Description

Die Erfindung betrifft eine Distanzhaltevorrichtung für Stahlbeton-Konstruktionen gemäss dem Obergriff des Anspruchs 1.The invention relates to a spacer device for reinforced concrete structures according to the preamble of claim 1.

Distanzhaltevorrichtung, wie sie für Stahlbeton-Konstruktionen in grossem Umfang verwendet werden, dienen als Hilfsmittel zur genauen Verlegung von Einzelstab- und Netz-Bewehrungsanlagen. Hierbei haben sie bei Stahlbeton-Decken und -Platten die obere Bewehrungsanlage auf der verlangten Höhe zu halten, während sie in Stahlbeton-Wänden die innern und äussern Bewehrungslagen zu fixieren haben. Zudem können an den Distanzhaltevorrichtungen Einlagen verschiedener Art befestigt werden. Es ist somit mit diesen Vorrichtungen möglich, eine genau definierte Lage in einer Stahlbeton-Konstruktion und/oder zwischen zwei Bewehrungsanlagen einzuhalten.Spacers, such as those used on a large scale for reinforced concrete structures, serve as aids for the precise laying of single-bar and mesh reinforcement systems. In the case of reinforced concrete ceilings and slabs, they have to keep the upper reinforcement system at the required height, while they have to fix the inner and outer reinforcement layers in reinforced concrete walls. In addition, various types of inserts can be attached to the spacers. It is therefore possible with these devices to maintain a precisely defined position in a reinforced concrete construction and / or between two reinforcement systems.

Bekannte Distanzhaltevorrichtungen werden mit und ohne Stützfüsse, die meistens aus Kunststoff hergestellt sind, ausgerüstet. Mit Kunststoff ausgerüstete Vorrichtungen werden beim Erstellen von Deckenbewehrungen nach dem Verlegen der unteren Bewehrungslagen direkt auf die Schalung gestellt und bilden hierbei das Traggerippe für die obere Bewehrung. Die aus Kunststoff gefertigten Stützfüsse verhindern das Rosten im Bereich der Aufstützpunkte der Schalung.Known spacers are equipped with and without support feet, which are usually made of plastic. With Devices equipped with plastic are placed directly on the formwork when laying the ceiling reinforcement after laying the lower reinforcement layers and form the supporting structure for the upper reinforcement. The plastic support feet prevent rusting in the area of the support points of the formwork.

Distanzhaltevorrichtungen ohne Stützfüsse werden beispielsweise beim Erstellen von Deckenbewehrungen nach dem Verlegen der unteren Bewehrungslagen auf diese Lagen gestellt und bilden das Traggerippe für die obere Bewehrung. Durch ihren Aufbau mit durchlaufenden Längsträgern sowohl im Scheitelbereich als auch im Bereich der Schenkel sind sie auch zum Einsatz in Stahlbeton-Wänden geeignet. Dort werden sie zur Erleichterung des Einbringens des Betons vorzugsweise in senkrechter Lage angeordnet.Spacers without support feet are placed on these layers, for example when creating ceiling reinforcement after laying the lower reinforcement layers, and form the supporting structure for the upper reinforcement. Due to their construction with continuous side members both in the apex area and in the area of the legs, they are also suitable for use in reinforced concrete walls. There they are preferably arranged in a vertical position to facilitate the introduction of the concrete.

Die Distanzhaltevorrichtungen werden immer quer zum Verlauf der in der Stahlbeton-Konstruktion auftretenden Zugspannungen angeordnet. Sie bilden somit kein tragendes Element, doch ist ihre Funktion wesentlich, damit die mehrlagige Bewehrung in Wänden, Platten und Decken zuverlässig fixiert ist.The spacers are always arranged transversely to the course of the tensile stresses occurring in the reinforced concrete construction. They do not form a load-bearing element, but their function is essential so that the multi-layer reinforcement in walls, slabs and ceilings is reliably fixed.

Die Distanzhaltevorrichtungen haben eine bestimmte Stabilität aufzuweisen, da sie das Gewicht der auf denselben abgestützten Bewehrungsanlage zu tragen haben, jedoch können noch zusätzliche Beanspruchungen auftreten, beispielsweise dadurch, dass Personen die Distanzhaltevorrichtung begehen. Da die Distanzhaltevorrichtungen im allgemeinen nicht stärker dimensioniert werden, als dies für ihre Funktion in der Stahlbeton-Konstruktion erforderlich ist, können durch diese zusätzlichen Beanspruchungen Beschädigungen an den Distanzhaltevorrichtungen entstehen und es kann dadurch ihr Ersatz erforderlich werden.The spacers have a certain stability because they have to bear the weight of the reinforcement system supported on them, but additional stresses can occur, for example, because people walk on the spacer. Since the spacer devices are generally not dimensioned more than is required for their function in the reinforced concrete construction, these additional stresses can damage the spacer devices and may therefore require their replacement.

