Abstract

A concrete steel mesh (1) for large-surface reinforced concrete buildings consists of reinforcing bars (2) and positioning wires (3, 3') thinner than the reinforcing bars that extend perpendicularly thereto and are welded to the reinforcing bars. In order to form standard reinforcing elements that may be part of a storage programme, the concrete steel mesh has at least 1000 and maximum 1200 mm width, from 4 to 9 m length, maximum seven reinforcing bars with a ribbed surface and 6 to 16 mm diameter arranged in a plane parallel to each other at 200 mm distance from each other, and several positioning wires arranged at 400 to 1200 mm distance from each other. The positioning wires adjacent to the free ends of the reinforcing bars are located from 200 to 500 mm away from the ends of the reinforcing bars.

Description

Betonstahlstreifen für flächenartige Stahlbetonkonstruktionen Reinforcing steel strips for sheet-like reinforced concrete structures
Die Erfindung betrifft einen Betonstahlstreifen für flä¬ chenartige Stahlbetonkonstruktionen, bestehend aus mehreren zu- einander parallelen, mit gegenseitigem Abstand in einer Ebene angeordneten Bewehrungsstäben und mehreren senkrecht zu den Be¬ wehrungsstäben verlaufenden, schwächer als diese ausgebildeten und mit diesen verschweißten Positionsdrähten.The invention relates to a reinforcing steel strip for sheet-like reinforced concrete structures, consisting of a plurality of reinforcing bars that are parallel to one another, spaced apart in a plane, and a plurality of positioning wires that run perpendicular to the reinforcing bars and are weaker than these and welded to them.
Es ist bekannt, die Bewehrung von flächenartigen Stahlbe- tonkonstruktionen mit Hilfe von einzeln zu verlegenden Beweh¬ rungsstäben, mit Hilfe von vorgefertigten Bewehrungsmatten, so¬ genannten Lagermatten, die entsprechend angepaßt und daher zugeschnitten werden müssen, oder mit Hilfe von vorgefertigten, an die statischen und räumlichen Anforderungen maßgerecht an- gepaßten Bewehrungsmatten, sogenannten Listenmatten, auszufüh¬ ren. Der Nachteil der Stabbewehrung besteht im großen Arbeits¬ aufwand beim Verlegen der Bewehrungsstäbe in beiden Richtungen und dem händischen Verknüpfen der Bewehrungsstäbe an der Verle¬ gestelle. Die Lagermatten haben den Nachteil, daß sie zugeschnitten werden müssen und daß ein entsprechender Materialverlust durch Verschnitt gegeben ist. Die Listenmatten besitzen den Nachteil, daß zum Abdecken aller möglichen Bewehrungsaufgaben eine Vielzahl von verschiedenen Typen in kleinen Stückzahlen vorgefertigt werden muß und keine Pro- duktion auf Vorrat möglich ist.It is known to reinforce sheet-like steel-concrete structures with the help of reinforcement bars to be laid individually, with the help of prefabricated reinforcement mats, so-called bearing mats, which have to be adapted accordingly and therefore cut to size, or with the help of prefabricated ones to the static ones reinforcement mats, so-called list mats, tailored to the spatial requirements. The disadvantage of the bar reinforcement is the large amount of work involved in laying the reinforcement bars in both directions and the manual linking of the reinforcement bars at the laying point. The disadvantage of the bearing mats is that they have to be cut to size and that there is a corresponding loss of material due to waste. The list mats have the disadvantage that in order to cover all possible reinforcement tasks, a large number of different types must be prefabricated in small quantities and production is not possible in stock.
