Abstract

A method for casting a concrete lintel over a door or window space uses a U-shaped mould (3) assembled from three sections (7a, 7b, 7c) of sandwich board. This has two outer skins (8) and an inner insulating layer (9). The adjoining edges of the mould are shaped to ensure that the inner surface of the mould presents a smooth surface for the concrete while the outer surface is also continuous and ready for rendering. The stepped adjoining edges also prevent thermal bridges at the edges.

Description

Die Erfindung betrifft ein verlorenes Schalungselement für einen Sturz, insbesondere für eine Tür- oder Fensteröffnung, mit einem U-förmigen Querschnitt, jeweils einer U-förmigen Innenseite und Außenseite, einen wenigstens zwei-schichtigen Aufbau aus einem Dämmaterial und wenigstens einem Putzgrund, z.B. einer Kaschierung, wobei zwischen der Innenseite und der Außenseite durchgehend jeweils wenigstens eine Schicht des Dämmaterials angeordnet ist.The invention relates to a lost formwork element for a fall, in particular for a door or window opening, with a U-shaped cross section, respectively a U-shaped inside and outside, at least one two-layered construction of an insulating material and at least one plaster base, e.g. a lamination, being between the inside and the outside continuously at least one layer of the insulating material is arranged.

Schalungselemente für Stürze sind grundsätzlich bekannt. Neben einer Verschalung des Sturzes vor Ort mit Hilfe von Schalungselementen, welche nach dem Aushärten des Sturzes wieder entfernt werden, können Stürze auch mittels verlorener, also in dem Bauwerk verbleibenden Schalungselementen hergestellt werden.Shuttering elements for falls are basically known. In addition to a shuttering of the fall on site with Help of formwork elements, which after curing can be removed from the fall again, falls also by lost, so remaining in the building Shuttering elements are produced.

Dazu wäre es beispielsweise denkbar, den durch die EP 0 589 292 B1 beschriebenen Schalungswinkel in der Art zu erweitern, bzw. zwei Schalungswinkel derartig zu kombinieren, dass ein U-förmiges Element entsteht, welches als verlorenes Schalungselement für den Sturz Verwendung finden kann.For this it would be conceivable, for example, by the EP 0 589 292 B1 described formwork angle in the Art to expand, or two formwork angles such combine to create a U-shaped element, which as a lost formwork element for the fall Can be used.

Derartig aufgebaute Schalungselemente weisen jedoch den gravierenden Nachteil auf, dass sie keine vollständige Isolierung des Sturzes sicherstellen, da zumindest die Grundplatte gemäß dem oben genannten Patent aus einer zementgebundenen Span- oder Holzwolleplatte ausgebildet ist. Selbst bei einer weitergehenden Isolierung, beispielsweise durch Einkleben eines Isolationsmaterials auf den Bereich der Unterseite, würde durch die direkte Verbindung der Schichten der Schalungswände mit der Bodenplatte eine Kältebrücke entstehen, welche den modernen Anforderungen an die Isolierung von Bauwerken entgegensteht.However, such formwork elements have the serious disadvantage that they are not complete Ensure isolation of the fall, since at least the base plate according to the above-mentioned patent from a cement-bonded particleboard or wood wool board is trained. Even with a more extensive Isolation, for example by gluing a Insulation material on the area of the underside, would be through the direct connection of the layers of the Formwork walls with the bottom plate a cold bridge arise, which meets the modern requirements of the Isolation of structures precludes.

Ein weiterer Nachteil besteht darin, dass das Zusammenstellen von verlorenen Schalungselementen für Stürze aus bestehenden, herkömmlichen Schalungswinkeln für Decken oder dergleichen einen sehr großen Aufwand vor Ort auf der Baustelle bedeutet, welcher wiederum mit großen Zeitverlusten, Kosten und Unsicherheiten in der baulichen Ausführung verbunden ist.Another disadvantage is that the compilation of lost formwork elements for falls from existing, conventional formwork angles for Ceiling or the like a very big effort Place on the construction site means, which in turn with large time losses, costs and uncertainties in the structural design is connected.

