Description

Die Erfindung betrifft einen Abstandshalter für die Befestigung eines Gegenstandes an einem eine Dämmschicht aufweisenden Untergrund. Zur thermischen Isolierung von Wänden eines Gebäudes werden diese vielfach mit einer Dämmschicht versehen. Die Dicke derartiger Dämmschichten beträgt bis zu 20 cm. Die Dämmschichten bestehen vielfach aus Materialien, die eine geringe mechanische Festigkeit aufweisen. Zerstörungsfrei lassen sich daher an der Dämmschicht regelmäßig keine schweren Gegenstände befestigen. Zur Befestigung schwerer Gegenstände erfolgt daher regelmäßig eine Verankerung durch die Dämmschicht hindurch an der Wand mit einem gattungsgemäßen Abstandshalter.The invention relates to a spacer for the attachment of an object to a substrate having an insulating layer. For thermal insulation of walls of a building, these are often provided with an insulating layer. The thickness of such insulation layers is up to 20 cm. The insulating layers are often made of materials that have low mechanical strength. Therefore, you can not attach heavy objects to the insulation layer without being destroyed. To attach heavy items is therefore regularly anchoring through the insulation layer through the wall with a generic spacer.

Aus der WO 2012/097392 A1 ist ein Abstandshalter zur Verankerung von Gegenständen durch die Dämmschicht hindurch an einer Wand bekannt. Der bekannte Abstandshalter weist ein Abstützelement auf, das wenigstens eine Auflagefläche am Untergrund hat. Das Abstützelement wird an einem im Untergrund verankerten Stabelement befestigt und besteht insbesondere aus einer Platte, die aus Metall gefertigt ist und flach auf der Wand aufliegt. Mit dem Abstützelement ist ein Überbrückungselement verbunden. Das Überbrückungselement besteht aus einem Rohr, das aus Metall gefertigt ist. Die Verbindung des Überbrückungselementes mit dem Abstützelement besteht insbesondere in einer Verschweißung. An dem Überbrückungselement ist ein Montageelement in unterschiedlichen Abständen zur Wand befestigbar. Das Montageelement ist für die eigentliche Befestigung des Gegenstandes erforderlich. Das Montageelement ist vorzugsweise mit einem Außengewinde versehen, mit dem es soweit in ein korrespondierendes Innnengewinde des Überbrückungselements hineingedreht wird, dass es auf der der Wand abgewandten Seite bündig mit der Dämmschicht abschließt. Zur Befestigung des Gegenstandes an dem Montageelement weist das Montageelement auf der der Wand abgewandten Seite wenigstens eine Bohrung auf, in die ein Befestigungselement, wie beispielsweise ein Dübel, eingeführt werden kann.From the WO 2012/097392 A1 For example, a spacer for anchoring objects through the insulating layer to a wall is known. The known spacer has a support element which has at least one support surface on the ground. The support element is fastened to a rod element anchored in the ground and consists in particular of a plate which is made of metal and rests flat on the wall. With the support element, a bridging element is connected. The bridging element consists of a tube made of metal. The connection of the bridging element with the support element is in particular in a weld. At the bridging element, a mounting element at different distances from the wall can be fastened. The mounting element is required for the actual attachment of the object. The mounting element is preferably provided with an external thread, with which it is screwed so far into a corresponding Innnengewinde the bridging element, that it terminates flush with the insulating layer on the side facing away from the wall. For attachment of the article to the mounting element, the mounting element on the side facing away from the wall at least a bore into which a fastener, such as a dowel, can be inserted.

Die Montage des bekannten Abstandshalters ist recht aufwändig und erfolgt in fünf Schritten, die für die Befestigung des Gegenstandes zwingend notwendig sind:

  • In einem ersten Schritt wird die Dämmschicht in dem Bereich, in dem der Abstandshalter an der Wand montiert werden soll, abgetragen.
  • In einem zweiten Schritt wird das Stabelement in dem Untergrund verankert.
  • In einem dritten Schritt werden das Abstützelement und der damit verbundene Abstandshalter über das Stabelement geschoben und im Inneren des Abstandshalters mit einer Mutter befestigt.
  • In einem vierten Schritt wird das Montageelement an dem Überbrückungselement angebracht.
  • In einem fünften Schritt wird schließlich der Gegenstand mittels des Befestigungsmittels an dem Montageelement befestigt.
The installation of the known spacer is quite complex and takes place in five steps, which are absolutely necessary for the attachment of the object:
  • In a first step, the insulating layer in the area in which the spacer is to be mounted on the wall, removed.
  • In a second step, the rod element is anchored in the ground.
  • In a third step, the support element and the associated spacer are slid over the rod element and fastened inside the spacer with a nut.
  • In a fourth step, the mounting element is attached to the bridging element.
  • Finally, in a fifth step, the object is fastened to the mounting element by means of the fastening means.

