Description

Die Erfindung betrifft eine Anordnung zum kraftschlüssigen Anschluss eines Bauteils an einen Baukörper gemäß dem Oberbegriff des Patentanspruchs 1.
Derartige Anschlüsse sind dem Gebiet des Bauwesens zuzuordnen, wo vor allem im Hochbau häufig die Notwendigkeit besteht, an einen bestehenden Baukörper nachträglich ein Bauteil anzuschließen. Der Baukörper wird dabei im Regelfall von einem Bauwerk gebildet, an dessen Wände, Stützen oder Decken Bauteile wie zum Beispiel Balkone, Galerien und dergleichen angeschlossen werden sollen. Sowohl Bauteil als auch Baukörper bestehen in den überwiegenden Fällen aus Beton oder einer Stahlkonstruktion.
Zur Herstellung eines aus einem Baukörper auskragenden Bauteils wie zum Beispiel eines Balkons ist seit langem die monolithische Bauweise bekannt. Dabei wird durch geeignete Formgebung der Schalung das Bauteil zusammen mit dem entsprechenden Teil des Baukörpers betoniert und über eine ausreichende Bewehrung fest mit dem Baukörper verbunden. Aus bauphysikalischer Sicht birgt diese Art der Konstruktion jedoch die Gefahr, dass das Bauteil eine Wärmebrücke darstellt, so dass man auch schon dazu übergegangen ist, das Bauteil nachträglich an den Baukörper anzuschließen und den Bauteilanschluss bereits bei der Herstellung des Baukörpers durch eine geeignete Anschlusskonstruktion zu berücksichtigen. Eine derartige Lösung ist beispielsweise aus der DE 196 30 552 A1 bekannt, bei der zwischen Baukörper und Bauteil die Anordnung eines thermisch isolierenden Elements vorgesehen ist, welches lediglich von einer Anschlussbewehrung durchdrungen ist. In beiden Fällen sind die Bauteile mit einer schlaffen Bewehrung armiert, was aus statischen Gründen in Abhängigkeit der vorhandenen Spannweiten zu verhältnismäßig großen Bauteildicken führt, was aus ästhetischen Gründen nicht immer vorteilhaft ist.The invention relates to an arrangement for the non-positive connection of a component to a building according to the preamble of patent claim 1.
Such connections are assigned to the field of construction, where especially in structural engineering there is often the need to subsequently connect a component to an existing structure. The structure is usually formed by a structure on the walls, columns or ceilings components such as balconies, galleries and the like to be connected. Both component and structure consist in the majority of cases of concrete or a steel construction.
To produce a cantilevered from a building component such as a balcony monolithic construction has long been known. In this case, the component is concreted together with the corresponding part of the structure by suitable shaping of the formwork and connected via a sufficient reinforcement firmly with the building. From a building physics point of view, however, this type of construction entails the risk that the component represents a thermal bridge, so that one has already gone over to subsequently connect the component to the building and to consider the component connection already in the manufacture of the building by a suitable connection construction , Such a solution is for example from the DE 196 30 552 A1 known, in which the arrangement of a thermally insulating element is provided between the structural body and component, which is penetrated only by a connection reinforcement. In both cases, the components are reinforced with a flaccid reinforcement, resulting in static reasons, depending on the existing spans to relatively large component thicknesses, which is not always advantageous for aesthetic reasons.

Die FR 2 868 448 beschreibt eine Vorrichtung, bestehend aus einem Dämmstoffelement mit einem Isolierkörper für eine wärmeisolierende Befestigung einer Bodenplatte an einer vertikalen Wand. Die Vorrichtung umfasst insbesondere einen wärmeisolierenden Körper, der mit den Seiten gegen ein Bauteil befestigt ist. Ferner sind Einbrandkerben entlang einer der Seiten des Körpers vorgesehen. Die Einbrandkerben sind voneinander beabstandete Vorsprünge, die den tragenden Boden bilden. Die Einbrandkerben sind nach unten durch Gleitplatten geschlossen, die auf Druck thermoisolierend und widerstandsfähig sind.The FR 2 868 448 describes a device consisting of an insulating element with an insulating body for a thermally insulating attachment of a bottom plate to a vertical wall. The device comprises in particular a heat-insulating body, which is fastened with the sides against a component. Further, scorches are provided along one of the sides of the body. The Einbrandkerben are from each other spaced projections that form the supporting floor. The scorches are closed at the bottom by sliding plates which are thermo-insulating and resistant to pressure.

Die Druckschrift STUDIENVEREIN FÜR DAS BAUEN MIT BETONFERTIGTEILEN: "Kraftschlüssige Verbindungen im Hochbau" (BETON-VERLAG GMBH, 1. Jan. 1978 (01.01.1978), S. 92, 93, 156 und 157, XP007921378, ISBN: 3764001127 ) beschreibt ein Verfahren zur Verbindung von Balken mit Stützen durch Gewindestäbe oder Spannstäbe. Das Verfahren betrifft einen Anschluss linearer Bauteile (z. B Balken) an Fertigteilstützen, so dass sich dort aufgrund des punktuellen Anschlusses die Problematik von Spannungen infolge temperaturbedingter Längenänderungen des Bauteils nicht ergibt.The publication STUDY ASSOCIATION FOR CONSTRUCTION WITH CONCRETE FINISHED PARTS: "Non-positive connections in building construction" (BETON-VERLAG GMBH, Jan. 1, 1978 (01.01.1978), p. 92, 93, 156 and 157, XP007921378, ISBN: 3764001127 ) describes a method for connecting beams to columns by threaded rods or tie rods. The method relates to a connection of linear components (eg beams) to precast columns, so that due to the point-to-point connection there is no problem of stresses due to temperature-induced changes in length of the component.

Die EP 1 039 056 betrifft einen Balkon, der zwei einander gegenüberliegend angeordnete Seiten aufweist. Eine Seite ist gegen eine Außenwand angeordnet. Die Seite ist zur Verbindung zwischen dem Balkon und der Außenwand mittels eines Befestigungsstabs angeordnet. Der Befestigungsstab ist von einer Seite des Balkons bis zur anderen Seite des Balkons verlängert.The EP 1 039 056 relates to a balcony having two oppositely disposed sides. One side is arranged against an outer wall. The side is arranged for connection between the balcony and the outer wall by means of a fixing rod. The fixing rod is extended from one side of the balcony to the other side of the balcony.

