Abstract

The spacer has two sections, of which one section carries a retaining element and the other section is held in a wall (W). An insulating element (30) is provided with less heat conduction between the sections, which are formed of anchors (10, 20), where the element is formed of fiber-reinforced composite material. Threaded holes are provided on front sides of the anchors, where threaded ends of the insulating element are screwed into the holes. The anchor (20), which is held in the brickwork, is designed as a multi-sided anchor that exhibits profiles (P) running at the circumference.

Description

Technischer HintergrundTechnical background

Die Erfindung betrifft einen Abstandshalter zur Befestigung eines Halteelementes in einer Wandung mit außen liegender Dämmschicht, mit einem ersten Abschnitt, der das Halteelement trägt, einem zweiten Abschnitt, der in der Wandung gehalten ist, und einem Dämmelement mit geringer Wärmeleitung zwischen dem ersten und zweiten Abschnitt, wobei die beiden Abschnitte so dimensioniert sind, dass das Dämmelement in der Dämmschicht der Wandung zu liegen kommt.The invention relates to a spacer for fastening a retaining element in a wall with an external insulating layer, with a first portion which carries the holding element, a second portion which is held in the wall, and a low thermal conductivity insulating element between the first and second portion , wherein the two sections are dimensioned so that the insulating element comes to rest in the insulating layer of the wall.

Zur Einleitung von Lasten in eine Wandung, beispielsweise zur Halterung einer Markise, eines Klappladens oder sonstiger Gegenstände, bedarf es besonderer Maßnahmen, wenn die Wandung mit einer außen liegenden Dämmschicht versehen ist, da diese in der Regel keine Kräfte aufnehmen kann. Das Halteelement muss daher sicher in einem Abstand zur tragenden Wandung gehalten werden, der etwa der Dicke der Dämmschicht entspricht. Dabei muss darauf geachtet werden, dass durch die konstruktive Verbindung des Halteelementes mit dem in der tragenden Wandung gehaltenen Teil keine Kältebrücke entsteht, hier muss folglich ein Dämmelement mit geringer Wärmeleitung vorgesehen sein.For the introduction of loads in a wall, for example, for holding an awning, a folding shutter or other objects, it requires special measures when the wall is provided with an external insulating layer, as these can absorb in the rule no forces. The holding element must therefore be kept at a safe distance from the supporting wall, which corresponds approximately to the thickness of the insulating layer. It must be ensured that no cold bridge is formed by the constructive connection of the holding element with the part held in the supporting wall, thus an insulating element with low heat conduction must be provided accordingly.

Stand der TechnikState of the art

Aus der DE 10 2005 022 449 A1 ist ein gattungsgemäßer Abstandshalter bekannt, bei dem das Dämmelement als Abstandshülse ausgebildet ist, in den eine in die tragende Wandung ragende Gewindestange einschraubbar ist. An ihrer Stirnseite weist die Abstandshülse eine Aufnahmebohrung für eine Befestigungsschraube als Halteelement auf, mit der dann geeignete weitere Haltebauteile kraftschlüssig in der Wandung fixiert werden können. Die Abstandshülse ist aus einem thermisch wenig leitenden Werkstoff hergestellt, um Kältebrücken zu vermeiden, aus Stabilitätsgründen ist die Gewindestange, die als Ankerbolzen in der Wandung dient, aus Stahl gefertigt.From the DE 10 2005 022 449 A1 a generic spacer is known in which the insulating element is designed as a spacer sleeve into which a protruding into the supporting wall threaded rod can be screwed. At its front side, the spacer sleeve has a receiving bore for a fastening screw as a holding element, with which then suitable further holding components can be fixed non-positively in the wall. The spacer sleeve is made of a thermally less conductive material to avoid cold spots, for reasons of stability, the threaded rod, which serves as an anchor bolt in the wall, made of steel.

