Definitions
- the invention relates to a method for producing a multilayer, reinforced concrete element, wherein the multilayer, reinforced concrete element comprises at least a first concrete wall in combination with a reinforcing body, wherein the concrete element comprises an at least indirectly applied to the first concrete wall insulating layer and wherein the reinforcing body at least partially the first concrete wall protruding and the insulating layer is formed penetrating.
- Precast concrete plays an important role in the construction industry.
- precast concrete elements have been fitted with integrated insulation layers at the factory for a number of years, in particular for reinforced concrete walls and ceilings with core insulation.
- insulating board products in particular mineral wool and polystyrene, are introduced by hand.
- the EP 1 010 828 B1 shows a further production of a wall panel with an inner shell and an outer shell made of concrete, which are connected to one another via carriers of a reinforcing body.
- PU foam is applied to the inner side of the foam, which faces upward to apply the PU foam.
- the complementary concrete shell is then produced by immersion in a concrete bed and subsequent curing. A defined cavity for the PU foam body is not created, and a subsequent pouring with more concrete takes place on an undefined PU insulating layer surface.
- the not yet cured PU foam body, which is applied as a reaction mixture, is distributed by means of an air stream.
- the height of the cured foam results from the applied height of the reaction mixture, the height of which is again determined by the speed of the application for a given reaction time and has an irregular topography.
- a structural geometric limitation of the cavity is therefore not created, so that disadvantageously no insulating layer of a defined thickness can be formed.
- a similar method discloses the EP 1 106 745 A2 ,
- a method for producing a prefabricated ceiling element is described as a prefabricated component, wherein two sheets of reinforced concrete by a plurality of lattice girder are spaced from each other, and wherein the lattice girders are embedded in the respective disc and wherein the end sections comprise at least the longitudinal bars with welded strut knot, and wherein the space between the panes is completely filled with foamed polyurethane.
- the resulting between the two discs cavity is filled with polyurethane foam during production already.
- the hardened polyurethane layer should support the structural-technical function of the lattice girders and the concrete slabs.
- the object of the present invention is to provide an improved method for producing a multilayer, reinforced concrete element, and in particular the object of the invention is to be able to form the insulating layer of a PU foam, preferably with different thicknesses in a flexible manner.
- the essence of the invention consists in particular in that the concrete wall provided with the reinforcing body, for example with integrated metallic lattice girders or fiberglass anchors for forming the reinforcement body, upside down, ie. with the reinforcing body facing downwards, placed over a preferably vibratable bedding container or the like, in which the bed of flowable solids is provided, in particular of granules of fine granularity such as quartz sand.
- the filling height of the bed or the height at which the concrete wall is held above the surface of the bed can be set arbitrarily.
- the insulating layer can be formed highly flexible with different thicknesses.
- the thickness of the insulating layer may for example be a value of 2cm to 40cm, preferably for example from 5cm to 30cm and more preferably for example from 10cm to 25cm, as these thicknesses can be foamed particularly well with a reaction mixture.
- Reaction mixtures of polyol and isocyanate are particularly suitable for the production of polyurethane insulating layers, but the insulating layer may comprise any further insulating material, for example also a phenolic resin foam.
- the reinforcement body need not be made in one piece and it may, for example, individual, preferably glass fiber reinforced polymer rods or baskets form the reinforcing body. Also, so-called shear mandrels are known, so that the reinforcing body in particular can also be constructed from a Schubdornsystem consisting of steel elements or fiber-reinforced polymer elements which form the shear mandrels.
- Filling the clearance with the reaction mixture may be accomplished by a flexible casting system, such as a sprue system, a rigid or oscillating casting head, or a casting mandrel arranged to be located between the concrete element and the bed surface despite the presence of the reinforcing body can be moved.
- a flexible casting system such as a sprue system, a rigid or oscillating casting head, or a casting mandrel arranged to be located between the concrete element and the bed surface despite the presence of the reinforcing body can be moved.
- the casting can also be done from the side, and the reaction mixture can enter the free space.
- the term casting also encompasses any type of spraying or spraying of the reaction mixture.
- the bed can in principle be formed by any type of flowable solids and may also comprise mixtures of different solids.