Darüber hinaus ist aus dem Stand der Technik bekannt, die Befestigung eines Bauteils mittels Spannanker vorzunehmen, die gegen den Baukörper vorgespannt werden. Neben dem Vorteil, dass das Bauteil als Fertigteil nachträglich montiert werden kann und daher den übrigen Bauablauf nicht stört, können vorgespannte Bauteile konstruktiv schlanker ausgebildet werden, da die spezifische Eigenschaft des Betons, hohe Druckkräfte aufnehmen zu können, besser ausgenutzt wird.In addition, it is known from the prior art to make the attachment of a component by means of clamping anchor, which are biased against the building. In addition to the advantage that the component can be retrofitted as a finished part and therefore does not interfere with the rest of the construction process, prestressed components can be structurally made leaner, as the specific property of the concrete to absorb high pressure forces, is better utilized.

Als problematisch erweist sich dabei jedoch die Anschlussfuge im Kraftübertragungsbereich. Dort konzentrieren sich infolge der Spannkräfte hohe Druckspannungen, die im Regelfall über einen hochfesten Verguss im Bereich der Spannanker vom Bauteil in den Baukörper eingetragen werden. Ähnlich einem monolithischen Anschluss bilden die Kraftübertragungsbereiche Wärmebrücken aus mit den bekannten Nachteilen. Darüber hinaus stellen die Kraftübertragungsbereiche Fixpunkte dar, die eine wärmebedingte Längenänderung des Bauteils behindern. Risse im Bereich zwischen den Kraftübertragungsbereichen sind daher die Folge, die aufwändig saniert werden müssen.However, the connecting joint in the power transmission area proves to be problematic. There, due to the clamping forces, high compressive stresses are concentrated, which as a rule are entered from the component into the structure via a high-strength encapsulation in the area of the clamping anchors. Similar to a monolithic connection, the power transmission areas form thermal bridges with the known disadvantages. In addition, the power transmission areas are fixed points that hinder a heat-related change in length of the component. Cracks in the area between the power transmission areas are therefore the result, which must be renovated consuming.

Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, einen Anschluss eines Bauteils an einen Baukörper mittels Spannelementen zu schaffen, der die beschriebenen Nachteile und Probleme überwindet.Against this background, the invention has for its object to provide a connection of a component to a building by means of clamping elements, which overcomes the disadvantages and problems described.

Diese Aufgabe wird durch eine Anordnung mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved by an arrangement having the features of patent claim 1.

Vorteilhafte Ausführungsformen ergeben sich aus den Unteransprüchen.Advantageous embodiments will be apparent from the dependent claims.

Der Grundgedanke der Erfindung besteht darin, die Anschlussfuge der Kraftübertragungsbereiche konstruktiv so zu gestalten, dass Gleitlager entstehen, die Bewegungen des Bauteils gegenüber dem Baukörper in Längserstreckungsrichtung der Anschlussfuge zulassen. Dazu müssen nicht alle Kraftübertragungsbereiche die Funktion eines Gleitlagers gewährleisten. Beispielsweise genügt es bei einem Anschluss eines Bauteils mittels zwei Kraftübertragungsbereichen bereits, wenn lediglich ein Kraftübertragungsbereich ein Gleitlager bildet, während der andere ein festes Lager darstellt. Erfindungsgemäß bevorzugt sind jedoch Anordnungen, bei denen alle Kraftübertragungsbereiche einen einheitlichen Aufbau in Form eines Gleitlagers zeigen. Die dadurch möglichen Relativbewegungen des Bauteils gegenüber dem Baukörper verhindern eine Rissbildung zwischen den Kraftübertragungsbereichen infolge wärmebedingter Längenänderungen. Gleichzeitig erhöhen die Gleitlager den Widerstand für die Wärmeleitung vom Baukörper zum Bauteil, wodurch die unerwünschten Folgen einer Wärmebrückenbildung erheblich verringert werden.The basic idea of the invention is to structurally design the connecting joint of the power transmission areas in such a way that sliding bearings are created which permit movements of the component with respect to the building body in the longitudinal direction of extension of the connecting joint. Not all power transmission areas need to ensure the function of a plain bearing. For example, it is sufficient for a connection of a component by means of two power transmission areas already, if only one power transmission area forms a sliding bearing, while the other is a solid bearing. According to the invention, however, arrangements are preferred in which all power transmission areas show a uniform structure in the form of a sliding bearing. The resulting relative movements of the component relative to the structure prevent cracking between the power transmission areas as a result of heat-related changes in length. At the same time, the slide bearings increase the resistance to heat conduction from the structure to the component, which significantly reduces the undesirable consequences of thermal bridge formation.

Die Ausbildung erfindungsgemäßer Gleitlager unter den gegebenen Umständen erweist sich auf den ersten Blick als ungewöhnlich, da einerseits durch eine möglichst geringe Haftreibung in der Anschlussfuge erreicht werden soll, dass Relativbewegungen des Bauteils zum Baukörper nicht behindert werden, andererseits die aus den Spannelementen kommenden Druckkräfte naturgemäß die Haftreibung erhöhen. Um diese sich widersprechenden Anforderungen zu vereinen, ist gemäß der Erfindung vorgesehen, zur Ausbildung eines Gleitlagers eine Materialpaarung in der Anschlüssfuge zu wählen, bei der der Haftreibungskoeffizient weniger als 0,2 beträgt, vorzugsweise weniger als 0,1. Hierzu geeignete Materialien sind beispielsweise Polytetrafluorethylen, Polyethylen, Polyamid, Nylon, Polyethylenterephtalat oder Polyacetal. Die verwendeten Materialien können durch eingelagerte Schmierestoffe selbstschmierend sein oder durch Integration von Gleitfasern, beispielsweise Polytetrafluorethylenfasern, den Haftreibungsbeiwert weiter verringern. Um eine Vernetzung der baukörperseitigen Lagerfläche und der bauteilseitigen Auflagerfläche zu vermeiden, sieht die Erfindung in vorteilhafter Weiterbildung vor, für die Lagerflächen und Auflagerflächen unterschiedliche Materialien zu verwenden.The formation of inventive sliding bearing under the circumstances proves to be unusual at first glance, since the lowest possible static friction in the connecting joint is to be achieved that relative movements of the component are not hindered to the building, on the other hand coming from the clamping elements pressure forces naturally the Increase stiction. In order to unite these contradictory requirements, it is provided according to the invention to select a material pairing in the connecting joint, in which the coefficient of static friction is less than 0.2, preferably less than 0.1, to form a plain bearing. Suitable materials for this purpose are, for example, polytetrafluoroethylene, polyethylene, polyamide, nylon, polyethylene terephthalate or polyacetal. The materials used can be self-lubricating by incorporated lubricants or by Integration of sliding fibers, such as polytetrafluoroethylene fibers, further reduce the coefficient of static friction. In order to avoid cross-linking of the body-side bearing surface and the component-side support surface, the invention provides, in an advantageous embodiment, to use different materials for the bearing surfaces and bearing surfaces.

