Description

Gegenstand der Erfindung ist eine Vorrichtung zum Erstellen einer Teilabschalung und/oder einer Dehnungsfugen-Abschalung an einem Betonbauwerk gemäss Oberbegriff des Patentanspruchs 1.The invention relates to a device for producing a Teilabschalung and / or a Dehnungsfugen Abschalung on a concrete structure according to the preamble of patent claim 1.

Beim Erstellen grösserer zusammenhängender Betonelemente bzw. Teile wie Decken, Böden in Gebäuden oder Wände von z.B. Tunnelröhren ist es oft nicht möglich, das gesamte Element- bzw. Betonbauteil oder -werkteil in einem Zug zu fertigen. Das Betonbauteil muss dann in mehreren Etappen gegossen werden, wobei jeweils nur einzelne Teilbereiche erstellt werden. In der Regel ist es erforderlich, dass die Bewehrungen benachbarter Teilbereiche oder Teilbauwerke sich mindestens teilweise überlappen oder weitergeführt werden, damit die Anforderungen an die Statik des gesamten Betonteils erfüllt bzw. erhalten werden können.When creating larger contiguous concrete elements or parts such as ceilings, floors in buildings or walls of eg tunnel tubes, it is often not possible to manufacture the entire element or concrete component or workpiece part in one go. The concrete component then has to be poured in several stages, whereby only individual partial areas are created. In general, it is necessary that the reinforcements of adjacent sub-areas or sub-structures overlap at least partially or be continued, so that the requirements for the statics of the entire concrete part can be met or maintained.

Aus dem Stand der Technik, Z.B. aus der EP 1 947 256 , ist eine Abschalplatte für Zwischenabschalungen bekannt, bei der Schwachstellen ausgebildet sind, die ein werkzeugfreies Hindurchstossen von Armierungseisen ermöglichen, jedoch das Hindurchfliessen der flüssigen Betonmasse genügend verhindern. Mit solchen speziellen Abschalplatten für das Betonieren von Teilbereichen ist eine sichere Verbindung zum nachträglich betonierten benachbarten Teilbereich möglich.From the prior art, for example, from the EP 1 947 256 , A Abschalplatte for Zwischenabschalungen is known in which weak points are formed, which allow a tool-free pushing through of reinforcing iron, but sufficiently prevent the passage of the liquid concrete mass. With such special Abschalplatten for concreting of subareas a secure connection to the subsequently concreted adjacent subarea is possible.

Bei der Erstellung von Betonbauwerken aus mehreren Teilbereichen, z.B. für Kellerböden, Wasserbecken in Kläranlagen oder in Frischwasserbecken oder auch Tunnelröhren besteht die latente Gefahr, dass an den Stossstellen der nacheinander betonierten Teilbauwerke Wasser entlang der Zwischenabschalungen später die Betonplatte durchdringen kann. Um dies zu vermeiden, ist es bekannt, Folien aus Gummi oder Kunststoff oder allenfalls aus Metall im Bereich der Stossstellen der Teilbereiche zwischen die Armierungen einzulegen, um den Durchtritt von Wasser an den Stosstellen der Teilbereiche zu verhindern. Das Einlegen gestaltet sich sehr aufwendig und, da die Folie vorerst nur hälftig in das erste Teilbauwerk eingegossen wird, muss bei Giessen der zweiten Teilbaute darauf geachtet werden, dass die Folie wiederum im wesentlichen rechtwinklig zur Trennstelle liegt. Dies wird häufig unsorgfältig ausgeführt und damit der Durchtritt von Wasser nicht oder nur ungenügend verhindert.In the construction of concrete structures from several areas, eg for basement floors, basins in sewage treatment plants or in fresh water pools or tunnels, there is the latent danger that at the joints of successively concreted substructures water along the Zwischenabschalungen can later penetrate the concrete slab. To avoid this, it is known to insert films made of rubber or plastic or possibly metal in the region of the joints of the subregions between the reinforcements in order to prevent the passage of water at the Stosstellen the subregions. The insertion is very complicated and, since the film is initially only half poured into the first sub-structure, care must be taken when casting the second part of construction that the film is again substantially perpendicular to the separation point. This is often carried out carelessly and thus the passage of water is not or only insufficient prevented.

