- the composite element has two mutually parallel cover layers 1, 2.
- Hard foam 3, in particular polyurethane and polyisocyanate, is introduced between the two cover layers and adheres to the inside of the cover layers.

- the inside of the edge profiles 4 is also filled with hard foam 3, which ensures the shape stability of the edge areas under load.
- Both legs 5 of each profile 4 form outwardly open grooves 6a, 6b which run in the longitudinal direction of the profile 4.
- the groove 6a arranged on the inside of the element is trapezoidal in cross section and is connected by the lower cover layer 1.
- the opposite outer groove 6b is dovetail-shaped in cross section and is uncovered on the outside, since the cover layer 2 engages in it with a bevel.
- the described function of the edge profiles is particularly guaranteed even when out the top layer 2 is dispensed with for special application-technical reasons.
- Both grooves 6a, 6b are delimited by leg regions 7a, 7b, which lie at the same height and are therefore flush with one another and with the cover layer 1. Due to the same height of the leg regions 7a, 7b, the edge profile 4 has the same thickness in the region of both leg regions.
- the base region 8 of the edge profile 4 between the legs 5 forms an outwardly projecting spring 9 in all of the two edge profiles, which extends in the longitudinal direction of the profile 4 and lies approximately centrally between the legs 5.
- the opposite edge profile 4 forms a groove 10 in the base region 8, which also extends in the longitudinal direction and lies centrally between the legs 5.
- the internal dimensions of the groove 10 correspond approximately to the external dimensions of the tongue 9, so that the tongue 9 is inserted in the groove 10 of an adjacent composite element.
- the two surfaces of the base region 8 on both sides of the tongue 9 or the groove 10 are offset from one another and parallel to create space for insert parts.
- such an offset arrangement is not absolutely necessary.
Abstract
Description
Die Erfindung betrifft ein plattenförmiges Verbundelement für Bauzwecke mit zwei seitlichen zueinander parallelen Deckschichten und an den Längskanten angeordneten Randprofilen, die im Querschnitt U-förmig sind, deren Schenkel gegeneinander gerichtet sind und die die Ränder der Deckschichten tragen, wobei der Raum zwischen den Deckschichten und das Innere der Randprofile mit Hartschaum ausgefüllt ist und die Schenkel nach außen offene, zu den Elementaußenkanten parallele Nuten bilden.The invention relates to a plate-shaped composite element for construction purposes with two lateral cover layers parallel to each other and arranged on the longitudinal edges edge profiles, which are U-shaped in cross section, the legs of which are directed towards each other and which carry the edges of the cover layers, the space between the cover layers and the The inside of the edge profiles is filled with hard foam and the legs form grooves that are open to the outside and parallel to the outer edges of the element.
Aus der deutschen Offenlegungsschrift 34 45 895 sind solche Verbundelemente bekannt. Die in den Schenkeln der Randprofile angeordneten Nuten sind hierbei von zwei Schenkelbereichen begrenzt, die in verschiedenen Höhen liegen, d.h. der der Profilbasis nähere Schenkelbereich ragt weniger weit nach außen vor als der das freie Schenkelende bildende äußere Schenkelbereich. Liegt ein solches.Verbundelement mit seiner Seitenfläche auf einem Bauteil auf, das auf das Verbundelement eine Last überträgt oder aufnimmt, so kommt es zumindest im Bereich der Randprofile zu einem Verdrehen und zu einer Formänderung der Randbereiche des Verbundelements, da die inneren Schenkelbereiche an dem die Last ausübenden Element nicht anliegen, sondern hierzu einen Abstand bilden. Ein solches Verdrehen des Randprofils führt zu erheblichen inneren Kräften innerhalb des Verbundelements und zu einem vorzeitigen Abreißen des Hartschaums an den Innenseiten des Randprofils, so daß die Tragfähigkeit wesentlich verringert wird.Such composite elements are known from German Offenlegungsschrift 34 45 895. The grooves arranged in the legs of the edge profiles are limited here by two leg regions which lie at different heights, ie the leg region closer to the profile base projects less far outwards than the outer leg region forming the free leg end. If such a composite element rests with its side face on a component that transmits or absorbs a load on the composite element, then at least in the area of the edge profiles there is a twisting and a change in shape of the edge areas of the composite element, since the inner leg areas on which the Load exercising element not in contact, but form a distance from it. Such a twisting of the edge profile leads to considerable internal forces within the composite element and to premature tearing off of the hard foam on the inside of the edge profile, so that the load-bearing capacity is significantly reduced.
Dieser Abstand kann zwar dazu benutzt werden, daß über die Randprofile stirnseitig zusätzliche U-Profile aufgeschoben werden, um die Stabilität des Verbundelements zu erhöhen, aber dies ist nicht nur konstruktiv aufwendig, sondern führt auch zu Bildung von Wärmebrücken und zu Abdichtungsproblemen.Although this distance can be used to push additional U-profiles over the end profiles to increase the stability of the composite element, this is not only structurally complex, but also leads to the formation of thermal bridges and sealing problems.
Aufgabe der Erfindung ist es, ein Verbundelement der eingangs genannten Art so zu verbessern, daß besonders im Bereich der Randprofile eine maximale Tragfähigkeit und Formstabilität des Verbundelementes gegeben ist.The object of the invention is to improve a composite element of the type mentioned in such a way that, particularly in the area of the edge profiles, there is maximum load-bearing capacity and dimensional stability of the composite element.
