Description

Die Erfindung bezieht sich auf einen als schmalen Streifen ausgebildeten Flachstahlanker für Mauerwerk, der an beiden Enden mehrere hintereinander angeordnete, über die Ankerlänge verteilte, flach gehaltene Einsenkungen aufweist.The invention relates to a narrow strip trained flat steel anchors for masonry, on both Ends several in a row, over the Anchor length distributed, flat depressions having.

Dieser Flachstahlanker befinden sich flach liegend zwischen den Steinen des Mauerwerks, das aus beliebigen Steinen z.B. aus Kalksandsteinen, Gasbeton-Steinen oder ähnlichen Steinen besteht. Dabei sind die Flachstahlanker in den Fugen des Mauerwerks in dem dort befindlichen Mörtel oder Bindemittel angeordnet, und zwar vorzugsweise im Stossbereich des Mauerwerks. Da die Flachstahlanker vorwiegend auf Zug beansprucht werden, ist es wichtig, dass die Enden des Flachstahlankers gut fixiert sind, also über eine gute Ausreissfestigkeit verfügen.These flat steel anchors are located flat between the stones of the masonry, which can be made from any stones e.g. made of sand-lime bricks, gas-concrete blocks or the like Stones. The flat steel anchors are in the Grouting the masonry in the mortar or there Binder arranged, preferably in Joint area of the masonry. Because the flat steel anchors predominantly train, it is important that the ends of the flat steel anchor are well fixed, i.e. over have good pull-out strength.

Bei den bekannten Flachstahlankern dieser Ausbildung ( GB-A-2143554 ) sind die an den Ankerenden befindlichen, zur Aufnahme von Mörtel geeigneten Einsenkungen - bei Betrachtung des Ankers im Grundriss - rechteckig gestaltet. Ferner sind Luftschichtanker für Mauerwerk bekannt (GB-A-21900938 ), die an einem Ende flach und am anderen Ende stabförmig gestaltet sind sowie im Bereich ihres flachen-Endes mehrere, in Ankerlängsrichtung hintereinander angeordnete Einsenkungen mit rundem Grundriss aufweisen.In the known flat steel anchors of this design (GB-A-2143554 ) are those at the anchor ends, for Inclusion of mortar suitable depressions - at Viewing the anchor in the floor plan - rectangular. Air layer anchors for masonry are also known (GB-A-21900938 ) that are flat at one end and at the other end are rod-shaped and in the area of their flat end several, one behind the other in the longitudinal direction of the anchor have arranged depressions with a round floor plan.

Der aus der GB-A-2143554 bekannte Flachstahlanker weist die Merkmale des Oberbegriffes des Anspruchs 1 auf.The flat steel anchor known from GB-A-2143554 has the features of the preamble of claim 1.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs erwähnten Flachstahlanker so auszubilden, dass sie eine grosse Ausreissfestigkeit und zudem bei kleiner Wandstärke einen grossen aktiven Querschnitt über ihre Länge hinweg in der Weise verfügen, dass der Flachstahlanker eine vergleichsweise grosse Zugfestigkeit aufweist. Mit geringem Materialaufwand soll ein zug- und ausreisfester Flachstahlanker geschaffen werden.The invention is based on the object at the outset mentioned flat steel anchors so that they have a great pull-out strength and also with small wall thickness a large active cross section along its length in the way that the flat steel anchor a has comparatively high tensile strength. With little Material expenditure should be more resistant to pulling and leaving Flat steel anchors are created.

