Description

Die vorliegende Erfindung betrifft ein Verfahren zum risssicheren, dichten Anschluss eines Asphaltbelages an einen Bauteil, insbesondere Betonteil. Solche Anschlüsse sind erforderlich bei Betonbrücken, und zwar sowohl an den Rändern der Fahrbahn als auch an den Rändern von Gehsteigen, bei Flachdächern u.dgl. Die zu diesem Zwecke übliche Fugenverkittung erweist sich als ungenügend, denn infolge des starken Schwindens des Asphaltbelages entstehen bereits bei Abkühlung unter etwa 140°C, jedenfalls aber später, bei sehr tiefen Temperaturen Risse, die früher oder später zur Beschädigung des Asphaltbelages und/oder des Bauteils in der Umgebung der Fuge führen.The present invention relates to a method for crack-proof, tight connection of an asphalt surface to a component, in particular a concrete part. Such connections are required for concrete bridges, both on the edges of the road and on the edges of sidewalks, flat roofs and the like. The joint cementation that is customary for this purpose proves to be inadequate, because due to the strong shrinkage of the asphalt surface, cracks occur sooner or later, at very low temperatures, which sooner or later damage the asphalt surface and / or the Guide the component in the vicinity of the joint.

Die genannten Nachteile können nicht vermieden werden, wenn in bekannter Weise längs der Fuge zwischen dem Asphaltbelag und dem Betonbauteil eine sich nach unten verjüngende Nut gefräst und diese mit einem bituminösen Kautschuk vergossen wird (CH-A-373 777).The disadvantages mentioned cannot be avoided if, in a known manner, a groove tapering downwards is milled along the joint between the asphalt surface and the concrete component and this is cast with a bituminous rubber (CH-A-373 777).

Es ist auch bekannt, vor dem Einbringen des Asphaltes am Bauwerk ein Fugenband anzubringen (DE-A-1 965 092). Auch dieses Vorgehen hat sich als ungenügend erwiesen, um allen Anforderungen gerecht zu werden.It is also known to apply a joint tape to the structure before placing the asphalt (DE-A-1 965 092). This approach has also proven to be insufficient to meet all requirements.

Versuche haben nämlich gezeigt, dass zur Erzielung eines dauerhaften, risssicheren und dichten Anschlusses eines Asphaltbelages an einen starren Bauteil, insbesondere Betonteil, ganz bestimmte Voraussetzungen zu erfüllen sind, d. h. dass während des Einbringens und Erstarrens des Betons in bestimmter Weise vorzugehen ist, um alle Vorbedingungen zu erfüllen, damit weder während des Einbringens und Erstarrens des Asphalts noch später bei den grossen zu erwartenden Temperaturunterschieden trotz seiner geringen Zugfestigkeit, seines starken Schwindens beim Erstarren und seiner Plastizität und seines hohen Ausdehnungskoeffizienten Risse und in ihrer Folge grössere Schäden auftreten.Experiments have shown that in order to achieve a permanent, crack-proof and leak-proof connection of an asphalt surface to a rigid component, in particular a concrete part, certain conditions must be met, i. H. that during the pouring and solidification of the concrete, a certain procedure has to be carried out in order to meet all preconditions, so that neither during the pouring and solidification of the asphalt nor later with the large temperature differences to be expected despite its low tensile strength, its strong shrinkage during solidification and its plasticity and its high coefficient of expansion cracks and, as a result, greater damage occur.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren anzugeben, welches den vorerwähnten komplexen Anforderungen genügt und Rissbildungen, sei es durch Reissen des Asphalts oder Ablösen der Fugendichtung vom Asphalt oder vom Bauwerk, sicher und dauernd zu vermeiden gestattet.The invention has for its object to provide a method that meets the aforementioned complex requirements and allows cracking, be it by tearing the asphalt or detaching the joint seal from the asphalt or from the building, safely and permanently avoided.