Gemäß einer vorteilhaften Ausführungsform der Erfindung werden die ersten Lagerflächen zur Aufnahme vertikaler Kräfte durch einen horizontalen Versatz in der Baukörperoberfläche nach innen verlagert. Auf diese Weise ergibt sich eine gedrungene Bauweise, bei der die Gleitlager nicht mehr von außen sichtbar sind, was den ästhetischen Gesamteindruck verbessert. Darüber hinaus sind die Gleitlager auf diese Weise vor Umwelteinflüssen wie Nässe, Schmutz und dergleichen geschützt.According to an advantageous embodiment of the invention, the first bearing surfaces for receiving vertical forces are displaced inwardly by a horizontal offset in the structural surface. In this way, a compact construction, in which the plain bearings are no longer visible from the outside, which improves the overall aesthetic impression. In addition, the bearings are protected in this way from environmental influences such as moisture, dirt and the like.

Denkbar ist, dass sich der durch einen horizontalen Versatz gebildete Rücksprung in der Baukörperoberfläche durchgehend über den gesamten, durch den Abstand zweier Kraftübertragungsbereiche definierten Baukörperabschnitt erstreckt. Bevorzugt ist jedoch eine nischenartige Ausbildung der Kraftübertragungsbereiche, das heißt der Rücksprung in der Oberfläche des Baukörpers erstreckt sich lediglich über einen Kraftübertragungsbereich. Der aus dem Bauteil ragende Vorsprung zur Ausbildung des Gleitlagers ist in diesem Fall beidseitig zwischen den Seitenwänden des nischenartigen Rücksprungs eingebettet. Dabei sorgt ein Spalt zwischen der Nischenwand und dem Vorsprung für ausreichend Raum, um eine wärmebedingte Längenänderung des Bauteils zuzulassen. In vorteilhafter Weiterbildung der Erfindung kann dieser Spalt auch mit einem verformbaren Material verfüllt sein.It is conceivable that the return formed by a horizontal offset in the surface of the building surface extends continuously over the entire, defined by the distance of two power transmission areas structure section. Preferably, however, a niche-like design of the power transmission areas, that is, the recess in the surface of the building extends only over a power transmission area. The protruding from the component projection to form the sliding bearing is embedded in this case on both sides between the side walls of the niche-like recess. In this case, a gap between the niche wall and the projection provides sufficient space to allow a heat-related change in length of the component. In an advantageous development of the invention, this gap can also be filled with a deformable material.

Eine vorteilhafte Ausführungsform der Erfindung sieht vor, die kraftübertragenden Bereiche des Bauteils und/oder des Baukörpers, die die Lagerflächen und Auflagerflächen tragen, als Einbauteil, beispielsweise aus Beton oder Stahl auszubilden und diese im Zuge der Herstellung des Baukörpers oder Bauteils durch Einbetonieren oder Anschweißen bzw. Anschrauben zu fixieren. Dies gestattet eine hochpräzise Fertigung der Flächen im Kraftübertragungsbereich. Zudem kann für diese Bereiche eine vom übrigen Baukörper bzw. Bauteil abweichende Materialwahl erfolgen, um eine Anpassung an die spezifischen Anforderungen im Kraftübertragungsbereich vorzunehmen. Beispielsweise können diese Bereiche von einem hochfesten Beton zur Aufnahme und Ableitung der vorhanden Druckkräfte gebildet sein oder von einem umweltresistenten Beton oder Stahl.An advantageous embodiment of the invention provides for the force-transmitting areas of the component and / or the building, which carry the bearing surfaces and bearing surfaces, as a built-in part, for example made of concrete or steel and this in the course of the production of the building or component by casting or welding or Screw on to fix. This allows a high-precision production of the surfaces in the power transmission area. In addition, a deviating from the rest of the building or component material choice can be made for these areas to make an adjustment to the specific requirements in the power transmission area. For example, these areas may be made of a high strength concrete for uptake and Derivation of existing compressive forces may be formed or of an environmentally resistant concrete or steel.

Daneben ist es auch möglich, die der Anschlussfuge zugeordneten Bereiche des Baukörpers und/oder Bauteils zunächst auszusparen und dann durch einen nachträglichen Verguss herzustellen. Dies bringt den Vorteil, dass für diese Bereiche ebenfalls besonders geeignete Baustoffe verwendet werden können. Darüber hinaus kommen bei einem nachträglichen örtlichen Verguss Montage- und Herstellungsungenauigkeiten nicht in dem Maße zum Tragen, da Maßabweichungen über die Länge des Vergusses ausgeglichen werden können. In vorteilhafter Weiterbildung der Erfindung ist daher vorgesehen, den die Zugelemente umgebenden Bereich des Baukörpers von der Anschlussfuge bis mindestens 20 cm, vorzugsweise 40 cm in den Baukörper hinein zunächst als Vertiefung auszubilden, die später vergossen wird.In addition, it is also possible to first save the joints of the building structure and / or component associated with the connecting joint and then produce it by subsequent encapsulation. This has the advantage that particularly suitable building materials can be used for these areas. In addition, in a subsequent local encapsulation assembly and manufacturing inaccuracies are not to the extent to bear because deviations over the length of the encapsulation can be compensated. In an advantageous embodiment of the invention is therefore intended to form the tensile elements surrounding region of the structure of the connecting joint to at least 20 cm, preferably 40 cm into the building initially as a depression, which is later shed.

Die Spannelemente selbst sind innerhalb des Baukörpers und/oder Bauteils in den an die Anschlussfuge angrenzenden Bereichen innerhalb eines Kanals mit ausreichend lichtem Abstand zur Kanalwandung geführt, damit Relativbewegungen des Bauteils gegenüber dem Baukörper keine Zwängungen im Bereich der Spannelemente erfahren. Gemäß einer alternativen Ausführungsform der Erfindung wird das gleiche Ziel mit einer Ummantelung der Spannelemente aus einem verformbaren Material erreicht, beispielsweise mit einer Ummantelung aus Schaumstoff.The clamping elements themselves are guided within the structure and / or component in the adjoining the connecting joint areas within a channel with sufficient clearance to the channel wall, so that relative movements of the component relative to the building undergo no constraints in the region of the clamping elements. According to an alternative embodiment of the invention, the same goal is achieved with a sheathing of the clamping elements of a deformable material, for example with a sheath of foam.

