Abstract

The spacer possesses carrying legs (1) which are arranged in a first plane and supporting legs (3) which are arranged in another plane, the two planes forming an acute angle. At the junction of the two legs, a web (5) is fastened in order to carry the upper reinforcement mat. Carrying limbs (6) with hooks (7) are arranged in the plane of the supporting legs (3) in order to receive the lower reinforcement mat. In order to increase the stability of the holder when loaded by the lower mat, the supporting legs (3) are bent inwards at the bottom, the bends (10) lying somewhat above the apex (8) of the hooks (7), as a result of which the resulting force acts on the carrying legs (1) in the direction of the bearing surface. To increase the carrying capacity of the hooks (7), the supporting legs (3) and the carrying limbs (6) are connected to one another by a strut (9). Such a spacer exhibits, with the same wire thickness, improved stability and a higher carrying capacity than previously known holders, and additionally facilitates the laying of the upper reinforcement mats. <IMAGE>

Description

Die vorliegende Erfindung bezieht sich auf einen Ab­standhalter für untere, bzw. äussere und obere, bzw. innere Bewehrungsmatten in Betondecken, bzw. Wänden, mit mehreren im wesentlichen in einer Ebene angeordneten Tragbeinen und mit der gleichen Anzahl im wesentlichen in einer die erste Ebene schneidenden zweiten Ebene angeordneten Stützbeinen sowie einem auf den Trag- und Stützbeinen befestigten Steg zum Tragen der oberen, bzw. inneren Bewehrungsmatte und mit in der Ebene der Stützbeine angeordneten Tragschenkeln mit fusseitigen Haken für die Aufnahme der unteren, bzw. äusseren Bewehrungsmatte wobei die Tragbeine etwa senkrecht auf die durch die Fussenden der Trag- und Stützbeine defi­nierten Ebene stehen.The present invention relates to a spacer for lower, or outer and upper, or inner reinforcement mats in concrete ceilings, or walls, with a plurality of support legs arranged essentially in one plane and with the same number essentially in one intersecting the first plane second level arranged support legs and a web attached to the support and support legs for carrying the upper or inner reinforcement mat and with support legs arranged in the plane of the support legs with foot hooks for receiving the lower or outer reinforcement mat, the support legs being approximately vertical stand on the level defined by the foot ends of the support and support legs.

Ein solcher Abstandhalter ist aus der EP-B-0 036 125 bekannt. Bei diesem Abstandhalter sind die Tragbeine und die randständigen Trag- und Stützbeine mittels einer umlaufenden Strebe miteinander verbunden. Die Haken für die untere Bewehrungsmatte sind ausschliesslich an den Stützbeinen angeordnet, und die Scheitel der Haken liegen in der Draufsicht gesehen innerhalb der durch die Fussstücke festgelegten Standflächen.Such a spacer is known from EP-B-0 036 125. In this spacer, the supporting legs and the peripheral supporting and supporting legs are connected to one another by means of a circumferential strut. The hooks for the lower reinforcement mat are arranged exclusively on the support legs, and the apexes of the hooks, seen in plan view, lie within the standing areas defined by the foot pieces.

Dieser Abstandhalter brachte insofern eine Verbesserung gegenüber dem damals bekannten Stand der Technik, indem er es ermöglichte, von oben die untere Bewehrungsmatte mittels der Haken zu erfassen und durch Umkippen des Abstandhalters die Matte hochzuheben und in den Haken zu halten, selbst wenn die bedienende Person auf der Bewehrungsmatte steht, wodurch eine Arbeitsersparnis erzielt wird.This spacer brought an improvement over the prior art known at the time, in that it made it possible to grasp the lower reinforcement mat from above by means of the hooks and to lift the mat and hold it in the hook by tipping over the spacer, even when the operator is on the reinforcement mat stands, which saves work.

Es ist davon ausgehend Aufgabe der vorliegenden Erfin­dung, die Standfestigkeit und die Tragfähigkeit solcher Halter zu erhöhen, ohne die Dicke der Drähte für deren Herstellung zu erhöhen. Ausserdem soll in einer weiteren Aufgabe die Stapelbarkeit solcher Halter erhöht und in einer weiteren Aufgabe das Verlegen der oberen Beweh­rungsmatte erleichtert werden. Diese Aufgaben werden mit einem in den Patentansprüchen definierten Abstandhalter gelöst.It is based on the object of the present invention, the stability and the load capacity of such Increase holder without increasing the thickness of the wires for their manufacture. In addition, the stackability of such holders is to be increased in a further task and the laying of the upper reinforcement mat is to be facilitated in a further task. These tasks are solved with a spacer defined in the claims.

Die Erfindung wird im folgenden anhand einer Zeichnung eines Ausführungsbeispiels näher erläutert.

