Abstract

This reinforcement for reinforced concrete constructions, in particular flat-type supporting structures, possesses reinforcing elements (4) in the form of a series of stirrups (5), which are interconnected by means of rods (9) forming a longitudinal reinforcement. To reduce the number of parts to be handled individually which are required in the formation of such a reinforcement and for the easy and rapid assembly thereof, the free legs (7) of the stirrups (5) possess bent-up portions (8) which receive or embrace the longitudinal rods (9), as a result of which the elements (4) can be stacked. In this arrangement, the reinforcing elements (4) are arranged either individually next to one another or, in pairs, diametrically opposed inside one another and offset relative to one another, rod bundle elements, individual rods or mats being provided as a transverse reinforcement transversely to the longitudinal rods (9) of the stirrup elements (4) on the outsides thereof. <IMAGE>

Description

Zur Herstellung einer Bewehrung für Stahlbetonkonstruktionen, insbesondere für die Herstellung von beliebigen Wandbewehrungen, z.B. hohlkastenförmigen U-Bahnaschnitten, mußte man bisher bei einer Wand so vorgehen (zum leichteren Verständnis wird auf die Fig. 1 und 2 Bezug genommen, in denen eine Wandbewehrung in Seitenansicht und im Schnitt nach der Linie II-II der Fig. 1 dargestellt ist):For the production of reinforcement for reinforced concrete structures, in particular for the production of any wall reinforcement, e.g. previously hollow box-shaped subway sections had to be done with a wall (for easier understanding reference is made to FIGS. 1 and 2, in which a wall reinforcement is shown in side view and in section along the line II-II of FIG. 1) :

Zunächst wurden an einer (nicht dargestellten) Schalungswand (ebenfalls nicht dargestellte) vertikal angeordnete Montagestäbe festgelegt und an diesen die horizontalen Stäbe 1 und an letzteren wiederum, und zwar quer zu ihnen, die vertikalen Stäbe 2 befestigt, wodurch man ein Gitterwerk an der einen Schalungswand erhält. Sodann müssen (nicht dargestellte) Füssel als Abstandhalter angefügt werden, und mit deren Hilfe wird ein zweites Gitterwerk aus den vertikalen Stäben 2 und den horiontalen Stäben 1 hergestellt. Schließlich werden als die äußeren Gitterwerke verbindende Glieder S-Haken 3 in horizontalen und vertikalen Reihen eingefädelt, wobei diese mit ihren Haken mindestens die vertikalen Stäbe 2 umfassen müssen, um mit einer Stückzahl von 4/m² die Knicksicherung zu bilden; der Abstand Z der S-Haken beträgt demnach etwa 50 cm in horizontaler und vertikaler Richtung. Schließlich wird vor dem Betonieren die andere Schalungswand aufgestellt. Es sind also bei diesem bekannten Herstellungsvorgang nicht weniger als neun Bewehrungsteile einzeln handzuhaben, was einen hohen Zeitaufwand und umständliche Manipulationen umfaßt.First, vertically arranged mounting bars were fixed to a (not shown) formwork wall (also not shown) and to these the horizontal bars 1 and to the latter, in turn, perpendicular to them, the vertical bars 2 were fixed, thereby creating a latticework on one formwork wall receives. Then (not shown) feet must be added as spacers, and with the help of which a second latticework is produced from the vertical bars 2 and the horizontal bars 1. Finally, as links connecting the outer lattice works, S-hooks 3 are threaded in horizontal and vertical rows, these hooks having to enclose at least the vertical bars 2 in order to form the kink protection with a quantity of 4 / m²; the distance Z of the S-hooks is therefore approximately 50 cm in the horizontal and vertical directions. Finally, the other formwork wall is set up before concreting. In this known manufacturing process, therefore, no fewer than nine reinforcement parts can be handled individually, which involves a great deal of time and laborious manipulations.

