  • □ einen durch zwei sich gegenüberliegenden Auflageflächen begrenzten Isolationskörper zur thermischen Trennung des ersten gegossenen Bauteils von dem zweiten gegossenen Bauteil ,
    • wobei die erste den Isolationskörper begrenzende Auflagefläche dem ersten gegossenen Bauteil zugewandt ist,
      und
    • wobei die zweite den Isolationskörper begrenzende Auflagefläche dem zweiten gegossenen Bauteil zugewandt ist,

The present invention relates to a pressure force transmitting connection element, suitable for compressive force transmitting connection of a first molded component with a second molded component. Such a connection element comprises generically:
  • □ an insulating body delimited by two opposing bearing surfaces for thermal separation of the first molded component from the second molded component,
    • wherein the first support surface delimiting the insulating body faces the first molded component,
      and
    • wherein the second support surface bounding the insulating body faces the second molded component,
  • □ at least one pressure element which penetrates the insulating body from its first bearing surface to its second bearing surface,
  • □ means for transverse force transmission,

Ein die gattungsgemäßen Merkmale offenbarender wärmedämmender Mauerstein ist aus der EP 2 151 531 A2 bekannt, dessen Druckelemente beispielsweise aus Zementmörtel aufgebaut sind und dessen Wärmedämmkörper bevorzugt aus Glas- oder Steinschaum besteht, wobei hier als Mittel zur Querkraftübertragung eine strukturierte, gegebenenfalls mit Splitt beaufschlagte Oberfläche dient. Ein solcher Mauerstein kann zweifellos hinsichtlich der Wärmedämmung und hinsichtlich der Druckkraftübertragung überzeugend sein, mit Blick auf die Querkraftübertragung vermögen jedoch die in dieser Schrift angeregten technischen Merkmale nicht zu überzeugen.A generic features revealing 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. Such a brick can undoubtedly be convincing in terms of thermal insulation and in terms of compressive force transmission, but in view of the transverse force transmission assets can not convince excited in this document technical features.

Ein ebenfalls gattungsgemäßes Kragplattenanschlusselement ist aus der EP 0 338 972 A1 bekannt, mit dessen Hilfe insbesondere Balkone als Beispiele für Kragplatten an eine benachbarte Bodendeckplatte angesetzt werden können. Das bekannte Kragplattenanschlusselement umfasst einen quaderförmigen Isolationskörper, der von paarweise übereinander liegenden, den Isolationskörper horizontal durchlaufenden Druckstäben durchzogen ist. Zur Vermeidung eines Rostbefalls dieser aus Kostengründen bevorzugt nicht aus rostfreiem Stahl hergestellten Druckstäbe sind diese jeweils mit Hülsen umgeben, wobei zwischen den Hülsen und den Druckstäben ein aushärtbares Material, beispielsweise ein kunststoffvergüteter Mörtel, eingefüllt ist. In einer möglichen Ausgestaltung des vorgeschlagenen Kragplattenanschlusselements weist dieses auch Querkraft übertragende Elemente auf, die jedoch den Isolationskörper räumlich getrennt von den Druckstäben durchziehen.A likewise generic Kragplattenanschlusselement is from the EP 0 338 972 A1 known, with the help of particular balconies as examples of cantilever plates can be attached to an adjacent ground cover plate. The known Kragplattenanschlusselement 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, filled. In a possible embodiment of the proposed Kragplattenanschlusselements this also has transverse force transmitting elements, however, pull through the insulation body spatially separated from the pressure rods.

Gegenstand der nicht gattungsgemäßen WO 2010 / 046 841 A1 ist ein Anschlusselement für Gebäudeverbindungen, bei dem ein Isolierkörper durch schräg in einem Winkel zur Vertikalen zwischen 1 ° und 89° verlaufende, paarweise mit einer Versteifungsplatte verbundene Bewehrungsstäbe durchzogen ist. Das bekannte Anschlusselement scheint somit ausschließlich über Querkraft übertragende Elemente zu verfügen, da die Versteifungsplatte als Druckelement weder hinsichtlich seiner Konstruktion noch hinsichtlich seiner Einführung innerhalb dieser Schrift geeignet ist. Der Schrift sind im gleichen Maße auch keinerlei Anregungen für die Ausgestaltung jedweder Druckverteilelemente zu entnehmen.Subject of the generic WO 2010/046 841 A1 is a 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. The Scriptures are to be taken to the same extent no suggestions for the design of any Druckverteilelemente.

Aus der DE 94 13 502 U1 ist ebenfalls ein Bauelement für die Wärmedämmung in einem Mauerwerk bekannt. Während als Druckelemente vertikale Tragsäulen aus Zementmörtel offenbart werden, die mittels Stege miteinander verbunden sind, soll das Material für den Wärmedämmkörper aus Polystyrol-Hartschaum bestehen. Hinsichtlich möglicher Mittel zur Querkraftübertragung finden sich in der Schrift jedoch keinerlei Hinweise.From the DE 94 13 502 U1 is also known a component for thermal insulation in masonry. While vertical support columns made of cement mortar are disclosed as printing elements, which are interconnected by means of webs, the material for the heat insulation body made of polystyrene foam. With regard to possible means for transverse force transmission, however, there are no indications in the document.

