Description

Wärmedämmendes Schalungselement, insbesondere zur Herstellung der Schalung einer Bodenplatte eines Gebäudes und Verfahren zur Herstellung einer derartigen Heat-insulating shuttering element, in particular for producing the formwork of a floor slab of a building and method for producing such
Schalungformwork
Die Erfindung betrifft ein wärmedämmendes Schalungselement, insbesondere zur Herstellung der Schalung einer Bodenplatte eines Gebäudes. Die Erfindung bezieht sich ferner auf ein Verfahren zur Herstellung einer Bodenplattenschalung aus derartigen Schalungselementen.The invention relates to a thermally insulating shuttering element, in particular for the production of the formwork of a floor slab of a building. The invention further relates to a method for producing a bottom plate formwork of such formwork elements.
Die Herstellung wärmegedämmter Bodenplatten mit Hilfe wärmedämmender Schalungselementen ist z.B. aus der DE 101 03 470 AI bekannt. Dabei werden auf ein Schotterbett zunächst aus druckbeständigem Polystyrol-Extruderschaum gebildete Platten gelegt. Auf diese Platten werden dann L-fόrmige Randelemente zu einem umlaufenden geschlossenen äußeren Rahmen miteinander verbunden und der verbleibende Zwischenraum mit einer Dämmlage ausgefüllt. Anschließend wird eine Folie auf die derart hergestellte wannen- förmige Schalung gelegt, um zu verhindern, daß Zementmilch in die Fugen der Dämmlage gelangen kann, und die Randelemente außenseitig mittels einer Schotterfüllung fixiert. Danach erfolgt dann das Eingießen des Betons in die wannenformige, aus den wärmedämmenden Schalungselementen bestehende Schalung zur Bildung der Bodenplatte.The production of thermally insulated floor panels by means of thermally insulating formwork elements is e.g. known from DE 101 03 470 AI. In this case, plates formed on a ballast bed initially made of pressure-resistant polystyrene extruder foam. On these plates then L-shaped edge elements are connected to a circumferential closed outer frame together and filled the remaining space with an insulating layer. Subsequently, a foil is placed on the trough-shaped formwork produced in this way in order to prevent cemented milk from getting into the joints of the insulating layer, and fix the edge elements on the outside by means of ballast filling. Thereafter, then the pouring of the concrete in the trough-shaped, consisting of the insulating formwork elements formwork to form the bottom plate.
Als nachteilig hat sich bei Verwendung dieser bekannten Schalungselemente unter anderem erwiesen, daß zwischen den Randelementen und der Dämmlage häufig keine ausreichende Form- und/oder Kraftschlußverbindung besteht, so daß trotz außenseitiger Schot- terfüllung eine zusätzliche Abstützung, z.B. eine Holzschalung, zur Verhinderung des Auseinanderdrückens der Randelemente erforderlich sein kann. Außerdem sind bei den bekannten Schalungselementen die Randelemente lediglich in Umfangsrichtung über eine Nut/Federverbindung miteinander verbunden und können sich seitlich gegeneinander verschieben, so daß trotz der Schotterabstützung das Entstehen einer ungleichmäßigen Randkontur z.B. beim Eingießen des Betons in die durch die Schalungselemente gebildete Wanne nicht ausgeschlossen werden kann.A disadvantage has proved when using these known formwork elements, inter alia, that between the edge elements and the insulating layer often no sufficient form and / or frictional connection is made, so that despite outside Schot- terfüllung an additional support, such as a timber formwork, to prevent the pushing apart of the edge elements may be required. In addition, in the known formwork elements, the edge elements are interconnected only in the circumferential direction via a groove / spring connection and can move laterally against each other, so that despite the ballast support the emergence of an uneven edge contour, for example when pouring the concrete into the tray formed by the formwork elements are not excluded can.
Der Erfindung liegt die Aufgabe zugrunde, wärmedämmende Schalungselemente anzugeben, mit denen insbesondere eine wannenförmige Schalung für die Herstellung der Bodenplatte eines Gebäudes aufbaubar ist, wobei eine zusätzliche Abstützung, z.B. durch eine Holzschalung oder eine Schotterfύllung, entfallen kann. Ferner soll ein Verfahren zur Herstellung einer Bodenplattenschalung aus derartigen Schalungselementen angegeben werden.The invention has for its object to provide heat-insulating formwork elements with which in particular a trough-shaped formwork for the production of the bottom plate of a building can be built, with an additional support, e.g. by a timber formwork or a gravel filling, can be omitted. Furthermore, a method for producing a floor slab formwork from such formwork elements is to be specified.
