Abstract

The invention relates to a building element with connecting elements or connecting profiles on its lateral end faces, which elements or profiles run along or parallel to its outer or inner face, are positive and composed in particular of metal and which are connected by means of limbs in the region of the end-face portion of the building element to the latter, wherein at least one of the limbs (e.g. anchoring limb of the connecting profile), surrounded on both sides or on its two flat faces by the material of the building element, is sealed firmly inside the end-face region or portion in such a way that it projects into the latter, and is anchored in such a way that it is embedded therein.

Description

Die Erfindung betrifft einen Formstein mit längs bzw. parallel zu seiner Außen- bzw. Innenfläche verlaufenden, formschlüssigen und insbesondere aus Metall bestehenden Verbindungselementen bzw. Verbindungsprofilen an seinen seitlichen Stirnflächen, welche mittels Schenkeln im Bereich des Endseitenabschnitts des Formsteins mit die­sem verbunden sind.The invention relates to a molded block with longitudinally or parallel to its outer or inner surface, positive and in particular made of metal connecting elements or connecting profiles on its lateral end faces, which are connected by means of legs in the region of the end side section of the molded block.

Bei einem bekannten Formstein mit endseitigen Verbin­dungsprofilen sind deren seitliche Schenkel beidseitig auf den Außenflächen des Formsteins aufliegend ange­ordnet, wodurch das Verbindungsprofil in sich ent­sprechend selbsttragend formsteif ausgebildet sein muß, damit sie am Formstein halten und z. B. nicht abgebogen werden können. Außerdem ist das bekannte Verbindungs­profil auf der Außenseite direkt der Korrosion aus­gesetzt. Auch ist es schwierig, auf den Schenkelaußen­seiten einen gut haltbaren Verputz zu gewährleisten.In a known molded block with connecting profiles at the ends, the lateral legs are arranged on both sides to rest on the outer surfaces of the molded block, as a result of which the connecting profile must be designed to be inherently self-supporting in order to hold it on the molded block and e.g. B. cannot be turned. In addition, the known connection profile on the outside is directly exposed to corrosion. It is also difficult to ensure a durable plaster on the outside of the legs.

Aufgabe der Erfindung ist die Schaffung eines vorzugs­weise leichtgewichtigen Formsteins mit stirnseitigen Verbindungsprofilen, welcher mit den Verbindungsprofilen kombiniert einerseits fest, formsteif und nicht zerbrech­lich ausgeführt sind und anderseits leicht herstellbar sind, wobei die Verbindungsprofile verbessert verankert und zudem korrosionsgesichert angeordnet sind.The object of the invention is to provide a preferably lightweight molded block with end connection profiles, which combined with the connection profiles on the one hand are solid, dimensionally stable and not fragile and on the other hand are easy to manufacture, the connection profiles being anchored in an improved manner and also arranged to be corrosion-resistant.

Demgemäß besteht die Erfindung in einem Formstein der vorgenannten Art,der dadurch gekennzeichnet ist, daß mindestens einer der Schenkel (z. B. Verankerungs­schenkel 6, 7) des Verbindungsprofils 2 beidseitig bzw. an seinen beiden Flachseiten vom Material des Formsteins 1 umgeben, fest innerhalb des Endseitenbereichs bzw. -abschnitts in diesen hineinragend eingegossen und darin eingebettet verankert ist.Accordingly, the invention consists in a shaped block of the aforementioned type, which is characterized in that at least one of the legs (z. B. anchoring legs 6, 7) of the connecting profile 2 surrounded on both sides or on its two flat sides by the material of the shaped block 1, firmly within of the end side area or section is cast into this projecting and anchored embedded therein.

