Description

The invention relates to a profile for the construction of a non-supporting outer wall for buildings, a non-supporting outer wall for buildings, which comprises at least one such profile, and a building which comprises at least one such non-supporting outer wall.

In particular, the invention relates to a profile for the construction of a non-supporting outer wall for buildings in the form of a drywall.

Such drywall walls include a substructure, also referred to as a stud work, which is planked with structural panels on both sides.

Substructures for such a wall created in drywall are in particular in the form of metal stud constructions Metal profiles known, wherein such metal stud structures made of metal profiles are also referred to as metal studs. Both sides planked metal profiles are also referred to as CW profiles. Such CW profiles are arranged vertically and connected on the head and foot side respectively with metal profiles which are fixed in the area of the ceiling or in the region of the floor of a building. Such ceiling and bottom-mounted metal profiles, which are aligned substantially horizontally, are also referred to as UW profiles.

Building boards, with which such studs are planked on both sides, are known in particular in the form of cement-bonded construction boards, so-called cement boards, and gypsum-bonded construction boards, so-called plasterboard.

While for the interior of a building facing surface of a wall plasterboard or Zementbauplatten be used, cement boards can be used in particular for exterior walls, so represent the outward facing wall surface of an exterior wall of a building. For example, on their outside surface cement boards may have a plaster, a surface with clinker straps or, for example, also be filled and provided with paint.

Basically, appropriately constructed, both sides planked outer walls in drywall have proven. However, a problem can be the heat transfer through such an exterior wall made in drywall construction. Thus, the metal profiles of the substructure represent a good heat conductor, on the heat from the facing the interior wall panel of the outer wall over the Metal profiles transferred to the exterior space facing building board and can be discharged from this building board finally to the environment.

To reduce heat transfer through such outer wall, it would therefore be necessary to reduce heat transfer across the profile.

Out DE 102 16 675 B4 a soundproofing profile is known, which consists of two profile flanges, which are connected to one another via the adjacent edges of the profile flanges embracing sound decoupling arrangement, wherein the sound decoupling device is connected via frictional engagement with the profile flanges. However, such a friction allows a certain sliding friction and therefore reduces the stiffness of the profile.

Out US5609006 is a stand profile known, which consists of two profile strips, which are connected via vertically displaceable core elements.

The invention has for its object to provide a profile for the construction of a non-supporting outer wall for buildings available, which has a low thermal conductivity. In particular, the invention has for its object to provide such a profile available, which has a lower thermal conductivity than a profile made of metal.

A further object of the invention is to provide such a profile which has a high strength and in particular also a high rigidity.

Another object of the invention is to provide such a profile which is quick and easy to manufacture.

Another object of the invention is to provide such a profile available, which is inexpensive to produce with little technical effort and in particular.

• Zwei Profilleisten aus Metall, die parallel und unter Ausbildung eines Spaltes zwischen den Profilleisten mit Abstand zueinander angeordnet sind, wobei die Profilleisten jeweils eine entlang des Spaltes verlaufende Nut aufweisen;
• Verbindungselemente aus einem Werkstoff, der einer geringere Wärmeleitfähigkeit aufweist als das Metall der Profilleisten, und über die die zwei Profilleisten mechanisch miteinander verbunden sind, indem mehrere Verbindungselemente entlang des Spaltes und mit Abstand zueinander jeweils unter Überbrückung des Spaltes in die Nuten beider Profilleisten gesteckt sind, und wobei die Verbindungselemente jeweils in beiden Nuten verrastet sind, wobei die Rastverbindung jeweils ausgebildet ist durch eine in den Nuten ausgebildete Aufnahme, in die die Verbindungselemente jeweils mit einem korrespondierenden Rastvorsprung einrasten, und wobei die in den Nuten jeweils ausgebildeten Aufnahmen jeweils in Form einer Öffnung ausgebildet sind.

To achieve the invention, there is provided a profile for constructing a non-supporting exterior wall for buildings, the profile comprising the following features:

• Two metal moldings, which are arranged in parallel and with formation of a gap between the profile strips with a distance from each other, wherein the profile strips each have a groove extending along the gap;
• Connecting elements made of a material having a lower thermal conductivity than the metal of the profile strips, and over which the two profile strips are mechanically interconnected by a plurality of connecting elements along the gap and at a distance from each other while bridging the gap in the grooves of both moldings are inserted and wherein the connecting elements are each latched in two grooves, wherein the latching connection is formed in each case by a recess formed in the grooves, into which the connecting elements each engage with a corresponding latching projection, and wherein each of the grooves formed in the receptacles in the form of an opening are formed.