Aus der DE-C-479 871 ist eine doppelte Metallbewehrung für Betonbauwerke aus vorbereiteten Gittergeflechten bekannt, wobei die Querstäbe der unteren Bewehrung gleichen Abstand voneinander haben und die der oberen Bewehrung in gruppengleichen Abständen zusammengefügt sind, zwischen denen größere Lücken von etwa dem doppelten bis dreifachen Abstand angeordnet sind. Beim Herstellen der endgültigen Be wehrung werden die Längsstäbe beider Lagen übereinander angeordnet und die Längsstäbe der oberen Bewehrung an den Stellen der großen Lücken zwischen Querstäben etwa in der Mitte zwischen den beiden nächstliegenden Verbindungsstellen durchschnitten. Die freien Enden der durchschnittenen Längsstäbe werden dann rechtwinkelig abgebogen und mit den unter ihnen liegenden Längsstäben der unteren Bewehrung im gewünschten Abstand verbunden. Damit müssen wichtige Arbeiten, wie das Herstellen und Ablängen der seitlichen Schenkel der U-Bügel unmittelbar an Ort und Stelle der herzustellenden Bewehrung vorgenommen werden, was komplizierte und zeitaufwendige Tätigkeiten von entsprechenden Fachleuten erfordert.From DE-C-479 871 a double metal reinforcement for concrete structures made of prepared meshes is known, the cross bars of the lower reinforcement being equidistant from one another and the upper reinforcement being joined at equal intervals, between which larger gaps of approximately double to triple Distance are arranged. When making the final Be reinforcement, the longitudinal bars of the two layers are arranged one above the other and the longitudinal bars of the upper reinforcement are cut at the locations of the large gaps between cross bars approximately in the middle between the two closest connecting points. The free ends of the cut longitudinal bars are then bent at right angles and connected to the longitudinal bars of the lower reinforcement below them at the desired distance. This means that important work, such as the production and cutting to length of the side legs of the U-bracket, has to be carried out directly on the spot of the reinforcement to be produced, which requires complicated and time-consuming activities by the corresponding experts.

Eine Bewehrung für Stahlbetonkonstruktionen, insbesondere flächenartige Tragwerke, mit vorgefertigten, einzelnen Bewehrungselementen in Form einer Reihe von U-Bügeln, die durch eine Längsbewehrung bildende Stäbe miteinander verbunden sind, ist aus der DE-OS 1 609 855 bekannt. Bei einer solchen Bewehrung sind die Tragstäbe gegen Ausknicken nicht gesichert, ihre Abstände voneinander sind unterschiedlich und sie lassen sich nicht in einer Ebene anordnen; außerdem ist eine lückenlose Anordnung der Tragbewehrung nicht möglich.Reinforcement for reinforced concrete structures, in particular sheet-like structures, with prefabricated, individual reinforcement elements in the form of a series of U-brackets which are connected to one another by bars forming longitudinal reinforcement, is known from DE-OS 1 609 855. With such a reinforcement, the supporting bars are not secured against buckling, their distances from one another are different and they cannot be arranged in one plane; in addition, a seamless arrangement of the supporting reinforcement is not possible.

Die Erfindung stellt sich die Aufgabe, eine Bewehrung zu schaffen, die, unter Vermeidung der vorgenannten Nachteile, aus weniger sowie leicht und rasch einzubauenden Bewehrungsteilen besteht, wobei ferner ihre Elemente maschinell herstellbar und stapelbar sein sollen. Außerdem sollen nach dem Einbau die Tragstäbe gleich beabstandet sein, in einer Ebene liegen und durch S-Hakenfunktion aufweisende Glieder umfaßt sein.The invention has for its object to provide a reinforcement, which, while avoiding the aforementioned disadvantages, consists of fewer and easier and quick to install reinforcement parts, wherein their elements should also be machine-made and stackable. In addition, after installation, the support rods should be equally spaced, lie in one plane and be encompassed by links having an S-hook function.

