Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines aus einem dünnwandigen Material, vorzugsweise Stahl, bestehenden Luftschichtankers für Mauerwerk, wobei der Luftschichtanker an einem Ende flach gestaltet ist und einen anderen, das Übrige des Luftschichtankers bildenden stabförmigen Abschnitt aufweist, der durch Verformung des Ankerwerkstoffes gebildet ist. Die Erfindung bezieht sich ferner auf einen nach diesem Verfahren hergestellten Luftschichtanker.The invention relates to a method for manufacturing one of a thin-walled material, preferably Steel, existing air layer anchor for masonry, with the air layer anchor flat at one end is designed and another, the rest of the Air-layer anchor forming rod-shaped section has by the deformation of the anchor material is formed. The invention further relates to one made by this method Air layer anchor.

Derartige Luftschichtanker dienen der Verbindung von zweischaligem Mauerwerk z.B. der Verbindung einer Schale aus Kalksandstein bzw. Porenbeton einerseits und einer anderer, aussen gelegenen Mauerwerkschale andererseits, wobei in der Luftschicht zwischen diesen beiden Schalen Dämmplatten angeordnet sein können, die von dem in der Luftschicht angeordneten stabförmigen Längenabschnitt des Ankers gehalten sind. Das freie Ende des stabförmigen Längenabschnittes ragt dabei in die aussen gelegene Schale hinein, während der flach gehaltene Teil des Ankers in der innen gelegenen Schale z.B. in Dünnbettmörtel gehalten ist.Such air layer anchors are used to connect double-layer masonry e.g. the connection of a shell Lime sandstone or aerated concrete on the one hand and another, external masonry shell on the other hand, being in the Air layer between these two shells of insulation boards can be arranged by that in the air layer arranged rod-shaped longitudinal section of the anchor held are. The free end of the rod-shaped section protrudes thereby into the outer shell, while the flat held part of the anchor in the inner shell e.g. in Thin bed mortar is kept.

Bei den bekannten Luftschichtankern dieser Art (GB-A-2190938) wird der stabförmige Längenabschnitt aus einem Längenabschnitt des Ankerrohlings geformt, dessen Breite wesentlich geringer ist als diejenige des flachen Längenabschnittes. Da die Rohlinge ausgestanzt werden, ergibt sich durch diese Breitenunterschiede ein nicht unerheblicher Werkstoff- bzw. Stanzverlust.In the known air layer anchors of this type (GB-A-2190938) the rod-shaped length section from a length section of the Anchor blank shaped, the width of which is significantly smaller than that of the flat length section. Because the blanks are punched out, results from these width differences a not inconsiderable loss of material or punching.

Ferner sind Luftschichtanker bekannt (GB-A-2259532), die an beiden Enden im Grundriss nach Art des Buchstabens W gestaltet, und zwar in der Weise, dass einzelne Anker aus einer Werkstoffbahn ohne Werkstoffabfall durch Scheren, Stanzen od. dgl. gewonnen werden können. Die W-förmige Gestalt der Luftschichtankerenden erschwert in erheblichem Masse das Aufspiessen von Dämmplatten für die Luftschicht bei der Erstellung des Mauerwerks.Air-layer anchors are also known (GB-A-2259532), the plan at both ends in the manner of Letter W designed in such a way that individual anchors from a material web without Material waste due to scissors, punching or the like can be won. The W-shaped shape of the Air layer anchoring ends to a considerable extent the impaling of insulation boards for the air layer the creation of the masonry.

Ausserdem sind Luftschichtanker für Mauerwerk bekannt (EP-A-0183362), bei denen die beiden im Mauerwerk anzuordnenden, im wesentlichen flach gehaltenen Ankerenden in der Seitenansicht gesehen wellenförmig geformt wurden, während der für die Luftschicht bestimmte Mittelabschnitt im Grundriss zickzackförmig verläuft und nach Fertigstellung des Ankerrohlings um 90° so verdreht wird, dass er im montierten Zustand des Ankers senkrecht angeordnet ist. Air-layer anchors for masonry are also known (EP-A-0183362), in which the two are in masonry to be arranged, kept essentially flat Anchor ends seen wavy in side view were formed during the air layer certain middle section in the plan zigzag runs and after completion of the Anchor blank is rotated by 90 ° so that it is in the assembled state of the anchor is arranged vertically.

