Description

Die Erfindung betrifft ein Anschlußelement mit einem Dämmkörper zur Verwendung als wärmedämmender Bauteil, insbesondere für Balkon- bzw. Kragplattenanschlüsse. Die Schwierigkeit liegt dabei darin, daß eine die beidseitigen Betonplatten verbindende Zugbewehrung und gegebenenfalls auch eine Schub- und Druckbewehrung eingebaut werden muß, die auch in dem den Dämmkörper durchsetzenden Abschnitt korrosionsbeständig sein muß. Ein Rostschutz durchgehend verlegter Bewehrungsstäbe durch den umhüllenden Beton verringert die Gesamtwärmedämmung des Bauteiles in einem hohen Ausmaß, da im Bereich der Zug-, Druck- und Schubbewehrung über die Höhe durchgehende Betonstege vorgesehen werden müßten, und sich die Dämmung auf die Zwischenbereiche beschränken würde.The invention relates to a connecting element with an insulating body for use as Insulating component, especially for balcony or cantilever panel connections. The The difficulty lies in the fact that one connects the concrete slabs on both sides Tension reinforcement and, if necessary, also shear and pressure reinforcement must be corrosion-resistant in the section penetrating the insulating body have to be. A rust protection through continuously laid reinforcement bars the surrounding concrete reduces the overall thermal insulation of the component in one high extent, because in the area of the tensile, pressure and shear reinforcement over the height continuous concrete webs would have to be provided, and the insulation on the Would restrict intermediate areas.

Aus der DE-A 34 26 538 ist ein Anschlußelement bekannt geworden, dessen Dämmkörper an der Oberseite Quernuten aufweist, in die bei der Verlegung an der Baustelle Zugbewehrungsstäbe eingelegt werden können. Versetzte Ausnehmungen an der Unterseite lassen als Drucklager durchgehende, unbewehrte Betonbalken entstehen, sodaß Unterbrechungen des Dämmkörpers zwar nicht über die Höhe durchgehen, dennoch aber Kältebrücken mit großen Querschnitten ausbilden, wobei auf eine Schubbewehrung überhaupt verzichtet wird. Die Anschlußelemente sind jedoch leicht handhabbar, da keine Bewehrungsteile vorstehen.From DE-A 34 26 538 a connection element has become known, the insulating body has transverse grooves on the top, in which when laying at the construction site Tension reinforcement bars can be inserted. Offset recesses on the Underside creates unreinforced concrete beams as thrust bearings, so that interruptions of the insulation body do not go through the height, nevertheless form cold bridges with large cross sections, with one Shear reinforcement is dispensed with at all. However, the connection elements are light manageable, since no reinforcement parts protrude.

Als Alternative für die Betonumhüllung besteht die Möglichkeit, die Bewehrungsstäbe aus rostfreiem Stahl zu erzeugen und im Dämmkörper zu fixieren. Abgesehen von den beträchtlich höheren Produktionskosten ergeben sich hier Handhabungsprobleme aufgrund der Breite der Anschlußelemente, da die Bewehrungsstäbe, die von den angrenzenden Bewehrungen der Betonplatten getrennt sind, zusätzliche Verankerungslängen aufweisen müssen, um den erforderlichen Kraftschluß im Beton sicherzustellen.As an alternative to the concrete covering, there is the option of the reinforcing bars to be made of stainless steel and fixed in the insulating body. Except the There are considerably higher production costs here due to handling problems the width of the connecting elements, since the reinforcing bars that are adjacent to Reinforcements of the concrete slabs are separated, additional anchoring lengths must have to ensure the required adhesion in the concrete.