Gelöst wird dies durch eine Bewehrung für Stahlbetonkonstruktionen, insbesondere flächenartige Tragwerke, mit vorgefertigten, einzelnen Bewehrungselementen in Form einer Reihe von durch eine Längsbewehrung bildende Stäbe miteinanderverbundenen U-Bügeln, deren freie Schenkel, Längsstäbe aufnehmende bzw. umfassende Umbiegungen aufweisen, wobei die Bewehrungselemente in der zusammenge setzten Bewehrung paarweise gegengleich ineinander sowie unter Versetzung zueinander angeordnet sind, und quer zu den Längsstäben der Bewehrungselemente an deren Außenseiten als Querbewehrung dienende Stabscharelemente, Einzelstäbe oder Matten vorgesehen sind.This is solved by a reinforcement for reinforced concrete structures, in particular sheet-like structures, with prefabricated, individual reinforcement elements in the form of a series of U-brackets connected to one another by bars forming a longitudinal reinforcement, the free legs of which have longitudinal bends that accommodate or encompass longitudinal bars, the reinforcement elements in the merged are placed reinforcement in pairs opposite to each other and offset from each other, and transverse to the longitudinal bars of the reinforcement elements on the outer sides serving as transverse reinforcement bar coulter elements, single bars or mats are provided.

Durch eine solche Anordnung von Bewehrungselementen geben deren U-Bügel-Schenkel die benötigte Knicksicherung für die in ihren Umbiegungen liegenden Längsstäbe, und die Querbewehrung, z.B. Stabscharelemente, läßt sich dann an der Außenseite der U-Bügelelemente leicht und rasch anordnen. Die Querbewehrung kann dabei auch aus Einzelstäben oder Baustahlgewebematten bestehen. Die einzelnen Bewehrungselemente selbst sind damit leicht maschinell vorfertigbar und weisen auch für Transport und Lagerung ausreichende Handhabbarkeit und Stabilität auf. Bei der Herstellung der Bewehrung selbst müssen nur noch einfache Verbindungen der einzelnen Bewehrungselemente untereinander bzw. mit der Querbewehrung vorgenommen werden.Through such an arrangement of reinforcement elements, their U-bracket legs provide the required buckling protection for the longitudinal bars lying in their bends, and the transverse reinforcement, e.g. Bar coulter elements can then be easily and quickly arranged on the outside of the U-bracket elements. The cross reinforcement can also consist of single bars or steel mesh. The individual reinforcement elements themselves can thus be easily prefabricated by machine and also have sufficient handling and stability for transport and storage. When producing the reinforcement itself, only simple connections of the individual reinforcement elements to one another or to the transverse reinforcement have to be made.

Wie aus den Fig. 3 und 4 hervorgeht, besteht das Bewehrungselement 4 aus übereinander im Abstand Z, z.B. 50 cm, angeordneten U-Bügeln 5, die einen geraden Mittelteil 6, um 90° gegen den Mittelteil 6 abgebogene gerade Schenkel 7 und an deren freien Enden nach außen gerichtete Umbiegungen 8 über einen Winkel von etwa 180° aufweisen. Die U-Bügel 5 sind mit quer zu ihnen angeordneten, vertikalen Längsstäben 9 verbunden, z.B. durch Schweißung. Die Anordnung ist dabei so getroffen, daß nur ein Paar Stäbe 9 von den Umbiegungen 8 umfaßt wird.3 and 4, the reinforcement element 4 consists of one another at a distance Z, e.g. 50 cm, arranged U-brackets 5, which have a straight central part 6, bent straight legs 7 by 90 ° against the central part 6 and at their free ends outward bends 8 over an angle of approximately 180 °. The U-brackets 5 are connected to vertical longitudinal bars 9 arranged transversely to them, e.g. by welding. The arrangement is such that only a pair of rods 9 is covered by the bends 8.