Fig. 1 zeigt im Überblick einen horizontalen Schnitt durch einen Baukörper 1, der im vorliegenden Beispiel von einer Stahlbetondecke 2 eines Gebäudes gebildet ist. Die vertikale Gebäudeaußenseite ist dabei mit 3 gekennzeichnet. Weiter zeigt Fig. 1 ein plattenförmiges Bauteil 4, beispielweise zur Bildung eines Balkons, das als Stahlbetonfertigteil oder als Stahlkonstruktion mit seiner Längsseite 5 in der Ebene der Stahlbetondecke 2 an den Baukörper 1 kraftschlüssig angeschlossen ist. Die Längserstreckungsrichtung des Bauteils 4 parallel zur Gebäudeaußenseite 3 ist mit L bezeichnet. Fig. 1 shows an overview of a horizontal section through a building 1, which is formed in the present example of a reinforced concrete floor 2 of a building. The vertical exterior of the building is marked with 3. Next shows Fig. 1 a plate-shaped component 4, for example, to form a balcony, which is non-positively connected as a precast concrete or steel construction with its longitudinal side 5 in the plane of the reinforced concrete ceiling 2 to the building 1. The longitudinal direction of the component 4 parallel to the building exterior 3 is denoted by L.

Die für die Befestigung des Bauteils 4 notwendige Kraftübertragung erfolgt bei dem beschriebenen Ausführungsbeispiel in zwei Kraftübertragungsbereichen, die in horizontalem seitlichem Abstand zueinander angeordnet sind und von denen einer in Fig. 1 mit der Linie 6 kenntlich gemacht ist. Bei Bauteilen 4 mit größerer Längserstreckungsrichtung L können auch drei, vier oder mehr Kraftübertragungsbereiche 6 vorgesehen sein. Der seitliche Abstand der einzelnen Kraftübertragungsbereiche ist abhängig von der Größe der Längserstreckung L und liegt in der Regel zwischen 2 m und 4 m.The necessary for the attachment of the component 4 power transmission takes place in the described embodiment in two power transmission areas, which are arranged in a horizontal lateral distance from each other and of which one in Fig. 1 marked with the line 6. In the case of components 4 with a greater longitudinal direction L, three, four or more force transmission regions 6 can also be provided. The lateral distance of the individual power transmission areas is dependent on the size of the longitudinal extent L and is usually between 2 m and 4 m.

Der genauere Aufbau der Kraftübertragungsbereiche 6 ist zusätzlich in den Fig. 2 und 3 dargestellt. Jeder Kraftübertragungsbereich 6 wird von einer Nische 7 in der Gebäudeaußenseite 3 gebildet. Wie vor allem aus Fig. 2 hervor geht, ergibt deren stufenförmiger Verlauf eine obere vertikale Lagerfläche 8, die sich ausgehend von der Oberseite der Stahlbetondecke 2 in Richtung Unterseite erstreckt. An die obere vertikale Lagerfläche 8 schließt eine horizontale Lagerfläche 9 an, die in Richtung zur Unterseite der Stahlbetondecke 2 in eine untere vertikale Lagerfläche 10 übergeht. Die obere vertikale Lagerfläche 8 ist somit gegenüber der Gebäudeaußenseite 3 horizontal zurück versetzt. Im vorliegenden Ausführungsbeispiel weist auch die untere vertikale Lagerfläche 10 zu ihrem Schutz einen geringfügigen Versatz gegenüber der Gebäudeaußenseite 3 auf.The detailed structure of the power transmission areas 6 is additionally in the Fig. 2 and 3 shown. Each power transmission area 6 is formed by a niche 7 in the building exterior 3. Especially from Fig. 2 it emerges, their step-shaped course results in an upper vertical bearing surface 8, which extends from the top of the reinforced concrete slab 2 in the direction of the underside. To the upper vertical bearing surface 8 includes a horizontal bearing surface 9, which in the direction of the bottom the reinforced concrete ceiling 2 merges into a lower vertical bearing surface 10. The upper vertical bearing surface 8 is thus offset from the building exterior 3 horizontally back. In the present embodiment also has the lower vertical bearing surface 10 for their protection a slight offset relative to the building exterior 3.

Die Lagerflächen 8 bis 10 werden von dünnen Platten gebildet, die in die entsprechenden Nischenseiten eingelegt sind. Das Material der Platten zeichnet sich durch seinen geringen Haftreibungskoeffizienten aus, um die Funktion eines Gleitlagers zu gewährleisten. Die Dicke der Platten beträgt beispielsweise maximal 2 mm, vorzugsweise maximal 1 mm. Im Sinne der Erfindung geeignete Materialien sind beispielsweise Polytetrafluorethylen, Polyethylen, Polyamid, Nylon, Polyethylenterephtalat oder ein Polyacetalhomopolymer. Während sich die obere vertikale Lagerfläche 8 und untere vertikale Lagerfläche 10 im Wesentlichen über die gesamte Länge der Nische 7 erstrecken, um eine möglichst großflächige Verteilung der horizontalen Spannkräfte zu erreichen, weist die horizontale Lagerfläche 9 eine in Richtung L geringere Längserstreckung auf, um Spannungsspitzen im Randbereich der horizontalen Lagerfläche 9 aufgrund montage- oder herstellungsbedingter Toleranzen zu begrenzen.The bearing surfaces 8 to 10 are formed by thin plates which are inserted into the corresponding niche sides. The material of the plates is characterized by its low static friction coefficient to ensure the function of a plain bearing. The thickness of the plates is, for example, a maximum of 2 mm, preferably a maximum of 1 mm. Materials suitable for the purposes of the invention are, for example, polytetrafluoroethylene, polyethylene, polyamide, nylon, polyethylene terephthalate or a polyacetal homopolymer. While the upper vertical bearing surface 8 and lower vertical bearing surface 10 extend substantially over the entire length of the niche 7 in order to achieve the largest possible distribution of the horizontal clamping forces, the horizontal bearing surface 9 has a longitudinal extension L in the direction L in order to avoid stress peaks in the niche Limit border area of the horizontal bearing surface 9 due to assembly or manufacturing tolerances.

