Description

Die Erfindung bezieht sich auf eine Deckenrandschalung für eine armierte oder nicht armierte betonierte Decke, bestehend aus einer wärmedämmenden Platte, deren Außenseite mit der Fassade fluchtet, und einer an der Innenseite der wärmedämmenden Platte befestigten, senkrecht zur Fassade orientierten Abstützung in Form eines Steges, und der Steg mit seiner Unterseite mit der Unterseite der Decke fluchtet.The invention relates to a slab formwork for a reinforced or non-reinforced concrete Blanket consisting of a heat insulating Slab, the outside of which is flush with the facade, and one on the inside of the thermal insulation Panel attached, oriented perpendicular to the facade Support in the form of a web, and the Bridge with its bottom with the bottom of the The ceiling is in alignment.

Zur Erstellung von Mauerwerken werden wärmedämmende Bausteine verwendet, mit denen beispielsweise die Heizkosten des fertiggestellten Bauwerks aufgrund ihres hohen Isolationsvermögens erheblich reduzierbar sind. Im Bereich der auf den Mauerwerken randseitig abgestützen betonierten Decken werden dem Fachmann bekannte Deckenrandschalungen verwendet, um Wärmeverluste im Bereich der horizontal nach außen weisenden Stirnseiten der Decken zu minimieren. Mit ihnen wird, besonders bei armierten Stahlbetondecken, die Ausbildung von Wärmebrücken vom Gebäudeinneren nach Außen verhindert. Aus der auf den Anmelder zurückgehenden DE 295 12 807.0 ist eine Deckenrandschalung bekannt, bestehend aus einer Decke mit einem hohen Isolationsvermögen, an deren der Decke zugewandten Innenseite ein senkrecht zur Plattenebene orientierter Steg befestigt ist, wobei Ober- und Unterkante der Platte mit der Ober- und Unterseite der Decke im wesentlichen fluchten und die Unterseite des Steges mit der Unterseite der Platte fluchtet. Die Außenseite der wärmedämmenden Platte schließt bündig an die Außenseiten des darunter- bzw. darüberliegenden Mauerwerks an. Mit dem horizontal ausgerichteten Steg, der dem Schalungsbauteil ein im wesentlichen L-förmiges Profil verleiht, wird die Deckenrandschalung auf dem darunter befindlichen Mauerwerk befestigt, z. B. festgeklebt oder mit Mörtel fixiert. Der Steg dient einerseits zur Vergrößerung der Kontaktfläche zwischen Mauerwerk und Schalungsbauteil und andererseits zur Abstützung der wärmedämmenden Platte, um sie während der Montage und dem Ausgießen der Decke mit flüssigem Beton in ihrer senkrechten Lage zu fixieren. Nach der Erstarrung des Gußmaterials verbleibt das Schalungselement an Ort und Stelle, und seine Außenseite wird zum Bestandteil der Fassade des Bauwerks.To create masonry, thermal insulation Blocks used with, for example, the Heating costs of the completed structure due to their high insulation capacity can be reduced considerably are. In the area of the edges on the masonry supported concrete ceilings Expertly known slab edge formwork used to heat loss in the area horizontally to the outside to minimize pointing ends of the ceilings. With them, especially with reinforced concrete floors, the formation of thermal bridges from inside the building prevented to the outside. From the to the Applicant declining DE 295 12 807.0 is one Ceiling edge formwork known, consisting of a Blanket with a high insulation capacity on the other the inside of the ceiling facing perpendicular to Plate level oriented web is attached, wherein Top and bottom edge of the plate with the top and Basically aligned and underside of the ceiling the bottom of the web with the bottom of the Plate is aligned. The outside of the thermal insulation Plate closes flush with the outside of the or overlying masonry. With the horizontally aligned web, the formwork component gives an essentially L-shaped profile, the slab edge formwork is on the one below located masonry attached, for. B. glued or fixed with mortar. The bridge serves on the one hand to increase the contact area between masonry and formwork component and on the other hand for support the thermal insulation panel to keep it going mounting and pouring the ceiling with liquid Fix concrete in its vertical position. This remains after the solidification of the casting material Formwork element in place, and its outside becomes part of the facade of the building.