Zur Lösung dieser Aufgabe wird für Flachstahlanker der eingangs erwähnten Ausbildung erfindungsgemäss vorgeschlagen, daß die Einsenkungen an beiden Enden des Flachstahlankers, hintereinander angeordnet, über die Ankerlänge verteilt und keilförmig, sich in Richtung der Belastung des Flachstahlankers verjüngend gestaltet sind, so dass die Verjüngung der an beiden Ankerenden befindlichen Einsenkungen in Richtung auf das Mittelstück des Flachstahlankers zeigt. Diese Einsenkungen bilden Vorsprünge bzw. Vertiefungen, um so einen Formschluss mit dem in den Fugen des Mauerwerks befindlichen Bindemittel eingehen zu können.To solve this task, for flat steel anchors proposed training according to the invention, that the depressions at both ends of the flat steel anchor, arranged one behind the other, distributed over the anchor length and wedge-shaped, towards the load of the flat steel anchor are tapered, so that the taper of those located at both anchor ends Depressions towards the middle section of the flat steel anchor shows. These depressions form protrusions or depressions, so a form fit with that in the joints of the masonry existing binders to be able to enter.

Die Einsenkungen stellen sicher, dass der aktive Querschnitt des Ankers erhalten bleibt und zu keiner Verringerung der Zugfestigkeit des Flachstahlankers führen köännen. Vorzugsweise wird nur eine Reihe dieser Einsenkungen vorgesehen, sodass über die Breite des Ankers gesehen nicht zwei oder drei Einsenkungen, sondern nur eine Einsenkung vorhanden ist, wenngleich die Erfindung auch zwei oder weitere nebeneinander angeordnete Einsenkungen in besonderen Fällen vorsehen kann. Darüber hinaus können die Einsenkungen auch mit kleinen Löchern versehen sein, um bei der Montage Lufteinschlüsse oder dgl. auszuschliessen. The depressions ensure that the active Cross-section of the anchor remains and none Reduce the tensile strength of the flat steel anchor can. Preferably only a number of these Depressions provided so that across the width of the anchor not seen two or three depressions, but only a depression is present, although the invention also two or more arranged side by side Can provide for reductions in special cases. About that the depressions can also be made with small holes be provided to avoid air pockets or the like during assembly. to exclude.

Eine weitere Steigerung der Fixierung dse Ankers kann dadurch erreicht werden, dass die in einer Reihe hintereinander, auf der Längsmittelachse des Flachstahlankers vorgesehenen Einsenkungen wechselseitig angeordnet werden, so dass eine Einsenkung auf der einen Seite des Flachstahlankers einer Einsenkung auf der anderen Seite des Flchstahlankers folgt.A further increase in the fixation of this anchor can can be achieved in that in a row in a row, on the longitudinal central axis of the Flat steel anchors provided recesses alternately be arranged so that a depression on one Side of the flat steel anchor one depression on the other Side of the flat steel anchor follows.

Der Flachstahlanker kann seitlich von zwei einander parallelen geraden Kanten begrenzt sein. Vorzugsweise erhalten die seitlichen Kanten aber eine Gestaltung, die zur Erhöhung der Ausreissfestigkeit des Ankers beiträgt. Besonders zweckmässig ist es dabei, wenn der Flachstahlanker insgesamt über seine gesamte Länge hinweg einen wellen- oder zickzackförmigen Grundriss aufweist in der Weise, sich Vertiefungen auf der einen Seite des Flachstahlankers einem Vorsprung auf der anderen Ankerseite gegenüberliegen, wobei die Grösse der Vertiefung bzw. eines Vorsprungs etwa ein Zehntel bis ein Sechstel der Breite des Flachstahlankers beträgt.The flat steel anchor can laterally from two parallel straight edges parallel to each other. However, the side edges are preferably given one Design to increase the pull-out strength of the Anchor contributes. It is particularly useful if the flat steel anchor as a whole over its entire length a wavy or zigzag-shaped floor plan has depressions in one way One side of the flat steel anchor on the other Anchor side opposite, the size of the recess or a lead about a tenth to a sixth of the Flat steel anchor width.

