A prefabricated shuttering element for the construction of reinforced concrete ceilings, with a building panel, which is flat on the room side, is provided with reinforcement and which serves as a permanent shuttering, and with steel lattice supports as the principal reinforcement above the building panel which is supported by retaining means secured to it and provided with an angular or round base and an undercut head part, characterised in that the retaining means are mushroom-shaped anchors (1, 15) connected in force-locking manner with the building panel (4, 14, 14'), wherein the longitudinal or tension rods (8, 18) of the reinforcement supports (7, 19) engage under the heads (6, 20) of the mushroom-shaped anchors or engage in recesses (5, 17) formed in the anchors so as to provide a self-supporting shuttering element which after being installed can be concreted without supports.

Description

Die Erfindung betrifft eine Methode zur Herstellung von Stahlbetondecken mit putzfertiger Untersicht, wobei die erfindungsgemäße Stahlbetondecke besonders günstige Transport- und Versetzmöglichkeiten bieten soll. Auch sollen die jeweils gewünschten Abmessungen gegebenenfalls erst auf der Baustelle festgelegt werden können, wo auch Abänderungen kurzfristig erffolgen könnten.The invention relates to a method for producing reinforced concrete ceilings with a ready-to-plaster bottom view, the reinforced concrete ceiling according to the invention being intended to offer particularly favorable transport and transfer options. The desired dimensions should also only be able to be determined at the construction site, where changes could be made at short notice.

Ein weiterer Vorteil soll darin bestehen, daß die zu der Baustelle zu transportierenden Elemente hinsichtlich ihres Gewichts relativ leicht sind und mit einfachen mechanischen Hilfsmitteln, z.B. Leichtkränen, versetzt werden können. Bei der Herstellung von Decken im Selbstbau benötigt man häufig nur kleine Deckenelemente, deren Herstellung händisch - ohne Kran - durchgeführt werden kann.Another advantage should be that the elements to be transported to the construction site are relatively light in terms of their weight and with simple mechanical aids, e.g. Light cranes can be moved. When manufacturing self-made ceilings, you often only need small ceiling elements, which can be produced manually - without a crane.

Das Wesentliche der erfindungsgemäßen Stahlbetondecke besteht aus einer Grundplatte mit auf dieser in parallelen Reihen in Abständen aufgesetzten und mit der Platte kraftschlüssig verbundenen Ankern, die vorzugsweise im Querschnitt pilzförmig ausgebildet sind. Auf der Grundplatte sind selbsttragende Bewehrungsträger zwischen den Ankerreihen angeordnet, die die Köpfe der Anker untergreifen oder in an den Ankern ausgebildeten Einschnitten eingreifen. Nach dem Einklinken der Bewehrungsträger zwischen zwei parallelen Ankerreihen und dem Aufsetzen dieser nunmehr fest miteinander verbundenen Teile auf entsprechende Stützlager des zu errichtenden Baues erfolgt das: Einbringen des Betons auf die Grundplatte als sogenannte verlorene Schalung.The essence of the reinforced concrete ceiling according to the invention consists of a base plate with anchors placed on it in parallel rows at intervals and non-positively connected to the plate, which are preferably mushroom-shaped in cross section. Self-supporting reinforcement beams are arranged on the base plate between the rows of anchors, which engage under the heads of the anchors or engage in incisions formed in the anchors. After the reinforcement beams have been latched in between two parallel rows of anchors and these parts, which are now firmly connected to each other, are placed on the corresponding support bearings of the building to be erected, the concrete is placed on the base plate as so-called lost formwork.

Je nach Wunsch können die Bewehrungsträger statisch so ausgeführt werden, daß entweder gar keine oder nur geringfügige Unterstellungen anzuordnen sind, um die Stahlbetondecke während der Abbindezeit des Betons ausreichend abzustützen.Depending on your needs, the reinforcement beams can be designed statically so that either no or only minor supports are to be arranged in order to adequately support the reinforced concrete ceiling during the setting time of the concrete.