Zur Herstellung eines Teiles der erfindungsgemäßen Bewehrung wird zunächst ein Paar von Bewehrungselementen 4 gegengleich und versetzt zueinander angeordnet (Fig.5), d.h. in das Element 4' wird ein (strichliert dargestelltes) Element 4" so eingeschoben, daß der Längsstab 9 des Elementes 4" in der Mitte des Mittelteiles 6 des Elemen tes 4' liegt. Dann liegen die in Fig. 5 linken Schenkel 7 des Elementes 4" etwa in der Symmetrieebene des Elementes 4' und zwangsläufig liegen umgekehrt die rechten Schenkel des Elementes 4' etwa in der Symmetrieebene des Elementes 4". Das Einschieben erfolgt solange, bis der Stab 9 in den Umbiegungen 8 der linken Schenkel 7 des Elementes 4" an die Mittelteile 6 der Elemente 4' anschlägt, und umgekehrt der Stab 9 in den Umbiegungen 8 der rechten Schenkel 7 der Elemente 4' an dem Mittelteil 6 der Elemente 4" anliegt. In dieser Weise liegen dann die Mittelteile 6 der Elemente 4', 4" in zwei zueinander parallelen Ebenen, ebenso wie die Stäbe 9 der Elemente 4', 4" in dazu benachbarten, parallelen Ebenen, u.zw. unter gleichen Abständen zueinander, liegen.To produce a part of the reinforcement according to the invention, a pair of reinforcement elements 4 is first arranged opposite and offset from one another (FIG. 5), ie an element 4 ″ (shown in broken lines) is inserted into the element 4 ′ in such a way that the longitudinal bar 9 of the element 4 "in the middle of the middle section 6 of the Elemen tes 4 'lies. Then the left leg 7 in FIG. 5 of the element 4 ″ lies approximately in the plane of symmetry of the element 4 ′, and the right leg is inevitably the other way round Leg of the element 4 'approximately in the plane of symmetry of the element 4 ". The insertion is carried out until the rod 9 in the bends 8 of the left leg 7 of the element 4" strikes the central parts 6 of the elements 4', and vice versa the rod 9 in the bends 8 of the right leg 7 of the elements 4 'against the middle part 6 of the elements 4 ". In this way, the middle parts 6 of the elements 4', 4" lie in two mutually parallel planes, just like the rods 9 of the elements 4 ', 4 "lie in adjacent, parallel planes, e.g. at equal distances from one another.

Die Fig. 6 bis 9 veranschaulichen, wie unter Verwendung eines Elementes nach den Fig. 3 und 4, das in Fig. 6 mit E1 bezeichnet und zusätzlich ein weiteres Paar Stäbe 9 an der Verbindungsstelle des Mittelteiles 6 mit den Schenkeln 7 aufweist, über einem Raster ein Baukastensystem gebildet werden kann. Bei dem Element E1 weist dabei, unter Zugrundelegung einer Rastereinheit X, der Abstand der beiden Stäbe 9 am Mittelteil 6 die Größe 2 X auf, wobei der Abstand vom Eckstab 9 am Mittelteil 6 zum Stab 9 in der anschließenden Umbiegung 8 den Abstand X 1 in der horizontalen Projektion und den Abstand Y in der vertikalen Projektion aufweist.6 to 9 illustrate how using an element according to FIGS. 3 and 4, which is labeled E1 in FIG. 6 and additionally has a further pair of rods 9 at the junction of the central part 6 with the legs 7, above one Grid a modular system can be formed. In the case of the element E1, based on a grid unit X, the distance between the two bars 9 on the central part 6 has the size 2 X, the distance from the corner bar 9 on the central part 6 to the bar 9 in the subsequent bend 8 being the distance X 1 in of the horizontal projection and the distance Y in the vertical projection.