Das gleiche Problem tritt auch beim Erstellen von Dehnungsfugen-Abschalungen auf. Um beim Giessen grossflächiger Betonbereiche Schwund oder Dehnungsrisse zu vermeiden, werden in aus der Erfahrung bekannten Abständen elastische Dehnungsmittel zwischen aneinanderstossende Teilbereiche eingelegt. Auch hier können bei Betonplatten, welche einseitig mit Wasser beaufschlagt werden (Tunneldecken, Ab- und Frischwasserbecken etc.), Probleme durch Wasserdurchtritt an den Dehnungsfugen auftreten.The same problem also occurs when creating expansion joint shutters. In order to avoid shrinkage or expansion cracks when casting large-area concrete areas, elastic expansion means are inserted between adjoining partial areas at intervals known from experience. Again, in concrete slabs, which are unilaterally charged with water (tunnel ceilings, wastewater and fresh water tanks, etc.), problems occur due to water leakage at the expansion joints.

Eine Aufgabe der vorliegenden Erfindung besteht nun darin, eine Vorrichtung zum Erstellen einer Teilabschalung und/oder einer Dehnungsfugen-Abschalung an einem Betonbauwerk zu schaffen, bei der das Einlegen einer Wasserbarriere oder -dichtung auf einfache, sichere und kostengünstige Weise erfolgen kann.An object of the present invention is now to provide an apparatus for creating a Teilabschalung and / or a expansion joint Abschalung on a concrete structure, in which the insertion of a water barrier or seal can be done in a simple, safe and cost-effective manner.

Gelöst wird diese Aufgabe durch eine Vorrichtung gemäss den Merkmalen des Patentanspruchs 1. Vorteilhafte Ausgestaltungen der Vorrichtung sind in den abhängigen Ansprüchen näher umschrieben.This object is achieved by a device according to the features of claim 1. Advantageous embodiments of the device are described in more detail in the dependent claims.

Die erfindungsgemässe Vorrichtung erlaubt es, bereits beim Verlegen der Armierungen und Einlegen einer Teilabschalung und/oder beim Erstellen einer Dehnungsfugen-Abschalung eine Dichtungsfolie oder -platte präzise und gegen Verschiebung geschützt während des Giessens der beiden Teilbauwerke einzulegen und festzuhalten. Das Einlegen Dichtungsfolie/Fugenabdichtung kann auch durch ungeübte Personen, wie Hilfskräfte, ohne weiteres sicher erfolgen. Der kostenmässige Aufwand für die Vorrichtung ist sehr gering und wird durch die Einsparung an Arbeitszeit und durch die Sicherheit für die spätere Wasserdichtigkeit mehr als kompensiert.The device according to the invention makes it possible to apply a sealing foil or plate precisely and against even when laying the reinforcements and inserting a partial shuttering and / or when creating a expansion joint shuttering Shift protected protected during the casting of the two sub-structures insert and hold. Inserting sealing foil / joint sealing can also be carried out safely by inexperienced persons, such as assistants. The cost of the device is very low and is more than compensated by the savings in working hours and the safety of the later waterproofness.

In der schematischen Darstellung einer Betondecke 1 in Figur 1 ist auf der rechten Seite das erste Teilbauwerk 3 und auf der linken Seite das zweite Teilbauwerk 5 ersichtlich. Dazwischen liegt eine Abschalplatte 7, umfassend ein unteres Plattenelement 7a und ein oberes Plattenelement 7b. Die beiden Plattenelemente 7a,7b sind streifenförmig ausgebildet und weisen durchbrechbare Schwachstellen 9 zum Hindurchführen von Armierungseisen 11 auf. Zwischen den beiden Plattenelementen 7a,7b sind Trägerelemente 13a und 13b angeordnet. Die Trägerelemente 13a,13b sind, wie in den Figuren 3 und 4 vergrössert dargestellt, in einer ersten Ausgestaltung der Erfindung Platten 15 aus Kunststoff, Zementbaustoff oder Metall, an denen in der Mitte und parallel zu den Längskanten verlaufend zwei Stege 17 als Halteelemente ausgebildet sind. Der Abstand D der beiden Stege 17 ist etwas grösser als die Dicke d der Plattenelemente 7a,7b. Anstelle von Stegen 17 könnten auch in einer Linie angeordnete Zapfen oder dergleichen vorgesehen sein. Ein Trägerelement 13a kann auf diese Weise auf die Oberkante der unteren Abschalplatte 7b, welche zuvor bei Verlegen der Armierung versetzt worden ist, aufgelegt werden. Das Trägerelement 13a bildet nun eine stabile, ebene Auflagefläche für eine streifenförmige Dichtfolie 19.In the schematic representation of a concrete ceiling 1 in FIG. 1 is the first substructure 3 on the right side and the second substructure 5 can be seen on the left side. In between is a Abschalplatte 7, comprising a lower plate member 7a and an upper plate member 7b. The two plate elements 7a, 7b are strip-shaped and have breakable weak points 9 for the passage of reinforcing bars 11. Support elements 13a and 13b are arranged between the two plate elements 7a, 7b. The carrier elements 13a, 13b are, as in the FIGS. 3 and 4 shown enlarged, in a first embodiment of the invention plates 15 made of plastic, cement or metal, on which in the middle and parallel to the longitudinal edges extending two webs 17 are formed as holding elements. The distance D of the two webs 17 is slightly larger than the thickness d of the plate elements 7a, 7b. Instead of Webs 17 could also be provided in a line arranged pins or the like. A support member 13a can be placed in this way on the upper edge of the lower Abschalplatte 7b, which has been previously offset when laying the reinforcement. The support element 13a now forms a stable, flat bearing surface for a strip-shaped sealing film 19th