- the bed should be suitable to form a barrier to the reaction mixture so as to form forming, wherein the reaction mixture, which in particular comprises the components polyol and isocyanate, can foam in about horizontally flat extending free space with vertically defined height.
- the thus created cavity forms a defined cavity with a substantially flat, parallel to the first concrete wall extending extension between the surface of the bed as the lower boundary and the underside of the first concrete wall as the upper boundary, and this cavity can in particular by means of a distribution system over the entire surface with flowable Reaction mixture or another at least phased flowable mixture are filled to form the insulating layer after curing.
- the second concrete wall can be cast onto the manufactured element or the insulated first concrete wall can be immersed in the still fresh (non-set) second concrete wall, so that the end component is a reinforced concrete sandwich element with two concrete walls and the intermediate insulating layer, in particular a PU Foam core insulation results.
- the following process step takes place after curing of the insulating layer: Insertion of the first concrete wall with the reinforcing body in a casting mold, wherein the protruding portion and the insulating layer are arranged below the first concrete wall. It can then be done filling the mold with concrete, but preferably can take place the first concrete wall in the already reinforced and freshly concreted second wall.
- the casting of the concrete for the second wall is usually carried out so before inserting the already cured first wall.
- the result is the second concrete wall, in which the protruding portion of the reinforcing body is at least partially also cast. In this embodiment, therefore, the projecting portion protrudes downwards.
- the mold is delimited upwards by the concrete wall. Depending on the amount of liquid concrete, which is introduced into the mold, the free space is thus selectively filled.
- the second concrete wall can also be formed such that the second concrete wall rests against the insulating layer, at least indirectly, by completely filling the free space. So it is then in the finished product no gap between the second concrete wall and insulation layer available.
- the free space in the casting mold between the bottom of the casting mold and the insulating layer is only partially filled with liquid concrete, so that a gap remains between the insulating layer and the second concrete wall. Such a gap can be filled with concrete, for example, later on the site.
- the composite of insulating layer and the first concrete wall is inserted with the reinforcing body in the mold, wherein the protruding portion of the reinforcing body and the insulating layer is disposed above the first concrete wall.
- the insulating layer can form the bottom of the mold thus created.
- the composite of the first concrete wall with the reinforcing body and the insulating layer is immersed in an already filled with concrete mold with the insulating layer facing down and the concrete is then cured for this process step. In This embodiment, no gap between the second concrete wall and insulation layer is generated.
- An indirect concern also means a construction in which a further layer of material is provided between the concrete wall and the adjacent insulating layer, for example an insulating film.
- a further layer of material is provided between the concrete wall and the adjacent insulating layer, for example an insulating film.
- the two layers are no longer in contact with each other.
- the concrete walls which may basically be plate-shaped, are oriented substantially horizontally.
- FIG. 2c shows a finished reinforced concrete element 10, which was prepared by a method according to the invention.
- the reinforced concrete element 10 includes an overhead arranged first concrete wall 11 and a second concrete wall spaced therefrom 12. Between the two concrete walls 11 and 12, an insulating layer 14 is provided. The insulating layer 14 is applied to the first concrete wall 11, and between the insulating layer 14 and the second concrete wall 12, a free space 20 is formed.
- Figure 3c shows an alternative reinforced concrete element 10. This corresponds largely to the structure of the reinforced concrete element after Figure 2c , wherein the free gap 22 is omitted.
- the insulating layer 14 is now also on the second concrete wall 12. Between the insulating layer 14 and the adjoining concrete walls can be arranged, for example, plastic films or other layers of material.
- a reinforcing body 13 is shown in the form of a steel reinforcement basket, visible in the space 20.
- the reinforcing body 13 is completely enclosed by concrete or the insulating layer 14 and therefore not visible.
- FIG. 1a the reinforcing body 13 is inserted in a first mold 17.
- the first mold 17 is now partially filled with liquid concrete 22.
- the concrete then cures to the first concrete wall 11, see FIG. 1b ,
- a section 13 "of the reinforcing body 13 is now cast in the first concrete wall 11.
- Another section 13 'of the reinforcing body 13 protrudes from the first concrete wall 11.
- first concrete wall (11) and reinforcing body (13) is reversed, so that the protruding portion 13 'is arranged on the underside of the first concrete wall 11.
