Description

Die Erfindung betrifft ein Schalungselement gemäß Oberbegriff des Anspruches 1.The invention relates to a formwork element according to the preamble of claim 1.

Derartige Schalungselemente werden zur Herstellung von sogenannten Mantelbetonwänden verwendet. Zu diesem Zweck werden die einzelnen Schalungselemente aneinandergereiht und Lage für Lage übereinandergestapelt. Die Kanten der Schalungselemente weisen in der Regel Vorsprünge und Vertiefungen auf, die als Verbindungselemente wirken und beim Aufeinanderstapeln die exakte Positionierung ohne zusätzliche Hilfsmittel erlauben.Formwork elements of this type are used for the production of so-called shell concrete walls. For this purpose, the individual formwork elements are strung together and stacked on top of each other. The edges of the formwork elements generally have projections and depressions which act as connecting elements and, when stacked on top of one another, allow exact positioning without additional aids.

Die Schalungselemente sind in ihrem Inneren im wesentlichen hohl, wobei die jeweils gegenüberliegend angeordneten Seitenplatten durch dazwischenliegende Verbindungselemente im Abstand gehalten werden. Die Form der Verbindungselemente ist so gewählt, daß die Hohlräume der aufeinandergestapelten Schalungselemente miteinander in Verbindung stehen.The formwork elements are essentially hollow in their interior, the side plates arranged opposite each other being kept at a distance by connecting elements located between them. The shape of the fasteners is chosen so that the cavities of the stacked formwork elements are connected.

In den auf diese Weise entstehenden Hohlraum wird Beton gegossen. Nach dem Abbinden bildet der Beton zusammen mit den Schalungselementen die Mantelbetonwand. Im Gegensatz zu traditionellen Schalungen verbleibt die Schalung im Bauwerk und stellt somit eine verlorene Schalung dar.Concrete is poured into the cavity created in this way. After setting, the concrete forms the shell concrete wall together with the formwork elements. In contrast to traditional formwork, the formwork remains in the building and thus represents lost formwork.

Die Außenseiten der Seitenplatten der Schalungselemente bilden die entsprechenden Wandflächen, auf die z.B. unmittelbar der Putz aufgetragen werden kann. Auch andere Arten von Wandbelag, wie beispielsweise Tapeten oder Paneele können unmittelbar auf den Seitenplatten angebracht werden.The outer sides of the side panels of the formwork elements form the corresponding wall surfaces on which e.g. the plaster can be applied immediately. Other types of wall covering, such as wallpaper or panels, can also be attached directly to the side panels.

Derartige Schalungselemente wurden häufig in der Form von Leichtbetonbausteinen ausgeführt, jedoch haben sich insbesondere Schalungselemente aus Hartkunststoffen bewährt, die neben ihrer ursprünglichen Funktion als Schalung zusätzlich ein hohes Maß an Wärmeisolation gewährleisten. Dieser zusätzliche Effekt der Wärmedämmung verhalf den Schalungselementen aus Hartkunststoff zu einer weiten Verbreitung.Formwork elements of this type were frequently designed in the form of lightweight concrete building blocks, however, formwork elements made of hard plastics have proven themselves in particular, which in addition to their original function as formwork also ensure a high degree of thermal insulation. This additional effect of thermal insulation made the formwork elements made of hard plastic widely used.

In vielen Fällen reicht jedoch die mit derartigen Schalungselementen hergestellte Mantelbetonwand allein noch nicht aus, um eine ausreichende Schallisolierung zu erzielen. Dann ist es erforderlich, die Mantelbetonwand mit einer zusätzlichen Schallschutzverkleidung zu versehen. Dies kann beispielsweise durch das Anbringen von Dämmplatten an der fertiggestellten Mantelbetonwand geschehen.In many cases, however, the mantle concrete wall made with such formwork elements alone is not sufficient to achieve adequate sound insulation. Then it is necessary to provide the cladding wall with additional soundproofing. This can be done, for example, by attaching insulation panels to the finished concrete wall.