Aus der DE 20 2012 102 512 U1 ist ein Abstandshalter für die Befestigung eines Gegenstandes an einem eine Dämmschicht aufweisenden Untergrund bekannt, wobei der Abstandshalter eine an dem Untergrund zur Anlage bringbare Auflagefläche, ein im Untergrund verankerbares Stabelement und ein wärmeisolierendes Überbrückungselement aufweist. Das Überbrückungselement ist als zylindrischer Körper ausgebildet und besteht aus einem wärmeisolierenden Material. In ein Innengewinde des Überbrückungselementes ist von einer Seite das Stabelement und von der anderen Seite das Befestigungselement für den zu befestigenden Gegenstand eingeschraubt. Zwischen den Stirnseiten des Stabelementes und des Befestigungselementes ist ein Abstand vorgesehen, so dass eine Wärmebrücke vermieden wird. Die Länge des Überbrückungselementes ist an die Dicke der Dämmschicht angepasst.From the DE 20 2012 102 512 U1 a spacer for the attachment of an object to a layer comprising an insulating layer is known, wherein the spacer has a contact surface which can be brought to bear against the substrate, a rod element which can be anchored in the ground and a heat-insulating bridging element. The bridging element is formed as a cylindrical body and consists of a heat-insulating material. In an internal thread of the bridging element, the rod element is screwed in from one side and the fastening element for the object to be fastened from the other side. Between the end faces of the rod element and the fastening element, a distance is provided, so that a thermal bridge is avoided. The length of the bridging element is adapted to the thickness of the insulating layer.

Die EP 2 466 024 A2 offenbart einen Abstandshalter für die Befestigung eines Gegenstandes an einem eine Dämmschicht aufweisenden Untergrund. Die Stirnseite des Überbrückungselementes befindet sich in einem Abstand zu dem Untergrund, in dem das Stabelement verankert ist. Von der anderen Stirnseite greift in das Überbrückungselement ein Befestigungselement in ein Innengewinde ein. Das Überbrückungselement trennt das Stabelement thermisch von dem Befestigungselement und weist eine Nut auf, die der Aufnahme eines Manipulierelementes für eine Siebhülse dient, mit der das Stabelement in dem Untergrund verankert wird.The EP 2 466 024 A2 discloses a spacer for securing an article to a substrate having an insulating layer. The front side of the bridging element is located at a distance to the ground in which the rod element is anchored. From the other end engages in the bridging element a fastener in an internal thread. The bridging element thermally separates the rod member from the fastener and has a groove which serves to receive a manipulating element for a screen sleeve, with which the rod element is anchored in the ground.

Die DE 20 2012 101 506 U1 E2 offenbart einen Ankerkörper zum Befestigen eines Gegenstandes, wie beispielsweise einer Markise, an einem eine Dämmschicht aufweisenden Mauerwerk. In die Dämmschicht und das Mauerwerk wird zum Einsetzen des zylindrischen Ankerkörpers ein Sackloch eingebracht. Der Ankerkörper besitzt an seinem in Einschubrichtung in das Sackloch vorderen Ende eine von mehreren Umfangsnuten gebildete Nutenzone am Außenmantel zur Aufnahme eines Verbundmörtels, mit dem der Ankerkörper im Mauerwerk festgesetzt wird. In der Mantelfläche des Ankerkörpers ist ein axialer Zuführkanal vorgesehen, der zum Einbringen des unter Druck stehenden Verbundmörtels nach dem Einsetzen des Ankerkörpers in das Mauerwerk bestimmt ist. In den bis zur Nutenzone führenden Zuführkanal wird ein Verfüll-Schlauch eingesetzt, über den der Verbundmörtel unter Druck in die Nutenzone eingebracht wird.The DE 20 2012 101 506 U1 E2 discloses an anchor body for securing an article, such as an awning, to a masonry having an insulating layer. In the insulating layer and the masonry, a blind hole is inserted for insertion of the cylindrical anchor body. The anchor body has at its front end in the insertion direction into the blind hole a groove zone formed by a plurality of circumferential grooves on the outer jacket for receiving a composite mortar with which the anchor body is fixed in the masonry. In the lateral surface of the anchor body, an axial feed channel is provided, which is intended for introducing the pressurized composite mortar after insertion of the anchor body in the masonry. In the leading to the groove zone feed channel, a filling hose is used, through which the composite mortar is introduced under pressure into the groove zone.

