Description

Die Erfindung betrifft ein Isolierelement aus Kunststoff zum thermischen Isolieren eines Bodens, welcher aus einer Mehrzahl in gegebenen Abständen voneinander angeordneter Balken aus Beton oder ähnlichem Material besteht, die an ihren Enden aufgelegt sind und an ihren unteren Kanten mit vorstehenden nasenförmigen Vorsprüngen versehen sind, welches Element einen plattenförmigen Teil aufweist, der mindestens an einer Seite einen mit diesem ein Ganzes bildenden vorstehenden Befestigungsteil aufweist, der im Bereich der unteren Kante einen in der Richtung des plattenförmigen Teiles vorstehenden nasenförmigen Vorsprung hat, welcher, wenn das Isolierelement in seiner Stellung angebracht ist, mit seiner unteren Kante auf dem vorstehenden nasenförmigen Vorsprung eines Balkens abgestützt ist, wobei der plattenförmige Teil unter diesem Balken liegt, und der Befestigungsteil im Zwischenraum zwischen zwei nebeneinander liegenden Balken angeordnet ist. Ein derartiges Isolierelement ist aus der niederländischen Patentanmeldung 8006629 bekannt.The invention relates to an insulating element made of plastic for thermally insulating a floor, which consists of a plurality of beams of concrete or similar material arranged at given distances from one another, which are placed at their ends and provided with projecting nose-shaped projections on their lower edges, which element has a plate-shaped part which has at least on one side a projecting fastening part which forms a whole with it, which in the region of the lower edge has a nose-shaped projection which projects in the direction of the plate-shaped part and which, when the insulating element is mounted in its position, also with its lower edge is supported on the protruding nose-shaped projection of a beam, the plate-shaped part lying under this beam, and the fastening part being arranged in the space between two adjacent beams. Such an insulating element is known from the Dutch patent application 8006629.

Bei dem bekannten Isolierelement ist der plattenförmige Teil nur an einer Seite mit einem Befestigungsteil versehen, welcher im Bereich der unteren Kante zwei in entgegengesetzten Richtungen vorstehende nasenförmige Teile hat, welche sich beim montierten Zustand des Elementes auf dem nasenförmigen Teil des Balkens, unter welchem sich der plattenförmige Teil befindet, bzw. dem nasenförmigen Teil des daneben befindlichen Balkens abstützen. Der plattenförmige Teil hat auf diese Weise ein freies Ende.In the known insulating element, the plate-shaped part is only provided on one side with a fastening part which has two nose-shaped parts projecting in opposite directions in the region of the lower edge, which, when the element is mounted, on the nose-shaped part of the beam, under which the plate-shaped part is located, or support the nose-shaped part of the adjacent beam. The plate-shaped part has a free end in this way.

Das bekannte Isolierelement wird erst angebracht, nachdem die Bodenbalken montiert sind, wobei der plattenförmige Teil des Elementes zwischen zwei nebeneinander angeordneter Balken eingesteckt wird, in welcher Stellung das freie Ende des plattenförmigen Teiles auf der unteren Kante des Verbindungsteiles des folgenden Isolierelementes anliegt. Das Anbringen der bekannten Isolierelemente ist eine zeitraubende Tätigkeit, die ausserdem an der Baustelle ausgeführt werden muss. Ausserdem ist es wichtig, dass das freie Ende des plattenförmigen Teiles jedes Isolierelementes gut auf der unteren Kante des Verbindungsteiles eines folgenden Isolierelementes anliegt, da sonst ein Teil der isolierenden Wirkung verloren wird. Um eine derartige gute Auflage zu erhalten, steht der plattenförmige Teil des bekannten Isolierelementes schräg gegenüber dem Befestigungsteil, wodurch in montierter Stellung, der plattenförmige Teil mit einer gewissen Vorspannung gegen die untere Kante des Verbindungsteiles des folgenden Isolierelementes abgestützt wird. Diese Ausbildung erhöht jedoch die Herstellungskosten der Isolierelemente und erschwert ihr Anbringen.The known insulating element is only attached after the floor beams have been installed, the plate-shaped part of the element being inserted between two adjacent beams, in which position the free end of the plate-shaped part rests on the lower edge of the connecting part of the following insulating element. Attaching the known insulating elements is a time-consuming activity that must also be carried out on the construction site. It is also important that the free end of the plate-shaped part of each insulating element lies well on the lower edge of the connecting part of a subsequent insulating element, since otherwise part of the insulating effect is lost. In order to obtain such a good circulation, the plate-shaped part of the known insulating element is inclined relative to the fastening part, so that in the assembled position, the plate-shaped part is supported with a certain preload against the lower edge of the connecting part of the following insulating element. However, this training increases the manufacturing costs of the insulating elements and complicates their attachment.