Weiterhin ist bekannt, mehrere in einer Ebene parallel verlaufende Bewehrungsstäbe mit Hilfe von senkrecht zu den Be¬ wehrungsstäben verlaufenden und schwächer als diese ausgebilde¬ ten Haltestäben zu formstabilen, streifenförmigen Bewehrungse- lementen zusammenzuschweißen. Hiebei betragen die Abstände der Bewehrungsstäbe 15, 20 oder 30 cm, deren Durchmesser 8 bis 20 mm und die Anzahl der Bewehrungsstäbe in einem Bewehrungse¬ lement je nach Abstand vier, acht oder sechs, wobei innerhalb eines Elementes die Durchmesser der Bewehrungsstäbe verschieden sein können. Die Abstände der Haltestäbe betragen 1,2 m und der Abstand der Bewehrungsstabenden von den endseitigen Haltestäben beträgt mindestens 60 und maximal 120 cm. Die Längen der Beweh¬ rungselemente sind im Bereich von 2,4 bis 14 m wählbar. Nach¬ teilig ist bei diesen Bewehrungselementen die Tatsache, daß ei- ne Vielzahl von Bewehrungselementen mit unterschiedlichem Auf¬ bau vorhanden sein mußte, was eine Lagerhaltung praktisch unmöglich macht. Ein weiterer Nachteil liegt in den großen seitlichen Überstanden der Bewehrungsstabe, wodurch insbesondere bei kleineren Durchmessern ein Verbiegen der Be¬ wehrungsstabe beim Transport und bei der Handhabung nicht zu vermeiden ist. Die großen und konstanten Abstände der Halte¬ stabe sind ebenfalls nachteilig, da sie ein für die Manipulation und den Transport labiles Produkt ergeoen und an der Verlegestelle eine Aufteilung langer Elemente in formstabile Teilelemente verhindern.It is also known to weld a plurality of reinforcing bars running parallel in one plane with the aid of holding bars running perpendicular to the reinforcing bars and weaker than these designed to form dimensionally stable, strip-shaped reinforcing elements. The distances between the reinforcing bars are 15, 20 or 30 cm, their diameter is 8 to 20 mm and the number of reinforcing bars in a reinforcing element is four, eight or six, depending on the distance, it being possible for the diameter of the reinforcing bars to be different within one element. The distances between the support bars are 1.2 m and the distance between the reinforcement bar ends and the end support bars is at least 60 and a maximum of 120 cm. The lengths of the reinforcement elements can be selected in the range from 2.4 to 14 m. A disadvantage of these reinforcement elements is the fact that A large number of reinforcement elements with different structures had to be present, which makes storage practically impossible. A further disadvantage lies in the large overhangs of the reinforcing bar on the side, which means that, particularly with smaller diameters, bending of the reinforcing bar cannot be avoided during transport and handling. The large and constant spacings of the holding rod are also disadvantageous, since they result in a product which is unstable for manipulation and transport and prevent long elements from being divided into dimensionally stable sub-elements at the laying point.
Aus der AT-PS 346 046 ist eine Bewehrung für kreuzweise bewehrte Deckenplatten mit zumindest zwei für sich getrennten, unter sich korαbmationsfahigen Teilbewehrungsele enten bekannt, deren jedes eine Schar von in einer Richtung parallel verlau¬ fenden und biegesteif zusammengefaßten Stäben aufweist. Hiebei werden die Teilbewenrungselemente kreuzweise uberemanderge- legt, so daß sie eine Flachenbewehrung mit sich kreuzenden Be¬ wehrungsstaben belieoiger Abmessung und beliebigen Stahlquer- Schnittes bilden. Die Teilbewehrungselemente bestehen aus meh¬ reren gleich langen Bewehrungsstaben, die durch zwei Haltestabe biegesteif zusammengefaßt werden. Die Teilbewehrungselemente sind unter Zugrundelegung eines Rasters mit konstantem Modul aufgebaut, wobei die Abstände der Bewehrungsstabe αem Modul, die Lange des Teilbewehrungselementes einem Vielfachen des Mo¬ duls und die Lange αer Haltestabe sowie damit die Breite des Teilbewehrungselementes vorzugsweise einem Mehrfachen des Mo¬ duls entsprecnen. Der Abstand der Haltestabe von den Enden der Bewehrungsstabe muß zumindest die doppelte Haftlange des Beweh- rungsstabes vermehrt um den Modul betragen. Um die Elemente m Baukastenform zusammenfassen zu können, muß außerdem auch der Stahlquerschnitt der Bewehrungsstabe entsprechend der Langenab- messung des Elementes in bestimmter Weise abgestuft sein. Das Teilbewehrungselement hat den Nachteil, daß sein Aufbau in ei- nem vorgegebenen Rastermaß erfolgen muß und seine Herstellung daher sehr