Description

TECHNISCHER HINTERGRUNDTECHNICAL BACKGROUND

Bei modernen Gebäudehüllen werden heute für den Wandaufbau eine Vielzahl von Materialien verwendet, die auf ihre Wärmedämmeigenschaften optimiert wurden. Darunter fallen Lochziegel, Porenbeton und andere Baustoffe. Sehr oft wird der Ton zur Ziegelherstellung mit Porosierungsstoffen bzw. Ausbrennstoffen wie Polystyrol, Papier oder Holzfasern vermischt, die nach dem Brennen Poren hinterlassen Bei Hochlochziegeln mit vertikal angeordneten Kammern ist die tragende Funktion bei vertikaler Druckbelastung gewährleistet. Es ist jedoch schwierig, Zugbelastungen in den Ziegel abzuleiten abzutragen, weil die Stege zwischen den Kammern dünn sind und zudem wegen der Poren brüchig. Für Fenster und Türen, die in Wandöffnungen aus solchen Materialien verankert werden müssen, müssen daher besondere Massnahmen getroffen werden, insbesondere wenn eine absturzsichernde Befestigung erreicht werden soll.In modern building envelopes, a large number of materials that have been optimized for their thermal insulation properties are used for the wall structure. This includes perforated bricks, aerated concrete and other building materials. Very often, the clay for brick production is mixed with porosity or burnout materials such as polystyrene, paper or wood fibers, which leave pores after firing. Perforated bricks with vertically arranged chambers guarantee the load-bearing function under vertical pressure loads. However, it is difficult to dissipate tensile loads in the brick because the webs between the chambers are thin and, moreover, brittle because of the pores. For windows and doors that have to be anchored in wall openings made of such materials, special measures must therefore be taken, especially if a fall-proof fastening is to be achieved.

STAND DER TECHNIKSTATE OF THE ART

Die DE 2013 11 513U beschreibt eine Vorrichtung zum Abstützen und Befestigen von Fenster- und Türrahmen. Sie umfasst einerseits eine biegesteifen Profilschiene, die mit dem Rahmen verbunden wird und andererseits ein Verstellelement aufweist, welches die Justage des Fenster/Türrahmens relativ zur Wandöffnung erlaubt. Die Profilschiene muss hierzu an der Brüstung, der Laibung oder gegebenenfalls am Sturz befestigt werden, was aus den oben genannten Gründen problematisch sein kann. Deshalb beschreibt dieser Stand der Technik eine ergänzende Halteschiene, die als Winkel geformt formschlüssig in die Profilschiene eingeschoben wird, sodass der erste Schenkel parallel zur Brüstung / Laibung liegt und der zweite Schenkel an der Gebäudeinnenseite des Wandelements befestigt werden kann. Durch Verschrauben der Halteschiene mit der Profilschiene können deren Lasten an einer zusätzlichen, von der Brüstung beabstandeten Stelle der Wand eingeleitet werden.The DE 2013 11 513U describes a device for supporting and securing window and door frames. On the one hand, it comprises a rigid profile rail which is connected to the frame and, on the other hand, has an adjusting element which allows the window / door frame to be adjusted relative to the wall opening. For this purpose, the profile rail must be attached to the parapet, the reveal or, if necessary, to the lintel, which can be problematic for the reasons mentioned above. Therefore, this prior art describes a supplementary support rail that is shaped as an angle and pushed positively into the profile rail so that the first leg lies parallel to the parapet / soffit and the second leg can be attached to the inside of the building of the wall element. By screwing the retaining rail to the profile rail, its loads can be introduced at an additional point on the wall that is spaced from the parapet.

Mit zunehmender Grösse der Fenster- und Türrahmen, aufgrund des höheren Gewichts der Mehrfachverglasung und aufgrund gestiegener Sicherheitsvorschriften sind solche Massnahmen nicht mehr ausreichend.With the increasing size of the window and door frames, due to the higher weight of the multiple glazing and increased safety regulations, such measures are no longer sufficient.

