Description

Die Erfindung betrifft zunächst ein Schalungsbauteil zur Bildung einer verlorenen Schalung, in die Beton oder Zement eingefüllt wird, insbesondere Schalungsbauteil für die Bildung des Mantels einer Mantelbetonierung, wobei eine Steckverbindung zwischen zur Anlage aufeinander bestimmten Flächen der aus geschäumten Kunststoff bestehenden Schalungsbauteile vorgesehen ist, die aus, z.B. zapfenartigen, Vorsprüngen und diese aufnehmenden Aussparungen besteht, die in Längsrichtung und in Querrichtung die gleichen Abmessungen und die gleiche Rasterteilung aufweisen. Solche Schalungsbauteile sind aus dem DE-GM 83 21 739 und der DE-OS 25 36 526 bekannt. Ähnliche Schalungsbauteile sind aus CH-PS 616 981 und aus DE-GM 86 01 945.7 bekannt, nur ist dabei keine gleichmäßige Rasterteilung vorgesehen. Derartige Steckverbindungen haben zum einen die Aufgabe, beim Zusammenfügen der einzelnen Schalungsbauteile deren richtige Lage zueinander zu schaffen. Das von den Vorsprüngen bzw. Aussparungen gebildete Grundraster kann z.B. gemäß der zuerst genannten Vorveröffentlichung 25 mm betragen. Die weitere Funktion der Vorsprünge und Aussparungen besteht darin, die einzelnen Bauteile in ihrer Stecklage gegen ein Verschieben aufgrund von Kräften zu sichern, die parallel zu den die Vorsprünge und Aussparungen aufweisenden Flächen verlaufen. Der Nachteil dieser vorbekannten Schalungsbauteile liegt darin, daß an einer Fläche nur Vorsprünge, und an der anderen Fläche nur die Vorsprünge aufnehmende Aussparungen vorgesehen sind. Damit kann ein solches Schalungsbauteil immer nur so mit anderen Schalungsbauteilen zusammengesetzt werden, daß eine Vorsprünge aufweisende Fläche mit einer Aussparungen aufweisenden Fläche zusammengestoßen wird. Das gleiche gilt für die Ausbildung von aufeinandersetzbaren Steinen gemäß der FR-PS 562 166. Abgesehen davon, daß die Steine nach der vorgenannten Literaturstelle nicht ein Schalungsbauteil gemäß dem Oberbegriff des Anspruches 1 sind, sind die obere Fläche und die untere Fläche jedes Steines in einer Weise mit Aussparungen und Vorsprüngen versehen, die lediglich ein Aufstecken der unteren Fläche eines Steines auf die obere Fläche eines anderen Steines ermöglichen. Es sind jedoch hiermit nicht die obere Fläche eines Steines mit der oberen Fläche eines anderen Steines, und auch nicht die untere Fläche eines Steines mit der unteren Fläche eines anderen Steines zusammensteckbar. Dies wird sowohl durch zwischen etwa quadratischen Aussparungen und Vorsprüngen vorhandene, damit in der Formgebung und in den Abmessungen nicht übereinstimmende, in der Draufsicht kreisrunde Vorsprünge verhindert, als auch durch die Ausbildung von diagonal verlaufenden Stegen mit ihren Vorsprüngen und Aussparungen.The invention first relates to a formwork component for forming a lost formwork into which concrete or cement is poured, in particular formwork component for the formation of the shell of a shell concrete, whereby a plug connection is provided between surfaces of the formwork components consisting of foamed plastic, which are made of , for example pin-like, projections and these receiving recesses, which have the same dimensions and the same grid spacing in the longitudinal and transverse directions. Such formwork components are known from DE-GM 83 21 739 and DE-OS 25 36 526. Similar formwork components are known from CH-PS 616 981 and from DE-GM 86 01 945.7, only no uniform grid division is provided. On the one hand, such plug connections have the task of creating their correct position relative to one another when the individual formwork components are joined together. The basic grid formed by the projections or recesses can, for example, according to the first mentioned prior publication be 25 mm. The further function of the projections and recesses is to secure the individual components in their plug-in position against displacement due to forces that run parallel to the surfaces having the projections and recesses. The disadvantage of these previously known formwork components is that only projections are provided on one surface and recesses receiving the projections are provided on the other surface. This means that such a formwork component can only be assembled with other formwork components in such a way that a surface with projections is collided with a surface with recesses. The same applies to the formation of stackable stones according to FR-PS 562 166. Apart from the fact that the stones according to the aforementioned reference are not a formwork component according to the preamble of claim 1, the upper surface and the lower surface of each stone are in one Way with recesses and projections that only allow the lower surface of one stone to be plugged onto the upper surface of another stone. However, this does not allow the upper surface of one stone to be plugged together with the upper surface of another stone, nor the lower surface of a stone with the lower surface of another stone. This is prevented both by approximately existing square recesses and projections, which do not match in shape and dimensions, circular projections which are circular in plan view, as well as by the formation of diagonally extending webs with their projections and recesses.

Die Aufgabe der Erfindung besteht demgegenüber darin, bei einem Schalungsbauteil gemäß dem eingangs zitierten Oberbegriff des Anspruches 1 mehr Varianten des Zusammensetzens solcher Schalungsbauteile zu einer Schalungsteilwand zu schaffen. Dabei soll auch - ohne wesentliche Verluste an Material - die Möglichkeit der Halbierung der Schalungsbauteile oder des Abschneidens von Teilbereichen dieser Bauteile, bei gleichzeitiger Erzielung einer großen Stabilität der Steckverbindung gegeben sein.In contrast, the object of the invention is to provide more variants of assembling such formwork components to form a partial formwork wall in a formwork component according to the preamble of claim 1 cited at the beginning. It should also - without significant losses Material - the possibility of halving the formwork components or cutting off partial areas of these components, while at the same time achieving great stability of the plug connection.