- the bed 15 is formed by sand, in particular by quartz sand. But it is only the reinforcing body 13 with its protruding portion 13 'immersed in the bed 15.
- the first concrete wall 11 remains completely above and arranged at a distance from the bed 15. There thus remains a vertical space 16 between the first concrete wall 11 and the bed 15 in the hopper 23, see Figure 1d ,
- the bed 15 can be shaken by means of a vibrator.
- the shaking of the bed 15 is useful so as to distribute the bed as evenly as possible and to obtain a flat surface as possible.
- the free space 16 is now completely filled with a flowable reaction mixture, in the present example PU foam made of polyol and isocyanate.
- a flowable reaction mixture in the present example PU foam made of polyol and isocyanate.
- the reaction mixture becomes solid and forms a composite of the insulating layer 14 with the first concrete wall 11 and the reinforcing body, see Figure 1e , In FIG. 1f Now, the intermediate product is shown, which comprises the first concrete wall 11, the adjacent insulating layer 14 and the reinforcing body 13.
- FIG. 1f represent a finished reinforced concrete element.
- the intermediate product is inserted into a second mold 18, see FIG. 3a ,
- the reinforcing body 13 is inserted with its protruding portion 13 'down into the second mold 18.
- Spacers not shown, can ensure that the reinforcing body 13 basically has a certain distance from the bottom 19 of the casting mold 18.
- FIG. 2b It can be seen that now a free space 21 between the insulating layer 14 and the bottom 19 of the mold 18 is formed.
- the protruding portion 13 'of the reinforcing body 13 is arranged.
- This space 21 is now at least partially filled with concrete 22. There remains a gap 20, since the space 21 is only partially filled. But it is also possible that the space 21 is completely filled. So then the second concrete wall 12 is brought into contact with the insulating layer 14.
- the intermediate product becomes FIG. 1f inserted into the second mold 18, that the protruding portion 13 'of the reinforcing body 13 facing upward and so that the first concrete wall 11 is disposed below the insulating layer 14, see FIG. 3a
- FIG. 3b is now the intermediate after FIG. 1f shown within the second mold 18.
- the first concrete wall 11 rests on the bottom 19 of the second casting mold 18.
- the mold 18 is filled from above with concrete 22. Due to gravity now puts the filled concrete 22 to the insulating layer 14, so that it is not provided in this embodiment, that a gap 20 between the insulating layer and the second concrete wall 12 is formed.
- the invention is not limited in its execution to the above-mentioned preferred embodiment. Rather, a number of variants is conceivable, which of the solution shown makes use even in fundamentally different versions.

Betonfertigteile spielen in der Bauindustrie eine wichtige Rolle. Angesichts steigender Anforderungen an Energieeffizienz werden seit einigen Jahren Betonfertigteile werkseitig mit integrierten Dämmschichten ausgestattet, insbesondere betrifft dies Wand und Decken aus Stahlbeton mit einer Kerndämmung. Meist wird allerdings bei dem nahezu vollständig automatisierten Produktionsprozess händisch Dämmplattenware, insbesondere aus Mineralwolle und Polystyrol, eingebracht.Precast concrete plays an important role in the construction industry. In view of increasing demands on energy efficiency, precast concrete elements have been fitted with integrated insulation layers at the factory for a number of years, in particular for reinforced concrete walls and ceilings with core insulation. Mostly, however, in the almost completely automated production process, insulating board products, in particular mineral wool and polystyrene, are introduced by hand.

Die der Erfindung zugrundeliegende Aufgabe wird gelöst durch ein Verfahren nach Anspruch 1, vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The problem underlying the invention is achieved by a method according to claim 1, advantageous embodiments emerge from the dependent claims.
