Description

Zur Unterbrechung grosser Flächen eines Bauwerkes aus Betonstahl, wie Böden oder Decken einer Einstellhalle, wurden bis jetzt für zwei Betonieretappen Abschalungen aus Holzplatten verwendet. Solche Abschalungen müssen auf der Baustelle auf die verlangte Länge und Höhe zugeschnitten und ausserdem in denselben Bohrungen, die zum Durchführen von Armierungsstäben dienen, gebohrt werden. Auster der zeitlich aufwendigen Aufbereitung einer solchen Abschalung muss diese nach dem Betonieren der ersten Etappe von dem hart gewordenen Beton abgerissen werden. Dann muss die gegen die zweite zu betonierende Etappe weisende Oberfläche der ersten ausgehärteten Betonieretappe aufgerauht werden, um eine gute Verbindung der beiden Betonieretappen zu erzielen.To interrupt large areas of a reinforcing steel structure, such as the floors or ceilings of a parking garage, formwork made of wooden panels has been used for two concreting stages. Such formwork must be cut to the required length and height on the construction site and must also be drilled in the same holes that are used to carry out reinforcing bars. In view of the time-consuming preparation of such formwork, it has to be demolished from the hardened concrete after the first stage has been concreted. Then the surface of the first hardened concreting stage pointing towards the second stage to be concreted must be roughened in order to achieve a good connection between the two concreting stages.

Es ist auch bekannt, Streckmetall als dünnwandige, geschwungene, verlorene Abschalung für Decken oder andere Bauobjekte zu verwenden.Das in flachen Tafelngelieferte und verwendete Streckmetall eignet sich aber nur bedingt als Abschalung für zwei.zu betonierende Etappen eines Bauwerkes, welche Etappen miteinander gut verbunden werden sollen. Bei der Verwendung von Abschalungen aus flachen Streckmetalltafeln entsteht eine nicht sauber geformte Stirnfläche der ersten Betonieretappe, die auch ohne Verzahnung ist.It is also known to use expanded metal as a thin-walled, curved, lost formwork for ceilings or other construction objects should. When using formwork made from flat expanded metal panels, the end face of the first stage of concreting, which is not cleanly formed, is also without gearing.

In dem Schweizer Patentgesuch Nr. 4073/79 ist ein profiliertes Element aus Streckblech beschrieben, das als Mittel zur Schaffung eines Anschlusses für ein Bauwerk, wie Zwischenwand, Treppe oder Zwischenboden an einer in einer Schalung zu betonierenden Wand verwendet wird.In Swiss patent application No. 4073/79 a profiled element made of expanded metal is described, which as Means for creating a connection for a building, such as partition wall, stairs or intermediate floor is used on a wall to be concreted in a formwork.

Es ist die Aufgabe der Erfindung, eine Verwendung von im Bauwesen bekannten Mitteln vorzuschlagen, die einen einfachen und zeitsparenden Vorgang beim Betonieren von zwei Etappen eines Bauwerkes ermöglicht und eine einwandfreie Verbindung der beiden Betonieretappen gewährleistet. Diese Aufgabe wird auf solche Weise gelöst, dass mindestens ein aus Streckmetall bestehendes, Löcher zum Durchführen von Armierungsstäben aufweisendes Profilelement als verlorene Abschalung für zwei zu betonierende Etappen eines Bauwerkes verwendet wird.It is the object of the invention to propose a use of means known in the construction industry, which enables a simple and time-saving process when concreting two stages of a building and ensures a perfect connection of the two concreting stages. This object is achieved in such a way that at least one profile element consisting of expanded metal and having holes for the passage of reinforcing bars is used as lost formwork for two stages of a building to be concreted.

Mit Vorteil können mehrere Profilelemente auf und nebeneinandergelegt und vor der Betonierung der ersten Etappe einerseits von Stützmitteln abgestützt werden.Advantageously, several profile elements can be placed on and next to each other and supported on the one hand by proppants before the first stage is concreted.

