Definitions
- thermally insulating brick is from the EP 2 151 531 A2 known, the pressure elements are constructed, for example, cement mortar and the heat-insulating body is preferably made of glass or stone foam, in which case serves as a means for transverse force transmission a structured, optionally applied with chippings surface.
- the pressure elements are constructed, for example, cement mortar and the heat-insulating body is preferably made of glass or stone foam, in which case serves as a means for transverse force transmission a structured, optionally applied with chippings surface.
- Such a brick can undoubtedly convincing in terms of thermal insulation and in terms of pressure transmission
- the technical features suggested in this document are not convincing.
- a non-generic Kragplattenan gleichelement is from the EP 0 338 972 A1 known, in which the two opposing contact surfaces for the components to be thermally insulated on the same plane are opposite.
- Such a cantilevered connection element is provided for connecting balconies as examples of cantilever plates with an adjacent bottom cover plate.
- the known Kragplattenan gleichelement comprises a cuboid insulating body, which is crossed by pairs superposed, the insulating body horizontally passing through pressure bars. To avoid rust attack of these cost reasons, preferably not made of stainless steel pressure rods they are each surrounded with sleeves, between the sleeves and the pressure rods, a curable material, such as a plastic-coated mortar is filled.
- connection element for building connections, in which an insulating body is crossed by obliquely extending at an angle to the vertical between 1 ° and 89 °, in pairs connected to a reinforcing plate reinforcing bars.
- the known connection element thus seems to have exclusively lateral force-transmitting elements, since the stiffening plate is suitable as a pressure element neither in terms of its construction nor with regard to its introduction within this document.
- thermal insulation element for heat flow decoupling between wall part and floor panels.
- the known thermal insulation element may have columnar support elements with an interstices between these support elements aus slaughterdem insulating.
- transverse and tensile force transmission anchoring projections are to serve, which are applied in the form of dowels plan on the outer sides of the proposed thermal insulation element.
- the heat insulation element known in this type may convince with regard to its thermal insulation, and even slight transverse forces may be intercepted, which may arise during the transport of such a known structure, an approach for a convincing solution to the problem of interception of larger lateral forces, as may occur, for example, from planned earth pressure or wind stabilization - here in a possible order of magnitude at least above 10 kN / m - However, it can not be inferred from the text.
- FIG. 1 On the basis of a conventional concrete construction (11) the usual elevation of a concrete wall (15) on a concrete floor slab (13).
- the concrete floor plate (13) and the concrete wall (15) are monolithic, non-positively and uninsulated connected to each other.
- the thermal insulation (5, 7) is provided on the outside both below the concrete floor panel (13) and on the outside of the concrete wall (15).
- the thermal insulation (7), which is arranged under the concrete floor slab (13) must be static-resistant, depending on the load height, pressure-resistant, aging-resistant and resistant to rotting.
- the required compressive strength of the thermal insulation (7) under the floor slab usually has to be> 150 kN / m 2 .
- the materials usually used for this purpose are XPS boards, foam glass blocks or foam glass gravel. These materials are high quality and pressure resistant materials. Due to high compressive strengths, lower thermal insulation values result with a lambda> 40 mW / mK.
- the comparatively high thermal conductivity leads with constant thermal insulation performance to higher layer thicknesses and thus to higher material consumption than comparable solutions with internal insulation. Due to the high consumption of technically complex materials (gray energy), the ecology of the building is also adversely affected. Nevertheless, such a design, for lack of alternatives, for low-energy and passive house concepts is applied.
- the concrete structure (11) according to FIG. 2 is monolithic, non-positive and insufficiently insulated.
- the thermal insulation (5, 9) is on the outer wall (15) lying outside arranged while it is disposed on the concrete floor plate (13) resting.

- FIGS. 3 and 4 is a non-pressure-resistant thermal insulation (9) below and / or above a concrete (cellar) ceiling (29) arranged, as it finds application for unheated basements.
- a concrete structure (11) is also monolithic, non-positive and insufficiently insulated.