Diese Aufgabe wird erfindungsgemäß hinsichtlich der Schalungselemente durch die Merkmale des Anspruchs 1 und hinsichtlich des Verfahrens durch die Merkmale des Anspruchs 12 gelöst. Weitere, besonders vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche.This object is achieved with respect to the formwork elements by the features of claim 1 and in terms of the method by the features of claim 12. Further, particularly advantageous embodiments of the invention disclose the dependent claims.
DieΕrfindung beruht im wesentlichen auf dem Gedanken, die Ober- und/oder Unterseite der Schalungselemente mit noppenförmigen Verbindungselementen zu versehen, die derart angeordnet sind, daß aus benachbarten Verbindungselementen Vertiefungen gebildet werden, in welche bei der bestimmungsgemäßen Verwendung des Schalungselementes entsprechende noppenformige Verbindungselemente mindestens eines als Verbindungsplatte (im folgenden auch als Deckplatte bezeichneten) ausgebildeten Schalungselementes formschlüssig eingreifen, um benachbarte Schalungselemente miteinander zu verbinden.The invention is based essentially on the idea to provide the top and / or bottom of the formwork elements with knob-shaped connecting elements which are arranged such that depressions are formed from adjacent connecting elements, in which in the intended use of the formwork element corresponding noppenformige connecting elements at least one Connecting plate (hereinafter referred to as cover plate) formed formwork element engage positively to connect adjacent formwork elements together.
Als besonders vorteilhaft hat es sich erwiesen, wenn die noppenförmigen Verbindungselemente eine im wesentlichen pyramidenstumpfförmige Gestalt aufweisen, wobei die einzelnen Pyramidenstümpfe in ihrem unteren Bereich miteinander verbunden sein können.It has proven to be particularly advantageous if the knob-shaped connecting elements have a substantially truncated pyramidal shape, wherein the individual truncated pyramids can be connected to one another in their lower region.
Die erfindungsgεmäßen Schalungselemente können jeweils eine unterschiedliche äußere Gestalt aufweisen. Dabei hat es sich insbesondere zum Aufbau wannenformiger Schalungen für die Herstellung von Bodenplatten als zweckmäßig erwiesen, sowohl plattenförmige Schalungselemente, die auf ihrer Ober- und Unterseite noppenförmige Verbindungselemente aufweisen (Grundplatten) als auch plattenförmige Schalungselemente, die nur auf ihrer Ober- oder Unterseite noppenförmige Verbindungselemente tragen (Deckplatten), sowie winkelförmig ausgebildete Randelemente zu bevorraten, die mindestens einen vertikalen und einen horizontalen Schenkel besitzen, wobei Letzterer ober- und/oder unterseitig mit noppenförmigen Verbindungselementen versehen ist. Je nach Ausgestaltung der Schalung können die Randelemente auch als Außeneck- oder Inneneckelemente ausgebildet sein.The formwork elements according to the invention can each have a different outer Have shape. It has proved to be particularly useful for building tannenformiger formwork for the production of floor slabs, both plate-shaped formwork elements having on its top and bottom knob-shaped connecting elements (base plates) and plate-shaped formwork elements, the knob-shaped fasteners only on its top or bottom bear (cover plates), as well as angle-shaped edge elements to stockpile, which have at least one vertical and one horizontal leg, the latter being provided on top and / or bottom side with knob-shaped connecting elements. Depending on the configuration of the formwork, the edge elements may also be formed as Außeneck- or Inneneckelemente.
Zur Herstellung einer wannenförmigen Bodenplattenschalung werden zunächst eine entsprechende Anzahl von Randelementen (einschließlich der erforderlichen Anzahl von Ek- kelementen) seitlich miteinander verbunden. Der dadurch entstehende Rahmen wird dann durch bündig nebeneinander angeordneten Grundplatten ausgefüllt, so daß eine geschlossene Grundwanne aus Schalungselementen entsteht. Anschließend erfolgt dann die Verbindung der Grundplatten mit den Randelementen, indem Deckplatten mit ober- und/oder unterseitig angeordneten noppenförmigen Verbindungselementen über und/oder unter die Grundplatten der Grundwanne und über und/oder unter die horizontalen Schenkel der Randelemente gelegt werden und die noppenförmigen Verbindungselemente der Deckplatten in die Vertiefungen der jeweils gegenüberliegenden Grundplatten und Randelemente gedrückt werden.To produce a trough-shaped bottom plate formwork, first of all a corresponding number of edge elements (including the required number of corner elements) are connected to one another laterally. The resulting frame is then filled by flush mounted side by side base plates, so that a closed base tub made of formwork elements. Subsequently, then the connection of the base plates with the edge elements by cover plates with top and / or bottom side arranged knob-shaped connecting elements and / or below the base plates of the base trough and placed over and / or under the horizontal legs of the edge elements and the knob-shaped connecting elements of Cover plates are pressed into the recesses of the respective opposite base plates and edge elements.