Zur Lösung dieser Aufgabe ist ausgehend von dem eingangs zitierten Oberbegriff des Anspruches 1 vorgesehen, daß jede der beiden Flächen, d.h. sowohl eine obere Fläche als auch eine untere Fläche eines Schalungsbauteiles, die im Betrieb eine Steckverbindung mit einer entsprechenden Gegenfläche eines anderen Schalungsbauteiles eingehen, mit sämtlich einander gleichen und ineinander passenden Vorsprüngen und zwischen den Vorsprüngen befindlichen Aussparungen versehen sind, die in die gleich ausgebildeten Aussparungen und Vorsprünge jeder der Gegenflächen eines weiteren Schalungsbauteiles unter Bildung der Steckverbindung passen, und daß die Vorsprünge oder Aussparungen der einen Fläche (obere Fläche) gegenüber den Vorsprüngen und Aussparungen der anderen Fläche (unteren Fläche) des Schalungsbauteiles um eine Rasterteilung versetzt sind. Damit sind sowohl an der oberen Fläche als auch an der unteren Fläche der Schalungsbauteile jeweils Vorsprünge mit Zwischenräumen sämtlich so angeordnet, daß diese Zwischenräume zwischen den Vorsprüngen Aussparungen bilden, die zur Aufnahme sämtlicher Vorsprünge eines weiteren, darüber oder darunter befindlichen anderen Schalungsbauteiles dienen, wobei die Aussparungen des letztgenannten Schalungsbauteiles sämtliche Vorsprünge des erstgenannten Schalungsbauteiles aufnehmen. Dabei sind die Ausdrücke "obere Fläche" und "untere Fläche" zur Definierung dieser beiden, an entgegengesetzten Seiten der Schalungsbauteile befindlichen Flächen gewählt worden, um das Wesen der vorliegenden Erfindung im Gegensatz zum Stand der Technik zu verdeutlichen. Beim eingangs erwähnten Stand der Technik hat nämlich entweder eine (z.B. die obere Fläche) nur Vorsprünge und die andere (z.B. untere Fläche) nur Aussparungen oder es sind (FR-PS 562 166) unterschiedliche Vorsprünge und Aussparungen an der oberen und der unteren Fläche vorgesehen, die ebenfalls nur ein Ineinanderstecken einer oberen Fläche eines Steines und einer unteren Fläche eines anderen Steines gestatten. Dagegen sind mit der Erfindung sowohl die obere Fläche als auch die untere Fläche gemäß dem vorstehend zitierten Kennzeichen des Anspruches 1 ausgebildet. Man kann somit zum einen sowohl eine obere Fläche und eine untere Fläche eines solchen Schalungsbauteiles aufeinander stecken, aber auch derartige Schalungsbauteile durch das Zusammenstecken zweier oberer Flächen oder zweier unterer Flächen miteinander verbinden. Die Seitenflächen der aufeinandergesteckten Schalungsbauteile sind bei jeder der vorbeschriebenen Steckverbindungen miteinander bündig. Die beiden letztgenannten Varianten haben gegenüber dem Zusammenstecken einer oberen Fläche und einer unteren Fläche den Vorteil, daß bei T- und Eckverbindungen die Rasterteilung halbiert wird. Da bei Erstellung eines Bauwerkes die Höhe der jeweiligen Mauer, Wand oder dergleichen fast niemals gleich einem ganzen Vielfachen der Höhe der Schalungsbauteile ist, müssen die Schalungsbauteile der ersten untersten, oder letzten obersten Reihe gekürzt, d.h. abgeschnitten werden. Die abgeschnittenen Teile sind bei der Anordnung nach dem erläuterten Stand der Technik nicht mehr weiter verwendbar. Bei Schalungsbauteilen nach der Erfindung dagegen können diese Reste jedoch nach Drehen um 180° weiter mit anderen Schalungsbauteilen zusammengesetzt, d.h. wieder verwendet werden. Die hierdurch zu erzielende Kostenersparnis ist erheblich. Das gleiche gilt bei der Erstellung von Giebelwänden, bei denen die Schalungsbauteile gemäß der jeweiligen Dachschräge zugeschnitten werden müssen. Auch hier kann ein schräg abgeschnittenes Restelement eines solchen Schalungsbauteiles um 180° gedreht, auf ein anderes Schalungsbauteil aufgesteckt und damit weiter verwendet werden. Die Begriffe "obere" und "untere" für die erläuterten Flächen bedingen also nicht, daß diese Flächen stets oben oder unten gelegen sein müssen- Im Gegensatz zu den eingangs erläuterten vorbekannten Schalungsbauteilen wird mit der Erfindung vorteilhafterweise die Zahl der Steckverbindungen pro Flächeneinheit (bei gleicher Rasterteilung) verdoppelt, da zwischen den Vorsprüngen der einen Fläche Aussparungen für die Aufnahme von Vorsprüngen der anderen Fläche vorgesehen sind. Da erfindungsgemäß die Vorsprünge und Aussparungen einander gleich sind und ineinander passen, werden parallel zu der oberen bzw. unteren Fläche verlaufende Kräfte von den ineinander befindlichen Aussparungen und Vorsprüngen aufgenommen, ohne daß sich die Schalungsbauteile in Richtung dieser Kräfte zueinander verschieben können. Die Versetzung der Vorsprünge oder Aussparungen der einen (oberen) Fläche gegenüber den Vorsprüngen und Aussparungen der anderen (unteren) Fläche eines Schalungsbauteiles um eine Rasterteilung ergibt weitere Vorteile. Damit ist beim Aufeinanderstecken einer oberen Fläche und einer unteren Fläche zweier benachbarter Schalungsbauteile erreichbar, daß auch deren schmale Stirnseiten, die senkrecht zur oberen bzw. unteren Fläche verlaufen, miteinander fluchten. Dreht man aber eines der Schalungsbauteile um 180°, so daß seine obere Fläche mit der oberen Fläche des benachbarten Schalungsbauteiles zusammenzustecken ist (bzw. in der nächstfolgenden Reihe von Schalungsbauteilen sind diese mit zwei unteren Flächen zusammengesteckt), so ist gemäß der Erfindung eine ebenso einwandfreie Steckverbindung wie beim Zusammenstecken einer oberen Fläche und einer unteren Fläche gegeben, wobei die so zusammengesteckten Schalungsbauteile in ihrer Längsrichtung um eine halbe Rasterteilung versetzt sind. Dies bringt den vorstehend bereits erwähnten Vorteil, daß das Rastermaß bei T- und Eckverbindungen halbiert werden kann. Ja nach der Drehlage der miteinander verbundenen Schalungsbauteile können diese also um eine halbe oder eine ganze Rasterteilung, oder auch überhaupt nicht zueinander versetzt sein. Dies gibt auf der Baustelle die Möglichkeit, derartige Schalungsbauteile in verschiedene Anordnungen zueinander zu bringen. Insbesondere bei den bereits erwähnten T- und Eckverbindungen ist das vorgenannte Rastermaß von großer Bedeutung. Je kleiner man das Rastermaß wählen kann, umso mehr Möglichkeiten sind für das Planen und Erstellen eines Gebäudes gegeben, um unterschiedlichen, von dem Architekten vorgegebenen Maßen gerecht werden zu können. Die Erfindung ermöglicht also in dieser Hinsicht eine sehr große Flexibilität, was insbesondere für die angesprochenen Eckverbindungen gilt. Bei der eingangs genannten Vorveröffentlichung DE-GM 86 01 945.7 beträgt das Rastermaß 125 mm, ist also aus den vorgenannten Gründen viel zu grob. Beim Gegenstand von DE-GM 83 21 739 beträgt das Rastermaß zwar demgegenüber nur 25 mm, es kann jedoch nicht mehr verkleinert werden, da die Zapfen und die die Zapfen aufnehmenden Aussparungen bei einem noch kleineren Rastermaß in ihrem Durchmesser so weit verringert werden müssen, daß sie dann nicht mehr ausreichend stabil sind. Dagegen kann mit der Erfindung auch bei einem Rastermaß von 25 mm einerseits die