Die Erfindung wird anhand der Zeichnung beispielsweise näher erläutert. Es zeigen

  • Fig. l eine perspektivische Ansicht einer aus profiliertem Streckblechelement bestehenden Abschalung für zwei zu betonierende Etappen eines Bauwerkes, die von Holzkeilen abgestützt ist,
  • Fig. 2 einen Querschnitt des Profilelementes nach der Fig. l, nachdem die erste Etappe des Bauwerkes betoniert und die Holzkeile von dem Profilelement abgeschlagen wurden,
  • Fig. 3 einen Querschnitt von zwei aufeinanderliegenden, an Holzkeilen befestigten Profilelementen nach der Fig. 1 und
  • Fig. 4 einen Querschnitt von aufeinanderliegenden, an Holzkeilen befestigten Profilelementen einer anderen Ausführungsform.
The invention is explained in more detail with reference to the drawing, for example. Show it
  • 1 is a perspective view of a formwork consisting of profiled sheet metal element for two stages of a building to be concreted, which is supported by wooden wedges,
  • 2 shows a cross section of the profile element according to FIG. 1 after the first stage of the building has been concreted and the wooden wedges have been knocked off the profile element,
  • Fig. 3 shows a cross section of two superimposed, attached to wooden wedges profile elements according to FIGS. 1 and
  • Fig. 4 shows a cross section of superimposed, attached to wooden wedges profile elements of another embodiment.

Das in den Figuren dargestellte Profilelement 1, das als verlorene Abschalung für zwei zu betonierende Etappen eines nicht dargestellten Bauwerkes verwendet wird, besteht aus Streckmetall; es kann aber auch z.B. aus einem gezinkten, gestanzten, gedruckten oder verrippten Stahlblech bestehen, wodurch die Oberfläche des Bleches rauh gemacht wird. Die gleichmässig aufgerauhte Oberfläche gibt nämlich eine optimale Verbindungsmöglichkeit zwischen zwei Betongüssen eines Bauwerkes. Wie aus der Fig. 2 ersichtlich ist, ist das Profilelement 1 im Querschnitt Doppel-U-förmig mit einem Steg. Der Querschnitt des Profilelementes 1 kann aber auch U-förmig (siehe die Fig. 4) oder trapez-, mäander- oder wellenförmig sein oder eine Kombination dieser Formen haben.The profile element 1 shown in the figures, which is used as lost formwork for two stages to be concreted of a building, not shown, consists of expanded metal; But it can also, for example, from a marked, stamped, printed or ribbed steel sheet, which makes the surface of the sheet rough. The evenly roughened surface gives an optimal connection between two concrete castings of a building. As can be seen from FIG. 2, the profile element 1 is double U-shaped in cross section with a web. The cross section of the profile element 1 can also be U-shaped (see FIG. 4) or trapezoidal, meandering or undulating or have a combination of these shapes.

Durch das Profilelement 1 sind in der Nähe seiner äusseren Längskanten Löcher 2 durchgestanzt, die jeweils eine parallel mit der Längskante des Profilelementes verlaufende Reihe von Löchern bilden. Diese Löcher 2 sind für Armierungsstäbe 5 bestimmt, die durch sie durchgeführt und in den beiden Etappen des Bauwerks einbetoniert werden. Die Entfernung der Löcher 2 von den äusseren Längskanten des Profilelementes 1 wird von dem Statiker je nach der Art des Bauwerkes bestimmt. Pro Loch 2 wird ein Armierungsstab 5 verwendet.Holes 2 are punched through the profile element 1 in the vicinity of its outer longitudinal edges, each forming a row of holes running parallel to the longitudinal edge of the profile element. These holes 2 are intended for reinforcing bars 5, which are carried out by them and concreted in in the two stages of the structure. The distance of the holes 2 from the outer longitudinal edges of the profile element 1 is determined by the structural engineer depending on the type of building. A reinforcing bar 5 is used per hole 2.