Mit Vorteil werden die Schalungsteile der Decke bereits im Werk zusammengesetzt und danach aufeinander gestapelt und gelagert.Advantageously, the formwork parts of the ceiling are assembled in the factory and then stacked and stored on top of each other.

Soweit erforderlich, können in die Einschnitte der Anker auch Stäbe einer Zusatzbewehrung eingelegt werden. Diese Bewehrung kann sowohl im Werk als auch erst auf der Baustelle verlegt werden. Somit verfügt man über ein leicht zu-versetzendes und ohne Schwierigkeiten zu transportierendes Element, das aus einer verlorenen Schalung, der erforderlichen Deckenbewehrung und den erwähnten pilzförmigen Ankern besteht, und in das dann - nach dem Versetzen auf der Baustelle - nur mehr der erforderliche Beton eingebracht werden muß, um die fertige Stahlbetondecke zu erhalten.If necessary, rods can also be inserted into the incisions of the anchors Additional reinforcement can be inserted. This reinforcement can be installed both in the factory and only on the construction site. So you have an easy-to-move and easy-to-transport element, which consists of lost formwork, the required ceiling reinforcement and the aforementioned mushroom-shaped anchors, and into which - after moving to the construction site - only the required concrete is poured must be to get the finished reinforced concrete floor.

Sobald der Versetzvorgang abgeschlossen ist, können wie bei herkömmlichen Ortbetondecken die Installationen eingelegt und die Betonierarbeiten durchgeführt werden.As soon as the moving process is complete, the installations can be inserted and the concreting work carried out, as with conventional in-situ concrete ceilings.

Die Herstellung einer solchen Betonwand 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 fertige Wand- bzw.Deckenaberflächen 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 zusammenzufügen zu können. Dabei bestünde auch der Vorteil, daß man je nach den Anforderungen in die Schalung Ausschnitte und Öffnungen vorsehen sowie Leitungen öder Zusatzbewehrungen einlegen könnte und dies unabhängig von dem eigentlichen Setzvorgang der Schalung auf der Baustelle.The production of such a concrete wall is somewhat problematic if it is used to form sloping ceilings, e.g. to be used in roof extensions, whereby 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 base plates which form the finished wall or ceiling surfaces, and it would also be advantageous to be able to produce the "lost formwork" for such a wall or sloping ceiling in two parts in order to be able to produce it can be stored temporarily, cut to the required format, transported and only put together at a later point in time. There would also be the advantage that, depending on the requirements, cutouts and openings could be provided in the formwork and lines 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 in weiterer Ausgestaltung der Erfindung vorgeschlagen, daß parallel zur Grundplatte im Abstand eine zweite Grundplatte mit auf dieser in Reihen in Abständen aufgesetzten und mit dieser Grundplatte verbundenen Ankern vorgesehen ist, wobei vorzugsweise X-förmige Gitterträger mit ihren Zugstäben die einander gegenüberliegenden Köpfe der Anker beider Grundplatten untergreifen und diese als "verlorene Schalung" der Stahlbetonwand fest miteinander verbinden.In order to be able to carry this out, it is proposed according to the invention in a further embodiment of the invention that a second base plate is provided parallel to the base plate at a distance with anchors placed on it in rows at intervals and connected to this base plate, preferably X-shaped lattice girders with their tension rods reach under the opposite heads of the anchors of both base plates and firmly connect them together as "lost formwork" of the reinforced concrete wall.

