Claims (1)

<Desc/Clms Page number 1>  <Desc / Clms Page number 1>   Die Erfindung betrifft ein vorgefertigtes verlorenes Schalungselement für die Herstellung von insbesondere geneigten, mit einer aus selbsttragenden Bewehrungsträgern, vorzugsweise Gitterträgern bestehenden Bewehrung versehenen Stahlbetondecken mit zwei die fertige Wand- bzw. Deckenoberfläche bildenden Grundplatten.  The invention relates to a prefabricated lost formwork element for the production of, in particular, inclined reinforced concrete ceilings provided with a reinforcement consisting of self-supporting reinforcement beams, preferably lattice girders, with two base plates forming the finished wall or ceiling surface. Die Herstellung einer Stahlbetonwand ist dann etwas problematisch, wenn sie zur Bildung von schrägen Decken, z. B. bei Dachausbauten verwendet werden soll, wobei eine "verlorene Schalung" aus beliebigem Material, die zugleich auch die fertige Wandoberfläche darstellt, zur Anwendung gelangt. In diesem Fall sollte die "verlorene Schalung" aus zwei die fertigen Wand- bzw.  The production of a reinforced concrete wall is somewhat problematic when it is used to form sloping ceilings, e.g. B. to be used in loft conversions, a "lost formwork" of any material, which also represents the finished wall surface, is used. In this case the "lost formwork" should consist of two finished wall or Deckenoberflächen bildenden Grundplatten bestehen, und es wäre ferner von Vorteil, die "verlorene Schalung" für eine solche Wand oder schräge Decke in zwei Teilen herstellen zu können, um sie leicht zwischenlagern, auf das gewünschte Format zuschneiden, transportieren und erst zu einem späteren Zeitpunkt zusammenfügen zu können. Dabei bestünde auch der Vorteil, dass man je nach den Anforderungen in die Schalung Ausschnitte und Öffnungen vorsehen sowie Leitungen oder Zusatzbewehrungen einlegen könnte und dies unabhängig von dem eigentlichen Setzvorgang der Schalung auf der Baustelle. Base plates forming ceiling surfaces exist, and it would also be advantageous to be able to produce the "lost formwork" for such a wall or sloping ceiling in two parts so that it can be temporarily stored, cut to the desired format, transported and only put together at a later date to be able to. There would also be the advantage that, depending on the requirements, cutouts and openings could be provided in the formwork, and cables or additional reinforcements could be inserted, regardless of the actual setting process of the formwork on the construction site. Um dies durchführen zu können, wird erfindungsgemäss vorgeschlagen, dass auf den Grundplatten in parallelen Reihen in Abständen vorzugsweise im Querschnitt pilzförmig ausgebildete Anker aufgesetzt und mit den Grundplatten kraftschlüssig verbunden sind, und dass die Längs- bzw.  In order to be able to carry this out, it is proposed according to the invention that anchors which are mushroom-shaped in cross section, preferably in cross section, are placed on the base plates in parallel rows and are non-positively connected to the base plates, and that the longitudinal or Zugstäbe der zugleich als Abstandhalter dienenden Bewehrungsträger die Köpfe der Anker beider Grundplatten untergreifen oder in an den Ankern ausgebildeten Einschnitten eingreifen. Tension rods of the reinforcement beams, which also serve as spacers, reach under the heads of the anchors of both base plates or engage in incisions formed on the anchors. Nachstehend soll die Erfindung an Hand der Zeichnung näher erläutert werden.  The invention will be explained in more detail below with reference to the drawing. Wie der Zeichnung zu entnehmen ist, sind zwei parallele Grundplatten --4-- vorgesehen, auf denen in parallelen Reihen und im Abstand pilzförmig ausgebildete Anker --1-- vorgesehen sind. Diese Anker sind mit den Grundplatten --4-- kraftschlüssig verbunden, sei es durch Kleben, Nageln oder Schrauben --3--. Die Anker --1-- haben im vorliegenden Fall eine ringförmige Nut - -2--, in denen die Zugstäbe --5-- von beispielsweise X-förmigen Gitterträgern --6-- eingreifen und so je zwei einander gegenüberliegende Anker-l-und damit die beiden Grundplatten --4-fest miteinander zusammenhalten.  As can be seen in the drawing, two parallel base plates --4-- are provided, on which anchors --1-- which are mushroom-shaped are provided in parallel rows and at a distance. These anchors are non-positively connected to the base plates --4--, whether by gluing, nailing or screwing --3--. In the present case, the anchors --1-- have an annular groove - -2--, in which the tension rods --5-- of, for example, X-shaped lattice girders --6-- engage and thus two mutually opposite anchor-l -and hold the two base plates together - 4-firmly. Das Zusammenfügen der Schalung kann auf der Baustelle leicht dadurch ausgeführt werden, dass die X-förmigen Gitterträger --6-- im Bereich ihrer Zugstäbe --5-- etwas gedehnt und über den konisch ausgebildeten Oberteil --7-- einrasten.  The formwork can be easily assembled at the construction site by slightly extending the X-shaped lattice girders --6-- in the area of their tie rods --5-- and snapping them over the conically shaped upper part --7--. Es ist ersichtlich, dass man je nach Erfordernis, z. B. entsprechend den statischen Bedingungen, den Abstand der Ankerreihen variieren und auch die Stahlträger selbst beliebig bemessen kann. Die gleichen Anker können somit verschieden gross und in ihrer Festigkeit entsprechend bemessene Stahlträger aufnehmen. Eine weitere Möglichkeit besteht im Einlegen einer Zusatzbewehrung.  It can be seen that depending on the requirement, e.g. B. vary according to the static conditions, the distance between the rows of anchors and the steel beam itself can be dimensioned arbitrarily. The same anchors can therefore accommodate steel girders of different sizes and strength. Another option is to insert additional reinforcement. Weitere sich aus dem erfindungsgemässen Vorschlag ergebende Effekte sind darin zu sehen, dass man im Werk lediglich die Grundplatte --4-- mit den aufgesetzten Ankern --1-- herstellt und vorrätig hält. Je nach Bedarf kann man derartige Grundplatten mit Ausschnitten versehen und auch hinsichtlich ihrer äusseren Abmessungen zurechtschneiden. Die gitterförmigen Träger --6-- könnten bereits im Werk auf eine der Platten aufgesetzt werden. Es ergibt sich somit eine erhebliche Erleichterung in der Lagerhaltung, da man vorbereitete Standardgrössen von Grundplatten leicht stapeln kann. Auf der Baustelle ist das Versetzen mit einfachen Hebezeugen ohne Schwierigkeiten durchführbar. Nach dem Einbringen des Betons liegt eine Stahlbetondecke vor, deren "verlorene Schalung" die Aussenseiten der Decke bildet. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**.  Further effects resulting from the proposal according to the invention can be seen in the fact that only the base plate --4-- with the attached anchors --1-- is manufactured and kept in stock in the factory. Depending on requirements, such base plates can be provided with cutouts and also cut to size with regard to their outer dimensions. The grid-shaped supports --6-- could already be placed on one of the plates at the factory. This considerably simplifies storage, since standard sizes of base plates can easily be stacked. On the construction site, moving with simple hoists is no problem. After the concrete has been poured in, there is a reinforced concrete ceiling, the "lost formwork" of which forms the outside of the ceiling. ** WARNING ** End of CLMS field knows overlap beginning of DESC **.
