    • Anhand der Figuren 1 bis 3 wird die Ausgestaltung des erfindungsgemässen Armierungs-Distanzhalters näher erläutert. Der aus Hart-PVC gefertigte Armierungs-Distanzhalter besteht aus einer Profilschiene 1, die ein H-förmiges Profil aufweist. Die Profilschiene 1 weist ein erstes oberes Schenkelpaar 2 und ein zweites unteres Schenkelpaar 5 sowie einen dazwischen liegenden Steg 8 auf. Beide Schenkel 3, 4 des oberen Schenkelpaars 2 sind in regelmässigen Abständen mit wechselweise angeordneten Ausnehmungen 10, 11 unterschiedlicher Dimension versehen, wobei jeweils zwei gleiche Ausnehmungen 10a,10b; 11a, 11b (Fig. 3) einander fluchtend gegenüberliegen, so dass sich ein in einander gegenüberliegenden Ausnehmungen aufgenommenes Armierungseisen im rechten Winkel zur Längsachse L des Armierungs-Distanzhalters erstreckt. Die Tiefe t der Ausnehmungen 10, 11 ist dabei grösser als der Radius r der aufzunehmenden Armierungseisen 21, 22 und die Öffnungsweite b ist kleiner als der Durchmesser der aufzunehmenden Armierungseisen 21, 22, so dass die zu verlegenden Armierungseisen 21, 22 unter Klemmwirkung in den genannten Ausnehmungen 10, 11 fixierbar sind. Zur Erzeugung dieser Klemmwirkung ist jeweils eines der an die Ausnehmungen 10, 11 angrenzenden Seitenteile 13, 14 federelastisch ausgebildet. Das jeweils andere der an die Ausnehmungen 10, 11 angrenzenden Seitenteile 15, 16 ist weitgehend biegesteif ausgebildet und überragt das federnde Seitenteil 13, 14 in der Höhe. Zwischen gleichartigen Ausnehmungen hat sich ein Abstand von 5 cm als sehr vorteilhaft erwiesen.The design of the reinforcing spacer according to the invention will be described with reference to FIGS. 1 to 3 explained in more detail. The hard-PVC reinforced spacer consists of a rail 1, which has an H-shaped profile. The profile rail 1 has a first upper leg pair 2 and a second lower leg pair 5 and an intermediate web 8 on. Both legs 3, 4 of the upper Pair of legs 2 are arranged at regular intervals with alternately Recesses 10, 11 provided different dimension, with two identical Recesses 10a, 10b; 11a, 11b (Fig. 3) are aligned with each other, so that a received in opposing recesses reinforcing iron extends at right angles to the longitudinal axis L of Armierungs-spacer. The depth t of the recesses 10, 11 is greater than the radius r of the male Reinforcing bars 21, 22 and the opening width b is smaller than the Diameter of the male reinforcing bars 21, 22, so that the to be laid Reinforcing iron 21, 22 under clamping action in said recesses 10, 11 are fixable. To generate this clamping effect is in each case one of the recesses 10, 11 adjacent side parts 13, 14 formed resiliently. The each other of the recesses 10, 11 adjacent side parts 15, 16 is formed largely rigid and surmounted the resilient side part 13, 14 in the Height. Between similar recesses, a distance of 5 cm has been considered very proved advantageous.