kompliziert und aufwendig ist. Außerdem ist eine große Typenvielfalt zur Losung der Bewehrungsaufgaben erforder¬ lich und eine rasche und flexible Anpassung an auf der Bau¬ stelle zu anαernde Verlegeplane nicht möglich. Aus der AT-PS 275 111 ist eine Bewehrungseinheit zum Be¬ wehren von Flächenstreifen bekannt, deren Breite 0,2 bis 0,7 m beträgt und die mindestens drei und höchstens vier Längsdrähte aufweist, welche durch mehrere, die Formbeständigkeit der Be- wehrungseinheit gewährleistende, quer verlaufende und schwächer ausgebildete Querdrähte verbunden sind. Diese Bewehrungse"nheit hat den Nachteil, daß die Anzahl der Längsdrähte beschräi. ist und daher nur relativ schmale Bewehrungsstreifen hersteilbar sind. Außerdem werden weder zur Anordnung der Querdrähte noch zu den Abmessungen der Bewehrungsstäbe nähere Angaben gemacht. Aufgabe der Erfindung ist es, einen universell einsetzba¬ ren, einfachen Betonstahlstreifen zu schaffen, der es ermög¬ licht, mit nur einer geringen Anzahl von serienmäßig herstell¬ baren Grundtypen von Betonstahlstreifen ein Lagerprogramm zu erstellen und auf einfache Weise sowie mit geringem Arbeits¬ aufwand die Bewehrung von flächenartigen Stahlbetonkonstruk¬ tionen durchzuführen, wobei die Nachteile der Stabbewehrung, der als Lager- und Listenmatten ausgeführten Bew-. rungsmatten sowie der bekannten streifenförmigen Bewehrungselemente vermieden werden sollen. Diese Aufgabe wird bei einem Betonstahlstreifen der einleitend angegebenen Art erfindungsgemäß durch die Kombination der Merkmale gelöst, daß der Betonstahlstreifen zur Bildung von Standard-Bewehrungs¬ elementen eines Lagerprogrammes eine Breite von mindestens 1000 und höchstens 1200 mm sowie eine Länge im Bereich von 4 bis 9 m hat und aus höchstens sieben in einem Abstand von 200 mm zueinander angeordneten Bewehrungsstäben mit gerippter Oberfläche und mit einem Durchmesser im Bereich von 6 bis 16 mm sowie aus mehreren, in einem Abstand von 400 bis 1200 mm zueinander angeordneten Positionsdrähten gebildet ist, wobei die den freien Enden der Bewehrungsstäbe benachbarten Positionsdrähte von den Bewehrungsstabenden einen Abstand von 200 bis 500 mm haben. Gemäß einer bevorzugten Ausführungsform der Erfindung bestehen die Bewehrungsstäbe aus warmgewalztem oder alternativ aus kaltverformtem Bewehrungsstahl.From AT-PS 346 046 a reinforcement for cross-reinforced ceiling slabs is known with at least two separate reinforcement elements which are capable of being corrugated, each of which has a group of bars which run in one direction and are combined in a rigid manner. In this case, the partial reinforcement elements are superimposed crosswise, so that they form a flat reinforcement with reinforcing bars of any dimension crossing each other and any steel cross-section. The partial reinforcement elements consist of several reinforcement bars of equal length, which are combined in a rigid manner by two holding bars. The partial reinforcement elements are constructed on the basis of a grid with a constant module, the spacings of the reinforcement bar as a module, the length of the partial reinforcement element corresponding to a multiple of the module and the length as a support bar and thus the width of the partial reinforcement element preferably corresponding to a multiple of the module. The distance between the holding bar and the ends of the reinforcing bar must be at least twice the adhesive length of the reinforcing bar around the module. In order to be able to summarize the elements in modular form, the steel cross-section of the reinforcing bar must also be graded in a certain way according to the length of the element. The partial reinforcement element has the disadvantage that its construction must take place in a predetermined grid dimension and its production is therefore very complicated and expensive. In addition, a large variety of types is required for solving the reinforcement tasks and a quick and flexible adaptation to the tarpaulin to be fixed on the construction site is not possible. From AT-PS 275 111 a reinforcement unit for reinforcing flat strips is known, the width of which is 0.2 to 0.7 m and which has at least three and at most four longitudinal wires, which by means of several ensure the dimensional stability of the reinforcement unit , transverse and weaker cross wires are connected. This reinforcement unit has the disadvantage that the number of longitudinal wires is limited and therefore only