Es besteht daher das Bedürfnis, das bestehende System soweit zu verbessern, dass auch Fenster- und Türrahmen hohen Gewichts in Öffnungen hoch wärmedämmender Wandaufbauten sicher eingesetzt werden können. Als Randbedingung ist dabei die Kompatibilität mit bestehenden Systemen erforderlich, insbesondere mit Profilschienensystemen des Standes der Technik.There is therefore a need to improve the existing system to such an extent that heavy weight window and door frames can also be safely used in openings in highly insulating wall structures. Compatibility with existing systems is required as a boundary condition, in particular with profile rail systems of the prior art.

BESCHREIBUNG DER ERFINDUNGDESCRIPTION OF THE INVENTION

Diese Aufgabe wird erfüllt durch die Verwendung einer Klemme, die vorwiegend im Bereich der Laibung eingesetzt wird, jedoch bei Bedarf auch am Sturz oder an der Brüstung eingesetzt werden kann. Unter Klemme wird dabei ein Spannmittel verstanden, bei dem im Gegensatz zu einer Klammer zur Klemmung nicht vorrangig federnden Elemente eingesetzt werden. Bei der Klemme gemäss vorliegender Erfindung wird das oder die zu klemmenden Elemente zwischen zwei Schenkeln geklemmt, die wiederum durch ein Verbindungselement verbunden sind.This task is achieved by using a clamp, which is mainly used in the area of the reveal, but can also be used on the lintel or on the parapet if necessary. A clamp is understood to mean a clamping means in which, in contrast to a clamp, resilient elements are not primarily used for clamping. In the clamp according to the present invention, the element or elements to be clamped is clamped between two legs, which in turn are connected by a connecting element.

Die besagte Klemme dient als Befestigungsbasis für ein Fenster- oder Türelement in einer Wandöffnung, wobei die Klemme einen ersten und einen zweiten Schenkel und ein Verbindungselement dazwischen umfasst. Mit Befestigungsbasis ist dabei gemeint, dass an der Klemme weitere Bauelemente befestigt werden können. Dabei werden:

  • die Länge W des Verbindungselementes (also die Distanz zwischen den Verbindungspunkten mit den Schenkeln entlang des Verbindungselementes so ausgelegt ist, dass sie der Stärke D einer Wand im Bereich der Laibung, Brüstung oder des Sturzes im Wesentlichen entspricht. Getreu der Verwendung als Befestigungsbasis umklammert die Klemme also einen Wandabschnitt im Bereich einer Fensteröffnung.
  • die Winkel α zwischen dem ersten Schenkel und dem Verbindungselement sowie der Winkel β zwischen dem zweiten Schenkel und dem Verbindungselement im Wesentlichen 90° betragen und der erste und zweite Schenkel somit zueinander im Wesentlichen parallel verlaufen. Bei einer regulären Wandöffnung wo die Ebene der Laibung auf der Gebäudeaussen- wie Innenseite rechtwinklig steht, ist diese Ausbildung bevorzugt. Natürlich können durch Anpassung der Winkel äquivalent auch andere Wandgeometrien abgedeckt werden.
  • die der Öffnung angrenzenden Wandregionen einerseits als erste Seite oder Vorderseite, andererseits eine zweite oder Rückseite bezeichnet. Die der (Wand-)Öffnung zugewandten Wandabschnitte aus Brüstung, Laibung und Sturz werden als Innenseite bezeichnet.
Gemäss der erfinderischen Verwendung werden der erste Schenkel an der Vorderseite (der Wand bzw. des Wandabschnitts) und der zweite Schenkel an der Rückseite (der Wand bzw. des Wandabschnitts) befestigt, wobei das Verbindungselement an der Innenseite anliegt. Mit Anliegen ist dabei gemeint, dass das Verbindungselement in (bevorzugt voll- oder zumindest teil-)flächigem Kontakt mit der Innenseite der Wandöffnung steht, sich mit anderen Worten anschmiegt oder nur wenige Millimeter beabstandet von der Innenfläche angebracht wird. Die beiden Schenkel können in derselben Art an den Wandoberflächen (Vorderseite, Rückseite) anliegend angebracht werden.Said clamp serves as a mounting base for a window or door element in a wall opening, the clamp comprising a first and a second leg and a connecting element therebetween. The term “fastening base” means that further components can be fastened to the clamp. Thereby:
  • the length W of the connecting element (i.e. the distance between the connection points with the legs along the connecting element is designed so that it essentially corresponds to the thickness D of a wall in the area of the reveal, parapet or lintel. True to its use as a mounting base, the clamp clasps i.e. a wall section in the area of a window opening.
  • the angle α between the first leg and the connecting element and the angle β between the second leg and the connecting element are essentially 90 ° and the first and second legs thus run essentially parallel to one another. In the case of a regular wall opening where the plane of the reveal is at right angles on the outside and inside of the building, this design is preferred. Of course, by adapting the angles, other wall geometries can also be covered.
  • the wall regions adjoining the opening are referred to on the one hand as the first side or front side and on the other as a second or rear side. The wall sections facing the (wall) opening made up of the parapet, reveal and lintel are referred to as the inside.
According to the inventive use, the first leg is attached to the front (the wall or the wall section) and the second leg to the rear (the wall or the wall section), with the connecting element resting against the inside. By concern is meant that the connecting element is in (preferably full or at least partial) areal contact with the inside of the wall opening, in other words it hugs or is attached only a few millimeters away from the inner surface. The two legs can be attached to the wall surfaces (front, back) in the same way.