Erhöht man die Länge des Mittelteiles 6 um X und ordnet man in seinem Drittelpunkt einen weiteren Stab 9a zwischen den Endstäben 9 an, kommt man zum Bügelelement E2 nach Fig. 7; mit zwei weiteren Stäben 9a und 9b, je in der Hälfte und im Viertelpunkt des Mittelteiles 6, zum Element E3 nach Fig. 8 und schließlich mit drei weiteren Stäben 9a, 9b und 9c zum Element E4 nach Fig. 9. Die Abstände der Stäbe 9 am Mittelteil 6 betragen dann 3X in Fig. 7, 4X in Fig. 8 und 5X in Fig. 9. In dieser Weise kann der Bauksten beliebig erweitert werden.If the length of the middle part 6 is increased by X and if a third rod 9a is arranged between the end rods 9 in its third point, the bracket element E2 according to FIG. 7 is obtained; with two further rods 9a and 9b, each in the half and in the quarter point of the middle part 6, to the element E3 according to FIG. 8 and finally with three further rods 9a, 9b and 9c to the element E4 according to FIG. 9. The spacings of the rods 9 on the central part 6 then amount to 3X in FIG. 7, 4X in FIG. 8 and 5X in FIG. 9. In this way, the modular system can be expanded as desired.

Wesentlich bei dieser Ausbildung der Bewehrungselemente E1 bis E4 als Teile eines Baukastensystems ist, daß jeweils bei den dargestellten Beispielen, der vom Eckstab 9 am linken Ende des Mittelteiles 6 nach rechts um die Rastereinheit X entfernt liegende Platz frei bleibt, dort also kein Zusatzstab angeordnet wird; mit anderen Worten, der Abstand von jenem Eckstab 9 zum benachbarten Stab 9a ist jeweils 2 X, wie den Fig.7 bis 9 zu entnehmen ist.It is essential in this embodiment of the reinforcement elements E1 to E4 as parts of a modular system that in the examples shown, that of the corner bar 9 at the left end of the middle part 6 to the right space around the grid unit X remains free, so no additional rod is arranged there; in other words, the distance from that corner bar 9 to the adjacent bar 9a is 2 X each, as can be seen in FIGS. 7 to 9.

Wünscht man gewisse, sich daraus ergebende, noch zu erläuternde Vorteile nicht zu beanspruchen, dann kann man auch eine Anordnung nach Fig. 10 treffen. In dieser Fig. 10 ist ein Element E5 dargestellt, bei dem am Mittelteil 6, den Eckstäben 9 benachbart, je zwei Stäbe 9d und 9e, jeweils im Abstand X zueinander, angeordnet sind, wogegen der Platz in der Mitte des Mittelteiles 6 unbesetzt bleibt.If one wishes not to claim certain resulting advantages which are yet to be explained, an arrangement according to FIG. 10 can also be made. In this FIG. 10, an element E5 is shown, in which two bars 9d and 9e, each at a distance X from one another, are arranged on the middle part 6, adjacent to the corner bars 9, whereas the space in the middle of the middle part 6 remains unoccupied.

Wenn man, wie in Fig. 5 gezeigt, die Elemente El bis E4 paarweise ineinandergeschoben anordnet, erhält man dann immer Stäbe 9, 9a, 9b usf., die an jedem Kreuzungspunkt des Rasters liegen (vgl. Fig. 2l, wo dies für ein gegenüber dem Element E3 nach Fig. 8 - in diesem Zusammenhang unwesentlich - abgeändertes Element E3.1 dargestellt ist: es liegen hier, wie bei Fig. 5, alle Stäbe 9 sowie die Zusatzstäbe 9a, 9b in zwei parallelen Ebenen, unter jeweils gleichen Abständen zueinander).If, as shown in Fig. 5, the elements E1 to E4 are pushed into each other in pairs, then you always get rods 9, 9a, 9b etc., which are located at each crossing point of the grid (see Fig. 2l, where this is for a Compared to element E3 according to FIG. 8, element E3.1, which is insignificant in this connection, is shown: here, as in FIG. 5, all rods 9 and additional rods 9a, 9b lie in two parallel planes, each with the same spacing to each other).