A basic idea of the invention is to provide a gap extending along the longitudinal extension of the profile in a profile for a metal stud construction erecting a double-walled profile for erecting a non-supporting outer wall by which the metal profile is divided into two profiled strips, wherein the two profiled strips have a plurality are interconnected by connecting elements with a low thermal conductivity and wherein each of the connecting elements is locked in two profile strips. The invention is particularly based on the surprising Basic knowledge that the two spaced profile strips of the profile via connecting means, which are respectively locked with the profile strips, can be connected to each other such that the profile has on the one hand only a low thermal conductivity and on the other hand at the same time has a high strength and in particular a high rigidity , Such a latching connection, via which the connecting elements are respectively connected to the profile strips, can be designed to be particularly simple and, in particular, inexpensive. In particular, no further components, such as glue or other fastening means necessary to connect the two moldings with each other to form such a locking connection. At the same time, the two profile strips are thermally separated via the connecting means, in particular in that the connecting elements consist of a material which has a lower thermal conductivity than the metal of the profile strips.

Since the connecting elements consist of a material with a lower thermal conductivity than the metal of the profile strips, the profile strips are thermally decoupled by the interconnected connecting elements, so that the profile according to the invention has a low overall thermal conductivity of profile strip to profile strip.

Preferably, plastic connecting elements are provided. An advantage of connecting elements made of plastic is that plastic has only a low thermal conductivity, in particular a lower thermal conductivity than metal. Another advantage of plastic fasteners is that such plastic fasteners can be easily and inexpensively produced, for example by injection molding. As special preferred material for the fasteners according to the invention, a fiber-plastic composite has been found. Particular preference is therefore given to connecting elements made of such a fiber-plastic composite material. According to a particularly preferred embodiment, a fiber-plastic composite material made of a plastic in the form of polyamide and fibers in the form of glass fibers is provided. Preferably, the proportion of glass fibers in such a polyamide-glass fiber composite material in the range of 30 to 70 mass%, based on the total mass of the fiber-plastic composite material, in particular at 50% by mass.

The connecting elements may, for example, be platelet-shaped, in particular, for example, tabular, in particular with a substantially rectangular outer contour.

According to a particularly preferred embodiment, the connecting elements are each formed in one piece, particularly preferably as an integrally formed injection molded part. Such integrally formed, in particular as an injection molded part composites can be made very simple and inexpensive available, especially in the form of a fiber-plastic composite material.

According to one embodiment, all connecting elements are uniform or identical. This has the advantage that only a single type of fasteners must be used to connect the moldings. On the one hand, this is advantageous from an economic point of view. Furthermore, this is also advantageous from a design point of view, since, for example, in the production of the profile strip to no confusion or confusion different fasteners can come, so that errors in the production of the profile according to the invention can be prevented.

According to the invention, it has been found that a profiled strip according to the invention with an already high mechanical strength and rigidity can be made available if the two profile strips of the profile are connected via connecting elements with only a small thickness. For example, it may be provided that the connecting elements, in particular plate-shaped connecting elements, only have to have a thickness in the range of 1 to 8 mm in order to provide a profile according to the invention with a high strength and rigidity. In that regard, it can be provided that the connecting elements 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 found that the thermal decoupling of the two profiled strips of the profile can be further improved if the connecting elements each have at least one opening or in each case at least one hole. Preferably, the connecting elements may each have a plurality of such holes or openings in order to further reduce the heat transfer through the connecting elements. In particular, corresponding holes or openings in the connecting elements can then be provided, as far as they are formed from a fiber-plastic composite material formed as above, since such a material has sufficient strength to even with such trained openings to connect the two moldings firmly together.

Each of the connecting elements bridges the gap between the two profiled strips and is in each case inserted into the groove of each of the two profiled strips, wherein each of the connecting elements is further latched in each of the two grooves in each case.

The connecting elements may in particular have two sections, wherein they are respectively inserted with one of these sections in each case one of the two grooves of the profile strips. Preferably, the connecting elements at two opposite areas each have a portion with which they are respectively inserted into the groove of the profile strips. These sections, with which the connecting elements are respectively inserted into the grooves of the profile strips, may each be designed in the form of a spring. In this respect, the connecting elements with the two grooves each form a tongue and groove connection.

