Der Bewehrungskörper weist zwei Gitterkörper 1 mit vorzugsweise rechteckiger Grundfläche auf, die auf einer Basisbewehrung 2 derart angeordnet sind, daß sie die beiden Gitterkörper 1 seitlich überragt. Die Basisbewehrung 2 besteht vorzugsweise aus einer Bewehrungsgittermatte aus senkrecht zueinander verlaufenden, miteinander verschweißten Längs- und Querdrähten, wobei die Drahtdurchmesser sowie die Längsdraht- und Querdrahtabstände entsprechend den statischen Anforderungen an den Bewehrungskörper gewählt sind. Die Länge der Basisbewehrung 2 stimmt mit der Länge der Gitterkörper 1 überein.The reinforcement body preferably has two lattice bodies 1 rectangular base on the base reinforcement 2 are arranged such that they the two lattice bodies 1 protrudes laterally. The basic reinforcement 2 preferably consists from a reinforcement mesh mat perpendicular to each other running, welded longitudinal and transverse wires, where the wire diameter as well as the line wire and cross wire distances according to the static requirements for the reinforcement body are selected. The length of the basic reinforcement 2 corresponds to the length of the lattice body 1.

Jeder Gitterkörper 1 hat einen Grundbewehrungsteil 3 und eine Verteilerbewehrung 4, die zweckmäßig allseitig bündig abschließen. Der Grundbewehrungsteil 3 und die Verteilerbewehrung 4 bestehen aus Bewehrungsgittermatten, die jeweils aus senkrecht zueinander verlaufenden, miteinander verschweißten Längs- und Querdrähten gebildet sind, wobei die Abmessungen der Bewehrungsgittermatten entsprechend den statischen Anforderung an den Bewehrungskörper gewählt sind.Each grid body 1 has a basic reinforcement part 3 and a distributor reinforcement 4, which are expediently flush on all sides. The basic reinforcement part 3 and the distribution reinforcement 4 consist of reinforcement mesh, each consisting of vertical mutually extending, welded longitudinal and cross wires are formed, the dimensions of the reinforcement mesh according to the static requirement the reinforcement body are selected.

Der Grundbewehrungsteil 3 und die Verteilerbewehrung 4 sind miteinander durch Stegdrähte 5 verbunden, die zwischen den entsprechend eingefluchteten Längsdrähten des Grundbewehrungsteiles 3 und der Verteilerbewehrung 4 verlaufen und mit diesen verschweißt sind. Eine Verbindung entsprechend eingefluchteter Querdrähte des Grundbewehrungsteiles 3 und der Verteilerbewehrung 4 mit Hilfe der Stegdrähte 5 ist im Rahmen der Erfindung ebenfalls möglich. Der Abstand des Grundbewehrungsteiles 3 zur Verteilerbewehrung 4 und damit die Länge der Stegdrähte 5 ist frei wählbar und jeweils an die Höhe der mit Hilfe des Bewehrungskörpers herzustellenden Deckenplatte anpaßbar.The basic reinforcement part 3 and the distribution reinforcement 4 are connected to each other by web wires 5, which between the correspondingly aligned longitudinal wires of the basic reinforcement part 3 and the distribution reinforcement 4 run and with these are welded. A connection correspondingly aligned Cross wires of the basic reinforcement part 3 and the distribution reinforcement 4 with the help of the bridge wires 5 is within the scope of the invention also possible. The distance of the basic reinforcement part 3 to Distribution reinforcement 4 and thus the length of the web wires 5 freely selectable and each at the height of the with the help of the reinforcement body customizable ceiling plate.

Zwischen dem Grundbewehrungsteil 3 und der Verteilerbewehrung 4 ist mit vorbestimmtem Abstand zu diesen ein Verdrängungskörper 6 vorbestimmter Höhe angeordnet, der zweckmäßig aus Leichtmaterial, beispielsweise Styropor besteht, und es ermöglicht, in der herzustellenden Rippendecke Beton einzusparen und damit ihr Gewicht zu verringern.Between the basic reinforcement part 3 and the distribution reinforcement 4 is a displacement body with a predetermined distance from them 6 predetermined height arranged, the expedient Light material, such as polystyrene, and it allows save concrete in the ribbed ceiling to be produced and thereby reducing their weight.

