Description

Bewehrungskörper für eine Rippendecke aus GußbetonReinforcement body for a ribbed ceiling made of cast concrete
Die Erfindung betrifft einen Bewehrungskörper für eine Rippendecke aus Gußbeton, mit zumindest einem zwischen einer Grundbewehrung und einer Verteilerbewehrung angeordneten, insbesondere aus Schaumstoff bestehenden Verdrängungskörper, der an Hohlräume zur Bildung der Aussteifungsrippen angrenzt und mittels die Grundbewehrung mit der Verteilerbewehrung in wählbarem Abstand zu einer formstabilen Einheit verbindenden Stegdrähten unverrückbar zwischen den Bewehrungen festgelegt ist, wobei in den Rippenhohlräumen zusätzliche Schubbewehrung¬ selemente entsprechend den statischen Erfordernissen der Rip¬ pendecke angeordnet sind.The invention relates to a reinforcement body for a rib ceiling made of cast concrete, with at least one displacement body arranged between a basic reinforcement and a distributor reinforcement, in particular consisting of foam, which adjoins cavities for forming the stiffening ribs and by means of the basic reinforcement with the distributor reinforcement at a selectable distance from a dimensionally stable unit connecting web wires is fixed immovably between the reinforcements, additional shear reinforcement elements being arranged in the rib cavities in accordance with the structural requirements of the ribbed ceiling.
Bei der Herstellung eines solchen Bewehrungskörpers, wie er aus der AT-PS 396 274 bekannt ist, bereitet das Ausformen von Rippenhohlräumen im einteiligen Verdrängungskörper Schwie¬ rigkeiten. Außerdem ist die Handhabung des Bewehrungskörpers mit einer sich über mehrere Verdrängungskörper erstreckende durchgehenden Verteilerbewehrung und Grundbewehrung sehr um- ständlich und beschränkt den Einsatz des Bewehrungskörpers beim Aufbau unterschiedlicher Rippendecken mit Hilfe des Beweh- rungskörpers.In the manufacture of such a reinforcement body, as is known from AT-PS 396 274, the forming of rib cavities in the one-part displacement body causes difficulties. In addition, the handling of the reinforcement body with a continuous distributor reinforcement and basic reinforcement extending over several displacement bodies is very cumbersome and limits the use of the reinforcement body when constructing different ribbed ceilings with the aid of the reinforcement body.
Aufgabe der Erfindung ist es, den Bewehrungskörper derart weiterzubilden, daß er bereits im Herstellerwerk vorgefertigt werden kann, so daß er den Aufbau einer Rippendecke aus mehre¬ ren Bewehrungskörpern an der Baustelle erleichtert und größere Stützweiten ohne Montageunterstellung erlaubt. Der Bewehrungs¬ körper zeichnet sich dadurch aus, daß jeder Verdrängungskörper Teil eines selbständigen Gitterkörpers mit einem Grundbeweh- rungsteil und einer Verteilerbewehrung ist und daß der Gitter¬ körper auf einer Basisbewehrung angeordnet ist, die gemeinsam mit dem Grundbewehrungsteil des Gitterkörpers und Teilen der Schubbewehrungselemente in eine Elementplatte aus Gußbeton eingebettet ist, und wobei auf der Verteilerbewehrung des Gitterkörpers bzw. zumindest einer von mehreren Gitterkörpern ein parallel zu den Rippenhohlräumen verlaufender Betonobergurt mit wählbarer Länge, Breite und Höhe mittig angeordnet ist.The object of the invention is to further develop the reinforcement body in such a way that it can be prefabricated in the manufacturing plant, so that it facilitates the construction of a ribbed ceiling from several reinforcement bodies at the construction site and allows larger spans without the need for assembly. The reinforcement body is characterized in that each displacement body is part of an independent lattice body with a basic reinforcement part and a distribution reinforcement and that the lattice body is arranged on a basic reinforcement, which together with the basic reinforcement part of the lattice body and parts of the shear reinforcement elements into one Element plate made of cast concrete is embedded, and wherein on the distributor reinforcement of the lattice body or at least one of a plurality of lattice bodies, a concrete upper flange running parallel to the rib cavities and having a selectable length, width and height is arranged in the center.