gewünschte Stabilität erreicht werden, jedoch andererseits noch eine Versetzung auf das Rastermaß R/2 von 12,5 mm erreicht werden. Die bevorzugte, jedoch nicht ausschließliche Rasterteilung R nach der Erfindung ist 50 mm oder sogar 25 mm.To solve this problem, starting from the preamble of claim 1 cited at the beginning, it is provided that each of the two surfaces, ie both an upper surface and a lower surface of a formwork component, which enter into a plug connection during operation with a corresponding counter surface of another formwork component, with all mutually identical and mating projections and recesses located between the projections are provided, which fit into the identically formed recesses and projections of each of the mating surfaces of another formwork component to form the plug connection, and that the projections or recesses of one surface (upper surface) opposite the projections and recesses of the other surface (lower surface) of the formwork component are offset by a grid pitch. Thus, both on the upper surface and on the lower surface of the formwork components, projections with gaps are all arranged so that these gaps between the projections form recesses which serve to receive all the projections of another, above or below other formwork components, the Recesses of the latter formwork component take up all the projections of the former formwork component. The terms "upper surface" and "lower surface" have been chosen to define these two surfaces located on opposite sides of the formwork components in order to clarify the essence of the present invention in contrast to the prior art. In the prior art mentioned at the outset, either one (for example the upper surface) has only protrusions and the other (for example lower surface) has only recesses or there are (FR-PS 562 166) different protrusions and recesses provided on the upper and lower surfaces, which also only allow an upper surface of one stone to be inserted into one another and a lower surface of another stone. In contrast, both the upper surface and the lower surface are formed with the invention according to the characterizing part of claim 1 cited above. Thus, on the one hand, both an upper surface and a lower surface of such a formwork component can be plugged onto one another, but also such formwork components can be connected to one another by plugging together two upper surfaces or two lower surfaces. The side faces of the stacked formwork components are flush with each other in each of the plug connections described above. The two last-mentioned variants have the advantage over the assembly of an upper surface and a lower surface that the grid division is halved for T and corner connections. Since the height of the respective wall, wall or the like is almost never equal to a whole multiple of the height of the formwork components when creating a building, the formwork components of the first bottom or last top row must be shortened, ie cut off. The cut-off parts can no longer be used in the arrangement according to the explained prior art. In the case of formwork components according to the invention, however, these residues can be assembled with other formwork components after being rotated through 180 °, ie they can be reused. The resulting cost savings are considerable. The same applies to the construction of gable walls where the formwork components have to be cut according to the respective sloping roof. Here, too, an obliquely cut off residual element of such a formwork component can be rotated by 180 °, plugged onto another formwork component and thus be used further. The terms "upper" and "lower" for the surfaces explained do not mean that these surfaces must always be located above or below - in contrast to the ones at the beginning Known previously known formwork components are advantageously doubled with the invention, the number of plug connections per unit area (with the same grid division), since recesses are provided between the projections of one surface for receiving projections of the other surface. Since, according to the invention, the projections and recesses are identical to one another and fit into one another, forces running parallel to the upper or lower surface are absorbed by the recesses and projections located one inside the other, without the formwork components being able to shift towards one another in the direction of these forces. The offset of the projections or recesses of one (upper) surface compared to the projections and recesses of the other (lower) surface of a formwork component by a grid division gives further advantages. When an upper surface and a lower surface of two adjacent formwork components are plugged onto one another, it can thus be achieved that their narrow end faces, which run perpendicular to the upper and lower surface, are flush with one another. But if you turn one of the formwork components by 180 °, so that its upper surface is to be plugged together with the upper surface of the adjacent formwork component (or in the next row of formwork components, these are plugged together with two lower surfaces), then according to the invention is just as flawless Plug connection as given when plugging together an upper surface and a lower surface, the formwork components thus plugged together being offset by half a grid pitch in their longitudinal direction. This brings the advantage already mentioned above that the grid dimension for T and corner connections can be halved. Depending on the rotational position of the formwork components that are connected to one another, they can therefore be offset by half or an entire grid pitch, or not at all. On the construction site, this gives the opportunity to bring such formwork components together in different arrangements. Especially with the T and Corner connections, the aforementioned grid dimension is of great importance. The smaller the grid size can be selected, the more options there are for planning and building a building in order to be able to meet different dimensions specified by the architect. In this respect, the invention thus enables a very high degree of flexibility, which applies in particular to the corner connections mentioned. In the above-mentioned prior publication DE-GM 86 01 945.7, the grid size is 125 mm, so it is much too coarse for the reasons mentioned above. In contrast, the subject of DE-GM 83 21 739 the grid size is only 25 mm, but it can no longer be reduced, since the pin and the recesses accommodating the pin have to be reduced in their diameter so much that the grid size is even smaller then they are no longer sufficiently stable. On the other hand, the desired stability can be achieved with the invention even with a grid dimension of 25 mm, but on the other hand a displacement to the grid dimension R / 2 of 12.5 mm can be achieved. The preferred, but not exclusive, grid pitch R according to the invention is 50 mm or even 25 mm.