Der Bereich der Stahlbetondecke 2, der zur Ausbildung der Nische 7 und damit der Lagerflächen 8 bis 10 dient, wird im vorliegenden Beispiel von einem nachträglichen Verguss 11 hergestellt, der bevorzugt eine Druckfestigkeit von mindestens 65 N/mm2 aufweist und/oder mit Stahlfasern verstärkt ist. Denkbar und im Rahmen der Erfindung liegend wäre es auch, diese Bereiche als Einbauteil in Form eines Betonfertigteils oder Stahlteils herzustellen, die im Zuge des Betonierens der Stahlbetondecke 2 deren integraler Bestandteil werden.The area of the reinforced concrete ceiling 2, which serves to form the niche 7 and thus the bearing surfaces 8 to 10, is produced in the present example by a subsequent potting 11, which preferably has a compressive strength of at least 65 N / mm 2 and / or reinforced with steel fibers is. Conceivable and within the scope of the invention, it would also be to produce these areas as a built-in part in the form of a precast concrete part or steel part, which become an integral part in the course of concreting the reinforced concrete ceiling 2.

Wie Figur 3 zeigt sind die seitlichen Stirnwände der Nischen 7 jeweils mit einem verformbaren Material 45, beispielsweise einem Schaumstoff, bedeckt, der Bewegungen des Bauteils 4 in den Nischen 7 in gewissem Umfang zulässt. Anstelle des verformbaren Materials 45 kann auch zwischen dem Bauteil 4 und den Stirnwänden der Nischen 7 jeweils ein freier Spalt gelassen werden.As FIG. 3 The lateral end walls of the niches 7 are each covered with a deformable material 45, for example a foam, which allows movements of the component 4 in the recesses 7 to a certain extent. Instead of the deformable material 45, a free gap can also be left between the component 4 and the end walls of the niches 7.

Das Bauteil 4 besitzt im Bereich seiner Längsseite 5 in den den Nischen 7 gegenüberliegenden Längsabschnitten jeweils einen Vorsprung 12 mit einer zur Nische 7 komplementären geometrischen Ausbildung, um ein Hineinreichen des Vorsprungs 12 in die Nische 7 zu ermöglichen. Der Vorsprung 12 besitzt eine von der Oberseite des Bauteils 4 ausgehende obere vertikale Auflagerfläche 13, die auf etwa halber Höhe des Bauteils 4 in eine horizontale Auflagerfläche 14 übergeht. Daran schließt sich eine untere vertikale Auflagerfläche 15 an, die an der Unterseite des Bauteils 4 endet. Wie schon beim Baukörper 1, so sind auch beim Bauteil 4 die Auflagerflächen 13 bis 15 von dünnen Platten gebildet, die auf den entsprechenden Seitenflächen des Vorsprungs 12 angeordnet sind. Die Platten besitzen eine Dicke von maximal 2 mm, vorzugsweise maximal 1 mm und bestehen beispielsweise aus Polytetrafluorethylen, Polyethylen, Polyamid, Nylon, Polyethylenterephtalat oder einem Polyacetalhomopolymer. Die sich mit den Lagerflächen 8 bis 10 und Auflagerflächen 13 bis 15 einstellenden Materialpaarungen sind vorzugsweise von unterschiedlichen Materialien gebildet, beispielsweise aus Nylon und Polyethylenterephtalat oder Polyacetal und Polyamid, um eine Vernetzung der Lagerflächen 8 bis 10 mit den Auflagerflächen 13 bis 15 zu verhindern, womit eine Erhöhung der Haftreibung einher ginge. Bevorzugt sind Materialpaarungen, bei denen sich ein Haftreibungskoeffizient von weniger als 0,2, vorzugsweise von weniger als 0,1 ergibt. Um die Haftreibung zusätzlich zu vermindern, kann in der Kontaktfläche zwischen den Lagerflächen 8 bis 10 und Auflagerflächen 13 bis 15 ein Gleitfett vorgesehen sein. Auf diese Weise bildet die Kontaktfläche zwischen den Lagerflächen 8 bis 10 und Auflagerflächen 13 bis 15 eine Anschlussfuge 16, in der das Bauteil 4 Relativbewegungen in Längserstreckungsrichtung L gegenüber dem Baukörper 1 ausführen kann.The component 4 has in the region of its longitudinal side 5 in the niches 7 opposite longitudinal sections each have a projection 12 with a niche to the 7th complementary geometric formation to allow the projection 12 to enter the niche 7. The projection 12 has an outgoing from the top of the component 4 upper vertical support surface 13, which merges at about half the height of the component 4 in a horizontal support surface 14. This is followed by a lower vertical support surface 15, which ends at the bottom of the component 4. As in the case of the building 1, the support surfaces 13 to 15 are also formed in the component 4 of thin plates, which are arranged on the corresponding side surfaces of the projection 12. The plates have a thickness of at most 2 mm, preferably at most 1 mm and consist for example of polytetrafluoroethylene, polyethylene, polyamide, nylon, polyethylene terephthalate or a polyacetal homopolymer. The adjusting with the bearing surfaces 8 to 10 and bearing surfaces 13 to 15 material pairings are preferably formed of different materials, such as nylon and polyethylene terephthalate or polyacetal and polyamide to prevent cross-linking of the bearing surfaces 8 to 10 with the bearing surfaces 13 to 15, which an increase in stiction would go along. Preference is given to material pairings in which a static friction coefficient of less than 0.2, preferably less than 0.1 results. In order to additionally reduce the static friction, a lubricating grease may be provided in the contact surface between the bearing surfaces 8 to 10 and bearing surfaces 13 to 15. In this way, the contact surface between the bearing surfaces 8 to 10 and bearing surfaces 13 to 15 forms a connecting joint 16, in which the component 4 can perform relative movements in the longitudinal direction L relative to the structure 1.

Eine mögliche Herstellung des Vorsprungs 12 besteht darin, diesen im Zuge des Betonierens des Bauteils 4 monolithisch herzustellen. Eine demgegenüber bevorzugte Ausführungsform ist in den Fig. 2 und 3 vorgestellt. Dabei wird der Vorsprung 12 von einem Stahlbetonfertigteil gebildet, das vorzugsweise eine Druckfestigkeit von mehr als 65 N/mm2 aufweist und über eine Anschlussbewehrung in den Beton des übrigen Bauteils 4 einbindet. Denkbar ist auch; dass der Vorsprung 12 von einem Stahlbauteil gebildet ist.One possible production of the projection 12 is to produce it monolithically in the course of concreting the component 4. A contrast preferred embodiment is in the Fig. 2 and 3 presented. In this case, the projection 12 is formed by a precast reinforced concrete part, which preferably has a compressive strength of more than 65 N / mm 2 and binds via a connection reinforcement in the concrete of the rest of the component 4. It is also conceivable; the projection 12 is formed by a steel component.