    Die beiden Schenkel 6, 7 des unteren Schenkelpaars 5 sind ebenfalls in regelmässigen Abständen mit wechselweise angeordneten Ausnehmungen 18, 19 unterschiedlicher Dimension versehen, wobei der wesentliche Unterschied zu den Ausnehmungen 10, 11 in den oberen Schenkeln 3, 4 darin zu sehen ist, dass die Ausnehmungen in den oberen Schenkeln 3, 4 gegenüber denjenigen in den unteren Schenkeln 6, 7 unterschiedlich dimensioniert sind. Dies hat den Vorteil, dass das Profil beidseitig verwendet werden kann und so insgesamt Ausnehmungen 10, 11, 18, 19 mit vier unterschiedlichen Dimensionen zur Verfügung stehen. Im vorliegenden Fall sind die Ausnehmungen zur Aufnahme von Armierungseisen 21, 22, 23, 24 mit einem Durchmesser von 8, 10, 12 und 14 mm ausgebildet. Natürlich können auch Ausnehmungen zur Aufnahme von Armierungseisen mit anderen Durchmessern vorgesehen werden.The two legs 6, 7 of the lower leg pair 5 are also in regular Distances with alternately arranged recesses 18, 19 different Dimension provided, with the essential difference from the recesses 10, 11th in the upper legs 3, 4 can be seen therein that the recesses in the upper Legs 3, 4 compared to those in the lower legs 6, 7 different are dimensioned. This has the advantage that the profile can be used on both sides can and so total recesses 10, 11, 18, 19 with four different ones Dimensions are available. In the present case, the recesses are for Inclusion of reinforcing bars 21, 22, 23, 24 with a diameter of 8, 10, 12 and 14 mm. Of course, also recesses for receiving reinforcing iron be provided with other diameters.

    Durch den Abstand zwischen dem Boden der Ausnehmungen 10, 11 und den eine Auflagefläche F aufweisenden unteren Seitenteile 25, 26 wird der Abstand der Armierungseisen 21, 22 bezüglich der Schalung bestimmt. Im vorliegenden Fall beträgt dieser Abstand ca. 3 cm. Dieser Abstand wird auch dann eingehalten, wenn der Armierungs-Distanzhalter um 180° um seine Längsachse gedreht eingesetzt wird. In diesem Fall können in den Ausnehmungen 18, 19 Armierungseisen 23, 24 fixiert werden und die Seitenteile 15, 16 kommen an der Schalung zur Auflage.By the distance between the bottom of the recesses 10, 11 and the one Support surface F having lower side portions 25, 26 is the distance of the reinforcing bars 21, 22 determined with respect to the formwork. In the present case this is Distance about 3 cm. This distance is maintained even when the reinforcement spacer is used rotated by 180 ° about its longitudinal axis. In this case can be fixed in the recesses 18, 19 reinforcing bars 23, 24 and the Side parts 15, 16 come to the formwork for circulation.

    Wie aus der Fig. 3 ersichtlich ist, ist der Steg 8 mit Ausnehmungen 30 für den Durchfluss des Betons versehen. Zwischen zwei Ausnehmungen 30 ist jeweils eine Bohrung 31 zur Aufnahme von Befestigungsmitteln wie Nägeln in den Steg 8 eingelassen. Mittels solchen Befestigungsmitteln kann das Profil 1 auch an einer vertikal verlaufenden Schalung sicher befestigt werden.As can be seen from Fig. 3, the web 8 with recesses 30 for the flow of the concrete. Between two recesses 30 is in each case a bore 31 for receiving fasteners such as nails embedded in the web 8. through such fasteners, the profile 1 also on a vertically extending Shuttering be securely fastened.

