Abstract

The flat sheet wall anchor (18) terminates in end zones (24) to lie in a common plate (E) both sides of the centre zone (25). The zones (24) are adjoined by respective flat parts (28) of the centre zone which are twisted 180 deg. or 90 deg. round the centre line (M) traversing the longitudinal axis (A) of the anchor bolt, with both flats twisted round in the same direction. The centre zone is longer than the end zones which can also be twisted opposite ways, the length (q) of the deformable flat parts to amount to half that (e) of the end zones. Thus the surfaces (B) of the end zones lie flush with those of the anchor bolt and the longways edges (30,31) of the anchor as divided by the centre line are arranged on opposite sides of the axis. The free ends of the end zones go over into transverse arms (20) set at angles to the axis to end here in an angled flange part (22) directed towards the centre line. <IMAGE>

Description

Die Erfindung betrifft einen Maueranker zum Verbinden zweier einander in Abstand zugeordneter Bauelemente, insbesondere zweier Schalen einer Wand, mit -- gegebenenfalls aus der Längsachse des Mauerankers herausgeformten --Ankerenden und einer um diese Längsachse aus dem Werkstoff des Mauerankers -- mit diesem -- einstückig gedrehten Mittelzone.The invention relates to a wall anchor for connecting two mutually spaced components, in particular two shells of a wall, with - if necessary formed from the longitudinal axis of the wall anchor - anchor ends and one about this longitudinal axis from the material of the wall anchor - with this - in one piece turned central zone.

Ein Maueranker dieser Art ist der CH-PS 441 679 zu entnehmen, der zur Verbindung von gegeneinander beweglichen Bauelementen geeignet sein soll. Dieser vorbekannte Federanker ist einstückig aus einem Rundstahl hergestellt und mit einer schraubenfederartigen Mittelzone ausgestattet, von der beidseits achsparallel Drahtarme abragen, welche jeweils endwärts teilkreisförmig gekrümmt sind. Die CH-PS 441 679 erwähnt auch andere Federelemente wie zickzackförmig gebogene Federdrähte, Federn aus natürlichem oder synthetischem Kautschuk, Luftfedern od.dgl. mehr. Als bevorzugter Werkstoff wird ein Draht aus Federstahl erwähnt, beispielsweise aus Chrom-Nickel-Stahl 18/8. Hervorgehoben wird auch der Wunsch nach Korrosionsbeständigkeit des Federankers.A wall anchor of this type can be found in CH-PS 441 679, which should be suitable for connecting mutually movable components. This previously known spring anchor is made in one piece from a round steel and is equipped with a helical spring-like central zone, from which wire arms project on both sides, axially parallel, which are each curved at the end in a partially circular manner. The CH-PS 441 679 also mentions other spring elements such as zigzag bent spring wires, springs made of natural or synthetic rubber, air springs or the like. more. A wire made of spring steel is mentioned as the preferred material, for example made of chrome-nickel steel 18/8. The desire for corrosion resistance of the spring anchor is also emphasized.

In Kenntnis dieses Standes der Technik hat sich der Erfinder das Ziel gesetzt, einen Maueranker insbesondere für mehrschalige Wände zu schaffen, welcher auf einfachere Weise als eine Schraubenfeder herzustellen ist und ausreichende Festigkeitswerte anbietet.Knowing this state of the art, the inventor has set itself the goal of creating a wall anchor, in particular for multi-layer walls, which is easier to produce than a coil spring and offers sufficient strength values.

Zur Lösung dieser Aufgabe führt die Lehre des unabhängigen Anspruches; die Unteransprüche geben günstige Weiterbildungen an.The teaching of the independent claim leads to the solution of this task; the subclaims indicate favorable further training.

Erfindungsgemäß weist der aus einem Flachstahl geformte Maueranker beidseits der Mittelzone miteinander etwa in einer Ebene fluchtende Endzonen des Flachstahls auf, an welche jeweils ein Flachstahlabschnitt der Mittelzone anschließt, welcher etwa bis zu deren die Längsachse querenden Mittellinie hin ca. 180° um die Längsachse gedreht ist; die beiden Flachstahlabschnitte der Mittelzone sind in einer gemeinsamen Drehrichtung gedreht.According to the invention, the wall anchor formed from a flat steel on both sides of the central zone has end zones of the flat steel which are aligned with one another approximately in one plane, to each of which a flat steel section of the central zone adjoins, which is rotated approximately 180 ° about the longitudinal axis up to the central line crossing the longitudinal axis ; the two flat steel sections of the central zone are rotated in a common direction of rotation.

