Description

Die Erfindung betrifft ein Halteteil nach dem Oberbegriff des Anspruchs 1.The invention relates to a holding part according to the preamble of claim 1.

Zur Befestigen mindestens eines Sichtprofils an einer als Wand ausgebildeten Unterkonstruktion ist ein Halteteil aus der FR 2734589 A1 bekannt, welches ein offenes und im Querschnitt hutförmiges Profil aufweist. Dieses aus einem Metallblech durch Abkanten umgeformte Profil besitzt zwei durch einen Steg miteinander verbundene und davon rechtwinkelig abgekantete Schenkel, an die zwei Flansche je rechtwinkelig abgekantet anschließen. Im ersten Flansch des hutförmigen Profils sind Montageöffnungen zur Befestigung des Halteteils über Schrauben an der Unterkonstruktion vorgesehen - während der zweite Flansch des hutförmigen Profils auf der Unterkonstruktion lose aufliegt und an diesem Flansch ein rechtwinkelig abgekanteter Randschenkel anschließt.
Am Steg des Halteteils sind zungenförmige Abschnitte vorgesehen, welche dem Steg vorkragen und zum Eingreifen in je eine Nut an einer Seite des Sichtprofils ausgebildet sind. Die zungenförmigen Abschnitte werden durch Einschneiden und Formbiegen aus dem Steg gebildet - wobei der zungenförmige Abschnitt vom Zungengrund bis zum freien Zungenende quer zur Profilängsrichtung verläuft.
Witterungsbedingte Bewegungen der Sichtprofile - beispielsweise aufgrund von Schwinden oder Quellen -, tordieren aufgrund der Hebelwirkungen der zungenförmigen Abschnitte das Halteteil vergleichsweise stark, was plastische Verformungen am Halteteil begünstigt und damit auch die Standfestigkeit des Halteteils im Befestigen der Sichtprofile beeinträchtigt.For fastening at least one visible profile to a substructure designed as a wall, a holding part from the FR 2734589 A1 known, which has an open and hat-shaped profile in cross section. This profile, which is formed from a sheet of metal by folding, has two legs which are connected to one another by a web and bent at right angles, to which two flanges are connected, each bent at a right angle. In the first flange of the hat-shaped profile, mounting openings are provided for fastening the holding part to the substructure by means of screws - while the second flange of the hat-shaped profile rests loosely on the substructure and a right-angled edge limb connects to this flange.
On the web of the holding part, tongue-shaped sections are provided which protrude from the web and are each designed to engage in a groove on one side of the viewing profile. The tongue-shaped sections are formed by cutting and shaping from the web - the tongue-shaped section extending transversely to the longitudinal direction of the profile from the base of the tongue to the free end of the tongue.
Weather-related movements of the viewing profiles - for example due to shrinkage or swelling - twist the holding part comparatively strongly due to the leverage effects of the tongue-shaped sections, which favors plastic deformations on the holding part and thus also impairs the stability of the holding part when fastening the viewing profiles.

Die Erfindung hat sich daher die Aufgabe gestellt, ein Halteteil der eingangs geschilderten Art derart in seiner Konstruktion zu verändern, dass damit witterungsbedingte Bewegungen standfest abgefangen werden können. Zudem soll das Halteteil kostengünstig herstellbar sein.The object of the invention is therefore to change the construction of a holding part of the type described at the outset in such a way that weather-related movements can be intercepted in a stable manner. In addition, the holding part should be inexpensive to manufacture.

Die Erfindung löst die gestellte Aufgabe durch die Merkmale des Anspruchs 1.The invention solves this problem by the features of claim 1.