Damit wird erkenntlich, daß man sich durch Verändern der Zahl von Zusatzstäben 9a, 9b, 9c pro Element E1 bis E4 weiten Bereichen der notwendigen geforderten Vertikalbewehrung anzupassen vermag.This shows that by changing the number of additional bars 9a, 9b, 9c per element E1 to E4 it is possible to adapt to wide ranges of the required vertical reinforcement.

Verfährt man bei dem Element E5 nach Fig. 10 genau so, wie dies in strichlierten Linien dargestellt ist, erhält man Stellen F, an welchen Stäbe fehlen, obwohl die Stellen F Kreuzungspunkte des Rasters sind, u.zw. an den unterhalb der (in Fig. 10) linken Stäbe 9d und 9e liegenden Kreuzungspunkten, was in manchen Anwendungsfällen nicht zulässig sein mag.If the element E5 according to FIG. 10 is operated exactly as shown in dashed lines, one obtains points F at which bars are missing, although the points F are crossing points of the grid, etc. at the intersection points below the left rods (in FIG. 10) 9d and 9e, which may not be permissible in some applications.

Die Fig. 11 bis 14 veranschaulichen, ähnlich Fig. 3, die den Elementen E1 bis E4 nach den Fig. 6 bis 9 zugeordneten Seitenansichten, wobei die Bügel 5 wiederum den Abstand Z, vorzugsweise 50 cm, haben und Endteile der Stä be 9 mit den Längen Z1 und Z2 vorgesehen sind.11 to 14 illustrate, similar to FIG. 3, the side views assigned to the elements E1 to E4 according to FIGS. 6 to 9, the brackets 5 again having the distance Z, preferably 50 cm, and end parts of the bars be 9 with lengths Z1 and Z2 are provided.

Eine Abänderung gegenüber den Elementen E2 bis E4 nach Fig. 7 bis 9 und 12 bis 14 besteht für die Elemente E2.1 bis E4.1 nach den Fig. 16 bis 18 darin, daß nur jeder zweite der Bügel 5 mit voller Länge (also zwei Schenkel 7 am Mittelteil 6 gemäß Fig. 4) ausgebildet ist; der dazwischenliegende Bügel 5' ist, wie in Fig. 15 gezeigt, nur als Halbbügel ausgebildet, bestehend aus einem Schenkel 7' mit der Umbiegung 8 für den Stab 9 einenends und einem kurzen Geradstück 6', das sozusagen einen verkürzten Mittelteil bildet. In dieser Konzeption entspricht der Halbbügel 5' in etwa dem S-Haken nach den Fig. 1 und 2. Natürlich könnte auch jeder dritte, vierte usw. Bügel 5 mit voller Länge und die dazwischenliegenden als Halbbügel 5' ausgebildet sein.A change compared to the elements E2 to E4 according to FIGS. 7 to 9 and 12 to 14 for the elements E2.1 to E4.1 according to FIGS. 16 to 18 is that only every second one of the brackets 5 is full-length (i.e. two legs 7 is formed on the central part 6 according to FIG. 4); The intermediate bracket 5 ', as shown in Fig. 15, is formed only as a half bracket, consisting of a leg 7' with the bend 8 for the rod 9 at one end and a short straight piece 6 ', which forms a shortened middle part, so to speak. In this conception, the half-bar 5 'corresponds approximately to the S-hook according to FIGS. 1 and 2. Of course, every third, fourth, etc. bar 5 could also be designed with the full length and the intermediate bars 5'.

Diese Elemente E2-1 bis E4.1 lassen sich nicht nur genau so wie die Bewehrungselemente E2 bis E4 mit dem Element E1 kombinieren, sie weisen außerdem durch die Halbbügel 5' einen geringeren Stahlbedarf bei ihrer Herstellung auf, und dies unter Erfüllung der Forderung nach z.B. 4 Bügeln/m² als Knicksicherung.These elements E2-1 to E4.1 can not only be combined with the element E1 in exactly the same way as the reinforcement elements E2 to E4, they also have a lower steel requirement in their manufacture due to the half-brackets 5 ', and this in compliance with the requirement e.g. 4 brackets / m² as kink protection.