Zur Erzeugung der notwendigen Kraft, um das Bauteil 4 gegen den Baukörper 1 vorzuspannen, sind beim vorliegenden Ausführungsbeispiel pro Kraftübertragungsbereich 6 jeweils zwei achsparallele Spannelemente 17 vorgesehen, die sich vom Bauteil 4 in den Baukörper 1 erstrecken. In Abhängigkeit der notwendigen Spannkraft können auch drei, vier oder mehr Spannelemente 17 vorgesehen sein. Die einzelnen Spannelemente 17 eines Kraftübertragungsbereichs halten dabei vorzugsweise einen gegenseitigen Abstand von 100 mm bis 150 mm ein. Jedes Spannelement 17 kann beispielsweise aus einem einzelnen Stahlstab 18 oder Litzen 30 gebildet sein und ist mit seinem einen Ende über eine auf das Ende aufgeschobene und mittels einer auf das Ende aufgeschraubten Gewindemutter 20 mit Ankerscheibe im Bauteil 4 verankert.To generate the necessary force to bias the component 4 against the structure 1, in the present embodiment, two axially parallel clamping elements 17 are provided per power transmission region 6, which extend from the component 4 into the structure 1. Depending on the necessary clamping force and three, four or more clamping elements 17 may be provided. The individual clamping elements 17 of a power transmission area preferably keep a mutual distance from 100 mm to 150 mm. Each clamping element 17 may for example be formed from a single steel rod 18 or strands 30 and is anchored at one end via a pushed onto the end and by means of a screwed onto the end threaded nut 20 with armature disk in the component 4.

Im weiteren Verlauf durchdringt das Spannelement 17 die Anschlussfuge 16 und damit die obere vertikale Lagerfläche 8 und obere vertikale Auflagerfläche 13 und führt im Weiteren mit seinem anderen Ende zu einer Aussparung 21 in der Oberseite des Baukörpers 1. Dort ist auf das freie Ende des Spannelements 17 eine Ankerplatte 23 aufgeschoben, die mittels einer Spannmutter 24 gegen eine Wand der Aussparung 21 gespannt ist und so das Bauteil 4 dauerhaft an den Baukörper 1 anschließt.In the further course penetrates the clamping element 17, the connecting joint 16 and thus the upper vertical bearing surface 8 and upper vertical bearing surface 13 and further leads at its other end to a recess 21 in the top of the building 1. There is on the free end of the clamping element 17th an anchor plate 23 is pushed, which is stretched by a clamping nut 24 against a wall of the recess 21 and so the component 4 is permanently connected to the building 1.

Wie ebenfalls Figur 2 zeigt ist der zwischen Anschlussfuge 16 und Aussparung 21 liegende Bereich des Kraftübertragungsbereichs 6 untergliedert in einen ersten Abschnitt 25, der sich von der Aussparung 21 bis etwa zur Mitte des Bereichs erstreckt und einen daran anschließenden bis zur Anschlussfuge 16 reichenden zweiten Abschnitt 27. Im ersten Abschnitt 25 ist jedes Spannelement 17 längsverschieblich innerhalb eines Kanals 26 im Baukörper 1 geführt ist. Hingegen wird der zweite Abschnitt 27 von einem nachträglichen Verguss 28 gebildet, der nach dem Montieren und Spannen der Spannelemente 17 hergestellt wird und eine von der Oberseite des Stahlbetondecke 2 ausgehende, die Spannelemente 17 aufnehmende Vertiefung 44 ausfüllt. Daraus ergibt sich der Vorteil, dass herstellungs- und montagebedingte Ungenauigkeiten, die den Verlauf der Spannelemente 17 betreffen, innerhalb des zweiten Abschnitts 27 ausgeglichen werden können.Like also FIG. 2 1, the region of the force transmission region 6 lying between connecting joint 16 and recess 21 is subdivided into a first section 25 which extends from the recess 21 to approximately the middle of the region and a second section 27 extending to the connecting joint 16 in the first section 25, each clamping element 17 is guided longitudinally displaceable within a channel 26 in the building 1. On the other hand, the second section 27 is formed by a subsequent encapsulation 28, which is produced after mounting and tensioning of the clamping elements 17 and fills a recess 44 extending from the upper side of the reinforced concrete ceiling 2 and receiving the clamping elements 17. This results in the advantage that manufacturing and assembly-related inaccuracies which relate to the course of the clamping elements 17 can be compensated within the second section 27.

Zusätzlich sind die Spannelemente 17 zumindest im zweiten Abschnitt 27, vorzugsweise auch im Bereich des Vorsprungs 12, innerhalb einer Ummantelung 29 aus verformbarem Material wie zum Beispiel einem schaumstoffartigen Material geführt. Diese konstruktive Ausbildung dient in erster Linie zum Ausgleich temperaturbedingter Längenänderungen des Bauteils 4 gegenüber dem Baukörper 1, die quer zur Längsachse der Spannelemente 17 gerichtet sind. Gleichzeitig sorgt die Ummantelung 29 jedoch auch dafür, dass kein Verbund zwischen den Spannelementen 17 und dem Verguss 28 entsteht, so dass Relativbewegungen zwischen den Spannelementen 17 und dem Baukörper 1 während des Spannens nicht behindert werden und somit die Spannkraft voll zum Anschluss des Bauteils 4 genutzt werden kann.In addition, the clamping elements 17 are guided at least in the second section 27, preferably also in the region of the projection 12, within a casing 29 made of deformable material such as a foam-like material. This structural design is used primarily to compensate for temperature-induced changes in length of the component 4 relative to the structure 1, which are directed transversely to the longitudinal axis of the clamping elements 17. At the same time, however, the sheath 29 also ensures that no bond is formed between the clamping elements 17 and the encapsulation 28, so that relative movements between the clamping elements 17 and the structure 1 during clamping are not impeded and thus the clamping force is fully utilized for the connection of the component 4 can be.

Die Fig. 4 und 5 betreffen unterschiedliche Ausführungsformen der Verankerung im Baukörper 1, bei denen Litzen 30 als Spannelemente 17 verwendet werden. Die Litzen 30 bestehen aus einem zentralen Stahldraht, den sechs weitere Stahldrähte wendelförmig umlaufen. Durch eine Fettbeschichtung der Stahldrähte sowie einer enge Kunststoffummantelung 31 sind die Stahldrähte vor Korrosion geschützt.The Fig. 4 and 5 relate to different embodiments of anchoring in the building 1, in which strands 30 are used as clamping elements 17. The strands 30 consist of a central steel wire, the six other steel wires rotate helically. By a fat coating of the steel wires and a tight plastic sheath 31, the steel wires are protected from corrosion.

