Abstract

The spacer for reinforcement elements of concrete structures has a profiled load-bearing member (1) onto which a number of supports (6) are plugged. Each support (6) is of an A-shaped design in side view and has, in its upper part, a transverse web (7) in order to form a plug-through opening (8) for the load-bearing member (1). The load-bearing member (1) has a double-T profile having a web (2), at the foot end of which there is arranged a relatively wide foot beam (3) and on the upper half of which there is arranged a transverse beam (4) having a somewhat longer length than the inside width of the plug-through opening (8) at this point, and the head end (5) of which serves as bearing surface for the reinforcement elements. A spacer of this type has a high degree of stability and can be produced with a relatively low amount of outlay and material. Moreover, the upper part of the support serves as a stop for the accurate laying of the reinforcement elements. <IMAGE>

Description

Die vorliegende Erfindung bezieht sich auf einen Abstandhalter für Bewehrungselemente von Betonbauwerken gemäss Oberbegriff von Patentanspruch 1. Solche Abstandhalter werden gewöhnlich für das Erstellen von Betonüberdeckungen, beispielsweise Fussböden oder Decken, verwendet und dienen als Auflage für die Bewehrungseisen. Die Abstandhalter müssen eine sichere Abstützung der Bewehrungselemente bieten und sind insbesondere auch einer Trittbelastung beim Begehen der Bewehrung ausgesetzt. Die vielfach üblichen Abstandhalter aus Metall genügen immer weniger den strenger werdenden Anforderungen der Korrosionsbeständigkeit, so dass sich Abstandhalter aus Kunststoff immer mehr durchsetzen.The present invention relates to a spacer for reinforcement elements of concrete structures according to the preamble of claim 1. Such spacers are usually used for creating concrete coverings, for example floors or ceilings, and serve as a support for the reinforcing bars. The spacers must provide secure support for the reinforcement elements and are particularly exposed to treading when walking on the reinforcement. The widely used metal spacers are less and less able to meet the increasingly stringent requirements for corrosion resistance, so that plastic spacers are becoming increasingly popular.

Bei der Verwendung von Abstandhaltern aus Kunststoff gewinnt die Stabilität und die rationelle Fertigung der Teile immer mehr an Bedeutung. Aus der DE-U-90 00 367 ist ein Abstandhalter gemäss Oberbegriff von Patentanspruch 1 bekannt, der ganz aus Kunststoff besteht, und dessen Böcke an den T-Träger anklemmbar sind, wobei dies auch an Ort und Stelle geschehen kann. Einerseits begrenzt die elastische Ausspreizung des Kopfbereiches der Böcke die Auswahl des zu verwendenden Kunststoffes und andererseits bedingt das mögliche Anbringen der Böcke an Ort und Stelle eine Massein-teilung auf dem Träger, da sowohl die Böcke als auch die Bewehrungselemente möglichst gleichmässig verteilt werden müssen.When using plastic spacers, the stability and rational production of the parts are becoming increasingly important. From DE-U-90 00 367 a spacer according to the preamble of claim 1 is known, which is made entirely of plastic and whose trestles can be clamped to the T-beam, which can also be done on the spot. On the one hand, the elastic expansion of the head area of the trestles limits the choice of the plastic to be used, and on the other hand, the possible attachment of the trestles on site necessitates a graduation on the beam, since both the trestles and the reinforcement elements must be distributed as evenly as possible.

Es ist demgegenüber Aufgabe der vorliegenden Erfindung, einen Abstandhalter anzugeben, der bei hoher Standfestigkeit und hoher Trittbelastung rationell gefertigt werden kann. Diese Aufgabe wird mit dem Abstandhalter gemäss Patentanspruch 1 gelöst.In contrast, it is an object of the present invention to provide a spacer which can be efficiently manufactured with high stability and high tread load. This object is achieved with the spacer according to claim 1.

Bei vielen Betonbauwerken wird die Betonüberdeckung derart vergossen, dass die Unterseite der Abstandhalter sichtbar wird. Bei vielen Betonüberdeckungen, die nachher noch beschichtet werden, sei es durch einen Anstrich oder durch Mörtel oder dergleichen, spielt dies keine grosse Rolle, während dies bei Betonbauwerken, die nicht mehr beschichtet werden, nicht annehmbar ist. Davon ausgehend wird in einer Weiterausbildung der Erfindung der untere Teil des Bockes, bis zum Quersteg desselben, mit Beton umgossen.In many concrete structures, the concrete cover is poured in such a way that the underside of the spacers is visible. With many concrete coverings that are subsequently coated, whether by painting or mortar or the like, this does not play a major role, while this is unacceptable for concrete structures that are no longer coated. Based on this, in a further development of the invention, the lower part of the trestle, up to the crossbar thereof, is poured with concrete.