Die Merkmale des Anspruches 2 sind eine bevorzugte, weil besonders stabile Ausführung der Vorsprünge und Aussparungen.The features of claim 2 are a preferred, because particularly stable design of the projections and recesses.

Die Merkmale des Anspruches 3 sind ebenfalls nicht dem erläuterten Stand der Technik zu entnehmen. Hierbei sind auf der Strecke einer Rasterteilung R jeweils eine Aussparung und ein Vorsprung hintereinander vorgesehen und zwar sowohl in der Längsrichtung des Schalungsbauteiles als auch in dessen Querrichtung. Diese relativ große Anzahl ineinander eingreifender Aussparungen und Vorsprünge erhöht die Stabilität der Steckverbindung.The features of claim 3 are also not to be found in the explained prior art. In this case, a recess and a projection are provided one behind the other on the route of a grid division R, both in the longitudinal direction of the formwork component and in its transverse direction. This relatively large number of interlocking recesses and projections increases the stability of the plug connection.

Im Zusammenhang mit den Merkmalen des Anspruches 3 trägt die Steganordnung gemäß Anspruch 4 zur weiteren Stabilität solcher Steckverbindungen bei. Die o.g. T- und Eckverbindungen werden hierdurch nicht behindert. Zugleich wird hierdurch eine Abdichtung gegen das Hindurchtreten von flüssiger Beton- oder Zementmilch geschaffen, die sich bei einer aus solchen Schalungsbauteilen zusammengesetzten verlorenen Schalung zwischen zwei Schalungswänden befindet. Das Verhindern des Auslaufens von Beton- oder Zementmilch bewirkt ferner, daß keine Wärmebrücken entstehen. Die Merkmale des Anspruches 6 ergeben dabei den Vorteil, daß zwar im Innenbereich der miteinander verbundenen Flächen der Schalungsbauteile die vorgenannte Sperre gegeben ist, daß aber auf der oberen und unteren Fläche des Schalungsbauteiles zwischen den Vorsprüngen befindliche Schmutzreste, Wasser oder dergleichen ungehindert nach außen durch eine Bürste oder dergleichen entfernt werden können. Dies wäre nur mit großer Mühe, bzw. überhaupt nicht möglich, falls diese Flächen zwischen den Vorsprüngen zum jeweiligen Rand hin ebenfalls durch solche Stege begrenzt wären. Andererseits kann man aber solche Verunreinigungen, wie Sand, kleine Steine oder dergleichen nicht auf den Flächenteilen zwischen den Vorsprüngen belassen, da dann beim Aufstecken des nächsten Schalungsbauteiles dessen Vorsprünge auf diese Verunreinigungen treffen und daher nicht vollständig in die Betriebslage eingebracht werden könnten mit der Konsequenz, daß dann die entsprechenden Flächen der Schalungsbauteile nicht völlig bündig aufeinander liegen würden.In connection with the features of claim 3, the web arrangement according to claim 4 contributes to the further stability of such plug connections. The above T and corner connections are not hindered by this. At the same time, this creates a seal against the passage of liquid concrete or cement milk, which is located between two formwork walls in the case of lost formwork composed of such formwork components. Preventing the leakage of concrete or cement milk also means that no thermal bridges are created. The features of claim 6 give the advantage that the aforementioned lock is given in the inner region of the interconnected surfaces of the formwork components, but that dirt residues, water or the like located on the upper and lower surfaces of the formwork component between the projections unhindered to the outside by a Brush or the like can be removed. This would only be possible with great difficulty, or not at all, if these areas between the projections to the respective edge were also limited by such webs. On the other hand, however, such impurities, such as sand, small stones or the like, cannot be left on the surface parts between the projections, since then when the next formwork component is plugged on, the projections meet these impurities and therefore could not be completely introduced into the operating position with the consequence that that then the corresponding surfaces of the formwork components would not be completely flush with each other.

Die Erfindung betrifft ferner eine aus solchen Schalungsbauteilen zusammengesetzte verlorene Schalung, wobei von den Schalungsbauteilen gebildete Außen- und Innenwände über in die Schalungsbauteile eingelassene Metallverbinder voneinander distanziert und zueinander gehalten sind (Oberbegriff des Anspruches 7). Es ist ein Teil der Aufgabe der Erfindung zu ermöglichen, daß solche Schalungsbauteile bei Weiterverwendung der abgeschnittenen Teile halbiert werden können. In Weiterbildung dieses Aufgabenteiles soll nun dafür gesorgt werden, daß die diese verlorene Schalung bildenden Schalungsbauteile und Metallverbinder mit verhältnismäßig geringem Aufwand etwa auf halber Höhe der Schalungsbauteile voneinander getrennt werden können. Zur Lösung dieser Aufgabe ist ausgehend vom vorstehend zitierten Oberbegriff des Anspruches 7 vorgesehen, daß die Metallverbinder aus einer oberen und einer unteren Verbinderhälfte bestehen, die sich in der oberen bzw. unteren Hälfte der verlorenen Schalung befinden und nur über relativ dünne und schwache Trennbrücken miteinander verbunden sind. Hiermit sind die Metallverbinder und die von ihnen verbundenen Schalungsbauteile beider Wände der verlorenen Schalung leicht, z.B. durch eine Säge, voneinander trennbar. Andererseits aber sind die Metallverbinder bei Erstellung der verlorenen Schalung zunächst in sich einstückig, wodurch die Montagekosten entsprechend verringert werden. Es ist ersichtlich, daß die Merkmale dieses Anspruches 7 und die hierdurch erzielten Vorteile besonders in Kombination mit den Vorteilen der zuvor erläuterten Ansprüche einsetzbar sind, wonach aufgrund der Ausgestaltung der oberen Fläche und der unteren Fläche der Schalungsbauteile diese auseinander geschnitten und danach die hierdurch gebildeten Hälften für sich weiter verwendbar und zusammensteckbar sind. Wesentlich ist ferner, daß nach der Erfindung beim Halbieren der Schalungsbauteile nicht in sie eingeschäumte Verankerungen der Metallverbinder getrennt, bzw. durchschnitten werden müssen.The invention further relates to a lost formwork composed of such formwork components, the outer and inner walls formed by the formwork components being spaced apart and held to one another via metal connectors let into the formwork components (preamble of claim 7). It is part of the object of the invention to enable such formwork components to be cut in half when the cut parts are reused. In a further development of this part of the task, care should now be taken to ensure that the formwork components and metal connectors forming this lost formwork can be separated from one another with relatively little effort, approximately at half the height of the formwork components. To solve this problem, starting from the preamble of claim 7 cited above, it is provided that the metal connectors consist of an upper and a lower connector half, which are located in the upper and lower half of the lost formwork and are connected to one another only via relatively thin and weak separating bridges are. The metal connectors and the formwork components connected by them to both walls of the lost formwork can hereby be separated easily, for example by a saw. On the other hand, however, when the lost formwork is created, the metal connectors are initially in one piece, which reduces the assembly costs accordingly. It can be seen that the features of this claim 7 and the advantages achieved thereby can be used in particular in combination with the advantages of the claims explained above, after which, due to the design of the upper surface and the lower surface of the formwork components, these are cut apart and then the halves formed thereby can be used and plugged together. It is also essential that, according to the invention, when the formwork components are halved, the anchoring of the metal connectors which is not foamed into them has to be separated or cut through.