Als nachteilig bei den bisher bekannten Deckenrandschalungen ist anzusehen, daß lediglich die Ausbildung stirnseitiger, d. h. im wesentlichen in horizontaler Richtung nach Außen reichender, Wärmebrücken unterbunden ist. Jedoch an den Ober- und Unterkanten der Deckenrandschalung ist der Wärmedurchgang von der betonierten Decke nach Außen praktisch nicht unterbunden. Da die für diesen Steg vorgeschlagenen Werkstoffe im allgemeinen ein schlechteres Isolationsvermögen als die wärmedämmende Platte aufweisen, können nach unten Wärmeverluste auftreten, da das Schalungsbauteil hier nur über ein lokal reduziertes Isolationsvermögen verfügt. Außerdem ist der Wärmedurchgang von der Decke nach schräg unten oder oben und Außen nicht durch zusätzliche wärmedämmende Schichten, die ein höheres Isolationsvermögen aufweisen als die Bausteine des Mauerwerks, unterbunden.A disadvantage of the previously known slab edge formwork it can be seen that only training face, d. H. essentially in horizontal Towards outward-reaching thermal bridges is prevented. However, on the top and bottom edges the ceiling edge formwork is the heat transfer practical from the concrete ceiling to the outside not prevented. Because the ones proposed for this dock Materials generally a worse one Insulation than the heat insulation Have plate, heat loss down occur because the formwork component here only over has a locally reduced insulation capacity. In addition, the heat transfer from the ceiling is behind diagonally below or above and outside not by additional insulating layers that have a higher Insulation than the building blocks of Masonry, prevented.

Aus der DE 299 08 673 sind Ringankerschalungen mit Armierungen und nach oben und unten sich anschließenden Formsteinen bekannt, die nach außen zu mit einer wärmedämmmenden Platte eine thermische Isolierung erfahren haben und die in ihrer vertikalen Ausdehnung durch Ringanker und Formsteine definiert werden.DE 299 08 673 includes ring anchor formwork Reinforcements and adjoining up and down Shaped stones known to face the outside with thermal insulation have experienced and in their vertical Expansion defined by ring anchors and shaped stones become.

Ausgehend vom Stand der Technik hat sich die Erfindung zur Aufgabe gestellt, eine Deckenrandschalung derart weiterzubilden, daß die Ausbildung von Wärmebrücken im Bereich der oberen und unteren Ecken oder Kanten der Stirnseiten einer betonierten Decke verhindert wird.Based on the prior art, the invention tasked with slab edge formwork to train such that the formation of thermal bridges in the area of the upper and lower corners or edges of the faces of a concrete ceiling is prevented.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die wärmedämmende Platte mit ihrer Ober- und Unterkante im wesentlichen symmetrisch über die Ober- und Unterseite der Decke übersteht.According to the invention, this object is achieved by that the thermal insulation panel with its top and Bottom edge essentially symmetrical about the The top and bottom of the blanket protrude.