Die erforderliche Druckfestigkeit der Wärmedämmung (7) unter der Bodenplatte muss in der Regel > 150 kN/m2 sein. Die dafür üblicherweise eingesetzten Materialien sind XPS-Platten, Schaumglasblöcke oder Schaumglasschotter. Bei diesen Materialien handelt es sich um hochwertige und druckfeste Materialien. Auf Grund hoher Druckfestigkeiten ergeben sich geringere Wärmedämmwerte mit einem Lambda > 40 mW/mK. Die vergleichsweise hohe Wärmeleitfähigkeit führt bei gleichbleibender thermischer Dämmleistung zu höheren Schichtdicken und damit zu höherem Materialverbrauch als vergleichbare Lösungen mit innen liegenden Dämmungen. Durch den hohen Verbrauch von technisch aufwendigen Materialien (graue Energie) wird die Ökologie des Gebäudes zudem negativ beeinflusst. Trotzdem wird eine solche Konstruktion, mangels Alternativen, für Niedrigenergie- und Passivhaus-Konzepte angewandt.The required compressive strength of the thermal insulation (7) under the floor slab usually has to be> 150 kN / m 2 . The materials usually used for this purpose are XPS boards, foam glass blocks or foam glass gravel. These materials are high quality and pressure resistant materials. Due to high compressive strengths, lower thermal insulation values result with a lambda> 40 mW / mK. The comparatively high thermal conductivity leads with constant thermal insulation performance to higher layer thicknesses and thus to higher material consumption than comparable solutions with internal insulation. Due to the high consumption of technically complex materials (gray energy), the ecology of the building is also adversely affected. Nevertheless, such a design, for lack of alternatives, for low-energy and passive house concepts is applied.

Damit soll das diesseits vorgeschlagene Anschlusselement (17) geschichtet beispielsweise zwischen einer Betonplatte und einer Betonwand positioniert sein, wobei es vollkommen unerheblich im Sinne der Erfindung ist, welches der beiden Betonteile aus Betonplatte und Betonwand oberhalb und welches unterhalb des vorgeschlagenen Anschlusselements (17) gelegen ist. Gerade bei den bevorzugten Ausführungsformen von Betonboden- und Betondeckenplatte sowie Betonwand können die einerseits das Druckkraft übertragende Anschlusselement (17) in Richtung des ersten gegossenen Bauteils (13, 29) überragenden und andererseits das Druckkraft übertragende Anschlusselement (17) in Richtung des zweiten gegossenen Bauteils (15) überragenden Mittel zur Querkraftübertragung kraftschlüssig mit den Betonbauteilen (13, 15, 29) verbunden werden, indem diese ein- oder beidseitig an das Druckkraft übertragende Anschlusselement (17) angegossen werden.

Besonders vorteilhaft weist der Isolationskörper (31) ein Steifemodul von größer 80 N/mm2, vorzugsweise größer 100 N/mm2 und ganz besonders bevorzugt größer 150 N/mm2 auf. Dies hat den Vorteil, dass das mindestens eine Druckelement (33) oder die ausgebildete Vielzahl an Druckelementen (33) durch das umgebende Material des Isolationskörpers (31) gestützt ist/sind und keinen oder nur besonders geringen Scherkräften ausgesetzt ist/sind.

Es ist auch vorstellbar und je nach Einbausituation sogar von ganz besonderem Vorteil, wenn bei einer Mehrzahl von den Isolationskörper (31) durchdringenden Druckelementen (33) diese aus unterschiedlichen Materialien bestehen: so ist es beispielsweise vorstellbar und gilt als eine besonders hervorragende Ausführungsform der Erfindung, wenn entlang der Längsmittelachse (A) positionierte Druckelemente (33) mit vergrößerter Querschnittsfläche aus Faserbeton bestehen oder diesen umfassen, während von der Längsmittelachse (A) nach außen gerückte Druckelemente (33) mit verkleinerter Querschnittsfläche aus Stahl bestehen oder diesen umfassen.The pressure element (33) penetrating the insulating body (31) from its first bearing surface (39) to its second bearing surface (41) is advantageously made of steel, stainless steel, fiber plastic, concrete, fiber concrete or another pressure-resistant, ie substantially non-compressible Material produced, on the part of the inventors a special preference for concrete, fiber concrete and fiber plastic, because here also the at least one pressure element (33) a good thermal insulation between the two the insulating body (31) limiting support surface (39, 41) guaranteed. It is also conceivable and depending on the installation situation, even of very particular advantage, if in a plurality of the insulating body (31) penetrating pressure elements (33) consist of different materials: so it is conceivable, for example and is considered a particularly excellent embodiment of the invention, when along the longitudinal central axis (A) positioned pressure elements (33) consist of or comprise expanded fiber reinforced concrete, during the longitudinal central axis (A) outwardly displaced pressure elements (33) with reduced cross-sectional area Consist of steel or include this.

