Definitions
- the invention relates to a building element for the creation of interior walls, exterior walls and / or ceilings or roofs, preferably flat or slightly inclined roofs of a building, consisting of an insulating core forming insulation layer bound with a binder mineral fibers, in particular bound with a synthetic resin rockwool and / or glass wool fibers, and at least one preferably metallic cover layer, which is arranged on a large surface of the insulating layer, wherein between the cover layer and the insulating layer, a layer of an adhesive is arranged, which adheres the cover layer with the insulating layer.
- Such sandwich elements are also formed with an insulating core of polyurethane (PUR), which are also classified in the building material class B1, so that it is not readily apparent to users of these building elements, which advantages have building elements with an insulating core of fiber insulation.
- PUR polyurethane
- sandwich panels with a polyurethane insulating core unlike sandwich panels with a core of fiber insulation, are not suitable for classified fire protection solutions F30 - F120.
- Polyurethane-based organic adhesives have been found to be suitable for making sandwich panels having a mineral wool insulating core and sheet metal facing layers.
- the one- or two-component organic-based adhesives used ensure the required bond between the insulating core and the outer layers.
- the mineral fibers are used as insulating material for the insulating core expanded mineral materials, such as perlites. Also building material boards based on gypsum and cement are sometimes installed to protect a non-temperature-resistant insulating core between the cover layer and the insulating core.
- the above-described sandwich elements have proven themselves for use in vertical alignment. In ceiling structures or inclined structures but can be seen in such sandwich elements that dissolves in a fire test facing the fire facing cover layer after a short time from the insulating core.
- the reason for this is that the lack of temperature resistance of the organic adhesive causes that already at a temperature of 100 to 150 ° C, this adhesive is soft and burns at higher temperatures, so that the bond between the insulating core and the cover layer is dissolved and the cover layer can deform such that a fireproof connection between the individual sandwich elements, which form, for example, a ceiling surface, no longer exists. This results in an increased temperature breakdown, especially in the joint area.
- inorganic adhesives have been used which can also be exposed to temperatures of more than 1000.degree.
- adhesives improve the long-term strength of fire protection elements in horizontal or inclined structures, but due to the long curing time and the added amounts of water in the field of building elements described here are only limited use, as they allow continuous production, for example in a continuous double belt system only conditionally.
- the focus is on the fact that the finished building elements can be handled as directly as possible after the joining of their components, thus of the insulating core and the cover layers. This fast handling is counteracted by the long curing times of, for example, based on water glass based inorganic adhesive. Gypsum or cement-based adhesives are also not an alternative, since long curing times of the adhesive must also be taken into account here.
- the invention is therefore based on the object to further develop a generic building element such that a quick handling of the finished building elements at the end of a continuous production with high fire protection is possible, so that the building elements can also be used in the roof area with larger angles of inclination.
- the layer consists of a first fast-setting adhesive and a second, effective in direct fire exposure with temperatures up to about 1000 ° C adhesive, which are arranged in separate regions of the layer.
- connection between the insulating core and the cover layer is thus both with a fast connection, namely bonding of the insulating core with the cover layer organic adhesive, as well as a high fire protection achieved inorganic adhesive, wherein the slow curing of the inorganic adhesive is compensated for the rapid handling in the production process by the fast-curing organic adhesive and the lack of fire resistance of the organic adhesive is replaced by the high fire resistance of the inorganic adhesive.
- both adhesives are arranged in separate regions, so that on the one hand they can not be influenced chemically and on the other hand they can be arranged in the regions which are particularly suitable for the particular task of the adhesive.
- the combination of the two adhesives thus leads to a fast bond between the two material levels of the insulating core on the one hand and the. Cover layer on the other hand or between the insulating core and a fire protection plate arranged below the cover layer. This will be the economic Production of building elements allows.
- the second adhesive secures the bond in case of direct fire stress with temperatures up to more than 1000 ° C and is particularly effective in the installed state of the building element.