Nach einem weiteren Merkmal der Erfindung fluchtet etwa mit den Oberflächen der Endzonen des Mauerankers in der Mittellinie der Gegenfläche des Flachstahles, d.h. von jedem der Endzonen bis zur Mittellinie ist das Bandmaterial in einer einzigen Steigung gedreht - die andere Steigung schließt dann gegensinnig an.According to a further feature of the invention is approximately aligned with the surfaces of the end zones of the wall anchor in the center line of the counter surface of the flat steel, i.e. from each of the end zones to the center line, the strip material is turned in a single pitch - the other pitch then connects in opposite directions.

Vorteilhafterweise liegen die von der Mittellinie geschnittenen Längskanten des von der Mittellinie aus gedrehten Mauerankers in dessen Endzonen an der jeweils anderen Seite der Längsachse.Advantageously, the longitudinal edges cut by the center line of the wall anchor turned from the center line lie in its end zones on the other side of the longitudinal axis.

Bei einer weiteren Ausgestaltung des Mauerankers schließt an jede der fluchtenden Endzonen ein Verformungsabschnitt an, wobei Verformungsabschnitte einen ebenen Bereich der Mittelzone begrenzen, zu dem die beiden Endzonen auch hie etwa 180° um die Längsachse in einer gemeinsamen Drehrichtung gedreht sind.In a further embodiment of the wall anchor, a deformation section adjoins each of the aligned end zones, deformation sections delimiting a flat region of the central zone, to which the two end zones are also rotated about 180 ° about the longitudinal axis in a common direction of rotation.

Dank dieser Maßgaben entsteht ein zu jener Mittellinie hin beidseits gleichsinnig gedrehter Formkörper, der die der Erfindung zugrunde liegende Aufgabe in bestechender Weise erfüllt. Wenn im übrigen vorstehend und nachfolgend von einem Flachstahl die Rede ist, so soll dieser Begriff jede Art von Bandmaterial erfassen, also auch Streifen aus einer Aluminiumlegierung oder einem Kunststoff mit Eigenschaften, die jenen metallischer Werkstoffe entsprechen.Thanks to these provisions, a molded body is produced which is rotated in the same direction on both sides of the center line and which fulfills the object on which the invention is based in an impressive manner. If, above and below, there is talk of flat steel, this term is intended to encompass any type of strip material, that is to say also strips of an aluminum alloy or a plastic with properties which correspond to those of metallic materials.

Im Rahmen der Erfindung liegt auch ein aus einem Flachstahl geformter Maueranker mit beidseits der Mittelzone miteinander in einer Ebene fluchtenden Endzonen, die um die Längsachse des Mauerankers gegen die Mittelzone um 90° gedreht sind, dies entweder -- wie oben beschrieben --gleichsinnig oder auch gegensinnig um die Längsachse gedreht.Within the scope of the invention there is also a wall anchor formed from a flat steel with end zones aligned on both sides of the central zone in one plane, which are rotated by 90 ° about the longitudinal axis of the wall anchor against the central zone, either in the same direction or as described above rotated in opposite directions around the longitudinal axis.

Zur besseren Verankerung der freien Enden der Endzonen können diese in aus der Längsachse heraus gewinkelte Querarme übergehen, die bevorzugt jeweils endwärts mit einem aus ihrer Ebene herausgeformten Formsteg ausgestattet sind. Die Formstege der Querarme weisen vorteilhaft zueinander und bilden so Widerhaken im Mauerwerk.For better anchoring of the free ends of the end zones, these can merge into transverse arms angled out of the longitudinal axis, each of which is preferably provided at the end with a shaped web shaped out of its plane. The shaped webs of the cross arms advantageously face each other and thus form barbs in the masonry.

Bei einem weiteren Ausführungsbeispiel des Erfindungsgegenstandes ist ein Teil der einen Endzone des Mauerankers abgetrennt und durch einen axialen Gewindestift ersetzt, der durch Umbördeln und Verschweißen oder Verkleben am Maueranker festliegt und in eine Schraubbüchse od.dgl. Gegenorgan des Mauerwerkes eingeschraubt zu werden vermag.In a further embodiment of the subject of the invention, part of one end zone of the wall anchor is separated and replaced by an axial threaded pin which is fixed to the wall anchor by flanging and welding or gluing and into a screw sleeve or the like. Opposing organ of the masonry can be screwed in.

Auch liegt es im Rahmen der Erfindung eine der Endzone ohne Querarme herzustellen und stattderen mit reibungserhöhenden Ein- und/oder Ausformungen der Flachstahlflächen zu versehen; diese können dann formschlüssig im Mauerwerk festgelegt sein.It is also within the scope of the invention to manufacture one of the end zones without transverse arms and instead to provide them with friction-increasing molding and / or shaping of the flat steel surfaces; these can then be positively fixed in the masonry.