Die Verwendung einer im wesentlichen rotationssymmetrischen Gewindestange als Ankerelement, die in diesem Bereich weitgehend üblich ist, ermöglicht auch bei der Fixierung durch Mörtel oder geeignete Klebstoffe, ggf. in einer Siebhülse, einen begrenzten Widerstand gegen die Einwirkung von Drehkräften um deren Längsachse, wie sie beim Einschrauben von Schraubelementen in die nach außen zeigende Stirnseite des Abstandshalters insbesondere dann auftreten können, wenn hierbei größere Hebelelemente zum Tragen kommen.The use of a substantially rotationally symmetrical threaded rod as anchoring element, which is widely used in this area, also allows for fixing by mortar or suitable adhesives, possibly in a sieve sleeve, a limited resistance to the action of rotational forces about the longitudinal axis, as in the Screwing screwing into the outwardly facing end face of the spacer can occur in particular when this larger lever elements come to fruition.

Durch die nur geringe Profilierung der handelsüblichen Gewindestangen ist auch die Widerstandskraft des vorbekannten Abstandshalters gegenüber Zugkräften in seiner Längsachse nur begrenzt.Due to the low profile of the commercial threaded rods and the resistance of the prior art spacer against tensile forces in its longitudinal axis is limited.

DE 199 47 913 A1 beschreibt ein Befestigungselement zur Anbringung von Lasten an einer eine Wärmedämmung aufweisenden Wand. Dieses weist ein zylinderförmiges Isolierelement auf, dessen Länge zumindest der Stärke der zu überbrückenden Wärmedämmung entspricht und das an einem wandseitigen Ende mit einem Gewindeelement verklebt ist. Dieses Gewindeelement besteht alternativ aus einem mit dem Isolierelement verklebten Gewindestab mit Außengewinde, einer an einer Innenseite des Isolierelementes festgelegten Gewindebuchse mit Innengewinde oder einer an einer Außenseite des Isolierelementes festgelegten Gewindehülse. In jedem Fall wird das Gewindeelement bei der Montage des Befestigungselementes mittels einer aushärtbaren Masse in einer Ausnehmung der Wand festgelegt. DE 199 47 913 A1 describes a fastener for attaching loads to a thermal insulation wall. This has a cylindrical insulating element whose length corresponds at least to the thickness of the thermal insulation to be bridged and which is glued to a wall-side end with a threaded element. This threaded member alternatively consists of a bonded to the insulating threaded rod with external thread, a fixed to an inner side of the insulating threaded bushing with internal thread or fixed to an outer side of the insulating threaded sleeve. In any case, the threaded element is fixed during assembly of the fastener by means of a curable material in a recess of the wall.

DE 1 400 932 A1 beschreibt eine Vorrichtung zur schnell aufeinander folgenden Befestigung von mehreren Gewindehülsen an Schalungswänden. Diese Gewindehülsen werden beim Verfüllen der Schalung mit einbetoniert, um ein nachträgliches Bohren von Dübellöchern zu vermeiden. DE 1 400 932 A1 describes a device for fast sequential attachment of several threaded sleeves on formwork walls. These threaded sleeves are embedded in the filling of the formwork in order to avoid subsequent drilling of dowel holes.

FR 1,095,493 A zeigt ein Befestigungselement zur Verwendung mit einer aushärtenden Masse, die zur Erhöhung der Auszugs- und Torsionshaltekräfte schuppenartige Flächen an Ihrem Umfang aufweist. FR 1,095.493 shows a fastener for use with a thermosetting mass, which has scale-like surfaces on its periphery to increase the pull-out and torsional holding forces.

EP 0 167 484 A1 beschreibt ein Befestigungselement mit einem Dübelkörper, der mehrere eingeprägte Bereiche aufweist, die einen vierkantförmigen Querschnitt erzeugen. EP 0 167 484 A1 describes a fastener with a dowel body having a plurality of embossed portions which produce a square shaped cross section.