Durch die Erfindung wird erreicht, daß der Bewehrungskör¬ per aus maschinell vorgefertigten Gitterkörpern aufgebaut wer- den kann, deren Anzahl je nach den Erfordernissen gewählt wird, so daß ein modulartiger Aufbau möglich ist. Durch die Verwen¬ dung von vorgefertigten Gitterkörpern wird eine äußerst ratio¬ nelle Herstellung gewährleistet. Gemäß einer bevorzugten Ausführungsform der Erfindung sind die Rippenhohlräume jeweils mit einem auf der Basisbewehrung angeordneten Gitterträger bewehrt, der einen Obergurt, zwei Un¬ tergurte sowie diagonal zwischen dem Obergurt und den Untergur¬ ten zickzackförmig verlaufende und diese miteinander verbin- dende Ausfachungsdrähte aufweist und eine bis zu der Verteiler¬ bewehrung des Gitterkörpers bzw. der Gitterkörper reichende oder kleinere Höhe hat. Auf diese Weise wird auf einfache Weise eine Bewehrung hoher Festigkeit erzielt.It is achieved by the invention that the reinforcement body is constructed from mechanically prefabricated lattice bodies. can, the number of which is chosen depending on the requirements, so that a modular structure is possible. The use of prefabricated lattice bodies ensures extremely rational production. According to a preferred embodiment of the invention, the rib cavities are in each case reinforced with a lattice girder arranged on the base reinforcement, which has an upper chord, two lower chords and diagonal wires between the upper chord and the lower chords that connect them to one another and one to to the distribution reinforcement of the lattice body or the lattice body has sufficient or smaller height. In this way, reinforcement of high strength is easily achieved.
In konstruktiv vorteilhafter Weise besteht die Basisbeweh- rung aus einer Bewehrungsgittermatte, die senkrecht zueinander verlaufende, miteinander verschweißte Längs- und Querdrähte aufweist.In a structurally advantageous manner, the basic reinforcement consists of a reinforcement mesh mat that has longitudinal and transverse wires that are perpendicular to one another and welded to one another.
Nach einem anderen Erfindungsmerkmal ist die Breite der Betonobergurte kleiner als die Breite des jeweiligen Gitterkör- pers, vorzugsweise die Hälfte der Gitterkörperbreite.According to another feature of the invention, the width of the upper concrete belts is smaller than the width of the respective lattice body, preferably half of the lattice body width.
Bei Vorhandensein mehrerer Gitterkörper weist erfindungs¬ gemäß jeder Gitterkörper eine rechteckige Grundfläche auf und die Rippenhohlräume verlaufen parallel zur Längserstreckung der Gitterkörper. Zweckmäßig können alle Schubbewehrungselemente und/oder jeder Gitterkörper mit der Basisbewehrung fest verbunden sein.If there are several lattice bodies, each lattice body according to the invention has a rectangular base area and the rib cavities run parallel to the longitudinal extension of the lattice body. All shear reinforcement elements and / or each lattice body can expediently be firmly connected to the basic reinforcement.
Weitere Merkmale und Vorteile der Erfindung werden nach¬ folgend an einem Ausführungsbeispiel unter Bezugnahme auf die Zeichnung näher erläutert, die einen Querschnitt durch einen Bewehrungskörper nach der Erfindung zeigt.Further features and advantages of the invention are explained in more detail below using an exemplary embodiment with reference to the drawing, which shows a cross section through a reinforcement body according to the invention.