Bei der Herstellung der Maueranker wird erfindungsgemäß ein stegartiger Flachstahlrohling etwa in Längsmitte eingespannt, wonach die beidseits abstehenden Rohlingshälften in der Längsachse des Flachstahlrohlings um jene erwähnten 180° gleichsinnig oder um etwa 90° gedreht werden.In the manufacture of the wall anchors, according to the invention, a web-like flat steel blank is clamped approximately in the longitudinal center, after which the blank halves which protrude on both sides are rotated in the same direction or about 90 ° in the longitudinal axis of the flat steel blank.

In Fig. 1 ist innerhalb einer zweischaligen Wand 10 aus einer Außenschale 12, einer Innenmauerung 14 sowie einem --in einem von beiden Schalen 12, 14 begrenzten Spalt 13 der Breite a vorgesehenen -- Isolierkern 16 ein Maueranker 18 aus einem Flachstahl der beispielsweisen Breite b von 14 mm und einer Dicke i von etwa 2 mm festgelegt.In Fig. 1, a wall anchor 18 made of a flat steel of the example width is within a double-shell wall 10 of an outer shell 12, an inner wall 14 and an insulating core 16 - provided in a gap 13 of width a limited by two shells 12, 14 b of 14 mm and a thickness i of about 2 mm.

An den beiden in die Außenschale 12 bzw. die Innenmauerung 14 eingreifenden Ankerenden sind etwa rechtwinklig zur Längsachse A des Mauerankers 18 verlaufende Querarme 20 aus dem Flachstahl bzw. Bandmetall herausgeformt und können ihrerseits endwärts mit zur Mittellinie M des Mauerankers 18 weisenden Formstegen 22 versehen sein.On the two anchor ends engaging in the outer shell 12 and the inner wall 14, transverse arms 20 extending approximately at right angles to the longitudinal axis A of the wall anchor 18 are formed from the flat steel or strip metal and can in turn be provided with molding webs 22 pointing towards the center line M of the wall anchor 18.

Der Maueranker 18 einer Gesamtlänge n von beispielsweise 240 mm ist in Fig. 2, 3 in drei Zonen 24, 25, 24 etwa gleicher Zonenlänge e unterteilt; die beiden äußeren Endzonen 24 -- von denen die Oberfläche B der einen Endzone 24 in Fig. 2, links, schraffiert hervorgehoben ist -- gehen jeweils von den Querarmen 20 aus und verlaufen in der in Fig. 3, 4 angedeuteten Flachstahlebene E, aus der beispielsweise jene Querarme 20 um 90° unter Bildung einer Stirneinformung 26 herausgedreht sind. Die Stirneinformung 26 wird in Längsachse A durch eine bauchähnliche Ausformung 27 begrenzt, die beispielhaft in Fig. 3, links, zu erkennen ist.The wall anchor 18 with a total length n of, for example, 240 mm is divided into three zones 24, 25, 24 of approximately the same zone length e in FIGS. 2, 3; the two outer end zones 24 - of which the surface B of the one end zone 24 is hatched in FIG. 2, on the left - each extend from the transverse arms 20 and extend in the flat steel plane E indicated in FIGS. 3, 4 which, for example, those transverse arms 20 are turned out by 90 ° to form a front indentation 26. The front molding 26 is delimited in the longitudinal axis A by a bulge-like molding 27, which can be seen by way of example in FIG. 3, left.

Die Mittelzone 25 des Mauerankers 18 ist so verformt, daß gemäß Fig. 2 bis 4 in der eine Symmetriegerade darstellenden Mittellinie M die Oberfläche B -- gewendet -- in Gegenrichtung weist und dort die Gegenfläche Q des Mauerankers 18 sichtbar wird; zwischen den Enden -- Linie N in Fig. 2 -- der beiden Außenzonen 24 und der Mittellinie M ist der Flachstahl jeweils um 180° gedreht.The central zone 25 of the wall anchor 18 is deformed such that, according to FIGS. 2 to 4, in the center line M representing a line of symmetry, the surface B - turned - points in the opposite direction and the counter surface Q of the wall anchor 18 is visible there; between the ends - line N in FIG. 2 - of the two outer zones 24 and the center line M, the flat steel is rotated in each case by 180 °.