  • Fig. 1 zeigt in perspektivischer Sicht den erfindungs­gemässen Abstandhalter, und
  • Fig. 2 zeigt eine Ausschnittsvergrösserung von Figur 1.
The invention is explained below with reference to a drawing of an embodiment.
  • 1 shows a perspective view of the spacer according to the invention, and
  • 2 shows an enlarged detail of FIG. 1.

In der Zeichnung erkennt man die Tragbeine 1 mit ihren Füssen 2, in der Regel aus Kunststoff, die Stützbeine 3 mit den Füssen 4 und den an der Verbindungsstelle zwischen den Trag- und Stützbeinen befestigten Steg 5, auf dem die obere Bewehrungsmatte zu liegen kommt. Aus Figur 2 geht deutlich hervor, dass die etwa in einer Ebene angeordneten Tragbeine 1 senkrecht zur Ebene stehen, die durch die Fussenden gebildet wird. In vorliegendem Fall ist der Oeffnungswinkel zwischen den Trag- und Stützbeinen etwa 50°, doch ist es selbstver­ständlich, dass dieser Winkel von den Abmessungen des Halters abhängt, d.h. von den verschiedenen, in der Regel normierten Abständen zwischen den unteren und oberen Bewehrungsmatten und in einem Bereich von 40 - ­60° liegen kann.In the drawing you can see the support legs 1 with their feet 2, usually made of plastic, the support legs 3 with the feet 4 and the web 5 attached to the connection point between the support and support legs, on which the upper reinforcement mat comes to rest. It is clear from FIG. 2 that the support legs 1 arranged approximately in one plane are perpendicular to the plane which is formed by the foot ends. In the present case, the opening angle between the support and support legs is about 50 °, but it goes without saying that this angle depends on the dimensions of the holder, i.e. of the different, usually standardized distances between the lower and upper reinforcement meshes and in a range of 40 - 60 °.

In der gleichen Ebene wie die Stützbeine sind Trag­schenkel 6 angeordnet, die in je einen Haken 7 für die untere Bewehrungsmatte münden, wobei der Abstand zwischen dem Scheitel 8 des Hakens und dem Boden ebenfalls normiert ist und in vorliegendem Beispiel zwei oder drei Zentimeter beträgt. Auf der Seite der Tragbeine kann der Schenkel 12 entweder bis ganz auf den Boden gezogen sein und Füsse 13 aufweisen, wie in Figur 1 strichpunktiert am ersten Tragschenkel links angedeutet worden ist, oder sich nur ein kleines Stück längs der Tragbeinebene erstrecken. Die Stützbeine sowie die Tragschenkel sind durch eine Strebe 9 miteinander verbunden, wobei diese Verbindung zwischen den Stützbeinen und den Tragschen­keln vorallem den Tragschenkeln eine grosse Festigkeit verleiht.Support legs 6 are arranged in the same plane as the support legs, each of which opens into a hook 7 for the lower reinforcement mat, the distance between the apex 8 of the hook and the floor also being standardized and in the present example two or three Centimeters. On the side of the support legs, the leg 12 can either be pulled all the way to the ground and have feet 13, as has been indicated by dash-dotted lines on the first support leg on the left, or can only extend a small distance along the support leg plane. The support legs and the support legs are connected to one another by a strut 9, this connection between the support legs and the support legs providing the support legs with great strength.

Zwecks Erhöhung der Standfestigkeit, d.h. um einen grösstmöglichsten Schutz gegenüber Kippen des Abstand­halters zu gewährleisten, sind die Stützbeine in ihrem unteren Teil gegenüber der von den Stützbeinen gebilde­ten Ebene nach einwärts, d.h. in Richtung der Tragbeine geknickt, wobei die Knickstelle 10 etwas oberhalb des Scheitels 8 des Hakens 7 angeordnet ist. Aus Figur 2 insbesondere geht hervor, dass ein Druck auf den Haken, d.h. auf dessen Scheitel 8 und Knickstelle 10 bewirkt, dass der Abstandhalter in Richtung der Tragbeine an den Boden gepresst wird, so dass ein Umkippen dadurch nicht möglich ist. Die Längsachse des Fusses schliesst mit der Senkrechten S zur Ebene, die durch die Fussenden gebil­det wird, in vorliegendem Beispiel einen Winkelαvon ungefähr 30° ein, doch kann dieser Winkel zwischen 25 und 35° liegen.In order to increase the stability, i.e. In order to ensure the greatest possible protection against tilting of the spacer, the lower part of the support legs is inwards relative to the plane formed by the support legs, i.e. kinked in the direction of the supporting legs, the kink 10 being arranged somewhat above the apex 8 of the hook 7. From Figure 2 in particular it can be seen that pressure on the hook, i.e. on its apex 8 and kink 10 causes the spacer to be pressed against the floor in the direction of the support legs, so that tipping over is not possible. The longitudinal axis of the foot includes an angle α of approximately 30 ° with the perpendicular S to the plane which is formed by the foot ends, but this angle can be between 25 and 35 °.