Die DE 26 58 620 beschreibt ein Schalungselement mit einer Isolierschicht, welche eine Außenschicht aus Faserbeton aufweist, an deren Rückseite die Isolierschicht angepresst ist, und wobei auf der Rückseite der Isolierschicht eine Innenschicht aus Faserbeton aufgespritzt wird, so dass aus ihrer naturrauen freiliegenden Oberfläche Faserenden frei hervorstehen. Die Faserenden werden vom Ortbeton umhüllt. Der Ortbeton fließt in die Unebenheiten der rauen Oberfläche hinein. Dadurch wird eine innige Verbindung zwischen dem Ortbeton und dem Faserbeton der Innenschicht des Schalungselements geschaffen. Mit einem derartigen Schalungselement lässt sich eine Schalung mit durchgehend aufweisender Isolierschicht erzeugen.DE 26 58 620 describes a formwork element with an insulating layer comprising an outer layer of fiber concrete has, at the back of the insulating layer is pressed on, and being on the back the insulating layer has an inner layer of fiber concrete is sprayed so that out of her natural-gray exposed Surface fiber ends protruding freely. The Fiber ends are encased in in-situ concrete. The in-situ concrete flows into the bumps of the rough surface. This creates an intimate connection between the In-situ concrete and the fiber concrete of the inner layer of the formwork element created. With such a formwork element can be a formwork with continuous produce insulating layer.

Ein wesentlicher Nachteil eines derartigen Schalungselements ist die Verwendung von Faserbeton als Putzgrund, welcher ein sehr hohes Gewicht aufweist, sich schlecht bearbeiten lässt und einen großen Zeitaufwand für die Bearbeitung aufweist.A major disadvantage of such a formwork element is the use of fiber concrete as a primer, which has a very high weight, itself badly editable and a lot of time for editing.

Es ist daher die Aufgabe der Erfindung, ein verlorenes Schalungselement für einen Sturz zu schaffen, welches eine leichte Handhabung, eine leichte Verarbeitbarkeit und einen sehr guten Wärmeschutz ermöglicht. It is therefore the object of the invention, a lost Shuttering element to create a fall, which easy handling, easy to process and a very good thermal protection allows.

Erfindungsgemäß wird diese Aufgabe durch wenigstens drei U-förmig angeordnete Platten, welche jeweils einen wenigstens zwei-schichtigen Aufbau aus dem Dämmaterial und wenigstens einer Schicht des Putzgrunds aufweisen, und welche im Bereich ihrer Verbindung mit der benachbarten Platte jeweils eine stufenartige Ausbildung aufweisen, wobei die Platten im Bereich der stufenartigen Ausbildung miteinander verklebt sind, gelöst.According to the invention, this object is achieved by at least three U-shaped plates, each one at least two-layered construction of the insulating material and at least one layer of the plaster base and which are in the area of their connection with the adjacent plate each have a step-like design have, wherein the plates in the range of step-like training are glued together solved.

Auf diese Art entsteht erfindungsgemäß eine im Querschnitt U-förmige verlorene Schalung für den Sturz, die einerseits einen Putzgrund aufweist, andererseits durchgehend wenigstens eine Schicht des Dämmaterials hat und durch den Aufbau aus wenigstens drei Platten die Herstellung des erfindungsgemäßen verlorenen Schalungselementes sehr einfach und in vorteilhafter Weise kostengünstig ist, da es aus den entsprechenden Platten sehr einfach zugeschnitten und hergestellt, z.B. verklebt, werden kann. Das so aus den wenigstens drei Platten bestehende Schalungselement kann als Fertigteil verwendet werden, wodurch eine Standardisierung mit den entsprechenden Vorteilen bezüglich Kostensenkung und Vereinfachung verbunden ist.In this way arises according to the invention in cross section U-shaped lost formwork for the fall, on the one hand has a plaster base, on the other hand continuously at least one layer of the insulating material has and by building out at least three plates the production of the lost formwork element according to the invention very easy and in an advantageous way Cost-effective, as it comes from the appropriate plates very easily tailored and manufactured, e.g. glued, can be. That's the least of the three Plates existing formwork element can be used as a finished part be used, creating a standardization with the corresponding benefits in terms of cost reduction and simplification.

