Abstract

The spacer assembly (1) is used with a hollow concrete structural element in a building. It incorporates an elongated distance piece (2) consisting of two elongated plates (12,14) braced together by triangular bracing fillets (15) positioned at intervals along their length. The tip (3) of the assembly is pointed. The bottom end has four comparatively widely spaced feet (4-7) which allow the assembly to stand upright on a level surface. There are grooves (8,9) in the feet which are open at the top and can accommodate reinforcing rods (10,11).

Description

Die Erfindung bezieht sich auf einen Distanzhalter gemäß dem Oberbegriff des Hauptanspruches.The invention relates to a spacer according to the Preamble of the main claim.

Bei der Herstellung von Betonhohlraumelementen werden die Bewehrungen auf einer Formplatte ausgelegt, wobei die in einer Ebene parallel zur Formplatte befindlichen Bewehrungen aus Tragbewehrung und Verteilerbewehrung besteht. An diese Bewehrungselemente werden Distanzhalter angeschlossen, die der Höhe der maximalen Stärke des herzustellenden Betonhohlraumelementes entsprechen, und um eine korrekte Lage dieser Distanzhalter zu sichern, werden diese in die Tragbewehrung oder Verteilerbewehrung eingeklinkt. Dieses Einklinken erfolgt von Hand, und hierbei ist nicht sichergestellt, daß die Distanzhalter auch genau lotrecht zur Formplatte ausgerichtet sind.In the production of concrete cavity elements, the Reinforcements laid out on a form plate, the in reinforcements located parallel to the form plate consists of supporting reinforcement and distribution reinforcement. To this Reinforcement elements are connected to the spacers the height of the maximum thickness of the concrete cavity element to be produced correspond, and to a correct location of this To secure spacers, these are in the supporting reinforcement or distribution reinforcement latched. This latching takes place by hand, and this does not ensure that the spacers are also aligned exactly perpendicular to the mold plate.

Der Erfindung liegt die Aufgabe zugrunde, einen Distanzhalter zu schaffen, der so in die Bewehrung eingeklinkt werden kann, daß seine korrekte lotrechte Lage gesichert ist, ohne daß zusätzliche Hilfsmittel notwendig sind und trotzdem das Einklinken schnell von Hand durchgeführt werden kann.The invention has for its object a spacer to create that can be latched into the reinforcement that its correct vertical position is secured without additional Tools are necessary and still latching can be done quickly by hand.

Diese der Erfindung zugrundeliegende Aufgabe wird durch die Lehre des Hauptanspruches gelöst. This object of the invention is achieved by Teaching of the main claim solved.

Vorteilhafte Ausgestaltungen sind in den Unteransprüchen erläutert.Advantageous configurations are explained in the subclaims.

Mit anderen Worten ausgedrückt wird vorgeschlagen, daß der eigentliche Distanzhalter an seinem unteren Ende mit Stützelementen ausgerüstet ist, und zwar vorzugsweise vier Stützelementen, so daß ein sicheres Aufstehen in lotrechter Stellung gewährleistet ist. In diese Stützelemente sind Aufnahmenuten eingebracht, wovon die eine Aufnahmenut der Höhe der Unterkante der Tragbewehrung entspricht und die andere Aufnahmenut eine Tiefe aufweist, die der Höhe der Unterkante der Verteilerbewehrung entspricht, wobei vorzugsweise diese beiden Aufnahmenuten in den Stützelementen um 90° versetzt angeordnet sind. Hierbei sind vorzugsweise die Stützelemente als Flächenelemente ausgebildet, so daß eine leichte Einarbeitung dieser Aufnahmenuten möglich ist.In other words, it is suggested that the actual spacer at its lower end with support elements is equipped, preferably four support elements, so that you can get up safely in a vertical position is guaranteed. There are grooves in these support elements introduced, of which the one receiving groove the height of the lower edge corresponds to the supporting reinforcement and the other receiving groove has a depth which is the height of the lower edge of the Distribution reinforcement corresponds, preferably these two Receiving grooves in the support elements are arranged offset by 90 ° are. Here, the support elements are preferably as Surface elements designed so that easy incorporation of these grooves is possible.

Hieraus ist erkennbar, daß es nunmehr möglich ist, den eigentlichen Distanzstab durch eine einfache Einhängbewegung hinter die Tragbewehrung und die Verteilerbewehrung anzuschließen, wobei normalerweise die eine Aufnahmenut hinter die Verteilerbewehrung greift und die andere Aufnahmenut hinter die Tragbewehrung. Sollte durch Nachlässigkeit beim Anhängen des Distanzstabes die Nuten für die Bewehrungen verwechselt werden, so ist dies auch nicht schlimm und trotzdem wird der Distanzstab sicher in den beiden sich kreuzenden Bewehrungen gehalten und durch seine Vierpunktaufstellung auf der eigentlichen Formplatte sicher nach oben ausgerichtet.From this it can be seen that it is now possible to do the actual Spacer bar by a simple hanging movement behind to connect the load-bearing reinforcement and the distribution reinforcement, usually the one receiving groove behind the distributor reinforcement grips and the other receiving groove behind the supporting reinforcement. Should negligence when attaching the Spacer bar confused the grooves for the reinforcements not so bad, and yet the Spacer bar securely in the two crossing reinforcements held and due to its four-point arrangement on the actual Form plate securely aligned upwards.