Darstellung der ErfindungPresentation of the invention

Aufgabe der Erfindung ist es, den gattungsgemäßen Abstandshalter derart weiterzubilden, dass er bei Aufrechterhaltung der Wärmedämmung stabiler sowohl gegenüber Drehkräften als auch gegenüber Zugkräften ist.The object of the invention is to develop the generic spacer such that it is more stable in terms of both the rotational forces and tensile forces while maintaining the thermal insulation.

Erfindungsgemäß wird diese Aufgabe gemäß dem kennzeichnenden Teil des Patentanspruchs 1 gelöst.According to the invention this object is achieved according to the characterizing part of patent claim 1.

Der Grundgedanke der Erfindung ist darin zu sehen, dass durch die Ausbildung von Längskanten und zumindest einer am Umfang verlaufenden Profilierung zumindest bei demjenigen Anker, der im Mauerwerk gehalten ist, die Drehfestigkeit und die Zugfestigkeit verstärkt werden.The basic idea of the invention is to be seen in that the torsional strength and the tensile strength are reinforced by the formation of longitudinal edges and at least one circumferential profiling at least in that anchor which is held in the masonry.

Aus Rationalisierungsgründen bietet sich an, auch denjenigen Anker entsprechend auszubilden, der sich im wesentlichen in der Dämmschicht befindet, auch wenn diese zur Aufnahme von hohen Zug- und Drehbeanspruchungen ungeeignet ist.For reasons of rationalization, it is also advisable to design those anchors which are essentially located in the insulating layer, even if they are unsuitable for absorbing high tensile and torsional stresses.

Durch Ausgestaltung des Dämmelementes als zylindrisches Bauteil mit beidseitig angebrachten Gewindeenden und korrespondierenden Gewindebohrungen in den Stirnenden der Anker lässt sich ein stabiler Verbund dieser Bauteile zu dem erfindungsgemäßen Abstandshalter herstellen, bei dem die beidseitig des Dämmelementes verlaufende Ringschulter als Anschlag für die Anker dienen kann.By designing the insulating element as a cylindrical member with threaded ends on both sides and corresponding threaded holes in the front ends of the armature, a stable composite of these components can be produced to the spacer according to the invention, in which the annular shoulder running on both sides of the insulating element can serve as a stop for the anchor.

Die zumindest eine am Umfang verlaufende Profilierung des in der tragenden Wandung sitzenden Ankers kann dabei auch als Ablängmarkierung dienen, um aus einem lagermäßig vorrätigen Anker bestimmter Baulänge einen Anker der im Hinblick auf das Mauerwerk und auch die Dämmschicht benötigten Baulänge herzustellen, so dass der Abstandshalter auf einfache Weise auch vor Ort an die baulichen Verhältnisse angepasst werden kann.The at least one circumferential profiling of the anchor sitting in the supporting wall can also serve as a Ablängmarkierung to produce from a stock in stock anchor of a certain length an anchor of the required in terms of the masonry and the insulating layer length, so that the spacer on simple way can also be adapted locally to the structural conditions.

Gemäß einer vorteilhaften Ausgestaltung ist vorgesehen, dass das Halteelement, für das der Abstandshalter dienen soll, ein Schraubkloben für einen Klappladen ist, dessen Aufnahmefläche für den Klappladen vertikal justierbar ist, so dass bauseits nicht immer zu vermeidende Toleranzen einander zugeordneten Abstandshalter, z.B. für die Halterung von beidseitig eines Fensters anzuordnenden Klappläden, auf einfache Weise ausgeglichen werden können.According to an advantageous embodiment, it is provided that the holding element for which the spacer is to serve, is a Schraubkloben for a folding shutter, the receiving surface for the folding shutter is vertically adjustable, so that on-site not always avoidable tolerances of associated spacers, e.g. for the holder of both sides of a window to be arranged shutters, can be compensated in a simple manner.

Weitere vorteilhafte Ausgestaltungen sind weiteren Unteransprüchen zu entnehmen.Further advantageous embodiments can be found in further subclaims.