relatively narrow reinforcement strips can be produced. Furthermore, no details are given on the arrangement of the transverse wires or the dimensions of the reinforcement bars. The object of the invention is to provide a universal one usable, simple rebar strips, which make it possible to create a stock program with only a small number of standard types of rebar strips that can be produced in series and to carry out the reinforcement of flat reinforced concrete constructions in a simple manner and with little work , whereby the disadvantages of the bar reinforcement, the reinforcement mats designed as storage and list mats and the known strip-shaped reinforcement elements are to be avoided. This object is achieved according to the invention in a reinforcing steel strip of the type specified in the introduction by the combination of the features st that the reinforcing steel strip for the formation of standard reinforcement elements of a stock program has a width of at least 1000 and at most 1200 mm and a length in the range of 4 to 9 m and from a maximum of seven reinforcement bars arranged at a distance of 200 mm from one another with ribbed Surface and with a diameter in the range of 6 to 16 mm and from a plurality of positioning wires arranged at a distance of 400 to 1200 mm from one another, the positioning wires adjacent to the free ends of the reinforcing bars being at a distance of 200 to 500 mm from the reinforcing bar ends . According to a preferred embodiment of the invention, the reinforcing bars consist of hot-rolled or alternatively cold-formed reinforcing steel.
Vorzugsweise schließen die Positionsdrähte mit den Bewehrungsstäben bündig ab.The positioning wires are preferably flush with the reinforcing bars.
Die Erfindung gewährleistet, daß die Betonstahlstreifen mit geringstem Zuschneideaufwand annäherend verlustfrei an die Abmessungen der zu bewehrenden Stahlbetonbauteile angepaßt wer¬ den können. Die Betonstahlstreifen sind ausreichend steif und einfach manipulierbar. Auf Grund der Breite von 1000 bis 1200 mm benötigt man geringere Lagerflächen für den Beton- stahlstreifen. Infolge der angegebenen Überstände der Beweh¬ rungsstäbe ist ein Einschieben der Betonstahlstreifen an den Auflagern in Bewehrungen od.dgl. problemlos möglich und müssen die Positionsdrähte an den Betonstahlstreifenenden beim Verle¬ gen nicht aufgetrennt werden. Mit Hilfe des erfindungsgemäßen Betonstahlstreifens werden Standard-Bewehrungselemente eines Lagerprogrammes gebildet, wo¬ bei für einen Durchmesser der Bewehrungsstäbe jeweils nur ein Grundtyp von Betonstahlstreifen in verschiedenen Längen serien¬ mäßig erzeugt wird. In optimaler Weise lassen sich daher mit Hilfe der Betonstahlstreifen alle Bewehrungsaufgaben lösen, so daß die bisher erforderliche Vielzahl an streifenförmigen Be¬ wehrungselementen, Lager- oder Listenmatten durch nur wenige Grundtypen von erfindungsgemäßen Betonstahlstreifen ersetzt werden kann. Bei der Erstellung eines Bewehrungsplanes kann der erfindungsgemäße Betonstahlstreifen wie ein breiter Bewehrungs¬ stab behandelt werden.The invention ensures that the reinforcing steel strips with almost no cutting effort to the loss Dimensions of the reinforced concrete components to be reinforced can be adapted. The reinforcing steel strips are sufficiently stiff and easy to manipulate. Due to the width of 1000 to 1200 mm, smaller storage areas are required for the reinforcing steel strip. As a result of the specified projections of the reinforcement bars, the reinforcing steel strips can be pushed into the supports in reinforcements or the like. possible without any problems and the position wires at the ends of the reinforcing steel strip do not have to be separated when laying. With the help of the reinforcing steel strip according to the invention, standard reinforcement elements of a storage program are formed, whereby only one basic type of reinforcing steel strip in different lengths is produced in series for a diameter of the reinforcing bars. All reinforcement tasks can therefore be solved in an optimal manner with the aid of the reinforcing steel strips, so that the previously required large number of strip-shaped reinforcement elements, bearing or list mats can be replaced by only a few basic types of reinforcing steel strips according to the invention. When creating a reinforcement plan, the reinforcing steel strip according to the invention can be treated like a wide reinforcement bar.