Das Profilelement 1 wird vor dem Betonieren der ersten Betonieretappe des Bauwerkes einerseits von mehreren Holzkeilen 3 abgestützt (siehe die Figuren). Anstelle von Holzkeilen können auch Stahlwinkel verwendet werden. Mehrere Profilelemente 1 können ohne gegenseitige Verbindung aufeinander- und nebeneinandergelegt werden, wobei sie nur an den Holzkeilen 3 mittels Befestigungsmittel 4 festgehalten werden. Die Profilelemente 1.. werden lose auf Holzeinlagen 7 gelegt, die sich auf der Schalung 8 über die gesamte Länge der Profilelemente 1 erstrecken. Anstelle von Holz kann auch ein anderes Material, wie Kunststoff verwendet werden. Nach dem Betonieren der ersten Etappe 6 werden die Holzkeile 3 und Holzeinlagen 7 von dem bzw. den Profilelementen 1 entfernt und können weiterverwendet werden. Nach dem Aushärten des Betons der ersten Betonieretappe 6 und nach der Entfernung der Holzkeile 3 wird die zweite Etappe des Bauwerkes betoniert.The profile element 1 is supported on the one hand by several wooden wedges 3 before concreting the first concreting stage of the building (see the figures). Instead of wooden wedges, steel angles can also be used. A plurality of profile elements 1 can be placed one on top of the other and next to one another without mutual connection, wherein they are only held on the wooden wedges 3 by means of fastening means 4. The profile elements 1 .. are placed loosely on wooden inserts 7 which extend over the entire length of the profile elements 1 on the formwork 8. Instead of wood, another material, such as plastic, can also be used. After concreting the first stage 6, the wooden wedges 3 and wooden inserts 7 are removed from the profile element or elements 1 and can be used further. After the concrete of the first concreting stage 6 has hardened and the wooden wedges 3 have been removed, the second one Concrete stage of the building.

Die Dicke des feinmaschigen Streckmetalls, aus welchem das Profilelement 1 besteht, beträgt mit Vorteil 0,7 bis 1,5 mm.The thickness of the fine-mesh expanded metal from which the profile element 1 is made is advantageously 0.7 to 1.5 mm.

Da das Profilelement bzw. die Profilelemente 1 nach dem Aushärten des Betons der ersten Etappe 6 an ihrer Stirnfläche haften bleibt bzw. bleiben, wird diese Stirnfläche dementsprechend profiliert. Dadurch wird eine einwandfreie Verzahnung der zweiten Betonieretappe mit der ersten Betonieretappe erreicht.Since the profile element or the profile elements 1 remains or remain attached to its end face after the concrete of the first stage 6 has hardened, this end face is profiled accordingly. This ensures perfect interlocking of the second concreting stage with the first concreting stage.

Die Montage des Prof-ilelementes, das ein geringeres Gewicht als z.B. Holzplatten hat, ist viel leichter als bei der herkömmlichen Holzschalung. Die fertigen Profilelemente werden z.B. in Längen von 250 cm aus der Werkstatt geliefert; sie brauchen nicht auf der Baustelle zugeschnitten zu werden. Da die Löcher 2 in jedem Profilelement 1 in der gewünschten Teilung schon vorgestanzt sind, brauchen sie auf der Baustelle nicht mühsam verfertigt zu werden. Nach dem vollendeten Betonieren der beiden Etappen wird das Profilelement bzw. die Profilelemente nicht entfernt; somit wird eine verlorene Abschalung gebildet, so dass die Ausschalarbeiten eliminiert werden und die Stirnfläche der ersten Betonieretappe nicht aufgerauht werden muss. Die einzelnen Profilelemente können in der Höhe und Länge beliebig zusammengefügt werden. Die Verzahnung der beiden Betonieretappen wird ohne zusätzlichen Arbeitsaufwand erreicht. Es wird eine kompakte Oberfläche der Betonieretappen ohne Luftblasen erzielt.The assembly of the profile element, which is lighter than e.g. Having wooden panels is much lighter than with conventional wooden formwork. The finished profile elements are e.g. delivered from the workshop in lengths of 250 cm; they do not need to be cut on site. Since the holes 2 are already pre-punched in the desired division in each profile element 1, they do not have to be laboriously manufactured on the construction site. After the concreting of the two stages has been completed, the profile element or the profile elements is not removed; thus a lost formwork is formed, so that the formwork work is eliminated and the end face of the first concreting step does not have to be roughened. The height and length of the individual profile elements can be combined as required. The interlocking of the two concreting stages is achieved without additional work. A compact surface of the concreting stages without air bubbles is achieved.