Die EP 1 882 787 A2 offenbart den Gegentand des Oberbegriffs des Anspruchs 1 der Erfindung.The EP 1 882 787 A2 discloses the opposite of the preamble of claim 1 of the invention.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, einen universell einsetzbaren Abstandshalter der eingangs erwähnten Art zu schaffen, der einfacher aufgebaut ist und dessen Montage an dem Untergrund erheblich vereinfacht wird bei zugleich verbesserter Kraftübertragung von dem befestigten Gegenstand in die Verankerung in dem Untergrund. Außerdem soll der Abstandhalter ohne Beeinträchtigung der Wärmedämmung in einer Standardlänge in unterschiedlich starken Dämmschichten zum Einsatz gelangen können.Based on this prior art, the present invention seeks to provide a universally applicable spacer of the type mentioned above, which is simpler and its mounting on the ground is greatly simplified at the same time improved power transmission from the fastened object into the anchorage in the underground. In addition, the spacer should be able to use without affecting the thermal insulation in a standard length in different thickness insulation layers.

Diese Aufgabe wird durch einen Abstandshalter mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a spacer with the features of claim 1.

Die Wärmeleitung zwischen dem im Untergrund verankerbaren Stabelement einerseits und dem Befestigungsmittel andererseits wird durch nur ein Bauteil, nämlich das Überbrückungselement, unterbrochen. Hierdurch wird der Aufbau des Abstandshalters und dessen Montage an dem Untergrund erheblich vereinfacht. Zugleich wird die Kraftübertragung von dem befestigten Gegenstand in die Verankerung in dem Untergrund verbessert. Zur thermischen Trennung des Stabelementes und des Befestigungsmittel besteht das Überbrückungselement vorzugsweise aus thermisch isolierendem Material.The heat conduction between the anchored in the ground bar element on the one hand and the fastener on the other hand is interrupted by only one component, namely the bridging element. As a result, the structure of the spacer and its mounting on the ground is considerably simplified. At the same time, the transmission of power from the fastened object to the anchoring in the ground is improved. For thermal separation of the rod element and the fastening means, the bridging element preferably consists of thermally insulating material.

Die Befestigung des Überbrückungselementes wird dadurch erleichtert, dass das Überbrückungselement mit seinem Innengewinde unmittelbar auf das Außengewinde des Stabelementes aufschraubbar ist. Zur Befestigung des Gegenstandes wird das Befestigungsmittel mit seinem Außengewinde unmittelbar in das Innengewinde des Überbrückungselementes eingeschraubt. Sofern nur ein durchgehendes, sich in Richtung der Längsachse des Überbrückungselementes von der Deckfläche zur Grundfläche erstreckendes Innengewinde vorgesehen ist, muss zur thermischen Entkopplung zwischen den eingeschraubten metallischen Außengewinden von Stab- und Befestigungselement ein Abstand verbleiben. Außerdem darf das Innengewinde nicht aus einem thermisch gut leitendem Material, beispielsweise Metall bestehen. Sofern ein sich von der Grundfläche erstreckendes Innengewinde und ein sich von der Deckfläche erstreckendes Innengewinde vorgesehen sind, die im Abstand zueinander in dem Überbrückungselement enden, können die Innengewinde auch aus Metall bestehen.The attachment of the bridging element is facilitated by the fact that the bridging element is screwed with its internal thread directly on the external thread of the rod element. For attachment of the article, the fastening means is screwed with its external thread directly into the internal thread of the bridging element. If only a continuous, extending in the direction of the longitudinal axis of the bridging element from the top surface to the base surface extending internal thread, a distance must remain for thermal decoupling between the screwed metallic external threads of rod and fastener. In addition, the internal thread must not consist of a thermally well conductive material, such as metal. If an internal thread extending from the base surface and an internal thread extending from the top surface are provided which terminate at a distance from one another in the bridging element, the internal threads can also be made of metal.