Wenn aufgrund der baulichen Situation die Weite W des Verbindungselementes der einzusetzenden Klemme deutlich grösser als die Wandstärke D sein sollte, kann ein Schenkel auch mit Hilfe von Abstandselementen (Klötze) an die Situation angepasst werden, die Abstandselemente werden zwischen Wandoberfläche und Schenkel angeordnet.If, due to the structural situation, the width W of the connecting element of the clamp to be used should be significantly larger than the wall thickness D, a leg can also be adapted to the situation with the help of spacer elements (blocks); the spacer elements are arranged between the wall surface and the leg.

Mit Blick auf die übliche Bausituation wird also ein Schenkel der Klemme beispielsweise an der Aussenseite eines Gebäudes verankert und der andere Schenkel an der Innenseite; das Verbindungselement liegt an der Laibung an. Die Anbringung kann dabei mit allen zulässigen Mitteln nach dem Stand der Technik geschehen, bevorzugt durch Verschraubung mit der Wand (Schrauben, Bolzen, dübellose Schraubanker, Klemmanker, Schrauben mit Dübel). Um dies zu erleichtern können die Schenkel Durchbohrungen aufweisen, durch die Befestiger in der Wand verankert werden können. Um die Lastableitung optimal zu gestalten wird die Verankerung des Schenkels an seinem Längsende (am öffnungsfernen Ende bzw. dem Längsende, das am weitesten vom Verbindungselement entfernt liegt) erfolgen.With a view to the usual construction situation, one leg of the clamp is anchored, for example, on the outside of a building and the other leg on the inside; the connecting element rests against the reveal. The attachment can be done with all permissible means according to the state of the art, preferably by screwing to the wall (screws, bolts, screw anchors without dowels, clamp anchors, screws with dowels). To facilitate this, the legs can have through-holes through which fasteners can be anchored in the wall. In order to optimally design the load dissipation, the leg is anchored at its longitudinal end (at the end remote from the opening or the longitudinal end that is furthest away from the connecting element).