Solche Hinweise finden sich hingegen in der EP 1 154 086 A2 , die ein Wärmedämmelement zur Wärmeflussentkopplung zwischen Wandteil und Bodenplatten vorschlägt. Das bekannte Wärmedämmelement kann säulenförmige Tragelemente mit einem die Zwischenräume zwischen diesen Tragelementen ausfüllendem Isolierelement aufweisen. Als Mittel zur Quer- und Zugkraftübertragung sollen Verankerungsvorsprünge dienen, die in der Form von Dübeln plan auf die Außenseiten des vorgeschlagenen Wärmedämmelements aufgebracht sind. Das in dieser Art bekannte Wärmedämmelement mag hinsichtlich seiner Wärmedämmung überzeugen, auch können vielleicht leichte Querkräfte abgefangen werden, die während des Transports eines derart bekannten Baukörpers entstehen können, ein Ansatz für eine überzeugende Lösung auf das Problem des Abfangens größerer Querkräfte, wie sie beispielsweise aus planmäßigem Erddruck oder Windstabilisierung - dabei in einer möglichen Größenordnung mindestens oberhalb von 10 kN/m - auftreten können, kann der Schrift jedoch keineswegs entnommen werden.Such hints can be found in the EP 1 154 086 A2 , which proposes a 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 ausfüllendem insulating. As means for the 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 thermal insulation element known in this type may be convincing in terms of its thermal insulation, and perhaps even slight transverse forces that 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, such as from planned Earth pressure or wind stabilization - while in a possible order of magnitude at least above 10 kN / m - may occur, but the font can not be removed.

Schließlich ist aus der EP 2 241 690 A2 ein Anschlusselement für die Fundamentierung von Betonbauteilen bekannt, bei dem in einen Isolationskörper stahlbewehrte Betonsäulen und ein von diesen Säulen getragener Betonquerträger zum dort zu verankernden Anschluss der Geschossdecken eingelassen sind. In einer möglichen Ausführungsform ragen aus den Betonsäulen nach unten Querkraft übertragende Stahldorne heraus.Finally, out of the EP 2 241 690 A2 a connecting element for the foundation of concrete components known in which steel reinforced concrete columns and a concrete cross member carried by these columns are embedded in the anchoring there to be anchored connection of the floors in an insulating body. In one possible embodiment, transverse force-transmitting steel mandrels protrude downwards from the concrete columns.

Entsprechend bekannter Konstruktionen zur Wärmedämmung zeigt die Figur 1 an Hand einer üblichen Betonkonstruktion (11) die übliche Aufständerung einer Betonwand (15) auf einer Betonbodenplatte (13). Die Betonbodenplatte (13) und die Betonwand (15) sind monolithisch, kraftschlüssig und ungedämmt miteinander verbunden. Es ist erkennbar, dass die Wärmedämmung (5, 7) außen liegend sowohl unterhalb der Betonbodenplatte (13) als auch außen an der Betonwand (15) vorgesehen ist. Die Wärmedämmung (7), welche unter der Betonbodenplatte (13) angeordnet ist, muss aus statischen Gründen, abhängig von der Belastungshöhe, druckfest, alterungsbeständig und verrottungsresistent sein.According to known structures for thermal insulation shows the 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. It can be seen that 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.

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.

Die Betonkonstruktion (11) gemäß Figur 2 ist monolithisch, kraftschlüssig und nur unzureichend gedämmt. Die Wärmedämmung (5, 9) ist an der Außenwand (15) außen liegend angeordnet, während sie bei der Betonbodenplatte (13) aufliegend angeordnet ist. Die Nutzung der innenliegenden Dämmung (9) bietet enorme Kostenersparnisse, sowie eine Reduzierung der benötigten grauen Energie, jedoch ist es offensichtlich nachteilig an dieser Ausführung, dass eine bestehende Kältebrücke zwischen der Betonbodenplatte (13) und der Betonwand (15) vorhanden ist.The concrete structure (11) according to FIG. 2 is monolithic, non-positive and insufficiently insulated. The thermal insulation (5, 9) is arranged on the outer wall (15) lying outside, while it is arranged resting on the concrete floor plate (13). The use of the internal insulation (9) offers enormous cost savings, as well as a reduction in the required gray energy, but it is obviously disadvantageous in this embodiment that an existing cold bridge between the concrete floor plate (13) and the concrete wall (15) is present.

In den Figuren 3 und 4 ist eine nicht druckfeste Wärmedämmung (9) unterhalb und/oder oberhalb einer Beton(keller)decke (29) angeordnet, wie es beispielsweise Anwendung findet für nicht beheizte Kellerräume. Eine solche Betonkonstruktion (11) ist ebenfalls monolithisch, kraftschlüssig und nur unzureichend gedämmt. Auch bei dieser Lösung besteht eine Kältebrücke zwischen der Betonwand (15) und der Beton(keller)decke (29). Solche Systeme sind nicht tauglich für Niedrigenergie- bzw. Passivhäuser auf Grund des lokalen Energieverlustes sowie der Gefahr der Schimmelpilzbildung (konstruktive Kältebrücke).In the 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. Such a concrete structure (11) is also monolithic, non-positive and insufficiently insulated. Also in this solution, there is a cold bridge between the concrete wall (15) and the concrete (basement) ceiling (29). Such systems are not suitable for low-energy or passive houses due to the local energy loss and the risk of mold fungus formation (constructive cold bridge).