- the different adhesives can be applied next to each other in the form of beads or drops by spraying or rolling on the cover layers or the insulating core to be bonded thereto.
- Suitable organic adhesives have proven to be one-component or multicomponent.
- the inorganic portion of the adhesive form such adhesives that can withstand the increased temperature requirements of a fire test to over 1000 ° C and are usually based on water glass, cement, gypsum or the like.
- the individual components of the building element are joined together after application of the adhesive and cured in a continuous or discontinuous system with supplied heat.
- a usually heated double belt system or a usually heated press first reacts the organic adhesive in a short time.
- a component adhesive which sets with water during the hardening process, benefits from the water-based inorganic adhesive used in parallel.
- the building elements can already be removed from the production plant manually and mechanically for a short time after the organic adhesive has cured, and they can usually be handled.
- the inorganic adhesive cures completely in the subsequent intermediate storage of the building elements until their delivery. At this time, the building element has reached its maximum strength.
- the building elements produced in this way can already be handled after a short time, without changing the production process of the continuous or discontinuous production, in particular slowing it down.
- the inorganic adhesive ensures the necessary bond between the outer layers and the insulating core or the outer layers and arranged on the Dämmkern Brandschufizplatten even at temperature loads of about 1000 ° C, with a corresponding arrangement of two adhesives can of course also be provided between these fire protection plates and the insulating core ,
- Such building elements can therefore be processed not only in vertical alignment, but also in an inclined orientation in the building, so that hereby roof structures are created.
- the building elements described above may also have cover layers with a profiled surface.
- foaming organic adhesive are used, while the area of the cover layers, which lie directly against the insulating core, with the inorganic, non-flammable adhesive are glued to the insulating core.
- the inventive design of a building element also has the advantage that the long-term stability of such a building element is substantially improved, so that in some building elements according to the prior art to record fast aging, especially the connection between the insulating core and the outer layers does not occur a loss of overall strength is avoided. Furthermore, with the building element according to the invention, the adhesive bond between critical, for example, extremely smooth or oxidized surfaces of the cover layers can be improved.
- building element 1 for the creation of inner walls, outer walls and / or ceilings or roofs, preferably flat or slightly inclined roofs of a building consists of an insulating core forming an insulating layer 2 bound with a binder mineral fibers, especially with a synthetic resin bound rock wool and / or glass wool fibers, and at least one metallic cover layer 3, which is arranged on a large surface 4 of the insulating layer 2; wherein between the cover layer 3 and the insulating layer 2, a layer 5 is arranged consisting of two different adhesives, with which the cover layer 3 is bonded to the insulating layer 2.
- the layer 5 is divided into areas 6 and 7.
- an organic adhesive is arranged, which is formed for example as a two-component polyurethane adhesive and has a fast setting behavior.
- an inorganic adhesive is disposed in region 7, which is based on a mineral binder, such as water glass, cement, gypsum or the like, so that it has a high fire resistance and the connection between the cover layer 3 and the insulating layer 2 even at temperatures above 1000 ° C over at least a certain period guaranteed.
- the foaming trained organic adhesive is applied in the area 6 over the entire surface of the insulating layer 2 in a thickness of 1 mm, wherein on the insulating layer 2 about 0.3 kg / m 2 adhesive is arranged.
- the insulating layer 2 consists of large-sized mineral fiber boards.
- a cover layer 3 is arranged on both large surfaces 4 of the insulating layer 2, the lower cover layer 3 being single-shelled and the upper covering layer 3 being double-shelled.
- the upper cover layer thus consists of two metal shells 8, which are glued together. Between the metal shells 8, a layer 5 of two adhesives is arranged, the layer 5 corresponding to the layer 5 between the lower covering layer 3 and the insulating layer 2.