Weist das Halteteil am ersten und zweiten Flansch jeweils mindestens eine Montageöffnung auf, kann zunächst durch eine beidseitige Verankerung des Halteteils an der Unterkonstruktion dessen Torsionssteifigkeit deutlich erhöht werden. Verläuft zudem der federnd ausgebildete zungenförmige Abschnitt von seinem Zungengrund bis zu seinem freien Zungenende in Profilängsrichtung des Profils, belasten witterungsbedingte Bewegungen der Sichtprofile das Halteteil auf Biegung - welche Biegebelastung vom Hutprofil aufgrund der vergleichsweise hohen Biegesteifigkeit abgefangen werden können. Erfindungsgemäß sind Torsionsbelastungen auf das Halteteil sohin auf verbesserte Weise reduzierbar, womit das Halteteil frei von plastischen Verformungen gehalten werden kann. Derart ist also eine besonders standfeste Befestigung der Sichtprofile zu gewährleisten. Zudem ist ein derartiges Halteteil vergleichsweise einfach und kostengünstig herstellbar.If the holding part on the first and second flange each has at least one assembly opening, an anchoring of the holding part to the substructure on both sides can first significantly increase its torsional rigidity. If the resilient tongue-shaped section extends from the base of the tongue to the free end of the tongue in the profile longitudinal direction of the profile, weather-related movements of the visible profiles put strain on the holding part due to bending - which bending load can be absorbed by the hat profile due to the comparatively high bending stiffness. According to the invention, torsional loads on the holding part can be reduced in an improved manner, so that the holding part can be kept free from plastic deformations. In this way, a particularly stable attachment of the visible profiles is to be guaranteed. In addition, such a holding part is comparatively simple and inexpensive to manufacture.

Begrenzen der erste und zweite Flansch das Profil, kann sich ein in seiner Konstruktion weiter vereinfachtes und kostengünstig herzustellendes Halteteils ergeben.If the first and second flange limit the profile, a holding part that is further simplified in its construction and can be produced inexpensively can result.

Ein symmetrisch zu seiner Mittelebene ausgebildetes Halteteil kann geschaffen werden, wenn die Schenkel vom Steg rechtwinklig abgekantet und die Flansche vom jeweiligen Schenkel rechtwinklig abgekantet sind. Diese symmetrische Gestalt des Halteteils kann unter anderem auch dessen Handhabung bei der Montage der Sichtprofile erleichtern.A holding part formed symmetrically to its central plane can be created if the legs are bent at a right angle from the web and the flanges are bent at right angles from the respective leg. This symmetrical shape of the holding part can, among other things, also facilitate its handling when assembling the viewing profiles.

Eine sichere Montage des Halteteils kann ermöglicht werden, wenn die Montageöffnungen an gegenüberliegenden stirnseitigen Enden der Flansche angeordnet sind. Des Weiteren kann solch eine Montage die Torsionssteifigkeit des Halteteils unterstützen, was die Zuverlässigkeit des Halteteils in der Befestigung des Sichtprofils weiter erhöhen kann.Secure mounting of the holding part can be made possible if the mounting openings are arranged at opposite ends of the flanges. Furthermore, such an assembly can support the torsional rigidity of the holding part, which can further increase the reliability of the holding part in the fastening of the visible profile.

Die Handhabung des Halteteils zum Befestigen des Sichtprofils kann weiter erleichtert werden, wenn der zungenförmige Abschnitt an seinem freien Ende einen Einführschenkel ausbildet, welcher vom Steg weg geneigt verläuft.The handling of the holding part for attaching the visible profile can be further facilitated if the tongue-shaped section forms an insertion leg at its free end, which extends inclined away from the web.

Maßtoleranzen am Sichtprofil, insbesondere dessen Nut, können vorteilhaft ausgeglichen werden, wenn am Einführschenkel auf der dem Steg zugewandten Schenkelseite eine eingeprägte Ausbuchtung vorkragt. Solch eine erfindungsgemäße Ausbuchtung erhöht nämlich die Stärke des Einführschenkels - und kann so beispielsweise Maßungenauigkeiten in der Tiefe der Nut am Sichtprofil ausgleichen bzw. die Haltekraft des Halteteils verbessern. Ein in seiner Funktion besonders sicheres Halteteil ist derart geschaffen.Dimensional tolerances on the visible profile, in particular its groove, can advantageously be compensated for if an embossed bulge protrudes on the insertion leg on the side of the leg facing the web. Such a bulge according to the invention increases the strength of the insertion leg - and can thus, for example, compensate for inaccuracies in the depth of the groove on the visible profile or improve the holding force of the holding part. A holding part that is particularly safe in its function is created in this way.