Bei einer derartigen, durch die erfindungsgemäßen Schalungselemente gebildeten wannenförmigen Schalung können sich beim Eingießen des Betons zur Bildung der Bodenplatte des entsprechenden Gebäudes die Randelemente seitlich nicht verschieben, da die nocken- förmigen Verbindungselemente der Deckplatte formschlüssig in die entsprechenden Vertiefungen der Grundplatten und der Randelemente eingreifen.In such a trough-shaped formwork formed by the formwork elements according to the invention, the edge elements can not move laterally during pouring of the concrete to form the bottom plate of the corresponding building, since the cam-shaped connecting elements of the cover plate engage positively in the corresponding recesses of the base plates and the edge elements.
Um in die erfindungsgemäß hergestellte warmenfbrmige Schalung möglichst ohne besondere Abdichtmaßnahmen Beton eingießen zu können, hat es sich als vorteilhaft erwiesen, wenn die Abmessungen der Deckplatten derart gewählt werden, daß sie den gesamten Raum zwischen den senkrechten Schenkeln der Randelemente ausfüllen und somit insbe- sondere die Fugen benachbarter unterer Schalungselemente überdecken.In order to be able to pour concrete into the hot-formed formwork produced according to the invention as far as possible without special sealing measures, it has proved to be advantageous if the dimensions of the cover plates are selected such that they fill the entire space between the vertical limbs of the edge elements and thus cover the joints of adjacent lower formwork elements.
Ferner hat es sich als besonders zweckmäßig erwiesen, wenn der mittlere Abstand benachbarter noppenförmiger Verbindungselemente entsprechend dem jeweils normenmäßig vorgeschriebenen Bauraster (in Deutschland: 6,25 cm) gewählt wird.Furthermore, it has proved to be particularly useful if the average distance between adjacent knob-shaped connecting elements is selected according to the respective standard prescribed construction grid (in Germany: 6.25 cm).
Um bereits bei der Herstellung des aus den Randelementen bestehenden Rahmens einer unerwünschten möglichen seitlichen Verschiebung der Randelemente entgegenzuwirken, hat es sich außerdem als vorteilhaft erwiesen, wenn die Stirnseiten der Randelemente über entsprechende Vorsprünge und Nuten formschlüssig miteinander verbindbar sind, derart, daß sich z.B. eine Schwalbenschwanzfύhrung oder eine Flachführung o.dgl. ergibt. Zur Verbindung benachbarter Randelemente werden diese daher vorzugsweise nicht seitlich zusammengesteckt, sondern entlang von Führungen randseitig ineinandergeschoben.In order to counteract an undesired lateral displacement of the edge elements already during the production of the frame elements, it has also proved advantageous if the end faces of the edge elements can be positively connected to one another via corresponding projections and grooves such that e.g. a Schwalbenschwanzfύhrung or a flat guide or the like. results. For the connection of adjacent edge elements they are therefore preferably not laterally plugged together, but pushed together along guides at the edges.

In Fig. l ist mit 1 ein wärmedämmendes Schalungselement (Grundplatte), z.B. aus einem Polystyrolschaum, zur Bildung einer Bodenplatte eines Gebäudes bezeichnet. Die Grundplatte 1 weist sowohl auf ihrer Oberseite 2 als auch auf ihrer Unterseite 5 jeweils eine Vielzahl gleichmäßig verteilt angeordneter, noppenförmiger Verbindungselemente 3 auf. Die noppenförmigen Verbindungselemente 3 besitzen eine im wesentlichen pyramiden- stumpfförmige Gestalt und sind derart angeordnet, daß jeweils von vier Verbindungsele- menten 3 eine Vertiefung 4 gebildet wird, in welche ein entsprechendes noppenförmiges Verbindungselement eines ober- oder unterseits angeordneten weiteren Schalungselementes eingreifen kann.In Fig. 1, 1 denotes a thermally insulating formwork element (base plate), e.g. from a polystyrene foam, to form a floor slab of a building. The base plate 1 has both on its upper side 2 and on its underside 5 in each case a multiplicity of uniformly distributed, knob-shaped connecting elements 3. The knob-shaped connecting elements 3 have a substantially truncated pyramidal shape and are arranged such that each of four Verbindungsele- elements 3 a recess 4 is formed, in which a corresponding knob-shaped connecting element of an upper or lower side arranged further formwork element can intervene.