Ziel ist es weiterhin, eine Lösung vorzuschlagen, mit deren Hilfe Betonkonstruktionen mit geringem finanziellem und technischem Aufwand die neuen und zukünftigen Energiestandards erfüllen können. Elementares Element innerhalb der Aufgabe für die hier vorliegende Erfindung ist es vor diesem Hintergrund, eine möglichst große Freiheit hinsichtlich der Auswahl des Materials für den Isolationskörper (31) zu erhalten, ohne übermäßig hinsichtlich der Höhe der Frischbetonierung oberhalb des erfindungsgemäßen Anschlusselements (17) eingeschränkt zu sein. Ein weiteres Ziel der vorliegenden Erfindung ist es, der Öffentlichkeit eine Betonkonstruktion mit einem optimalen Kraftfluss bei gleichzeitig optimierter Wärmedämmung vorzuschlagen.Based on the previously acknowledged printed and by means of FIGS. 1 to 4 It is the object of the present invention, the public a connecting element for two interconnected, cast components, which are preferably on the one hand concrete floor or ceiling and the other concrete wall to propose, which largely eliminates the usually resulting, constructive cold bridges in concrete structures and which is as it is capable of large pressure forces and to absorb large lateral forces. The goal is still to propose a solution that allows concrete structures to meet the new and future energy standards with little financial and technical effort. Against this background, it is an elementary element within the object of the present invention to obtain the greatest possible freedom with regard to the selection of the material for the insulating body (31) without being restricted in terms of the amount of fresh concrete above the connecting element (17) according to the invention be.

Das zweite gegossene Bauteil (15) ist eine Betonwand. Durch diese Ausführungsformen können die das mindestens eine Druckkraft übertragende Anschlusselement (17) durchgängig durchlaufenden Querkraft übertragenden Elemente (35) kraftschlüssig mit den Betonbauteilen (13, 15, 29) verbunden werden, indem diese ein- oder beidseitig an das Druckkraft übertragende Anschlusselement (17) angegossen werden. Gerade bei dem Anguss insbesondere von hoch aufragenden Betonwänden (15) auf dem erfindungsgemäßen Anschlusselement (17) stellt die Ausbildung des mindestens einen Druckverteilelements (51) an mindestens einem stirnflächigen Ende des mindestens einen Druckelements (33) entscheidende Vorteile dar. In einem besonderen Maße stellt es eine bevorzugte Ausführung dar, wenn mindestens ein Druckverteilelement (51) sowohl an dem einen wie auch an dem anderen der beiden stirnflächigen Enden des mindestens einen Druckelements (33) ausgebildet ist. Im eingebauten Zustand ist dann das erfindungsgemäße Anschlusselement (17) zwischen einer Betonbodenplatte (13) und einer Betonwand (15) oder zwischen einer Betondeckenplatte (29) und einer Betonwand (15) angeordnet, wodurch eine effektive thermische Trennung zwischen den beiden Betonteilen gewährleistet ist. Ohne darauf beschränkt zu sein, ist es dabei gemäß sämtlicher hier vorgeschlagener Varianten und Ausführungsformen bevorzugt, wenn im eingebauten Zustand die beiden gegossenen Bauteile (13, 15, 29) mit dem dazwischen positionierten erfindungsgemäßen Anschlusselement (17) geschichtet übereinander gelegen sind.Without being limited to these embodiments, the first molded component (13, 29) is preferably an element selected from the list comprising concrete floor slab and concrete slab. The second molded component (15) is a concrete wall. By means of these embodiments, the connecting element (17) transmitting the at least one compressive force can be connected in a force-locking manner to the concrete components (13, 15, 29) by continuous transverse force-transmitting elements (35), by these connection elements (17) transmitting on one or both sides to the pressure force. to be poured on. Especially in the case of the sprue, in particular of towering concrete walls (15) on the connection element (17) according to the invention, the formation of the at least one pressure distribution element (51) on at least one end face of the at least one pressure element (33) is a decisive advantage it is a preferred embodiment, if at least one pressure distribution element (51) is formed both on one and on the other of the two end faces of the at least one pressure element (33). When installed, the connection element (17) according to the invention between a concrete floor plate (13) and a concrete wall (15) or between a concrete ceiling slab (29) and a concrete wall (15) is arranged, whereby an effective thermal separation between the two concrete parts is guaranteed. Without being limited thereto, it is preferred according to all variants and embodiments proposed here, when in the installed state, the two molded components (13, 15, 29) are layered one above the other with the connection element (17) according to the invention positioned therebetween.