Diese Aufgabe wird dadurch gelöst, dass am Bauteil ein Anschlussprofil angelegt wird, das den Asphalt beim Aufbringen des Asphaltbelages mindestens im oberen Teil vom Bauwerk trennt, und dass das Anschlussprofil nach mindestens teilweisem Erstarren des Asphaltbelages gespreizt wird.This object is achieved in that a connection profile is created on the component that separates the asphalt from the structure at least in the upper part when the asphalt surface is applied, and that the connection profile is spread after the asphalt surface has at least partially solidified.

Es genügt somit nicht, irgendein Dichtungsband Pin7t.Jipn.en oder eine Dichtungsmasse in die Fuge einzubringen, sondern es ist ein Anschlussprofil vorzusehen, welches ohne erhebliche Verformungskräfte dem Asphaltbelag bei seinem Erstarren folgen kann, und das dann zusätzlich gespreizt wird, und zwar erst wenn der Asphalt soweit verfestigt ist, dass er durch den Spreizdruck nicht verformt wird.It is therefore not sufficient to insert any Pin7t.Jipn.en sealing tape or a sealing compound into the joint, but to provide a connection profile that can follow the asphalt surface when it solidifies without considerable deformation forces, and which is then additionally spread, and only when the asphalt is solidified to such an extent that it is not deformed by the spreading pressure.

Vorzugsweise wird ein gekammertes Anschlussprofil hoher Elastizität und/oder ein gekammertes Spreizprofil zum Spreizen desselben verwendet, um in allen Phasen eine hohe Deformierbarkeit des Anschlussprofils zu erzielen.A chambered connection profile of high elasticity and / or a chambered expansion profile is preferably used for spreading the same, in order to achieve high deformability of the connection profile in all phases.

Es ist zwar aus der DE-A-2 249 879 bekannt, eine V-förmige Scheidenprofilleiste in einen noch nicht erhärteten Estrich, also nicht in Asphalt, längs einer Betonwand einzudrücken und dann in die Scheidenprofilleiste eine gegebenenfalls keilförmig ausgebildete Füllprofilleiste einzusetzen. Ein Spreizen der Scheidenprofilleiste ist jedoch nicht vorgesehen, und das bekannte Verfahren ist daher weder zum rissfreien Erstellen eines Asphaltbelages geeignet, noch konnte es ein hierfür optimales Vorgehen anregen.It is known from DE-A-2 249 879 to press a V-shaped vaginal profile strip into a not yet hardened screed, i.e. not in asphalt, along a concrete wall and then to insert an optionally wedge-shaped fill profile strip into the vaginal profile strip. Spreading of the scabbard profile strip is not provided, however, and the known method is therefore not suitable for crack-free creation of an asphalt surface, nor was it able to suggest an optimal procedure for this.

Die Erfindung betrifft auch einen Satz von Profilen zur Durchführung des oben erläuterten Verfahrens, mit spreizbarem Anschlussprofil und in dasselbe steckbarem Spreizprofil, z. B. Keilband.The invention also relates to a set of profiles for carrying out the method explained above, with an expandable connection profile and in the same plug-in expansion profile, for. B. Wedge belt.

Die Erfindung betrifft schliesslich auch eine Baukonstruktion mit einem Asphaltbelag, wobei an der Anschlussstelle des Asphaltbelages am Bauteil, insbesondere Betonbauteil der Baukonstruktion ein Anschlussprofil eingelegt ist, in das ein Spreizprofil eingesetzt ist.Finally, the invention also relates to a construction with an asphalt covering, a connection profile being inserted into the expansion joint at the connection point of the asphalt covering on the component, in particular the concrete component of the construction construction.

Die Erfindung wird nun anhand der Zeichnung näher erläutert, die ein Ausführungsbeispiel zeigt.

The invention will now be explained in more detail with reference to the drawing, which shows an embodiment.
  • 1 shows a cross section through the relevant part of the structure immediately after the asphalt has been poured,
  • 2 shows a spreading profile,
  • Fig. 3 shows an application example of the invention, and
  • 4 shows an embodiment variant.