In Fig. 4 sieht man den im Verankerungsbereich liegenden Teil des Baukörpers 1 mit Aussparung 21. Den Übergang vom Abschnitt 25 des Baukörpers 1 zur Aussparung 21 bildet eine Ankerplatte 19 aus Stahl. Man sieht das eine Ende des im Abschnitt 25 verlaufenden Kanals 26, innerhalb dessen die Litze 30 geführt ist. Zur Litze 30 hin ist der Kanal 26 von einem zusätzlichen Hüllrohr 32 begrenzt, das die Litze 30 mit Spiel umgibt. So kann der Kanal 26 nach Montage und Spannen der Spannelemente 17 mit einem Injektionsmörtel verfüllt werden, ohne dass sich dabei ein Verbund zur Litze 30 ergibt.In Fig. 4 one sees the lying in the anchoring area part of the building 1 with recess 21. The transition from section 25 of the building 1 to the recess 21 forms an anchor plate 19 made of steel. One sees the one end of the channel 26 extending in the section 25, within which the strand 30 is guided. Toward the strand 30, the channel 26 is delimited by an additional cladding tube 32, which surrounds the strand 30 with clearance. Thus, after installation and tensioning of the clamping elements 17, the channel 26 can be filled with an injection mortar without resulting in a bond to the strand 30.

Der Kanal 26 schließt an eine koaxiale Bohrung 33 in der Ankerplatte 19 an, durch welche jeweils eine Litze 30 mit ihrer Kunststoffummantelung 31 geführt ist, die anschließend mit ihrem freien Ende in der Aussparung 21 endet. Das freie Ende der Litze 30 ist von der Kunststoffummantelung 31 befreit, um eine Keilverankerung 34 kraftschlüssig aufbringen zu können.The channel 26 connects to a coaxial bore 33 in the anchor plate 19, through which a strand 30 is guided with its plastic sheath 31, which then ends with its free end in the recess 21. The free end of the strand 30 is freed from the plastic casing 31 in order to be able to apply a wedge anchoring 34 in a force-fitting manner.

Die Keilverankerung 34 umfasst eine Ankerhülse 35 mit einem Außengewinde 36 und einer koaxialen Durchgangsbohrung 37. Die Durchgangsbohrung 37 ist zur Aufnahme von drei segmentartigen Verankerungskeilen 38 konisch aufgeweitet. Das der Ankerplatte 19 zugewandte Ende der Durchgangsbohrung 37 weist ebenfalls eine Aufweitung zum Anschluss der Kunststoffummantelung 31 der Litze 30 auf.The wedge anchor 34 includes an anchor sleeve 35 having an external thread 36 and a coaxial through bore 37. The through bore 37 is flared to receive three segmental anchoring wedges 38. The armature plate 19 facing the end of the through hole 37 also has a widening for connecting the plastic sheath 31 of the strand 30 on.

Auf die Ankerhülse 35 ist eine Ankermutter 39 mit Innengewinde 40 aufgeschraubt und stützt sich dabei auf der Ankerplatte 19 ab. Im Zuge des Aufschraubens der Ankermutter 39 wird die Ankerhülse 35 axial in Spannrichtung bewegt, wobei die Verankerungskeile 38 innerhalb ihrer konischen Aufnahme radial gegen die Stahldrähte der Litze 30 gepresst werden. Dabei wird eine kraftschlüssige Klemmwirkung erzielt und im Weiteren ein axiales Spannen der Litze 30 bewirkt.An anchor nut 39 with internal thread 40 is screwed onto the anchor sleeve 35 and is supported on the anchor plate 19. In the course of screwing the anchor nut 39, the anchor sleeve 35 is moved axially in the clamping direction, wherein the anchoring wedges 38 are pressed radially within their conical receiving against the steel wires of the strand 30. In this case, a non-positive clamping effect is achieved and causes an axial clamping of the strand 30 in addition.

Das stirnseitige Ende der Keilverankerung 34 bildet eine Kappe 41, die auf die Ankerhülse 35 aufgeschraubt ist. Eine Fettfüllung innerhalb der Keilverankerung 34 sorgt für einen Korrosionsschutz der Litze 30 in dem Längsabschnitt ohne Kunststoffummantelung 31.The front end of the wedge anchor 34 forms a cap 41 which is screwed onto the anchor sleeve 35. A grease filling within the wedge anchor 34 provides corrosion protection of the strand 30 in the longitudinal section without plastic sheath 31.

Fig. 5 unterscheidet sich hiervon lediglich durch eine funktional aufgelöste Ausbildung der Keilverankerung 34'. In Fig. 5 weist die Ankerhülse 35' eine Durchgangsbohrung 37' auf, die lediglich zur Durchleitung der Litze 30 dient, nicht aber zu deren Verankerung. Die Verankerung erfolgt in einem sich auf der Ankerhülse 35' abstützenden Ankerelement 42 mit fluchtender Durchgangsbohrung 43, die sich zum freien Ende hin konisch aufweitet und dadurch eine Aufnahme für die Verankerungskeile 38 bildet. Somit bilden in funktionaler Hinsicht die Ankerhülse 35' zum Spannen des Spannelements 17 und das Ankerelement 42 zum Verankern der Litze 30 jeweils eine gesonderte Funktionskomponente. Fig. 5 differs from this only by a functionally resolved training of the wedge anchor 34 '. In Fig. 5 the anchor sleeve 35 'on a through hole 37', which serves only for the passage of the wire 30, but not to the anchorage. The anchoring takes place in an armature sleeve 35 'supporting armature element 42 with aligned through hole 43, which widens conically towards the free end and thereby forms a receptacle for the anchoring wedges 38. Thus, in functional terms, the anchor sleeve 35 'for tensioning the tension element 17 and the anchor element 42 for anchoring the strand 30 each form a separate functional component.

Die Fig. 6 und 7 zeigen eine weitere Ausführungsform der Erfindung. Diese Ausführungsform entspricht in weiten Teilen der unter den Fig. 1 bis 5 beschriebenen, so dass für gleiche oder funktionsgleiche Merkmale gleiche Bezugszeichen Verwendung finden und das unter den Fig. 1 bis 5 Gesagte entsprechend gilt.The Fig. 6 and 7 show a further embodiment of the invention. This embodiment corresponds in many parts of the Fig. 1 to 5 described, so that the same or functionally identical features the same reference numerals are used and that under the Fig. 1 to 5 Said accordingly applies.