Das mindestens eine Druckverteilelement (51) an dem mindestens einem stirnflächigen Ende des mindestens einen Druckelements (33) bzw. gleichsam bevorzugt das mindestens ein Druckverteilelement (51) sowohl an dem einen wie auch an dem anderen der beiden stirnflächigen Enden des mindestens einen Druckelements (33) ist bevorzugt wahlweise

  • außenflächig bündig mit den, den Isolationskörper (31) begrenzenden Auflageflächen (39,41) oder
  • überstehend bezogen auf die, den Isolationskörper (31) begrenzenden Auflageflächen (39,41)
ausgestaltet.The at least one pressure distribution element (51) at the at least one end face of the at least one pressure element (33) or at least one pressure distribution element (51) both at one and at the other of the two end faces of the at least one pressure element (33 ) is preferably optional

  • □ genau ein Druckverteilelement (51) ausgebildet ist, gilt es als bevorzugt, wenn die Fläche dieses Druckverteilelements (51)

Als Materialien für den Isolationskörper (31) bieten sich, ohne abschließend darauf beschränkt zu sein,

Auch diese Anforderungen erfüllt das diesseits ganz besonders bevorzugte Schaumglas in hervorragendem Maße.Due to the exposed position of the connecting element (17) of the insulating body (31) is machined out of a material which is suitably waterproof and particularly preferably water vapor-tight, preferably resistant to aging and resistant to pest infestation and rotting. These requirements also meets the most preferred foam glass on this side to an outstanding extent.

Erfindungsgemäß ist der Isolationskörper (31) mindestens von genau einem Druckelement (33) durchdrungen. Zur notwendigen Übernahme der vorgesehenen Druck- und Scherkräfte weist in einem solchen Fall dieses Druckelement (33) im Fall seiner Singularität eine größere Ausdehnung in Längs- und Querachse auf als es der Fall ist, wenn mehrere voneinander beabstandet ausgebildete Druckelemente (33) den Isolationskörper (31) durchdringen. Dabei gilt es als bevorzugt, wenn

  • bei genau einem den Isolationskörper (31) durchdringenden Druckelement (33) die Querschnittsfläche des Druckelements (33)
  • bei einer Mehrzahl von den Isolationskörper (31) durchdringenden Druckelementen (33) die Summe der Querschnittsflächen der Druckelemente (33)
einen prozentualen Anteil von 0,3% bis 62,5%, ganz besonders bevorzugt- insbesondere bei Beton als Material für die den Isolationskörper (31) durchdringenden Druckelemente (33) - von 4% bis 25% und noch besser von 4% bis 15%, bezogen wahlweise auf die erste den Isolationskörper (31) begrenzende Auflagefläche (39) oder auf die zweite den Isolationskörper (31) begrenzende Auflagefläche (41), ausmacht. Bei einer Wahl von Stahl bzw. von Materialien ähnlicher Festigkeit als Material für die den Isolationskörper (31) durchdringenden Druckelemente (33) gilt ein prozentualer Anteil von 0,3% bis 4,5%, bezogen wahlweise auf die erste den Isolationskörper (31) begrenzende Auflagefläche (39) oder auf die zweite den Isolationskörper (31) begrenzende Auflagefläche (41), als ganz besonders bevorzugt. Bei dem einen Druckelement (33) oder bei den mehreren Druckelementen (33) mit über dessen/deren Länge variierender Querschnittsfläche gilt als jeweilige Querschnittsfläche das diesbezügliche Minimum als zu berücksichtigende Größe, bestimmt an der Position des jeweiligen Druckelements (33), wo dessen Querschnittsfläche den geringst möglichen Wert annimmt.According to the invention, the insulation body (31) is penetrated by at least one pressure element (33). In the case of its singularity, this pressure element (33), in the case of its singularity, has a greater expansion in the longitudinal and transverse axes than is the case if a plurality of spaced-apart pressure elements (33) guide the insulating body (33). 31). It is considered preferable if
  • in the case of exactly one pressure element (33) penetrating the insulation body (31), the cross-sectional area of the pressure element (33)
  • in the case of a plurality of pressure elements (33) penetrating the insulation bodies (31), the sum of the cross-sectional areas of the pressure elements (33)
a percentage of 0.3% to 62.5%, most preferably - in concrete as material for the insulating body (31) penetrating pressure elements (33) - from 4% to 25% and more preferably from 4% to 15 %, relative to the first support surface (39) delimiting the insulation body (31) or to the second support surface (41) delimiting the insulation body (31). In a choice of steel or materials of similar strength as a material for the insulating body (31) penetrating pressure elements (33) applies a percentage of 0.3% to 4.5%, based selectively on the first the insulating body (31) limiting support surface (39) or on the second the insulating body (31) limiting support surface (41), as very particularly preferred. In the one pressure element (33) or in the plurality of pressure elements (33) with over its / their length varying cross-sectional area applies as the respective cross-sectional area, the relevant minimum as the size to be considered, determined at the position of the respective pressure element (33), where its cross-sectional area the lowest possible value.

