Description

Die Erfindung geht aus von einem Verbindungs- und Druckverteilungselement für zwei auf einer horizontalen Unterlage in der gleichen Ebene nacheinander zu betonierende Bauteile, die voneinander durch eine Dilatationsfuge zu trennen sind, mit einer Hülse und einem in die Hülse verschiebbar einsteckbaren Dorn, wobei sowohl um die Hülse als auch um den Dorn herum und im Abstand von denselben jeweils mindestens zwei in sich geschlossene, mit der Hülse bzw. dem Dorn fest verbundene Bügel aus Armierungsstäben angeordnet sind, welche Hülse zum Befestigen an einer Stirnschalung und zum Einlassen mit den Bügeln in dem zuerst zu betonierenden Bauteil und der Dorn zum Einstecken in die in dem ersten erhärteten Bauteil verankerte Hülse und zum Einlassen mit den Bügeln in den später zu betonierenden Bauteil bestimmt sind.The invention is based on a connection and pressure distribution element for two components to be concreted in succession on a horizontal base in the same plane, which are to be separated from one another by a dilatation joint, with a sleeve and a mandrel displaceably insertable into the sleeve, both about the Sleeve as well as around the mandrel and at a distance therefrom are each arranged at least two self-contained brackets made of reinforcing bars, which are firmly connected to the sleeve or the mandrel, which sleeve is to be fastened to a face formwork and to be inserted with the brackets in the first the component to be concreted and the mandrel are intended for insertion into the sleeve anchored in the first hardened component and for insertion with the brackets into the component to be concreted later.

Ein solches Verbindungs- und Druckverteilungselement ist in der europäischen Patentanmeldung Nr. 0119652 beschrieben. Bei dieser Lösung ist es von Nachteil, dass mit der Aenderung des Durchmessers des Dornes auch der Durchmesser der Hülse mit den aufgeschweissten Bügeln geändert werden muss, um das Einstecken des Dornes in die Oeffnung der entsprechenden Hülse zu ermöglichen. So müssen für verschiedene Zwecke sowohl die Dorne als auch die Hülsen von verschiedenen Durchmessern verwendet werden. Solche Verbindungs- und Druckverteilungselemente werden nämlich zur Verbindung von Bauteilen des Hoch- oder Tiefbaus, wie Dachplatten, Bodenplatten, Decken, Wände, Stützen, Stützmauern, oder Autobahnen oder Landungspisten der Flugplätze verwendet, welche Bauteile in einer genau gleichen Ebene zu fixieren sind. Die durch ein solches Element verbundenen Bauteile sind dem Einfluss unterschiedlicher Temepraturen und Drücken ausgesetzt, sodass sie in Richtung einer Fuge ausdehnen und zusammenziehen sollen.Such a connection and pressure distribution element is described in European Patent Application No. 0119652. With this solution, it is disadvantageous that, with the change in the diameter of the mandrel, the diameter of the sleeve with the welded-on brackets also has to be changed in order to enable the mandrel to be inserted into the opening of the corresponding sleeve. So both the mandrels and the sleeves of different diameters must be used for different purposes. Such connection and pressure distribution elements are namely used to connect building or civil engineering components, such as roof panels, floor panels, ceilings, walls, supports, retaining walls, or highways or landing strips of the airfields, which components are to be fixed in exactly the same plane. The components connected by such an element are exposed to the influence of different temperatures and pressures, so that they are in Expand and contract towards a joint.

Der im Patentanspruch 1 angegebenen Erfindung liegt die Aufgabe zugrunde, ein Verbindungs- und Druckverteilungselement zu schaffen, das es erlaubt, verschiedene Dorndurchmesser zu verwenden, ohne dass mit den Hülsen entsprechenden Durchmesser auch die Hülsenbügel ausgewechselt werden müssten. Dies erlaubt weiter, dass solche Bügel als Vorrat gehalten und nicht mit dem Wechsel der Hülse auf dieselbe aufgeschweisst werden müssen.The invention specified in claim 1 has for its object to provide a connection and pressure distribution element that allows different mandrel diameters to be used without the sleeve bracket having to be exchanged with the corresponding diameter sleeve. This further allows such brackets to be kept in stock and not to be welded onto the sleeve when the sleeve is changed.