Der Kerngedanke der Erfindung besteht darin, daß die wärmedämmende Platte nach oben und unten über die Stirnseite der betonierten Decke übersteht, wobei diese Überstände im wesentlichen symmetrisch zueinander sind. D. h. daß die Höhe der Platte größer ist als die Stärke der Decke. Die Unterseite des horizontalen, an der Innenseite der wärmedämmenden Platte befestigten Steges fluchtet dabei mit der Unterseite der betonierten Decke. Das wärmedämmende Material der Platte ist frei wählbar, es muß lediglich über ausreichende Formstabilität verfügen, um nicht zusätzliche Abstützungen beim Ausgießen verwenden zu müssen. Die Montage des wärmedämmenden Schalungselementes an dem Mauerwerk erfolgt dabei derart, daß auf der Krone des Mauerwerks ein in seiner Breite gegenüber dem übrigen Mauerwerk reduzierter Baustein aufgesetzt ist, wobei die Reduzierung der Breite der Stärke der wärmedämmenden Platte entspricht. Die Unterseite des Steges liegt dann unmittelbar auf dem Baustein reduzierter Breite auf und kann in geeigneter Weise befestigt, z. B. festgeklebt werden. Der unter die Decke nach unten überstehende Teil der wärmedämmenden Platte liegt dabei an der nach Außen weisenden Stirnseite des schmaleren Bausteins an. Anschließend wird die armierte oder nicht armierte Decke mit flüssigem Beton ausgegossen und nach Erstarrung des Gußmaterials auf der Oberseite der Decke ein weiterer in seiner Breite reduzierter Mauerstein aufgesetzt, wobei dessen Oberseite mit der Oberkante der wärmedämmenden Platte in einer Ebene liegt, um eine horizontale Mauerwerkskrone um Aufbau des weiteren Mauerwerks zu bilden. Die Außenseite der wärmedämmenden Platte wird, wie bereits bekannt, zum Bestandteil der Fassade.The main idea of the invention is that the thermal insulation board up and down over the face of the concrete ceiling protrudes, whereby these supernatants are essentially symmetrical to each other. I.e. that the height of the plate is larger is as the thickness of the blanket. The bottom of the horizontal, on the inside of the thermal insulation Plate attached web aligns with it the bottom of the concrete ceiling. The heat insulating The material of the plate is freely selectable, it must only have sufficient dimensional stability, to avoid additional supports when pouring to have to use. The assembly of the thermal insulation Formwork element on the masonry doing so that on the crown of the masonry in width compared to the rest of the masonry reduced block is placed, the reduction the width of the thickness of the thermal insulation Plate corresponds. The bottom of the web lies then immediately reduced to the block Width and can be attached in a suitable manner, z. B. be glued. The one under the covers part of the thermal insulation panel protruding below lies on the outside facing end of the narrower block. Then the reinforced or non-reinforced ceiling with liquid Poured concrete and after solidification of the casting material another in on the top of the blanket reduced brick width, its top with the top edge of the heat insulating Plate lies in one plane to a horizontal one Masonry crown to build further To form masonry. The outside of the thermal insulation As already known, the plate becomes a component the facade.

Der Vorteil der Erfindung besteht darin, daß an den stirnseitigen Eckbereichen der Decke die Bildung von Wärmebrücken nach Außen unterbunden ist, da sich die wärmedämmende Platte nach oben bzw. unten über die Decke hinaus erstreckt, und dadurch der unmittelbare Wärmefluß nach schräg unten bzw. oben und Außen unterbunden ist. Desweiteren ist verhindert, daß Wärme durch das zumeist schlecht wärmeisolierende Material des horizontalen Steges nach Außen abfließen kann, da dieser, wie weiter unten ausgeführt, über keinen unmittelbaren Kontakt zur Umgebung verfügt.The advantage of the invention is that frontal corner areas of the ceiling formation is prevented by thermal bridges to the outside, because the thermal insulation board up or down extends beyond the ceiling, and thereby the immediate heat flow diagonally downwards or upwards and is prevented from the outside. Furthermore, it is prevented that heat from the mostly poorly heat-insulating Material of the horizontal web Outside can drain, as this, as below executed, no direct contact with the Environment.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand von Unteransprüchen.Advantageous embodiments of the invention are the subject of subclaims.

Vorteilhafterweise besteht die wärmedämmende Platte aus extrudiertem Polystyrol, das aufgrund seiner geschlossenzelligen Struktur keine Feuchtigkeit aufnimmt, witterungsbeständig ist, sowie über einen hohen Wärmedämmwert verfügt, da die abgeschlossenen Poren des Werkstoffs untereinander und zur Umgebung keinen Luftaustausch zulassen. Aufgrund seiner gegenüber anderen geschäumten Kunststoffen hohen Dichte sowie der Formstabilität eignet es sich besonders zur Herstellung von Verschalungen, da weitere Abstützungen odgl. nicht notwendig sind, wie dem Fachmann bekannt.The heat-insulating plate is advantageously made made of extruded polystyrene, which due to its closed cell structure no moisture records, is weatherproof, as well as over a has high thermal insulation value because the completed Pores of the material with each other and with the environment do not allow air exchange. Because of its opposite other foamed plastics high Density and dimensional stability make it particularly suitable for the production of formwork, as there are more Supports or the like are not necessary how known to the expert.

