Description
Die Erfindung betrifft einen Betonstahlstreifen für flächenartige Stahlbetonkonstruktionen, bestehend aus mehreren zueinander parallelen, mit gegenseitigem Abstand in einer Ebene angeordneten Bewehrungsstäben und mehreren senkrecht zu den Bewehrungsstäben 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 several to each other parallel, with mutual spacing in one plane arranged reinforcing bars and several perpendicular to the reinforcing bars trending, weaker than this trained and with these welded positioning wires.
Es ist bekannt, die Bewehrung von flächenartigen Stahlbetonkonstruktionen mit Hilfe von einzeln zu verlegenden Bewehrungsstäben, mit Hilfe von vorgefertigten Bewehrungsmatten, sogenannten Lagermatten, die entsprechend angepaßt und daher zugeschnitten werden müssen, oder mit Hilfe von vorgefertigten, an die statischen und räumlichen Anforderungen maßgerecht angepaßten Bewehrungsmatten, sogenannten Listenmatten, auszuführen. Der Nachteil der Stabbewehrung besteht im großen Arbeitsaufwand beim Verlegen der Bewehrungsstäbe in beiden Richtungen und dem händischen Verknüpfen der Bewehrungsstäbe an der Verlegestelle. 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 Produktion auf Vorrat möglich ist.It is known to reinforce sheet-like reinforced concrete structures with the help of reinforcement bars to be laid individually, with the help of prefabricated reinforcement mats, so-called Storage mats that are adjusted accordingly and therefore need to be cut, or with the help of pre-made, tailored to the static and spatial requirements Reinforcement meshes, so-called list meshes. The disadvantage of the bar reinforcement is the large amount of work when laying the reinforcing bars in both directions and manually connecting the reinforcing bars at the installation point. The storage mats have the disadvantage that they must be tailored and that a corresponding Material loss due to waste is given. The list mats have the disadvantage that to cover all possible Reinforcement tasks a variety of different types in small quantities have to be prefabricated and no production possible on stock.
Weiterhin ist bekannt, mehrere in einer Ebene parallel verlaufende Bewehrungsstäbe mit Hilfe von senkrecht zu den Bewehrungsstäben verlaufenden und schwächer als diese ausgebildeten Haltestäben zu formstabilen, streifenförmigen Bewehrungselementen 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 Bewehrungselement 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 Bewehrungselemente sind im Bereich von 2,4 bis 14 m wählbar. Nachteilig ist bei diesen Bewehrungselementen die Tatsache, daß eine Vielzahl von Bewehrungselementen mit unterschiedlichem Aufbau vorhanden sein müßte, was eine Lagerhaltung praktisch unmöglich macht. Ein weiterer Nachteil liegt in den großen seitlichen Uberständen der Bewehrungsstäbe, wodurch insbesondere bei kleineren Durchmessern ein Verbiegen der Bewehrungsstäbe beim Transport und bei der Handhabung nicht zu vermeiden ist. Die großen und konstanten Abstände der Haltestäbe sind ebenfalls nachteilig, da sie ein für die Manipulation und den Transport labiles Produkt ergeben und an der Verlegestelle eine Aufteilung langer Elemente in formstabile Teilelemente verhindern.Furthermore, several are known to be parallel in one plane reinforcing bars running perpendicular to the reinforcing bars trending and weaker than this Retaining bars for dimensionally stable, strip-shaped reinforcement elements to weld together. The distances between them are Reinforcement bars 15, 20 or 30 cm, the diameter of 8 to 20 mm and the number of reinforcement bars in a reinforcement element depending on the distance four, eight or six, being within of an element the diameters of the reinforcing bars differ could be. The distances between the support rods are 1.2 m and Distance of the reinforcement bar ends from 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. Disadvantageous with these reinforcement elements is the fact that a Variety of reinforcement elements with different structures should be present, which makes storage practical makes impossible. Another disadvantage is the big one lateral protrusions of the reinforcing bars, whereby Bending of the reinforcement bars, especially with smaller diameters not during transportation and handling is to avoid. The large and constant distances between the support rods are also disadvantageous because they are one for the Manipulation and transportation result in unstable product the installation site is divided into long elements prevent dimensionally stable sub-elements.