Bei einer bekannten Distanzhaltevorrichtung (CH-A-486 617) bestehen die Abstandhalter aus bügelförmigen Haltern mit Stützfüssen, z.B. aus Kunststoff oder Beton, während im Scheitel des Steges an dem Halter ein einziger Längsträger angeordnet ist, der an den Haltern durch Schweissen befestigt ist. Zur Vergrösserung der Schweissstelle ist die Auflagestelle für die Längsträger konkav ausgebildet, wodurch jedoch die Stabilität der Distanzhaltevorrichtung nicht wesentlich verbessert wird.In a known spacer device (CH-A-486 617) the spacers consist of bow-shaped holders with support feet, e.g. made of plastic or concrete, while in the apex of the web a single longitudinal member is arranged on the holder, which is fastened to the holders by welding. In order to enlarge the welding point, the support point for the side members is concave, but this does not significantly improve the stability of the spacer device.

Bei einer weiteren bekannten Distanzhaltevorrichtung (EP-A-0 176 815) wird eine Erhöhung der Stabilität entweder durch die Verwendung von zwei Längsträgern im Scheitelbereich des Steges der Halter oder durch je einen an den Schenkeln angeordneten Längsträger verbessert. Nachteilig ist jedoch bei der erstgenannten Ausführungsform, dass die beiden Längsträger verhältnismässig stark ausgebildet sein müssen, während bei der zweiten Ausführungsform der Nachteil besteht, dass solche Distanzhaltevorrichtungen beim Stapeln verhältnismässig viel Platz benötigen, da die an den Schenkeln angeordneten Längsträger ein vollständiges Ineinanderschieben der gestapelten Distanzhaltevorrichtungen verunmöglichen.In another known spacer device (EP-A-0 176 815) an increase in stability is improved either by the use of two side members in the apex region of the web of the holder or by one side member each arranged on the legs. However, a disadvantage of the first-mentioned embodiment is that the two side members have to be relatively strong, while in the second embodiment there is the disadvantage that such spacer devices require a relatively large amount of space when stacking, since the side members arranged on the legs completely push the stacked spacer devices into one another render impossible.

Eine gattungsgemässe Distanzhaltevorrichtung ist auch aus DE-U-7 412 784 bekannt. Auch hier sind seitliche Längsträger im Bereich der Schenkelenden angebracht, sodass die Stapeleigenschaften der Distanzhaltevorrichtung beeinträchtigt sind.A generic spacer device is also known from DE-U-7 412 784. Here, too, longitudinal side members are attached in the region of the leg ends, so that the stacking properties of the spacer device are impaired.

Aufgabe der Erfindung war es, eine gattungsgemässe Distanzhaltevorrichtung derart zu verbessern, dass sie günstige Stapeleigenschaften aufweist, sie aber zugleich so auszubilden, dass sie eine ausreichende Festigkeit insbesondere gegen Biegungen um Querachsen aufbringt.The object of the invention was to improve a generic spacer device in such a way that it has favorable stacking properties, but at the same time to design it in such a way that it has sufficient strength, in particular against bending about transverse axes.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is achieved by the characterizing features of claim 1.

Die Erfindung ist in der Zeichnung in einem Ausführungsbeispiel dargestellt und nachfolgend beschrieben. Es zeigen:

Fig. 1
einen schematisch dargestellten Querschnitt einer Distanzhaltevorrichtung mit drei Längsträgern und Stützfüssen an den Schenkeln,
Fig. 2
eine schematisch dargestellte Distanzhaltevorrichtung mit drei Längsträgern im Stegbereich in räumlicher Darstellung, und
Fig. 3
einen Querschnitt von zwei ineinandergestapelten Distanzhaltevorrichtungen.
The invention is shown in the drawing in one embodiment and described below. Show it:
Fig. 1
2 shows a schematically illustrated cross section of a spacer device with three longitudinal beams and support feet on the legs,
Fig. 2
a schematically illustrated spacer with three longitudinal members in the web area in a spatial representation, and
Fig. 3
a cross section of two stacked spacers.