Der Bewehrungskörper weist zwei Gitterkörper 1 mit vor¬ zugsweise rechteckiger Grundfläche auf, die auf einer Basisbe¬ wehrung 2 derart angeordnet sind, daß sie die beiden Gitterkör¬ per 1 seitlich überragt. Die Basisbewehrung 2 besteht vorzugs- weise aus einer Bewehrungsgittermatte aus senkrecht zueinander verlaufenden, miteinander verschweißten Längs- und Querdrähten, wobei die Drahtdurchmesser sowie die Längsdraht- und Querdraht- abstände entsprechend den statischen Anforderungen an den Be- wehrungskörper gewählt sind. Die Länge der Basisbewehrung 2 stimmt mit der Länge der Gitterkörper 1 überein.The reinforcement body has two lattice bodies 1 with a preferably rectangular base area, which are arranged on a base reinforcement 2 in such a way that they laterally project beyond the two lattice bodies 1. The basic reinforcement 2 preferably consists of a reinforcing mesh mat made of perpendicular and mutually welded longitudinal and transverse wires, the wire diameter as well as the longitudinal wire and transverse wire spacing corresponding to the static requirements of the loading reinforcement elements 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 ab- schließen. Der Grundbewehrungsteil 3 und die Verteilerbewehrung 4 bestehen aus Bewehrungsgittermatten, die jeweils aus senk¬ recht zueinander verlaufenden, miteinander verschweißten Längs¬ und Querdrähten gebildet sind, wobei die Abmessungen der Beweh¬ rungsgittermatten entsprechend den statischen Anforderung an den Bewehrungskörper gewählt sind.Each lattice 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 distributor reinforcement 4 consist of reinforcement mesh mats, each of which is formed from longitudinal and transverse wires that are welded to one another and welded to one another, the dimensions of the reinforcement mesh mats being selected in accordance with the structural requirements for the reinforcement body.
Der Grundbewehrungsteil 3 und die Verteilerbewehrung 4 sind miteinander durch Stegdrähte 5 verbunden, die zwischen den entsprechend eingefluchteten Längsdrähten des Grundbewehrungs- teiles 3 und der Verteilerbewehrung 4 verlaufen und mit diesen verschweißt sind. Eine Verbindung entsprechend eingefluchteter Querdrähte des Grundbewehrungsteiles 3 und der Verteilerbeweh¬ rung 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 Beweh¬ rungskörpers herzustellenden Deckenplatte anpaßbar.The basic reinforcement part 3 and the distributor reinforcement 4 are connected to one another by web wires 5, which run between the correspondingly aligned longitudinal wires of the basic reinforcement part 3 and the distributor reinforcement 4 and are welded to them. A connection of appropriately aligned transverse wires of the basic reinforcement part 3 and the distributor reinforcement 4 with the aid of the web wires 5 is also possible within the scope of the invention. The distance between the basic reinforcement part 3 and the distributor reinforcement 4 and thus the length of the web wires 5 can be freely selected and can be adapted to the height of the ceiling slab to be produced using the reinforcement body.
Zwischen dem Grundbewehrungsteil 3 und der Verteilerbeweh¬ rung 4 ist mit vorbestimmte Abstand zu diesen ein Verdrän¬ gungskörper 6 vorbestimmter Höhe angeordnet, der zweckmäßig aus Leichtmaterial, beispielsweise Styropor besteht, und es ermög¬ licht, in der herzustellenden Rippendecke Beton einzusparen und damit ihr Gewicht zu verringern.Arranged between the basic reinforcement part 3 and the distributor reinforcement 4 at a predetermined distance from them is a displacement body 6 of a predetermined height, which expediently consists of light material, for example polystyrene, and makes it possible to save concrete in the ribbed roof to be produced and thus to save its weight to reduce.
Die Stegdrähte 5 durchdringen den Verdrängungskörper 6 und sind abwechselnd gegensinnig schräg zueinander in Form eines Fachwerkes angeordnet. Durch diese Anordnung sind die Steg¬ drähte 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 Schub- kräfte aufzunehmen.The web wires 5 penetrate the displacement body 6 and are alternately arranged in opposite directions at an angle to one another in the form of a framework. This arrangement enables the web wires 5 to fix the displacement body 6 precisely in its position in the lattice body 1 and also to absorb shear forces acting on the lattice body 1 parallel and perpendicular to the longitudinal wires of the basic reinforcement part 3 and the distributor reinforcement 4.