To form the latching of the connecting elements in the grooves, the connecting elements can each be latched via at least one latching connection in each of the two grooves. The locking means of the connecting elements may be formed on the aforementioned sections or springs, on which the connecting elements are respectively inserted into the grooves.

Particularly preferably, the connecting elements are latched in each case via at least two latching connections in each of the two grooves. According to the invention, it has been found that the inventive Profile has a particularly high strength, in particular a particularly high rigidity, when the connecting means are locked in each case via at least two latching connections in each of the two grooves. Because according to the invention it has been found that slipping or displacement of the connecting elements in the grooves can be practically completely excluded when the connecting elements are latched via at least two locking connections in each of the grooves of the profile strips.

Particularly preferably, the latching connections, via which the connecting elements in each of the grooves are respectively latched, spaced from each other. According to one embodiment, in each case at least one latching connection is formed on each of the two opposite end-side regions of the section (or of the spring) of the connecting element, with which the connecting element is inserted into a respective groove.

According to the invention, the latching connections are each formed by a recess formed in the grooves, into which the connecting elements engage in each case with a corresponding latching projection. According to the invention, the receptacle is formed in the groove in each case in the form of an opening, that is to say a window or a recess in the groove. Such openings in the grooves are particularly easy to manufacture, for example by punching. Particularly preferred such openings each a rectangular, for example, a square cross section. A particular advantage of recordings in the form of such openings in the grooves with a respective rectangular cross-section is in particular that for such openings a corresponding latching projection on the connecting means can be formed particularly easily, via which the connecting means can be latched into the opening to form a latching connection.

According to a particularly preferred embodiment, the latching projections are provided on the connecting elements in the form of locking lugs, ie in the form of clips, which can each engage or clip into the receptacles formed in the grooves. A particular advantage of such locking projections in the form of locking lugs lies in particular in the fact that they can be formed on the connecting element particularly easily by means of injection molding. In the case of such locking lugs, the locking connection is therefore designed in the form of a so-called clip closure.

According to the invention, the connecting elements for forming a latching connection with the profile strips on opposite locking lugs, which can be latched in each case in recordings of the grooves. In other words, the connecting elements in this embodiment each have on both sides (with respect to the main surface of a particular platelet or tabular connecting element) opposite locking lugs. In this respect, the grooves can also have opposing receptacles, in particular opposite openings into which the detents engage in each case.

According to a preferred embodiment, the connecting elements have stops with which they strike against the profile strips. Each connecting element has so far at least two stops, each connecting element strikes each with at least one stop against each of the profile strips. By the connecting element is locked so far both with the profile strip and simultaneously abuts a stop against the profile strip, a solid, defined seat of the connecting elements is ensured in the profile strips, can be prevented by the slipping or displacement of the connecting elements in the profile strips. Such attacks therefore have the particular advantage that the strength, in particular the rigidity of the profile according to the invention can be further increased.

The stops on the connecting elements can be provided for example in the form of a flank or surface. To form such a flank, sections may be formed on the connecting elements which have corresponding flanks which form a stop with which the connecting element abuts against the respective profile strip. For example, these sections, on which the stops are formed, may be formed in the form of protruding sections, for example in the form of protruding ribs or protrusions. With a flank or surface of these ribs or projections, the connecting element strikes against the profile strips in the state latched to the profile strips, whereby these ribs or projections form a stop with which the connecting elements abut against the profile strips.

According to a particularly preferred embodiment, the stops each strike against the gap facing edge of the profile strips. This embodiment has the particular advantage that no special elements must be formed on the profile strips, against which strike the connecting elements with their attacks.

According to one embodiment, it is provided that the connecting elements are held in the grooves by means of frictional engagement. For this purpose, for example, be provided that the grooves - at least in sections - are formed with a slightly smaller groove width than the thickness of, as stated above, in particular in the form of a spring portions of the connecting elements, with which the connecting elements can be inserted into the grooves of the moldings , As a result, a static friction 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 latching connection, are additionally supported by means of frictional engagement in the grooves, whereby the connection of the profile strips over the connecting elements even further improved and in particular further stiffened. In this respect, it is also advantageous that the profile strips are formed of metal, since this is due to its elastic properties ideal for the formation of a frictional connection.

An essential basic idea of the profile according to the invention is also that the connecting elements are arranged at a distance from each other. Because by the connecting elements at a distance from each other are arranged, a gap or a gap between the connecting elements is formed in each case. This gap between the connecting elements favors, in particular, an optimization of the moisture balance (circulation) of an outer wall erected using the profile according to the invention. Such a circulation is particularly advantageous in the case of an outer wall which comprises components which can be adversely affected by moisture, for example condensation water. Such components may, for example, be gypsum boards or wood-based panels or insulating materials which are arranged in the free space between the building panels.