Weitere Einzelheiten der Erfindung werden anhand der Zeichnung erläutert, in der ein Ausführungsbeispiel der Erfindung dargestellt ist. Es zeigen :

  • Fig. 1 eine Stossverbindung eines aus Formsteinen gebildeten Mauerwerks in der Ansicht,
  • Fig. 2 die Stossverbindung nach Fig. 1 im Grundriss,
  • Fig. 3 einen Schnitt nach der Linie III - III von Fig. 2,
  • Fig. 4 einen Flachstahlanker für die Verwendung gemäss Fig. 1 - 3 im Grundriss,
  • Fig. 5 ein Ende des Ankers gemäss Fig. 4 im vergrösserten Masstab und
  • Fig. 6 einen Schnitt nach der Linie VI - VI von Fig. 5.
    • Further details of the invention will be explained with reference to the drawing, in which an embodiment of the invention is shown. Show it :
  • 1 is a butt joint of a masonry formed from shaped stones in the view,
  • 2 shows the butt joint according to FIG. 1 in plan view,
  • 3 shows a section along the line III - III of FIG. 2,
  • 4 shows a flat steel anchor for use according to FIGS. 1-3 in the plan,
  • 5 an end of the armature according to FIG. 4 on an enlarged scale and
  • 6 shows a section along the line VI - VI of FIG. 5.

    • Das z.B. aus Kalksandsteinen 1 bestehende Mauerwerk hat eine längs verlaufende Wand 2 und eine Querwand 3; die vergrössert dargestellten Fugen 4 sind mit einem Binde- oder Klebemittel gefüllt. In einer waagerechten Fuge 4 ist ein Flachstahlanker 5 angeordnet, der als schmaler Sreifen ausgeführt ist, aus Edelstahl besteht und mit seiner einen Hälfte in der Wand 2 und mit der anderen Hälfte in der Querwand 3 angeordnet ist, um so die gegenseitige Verankerung der beiden Wände zu bewirken.That e.g. has 1 existing masonry made of sand-lime bricks a longitudinal wall 2 and a transverse wall 3; the Grooves 4 shown enlarged are with a binding or Filled with adhesive. In a horizontal joint 4 is a flat steel anchor 5 arranged as a narrow tire is made of stainless steel and with one Half in the wall 2 and the other half in the Transverse wall 3 is arranged so as to mutual To anchor the two walls.

    Der Flachstahlanker 5 hat gemäss Fig. 4 eine Gesamtlänge von L = 270 mm und gemäss Fig. 6 eine Wandstärke s = 0.5 mm. Er weist flache Einsenkungen 6 auf, die in einer Reihe symmetrisch in Bezug auf die Längsmittelachse 7 angeordnet und eine Tiefe t haben, die dem Mass s entspricht, also 0.5 mm beträgt. Diese Einsenkungen 6 werden durch Pressdruck und bleibende Verformungen des Werkstoffes erreicht. Wie aus Fig. 6 erkennbar ist, sind die Einsenkungen 6 abwechselnd nach oben und unten, also wechselseitig eingepresst, um so am Flachstahlanker oben und unten kleine flache Vorsprünge zu erreichen, um die Ausreissfestigkeit bei Beanspruchungen in Richtung der beiden Pfeile 8 zu erhöhen.The flat steel anchor 5 has an overall length according to FIG. 4 of L = 270 mm and according to FIG. 6 a wall thickness s = 0.5 mm. It has shallow depressions 6 in a row arranged symmetrically with respect to the longitudinal central axis 7 and have a depth t that corresponds to the dimension s, i.e. 0.5 mm. These depressions 6 are by pressing and permanent deformation of the material is achieved. How 6 shows the depressions 6 alternating upwards and downwards, i.e. alternately pressed in, so small on the flat steel anchor above and below to achieve flat protrusions to ensure the pull-out strength for stresses in the direction of the two arrows 8 increase.