Zweckmässigerweise ist das Druckelement (33) in den Isolationskörper (31) schlupffrei eingesetzt. Dies hat den Vorteil, dass das mindestens eine Druckelement (33) durch den umgebenden Isolationskörper (31) zusätzliche Stabilität erhält.Conveniently, the pressure element (33) in the insulating body (31) is inserted without slip. This has the advantage that the at least one pressure element (33) receives additional stability through the surrounding insulation body (31).
Das mindestens eine Druckelement (33) kann an seinen, den Pressungsflächen angrenzenden Enden gemäß der in der

Eine besondere Präferenz der Erfinderschaft liegt dabei in dem Ausführungsbeispiel (F) gemäß
Erfindungsgemäß weist das mindestens eine Druckelement (33) einerseits zugewandt dem ersten gegossenen Bauteil (13, 29) und/oder andererseits zugewandt dem zweiten gegossenen Bauteil (15) eine bzw. jeweils eine horizontale Pressungsfläche auf, was bedeutet, dass die Pressungsflächen als direkte Kontaktflächen zwischen dem ersten und/oder dem zweiten Bauteil (13, 15, 29) auf der einen Seite und dem mindestens einen Druckelement (33) auf der anderen Seite nicht gewölbt, sondern flach und parallel zu den beiden Auflageflächen (39, 41) hin ausgebildet sind, wobei sie gegebenenfalls eine leichte Struktur, beispielsweise gekörnt und/oder mit Fischgrätmuster, enthalten. Ganz besonders bevorzugt ist es, wenn an mindestens einem stirnflächigen Ende des mindestens einen Druckelements (33) mindestens ein Druckverteilelement (51) als eine solche, wie vorab definierte horizontale Pressungsfläche ausgebildet ist.According to the invention, the at least one pressure element (33) facing the first cast component (13, 29) on the one hand and / or the second cast component (15) on the other hand has one or respectively one horizontal pressure surface, which means that the pressure surfaces act as direct contact surfaces not curved on the other side between the first and / or the second component (13, 15, 29) on the one side and the at least one pressure element (33), but flat and parallel to the two bearing surfaces (39, 41) optionally containing a light structure, for example grained and / or herringbone. It is very particularly preferred if at least one pressure distribution element (51) is formed as such a previously defined horizontal pressure area on at least one end of the at least one pressure element (33).
Im Rahmen einer ganz besonders bevorzugten Ausführungsform überragt die horizontale Pressungsfläche des mindestens einen Druckelements (33) mindestens eine - ganz besonders bevorzugt beide - der beiden Auflageflächen (39, 41) des Isolationskörpers (31) um eine maximale Länge zwischen 0 mm und 10 mm, mehr bevorzugt zwischen 0 mm und 5 mm bzw. noch weiter eingeschränkt zwischen 0 mm und 3 mm, und ganz besonders bevorzugt sind die horizontalen Pressungsflächen und die beiden Auflageflächen (39, 41) des Isolationskörpers (31) plan, das bedeutet, jeweils in einer gemeinsamen Ebene liegend, ausgebildet. Durch Verwirklichung dieses bevorzugten Merkmals wird es ermöglicht, mögliche Schwindprozesse der angegossenen Betonbauteile (13, 15, 29) möglichst wenig zu behindern, da dies sonst zu unerwünschten Spannungen im ausgehärteten Beton führt. Die Ausführung der Pressungsflächen als horizontaler Abschluss des mindestens einen Druckelements (33) dient in erfindungswesentlicher Weise dazu, auf den Druckelementen (33) ruhende Baulasten vertikal nach unten