Diese Aufgabe wird erfindungsgemäss bei dem Verbindungs- und Druckverteilungselement nach dem Oberbegriff des Patentanspruches 1 durch die Merkmale der Kennzeichnung des Patentanspruches 1 gelöst.This object is erbindungs- according to the invention in which V and dissolved pressure-distribution element according to the preamble of claim 1 by the features of the marking of claim 1.

Mit Vorteil sind die Stege mit dem Rohr einstückige Längsrippen, wobei jeder Stahlring einen Innendurchmesser hat, der dem Aussendurchmesser der Längsrippen entspricht.The webs with the tube are advantageously longitudinal ribs in one piece, each steel ring having an inside diameter which corresponds to the outside diameter of the longitudinal ribs.

The subject matter of the invention is explained in more detail below with reference to the drawing, for example. Show it:
  • 1 is a perspective view of a sleeve which is provided with two spirally formed brackets,
  • 2 is a perspective view of an assembly shoe for receiving one end of the sleeve according to FIG. 1,

Das in den Figuren dargestellte Element dient zur Verbindung von zwei auf der horizontalen Unterlage 1 in der gleichen Ebene nacheinander zu betonierenden Bauteilen 2, 3, die voneinander durch eine Dilatationsfuge 4 zu trennen sind, wie es insbesondere bei Autobahnen oder Flugplatzbahnen der Fall ist. Durch das in den Bauteilen eingelassene Element wird ein zwangsloses Ausdehen und Zusammenziehen der Bauteile ermöglicht, welche Bauteile unterschiedlichen Temperaturen ausgesetzt sind. Des weiteren dient das Element zur Verteilung der insbesondere beim Ausdehnen und Zusammenziehen der Bauteile auftretenden Kräfte über eine grössere Fläche im Beton.The element shown in the figures serves to connect two components 2, 3 to be concreted one after the other on the horizontal base 1 in the same plane, which are to be separated from one another by a dilatation joint 4, as is the case in particular in the case of motorways or airfield railways. The element embedded in the components enables the components to be expanded and contracted freely, which components are exposed to different temperatures. Furthermore, the element serves to distribute the forces that occur in particular when the components are expanded and contracted over a larger area in the concrete.

- Das Verbindungs- und Druckverteilungselement besteht aus einer Hülse 5, einem Montageschuh 16 und einem in die Oeffnung der Hülse 5 verschiebbar einsteckbaren Dorn 6. Die Hülse 5 umfasst ein Rohr 9 mit mindestens drei symmetrisch um das Rohr 9 herum und parallel zu seiner Längsachse x angeordneten Stegen 10 gleicher Höhe. Des weiteren umfasst die Hülse 5 mindestens zwei Stahlringe 11, welche auf die Stege 10 aufgepresst sind. Auf jedem Stahlring 11 ist von aussen ein Bügel 7 aufgeschweisst, der spiralförmig ausgebildet ist. Jeder Bügel 7 besteht aus Armierungsstäben, deren Dicke jedoch kleiner ist, als die Dicke der Stäbe der Grundarmierung 20 (Fig. 6). Am einen Ende 9a trägt das Rohr 9 einen senkrecht zur Längsachse x des Rohres 9 verlaufenden Flansch 12. Auf dem anderen Ende 9b trägt das Rohr 9 eine höhenverstellbare Abstützstange 13, die mittels einer Mutter 14 in der gewünschten Höhe fixierbar ist. Die Abstützstange 13 verläuft ebenfalls senkrecht zur Längsachse x des Rohres 9 in einer Bohrung einer Schraube 15, auf welcher die Fixiermutter 14 verschraubbar angeordnet ist.- The connection and pressure distribution element consists of a sleeve 5, an assembly shoe 16 and a plug 6 which can be slid into the opening of the sleeve 5. The sleeve 5 comprises a tube 9 with at least three symmetrically around the tube 9 and parallel to its longitudinal axis x arranged webs 10 of the same height. Furthermore, the sleeve 5 comprises at least two steel rings 11 which are pressed onto the webs 10. On each steel ring 11, a bracket 7 is welded from the outside, which is designed in a spiral shape. Each bracket 7 consists of reinforcing bars, the thickness of which, however, is smaller than the thickness of the bars of the basic reinforcement 20 (FIG. 6). At one end 9a, the tube 9 carries a flange 12 running perpendicular to the longitudinal axis x of the tube 9. At the other end 9b, the tube 9 carries a height-adjustable support rod 13 which can be fixed at the desired height by means of a nut 14. The support rod 13 also runs vertically right to the longitudinal axis x of the tube 9 in a bore of a screw 15 on which the fixing nut 14 is screwed.