Durch die innerhalb des Endseitenbereichs fest eingebettete Verankerung mindestens eines Verankerungs­schenkels des Verbindungsprofils wird eine zusätzliche allseitige Versteifung des Verbindungsprofils erzielt, so daß dieses als solches allein aus vergleichsweise dünnerem und ohne eine solche Einbettung recht instabilen Materials bestehen kann. Außerdem werden entscheidende Vorteile beim Verputz der Trennfugen erzielt. Die innen liegenden Fugen sind praktisch unmittelbar oder mit nur minimalem Überputzen der Fugen tapezierfähig.By firmly anchoring at least one anchoring leg of the connecting profile within the end side area, an additional all-round stiffening of the connecting profile is achieved, so that it as such can consist of comparatively thinner material and without such embedding, quite unstable material. In addition, decisive advantages are achieved when plastering the joints. The internal joints can be papered practically immediately or with only minimal plastering of the joints.

Demgemäß besteht ein wichtiges Merkmal der Erfindung auch darin, daß das Verbindungsprofil im Bereich zwischen der Außenseite des Formsteins und seiner Taupunktzone ange­ordnet ist.Accordingly, an important feature of the invention is that the connecting profile is arranged in the area between the outside of the shaped block and its dew point zone.

Durch die Anordnung des z.B. auch aus Stahl oder Aluminium bestehenden Verbindungsprofils außerhalb der Taupunktzone wird seine Korrosion, insbesondere dann vermieden, wenn der Formstein zudem aus feuchtigkeits­abweisendem Material besteht. Die Verbindungsprofile können auch an den waagerechten Randseiten des Formsteins vorgesehen sein.By arranging the connecting profile, which also consists of steel or aluminum, for example, outside the dew point zone, its corrosion is avoided, in particular if the molded block also consists of moisture-repellent material. The connecting profiles can also be provided on the horizontal edge sides of the shaped block.

Besondere Ausführungsformen der Erfindung ergeben sich beispielsweise aus den Ansprüchen 4 - 13 und 18.Particular embodiments of the invention result, for example, from claims 4-13 and 18.

Als Formsteine umfasst die Erfindung auch Formsteine für Deckenverschalungen und dementsprechende Raumdecken selbst, wobei die Verbindungsprofile zugleich zur An­bringung der Aufhängung dienen.As shaped blocks, the invention also includes shaped blocks for ceiling cladding and corresponding room ceilings themselves, the connecting profiles also serving to attach the suspension.

Ein erfindungsgemäß verwendetes Verbindungsprofil ist dadurch gekennzeichnet, daß es vorzugsweise aus Metall, z.B. Stahl oder Aluminium besteht, einen Stegabschnitt (z.B. Mittelbereich) mit daran längsgerichtet angeordneten Verbindungselementen (z.B. Feder und Nut) aufweist, welche vom Stegabschnitt zum jeweils anderen Formstein hin ragen und einander parallele Führungsflächen besitzen, und daß Verankerungsschenkel vorgesehen sind, welche vom an der Formstein-Stirnebene anzuordnenden Stegabschnitt (Mittelabschnitt) in den Formstein hineinverlaufen und darin fest eingebettet sind, und daß die zwischen beiden Außenseiten gemessene Breite des Verbindungsprofils kleiner ist als der Dickenabstand zwischen der Außenseite und der Taupunktzone im Formstein.A connecting profile used according to the invention is characterized in that it is preferably made of metal, e.g. Steel or aluminum, has a web section (e.g. central area) with longitudinally arranged connecting elements (e.g. tongue and groove), which protrude from the web section to the other molded block and have parallel guide surfaces, and that anchoring legs are provided, which extend from the molded block -Room plane to be arranged web section (middle section) run into the molded block and are firmly embedded therein, and that the width of the connecting profile measured between the two outer sides is smaller than the thickness distance between the outer side and the dew point zone in the molded block.

Weitere Ausführungsformen dazu ergeben sich beispielswei­se aus den Ansprüchen 15 - 17.Further embodiments to this result, for example, from claims 15-17.

Eine aus den erfindungsgemäßen Formsteinen gebildete Wand oder Gebäudedecke wird von der Erfindung voll mitumfasst.A wall or building ceiling formed from the shaped stones according to the invention is fully encompassed by the invention.

Die Erfindung ist nachstehend in verschiedenen Aus­führungsbeispielen näher erläutert.The invention is explained in more detail below in various exemplary embodiments.