Auf diese Weise ist sichergestellt, dass der komplette Sturz eine kältebrückenfreie Wärmedämmung aufweist und durch den Putzgrund einerseits eine gute Verbindbarkeit mit dem später folgenden Putzgrund und/oder dem später den Sturz bildenden Beton gewährleistet ist. In this way it is ensured that the complete Fall has a cold bridge-free thermal insulation and on the one hand a good connectivity through the plaster base with the later following plaster base and / or the later the fall forming concrete is guaranteed.

Ein weiterer Vorteil des erfindungsgemäßen Schalungselements liegt in einem sehr geringen Gewicht im Vergleich zu den herkömmlichen Elementen, was einerseits den Transport zur Baustelle erleichtert und andererseits beim Transport auf der Baustelle Hebemittel, Kranen oder dergleichen einspart.Another advantage of the formwork element according to the invention is in a very low weight in comparison to the conventional elements, what on the one hand facilitates the transport to the site and on the other hand during transport at the construction site lifting gear, Saves cranes or the like.

Werden die stufenförmigen Ausbildungen gemäß der Erfindung in herkömmliche Platten eingearbeitet, so können diese bei einem gleichzeitigen Toleranzausgleich so zusammengefügt werden, dass der Putzgrund der jeweiligen Platten sowohl im Bereich der Außenseite als auch im Bereich der Innenseite aneinander stößt, so dass die Außenseite wie auch die Innenseite komplett aus Putzgrund ausgebildet ist. Im Bereich der stufenartigen Ausbildungen, welche beispielsweise in die Platten eingefräst werden können, ist der Putzgrund dagegen zumindest teilweise entfernt, so dass hier eine Verbindung von Dämmaterial auf Dämmaterial ausgebildet wird, wodurch sichergestellt ist, dass es zu keinen Kältebrücken im Bereich der Verbindungsstellen der Platten des verlorenen Schalungselements kommt.Will the stepped formations according to the invention incorporated into conventional plates, so can this with a simultaneous tolerance compensation be joined together so that the plaster base of the respective Plates both in the area of the outside as also in the area of the inside abuts one another, so that the outside as well as the inside is complete is formed from plaster base. In the area of the step-like Training, which, for example, in the Plates can be milled, is the plaster base However, at least partially removed, so here is a Connection of insulating material formed on insulating material which ensures that it is too no cold spots around the joints the plates of the lost formwork element comes.

In einer weiteren sehr günstigen Ausführungsform des Schalungselements ist die Außenseite des U-förmigen Schalungselements durchgehend aus Putzgrund gebildet. Dies stellt einerseits sicher, dass ein auf den Sturz aufzubringender Putz oder dergleichen später sehr gut haften wird, andererseits ermöglicht dies durch die mechanische Stabilität des Putzgrunds, dass das Schalungselement als ein selbsttragendes Element ausgebildet werden kann, welches keinerlei Beplankung, Abstützung oder dergleichen benötigt, während der in das Schalungselement verfüllte Beton aushärtet.In a further very favorable embodiment of the Shuttering element is the outside of the U-shaped Shuttering element formed continuously from plaster base. This on the one hand ensures that one on the fall applied plaster or the like later very well on the other hand, this is made possible by the mechanical stability of the plaster base that the formwork element designed as a self-supporting element can be, which no planking, support or the like required while in the Formwork element cements filled concrete.

In einer weiteren sehr günstigen Ausgestaltung der Erfindung ist außerdem die Innenseite ebenfalls durchgehend aus diesem Putzgrund gebildet.In a further very advantageous embodiment of the invention is also the inside also continuous formed from this plaster base.