- a second embodiment of a building element 1 is shown, which differs from the embodiment of Figure 1, that on the one hand between the insulating layer and the lower cover layer 3, a fire protection plate 9, for example, a gypsum or cementitious building board is arranged and on the other hand, the upper Cover layer is formed einschalig.
- This building element 1 has three layers 5 of two adhesives, which are divided according to the embodiment of Figure 1 in areas 6 and 7. In these areas 6 and 7, in turn, an organic and an inorganic adhesive are arranged.
- the described building elements 1 have cover layers 3, which are formed as smooth sheet metal layers.
- FIG. 3 shows an exemplary embodiment with profiled sheet metal layers as cover layers 3, the sheet metal layers having beads 9.
- Alternative profiles such as microlination or other microstructures, are also useful.
- the cover layer 3 has a greater distance from the insulating layer 2.
- in this region 6 of the organic adhesive is disposed, while in the region 7 between adjacent beads 9 of a cover layer 3 inorganic adhesive is disposed.
- the sheet layers of the two outer layers 3 are made of galvanized and / or a zinc alloy having metal plates.
- sheet metal layers of light metal, in particular aluminum may be provided.
- the insulating layer 2 has a fiber profile substantially at right angles to the large surfaces 4.
- the surface 4 of the insulating layer 2 is shown as a section. It can be seen that the two adhesives are punctiform introduced into the areas 6 and 7 respectively.
- the point-like application is represented by columns 6 'and 7', respectively, wherein the columns 6 'represent the organic adhesive and the columns 7' the inorganic adhesive.
Abstract
Description
Die Erfindung betrifft ein Gebäudeelement für die Erstellung von Innenwänden, Aussenwände und/oder Decken bzw. Dächern, vorzugsweise flachen oder gering geneigten Dächern eines Gebäudes, bestehend aus einer einen Dämmkern bildenden Dämmschicht aus mit einem Bindemittel gebundenen Mineralfasern, insbesondere mit einem Kunstharz gebundenen Steinwolle- und/oder Glaswollefasern, und zumindest einer vorzugsweise metallischen Deckschicht, die auf einer großen Oberfläche der Dämmschicht angeordnet ist, wobei zwischen der Deckschicht und der Dämmschicht eine Schicht eines Klebers angeordnet ist, der die Deckschicht mit der Dämmschicht verklebt.The invention relates to a building element for the creation of interior walls, exterior walls and / or ceilings or roofs, preferably flat or slightly inclined roofs of a building, consisting of an insulating core forming insulation layer bound with a binder mineral fibers, in particular bound with a synthetic resin rockwool and / or glass wool fibers, and at least one preferably metallic cover layer, which is arranged on a large surface of the insulating layer, wherein between the cover layer and the insulating layer, a layer of an adhesive is arranged, which adheres the cover layer with the insulating layer.
Derartige Gebäudeelemente sind aus dem Stand der Technik bekannt und werden auch als Sandwichelemente bezeichnet. Sandwichelemente mit metallischen Deckschichten und einem nichtbrennbaren Dämmkern, beispielsweise aus Steinwolle, sind heute in einer Vielzahl von Varianten im Markt bekannt.Such building elements are known from the prior art and are also referred to as sandwich elements. Sandwich elements with metallic cover layers and a non-combustible insulating core, for example made of rock wool, are today known in a variety of variants in the market.
Es sind aber auch andere Sandwichelemente mit Deckschichten aus GFK (glasfaserverstärktem Kunststoff), Holzwerkstoffen, Glas usw. bekannt, bei denen die Deckschicht mit Polyurethan-Klebstoffen auf die Dämmschicht aufgeklebt werden. Aufgrund der in der Regel eingesetzten Polyurethan-Klebstoffe, die den Dämmkern mit den Deckschichten verbinden, können diese Sandwichelemente nicht in die Baustoffklasse A (nichtbrennbar) eingestuft werden, so dass sie nur die Anforderungen der Baustoffklasse B1 (schwer entflammbar) erfüllen.But there are also other sandwich panels with cover layers of fiberglass (fiberglass reinforced plastic), wood materials, glass, etc., in which the top layer with polyurethane adhesives are glued to the insulation layer. Due to the usually used polyurethane adhesives, which connect the insulation core with the outer layers, these sandwich elements can not be classified in the building material class A (non-combustible), so that they meet only the requirements of building material class B1 (flame retardant).