    Derartige Profilschienen 1 eignen sich deshalb speziell für vertikal oder schräg zu verlegende Lagen von Armierungseisen, wie sie beispielsweise für Betonwände zum Einsatz kommen. Gegenüber den bisher eingesetzten Armierungs-Distanzhaltem ergeben sich eine ganze Reihe von Vorteilen. Indem die Armierungseisen unter Klemmwirkung in einem Schenkelpaar 2, 5 fixiert werden, wird zum einen eine sichere Fixierung der Armierungseisen in der Profilschiene 1 gewährleistet und zum anderen wird den Armierungseisen der Winkel gegenüber der Profilschiene 1 vorgegeben, so dass sie ohne zusätzliche Hilfsmittel problemlos im Lot verlegt werden können, sofern die Profilschiene horizontal ausgerichtet und an der Schalung fixiert wurde. Eine sichere Fixierung ohne zusätzliche Hilfsmittel wie beispielsweise ein Bindedraht ist insofern wichtig, damit die Armierungseisen sicher in ihrer vertikalen Lage gehalten werden, ohne dass die Gefahr besteht, dass sie herauskippen. Indem jedes Schenkelpaar 2; 5 mit zwei unterschiedlichen Ausnehmungen 10, 11; 18, 19 versehen ist, kann ein und dieselbe Profilschiene 1 für vier Armierungseisen 21, 22, 23, 24 mit unterschiedlichen Durchmessern eingesetzt werden. Anstelle der hier dargestellten Ausführungsform mit zwei unterschiedlichen Ausnehmungen 10, 11; 18, 19 pro Schenkelpaar 2, 5 sind durchaus auch Varianten denkbar, die drei oder mehr Ausnehmungen unterschiedlicher Grösse aufweisen. Dies hängt zum einen vom absoluten Durchmesser der aufzunehmenden Armierungseisen ab und zum anderen vom Rasterabstand zwischen gleichartigen Ausnehmungen. Ein Rasterabstand von 5 cm hat sich insofern bewährt, da auf diese Weise praktisch alle in der Praxis vorgegebenen Abstandsraster realisierbar sind.Such rails 1 are therefore particularly suitable for vertically or obliquely to be laid Layers of reinforcing iron, as used for example for concrete walls come. Compared to the previously used Armierungs Distanzhaltem a whole series of advantages. By the reinforcing iron under clamping action be fixed in a leg pair 2, 5, on the one hand a secure fixation of Arming iron guaranteed in the rail 1 and the other is the reinforcing iron the angle with respect to the rail 1 specified so that they without Additional tools can be easily laid in the Lot, if the rail aligned horizontally and fixed to the formwork. A secure fixation without additional aids such as a binding wire is important in this respect, so that the reinforcing bars are securely held in their vertical position without that there is a danger that they will tip out. By each leg pair 2; 5 with two different recesses 10, 11; 18, 19 can be one and the same Profile rail 1 for four reinforcing bars 21, 22, 23, 24 with different diameters be used. Instead of the embodiment shown here with two different recesses 10, 11; 18, 19 per pair of legs 2, 5 are quite also variants conceivable, the three or more recesses of different sizes exhibit. This depends on the one hand on the absolute diameter of the male Reinforcing iron from and to the other of the grid spacing between similar recesses. A grid spacing of 5 cm has proven itself in this way practically all distance grids specified in practice can be realized.

    Fig. 4 zeigt eine alternative Ausführungsform eines Armierungs-Distanzhalters in einer Seitenansicht. Nebst Ausnehmungen 11, in denen Armierungseisen in der vorgängig beschriebenen Weise unter Klemmwirkung aufgenommen werden können, sind bei diesem Ausführungsbeispiel auch noch Ausnehmungen 33 vorgesehen, welche sich insbesondere zur Aufnahme von horizontal zu verlegenden Armierungseisen eignen. Die Ausnehmungen 33 eignen sich zudem zur Aufnahme von Armierungseisen 34, 35 mit unterschiedlichem Durchmesser. Ein solcher Armierungs-Distanzhalter kann daher sowohl zum horizontalen Verlegen einer Lage von Armierungseisen und alternativ auch zum vertikalen Verlegen einer Lage von Armierungseisen eingesetzt werden.Fig. 4 shows an alternative embodiment of a reinforcing spacer in one Side view. In addition to recesses 11, in which rebars in the previous described manner can be included under clamping action, are in this Embodiment also provided recesses 33, which in particular suitable for horizontal reinforcing iron to be laid. The Recesses 33 are also suitable for receiving reinforcing bars 34, 35 with different diameter. Such a reinforcing spacer can therefore both for horizontal laying of a layer of reinforcing iron and alternatively also used for vertical laying of a layer of reinforcing iron.