Hierdurch wird sichergestellt, dass eine weitere mechanische Festigkeit für das verlorene Schalungselement gewonnen wird. Außerdem wird durch den die komplette Innenseite auskleidenden Putzgrund sichergestellt, dass es zu einer sehr guten Verbindung der in das Schalungselement verfüllten Betonmasse kommt, so dass nach dem Aushärten der Betonmasse eine sehr feste und gut verbundene Einheit aus verlorener Schalung und Beton entsteht, welche dann den wärmegedämmten Sturz bildet.This will ensure that another mechanical Strength for the lost formwork element is won. In addition, by the the complete Ensured lining surface lining, that it is a very good connection of in the formwork element filled concrete mass comes, so that after curing the concrete mass a very solid and well-connected unit of lost formwork and Concrete is created, which then the heat-insulated fall forms.

In einer weiteren sehr vorteilhaften Ausführungsform des Schalungselements weisen sämtliche Platten einen dreischichtigen Aufbau aus zwei Schichten des Putzgrunds und einer dazwischen angeordneten Schicht aus dem Dämmaterial auf. Dieser Aufbau erlaubt eine sehr einfache Herstellung des verlorenen Schalungselements mit den entsprechenden Vorteilen bezüglich den Kosten und in Verbindung mit einer hohen mechanischen Stabilität.In a further very advantageous embodiment of the formwork element, all plates have a three-layered structure consisting of two layers of plaster base and an interposed layer the insulating material. This construction allows a lot simple production of the lost formwork element with the corresponding advantages in terms of costs and in conjunction with a high mechanical stability.

Bei einer derartigen Konstruktion des Schalungselements mit den Platten ist es dabei in sehr vorteilhafter Weise außerdem möglich, dass die beiden seitlichen Platten unterschiedliche Längen aufweisen. Dies kann beispielsweise für eine kombinierte Schalung für den Sturz und eine sich daran anschließende Decke genutzt werden. Im Bereich des Sturzes ist somit keine eigene Verschalung für die Decke notwendig, wodurch der Aufwand sinkt und Material und Kosten eingespart werden können.In such a construction of the formwork element with the plates, it is very beneficial Way also possible that the two lateral Plates have different lengths. This can for example, for a combined formwork for the Camber and an adjoining ceiling used become. In the area of the fall is thus not own Cladding necessary for the ceiling, reducing the effort decreases and material and costs are saved can.

In einer weiteren sehr günstigen Ausbildung des erfindungsgemäßen Schalungselements kann das Dämmaterial aus Steinwolle ausgebildet sein, während es sich in einer vorteilhaften Weiterbildung der Erfindung bei dem Putzgrund um zementgebundene Holzwolle, beispielsweise in Form einer Platte handelt.In a further very favorable embodiment of the invention Shuttering element, the insulating material be made of rock wool while it is in an advantageous embodiment of the invention the plaster base around cement-bound wood wool, for example in the form of a plate.

Dieser Aufbau stellt eine sehr hohe mechanische Stabilität aufgrund der Putzgrundplatten aus zementgebundener Holzwolle sicher, so daß das vergleichsweise instabile Dämmaterial aus Steinwolle ohne Einbußen an mechanischer Festigkeit Verwendung finden kann. In einer Weiterbildung wäre hier auch die Alternative Glaswolle, Mineralgranulat oder dergleichen denkbar, welche zwischen dem Putzgrund gehalten wird.This structure provides a very high mechanical stability due to the plaster base plates made of cement-bound Wood wool sure, so that the comparatively unstable Rockwool insulation without loss of quality mechanical strength can be used. In a Further education would be here also the alternative glass wool, Mineral granules or the like conceivable, which is held between the plaster base.

Ein derartiger Aufbau weist insbesondere bezüglich des Brandschutzes große Vorteile auf, da es sich bei Dämmaterial aus Steinwolle, Glaswolle oder Mineralgranulat, um eine nicht brennbare Isolierung handelt, welche beispielsweise im Bereich von öffentlichen Gebäuden vorgeschrieben ist, mit bisherigen Methoden jedoch nicht zur Isolierung von Stürzen eingesetzt werden konnte.Such a construction, in particular with respect to Fire protection has great advantages, as it is insulating material made of rock wool, glass wool or mineral granules, is a non-combustible insulation, which for example in the area of public buildings is required, with previous methods, however not be used for the isolation of falls could.

Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den restlichen Unteransprüchen und dem anhand der Zeichnung nachfolgend beschriebenen Ausführungsbeispiel.Further advantageous embodiments of the invention result itself from the remaining subclaims and the Based on the drawing embodiment described below.

Es zeigt:

Fig. 2
einen prinzipmäßigen Querschnitt gemäß der Linie II-II in Fig. 1.
It shows:
Fig. 1
a window opening with a fall; and
Fig. 2
a principle cross section along the line II-II in Fig. 1st

Fig. 1 zeigt eine Öffnung 1, hier eine Fensteröffnung 1, in einem Mauerwerk 2 mit einem an sich bekannten Sturz 3. Fig. 1 shows an opening 1, here a window opening 1, in a masonry 2 with a known Fall 3.

Wie in Fig. 2 erkennbar, besteht ein derartiger Sturz 3 zu einem großen Teil aus einem Betonmaterial 4, welches gegebenenfalls auch Armierungen 5 zur Erhöhung der mechanischen Festigkeit enthalten kann. Beim Herstellen eines solchen aus Beton gegossenen Sturzes 3 wird im hier dargestellten Ausführungsbeispiel ein verlorenes Schalungselement 6 benutzt, in welches das Betonmaterial 4 des Sturzes 3 eingegossen wird. Das Schalungselement 6 besteht im hier dargestellten Ausführungsbeispiel aus drei U-förmig angeordneten Verbundplatten 7a, 7b, 7c.As can be seen in Fig. 2, there is such a fall 3 to a large extent of a concrete material 4, which optionally also reinforcements 5 to increase may contain mechanical strength. When manufacturing of such a concrete cast fall 3 is in the embodiment shown here lost formwork element 6 is used, in which the Concrete material 4 of the fall 3 is poured. The Shuttering element 6 consists in the embodiment shown here from three U-shaped composite panels 7a, 7b, 7c.

Jede dieser Platten 7a, 7b, 7c weist einen dreischichtigen Aufbau auf. Der dreischichtige Aufbau besteht jeweils aus zwei Schichten eines Putzgrunds 8, hier dünnen Platten aus zementgebundener Holzwolle, sowie einem dazwischen angeordneten Dämmaterial 9. Je nach Anforderungen an die geforderte Wärmedämmung und die gewünschten Brandschutzbedingungen kann dieses Dämmaterial 9 aus einem aufschäumbaren Kunststoff, wie beispielsweise aus dem unter dem Markennamen Styropor vertriebenen Material, oder aus Steinwolle, Glaswolle oder dergleichen aufgebaut sein.Each of these plates 7a, 7b, 7c has a three-layered Build up. The three-layer structure exists each of two layers of a plaster base 8, here thin sheets of cement-bound wood wool, as well an interposed Dämmaterial 9. Depending on Requirements for the required thermal insulation and the desired fire protection conditions, this insulating material 9 of a foamable plastic, such as from the under the brand name Styrofoam sold material, or rock wool, glass wool or the like.

Der Aufbau aus den vergleichsweise weichen Dämmaterialien 9, wie z.B. Glaswolle oder Steinwolle, ist problemlos möglich, da der Putzgrund 8 eine ausreichende Festigkeit aufweist, um das verlorene Schalungselement 6 auch bei einer entsprechend langen Länge, beispielsweise 3 m, mechanisch so fest auszubilden, daß es als selbsttragendes Schalungselement 6 eingesetzt werden kann.The structure of the relatively soft insulating materials 9, e.g. Glass wool or rock wool, is easy possible because the plaster base 8 sufficient Has strength to the lost formwork element 6 even with a correspondingly long length, for example 3 m, mechanically strong so that it as self-supporting formwork element 6 are used can.

Der hier dargestellte spezielle Aufbau aus den Platten 7a, 7b, 7c erweist sich darüber hinaus als günstig, da sowohl Außenseite 10 als auch Innenseite 11 des verlorenen Schalungselements 6 mit wenigstens annähernd rechtwinkligen Kanten im Bereich der Verbindung der einzelnen Platten 7a, 7b, 7c ausgebildet ist.The special construction shown here from the plates 7a, 7b, 7c also proves to be favorable because both outside 10 and inside 11 of the lost Shuttering element 6 with at least approximately right-angled edges in the area of the connection of the individual plates 7a, 7b, 7c is formed.