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.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 reinforced concrete or another pressure-resistant, ie. The inventors have made a special preference for concrete, fiber-reinforced concrete and fiber-reinforced plastics, because here too the at least one pressure element (33) ensures good thermal insulation between the two bearing surfaces (39, 41) delimiting the insulating body (31) ) guaranteed. 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 Enden gemäß der in der Figur 11 , dort a bis e, gezeigten Ausführungsbeispielen grundsätzlich unterschiedliche Grundflächen (34) wie quadratisch (a), rechteckig (b), Kreuz-Profil (c), rund (d), oval oder elliptisch (e), etc. aufweisen.The at least one pressure element (33) can at its ends according to the in FIG. 11 , A to e, embodiments shown therein basically different bases (34) such as square (a), rectangular (b), cross-profile (c), round (d), oval or elliptical (e), etc. have.

Im Längsschnitt können die Druckelemente (33) gemäß Figur 12 ebenfalls unterschiedliche Körperformen (45) aufweisen. Der Körper (45) der Druckelemente (33) zwischen seinen Grundflächen (34) an den beiden Enden kann zylindrisch (A), relativ zu einer (C, E) oder beiden Grundflächen (B,D,F,G) verjüngt, nach innen (F) oder nach außen (I) gewölbt sein.In longitudinal section, the pressure elements (33) according to FIG. 12 also have different body shapes (45). The body (45) of the pressure elements (33) between its base surfaces (34) at both ends may be tapered cylindrically (A) relative to one (C, E) or both bases (B, D, F, G) (F) or curved outwards (I).

Eine besondere Präferenz der Erfinderschaft liegt dabei in dem Ausführungsbeispiel (F) gemäß Figur 12, wonach der Querschnitt des mindestens einen Druckelements (33) zur Mitte hin verjüngt ist.A particular preference of the invention lies in the embodiment (F) according to FIG. 12 according to which the cross section of the at least one pressure element (33) tapers towards the middle.

Bevorzugt ist das mindestens eine Druckelement (33) oder sind bei eine Vielzahl an Druckelementen (33) mindestens eine Mehrheit dieser Druckelemente (33) auf der Längsmittelachse (A) des Anschlusselements (17) (im Fachjargon auch als Systemachse bezeichnet), vgl. Figuren 8 und 9 , oder in Abstand zu dieser angeordnet. Im letzteren Fall sind die Druckelemente (33) vorzugsweise so zueinander angeordnet, dass die Kraftresultierende der übertragbaren Druckkraft wiederum ungefähr auf der Längsmittelachse (A) liegt (symmetrische Anordnung). Bei unsymmetrischer Anordnung der Druckelemente (33) außerhalb der Längsmittelachse des Anschlusselements (17), beispielsweise aus Gründen der Optimierung des Kraftflusses, erfolgt die Anordnung ganz besonders bevorzugt so, dass die Druckkraftresultierende maximal 1/3 der Querschnitts-Breite des Anschlusselements (17) außermittig sitzt.Preferably, the at least one pressure element (33) or are at a plurality of pressure elements (33) at least a majority of these pressure elements (33) on the longitudinal central axis (A) of the connection element (17) (also referred to in the jargon as the system axis), see. FIGS. 8 and 9 , or spaced apart from this. In the latter case, the pressure elements (33) are preferably arranged relative to one another such that the force-resultant of the transferable compressive force again lies approximately on the longitudinal central axis (A) (symmetrical arrangement). In an asymmetrical arrangement of the pressure elements (33) outside the longitudinal center axis of the connecting element (17), for example, for reasons of optimizing the power flow, the arrangement is very particularly preferably so that the pressure force resulting maximum 1/3 of the cross-sectional width of the connection element (17) off-center sitting.

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.

Combinations of the aforementioned types of connection are possible and are considered to be preferred in the context of the present invention.

Das Querkraft übertragende Element (35) kann gemäß dieses letzten Vorschlags im vorherigen Absatz von dem mindestens einen Druckelement (33) zumindest teilumfanglich umschlossen werden, was im Sinne der vorliegenden Schrift bedeutet, dass zumindest ein Achtel des Umfangs von dem Querkraft übertragenden Element (35) über mindestens 25 % der Länge des Druckelements (33), bemessen zwischen den beiden Auflageflächen (39, 41) des Isolationskörpers (31), direkt benachbart zu und kraftschlüssig verbunden mit und/oder ummantelt von dem Druckelement (33) ist. Besonders bevorzugt ist das Querkraft übertragende Element (35) von dem mindestens einen Druckelement (33) zumindest viertel-, noch besser halbumfanglich umschlossen, was im Sinne der vorliegenden Schrift bedeutet, dass zumindest die Hälfte des Umfangs von dem Querkraft übertragenden Element (35) über mindestens 25 % der Länge des Druckelements (33), bemessen zwischen den beiden Auflageflächen (39, 41) des Isolationskörpers (31), unmittelbar benachbart zu und kraftschlüssig verbunden mit und/oder ummantelt von dem Druckelement (33) ist. Ganz besonders bevorzugt ist das Querkraft übertragendes Element (35) von dem mindestens einen Druckelement (33) vollumfanglich umschlossen, was im Sinne der vorliegenden Schrift bedeutet, dass das Querkraft übertragende Element (35) dann über die volle Länge des Druckelements (33) innerhalb dieses Druckelements (33) ausgebildet ist und mit dem Druckelement (33) so kraft- und stoffschlüssig verbunden ist. Für das Querkraft übertragende Element (35) können sowohl stabförmige Elemente (z.B. geradlinig oder gebogen ausgebildete Armierungsstäbe) und plattenförmige Elemente, wie auch diverse weitere Profilkonstruktionen angewendet werden.The lateral force transmitting element (35) can be at least partially enclosed by the at least one pressure element (33) according to this last proposal in the previous paragraph, which means for the purposes of the present specification that at least one-eighth of the circumference of the lateral force transmitting element (35) over at least 25% of the length of the pressure element (33), dimensioned between the two bearing surfaces (39, 41) of the insulating body (31), directly adjacent to and frictionally connected to and / or sheathed by the pressure element (33). 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 frictionally 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) is positively and materially connected. For the lateral force transmitting element (35), both rod-shaped elements (e.g., rectilinear or bent reinforcing bars) and plate-shaped elements, as well as various other profile constructions may be used.