Fig. 1 zeigt einen Betonbauteil 1, beispielsweise die Fahrbahn einer Brücke, auf dessen Boden 2 ein Asphaltbelag 3 aufzubringen ist. Gegen die seitliche Begrenzungswand 4 wird unten ein Trennprofil 5, beispielsweise aus Neopren, angelegt. Dieses Trennprofil besteht aus einzelnen Kammerprofilen unterschiedlicher Höhe, die einseitig mit T-förmigen Verankerungsrippen 6 versehen sind, während die gegenüberliegende Seite flach ausgebildet ist. Die flachen Seiten sind mittels eines geeigneten Klebers, beispielsweise Neopren-Kleber mit dem Beton verklebt. Die Trennprofile werden bandförmig in einer bestimmten Breite hergestellt, wobei immer abwechslungsweise ein höheres und ein niedrigeres Kastenprofil aufeinander folgen, derart, dass Profile geeigneter Höhe längs den schwächsten Stellen 7 von den Bändern abgerissen werden können. Im vorliegenden Falle sind nur zwei Kastenprofile erforderlich.1 shows a concrete component 1, for example the roadway of a bridge, on the floor 2 of which an asphalt covering 3 is to be applied. A separating profile 5, for example made of neoprene, is placed against the lateral boundary wall 4 below. This separating profile consists of individual chamber profiles of different heights, which are provided on one side with T-shaped anchoring ribs 6, while the opposite side is flat. The flat sides are glued to the concrete using a suitable adhesive, for example neoprene adhesive. The separating profiles are produced in the form of a tape in a certain width, with a higher and a lower box profile alternating in succession in such a way that profiles of a suitable height can be torn off the tapes along the weakest points 7. In the present case, only two box profiles are required.

Über dem Trennprofil 5 ist ein V-förmiges Anschlussprofil 8 mit gekammerten Schenkeln angeordnet. Die eine flache Seite dieses Profils, das ebenfalls aus Neopren bestehen kann, ist mittels Neopren-Kleber mit der Seitenwand 4 des Betonteils 1 verklebt. An der gegenüberliegenden Seite ist auch dieses Anschlussprofil mit T-förmigen Verankerungsrippen 6 versehen. Der keilförmige Zwischenraum zwischen den beiden Schenkeln des Profils 8 ist mit einem bandförmigen Streifen 9 abgeschlossen, der an den schwachen Verbindungsstellen 10 mit den Profilschenkeln leicht abgerissen werden kann. Das Anschlussprofil 8 weist an der dem Betonteil 1 zugewandten Seite eine hochstehende Lippe 11 auf.A V-shaped connection profile 8 with chambered legs is arranged above the separating profile 5. One flat side of this profile, which can also consist of neoprene, is attached to the side wall 4 of the concrete by means of neoprene adhesive partly 1 glued. On the opposite side, this connection profile is also provided with T-shaped anchoring ribs 6. The wedge-shaped space between the two legs of the profile 8 is closed with a band-shaped strip 9, which can be easily torn off at the weak connection points 10 with the profile legs. The connection profile 8 has a raised lip 11 on the side facing the concrete part 1.