Erfindungsgemäß ist ein Verfahren zur Herstellung eines mehrschichtigen, bewehrten Betonelements vorgesehen, wobei das Betonelement eine erste Betonwandung im Verbund mit einem Bewehrungskörper umfasst und eine an der ersten Betonwandung zumindest mittelbar anliegende Dämmschicht aufweist, wobei die erste Betonwandung über einen Bewehrungskörper, insbesondere einen GFK- oder Stahlbewehrungskörper, mit der Dämmschicht und insbesondere mit einer zweiten Betonwandung verbunden ist. Das erfindungsgemäße Verfahren umfasst dabei die nachfolgend genannten Schritte:
- Als erster Schritt kann das Bereitstellen der ersten Betonwandung mit einem Bewehrungskörper erfolgen, wobei der Bewehrungskörper teilweise in die erste Betonwandung eingegossen ist. Dies kann durch Gießen und Aushärten der ersten Betonwandung in einer Gießform erfolgen, wobei während des Gießens ein Abschnitt des Bewehrungskörpers in die Betonwandung eingegossen wird (im Folgenden: eingegossener Abschnitt), und ein weiterer Abschnitt des Bewehrungskörpers kann aus der ersten Betonwandung hervorstehen (im Folgenden: hervorstehender Abschnitt). Es folgt anschließend der Schritt des Anordnens der ersten Betonwandung und dem daran angeordneten Bewehrungskörper mit einem vertikalen Abstand der Unterseite der ersten Betonwandung über einer Schüttung, insbesondere aus Quarzsand, der zuvor in ein Schüttungsbehältnis eingegeben und beispielsweise gerüttelt oder glattgestrichen wurde. Der hervorstehende Abschnitt ist dabei unterseitig der ersten Betonwandung angeordnet ist und taucht in die Schüttung ein, wobei die Schüttung insbesondere anschließend gerüttelt werden kann. Ein vordefinierter Freiraum verbleibt dabei zwischen der Oberfläche der Schüttung und der Unterseite der ersten Betonwandung.

Anschließend folgt der Schritt des Aushärtens der Dämmschicht. In einem abschließenden Schritt kann die Betonwandung mit dem Bewehrungskörper und der an diesem Verbund ausgehärteten Dämmschicht aus Polyurethan aus der Schüttung entnommen werden und insbesondere vom Material der Schüttung befreit werden.
- As a first step, the provision of the first concrete wall can be carried out with a reinforcing body, wherein the reinforcing body is partially cast in the first concrete wall. This can be carried out by casting and curing the first concrete wall in a casting mold, during casting a portion of the reinforcing body is poured into the concrete wall (hereinafter: cast-in portion), and another portion of the reinforcing body can protrude from the first concrete wall (hereinafter: prominent section). Subsequently, the step of arranging the first concrete wall and the reinforcing body arranged thereon follows with a vertical distance of the underside of the first concrete wall above a bed, in particular of quartz sand, which has been previously introduced into a bed and, for example, shaken or smoothed. The projecting portion is arranged on the underside of the first concrete wall and immersed in the bed, the bed can be shaken in particular subsequently. A predefined free space remains between the surface of the bed and the underside of the first concrete wall. This is followed by the filling of the free space with a reaction mixture to form polyurethane foam, which forms an insulating layer. This is followed by the step of curing the insulation layer. In a final step, the concrete wall can be removed from the bed with the reinforcing body and cured on this composite insulating layer of polyurethane and in particular be freed from the material of the bed.