Die Stegdrähte 5 durchdringen den Verdrängungskörper 6 und sind abwechselnd gegensinnig schräg zueinander in Form eines Fachwerkes angeordnet. Durch diese Anordnung sind die Stegdrähte 5 befähigt, den Verdrängungskörper 6 in seiner Lage im Gitterkörper 1 genau zu fixieren und außerdem parallel und senkrecht zu den Längsdrähten des Grundbewehrungsteiles 3 und der Verteilerbewehrung 4 auf den Gitterkörper 1 wirkende Schubkräfte aufzunehmen.The web wires 5 penetrate the displacement body 6 and are alternately diagonally opposite to each other in the form of a Truss arranged. With this arrangement, the bridge wires are 5 enables the displacer 6 in its position in To fix grid body 1 exactly and also parallel and perpendicular to the longitudinal wires of the basic reinforcement part 3 and the shear reinforcement 4 acting on the lattice body 1 to record.

Im Rahmen der Erfindung sind auch andere Möglichkeiten zur Anordnung der Stegdrähte 5 im Gitterkörper 1 gegeben, die eine unverrückbare und ortsfeste Lage des Verdrängungskörpers 6 relativ zu dem Grundbewehrungsteil 3 und der Verteilerbewehrung 4 gewährleisten und in der Lage sind, Schubkräfte aufzunehmen. Es ist beispielsweise möglich, alle Stegdrähte zwischen zwei zugeordneten Längsdrähten des Grundbewehrungsteiles und der Verteilerbewehrung gleichsinnig schräg anzuordnen, und alle Stegdrähte zwischen benachbarten, zugeordneten Längsdrähten ebenfalls gleichsinnig schräg, jedoch mit entgegengesetztem Richtungssinn zur erstgenannten Stegdrahtschar anzuordnen, so daß eine fischgrätenartige Struktur entsteht. Dies gilt in gleicher Weise, falls die Stegdrähte zwischen zugeordneten Querdrähten verlaufen.Other possibilities are also within the scope of the invention Arrangement of the web wires 5 given in the lattice body 1, the one immovable and fixed position of the displacer 6 relative to the basic reinforcement part 3 and the distribution reinforcement 4 ensure and are able to absorb thrust. It For example, it is possible to assign all the bridge wires between two Longitudinal wires of the basic reinforcement part and the distribution reinforcement to be arranged diagonally in the same direction, and all the bridge wires between adjacent, assigned longitudinal wires as well in the same direction, but with the opposite direction to arrange the first-mentioned web wire coulter, so that a herringbone-like structure is created. This applies equally Way, if the land wires between associated cross wires run.

Durch die Ausbildung des Grundbewehrungsteiles 3 und der Verteilerbewehrung 4 als Bewehrungsmatten, sowie der Stegdrähte 5 als Schubbewehrungselemente entsteht ein formstabiler Gitterkörper 1, der in der Lage ist, entsprechende Kräfte aufzunehmen und in die Basisbewehrung 2 weiterzuleiten.By designing the basic reinforcement part 3 and Distribution reinforcement 4 as reinforcement mesh, as well as the web wires 5 A dimensionally stable lattice structure is created as shear reinforcement elements 1, which is able to absorb appropriate forces and forward it to basic reinforcement 2.