Aus der AT-PS 346 046 ist eine Bewehrung für kreuzweise bewehrte Deckenplatten mit zumindest zwei für sich getrennten, unter sich kombinationsfähigen Teilbewehrungselementen bekannt, deren jedes eine Schar von in einer Richtung parallel verlaufenden und biegesteif zusammengefaßten Stäben aufweist. Hiebei werden die Teilbewehrungselemente kreuzweise übereinandergelegt, so daß sie eine Flächenbewehrung mit sich kreuzenden Bewehrungsstäben beliebiger Abmessung und beliebigen Stahlquerschnittes bilden. Die Teilbewehrungselemente bestehen aus mehreren gleich langen Bewehrungsstäben, die durch zwei Haltestäbe biegesteif zusammengefaßt werden. Die Teilbewehrungselemente sind unter Zugrundelegung eines Rasters mit konstantem Modul aufgebaut, wobei die Abstände der Bewehrungsstäbe dem Modul, die Länge des Teilbewehrungselementes einem Vielfachen des Moduls und die Länge der Haltestäbe sowie damit die Breite des Teilbewehrungselementes vorzugsweise einem Mehrfachen des Moduls entsprechen. Der Abstand der Haltestäbe von den Enden der Bewehrungsstäbe muß zumindest die doppelte Haftlänge des Bewehrungsstabes vermehrt um den Modul betragen. Um die Elemente in Baukastenform zusammenfassen zu können, muß außerdem auch der Stahlquerschnitt der Bewehrungsstäbe entsprechend der Längenabmessung des Elementes in bestimmter Weise abgestuft sein. Das Teilbewehrungselement hat den Nachteil, daß sein Aufbau in einem vorgegebenen Rastermaß erfolgen muß und seine Herstellung daher sehr kompliziert und aufwendig ist. Außerdem ist eine große Typenvielfalt zur Lösung der Bewehrungsaufgaben erforderlich und eine rasche und flexible Anpassung an auf der Baustelle zu ändernde Verlegepläne nicht möglich.

Diese Bewehrungseinheit hat den Nachteil, daß die Anzahl der Längsdrähte beschränkt ist und daher nur relativ schmale Bewehrungsstreifen herstellbar sind. Außerdem werden weder zur Anordnung der Querdrähte noch zu den Abmessungen der Bewehrungsstäbe nähere Angaben gemacht.AT-PS 275 111 is a reinforcement unit for reinforcement known from area strips, the width of 0.2 to 0.7 m is and the at least three and at most four longitudinal wires has, which by several, the dimensional stability of the reinforcement unit guaranteeing, transverse and weaker trained 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 are. In addition, neither to the arrangement of the cross wires nor details on the dimensions of the reinforcing bars.

Diese Aufgabe wird bei einem Betonstahlstreifen der einleitend angegebenen Art erfindungsgemäß durch die Kombination der Merkmale gelöst, daß der Betonstahlstreifen zur Bildung von Standard-Bewehrungselementen 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.The object of the invention is to provide a universally applicable to create a simple reinforcing steel strip that allows with only a small number of series-producible ones Basic types of reinforcing steel strips a stock program too create and easily and with little effort the reinforcement of sheet-like reinforced concrete structures the disadvantages of rebar reinforcement, of reinforcement meshes designed as storage and list meshes as well as the known strip-shaped reinforcement elements should be avoided. This task is with a Reinforcing steel strips of the type specified in the introduction solved according to the invention by the combination of the features that the reinforcing steel strip for the formation of standard reinforcement elements of a stock program a width of at least 1000 and at most 1200 mm and a length in the range of 4 to 9 m and has a maximum of seven at a distance of 200 mm reinforcing bars arranged with each other with ribbed Surface and with a diameter in the range of 6 to 16 mm as well as several, at a distance of 400 to 1200 mm mutually arranged position wires is formed, wherein which are adjacent to the free ends of the reinforcing bars Position wires a distance of from the rebar ends 200 to 500 mm. According to a preferred embodiment According to the invention, the reinforcement bars consist of hot-rolled or alternatively from cold-formed reinforcing steel.
Vorzugsweise schließen die Positionsdrähte mit den Bewehrungsstäben bündig ab.The position wires preferably close with the Reinforcement bars flush.