abzuleiten, ohne dass zusätzlich horizontale Kräfte aufgebaut werden, die zu Spannungen im Beton bzw. in oberhalb des hier vorgeschlagenen Anschlusselements (17) gelegenen Baukörpern und/oder im erfindungsgemäßen Anschlusselement (17) selbst führen würden.In a very particularly preferred embodiment, the horizontal pressing surface of the at least one pressure element (33) projects beyond at least one - most preferably both - the two bearing surfaces (39, 41) of the insulating body (31) by a maximum length between 0 mm and 10 mm, more preferably between 0 mm and 5 mm or even more limited between 0 mm and 3 mm, and most preferably, the horizontal pressing surfaces and the two bearing surfaces (39, 41) of the insulating body (31) are flat, that means, each in one common plane lying, trained. By implementing this preferred feature, it is possible to impede possible shrinkage processes of the cast concrete components (13, 15, 29) as little as possible, otherwise this leads to undesirable stresses in the hardened concrete. The execution of the pressing surfaces as a horizontal conclusion of the at least one pressure element (33) serves in essential to the invention, on the pressure elements (33) resting building loads to dissipate vertically downwards, without additionally building up horizontal forces be, which would lead to stresses in the concrete or in above the connection element (17) proposed here building structures and / or in the connection element (17) according to the invention itself.
Sofern an mindestens einem stirnflächigen Ende des mindestens einen Druckelements (33) mindestens ein Druckverteilelement (51) beispielsweise in Form einer Druckverteilplatte als horizontale Pressungsfläche ausgebildet ist, gilt es als ganz besonders bevorzugt, wenn
- bei genau einem ausgebildeten Druckverteilelement (51) die Fläche dieses Druckverteilelements (51)
- bei einer Vielzahl von ausgebildeten Druckverteilelementen (51) die Gesamtfläche dieser Druckverteilelemente (51)
- with exactly one trained pressure distribution element (51), the surface of this pressure distribution element (51)
- in the case of a multiplicity of formed pressure distribution elements (51), the total area of these pressure distribution elements (51)
Neben den im vorherigen Absatz beschriebenen Druckverteilplatten als bevorzugte Ausbildungsvariante der optionalen Druckverteilelemente (51) sind auch die folgenden Beispiele für solche Druckverteilelement (51) vorstellbar und gelten überdies als bevorzugt:
- ■ geradlinige Stäbe, insbesondere aus Metall oder kunststoffummanteltem Metall, parallel verlaufend zu den den Isolationskörper (31) begrenzenden Auflageflächen (39, 41),
- ■ geschwungene oder spiralförmig gebogen Stäbe, insbesondere aus Metall oder kunststoffummanteltem Metall, verlaufend in einer Ebene, parallel zu den den Isolationskörper (31) begrenzenden Auflageflächen (39, 41),
- ■ Gitter, insbesondere aus Metall, kunststoffummanteltem Metall, Faserkunststoffe oder Kunststoffe, verlaufend in einer Ebene, parallel zu den den Isolationskörper (31) begrenzenden Auflageflächen (39, 41).

- Curved or spirally bent rods, in particular of metal or plastic-coated metal, running in a plane parallel to the bearing surfaces (39, 41) delimiting the insulating body (31),
- ■ Grid, in particular of metal, plastic-coated metal, fiber plastics or plastics, extending in a plane parallel to the support body (31) limiting support surfaces (39, 41).