Nachstehend soll die Erfindung anhand der Zeichnungen näher erläutert werden, in denen Fig. 1 eine Grundplatte zeigt, auf der rasterartig pilzförmig ausgebildete Anker in parallelen Reihen aufgebracht sind. Fig. 2 veranschaulicht perspektivisch eine Vorrichtung, mit der die Anker auf eine Grundplatte maschinell aufgesetzt werden können. Fig. 3 zeigt aufeinander gestapelte Grundplatten samt aufgesetzten Ankern für eine raumsparende Lagerung oder für den Transport zur Baustelle. Fig.4 ist die perspektivische Darstellung eines versetzfertigen Elementes. Die Fig. 5 - 12 zeigen in Ansicht bzw. in Draufsicht verschiedene Ausführungsformen von Ankern. Fig. 13 veranschaulicht eine weitere Ausführungsform der Erfindung.The invention will be explained in more detail below with reference to the drawings, in which FIG. 1 shows a base plate on which a mushroom-like pattern is formed trained anchors are applied in parallel rows. 2 illustrates in perspective a device with which the anchors can be placed mechanically on a base plate. Fig. 3 shows stacked base plates with attached anchors for space-saving storage or for transport to the construction site. Figure 4 is a perspective view of a ready-to-move element. 5-12 show different embodiments of anchors in a view or in plan view. 13 illustrates another embodiment of the invention.

Die pilzförmig ausgebildeten Anker 1 bestehen im wesentlichen aus einem plattenförmigen Fuß 2, dessen Unterseite glatt, gerillt bzw. strukturiert oder auch gelocht sein kann, und eventuell Stife 3 aufweist, um den auf eine Schalungsplatte 4 aufgesetzten Anker 1 mit der Platte während des Leimvorganges in horizontaler Richtung gegen Verschieben zu sichern. Anstelle dieser beiden Stifte (Nägel) kann der Anker auch ein Loch aufweisen, durch welches man einen Nagel schlägt.The mushroom-shaped anchors 1 essentially consist of a plate-shaped base 2, the underside of which can be smooth, grooved or structured or also perforated, and possibly have pins 3 around the anchor 1 placed on a formwork panel 4 with the panel during the gluing process in secure in the horizontal direction against displacement. Instead of these two pins (nails), the anchor can also have a hole through which a nail is struck.

Die Anker 1 werden entsprechend dem auf der Grundplatte 4 in Fig. 1 angedeuteten Raster in prallelen Reihen versetzt, z.B. nach Aufbringen eines Klebers auf der Ankerunterseite mit einem Hammer auf die Grundplatte 4 aufgeklopft, wobei die Stifte 3 des Ankers in das Material der Platte eindringen und so eine genaue Fixierung ermöglichen. Entsprechend der pilzförmigen Ausgestaltung der Anker weisen diese einen verjüngten Zwischenteil bzw. Einschnitt 5 auf, der sich am oberen Ende wieder erweitert und einen pilzförmigen Kopf 6 bildet.The anchors 1 are displaced in parallel rows in accordance with the grid indicated on the base plate 4 in FIG. 1, e.g. after applying an adhesive on the underside of the anchor, tap it onto the base plate 4 with a hammer, the pins 3 of the anchor penetrating into the material of the plate and thus allowing precise fixing. According to the mushroom-shaped design of the anchors, they have a tapered intermediate part or incision 5, which widens again at the upper end and forms a mushroom-shaped head 6.

Je nach dem Material, aus dem die Anker 1 bestehen, können diese gegebenenfalls auch mit der Grundplatte 4 verschweißt oder auch verschraubt werden.Depending on the material from which the anchors 1 are made, these can optionally also be welded or screwed to the base plate 4.

Zwischen den Ankerreihen wird eine freigespannte Bewehrung z.B. in Form eines Gitterträgers 7"eingebracht, wie dies am besten der Fig.4 zu entnehmen ist. Dieses Einbringen der Bewehrung erfolgt zweckmäßig durch Einklinken der unteren, die Zugkräfte übertragenden Längsstäbe 8 des Gitterträgers. Es versteht sich, daß jeder geeignet ausgebildete Gitterträger Verwendung finden kann. Entsprechend der Belastung beim Einbringen des Betons auf die verlorene Schalung sind die Abstände zwischen den Ankern 1 in Längs-und Querrichtung zu bemessen.A free-spanned reinforcement, for example in the form of a lattice girder 7 ", is introduced between the rows of anchors, as can best be seen in FIG. 4. This reinforcement is advantageously introduced by latching the lower longitudinal bars 8 of the lattice girder, which transmit the tensile forces. It goes without saying that any appropriately trained lattice girder can be used, depending on the load when placing the concrete on the lost formwork, the distances between the anchors 1 are measured in the longitudinal and transverse directions.

