Description

Die Erfindung betrifft ein Element zur Erstellung einer Dehn-bzw. Trennfuge in einer Bodendeckenplatte. Dehnfugen in Bodendeckenplatten ermöglichen Bewegungen infolge Temperaturänderungen sowie in Folge Schwindens, ohne dass Risse und sonstige Schäden eintreten. Der Abstand der Dehnfugen hängt von den jeweils verwendeten Baustoffen und den möglichen Temperaturdifferenzen ab. Im Hochbau ordnet man Fugen üblicherweise bei Bauwerklängen über 25m an. Am fertigen Bauwerk werden die Dehnfugen mittels Fugenbänder verschlossen.The invention relates to an element for creating an expansion or. Parting line in a floor slab. Expansion joints in floor slabs allow movements due to changes in temperature and shrinkage without cracks and other damage. The distance between the expansion joints depends on the building materials used and the possible temperature differences. In building construction, joints are usually arranged for building lengths over 25m. On the finished building, the expansion joints are closed using joint tapes.

Bei der Erstellung einer Bodendeckenplatte wird die Armierung in die Verschalung angebracht und im Bereiche einer Dehnfuge unterbrochen. Die Dehnfuge selber wird durch ein in die Verschalung befestigtes Schalungsbrett, welches beidseitig mit Trennmitteln versehen ist, gebildet. Nach der Aushärtung des Betons wird dieses Brett entfernt. In neuerer Zeit wird statt des Schalungsbrettes zugeschnittenes Plattenmaterial verwendet, welches in der Fuge verbleibt.When creating a floor slab, the reinforcement is placed in the formwork and interrupted in the area of an expansion joint. The expansion joint itself is formed by a formwork board attached to the formwork, which is provided with release agents on both sides. After the concrete has hardened, this board is removed. In recent times, cut sheet material that remains in the joint has been used instead of the formwork board.

Oft wird auch eine Bodendeckenplatte aus Schall- oder Wärmeisolationsgründen unterteilt. Hierbei ist es jedoch oft erwünscht, dass die Querkräfte von einem Bodendeckenteil zum Anderen übertragen werden können. Dies bedeutet, dass die Kräfte der Armierungen über die Trennfuge hinweg weitergeleitet werden sollen. Trennfugen der -letztgenannten Art werden meist durch Einlegen von Isolationsmaterial in Plattenform erstellt.Often a floor slab is divided for sound or heat insulation reasons. However, it is often desirable here that the transverse forces can be transferred from one floor cover part to the other. This means that the forces of the reinforcements should be transmitted across the joint. Joints of the latter type are usually created by inserting insulation material in plate form.

Die Armierung von Bodendeckenplatten wird meist in Akkord erstellt. Dabei wirkt sich die Anbringung einer Dehn-oder Trennfuge meist hinderlich und zeitraubend aus. Entsprechend lassen Qualität und Exaktheit der Dehn- und Trennfugen viel zu wünschen übrig.The reinforcement of floor slabs is usually created in chords. The installation of an expansion or parting line is usually a hindrance and time-consuming. Accordingly, the quality and accuracy of the stretch and Parting lines left much to be desired.

Die vorliegende Erfindung stellt sich zur Aufgabe ein Element zur Erstellung einer Trennfuge in einer Bodendeckenplatte zu schaffen, welches die vorgenannten Nachteile behebt und die Anbringung der Armierung erleichtert.The present invention has for its object to provide an element for creating a parting line in a floor slab, which eliminates the aforementioned disadvantages and facilitates the attachment of the reinforcement.

Diese Aufgabe löst ein Element gemäss Oberbegriff des Patentanspruches welches sich dadurch auszeichnet, dass mindestens zwei rechtwinklig gebogene Eisen mit je einem langen und einem kurzen Schenkel, vorhanden sind wobei die langen und die kurzen Schenkel je für sich mittels Armierungseisen untereinander verbunden sind und die Platte distanziert, parallel.zur Ebene in der die kurzen Schenkel liegen an denselben befestigt ist.This object is achieved by an element according to the preamble of the patent claim, which is characterized in that there are at least two brackets bent at right angles, each with a long and a short leg, the long and the short legs being connected to one another by means of reinforcing irons and spacing the plate apart , parallel. to the plane in which the short legs lie attached to the same.