Aus dem Querschnitt einer Distanzhaltevorrichtung nach Fig. 1 ist ersichtlich, dass der Halter 1 einer Distanzhaltevorrichtung 2 U-förmig ausgebildet ist und sich aus zwei Schenkeln 3 und einem Steg 4 zusammensetzt. An den freien Enden der Schenkel 3 sind Stützfüsse 5 befestigt, die beispielweise aus Kunststoff oder Beton hergestellt sind. Die Stützfüsse 5 werden nur dann an den Schenkeln befestigt, wenn die Distanzhaltevorrichtung auf einer Schalung abgestützt wird.It can be seen from the cross section of a spacer device according to FIG. 1 that the holder 1 of a spacer device 2 is U-shaped and is composed of two legs 3 and a web 4. Support feet 5 are attached to the free ends of the legs 3 and are made, for example, of plastic or concrete. The support feet 5 are only attached to the legs when the spacing device is supported on a formwork.

Der Steg 4 des Halters 1 ist dachförmig ausgebildet und weist eine ebene Scheitelpartie 6 auf, an welche gegen die Schenkel 3 geneigte Seitenstege 7 anschliessen.The web 4 of the holder 1 is roof-shaped and has a flat apex part 6 to which side webs 7 inclined against the legs 3 are connected.

Auf dem Steg 4 sind drei Längsträger 8, 9 angeordnet, wobei ein Zentrallängsträger 8 in der Mitte der Scheitelpartie 6 und je ein Seitenlängsträger 9 auf den Seitenstegen 7 im Uebergangsbereich 10 zu den Schenkeln 3 befestigt sind.On the web 4, three longitudinal members 8, 9 are arranged, a central longitudinal member 8 in the middle of the apex part 6 and one side longitudinal member 9 each being fastened to the side webs 7 in the transition region 10 to the legs 3.

Aus Fig. 1 ist ersichtlich, dass die Seitenstege 7 deutlich tiefer unter dem Zentrallängsträger 8 liegen, d.h. gegen die Schenkel 3 hin angeordnet sind. Es ist deshalb erforderlich, dass die Neigung der Seitenstege 7 bezüglich der Richtung des Zentrallängsträgers 8 genügend gross, d.h. im Bereich von etwa 40°, ausgebildet ist. Dadurch wird erreicht, dass das Widerstandmoment der Distanzhaltevorrichtung um eine Querachse so gross gehalten werden kann, dass die Distanzhaltevorrichtung so weitgehend stabil ist, dass sie auch durch eine Person begehbar ist. Hierbei ist zu beachten, dass zur Erreichung dieser Stabilität keineswegs Längsträger 8, 9 mit besonders grossem Querschnitt gewählt werden müssen. Vielmehr ist es möglich, den Querschnitt der Seitenlängsträger 9 kleiner zu halten als denjenigen des Zentrallängsträgers 8. Bei Verwendung von Rundstäben als Längsträger 8, 9 kann beispielsweise der Durchmesser der Seitenlängsträger 9 etwa 3 mm und derjenige des Zentrallängsträgers 8 beispielsweise 5 oder 6 mm betragen. Es wird dadurch eine ausgesprochene Leichtbau-Distanzhaltevorrichtung geschaffen, die einerseits eine verhältnismässig grosse Stabilität aufweist und andererseits wegen des verhältnismässig geringen Materialanteils kostengünstig ist.From Fig. 1 it can be seen that the side webs 7 are significantly lower below the central longitudinal beam 8, i.e. are arranged against the legs 3. It is therefore necessary that the inclination of the side webs 7 with respect to the direction of the central side member 8 is sufficiently large, i.e. is formed in the range of about 40 °. It is thereby achieved that the section modulus of the spacer device about a transverse axis can be kept so large that the spacer device is so largely stable that it can also be walked on by a person. It should be noted here that in order to achieve this stability, longitudinal members 8, 9 with a particularly large cross-section do not have to be selected. Rather, it is possible to keep the cross section of the side members 9 smaller than that of the central side member 8. When using round bars as the side members 8, 9, for example, the diameter of the side members 9 may be about 3 mm and that of the central member 8 may be 5 or 6 mm, for example. This creates a pronounced lightweight spacer device, which on the one hand has a relatively high stability and on the other hand is inexpensive due to the relatively small amount of material.