Die Klemmwirkung des zungenförmigen Abschnitts in der Nut des Sichtprofils kann weiter erhöht werden, wenn an den Einführschenkeln ein Anschlussschenkel mit einer gegenüber dem Einführschenkel geringeren Neigung anschließt. Außerdem kann so ein federnder Effekt verbessert werden - und dennoch eine einfache Montage zulassen.The clamping effect of the tongue-shaped section in the groove of the visible profile can be increased further if a connecting leg with a lower inclination than the insertion leg connects to the insertion legs. In addition, a resilient effect can be improved in this way - and still allow easy assembly.

Kragen zwei durch Einschneiden und Formbiegen aus dem Steg gebildete zungenförmige Abschnitte dem Steg vor, wobei die entgegengesetzt gerichtet verlaufenden Abschnitte zum Eingreifen in je eine Nut eines anderen Sichtprofils ausgebildet sind, kann das Halteteil zur Befestigung von zwei aneinander angrenzenden Sichtprofilen verwendet werden - und dabei die genannten Vorteile zur Geltung bringen.If two tongue-shaped sections are formed in front of the web by cutting and shaping from the web, the oppositely directed sections being designed to engage in a groove of a different viewing profile, the holding part can be used to fasten two adjacent viewing profiles - and thereby the bring the advantages mentioned.

Die Steifigkeit des Halteteils kann weiter verbessert werden, indem mindestens eine Kante zwischen Steg und Schenkel oder zwischen Schenkel und Flansch eine sich auf diesen Bereich der Kante beschränkende Sicke als Kantenversteifung aufweist. Eine derartige Kantenversteifung kann beispielsweise durch Einprägen in die Kante geschaffen werden.The rigidity of the holding part can be further improved if at least one edge between the web and the leg or between the leg and the flange has a bead, which is limited to this area of the edge, as an edge reinforcement. Such an edge stiffening can be created, for example, by stamping it into the edge.

Weisen die ersten Kanten zwischen Steg und Schenkel je zwei erste Sicken und die zweiten Kanten zwischen Schenkeln und Flanschen je eine zweite Sicke auf, wobei die zweiten Sicken zwischen, insbesondere mittig zu, den ersten Sicken angeordnet sind, kann am Halteteil ein Optimum im Verhältnis Konstruktionsaufwand zu Steifigkeit gegenüber Verformung erreicht werden.If the first edges between the web and the legs each have two first beads and the second edges between the legs and flanges each have a second bead, the second beads being arranged between the first beads, in particular in the middle, an optimum can be achieved on the holding part in relation to the design effort to achieve rigidity against deformation.

Bildet der Steg eine Auflagefläche für das Sichtprofil aus, kann das Sichtprofil auf einfache Weise standfest von der Unterkonstruktion beabstandet vor kontaktbedingten Witterungseinflüssen geschützt werden.If the web forms a support surface for the view profile, the view profile can be protected in a simple manner, at a stable distance from the substructure, from contact-related weather influences.

Das erfindungsgemäße Halteteil kann sich insbesondere für ein Terrassensystem mit mindestens einem Sichtprofil und mit einer Unterkonstruktion eignen, an die das Halteteil befestigt ist, wobei der zungenförmige Abschnitt des Halteteils in eine Nut an einer Seite des Sichtprofils eingreift.The holding part according to the invention can be suitable in particular for a terrace system with at least one visible profile and with a substructure to which the holding part is fastened, the tongue-shaped section of the holding part engaging in a groove on one side of the visible profile.

Besonders vorteilhaft liegt bei solch einem Terrassensystem das Sichtprofil auf dem Steg des Halteteils auf, um die Sichtprofile einfach und standfest von der Unterkonstruktion zu beabstanden bzw. vor Nässe etc. zu schützen.In such a terrace system, the view profile lies particularly advantageously on the web of the holding part in order to easily and steadily space the view profiles from the substructure or to protect them from moisture, etc.

Bevorzugt liegt das Sichtprofil auf dem Steg des Halteteils auf.The view profile preferably lies on the web of the holding part.