Nachteilig hierbei ist, daß ein zusätzlicher Arbeitsgang erforderlich ist, um die Schallschutzverkleidung anzubringen. Darüber hinaus eignen sich viele der Schalldämmplatten nicht zur darauf folgenden unmittelbaren Anbringung des endgültigen Wandbelages, vielmehr muß eine weitere Schicht aufgebracht werden, die den endgültigen Wandbelag trägt.The disadvantage here is that an additional operation is required to attach the soundproofing panel. Many of the soundproofing panels are also suitable not for the subsequent immediate attachment of the final wall covering, rather a further layer must be applied which supports the final wall covering.

Aus der DE-A-22 42 460, von der die Erfindung ausgeht, ist ein Schalungselement für die Mantelbetonweise bekannt, bei dem zwei im Abstand und parallel zueinander angeordnete Seitenplatten vorgesehen sind, die untereinander mit Verbindungselementen verbunden sind. Auf eine der beiden Seitenplatten, die aus geschäumtem Hartkunststoff besteht, ist eine Dämmplatte aus schalldämmendem Faserwerkstoff aufgenagelt.From DE-A-22 42 460, from which the invention is based, a formwork element for the shell-concrete method is known, in which two spaced and parallel side plates are provided, which are interconnected with connecting elements. An insulation panel made of sound-absorbing fiber material is nailed onto one of the two side panels, which is made of foamed hard plastic.

Der vorliegenden Erfindung lag deshalb das Problem zugrunde, ein Schalungselement der eingangs genannten Art zur Verfügung zu stellen, das unter Beibehaltung der bisher erzielten Vorteile, insbesondere der einfachen Handhabung sowie der guten Wärmeisolationseigenschaft, eine zusätzliche Schalldämmung ermöglicht, ohne den Aufwand bei der Erstellung der Mantelbetonwand zu erhöhen.The present invention was therefore based on the problem of providing a formwork element of the type mentioned at the outset which, while maintaining the advantages achieved to date, in particular the simple handling and the good thermal insulation property, enables additional sound insulation without the expense of creating the shell concrete wall to increase.

Erfindungsgemäß wird dieses Problem bei einem gattungsgemäßen Schalungselement mit den Merkmalen des Kennzeichens des Anspruches 1 gelöst.According to the invention, this problem is solved in a generic formwork element with the features of the characterizing part of claim 1.

Vorteilhafte Ausgestaltungen des erfindungsgemäßen Schalungselementes ergeben sich aus den Merkmalen der Unteransprüche.Advantageous embodiments of the formwork element according to the invention result from the features of the subclaims.

Der Erfindung liegt die Idee zugrunde, die Schalungselemente innenseitig, d.h. an der dem Hohlraum zugewandten Seite der Seitenplatten mit einer weiteren Dämmplatte zu versehen, die die gewünschten Eigenschaften aufweist. Hierdurch ist es möglich, die gewohnte Außenstruktur der Schalungselemente beizubehalten, ohne daß zusätzliche Maßnahmen zur nachträglichen Schalldämmung erforderlich sind. Die Herstellung der Mantelbetonwand erfolgt in der gleichen Art und Weise, wie dies bisher bei den Schalungselementen nach dem Stand der Technik möglich war. Besondere Vorkehrungen oder Maßnahmen sind nicht nötig, so daß die Herstellung der Schalung wie bisher auch von angelernten Kräften erstellt werden kann.The invention is based on the idea of providing the formwork elements on the inside, ie on the side of the side panels facing the cavity, with a further insulation panel which has the desired properties. This makes it possible to maintain the usual external structure of the formwork elements without additional measures for subsequent sound insulation being required. The shell concrete wall is produced in the same way as was previously possible with the formwork elements according to the prior art. Special precautions or measures are not necessary, so that the manufacture of the formwork can be carried out by trained personnel as before.