Derartige Sandwichelemente werden auch mit einem Dämmkern aus Polyurethan (PUR) ausgebildet, die ebenfalls in die Baustoffklasse B1 eingestuft sind, so dass es für Anwender dieser Gebäudeelemente nicht ohne weiteres erkennbar ist, welche Vorteile Gebäudeelemente mit einem Dämmkern aus Faserdämmstoffen haben. So sind Sandwichelemente mit einem Dämmkern aus Polyurethan im Gegensatz zu Sandwichelementen mit einem Kern aus Faserdämmstoffen nicht für klassifizierte Brandschutzlösungen F30 - F120 geeignet. Prüfungen der Sandwichelemente mit Dämmkernen aus Mineralfasern, insbesondere aus Steinwolle wurden inzwischen mehrfach bis zur Brandschutzklasse F120 bestanden.Such sandwich elements are also formed with an insulating core of polyurethane (PUR), which are also classified in the building material class B1, so that it is not readily apparent to users of these building elements, which advantages have building elements with an insulating core of fiber insulation. For example, sandwich panels with a polyurethane insulating core, unlike sandwich panels with a core of fiber insulation, are not suitable for classified fire protection solutions F30 - F120. Tests of the sandwich elements With insulating cores made of mineral fibers, in particular rock wool, several have now passed the fire protection class F120.
Zur Erlangung der Baustoffklasse A sind nach DIN 4102 Teil 1 sowohl der genormte Brandschachttest als auch der genormte Ofentest oder die Bestimmung des unteren Brennwertes des Bauproduktes zu bestehen. Zusätzlich wird das Bauprodukt noch auf sein Rauchfreisetzungsverhalten überprüft.In order to obtain building material class A, according to DIN 4102
Organische Kleber auf Polyurethanbasis haben sich zur Herstellung von Sandwichelementen mit einem Dämmkern aus Mineralwolle und Deckschichten aus Blechtafeln als geeignet erwiesen. Die eingesetzten Ein- bzw. ZweikomponentenKleber auf organischer Basis sichern den erforderlichen Verbund zwischen dem Dämmkern und den Deckschichten. Neben den Mineralfasern kommen als Dämmmaterial für den Dämmkern geblähte mineralische Vormaterialien, beispielsweise Perlite zum Einsatz. Auch Baustoffplatten auf Basis Gips und Zement werden gelegentlich zum Schutz eines nicht temperaturbeständigen Dämmkerns zwischen der Deckschicht und dem Dämmkern eingebaut.Polyurethane-based organic adhesives have been found to be suitable for making sandwich panels having a mineral wool insulating core and sheet metal facing layers. The one- or two-component organic-based adhesives used ensure the required bond between the insulating core and the outer layers. In addition to the mineral fibers are used as insulating material for the insulating core expanded mineral materials, such as perlites. Also building material boards based on gypsum and cement are sometimes installed to protect a non-temperature-resistant insulating core between the cover layer and the insulating core.