Gegenüber der Herstellung herkömmlicher streifenförmiger Bewehrungselemente, Lager- oder Listenmatten kann der Beton¬ stahlstreifen besonders einfach und wirtschaftlich erzeugt werden, weil bereits bei der Herstellung der warmgewalzten Bewehrungsstäbe direkt im Anschluß an das Kühlbett des Walzwerkes die einzelnen Bewehrungsstäbe auf eine Vielfachlänge der Endlänge des Betonstahlstreifens geschnitten und zu Bündeln gleicher Länge zusammengefaßt werden. Im Herstellerwerk für die Betonstahlstreifen werden die Bewehrungsstäbe diesen Bündeln entnommen und auf die Standardlängen des entsprechenden Betonstahlstreifens geschnitten. Die bei herkömmlichen Lagermatten erforderliche zeitraubende und aufwendige Schneid¬ arbeit an der Verlegestelle oder bei den Verkaufslagern entfällt.Compared to the production of conventional strip-shaped reinforcement elements, bearing or list mats, the reinforcing steel strip can be produced particularly simply and economically, because during the production of the hot-rolled reinforcing bars directly after the cooling bed of the rolling mill, the individual reinforcing bars are cut to a multiple length of the final length of the reinforcing steel strip and combined into bundles of the same length. In the manufacturing plant for the reinforcing steel strips, the reinforcing bars are removed from these bundles and cut to the standard lengths of the corresponding reinforcing steel strips. The time-consuming and time-consuming cutting work required at conventional storage mats at the laying point or at the sales stores is eliminated.
Zur Herstellung der Betonstahlstreifen werden die Beweh¬ rungsstäbe mit Hilfe von handelsüblichen Gitterschweißmaschinen mit den Positionsdrähten verschweißt. Bei einer Breite des Be¬ tonstahlstreifens von 1,2 m können dabei die Stan- dard-Produktionsbreite dieser Gitterschweißmaschinen optimal ausgenutzt und in einer Schweißmaschine gleichzeitig zwei Bah¬ nen von Betonstahlstreifen besonders wirtschaftlich erzeugt werden. Die Breite von 1,2 m des Betonstahlstreifens hat weiterhin den Vorteil, daß die Standard-Ladefläche der Lastkraftwagen von 2,4 m beim Transport der Betonstahlstreifen optimal ausgenutzt werden kann.To produce the reinforcing steel strips, the reinforcement bars are welded to the positioning wires using commercially available grid welding machines. With a width of the concrete steel strip of 1.2 m, the standard The production range of these lattice welding machines is optimally utilized and two webs of reinforcing steel strips can be produced particularly economically in one welding machine. The width of 1.2 m of the reinforcing steel strip has the further advantage that the standard loading area of the trucks of 2.4 m can be optimally used when transporting the reinforcing steel strips.