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 re¬ lativ zu dem Grundbewehrungsteil 3 und der Verteilerbewehrung 4 gewährleisten und in der Lage sind, Schubkräfte aufzunehmen. Es ist beispielsweise möglich, alle Stegdrähte zwischen zwei zuge¬ ordnete Längsdrähten des Grundbewehrungsteiles und der Vertei¬ lerbewehrung gleichsinnig schräg anzuordnen, und alle Steg- drahte zwischen benachbarten, zugeordneten Längsdrähten eben¬ falls gleichsinnig schräg, jedoch mit entgegengesetztem Rich¬ tungssinn zur erstgenannten Stegdrahtschar anzuordnen, so daß eine fischgrätenartige Struktur entsteht. Dies gilt in gleicher Weise, falls die Stegdrähte zwischen zugeordneten Querdrähten verlaufen.Within the scope of the invention, there are also other possibilities for arranging the web wires 5 in the lattice body 1, which have an immovable and fixed position of the displacement body 6 relative to the basic reinforcement part 3 and the distributor reinforcement 4 ensure and are able to absorb thrust. It is possible, for example, to arrange all the bridge wires between two assigned longitudinal wires of the basic reinforcement part and the distribution reinforcement in the same direction, and to arrange all bridge wires between adjacent, assigned longitudinal wires also in the same direction, but with the opposite direction to the first mentioned bridge wire family , so that a herringbone-like structure is created. This applies in the same way if the bridge wires run between assigned cross wires.
Durch die Ausbildung des Grundbewehrungsteiles 3 und der Verteilerbewehrung 4 als Bewehrungsmatten, sowie der Stegdrähte 5 als Schubbewehrungselemente entsteht ein formstabiler Gitter¬ körper 1, der in der Lage ist, entsprechende Kräfte aufzunehmen und in die Basisbewehrung 2 weiterzuleiten.The design of the basic reinforcement part 3 and the distributor reinforcement 4 as reinforcement mats, as well as the web wires 5 as shear reinforcement elements, results in a dimensionally stable lattice body 1 which is capable of absorbing corresponding forces and transmitting them to the basic reinforcement 2.
Die Gitterkörper 1 werden auf der Basisbewehrung 2 mit seitlichem Abstand zueinander derart angeordnet, daß ein zen¬ traler, parallel zur Längserstreckung der Gitterkörper 1 ver¬ laufender Rippenhohlraum 7 mit vorbestimmter Breite entsteht. Durch den seitlichen Überstand der Basisbewehrung 2 über die Gitterkörper 1 hinaus werden seitliche, parallel zur Längser¬ streckung der Gitterkörper 1 verlaufende Rippenhohlräume 7' ge¬ bildet. Die Rippenhohlräume 7,7' werden bei der Verwendung des Bewehrungskörpers zur Herstellung einer Rippendecke mit Ortbe- ton 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 ge¬ stellt werden. Die Breite der seitlichen Überstände und damit die Breite der seitlichen Rippenhohlräume 7' wird zusätzlich dadurch bestimmt, daß die Fuge zwischen aneinanderstoßenden Be¬ wehrungskörpern mit einer Fugenbewehrungsmatte überdeckt werden kann, die erst nachträglich bei Montage der Bewehrungskörper auf der Baustelle einzulegen ist. Zur Bewehrung der Aussteifungsrippen sind im zentralen Rippenhohlraum 7 sowie in den beiden Rippenhohlräumen 7' ein zentraler Gitterträger 8 sowie jeweils ein seitlicher Gitter¬ träger 8' angeordnet, wobei alle Gitterträger 8, 8' auf der Ba¬ sisbewehrung 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 Aus- fachungsdrähte 11 sind entsprechend den statischen Anforderun¬ gen an die Bewehrung der Rippenhohlräume 7, 7' wählbar.The lattice bodies 1 are arranged on the base reinforcement 2 with a lateral spacing from one another in such a way that a central rib cavity 7 with a predetermined width, parallel to the longitudinal extension of the lattice bodies 1, is created. The lateral protrusion of the basic reinforcement 2 beyond the lattice body 1 also results in lateral rib cavities 7 ′ running parallel to the longitudinal extension of the lattice body 1. The rib cavities 7, 7 'are filled with in-situ concrete when the reinforcement body is used to produce a rib ceiling and thus form the stiffening ribs of the rib ceiling. The width of the rib cavities 7, 7 'must therefore be selected in accordance with the static requirements that are placed on the stiffening ribs of the rib ceiling to be produced. The width of the lateral protrusions and thus the width of the lateral rib cavities 7 'is additionally determined by the fact that the joint between abutting reinforcement bodies can be covered with a joint reinforcement mat which is only to be inserted subsequently when the reinforcement bodies are installed on the construction site. To reinforce the stiffening ribs, a central lattice girder 8 and a lateral lattice girder 8 'are arranged in the central rib cavity 7 and in the two rib cavities 7', all lattice girders 8, 8 'standing on the base reinforcement 2. Each lattice girder 8, 8 'consists of an upper chord 9, two lower chords 10 and diagonal between the upper chord 9 and the lower chords 10 extending and interconnecting infill wires 11. The dimensions of the upper chord 9, the lower chords 10 and the infill wires 11 are in accordance with the static requirements for the Reinforcement of the rib cavities 7, 7 'can be selected.