Another advantage of such spaced apart connecting elements consists in a further saving of material.

According to one embodiment, the grooves and the grooves formed in the grooves are formed uniformly along the gap. In this embodiment, the design of the grooves and the design and arrangement of the images along the gap so does not change. In particular, the recordings in this embodiment each have the same dimensions, an equal distance to the opening of the groove and an equal distance from each other. This has the advantage that for a profile according to the invention only a single type of connecting elements can be used, which can be used to connect the moldings at any point, since the moldings are designed to be uniform. Another advantage is that the strength behavior of the profile remain unchanged in such a uniform design of the moldings over the entire length of the profile, so that the profile ensures a very even load bearing over its entire length. Finally, another advantage according to the uniform profile strips is that they can be produced particularly easily manufactured.

The profile strips each have an area on which the grooves are formed. These grooves are formed along the gap separating the profile strips. The grooves may in particular be produced by metal forming. The regions of the profile strips, on each of which the grooves are formed, can preferably be facing each other and particularly preferably be formed in one plane. Particularly preferably, the grooves of both profile strips run in a common plane. This has the particular advantage that the Connecting elements in this plane can be inserted into the two grooves of the profile strips.

The profile strips can each have areas that extend at right angles from these areas where the grooves are formed away. These areas can be designed in particular for planking with building boards. For this purpose, these areas may have, for example, holes or other means to which structural panels can be screwed or fastened. These areas of the profile strips, to which the building boards may be attached, preferably extend in the same direction. Preferably, these areas may be bent by deformation of the areas where the grooves are arranged.

Of the areas where the building panels can be attached to the moldings, further areas can be connected, which extend at right angles to the areas where the building panels can be attached to the moldings, away. Preferably, these areas of the profile strips can extend toward one another and, particularly preferably, run in a common plane. These areas can serve in particular for stiffening the profile strips or the profile according to the invention. These other areas may also preferably be bent by forming from the areas where structural panels may be attached to the moldings.

The connecting elements may each have a thermal conductivity in the range from 0.1 to 5 W / mK, more preferably in the range from 0.2 to 1 W / mK and even more preferably in the range from 0.2 to 0.5 W / mK. The thermal conductivity of the connecting elements can be determined according to DIN EN ISO 22007-1: 2012-04.

The profile strips can each have a thermal conductivity in the range from 10 to 100 W / mK, for example also in the range from 20 to 80 W / mK. The thermal conductivity of the profile strips 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 may have a thermal conductivity in the range from 0.02 to 0.2 W / mK, more preferably in the range from 0.03 to 0.2 W / mK and even more preferably in the range from 0.04 to 0.1 W / mK. In particular, the profile according to the invention may have a thermal conductivity from the region at one of the profile strips, to which a building board can be attached, to the region of the other of the profile strips, to which a building board can be attached, in the aforementioned height. The thermal conductivity of the profile can be determined according to DIN 4108-2: 2013-02.

The profile 1 comprises two profiled strips 10, 20 of metallic coated structural steel. The profiled strips 10, 20 are parallel to one another and form a gap 30 between the profile strips 10, 20th spaced apart. In this case, the profile strips 10, 20 each mirror-symmetrical to a centrally through the gap 30 extending plane of symmetry (not shown) and arranged. Each of the profile strips 10, 20 each has a groove 11, 21 running along the gap 30.

The profile strips 10, 20 each have a thermal conductivity of 50 W / mK.

In order to form a further detail below explained latching connection with connecting elements 40 are in the grooves 11, 21 respectively receptacles 12, 13; 22, 23 formed in the form of rectangular openings. These recordings 12, 13; 22, 23 are each equally spaced along the gap 30 in the respective grooves 11, 21 of the profile strips 10, 20 are arranged. In this case, two opposing recesses 12, 13 and 22, 23 are respectively formed on the respective grooves 11, 12. The areas 14, 24 of the profiled strips 10, 20, on each of which the groove 11, 21 is formed facing each other and formed in a common plane, wherein the grooves 11, 21 are formed in this plane, the respective openings of the grooves 11th , 21 face each other and are also in this plane. These regions 14, 24 of the profiled strips 10, 12, on which the grooves 11, 21 are formed, are adjoined by regions 15, 25 extending at right angles from these regions 14, 24, which extend in the same direction. In these areas 15, 25 can be fixed in the construction of an outer wall using such profiles 1 structural panels (see FIG. 10 ). In turn, in each case a region 16, 26 adjoins these regions 15, 25, which in each case extends at right angles away from these regions 15, 25, wherein the latter further areas 16, 26 of the profile strips 10, 20 extend towards each other and extend in a common plane. These further regions 16, 26 are used in particular to stiffen the respective profile strips 10, 20.

