Description

Die Erfindung bezieht sich auf einen Sturz für eine einen Stockrahmen eines Fensters oder einer Tür aufnehmende Maueröffnung mit nebeneinandergereihten Sturzelementen, die aus mit Beton ausgießbaren Ziegelschalen und gegebenenfalls aus einem Rolladenkasten bestehen.The invention relates to a lintel for a frame frame of a window or a door receiving wall opening with juxtaposed lintel elements, which consist of castable concrete brick shells and optionally of a roller shutter box.

Stürze für Fenster oder Türen aus nebeneinandergereihten, einen im wesentlichen U-förmigen Querschnitt aufweisenden Ziegelschalen, die nach einer Bewehrungseinlage mit Beton ausgefüllt werden, stellen zwar eine gute Tragfähigkeit sicher, bilden aber Kältebrücken, die den Wärmeschutz einer Wand nachhaltig beeinträchtigen können. Zur Verbesserung der Wämedämmung im Sturzbereich von Fenstern oder Türen ist es bekannt (EP 0 382 708 A1, DE 19 613 775 A1), die nebeneinandergereihten Sturzelemente aus einzelnen in Längsrichtung des Sturzes hintereinandergereihten Einzelziegeln aufzubauen, die in Längsrichtung des Sturzes durchgehende, nach oben offene Hohlräume einerseits zur Aufnahme einer bewehrten Betonfüllung und anderseits einer Wärmedämmeinlage aufweisen, die vorzugsweise durch vom Boden des Ziegels aufragende Stege von den Betonfüllungen getrennt ist. Die Teilfüllung der Sturzelemente mit einer Wärmedämmeinlage bringt zwar einen verbesserten Kälteschutz der Wand im Sturzbereich mit sich, doch bleibt die verstärkte Wärmedämmung insbesondere im Bereich eines in die Maueröffnung eingesetzten Stockrahmens eines Fensters oder einer Tür unzureichend. Dazu kommt, daß Sturzelemente mit einer zusätzlichen Füllung aus einem wärmedämmenden Werkstoff aufwendiger zu fertigen sind und eine geringere Belastbarkeit mit sich bringen.Falls for windows or doors of juxtaposed, a substantially U-shaped cross-section having brick shells that are filled with concrete after a reinforcement insert, while ensuring a good load capacity, but form cold bridges that can permanently affect the thermal insulation of a wall. To improve the insulation in the lintel area of windows or doors, it is known (EP 0 382 708 A1, DE 19 613 775 A1) to construct the side-by-side lintel elements of individual individual bricks arranged one behind the other in the longitudinal direction of the lintel, which open upwards in the longitudinal direction of the lintel Have cavities on the one hand for receiving a reinforced concrete filling and on the other hand, a thermal insulation insert, which is preferably separated by rising from the bottom of the brick ridges of the concrete fillings. Although the partial filling of the lintel elements with a thermal insulation insert brings with it improved protection against cold of the wall in the lintel area, the reinforced thermal insulation remains inadequate, in particular in the area of a floor frame of a window or a door inserted into the wall opening. In addition, lintel elements are more expensive to manufacture with an additional filling of a heat-insulating material and bring a lower load capacity with it.

Um im Sturzbereich eine Funktionstrennung zwischen der Tragkonstruktion und einer Wärmedämmung zu erreichen, ist es darüber hinaus bekannt (DE 27 00 724 A1), zwischen zwei von mehreren nebeneinandergereihten Sturzelementen einen der Wärmedämmung dienenden, hohlen Füllziegel aus gebranntem Ton einzusetzen, der die benachbarten Sturzelemente mit seitlich abstehenden Brandstegen übergreift. Durch diese Füllziegel können die Wärmeverluste solcher Stürze verringert werden. Nachteilig ist allerdings, daß hohle Füllziegel aus gebranntem Ton einen zusätzlichen Herstellungsaufwand mit sich bringen und daß die tragenden Sturzelemente trotz der Füllziegel nur eine beschränkte Wärmedämmung der Stürze ergeben, selbst wenn die tragenden Sturzelemente aus Schwerbeton mit einer Schale aus Keramik oder Leichtbeton versehen sind.In order to achieve a functional separation between the supporting structure and a thermal insulation in the lintel area, it is also known (DE 27 00 724 A1), between two of several side-by-side lintel elements to use a thermal insulation serving, hollow filler brick of baked clay, which engages over the adjacent lintel elements with laterally projecting fire bars. Through this filling the heat losses of such falls can be reduced. The disadvantage, however, is that hollow clay tiles from baked clay bring an additional manufacturing effort and that the supporting lintel elements despite the filler only result in limited thermal insulation of the falls, even if the supporting lintel elements are made of heavy concrete with a shell made of ceramic or lightweight concrete.