Diese Aufgabe wird erfindungsgemäß auch dadurch gelöst, daß die an die jeweilige Nut anschließenden Bereiche der Schenkel miteinander fluchten und mit dem breiten Mittelgurt des Elementes fluchten.This object is also achieved according to the invention in that the regions of the legs adjoining the respective groove are in alignment with one another and in alignment with the wide central belt of the element.
Ein solches Verbundelement kann vollflächig auf einem die Kräfte übernehmenden Tragwerkselement anliegen, so daß diese Kräfte nicht dazu führen, daß sich das Verbundelement im Bereich der Randprofile verdrehen und verziehen kann. Der Hartschaum bleibt sicher an der Innenseite des Randprofils haften und zusätzliche verstärkende Profile sind nicht erforderlich. Ferner sind die Randprofile einfacherer in der Herstellung.Such a composite element can rest over the full area on a structural element which takes over the forces, so that these forces do not lead to the composite element being able to twist and distort in the region of the edge profiles. The hard foam sticks securely to the inside of the edge profile and additional reinforcing profiles are not necessary. Furthermore, the edge profiles are easier to manufacture.
Besonders vorteilhaft ist es, wenn der die Schenkel verbindende Basisbereich eines stirnseitigen Randprofils eine nach außen vorspringende Feder bildet, die in Längsrichtung des Profils verläuft und das parallele Randprofil der anderen Stirnseite eine nach innen gerichtete, in Profillängsrichtung verlaufende Nut bildet, die die Feder des angrenzenden Verbundelementes aufnimmt. Diese Nut-Federverbindung verbessert nicht nur die Abdichtung, sondern verhindert zusätzlich ein Verdrehen der Randbereiche.It when the base region connecting the legs of an end edge profile forms an outwardly projecting spring is particularly advantageous, which in The longitudinal direction of the profile runs and the parallel edge profile of the other end face forms an inwardly directed groove running in the longitudinal direction of the profile, which receives the tongue of the adjacent composite element. This tongue and groove connection not only improves the sealing, but also prevents the edge areas from twisting.
Ein Ausführungsbeispiel der Erfindung ist in einem waagerechten Schnitt durch das Verbundelement in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in a horizontal section through the composite element in the drawing and will be described in more detail below.
Das Verbundelement weist zwei zueinander parallele Deckschichten 1, 2 auf. Zwischen den beiden Deckschichten ist Hartschaum 3, insbesondere Polyurethan und Polyisocyanat eingebracht, der an den Innenseiten der Deckschichten haftet.The composite element has two mutually
Die senkrechten Stirnseiten des Verbundelements sind durch Randprofile 4 aus Metall verschlossen, deren Querschnitt im wesentlichen U-förmig ist, wobei die beiden Schenkel 5 des Profils 4 zum gegenüberliegenden Randprofil weisen. Das Innere der Randprofile 4 ist auch durch Hartschaum 3 ausgefüllt, der die Formstabilität der Randbereiche unter Last gewährleistet.The vertical end faces of the composite element are closed by
Beide Schenkel 5 jeden Profils 4 bilden nach außen hin offene Nuten 6a, 6b die in Längsrichtung des Profils 4 verlaufen. Die an die Elementinnenseite angeordnete Nut 6a ist im Querschnitt trapezförmig und wird durch die untere Deckschicht 1 verbunden. Die gegenüberliegende äußere Nut 6b ist im Querschnitt schwalbenschwanzförmig und ist nach außen hin unbedeckt, da die Deckschicht 2 mit einer Abkantung in diese eingreift. Die beschriebene Funktion der Randprofile ist insbesondere auch dann gewährleistet, wenn aus besonderen anwendungstechnischen Gründen auf die Deckschicht 2 verzichtet wird.Both
Beide Nuten 6a, 6b sind von Schenkelbereichen 7a, 7b begrenzt, die in gleicher Höhe liegen und somit miteinander und mit der Deckschicht 1 fluchten. Aufgrund der gleichen Höhe der Schenkelbereiche 7a, 7b weist das Randprofil 4 im Bereich beider Schenkelbereiche dieselbe Dicke auf.Both
Der Basisbereich 8 des Randprofils 4 zwischen den Schenkeln 5 bildet bei allen der beiden Randprofile eine nach außen vorspringende Feder 9, die in Längsrichtung des Profils 4 verläuft und etwa mittig zwischen den Schenkel 5 liegt. Das gegenüberliegende Randprofil 4 bildet im Basisbereich 8 eine Nut 10, die auch in Längsrichtung verläuft und mittig zwischen den Schenkeln 5 liegt. Die Innenabmessungen der Nut 10 entsprechen etwa den Außenabmessungen der Feder 9, so daß die Feder 9 in der Nut 10 eines benachbarten Verbundelements zur Einlage gelangt.The
Die beiden Flächen des Basisbereichs 8 zu beiden Seiten der Feder 9 bzw. der Nut 10 liegen im Ausführungsbeispiel zueinander versetzt und parallel, um Raum für Einlegeteile zu schaffen. Eine solche versetzte Anordnung ist aber nicht unbedingt erforderlich.In the exemplary embodiment, the two surfaces of the