Die Stege 10 sind mit dem Rohr 9 einstückige Längsrippen. Die mindestens zwei Stahlringe 11 haben den gleichen Innendurchmesser wie der Aussendurchmesser der Längsrippen. Aus diesem Grund müssen die Stahlringe 11 auf die Längsrippen mittels einer Presse oder durch Hammerschläge aufgepresst werden. Auf den Stahlringen 11 sind die Bügel 7 aufgeschweisst.The webs 10 are integral with the tube 9 longitudinal ribs. The at least two steel rings 11 have the same inside diameter as the outside diameter of the longitudinal ribs. For this reason, the steel rings 11 must be pressed onto the longitudinal ribs by means of a press or by hammer blows. The brackets 7 are welded onto the steel rings 11.

Wie aus den Figuren 3 und 4 ersichtlich ist, kann der Innendurchmesser des Rohres unterschiedlich sein, wobei die Höhe der Stege 10 ebenfalls variiert. Die Stahlringe 11, die alle den gleichen Innendurchmesser haben und auf welchen die Bügel 7 aufgeschweisst sind, können so auf Rohre von verschiedenen Innendurchmesser aufgepresst werden. So können die Stahlringe 11 mit den aufgeschweissten Bügeln 7 in grösseren Mengen als Vorrat gehalten werden. Die Rohre 9 von verschiedenen Innendurchmessern werden dann für Dorne 6 von verschiedenen Durchmessern verwendet.As can be seen from FIGS. 3 and 4, the inner diameter of the tube can be different, the height of the webs 10 also varying. The steel rings 11, which all have the same inner diameter and on which the brackets 7 are welded, can thus be pressed onto pipes of different inner diameters. The steel rings 11 with the welded-on brackets 7 can thus be kept in stock in larger quantities. The tubes 9 of different inner diameters are then used for mandrels 6 of different diameters.

Der in der Figur 2 dargestellte Montageschuh 16 weist eine U-förmige Aussparung 17 auf, die zur Aufnahme des einen Endes 9a des Rohres 9 bestimmt ist. Der Montageschuh 16 wird an die Stirnschalung 8 mittels Nägeln befestigt; zu diesem Zweck sind im Montageschuh 16 Nagellöcher 21 vorgesehen. Die der Stirnschalung 8 zuzuwendende Fläche des Montageschuhs 16 ist um die Aussparung 17 herum zur Aufnahme des Flansches 12 des Rohres 9 nach innen abgesetzt. Diese Einschubausnehmung ist mit 22 bezeichnet. Auf seiner der Stirnschalung abzuwendenden Fläche ist der Montageschuh 16 mit zwei Verankerungsrippen 18 versehen, deren jede auf der gegenüberliegenden Seite der Aussparung 17 liegt. Durch diese Verankerungsrippen wird eine gute Verankerung im Beton des ersten Bauteiles 2 erzielt. Die Seitenränder des Montageschuhes 16 weisen Zentrierschlitze 19 auf zum Erleichtern der Befestigung des Montageschuhs 16 an der Stirnschalung 8. Auf der der Stirnschalung 8 zuzuwendenden Fläche in Richtung der Aussparung 16 sind die Seitenränder des Montageschuhs 16 abgeschrägt. Dadurch wird eine gute Verankerung des Montageschuhs 16 nach dem Abreissen der Stirnschalung 8 von dem ersten erhärteten Bauteil 2 erreicht.The assembly shoe 16 shown in FIG. 2 has a U-shaped recess 17, which is intended to receive one end 9a of the tube 9. The assembly shoe 16 is fastened to the front formwork 8 by means of nails; for this purpose 16 nail holes 21 are provided in the assembly shoe. The face of the assembly shoe 16 facing the face formwork 8 is offset inwards around the recess 17 for receiving the flange 12 of the tube 9. This insertion recess is designated 22. On its surface facing away from the face formwork, the assembly shoe 16 is provided with two anchoring ribs 18, each of which lies on the opposite side of the recess 17. These anchoring ribs ensure good anchoring in the concrete of the first component 2. The side edges of the mounting shoe 16 have centering slits 19 to facilitate the attachment of the mounting shoe 16 to the front formwork 8. On the surface facing the front formwork 8 in the direction of the recess 16, the side edges of the mounting shoe 16 are chamfered. A good anchoring of the assembly shoe 16 is achieved after the end formwork 8 has been torn off from the first hardened component 2.