Sind die Profile 5 und 8 gemäss Fig. 1 an der Seitenwand des Betonteils 1 angebracht, wird der Asphaltbelag 3 gegossen, wobei dank den Verankerungsrippen 6 eine zugfeste Verbindung zwischen den Profilen 5 und 8 einerseits und dem Asphaltbelag anderseits entsteht. Die Fuge zwischen dem Trennprofil 5 und dem Anschlussprofil 8 braucht nicht geklebt zu sein, sondern es genügt, wenn diese Profile so eng aufeinander liegen, dass der Asphalt nicht dazwischen bis an den Bauteil 1 durchdringen kann. Ist der Asphaltbelag mindestens teilweise erstarrt, wird der Profilstreifen 9 aus dem Profil ausgerissen und an seiner Stelle wird das keilförmige Spreizprofil 12 gemäss Fig. 2 zwischen die Schenkel des Profils 8 eingepresst und damit dieses Profil gespreizt und elastisch zusammengedrückt. Zugleich entsteht oben ein dichter Abschluss des Spaltes im Profil 8. Die komplementäre Zahnung an der Innenseite der Schenkel des Profils 8 einerseits und an der Aussenseite des Spreizprofils 12 gemäss Fig. anderseits gewährleistet einen tadellosen Halt des Spreizprofils 12 im Anschlussprofil 8. Im fertiggestellten Bauwerk mit vollständig ausgekühltem Asphaltbelag 3 ist somit das Anschlussprofil 8 immer noch elastisch komprimiert und kann somit bei weiterem Schwinden des Asphaltbelages bei sehr tiefen Temperaturen nicht von diesem Belag oder vom Betonteil 1 losgerissen werden. Es ist auch bei extrem tiefen Temperaturen nicht möglich, dass der Spreizkeil 12 nach Fig. 2 im Profil sich lockert und Wasser oder Verunreinigung zwischen sich und dem Profil 8 eindringen lässt. Die am Betonteil 4 hochgeführte Lippe 11 verhindert, dass sich im Bereiche der Fuge am Betonteil Moos und Verunreinigungen ansetzen.If the profiles 5 and 8 according to FIG. 1 are attached to the side wall of the concrete part 1, the asphalt covering 3 is poured, and thanks to the anchoring ribs 6, a tensile connection is created between the profiles 5 and 8 on the one hand and the asphalt covering on the other. The joint between the separating profile 5 and the connecting profile 8 does not need to be glued, but it is sufficient if these profiles are so close to one another that the asphalt cannot penetrate to the component 1 in between. If the asphalt surface is at least partially solidified, the profile strip 9 is torn out of the profile and in its place the wedge-shaped expansion profile 12 according to FIG. 2 is pressed between the legs of the profile 8 and thus this profile is spread and compressed elastically. At the same time, the gap in the profile 8 is sealed at the top. The complementary toothing on the inside of the legs of the profile 8 on the one hand and on the outside of the expansion profile 12 as shown in FIG completely cooled asphalt surface 3, the connection profile 8 is still elastically compressed and cannot be torn off this surface or the concrete part 1 if the asphalt surface continues to shrink at very low temperatures. Even at extremely low temperatures it is not possible for the expansion wedge 12 according to FIG. 2 to loosen in the profile and for water or contamination to penetrate between it and the profile 8. The lip 11 raised on the concrete part 4 prevents moss and impurities from accumulating in the area of the joint on the concrete part.

Es genügt, dass im fertiggestellten Bauwerk das Anschlussprofil 8 dicht mit dem Betonteil 1 und dem Asphaltbelag 3 verbunden bleibt, sodass keinerlei Verunreinigung oder Wasser eindringen kann. Das Trennprofil 5 dient dagegen lediglich dazu, den Asphaltbelag beim Giessen von der Seitenwand 4 des Betonteils 1 getrennt zu halten. Dieses Profil kann beim Schwinden des Asphaltbelages vom Betonteil 1 abgerissen werden.It is sufficient that the connection profile 8 remains tightly connected to the concrete part 1 and the asphalt covering 3 in the finished building, so that no contamination or water can penetrate. The separating profile 5, on the other hand, only serves to keep the asphalt surface separated from the side wall 4 of the concrete part 1 during casting. This profile can be torn off from the concrete part 1 when the asphalt surface shrinks.

Es sind Ausführungsvarianten möglich. So kann die dem Asphaltbelag zugewandte Seite der Profile 5 und 8 mit Bitumenlack behandelt werden, was beim Giessen des Asphaltbelages eine noch bessere Verbindung dieser Profile mit dem Asphalt ergibt. Im fertiggestellten Bauwerk wird aber die Dichtung zwischen dem Anschlussprofil 8 und dem Asphalt in jedem Falle durch mechanischen Andruck dieses Profiles infolge seiner Spreizung sichergestellt.Variants are possible. The side of profiles 5 and 8 facing the asphalt surface can be treated with bitumen varnish, which results in an even better connection of these profiles with the asphalt when pouring the asphalt surface. In the finished building, however, the seal between the connection profile 8 and the asphalt is ensured in any case by mechanical pressure of this profile due to its expansion.

