Description

Die Erfindung betrifft eine Verbindung nach dem Oberbegriff des Anspruches 1 und ein Verfahren zu ihrer Herstellung nach dem Oberbegriff des Anspruches 5.The invention relates to a connection according to the preamble of claim 1 and a method for its production according to the preamble of claim 5.

In Sandwichbauweise aufgebaute Wandelemente der gattungsgemässen Art werden unter anderem zum Bau von Kühl- und Tiefkühlhäusern, Schlachthäusern, Obst- und Gemüsekühlhäusern und sogenannten CA-Lagern, d. h. Lagerhäusern mit gesteuerter Atmosphäre, eingesetzt. Ausser guten Wärmedämmeigenschaften müssen solche Häuser feuerbeständig sein. Während die Feuerbeständigkeit der Wandelemente im Bereich ihrer Hauptflächen recht gut ist, da die tragende Innenplatte und die Fassadenplatte jeweils aus Stahl-Beton bestehen, ist es schwierig, eine feuerbeständige Verbindung zwischen benachbarten Wandelementen herzustellen. Man hat sich bisher -soweit es um die Stossfuge zwischen den Fassadenplatten geht - damit beholfen, nach der Verbindung der Wandelemente diese Stossfuge mit feuerbeständigem material, wie Asbest, oder einem von aussen vorgesetzten Betonriegel zu verschliessen. Diese Massnahmen vermögen nicht zu befriedigen.Wall elements of the generic type constructed in sandwich construction are used, among other things, for the construction of cold stores and deep-freeze stores, slaughterhouses, fruit and vegetable cold stores and so-called CA warehouses, i.e. H. Controlled atmosphere warehouses. In addition to good thermal insulation properties, such houses must be fire-resistant. While the fire resistance of the wall elements in the area of their main surfaces is quite good, since the load-bearing inner plate and the facade plate are each made of steel-concrete, it is difficult to make a fire-resistant connection between adjacent wall elements. So far - as far as the butt joint between the facade panels is concerned - one has managed to close this butt joint with fire-resistant material such as asbestos or a concrete bar placed from the outside after connecting the wall elements. These measures are unsatisfactory.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Verbindung der gattungsgemässen Art zu schaffen, die einfach herzustellen ist und absolut feuerbeständig ist. Ausserdem soll ein Verfahren zur Herstellung der Verbindung angegeben werden.The invention is therefore based on the object of providing a connection of the generic type which is simple to manufacture and is absolutely fire-resistant. In addition, a method for producing the compound is to be specified.

Die der Erfindung zugrundeliegende Aufgabe wird bei der gattungsgemässen Verbindung durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Die Feuerdämmplatte liegt im Inneren der Wandelemente und schliesst die einen Platten unter Überbrückung der Stossfuge im Bereich ihrer Innenseiten nach aussen vollständig feuersicher ab. Der Freiraum zwichen den Wärmedämmschichten benachbarter Wandelemente steht vollkommen zum Ausfüllen mit Wärmedämmaterial zur Verfügung, so dass auch die Wärmedämmeigenschaften im Bereich der Stossstelle nicht beeinträchtigt werden. Schliesslich ist eine saubere und glatte Unterlage für die Verbindung der üblicherweise vorhandenen folienförmigen Dampfsperren vorhanden.The object underlying the invention is achieved in the generic connection by the characterizing features of claim 1. The fire insulation board is located inside the wall elements and closes one of the boards completely by fire protection by bridging the butt joint in the area of their inner sides. The space between the thermal insulation layers of adjacent wall elements is completely available for filling with thermal insulation material, so that the thermal insulation properties in the area of the joint are not impaired. Finally, there is a clean and smooth underlay for the connection of the usual foil-shaped vapor barriers.