Die Verwendung einer solchen Klemme erscheint auf den ersten Blick unorthodox, weil dadurch von der Aussenseite zur Innenseite eine Wärmeleitung erfolgen kann. Wärmebrücken gilt es jedoch im Bauwesen zu vermeiden. Überraschenderweise hat sich anhand von Messungen gezeigt, dass die Wärmeleitung durch eine solche Klemme geringer ist als vom Fachmann angenommen. Insbesondere bei grossflächigen Fenster- und Türelementen fällt der zusätzliche Wärmeverlust nicht ins Gewicht. Zudem wird die Klemme, besonders bei aussenisolierten Gebäuden, unter der Isolationsschicht angeordnet, was verhindert, dass die Temperaturdifferenz zwischen dem warmen und dem kalten Ende zu gross wird, was wiederum den Wärmestrom reduziert. Montageseitig ist es ein Vorteil, dass diese Klemmen eine sehr einfache und doch flexible Befestigungsbasis bieten, die sich zudem ohne weiteres mit bestehenden Befestigungssystemen kombinieren lässt.The use of such a clamp seems unorthodox at first, because it allows heat to be conducted from the outside to the inside. However, it is important to avoid thermal bridges in construction. Surprisingly, measurements have shown that the heat conduction through such a clamp is less than assumed by the person skilled in the art. In particular with large window and door elements, the additional heat loss is negligible. In addition, especially in buildings with external insulation, the clamp is placed under the insulation layer, which prevents the temperature difference between the warm and cold end from becoming too great, which in turn reduces the heat flow. On the assembly side, it is an advantage that these clamps offer a very simple yet flexible mounting base, which can also be easily combined with existing mounting systems.

Besonders bevorzugt werden die Schenkel mit unterschiedlicher Länge L1 und L2 ausgeführt (L1 ungleich L2)). Dies bietet insbesondere bei dünnen und porösen Ziegelwänden den Vorteil, dass die Lastableitung von den Schenkelenden in die Wand an zwei verschiedenen Wandabschnitten, nicht exakt gegenüber liegend, erfolgt. Eine bevorzugte Anordnung der Klemme erfolgt so, dass der kürzere der beiden Schenkel an der Rückseite der Wand (aussen) erfolgt. Allerdings kann diese Anordnung auch umgekehrt erfolgen, falls z.B. ein längerer Schenkel im Innenbereich schwieriger zu kaschieren wäre.The legs are particularly preferably designed with different lengths L1 and L2 (L1 not equal to L2). In particular with thin and porous brick walls, this offers the advantage that the load is transferred from the leg ends into the wall on two different wall sections, not exactly opposite one another. A preferred arrangement of the clamp is such that the shorter of the two legs is on the back of the wall (outside). However, this arrangement can also be reversed if, for example, a longer leg would be more difficult to conceal in the interior.

Bevorzugt werden die Schenkel und das Verbindungselement der Klemme als im Wesentlichen gerade, flache Metallelemente ausgebildet. Bevorzugtes Material wäre daher Stahl, der in die beschriebene Form gestanzt und gebogen werden kann. Eine Oberflächenbehandlung durch Verzinken, Lackieren oder Ähnliches kann vorgesehen werden. Ganz besonders bevorzugt wird die Klemme mit ihren Schenkeln und dem Verbindungselement einstückig geformt. Zu Verbesserung der Steifigkeit können am Verbindungselement eine oder mehrere, längsverlaufende Sicken vorgesehen werden, die die Lastableitfähigkeit der Klemme weiter erhöhen.The legs and the connecting element of the clamp are preferably designed as essentially straight, flat metal elements. The preferred material would therefore be steel, which can be punched and bent into the shape described. A surface treatment by galvanizing, painting or the like can be provided. Most preferably, the clamp is molded in one piece with its legs and the connecting element. To improve the rigidity, one or more longitudinal beads can be provided on the connecting element, which further increase the load-dissipating capacity of the clamp.