Aus DE-C-802091 ist einen Formstein für Decken mit eisernen Profilträgern bekannt, wobei bei der Herstellung der Decke die Formsteine zuerst auf den Fuss eines Trägers aufgeschoben werden, so dass der Fuss völlig ummantelt wird und darauf der Träger auf sein Auflager gelegt wird und weiter Deckensteine zwischen je zwei Trägern eingesetzt werden, welche so auf Abschrägungen den Formsteine aufgesetzt werden, dass die Unterseite der Decke völlig eben ist.From DE-C-802091 a shaped stone for ceilings with iron profile beams is known, the shaped stones are first pushed onto the base of a support during the manufacture of the ceiling, so that the foot is completely covered and then the support is placed on its support and Ceiling stones are used between two beams, which are placed on the sloping stones so that the underside of the ceiling is completely flat.

Die Erfindung hat zum Ziel, ein verbessertes Isolierelement der erwähnten Art zu schaffen.The aim of the invention is to provide an improved insulating element of the type mentioned.

Das wird beim erfindungsgemässen Isolierelement dadurch erreicht, dass der plattenförmige Teil des Isolierelementes an beiden gegenüber liegenden Seiten mit ein Ganzes mit dem plattenförmigen Teil bildenden vorstehenden Befestigungsteilen versehen ist, die gegenseitig spiegelbildlich angeordnet sind und zueinander gerichtete nasenförmige Vorsprünge haben, derart, dass das Isolierelement im voraus von einem Kopfende eines Balkens über die daran ausgebildeten nasenförmigen Vorsprünge geschoben werden kann, und nach der Anordnung des Balkens die gegenüber liegenden Verbindungsteile benachbarter Elemente mit ihren Seitenflächen aneinander anliegen.This is achieved in the insulating element according to the invention in that the plate-shaped part of the insulating element is provided on both opposite sides with a whole with the plate-shaped part projecting fastening parts, which are mutually arranged in mirror image and have mutually directed nose-shaped projections, such that the insulating element in can be pushed in advance from a head end of a beam over the nose-shaped projections formed thereon, and after the arrangement of the beam, the opposite connecting parts of adjacent elements lie against one another with their side faces.

Die erfindungsgemässen Isolierelemente können auf diese Weise im voraus auf die Balken geschoben werden, was im Betrieb erfolgen kann, wo die Balken hergestellt werden, so dass auf der Baustelle die Balken nur montiert zu werden brauchen.In this way, the insulating elements according to the invention can be pushed onto the beams in advance, which can take place during operation, where the beams are produced, so that the beams only need to be assembled on the construction site.

Vorzugsweise haben die Befestigungsteile einen in der Längsrichtung parallel zum Balken verlaufenden Hohlraum, welcher nach der Erfindung dadurch erhalten wird, dass in der Seitenfläche jedes Befestigungselementes eine Ausnehmung ausgebildet ist, derart, dass im montierten Zustand die Ausnehmungen zweier aneinander anliegender Befestigungsteile miteinander den erwähnten Hohlraum abschliessen.The fastening parts preferably have a cavity running in the longitudinal direction parallel to the beam, which is obtained according to the invention in that a recess is formed in the side face of each fastening element, such that in the assembled state, the recesses of two fastening parts lying against one another close off the cavity mentioned .