Es gilt dabei als bevorzugt, wenn dieses Überragen um eine Länge in einem Bereich von 2 bis 100 cm, weitergehend eingeschränkt in einem Bereich von 4 bis 70 cm, und noch weitergehend eingeschränkt in einem Bereich von 4 bis 50 cm geschieht. Es kann so in einem besonders überzeugenden Maße eine kraftschlüssige Verbindung der Mittel zur Querkraftübertragung mit der möglichen Armierung inmitten des ersten gegossenen Bauteils (13, 29) bzw. des zweiten gegossenen Bauteils (15) ermöglicht werden.It is considered to be preferred if this protrusion occurs by a length in a range of 2 to 100 cm, further limited in a range of 4 to 70 cm, and even more restricted in a range of 4 to 50 cm. It can be made possible in a particularly convincing measure a non-positive connection of the means for transverse force transmission with the possible reinforcement in the middle of the first molded component (13, 29) and the second molded component (15).
Für die Mittel zur Querkraftübertragung können sowohl stabförmige Elemente (z.B. geradlinig oder gebogen ausgebildete Armierungsstäbe) und plattenförmige Elemente, wie auch diverse weitere Profilkonstruktionen angewendet werden. Bevorzugt umfassen die Mittel zur Querkraftübertragung mindestens ein das Druckkraft übertragende Anschlusselement (17) geradlinig und durchgängig durchlaufendes Querkraft übertragendes Element (35), ganz besonders bevorzugt werden die Mittel zur Querkraftübertragung in erster Linie bzw. ausschließlich von derartigen gebogenen oder geradlinigen, stabförmigen und durchgängigen Querkraft übertragendes Element (35) ausgebildet.

Das Querkraft übertragendes Element (35) kann dabei aus mehreren Einzelstücken bestehen, die vor Einfügung in das Anschlusselement (17) miteinander verklebt, verschweißt oder sonst wie dauerhaft miteinander verbunden worden sind. Besonders bevorzugt im Sinne der vorliegenden Schrift durchläuft das Querkraft übertragendes Element (35) das Anschlusselement (17) einstückig, was bedeutet, dass das Querkraft übertragende Element (35) aus einem einzigen, nicht zusammengesetzten, sondern fortlaufend ununterbrochenen Werkstück besteht.For the means of transverse force transmission, both rod-shaped elements (e.g., rectilinear or curved reinforcing bars) and plate-like elements, as well as various other profile constructions may be used. Preferably, the means for transmitting lateral force comprise at least one pressure element transmitting connecting element (17) straight and continuously passing transverse force transmitting element (35), most preferably the means for transverse force transmission primarily or exclusively of such curved or rectilinear, rod-shaped and continuous transverse force formed transmitting element (35).

The transverse force transmitting element (35) can consist of several individual pieces, which are glued together before insertion into the connecting element (17), welded or otherwise permanently connected to each other. Particularly preferred in the context of the present document, the lateral force transmitting element (35) passes through the connecting element (17) in one piece, which means that the transverse force transmitting element (35) consists of a single, non-composite, but continuously uninterrupted workpiece.
Bevorzugt ist das mindestens eine Querkraft übertragende Element (35) stabförmig ausgebildet und durchläuft das Anschlusselement (17) geradlinig. Im Rahmen einer weitergehenden bevorzugten Ausführungsform ist es vorgesehen, dass die Mittel zur Querkraftübertragung mindestens ein Paar aus zwei stabförmig ausgebildeten Querkraft übertragenden Elementen (35) umfassen.Preferably, the at least one lateral force transmitting element (35) is rod-shaped and passes through the connecting element (17) in a straight line.

This preferred embodiment is unconditionally combinable with all the other embodiments and variants otherwise proposed in this document, which of course should also apply otherwise and in not separately mentioned cases in the sense of the present invention.

Dabei können Verklebung, Verschweißung und Hartverlötung auch nur punkt- oder strichweise erfolgen; ganz besonders bevorzugt geschieht diese Art der kraftschlüssigen Verbindung jedoch, indem das mindestens eine Druckelement (33) mit den Mitteln zur Querkraftübertragung über die volle Kontaktfläche zwischen ihnen verklebt, verschweißt oder hartverlötet wird. Eine weitere bevorzugte Form der kraftschlüssige Verbindung zwischen dem mindestens einen Druckelement (33) mit den Mitteln zur Querkraftübertragung ist die zumindest teilumfangliche Umschließung entweder