Der Kern der Erfindung besteht insbesondere darin, dass die mit dem Bewehrungskörper versehene Betonwandung, beispielsweise mit integrierten metallischen Gitterträgern oder GFK-Ankern zur Bildung des Bewehrungskörpers, kopfüber, d.h. mit dem Bewehrungskörper nach unten weisend, über einem vorzugsweise rüttelfähigen Schüttungsbehältnis oder dergleichen platziert wird, in der die Schüttung aus fließfähigen Feststoffen vorgesehen ist, insbesondere aus einem Granulat feiner Körnung wie beispielsweise Quarzsand. Die Füllhöhe der Schüttung bzw. die Höhe, mit der die Betonwandung über der Oberfläche der Schüttung gehalten wird, kann beliebig vorgegeben werden. So kann die Dämmschicht höchst flexibel mit verschiedenen Dicken gebildet werden. Die Dicke der Dämmschicht kann beispielsweise einen Wert von 2cm bis 40cm, bevorzugt beispielsweise von 5cm bis 30cm und besonders bevorzugt beispielsweise von 10cm bis 25cm betragen, da diese Dicken besonders gut mit einem Reaktionsgemisch geschäumt werden können. Besonders eignen sich Reaktionsgemische aus Polyol und Isocyanat zur Herstellung von Polyurethan- Dämmschichten, die Dämmschicht kann jedoch jedes weitere Dämmmaterial umfassen, beispielsweise auch einen Phenolharzschaum.The essence of the invention consists in particular in that the concrete wall provided with the reinforcing body, for example with integrated metallic lattice girders or fiberglass anchors for forming the reinforcement body, upside down, ie. with the reinforcing body facing downwards, placed over a preferably vibratable bedding container or the like, in which the bed of flowable solids is provided, in particular of granules of fine granularity such as quartz sand. The filling height of the bed or the height at which the concrete wall is held above the surface of the bed can be set arbitrarily. Thus, the insulating layer can be formed highly flexible with different thicknesses. The thickness of the insulating layer may for example be a value of 2cm to 40cm, preferably for example from 5cm to 30cm and more preferably for example from 10cm to 25cm, as these thicknesses can be foamed particularly well with a reaction mixture. Reaction mixtures of polyol and isocyanate are particularly suitable for the production of polyurethane insulating layers, but the insulating layer may comprise any further insulating material, for example also a phenolic resin foam.
Der Bewehrungskörper muss nicht einstückig ausgeführt sein und es können beispielsweise auch einzelne, vorzugsweise glasfaserverstärkte Polymerstäbe oder -körbe den Bewehrungskörper bilden. Auch sind sogenannte Schubdorne bekannt, sodass der Bewehrungskörper insbesondere auch aus einem Schubdornsystem aufgebaut sein kann, das aus Stahlelementen oder faserverstärkten Polymerelementen besteht, die die Schubdorne bilden.The reinforcement body need not be made in one piece and it may, for example, individual, preferably glass fiber reinforced polymer rods or baskets form the reinforcing body. Also, so-called shear mandrels are known, so that the reinforcing body in particular can also be constructed from a Schubdornsystem consisting of steel elements or fiber-reinforced polymer elements which form the shear mandrels.
Das Ausfüllen des Freiraumes mit dem Reaktionsgemisch kann durch ein flexibles Gießsystem erfolgen, beispielsweise mit einem Gießharkensystem, mit einem starren oder mit einem oszillierenden Gießkopf oder mit einem Gießdorn, der so beschaffen ist, dass dieser trotz des Vorhandenseins des Bewehrungskörpers zwischen das Betonelement und die Schüttungsoberfläche bewegt werden kann. Bevorzugt kann jedoch das Gießen auch von der Seite erfolgen, und das Reaktionsgemisch kann in den Freiraum einlaufen. Der Begriff des Gießens umfasst dabei ebenfalls jede Art des Sprühens oder Spritzens des Reaktionsgemisches.Filling the clearance with the reaction mixture may be accomplished by a flexible casting system, such as a sprue system, a rigid or oscillating casting head, or a casting mandrel arranged to be located between the concrete element and the bed surface despite the presence of the reinforcing body can be moved. Preferably, however, the casting can also be done from the side, and the reaction mixture can enter the free space. The term casting also encompasses any type of spraying or spraying of the reaction mixture.
Die Schüttung kann grundsätzlich durch jede Art von fließfähigen Feststoffen gebildet werden und kann auch Mischungen unterschiedlicher Feststoffe umfassen. Die Schüttung soll dabei geeignet sein, eine Barriere für das Reaktionsgemisch zu bilden um so formbildend zu wirken, wobei das Reaktionsgemisch, das insbesondere die Komponenten Polyol und Isocyanat umfasst, im sich etwa horizontal flach erstreckenden Freiraum mit vertikal definierter Höhe aufschäumen kann.The bed can in principle be formed by any type of flowable solids and may also comprise mixtures of different solids. The bed should be suitable to form a barrier to the reaction mixture so as to form forming, wherein the reaction mixture, which in particular comprises the components polyol and isocyanate, can foam in about horizontally flat extending free space with vertically defined height.