Beim Einsatz der erfindungsgemässen Massnahmen bei Aussen-Wandelementen werden die erfindungsgemässen Massnahmen bevorzugt an der Innenseite der Fassadenplatten angewendet; sie können gleichermassen aber auch an der entsprechenden Innenseite der tragenden Innenplatte eingesetzt werden. Wenn die Wandelemente als Innen-Wandelemente ausgebildet sind, bei denen jeweils beide Platten tragen, dann bestimmt sich die Lage der feuerfesten Verbindung nach nicht mit der Erfindung unmittelbar zusammenhängenden bautechnischen Gesichtspunkten.When the measures according to the invention are used for external wall elements, the measures according to the invention are preferably applied to the inside of the facade panels; but they can also be used on the corresponding inside of the supporting inner plate. If the wall elements are designed as interior wall elements, in each of which both plates are supported, the position of the refractory connection is determined according to structural aspects not directly related to the invention.

Wenn die Massnahmen nach Anspruch 2 vorgesehen sind, wird die Verbindung der Dampfsperren noch weiter erleichtert.If the measures are provided according to claim 2, the connection of the vapor barriers is made even easier.

Die Massnahmen nach Anspruch 3 dienen einer Verbesserung der Montierbarkeit der Feuerdämmplatte und der Rauchgasabdichtung.The measures according to claim 3 serve to improve the mountability of the fire insulation board and the flue gas seal.

Durch die Massnahmen nach Anspruch 4 können die Wandelemente auch noch an der Aussenseite der anderen, nicht bereits feuerfest verbundenen Platten mit einer gleichartig aufgebauten feuerfesten Verbindung gekoppelt werden.As a result of the measures according to claim 4, the wall elements can also be coupled on the outside of the other, not already fire-resistant, panels with a similarly constructed fire-resistant connection.

Durch das Verfahren nach Anspruch 5 wird die Verbindung von innen her aufgebaut, d. h. es wird zuerst die feuerdämmplatte eingebaut. Diese Arbeit kann also qualitativ besonders hochwertig ausgeführt werden im Gegensatz zum nachträglichen Einstopfen von Asbest od. dgl. in die Stossfuge.By the method of claim 5, the connection is established from the inside, i. H. the fire insulation board is installed first. This work can therefore be carried out in a particularly high quality, in contrast to the subsequent plugging of asbestos or the like into the butt joint.

Die Verfahrensmassnahmen nach Anspruch 6 geben an, wie noch die zusätzliche feuerfeste Verbindung hergestellt wird.The procedural measures according to claim 6 indicate how the additional refractory connection is still made.

Weitere Vorteile und Merkmale der Erfindung ergeben sich aus der nachfolgenden Beschreibung von Ausführungsbeispielen anhand der Zeichnung. Es zeigt:

  • Fig.1 zwei benachbarte Aussen-Wandelemente im Bereich ihrer Stossstelle im Schnitt mit einer erfindungsgemässen feuerbeständigen Verbindung zwischen Fassadenplatten,
  • Fig. 2 eine abgewandelte Ausführungsform mit einer feuerfesten Verbindung zwischen jeweils beiden Platten,
  • Fig. 3 zwei benachbarte Innen-Wandelemente im Bereich ihrer Stossstelle im Schnitt mit einer feuerfesten Verbindung entsprechend Fig. 1, und
  • Fig. 4 zwei benachbarte Innen-Wandelemente mit einer feuerfesten Verbindung beider Platten entsprechend der Darstellung in Fig. 2.
Further advantages and features of the invention result from the following description of exemplary embodiments with reference to the drawing. It shows:
  • 1 two adjacent outer wall elements in the area of their abutment on average with a fire-resistant connection according to the invention between facade panels,
  • 2 shows a modified embodiment with a refractory connection between each of the two plates,
  • 3 shows two adjacent inner wall elements in the area of their abutment on average with a refractory connection according to FIG. 1, and
  • 4 shows two adjacent inner wall elements with a fire-proof connection of the two plates as shown in FIG. 2.