Die Merkmale des Anspruches 8 ergeben zum einen relativ dünne, leicht auftrennbare Trennbrücken und zum anderen genügend steife Verbindungsstreben der Schalungsbauteile beider Schalungswände. Außerdem wird hierdurch innerhalb des quadratischen oder rechteckigen Mittelrahmen genügend freier Raum für die Aufnahme des Betons oder Zementes und etwaiger Armierungen geschaffen. Die Trennbrücken sind vom Material der Schalungsbauteile, bevorzugt einem Hartchaumstoff, nicht umgeben, so daß sie den Querschnitt der Schalungsbauteile nicht schwächen. Es sind also nur relativ dünne Metallstäbe zu durchtrennen. Ferner ergibt sich hierdurch der Vorteil, daß das Durchtrennen der Trennbrücken mit einer Metalltrennscheibe, einer Säge, einer Ausklinkschere oder dergleichen außerhalb des Materials des Schalungsbauteiles erfolgt, dieses also nicht beschädigt. Beim Durchsägen von Metall entsteht nämlich Hitze, welche den Hartschaumstoff des Schalungsbauteiles zum Schmelzen bringen könnte.The features of claim 8 result on the one hand relatively thin, easily separable dividers and on the other hand sufficiently rigid connecting struts of the formwork components of both formwork walls. It also makes enough free space within the square or rectangular center frame Space was created to accommodate the concrete or cement and any reinforcements. The separating bridges are not surrounded by the material of the formwork components, preferably a hard foam, so that they do not weaken the cross section of the formwork components. It is therefore only necessary to cut relatively thin metal rods. This also has the advantage that the separation bridges are cut with a metal cutting disc, a saw, a notching shear or the like outside the material of the formwork component, so that it does not damage it. When sawing through metal, heat is generated which could cause the rigid foam of the formwork component to melt.

Die Seiten des Mittelrahmens können mit ihren äußeren Kanten Anlagen für die Schalungsbauteile bilden. Fluchtend mit den genannten Verbindungsstreben erstreckt sich von diesen äußeren Kanten beidseitig je eine Verlängerung in das jeweilige Schalungsbauteil hinein, wobei die jeweilige Verlängerung die jeweilige Verankerung trägt (Anspruch 9). Die Verankerungen können durch Umbiegen oder Umfalzen der Enden von Verlängerungen der Verbindungsstreben gebildet sein (Anspruch 10) Hiermit wird die Verankerung konstruktiv einfach und vorteilhaft ausgebildet, wobei sie ein etwaiges Halbieren des Schalungsbauteiles nicht behindert.The outer edges of the sides of the middle frame can form attachments for the formwork components. In alignment with the connecting struts mentioned, an extension extends from these outer edges on both sides into the respective formwork component, the respective extension carrying the respective anchoring (claim 9). The anchors can be formed by bending or folding the ends of extensions of the connecting struts (claim 10). This makes the anchoring structurally simple and advantageous, while it does not hinder a possible halving of the formwork component.

Ferner kann gemäß Anspruch 11 vorgesehen sein, daß in der fertigen Schalung quer zur Längsrichtung der Schalungsbauteile verlaufende, ebenfalls bevorzugt aus Hartschaumstoff bestehende, Querverbinder vorgesehen und an ihrer oberen und ihrer unteren Fläche ebenso wie die obere Fläche und die untere Fläche der Schalungsbauteile ausgebildet sind. Damit wird die Erfindung auch auf derartige Querverbinder ausgedehnt.Furthermore, it can be provided according to claim 11 that in the finished formwork transverse to the longitudinal direction of the formwork components, also preferably made of rigid foam, cross connectors are provided and are formed on their upper and lower surfaces as well as the upper surface and the lower surface of the formwork components. This extends the invention to such cross connectors.

Mit den Merkmalen des Anspruches 12 kann durch Umdrehen des Querverbinders erreicht werden, daß an der betreffenden Seite etwas Spielraum zum Einsetzen von Fenster und Türen, gegebenenfalls auch zum Ausgleich von Fertigungsungenauigkeiten, besteht.With the features of claim 12 can be achieved by turning the cross connector that there is some leeway on the relevant side for inserting windows and doors, possibly also to compensate for manufacturing inaccuracies.

Die Schalungsbauteile 1 bilden in einer verlorenen Schalung die beiden Außenwände 2, indem eine entsprechende Anzahl von Schalungsbauteilen 1 übereinander und nebeneinander vorgesehen wird. Der Raum 3 zwischen den beiden Wänden 2 wird mit Beton oder Zement ausgefüllt. Die Distanzierung beider Wände 2 und gleichzeitig der Halt ihrer Schalungsbauteile aneinander erfolgt mit Hilfe von Metallverbindern 4. Die Schalungsbauteile 1 und die nachstehend noch zu erläuternden Querschalungsteile oder -verbinder 5 bestehen bevorzugt aus einem harten geschäumten Kunststoff, während die Metallverbinder 4 bevorzugt aus Stahlblech hergestellt sind.The formwork components 1 form the two outer walls 2 in a lost formwork by providing a corresponding number of formwork components 1 above and next to one another. The space 3 between the two walls 2 is filled with concrete or cement. The spacing of the two walls 2 and at the same time the holding of their formwork components to one another takes place with the aid of metal connectors 4. The formwork components 1 and the cross-formwork parts or connectors 5 to be explained below preferably consist of a hard foamed plastic, while the metal connectors 4 are preferably made of sheet steel .