Als Material für den horizontalen Steg werden die im Bauwesen wohl bekannten Werkstoffe Faserzement, Metall, Holz oder Kunststoff vorgeschlagen. Der Faserzement kann unter anderem Fasern aus Metall, Kunststoff, Glas oder Mineralien enthalten, die ihm, je nach den bestehenden Anforderungen, die gewünschten Materialeigenschaften wie Zug- und/oder Druckfestigkeit, geringes Gewicht oder Feuchtigkeitsbeständigkeit verleihen. Der Steg kann auch aus Span- oder Vollholz oder einem Hartkunststoff, wie beispielsweise PVC angefertigt werden. Als metallische Werkstoffe kommen unter anderem Aluminium oder Eisenbleche in Betracht.The material used for the horizontal web is Fiber cement, well known in construction, Metal, wood or plastic suggested. The Fiber cement can include metal fibers, Contain plastic, glass or minerals that depending on the existing requirements Material properties such as tensile and / or Compressive strength, light weight or moisture resistance to lend. The jetty can too made of chipboard or solid wood or a hard plastic, such as PVC. As a metallic Materials include aluminum or sheet iron.

Zur Befestigung des Stegs an der wärmedämmenden Platte wird vorgeschlagen, daß diese an ihrer zur Decke weisenden Innenseite mit einer horizontal verlaufenden Nut auszustatten, in die der Steg eingesetzt wird. Zur Fixierung des Stegs in der Nut wird vorgeschlagen, ihn mit einem auf die vorliegende Materialkombination abgestimmten Klebstoff einzukleben.For attaching the web to the thermal insulation It is proposed that this at their for Ceiling facing inside with a horizontal equip the running groove into which the web is inserted becomes. For fixing the web in the groove is proposed to him with a present Material combination of coordinated adhesive glued.

Alternativ dazu kann an den horizontal ausgerichteten Steg randseitig ein senkrecht dazu orientierter Winkel angeformt sein, der nach oben und/oder unten weist. Ist der angeformte Winkel nur in eine Richtung orientiert, d. h. weist er nur nach oben oder unten, erhält der Steg ein im wesentlichen L-förmiges Profil, wobei beide Schenkel vorteilhafterweise dieselbe Länge aufweisen. Steht der angeformte Winkel nach beiden Seiten im wesentlichen symmetrisch über, so erhält der Steg ein ungefähr T-förmiges Profil. Zur Befestigung des Stegs an der wärmedämmenden Platte wird ebenfalls vorgeschlagen, daß der senkrecht orientierte Winkel an oder auf der Platte mit einem geeigneten Klebstoff festgeklebt wird. Prinzipiell ist es auch möglich, einen Steg mit einem daran angeformten Winkel in einer Nut versenkt an der Platte zu befestigen.Alternatively, you can use the horizontally aligned one A vertically oriented web on the edge Angled, the up and / or down has. The molded angle is only in one direction oriented, d. H. it only points upwards or below, the web is given an essentially L-shaped shape Profile, with both legs advantageously have the same length. Is the molded angle essentially symmetrical on both sides over, the web receives an approximately T-shaped Profile. For attaching the web to the thermal insulation Plate is also suggested that the vertically oriented angles on or on the plate is glued with a suitable adhesive. In principle, it is also possible to use a web with a molded angle sunk in a groove to attach to the plate.