Bei dem Ausführungsbeispiel nach Fig. 1 sind entsprechend der Anordnung in einer Wand zwei Wandelemente 1, 1' fluchtend auf Stoss zueinander angeordnet. Beide Wandelemente sind in Sandwich-Bauweise aufgebaut, d. h. sie weisen jeweils eine als tragende Platte 2, 2' dienende Innenplatte, eine hier zweilagige Wärmedämmschicht 3, 3', eine Dampfsperre 4, 4' und eine als Fassadenplatte dienende Platte 5, 5' auf. Die Platten 2, 2' und die Platten 5, 5' bestehen üblicherweise aus Stahl-Beton. Die Wärmedämmschicht 3, 3' besteht aus geeignetem Wärmedämmmaterial, üblicherweise einem geschäumten Kunststoff, wie geschäumtem Polystyrol. Die Dampfsperre 4,4' wird durch eine Folie aus Metall und/oder Kunststoff gebildet. Eine wärmebrükkenfreie Verbindung der Platten 2, 2' mit den Platten 5, 5' ist aus den DE-OSen 2600346 und 2820920 bekannt. Da der Beton, aus dem die Platten 2, 2' und 5, 5' hergestellt sind, feuerbeständig ist, sind die Wandelemente selber bei einer feuerbeaufschlagung ihrer Hauptflächen feuerbeständig. Probleme treten lediglich im Bereich der Stossfugen zweier benachbarter Wandelemente 1, 1'auf.In the exemplary embodiment according to FIG. 1, two wall elements 1, 1 ′ are arranged flush with one another in accordance with the arrangement in a wall. Both wall elements are constructed in sandwich construction, i. H. they each have an inner plate serving as a load-bearing plate 2, 2 ', a two-layer thermal insulation layer 3, 3' here, a vapor barrier 4, 4 'and a plate 5, 5' serving as a facade plate. The plates 2, 2 'and the plates 5, 5' are usually made of steel-concrete. The heat insulation layer 3, 3 'consists of suitable heat insulation material, usually a foamed plastic, such as foamed polystyrene. The vapor barrier 4,4 'is formed by a foil made of metal and / or plastic. A heat bridge-free connection of the plates 2, 2 'with the plates 5, 5' is known from DE-OSen 2600346 and 2820920. Since the concrete from which the panels 2, 2 'and 5, 5' are made is fire-resistant, the wall elements themselves are fire-resistant when their main surfaces are exposed to fire. Problems only occur in the area of the butt joints of two adjacent wall elements 1, 1 '.

Jede als Fassadenplatte dienende Platte 5 und 5'weist an ihrer Innenseite, also an der der Dampfsperre 4 bzw. 4' zugewandten Seite eine von ihrer Stossfläche 6 bzw. 6' zurückspringende Hinterschneidung 7 bzw. 7' auf. Im Grund dieser Hinterschneidung 7 bzw. 7' ist eine flache Leiste 8, 8' aus einem feuerbeständigen Material, beispielsweise einem kalziumsilikathaltigen Material, beispielsweise mittels Schrauben 9 (Fig. 1 links) oder durch Einlegen bei der Plattenherstellung (Fig. 1 rechts), befestigt.Each panel 5 and 5 'serving as a facade panel has an undercut 7 or 7' on its inside, ie on the side facing the vapor barrier 4 or 4 ', which recesses back from its abutting surface 6 or 6'. In the base of this undercut 7 or 7 'is a flat bar 8, 8' a fire-resistant material, for example a material containing calcium silicate, for example by means of screws 9 (FIG. 1 left) or by inserting it during plate manufacture (FIG. 1 right).