Zwischen dem Abstandshalter und der Dämmschicht entstehen regelmäßig Lücken, insbesondere in Form eines das Überbrückungselement umgebenden Ringspaltes. Um diese Lücken mit einem Isoliermaterial, insbesondere einem Polyurethanschaum, auszufüllen, weist das Überbrückungselement die mindestens eine sich zwischen dessen Grund- und Deckfläche erstreckende, durchlaufende Nut auf. Der Isolierschaum füllt den Ringspalt sowie ggf. dem Raum zwischen dem Überbrückungselement und dem Abschussadapter aus. Ohne Beeinträchtigung der Wärmedämmung kann der erfindungsgemäße Abstandshalter daher in einer Standardlänge in unterschiedlich starken Dämmschichten zum Einsatz gelangen. Der in unterschiedlichem Abstand zur Grundfläche des Überbrückungselementes befestigbare Abschlussadapter verschließt die den Abstandshalter aufnehmende und ausgeschäumte Höhlung in der Dämmschicht.Gaps regularly occur between the spacer and the insulating layer, in particular in the form of an annular gap surrounding the bridging element. To fill these gaps with an insulating material, in particular a polyurethane foam, the bridging element has the at least one continuous groove extending between its base and top surfaces. The insulating foam fills the annular gap and possibly the space between the bridging element and the launching adapter. Without impairing the thermal insulation of the spacer according to the invention can therefore be used in a standard length in different thicknesses insulating layers used. The fastened at different distances from the base of the bridging element termination adapter closes the spacer receiving and foamed cavity in the insulation layer.

Um das Überbrückungselement mithilfe eines Einschraubwerkzeugs auf das Stabelement aufschrauben zu können, ist mit der Grundfläche des Überbrückungselementes vorzugsweise ein Körper mit prismatischer Außenkontur drehfest verbunden. Die prismatische Außenkontur dient insbesondere zur Verbindung mit einem Schraubenschlüssel. Durch das Anziehen des Überbrückungselementes gelangt die Auflagefläche des Abstandshalters gegen den Untergrund, wodurch eine hohe Stützkraft erzielt wird.In order to be able to screw the bridging element onto the rod element with the aid of a screwing-in tool, preferably a body having a prismatic outer contour is non-rotatably connected to the base surface of the bridging element. The prismatic outer contour is used in particular for connection with a wrench. By tightening the bridging element, the support surface of the spacer reaches the ground, whereby a high supporting force is achieved.

Um den Abstandshalter für die Befestigung sehr schwerer Gegenstände einsetzen zu können, ist es in einer Ausgestaltung der Erfindung vorgesehen, dass eine insbesondere metallische Hülse das Überbrückungselement zumindest auf einer Teillänge, vorzugsweise über die gesamte Länge, umgibt, wobei die Innenfläche der Hülse bündig an der Mantelfläche des Überbrückungselementes anliegen kann.In order to use the spacer for attaching very heavy objects, it is provided in one embodiment of the invention that a particular metallic sleeve surrounds the bridging element at least over a partial length, preferably over the entire length, wherein the inner surface of the sleeve flush with the Cloak surface of the bridging element can rest.

Um den stirnseitigen Rand mit dem Anzugsmoment des Überbrückungselementes an dem Untergrund zur Anlage zu bringen, ist im Inneren der Hülse ein Fixierelement mit einem Durchgang für das Stabelement befestigt, wobei der Durchgang mit der Zugangsöffnung in der Deckfläche des Überbrückungselementes fluchtet. Durch Anziehen des Überbrückungselementes wird über die Deckfläche des Überbrückungselementes die Kraft auf das Fixierelement übertragen, so dass der äußere Rand der Hülse infolgedessen als Auflagefläche gegen den Untergrund gedrückt wird. Sofern ein plattenförmiges Fixierelement bündig mit der Stirnseite der Hülse abschließt, gelangt das Fixierelement als Anlagefläche bündig an den Untergrund zur Anlage.In order to bring the front edge to the ground with the tightening torque of the bridging element, a fixing element with a passage for the rod element is fixed inside the sleeve, wherein the passage is aligned with the access opening in the top surface of the bridging element. By tightening the bridging element, the force is transmitted to the fixing over the top surface of the bridging element, so that the outer edge of the sleeve is consequently pressed as a bearing surface against the ground. If a plate-shaped fixing element terminates flush with the end face of the sleeve, the fixing element comes as a contact surface flush with the substrate to the plant.