Nun kann das zweite Trägerelement 13b spiegelsymmetrisch auf die Dichtfolie 19 aufgelegt und, falls nötig, entlang der Ränder mit Eisenbindern 21 mit dem darunterliegenden Trägerelement 13b verbunden werden. Zum Hindurchführen der Eisenbinder 21 sind in den Plattenelementen 7a,7b Löcher 21 ausgebildet. Zwischen die Stege 17 am oben liegenden Trägerelement 13b kann nun das obere Plattenelement 7b eingesteckt werden. Danach können durch die Schwachstellen 9 die oberen Armierungseisen 11 hindurchgeführt werden. Beim Giessen des ersten Teilbauwerks 3 wird die flüssige Betonmasse durch die beiden Plattenelemente 7a und 7b am horizontalen Durchtritt zum zweiten Teilbauwerk 5 gehindert. Nach dem Giessen des zweiten Teilbauwerks 5 sind sowohl die Plattenelemente 7a und 7b als auch die Trägerelemente 13a und 13b sowie die dazwischen liegende Dichtfolie 19 vollständig in der Decke eingeschlossen und ein Durchtritt von Wasser, sei es von unten oder von oben, kann an der Stossstelle der zwei Teilbauwerke 3,5 nicht erfolgen.Now, the second support member 13b mirror-symmetrically placed on the sealing film 19 and, if necessary, along the edges with iron binders 21 are connected to the underlying support member 13b. For passing the iron binder 21, holes 21 are formed in the plate members 7a, 7b. The upper plate element 7b can now be inserted between the webs 17 on the upper carrier element 13b. After that, the upper reinforcing bars 11 can be passed through the weak points 9. When casting the first substructure 3, the liquid concrete mass is prevented by the two plate elements 7a and 7b on the horizontal passage to the second substructure 5. After casting the second substructure 5, both the plate elements 7a and 7b and the support elements 13a and 13b and the intermediate sealing film 19 are completely enclosed in the ceiling and a passage of water, whether from below or from above, can at the junction the two sub-structures 3.5 do not take place.

Analog zu einer Decke 1 kann die Verbindung zweier Wandabschnitte 23a und 23b, z.B. in einer Wasserfassung, einem Wasserreservoir oder einer Tunnelwand, also zwischen zwei vertikalen Teilbauten, abgedichtet werden (Figur 2).Analogously to a ceiling 1, the connection between two wall sections 23a and 23b, for example in an aqueous enclosure, a water reservoir or a tunnel wall, ie between two vertical substructures, can be sealed ( FIG. 2 ).

Alternativ zu einer ebenen Ausbildung der Platten 15 an den Trägerelementen 13a und 13b können diese auch V-förmig ausgebildet sein (siehe Figur 5).As an alternative to a planar design of the plates 15 on the carrier elements 13a and 13b, these may also be V-shaped (see FIG. 5 ).