Die Verbindungsstrebe 9 muss nicht derart nahe beim Scheitel respektive beim Haken liegen, sondern kann auch weiter oben, 9a, angeordnet sein, was insbesondere dann Vorteile bringt, falls Kabel, Rohre und dergleichen vor dem Stellen des Abstandhalters auf der unteren Beweh­rungsmatte angeordnet werden müssen. Dadurch, dass keine unteren Streben von den Trag- zu den Stützbeinen ange­ordnet sind, kann die Stapelbarkeit solcher Abstand­halter wesentlich erhöht werden. Ausserdem kann dadurch die Verwendung von Normgrössen in Rastern wesentlich besser durchgeführt werden und es kann sichergestellt werden, dass vor allem die unteren Bewehrungsmatten zwangsläufig in regelmässigen Abständen gehalten werden.The connecting strut 9 does not have to be so close to the apex or the hook, but can also be arranged further up, 9a, which is particularly advantageous if cables, pipes and the like have to be arranged on the lower reinforcement mat before the spacer is placed. Because no lower struts are arranged from the support legs to the support legs, the stackability of such spacers can be significantly increased. It can also the use of standard sizes in grids can be carried out much better and it can be ensured that, above all, the lower reinforcement mats are inevitably kept at regular intervals.

Aus Figur 1 geht hervor, dass der Steg 5 zuoberst angeordnet ist, und dass es keine Teile gibt, die über den Steg hinausragen. Im Gegenteil sind die Enden 11 des Steges leicht nach unten gebogen, um das Verlegen der oberen Matten zu erleichtern und zu verhindern, dass sie von diesen Stegenden aufgespiesst werden.It can be seen from FIG. 1 that the web 5 is arranged at the top and that there are no parts which protrude beyond the web. On the contrary, the ends 11 of the web are slightly bent downwards in order to facilitate the laying of the upper mats and to prevent them from being impaled by these web ends.

Die Fussenden der Tragschenkel 6 können zwecks Verbes­serung der Standfestigkeit ebenfalls in Richtung der Tragbeine 1 geknickt sein (Knickstelle 10a), wobei der Knickwinkel 35° bezogen auf oben definierte Senkrechte S und einem Betrag liegt, bei dem das Fussende in der Verlängerung des Tragschenkels liegt.The foot ends of the support legs 6 can also be bent in order to improve the stability in the direction of the support legs 1 (kink 10a), the kink angle being 35 ° with respect to the vertical S defined above and an amount at which the foot end lies in the extension of the support leg.

Bei grösseren, d.h. höheren Abstandhaltern können die Tragbeine leicht geöffnet werden, das heisst gegenüber der Senkrechten S eine Neigung von bis zu 8° im Sinne einer Vergrösserung des Oeffnungswinkels aufweisen.Larger, i.e. higher spacers, the support legs can be opened easily, that is, have an inclination of up to 8 ° with respect to the vertical S in the sense of an enlargement of the opening angle.

Beim Auslegen der Dimensionen des Rastermasses der Stütz- und Tragbeine und der Tragschenkel sowie deren Winkel muss Sorge getragen werden, dass diese Masse nicht mit denjenigen der Bewehrungsmatten zusammen­fallen, um ein ungehindertes Verlegen derselben zu gewährleisten, andererseits ein ungewolltes Verschieben seitwärts zu vermeiden. Selbstverständlich kann die Anzahl der Stütz- und Tragbeine und der Tragschenkel pro Längeneinheit je nach Verwendungszweck variieren.When designing the dimensions of the grid dimensions of the support and support legs and the support legs and their angles, care must be taken to ensure that these dimensions do not coincide with those of the reinforcement mats in order to ensure unimpeded laying of the same, and on the other hand to prevent undesired displacement sideways. Of course, the number of support and support legs and the support legs per unit length can vary depending on the intended use.

Das obige Beispiel wurde für horizontal verlegbare Bewehrungsmatten angegeben, doch kann es sich bei den Abstandhaltern auch um solche für Wandarmierungen handeln, wobei die Begriffe "unten" und "oben" durch "aussen" und "innen" zu ersetzen sind, sowie "Boden" durch "Auflagefläche".The above example was given for horizontal reinforcement mesh, but it can be the case with Spacers also act for wall reinforcements, whereby the terms "bottom" and "top" are to be replaced by "outside" and "inside", and "floor" by "contact surface".