Bei einem Anschlußelement mit zumindest einer Quernut in der Oberseite kann erfindungsgemäß ein üblicher Bewehrungsstahl für die Zugbewehrung eingesetzt werden, wenn in jeder Quernut ein nach oben offener, rinnenförmiger Einsatzkörper angeordnet ist, dessen beiden Enden über den Dämmkörper überstehen. Somit kann als Zugbewehrung für den Übergang von der Gebäudedecke in die Balkonplatte eine Baustahlmatte od.dgl. verlegt werden, wobei zwar jeder Stab durch eine Betonumhüllung gegen Korrosion geschützt wird, die Dicke der Betonumhüllung jedoch wesentlich geringer als für den Korrosionsschutz durch Beton allein erforderlich ist, da der rinnenförmige Einsatzkörper den Zutritt von Feuchtigkeit und Luft zum Umhüllungsbeton parallel zum Stabumfang verhindert. Eine Betonumhüllung in einer Dicke von ca. einem Zentimeter ist durchaus ausreichend, sodaß die Querschnittsfläche der durch die Betonumhüllung gebildeten Kältebrücke um ca. zwei Drittel verringert wird. Die Dämmung bzw. Abschirmung der Betonumhüllung wird über einen Bereich außerhalb des Dämmkörpers fortgesetzt, um auch in Längsrichtung des Zugbewehrungsstabes den Zutritt von Feuchtigkeit und Luft zum Bewehrungsstab auszuschließen. Der Überstand des rinnenförmigen Einsatzkörpers über den Dämmkörper entspricht daher zumindest dem üblichen Betonumhüllungsmaß, beispielsweise 2 cm.In the case of a connecting element with at least one transverse groove in the upper side, the invention can be used a common reinforcing steel can be used for the tensile reinforcement, if a channel-shaped insert body open at the top is arranged in each transverse groove is, the two ends of which protrude beyond the insulating body. Thus, as Tension reinforcement for the transition from the building ceiling to the balcony slab Structural steel mat or the like be laid, each rod by a Concrete casing is protected against corrosion, the thickness of the concrete casing however much less than is required for corrosion protection by concrete alone is because the channel-shaped insert body prevents the entry of moisture and air Wrapping concrete prevented parallel to the bar circumference. A concrete covering in one Thickness of about one centimeter is quite sufficient so that the Cross-sectional area of the cold bridge formed by the concrete covering by approximately two Third is reduced. The insulation or shielding of the concrete covering is over an area outside the insulating body continued to also in the longitudinal direction of the Tensile reinforcement bar the access of moisture and air to the reinforcement bar excluded. The protrusion of the channel-shaped insert body over the Insulating body therefore corresponds at least to the usual concrete covering dimension, for example 2 cm.

Für die Distanzierung des Stabes vom Einsatzköper weist dieser bevorzugt nach innen ragende Zentriervorsprünge auf.For the distance of the rod from the insert body, this shows prefers inwardly projecting centering projections.

Nachstehend wird nun die Erfindung an Hand der Figuren der beiliegenden Zeichnungen näher beschrieben, ohne darauf beschränkt zu sein.The invention will now be described with reference to the figures in the accompanying drawings described in more detail without being limited thereto.

    • Ein Anschlußelement weist einen Dämmkörper 1 auf, dessen Höhe der Dicke der Gebäudedecke bzw. Balkon- oder Kragplatte entspricht, und dessen Länge (in Längsrichtung der Gebäudewand), insbesondere dem Gitterabstand eines als obere Gebäudedeckenbewehrung dienenden Baustahlgitters entspricht, also beispielsweise 15 oder 20 cm beträgt. Der Dämmkörper ist insbesondere aus zwei Teilen 1' zusammengesetzt, die entlang ihrer Berührungsflächen 11 miteinander verbunden, insbesondere verklebt sind.A connection element has an insulating body 1, the height of the thickness of the building ceiling or balcony or cantilever plate, and its length (in the longitudinal direction the building wall), in particular the grid spacing of one as the upper building ceiling reinforcement serving structural steel grid, for example 15 or 20 cm. The insulating body is in particular made of two parts 1 ' composed, which are connected to one another along their contact surfaces 11, in particular are glued.

    Der Dämmkörper ist im unteren Bereich von mindestens einem druckbewehrenden Stab 3 durchsetzt, dessen beide annähernd gleich weit aus dem Dämmkörper 1 vorstehende Enden jeweils mit einer Druckplatte 4 versehen sind. Der Dämmkörper 1 ist weiters von einem etwa S-förmigen Schubbewehrungselement 2 durchsetzt, das beidseits des Dämmkörpers 1 mit dem druckbewehrenden Stab 3 verbunden ist. Das S-förmige Schubbewehrungselement 2 ist so angeordnet, daß das nach unten rückgebogene Ende in die Gebäudedecke eingebunden ist. Die Elemente 2, 3 sind in Ausnehmungen 12 (Fig. 4) der Berührungsflächen 11 der beiden Teile 1' des Dämmkörpers 1 eingelegt.The insulation body is in the lower area of at least one pressure reinforcing Rod 3 penetrates, both of which protrude approximately the same distance from the insulating body 1 Each end is provided with a pressure plate 4. The insulation body 1 is further penetrated by an approximately S-shaped shear reinforcement element 2, on both sides of the insulating body 1 is connected to the pressure-reinforcing rod 3. The S-shaped Shear reinforcement element 2 is arranged so that the bent back down End is integrated into the building ceiling. The elements 2, 3 are in recesses 12 (Fig. 4) of the contact surfaces 11 of the two parts 1 'of the insulating body 1 inserted.