Die voranstehend dargestellten Sandwichelemente haben sich für die Verwendung in lotrechter Ausrichtung bewährt. Bei Deckenkonstruktionen oder geneigten Aufbauten ist aber bei derartigen Sandwichelementen zu erkennen, dass sich im Brandversuch die dem Brandherd zugewandte Deckschicht schon nach kurzer Zeit vom Dämmkern löst. Der Grund hierfür liegt darin, dass die fehlende Temperaturbeständigkeit des organischen Klebers dazu führt, dass bereits ab einer Temperatur von 100 bis 150°C dieser Kleber weich wird und bei höheren Temperaturen verbrennt, so dass der Verbund zwischen dem Dämmkern und der Deckschicht aufgelöst wird und sich die Deckschicht derart verformen kann, dass sich eine brandsichere Verbindung zwischen den einzelnen Sandwichelementen, die beispielsweise eine Deckenfläche bilden, nicht mehr gegeben ist. Hieraus resultiert ein erhöhter Temperaturdurchschlag insbesondere im Fugenbereich.The above-described sandwich elements have proven themselves for use in vertical alignment. In ceiling structures or inclined structures but can be seen in such sandwich elements that dissolves in a fire test facing the fire facing cover layer after a short time from the insulating core. The reason for this is that the lack of temperature resistance of the organic adhesive causes that already at a temperature of 100 to 150 ° C, this adhesive is soft and burns at higher temperatures, so that the bond between the insulating core and the cover layer is dissolved and the cover layer can deform such that a fireproof connection between the individual sandwich elements, which form, for example, a ceiling surface, no longer exists. This results in an increased temperature breakdown, especially in the joint area.
Es wurden daher anstelle von organischen Klebern anorganische Kleber eingesetzt, die auch Temperaturen von über 1000°C ausgesetzt werden können. Diese Kleber verbessern zwar die Langzeitfestigkeit bei Brandschutzelementen in horizontalen oder geneigten Konstruktionen, sind aber aufgrund der langen Aushärtungszeit und der beigemengten Wassermengen im Bereich der hier beschriebenen Gebäudeelemente nur bedingt einsetzbar, da sie eine kontinuierliche Fertigung, beispielsweise in einer Durchlauf-Doppelbandanlage nur bedingt ermöglichen. Bei einer rationalen kontinuierlichen Fertigung steht nämlich im Vordergrund, dass die fertiggestellten Gebäudeelemente möglichst unmittelbar nach dem Zusammenfügen ihrer Komponenten, somit des Dämmkerns und der Deckschichten handhabbar sind. Dieser schnellen Handhabbarkeit stehen die langen Aushärtungszeiten der beispielsweise auf Wasserglasbasis basierenden anorganischen Kleber entgegen. Auch Kleber auf Gips- oder Zementbasis stellen keine Altemative hierzu dar, da auch hier lange Aushärtungszeiten des Klebers in Kauf genommen werden müssen.Therefore, instead of organic adhesives, inorganic adhesives have been used which can also be exposed to temperatures of more than 1000.degree. These Although adhesives improve the long-term strength of fire protection elements in horizontal or inclined structures, but due to the long curing time and the added amounts of water in the field of building elements described here are only limited use, as they allow continuous production, for example in a continuous double belt system only conditionally. In fact, in the case of rational, continuous production, the focus is on the fact that the finished building elements can be handled as directly as possible after the joining of their components, thus of the insulating core and the cover layers. This fast handling is counteracted by the long curing times of, for example, based on water glass based inorganic adhesive. Gypsum or cement-based adhesives are also not an alternative, since long curing times of the adhesive must also be taken into account here.
Werden derart verklebte Gebäudeelemente zu früh angehoben, besteht die nicht unerhebliche Gefahr, dass sich einige oder eine Vielzahl von Klebepunkten lösen, die die Endfestigkeit derartiger Gebäudeelemente nachteilig beeinflussen.If so glued building elements raised too early, there is the considerable risk that solve some or a variety of adhesive points that adversely affect the ultimate strength of such building elements.
Der Erfindung liegt daher die Aufgabe zugrunde, ein gattungsgemäßes Gebäudeelement derart weiterzuentwickeln, dass eine schnelle Handhabung der fertiggestellten Gebäudeelemente am Ende einer kontinuierlichen Fertigung bei gleichzeitig hohem Brandschutz möglich ist, so dass die Gebäudeelemente auch im Dachbereich mit größeren Neigungswinkeln eingesetzt werden können.The invention is therefore based on the object to further develop a generic building element such that a quick handling of the finished building elements at the end of a continuous production with high fire protection is possible, so that the building elements can also be used in the roof area with larger angles of inclination.