Gegenüber Listenmatten hat der erfindungsgemäße Betonstahlstreifen den Vorteil, daß er abhängig von Gewicht und Länge von einer Arbeitskraft oder höchstens zwei Arbeitskräften manipuliert und auch hochkant transportiert werden kann. Ein weiterer Vorteil gegenüber Listenmatten liegt darin, daß in einfacher Weise bei einer kreuzweise zu bewehrenden Stahlbetonkonstruktion die Bewehrung in den beiden Richtungen unterschiedlich gewählt werden kann. Gegenüber den herkömmlichen Bewehrungsmatten, ob als Lager- oder Listen¬ matten, hat der erfindungsgemäße Betonstahlstreifen den Vor¬ teil, daß beim Verlegen keine Überdeckungsstöße und damit keine Stahlanhäufungen und kein Verlust an statischer Höhe durch Mehrlagigkeit im Stoßbereich entstehen.Compared to list mats, the reinforcing steel strip according to the invention has the advantage that, depending on the weight and length, it can be manipulated by one worker or at most two workers and can also be transported upright. Another advantage over list meshes is that the reinforcement can be selected differently in the two directions in a reinforced concrete construction to be reinforced crosswise. Compared to conventional reinforcement meshes, whether as storage or list meshes, the reinforcing steel strip according to the invention has the advantage that there are no overlaps and therefore no steel accumulations and no loss of static height due to multiple layers in the joint area.

Fig. 2 einen Schnitt desselben.Fig. 2 shows a section of the same.
Der in den Fig. 1 und 2 dargestellte Betonstahlstreifen 1 besteht aus sieben zueinander parallelen, mit einem gegenseiti- gen Abstand von 200 mm in einer Ebene angeordneten Bewehrungs¬ stäben 2, die durch mehrere querverlaufende Positionsdrähte 3, 3' miteinander verbunden sind. Der Betonstahlstreifen 1 hat ei¬ ne Breite von 1200 mm. Im Rahmen der Erfindung kann die Anzahl der Bewehrungsstäbe 2 auch sechs betragen, so daß auch Beton- stahlstreifen mit einer Breite von 1000 mm herstellbar sind.The reinforcing steel strip 1 shown in FIGS. 1 and 2 consists of seven reinforcing bars 2 which are parallel to one another and at a distance of 200 mm from one another and are connected to one another by a plurality of transverse positioning wires 3, 3 '. The reinforcing steel strip 1 has a width of 1200 mm. Within the scope of the invention, the number of reinforcing bars 2 can also be six, so that concrete steel strips with a width of 1000 mm can also be produced.
Die Durchmesser der Bewehrungsstäbe 2 liegen entsprechend den statischen Anforderungen an den Betonstahlstreifen 1 im Bereich von 6 bis 16 mm. Hiebei erfolgt die Durchmesser¬ abstufung der Bewehrungsstäbe 2 im Bereich von 6 bis 10 mm in Schritten von 1 mm und im Bereich von 10 bis 16 mm in Schritten von 2 mm. Die Oberfläche der Bewehrungsstäbe 2 ist mit Rippen versehen, um die Haftung der Bewehrungsstäbe 2 im Beton zu erhöhen. Die Bewehrungsstäbe 2 bestehen entweder aus warmge- walztem oder kaltverformtem, gezogenem oder gewalztem Be¬ wehrungsstahl mit mechanischen Festigkeitswerten entsprechend den statischen Anforderungen an den Betonstahlstreifen 1.The diameters of the reinforcement bars 2 are in the range from 6 to 16 mm in accordance with the static requirements for the reinforcing steel strip 1. The diameter of the reinforcing bars 2 is in the range from 6 to 10 mm in 1 mm increments and in the range of 10 to 16 mm in 2 mm increments. The surface of the reinforcing bars 2 is provided with ribs in order to increase the adhesion of the reinforcing bars 2 in the concrete. The reinforcing bars 2 consist either of hot-rolled or cold-formed, drawn or rolled reinforcing steel with mechanical strength values corresponding to the structural requirements for the reinforcing steel strip 1.