Nachdem die beiden benachbarten Wandelemente 1,1' unter Freilassung einer Stossfuge 10 zwischen den beiden Fassadenplatten fluchtend gegeneinandergesetzt worden sind, wird auf diesen beiden Leisten 8, 8' eine Feuerdämmplatte 11, beispielsweise eine Kalziumsilikatplatte, befestigt, die den durch die beiden Hinterschneidungen 7, 7' und die Stossfuge 10 gebildeten Raum vollständig ausfüllt, und zwar bündig mit der Innenseite 12, 12' der Platten 5, 5', also bündig mit den Dampfsperren 4,4'. Die Befestigung der feuerdämmplatte 11 erfolgt z. B. mittels Schrauben 13 (Fig. 1 links) oder Klammern oder Kleben (Fig. 1 rechts) auf den Leisten 8. Damit ist ein feuerbeständiger Verschluss zwischen den beiden benachbarten als Fassadenplatten dienenden Platten 5, 5' geschaffen, der gleichzeitig eine glatte Auflage für die Dampfsperren 4, 4' bietet und der gleichzeitig den vollen Querschnitt für die Warmedämmschicht verfügbar lässt. Die dichten Berührungsflächen zwischen der Feuerdämmplatte 11 einerseits und den Leisten 8, 8' andererseits sind verhältnismässig gross. Die Anbringung der Feuerdämmplatte 11 erfolgtvon der Innenseite her, also durch den Freiraum zwischen den Wärmedämmschichten 3, 3' und den Inneplatten 2, 2'.After the two adjacent wall elements 1, 1 'have been placed flush against one another, leaving a butt joint 10 between the two facade panels, a fire insulation panel 11, for example a calcium silicate panel, is attached to these two strips 8, 8', 7 'and the butt joint 10 completely fills the space formed, namely flush with the inside 12, 12' of the plates 5, 5 ', ie flush with the vapor barriers 4,4'. The attachment of the fire insulation board 11 takes place, for. B. by means of screws 13 (Fig. 1 left) or clips or gluing (Fig. 1 right) on the strips 8. This creates a fire-resistant closure between the two adjacent panels 5, 5 'serving as a smooth surface for the vapor barriers 4, 4 'and which at the same time leaves the full cross section available for the thermal insulation layer. The tight contact surfaces between the fire insulation board 11 on the one hand and the strips 8, 8 'on the other hand are relatively large. The fire insulation board 11 is attached from the inside, that is to say through the space between the heat insulation layers 3, 3 'and the inner boards 2, 2'.

Nach Anbringen der Feuerdämmplatte 11 können die ohnehin über Stossflächen 6, 6' der Platten 5, 5' hinausstehenden Dampfsperren 4, 4' überlappt und miteinander verklebt oder verschweisst werden. Alternativ kann auch in üblicher Weise eine Verbindung der beiden Dampfsperren 4, 4' auf Stoss vorgenommen werden.After attaching the fire insulation board 11, the vapor barriers 4, 4 'which project beyond the abutting surfaces 6, 6' of the boards 5, 5 'can be overlapped and glued or welded together. Alternatively, the two vapor barriers 4, 4 'can also be connected in a butt in the usual way.

Im Anschluss daran wird der abgesetzt ausgebildete Freiraum 14 zwischen den zweilagigen Wärmedämmschichten 3, 3' mit Isoliermaterial ausgefüllt. Im vorliegenden Fall werden zwei lsoliereinsätze 15,16 eingefügt, die aus dem gleichen Material bestehen wie die Wärmedämmschicht 3, 3'.Subsequently, the separated space 14 between the two-layer thermal insulation layers 3, 3 'is filled with insulating material. In the present case, two insulating inserts 15, 16 are inserted, which consist of the same material as the thermal insulation layer 3, 3 '.

Anschliessend wird die Fuge 17 zwischen den als Innenplatten dienenden Platten 2, 2' durch Ortbeton verschlossen.The joint 17 between the plates 2, 2 'serving as inner plates is then closed by in-situ concrete.