Die Gitterkörper 1 werden auf der Basisbewehrung 2 mit seitlichem Abstand zueinander derart angeordnet, daß ein zentraler, parallel zur Längserstreckung der Gitterkörper 1 verlaufender Rippenhohlraum 7 mit vorbestimmter Breite entsteht. Durch den seitlichen Überstand der Basisbewehrung 2 über die Gitterkörper 1 hinaus werden seitliche, parallel zur Längserstreckung der Gitterkörper 1 verlaufende Rippenhohlräume 7' gebildet. Die Rippenhohlräume 7,7' werden bei der Verwendung des Bewehrungskörpers zur Herstellung einer Rippendecke mit Ortbeton ausgegossen und bilden somit die Aussteifungsrippen der Rippendecke. Die Breite der Rippenhohlräume 7, 7' muß daher entsprechend den statischen Anforderungen gewählt werden, die an die Aussteifungsrippen der herzustellenden Rippendecke gestellt werden. Die Breite der seitlichen Überstände und damit die Breite der seitlichen Rippenhohlräume 7' wird zusätzlich dadurch bestimmt, daß die Fuge zwischen aneinanderstoßenden Bewehrungskörpern mit einer Fugenbewehrungsmatte überdeckt werden kann, die erst nachträglich bei Montage der Bewehrungskörper auf der Baustelle einzulegen ist.The lattice body 1 is based on the basic reinforcement 2 lateral distance from each other so that a central, parallel to the longitudinal extent of the lattice body 1 Rib cavity 7 with a predetermined width is formed. Due to the lateral protrusion of the basic reinforcement 2 over the Lattice body 1 are lateral, parallel to the longitudinal extent the grid body 1 extending rib cavities 7 'are formed. The rib cavities 7,7 'are when using the Reinforcement body for the production of a rib ceiling with in-situ concrete poured out and thus form the stiffening ribs of the Rib blanket. The width of the rib cavities 7, 7 'must therefore be chosen according to the static requirements that placed on the stiffening ribs of the rib ceiling to be produced become. The width of the side protrusions and thus the width of the lateral rib cavities 7 'becomes additional determined by the fact that the joint between abutting reinforcement bodies be covered with a joint reinforcement mat that can only be added later when the reinforcement body is installed is to be inserted at the construction site.

Zur Bewehrung der Aussteifungsrippen sind im zentralen Rippenhohlraum 7 sowie in den beiden Rippenhohlräumen 7' ein zentraler Gitterträger 8 sowie jeweils ein seitlicher Gitterträaer 8' angeordnet, wobei alle Gitterträger 8, 8' auf der Basisbewehrung 2 stehen. Jeder Gitterträger 8, 8' besteht aus einem Obergurt 9, zwei Untergurten 10 und diagonal zwischen dem Obergurt 9 und den Untergurten 10 zickzackförmig verlaufenden und diese miteinander verbindenden Ausfachungsdrähten 11. Die Abmessungen des Obergurtes 9, der Untergurte 10 sowie der Ausfachungsdrähte 11 sind entsprechend den statischen Anforderungen an die Bewehrung der Rippenhohlräume 7, 7' wählbar.Reinforcement of the stiffening ribs are in the central Rib cavity 7 and in the two rib cavities 7 ' central lattice girder 8 and a lateral lattice girder 8 'arranged, with all lattice girders 8, 8' on the base reinforcement 2 stand. Each lattice girder 8, 8 'consists of an upper chord 9, two lower chords 10 and diagonally between the Upper chord 9 and the lower chords 10 running zigzag and these interconnecting infill wires 11. Die Dimensions of the upper chord 9, the lower chords 10 and the infill wires 11 are according to the static requirements selectable for the reinforcement of the rib cavities 7, 7 '.

Die Höhe der Gitterträger 8, 8' wird derart gewählt, daß die Obergurte 9 aller Gitterträger 8, 8' jeweils mit den Verteilerbewehrungen 4 der Gitterkörper 1 fluchten; sie kann jedoch auch kleiner sein.The height of the lattice girders 8, 8 'is chosen such that the top chords 9 of all lattice girders 8, 8 'each with the distributor reinforcements 4 the grid body 1 are aligned; however, it can also be smaller.

Im Rahmen der Erfindung ist es möglich, die Gitterträger 8, 8' insbesondere im Bereich der Untergurte 10 mit Zusatzbewehrungselementen, beispielsweise in Form von Einzelstäben zu verstärken.In the context of the invention, it is possible to use the lattice girders 8, 8 ', in particular in the area of the lower chords 10 with additional reinforcement elements, for example in the form of individual bars reinforce.