Die Steckverbindung der Schalungsbauteile erfolgt durch Vorsprünge 6 und dazwischen befindliche Aussparungen 7, die sich in gleicher Größe und Rastermaß auf beiden Flächen 8, 9 der Schalungsbauteile 2 befinden. Dabei ist die eine Fläche eines Schalungsbauteiles als obere Fläche 8 und die ihr gegenüberliegende andere Fläche als untere Fläche 9 definiert (siehe Fig. 1). Hierbei passen die Vorsprünge 6 der unteren Fläche 9 in die Aussparungen 7 der oberen Fläche 8 und ebenso die Vorsprünge 6 der oberen Fläche 8 in die Aussparungen 7 der unteren Fläche 9. Hiermit sind die eingangs erläuterten Steckmöglichkeiten gegeben, wobei die Aussparungen und Vorsprünge so passend bemessen sind, daß die Schalungsbauteile nicht durch in Längsrichtung der Flächen 8, 9 verlaufende Kräfte zueinander verlagert sein können. Die Vorsprünge 6 und Aussparungen 7 bilden sowohl in der Längsrichtung 11 als auch in der Querrichtung 11' der Schalungsbauteile bzw. der hiermit hergestellten Schalung jeweils ein Rastermaß, wobei sowohl in der Längsrichtung 11 als auch in der Querrichtung 11' abwechselnd ein Vorsprung und eine Aussparung hintereinander angeordnet sind. Es sind auch Querverbindungen entweder durch die Schalungsbauteile oder aber durch die Querverbinder 5 möglich, welche die gleiche Höhe wie die Schalungsbauteile haben.The formwork components are plugged in by means of projections 6 and recesses 7 located between them, which are of the same size and pitch on both surfaces 8, 9 of the formwork components 2. One surface of a formwork component is defined as the upper surface 8 and the other surface opposite it is defined as the lower surface 9 (see FIG. 1). Here, the projections 6 of the lower surface 9 fit into the recesses 7 of the upper surface 8 and likewise the projections 6 of the upper surface 8 into the recesses 7 of the lower surface 9. This provides the plug options explained at the outset, the recesses and projections being so suitable are dimensioned such that the formwork components cannot be displaced from one another by forces running in the longitudinal direction of the surfaces 8, 9. The projections 6 and recesses 7 each form a grid dimension both in the longitudinal direction 11 and in the transverse direction 11 'of the formwork components or the formwork produced therewith, both in the longitudinal direction 11 and in the transverse direction 11 'alternately a projection and a recess are arranged one behind the other. Cross connections are also possible either through the formwork components or through the cross connector 5, which have the same height as the formwork components.

In der dargestellten bevorzugten Ausführungsform sind die Vorsprünge und Aussparungen der einen, oberen Fläche 8 gegenüber denen der anderen unteren Fläche 9 um eine Rasterteilung R versetzt. Dies ist daraus zu entnehmen, daß den in Fig. 1 jeweils links unten dargestellten Vorsprüngen 6 der unteren Fläche 9 jeweils in Fig. 1 links oben Aussparungen 7 der oberen Fläche 8 gegenüberliegen. Dies bedeutet, daß beim Aufeinanderstecken einer oberen Fläche mit einer unteren Fläche die schmalen Stirnseiten 10 der so miteinander verbundenen Schalungsbauteile zueinander bündig sein können, oder um eine ganze Rasterteilung R zueinander versetzt sind. Werden dagegen Schalungsbauteile mit ihren oberen Flächen oder mit ihren unteren Flächen zu einer Steckverbindung gebracht, so sind dann diese Schalungsbauteile um die Hälfte des Rastermaßes R zueinander versetzt (siehe hierzu auch die Erläuterungen der Fig. 6 bis 8).In the preferred embodiment shown, the projections and recesses of one upper surface 8 are offset by a raster pitch R from those of the other lower surface 9. This can be seen from the fact that the projections 6 of the lower surface 9, which are shown at the bottom left in FIG. 1, are opposite recesses 7 of the upper surface 8 at the top left in FIG. 1. This means that when an upper surface with a lower surface is plugged onto one another, the narrow end faces 10 of the formwork components connected to one another can be flush with one another, or can be offset by an entire grid pitch R. If, on the other hand, formwork components are brought to a plug connection with their upper surfaces or with their lower surfaces, then these formwork components are offset from one another by half the grid dimension R (see also the explanations in FIGS. 6 to 8).

Auf beiden Flächen 8, 9 sind zwischen den Vorsprüngen 6 Stege 12 vorgesehen, die sich von der jeweiligen Fläche 8 bzw. 9 her in der Richtung der Vorsprünge 6 bis zu deren halben Höhe hin erstrecken. Diese Stege sind so angeordnet, daß sie in jeder der möglichen Steckverbindungen zwischen den Schalungsbauteilen aufeinanderliegen und damit eine Dichtung oder Trennwand gegen das Austreten von Beton oder Zement aus dem Raum 3 nach außen bilden. Dabei empfiehlt es sich, die Stege 12 nur im Innenbereich der Flächen 8, 9 anzuordnen (siehe insbes. Fig. 2), so daß die Aussparungen 7 außenseitig, d.h. zu den Seitenflächen 13 der Schalungsbauteile hin, nicht durch solche Stege abgegrenzt sind.On both surfaces 8, 9, webs 12 are provided between the projections 6, which extend from the respective surface 8 or 9 in the direction of the projections 6 up to half their height. These webs are arranged so that they lie one on top of the other in each of the possible plug connections between the formwork components and thus form a seal or partition wall against the escape of concrete or cement from the room 3 to the outside. It is advisable to arrange the webs 12 only in the inner region of the surfaces 8, 9 (see in particular FIG. 2), so that the recesses 7 are not delimited by such webs on the outside, ie towards the side surfaces 13 of the formwork components.