Gemäß z.B. Fig.1-6 sind in die senkrecht aneinander anzuordnenden Stirnseiten 3 an beiden Endseiten 4 bzw. 5 eines Formsteins 1 Verbindungsprofile 2 eingeformt, insbesondere eingegossen.According to e.g. Fig.1-6 1 connecting profiles 2 are molded, in particular cast in, in the end faces 3 to be arranged perpendicular to one another on both end sides 4 and 5 of a shaped block.

Der Formstein 1 ist bevorzugt aus einem Leichtbeton bzw. styroporgefülltem Betonmaterial hergestellt und ist daher nicht nur außerordentlich spezifisch leicht, sondern in erhöhtem Maße schalldämpfend und vor allem auch besonders wärmeisolierend ausgebildet. Formsteine dieser Art besitzen bei einer Rohdichte von z.B. 400 Kg/m³, bei Festigkeitswerten von 12 - 15 Kg/cm² sowie einem Wärmekennwert von λr= 0,11 zudem eine verbesserte Branddämmung.The molded block 1 is preferably made of a lightweight concrete or polystyrene-filled concrete material and is therefore not only extremely light, but also has an increased sound-absorbing and, above all, particularly heat-insulating design. Molded stones of this type have a bulk density of e.g. 400 Kg / m³, with strength values of 12 - 15 Kg / cm² and a thermal value of λr = 0.11 also an improved fire insulation.

Bei geschlossem - porigem Styroporkorn - Füllmaterial besitzt der Formstein auch dann eine gute feuchtig­keitsabweisende Eigenschaft bei hoher Festigkeit, wenn die Luftporenbildner allein mit Zement ohne Haftleim vergossen sind. Zur zusätzlichen Festigkeitsverbesse­rung, inbesondere Verbesserung der Biegesteifigkeit - wobei auch eine größere Formsteinlänge ermöglicht wird - können in die Formstein - Mischung Fasern aus alkali­beständigem Material eingearbeitet sein, und zwar vorzugweise aus Kunstoff wie vor allem Polypropylen. Je nach den jeweils gegebenen statischen Erfordernissen kann dafür ein Faseranteil von mindestens etwa 50 - 100g/m³ oder aber auch 200 - 300g/m³ und mehr vorgesehen sein. Dabei ist die Verbesserung der Biegesteifigkeit des Formsteins auch von der Stapelfaserlänge abhängig, welche in der Regel bei etwa 25 - 30mm (z.B. 28mm) oder aber auch bei z.B. 35 - 40 mm und länger liegen kann.In the case of closed, porous Styrofoam grain filling material, the molded block also has good moisture-repellent properties and high strength if the air entraining agents are poured with cement alone without adhesive glue. For additional strength improvement, in particular improvement of the bending stiffness - whereby also a larger shaped stone length is made possible - fibers made of alkali-resistant material can be incorporated into the molded stone mixture, and preferably made of plastic like especially polypropylene. Depending on the given static requirements, a fiber content of at least about 50-100g / m³ or even 200-300g / m³ and more can be provided. The improvement in the bending stiffness of the Shaped stones also depend on the staple fiber length, which can usually be around 25 - 30mm (e.g. 28mm) or also around 35 - 40mm and longer.

Die verwendeten Verbindungsprofile 2 können als ver­gleichsweise schwaches und z.B. für sich nicht verwin­dungsteifes Profil ausgebildet sein. Erst durch die Einformung in die Endseiten 4 und 5 ergeben sie mit der Steifigkeit des Formsteinmaterials ein völlig festes Profilgerüst, das in seiner Festigkeit zum Bau von Wänden in hohem Maße geeignet ist. Insbesondere erstreckt sich das in den Formstein 1 eingeformte Verbindungsprofil 2 über mindestens einen Großteil der Gesamtlänge der jeweiligen Stirnseite 3, praktischerweise auch über ihre Gesamtlänge.The connection profiles 2 used can be comparatively weak and e.g. be designed for a torsionally rigid profile. Only through the molding in the end sides 4 and 5 do they result in a completely solid profile structure with the rigidity of the molded stone material, the strength of which is highly suitable for the construction of walls. In particular, the connection profile 2 molded into the shaped block 1 extends over at least a large part of the total length of the respective end face 3, and practically also over its entire length.