Gemäss einem erfinderischen Vorgehen werden die Klemmen an der Gebäudeöffnung angebracht, bevor die Fenster- bzw. Türelemente eingehoben werden. Die exakte Position kann planerisch vorgegeben oder markiert werden bzw. mit Lehren vorgegeben werden. Dann werden die Fenster- bzw. Türelemente eingehoben und können auf verschiedene Art und Weise befestigt werden. Zum einen kann die Verbindung mittels Schrauben, Bolzen oder Stiften realisiert werden. Solche Abstandsmontageschrauben werden durch den Rahmen des Tür/Fensterelementes eingedreht und schneiden sich dann selbst in das Material des Verbindungselementes ein. Alternativ oder ergänzend kann eine Justagevorrichtung mit der Klemme verbunden werden, wobei die Justagevorrichtung ein Verstellelement umfasst, das eine Lageänderung des Fenster- oder Türrahmens in der Ebene der Wand erlaubt. Solche Justageelemente sind beispielsweise die in der DE 2013 11 513U Beschriebenen. Neben der Justierbarkeit in der Ebene kann auch eine Justagemöglichkeit parallel zur Ebene vorgesehen werden mit einem Verstellelement wie im Stand der Technik bekannt.According to an inventive procedure, the clamps are attached to the building opening before the window or door elements are lifted into place. The exact position can be specified or marked in the planning or specified with gauges. Then the window or door elements are lifted in and can be attached in various ways. On the one hand, the connection can be realized using screws, bolts or pins. Such spacer mounting screws are screwed in through the frame of the door / window element and then cut themselves into the material of the connecting element. As an alternative or in addition, an adjustment device can be connected to the clamp, the adjustment device comprising an adjustment element which allows a change in the position of the window or door frame in the plane of the wall. Such adjustment elements are, for example, those in DE 2013 11 513U Described. In addition to the adjustability in the plane, an adjustment possibility parallel to the plane can also be provided with an adjustment element as known in the prior art.

Alternativ können die Klemmen nur lose an der Laibung angelegt werden, danach wird das Fenster eingehoben und in der Höhe (relativ zur Wandöffnung) justiert. Da üblicherweise die Verankerungspunkte der Fenster/Türrahmen ab Werk vorgebohrt sind, kann nun die lose eingelegte Klemme auf die notwendige Höhe angehoben und wie vorgesehen an der Wand befestigt werden. Danach erfolgt die Verbindung von Rahmen und Klemme, wir vorbeschrieben entweder direkt durch einen Befestiger oder über weitere Justageelemente gemäss Stand der Technik.Alternatively, the clamps can only be placed loosely on the reveal, after which the window is lifted in and adjusted in height (relative to the wall opening). Since the anchoring points of the window / door frames are usually pre-drilled at the factory, the loosely inserted clamp can now be raised to the required height and attached to the wall as intended. The frame and clamp are then connected, as described above, either directly using a fastener or using further adjustment elements according to the state of the art.

Die Verwendung einer Klemme kann alternativ als Verfahren zur Montage eines Fenster- oder Türelement in einer Wandöffnung beschrieben werden, wobei eine Klemme als Befestigungsbasis zum Einsatz kommt, die als wesentliche Elemente einen ersten Schenkel, einen zweiten Schenkel und ein Verbindungselement dazwischen umfasst. Die Länge W des Verbindungselementes wird so gewählt (bzw. vorgefertigt), dass sie der Stärke D der Wand entspricht, an der die Klemme angebracht werden soll (im Bereich der Laibung, Brüstung oder des Sturzes). Der Winkel α zwischen erstem Schenkel und dem Verbindungselement sowie der Winkel β zwischen dem zweiten Schenkel und dem Verbindungselement werden im Wesentlichen als 90° gewählt, wodurch der erste und zweite Schenkel somit zueinander im Wesentlichen parallel verlaufen. Die Klemme wird so an der Wandöffnung angebracht, dass die Schenkel an den jeweils gegenüberliegenden, voneinander wegweisenden Wandflächen zu liegen kommen und als Verbindungselement an der Innenseite der Gebäudeöffnung anliegt. anliegt. Alle weiteren Merkmale ergänzen sich analog oben.The use of a clamp can alternatively be described as a method for assembling a window or door element in a wall opening, wherein a clamp is used as a fastening base, which comprises a first leg, a second leg and a connecting element between them as essential elements. The length W of the connecting element is selected (or prefabricated) so that it corresponds to the thickness D of the wall, to which the clamp is to be attached (in the area of the reveal, parapet or lintel). The angle α between the first leg and the connecting element and the angle β between the second leg and the connecting element are selected essentially as 90 °, whereby the first and second legs thus run essentially parallel to one another. The clamp is attached to the wall opening in such a way that the legs come to rest on the opposite wall surfaces pointing away from one another and rests as a connecting element on the inside of the building opening. is applied. All other features complement each other analogously above.