Die Erfindung gewährleistet, daß die Betonstahlstreifen mit geringstem Zuschneideaufwand annäherend verlustfrei an die Abmessungen der zu bewehrenden Stahlbetonbauteile angepaßt werden können. Die Betonstahlstreifen sind ausreichend steif und einfach manipulierbar. Auf Grund der Breite von 1000 bis 1200 mm benötigt man geringere Lagerflächen für den Betonstahlstreifen. Infolge der angegebenen Uberstände der Bewehrungsstäbe ist ein Einschieben der Betonstahlstreifen an den Auflagern in Bewehrungen od.dgl. problemlos möglich und müssen die Positionsdrähte an den Betonstahlstreifenenden beim Verlegen nicht aufgetrennt werden.The invention ensures that the reinforcing steel strips with minimal cutting effort almost lossless to the Dimensions of the reinforced concrete components to be reinforced can. The reinforcing steel strips are sufficiently stiff and easy to manipulate. Due to the width from 1000 to 1200 mm less storage space is required for the reinforcing steel strip. As a result of the specified projections of the reinforcing bars is inserting the reinforcing steel strips on the Support in reinforcements or the like. easily possible and must the positioning wires at the reinforcing steel strip ends when laying not be separated.
Mit Hilfe des erfindungsgemäßen Betonstahlstreifens werden Standard-Bewehrungselemente eines Lagerprogrammes gebildet, wobei für einen Durchmesser der Bewehrungsstäbe jeweils nur ein Grundtyp von Betonstahlstreifen in verschiedenen Längen serienmäßig erzeugt wird. In optimaler Weise lassen sich daher mit Hilfe der Betonstahlstreifen alle Bewehrungsaufgaben lösen, so daß die bisher erforderliche Vielzahl an streifenförmigen Bewehrungselementen, 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 Bewehrungsstab behandelt werden.With the help of the reinforcing steel strip according to the invention Standard reinforcement elements of a stock program are formed, whereby for a diameter of the reinforcing bars only one Basic type of reinforcing steel strips in various lengths as standard is produced. In an optimal way, therefore Solve all reinforcement tasks with the help of the reinforcing steel strips, see above that the previously required variety of strip-shaped reinforcement elements, Storage or list mats by just a few Basic types of reinforcing steel strips according to the invention replaced can be. When creating a reinforcement plan, the Reinforcing steel strips according to the invention like a wide reinforcement bar be treated.
Gegenüber der Herstellung herkömmlicher streifenförmiger Bewehrungselemente, Lager- oder Listenmatten kann der Betonstahlstreifen 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 Schneidarbeit an der Verlegestelle oder bei den Verkaufs lagern entfällt.Compared to the production of conventional stripe-shaped The reinforcing steel strip can be used for reinforcement elements, bearing or list mats produced particularly easily and economically be because already during the production of the hot-rolled Reinforcing bars directly after the cooling bed of the Rolling mill the individual reinforcement bars to a multiple length cut the end length of the reinforcing steel strip and bundle them same length can be summarized. In the manufacturing plant for the Reinforcing steel strips become the reinforcement bars of these bundles removed and cut to the standard lengths of the corresponding Reinforcing steel strips cut. The conventional one Storage mats require time-consuming and complex cutting work store at the laying point or at the sales point not applicable.
Zur Herstellung der Betonstahlstreifen werden die Bewehrungsstäbe mit Hilfe von handelsüblichen Gitterschweißmaschinen mit den Positionsdrähten verschweißt. Bei einer Breite des Betonstahlstreifens von 1,2 m können dabei die Standard-Produktionsbreite dieser Gitterschweißmaschinen optimal ausgenutzt und in einer Schweißmaschine gleichzeitig zwei Bahnen von Betonstahlstreifen besonders wirtschaftlich erzeugt werden.The reinforcement bars are used to manufacture the reinforcing steel strips with the help of standard mesh welding machines welded to the positioning wires. With a width of the reinforcing steel strip the standard production width of 1.2 m of these mesh welding machines optimally exploited and two lanes simultaneously in one welding machine of reinforcing steel strips produced particularly economically become.
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.The width of 1.2 m of the reinforcing steel strip continues the advantage that the standard truck bed of 2.4 m optimally used when transporting the reinforcing steel strips can be.