Die Lösung dieser Aufgabenstellung sieht bei einem gattungsgemäßen Gebäudeelement vor, dass die Schicht aus einem ersten schnell abbindenden Kleber und einem zweiten, bei direkter Brandeinwirkung mit Temperaturen bis über 1.000° C wirksamen Kleber besteht, die in voneinander getrennten Bereichen der Schicht angeordnet sind.The solution of this problem provides for a generic building element, that the layer consists of a first fast-setting adhesive and a second, effective in direct fire exposure with temperatures up to about 1000 ° C adhesive, which are arranged in separate regions of the layer.
Die Verbindung zwischen dem Dämmkern und der Deckschicht wird somit sowohl mit einem die schnelle Verbindung, nämlich Verklebung des Dämmkerns mit der Deckschicht erzielenden organischen Kleber, als auch einem einen hohen Brandschutz gewährleistenden anorganischen Kleber erzielt, wobei die langsame Aushärtung des anorganischen Klebers hinsichtlich der schnellen Handhabbarkeit im Produktionsprozess durch den schnell aushärtenden organischen Kleber kompensiert wird und die mangelnde Brandfestigkeit des organischen Klebers durch die hohe Brandfestigkeit des anorganischen Klebers ersetzt wird. Beide Kleber sind darüber hinaus in voneinander getrennten Bereichen angeordnet, so dass sie sich einerseits chemisch nicht beeinflussen und andererseits in den Bereichen angeordneten werden können, die für die jeweilige Aufgabe der Kleber besonders geeignet sind.The connection between the insulating core and the cover layer is thus both with a fast connection, namely bonding of the insulating core with the cover layer organic adhesive, as well as a high fire protection achieved inorganic adhesive, wherein the slow curing of the inorganic adhesive is compensated for the rapid handling in the production process by the fast-curing organic adhesive and the lack of fire resistance of the organic adhesive is replaced by the high fire resistance of the inorganic adhesive. Moreover, both adhesives are arranged in separate regions, so that on the one hand they can not be influenced chemically and on the other hand they can be arranged in the regions which are particularly suitable for the particular task of the adhesive.
Weitere Merkmale und Vorteile der Erfindung ergeben sich aus den Unteranprüchen und werden nachfolgend erläutert.Further features and advantages of the invention will become apparent from the Unteranprüchen and are explained below.
Zur Herstellung eines nichtbrennbaren Gebäudeelementes mit metallischen Deckschichten und einem Dämmkern aus Steinwolle können heute Dämmplatten verwendet werden, die geringste Dickentoleranzen aufweisen. Glatte metallische Deckschichten in Form von Blechen gewährleisten ein vollflächiges Aufliegen auf dem normalerweise unkaschierten nichtbrennbaren Dämmkern aus Steinwollefasem. Werden profilierte Bleche verwendet (Sickengeometrie, Mikrolinierungen, Mikrostrukturen) so ist es vorteilhaft, den Abstand zwischen der Deckschicht und der Oberfläche des Dämmkerns an keiner Stelle größer als 1,1 mm auszubilden.To produce a non-combustible building element with metallic cover layers and an insulating core of rock wool today insulation boards can be used, which have the smallest thickness tolerances. Smooth metallic cover layers in the form of metal sheets ensure full contact with the normally non-laminated non-combustible insulating core of rockwool fibers. If profiled sheets are used (bead geometry, microlining, microstructures), it is advantageous to form the distance between the cover layer and the surface of the insulating core at any point greater than 1.1 mm.