Die Erfindung wird näher anhand des in den Figuren 1 bis 3 dargestellten Ausführungsbeispieles nachstehend erläutert. Es zeigen als Prinzipskizzen :

The invention is explained in more detail below with reference to the embodiment shown in Figures 1 to 3. The basic diagrams show:
Figure 1

Figure 2
the formwork element in front view,
Figure 3
a shell concrete wall with several formwork elements as lost formwork.

Aus den Figuren 1 und 2 ergibt sich der prinzipielle Aufbau des erfindungsgemäßen Schalungselementes. Es besteht im wesentlichen aus zwei im Abstand und parallel zueinander angeordneten Seitenplatten 1, an deren Innenseiten jeweils eine Dämmplatte 3 angeordnet ist. Zwischen den gegenüberliegenden Dämmplatten 3 und damit zwischen den Seitenplatten 1 sind Verbindungselemente 2 angeordnet. Die Verbindungselemente 2 dienen einerseits als Abstandshalter für die beiden Seitenplatten 1 einschließlich der an ihnen angebrachten Dämmplatten 3, andererseits sind sie so befestigt, daß sie dem gesamten Schalungselement eine ausreichende Eigenstabilität geben. Dies wird beispielsweise dadurch erreicht, daß eine Vielzahl derartiger Verbindungselemente 2 sowohl in Längsrichtung als auch übereinander angeordnet sind. Die Anordnung als solche ist im wesentlichen frei wählbar, entscheidend ist nur, daß die gewünschte Eigenstabilität erreicht wird. Im dargestellten Beispiel sind drei übereinanderliegende Reihen von jeweils fünf Verbindungselementen vorgesehen, wobei jeweils drei Verbindungselemente fluchtend übereinanderliegen. Ebenso können die Verbindungselemente sowohl seitlich als auch höhenversetzt angeordnet werden, wenn dies gewünscht wird.The basic structure of the formwork element according to the invention results from FIGS. 1 and 2. It essentially consists of two spaced apart and parallel side panels 1, on the inner sides of which an insulating panel 3 is arranged. Connecting elements 2 are arranged between the opposite insulation panels 3 and thus between the side panels 1. The connecting elements 2 serve on the one hand as a spacer for the two side panels 1 including the insulation panels 3 attached to them, on the other hand they are fastened in such a way that they give the entire formwork element sufficient inherent stability. This is achieved, for example, in that a large number of such connecting elements 2 are arranged both in the longitudinal direction and one above the other. The arrangement as such is essentially freely selectable, the only important thing is that the desired inherent stability is achieved. In the example shown, three rows of five connecting elements, one on top of the other, are provided, three connecting elements lying one above the other in alignment. Likewise, the connecting elements can be arranged laterally as well as offset in height if this is desired.

Im dargestellten Ausführungsbeispiel sind an jeder der beiden Seitenplatten 1 jeweils eine Dämmplatte 3 innenseitig angebracht. Dies ist jedoch nicht zwingend erforderlich, auch sind Konfigurationen mit nur einer Dämmplatte 3 an einer der beiden Seitenplatten 1 möglich. Diese kann bei entsprechender Wahl der Dicke die gleiche Dämmwirkung aufweisen wie die Konfiguration mit zwei gegenüberliegend angeordneten Dämmplatten 3. Der Vorteil der beidseitigen Anbringung der Dämmplatten 3 liegt darin, daß das Schalungselement symmetrisch aufgebaut ist. Beim Aneinander-und Aufeinanderschichten der Schalungselemente muß nicht darauf geachtet werden, auf welcher Seite sich jeweils die Dämmplatte 3 befindet, um die gewünschte Zuordnung zu einer der beiden Seiten zu gewährleisten.In the illustrated embodiment, an insulation panel 3 is attached to the inside of each of the two side panels 1. However, this is not absolutely necessary, and configurations with only one insulation panel 3 on one of the two side panels 1 are also possible. If the thickness is selected accordingly, this can have the same insulation effect as the configuration with two insulation panels 3 arranged opposite one another. The advantage of the insulation panels 3 being attached on both sides is that the formwork element is constructed symmetrically. When layering the formwork elements together and on top of one another, it is not necessary to pay attention to which side the insulation board 3 is located in order to ensure the desired assignment to one of the two sides.

