Description

Die Erfindung betrifft ein plattenförmiges Bauelement für Wände mit die äußeren Elementflächen bedeckenden Außenplatten, zwischen denen eine Füllung ist und mit einem die Außenplatten je an einer und derselben Bauelementstirnseite verbindenden Randprofil, das jeweils zwei zu der betreffenden Bauelementstirnseite hin offene, an beiden Rändern dieser Elementenstirnseite liegende Nuten bildet zur Aufnahme der Außenplattenränder eines benachbarten Bauelementes, wobei sich zwischen diesen Nuten ein ganz oder zum größten Teil ringsum geschlossener Hohlprofilraum befindet.The invention relates to a plate-shaped component for walls with outer panels covering the outer element surfaces, between which there is a filling and with an edge profile connecting the outer panels on one and the same component end face, each with two open to the relevant component end face, lying on both edges of this element end face Grooves form for receiving the outer plate edges of an adjacent component, a completely or for the most part enclosed hollow profile space between these grooves.

Ein solches Bauelement ist z.B. aus der DE-A 2 754 814 und der DE-A 3 104 735 bekannt. Die Lage der Profile ist hierbei nur durch die Außenplatten und die Füllung bestimmt. Dies erwies sich als unzulänglich, wenn mehrere Profile in dasselbe Bauelement angeordnet sind und die Lage gegenüber einander sehr exakt und fest sein soll.Such a component is e.g. known from DE-A 2 754 814 and DE-A 3 104 735. The position of the profiles is only determined by the outer panels and the filling. This turned out to be inadequate if several profiles are arranged in the same component and the position relative to one another should be very precise and firm.

Aufgabe der Erfindung ist es, ein Bauelement der eingangs genannten Art so zu verbessern, daß eine exakte und sichere Lage der Profile gegenüber dem gesamten Bauelement als auch gegenüber weiteren Profilen desselben Bauelementes stets gegeben ist.The object of the invention is to improve a component of the type mentioned in such a way that there is always an exact and secure position of the profiles with respect to the entire component and also with respect to other profiles of the same component.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Verbindung der beiden Außenplatten an einer Stirnseite von mehreren aneinanderstoßenden Profilen gebildet wird, die miteinander durch einen gemeinsamen Profilabschnitt verbunden sind, der in einander zugekehrten Enden von Längskanälen der Profile einliegt, die an der der Füllung zugewandten Seite der Hohlprofilräume angeordnet und zur Füllung hin offen sind und über den nicht vom Profilabschnitt eingenommenen Abschnitten der Längskanäle mit Füllungsmaterial ausgefüllt sind.This object is achieved in that the connection of the two outer plates is formed on one end face by a plurality of abutting profiles, which are connected to one another by a common profile section, which lies in mutually facing ends of longitudinal channels of the profiles, on the side facing the filling the hollow profile spaces are arranged and open towards the filling and are filled with filling material over the sections of the longitudinal channels not occupied by the profile section.

In einen solchen Längskanal können z.B. streifenförmige Profilabschnitte gesteckt werden, um hierüber zwei Profile stirnseitig miteinander zu verbinden. Dies führt zu genauen und festen Verbindungen der Profile miteinander, wenn mehrere Profile an z.B. einer Bauelementenstirnseite aneinander befestigt sind. Auch kann eine Verbindung der Profile vor der Montage erfolgen.In such a longitudinal channel e.g. strip-shaped profile sections are inserted in order to connect two profiles with each other at the end. This leads to precise and firm connections of the profiles to each other, if several profiles on e.g. a component face are attached to each other. The profiles can also be connected before assembly.

Ein sicherer Halt des Profilabschnitts ist dann gegeben, wenn der Längskanal zwei seitliche hinterschnittene, innere Längsnuten bildet. Auch ist es von Vorteil, wenn an jeder von zwei aneinander anschließenden Stirnseiten ein Profil vorgesehen ist. Besonders vorteilhaft ist es, wenn jede hinterschnittene Längsnut an der der Füllung zugewandten Seite durch zungenartige Bereiche begrenzt ist, die zum Längskanalinneren schräg angeordnet sind, um den Profilabschnitt klemmend aufzunehmen.The profile section is held securely when the longitudinal channel forms two lateral, undercut, inner longitudinal grooves. It is also advantageous if a profile is provided on each of two adjoining end faces. It is particularly advantageous if each undercut longitudinal groove is delimited on the side facing the filling by tongue-like areas which are arranged obliquely to the interior of the longitudinal channel in order to receive the profile section by clamping.