Bevorzugt ist das mindestens eine Querkraft übertragende Element (35) stabförmig ausgebildet und durchläuft das Anschlusselement (17) geradlinig. Es ist ferner als bevorzugte Ausführung vorgesehen, dass das Querkraft übertragende Element (35) sowohl einerseits die dem ersten gegossenen Bauteil (13, 29) zugewandte erste Auflagefläche (39) wie auch andererseits die dem zweiten gegossenen Bauteil (15) zugewandte zweite Auflagefläche (41) jeweils überragt, dabei besonders bevorzugt 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. Es kann so in einem besonders überzeugenden Maße eine kraftschlüssige Verbindung der Querkraft übertragenden Elemente (35) mit der möglichen Armierung inmitten des ersten gegossenen Bauteils (13, 29) bzw. des zweiten gegossenen Bauteils (15) ermöglicht werden.Preferably, the at least one lateral force transmitting element (35) is rod-shaped and passes through the connecting element (17) in a straight line. It is further provided as a preferred embodiment that the lateral force transmitting element (35) both on the one hand the first cast component (13, 29) facing the first bearing surface (39) and on the other hand, the second cast component (15) facing the second bearing surface (41 ), in each case more preferably by a length in a range of 2 to 100 cm, further limited in a range of 4 to 70 cm, and even further 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 transverse force transmitting elements (35) with the possible reinforcement in the middle of the first molded component (13, 29) and the second molded component (15).

Im Rahmen einer weiteren bevorzugten Ausführungsform ist es vorgesehen, dass die Mittel zur Querkraftübertragung mindestens ein Paar aus zwei stabförmig ausgebildeten Querkraft übertragenden Elementen (35) umfassen, die jeweils mit dem mindestens einen Druckelement (33) kraftschlüssig verbunden sind. Bei einer Vielzahl an Druckelementen (33) und einer 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 the context of a further preferred embodiment, it is provided that the means for transmitting transverse force comprise at least one pair of elements (35) which transmit two rod-shaped transverse force and which are in each case positively connected to the at least one pressure element (33). With a plurality of pressure elements (33) and a 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 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.

Sowohl im Rahmen der vorgenannten Ausführungsform wie auch generell gilt es als bevorzugt, wenn die das mindestens eine Paar bildenden Querkraft übertragenden Elemente (35), bzw. generell wenn die Querkraft übertragenden Elemente (35), außerhalb des Isolationskörpers (31) mindestens bereichsweise abgewinkelt sind, wobei die abgewinkelten Bereiche auch als Fortsätze (60) bezeichnet werden. Eine solche Abwinkelung der Fortsätze (60) weist insbesondere den Vorteil auf, dass die erfindungsgemäß vorgesehenen Mittel zur Querkraftübertragung auch eine Zugkraftübertragung gewährleisten, weshalb eine solche Konstruktion eine besonders stabile Baukonstruktion, insbesondere Betonbaukonstruktionen (11) ermöglicht, mit denen Verbindungen des ersten gegossenen Bauteils (13, 29) mit dem zweiten gegossenen Bauteil (15) ermöglicht werden, bei denen die Querkraft auch in diametral gegenüberliegenden Richtungen abtragbar sind.Both in the context of the aforementioned embodiment as well as in general, it is considered preferable if the elements (35) transmitting the at least one pair of lateral forces, or generally when the transverse force transmitting elements (35), at least partially angled outside the insulation body (31) , wherein the angled regions are also referred to as extensions (60). Such an angling of the projections (60) has in particular the advantage that the means according to the invention for transverse force transmission also ensure a tensile force transmission, which is why such a construction enables a particularly stable building construction, in particular concrete structures (11) with which connections of the first cast component (FIG. 13, 29) are made possible with the second molded component (15), in which the transverse force can be ablated in diametrically opposite directions.