Der Betonstahlstreifen 1 hat eine Länge im Bereich von 4 bis 9 m, wobei die Längenabstufung im Bereich von 4 bis 7 m in Schritten von 500 mm und im Bereich von 7 bis 9 m in Schritten von 1000 mm erfolgt. Mit diesen Längenabstufungen ist es mög¬ lich, daß nur ein geringer Anteil an Betonstahlstreifen zugeschnitten werden muß und daß man sich nahezu verlustfrei an die Abmessungen der zu bewehrenden Stahlbetonbauteile anpassen kann.The reinforcing steel strip 1 has a length in the range from 4 to 9 m, the length gradation taking place in the range from 4 to 7 m in steps of 500 mm and in the range from 7 to 9 m in steps of 1000 mm. With these gradations in length, it is possible that only a small proportion of reinforcing steel strips has to be cut and that one can adapt to the dimensions of the reinforced concrete components to be reinforced almost without loss.
Die Abstände der Positionsdrähte 3, 3' zueinander liegen im Bereich von 400 bis 1200 mm und betragen vorzugsweise 500 oder 1000 mm. Die Anzahl der Positionsdrähte 3, 3' ergibt sich aus der Gesamtlänge des Betonstahlstreifens 1, wobei die beiden äußeren, den freien Enden der Bewehrungsstäbe 2 benachbarten Positionsdrähte 3' derart angeordnet sind, daß ein seitlicher Überstand 4 der Bewehrungsstäbe 2 entsteht, wobei die Länge des Uberstandes 4 entsprechend der Gesamtlänge des Betonstahlstrei¬ fens 200 bis 500 mm beträgt. Bei den bevorzugten Abständen der Positionsdrähte 3, 3' von 500 und 1000 mm betragen die Über¬ stände 4 der Bewehrungsstäbe 250 oder 500 mm. Die Überstände 4 werden deshalb relativ groß gewählt, damit ein Einschieben der Betonstahlstreifen an den Auflagern in Unterzüge, querverlau¬ fende Bewehrungen, Träger od.dgl. problemlos und ohne Auftren- nung von Positionsdrähten möglich ist.The spacing of the positioning wires 3, 3 'from one another is in the range from 400 to 1200 mm and is preferably 500 or 1000 mm. The number of position wires 3, 3 'results from the total length of the reinforcing steel strip 1, the two outer position wires 3' adjacent to the free ends of the reinforcement bars 2 'being arranged such that a lateral projection 4 of the reinforcement bars 2 is formed, the length of the Overhang 4 is 200 to 500 mm, corresponding to the total length of the reinforcing steel strip. With the preferred spacing of the positioning wires 3, 3 'of 500 and 1000 mm, the overhangs 4 of the reinforcing bars are 250 or 500 mm. The protrusions 4 are therefore chosen to be relatively large so that the reinforcing steel strips are pushed into the supports in beams, transverse reinforcements, beams or the like. is possible without any problems and without disconnecting the positioning wires.
Da die Positionsdrähte 3, 3' keine statischen Aufgaben zu erfüllen haben, sind die Durchmesser der Positionsdrähte 3, 3' kleiner als die Durchmesser der Bewehrungsstäbe 2 und liegen im Bereich von 4 bis 10 mm. Die Durchmesserabstufung erfolgt in Schritten von 1 mm. Die Positionsdrähte 3, 3' haben eine glatte Oberfläche und erfordern keine speziellen Materialeigenschaf¬ ten, so daß sie beispielsweise aus Walzdraht bestehen können. Die Positionsdrähte 3, 3' sind mit den Bewehrungsstäben 2 an den Kreuzungspunkten verschweißt, wobei die Positionsdrahte 3, 3' bundig mit den Bewehrungsstaben 2 abschließen.Since the positioning wires 3, 3 'have no static tasks to perform, the diameters of the positioning wires 3, 3' are smaller than the diameter of the reinforcing bars 2 and are in the range from 4 to 10 mm. The diameter is graded in steps of 1 mm. The positioning wires 3, 3 'have a smooth surface and do not require any special material properties, so that they can consist, for example, of wire rod. The positioning wires 3, 3 'are connected to the reinforcing bars 2 welded the crossing points, the positioning wires 3, 3 'flush with the reinforcing bars 2.