Als Grundplatte 4, die eine verlorene Schalung darstellt, eignen sich die verschiedensten Materialien, z.B. Holzplatten, Verbundplatten, Asbest-Zementplatten, Holz-Zementplatten, Kunststoff- u. Metallplatten u.dgl.. Da die Grundplatte 4 als verlorene Schalung zugleich die fertige Deckenuntersicht bilden kann, ist es zweckmäßig, für die Schalung ein Material mit einer Struktur zu wählen, mit der man das gewünschte endgültige Aussehen der Decke erzielen kann.A wide variety of materials are suitable as the base plate 4, which represents lost formwork, e.g. Wood panels, composite panels, asbestos cement panels, wood cement panels, plastic and. Metal plates and the like. Since the base plate 4 can also form the finished ceiling view as lost formwork, it is advisable to choose a material for the formwork with a structure with which the desired final appearance of the ceiling can be achieved.

Für größere Deckenspannweiten bzw. Deckenbelastungen kann auch eine Zusatzbewehrung z. B. aus Baustahlmatten, neben den Längsstäben 8 der Gitterträger 7 eingelegt werden. Die Anker 1 dienen in diesem Fall zugleich als Abstandhalter sowohl für die einzuklinkende selbsttragende Bewehrung als auch für die Zusatzbewehrung.For larger ceiling spans or ceiling loads, additional reinforcement z. B. from steel mats, next to the longitudinal bars 8 of the lattice girder 7 are inserted. In this case, the anchors 1 serve as spacers both for the self-supporting reinforcement to be latched in and for the additional reinforcement.

Es versteht sich von selbst, daß für die Herstellung der Anker 1 die verschiedensten Materialien herangezogen werden können, z.B. Kunststoff, Metall und Holz.It goes without saying that a wide variety of materials can be used for the manufacture of the anchors 1, e.g. Plastic, metal and wood.

Die erfindungsgemäße Stahlbetondecke ermöglicht den Vorteil, daß keine Unterstellung bei der endgültigen Herstellung der der Baustelle erforderlich ist. Es ist zu erkennen, daß Elemente von beliebiger Größe erst auf der Baustelle zugeschnitten und je nach vorhandenem Hebezeug, also auch händisch, versetzt werden können.The reinforced concrete ceiling according to the invention has the advantage that no subordination is required for the final manufacture of the construction site. It can be seen that elements of any size can only be cut to size on the construction site and can be moved by hand, depending on the lifting equipment available.

Wie in Fig. 2 dargestellt ist, kann man auch Elemente mittels einer einfachen Vorrichtung ist Werk erstellen, wobei diese Elemente eine beliebige Länge entsprechend üblicher im Handel erhältlicher Platten und eine Breite, die ein einfaches Transportieren vom Werk zur Baustelle zuläßt, aufweisen können. Auf die auf einen Tisch 9 aufgelegte Grundplatte 4 werden mittels einer Halterung 10 die auf dieser eingesetzten Anker 1 abgesenkt und auf der Grundplatte 4 z.B. aufgeklebt. Man kann dann die Halterung 10 für die Anker um eine Stufe heben , wie dies der Doppelpfeil andeutet, und auf die bereits fertig bestückte Grundplatte 4 die nächste Grundplatte auflegen und diese mit Ankern versehen, sodaß sich ein Stapel ergibt, wie er in Fig. 3 dargestellt ist.As shown in Fig. 2, elements can also be created by means of a simple device, which elements can have any length corresponding to the usual commercially available panels and a width which allows easy transportation from the factory to the construction site. On the base plate 4 placed on a table 9, the anchors 1 inserted thereon are lowered by means of a holder 10 and, for example, glued onto the base plate 4. You can then lift the bracket 10 for the anchor by one step, as indicated by the double arrow, and place the next base plate on the already finished base plate 4 and provide it with anchors, so that a stack results, as he is shown in Fig. 3.