Auf diese Weise wird nicht nur eine Einsparung an Material der Isolierelemente erhalten, sondern es wird noch die Möglichkeit geschaffen, durch einfaches Abschneiden des oberen Teiles eines oder beider aneinander anliegender Verbindungsteile zweier nebeneinander befindlichen Isolierelemente ein Passstück einzusetzen oder einen ausfüllenden Betonbalken zu bilden, dort, wo der Boden eine besonders grosse Belastung aufnehmen können muss.In this way, not only is a saving in the material of the insulating elements obtained, but the possibility is also created of simply inserting a fitting piece or forming a filling concrete beam by simply cutting off the upper part of one or both connecting parts of two adjacent insulating elements located next to one another, there, where the floor must be able to absorb a particularly large load.

Vorzugsweise weist das erfindungsgemässe Isolierelement eine derartige Länge auf, dass eine Mehrzahl mit ihren Enden aneinander stossender Elemente eine gesamte Länge aufweist, die gleich ist, wie die Länge des Balkens vermindert um die Länge der Auflageteile des Balkens.The insulating element according to the invention preferably has a length such that a plurality of elements which abut one another with their ends have an overall length which is the same as the length of the beam, reduced by the length of the support parts of the beam.

Auf diese Weise können im Betrieb, wo die Balken hergestellt werden, jeweils eine Mehrzahl von Isolierelementen derart auf den Balken geschoben werden, dass an mindestens zwei Stellen, die sich im Abstand von den Enden des Balkens befinden, ein Zwischenraum zwischen den Isolierelementen gebildet wird. In diesen Zwischenräumen können dann Stützhölzer oder ähnliche Organe angeordnet werden, mit deren Hilfe der Balken auf einem darunter gelegenen Balken abgestützt ist, derart, dass die Balken für den Transport oder die Lagerung aufeinander gestapelt werden können, ohne Gefahr einer Beschädigung der Isolierelemente.In this way, in operation, where the beams are manufactured, a plurality of insulating elements can be pushed onto the beams in such a way that at least two points that are at a distance from the ends of the Beam are located, a space between the insulating elements is formed. In these spaces, support beams or similar organs can then be arranged, with the aid of which the beam is supported on a beam located underneath, in such a way that the beams can be stacked on top of one another for transport or storage, without the risk of damaging the insulating elements.

Die Erfindung wird im folgenden anhand in der Zeichnung dargestellter Ausführungsbeispiele erläutert. Es zeigt :

  • Figur 1 einen Querschnitt eines an einem Bodenbalken angebrachten erfindungsgemässen Isolierelementes,
  • Figur 2 einen Teilschnitt eines Bodens, der aus einer Mehrzahl von Bodenbalken mit angebrachten Isolierelementen zusammengesetzt ist,
  • Figur 3 in Schnittdarstellung die Möglichkeit der Ausbildung eines ausfüllenden Stützbalkens zwischen zwei Bodenbalken.
The invention is explained below with reference to exemplary embodiments shown in the drawing. It shows :
  • FIG. 1 shows a cross section of an insulating element according to the invention attached to a floor beam,
  • FIG. 2 shows a partial section of a floor, which is composed of a plurality of floor beams with attached insulating elements,
  • Figure 3 shows in section the possibility of forming a filling support beam between two floor beams.

Wie in der Figur 1 dargestellt ist, hat der Bodenbalken 1 in seinem unteren Bereich nasenförmige Vorsprünge 2, auf welchen ein Isolierelement 3 angebracht ist.As shown in FIG. 1, the bottom beam 1 has nose-shaped projections 2 in its lower region, on which an insulating element 3 is attached.

