Description
Steineisendecke mit Steinen halber Normalbreite im Bereich der negativen Momente Die Erfindung betrifft eine Verbesserung der Steineisendecken nach Patent 6692.44.Brick iron ceiling with stones half the normal width in the area of the negative Moments The invention relates to an improvement in the stone iron ceilings according to the patent 6692.44.
ach dem Hauptpatent besitzen die Steine halber Normalbreite im Bereich der negativen Momente unten an den Stohfugen durchgehende waagerechte Ausklinkungen, in die beim Vergießen der Decke Beton eingebracht wird, der sich mit dein Beton der senkrechten Rippen verbindet. Obwohl hierbei der vom Beton in waagerechter Richtung zurückzulegende Weg vergleichsweise kurz ist und dadurch die Bedingungen für das satte Ausfüllen der untenliegenden Druckzone günstig werden, wird wegen der breiigen Konsistenz des eingebrachten Betons eine weitere Sicherung des vollkoninienen Ausfüllens der Ausklinkungen und besonders die Möglichkeit, den Beton unter Druck einzubringen, erstrebt. Dieses Ziel wird nach der Erfindung dadurch erreicht, daß die Ausklinkungen sich von der Mitte der Steine nach den Seitenwandungen zu trichterförmig erweitern, wobei sowohl die obere wie die untere Begrenzung der Ausklinkungen nach oben hin ansteigen. Beim Ausfüllen dieser Ausklinkturgen erfährt der eingebrachte Beton keine plötzliche Richtungsumkehr; auch ergibt sich eine nur allmähliche Verengung der lichten Querschnitte.After the main patent, the stones have half the normal width in the area of the negative moments at the bottom of the hollow joints, continuous horizontal notches, into which concrete is poured when pouring the ceiling, which is then mixed with your concrete connecting vertical ribs. Although here the concrete in the horizontal direction the distance to be covered is comparatively short and therefore the conditions for the filling the pressure zone below will be cheap because of the mushy The consistency of the poured concrete is a further guarantee of the fully coninienced filling the notches and especially the possibility of placing the concrete under pressure, strives. This object is achieved according to the invention in that the notches expand from the middle of the stones to the side walls to form a funnel, both the upper and the lower limit of the notches towards the top increase. When filling out these notches, the poured concrete does not experience any sudden change of direction; there is also only a gradual narrowing of the clear cross-sections.
Gegenüber dem Hauptpatent bietet die Erfindung den weiteren Vorteil, daß die Ausklinkungen in an sich bekannter Weise eine untere Begrenzung aus Steinbaustoff erhalten, so daß die Betonstreifen abgedeckt werden und nicht durch den Putz der Decke durchscheinen. Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes in Abb. i ini senkrechten Querschnitt und in Abb. 2 im Längsschnitt nach der Linie II-II der Abb. i dargestellt.Compared to the main patent, the invention offers the further advantage that the notches in a known manner a lower limit made of stone building material received so that the concrete strips are covered and not by the plaster of the Shine through the ceiling. The drawing shows an embodiment of the subject matter of the invention in Fig. 1 in a vertical cross-section and in Fig. 2 in a longitudinal section along the line II-II of Fig. I.
Bei c und d sind zwei Deckensteine mit halber Normalbreite angedeutet. Zwischen den Steinen c und d befindet sich eine senkrechte Aussparung e in der Längsrichtung der Steine für die Rippen. Unten an den Stoßfugen besitzen die Steine waagerechte Ausklinkungen a. An ihrer Oberseite werden die Ausklinkungen a durch die schrägen Flächen f begrenzt. Unten erfolgt der Abschluß der Ausklinkungen a durch die Steinplättchen g, die in der Mitte des Steines ihre kleinste Stärke haben und nach den Seiten hin stärker werden, so daß die ansteigenden Flächen 1i entstehen, die für den von e her einfließenden Beton eine Leitfläche bilden.At c and d two ceiling stones with half the normal width are indicated. Between the stones c and d there is a vertical recess e in the longitudinal direction the stones for the ribs. At the bottom of the butt joints, the stones have horizontal ones Notches a. On their top, the notches a are through the bevels Areas f limited. At the bottom, the notches a are completed by the stone plates g, which have their smallest thickness in the middle of the stone and towards the sides become stronger, so that the rising surfaces 1i arise, which for the of e flowing concrete form a guiding surface.
Es ist auch möglich, die Plättchen g mit den zugehörigen Deckensteinen aus einem Stück herzustellen; wirtschaftlicher ist es jedoch, besondere Steinplättchen vorzusehen.It is also possible to use the plate g with the associated ceiling tiles to be made from one piece; It is more economical, however, to use special stone tiles to be provided.