In Fig. 2 ist eine solche Distanzhaltevorrichtung 2 dargestellt. Die Länge derselben kann verschieden sein und wird dem jeweiligen Bedarfsfall angepasst. Die in Fig. 2 dargestellten vier Halter weisen nicht die dachförmige Ausbildung des Halters 1 nach Fig. 1 auf, sondern der Steg 4 der Halter 1 weist eine Wölbung auf, durch welche die gleiche Anordnung der Längsträger 8, 9 erreicht werden kann wie bei der dachförmigen Ausbildung des Steges 4 gemäss Fig. 1. Die Halter 1 der Distanzhaltevorrichtung nach Fig. 2 sind ebenfalls mit Stützfüssen 5 versehen, jedoch ist dies, wie vorstehend erwähnt wurde, nicht in allen Anwendungsfällen erforderlich. Durch die gewölbte Ausbildung des Steges 4 der Halter 1 kann dieselbe unterschiedliche Höhenlage der Seitenlängsträger 9 zum Zentrallängsträger 8 erreicht werden.Such a spacing device 2 is shown in FIG. 2. The length of these can be different and is adapted to the respective need. The four holders shown in Fig. 2 do not have the roof-shaped design of the holder 1 according to Fig. 1, but the web 4 of the holder 1 has a curvature through which the same arrangement of the longitudinal beams 8, 9 can be achieved as in the roof-shaped design of the web 4 according to FIG. 1. The holder 1 of the spacer device according to FIG. 2 are also provided with support feet 5, but, as mentioned above, this is not necessary in all applications. Due to the curved design of the web 4 of the holder 1, the same different height position of the side longitudinal members 9 to the central longitudinal member 8 can be achieved.

Aus Fig. 3 ist ersichtlich, dass bei Verwendung von Haltern 1 gemäss Fig. 1 zur Bildung von Distanzhaltevorrichtungen 2 eine platzsparende Stapelung der Distanzhaltevorrichtungen möglich ist, wodurch ein entsprechend geringer Platzbedarf erforderlich ist. Der Platz zwischen zwei aufeinandergestapelten Distanzhaltevorrichtungen 2 beträgt nur etwa die Stärke des Zentrallängsträgers 8, da durch die Seitenlängsträger 9 mit kleinerer Stärke kein zusätzlicher Platz erforderlich ist.It can be seen from FIG. 3 that when using holders 1 according to FIG. 1 to form spacer devices 2, space-saving stacking of the spacer devices is possible, as a result of which a correspondingly small space requirement is required. The space between two stacked spacers 2 is only approximately the thickness of the central side member 8, since no additional space is required due to the side members 9 of smaller thickness.

Aus Fig. 3 kann zudem abgeleitet werden, dass diese günstigen Verhältnisse nicht nur durch die dachförmige Ausbildung des Steges 4 gemäss Fig. 1 erreicht werden kann, sondern auch bei Ausbildung des Steges 4 mit einer nach aussen gerichteten konvexen Wölbung.It can also be deduced from FIG. 3 that these favorable conditions can be achieved not only by the roof-shaped configuration of the web 4 according to FIG. 1, but also when the web 4 is designed with an outwardly convex curvature.

Als Material für die Halter 1 und die Längsträger 8, 9 kann ein kaltverfestigter Stahl verwendet werden. Jedoch ist es auch möglich, hierfür einen thermisch behandelten Stahl, z.B. einen aus der Walzhitze vergüteten Stahl, zu verwenden, welcher eine höhere Streckgrenze bei guten Zähigkeits- und Schweisseigenschaften aufweist.A strain-hardened steel can be used as the material for the holder 1 and the longitudinal beams 8, 9. However, it is also possible to use a thermally treated steel, e.g. to use a steel tempered from the rolling heat, which has a higher yield strength with good toughness and welding properties.

Bei der beschriebenen Distanzhaltevorrichtung können in den Längsträgern 8, 9 Einbuchtungen gemäss der eingangs beschriebenen Ausführung (EP-A-0 176 815) vorgesehen werden, ohne dass dadurch die Stabilität der Distanzhaltevorrichtung ungünstig beeinflusst würde.In the case of the spacer device described, indentations according to the embodiment described at the beginning (EP-A-0 176 815) can be provided in the longitudinal beams 8, 9, without the stability of the spacer device being adversely affected thereby.