    An der Oberseite weist der Dämmkörper 1 eine nach oben offene Quernut 5 auf, in der ein rinnenförmiger Einsatzkörper 6 angeordnet ist, der beidseitig um das Maß a aus dem Dämmkörper 1 vorsteht. In den Einsatzkörper 6 kann an der Baustelle ein Zugbewehrungsstab 7 eingelegt werden, der insbesondere ein überstehender Endbereich eines oberen Gebäudedeckenbewehrungsstabes ist. Besteht die obere Gebäudedeckenbewehrung aus einer Baustahlmatte, so kann diese in die Balkonoder Kragplatte durchgehend verlegt werden.At the top, the insulating body 1 has an upwardly open transverse groove 5 in which a trough-shaped insert body 6 is arranged, the dimension a on both sides protrudes the insulating body 1. In the insert body 6 can be at the construction site Tension reinforcement bar 7 are inserted, in particular a protruding End area of an upper building ceiling reinforcement bar is. Exists the top Ceiling reinforcement from a steel mesh, this can be in the balcony or Cantilever slab to be laid continuously.

    Durch den Einsatzkörper 6 wird eine Abschirmung des in den Einsatzkörper 6 einzubringenden Umhüllungsbeton gegen Feuchtigkeit und Luft erreicht, sodaß die Dicke b der Betonumhüllung des aus normalem, korrosionsfähigem Bewehrungsstahl bestehenden Zugbewehrungsstabes 7 wesentlich geringer sein kann, als für den Korrosionsschutz durch Beton allein vorgeschrieben ist. Wenn die Dicke b etwa die Hälfte der vorgeschriebenen Korrosionsschutzdicke beträgt, so reduziert sich die Betonquerschnittsfläche um etwa zwei Drittel, sodaß die unumgängliche Kältebrücke wesentlich verkleinert ist.The insert body 6 shields the element to be inserted into the insert body 6 Cladding concrete against moisture and air is reached so that the thickness b the concrete covering of the normal, corrosion-resistant reinforcing steel Tension reinforcement bar 7 can be significantly less than for corrosion protection is prescribed by concrete alone. If the thickness b is about half the specified corrosion protection thickness, the concrete cross-sectional area is reduced by about two thirds, making the inevitable cold bridge essential is reduced.

    Durch den beidseitigen Überstand des Einsatzkörpers 6 über den Dämmkörper 1 um das Maß a, das zumindest dem vorgeschriebenen Betonumhüllungsmaß entspricht, wird der Zutritt von Feuchtigkeit und Luft zum Zugbewehrungsstab 7 auch von den Stimseiten vermieden. Die Überdeckung des Zugbewehrungsstabes 7 ist mit der vorgeschriebenen Dicke möglich, wobei eine seitliche Teilabschirmung durch die schräg zueinander gerichteten Längsrandbereiche 10 des Einsatzkörpers 6 zusätzlich gegeben ist.Due to the protrusion of the insert body 6 on both sides over the insulating body 1 dimension a, which corresponds at least to the prescribed concrete cladding dimension, the access of moisture and air to the tensile reinforcement bar 7 is also from the Avoid face pages. The overlap of the tensile reinforcement bar 7 is prescribed Thickness possible, with a partial shielding through the oblique longitudinal edge regions 10 of the insert body 6 facing each other are additionally provided is.

    Der Einsatzkörper 6 ist mit nach innen ragenden Zentriervorsprüngen 8 versehen, um den Zugbewehrungsstab 7 in der die ausreichende Betonumhüllung gewährleistenden Position zu halten. Der Druckstab 3, die Druckplatten 4, das Schubbewehrungselement 2 und der Einsatzkörper 6 können aus rostfreiem Stahl bestehen oder einen korrosionshemmenden Überzug aufweisen. Weiters können insbesondere der Einsatzkörper 6 und die Druckplatten 4 auch aus einem geeigneten Kunststoff bestehen.The insert body 6 is provided with inwardly projecting centering projections 8 the tensile reinforcement bar 7 in which ensure the sufficient concrete covering Hold position. The pressure rod 3, the pressure plates 4, the Shear reinforcement element 2 and the insert body 6 can be made of stainless steel exist or have a corrosion-resistant coating. Furthermore can in particular the insert body 6 and the pressure plates 4 also from a suitable one Plastic.