Im Rahmen der Ausführungsformen mit paarweise ausgebildeten Querkraft übertragenden Elementen (35) gilt es weiterhin als bevorzugt, wenn sich die das mindestens eine Paar bildenden Querkraft übertragenden Elemente (35) mittig innerhalb des mindestens einen Druckelements (33) kreuzend ausgebildet sind. 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,
  • teilweise von einem Paar aus mindestens zwei, bevorzugt aus genau zwei stabförmig ausgebildeten Querkraft übertragenden Elementen (35) durchzogen sind, die geradlinig über ihre vollständige Länge ausgebildet sind.
In the context of the embodiments with pairs of transverse force-transmitting elements (35), it is furthermore preferred if the elements (35) transmitting the at least one pair of transverse forces are formed crossing inside the at least one pressure element (33). In this case, it is conceivable, in particular, that in the case of a plurality of pressure elements (33) penetrating the insulation bodies (31), these pressure elements (33)
  • partially by a pair of at least two, preferably from exactly two rod-shaped transverse force transmitting elements (35) are traversed, at least partially angled and formed within the respective pressure elements (33) crossing,
  • partially by a pair of at least two, preferably from exactly two rod-shaped transverse force transmitting elements (35) are crossed, which are formed in a straight line over its entire length.

Bei den sich stabförmig kreuzend ausgebildeten Querkraft übertragenden Elementen (35) ist es bevorzugt, wenn diese beiden Querkraft übertragenden Elemente (35) im Kreuzungspunkt entweder direkt kraftschlüssig miteinander verbunden sind, wofür sich eine Verklebung wie auch eine Verschweißung anbieten. 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.

Im Rahmen der Ausführungsformen mit paarweise ausgebildeten Querkraft übertragenden Elementen (35) gilt es des weiteren als bevorzugt, wenn die das mindestens eine Paar bildenden Querkraft übertragenden Elemente (35) beabstandet außerhalb des Isolationskörpers (31) mindestens einfach miteinander verbunden sind. Eine solche Verbindung der Querkraft übertragenden Elemente (35) außerhalb des Isolationskörpers (31) kann ganz besonders bevorzugt kombiniert werden mit der Ausführung, bei der sich die kreuzenden Querkraft übertragenden Elemente (35) durch jeweils kraftschlüssige Verbindung mit mindestens einem gemeinsamen Druckelement (33) indirekt kraftschlüssig miteinander verbunden sind. Eine solche Verbindung der Querkraft übertragenden Elemente (35) außerhalb des Isolationskörpers (31) kann genauso zum einen besonders bevorzugt kombiniert werden mit der Ausführung, nach der die Querkraft übertragenden Elemente (35) mittig innerhalb des mindestens einen Druckelements (33) kreuzend ausgebildet sind, wie auch mit einer Ausführung, nach der die paarweise ausgebildeten Querkraft übertragenden Elemente (35) bis zu ihrer gegenseitigen außerhalb des Isolationskörpers (31) beabstandeten Verbindung geradlinig ausgebildet sind und dabei den Isolationskörper (31) insbesondere geradlinig und zueinander parallel durchdringen.In the context of the embodiments with pairs of transverse force-transmitting elements (35), it is further preferred that the elements (35) transmitting the at least one pair of transverse force are at least simply connected to each other at a distance outside the insulating body (31). Such a connection of the transverse force-transmitting elements (35) outside of the insulating body (31) can very particularly preferably be combined with the embodiment in which the transverse force-transmitting elements (35) are indirectly connected by at least one common pressure element (33) are positively connected with each other. Such a connection of the lateral force-transmitting elements (35) outside the insulating body (31) can be combined with the embodiment according to which the transverse force-transmitting elements (35) are formed centrally crossing within the at least one pressure element (33), as well as with a design according to which the pairs formed transverse force transmitting elements (35) to their mutual outside of the insulation body (31) spaced connection are rectilinear and thereby penetrate the insulation body (31) in particular straight and parallel to each other.

Gemäß einer bevorzugten Ausführungsvariante ist das Verhältnis

  • zwischen übertragbarer Druckkraft, hauptsächlich beeinflusst seitens der Druckelemente (33),
  • zu übertragbarer Querkraft, hauptsächlich beeinflusst seitens der Querkraft übertragenden Elemente (35) und ihrer kraftschlüssigen Verbindung zu den Druckelemente (33), jeweils gemessen in übertragbaren Krafteinheiten,
größer 2:1, vorzugsweise größer 4:1 und besonders bevorzugt größer 5:1. Das bedeutet, dass das erfindungsgemäße Anschlusselement (17) It. bevorzugter Ausführungsvariante mehr, besonders bevorzugt wesentlich mehr Druckkraft als Querkraft zu übertragen in der Lage ist. Die durch ein Element übertragbaren Krafteinheiten können bestimmt werden, indem die Elemente jeweils bis zum Bruch belastet werden.According to a preferred embodiment, the ratio
  • between transferable compressive force, mainly influenced by the pressure elements (33),
  • to transmittable shear force, mainly influenced by the lateral force transmitting elements (35) and their non-positive connection to the pressure elements (33), measured in each case in transferable units of force,
greater than 2: 1, preferably greater than 4: 1 and more preferably greater than 5: 1. This means that the connection element (17) according to the invention of the preferred embodiment variant is capable of transferring more, particularly preferably significantly more compressive force than transverse force. The units of force that can be transmitted by means of an element can be determined by loading the elements in each case until they break.