Beschreibung des AusführungsbeispielsDescription of the embodiment

Der Abstandshalter besteht aus drei Bauteilen, nämlich einem in der tragenden Wand bzw. Mauerwerk W4 gehaltenen Anker 20, der als Sechskantanker ausgebildet ist und mehrere am Umfang verlaufende Profilierungen P aufweist. Die Querschnittsgestaltung des Sechskantankers erhöht wesentlich die Drehfestigkeit des Ankers im Mauerwerk bzw. in dem zum Kontakt mit dem Mauerwerk vorgesehenen Mörtel oder Klebstoff. Die Profilierungen P sind beim Ausführungsbeispiel als umlaufende Rillen ausgebildet, in die der Klebstoff bzw. Mörtel eindringen kann, was erheblich die Zugfestigkeit des Ankers in Richtung seiner Längsachse aus dem Mauerwerk heraus erhöht.The spacer consists of three components, namely a held in the load-bearing wall or masonry W4 anchor 20, which is designed as a hexagonal anchor and a plurality of circumferentially extending profiles P has. The cross-sectional configuration of the hexagonal anchor substantially increases the rotational strength of the anchor in the masonry or in the intended for contact with the masonry mortar or adhesive. The profiles P are formed in the embodiment as circumferential grooves into which the adhesive or mortar can penetrate, which significantly increases the tensile strength of the armature in the direction of its longitudinal axis out of the masonry out.

Zur Verbindung mit einem Dämmelement 30 weist der Anker 20 an seiner nach außen zeigenden Stirnseite eine Gewindebohrung 20A auf.For connection to an insulating element 30, the armature 20 has on its outwardly facing end face a threaded bore 20A.

Der zur Außenseite, zum Halteelement zeigende Abschnitt besteht ebenfalls aus einem Sechskantanker 10, dessen nach innen zeigende Stirnseite eine entsprechende Gewindebohrung 10A aufweist, und der an seinem nach außen zeigenden Ende eine weitere Gewindebohrung 10B aufweist, in die ein passendes Gewinde eines als Schraubkloben 40 ausgebildeten Halteelementes einschraubbar ist.The pointing to the outside, the holding member section also consists of a hexagonal anchor 10, the inwardly facing end side has a corresponding threaded bore 10A, and at its outwardly facing end has a further threaded bore 10B, into which a matching thread of a screw 40 formed as Retaining element is screwed.

Zur Verbindung der beiden Anker 10 und 20 dient das Dämmelement 30, das aus einem einstückig hergestellten Bauteil aus faserverstärktem Verbundwerkstoff besteht, mit einem Mittelabschnitt 30A und daran stirnseitig anschließenden Gewindeenden 30B,30C, die in die Gewindebohrungen 10A,20A der beiden Anker 10 und 20 passen. Das Mittelteil 30A hat einen größeren Durchmesser als die Gewindeenden 30B,30C, so dass am Übergang zwischen diesen Abschnitten umlaufende Randschultern R1,R2 gebildet werden, die als Anschlag für die beiden Anker 10,20 beim Aufschrauben auf das Dämmelement 30 dienen und den Abstandshalter zuverlässig gegen Verbiegungen stabilisieren.To connect the two anchors 10 and 20, the insulating element 30, which consists of an integrally made component made of fiber reinforced composite material, with a central portion 30A and front end subsequent threaded ends 30B, 30C, in the threaded holes 10A, 20A of the two anchors 10 and 20th fit. The central part 30A has a larger diameter than the threaded ends 30B, 30C, so that at the transition between these sections circumferential edge shoulders R1, R2 are formed, which serve as a stop for the two Anchor 10,20 serve when screwing on the insulating element 30 and reliably stabilize the spacer against bending.

in diesem montierten Zustand kann der Abstandshalter dann in die Wandung W eingebaut werden, wozu eine in Figur 2 schematisch dargestellte Siebhülse verwendet werden kann, dies ist aber nicht erforderlich, wie in Figur 3 dargestellt.in this assembled state, the spacer can then be installed in the wall W, including an in FIG. 2 shown sieve sleeve can be used, but this is not required, as in FIG. 3 shown.