Die Dämmplatten 3 bestehen aus schalldämmendem Material. Durch die Auswahl geeigneter Dämmaterialien ist es möglich, die gewünschte Schallisolationseigenschaft zu bewirken. Gleichzeitig kann sich dadurch auch eine Erhöhung der Wärmeisolation ergeben.The insulation panels 3 consist of soundproofing material. By selecting suitable insulation materials, it is possible to achieve the desired sound insulation properties. At the same time, this can also result in an increase in thermal insulation.

Eine hervorragende Eigenschaftsverbesserung läßt sich durch Dämmplatten 3 erzielen, die aus Holzweichfasern aufgebaut sind. Auch andere Arten von Faserdämmstoffen sind hierfür gut geeignet.An excellent improvement in properties can be achieved by insulating boards 3, which are made of soft wood fibers. Other types of fiber insulation materials are also well suited for this.

Als Material für die Seitenplatten 1 eignen sich geschäumte Hartkunststoffe, wie beispielsweise geschäumtes Polystyrol. Es weist einen hohen Wärmeisolationsgrad und eine gute mechanische Festigkeit auf.Foamed hard plastics, such as foamed polystyrene, are suitable as the material for the side plates 1. It has a high degree of thermal insulation and good mechanical strength.

Weitere Vorteile dieser Materialien liegen in ihrem geringen Gewicht sowie in ihrer einfachen Bearbeitbarkeit. Die hieraus hergestellten Schalungselemente können auf der Baustelle z.B. mit einer einfachen Handsäge in die gewünschte Form gebracht werden. Dies ist insbesondere dann erforderlich, wenn Eckverbindungen, Vorsprünge, Fensterstürze etc. in die Wand integriert werden müssen.Other advantages of these materials are their low weight and their easy workability. The formwork elements made from it can on the Construction site can be brought into the desired shape with a simple hand saw, for example. This is particularly necessary if corner connections, projections, lintels etc. have to be integrated into the wall.

Vorteilhafterweise werden die Verbindungselemente 2 in Form von Stegen ausgeführt. Zwar ist es auch möglich, die Verbindungselemente 2 z.B. als mehr oder weniger durchgehende Wände auszugestalten. Es ist allerdings wünschenswert, den Zwischenraum zwischen den beiden Seitenplatten 1 mit möglichst wenig großflächigen Elementen zu unterbrechen, um einerseits ein problemloses Befüllen der Hohlräume mit Beton zu ermöglichen und andererseits in der fertigen Mantelbetonwand einen weitgehend homogenen Betonkern zu erhalten. Unter diesem Aspekt ist es deshalb günstiger, eine Vielzahl relativ dünner Stege als einige wenige durchgehende Trennwände zu realisieren.The connecting elements 2 are advantageously designed in the form of webs. It is also possible to connect the connecting elements 2 e.g. as more or less continuous walls. However, it is desirable to interrupt the space between the two side plates 1 with as little large-area elements as possible, on the one hand to allow the cavities to be filled with concrete without problems and on the other hand to obtain a largely homogeneous concrete core in the finished concrete wall. From this point of view, it is therefore cheaper to implement a large number of relatively thin webs than a few continuous partitions.

Zur Erhöhung der Stabilität der Stege und damit der Eigenstabilität des Schalungselementes ist es zweckmäßig, die Stege mit einem profilierten Querschnitt auszuführen. Dies können beispieslweise Querschnitte mit T- oder Doppel-T-Profil sein, die eine hohe Sicherheit gegen Verformungen im Belastungsfall aufweisen.To increase the stability of the webs and thus the inherent stability of the formwork element, it is expedient to design the webs with a profiled cross section. For example, these can be cross-sections with a T or double T profile, which have a high degree of security against deformation in the event of load.