    Aus diesen Gründen sind auch die Einsenkungen 6 in Richtung der Beanspruchung keilförmig sich verjüngend ausgeführt; die Spitzen 9 der Einsenkungen 6 zeigen also auf das Mittelstück des Flachstahlankers 5, das eine etwa quadratische Einsenkung 6' aufweist, deren gegenüberliegende Spitzen 10 auf die Enden des Flachstahlankers 5 zeigen. Die Einsenkungen 6 zu beiden Seiten der Einsenkung 6' haben eine etwa dreieckigen Grundriss unter den oben genannten Bedingungen mit einer Spitzenrundung r = 2 - 3 mm, einer Breite b = 13 mm und einer Länge D = 17 mm. Von einer Basis zur Basis der folgenden Einsenkung 6 beträgt die Entfernung z = 23,5 mm. Im Mittelstück beträgt der Basisabstand b = 63 mm. Die symmetrisch in Bezug auf die Längsmittellinie 7 angeordneten Dreiecke bzw. Einsenkungen 6 haben einen Öffnungswinkel a = 40°.For these reasons, the depressions 6 are also in the direction the stress is tapered; the tips 9 of the depressions 6 thus point to that Center piece of the flat steel anchor 5, the one about has square depression 6 ', the opposite tips 10 on the ends of the Flat steel anchor 5 show. The depressions 6 to both The sides of the depression 6 'have an approximately triangular shape Floor plan under the above conditions with a Tip rounding r = 2 - 3 mm, a width b = 13 mm and a length D = 17 mm. From a base to the base of the following depression 6, the distance is z = 23.5 mm. The base distance in the center piece is b = 63 mm. The symmetrical with respect to the longitudinal center line 7 arranged triangles or depressions 6 have a Opening angle a = 40 °.

    Zur weiteren Steigerung bei Beanspruchung auf Zug in Richtung der Pfeile 8 ist eine besondere Kantengestaltung der seitlichen Kanten 11 des Flachstahlankers 6 vorgesehen. Insgesamt gesehen hat der Flachstahlanker 5 einen zickzackförmigen Grundriss, wobei die einzelnen Schenkel der Zickzackgestalt je eine Abmessung S = 27 mm aufweisen. Zwei aufeinanderfolgende Schenkel haben dann die Länge 2S = 54 mm. To further increase the strain on train in Direction of arrows 8 is a special edge design the lateral edges 11 of the flat steel anchor 6 are provided. Seen overall, the flat steel anchor 5 has one zigzag-shaped floor plan, the individual legs the zigzag shape each have a dimension S = 27 mm. Two consecutive legs then have the length 2S = 54 mm.

    Die durch die Zickzackform bedingten Vorsprünge 12 bzw. Einbuchtungen 13 auf der gegenüberliegenden Seite haben ein Mass von V = 3 mm. Dadurch ergeben sich Breitenmasse gemäss Fig. 4 unten. Die seitlichen Ausschläge bzw. Vorsprünge 12 sind zwar vergleichsweise klein, sie sind aber gerade so gross, dass eine ausreichend grosse Fixierung im Bindemittel des Mauerwerks stattfinden kann.The projections 12 or due to the zigzag shape Indentations 13 on the opposite side have one Dimension of V = 3 mm. This results in widths according to Fig. 4 below. The lateral deflections or projections 12 are comparatively small, but they are just that large that a sufficiently large fixation in the Masonry binders can take place.

    Die hier angeführten Masse sind beispielhaft und geeignet, gebrauchstüchtige Anker zu erstellen. Es versteht sich, dass Abweichungen möglich sind z.B. im Hinblick auf die benutzen Bindemittel bzw. Mörtel und/oder die erforderlichen Festigkeiten der Flachstahlanker 5.The dimensions listed here are exemplary and suitable to create usable anchors. It goes without saying that deviations are possible e.g. in terms of use binders or mortar and / or required strength of the flat steel anchor 5.

    Bei der Montage und der Erstellung des Mauerwerks kann es sinnvoll sein, im Bereich der Einsenkungen 6 kleine Löcher 14 vorzusehen. Diese sollen jedoch vergleichsweise kleine Durchmesser erhalten, um so den aktiven Querschnitt des Ankers bei Belastung in Richtung der Pfeile 8 nicht nennenswert zu verringern.When assembling and creating the masonry it can 6 small holes make sense in the area of the depressions 14 to provide. However, these are said to be comparatively small Obtained diameter so that the active cross section of the Anchor not under load in the direction of arrows 8 to reduce significantly.