Since such clamps can be manufactured as stamped / bent parts, it is possible without great effort to provide different clamp widths W (connecting element length) according to the usual building standard wall thicknesses. The angles α and β denote the angles between legs 10, 20 and connecting element 30. In Figure 2 the clamp has different leg lengths L1 and L2.

Figur 3 zeigt einen Schenkel 10, 10', 20, 20' einer Klemme mit einer Durchbohrung 70 an ihrem dem Verbindungselement fernen Ende. Figure 3 shows a leg 10, 10 ', 20, 20' of a clamp with a through-hole 70 at its end remote from the connecting element.

Figur 4 zeigt eine Klemme 100' in Schrägansicht mit den unterschiedlich lang ausgelegten Schenkeln 10' und 20', wobei das Verbindungselement 30' eine Sickenstruktur 90 aufweist. Figure 4 shows a clamp 100 'in an oblique view with the legs 10' and 20 'of different lengths, the connecting element 30' having a bead structure 90.

Figur 5 ist eine Skizze einer Wandöffnung mit vier an der Laibung verbauten Klemmen 100. Die zum Betrachter weisenden Schenkel 10 sind mit den an die Öffnung 80 grenzenden Wandregionen (Vorderseite 40) verbunden, die Schenkel 20 sind unsichtbar an der Rückseite 50 verankert. Das Verbindungselement 30 stellt die Verbindung zwischen den beiden Schenkeln 10, 20 dar und zieht sich über die Innenseite 60 hin (Brüstung, Laibung, Sturz) Das Koordinatenkreuz zeigt die Öffnung in der x-z-Ebene. Ein einzubauendes Tür-oder Fensterelement wird folgerichtig parallel zur x-z-Ebene in y-Richtung justiert (Lage in der Laibung) und relativ zur Wandöffnung in x und z-Richtung ausgerichtet. Figure 5 is a sketch of a wall opening with four clamps 100 installed on the reveal. The legs 10 facing the viewer are connected to the wall regions (front side 40) bordering the opening 80, the legs 20 are invisible on the rear 50 anchored. The connecting element 30 represents the connection between the two legs 10, 20 and extends over the inside 60 (parapet, soffit, lintel). The coordinate cross shows the opening in the xz plane. A door or window element to be installed is consequently adjusted parallel to the xz plane in the y direction (position in the reveal) and aligned in the x and z directions relative to the wall opening.

Figur 6 verwendet dieselbe Orientierung wie Figur 5 und zeigt also einen Horizontalquerschnitt in der x-y-Ebene. In der Wandöffnung 80 sind - hier seitlich - zwei Klemmen verankert, wobei die Schenkel 10, 20 und das Verbindungselement 30 eng an der Innenseite bzw. der Vorder- und Rückseite 40, 50 anliegen. Figure 6 uses the same orientation as Figure 5 and thus shows a horizontal cross section in the xy plane. Two clamps are anchored in the wall opening 80 - here on the side - with the legs 10, 20 and the connecting element 30 resting closely on the inside or the front and rear sides 40, 50.

Figur 7 schliesslich zeigt eine Draufsicht auf das Verbindungselement 30 einer Klemme 100 bzw. 100', mit Sicken 90. Figure 7 finally, shows a top view of the connecting element 30 of a clamp 100 or 100 ′, with beads 90.