Das erfindungsgemäße Anschlusselement (17) kann als im Querschnitt polygoner Körper (z.B. hexagonal, octagonal) mit zwei einander gegenüberliegenden und zueinander parallelen ersten und zweiten Flachseiten ausgebildet sein, die den zwei sich gegenüberliegenden und den Isolationskörper (31) begrenzenden Auflageflächen (39, 41) entsprechen bzw. bei über die Auflageflächen (39, 41) hinausragenden Druckverteilplatten (51) parallel zu den beiden Auflageflächen (39, 41) gelegen sind. Vorteilhaft ist das erfindungsgemäße Anschlusselement (17) jedoch als quaderförmiger Körper ausgebildet. Dies hat den Vorteil, dass die Seitenflächen des Anschlusselements (17) mit den auf ihm ruhenden Betonwänden (15) fluchten können.The connecting element (17) according to the invention can be designed as a polygonal body in cross section (eg hexagonal, octagonal) with two opposite and mutually parallel first and second flat sides, which the two opposing and the insulating body (31) limiting bearing surfaces (39, 41). correspond or at more than the bearing surfaces (39, 41) protruding Druckverteilplatten (51) parallel to the two bearing surfaces (39, 41) are located. However, the connection element (17) according to the invention is advantageously designed as a parallelepiped body. This has the advantage that the side surfaces of the connecting element (17) can be aligned with the concrete walls (15) resting on it.

Die Erfindung ist gleichsam auch auf die Verwendung des hier vorgeschlagenen Druckkraft übertragenden Anschlusselements (17) in all seinen möglichen Ausführungsformen und Varianten als thermisch isolierende und gleichzeitig statisch versteifende Verbindungskomponente zwischen zwei bevorzugt übereinander positionierten gegossenen Bauteilen (13, 15, 29) gerichtet.The invention is also directed to the use of the here proposed compressive force-transmitting connection element (17) in all its possible embodiments and variants as a thermally insulating and at the same time stiffening connection component between two preferably superposed cast components (13, 15, 29).

Die nachfolgenden Figuren werden die Erfindung weitergehend erläutern:The following figures will further explain the invention:

Mit dem in Figur 5 wiedergegebenen erfindungsgemäßen Ausführungsbeispiel, welches eine vergleichbare Bausituation wiedergibt wie dargestellt in Figur 2, soll auf einer auf Erdreich angeordneten Betonbodenplatte (13) - als Beispiel für ein horizontales Betonbauteil - eine Betonwand (15) - als Beispiel für ein vertikales Betonbauteil - angeordnet sein, zwischen welchen ein erfindungsgemäßes, Druckkraft übertragendes Anschlusselement (17) positioniert ist. Das derart positionierte Anschlusselement (17) stellt einen quaderförmigen Körper mit einem niedrigen Wärmeleitkoeffizient von hier kleiner 60 mW/mK dar, welcher innerhalb der gezeigten Betonkonstruktion (11) das eine Betonteil (15) von einem angrenzenden Betonteil (13) thermisch abzutrennen vermag. An der Außenseite (19) der Betonwand (15) ist eine dem Stand der Technik entsprechende Außendämmung (21) angebracht, welche auch das Anschlusselement (17) größtenteils und vorzugsweise vollständig außenseitig abdeckt. Vorliegend überragt die Betonbodenplatte (13) die Betonwand (15) um ein bestimmtes Maß, und die Außendämmung (21) ist bis zur Betonbodenplatte (13) geführt. Auf der Betonbodenplatte (13) ist im Innenhausbereich eine Innendämmung (23) vorgesehen. Offensichtlich ist die hier dargestellte Betonkonstruktion (11) thermisch von der Umgebung vollständig getrennt. Somit entspricht die erfindungsgemäße Betonkonstruktion (11) gemäß dieser Figur 5 der thermisch optimalen Konstruktion gemäß Figur 1, da ebenfalls keine konstruktive Kältebrücke vorhanden ist.With the in FIG. 5 reproduced inventive embodiment, which reproduces a comparable construction situation as shown in FIG. 2 , Is to be arranged on a soil concrete floor slab (13) - as an example of a horizontal concrete component - a concrete wall (15) - as an example of a vertical concrete component - between which an inventive, compressive force transmitting connection element (17) is positioned. The thus positioned connecting element (17) is a cuboid body with a low heat transfer coefficient of less than 60 mW / mK, which within the shown concrete structure (11) which is able to thermally separate a concrete part (15) from an adjacent concrete part (13). On the outside (19) of the concrete wall (15) is a corresponding to the prior art external insulation (21) attached, which also covers the connection element (17) largely and preferably completely outside. In the present case, the concrete floor slab (13) projects beyond the concrete wall (15) by a certain amount, and the outer insulation (21) is led to the concrete floor slab (13). On the concrete floor slab (13) interior insulation (23) is provided in the interior house area.

Entsprechend ist die Innendämmung (23) nicht oberhalb, sondern unterhalb der Kellerdecke (29) angeordnet. Es ist wiederum ersichtlich, dass das Kellergeschoss (25) durch das Anschlusselement (17) und die Innendämmung (23) von der darüberliegenden Baukonstruktion thermisch isoliert ist.The concrete structure (11) according to the in FIG. 7 reproduced embodiment of the invention differs from the concrete structure (11) FIG. 6 in that now the basement ceiling (29) rests on a connection element (17) according to the invention which transmits compressive force.