Die Höhe der Gitterträger 8, 8' wird derart gewählt, daß die Obergurte 9 aller Gitterträger 8, 8' jeweils mit den Ver¬ teilerbewehrungen 4 der Gitterkörper 1 fluchten; sie kann je- doch auch kleiner sein.The height of the lattice girders 8, 8 'is selected such that the top chords 9 of all lattice girders 8, 8' are each aligned with the distribution reinforcements 4 of the lattice body 1; however, it can also be smaller.
Im Rahmen der Erfindung ist es möglich, die Gitterträger 8, 8' insbesondere im Bereich der Untergurte 10 mit Zusatzbe¬ wehrungselementen, beispielsweise in Form von Einzelstäben zu verstärken. Die Gitterträger 8, 8' sowie die Gitterkörper 1 stehen je¬ weils 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 Grundbeweh¬ rungen 3 der Gitterkörper 1 können mit Hilfe von geeigneten Be- festigungselementen, wie z.B. Klammern oder Rödeldraht, mit den entsprechenden Drähten der Basisbewehrung 2 fest verbunden wer¬ den, so daß ein Verrutschen der Gitterträger 8, 8' und der Git¬ terkörper 1 bei der weiteren Bearbeitung des Bewehrungskörpers vermieden wird. Der Bewehrungskörper ist mit einer Elementplatte 12 aus Beton versehen, wobei die Betonschicht die Basisbewehrung 2, die Grundbewehrungen 3 der Gitterkörper 1 und die Untergurte 10 der Gitterträger 8, 8' vollständig einbetten muß.Within the scope of the invention it is possible to reinforce 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. The lattice girders 8, 8 'and the lattice body 1 each stand on the basic reinforcement 2 and are only shown at a distance in the figure for reasons of simplicity. The lower chords 10 of the lattice girders 8, 8 'and the basic reinforcements 3 of the lattice bodies 1 can be fastened with the aid of suitable fastening elements, such as e.g. Brackets or solder wire are firmly connected to the corresponding wires of the basic reinforcement 2, so that slipping of the lattice girders 8, 8 'and the lattice body 1 is avoided during further processing of the reinforcement body. The reinforcement body is provided with an element plate 12 made of concrete, the concrete layer having to completely embed the basic reinforcement 2, the basic reinforcements 3 of the lattice body 1 and the lower chords 10 of the lattice girders 8, 8 '.
Bei der Herstellung des Bewehrungskörpers werden üblicher- weise 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 Gitterträ¬ ger 8, 8' hineinzudrücken.When manufacturing the reinforcement body, the base reinforcement 2, the lattice body 1 and the lattice girders 8, 8 'are usually first positioned in a formwork frame and then the element plate 12 is cast. Within the scope of the invention, however, it is also possible to first pour the element plate 12 from flow concrete and in a subsequent work step to press the basic reinforcement 2, the basic reinforcements 3 of the lattice body 1 and the lattice girders 8, 8 'into the still soft flow concrete.