Der Erfindung liegt somit die Aufgabe zugrunde, einen Sturz für ein Fenster oder eine Tür der eingangs geschilderten Art so auszugestalten, daß eine vorteilhafte Wärmedämmung im Bereich des Stockrahmens erreicht wird, und zwar mit einfachen Konstruktionsmaßnahmen.The invention is therefore based on the object, a fall for a window or a door of the type described in such a way that an advantageous thermal insulation in the area of the floor frame is achieved, with simple design measures.

Die Erfindung löst die gestellte Aufgabe dadurch, daß im Bereich des Stockrahmens zwischen zwei Sturzelementen ein Wärmedämmprofil eingesetzt ist, das die benachbarten Sturzelemente auf der Sturzoberseite mit seitlich abstehenden Randstegen übergreift und aus einem einen Wärmedämmstoff aufnehmenden Hohlprofil aus Kunststoff besteht.The invention solves the problem set by the fact that in the area of the floor frame between two lintel elements, a thermal insulation profile is used, which engages the adjacent lintel elements on the lintel top with laterally projecting edge webs and consists of a heat insulating female hollow profile made of plastic.

Durch das Vorsehen eines zwischen zwei Sturzelementen eingesetzten Wärmedämmprofils im Bereich des Stockrahmens wird im Bereich des Stockrahmens eine von den Wärmedämmeigenschaften der anschließenden Sturzelemente unabhängige Wärmedämmung des Sturzes sichergestellt, wodurch die Wärmeverluste der Wand erheblich verringert werden können, obwohl die anschließenden Sturzelemente aufgrund der Ziegelschale nur beschränkte Wärmedämmeigenschaften aufweisen. Das Wärmedämmprofil kann daher wie die bekannten Füllziegel in den zwischen entsprechenden Sturzelementen vorgesehenen Längsspalt eingehängt werden, bevor auf den Sturz über die Sturzelemente mit dem eingefügten Wärmedämmprofil hinweg ein Mörtelbett zum Versetzen von Mauersteinen in der Druckzone oberhalb des Sturzes aufgebracht wird. Das auf der Wandaußenseite an das Wärmedämmprofil anschließende Sturzelement kann im Bedarfsfall durch einen Rolladenkasten gebildet werden, der in diesem Fall vorteilhaft in den Sturz eingebunden werden kann.By providing a thermal insulation profile used between two lintel elements in the area of the floor frame, a thermal insulation of the lintel independent of the thermal insulation properties of the subsequent lintel elements is ensured in the area of the floor frame, whereby the heat losses of the wall can be significantly reduced, although the subsequent lintel elements due to the brick shell only limited Have thermal insulation properties. The thermal insulation profile Therefore, like the known filling tiles can be hung in the provided between corresponding camber elements longitudinal gap before applied to the lintel over the lintel elements with the inserted thermal insulation profile away a mortar bed for moving bricks in the pressure zone above the lintel. If necessary, the lintel element adjoining the thermal insulation profile on the outside of the wall can be formed by a roller shutter box, which in this case can advantageously be incorporated into the lintel.

Das Wärmedämmprofil besteht aus einem Hohlprofil aus Kunststoff, das einen im wesentlichen U-förmigen Querschnitt zur Aufnahme eines Wärmedämmstoffes aufweisen kann. Günstigere Verhältnisse insbesondere hinsichtlich der Eigenfestigkeit und des Schutzes des Wärmedämmstoffes können dadurch sichergestellt werden, daß das Hohlprofil als mit Kunststoff ausgeschäumtes Hohlkammerprofil ausgebildet wird.The thermal insulation profile consists of a hollow profile made of plastic, which may have a substantially U-shaped cross section for receiving a thermal insulation material. Cheaper conditions, in particular with regard to the inherent strength and the protection of the thermal insulation material can be ensured that the hollow profile is formed as a plastic foam-filled hollow chamber profile.