Ein Unterschied betrifft die konstruktive Ausbildung der Anschlussfuge 16, die in Fig. 6 in größerem Maßstab dargestellt ist. Die Anschlussfuge 16 gemäß der weiteren Ausführungsform wird von einem Lagermodul 46 gebildet, das die Lagerflächen 8, 9, 10 und Auflagerflächen 13, 14 und 15 in sich vereint. Zu diesem Zweck weist das Lagermodul 46 ein erstes Stahlblech 47 auf, das zweimal in entgegen gesetzter Richtung abgewinkelt ist und somit der Form der Anschlussfuge 16 folgt. Weiter umfasst das Lagermodul 46 ein zweites Stahlblech 48, das in etwa die gleiche Form wie das erste Stahlblech 47 besitzt und planparallel zu diesem angeordnet ist.One difference relates to the structural design of the connection joint 16, which in Fig. 6 is shown on a larger scale. The connecting joint 16 according to the further embodiment is formed by a bearing module 46, which combines the bearing surfaces 8, 9, 10 and bearing surfaces 13, 14 and 15 in itself. For this purpose, the bearing module 46 has a first steel sheet 47, which is angled twice in the opposite direction and thus follows the shape of the connecting joint 16. Further, the storage module 46 comprises a second steel sheet 48, which has approximately the same shape as the first steel sheet 47 and is arranged plane-parallel to this.

Zwischen den beiden Stahlblechen 47 und 48 sind eine erste Lagerplatte 49 und eine zweite Lagerplatte 50 angeordnet, die sich über die gesamte Fläche der Stahlbleche 47 und 48 erstrecken. Die Lagerplatten 49 und 50 bestehen aus Materialien mit einem Haftreibungskoeffizienten von weniger als 0,2, vorzugsweise weniger als 0,1, beispielsweise aus Polytetrafluorethylen, Polyethylen, Polyamid, Nylon, Polyethylenterephtalat oder Polyacetal, wobei innerhalb eines Lagermoduls 46 die Kombination zweiter unterschiedlicher Materialien bevorzugt ist, also die Lagerplatte 49 aus einem anderen Material besteht wie die Lagerpatte 50. Die Gleitfuge bei unterschiedlichen Bewegungen von Baukörper 1 und Bauteil 4 liegt somit zwischen den beiden Lagerplatten 49 und 50.
Der Rand des Lagermoduls 46 ist von einem umlaufenden elastischen Dichtungsprofil 51 bedeckt, das die Stahlbleche 47 und 48 mit den darin eingeschlossenen Lagerplatten 49 und 50 gleichzeitig zusammenhält. In Längsrichtung, also senkrecht zur Darstellungsebene, erstreckt sich das beschriebene Lagermodul 46 über die gesamte Länge des Vorsprungs 12.Between the two steel sheets 47 and 48, a first bearing plate 49 and a second bearing plate 50 are arranged, which extend over the entire surface of the steel sheets 47 and 48. The bearing plates 49 and 50 are made of materials having a coefficient of static friction of less than 0.2, preferably less than 0.1, for example polytetrafluoroethylene, polyethylene, polyamide, nylon, polyethylene terephthalate or polyacetal, wherein within a bearing module 46 the combination of second different materials is preferred is, so the bearing plate 49th made of a different material than the bearing plate 50. The sliding joint with different movements of the structure 1 and component 4 is thus between the two bearing plates 49 and 50th
The edge of the bearing module 46 is covered by a circumferential elastic sealing profile 51, which simultaneously holds the steel sheets 47 and 48 with the bearing plates 49 and 50 enclosed therein. In the longitudinal direction, ie perpendicular to the plane of representation, the bearing module 46 described extends over the entire length of the projection 12.

Ein derartiges Lagermodul 46 kann beispielsweise bei der Herstellung der Vorsprünge 12 als Einbauteil in die Schalung gestellt werden oder selbst Teil der Schalung sei, so dass nach dem Einfüllen und Abbinden des Betons eine starre Verbindung zwischen Lagermodul 46 und Vorsprung 12 entsteht. Bei der Herstellung des Vergusses 28 auf Seiten des Baukörpers 1 bildet das Lagermodul 46 wiederum die Stirnabschalung, so dass der Verguss 28 direkt gegen das Lagermodul 46 erfolgt. Dadurch ist ein optimaler Kraftschluss zwischen dem Bauteil 4 und dem Baukörper 1 gewährleistet und es werden die Montagearbeiten vereinfacht und verkürzt.
Ein weiterer Unterschied der unter den Fig. 5 und 6 beschriebenen Ausführungsform besteht darin, dass der vor der Verankerung im Baukörper 1 liegende Abschnitt 25 nicht vom Ortbeton des Baukörpers gebildet ist, sondern aus einem Fertigteil 52 besteht, das vorzugsweise aus einem Beton höherer Qualität hergestellt ist, beispielsweise aus einem Beton mit einer Festigkeit von 65 N/mm2 oder mehr. In ein solches Fertigteil 52 kann bereits bei dessen Herstellung eine Ankerplatte 19 integriert werden, so dass die Einheit aus Fertigteil 52 und Ankerplatte 19 vor dem Betonieren des Baukörpers 1 lediglich noch in der vorbestimmten Lage fixiert werden muss, bevor der Baukörper 1 betoniert wird.
Es versteht sich, dass die Erfindung nicht auf die einzelnen Merkmalskombinationen vorliegender Ausführungsbeispiele beschränkt ist, sondern ebenfalls Merkmalskombinationen unterschiedlicher Ausführungsbeispiele mit umfasst, soweit sie von den Ansprüchen abgedeckt sind.Such a storage module 46 can be made for example in the production of the projections 12 as a built-in part in the formwork or even be part of the formwork, so that after filling and setting of the concrete a rigid connection between the storage module 46 and projection 12 is formed. In the production of the encapsulation 28 on the side of the building 1, the storage module 46 again forms the front shutter, so that the encapsulation 28 takes place directly against the storage module 46. As a result, an optimal frictional connection between the component 4 and the structure 1 is ensured and the assembly work is simplified and shortened.
Another difference among the Fig. 5 and 6 described embodiment is that the lying in front of the anchorage in the building 1 section 25 is not formed of in-situ concrete of the building, but consists of a finished part 52, which is preferably made of a higher quality concrete, for example, a concrete with a strength of 65 N / mm 2 or more. An anchor plate 19 can already be integrated into such a finished part 52 during its production, so that the unit made of finished part 52 and anchor plate 19 only has to be fixed in the predetermined position before concreting the structure 1 before the building 1 is concreted.
It is understood that the invention is not limited to the individual feature combinations of the present embodiments, but also includes feature combinations of different embodiments, as far as they are covered by the claims.