Um sicherzustellen, daß der Profilabschnitt bei axial zueinander zu verbindenden Profilen in den Längskanal zu tief hineinrutscht, wird vorgeschlagen, daß der Profilabschnitt zumindest etwa mittig oder mittig auf einer seiner vom Längskanal übergriffenen Längsflächen einen sägezahnförmigen Vorsprung aufweist, an den eines der Profilenden insbesondere mit dem Ende eines Längkanals zur Anlage gelangt. Hierbei ist es von Vorteil, wenn auf beiden Hälften des Profilabschnitts weitere Vorsprünge angeordnet sind, die sägezahnförmig und/oder dachförmig sind und welche mit einer Innenfläche des Längskanals Haftreibung ergeben. Der Formschluß wird dadurch erhöht, daß zwischen zwei Längsrändern einer Flachseite, die von den zwei einwärts gekehrten Bereichen des Längskanals übergriffen werden, eine leistenförmige Erhebung vorsteht. Die Profilabschnitte lassen sich leicht hineinstecken, wenn beide Enden des Profilabschnitts abgerundet sind.In order to ensure that the profile section slides too deeply into the longitudinal channel in the case of profiles to be connected to one another axially, it is proposed that the profile section have a sawtooth-shaped projection, at least approximately in the middle or center of one of its longitudinal surfaces overlapped by the longitudinal channel, to which one of the profile ends in particular with the End of a longitudinal channel to the system. It is advantageous here if further projections are arranged on both halves of the profile section, which are sawtooth-shaped and / or roof-shaped and which produce static friction with an inner surface of the longitudinal channel. The positive engagement is increased in that a strip-like elevation projects between two longitudinal edges of a flat side, which are overlapped by the two inwardly facing regions of the longitudinal channel. The profile sections can be easily inserted when both ends of the profile section are rounded.

Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt und werden im folgenden näher beschrieben. Es zeigen:

  • Figur 1 einen Querschnitt durch den Verbindungsbereich zweier stirnseitig miteinander verbundener Bauelemente,
  • Figur 2 in perspektivischer Darstellung die Enden zweier Profile, die miteinander fluchtend durch einen in beide Profile einliegenden Profilabschnitt verbunden werden,
  • Figur 3 eine stirnseitige Ansicht von einem Profil, mit einem darin einliegenden Profilabschnitt,
  • Figur 4 eine perspektivische Ansicht des Profilabschnitts,
  • Figur 5 eine Seitenansicht eines mittleren Teils des Profilabschnitts ausschnittsweise.
Embodiments of the invention are shown in the drawings and are described in more detail below. Show it:
  • FIG. 1 shows a cross section through the connection area of two components connected to one another on the end face,
  • FIG. 2 shows a perspective representation of the ends of two profiles which are connected in alignment with one another by a profile section lying in both profiles,
  • FIG. 3 shows an end view of a profile, with a profile section lying therein,
  • FIG. 4 shows a perspective view of the profile section,
  • Figure 5 is a side view of a central part of the profile section in sections.

Jedes plattenförmige Bauelement 1 ist an beiden Außenflächen durch Außenplatten 2 vollständig bedeckt. Der zwischen den Platten 2 befindliche Bereich ist mit einer Füllung 3, insbesondere aus Schaumstoff, versehen, und zumindest an einem Rand des Bauelements 1 ist stirnseitig ein Profil 4 zwischen die Außenplatten 2 eingefügt, an dem rückseitig die Füllung 3 angrenzt.Each plate-shaped component 1 is completely covered on both outer surfaces by outer plates 2. The area between the plates 2 is provided with a filling 3, in particular made of foam, and at least on one edge of the component 1, a profile 4 is inserted on the front side between the outer plates 2, on the back of which the filling 3 is adjacent.

Die Profile 4 weisen jeweils zwei zu der Bauelementenstirnseite hin offene Nuten 5 auf, die jeweils nahe einer Außenplatte 2 liegen, so daß im Querschnitt beidseitig des Profils eine Nut 5 vorgesehen ist. Auf der Bauelementenseite, an der das Profil 4 befestigt ist, sind die Außenplatten 2 mit ihren Rändern nach innen in die Nut 5 umgebogen und bilden hier somit Umbördelungen 11.The profiles 4 each have two grooves 5 which are open towards the component end face and which are each close to an outer plate 2, so that a groove 5 is provided on both sides of the profile in cross section. On the component side to which the profile 4 is fastened, the outer plates 2 are bent with their edges inwards into the groove 5 and thus form flanges 11 here.