Der Maueranker 18 erhält seine beschriebene Form dadurch, daß der -- aus Gründen der Übersichtlichkeit nicht dargestellte -- Flachstahlrohling in der Mittellinie M in einem in Fig. 2 durch Begrenzungslinien G kenntlich gemachten Bereich eingespannt wird, wonach die beidseits abstehenden Rohlingshälften gleichsinnig (Pfeile x in Fig. 3) in der Längsachse A um jene 180° gedreht werden. Jene beiden Linien N begrenzen jeweils einen Verformungsabschnitt oder Drehungsbereich 28 einer Länge q nach außen, der zur Mittellinie M hin an der Begrenzungslinie G endet.The wall anchor 18 is given its shape as described in that the flat steel blank (not shown for reasons of clarity) is clamped in the center line M in an area identified by boundary lines G in FIG. 2, after which the blank halves projecting on both sides are in the same direction (arrows x in Fig. 3) are rotated in the longitudinal axis A by that 180 °. Those two lines N each delimit a deformation section or rotation region 28 of length q to the outside, which ends at the boundary line G towards the center line M.

Der Maueranker 18a in Fig. 5 ist etwa in der in Fig. 4, unten, angedeuteten Schnittstelle unter Bildung einer Endkante 29 abgelängt und mit einem axialen Gewindebolzen 33 für eine -- nicht wiedergegebene -- in einer Wand festliegende Gewindebüchse od.dgl. Gegenelement ausgestattet; der Gewindebolzen 33 wird in einen gebördelten Flachstahlabschnitt eingeschweißt bzw. eingeklebt. Die Längskanten 30, 31 des Flachstahles bzw. Mauerankers 18a liegen dabei in einer gemeinsamen Ebene.The wall anchor 18 a in FIG. 5 is cut to length in the interface indicated in FIG. 4, below, forming an end edge 29 and with an axial threaded bolt 33 for a threaded bushing or the like which is not shown in a wall and is not shown. Counter element equipped; the threaded bolt 33 is welded or glued into a flanged flat steel section. The longitudinal edges 30, 31 of the flat steel or wall anchor 18 a lie in a common plane.

Der Maueranker 18b der Fig. 6 bietet statt des Gewindebolzens 33 ein querschnittlich rinnenähnlich gekrümmtes Endstück 34 mit widerhakenartigen Retentionen 36 an.The wall anchor 18 b of FIG. 6 has, instead of the threaded bolt 33, a cross-sectionally channel-like curved end piece 34 with barb-like retainers 36 at.

Die Länge e₁ der Mittelzone 25a zwischen den Linien N ist beim federnden Maueranker 18c der Fig. 7, 8 -- aus einem Bandmetall V4A 15 x 1,5 mm -- größer als die Länge e der Endzonen 24, was ebenfalls für den Abstand f der Begrenzungslinie G voneinander im Vergleich mit Fig. 2 zutrifft. Auch hier sind beide Endzonen 24 gleichsinnig gedreht, dies jeweils in einem Winkel von 90°.The length e 1 of the central zone 25 a between the lines N is in the resilient wall anchor 18 c of Fig. 7, 8 - from a band metal V4A 15 x 1.5 mm - greater than the length e of the end zones 24, which is also for the Distance f of the boundary line G from one another in comparison with FIG. 2 applies. Here, too, both end zones 24 are rotated in the same direction, each at an angle of 90 °.

Die Drehung des Mauerankers 18d der Fig. 9, 10 mißt auch 90° -- jedoch bei gegensinniger Drehung -- mit der Folge, daß die Oberfläche B der einen Endzone 4 mit der Gegenfläche Q der anderen Endzone 24 fluchtet. Hier sind die drei Zonen 24, 25, 24 wieder von etwa gleicher Länge e.The rotation of the wall anchor 18 d of FIGS. 9, 10 also measures 90 ° - but with opposite rotation - with the result that the surface B of one end zone 4 is aligned with the counter surface Q of the other end zone 24. Here are the three zones 24, 25, 24 again of approximately the same length e.

Der Maueranker 18e der Fig. 11, 12 ist beidseits der Mittelzone 25a der Länge e₁ gleichsinnig jeweils um 180° gedreht; die Oberflächen B beider Endzonen 24 fluchten mit der Gegenfläche Q der Mittelzone 25a, die hier verhältnismäßig langflächig ist.The wall anchor 18 e of Figures 11, 12 is rotated on both sides of the central zone 25 a of length e 1 in the same direction by 180 °; the surfaces B of the two end zones 24 are flush with the counter surface Q of the central zone 25 a , which is relatively long in this case.

Wie Fig. 12 deutlich werden läßt, sind die bei der Drehung entstehenden Verformungsabschnitte 28 sehr kurz; deren Länge q entspricht etwa der halben Länge e des ebenen Teiles der Mittelzone 25a und damit auch der halben Länge e einer Endzone 24.As can be seen in FIG. 12, the deformation sections 28 which arise during the rotation are very short; whose length q corresponds to approximately half the length e of the flat part of the central zone 25 a and thus also half the length e of an end zone 24.