    Fig. 5 zeigt eine weitere, alternative Ausführungsform eines Armierungs-Distanzhalters in einer Seitenansicht. Der Armierungs-Distanzhalter weist wiederum eine H-förmig gestaltet Profilschiene 38 mit einem Steg 41, einem ersten oberen Schenkelpaar 39 und einem zweiten unteren Schenkelpaar 40 auf. Sowohl in das obere wie auch in das untere Schenkelpaar 39, 40 sind wechselweise Ausnehmungen 42, 43, 44, 45 unterschiedlicher Dimension eingelassen, so dass insgesamt vier Grössen von Armierungseisen darin fixierbar sind. Zusätzlich sind im einen Schenkelpaar 39 beidseits der Ausnehmungen 42, 43 Bohrungen 47, 48 vorgesehen, in welchen Klemmelemente 50 mittels Rastnocken 51, 52 fixierbar sind. Die Klemmelemente 50 werden vorzugsweise über den grössten Ausnehmungen 42 angebracht. Das Klemmelement 50 selber weist eine Ausnehmung 53 auf, die zur klemmenden Aufnahme von Armierungseisen vorgesehen ist, die einen kleineren Durchmesser besitzen als die in der Ausnehmungen 42 zu fixierenden Armierungseisen. Eine mögliche Dimensionierung des Armierungs-Distanzhalters könnte beispielsweise darin bestehen, dass in die Profilschiene 38 Ausnehmungen 42, 43, 44, 45 zum Fixieren von Armierungseisen mit Durchmessern von 16, 14, 12 und 10mm eingelassen sind, währenddem unterschiedlich dimensionierte Klemmelemente 50 zum Fixieren von Armierungseisen mit Durchmessern von beispielsweise 8 und 6mm vorgesehen sind. Das heisst mit anderen Worten, die Klemmelemente 50 brauchen nur dann eingesetzt zu werden, wenn "kleine" Armierungseisen mit einem Durchmesser von 8 oder 6mm im Armierungs-Distanzhalter fixiert werden müssen. Die üblichen Standardgrössen von 16, 14, 12 und 10mm können direkt in der Profilschiene 38 fixiert werden. Ein derartiger Armierungs-Distanzhalter ist daher sehr universell einsetzbar. Zur Aufnahme von Befestigungsmitteln wie Nägeln sind Bohrungen 54 in den Steg 41 eingelassen. Ausserdem ist der Steg 41 mit nicht näher dargestellten Ausnehmungen für den Durchfluss des Betons versehen. Fig. 5 shows a further, alternative embodiment of a reinforcing spacer in a side view. The reinforcement spacer again has an H-shaped design Profile rail 38 with a web 41, a first upper leg pair 39 and a second lower pair of legs 40. Both in the upper and in the lower Leg pair 39, 40 are alternately recesses 42, 43, 44, 45 different Dimension so that a total of four sizes of rebar can be fixed in it. In addition, in one leg pair 39 on both sides of the Recesses 42, 43 bores 47, 48 are provided, in which clamping elements 50th By means of locking cams 51, 52 are fixable. The clamping elements 50 are preferably attached over the largest recesses 42. The clamping element 50 itself points a recess 53, which provided for the clamping reception of reinforcing iron is that have a smaller diameter than that in the recesses 42nd to be fixed reinforcing iron. A possible dimensioning of the reinforcement spacer For example, could consist in that in the rail 38 recesses 42, 43, 44, 45 for fixing reinforcing iron with diameters of 16, 14, 12 and 10mm are embedded while the differently sized Clamping elements 50 for fixing reinforcing iron with diameters of, for example 8 and 6mm are provided. In other words, the clamping elements 50 need only be used if "small" reinforcing bars fixed with a diameter of 8 or 6mm in the reinforcement spacer have to. The usual standard sizes of 16, 14, 12 and 10mm can be found directly in the Profile rail 38 are fixed. Such a reinforcing spacer is therefore very universally applicable. For receiving fasteners such as nails are Holes 54 embedded in the web 41. In addition, the web 41 is not closer recesses provided for the flow of the concrete.