Damit können auf den Aussparungen 7 befindliche Verunreinigungen problemlos durch eine Bürste oder dergleichen entfernt werden. Wie das vorliegende Ausführungsbeispiel zeigt (siehe insbesondere Fig. 2) ist jeder der bevorzugt quadratischen Vorsprünge an drei seiner Eckkanten 6' über einen Steg 12 mit der gegenüberliegenden Eckkante 6' des benachbarten Vorsprunges der nächsten, aus Vorsprüngen und Aussparungen bestehenden Reihe verbunden. Die Stege 12 verlaufen also im Winkel von etwa 45° zu den vorgenannten Reihen und verbinden die einander zugewandten, d.h. sich nahe gegenüberliegenden Eckkanten 6'. Dabei ist jedoch die obere Hälfte der Vorsprünge von Stegen 12 frei (siehe oben). Die Eckkanten 6' können abgephast oder abgerundet sein. Damit passen die entsprechend an ihren Eckkanten abgephasten oder abgerundeten Vorsprünge eines anderen Schalungsbauteiles in die entsprechend geformten, z.B. etwa quadratischen Aussparungen 7, da sie dann mit ihren Abphasungen zwischen die Seitenflächen der Stege 12 passen und an deren Seitenflächen anliegen. Dagegen ist zwischen den vierten Seitenkanten der Vorsprünge kein Steg vorhanden, wobei diese vierten Seitenkanten so gelegen sind, daß das o.g. Entfernen von Verunreinigungen möglich ist. Zur leichteren Erkennbarkeit sind in den Figuren 2, 3 die Aussparungen 7 grob schraffiert und die Stege 12 fein schraffiert, während die Vorsprünge 6 keine Schraffur aufweisen. Zur Erleichterung des Einsteckens können ferner die Vorsprünge an den Seitenrändern ihrer oberen Stirnflächen ebenfalls mit Abphasungen oder Abrundungen 6" versehen sein.Contamination located on the recesses 7 can thus be easily removed by a brush or the like. As the present exemplary embodiment shows (see in particular FIG. 2), each of the preferably square projections on three of its corner edges 6 'is connected via a web 12 to the opposite corner edge 6' of the adjacent projection of the next row consisting of projections and recesses. The webs 12 thus run at an angle of approximately 45 ° to the aforementioned rows and connect the mutually facing, i.e. opposite corner edges 6 '. However, the upper half of the projections is free of webs 12 (see above). The corner edges 6 'can be chamfered or rounded. Thus, the correspondingly bevelled or rounded protrusions of another formwork component on their corner edges fit into the correspondingly shaped, e.g. approximately square recesses 7, since they then fit with their bevels between the side surfaces of the webs 12 and rest on their side surfaces. In contrast, there is no web between the fourth side edges of the projections, these fourth side edges being located in such a way that the above-mentioned. Removal of contaminants is possible. For easier identification, the cutouts 7 are roughly hatched in FIGS. 2, 3 and the webs 12 are hatched finely, while the projections 6 have no hatching. To facilitate insertion, the projections on the side edges of their upper end faces can also be provided with chamfers or roundings 6 ″.

Die Vorsprünge 6 der oberen Fläche 8 können Markierungen oder dergleichen aufweisen, so daß sie bei der Montage sofort von den Vorsprüngen 25 der unteren Fläche 9 unterscheidbar sind. Damit werden Verwechslungen zwischen der oberen und der unteren Fläche vermieden. Die Ausführung der Vorsprünge, z.B. Zapfen ist nicht auf die dargestellte quadratische Form beschränkt. Es muß lediglich gesichert sein, daß die Schalungsbauteile sowohl nach Drehen um 180°, aber auch nach Drehen um 90° (Bildung von Querwänden) im Raster zueinander steckbar passen.The projections 6 of the upper surface 8 can have markings or the like so that they can be immediately distinguished from the projections 25 of the lower surface 9 during assembly. This prevents confusion between the top and bottom surfaces. The design of the projections, for example pins is not shown limited square shape. It only has to be ensured that the formwork components can be plugged into one another in a grid both after turning through 180 ° and after turning through 90 ° (formation of transverse walls).

Die Metallverbinder 4 sind in ihrem Aufbau den Fig. 4, 5 zu entnehmen. Sie bestehen aus zwei Verbinderhälften, die sich oberhalb bzw. unterhalb der strichpunktiert eingezeichneten Mittellinie 14 befinden. Zwischen ihnen besteht lediglich eine jeweils dünne Trennstelle 15, die im Falle des Aufteilens der Schalungsbauteile in entsprechende obere und untere Hälften leicht durchgeschnitten werden können. Hierzu empfiehlt sich die dargestellte und bevorzugte Ausführungsform der Metallverbinder in Form eines rechteckigen oder quadratischen Mittelrahmens, bestehend aus zwei einander gegenuberliegenden Seiten 16, welche die Trennstellen 15 aufweisen und zwei Verbindungsstreben 17, die in Verlängerungen 19 mit Verankerungen 18 auslaufen. Die Verankerungen 18 befinden sich im Material der Schalungsbauteile und sind durch Umbiegen und Umfalzen der Enden der sie tragenden Verlängerungen 19 geschaffen. Innerhalb des aus den Teilen 16, 17 gebildeten Rechteckes befindet sich ein genügend großer Hohlraum 20 für das Hindurchtreten von Beton, Zement und gegebenenfalls von Armierungen. Die Metallverbinder 4 sind nicht so hoch wie die Schalungsbauteile, so daß über und unter ihnen genügend Platz für Beton oder Zement besteht.The structure of the metal connectors 4 can be seen in FIGS. 4, 5. They consist of two connector halves, which are located above and below the dash-dotted center line 14. Between them there is only a thin separation point 15, which can be easily cut through if the formwork components are divided into corresponding upper and lower halves. For this purpose, the illustrated and preferred embodiment of the metal connector in the form of a rectangular or square central frame is recommended, consisting of two mutually opposite sides 16, which have the separation points 15 and two connecting struts 17, which end in extensions 19 with anchors 18. The anchors 18 are in the material of the formwork components and are created by bending and folding the ends of the extensions 19 carrying them. Within the rectangle formed from the parts 16, 17 there is a sufficiently large cavity 20 for the passage of concrete, cement and possibly reinforcements. The metal connectors 4 are not as high as the formwork components, so that there is enough space for concrete or cement above and below them.