Dafür ist das Verbindungsprofil 2 mit Verankerungsschen­keln 6 und 7 versehen, welche von der Stirnseite 3 her in das Innere des Formsteins 1 hineinragen und darin fest verankert sind. Die Verankerungsschenkel 6/7 können dafür zusätzlich mit Stufen - oder Wellenprofilierungen 8 oder quer in das Formsteinmaterial eingreifenden Halteprofi­lierungen 9, mit denen sie einen Formsteinkern 11 umgrei­fen, oder auch Lochprofilierungen 10 versehen sein.For this purpose, the connecting profile 2 is provided with anchoring legs 6 and 7, which protrude from the end face 3 into the interior of the shaped block 1 and are firmly anchored therein. For this purpose, the anchoring legs 6/7 can additionally be provided with step or corrugated profiles 8 or holding profiles 9 which engage transversely in the shaped stone material and with which they encompass a shaped stone core 11, or else perforated profiles 10.

Ein flacher Mittelbereich 12 eines beispielsweise U - förmigen Verbindungsprofils, wobei der U - Steg den beispielsweise flachen Mittelbereich 12 bildet und die - U - Schenkel die Verankerungsschenkel 6/7, ist mit seiner Außenseite mit der Oberfläche der Stirnseite 3 fluchtend in den Formstein 1 eingeformt, sodaß die Mit­telbereiche 12 zweier mit ihren Stirnseiten 3 aneinan­dergesetzter Formsteine aneinander liegen, wobei dazwischen auch noch eine Dichtung vorgesehen sein kann.A flat middle region 12 of a, for example, U-shaped connecting profile, the U-web forming the, for example, flat middle region 12 and the U-leg forming the anchoring legs 6/7, has the outside with the surface of the end face 3 molded in alignment in the molded block 1, so that the central regions 12 of two molded blocks placed against one another with their end faces 3 lie against one another, a seal also being able to be provided between them.

In diesem Mittelbereich 12 befinden sich ineinandergrei­fende Profilierungen wie z.B. eine Feder 13 und eine Nut 14 oder auch zwei Nuten 14 mit einer dazwischen zusätzlich einfügbaren Feder 15 (Fremdfeder). Dabei kann ein einzelner Feder/Nut - Satz an einer Stirnseitenver­bindung ausreichend sein, aber (z.B. wie in Fig. 1 ange­deutet) auch eine mehrfach formschlüssige Verbindung vorliegen.Interlocking profiles such as e.g. a tongue 13 and a groove 14 or also two grooves 14 with an additionally insertable spring 15 (foreign spring). A single tongue and groove set on an end face connection may be sufficient, but (e.g. as indicated in FIG. 1) there may also be a multiple positive connection.

Gemäß Fig.6 können Loch - Profilverbindungen 19, die auch mit Beton ausgießbar sind oder auch aus über die Anlage­fläche zweier übereinander angeordneter Formsteine rei­chenden, durchgesteckten Profilen (Kreuzprofil, Rohre) bestehen können, zur Stabilisierung der übereinander angeordneten Formsteine 1 miteinander in Kombination zu den Verbindungsprofilen 2 eingesetzt werden. Diese Loch - Profilverbindungen bestehen aus durch den Formstein 1 senkrecht durchgehenden Löchern, in die die Profile gesteckt sind.According to FIG. 6, perforated profile connections 19, which can also be poured out with concrete or can also consist of push-through profiles (cross profile, pipes) reaching over the contact surface of two stacked shaped stones, for stabilizing the stacked shaped stones 1 with one another in combination with the Connection profiles 2 are used. These hole-profile connections consist of holes through the shaped block 1, into which the profiles are inserted.