Die Größe der Überstände der wärmedämmenden Platte nach oben bzw. unten über die Ober- und Unterseite der Decke hinaus ist im Rahmen der Erfindung beliebig wählbar, besonders wird jedoch vorgeschlagen, daß die Summe der symmetrischen Überstände der Stärke der betonierten Deckenplatte entspricht, d. h. daß die Höhe der wärmedämmenden Platte doppelt so groß ist wie die Stärke der Decke. Damit wird die Ausbildung von Wärmebrücken an den oberen und unteren stirnseitigen Kanten der Decke nach schräg oben bzw. unten und Außen wirkungsvoll verhindert, da das wärmedämmende Material der Platte, das üblicherweise ein höheres Isolationsvermögen als die Bausteine des Mauerwerks aufweist, weit über die Decke übersteht und damit ein direkter Wärmeübergang schräg in die Umgebung unterbunden ist.The size of the protrusions of the thermal insulation board up or down over the top and bottom the blanket is arbitrary in the context of the invention selectable, but it is particularly suggested that the sum of the symmetrical projections of the Corresponds to the thickness of the concrete slab, d. H. that the height of the thermal insulation panel is double is as big as the thickness of the blanket. So that will the formation of thermal bridges on the upper and lower front edges of the ceiling slanting effectively prevented above or below and outside, because the thermal insulation material of the panel, which is usually greater insulation than that Has building blocks of masonry far beyond that Ceiling protrudes and thus a direct heat transfer is obliquely prevented in the environment.

Um das Aufbringen einer Putzschicht auf der Außenseite der wärmedämmenden Platte zu erleichtern bzw. die Anbringung eines zusätzlichen Haftgrundes auf dieser Oberfläche einzusparen, wird vorgeschlagen, daß die nach Außen weisende Oberfläche der wärmedämmenden Platte strukturiert oder aufgerauht ist, um eine verbesserte Haftung des Putzes zu erhalten. Diese Strukturierung kann bereits bei der Erstellung der Platte oder auch nachträglich in einem weiteren Bearbeitungsschritt vom Fachmann realisiert werden.To apply a layer of plaster on the outside to facilitate the heat-insulating plate or the application of an additional primer to save this surface, it is suggested that the outward-facing surface of the thermal insulation Plate is structured or roughened, to get better adhesion of the plaster. This structuring can already be done during creation the plate or later in one further processing step realized by a specialist become.

Um einen verbesserten Kraftschluß zwischen wärmedämmender Platte und/oder Steg einerseits sowie dem Mauerwerk bzw. der auszugießenden Decke andererseits zu erhalten, wird vorgeschlagen, daß Platte und/oder Steg mit einer Grundierung beschichtet sind, die eine verbesserte Haftung zwischen den einzelnen Bauteilen vermittelt. Insbesondere kann in die Grundierung Sand eingestreut sein, um mit dieser Aufrauhung die Kontaktfläche zwischen den Bauteilen zu vergrößern.To improve the adhesion between thermal insulation Plate and / or web on the one hand and the Masonry or the ceiling to be poured on the other hand to get it is suggested that plate and / or web coated with a primer are that have improved liability between the individual components conveyed. In particular, can to be sprinkled in the primer sand in order to this roughening the contact area between the Enlarge components.

Der horizontal orientierte Steg kann mit Löchern in Form vertikal orientierter Durchbrüche versehen sein, in die Haken oder Bügel eingehängt werden, um eine unmittelbare Verbindung der Deckenrandschalung mit einer in der Decke vorhandenen Armierung zu erhalten. Beim Ausgießen, bei dem durch den hydrostatischen Druck des flüssigen Betons horizontal nach Außen wirkende Kräfte auf das Schalungsbauteil ausgeübt werden, ist damit die zusätzliche außenseitige Abstützung überflüssig. Desweiteren kann auf den Steg eine Mörtelmasse aufgebracht werden, die die Löcher ausfüllt und in unmittelbaren Kontakt zum darunterliegenden Baustein steht. Damit kann das Schalungsbauteil in einfacher und schneller Weise am Mauerwerk befestigt werden.The horizontally oriented web can have holes in Provide the form of vertically oriented openings be hooked or hooked around a direct connection of the slab edge formwork with existing reinforcement in the ceiling. When pouring, with the hydrostatic Pressure of the liquid concrete horizontally External forces exerted on the formwork component is the additional outside No need for support. Furthermore, on a mortar mass is applied to the bridge fills the holes and in direct contact to the underlying block. So that can the formwork component in easier and faster Way to be attached to the masonry.