Die Verbindungselemente 2 bestehen bevorzugt aus Metall. Neben einer sehr hohen Festigkeit ergibt sich der zusätzliche Vorteil, daß sich damit eine feuersichere Gestaltung der Mantelbetonwand erzielen läßt. Dieser Aspekt ist insbesondere bei Mehrfamilienhäusern und Wohnanlagen gefordert, wo verhindert werden muß, daß Feuer die Wand durchschlagen kann. Diese Gefahr besteht bei Mantelbetonwänden, die Kunststoffstege aufweisen, weil sich dadurch Feuerbrücken von einer Seitenwand zur anderen Seitenwand ergeben. Bei der Vewendung von Verbindungselementen 2 aus Metall ist diese Gefahr nicht mehr gegeben.The connecting elements 2 are preferably made of metal. In addition to a very high strength, there is the additional advantage that a fire-proof design of the shell concrete wall can be achieved. This aspect is particularly required in apartment buildings and residential complexes, where it must be prevented that fire can penetrate the wall. This danger exists in the case of clad concrete walls which have plastic webs, because this creates fire bridges from one side wall to the other side wall. At the use of connecting elements 2 made of metal, this danger is no longer present.

Zur Herstellung der erfindungsgemäßen Schalungselemente werden zunächst die Dämmplatten 3 mit Schlitzen versehen, in die die Verbindungselemente 2 eingesetzt werden. Sie ragen dabei seitlich über die Dämmplatten 3 hinaus, so daß sie beim anschließenden Aufschäumen des Hartkunststoffes für die Seitenplatten 1 umschäumt und in den Seitenplatten 1 verankert werden.To manufacture the formwork elements according to the invention, the insulation panels 3 are first provided with slots into which the connecting elements 2 are inserted. They protrude laterally beyond the insulation panels 3, so that when the rigid plastic is subsequently foamed, they foam around the side panels 1 and are anchored in the side panels 1.

Ein mit Hilfe der erfindungsgemäßen Schalungselemente hergestelltes Mantelbeton-Wandelement wurde auf seine Schalldämmung hin untersucht. Der Aufbau des Wandelementes entsprach dem aus Figur 3, wobei folgende Abmessungen gewählt wurden :

  • 20,0 mm Außenputz, Kalk-Zement
  • 50,5 mm Styropor ® F214
  • 12,0 mm Holzweichfaserplatte
  • 175,0 mm Beton B 25 mit innenliegenden Metallstegen
  • 12,0 mm Holzweichfaserplatte
  • 50,5 mm Styropor ® F214
  • 15,0 mm Innenputz, Gips
Zur Bestimmung der Luftschalldämmung nach DIN 52210 wurde ein Wandelement in der Abmessung 1,820 m x 1,05 m in die Maueröffnung einer Kalksandstein-Doppelwand eingesetzt und verkeilt sowie abgedichtet. Die Beaufschlagung mit Prüfschall erfolgte mit einem sogenannten Rosarauschen, empfangsseitig erfolgte die Messung mit einem Terzbandfilter.A jacket concrete wall element produced with the help of the formwork elements according to the invention was examined for its sound insulation. The structure of the wall element corresponded to that of FIG. 3, the following dimensions being chosen:
  • 20.0 mm exterior plaster, lime cement
  • 50.5 mm Styropor ® F214
  • 12.0 mm soft wood fiber board
  • 175.0 mm concrete B 25 with internal metal bars
  • 12.0 mm soft wood fiber board
  • 50.5 mm Styropor ® F214
  • 15.0 mm interior plaster, plaster
To determine the airborne sound insulation in accordance with DIN 52210, a wall element measuring 1.820 mx 1.05 m was inserted into the wall opening of a sand-lime brick double wall and wedged and sealed. The test sound was applied with a so-called pink noise, on the receiving side the measurement was carried out with a third-octave filter.

Bewertet ergab sich ein Schalldämmaß von 51 dB. Die Grenzdämmung der Prüfanordnung bezogen auf 2 m2, gemessen nach DIN, lag bei 61 dB.A sound insulation index of 51 dB was assessed. The limit insulation of the test arrangement based on 2 m 2 , measured according to DIN, was 61 dB.