Fig.2 zeigt ein erfindungsgemäßes Schalungselement 11 (Deckplatte) mit einer eine glatte Oberfläche aufweisenden Oberseite 12. In diesem Ausfuhrungsbeispiel befinden sich die mit 13 bezeichneten noppenförmigen Verbindungselemente und die durch die Verbindungselemente gebildeten Vertiefungen 14 auf der Unterseite 15 des Schalungselementes 11.2 shows a formwork element 11 according to the invention (cover plate) with a top surface 12 having a smooth surface. In this exemplary embodiment, the knob-shaped connection elements designated by 13 and the depressions 14 formed by the connection elements are located on the underside 15 of the formwork element 11.
In Fig.3 ist ein erfindungsgemäßes Schalungselement 21 dargestellt, bei dem es sich um ein als Außeneckelement ausgebildetes Randelement handelt. Es weist einen im wesentlichen L-förmigen Querschnitt auf. Auf der Oberseite 22 sowie auf der Unterseite 25 des horizontalen Schenkels 27 sind wiederum noppenförmige Verbindungselemente 23 und Vertiefungen 24 angeordnet.In Figure 3, a formwork element 21 according to the invention is shown, which is a designed as Außeneckelement edge element. It has a substantially L-shaped cross-section. On the top 22 and on the bottom 25 of the horizontal leg 27 turn knob-shaped connecting elements 23 and recesses 24 are arranged.
Zur Verbindung des Eckelementes 21 mit weiteren seitlich angeordneten Randelementen 41 (vgl. auch Fig.4) weist das Eckelement 21 in einem Teilbereich seiner ersten Stirnfläche 28 des vertikalen Schenkels 29 schwalbenschwanzförmig ausgebildete nutenförmige Ausnehmungen 30 und an der zweiten Stirnfläche 31 entsprechende leistenförmige VorsprüngeTo connect the corner element 21 with further laterally arranged edge elements 41 (see also Fig. 4), the corner element 21 has dovetailed recesses 30 dovetail-shaped in a partial region of its first end face 28 of the vertical leg and strip-shaped projections corresponding to the second end face 31
32 auf.32 on.
Damit bei den relativ rauen Praxisbedingungen die zu verbindenden Randelemente 21 schnell in eine genau definierte senkrechte Lage verschoben werden können, befinden sich an den Enden der nutenförmigen Ausnehmungen 30 Anschläge 26, deren Flächen leicht abgeschrägt sind, um zu verhindern, daß sich in diesen Bereichen Wasser sammeln kann.So that the edge elements 21 to be connected can be quickly moved into a precisely defined vertical position in the relatively rough conditions of practice, there are at the ends of the groove-shaped recesses 30 stops 26, whose surfaces are slightly chamfered to prevent water can collect in these areas.
Außerdem sind die Eckelemente 21 und auch die sich anschließenden weiteren Randelemente 41 derart ausgebildet, daß die Wandstärke des jeweiligen Randelementes im unteren Bereich 42 des vertikalen Schenkels 29 außenseitig größer ist als in dessen oberen Bereich 43. Durch eine derartige Ausgestaltung der Randelemente 21, 41 wird berücksichtigt, daß nach der Herstellung der Betonbodenplatte der Wärmedurchgang im unteren Sockelbereich am größten ist und durch eine entsprechende Wärmedämmung in diesem Bereich berücksichtigt werden sollte.In addition, the corner elements 21 and the subsequent further edge elements 41 are formed such that the wall thickness of the respective edge element in the lower region 42 of the vertical leg 29 is greater on the outside than in the upper region 43. By such a configuration of the edge elements 21, 41 is takes into account that after the production of the concrete floor slab, the heat transfer in the lower base area is greatest and should be taken into account by an appropriate thermal insulation in this area.
Anhand des in den Fig.4 und 5 dargestellten Ausführungsbeispieles läßt sich der Zusammenbau entsprechender Schalungen zur Herstellung von Bodenplatten aus erfindungsgemäßen Schalungselementen 1 , 1 1, 21, 41 entnehmen.Based on the embodiment shown in Figures 4 and 5, the assembly of corresponding formwork for the production of floor panels from formwork elements 1, 1 1, 21, 41 according to the invention can be found.