    Wichtig ist ferner, dass beiden Enden bzw. die beiden Hälften des Flachstahlankers im obigen Sinne mit Einsenkungen 6 bzw. Kantenprofilierungen versehen sind. Die mittig auf halber Länge angeordnete Einsenkung 6' mit abweichender Grundrissgestaltung ermöglicht zudem einen genauen symmetrischen Einbau z. B. in den Wänden 2, 3.It is also important that both ends or the two Halves of the flat steel anchor in the above sense Depressions 6 or edge profiles are provided. The depression 6 'arranged in the middle of half the length deviating floor plan design also allows one exact symmetrical installation z. B. in the walls 2, 3.

    Aus der Zeichnung ist im übrigen ersichtlich, dass jedem Schenkel der Zickzackform eine Einsenkung 6 zugeordnet ist.From the drawing it can be seen that everyone Leg of the zigzag shape is assigned a depression 6.

    Ferner sei erwähnt, dass anstelle der zickzackförmigen Ränder 11 ggfs. auch abgewandelte Randformen benutzt werden können z.B. wellenförmige bzw. sinusartige Gestaltungen, wenngleich die dargestellte Zickzackform wegen der Herstellung Vorteile bringt.It should also be mentioned that instead of the zigzag Edges 11, if necessary, also modified edge shapes can be used can e.g. wavy or sinusoidal designs, although the zigzag shape shown because of the Manufacturing brings advantages.

    Wie aus Fig. 5 besonders gut zu entnehmen ist, kommen auf einen von einer Vertiefung 13 bzw. einem Vorsprung 12 gebildeten Längenabschnitt des Flachstahlankers 5 mit der Länge 2S zwei Einsenkungen 6.As can be seen particularly well from FIG. 5, come up one of a recess 13 or a projection 12 formed length section of the flat steel anchor 5 with the Length 2S two depressions 6.

    Es ist auch vorteilhaft, wenn die halben Längen des Flachstahlankers 5 je drei bis sieben, vorzugsweise aber - wie dargestellt - fünf Einsenkungenn 6 erhalten, die vorzugsweise in der Reihe mit einem gegenseitigen Abstand angeordnet werden, der im wesentlichen der halben Länge der Einsenkungen 6 entsprechen soll. Im übrigen ist es zweckmässig, die Grösse der Vertiefungen 13 bzw. der Vorsprünge 12 so auszuwählen, dass sie ein Zehntel bis ein Sechstel der Breite des Flachstahlankers 5 beträgt. Ein Mass von etwa 3 mm ist beonders vorteilhaft.It is also advantageous if half the lengths of the Flat steel anchor 5 each three to seven, but preferably - as shown - receive five depressions 6 that preferably in a row at a mutual distance be arranged which is substantially half the length of the Reductions 6 should correspond. Otherwise it is expedient, the size of the recesses 13 and Select projections 12 so that they are one tenth to one Sixths the width of the flat steel anchor 5. A Dimension of about 3 mm is particularly advantageous.

    Es sei weiterhin erwähnt, dass vorzugsweise die Einsenkungen - wie in der Zeichnung dargestellt - örtlich auf dem Anker, und zwar vorzugsweise symmetrisch anzuordnen sind. Gegebenenfalls können sich die Einsenkungen aber auch über die gesamte Breite des Ankers erstrecken ( wie z.B. in Fig. 6 schraffiert dargestellt ), gleichwohl sind aber auch die örtlichen und die letzterwähnten Einsenkungen in Kombination möglich.It should also be mentioned that preferably the Indentations - as shown in the drawing - locally on the anchor, preferably symmetrically are. If necessary, the depressions can also extend across the entire width of the anchor (e.g. in 6 hatched), but are also the local and the latter depressions in Combination possible.