In der Zeichnung ist der Erfingungsgegenstand beispielsweise dargestellt, und zwar wird ein erfindungsgemäßer Sturz für ein Fenster oder eine Tür in einem vereinfachten Querschnitt gezeigt.In the drawing, the subject of the invention is shown, for example, and that an inventive fall for a window or a door in a simplified cross section is shown.

Der Sturz 1 besteht in herkömmlicher Weise aus einzelnen Sturzelementen 2, die nebeneinandergereiht in einem Mörtelbett auf den Auflagern 4 versetzt sind, die durch eine die Maueröffnung für das Fenster oder die Tür bildende Wand 5 erhalten werden. Die Sturzelemente 2 bestehen aus Ziegelschalen 6, die eine Bewehrung 7 für eine Betonfüllung 8 aufnehmen. Die Sturzelemente 2 könnten aber auch einen anderen Aufbau aufweisen und neben der Betonverfüllung einen Einsatz aus einem Wärmedämmwerkstoff aufnehmen.The lintel 1 is conventionally composed of individual lintel elements 2 which are juxtaposed in a mortar bed on the supports 4 obtained by a wall 5 forming the wall opening for the window or the door. The lintels 2 consist of brick shells 6, which receive a reinforcement 7 for a concrete filling 8. However, the lintel elements 2 could also have a different structure and record in addition to the concrete filling an insert made of a thermal insulation material.

Um im Bereich eines in die Maueröffnung eingesetzten Stockrahmens 9 für ein Fenster oder eine Tür besondere Wärmedämmeigenschaften für den Sturz 1 zu erreichen, ist zwischen Sturzelementen 2 im Bereich des Stockrahmens 9 ein Wärmedämmprofil 10 eingesetzt, das mit seitlich abstehenden Randstegen 11 die benachbarten Sturzelemente 2 auf der Sturzoberseite übergreift und daher in sehr einfacher Weise zwischen die benachbarten Sturzelemente 2 eingehängt werden kann. Das Wärmedämmprofil 10 besteht aus einem die Randstege 11 bildenden Hohlprofil 12 aus Kunststoff, das im Ausführungsbeispiel eine mit einem Schaumstoff 13 ausgeschäumte Hohlkammer bildet.In order to achieve special thermal insulation properties for the lintel 1 in the area of a floor frame 9 inserted into the wall opening for a window or door, a thermal insulation profile 10 is inserted between lintel elements 2 in the region of the floor frame 9, the adjacent lintel elements 2 with laterally projecting edge webs 11 the fall top overlaps and therefore can be hung in a very simple manner between the adjacent lintel elements 2. The heat-insulating profile 10 consists of a the edge webs 11 forming hollow section 12 made of plastic, which forms a foam-filled with foam 13 in the embodiment.

Auf den Sturz 1 mit dem eingehängten Wärmedämmprofil 12 wird dann ein Mörtelbett 14 zum Versetzen von Mauersteinen 15 aufgebracht, die einen mit dem Sturz 1 als Zuggurt wirkenden Druckgurt bilden. Der Stockrahmen 9 für ein Fenster oder eine Tür ist dann im Bereich des Wärmedämmprofils 10 in herkömmlicher Weise zu versetzen.On the lintel 1 with the suspended heat-insulating profile 12, a mortar bed 14 is then applied for moving masonry blocks 15, which form a pressure belt acting with the lintel 1 as a tension belt. The floor frame 9 for a window or a door is then placed in the region of the thermal insulation profile 10 in a conventional manner.

Die Erfindung ist selbstverständlich nicht auf das dargestellte Ausführungsbeispiel beschränkt. So ist es beispielsweise möglich, das auf der Wandaußenseite an das Wärmedämmprofil 10 anschließende Sturzelement 2 in Form eines Rolladenkastens auszubilden, ohne daß sich hinsichtlich des Einsatzes des Wärmedämmprofiles 10 Änderungen ergeben, das dann in denfreibleibenden Längspalt zwischen dem Rolladenkasten auf der Wandaußenseite und dem innenseitig anschließenden Sturzelement 2 über die seitlich abstehenden Randstege 11 eingehängt wird.The invention is of course not limited to the illustrated embodiment. Thus, for example, it is possible to form the on the outside of the wall to the thermal insulation profile 10 subsequent lintel element 2 in the form of a roller shutter box, without resulting in the use of the thermal insulation profile 10 changes, which then infrefreibenden longitudinal gap between the roller shutter box on the wall outside and the inside subsequent Crash element 2 is hooked over the laterally projecting edge webs 11.