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 Listenmatten, hat der erfindungsgemäße Betonstahlstreifen den Vorteil, 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 invention has Reinforcing steel strips the advantage that it depends on weight and Length of one worker or at most two workers manipulated and can also be transported upright. A Another advantage over list mats is that in simple way with a cross to be reinforced Reinforced concrete construction reinforcement in both directions can be chosen differently. Compared to the conventional reinforcement meshes, whether as storage or list meshes, the reinforcing steel strip according to the invention has the advantage that when laying there are no overlaps and therefore none Steel accumulations and no loss of static height Multiple layers in the joint area arise.

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 möglich, 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 of 4 to 9 m, the length gradation in the range of 4 to 7 m in Steps of 500 mm and in the range of 7 to 9 m in steps of 1000 mm. With these length gradations it is possible that only a small proportion of reinforcing steel strips must be tailored and that you look at almost lossless adjust the dimensions of the reinforced concrete components to be reinforced can.
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
Überstandes 4 entsprechend der Gesamtlänge des Betonstahlstreifens
200 bis 500 mm beträgt. Bei den bevorzugten Abständen der
Positionsdrähte 3, 3' von 500 und 1000 mm betragen die Überstände
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, querverlaufende
Bewehrungen, Träger od.dgl. problemlos und ohne Auftrennung
von Positionsdrähten möglich ist.The spacing of the
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 Materialeigenschaften,
so daß sie beispielsweise aus Walzdraht bestehen können.
Die Positionsdrähte 3, 3' sind mit den Bewehrungsstäben 2 an
den Kreuzungspunkten verschweißt, wobei die Positionsdrähte 3,
3' bündig mit den Bewehrungsstäben 2 abschließen.Since the
Die Abstände und die Durchmesser der Positionsdrähte 3, 3'
müssen derart getroffen werden, daß der Betonstahlstreifen 1
eine für den Transport, die Handhabung und Verlegung ausreichende
Steifigkeit und Formstabilität aufweist. Im Rahmen der
Erfindung ist es auch möglich, Betonstahlstreifen herzustellen,
die unterschiedliche Abstände der Positionsdrähte innerhalb eines
Betonstahlstreifens aufweisen. Die Verteilung der Positionsdrähte
im Betonstahlstreifen wird in Abhängigkeit vom Durchmesser
der Bewehrungsstäbe auf die Formstabilität des Betonstahlstreifens,
die Teilbarkeit langer Betonstahlstreifen und
die Beibehaltung der Steifigkeit und Formstabilität der Teilstreifen
optimiert.The distances and the diameters of the
Bei Bewehrungsstabdurchmessern von 6 und 7 mm beträgt der Abstand der Positionsdrähte vorzugsweise 500 mm, und bei Durchmessern im Bereich von 12 bis 16 mm vorzugsweise 1000 mm. Bei Durchmessern der Bewehrungsstäbe von 8 und 10 mm wird vorzugsweise im mittleren Bereich des Betonstahlstreifens ein Abstand der Positionsdrähte von 500 mm und in den Randbereichen des Betonstahlstreifens 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 Betonstahlstreifen und die Kontrolle dieser Verlegung erleichtert.For reinforcement bar diameters of 6 and 7 mm the is Distance of the positioning wires is preferably 500 mm, and for diameters in the range from 12 to 16 mm, preferably 1000 mm. At Diameters of the reinforcement bars of 8 and 10 mm are preferred a distance in the middle area of the reinforcing steel strip of the positioning wires of 500 mm and in the edge areas of the reinforcing steel strip 1 selected a distance of 1000 mm. By these gradations arise in 500 mm and / or 1000 mm steps a regular yardstick of laying the rebar strips and makes it easier to control this relocation.
Die Verlegung der erfindungsgemäßen Betonstahlstreifen geschieht in folgender Weise: Die Betonstahlstreifen werden zunächst in einer Richtung nebeneinanderliegend verlegt, wobei alle Bewehrungsstäbe in einer Ebene und parallel zueinander angeordnet sind. Anschließend erfolgt die Verlegung der Betonstahlstreifen in der anderen, senkrecht verlaufenden Richtung, wobei auch hiebei die Bewehrungsstäbe aller Betonstahlstreifen in einer Ebene liegen.The reinforcing steel strips according to the invention are laid in the following way: The reinforcing steel strips are first laid next to each other in one direction, whereby all reinforcement bars are arranged in one plane and parallel to each other are. Then the reinforcing steel strips are laid in the other, perpendicular direction, with the reinforcement bars of all reinforcing steel strips lie in one plane.