Die Gitterträger 8, 8' sowie die Gitterkörper 1 stehen jeweils auf der Basisbewehrung 2 und sind nur aus Gründen der einfacheren Darstellung in der Figur mit Abstand eingezeichnet. Die Untergurte 10 der Gitterträger 8, 8' sowie die Grundbewehrungen 3 der Gitterkörper 1 können mit Hilfe von geeigneten Befestigungselementen, wie z.B. Klammern oder Rödeldraht, mit den entsprechenden Drähten der Basisbewehrung 2 fest verbunden werden, so daß ein Verrutschen der Gitterträger 8, 8' und der Gitterkörper 1 bei der weiteren Bearbeitung des Bewehrungskörpers vermieden wird.The lattice girders 8, 8 'and the lattice body 1 each stand on the basic reinforcement 2 and are only for the sake of simpler representation shown in the figure at a distance. The lower chords 10 of the lattice girders 8, 8 'and the basic reinforcements 3 of the lattice body 1 can be fastened with the aid of suitable fastening elements, such as. Brackets or wire, with which corresponding wires of the basic reinforcement 2 are firmly connected, so that slipping of the lattice girders 8, 8 'and the lattice body 1 during further processing of the reinforcement body is avoided.

Bei der Herstellung des Bewehrungskörpers werden üblicherweise zunächst die Basisbewehrung 2, die Gitterkörper 1 sowie die Gitterträger 8, 8' in einem Schalungsrahmen positioniert und anschließend wird die Elementplatte 12 gegossen. Im Rahmen der Erfindung ist es jedoch auch möglich, die Elementplatte 12 zunächst aus Fließbeton zu gießen und in einem nachfolgenden Arbeitsgang in den noch weichen Fließbeton die Basisbewehrung 2, die Grundbewehrungen 3 der Gitterkörper 1 und die Gitterträger 8, 8' hineinzudrücken.When manufacturing the reinforcement body are usually first the basic reinforcement 2, the lattice body 1 and the lattice girders 8, 8 'positioned in a formwork frame and then the element plate 12 is cast. As part of However, according to the invention it is also possible to use the element plate 12 First pour from flow concrete and in a subsequent one Work in the still soft flow concrete the basic reinforcement 2, the basic reinforcements 3 of the lattice body 1 and the lattice girders 8, 8 '.

Auf jedem Gitterkörper 1 ist ein parallel zu den Rippenhohlräumen 7, 7' verlaufender Betonobergurt 13 mittig angebracht, dessen Länge, Breite und Höhe frei wählbar sind, wobei die Breite kleiner als die Breite des Gitterkörpers 1 ist und zweckmäßig die Hälfte der Breite des Gitterkörpers 1 beträgt. Die Betonobergurte 13 steifen den Bewehrungskörper zusätzlich aus und ermöglichen beim Aufbau einer Rippendecke mit Hilfe des Bewehrungskörpers nach der Erfindung eine wesentliche Erhöhung der Montagestützweite und damit eine Einsparung an Montageunterstellungen.On each lattice body 1 there is a parallel to the rib cavities 7, 7 'running concrete upper flange 13 attached in the middle, whose length, width and height are freely selectable, whereby the width is smaller than the width of the grid body 1 and expediently half the width of the grid body 1. The concrete upper chords 13 additionally stiffen the reinforcement body and allow when building a ribbed ceiling with the help of Reinforcement body according to the invention a substantial increase the assembly support span and thus a saving on assembly support.