Particularly preferably, the lateral force transmitting element (35) of the at least one pressure element (33) at least quarter, even better semi-circumferentially enclosed, which means in the context of the present specification that at least half of the circumference of the lateral force transmitting element (35) at least 25% of the length of the pressure element (33), dimensioned between the two bearing surfaces (39, 41) of the insulating body (31), immediately adjacent to and preferably non-positively connected to and / or sheathed by the pressure element (33). Quite particularly preferably, the lateral force-transmitting element (35) of the at least one pressure element (33) fully enclosed, which means in the context of the present document that the lateral force transmitting element (35) then over the full length of the pressure element (33) within this Pressure element (33) is formed and with the pressure element (33) so very particularly non-positively and materially connected.
Bei einer bevorzugten Vielzahl an Querkraft übertragenden Elementen (35) innerhalb des vorgeschlagenen Anschlusselements (17) ist es ganz besonders bevorzugt, wenn die Querkraft übertragenden Elemente (35) zumindest größtenteils jeweils paarweise mit mindestens einem Druckelement (33) kraftschlüssig verbunden sind. Dabei ist es eine mögliche Ausführungsform, wenn jeweils ein Paar aus zwei, bevorzugt stabförmig ausgebildeten Querkraft übertragenden Elementen (35) von einem Druckelement (33), zumindest teilumfanglich, ganz besonders bevorzugt sogar vollständig umschlossen ist.In a preferred plurality of transverse force transmitting elements (35) within the proposed connection element (17), it is particularly preferred if the lateral force transmitting elements (35) at least for the most part in pairs with at least one pressure element (33) are non-positively connected. It is a possible embodiment, if in each case a pair of two, preferably rod-shaped transverse force transmitting elements (35) of a pressure element (33), at least partially, even more preferably even completely enclosed.
Im Rahmen der Ausführungsformen mit paarweise ausgebildeten Querkraft übertragenden Elementen (35) gilt es weiterhin als bevorzugt, wenn sich die ein Paar bildenden Querkraft übertragenden Elemente (35) mittig innerhalb des mindestens einen Druckelements (33) kreuzen. Dabei ist es insbesondere vorstellbar, dass bei einer Mehrzahl von den Isolationskörper (31) durchdringenden Druckelementen (33) diese Druckelemente (33)
- teilweise von einem Paar aus mindestens zwei, bevorzugt aus genau zwei stabförmig ausgebildeten Querkraft übertragenden Elementen (35) durchzogen sind, die zumindest bereichsweise abgewinkelt und sich innerhalb der jeweiligen Druckelemente (33) kreuzend ausgebildet sind,

Genauso gilt es als bevorzugt, wenn die sich kreuzenden Querkraft übertragenden Elemente (35) durch jeweils kraftschlüssige Verbindung mit mindestens einem gemeinsamen Druckelement (33) indirekt kraftschlüssig miteinander verbunden sind. Auch vorstellbar ist es und gilt genauso als bevorzugt, wenn die beiden Querkraft übertragenden Elemente (35) im Kreuzungspunkt ausschließlich über das Material des, die beiden Querkraft übertragenden Elemente (35) zumindest teilumfanglich umschließenden Druckelements (33) fixiert sind. In allen vorstehend dargelegten Fällen bestehen die Querkraft übertragenden Elemente (35) jeweils und ohne Beschränkung auf mögliche Ausführungsformen bevorzugt aus einem Material, ausgesucht aus der Liste, umfassend: Stahl, Baustahl, Edelstahl, Faserkunststoff (GFK, CFK), wobei Baustahl und Edelstahl als ganz bevorzugt gelten.In the rod-shaped crossed transverse force transmitting elements (35), it is preferred that these two lateral force transmitting elements (35) are either directly non-positively connected at the intersection, for which a bond as well as a weld offer. In the same way, it is considered preferable if the elements (35) which transmit transverse forces are connected to each other indirectly by force-locking connection with at least one common pressure element (33). It is also conceivable and is just as preferred when the two transverse force transmitting elements (35) are fixed in the crossing point exclusively on the material of the, the two lateral force transmitting elements (35) at least partially enclosing pressure element (33). In all the cases set forth above, the transverse force transmitting elements (35) each consist, without limitation, of possible embodiments, of a material selected from the list comprising: steel, structural steel, stainless steel, fiber plastic (GRP, CFRP), using mild steel and stainless steel very preferably apply.