Beim Ausführungsbeispiel nach Fig. 2 werden gleichermassen wie beim Ausführungsbeispiel nach Fig. 1 Aussen-Wandelemente miteinander verbunden. Sie unterscheiden sich darin voneinander, dass die feuerbeständige Verbindung nicht an den Fassadenplatten, sondern zwischen den tragenden Innenplatten angebracht wird. Wegen der ansonsten grossen Ähnlichkeit werden für vergleichbare Teile dieselben Bezugsziffern wie beim Ausführungsbeispiel nach Fig. 1 eingesetzt, denenjeweils ein "a" nachgesetzt wird.In the exemplary embodiment according to FIG. 2, outer wall elements are connected to one another in the same way as in the exemplary embodiment according to FIG. 1. They differ from each other in that the fire-resistant connection is not attached to the facade panels, but between the load-bearing interior panels. Because of the otherwise great similarity, the same reference numerals are used for comparable parts as in the exemplary embodiment according to FIG. 1, which are followed by an " a".

In diesem Fall sind also die Hinterschneidungen 7a, 7a' in den als tragende Innenplatten dienenden Platten 5a, 5a' ausgebildet. Der Einbau der Feuerdämmplatte 11 a erfolgt durch die Fuge 17a zwischen den beiden als Fassadenplatten dienenden Platten 2a, 2a' und dem Freiraum 14a zwischen den in diesem Fall nur einlagig ausgebildeten Wärmedämmschichten 3a, 3a' an den Leisten 8a und 8a'. Der Freiraum 14a wird im vorliegenden Fall vor Ort ausgeschäumt, da ein sogenannter Stufenverschluss, wie beim Ausführungsbeispiel nach Fig. 1, nicht möglich ist. Anschliessend werden die beiden Dampfsperren 4a und 4a' miteinander verbunden. Selbstverständlich sind auch bei diesem Ausführungsbeispiel die Dampfsperren 4a bzw. 4a' der jeweiligen Platte 2a bzw. 2a' zugeordnet, die als Fassadenplatte dient.In this case, the undercuts 7a, 7a 'are thus formed in the plates 5a, 5a' serving as supporting inner plates. The fire insulation panel 11a is installed through the joint 17a between the two panels 2a, 2a 'serving as facade panels and the free space 14a between the thermal insulation layers 3a, 3a', which in this case have only one layer, on the strips 8a and 8a '. In the present case, the free space 14a is foamed on site, since a so-called step lock, as in the exemplary embodiment according to FIG. 1, is not possible. The two vapor barriers 4a and 4a 'are then connected to one another. In this exemplary embodiment, of course, the vapor barriers 4a and 4a 'are assigned to the respective panel 2a and 2a', which serves as a facade panel.

Die Fuge 17a zwischen den Platten 2a und 2a' wird mit einem "Feuerverschluss" verschlossen, der aus einer Feuerdämmplatte 18a besteht, die bündig mit den Aussenseiten 19a und 19a' der als Fassadenplatten dienenden Platten 2a, 2a' angeordnet wird. Sie wird in Hinterschneidungen 20a, 20a' der Platten 2a, 2a' angeordnet, an deren Grund ebenfalls Leisten 21 a, 21 a' als "Konterlattung" befestigt sein können. Der zwischen der Feuerdämmplatte 18a und den Dampfsperren 4a, 4a' verbleibende Raum kann hohl bleiben oder aber mit einer Mineralfaserplatte od. dgl. ausgestopft werden.The joint 17a between the panels 2a and 2a 'is closed with a " fire seal" which consists of a fire insulation panel 18a which is arranged flush with the outer sides 19a and 19a' of the panels 2a, 2a 'serving as facade panels. It is arranged in undercuts 20a, 20a 'of the plates 2a, 2a', on the bottom of which strips 21a, 21a 'can also be attached as "counter battens". The space remaining between the fire insulation board 18a and the vapor barriers 4a, 4a 'can remain hollow or can be stuffed with a mineral fiber board or the like.

Die Stossfuge 10a zwischen den tragenden Platten 5a, 5a' kann - wie bei dem Ausführungsbeispiel nach Fig. 1 - noch in geeigneter Weise verschlossen werden, beispielsweise durch einen geeigneten Kitt.The butt joint 10a between the supporting plates 5a, 5a 'can - as in the embodiment according to FIG. 1 - still be closed in a suitable manner, for example by means of a suitable cement.