Hierfür hat sich insbesondere Quarzsand als geeignet herausgestellt. Der so geschaffene Hohlraum bildet eine definierte Kavität mit einer im Wesentlichen flachen, parallel zur ersten Betonwandung sich erstreckenden Ausdehnung zwischen der Oberfläche der Schüttung als untere Begrenzung und der Unterseite der ersten Betonwandung als obere Begrenzung, und dieser Hohlraum kann insbesondere mittels eines Verteilungssystems vollflächig mit fließfähigem Reaktionsgemisch oder einem anderen zumindest phasenweise fließfähigen Gemisch befüllt werden, um nach einer Aushärtung die Dämmschicht zu bilden.For this particular quartz sand has been found to be suitable. The thus created cavity forms a defined cavity with a substantially flat, parallel to the first concrete wall extending extension between the surface of the bed as the lower boundary and the underside of the first concrete wall as the upper boundary, and this cavity can in particular by means of a distribution system over the entire surface with flowable Reaction mixture or another at least phased flowable mixture are filled to form the insulating layer after curing.
Im Anschluss daran kann die zweite Betonwandung an das hergestellte Element angegossen oder die gedämmte erste Betonwandung in die noch frische (nicht-abgebundene) zweite Betonwandung eingetaucht werden, so dass sich als Endbauteil ein Stahlbetonsandwichelement mit zwei Betonwandungen und der dazwischen liegenden Dämmschicht, insbesondere einer PU-Hartschaumkerndämmung, ergibt.Following this, the second concrete wall can be cast onto the manufactured element or the insulated first concrete wall can be immersed in the still fresh (non-set) second concrete wall, so that the end component is a reinforced concrete sandwich element with two concrete walls and the intermediate insulating layer, in particular a PU Foam core insulation results.
Es hat sich gezeigt, dass der Einsatz einer Polyurethanhartschaumdämmung, die als flüssige, reaktive Mischung in den Freiraum eingebracht werden kann, deutliche Vorteile hinsichtlich einer effizienteren, automatisierten Herstellung und/oder eines energieeffizienteren, schlankeren Bauteils ermöglicht. Es kann durch das erfindungsgemäße Verfahren ein automatisierter Eintrag einer Polyurethandämmschicht als flüssige Reaktionsmischung ermöglicht werden und in den gesamten Produktionsprozess integriert werden.It has been found that the use of a rigid polyurethane foam, which can be introduced as a liquid, reactive mixture in the free space, allows significant advantages in terms of a more efficient, automated production and / or a more energy efficient, slimmer component. It can by the inventive method an automated entry a polyurethane barrier layer as a liquid reaction mixture are made possible and integrated into the entire production process.
In einer ersten bevorzugten Ausgestaltung erfolgt nach dem Aushärten der Dämmschicht der folgende Verfahrensschritt: Einlegen der ersten Betonwandung mit dem Bewehrungskörper in eine Gießform, wobei der hervorstehende Abschnitt und die Dämmschicht unterhalb der ersten Betonwandung angeordnet sind. Es kann anschließend das Auffüllen der Gießform mit Beton erfolgen, bevorzugt kann jedoch das Einlegen der ersten Betonwandung in die bereits bewehrte und frisch betonierte zweite Wandung stattfinden.In a first preferred embodiment, the following process step takes place after curing of the insulating layer: Insertion of the first concrete wall with the reinforcing body in a casting mold, wherein the protruding portion and the insulating layer are arranged below the first concrete wall. It can then be done filling the mold with concrete, but preferably can take place the first concrete wall in the already reinforced and freshly concreted second wall.
Das Gießen des Betons für die zweite Wandung erfolgt üblicherweise also vor dem Einlegen der bereits ausgehärteten ersten Wandung. So entsteht die zweite Betonwandung, in die der hervorstehende Abschnitt des Bewehrungskörpers zumindest teilweise ebenfalls eingegossen wird. In dieser Ausgestaltung ragt also der hervorstehende Abschnitt nach unten. Die Gießform wird nach oben durch die Betonwandung abgegrenzt. Je nach Menge an flüssigem Beton, die in die Gießform eingebracht ist, wird der Freiraum somit gezielt aufgefüllt.The casting of the concrete for the second wall is usually carried out so before inserting the already cured first wall. The result is the second concrete wall, in which the protruding portion of the reinforcing body is at least partially also cast. In this embodiment, therefore, the projecting portion protrudes downwards. The mold is delimited upwards by the concrete wall. Depending on the amount of liquid concrete, which is introduced into the mold, the free space is thus selectively filled.