Auf jedem Gitterkörper 1 ist ein parallel zu den Rippen¬ hohlräumen 7, 7' verlaufender Betonobergurt 13 mittig ange- bracht, 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 Montageun- terstellungen.On each lattice body 1 there is a concrete upper flange 13 running parallel to the rib cavities 7, 7 '. brings, the length, width and height are freely selectable, the width is smaller than the width of the grid body 1 and is expediently half the width of the grid body 1. The concrete upper chords 13 additionally stiffen the reinforcement body and, when building a ribbed ceiling with the aid of the reinforcement body according to the invention, enable a substantial increase in the assembly support width and thus a saving in assembly supports.
Zur Herstellung des Betonobergurtes 13 werden seitliche Schalungsleisten 14 sowie nicht dargestellte Schalungsleisten jeweils an den Stirnseiten auf der Verteilerbewehrung 4 ange¬ ordnet. 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 Scha¬ lungsleisten 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, bei¬ spielsweise mittels Rödeldraht, verbunden sind. In diesem Fall kann ein geringfügiges seitliches Herausfließen des 3etons bei der Herstellung des Betonobergurtes 13 im Bereich zwischen der Verteilerbewehrung 4 und dem Verdrängungskörper 6 nicht verhin- dert 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 concrete upper chord 13, lateral formwork strips 14 and formwork strips (not shown) are arranged on the end faces of the distributor reinforcement 4. The formwork strips 14 are comb-like, so that they reach into the mesh of the distributor reinforcement 4 and are fixed in position by the distributor reinforcement 4. The formwork strips 14 extend to the upper cover surface of the displacer 6 and thus limit the concrete upper flange 13 laterally. The same applies to the formwork strips, not shown, on the end faces. Within the scope of the invention, however, it is also possible to use straight formwork strips which rest only on the distributor reinforcement 4 and are connected to the latter, for example by means of a wire rod. In this case, it is not possible to prevent the 3eton from flowing out slightly to the side during the production of the concrete upper flange 13 in the area between the distributor reinforcement 4 and the displacement body 6. However, this flowing out is not critical and is kept within limits by the preferably small distance of 13 to 20 mm between the distributor reinforcement 4 and the displacement body 6.
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 Bewehrungs¬ körpern kann im Rahmen der Erfindung nur ein einziger Verdrän¬ gungskörper bzw. Gitterkörper Verwendung finden, wobei in die- se Fall der zentrale Rippenhohlraum und damit auch der zentra¬ le Gitterträger entfallen und nur an den seitlichen Rändern des Gitterkörpers Rippenhohlräume entstehen. Ein sehr breiter Be¬ wehrungskörper 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 Git¬ terkörper mit einem Betonöbergurt -zu versehen; es sollte jedoch gewäl.-leistet sein, daß die Verteilung der Betonobergurte über den gesamten Bewehrungskörper symmetrisch ist. Die Rippenhohl¬ räume können auch durch andere Schubbewehrungselemente, wie beispielsweise Schubbewehrungsbügel, bewehrt werden. Die Basis¬ bewehrung kann schließlich im Rahmen der Erfindung auch aus einzelnen entsprechend angeordneten Bewehrungsstäben bestehen. It goes without saying that the described exemplary embodiment can be modified in various ways within the scope of the general inventive concept, in particular with regard to the number of lattice bodies per reinforcement body. In the case of narrow reinforcement bodies, only a single displacement body or lattice body can be used within the scope of the invention, in which case the central rib cavity and thus also the central lattice girder are omitted and rib cavities only arise on the lateral edges of the lattice body . Within the scope of the invention, a very wide reinforcement body can have three or more lattice bodies, each between adjacent ones Lattice bodies a central rib cavity is predetermined, which is reinforced with a lattice girder. In this case it is also possible within the scope of the invention not to provide each grille body with a concrete upper belt; however, it should be ensured that the distribution of the concrete top chords is symmetrical over the entire reinforcement body. The rib cavities can also be reinforced by other shear reinforcement elements, such as shear reinforcement stirrups. Finally, the basic reinforcement can also consist of individual appropriately arranged reinforcement bars within the scope of the invention.