Nach Fig. 1 wird in einer Ansicht des Terrassensystems 1 beispielsweise dargestellt, bei welchem mit Hilfe eines Halteteils 2 zwei als Terrassenprofile ausgeführte Sichtprofile 3, 4 an eine Unterkonstruktion 5 geklemmt und damit an dieser Unterkonstruktion 5 befestigt werden. Die Sichtprofile 3, 4 weisen vorzugsweise ein Vollprofil insbesondere aus einem Holz-Kunststoff-Verbundwerkstoffe (WPC) auf und sind vorzugsweise als Dielen ausgebildet.To Fig. 1 is shown in a view of the terrace system 1, for example, in which, with the aid of a holding part 2, two view profiles 3, 4 designed as terrace profiles are clamped to a substructure 5 and are thus fastened to this substructure 5. The viewing profiles 3, 4 preferably have a full profile in particular from a wood-plastic composite (WPC) and are preferably designed as planks.

Das Halteteil 2 wird aus einem Metallblech, insbesondere Stahlblech, vorzugsweise Edelstahlblech, geformt. Hierzu wird das Metallblech zu einem offenen und im Querschnitt hutförmigen Profil 6 umgeformt - vorzugsweise durch Abkanten. Das hutförmige Profil 6 umfasst zwei durch einen Steg 7 miteinander verbundene Schenkel 8.1, 8.2, an welche Schenkel 8.1, 8.2 je ein Flansch 9.1, 9.2 anschließt - wie in Fig. 2 erkennbar.The holding part 2 is formed from a metal sheet, in particular steel sheet, preferably stainless steel sheet. For this purpose, the metal sheet is formed into an open and hat-shaped profile 6 in cross section - preferably by folding. The hat-shaped profile 6 comprises two legs 8.1, 8.2 connected to one another by a web 7, to which legs 8.1, 8.2 each a flange 9.1, 9.2 connects - as in FIG Fig. 2 recognizable.

Das Halteteil 2 weist am Steg 7 zwei zungenförmige Abschnitte 10, 11 auf, die dem Steg 7 vorkragen, entgegengesetzt gerichtet verlaufen und aus dem Metallblech des Stegs 7 durch Einschneiden und Formbiegen gebildet werden. Im Allgemeinen wird erwähnt, dass es auch vorstellbar ist, dass das Halteteil 2 nur einen oder auch mehr als zwei solcher zungenförmigen Abschnitte 10, 11 aufweist - was in den Figuren allerdings nicht gesondert dargestellt ist.The holding part 2 has on the web 7 two tongue-shaped sections 10, 11 which protrude from the web 7, run in opposite directions and are formed from the metal sheet of the web 7 by cutting and shaping. In general, it is mentioned that it is also conceivable for the holding part 2 to have only one or even more than two such tongue-shaped sections 10, 11 - which, however, is not shown separately in the figures.

Die zungenförmige Abschnitte 10, 11 sind zum Eingreifen in je eine Nut 3.1, 4.1 an gegenüberliegenden Seiten 3.2, 4.2, insbesondere Längsseiten, der Sichtprofile 3, 4 ausgebildet. Die Sichtprofile 3, 4 liegen auf dem Steg 7 des Halteteils 2 auf, der hierfür Auflageflächen 7.3, 7.4 ausbildet. In Zusammenwirken mit den zungenförmigen Abschnitten 10, 11 werden sohin die Sichtprofil 3, 4 am Halteteil 2 befestigt. Im Allgemeinen wird erwähnt, dass der zungenförmige Abschnitt 10, 11 bzw. die zungenförmigen Abschnitte 10, 11 federnd ausgebildet sind. Auf diese Weise kann einer witterungsbedingten Bewegung und/oder Formänderung der Sichtprofile 3, 4 gefolgt werden, was die Standfestigkeit verbessert.The tongue-shaped sections 10, 11 are each designed to engage in a groove 3.1, 4.1 on opposite sides 3.2, 4.2, in particular long sides, of the viewing profiles 3, 4. The viewing profiles 3, 4 rest on the web 7 of the holding part 2, which forms support surfaces 7.3, 7.4 for this. In cooperation with the tongue-shaped sections 10, 11, the viewing profiles 3, 4 are attached to the holding part 2. In general, it is mentioned that the tongue-shaped section 10, 11 or the tongue-shaped sections 10, 11 are resilient. In this way, a weather-related movement and / or change in shape of the viewing profiles 3, 4 can be followed, which improves the stability.