Das andere, an sich bekannte, mit den Bewehrungselementen nach den Fig.3 bis 18 zu kombinierende Bewehrungsteil 10 besteht gemäß Fig. 19 z.b. aus einer Schar von horizontalen Stäben 11, die durch voneinander im Abstand liegende Querstäbe 12 gehalten, bevorzugt mit diesen verschweißt sind.The other, known per se, to be combined with the reinforcement elements according to FIGS. 3 to 18 consists according to FIG. 19 e.g. from a group of horizontal bars 11, which are held by transverse bars 12 spaced apart from one another, preferably welded to them.

Die Herstellung einer erfindungsgemäßen Bewehrung aus den Elementen 4 bzw. E1 und 10 ist in der bereits erläuterten Fig. 5 und der Fig. 20 erkenntlich.The manufacture of a reinforcement according to the invention from elements 4 or E1 and 10 can be seen in FIG. 5 and FIG. 20 already explained.

Je nach der gewünschten Länge des herzustellenden Wandabschnittes werden die benötigte Zahl von Paaren der nach Fig. 5 angeordneten Elemente E1 der Reihe nach nebeneinander aufgestellt, u.zw. so, daß,wie aus Fig. 20 erkenntlich ist, die die Vertikalbewehrung bildenden Stäbe 9 zueinander im Raster und in im wesentlichen gleichem Abstand zu liegen kommen. Danach werden an die Außenseiten der so gebildetne Vertikalbewehrung die Stabschar elemente 10 übereinander angeordnet, wie es schematisch in Fig. 20 dargestellt ist, und dann in üblicher Weise daran festgelegt, z.B. durch Rödeln. Die so fertiggestellte Bewehrung, bei der dann natürlich die Stäbe 11 und die Mittelteile 6 jeweils in einer gemeinsamen Ebene liegen, ist nun, innerhalb einer (in Fig. 20 nicht dargestellten) Schalung, betonbereit.Depending on the desired length of the wall section to be produced, the required number of pairs of the elements E1 arranged according to FIG. 5 are set up next to one another in sequence, etc. such that, as can be seen from FIG. 20, the bars 9 forming the vertical reinforcement come to lie in a grid and at substantially the same distance from one another. Then the coulters are attached to the outside of the vertical reinforcement elements 10 arranged one above the other, as shown schematically in Fig. 20, and then fixed to it in the usual way, for example by toiling. The reinforcement thus finished, in which the rods 11 and the middle parts 6 are of course each in a common plane, is now ready for concrete within a formwork (not shown in FIG. 20).

Eine ähnliche Darstellung ist in Fig. 21 ersichtlich, mit dem Unterschied, daß hier, entlang der Schalung S, anstelle der Elemente E1 nach Fig. 6 die Elemente E3.1 nach Fig. 17 zum Einsatz gelangen. Zur Verdeutlichung sind hier die Bügel, deren Mittelteile unten liegen, in vollen Linien dargestellt. Man erkennt, wie gemäß der Ausbildung nach den Fig. 6 bis 9 (Freihaltung des dem Eckstab 9 am Mittelteil 6 benachbarten Kreuzungspunktes im Raster) sich hier ein geschlossenes System von Stäben 9, 9a,9b der Vertikalbewehrung ergibt, jeden Kreuzungspunkt des Rasters einnehmend, unter voller Aufrechterhaltung der Knicksicherung in den mit A-A bezeichneten Ebenen durch die Halbbügel 5'.A similar representation can be seen in FIG. 21, with the difference that here, along the formwork S, instead of the elements E1 according to FIG. 6, the elements E3.1 according to FIG. 17 are used. For clarification, the brackets, the middle parts of which are below, are shown in full lines. It can be seen how, according to the design according to FIGS. 6 to 9 (keeping the crossing point adjacent to the corner bar 9 on the central part 6 in the grid), a closed system of bars 9, 9a, 9b of the vertical reinforcement results, taking each crossing point of the grid, with full maintenance of the kink protection in the planes denoted AA by the half-bars 5 '.