In einer weiteren Ausbildung der Erfindung können anstelle von plattenförmigen Trägerelementen 13a,13b Drahtgitter eingesetzt werden (vergleiche Figuren 6-9). Die drahtgitterartig aufgebauten Trägerelemente 13a und 13b sind entlang von je einer Längskante gelenkig, beispielsweise durch Ringe 25 aus Draht, miteinander verbunden. Die Ringe 25 ermöglichen es, nach dem Aufsetzen des unteren Trägerelements 13a auf das Plattenelement 7a und dem Auflegen der bandförmigen Dichtfolie 19 das zweite Trägerelement 13b in Richtung des Pfeils P umzulegen (vergleiche Figur 6 rechte Seite). Anschliessend kann das obere Plattenelement 7b zwischen die Stege 17 eingelegt werden. Diese Ausführungsform vereinfacht das Verlegen der Dichtfolie 19 gegenüber dem Stand der Technik zusätzlich.In a further embodiment of the invention, instead of plate-shaped carrier elements 13a, 13b, wire meshes may be used (cf. Figures 6-9 ). The wire-like structure carrier elements 13a and 13b are articulated along each one longitudinal edge, for example, by rings 25 made of wire, connected to each other. The rings 25 make it possible, after placing the lower support member 13a on the plate member 7a and the laying of the band-shaped sealing foil 19, the second carrier element 13b in the direction of the arrow P reposition (see FIG. 6 right side). Subsequently, the upper plate member 7b can be inserted between the webs 17. This embodiment further simplifies the laying of the sealing film 19 over the prior art.

Um das untere Plattenelement 7a auf der Deckenschalung 27 auf einfache Weise positionieren und festhalten zu können, wird ein Haltebügel 29 mit einem oder mehreren Nägeln 31 durch ein aus dem Plattenelement 7a herausragendes Armierungselement 33 von unten hindurchgeführt und durch eine am vertikalen Schenkel des Haltebügels 11 ausgebildete Nase 35 gehalten (Figur 8). Ist kein Armierungselement 33 am Plattenelement 7a vorhanden, so kann am oberen Ende des Haltebügels 29 eine das Plattenelement 7a umgreifende Lasche 37 angeordnet sein (Figur 9). Um denselben Haltebügel 29 für unterschiedlich hohe Plattenelemente 7a einsetzen zu können, kann der untere Schenkel des Haltebügels 29 bogenförmig ausgebildet sein und durch jeweils zwei benachbarte Nägel 31 auf der Schalung 27 befestigt werden (keine Abbildung).In order to position the lower plate member 7a on the slab formwork 27 in a simple manner and to be able to hold, a headband 29 with one or more nails 31 by a protruding from the plate member 7a Arming element 33 passed from below and held by a formed on the vertical leg of the retaining clip 11 nose 35 ( FIG. 8 ). If no reinforcing element 33 is present on the plate element 7a, then a tab 37 embracing the plate element 7a can be arranged at the upper end of the holding clip 29 ( FIG. 9 ). In order to use the same headband 29 for different height plate elements 7a, the lower leg of the retaining clip 29 may be formed arcuate and fixed by two adjacent nails 31 on the formwork 27 (not shown).

In der Abbildung gemäss Figur 7 sind die Trägerelemente 13a,13b in einem rechten Winkel an der Stelle X miteinander verbunden. Auf diese Weise kann beim Giessen einer Betondecke 1 ein wasserdichter Anschluss zur später zu erstellenden Wand 39 hergestellt werden. Die unten in der Betondecke 1 zu liegen kommenden Trägerelemente 13a und die in der Wand 39 aussen zu liegen kommenden Trägerelemente 13a können fest miteinander verbunden sein. Die innen zu liegen kommenden beiden Trägerelemente 13b können einzeln aufgelegt oder ebenfalls mit den darunterliegenden Trägerelementen 13a entlang einer Kante gelenkig miteinander verbunden sein. Die bandförmige Dichtfolie 19 wird vor dem Giessen der Betondecke 1 an der Stelle X umgebogen und entlang des vertikal verlaufenden Schenkels des nach oben laufenden Trägerelements 13a an diesem befestigt (Figur 7).In the figure according to FIG. 7 the carrier elements 13a, 13b are interconnected at a right angle at the point X. In this way, when casting a concrete pavement 1, a watertight connection to the wall 39 to be created later can be produced. The lying below in the concrete ceiling 1 next support elements 13a and the outside to be placed in the wall 39 support members 13a can be firmly connected. The two support elements 13b coming inside can be placed individually or also connected to the underlying support elements 13a along one edge in an articulated manner. The band-shaped sealing foil 19 is bent before the casting of the concrete ceiling 1 at the point X and along the vertically extending leg of the upwardly running support member 13 a attached to this ( FIG. 7 ).