Anstelle gekammerter Profile können auch Vollprofile aus Schaumkunststoff verwendet werden, doch weisen die gekammerten Profile bessere Alterungsbeständigkeit auf.Instead of chambered profiles, solid profiles made of foam plastic can also be used, but the chambered profiles have better aging resistance.

Als weitere Ausführungsvariante könnte ein V-förmiges Abschlussprofil mit dünneren, nicht gekammerten Schenkeln verwendet werden, in welches ein breiteres zur Erhöhung der Elastizität gekammertes Keilprofil eingepresst werden kann. Es wäre schliesslich auch möglich, anstelle des ausreissbaren Profilstreifens 9 eine abschliessende Wand über dem Spalt des Anschlussprofils 8 vorzusehen, welche Wand zum Einpressen des Spreizprofils aufgeschnitten werden kann.As a further embodiment variant, a V-shaped end profile with thinner, non-chambered legs could be used, into which a wider wedge profile that is chambered to increase the elasticity can be pressed. Finally, it would also be possible to provide a final wall over the gap of the connection profile 8 instead of the tear-out profile strip 9, which wall can be cut open for pressing in the expansion profile.

Fig. 3 zeigt ein Anwendungsbeispiel mit mehreren Fugen, in welchen Anschlussprofile 8 verwendet werden. Der tragende Betonteil 13 einer Brücke ist mit einer Isolation 14 belegt. Auf dem Fahrbahnteil der Brücke sind zwei Asphaltschichten 15 und 16 aufgebracht. Auf dem unteren Asphaltbelag 15 liegen die Randsteine 17, zwischen welchen und dem oberen Asphaltbelag 16 ein Anschlussprofil 8 eingelegt ist. Ausserhalb der Randsteine 17 befindet sich ein Gehsteig mit einer Asphaltschicht 18. Zwischen dieser Asphaltschicht und den Randsteinen 17 einerseits und einem äusseren Abschlussprofil 19 anderseits ist wiederum je ein Anschlussprofil 8 eingelegt.Fig. 3 shows an application example with several joints, in which connection profiles 8 are used. The load-bearing concrete part 13 of a bridge is covered with insulation 14. Two asphalt layers 15 and 16 are applied to the roadway part of the bridge. On the lower asphalt surface 15 are the curbs 17, between which and the upper asphalt surface 16 a connecting profile 8 is inserted. Outside the curbs 17 there is a sidewalk with an asphalt layer 18. Between this asphalt layer and the curbs 17 on the one hand and an outer end profile 19 on the other hand, a connecting profile 8 is in turn inserted.

Fig. 4 zeigt eine Ausführungsvariante eines Profils, wobei entsprechende Teile gleich bezeichnet sind wie in Fig. 1. Anstelle der T-förmigen Verankerungsrippen sind etwas weiter auseinanderliegende Verankerungsrippen mit Köpfen 6' kreisrunden Querschnitts vorgesehen. Es hat sich gezeigt, dass der Asphalt beim Guss besser zwischen derartige Verankerungsrippen eindringt und eine bessere Verankerung erzielt wird.FIG. 4 shows an embodiment variant of a profile, with corresponding parts being identified in the same way as in FIG. 1. Instead of the T-shaped anchoring ribs, anchoring ribs with heads 6 ′ of circular cross section that are somewhat further apart are provided. It has been shown that the asphalt penetrates better between such anchoring ribs during casting and better anchoring is achieved.

Ausserdem ist ein Trennprofil 5 über eine Rippe 20 mit dem Anschlussprofil 8 verbunden. Es hat sich gezeigt, dass ein solches Gesamtprofil für die meisten Anwendungsfälle unverändert verwendbar ist. Gegebenenfalls kann aber das Trennprofil 5 vom Anschlussprofil getrennt werden und/oder es können zusätzliche Anschlussprofile gemäss Fig. 1 verwendet werden.In addition, a separating profile 5 is connected to the connecting profile 8 via a rib 20. It has been shown that such an overall profile can be used unchanged for most applications. If necessary, however, the separation profile 5 can be separated from the connection profile and / or additional connection profiles according to FIG. 1 can be used.