Vergleicht man die gemäß der Erfindung herstellbare Bewehrung nach den Fig. 20, 21 mit jener nach den Fig. 1 und 2 angefertigten, so erkennt man, daß hier mit einem Paar von untereinander gleichen Elementen 4, E1 bis E4 bzw. E1 und E2.1 bis E4.1 und weiteren, unter sich gleichen Bewehrungsteilen 10 die gewünschte Bewehrung erhältlich ist, wobei die Schenkel 7, 7' der Bügel 5 bzw. Halbbügel 5' die Funktion des bisherigen S-Hakens 3 (Fig. 1,2) als Knicksicherung übernehmen.Comparing the reinforcement according to the invention shown in FIGS. 20, 21 with that made according to FIGS. 1 and 2, you can see that here with a pair of mutually identical elements 4, E1 to E4 or E1 and E2. 1 to E4.1 and other reinforcement parts 10 which are the same, the desired reinforcement is available, the legs 7, 7 'of the bracket 5 or half bracket 5' being the function of the previous S-hook 3 (FIGS. 1, 2) Take over kink protection.

In den Fig. 22 bis 25 ist ersichtlich, wie eine Deckenbewehrung mit der erfindungsgemäßen Bewehrung herstellbar ist.22 to 25 show how a ceiling reinforcement can be produced with the reinforcement according to the invention.

Ausgehend von einer ersten Reihe nebeneinander, dem Grundriß der Decke entsprechend angeordneten, ähnlich dem Element 10 in Fig. 19 ausgebildeten Stabscharelementen E, ebenfalls bestehend je aus Längsstäben 11 und Querstäben 12, wie in den Fig. 22 und 23 dargestellt, werden auf die den Querstäben 12 abgekehrte Seite dieser Elemente E paarweise erfindungsgemäß angeordnete Bewehrungselemente E2 aufgelegt und mit den Elementen E verbunden, wie aus dem rechten Teil der Fig. 25 hervorgeht. Die zugehörige Draufsicht in der Pfeilrichtung Pf der Fig. 25 stellt die Fig. 24 dar. Dann wird, wie im linken Teil dieser Fig. 25 dargestellt, eine zweite Reihe von Elementen E, mit ihren Längsstäben 11 parallel zu jener der ersten Reihe, angeordnet, im Pfeilsinne Pf der Fig. 25 an die Bewehrungselemente E2 angelegt und mit diesen verbunden, wodurch man die fertige Deckenbewehrung erhält.Starting from a first row next to each other, arranged according to the floor plan of the ceiling, similar to element 10 in Fig. 19 trained bar coulter elements E, also consisting of longitudinal bars 11 and cross bars 12, as shown in FIGS. 22 and 23, on the The side of these elements E facing away from the cross bars 12 is placed in pairs of reinforcement elements E2 according to the invention and connected to the elements E, as can be seen from the right part of FIG. 25. The corresponding plan view in the arrow direction Pf of FIG. 25 is shown in FIG. 24. Then, as shown in the left part of this FIG. 25, a second row of elements E is arranged with its longitudinal bars 11 parallel to that of the first row 25, in the arrow direction Pf of FIG. 25, placed on the reinforcement elements E2 and connected to them, whereby the finished ceiling reinforcement is obtained.

Im Rahmen der Erfindung sind weitere Abänderungen an den beschriebenen Ausführungsbeispielen möglich.Within the scope of the invention, further modifications to the exemplary embodiments described are possible.

So könnten z.B. an der Stelle der Stabscharelemente 10 nach Fig. 19 auch Einzelstäbe oder Baustahlgewebematten als Längsbewehrung vorgesehen werden, die dann mit den Bewehrungselementen zusammensetzbar sind.For example, 19 individual bars or structural steel mesh mats can also be provided as longitudinal reinforcement at the location of the bar coulter elements 10, which can then be assembled with the reinforcement elements.