Mit derartigen Gebäudeelementen können ergänzende Anwendungen im Gebäudebau, insbesondere im Industriehallenbau erschlossen werden, die bislang aufgrund der Einstufung in die Baustoffklasse B1 nicht erreicht wurden. Beispiele sind nichtbrennbar ausgeschriebene Trennwände oder Fassaden, Brandwände, Komplextrennwände und nichtbrennbare Dachkonstruktionen mit dem erfindungsgemäßen Gebäudeelement herstellbar.With such building elements complementary applications in building construction, especially in industrial halls can be developed, which were previously not achieved due to the classification in the building material class B1. Examples are non-combustible tendered partitions or facades, firewalls, complex partitions and non-combustible roof structures with the building element according to the invention produced.
Die Kombination der beiden Kleber führt somit zu einem schnellen Verbund zwischen den beiden Werkstoffebenen des Dämmkerns einerseits und der. Deckschicht andererseits bzw. zwischen dem Dämmkern und einer unterhalb der Deckschicht angeordneten Brandschutzplatte. Hierdurch wird die wirtschaftliche Herstellung der Gebäudeelemente ermöglicht. Der zweite Kleber sichert bei direkter Brandbeanspruchung mit Temperaturen bis über 1000°C den Haftverbund und wirkt insbesondere im eingebauten Zustand des Gebäudeelementes.The combination of the two adhesives thus leads to a fast bond between the two material levels of the insulating core on the one hand and the. Cover layer on the other hand or between the insulating core and a fire protection plate arranged below the cover layer. This will be the economic Production of building elements allows. The second adhesive secures the bond in case of direct fire stress with temperatures up to more than 1000 ° C and is particularly effective in the installed state of the building element.
Die unterschiedlichen Kleber können in Form von Raupen oder Tropfen im Sprüh- oder Walzenverfahren nebeneinander auf die Deckschichten oder den damit zu verklebenden Dämmkern aufgetragen werden.The different adhesives can be applied next to each other in the form of beads or drops by spraying or rolling on the cover layers or the insulating core to be bonded thereto.
Als geeignete organische Kleber haben sich solche auf ein- oder mehrkomponentiger Basis erwiesen. Den anorganischen Anteil der Kleber bilden solche Kleber, die den erhöhten Temperaturanforderungen eines Brandversuches bis über 1000°C Stand halten können und in der Regel auf Wasserglas, Zement, Gips oder dergleichen basieren.Suitable organic adhesives have proven to be one-component or multicomponent. The inorganic portion of the adhesive form such adhesives that can withstand the increased temperature requirements of a fire test to over 1000 ° C and are usually based on water glass, cement, gypsum or the like.
Die einzelnen Bestandteile des Gebäudeelementes werden nach Auftrag der Kleber zusammengefügt und in einer kontinuierlichen bzw. diskontinuierlichen Anlage mit zugeführter Wärme ausgehärtet. In einer üblicherweise beheizten Doppelbandanlage oder einer üblicherweise beheizten Presse reagiert zunächst der organische Kleber in kurzer Zeit. Hierbei profitieren ein Komponentenkleber, die mit Wasser abbinden während des Härtevorgangs vom parallel eingesetzten wasserhaltigen anorganischen Kleber. Durch den zeitlich sehr kurzen Abbindevorgang des organischen Klebers können die Gebäudeelemente bereits kurze Zeit nach dem Aushärten des organischen Klebers manuell oder maschinell aus der Produktionsanlage entnommen und in üblicherweise gehandhabt werden. Der anorganische Kleber härtet in der anschließenden Zwischenlagerung der Gebäudeelemente bis zu ihrer Auslieferung vollständig aus. Zu diesem Zeitpunkt hat das Gebäudeelement seine maximale Festigkeit erreicht.The individual components of the building element are joined together after application of the adhesive and cured in a continuous or discontinuous system with supplied heat. In a usually heated double belt system or a usually heated press first reacts the organic adhesive in a short time. A component adhesive, which sets with water during the hardening process, benefits from the water-based inorganic adhesive used in parallel. As a result of the very short setting process of the organic adhesive, the building elements can already be removed from the production plant manually and mechanically for a short time after the organic adhesive has cured, and they can usually be handled. The inorganic adhesive cures completely in the subsequent intermediate storage of the building elements until their delivery. At this time, the building element has reached its maximum strength.