In der Zeichnung sind zwei Ausführungsbeispiele des Erfindungsgegenstandes dargestellt und anhand der nachfolgenden Beschreibung erläutert.In the drawing, two exemplary embodiments of the subject matter of the invention are shown and explained with the aid of the following description.

Es zeigt:

  • Figur 1 ein Element zur Erstellung einer Trennfuge und
  • Figur 2 ein Element zur Erstellung einer Dehnfuge in einer Bodendeckenplatte.
It shows:
  • Figure 1 shows an element for creating a parting line and
  • Figure 2 shows an element for creating an expansion joint in a floor slab.

Mit gross E ist die Ebene der nicht dargestellten Verschalung bezeichnet. Das Element zur Erstellung einer Trennfuge besteht aus drei rechtwinklig gebogenen Eisen 1, die mittels Nägel 2 auf der Verschalung befestigt sind. Hülsen 3 durch den die Nägel 2 hindurchgeführt sind distanzieren die Eisen 1 -von der Verschalung. Die langen Schenkel 10 der rechtwinklig gebogenen Eisen 1 sind durch ein Armierungseisen 11 als Verstrebungen untereinander verbunden. An den kurzen Schenkeln 12 der Eisen 1 sind zwei parallel verlaufende Armierungseisen 13 angeschweisst. Parallel zur Ebene, gebildet aus den Armierungseisen 13 und den kurzen Schenkeln 12, ist eine Platte 4 aus Isolationsmaterial distanziert gehalten. Die Halterung erfolgt durch Dämmstifte 5 die die Platte 4 durchsetzen und formschlüssig in den kurzen Schenkeln 12 gehalten sind. Auf den als Armierungseisen ausgebildeten Verstrebungen 13 sind Distanzierungselemente 6 aufgeklemmt, die mit ihrer Auflagefläche an der Platte 4 anliegen. In regelmässigen Abständen ist die Isolationsplatte 4 von Querkraftdorne 7 durchsetzt. Die Querkraftdorne 7, in der Form von runden Eisenstäben, sind an den Armierungseisen 13, die die kurzen Schenkel 12 der rechtwinklig gebogenen Eisen 1 verbinden angeschweisst. Zur Verstärkung sind die Querkraftdornen 7 auf der gegenüberliegenden Seite der Platte nochmals mit einem Armierungseisen 8 zur Verstrebung verschweisst.The level of the casing, not shown, is denoted by large E. The element for creating a parting line consists of three right-angled irons 1, which are fastened to the formwork by means of nails 2. Sleeves 3 through which the nails 2 are guided distance the iron 1 from the casing. The long legs 10 of the iron 1 bent at right angles are connected to one another by bracing 11 as struts. Two parallel reinforcing bars 13 are welded to the short legs 12 of the bars 1. Parallel to the plane, formed from the reinforcing bars 13 and the short legs 12, a plate 4 made of insulating material is held at a distance. The holder is carried out by insulation pins 5 which penetrate the plate 4 and are held in a form-fitting manner in the short legs 12. Spacers 6 are provided on the struts 13 designed as reinforcing bars clamped, which rest with their bearing surface on the plate 4. The insulation plate 4 is penetrated by shear force mandrels 7 at regular intervals. The transverse force mandrels 7, in the form of round iron bars, are welded to the reinforcing irons 13, which connect the short legs 12 of the iron 1 bent at right angles. For reinforcement, the transverse force mandrels 7 are welded again on the opposite side of the plate with a reinforcing iron 8 for bracing.

Das in der Figur 1 dargestellte Trennfugenelement dient wie sein Name aussagt zur Erstellung einer Trennfuge. Die beidseitig der Isolationsplatte 4 verlaufende Bodendeckenplatte verläuft kräftemässig durch das Element hindurch. Die Querkraftdorne 7 dienen diesem Kräfteverlauf. Wärme- und schalltechnisch wirkt die Trennfuge als einwandfreie Schranke. Armierung, Trennfuge und Isolierung werden mit diesem Element in einem Arbeitsgang erstellt.The parting line element shown in FIG. 1 serves, as its name suggests, to create a parting line. The floor cover plate running on both sides of the insulation plate 4 runs forcefully through the element. The transverse force mandrels 7 serve this course of forces. In terms of heat and sound, the parting line acts as a flawless barrier. Reinforcement, parting line and insulation are created with this element in one step.