Dabei werden zunächst die Randelemente (einschließlich der Eckelemente) 21, 41 seitlich miteinander verbunden, so daß sich ein Rahmen ergibt, der mit lose nebeneinander verlegten Grundplatten 1 ausgefüllt wird (in Fig.4 ist lediglich aus Übersichtlichkeitsgründen nur eine Grundplatte 1 dargestellt). Anschließend erfolgt die Verbindung der Grundplatten 1 mit den Randelementen 21, 41, indem Deckplatten 11 derart auf die vorgefertigte Grundwanne gelegt werden, daß sie jeweils eine Grundplatte 1 und den horizontalen Schenkel 27 eines Randelementes 21, 41 überdecken (Fig.5).In this case, first the edge elements (including the corner elements) 21, 41 connected to each other laterally, so that a frame results, which is filled with loose side by side laid base plates 1 (in Figure 4, only one base plate 1 is shown for reasons of clarity). Subsequently, the connection of the base plates 1 with the edge elements 21, 41 by 11 cover plates are placed on the prefabricated base trough so that they each cover a base plate 1 and the horizontal leg 27 of a peripheral element 21, 41 (Figure 5).
Die Erfindung ist selbstverständlich nicht auf die vorstehend beschriebenen Ausführungsbeispiele beschränkt. So können beispielsweise die Schalungselemente nicht nur plattenförmige oder L-förmige, sondern auch andere Formen aufweisen. Beispielsweise wäre denkbar, sie für den Aufbau von wärmegedämmten Zwischenwänden Doppel-L-formig auszubilden. Außerdem kann es sich bei den Eckelementen auch um Inneneckelemente handeln (vgl. Fig.6).The invention is of course not limited to the embodiments described above. Thus, for example, the formwork elements not only plate-shaped or L-shaped, but also have other shapes. For example, it would be conceivable for the construction of thermally insulated partitions double L-form. In addition, the corner elements may also be inner corner elements (see FIG.
Ferner müssen die noppenförmigen Verbindungselemente nicht zwingend pyramiden- stumpfförmig ausgebildet sein, wenngleich sich diese Noppenform in der Praxis besonders bewährt hat. Um ein seitliches Verschieben der übereinander liegenden Schalungselemente mit ineinander eingreifenden noppenförmigen Verbindungselementen sicher zu vermeiden, sollte darauf geachtet werden, daß sich durchgehende, über die Oberfläche erstreckende rillen- oder nutenförmige Vertiefungen für die Verbindungselemente bei dem jeweiligen Schalungselement vermieden werden.Furthermore, the knob-shaped connecting elements do not necessarily have to be designed in the shape of a truncated pyramid, even though this knobbed shape has proven particularly useful in practice. To a lateral displacement of the superposed formwork elements to safely avoid with intermeshing knob-shaped connecting elements, care should be taken that continuous, extending over the surface groove or groove-shaped depressions are avoided for the connecting elements in the respective shuttering element.
Schließlich ist es auch möglich, die Grundplatten (d.h. Platten mit ober- und unterseitig angeordneten noppenförmigen Verbindungselementen) als Deckplatten zu verwenden. Dieses ist insbesondere dann zweckmäßig, wenn die Wandstärke der wannenförmigen Schalung bodenseitig verdoppelt werden soll. In diesem Fall kann beispielsweise unter den Randelementen 21, 41 und unter den in Fig.4 und 5 dargestellten Grundplatten 1 eine weitere Lage mit Grundplatten 1 angeordnet werden, die sich dann bis an den äußeren Rand der entsprechenden Randelemente 21 , 41 erstreckt. Diese als Deckplatte verwendete Grundplatte verbindet dann ebenfalls die Randelemente mit den innerhalb des Rahmens angeordneten Grundplatten. Finally, it is also possible to use the base plates (ie plates with top and bottom arranged knob-shaped connecting elements) as cover plates. This is particularly useful when the wall thickness of the trough-shaped formwork is to be doubled on the bottom side. In this case, for example, under the edge elements 21, 41 and under the base plates 1 shown in Figures 4 and 5, a further layer with base plates 1 are arranged, which then extends to the outer edge of the corresponding edge elements 21, 41. This base plate used as a cover plate then also connects the edge elements with the arranged inside the frame base plates.