Um den über die Nuten in dem Überbrückungselement zugeführten Isolierschaum auch bei Verwendung einer das Überbrückungselement umgebenden Hülse in dem Ringspalt zur Wirkung zu bringen, weist die Hülse sich in Richtung des Überbrückungselementes erstreckende Durchtrittsöffnungen auf.In order to bring the insulating foam supplied via the grooves in the bridging element into effect even when using a sleeve surrounding the bridging element in the annular gap, the sleeve has passage openings extending in the direction of the bridging element.

Damit der Isolierschaum bis an die Oberfläche des Untergrundes, insbesondere bis an die Wand gelangt, weist das Fixierelement in vorteilhafter Ausgestaltung der Erfindung mindestens eine Durchtrittsöffnung für den Isolierschaum auf.So that the insulating foam reaches the surface of the substrate, in particular up to the wall, the fixing element in an advantageous embodiment of the invention has at least one passage opening for the insulating foam.

Um nach Montage des Abstandshalters einen sauberen Abschluss an der Außenfläche der Dämmschicht sicherzustellen, weist der Abstandshalter den Abschlussadapter auf. Der Abschlussadapter weist vorzugsweise eine kreisförmige Platte mit einem Randbereich auf, der an der Dämmschicht zur Anlage bringbar ist.To ensure a clean seal on the outer surface of the insulation layer after mounting the spacer, the spacer has the termination adapter. The termination adapter preferably has a circular plate with an edge region which can be brought to bear against the insulating layer.

Von der kreisförmigen Platte erstreckt sich ein rohrförmiger Ansatz in Richtung des Überbrückungselementes, den der Randbereich umgibt. Der rohrförmige Ansatz des Abschlussadapters weist vorzugsweise ein Innengewinde auf, das auf die Gewindestange in dem gewünschten Abstand zur Grundfläche des Überbrückungselementes aufgeschraubt ist. Hierdurch lassen sich die unterschiedlichen Stärken der Dämmschicht durch mehr oder weniger weites Aufschrauben des Abschlussadapters auf das als Gewindestange ausgebildete Befestigungsmittel ausgleichen.From the circular plate extends a tubular projection in the direction of the bridging element, which surrounds the edge region. The tubular extension of the termination adapter preferably has an internal thread which is screwed onto the threaded rod at the desired distance from the base surface of the bridging element. This can be done compensate for the different thicknesses of the insulating layer by more or less screwing the termination adapter on the designed as a threaded rod fasteners.

Insbesondere wenn der Abschlussadapter mit einer das Überbrückungselement umgebenden metallischen Hülse in Berührung gelangt, besteht dieser zur Vermeidung von Kältebrücken vorzugsweise aus einem wärmeisolierenden Material. Zu einer Berührung zwischen der Hülse und dem Abschlussadapter kann es insbesondere dann kommen, wenn die Hülse einen die Grundfläche des Überbrückungselementes überragenden Abschnitt mit einem Innengewinde aufweist und auf dem rohrförmigen Ansatz des Abschlussadapters ein Außengewinde angeordnet ist, das in das Innengewinde des überragenden Abschnitts einschraubbar ist.In particular, when the termination adapter comes into contact with a metallic sleeve surrounding the bridging element, it preferably consists of a heat-insulating material to avoid cold bridges. It may come to a contact between the sleeve and the termination adapter in particular when the sleeve has a the base of the bridging member superior portion with an internal thread and on the tubular extension of the end adapter, an external thread is arranged, which is screwed into the internal thread of the projecting portion ,

Der in Figur 1 dargestellte Abstandshalter besteht aus

  • einem Stabelement (1), das als Gewindestange M12, M16 oder M20 ausgebildet ist,
  • einem Überbrückungselement (3) aus Kunststoff,
  • einem als Gewindestange ausgebildeten Befestigungsmittel (4) mit einem Außengewinde,
  • einem Abschlussadapter (5) aus Kunststoff mit einem Innengewinde und
  • eine Durchtrittsöffnung (13) in Form eines Einfüllstutzens für die Zufuhr eines Isolierschaums.
The in FIG. 1 shown spacer consists of
  • a rod element (1), which is designed as a threaded rod M12, M16 or M20,
  • a bridging element (3) made of plastic,
  • a fastening means (4) designed as a threaded rod with an external thread,
  • a termination adapter (5) made of plastic with an internal thread and
  • a passage opening (13) in the form of a filler neck for the supply of a Isolierschaums.