Mit einem gleichartig ausgebildeten Element kann der Anschluss der Wand 39 an die darüber zu liegen kommende Decke 1 erfolgen (keine Abbildung).With a similarly trained element, the connection of the wall 39 can be made to the coming to about 1 ceiling (no figure).

Auf die gleiche Weise wie bandförmige Dichtfolien 19 in Betondecken 1 und Wänden 39 eingelegt werden, lassen sich auch Dehnungsfugen-Abschalungen in Betondecken 1 und Wänden 39 positionieren. Figur 10 zeigt eine solche Dehnungsfuge in einer Betondecke 1. Anstelle der Plattenelemente 7a,7b für die Abschalung des ersten Teilbauwerks 3 zum zweiten Teilbauwerk 5 treten nun elastische Platten 41 aus z.B. Pavatex, EPS und andere, welche die Ausdehnung der beiden Teilbauwerke 1 und 2 ermöglichen. Die auch bei dieser Anwendung notwendige bandförmige Dichtfolie 19' weist in deren Zentrum einen Hohlraum, hier einen sechseckigen Hohlraum 43 auf, welcher Zug- und Druckbewegungen zwischen den beiden Teilbauwerken 3,5 schadlos aufnehmen kann. Die bandförmige Dichtfolie 19' wird auch in diesem Ausführungsbeispiel von Trägerelementen 13a und 13b während des Giessens der Decke 1 in Position gehalten. Im Beispiel der Trägerelemente 13a,13b gemäss Figur 10 sind letztere an einer Kante durch Ringe 25 gelenkig miteinander verbunden und bestehen aus Blech 45 oder aus Drahtgitter (keine Abbildung), welches zur optimalen Einbettung in den flüssigen Beton mit Aussparungen 47 versehen sind. Durch die Aussparungen 47 kann der flüssige Beton in innigen Kontakt mit der bandförmigen Dichtfolie 19 gelangen und so das Kriechen von Wasser entlang der Dichtfolie 19' unterbinden. Die Dehnungsplatte 41 kann selbstverständlich um 90° gedreht, in Wänden 39 eingesetzt werden.In the same way as band-shaped sealing foils 19 are inserted into concrete slabs 1 and walls 39, also expansion joint Abschalungen in concrete ceilings 1 and walls 39 can be positioned. FIG. 10 shows instead of the plate elements 7a, 7b for the shuttering of the first substructure 3 to the second substructure 5 now elastic plates 41 from eg Pavatex, EPS and others, which allow the extension of the two substructures 1 and 2. The band-shaped sealing foil 19 ', which is also necessary in this application, has in its center a cavity, in this case a hexagonal cavity 43, which can absorb tensile and compressive movements between the two substructures 3.5 without damage. The band-shaped sealing foil 19 'is held in position in this embodiment of support members 13a and 13b during the casting of the ceiling 1 in position. In the example of the support elements 13a, 13b according to FIG. 10 the latter are hinged together at one edge by rings 25 and consist of sheet metal 45 or wire mesh (not shown), which are provided with recesses 47 for optimal embedding in the liquid concrete. Through the recesses 47 For example, the liquid concrete can come in intimate contact with the band-shaped sealing foil 19 and thus prevent the creeping of water along the sealing foil 19 '. The expansion plate 41 can of course be rotated by 90 °, used in walls 39.

Die Trägerelemente 13a und 13b können sich über die gesamte Breite bzw. Länge der aneinanderstossenden Teilbauwerke 3,5 erstrecken. Es ist aber auch denkbar, die Trägerelemente 13a,13b als kurze Abschnitte auszubilden und diese beabstandet voneinander auf die Kanten der Plattenelemente 7a,7b aufzusetzen. Selbstverständlich muss dabei die Dichtfolie 19 über die gesamte Länge der Stossstellen geführt werden.The support elements 13a and 13b may extend over the entire width or length of the abutting substructures 3,5. However, it is also conceivable to form the carrier elements 13a, 13b as short sections and to set them apart from one another on the edges of the plate elements 7a, 7b. Of course, while the sealing film 19 must be performed over the entire length of the joints.