Die Erfindung wird im folgenden anhand einer Zeichnung von Ausführungsbeispielen näher erläutert.

  • Fig. 1 zeigt in perspektivischer Sicht einen Teil eines erfindungsgemässen Trägers,
  • Fig. 2 zeigt in perspektivischer Sicht einen erfindungsgemässen Bock,
  • Fig. 3 zeigt einen Schnitt durch eine Seitenwand des Bockes von Fig. 2,
  • Fig. 4 zeigt in perspektivischer Sicht den durch einen Bock gesteckten Träger, und
  • Fig. 5 zeigt ein zweites Ausführungsbeispiel eines erfindungsgemässen Bockes.
The invention is explained below with reference to a drawing of exemplary embodiments.
  • 1 shows a perspective view of part of a carrier according to the invention,
  • 2 shows a trestle according to the invention in a perspective view,
  • 3 shows a section through a side wall of the trestle of FIG. 2,
  • Fig. 4 shows a perspective view of the carrier inserted through a trestle, and
  • 5 shows a second exemplary embodiment of a trestle according to the invention.

Der Träger 1 gemäss Fig. 1 besitzt ein Doppel-T-Profil, wobei dieser Träger in Fig. 1 auf den Kopf gestellt dargestellt ist und auch so verwendet wird. Dieses Doppel-T-Pro-fil besteht aus einem Steg 2, an dessen Fussende der breitere Fussbalken 3 und in dessen oberen Hälfte der schmälere Querbalken 4 angeordnet ist. Das Kopfende 5 des Steges bildet die Auflage für die Bewehrungselemente. Der Träger 1 kann rationell aus einem geeigneten Kunststoff hergestellt werden.The carrier 1 according to FIG. 1 has a double-T profile, this carrier being shown upside down in FIG. 1 and also being used in this way. This double-T profile consists of a web 2, at the foot end of which the wider foot beam 3 and in the upper half of the narrower cross beam 4 is arranged. The head end 5 of the web forms the support for the reinforcement elements. The carrier 1 can be efficiently made from a suitable plastic.

Gemäss Fig. 2 hat der Bock 6, von der Seite aus gesehen, die Form eines grossen A und weist etwa in seiner Mitte einen Quersteg 7 auf, wodurch der obere Teil des Bockes eine Durcksteck-Oeffnung 8 für den Träger 1 bildet. Sowohl der Fussbalken 3 als auch der Querbalken 4 weisen eine der Durcksteck-Oeffnung 8 angepasste Länge auf, wobei der Querbalken 4 eine etwas grössere Länge aufweist als die lichte Weite der Durchsteck-Oeffnung 8 an dieser Stelle. Dadurch wird eine Klemmwirkung erzielt, die das freie Verschieben des Bockes auf dem Träger verhindert, aber andererseits ein Aufstecken ohne zu grossen Widerstand ermöglicht. Eine weitere Erleichterung des Aufsteckens der Böcke, das automatisch erfolgen kann, wird dadurch gewährleistet, dass die Oberseite 9 der drei Wände 7 und 13 der Durchsteck-Oeffnung, siehe Fig. 3, nicht eben ist, sondern, in Längsrichtung des Trägers gesehen, zu den beiden Aussenseiten des Bockes hin abfällt.2, the trestle 6, seen from the side, has the shape of a large A and has a crosspiece 7 approximately in its center, as a result of which the upper part of the trestle forms a push-through opening 8 for the support 1. Both the foot bar 3 and the cross bar 4 have a length adapted to the push-through opening 8, the cross bar 4 being somewhat longer than the clear width of the push-through opening 8 at this point. This achieves a clamping effect that prevents the trestle from moving freely on the carrier, but on the other hand enables it to be attached without excessive resistance. A further easing of the mounting of the trestles, which can take place automatically, is ensured by the fact that the upper side 9 of the three walls 7 and 13 of the push-through opening, see FIG. 3, is not flat, but rather, seen in the longitudinal direction of the carrier the two outside sides of the trestle.