Der in Figur 1 dargestellte Abstandshalter ist für leichte bis mittelschwere Lasten vorgesehen. Das als Gewindestange ausgebildete Stabelement (1) wird am Untergrund, insbesondere einer Rohbauwand, verankert. Auf die Gewindestange (1) wird das ein Innengewinde aufweisende Überbrückungselement (3) aufgeschraubt, bis die Deckfläche des Überbrückungselementes bündig an dem Untergrund zur Anlage gelangt. Bei diesem Ausführungsbeispiel bildet die Deckfläche des Überbrückungselementes (3) die Anlagefläche an dem Untergrund. Das Innengewinde des Überbrückungselementes (3) weist eine weitere Zugangsöffnung in der gegenüberliegenden Grundfläche auf. In diese Zugangsöffnung in der Grundfläche ist das als Gewindestange ausgebildete Befestigungsmittel (4) in das Innengewinde eingeschraubt.The in FIG. 1 shown spacers is intended for light to medium loads. Trained as a threaded rod rod element (1) is anchored to the substrate, in particular a shell wall. On the threaded rod (1), the internal thread having a bridging element (3) is screwed until the top surface of the bridging element comes flush to the ground to the plant. In this embodiment, the top surface of the bridging element (3) forms the contact surface on the ground. The internal thread of the bridging element (3) has a further access opening in the opposite base area. In this access opening in the base of the threaded rod formed as a fastening means (4) is screwed into the internal thread.

Auf dem Befestigungsmittel (4) ist der Abschlussadapter (5) aufgeschraubt. Der Abstand zur Grundfläche des Überbrückungselementes (3) lässt sich durch mehr oder weniger weites Aufschrauben des Abschlussadapters (5) an die Stärke der in Figur 1 nicht dargestellten Dämmschicht anpassen.On the fastening means (4) of the termination adapter (5) is screwed. The distance to the base of the bridging element (3) can be adjusted by more or less wide screwing the termination adapter (5) to the thickness of the insulating layer, not shown in Figure 1.

Der Abschlussadapter (5) weist eine Durchtrittsöffnung (13) für die Zufuhr eines Isolierschaums auf. Durch diese Durchtrittsöffnung (13) kann beispielsweise ein Polyurethanschaum in den das Überbrückungselement (3) umgebenden Ringspalt sowie ggf. den Zwischenraum zwischen dem Überbrückungselement (3) und dem Abschlussadapter (5) eingebracht werden. Der Isolierschaum gelangt auf der gesamten Länge des Überbrückungselementes durch die Nuten (14) bis an die Innenwand des Bohrlochs zur Aufnahme des Anschlussadapters.The termination adapter (5) has a passage opening (13) for the supply of an insulating foam. Through this passage opening (13), for example, a polyurethane foam in the bridging element (3) surrounding annular gap and possibly the space between the bridging element (3) and the termination adapter (5) are introduced. The insulating foam passes over the entire length of the bridging element through the grooves (14) to the inner wall of the borehole for receiving the connection adapter.

Nach dem Einbringen des Isolierschaums wird die Durchtrittsöffnung (13) mit einem Stopfen verschlossen, so dass kein Schaum austreten kann.After introducing the insulating foam, the passage opening (13) is closed with a stopper, so that no foam can escape.

Wie aus Figur 1 erkennbar besteht der Abschlussadapter (5) im Wesentlichen aus einer kreisförmigen Platte mit einem Randbereich, der an der Dämmschicht zur Anlage gelangt. Von der kreisförmigen Platte erstreckt sich ein rohrförmiger Ansatz in Richtung des Überbrückungselementes (3). Der rohrförmige Ansatz wird von dem Randbereich umgeben. Durch Verdrehen des Abschlussadapters (5), wobei die Durchtrittsöffnung (13) für den Isolierschaum aus der Flucht der Nuten (14) gelangt, kann ebenfalls ein Austreten des Isolierschaums verhindert werden. Vorteile des Abstandshalters nach Figur 1 sind Folgende:

  • In etwa gleiche Biegezugwerte gegenüber reiner Gewindestange bei weniger Gewindestangendurchmesser (M12 zu M16)
  • Noch höhere Biegezugwerte bei M16 oder größer
  • nochmalige Erhöhung der Biegezugwerte durch größere Kunststoff- Überbrückungselemente
  • Taupunktentstehung an der Rohbauwand wird berücksichtigt bzw. verhindert
  • Stufenlose Längenregulierung (kein Absägen von Gewindestangen auf der Baustelle)
  • Unterbrechung der Gewindestangen durch Kunststoff. Überbrückungselement (keine Kältebrücke)
  • Kein Austreten von PU-Schaum nach vorne möglich.
How out FIG. 1 The termination adapter (5) is essentially made up of a circular plate with an edge region which comes into contact with the insulating layer. From the circular plate, a tubular extension extends in the direction of the bridging element (3). The tubular extension is surrounded by the edge region. By turning the end adapter (5), wherein the passage opening (13) for the insulating foam from the alignment of the grooves (14) passes, also a leakage of the insulating foam can be prevented. Advantages of the spacer after FIG. 1 are the following:
  • Approximately the same bending tensile values compared to a pure threaded rod with a smaller threaded rod diameter (M12 to M16)
  • Even higher bending tensile values for M16 or larger
  • Another increase in the bending tensile values due to larger plastic bridging elements
  • Dew point formation on the shell wall is considered or prevented
  • Stepless length adjustment (no sawing of threaded rods on the construction site)
  • Breakage of the threaded rods by plastic. Bridging element (no cold bridge)
  • No leakage of PU foam forward possible.

  • einen Abschlussadapter (5) aus Kunststoff mit einem mittig angeordneten Innengewinde,
  • ein an der linken Stirnseite der Hülse (2) befestigtes Fixierelement (6) in Form einer Fixierplatte,

    • eine Verklinkerung (11),
    • eine Isolierung (12),
  • eine verschließbare Durchtrittsöffnung (13) für einen Isolierschaum,
  • in dem Überbrückungselement (3) verlaufende Nuten (14),
  • einen Zwischenraum zwischen dem Überbrückungselement (3) und dem Abschlussadapter (5),
  • einen Ringspalt (16) zwischen dem Außenmantel der Hülse (2) und der Innenfläche der Bohrung zur Aufnahme des Anschlussadapters in der Dämmschicht (9),
  • eine Durchtrittsöffnung (17) für einen Isolierschaum in dem plattenförmigen Fixierelement (6).
FIG. 2 shows in perspective view and in a schematic section a spacer for the attachment of very heavy objects. FIG. 2 shows:
  • a rod element (1) designed as a threaded rod M12, M16 or M20,
  • a sleeve (2) made of metal, which has passage openings, in particular in the form of holes or slots, for an insulating foam,
  • a bridging element (3) in the sleeve (2). Furthermore, it can be seen that the sleeve (2) projects beyond the base area of the bridging element (3) on the right front side,
  • a finishing adapter (5) made of plastic with a centrally arranged internal thread,
  • a fixing element (6) fastened to the left end face of the sleeve (2) in the form of a fixing plate,
  • a passage (7) through a central hole in the fixing plate (6) for the rod element (1),
  • a base (8), for example in the form of a wall to which an object is to be attached,
  • an insulating layer (9), for example in the form of a thermal insulation composite system comprising:
    • an insulating plaster (10),
    • a clinker (11),
    • an insulation (12),
  • a closable passage opening (13) for an insulating foam,
  • in the bridging element (3) extending grooves (14),
  • a space between the bridging element (3) and the termination adapter (5),
  • an annular gap (16) between the outer casing of the sleeve (2) and the inner surface of the bore for receiving the connection adapter in the insulating layer (9),
  • a passage opening (17) for an insulating foam in the plate-shaped fixing element (6).

Der in den Figuren 2 a, b dargestellte Abstandshalter ist für sehr schwere Lasten bestimmt.The in the FIGS. 2 a . b shown spacers is intended for very heavy loads.