Dabei kann auch wahlweise durch ein vollständiges Auffüllen des Freiraums die zweite Betonwandung derart gebildet werden, dass die zweite Betonwandung an die Dämmschicht zumindest mittelbar anliegt. Es ist also dann im fertigen Produkt kein Zwischenraum mehr zwischen zweiter Betonwandung und Dämmschicht vorhanden. Alternativ kann aber auch vorgesehen sein, dass der Freiraum in der Gießform zwischen dem Boden der Gießform und der Dämmschicht nur teilweise mit flüssigem Beton ausgegossen wird, so dass ein Zwischenraum zwischen der Dämmschicht und der zweiten Betonwandung verbleibt. Ein solcher Zwischenraum kann beispielsweise später auf der Baustelle mit Beton aufgefüllt werden.Optionally, the second concrete wall can also be formed such that the second concrete wall rests against the insulating layer, at least indirectly, by completely filling the free space. So it is then in the finished product no gap between the second concrete wall and insulation layer available. Alternatively, however, it can also be provided that the free space in the casting mold between the bottom of the casting mold and the insulating layer is only partially filled with liquid concrete, so that a gap remains between the insulating layer and the second concrete wall. Such a gap can be filled with concrete, for example, later on the site.
In einer zweiten bevorzugten Ausgestaltung ist vorgesehen, dass nach dem Aushärten der Verbund aus Dämmschicht und der ersten Betonwandung mit dem Bewehrungskörper in die Gießform eingelegt wird, wobei der hervorstehende Abschnitt des Bewehrungskörpers und die Dämmschicht oberhalb der ersten Betonwandung angeordnet ist. In diesem Fall kann die Dämmschicht den Boden der so geschaffenen Gießform bilden. Das anschließende Auffüllen dieser Gießform mit flüssigem Beton wird dann dazu führen, dass zwangsläufig die zweite Betonwandung zumindest mittelbar in Anlage mit der Dämmschicht gebracht wird. Bevorzugt wird auch für diesen Verfahrensschritt der Verbund aus der ersten Betonwandung mit dem Bewehrungskörper und der Dämmschicht in eine bereits mit Beton verfüllte Gießform mit der Dämmschicht nach unten weisend eingetaucht und der Beton wird anschließend ausgehärtet. In dieser Ausgestaltung wird kein Zwischenraum zwischen zweiter Betonwandung und Dämmschicht erzeugt.In a second preferred embodiment, it is provided that after curing, the composite of insulating layer and the first concrete wall is inserted with the reinforcing body in the mold, wherein the protruding portion of the reinforcing body and the insulating layer is disposed above the first concrete wall. In this case, the insulating layer can form the bottom of the mold thus created. The subsequent filling of this mold with liquid concrete will then cause inevitably the second concrete wall is at least indirectly brought into contact with the insulating layer. Preferably, the composite of the first concrete wall with the reinforcing body and the insulating layer is immersed in an already filled with concrete mold with the insulating layer facing down and the concrete is then cured for this process step. In This embodiment, no gap between the second concrete wall and insulation layer is generated.
Unter einem mittelbaren Anliegen ist dabei auch ein Aufbau gemeint, bei dem zwischen der Betonwandung und der daran anliegenden Dämmschicht eine weitere Materiallage vorgesehen ist, beispielsweise eine Isolierfolie. Sollte allerdings zwischen zwei Schichten ein freier, insbesondere mit Luft befüllter Zwischenraum vorgesehen sein, so befinden sich die beiden Schichten nicht mehr in Anlage miteinander.An indirect concern also means a construction in which a further layer of material is provided between the concrete wall and the adjacent insulating layer, for example an insulating film. However, should a free, in particular filled with air gap between two layers are provided, the two layers are no longer in contact with each other.
Während der Auffüllvorgänge sind die Betonwandungen, die grundsätzlich plattenförmig sein können, im Wesentlichen horizontal ausgerichtet.During the filling operations, the concrete walls, which may basically be plate-shaped, are oriented substantially horizontally.