Das Halteteil 2 wird mit einem als Holzschraube 12.1, 12.2 mit Zylinderkopf ausgeführtem Befestigungsmittel 12 an der Unterkonstruktion 5 befestigt. Hierzu durchgreift das Befestigungsmittel 12 eine Montageöffnung 13.1, 13.2 am Halteteil 2, welche Montageöffnung 13.1, 13.2 an einem Flansch 9.1, 9.2 vorgesehen ist. Erfindungsgemäß weist das Halteteil 2 am ersten Flansch 9.1 und auch am zweiten Flansch 9.2 je eine Montageöffnung 13.1, 13.2 auf. Das Halteteil 2 wird sohin über zwei Holzschrauben 12.1, 12.2 mit der Unterkonstruktion 5 verbunden - was die Torsionssteifigkeit des offenen Profils 6 erheblich erhöht. Diese beiden Montageöffnungen 13.1, 13.2 sind am ersten und zweiten Flansch 9.1, 9.2 an gegenüberliegenden stirnseitigen Flanschenden 9.3, 9.4 vorgesehen.The holding part 2 is fastened to the substructure 5 with a fastening means 12 designed as a wood screw 12.1, 12.2 with a cylinder head. For this purpose, the fastening means 12 passes through an assembly opening 13.1, 13.2 on the holding part 2, which assembly opening 13.1, 13.2 is provided on a flange 9.1, 9.2. According to the invention, the holding part 2 has a mounting opening 13.1, 13.2 on the first flange 9.1 and also on the second flange 9.2. The holding part 2 is connected to the substructure 5 by means of two wood screws 12.1, 12.2 - which increases the torsional rigidity of the open profile 6 considerably. These two mounting openings 13.1, 13.2 are provided on the first and second flange 9.1, 9.2 on opposite end flange ends 9.3, 9.4.

Zudem verlaufen die zungenförmigen Abschnitte 10, 11 von ihrem Zungengrund 10.1, 11.1 bis zu ihrem freien Zungenende 10.2, 11.2 in Profilängsrichtung 14 - wodurch die mechanischen Belastungen auf die zungenförmigen Abschnitte 10, 11 in erster Linie das Halteteil 2 auf Biegung - also vermindert auf Torsion - belasten. Da das im Querschnitt hutförmige Profil 6 eine vergleichsweise hohe Torsionssteifigkeit aufweist, ist das erfindungsgemäße Halteteil 2 gegenüber plastischen Verformungen folglich besonders robust.In addition, the tongue-shaped sections 10, 11 run from their tongue base 10.1, 11.1 to their free tongue end 10.2, 11.2 in the longitudinal direction 14 of the profile - as a result of which the mechanical stresses on the tongue-shaped sections 10, 11 primarily hold the holding part 2 on bending - that is, on torsion - strain. Since the hat-shaped profile 6 has a comparatively high torsional rigidity, the holding part 2 according to the invention is consequently particularly robust with respect to plastic deformations.

Die ersten und zweiten Schenkel 8.1, 8.2 sind vom Steg 7 rechtwinklig abgekantet. Zudem ist der erste Flansch 9.1 vom ersten Schenkel 8.1 und der zweite Flansch 9.2 vom zweiten Schenkel 8.2 rechtwinkelig abgekantet. Das Profil 6 wird vom ersten Flansch 9.1 und zweiten Flansch 9.2 begrenzt, was ein einfach herzustellendes und mechanisch besonders hoch belastbares Profil 6 ergibt. Das Profil 6 ist sohin als Hutprofil ausgebildet.The first and second legs 8.1, 8.2 are bent at right angles from the web 7. In addition, the first flange 9.1 from the first leg 8.1 and the second flange 9.2 from the second leg 8.2 are folded at right angles. The profile 6 is delimited by the first flange 9.1 and the second flange 9.2, which results in a profile 6 which is easy to manufacture and mechanically particularly resilient. The profile 6 is thus designed as a hat profile.