Die aus Metall bestehende Hülse (2) wird mithilfe des aus Kunststoff bestehenden Überbrückungselementes (3) und dem als Gewindestange ausgebildeten Stabelementes (1) an dem Untergrund (8) in Form des Mauerwerks befestigt. Dabei wird der vordere stirnseitige Rand der Metallhülse (2) gegen das Mauerwerk gedrückt. Mithilfe der Metallhülse (2) lassen sich deutlich höhere Biegezugwerte als bei Lösungen mit reiner Gewindestange erreichen. Die Gewindestange (1) wird in das Überbrückungselement (3) eingeschraubt. Das Überbrückungselement (3) wird mit der Gewindestange (1) in die Hülse aus Metall gesteckt. Dabei wird die Gewindestange (1) durch die Öffnung (7) in der Fixierplatte geschoben, bis das Überbrückungselement mit seiner Deckfläche an der Fixierplatte (6) anliegt. Nun wird die Gewindestange (1) soweit in die Wand geschraubt bzw. geschoben, bis die Hülse (2) mit ihrem stirnseitigen Rand an der Mauer (8) anliegt.The existing metal sleeve (2) is fixed by means of the existing plastic bridging element (3) and designed as a threaded rod rod element (1) on the substrate (8) in the form of masonry. In this case, the front end edge of the metal sleeve (2) is pressed against the masonry. Using the metal sleeve (2) significantly higher bending tensile values can be achieved than with pure threaded rod solutions. The threaded rod (1) is screwed into the bridging element (3). The bridging element (3) is inserted with the threaded rod (1) in the sleeve of metal. In this case, the threaded rod (1) is pushed through the opening (7) in the fixing plate until the bridging element rests with its top surface on the fixing plate (6). Now the threaded rod (1) as far screwed into the wall or pushed until the sleeve (2) rests with its front edge on the wall (8).

In die Grundfläche des Überbrückungselementes (3) gegenüberliegend von der Deckfläche wird das als Gewindestange ausgebildete Befestigungsmittel (4) in das Innengewinde eingeschraubt. Auf die Gewindestange lässt sich der Abschlussadapter (5) im gewünschten Abstand zu der Grundfläche des Überbrückungselementes (3) aufschrauben. Der Abstand wird dabei so gewählt, dass der Randbereich des Abschlussadapters (5) bündig mit der Außenfläche der Dämmschicht (9) abschließt. Da die Gewindestange (1) und das Befestigungsmittel (4) beide in dem Innengewinde des Überbrückungselementes aus Kunststoff aufgenommen werden, sich jedoch stirnseitig nicht berühren, entsteht keine Kältebrücke.In the base of the bridging element (3) opposite the top surface, the fastening means (4) formed as a threaded rod is screwed into the internal thread. The end adapter (5) can be screwed onto the threaded rod at the desired distance from the base of the bridging element (3). The distance is chosen so that the edge region of the end adapter (5) is flush with the outer surface of the insulating layer (9). Since the threaded rod (1) and the fastening means (4) are both received in the internal thread of the bridging element made of plastic, but do not touch the front, no cold bridge.

Durch die Durchtrittsöffnung (13) in dem Abschlussadapter (5) wird durch die Nuten (14) in dem Überbrückungselement (3) ein Isolierschaum, vorzugsweise ein Polyurethanschaum, in die Hülse (2) und den Zwischenraum (15) eingebracht. Durch die Expansion des Isolierschaums tritt dieser auch durch die geschlitzte bzw. gelochte Hülse (2) aus und verfüllt den Ringspalt (16). Durch die Durchtrittsöffnung (17) in der Fixierplatte (6) gelangt der Isolierschaum auch bis an die Mauer (8) heran.Through the passage opening (13) in the end adapter (5) is through the grooves (14) in the bridging element (3) an insulating foam, preferably a polyurethane foam, in the Sleeve (2) and the intermediate space (15) introduced. Due to the expansion of the insulating foam, it also exits through the slotted or perforated sleeve (2) and fills the annular gap (16). Through the passage opening (17) in the fixing plate (6) of insulating foam also reaches up to the wall (8) zoom.

Die Durchtrittsöffnung (13) in dem Abschlussadapter (5) wird nach dem Ausschäumen mit einem Stopfen verschlossen, so dass kein Schaum austreten kann.The passage opening (13) in the end adapter (5) is closed after foaming with a stopper, so that no foam can escape.

Der Abstandshalter nach den Figuren 2 a, b weist folgende Vorteile auf:

  • Bei weitem höhere Biegezugwerte bei weniger Gewindestangendurchmesser (M12 zu M16)
  • Noch höhere Biegezugwerte bei M16 oder größer
  • nochmalige Erhöhung der Biegezugwerte durch größere Metallhülsen bzw. KST- Überbrückungselemente
  • Die Taupunktentstehung an der Rohbauwand wird berücksichtigt bzw. verhindert
  • Stufenlose Längenregulierung
  • Unterbrechung der Gewindestangen durch Kunststoff. Überbrückungselement (keine Kältebrücke)
  • Kein Austreten von PU-Schaum nach vorne möglich.