Als Material für die Verbindungsprofile 2 kann erfin­dungsgemäß durchaus auch Metall (z.B. Stahl) verwendet werden, wenn die Verbindungsprofile 12 mit allen ihren Bestandteilen innerhalb des Formsteins außerhalb der Taupunktzone 16 angeordnet werden, die i.d.R. stark asymmetrisch zur Rauminnenseite 17 hin verlagert liegt. Damit wird eine Feuchtigkeitskorrosion des Verbindungs­ profils 2 vollständig vermieden, obwohl es zur Wand­außenseite 18 hin im Formstein 1 angeordnet ist; dies gilt insbesondere bei für den Formstein 1 verwendetem feuchtigkeitabweisenden Steinmaterial.According to the invention, metal (for example steel) can also be used as the material for the connecting profiles 2 if the connecting profiles 12 with all their components are arranged inside the molded block outside the dew point zone 16, which is generally displaced asymmetrically towards the interior 17 of the room. This will result in moisture corrosion of the connection Profiles 2 completely avoided, although it is arranged towards the outside wall 18 in the molded block 1; this applies in particular to moisture-repellent stone material used for molded stone 1.

Wenn an den Randseiten der jeweiles aneinanderstoßenden Stirnseiten 3 zurückversetzte Innenschultern 19 vorge­sehen sind und diese an der Innenwandseite 17 und der Außenwandseite 18, oder auch nur an der Außenwandseite 18 mit einem elastischen Packungselement ausgelegt oder aus­gespachtelt werden, dann ist die Anbringung von Verputz auch über den Stoßstellen stark vereinfacht und dauerhaft gewährleistet. Die Rauminnenseite 17 ist dann auch sogar sofort tapezierfähig.If recessed inner shoulders 19 are provided on the edge sides of the respective abutting end faces 3 and these are designed or filled with an elastic packing element on the inner wall side 17 and the outer wall side 18, or only on the outer wall side 18, then the plastering is also applied over the Joints greatly simplified and permanently guaranteed. The inside of the room 17 can then even be papered immediately.

In Sonderfällen, kann aber auch der zur Wandaußenseite 18 hin angeordnete Schenkel des Verbindungsprofils 2 mit seiner Außenfläche mit der Stein - Außenseite fluchten bzw. nach außen hin freiliegen, z.B. als Stoßkante für die Formsteinkante.In special cases, however, the leg of the connecting profile 2 which is arranged on the outside of the wall 18 can be flush with the outside of the stone with its outer surface or can be exposed to the outside, e.g. as a joint edge for the shaped stone edge.

Eine derartige Ausführungsform kann gemäß Fig. 11 aber auch zur Verwendung des Formsteins als Deckenelement 24 dienen. Der nach der Raum - Außenseite 18 hin freilie­gende Schenkel 6 des Verbindungsprofils 2 besitzt ein Aufhängeelement 21 z.B. in Form einer Schwalbenschwanz­nut, in welche ein an einer Aufhängung 23 befindliches Tragprofil 22 eingreift. Auch können die Schenkel 6 und 7 unterschiedlich tief in den Formstein 1 eingreifen, um z.B. unterschiedliche Biegemomente auszugleichen. Eben­ so kann z.B. gemäß Fig. 11 die Anordnung der Verbindungs­profile 2 zur Formsteinmitte versetzt vorliegen, wobei auch im Deckenelement 24 die Anordnung vollständig außerhalb der Taupunktzone 16 gewährleistet bleibt.11, such an embodiment can also be used to use the shaped block as a ceiling element 24. The leg 6 of the connecting profile 2 which is exposed towards the outside of the room 18 has a suspension element 21, for example in the form of a dovetail groove, in which a support profile 22 located on a suspension 23 engages. The legs 6 and 7 can also engage at different depths in the shaped block 1, for example in order to compensate for different bending moments. Just For example, according to FIG. 11, the arrangement of the connecting profiles 2 can be offset from the center of the molded block, the arrangement in the ceiling element 24 also remaining completely outside the dew point zone 16.