Der Bereich zwischen den Nuten wird von einem rechteckförmigen oder quadratischen Hohlprofil 6 gebildet, das an den übrigen Profilteilen, insbesondere den Rändern der Nut 5 angeformt ist.The area between the grooves is formed by a rectangular or square hollow profile 6, which is molded onto the other profile parts, in particular the edges of the groove 5.

In die beiden Nuten 5 dringen die Ränder 2a der Außenplatte 2 eines benachbarten Bauelements 1 ein, wenn zwei Bauelemente miteinander verbunden werden. Hierbei liegen die Innenseiten der Außenplatten 2 des benachbarten Bauelements an den Au- βenseiten des Hohlprofils 6 an. Diese Ränder 2a liegen aufgrund einer Z-förmigen Zweifachkantung der Außenplatte 2 tiefer im Bauelement 1, so daß zwischen den Außenseiten der Ränder 2a und dem äu- βeren Profilteil 4a des Profils 4 sich innerhalb der Nut 5 ein Spalt bildet, in den Befestigungsklammern 7 einschiebbar sind.The edges 2a of the outer plate 2 of an adjacent component 1 penetrate into the two grooves 5 when two components are connected to one another. In this case, the inner sides of the outer plates 2 of the adjacent component abut the outer sides of the hollow profile 6. These edges 2a are due to a Z-shaped double edging of the outer plate 2 deeper in the component 1, so that between the outer sides of the edges 2a and the outer profile part 4a of the profile 4 a gap forms within the groove 5, can be inserted into the fastening clips 7 are.

Auf der der Füllung zugewandten Rückseite des Profils 4 ist ein Längskanal 8 eingeformt, der über einen Teil seiner Breite zur Füllung 3 hin offen ist und damit zu beiden Seiten hinterschnittene Längsnuten 9 aufweist. Ist dieser Längskanal 8 von dem Material der Füllung 3 durchdrungen, so klammern sich die Längsnuten 9 in das Material der Füllung 3, um damit einen zusätzlichen Halt in der Füllung zu bieten.On the back of the profile 4 facing the filling, a longitudinal channel 8 is formed which is open to the filling 3 over part of its width and thus has undercut longitudinal grooves 9 on both sides. If this longitudinal channel 8 is penetrated by the material of the filling 3, the longitudinal grooves 9 cling to the material of the filling 3 in order to offer an additional hold in the filling.

Sollen zwei oder mehrere Profile an einer Stirnseite eines Bauelementes miteinander axial verbunden werden, so werden in den Längskanal 8 Profilabschnitte 10 aus handelsüblichem Streifenmaterial eingeschoben, wobei sie jeweils zur Hälfte in einem ersten Profil 4 und in einem zweiten Profil 4 einliegen und damit diesen zueinander Halt geben.If two or more profiles are to be axially connected to one another on one end face of a component, then 8 profile sections 10 made of commercially available strip material are inserted into the longitudinal channel, half of which lie in a first profile 4 and in a second profile 4 and thus hold them together give.

In einem Ausführungsbeispiel nach den Figuren 3 bis 5 besitzt der Profilabschnitt 20 zu beiden Längsseiten auf der Flachseite je einen Längsrand, der unter die zungenförmigen, einwärtsgerichteten Bereich 12 des Längskanals 8 jeweils klemmend einliegt. Diese Längsränder 21,22 weisen auf einer Hälfte sägezahnförmige Vorsprünge 25 bzw. Erhebungen auf, die Anschlagsflächen für das Ende des Längskanals 8 bilden. Auf der anderen Hälfte sind dachförmige Erhebungen 24, die die Klemmkraft bzw. Reihung im anderen Profil 4 erhöhen.In an exemplary embodiment according to FIGS. 3 to 5, the profile section 20 has a longitudinal edge on both flat sides on the flat side, which is clamped under the tongue-shaped, inward-facing region 12 of the longitudinal channel 8. On one half, these longitudinal edges 21, 22 have sawtooth-shaped projections 25 or elevations, which form stop surfaces for the end of the longitudinal channel 8. On the other half are roof-shaped elevations 24, which increase the clamping force or sequence in the other profile 4.

Zwischen den Längsrändern 21, 22 befindet sich auf derselben Flachseite eine Längserhebung 23, die zwischen den Zungen 12 eingliegt. An beiden Enden ist der Profilabschnitt 20 abgerundet.Between the longitudinal edges 21, 22 there is a longitudinal elevation 23 on the same flat side, which lies between the tongues 12. The profile section 20 is rounded at both ends.