Dem Quersteg 7 schliessen sich nach unten hin zwei Füsse 10 an, die in vorliegendem Ausführungsbeispiel je eine Mittelwand 11 aufweisen, um die Stabilität zu erhöhen. Der Erhöhung der Stabilität dient ferner ein Verbindungssteg 12 zwischen den beiden Füssen. Diese Hohlkastenkontruktion mit Verstrebungen des Bockes ergibt eine hohe Stabilität einerseits und erlaubt eine Materialersparnis andererseits.The crossbar 7 is adjoined at the bottom by two feet 10, each of which has a central wall 11 in the present exemplary embodiment in order to increase the stability. A connection web 12 between the two feet also serves to increase the stability. This hollow box construction with bracing of the trestle results in a high stability on the one hand and allows material to be saved on the other.

Im vorliegenden Ausführungsbeispiel gemäss den Fig. 1 bis 3 wurde ein bestimmter Abstandhalter mit einem bestimmten Abstand zwischen den nicht eingezeichneten Schalenbrettern und den nicht eingezeichneten Bewehrungselementen dargestellt, derart, dass die Durchsteck-Oeffnung 8 und die Füsse ungefähr die gleiche Höhe aufweisen. Selbstverständlich gibt es auf dem Bauwesen verschiedene Abstände einzuhalten, wobei für den vorliegenden Abstandhalter jeweils der gleiche Träger für sämtliche Abstände zwischen Schalung und Bewehrungselementen gewählt werden kann, was eine gleiche Durchsteck-Oeffnung 8 bedingt, während die Länge der Füsse 10 in den gewünschten und erforderlichen Längen hergestellt werden kann, um die im allgemeinen genormten Höhen der Abstandhalter herzustellen. Durch die besonders stabile Konstruktion der Böcke ist es möglich, dafür wiederverwertbaren Kunststoff zu verwenden.In the present exemplary embodiment according to FIGS. 1 to 3, a certain spacer with a certain distance between the not shown shell boards and the not shown reinforcement elements was shown in such a way that the push-through opening 8 and the feet have approximately the same height. Of course there are different distances to keep in the building industry, whereby for the present spacer the same support can be chosen for all the distances between the formwork and reinforcement elements, which requires the same through opening 8, while the length of the feet 10 can be produced in the desired and required lengths by the generally standardized To produce heights of the spacers. Due to the particularly stable construction of the trestles, it is possible to use recyclable plastic.

In Fig. 4 sind zwei Böcke auf einen Träger aufgesteckt und man ersieht daraus, dass das Umfassen der Träger mit der Durchsteck-Oeffnung der Böcke eine genaue Verlegung der Bewehrungselemente ergibt, denn dadurch, dass die Böcke in der Fabrik in einem genauen Abstand D voneinander aufgesteckt werden, ergibt sich ein genaues Rastermass für die Bewehrungselemente, dessen Verlegung noch dadurch erleichtert wird, dass die Oberseite 14 der Böcke einen Anschlag bilden.In Fig. 4 two trestles are plugged onto a beam and it can be seen from this that the encircling of the beams with the push-through opening of the trestles results in an exact laying of the reinforcement elements, because the trestles in the factory are at a precise distance D from one another are plugged on, there is an exact grid dimension for the reinforcement elements, the laying of which is made even easier by the fact that the top 14 of the trestles form a stop.

Wie bereits eingangs erwähnt wurde, gibt es Bauwerke, bei denen die Sicht des Unterteils der Böcke nicht erwünscht oder nicht erlaubt ist. Für diese Fälle wird gemäss dem Ausführungsbeispiel von Fig. 5 der untere Teil des Bockes 15 mit Beton 16 um- und ausgegossen. Dieser Beton ermöglicht nicht nur eine sehr gute Verbindung zwischen dem Abstandhalter und dem Betonbauwerk, sondern auch eine weitgehende Anpassung an das Betonbauwerk, um die Unterseite des Abstandhalters wenig bis gar nicht vom zu erstellenden Bauwerk zu unterscheiden. Abgesehen von diesen Vorteilen weist ein Abstandhalter mit Böcken mit einem Betonunterteil eine noch weitere Sicherheit gegenüber erhöhter Trittbelastung auf.As already mentioned at the beginning, there are structures in which the view of the lower part of the trestles is not desired or not permitted. For these cases, the lower part of the trestle 15 is cast and poured with concrete 16 according to the embodiment of FIG. 5. This concrete not only enables a very good connection between the spacer and the concrete structure, but also an extensive adaptation to the concrete structure in order to differentiate little or not at all from the underside of the spacer from the structure to be created. Apart from these advantages, a spacer with trestles with a concrete lower part offers even more security against increased tread load.