Oberhalb des ersten Stegs kann ein zweiter, vertikal beabstandet zum ersten, an der wärmedämmenden Platte befestigt sein. Insbesondere wird vorgeschlagen, daß er mit seiner Oberseite fluchtend mit der Oberseite der Decke in analoger Weise zum ersten Steg an der Platte befestigt ist. Damit kann die kraftschlüssige Verbindung zwischen Platte und Decke verbessert werden, da die Kontaktfläche zwischen beiden Bauteilen mit dem Steg vergrößert ist. Desweiteren, beispielsweise wenn der zweite Steg ebenfalls mit Öffnungen versehen ist, wird eine weitere Befestigung des Schalungselements an einer vorhandenen Armierung mit Haken oder Bügeln ermöglicht.Above the first web, a second, vertical spaced from the first, at the thermal insulation Plate attached. In particular, it is proposed that he was flush with his top with the top of the ceiling in an analogous manner to the first Bridge is attached to the plate. So that can the positive connection between plate and Ceiling can be improved since the contact area between both components with the bridge is enlarged. Furthermore, for example if the second web is also provided with openings, a further fastening of the formwork element to a existing reinforcement with hooks or brackets.

Die wärmedämmende Platte (1) ist mit einem horizontal, d. h. senkrecht zur Ebene der Platte (1), orientierten Steg (2) ausgestattet, der hier in eine Nut eingesetzt und beispielsweise mit einem geeigneten Klebstoff befestigt ist, wobei die Unterseite des Stegs (2) unmittelbar auf der Oberseite des in seiner Breite reduzierten Bausteins (3a) aufliegt. Zur Vereinfachung der Darstellung wurde auf die Darstellung einer Armierung in der Decke (4), die mit flüssigem Beton ausgegossen wird, verzichtet. Die wärmedämmende Platte (1) steht mit ihrer Ober- und Unterkante praktisch symmetrisch über die Ober- und Unterseite der Decke (4) über, um den Wärmefluß an den stirnseitigen Ecken oder Kanten der Decke (4) nach schräg oben oder unten und Außen zu unterbinden. Nach Erstarrung des Gußmaterials wird ein weiterer in seiner Breite reduzierter Baustein (3b) auf die Decke (4) aufgebracht, dessen Höhe dem Überstand der Platte (1) über die Decke (4) nach oben entspricht. Das Mauerwerk (3) weist auf seiner Außen- und Innenseite eine zusätzliche Verputzung (5,6) auf, die beispielsweise bei einer strukturierten Außenseite der wärmedämmenden Platte (1) unmittelbar auf sie aufgebracht werden kann. Die Decke (4) ist mit einer Fußbodenbeschichtung (7) beliebigen Aufbaus versehen.In the embodiment shown in Figure 1 the invention is a masonry (3), for example made of Porotonoder Gas concrete blocks with a relatively high Isolation ability, the top building block (3a) in width compared to the one below Masonry (3) is reduced by an amount the thickness of the thermal insulation board (1) corresponds to the ceiling edge formwork. So that is achieved that the outside of this plate (1) with the surrounding masonry (3) is practically flush. The heat-insulating plate (1) is with a horizontal, d. H. perpendicular to the plane of the Plate (1), oriented web (2) equipped, the inserted here in a groove and for example with a suitable adhesive is attached, the Underside of the web (2) directly on the top of the reduced building block in width (3a) rests. To simplify the presentation was based on the representation of a reinforcement in the Ceiling (4) poured with liquid concrete is waived. Thermal insulation board (1) is practically symmetrical with its top and bottom edge across the top and bottom of the blanket (4) over to the heat flow at the front corners or edges of the ceiling (4) obliquely upwards or to prevent below and outside. After solidification of the Casting material is reduced in width Module (3b) applied to the ceiling (4), the height of which protrudes from the plate (1) corresponds to the ceiling (4) upwards. The masonry (3) points on its outside and inside an additional plastering (5,6), for example with a structured outside of the heat-insulating plate (1) applied directly to it can be. The ceiling (4) is with a Provide floor coating (7) of any structure.