Zur Herstellung des Betonobergurtes 13 werden seitliche Schalungsleisten 14 sowie nicht dargestellte Schalungsleisten jeweils an den Stirnseiten auf der Verteilerbewehrung 4 angeordnet. Die Schalungsleisten 14 sind kammartig ausgebildet, so daß sie in die Maschen der Verteilerbewehrung 4 greifen und durch die Verteilerbewehrung 4 in ihrer Lage fixiert werden. Die Schalungsleisten 14 reichen bis zur oberen Deckfläche des Verdrängungskörpers 6 und begrenzen damit den Betonobergurt 13 seitlich. Das gleiche gilt für die nicht dargestellten Schalungsleisten an den Stirnseiten. Im Rahmen der Erfindung ist es jedoch auch möglich, gerade Schalungsleisten zu verwenden, die nur auf der Verteilerbewehrung 4 aufliegen und mit dieser, beispielsweise mittels Rödeldraht, verbunden sind. In diesem Fall kann ein geringfügiges seitliches Herausfließen des Betons bei der Herstellung des Betonobergurtes 13 im Bereich zwischen der Verteilerbewehrung 4 und dem Verdrängungskörper 6 nicht verhindert werden. Dieses Herausfließen ist jedoch nicht kritisch, und wird durch den vorzugsweise geringen Abstand 13 bis 20 mm zwischen der Verteilerbewehrung 4 und dem Verdrängungskörper 6 in Grenzen gehalten.To produce the upper concrete belt 13 are lateral Formwork strips 14 and formwork strips, not shown each arranged on the end faces on the distributor reinforcement 4. The formwork strips 14 are comb-like, so that they reach into the mesh of the distribution reinforcement 4 and be fixed in position by the distributor reinforcement 4. The formwork strips 14 extend to the upper surface of the Displacement body 6 and thus limit the upper concrete flange 13 laterally. The same applies to the formwork strips, not shown on the end faces. It is within the scope of the invention however, it is also possible to use straight shuttering strips that just rest on the distribution reinforcement 4 and with this, for example are connected by wire. In this case can cause the concrete to flow out slightly to the side the manufacture of the upper concrete belt 13 in the area between the Distribution reinforcement 4 and the displacement body 6 are not prevented become. However, this flowing out is not critical and is due to the preferably small distance 13 to 20 mm between the distributor reinforcement 4 and the displacement body 6 kept within limits.

Es versteht sich, daß das geschilderte Ausführungsbeispiel im Rahmen des allgemeinen Erfindungsgedankens verschiedentlich abgewandelt werden kann, insbesondere hinsichtlich der Anzahl der Gitterkörper je Bewehrungskörper. Bei schmalen Bewehrungskörpern kann im Rahmen der Erfindung nur ein einziger Verdrängungskörper bzw. Gitterkörper Verwendung finden, wobei in diesem Fall der zentrale Rippenhohlraum und damit auch der zentrale Gitterträger entfallen und nur an den seitlichen Rändern des Gitterkörpers Rippenhohlräume entstehen. Ein sehr breiter Bewehrungskörper kann im Rahmen der Erfindung drei oder auch mehr Gitterkörper aufweisen, wobei jeweils zwischen benachbarten Gitterkörpern ein zentraler Rippenhohlraum vorgegeben ist, der jeweils mit einem Gitterträger bewehrt ist. In diesem Fall ist es im Rahmen der Erfindung außerdem möglich, nicht jeden Gitterkörper mit einem Betonobergurt zu versehen; es sollte jedoch gewährleistet sein, daß die Verteilung der Betonobergurte über den gesamten Bewehrungskörper symmetrisch ist. Die Rippenhohlräume können auch durch andere Schubbewehrungselemente, wie beispielsweise Schubbewehrungsbügel, bewehrt werden. Die Basisbewehrung kann schließlich im Rahmen der Erfindung auch aus einzelnen entsprechend angeordneten Bewehrungsstäben bestehen.It is understood that the described embodiment various within the scope of the general inventive concept can be modified, especially with regard to the number the grid body per reinforcement body. With narrow reinforcement bodies can only one displacement body within the scope of the invention or grid body are used, in this Case the central rib cavity and thus also the central one Lattice girders are omitted and only on the side edges of the Lattice body rib cavities arise. A very wide reinforcement body can three or more within the scope of the invention Have grid bodies, each between adjacent Lattice bodies a central rib cavity is given, the is reinforced with a lattice girder. In this case it is also possible within the scope of the invention not every lattice body to be provided with a concrete upper belt; however, it should be sure that the distribution of the concrete top chord over the entire reinforcement body is symmetrical. The rib cavities can also by other shear reinforcement elements, such as for example shear reinforcement stirrups. The basic reinforcement can finally also within the scope of the invention individual correspondingly arranged reinforcing bars.