    Obwohl bei den vorgängigen Ausführungsbeispielen immer von Armierungs-Distanzhaltern mit H-förmigem Profil ausgegangen wurde, bei denen immer beide Schenkel eines Schenkelpaars mit paarweise fluchtenden Ausnehmungen versehen sind, sind durchaus auch Varianten von Armierungs-Distanzhaltem möglich, bei denen nur ein Schenkel eines Schenkelpaars zur Aufnahme von zu verlegenden Armierungseisen unter Klemmwirkung ausgebildet ist oder bei denen überhaupt nur ein Schenkel zur Aufnahme von zu verlegenden Armierungseisen unter Klemmwirkung vorgesehen ist.Although always in the previous embodiments of reinforcing spacers was assumed with H-shaped profile, where always both legs a pair of legs are provided with pairs aligned recesses are quite possibly variants of Armierungs Distanzhaltem possible, where only one Legs of a pair of legs for receiving reinforcing iron to be laid is formed under clamping action or in which at all only one leg to Inclusion of laying iron to be laid under clamping action is provided.

    Fig. 6 zeigt eine weitere, alternative Ausführungsform eines Armierungs-Distanzhalters in einer Seitenansicht. In diesem Fall ist eine U-förmig gestaltete Profilschiene 55 vorgesehen, die ein unteres Schenkelpaar 56 aufweist, das durch einen Steg 57 verbunden ist, der mit einer flachen Oberseite versehen ist. In diesen Steg 57 sind Bohrungen 58 eingelassen, die dem Befestigen von unterschiedlich dimensionierten, klammerartig ausgebildeten Klemmelementen 59, 60 dienen. Letztere sind dazu mit Rastnasen 61 versehen, die in die Bohrungen 58 eingeführt und darin festgehalten werden. Obwohl im Normalfall eine Rastnase 61 zum Fixieren eines Klemmelements 59, 60 in der Profilschiene 55 genügt, können die Klemmelemente 59, 60 auch mit zwei Rastnasen versehen werden, wobei in diesem Fall die Profilschiene 55 natürlich auch mit zwei entsprechenden Bohrungen versehen sein muss. Das Vorsehen von zwei Rastnasen hat den Vorteil, dass die Klemmelemente gegen Verdrehung gesichert sind. Auch bei diesem Ausführungsbeispiel ist der Steg 57 mit Bohrungen 62 zur Aufnahme von Befestigungsmitteln versehen. Es versteht sich, dass nebst den beiden dargestellten Klemmelementen 59, 60 noch eine Vielzahl von anderen, unterschiedlich gestalteten und/oder dimensionierten Klemmelementen zum Einsatz kommen kann. Auch bei diesem Ausführungsbeispiel ist der Steg 57 mit Ausnehmungen für den Durchfluss des Betons versehen, wobei diese nicht näher dargestellt sind.Fig. 6 shows a further, alternative embodiment of a reinforcing spacer in a side view. In this case, a U-shaped profiled rail 55 is provided, which has a lower pair of legs 56 connected by a web 57 is, which is provided with a flat top. In this web 57 are holes 58 inlaid, attaching differently sized, bracket-like trained clamping elements 59, 60 are used. The latter are with locking lugs 61st provided, which are inserted into the holes 58 and held therein. Although in the Normally, a locking lug 61 for fixing a clamping member 59, 60 in the rail 55 is sufficient, the clamping elements 59, 60 are also provided with two locking lugs be, in which case the rail 55 of course with two corresponding Drilling must be provided. The provision of two locking lugs has the Advantage that the clamping elements are secured against rotation. Also with this Embodiment, the web 57 with holes 62 for receiving fasteners Mistake. It is understood that, in addition to the two clamping elements shown 59, 60 still a variety of others, differently designed and / or dimensioned clamping elements can be used. Also with this Embodiment is the web 57 with recesses for the flow of the concrete provided, these are not shown in detail.