In das nach außen zeigende Gewindeende des Ankers 10 ist ein Schraubkloben 40 als Halteelement einschraubbar, der einen Klappladen K schwenkbar aufnimmt.In the outwardly facing threaded end of the armature 10 is a Schraubkloben 40 can be screwed as a holding element which receives a folding shutter K pivotally.

Gemäß einer besonderen Ausgestaltung der Erfindung ist der Schraubkloben 40 so ausgebildet, dass seine Auflagefläche für den Klappladen K höhenverstellbar ist, so dass beispielsweise Toleranzen, die auf beiden Seiten eines Fensters beim Einbau der beiden Abstandshalter entstehen können, ausgeglichen werden können und ein passgenaues Schließen der beiden Klappladenhälften erreicht werden kann.According to a particular embodiment of the invention, the Schraubkloben 40 is formed so that its support surface for the folding shutter K is height adjustable, so that, for example, tolerances that can arise on both sides of a window during installation of the two spacers, can be compensated and a perfect fit of the two folding shutter halves can be achieved.

In bekannter Weise ist der Schraubkloben 40 zunächst aus einem hülsenförmigen Aufnahmeelement 41 aufgebaut. In dessen Innenraum ist ein Stellelement 42 vertikal verschiebbar, das sich nach oben einstückig in einen koaxial verlaufenden Haltezapfen 43 mit geringerem Durchmesser fortsetzt, so dass eine umlaufende Schulter S entsteht, auf die die Haltehülse des Klappladens aufsetzbar ist.In a known manner, the Schraubkloben 40 is first constructed of a sleeve-shaped receiving element 41. In the interior of an actuator 42 is vertically displaceable, which continues upward in one piece in a coaxially extending retaining pin 43 with a smaller diameter, so that a circumferential shoulder S is formed, to which the retaining sleeve of the folding shutter can be placed.

Beim dargestellten Ausführungsbeispiel weist das Aufnahmeelement 41 einen Aussenurchmesser von 19 mm und einen Innendurchmesser von 15 mm auf, der Haltezapfen 43 einen Durchmesser von 9 mm.In the illustrated embodiment, the receiving element 41 has an outer diameter of 19 mm and an inner diameter of 15 mm, the retaining pin 43 has a diameter of 9 mm.

Zur Einstellung der Höhe der Schulter S dient ein Stellstift 44, der durch den Boden 41 A des Aufnahmeelementes 41 verschiebbar geführt und mit dem Aufnahmeelement 41 fest verbunden ist. Durch Betätigung des Stellstiftes 44 lässt sich das Stellelement mit dem Haltezapfen 43 vertikal verschieben und dadurch die Vertikalposition des Klappladens K justieren.To adjust the height of the shoulder S is an adjusting pin 44 which is slidably guided by the bottom 41 A of the receiving element 41 and fixedly connected to the receiving element 41. By actuating the adjusting pin 44, the adjusting element can be moved vertically with the holding pin 43 and thereby adjust the vertical position of the folding shutter K.

Es ist auch möglich, den Haltezapfen 43 exzentrisch zum Stellelement 42 anzuordnen, wie dies in Figur 4 gestrichelt und schraffiert dargestellt ist. Bei dieser Variante besteht die Möglichkeit , durch Verdrehung des Stellelements 42 eine Horizontalverschiebung des Haltezapfens 43 zu erzielen, wodurch auch die Horizontalposition des Klappladens K relativ zur Wandung W justierbar wird.It is also possible to dispose the retaining pin 43 eccentrically to the adjusting element 42, as in FIG. 4 dashed and hatched is shown. In this variant, it is possible by rotation of the adjusting element 42 to achieve a horizontal displacement of the holding pin 43, whereby the horizontal position of the folding K is relative to the wall W adjustable.