In der Figur 2 ist ein Element zur Erstellung einer Dehnfuge in einer Bodendeckenplatte dargestellt. Auch hier sind die rechtwinklig gebogenen Eisen 1 -an ihren langen Schenkeln 10 mittels einem Armierungseisen 11 untereinander verbunden. Ebenso sind die kurzen Schenkel 12 mittels einer Verstrebung 13 aus einem Armierungseisen miteinander verschweisst. Die Stifte 5 durchsetzen die relativ dünne Platte 41 und halten diese an den kurzen Schenkeln 12 der gebogenen Eisen 1 fest. Distanzelemente 9 in Form von Kunststoffrohrabschnitten sorgen für eine vorgegebene Distanz zwischen der Platte 4' und den kurzen Schenkeln 12. Zur Vergrösserung der Auflagefläche der relativ dünnen Platte 4' ist diese an ihrer unteren Längskante mit einer Längsnut versehen in die eine aufsteckbare Dreikantleiste 14 gehalten ist. Auch die Platte 4', die zur Erstellung der Dehnfuge dient und in derselben nach Fertigstellung der Bodendeckenplatte verbleibt, wird von Querkraftdornen 7 durchsetzt. Auf der Seite der rechtwinklig gebogenen Eisen 1 sind die Querkraftdorne 7 mit der Armierung verbunden, indem sie an der Verstrebung 13 angeschweisst sind. Selbstverständlich werden die Elemente mit der Armierung der Bodendeckenplatte verbunden. An der den rechtwinkligen Eisen 1 gegenüberliegenden Seite der Platte 4- sind die Querkraftdorne 7 von einer einseitig geschlossenen Hülse 15 umgeben. Die Hülse 15 ist mit einer rechteckigen Flansch versehen zur Befestigung an der Platte 4'. Die Querkraftdorne 7 können somit die Dehnbewegungen mitvollziehen, indem sie mit der Hülse 15 sich entsprechend verschieben können. Die Querkraftdorne 7 können so ein Biegemoment, welches auf die Bodendeckenplatte im Bereiche der Dehnfuge auftritt, von einem Bodendeckenteil auf das andere über die Dehnfuge hinweg übertragen.FIG. 2 shows an element for creating an expansion joint in a floor slab. Here, too, are the right-angled irons 1 - on theirs long legs 10 connected to each other by means of a reinforcing iron 11. Likewise, the short legs 12 are welded to one another by means of a bracing 13 made of a reinforcing iron. The pins 5 pass through the relatively thin plate 4 1 and hold it on the short legs 12 of the bent iron 1. Spacers 9 in the form of plastic pipe sections ensure a predetermined distance between the plate 4 'and the short legs 12. To enlarge the contact surface of the relatively thin plate 4', this is provided on its lower longitudinal edge with a longitudinal groove in which a triangular bar 14 can be attached . The plate 4 ', which is used to create the expansion joint and remains in it after completion of the floor slab, is penetrated by transverse force mandrels 7. On the side of the iron 1 bent at right angles, the transverse force mandrels 7 are connected to the reinforcement by being welded to the strut 13. Of course, the elements are connected to the reinforcement of the floor slab. On the side of the plate 4 opposite the rectangular iron 1, the transverse force mandrels 7 are surrounded by a sleeve 15 which is closed on one side. The sleeve 15 is with a rectangular flange provided for attachment to the plate 4 '. The transverse force mandrels 7 can thus follow the expansion movements by being able to move accordingly with the sleeve 15. The transverse force mandrels 7 can thus transmit a bending moment which occurs on the floor cover plate in the area of the expansion joint from one floor cover part to the other over the expansion joint.

Ueber die zu verwendenden Materialien der Einzelteile des erfindungsgemässen Elementes brauchen keine Angaben gemacht zu werden, da diese den herkömmlichen, auf den Bau zu verwendenden Materialien entspricht.No information needs to be given about the materials to be used for the individual parts of the element according to the invention, since these correspond to the conventional materials to be used in construction.