Die Fig. 7 und 8 zeigen einen Anker 1 mit einem runden Ankerfuß 2. Der Anker gemäß Fig. 9 und 10 ist mit einer eckigen Fußplatte 11 versehen und der Ankerkopf besteht aus einer beidseitig hinterschnittenen Platte 12. Eine Variante der Fig. 9 und 10 ist ein extrudierter Anker 1, mit gleichem Querschnitt, wobei die Dicke der Platte 12 gleich oder kleiner als die Breite der Fußplatte 11 sein kann. Gemäß einer weiteren Variante (Fig. 11, 12) besteht der Ankerkopf aus zwei sich kreuzenden und hinterschnittenen Platten'13 (Kreuzanker).7 and 8 show an anchor 1 with a round anchor base 2. The anchor according to FIGS. 9 and 10 is provided with an angular base plate 11 and the anchor head consists of a plate 12 undercut on both sides. A variant of FIGS. 9 and 10 is an extruded anchor 1, with the same cross section, wherein the thickness of the plate 12 can be equal to or less than the width of the base plate 11. According to a further variant (FIGS. 11, 12), the anchor head consists of two intersecting and undercut plates 13 (cross anchors).

Wie der Fig. 13 zu entnehmen ist, sind zwei parallele Grundplatten 14, 14' vorgesehen, auf denen im parallelen Reihen und im Abstand pilzförmig ausgebildete Anker 15 vorgesehen sind. Diese Anker sind mit den Grundplatten 14, 14' kraftschlüssig verbunden, sei es durch Kleben, Nageln oder Schrauben 16. Die Anker 15 haben im vorliegenden Fall eine ringförmige Nut 17, in denen die Zugstäbe 18 von beispielsweise X-förmigen Gitterträgern 19 eingreifen und so je zwei einander gegenüberliegende Anker 15 und damit die beiden Grundplatten 14, 14' fest miteinander zusammenhalten.As can be seen from FIG. 13, two parallel base plates 14, 14 'are provided, on which anchors 15 which are mushroom-shaped are provided in parallel rows and at a distance. These anchors are non-positively connected to the base plates 14, 14 ', be it by gluing, nailing or screws 16. In the present case, the anchors 15 have an annular groove 17 in which the tension rods 18 of, for example, X-shaped lattice girders 19 engage and so on hold two opposing anchors 15 and thus the two base plates 14, 14 'together.

Das Zusammenfügen der Schalung kann auf der Baustelle leicht dadurch ausgeführt werden, daß die X-förmigen Gitterträger 19 im Bereich ihrer Zugstäbe 18 etwas gedehnt und über den konisch ausgebildeten Oberteil 20 einrasten.The assembly of the formwork can easily be carried out on the construction site in that the X-shaped lattice girders 19 are stretched somewhat in the area of their tension rods 18 and snap in over the conically shaped upper part 20.

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 große 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. According to the static conditions, the spacing of the rows of anchors can vary and the steel girder itself can be dimensioned as desired. The same anchors can thus accommodate steel girders of different sizes and correspondingly dimensioned in their 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 Grundplatten 14, 14' mit den aufgesetzten Ankern 15 herstellt und vorrätig hält. Je nach Bedarf kann man derartige Grundplatten mit Ausschnitten versehen und auch hinsichtlich ihrer äußeren Abmessungen zurechtschneiden. Die gitterförmigen Träger 19 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.Further effects resulting from the proposal according to the invention can be seen in the fact that only the base plates 14, 14 'with the attached anchors 15 are manufactured and kept in stock in the factory. As required such base plates can be provided with cutouts and also cut to size with regard to their outer dimensions. The grid-shaped supports 19 could already be placed on one of the plates in the factory. This results in a considerable relief in storage, since it is easy to stack prepared standard sizes of base plates. 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.