Im Ausführungsbeispiel nach Fig. 3 sind die Wandelemente 1b, 1 b' als Innen-Wandelemente ausgebildet, d. h. beide Platten 2b bzw. 2b' und 5b bzw. 5b' sind als tragende Platten ausgebildet, zwischen denen eine- in diesem Fall wieder zweilagige - Wärmedämmschicht 3b, 3b' angeordnet ist. Wegen der weitgehenden Übereinstimmung, da Aufbau und Montage ansonsten identisch zum Ausführungsbeispiel nach Fig. 1 sind, kann auf die Beschreibung zum Ausführungsbeispiel nach Fig.1 verwiesen werden. Es werden ansonsten alle mit Fig. 1 übereinstimmenden Teile mit der gleichen Bezugsziffer jeweils mit einem zusätzlichen "b" versehen. Anstelle der Dampfsperre 4b, 4b' kann die jeweilige Dampfsperre auch der anderen Platte 2b bzw. 2b' zugeordnet sein; es können auch beidseitig der Wärmedämmschicht 3b, 3b' Dampfsperren vorgesehen sein.In the exemplary embodiment according to FIG. 3, the wall elements 1b, 1b 'are designed as inner wall elements, ie both plates 2b or 2b' and 5b or 5b 'are designed as load-bearing plates, between which one - in this case again two-layer - Thermal insulation layer 3b, 3b 'is arranged. Because of the large degree of correspondence, since construction and assembly are otherwise identical to the exemplary embodiment according to FIG. 1, reference may be made to the description of the exemplary embodiment according to FIG. 1. Otherwise, all parts corresponding to FIG. 1 are provided with the same reference number with an additional " b". Instead of the vapor barrier 4b, 4b ', the respective vapor barrier can also be assigned to the other plate 2b or 2b'; vapor barriers can also be provided on both sides of the thermal insulation layer 3b, 3b '.

Bei dem Ausführungsbeispiel nach Fig. 4 sind die Wandelemente 1 c, 1 c' wiederum zu einer Innenwand zusammengesetzt, d. h. beide Platten 2c, 2c' und 5c, 5c' sind als tragende Platten ausgebildet. Die Verbindung zwischen den beiden Platten entspricht wiederum der Verbindung nach Fig. 2. Insofern darf auf die Beschreibung zu Fig. 2 verwiesen werden. Zur Unterscheidung ist den jeweiligen Bezugsziffern aber ein "c" nachgesetzt.In the exemplary embodiment according to FIG. 4, the wall elements 1 c, 1 c 'are in turn assembled to form an inner wall, ie both plates 2c, 2c' and 5c, 5c 'are designed as load-bearing plates. The connection between the two plates in turn corresponds to the connection according to FIG. 2. In this respect, reference may be made to the description of FIG. 2. To differentiate, the respective reference numbers are followed by a " c".

Bei allen Ausführungsbeispielen kann der Raum zwischen den Leisten 8, 8'; 8a, 8a'; 8b, 8b'; 8c, 8c'; 21 a, 21 a'; 21 c, 21 c' und dazugehörigen Platten mit Wasserglas ausgestrichen sein. Gleichermassen kann die Feuerdämmplatte 11, 11 a, 11 b, 11 c, 18a, 18c jeweils mit Wasserglas ausgestrichen sein, um hierdurch noch eine erhöhte Rauchgasdichtigkeit der entsprechenden Stossfuge zu erzielen.In all of the exemplary embodiments, the space between the strips 8, 8 '; 8a, 8a '; 8b, 8b '; 8c, 8c '; 21 a, 21 a '; 21 c, 21 c 'and associated plates with water glass. Likewise, the fire insulation board 11, 11 a, 11 b, 11 c, 18a, 18c can each be coated with water glass in order to achieve an increased smoke gas tightness of the corresponding butt joint.