Die Abstützstange 13 besteht aus Stahl eines Durchmessers von etwa 5 mm. Sie ist durch eine Schraube 15 durchgeführt und in ihr in der Höhe verstellbar; sie dient als Abstützung des anderen Endes 9a des Rohres während des Einlassens der Hülse 5 in dem ersten Bauteil 2. Durch diese Abstützung werden die Drücke des eingegossenen Betons des ersten Bauteiles 2 aufgefangen, sodass dabei die Hülse 5 nicht aus ihrer Lage verschoben wird.The support rod 13 is made of steel with a diameter of approximately 5 mm. It is carried out by a screw 15 and adjustable in height; it serves as a support for the other end 9a of the tube during the insertion of the sleeve 5 into the first component 2. This support absorbs the pressures of the cast concrete of the first component 2, so that the sleeve 5 is not displaced from its position.

In der Figur 7 sind die zwei Bauteile 2, 3 mit den eingelassenen Hülse, Montageschuh und Dorn im Schnitt dargestellt. Die Stirnschalung wurde hier von dem ersten ausgehärteten Bauteil 2 abgerissen und der Dorn 6 in die Oeffnung der Hülse 5 eingeschoben. Nachträglich wurde der zweite Bauteil 3 betoniert und der Dorn 6 in demselben eingelassen. Es ist hier auch die Dilatationsfuge 4 zwischen den Bauteilen 2 und 3 sichtbar, die nach dem Entfernen der Stirnschalung 8 entstanden ist. Diese Dilatationsfuge ist mit Isolationsmaterial ausgefüllt. Nach dem Aushärten des zweiten Bau- teiles 3 ist die Verbindung hergestellt. Der Dorn 4 eines Durchmessers von 16 bis 40 mm der dem Durchmesser der Oeffnung der Hülse 5 passend entsprechen muss, ist in der Hülse verschiebbar eingesteckt.In Figure 7, the two components 2, 3 are shown with the recessed sleeve, mounting shoe and mandrel in section. The front formwork was torn off from the first hardened component 2 and the mandrel 6 was inserted into the opening of the sleeve 5. Subsequently, the second component 3 was concreted and the mandrel 6 embedded in the same. The dilatation joint 4 between the components 2 and 3 is also visible here, which was created after the front formwork 8 was removed. This dilatation joint is filled with insulation material. After hardening of the second B au- part 3 is made the connection. The mandrel 4 with a diameter of 16 to 40 mm, which must match the diameter of the opening of the sleeve 5, is slidably inserted in the sleeve.

Das oben beschriebene Verbindungs- und Druckverteilungselement wird komplett in einer Fabrik hergestellt. Auf der Baustelle wird es nur in Höhe eingestellt und zusammengelegt werden. Die Montage ist sehr einfach, weil nur der Montageschuh an der Stirnschalung in der gewünschten Höhe befestigt und die Hülse mit ihrem Flansch in die Einschubausnehmung des Montageschuhs eingeschoben. Das andere Ende der Hülse wird durch die Abstützstange in der gewünschten Höhe abgestützt. Die Hülse kann so während der Montage der schweren Grundarmierung nicht mehr nach unten geraten. Durch die Bügel wird eine bessere Verteilung des Druckes in den beiden Bauteilen erreicht.The connection and pressure distribution element described above is manufactured entirely in a factory. At the construction site, it will only be adjusted in height and folded. Installation is very simple because only the assembly shoe is attached to the forehead formwork at the desired height and the Inserted the sleeve with its flange into the slot in the assembly shoe. The other end of the sleeve is supported by the support rod at the desired height. This means that the sleeve can no longer fall down during assembly of the heavy basic reinforcement. The brackets achieve a better distribution of the pressure in the two components.