Die derart hergestellten Gebäudeelemente sind trotz des Einsatzes eines anorganischen Klebers schon nach kurzer Zeit handhabbar, ohne den Produktionsablauf der kontinuierlichen bzw. diskontinuierlichen Fertigung zu ändern, insbesondere zu verlangsamen.Despite the use of an inorganic adhesive, the building elements produced in this way can already be handled after a short time, without changing the production process of the continuous or discontinuous production, in particular slowing it down.
Im Brandversuch und bei Realbränden wird sich nur der organische Kleber lösen oder verbrennen. Der anorganische Kleber sichert auch bei Temperaturbelastungen von über 1000°C den notwendigen Verbund zwischen den Deckschichten und dem Dämmkern bzw. den Deckschichten und auf dem Dämmkern angeordneten Brandschufizplatten, wobei eine entsprechende Anordnung von zwei Klebern selbstverständlich auch zwischen diesen Brandschutzplatten und dem Dämmkern vorgesehen sein kann. Derartige Gebäudeelemente können daher nicht nur in lotrechter Ausrichtung, sondern auch in geneigter Ausrichtung im Gebäude verarbeitet werden, so dass hiermit auch Dachkonstruktionen erstellbar sind.In fire tests and in real fires, only the organic adhesive will dissolve or burn. The inorganic adhesive ensures the necessary bond between the outer layers and the insulating core or the outer layers and arranged on the Dämmkern Brandschufizplatten even at temperature loads of about 1000 ° C, with a corresponding arrangement of two adhesives can of course also be provided between these fire protection plates and the insulating core , Such building elements can therefore be processed not only in vertical alignment, but also in an inclined orientation in the building, so that hereby roof structures are created.
Die voranstehend beschriebenen Gebäudeelemente können auch Deckschichten mit profilierter Oberfläche aufweisen. Bei derartigen Gebäudeelementen hat es sich als vorteilhaft erwiesen, dass in den Bereichen, in denen durch das Aufbringen der profilierten Deckschichten Hohlräume zum Dämmkern entstehen, aufschäumende organische Kleber eingesetzt werden, während die Bereich der Deckschichten, die unmittelbar am Dämmkern anliegen, mit dem anorganische, nicht brennbaren Kleber mit dem Dämmkern verklebt sind.The building elements described above may also have cover layers with a profiled surface. In such building elements, it has proven to be advantageous that in the areas in which arise by applying the profiled cover layers cavities to the insulating core, foaming organic adhesive are used, while the area of the cover layers, which lie directly against the insulating core, with the inorganic, non-flammable adhesive are glued to the insulating core.
Die erfindungsgemäße Ausgestaltung eines Gebäudeelementes hat darüber hinaus den Vorteil, dass die Langzeitstabilität eines derartigen Gebäudeelementes wesentlich verbessert wird, so dass die teilweise bei Gebäudeelementen nach dem Stand der Technik zu verzeichnende schnelle Alterung, insbesondere der Verbindung zwischen dem Dämmkern und den Deckschichten nicht auftritt, wodurch ein Verlust der Gesamtfestigkeit vermieden wird. Ferner kann mit dem erfindungsgemäßen Gebäudeelement der Haftverbund zwischen kritischen, beispielsweise extrem glatten oder oxidierten Flächen der Deckschichten verbessert werden.The inventive design of a building element also has the advantage that the long-term stability of such a building element is substantially improved, so that in some building elements according to the prior art to record fast aging, especially the connection between the insulating core and the outer layers does not occur a loss of overall strength is avoided. Furthermore, with the building element according to the invention, the adhesive bond between critical, for example, extremely smooth or oxidized surfaces of the cover layers can be improved.
