from the area of one of ^the profile strips to ^{the one} that a construction panel can be attached to the area of ^the other profile strips to ^{the one} that can be fixed a construction panel, to the extent mentioned above. The thermal conductivity of the profile can be determined according to DIN 4108-2: 2013-02.

In sections 41, 42, each of the connecting elements 40 respectively has two snap beads 43.1a, 43.1b; 43.2a, 43.2b; 44.1a, 44.1b; 44.2a, 44.2b in zones of sections 41,42 distally separated. These lace heels 43.1a, 43.1b; 43.2a, 43.2b; 44.1a, 44.1b; 44.2a, 44.2b are dimensioned and separated from each other in such a way that they fit into grooves 11, 21, configuring snap-fit joints in cavities 12, 13; 22, 23 when the connecting elements 40 are inserted with ^their sections 41,42 respectively in the grooves 11, 21.

As the connecting elements 40 are inserted with each of the two sections 41, 42 respectively in the grooves 11, 21 of the profile slats 10, 20, the profile slats 10, 20 are mechanically joined to each other by means of The connecting elements 40. At the same time the connecting elements 40 are hooked, by means of the snap lugs 43.1a, 43.1b; 43.2a, 43.2b; 44.1a, 44.1b; 44.2a, 44.2b, with the housings 12, 13, 22, 23 configured, correspondingly to these, in the grooves, configuring a snap connection in the grooves 11, 21.

As ^{the connection} elements 40 have a lower thermal conductivity than that of ^the profile bars 10, 20, ^the profile bars 10, 20 are thermally separated from each other, at the same time, by ^{the connection} elements 40.

In this regard, I ^will connection elements 40 are formed along the slit 30 with a distance relative to each other, so that between I ^os connecting elements 40 is respectively one 50. recess grooves 11, 21 have respectively, in the area of the groove bottom, a groove width of 4 mm, which corresponds to the thickness of the sections 41, 43. This groove width is respectively reduced slightly towards the opening of the grooves 11, 21. From In this way, sections 41, 43 are located, in addition to the snap connection described above, further retained in grooves 11, 21 by friction drag. The connecting elements 40 have stops 45a, 45b; 47a, 47b respectively abut against Ios Ios that profile strips 10, 20. In this connection, each connecting element 40 abuts respectively with two abutments 45a, 45b ^or 47a, 47b against one of R ^os profile strips 10, 20 respectively when the connecting element 40 respective is engaged with I ^os two strips of profile 10, 20. T ^he stops 45a, 45b with I ^will each connecting element 40 impinges on the profile strip 10 are configured in two ribs 46a, 46b which are configured on the opposite main upper surfaces in the connecting element 40. In this regard, ^the stops 45a, 45b respectively form an edge of the respective rib 46a, 46b. Correspondingly, each connecting element 40 abuts two stops 47a, 47b on the profile strip 20, these stops 47a, 47b correspondingly configured as rib edges 48a, 48b arranged on opposite sides of the connecting element 40.

In the two end zones I ^os longitudinal sides of I ^os slats profile 10, 20 is introduced in each case into the slots 11, 21 Ios slats profile 10, 20 a square metal 60 (in Figure 10 onIy is depicted lower 60 metal bracket). These metal brackets 60 serve to fix the profile 1 to the ground and to the roof of a building (not shown).

In FIG. 10 a section of a non-supporting exterior wall 100 for a building is shown.

The exterior wall 100 comprises a gypsum construction panel 110 directed to an interior space I of the building and a cement construction panel 120 directed to an exterior space A. The gypsum construction panel 110 and the cement construction panel 120 they are arranged in parallel with respect to each other configuring a free space 130. In this regard, the gypsum construction panel 110 and the cement construction panel 120 are joined to each other by means of two profiles 1, according to the figures 1 to 9, such that said clearance 130 is between the gypsum building panel 110 and the cement building panel 120. The gap 130 is filled with an insulating material 140 in the form of mineral wool.

The gypsum construction panel 110 and the cement construction panel 120 are screwed respectively to the profile slats 10, 20 by means of screws 150. Specifically, the gypsum construction panel 110 and the cement construction panel 120 are screwed , by means of ^the screws 150, to the zones 15, 25 of ^the profile slats 10, 20, which extend at right angles from the zones 14, 24 of the profile slats 10, 20 in which they are configured grooves 11, 21.