Die Kanten 15.1, 15.2, 16.1, 16.2, welche sich durch die Abkantung zwischen dem Steg 7 und den Schenkeln 8.1, 8.2 und auch zwischen den Schenkeln 8.1, 8.2 und den Flanschen 9.1, 9.2 ergeben, weisen eine Kantenversteifung 17 auf. Diese Kantenversteifung 17 wird durch eine sich auf diesen Bereich der Kanten 15.1, 15.2, 16.1, 16.2 beschränkende und dort eingeprägte Sicke 18, 19 geschaffen. Die ersten Kanten 15.1, 15.2 zwischen dem Steg 7 und den Schenkeln 8.1, 8.2 weisen je zwei erste Sicken 18 auf. Die zweiten Kanten 16.1, 16.2 zwischen den Schenkeln 8.1, 8.2 und den Flanschen 9.1, 9.2 weisen je eine zweite Sicke 19 auf. Die zweite Sicke 19 ist mittig zwischen den beiden anderen ersten Sicken 18 angeordnet, was das Profil 6 des Halteteils 2 mechanisch besonders gut versteift.The edges 15.1, 15.2, 16.1, 16.2, which result from the fold between the web 7 and the legs 8.1, 8.2 and also between the legs 8.1, 8.2 and the flanges 9.1, 9.2, have an edge stiffening 17. This edge reinforcement 17 is created by a bead 18, 19 which is limited to this area of the edges 15.1, 15.2, 16.1, 16.2 and is stamped there. The first edges 15.1, 15.2 between the web 7 and the legs 8.1, 8.2 each have two first beads 18. The second edges 16.1, 16.2 between the legs 8.1, 8.2 and the flanges 9.1, 9.2 each have a second bead 19. The second bead 19 is arranged in the middle between the two other first beads 18, which mechanically stiffens the profile 6 of the holding part 2 particularly well.

Beide zungenförmigen Abschnitte 10, 11 bilden an ihrem freien Ende 10.1, 11.2 je einen Einführschenkel 10.3, 11.3 aus, welcher vom Steg 7 weg geneigt verläuft. An diesen Einführschenkeln 10.3, 11.3 schließt jeweils ein Anschlussschenkel 10.4, 11.4 mit einer gegenüber dem jeweiligen Einführschenkel 10.3, 11.3 geringeren Neigung an. Dieses Abwinkeln der zungenförmige Abschnitte 10, 11 verbessert die federnde Klemmwirkung mit den Sichtprofilen 3, 4 und erleichtert deren Montage am Halteteil.Both tongue-shaped sections 10, 11 each form an insertion leg 10.3, 11.3 at their free end 10.1, 11.2, which extends inclined away from the web 7. A connecting leg 10.4, 11.4 with a lower inclination than the respective insertion leg 10.3, 11.3 connects to these insertion legs 10.3, 11.3. This angling of the tongue-shaped sections 10, 11 improves the resilient clamping action with the viewing profiles 3, 4 and facilitates their assembly on the holding part.

Die Einführschenkel 10.3, 11.3 weisen zudem an der dem Steg 7 zugewandten Schenkelseiten je eine vorkragende Ausbuchtung 20 auf. Diese Ausbuchtungen 20 werden in den Einführschenkel 10.3, 11.3 eingeprägt. Damit sind Maßtoleranzen an den betreffenden Nuten 3.1, 3.2 der Sichtprofile 3, 4 ausgleichbar - was die Standfestigkeit des Halteteils 2 weiter verbessert.The insertion legs 10.3, 11.3 also each have a projecting bulge 20 on the leg sides facing the web 7. These bulges 20 are impressed into the insertion legs 10.3, 11.3. Dimensional tolerances on the relevant grooves 3.1, 3.2 of the viewing profiles 3, 4 can thus be compensated for - which further improves the stability of the holding part 2.