Der Distanzstab ist dabei vorzugsweise aus zwei sich kreuzenden lotrechten Scheiben hergestellt, die durch absatzweise über die Höhe verteilt angeordnete Winkelplatten stabilisiert werden. Das obere Ende des Distanzstabes ist punktförmig gestaltet.The spacer rod is preferably made of two intersecting vertical discs made by paragraphs over the height of the distributed angle plates can be stabilized. The upper end of the spacer rod is designed in a punctiform manner.

Nachdem die Distanzstäbe an den Bewehrungen verankert sind, kann die eine Betonschicht gegossen werden, wodurch die Distanzstäbe sicher in diesem Beton verankert sind und senkrecht gegenüber der Ebene des Betons nach oben vorstehen. Nach Aushärten des Betons kann nunmehr dieses Bauteil in die noch flüssige andere Betonschicht in an sich bekannter Weise eingepreßt werden und nunmehr garantieren die Distanzstäbe die korrekte Abstandshalterung zwischen den beiden Außenflächen der das Hohlraumelement bildenden Betonschichten.After the spacer bars are anchored to the reinforcements, a layer of concrete can be poured, making the Spacer bars are securely anchored in this concrete and vertical protrude upwards from the level of the concrete. After the concrete has hardened, this component can now be placed in the still liquid other concrete layer in a manner known per se are pressed in and now guarantee the spacer bars the correct spacing between the two outer surfaces of the concrete layers forming the cavity element.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung erläutert.An embodiment of the invention is described below the drawing explained.

In der Zeichnung ist schaubildlich ein Distanzhalter 1 dargestellt, der aus einem Stab 2 besteht, der wiederum selbst vorzugsweise aus zwei plattenförmigen Elementen 12 und 14 gebildet ist, die senkrecht aufeinanderstehen und sich durchsetzen. Zur Stabilisierung der Scheiben 12 und 14 sind Winkelplatten 15 vorgesehen, die im Abstand voneinander übereinander angeordnet sind. An seinem unteren Ende ist der Stab 2 mit vier Stützelementen ausgerüstet, die die Bezugszeichen 4, 5, 6 und 7 tragen und als Flächenelemente ausgebildet sind, so daß dadurch ein gutes Aufstehen des Stabes 2 gewährleistet ist. In dem Flächenelement 5 ist bei dem dargestellten Ausführungsbeispiel eine Aufnahmenut 8 vorgesehen, die zur Aufnahme der Verteilerbewehrung 11 dient, so daß die Unterkante oder das Nuttiefste der Nut 8 der üblicherweise vorgesehenen Höhe der Verteilerbewehrung 11 entspricht.A spacer 1 is shown in the drawing, which consists of a rod 2, which in turn preferably itself formed from two plate-shaped elements 12 and 14 that are perpendicular to each other and prevail. Angle plates are used to stabilize the disks 12 and 14 15 provided, one above the other at a distance are arranged. At its lower end, the rod 2 is with four support elements equipped with the reference numerals 4, 5, 6 and 7 and are designed as surface elements, so that a good stand up of the rod 2 is guaranteed. In the surface element 5 is in the illustrated embodiment a receiving groove 8 is provided for receiving the Distribution reinforcement 11 is used so that the lower edge or Groove depth of the groove 8 of the usually provided height of the Distribution reinforcement 11 corresponds.

In dem Flächenelement 6 ist eine Nut 9 vorgesehen, die zur Aufnahme der Tragbewehrung dient, so daß das Nuttiefste der Nut 9 der Unterkante der Tragbewehrung 10 angepaßt ist. Die beiden Bewehrungen kreuzen sich rechtwinklig und liegen durch die bestimmte Gestaltung der Nuten 8 und 9 übereinander.In the surface element 6, a groove 9 is provided, which for Includes the supporting reinforcement, so that the deepest part of the Groove 9 of the lower edge of the supporting reinforcement 10 is adapted. The both reinforcements cross at right angles and lie through the specific design of the grooves 8 and 9 one above the other.

Der eigentliche Stab kann im Spritzguß hergestellt werden und läuft an seinem oberen Ende punktförmig zu, so daß dadurch der Abstand des herzustellenden Hohlraumelementes dadurch bestimmt wird, daß diese punktförmige Zuspitzung 3 an die den Stützflächen 4 bis 7 gegenüberliegende Formwand angedrückt wird.The actual rod can be injection molded and runs in a punctiform manner at its upper end, so that the distance of the cavity element to be produced thereby it is determined that this point taper 3 to the Support surfaces 4 to 7 opposing mold wall pressed becomes.