Insbesondere Fig. 2 zeigt, daß zwischen den Metallverbindern 4 in den Seitenwänden 13 der Schalungsbauteile vertikal verlaufende Längsnuten 21 für die Aufnahme entsprechender Vorsprünge 22 der Querverbinder 5 vorgesehen sein können. Hierdurch wird eine schwalbenschwanzartige Nut- und Federverbindung geschaffen, die insbesondere der Aufnahme von Querverbindern in Form von Mauer- Endabschlüssen dient. Fig. 3 zeigt, daß diese Querverbinder 5 in die Längsnuten 21 der Innenseiten der Schalungsbauteile mit Hinterschneidung passende Längsfedern 22 aufweisen. Dabei kann der Abstand der Längsfedern zu einer Wandseite 23 des Querverbinders kleiner, z.B. um 5 mm kleiner sein als der Abstand des anderen Querverbinders von der anderen Wandseite 24. Es empfiehlt sich, die Längsnuten 21 in einem Schalungsbereich vorzusehen, der zwischen den Metallverbindern gelegen ist.2 shows in particular that longitudinal grooves 21 which run vertically between the metal connectors 4 in the side walls 13 of the formwork components can be provided for receiving corresponding projections 22 of the cross connectors 5. This creates a dovetail tongue and groove connection, which is used in particular to accommodate cross connectors in the form of wall end closures. Fig. 3 shows that these cross connector 5 in the longitudinal grooves 21 of the Have matching longitudinal springs 22 on the inside of the formwork components with an undercut. The distance of the longitudinal springs to one wall side 23 of the cross connector may be smaller, for example 5 mm smaller than the distance of the other cross connector from the other wall side 24. It is advisable to provide the longitudinal grooves 21 in a formwork area which is located between the metal connectors .

Fig. 6 zeigt schematisch zwei Schalungsbauteile 1, wobei die untere Fläche 9 des oberen Schalungsbauteiles mit der oberen Fläche 8 des unteren Schalungsbauteiles zusammengesteckt ist. Die Versetzung des oberen Schalungsbauteiles zum unteren Schalungsbauteil beträgt 1 Rastermaß R von z.B. 50 mm. Gemäß der Zeichnung zählt ein Rastermaß von einer Seitenkante eines Vorsprunges (oder Aussparung) bis zur entsprechenden Seitenkante des nächsten Vorsprunges (oder der nächsten Aussparung) und zwar sowohl in Längsrichtung der Schalungsbauteile als auch quer dazu. Falls erwünscht, können die Schalungsbauteile aber auch so aufeinander gesetzt werden, daß ihre in der Zeichnung senkrechten schmalen Stirnseiten jeweils miteinander bündig sind.6 schematically shows two formwork components 1, the lower surface 9 of the upper formwork component being plugged together with the upper surface 8 of the lower formwork component. The displacement of the upper formwork component to the lower formwork component is 1 grid dimension R of e.g. 50 mm. According to the drawing, a grid dimension counts from one side edge of a projection (or recess) to the corresponding side edge of the next projection (or the next recess), both in the longitudinal direction of the formwork components and transversely thereto. If desired, the formwork components can also be placed on top of each other in such a way that their narrow end faces, which are vertical in the drawing, are each flush with one another.

Fig. 7 zeigt die gleichen Schalungsbauteile, wobei aber der obere Schalungsbauteil 1 umgedreht ist, so daß seine obere Fläche 8 unten liegt und mit der oben liegenden oberen Fläche 8 des unteren Schalungsbauteiles zusammengesteckt ist. Damit kann die Versetzung der Schalungsbauteile zueinander gegenüber der Anordnung nach Fig. 6 um das halbe Rastermaß R/2 auf das halbe Rastermaß R/2, d.h. im Beispiel auf 25 mm verringert werden. Man kann natürlich auch umgekehrt von der eingangs bereits erwähnten Anordnung ausgehen, bei der zwei Schalungsbauteile so aufeinander gesteckt sind, daß ihre schmalen Stirnseiten bündig sind (dies ergäbe sich beispielsweise, wenn man in der Anordnung nach Fig. 6 den oberen Schalungsbauteil um eine Rasterteilung nach links versetzt). Von einer solche, bündigen Anordnung her kann ebenfalls durch ein Umdrehen eines der Schalungsbauteile und anschließendes Zusammenstecken dieser beiden Schalungsbauteile eine Stecklage mit einer Versetzung im halben Rastermaß R/2 erreicht werden, wie sie in Fig. 7 dargestellt ist. Man kann aber auch von einem kleineren Rastermaß, z.B. R gleich 25 mm ausgehen, so daß das halbe Rastermaß R/2 gleich 12,5 mm ist. Das Rastermaß R verteilt sich jeweils hälftig auf eine Aussparung und auf einen Vorsprung.Fig. 7 shows the same formwork components, but the upper formwork component 1 is turned over so that its upper surface 8 is at the bottom and is plugged together with the upper surface 8 of the lower formwork component located at the top. The offset of the formwork components relative to the arrangement according to FIG. 6 can thus be reduced by half the grid dimension R / 2 to half the grid dimension R / 2, ie to 25 mm in the example. Conversely, one can of course also start from the arrangement already mentioned at the beginning, in which two formwork components are placed one on top of the other in such a way that their narrow end faces are flush (this would result, for example, if the upper formwork component in the arrangement according to FIG Left offset). From such a flush arrangement, a plug-in position with an offset of half the grid dimension R / 2 can also be achieved by turning one of the formwork components and then plugging these two formwork components together, as is shown in FIG. 7. However, one can also assume a smaller grid dimension, for example R equal to 25 mm, so that half the grid dimension R / 2 is 12.5 mm. The grid dimension R is divided equally into a recess and a projection.

Man hat somit beim Zusammensetzen der Bauteile verschiedene Variationsmöglichkeiten. Insbesondere gilt das auch für die Herstellung von Eckverbindungen oder sogenannten T-Verbindungen der Schalungsbauteile. Man kann dabei gewissermaßen "um die Ecke herumstecken".There are thus various possible variations when assembling the components. In particular, this also applies to the production of corner connections or so-called T-connections of the formwork components. You can, so to speak, "stick around the corner".

Fig. 8 zeigt schematisch mehrere volle Schalungsbauteile 1, auf deren oberen Fläche 8 jeweils zwecks Bildung einer Schrägmauer abgeschrägte Schalungsbauteile 1' aufgesetzt werden können. Dabei kann der abgeschnittene Schalungsbauteil 1" aufgrund seiner Formgebung weiter verwendet werden, z.B. im vorliegenden Ausführungsbeispiel für den rechts gelegenen abgeschrägten Schalungsbauteil 1'. Hierdurch kann erheblich an Material der Schalungsbauteile gespart werden.Fig. 8 shows schematically several full formwork components 1, on the upper surface 8 of which in each case beveled formwork components 1 'can be placed to form an inclined wall. The cut formwork component 1 "can be used further due to its shape, e.g. in the present exemplary embodiment for the beveled formwork component 1 'located on the right. In this way, material of the formwork components can be saved considerably.