Die Abstände und die Durchmesser der Positionsdrahte 3, 3? müssen derart getroffen werden, daß der Betonstahlstreifen 1 eine für den Transport, die Handhabung und Verlegung ausrei¬ chende Steiflgkeit und Formstabilitat aufweist. Im Rahmen der Erfindung ist es auch möglich, Betonstahlstreifen herzustellen, die unterschiedliche Abstände der Positionsdrahte innerhalb ei¬ nes Betonstahlstreifens aufweisen. Die Ver eilung der Positi- onsdrahte im Betonstahlstreifen wird in Abhängigkeit vr Durch¬ messer der Bewehrungsstabe auf d±e Formstabilitat dt eton- stahlstreifens, die Teilbarkeit langer Betonstahlstrei-;n und die Beibehaltung der Steifigkeit und Formstabilitat der Teil- streifen optimiert. Bei Bewehrungsstabdurchmessern von 6 und 7 mm betragt der Abstand der Positionsdrahte vorzugsweise 500 mm, und bei Durch¬ messern im Bereich von 12 bis 16 mm vorzugsweise 1000 mm. Bei Durchmessern der Bewehrungsstabe von 8 und 10 mm wird vorzugs¬ weise im mittleren Bereich des Betonstahlstreifens ein Abstand der Positionsdrahte von 500 mm und in den Randbereichen des Be¬ tonstahlstreifens 1 ein Abstand von 1000 mm gewählt. Durch diese Abstufungen in 500 mm und/oder 1000 mm Schritten entsteht ein regelmäßiger Maßstab, der das Verlegen der Betonstahlstrei¬ fen und die Kontrolle dieser Verlegung erleichtert. Die Verlegung der erfmdungsgemaßen Betonstahlstreifen ge¬ schieht in folgender Weise: Die Betonstahlstreifen werden zu¬ nächst in einer Richtung nebenemanderliegend verlegt, wobei alle Bewehrungsstabe in einer Ebene und parallel zueinander an¬ geordnet sind. Anschließend erfolgt die Verlegung der Beton- stahlstreifen in der anderen, senkrecht verlaufenden Richtung, wobei auch hiebei die Bewehrungsstabe aller Betonstahlstreifen in einer Ebene liegen.The distances and the diameters of the positioning wires 3, 3 ? must be made in such a way that the reinforcing steel strip 1 has sufficient rigidity and dimensional stability for transport, handling and laying. Within the scope of the invention it is also possible to produce reinforcing steel strips which have different spacings of the position wires within a reinforcing steel strip. The Ver eilung the positive onsdrahte in the concrete steel strip is a function vr D urch¬ diameter of the reinforcing character of d ± e dimensional stability dt Eton steel strip, the divisibility long Betonstahlstrei-; s and the retention of rigidity and shape stability optimized strip of the participants. With reinforcement bar diameters of 6 and 7 mm, the spacing of the positioning wires is preferably 500 mm, and for diameters in the range from 12 to 16 mm, preferably 1000 mm. In the case of diameters of the reinforcement bars of 8 and 10 mm, a spacing of the positioning wires of 500 mm is preferably selected in the central region of the reinforcing steel strip and a spacing of 1000 mm in the edge regions of the reinforcing steel strip 1. These gradations in steps of 500 mm and / or 1000 mm result in a regular scale which facilitates the laying of the reinforcing steel strips and the control of this laying. The reinforcing steel strips according to the invention are laid in the following way: The reinforcing steel strips are first laid next to one another in one direction, with all reinforcing bars being arranged in one plane and parallel to one another. The reinforcing steel strips are then laid in the other, vertical direction, with the reinforcing bars of all the reinforcing steel strips lying in one plane.