To produce the profiled strips 10, 20 metallic coated sheets of structural steel by roll forming to the profile strips 10, 20 were roll formed and then the recesses 12, 13 and 22, 23 each formed by punching.

In particular FIG. 7 shows, the profile strips 10, 20 substantially a U-shaped cross-section, wherein the respective U-shaped openings of the profile strips 10, 20 facing each other.

In addition to the two profile strips 10, 20, the profile 1 comprises connecting elements 40 made of a polyamide-glass fiber composite material with a proportion of glass fibers of 50 mass%, based on the total mass of the composite material. This polyamide-glass fiber composite material of the connecting elements 40 has a substantially lower thermal conductivity than the metallic coated steel sheet of the profile strips 10, 20.

The connecting elements 40 each have a thermal conductivity of 0.27 W / mK.

The connecting elements 40 are each manufactured as a one-piece injection molded part and have a tabular basic shape with a rectangular outer contour. All connecting elements 40 are identical. The thickness d of the connecting elements 40 is 4 mm. Each connecting element 40 has two opposite sections 41, 42, which are also formed in the thickness d, wherein each of the sections 41, 42 in each case in one of the grooves 11, 21 of the profile strips 10, 20 can be inserted. The sections 41, 42 are so far each formed as a spring, which in each case enter into a tongue and groove connection with the grooves 11, 21. At the sections 41, 42, each of the connecting elements 40 at distally spaced-apart regions of the sections 41, 42 has in each case two opposite latching noses 43.1a, 43.1b; 43.2a, 43.2b; 44.1a, 44.1b; 44.2a, 44.2b. These locking lugs 43.1a, 43.1b; 43.2a, 43.2b; 44.1a, 44.1b; 44.2a, 44.2b are dimensioned and spaced from each other such that they form locking connections in the recesses 12, 13; 22, 23 engage in the grooves 11, 21, when the connecting elements 40 are inserted with their sections 41, 42 respectively in the grooves 11, 21.

By the connecting elements 40 are inserted with each of the two sections 41, 42 respectively in the grooves 11, 21 of the profile strips 10, 20, the profile strips 10, 20 are mechanically connected to each other via the connecting elements 40. At the same time, the connecting elements 40 via the locking lugs 43.1a, 43.1b; 43.2a, 43.2b; 44.1a, 44.1b; 44.2a, 44.2b with the receptacles 12, 13 formed correspondingly in the grooves for this purpose; 22, 23 latched to form a latching connection in the grooves 11, 21.

Since the connecting elements 40 have a lower thermal conductivity than the profile strips 10, 20, the profile strips 10, 20 are simultaneously thermally separated from each other by the connecting elements 40.

The connecting elements 40 are formed along the gap 30 at a distance from each other, so that between the connecting elements 40 each have a gap 50 remains.

The grooves 11, 21 each have a groove width of 4 mm in the region of the groove bottom, which corresponds to the thickness d of the sections 41, 43. This groove width decreases slightly towards the opening of the grooves 11, 21, respectively. As a result, the sections 41, 43, in addition to the latching connection as described above, additionally held by frictional engagement in the grooves 11, 21 a.

The connecting elements 40 have stops 45a, 45b; 47a, 47b, with which they strike against the moldings 10, 20 respectively. Each connecting element 40 strikes in each case with two stops 45a, 45b and 47a, 47b against each one of the profile strips 10, 20, when the respective connecting element 40 with the two profile strips 10, 20 is locked. The stops 45a, 45b, with which each connecting element 40 abuts against the profiled strip 10, are formed on two ribs 46a, 46b, which are formed on the opposing main surfaces on the connecting element 40. In this case, the stops 45a, 45b each form an edge of the respective rib 46a, 46b. Accordingly, each connecting element 40 abuts with two stops 47a, 47b on the profiled strip 20, wherein these stops 47a, 47b are formed correspondingly as flanks of ribs 48a, 48b arranged on opposite sides of the connecting element 40.