    In der Ausführung nach Fig. 5 und 6 ist der rinnenförmige Einsatzkörper 6 mit größerem Überstand über den Dämmkörper 1 dargestellt, sodaß er mit dem Schubbewehrungselement 2 verbunden werden kann. Dies erhöht die Stabilität des Anschlußelementes und bildet eine Transport- und Montageverstärkung.5 and 6, the trough-shaped insert body 6 is larger Projecting over the insulating body 1 shown, so that it with the shear reinforcement element 2 can be connected. This increases the stability of the connection element and forms a transport and assembly reinforcement.

    Jede Druckplatte 4 muß aufgrund der notwendigen gleichmäßigen Kraftumlenkung in den Druckstab 3 so angeordnet sein, daß ihr Schwerpunkt in der Stabachse liegt. Die Druckplatten 4 weisen daher zwangsläufig eine vertikale Erstreckung rund um den Druckstab 3 auf, die einerseits zur Festlegung eines Abstands zur Betonschalung eingesetzt werden kann, andererseits aber Platzprobleme bereiten kann, beispielsweise wenn die Gebäudedecke eine Fertigteilplattenschalung 9 aufweist, wie in Fig. 5 angedeutet, usw. Erfindungsgemäße Druckplatten 4 weisen daher eine Umfangslinie auf, deren Abstand zum Schwerpunkt unterschiedlich ist, wobei das Verhältnis des Minimalabstandes zum Maximalabstand mindestens 1:2 beträgt.Each pressure plate 4 must be in due to the necessary uniform force deflection the pressure rod 3 should be arranged so that its center of gravity lies in the rod axis. The Printing plates 4 therefore inevitably have a vertical extension around the Pressure rod 3, which is used on the one hand to set a distance to the concrete formwork can, but on the other hand can cause space problems, for example if the building ceiling has a prefabricated panel formwork 9, as indicated in FIG. 5, etc. printing plates 4 according to the invention therefore have a circumferential line, their distance from the center of gravity is different, the ratio of the minimum distance to the maximum distance is at least 1: 2.

    Besonders günstige Verhältnisse ergeben sich, wenn die Druckplatte 4, die in Figur 6 gezeigte Form eines gleichseitigen Dreiecks aufweist, in dem der Schwerpunkt von jeder Ecke doppelt so weit entfernt ist wie von der gegenüberliegenden Seite. Maximum und Minimum des radialen Überstands der Druckplatte 4 über den Druckstab 3 verhalten sich in der gezeigten Ausführung etwa wie 1:3. Somit läßt sich beispielsweise der maximale radiale Überstand zur Festlegung des Abstands verwenden, der für die Betonumhüllung des Druckstabes erforderlich ist (linke Seite der Fig. 5), wenn die dreieckige Druckplatte 4 mit einer Ecke auf einer Betonschalung aufsteht. An der rechten Seite ist die Druckplatte 4 um 180° gedreht (Fig. 6) und daher mit minimalem Überstand nach unten vorgesehen. Es genügt, wie gezeigt, eine leichte Aufbiegung des Druckstabes 3 um die Druckplatte 4 beispielsweise über einer verlorenen Betonplattenschalung 9 anordnen zu können.Particularly favorable conditions result when the pressure plate 4 shown in FIG shown shape of an equilateral triangle, in which the center of gravity of each corner is twice as far from the opposite side. maximum and minimum of the radial projection of the pressure plate 4 over the pressure rod 3 behave like 1: 3 in the version shown. Thus, for example use the maximum radial overhang to determine the distance that is required for the concrete casing of the pressure rod (left side of FIG. 5), if the triangular pressure plate 4 stands up with a corner on a concrete formwork. At the right side, the pressure plate 4 is rotated by 180 ° (Fig. 6) and therefore with minimal Projection provided downwards. As shown, a slight bend is sufficient of the pressure rod 3 around the pressure plate 4, for example over a lost concrete slab formwork 9 to be able to arrange.

    Das erfindungsgemäße Anschlußelement ist einerseits verhältnismäßig klein, handlich, platzsparend transportierbar und einfach verlegbar, da nur die Schub- und Druckbewehrung 2, 3 aus dem Dämmkörper 1 beidseitig vorstehen, nicht aber eine beidseitige, wesentlich längere Zugbewehrung als Bestandteil des Anschlußelements vorgesehen ist, und läßt andererseits durch eine kleinstmögliche Betonumhüllung der durchgehenden Zugbewehrungsstäbe 7 minimale Kältebrücken entstehen.On the one hand, the connection element according to the invention is relatively small, handy, space-saving transportable and easy to lay, because only the shear and pressure reinforcement 2, 3 protrude from the insulating body 1 on both sides, but not one on both sides, much longer tensile reinforcement provided as part of the connecting element is, and on the other hand lets the smallest possible concrete coating the continuous reinforcement bars 7 minimal cold bridges arise.