Das Isolierelement 3 enthält einen plattenförmigen 4 sowie mit diesem ein Stück bildende vorstehende Rippen 5, 6, welche Befestigungsteile bilden, mit deren Hilfe das Isolierelement 3 am Bodenbalken 1 befestigt ist, und zwar mittels der nasenförmigen Vorsprünge 7, 8, die einander zugewandt sind, und auf nasenförmigen Vorsprüngen 2 des Bodenbalkens abgestützt sind. Die nasenförmigen Vorsprünge 7, 8 sind an Teilen 9, 10 ausgebildet, welche den Zwischenraum 11 zwischen zwei nebeneinander angeordneten Bodenbalken mindestens teilweise ausfüllen, wie in der Figur 2 dargestellt ist. Die Verbindungsteile 9, 10 sind gegenseitig spiegelbildlich angeordnet, wobei Teile 9, 10 zweier nebeneinander angeordneter Isolierelemente aneinander entlang einer Naht 12 aufliegen.The insulating element 3 contains a plate-shaped 4 and with this a piece of projecting ribs 5, 6, which form fastening parts with the aid of which the insulating element 3 is fastened to the floor beam 1, namely by means of the nose-shaped projections 7, 8, which face one another, and are supported on nose-shaped projections 2 of the floor beam. The nose-shaped projections 7, 8 are formed on parts 9, 10, which at least partially fill the intermediate space 11 between two floor beams arranged next to one another, as shown in FIG. The connecting parts 9, 10 are mutually arranged in mirror image, parts 9, 10 of two insulating elements arranged next to one another resting against one another along a seam 12.

In den freien Seitenflächen der Befestigungsteile 9, 10 sind Ausnehmungen 13 bzw. 14 ausgebildet, welche gemeinsam einen Hohlraum begrenzen, der sich senkrecht zur Zeichnungsebene über die ganze Länge der Rippen 5, 6 erstreckt.In the free side surfaces of the fastening parts 9, 10, recesses 13 and 14 are formed, which together delimit a cavity which extends perpendicular to the plane of the drawing over the entire length of the ribs 5, 6.

Wie in der Figur 3 dargestellt ist, können die oberen Teile der Verbindungsteile 9, 10 aufgeschnitten werden, derart, dass dann nach oben offene Ausnehmungen 13, 14 entstehen, die einen Kanal bilden, in welchem ein füllender Stützbalken gebildet werden kann, dadurch, dass zuerst eine Armierung 15 in den Kanal 13, 14 eingelegt wird und darauf in den Kanal Beton gegossen wird.As shown in FIG. 3, the upper parts of the connecting parts 9, 10 can be cut open in such a way that recesses 13, 14 open at the top are formed, which form a channel in which a filling support beam can be formed, in that first a reinforcement 15 is placed in the channel 13, 14 and then poured into the channel concrete.

Wenn es bei der Herstellung eines Bodens notwendig ist, einen Bodenbalken in einem grösseren Abstand vom nächst liegenden Bodenbalken anzuordnen, wie dies im rechten Teil der Figur 2 dargestellt ist, derart, dass ein Zwischenraum 16 zwischen den Isolierelementen offen bleibt, kann gemäss der Erfindung auf einfache Weise ein Passstück 17 angebracht werden. Dabei ist erst der oberste Teil des Verbindungsteiles 9 des in der Figur 2 an der rechten Seite angeordneten Isolierelementes 3 aufgeschnitten, so dass das Passstück 17 von oben in die Ausnehmungen 13 und 14 eingelegt werden kann.If, during the production of a floor, it is necessary to arrange a floor beam at a greater distance from the closest floor beam, as is shown in the right part of FIG a fitting piece 17 can be attached in a simple manner. Only the uppermost part of the connecting part 9 of the insulating element 3 arranged on the right in FIG. 2 is cut open, so that the fitting 17 can be inserted into the recesses 13 and 14 from above.

Die lsolierelemente 3 werden im voraus von einem Ende über den Balken 2 geschoben, worauf der Balken 1 im Bauwerk montiert werden kann. Darauf werden die Zwischenräume zwischen den benachbarten Bodenbalken und über den Isolierelementen voll mit Beton ausgegossen. Eventuell kann darauf auf diesem Beton und den Balken 1 eine Deckschicht angebracht werden.The insulating elements 3 are pushed in advance from one end over the beam 2, whereupon the beam 1 can be mounted in the building. The spaces between the adjacent floor beams and over the insulating elements are then fully poured with concrete. A cover layer can possibly be applied to this concrete and the beams 1.