Im Bereich der Außenseite 10 erlaubt dies das direkte Verputzen des Sturzes 3 ohne weitere Formgebungsarbeiten. Im Bereich der Innenseite 11 ermöglicht dies, daß die hier prinzipmäßig angedeuteten Armierungen 5 bei ausreichender Ummantelung durch das Betonmaterial 4 in einem relativ weit außen und unten liegenden Bereich angeordnet werden können, was die Stabilität des Sturzes 3 fördert, und was bei verrundeten Kanten im Bereich der Innenseite 11 so nicht möglich wäre.In the area of the outside 10 this allows the direct Plastering the lintel 3 without further shaping work. In the area of the inside 11 this allows the here indicated in principle reinforcements 5 at sufficient sheathing through the concrete material 4 in a relatively far outside and below area can be arranged, indicating the stability of the fall 3 promotes, and what with rounded edges in the area the inside 11 would not be possible.

Die Verbindung der einzelnen Platten 7a, 7c bzw. 7b, 7c untereinander erfolgt hier durch Verkleben von wenigstens annähernd formschlüssigen, stufenartigen Ausbildungen 12 in den jeweils der benachbarten Platte 7a, 7b, 7c zugewandten Bereiche.The connection of the individual plates 7a, 7c or 7b, 7c with each other takes place here by gluing at least approximately form-fitting, step-like formations 12 in each of the adjacent plate 7a, 7b, 7c facing areas.

Die stufenartigen Ausbildungen 12 werden dabei durch ein Ausformen, beispielsweise ein Abfräsen des Plattenmaterials, in der Art ausgeführt, daß wenigstens annähernd formschlüssige, stufenartige Verbindungen entstehen, welche aufgrund ihrer Ausbildung auch bei vergleichsweise großen Fertigungstoleranzen eine hohe Paßgenauigkeit und nach dem Verkleben eine hohe Festigkeit der einzelnen Platten 7a, 7b, 7c untereinander sicherstellen.The step-like formations 12 are doing by a shaping, for example a milling of the plate material, executed in the way that at least approximately form-fitting, stepped connections arise, which due to their training also at comparatively large manufacturing tolerances a high Accuracy and after bonding a high strength the individual plates 7a, 7b, 7c with each other to ensure.

Andererseits wird durch die stufenartigen Ausbildungen 12 der Putzgrund 8 im Bereich der Verbindungen der einzelnen Platten 7a, 7b, 7c untereinander so von dem Dämmaterial 9 entfernt, daß es zu einer durchgehenden Schicht an Putzgrund 8 im Bereich der Innenseite 11 und im Bereich der Außenseite 10 kommt, daß jedoch im Bereich der stufenartigen Ausbildungen 12 zu einem großen Teil das Dämmaterial 9 der einen Platte 7c direkt mit dem Dämmaterial 9 der anderen Platten 7a, 7b in Berührung kommt, so daß hier keine Kältebrücken entstehen.On the other hand, by the step-like training 12 of the plaster base 8 in the area of the compounds of individual plates 7a, 7b, 7c with each other so from the Insulating material 9 removes it to a continuous one Layer of plaster base 8 in the region of the inside 11 and in the area of the outside 10, but that comes in the Area of the step-like formations 12 to a large part of the insulating material 9 of a plate 7c directly with the insulating material 9 of the other plates 7a, 7b comes into contact, so that here no cold bridges arise.

Da die Schichten aus Putzgrund 8 jedoch im Bereich der Außenseite 10 und im Bereich der Innenseite 11 direkt aufeinanderstoßen und hier miteinander verklebt werden können, stellt der Putzgrund 8 eine ausreichend hohe mechanische Festigkeit für die selbsttragende verlorene Schalung 6 sicher.However, since the layers of plaster base 8 in the field of Outside 10 and in the area of the inside 11 directly collide and stick together here can, the plaster base 8 is a sufficiently high mechanical strength for the self-supporting lost Shuttering 6 safe.