Der Erfindung liegt die Aufgabe zugrunde, eine praktisch abfallfreie Herstellung der eingangs erwähnten Luftschichtanker mit einem flach gestalteten Ende und einem anderen, das Übrige des Ankers bildenden stabförmigen Abschnitt zu ermöglichen, ohne dabei jedoch die Funktionstüchtigkeit der Luftschichtanker zu beeinträchtigen und somit seine Ausreissfestigkeit zu vermindern.The invention has for its object a practically waste-free production of the beginning mentioned air layer anchor with a flat design End and another, the rest of the anchor to allow rod-shaped section without doing so however, the proper functioning of the air layer anchors impair and thus its tear resistance Reduce.

Zur Lösung dieser Aufgabe wird erfindungsgemäß der flache Abschnitt im Grundriß und/oder im Längsschnitt zickzack- oder wellenförmig gestaltet und der stabförmige Abschnitt des Luftschichtankers aus einem gerade verlaufende Seitenkanten aufweisenden Längenbschnitt des Ankerrohlings geformt, dessen Breite der Breite des zugehörigen flachen Abschnitts des Luftschichtankers entspricht, welche Breite des flachen Abschnittes zwischen seinen parallel verlaufenden, zickzack- oder wellenförmigen Rändern in der auf der Längsachse des Luftschichtankers senkrechten Richtung gemessen wird.To achieve this object, according to the invention, the flat one Section in plan and / or in longitudinal section zigzag or wave-shaped and the rod-shaped section of the air layer anchor from a straight one Longitudinal section of the anchor blank with side edges shaped, the width of which corresponds to the width of the associated flat Section of the air layer anchor corresponds to what width of the flat section between its parallel, zigzag or wavy edges in the on the Longitudinal axis of the stratified anchor vertical direction is measured.

Diese Aufgabe wird ebenfalls durch die Merkmale des Luftschichtankers des Anspruchs 2 gelöst.This object is also achieved by the features of the air layer anchor of claim 2.

Demgemäss kann der Rohling für die Herstellung des Ankers über seine Länge hinweg von gleicher Breite sein. Hieraus ergibt sich, dass Stanzabfälle vermieden werden können. Um unter dieser Voraussetzung auch noch die Ausreissfestigkeit zu erhöhen, kann noch eine Randprofilierung des flachen Abschnittes genutzt werden, die jedoch aus Gründen der Abfallvermeidung ebenfalls von besonderer Gestaltung sein muss. Aus diesem Grunde ist der flache Abschnitt im Grundriss flach zickzack- oder wellenförmig ausgeführt, und zwar so, dass bei der Stanzung aus einer Materialbahn ein zickzack- oder wellenförmiger Schnitt genügt, um zwei aufeinander folgende Anker bzw. Rohlinge voneinander zu trennen. Accordingly, the blank can be used for the manufacture of the anchor is the same over its length Width. This means that punching waste is avoided can be. Under this condition also the An edge profiling can also increase tear resistance of the flat section are used, but for reasons waste prevention should also be of special design got to. For this reason, the flat section is in the floor plan flat zigzag or wavy, so that when punching from a web of material a zigzag or wavy cut is enough to make two consecutive Separate anchors or blanks.

    • Luftschichtanker haben die Aufgabe, eine Verbindung zwischen einer inneren Schale 1 z.B. aus Kalksandsteinen bestehend und einer äusseren Schale 2 z.B. als Verblendung herzustellen. Zwischen diesen beiden Schalen befindet sich ein Hohlraum 3, der zum Teil mit einer Matte 4 aus einem Dämmstoff ausgefüllt sein kann.Air layer anchors have the task of connecting between an inner shell 1 e.g. consisting of limestone and an outer shell 2 e.g. to manufacture as a veneer. There is a cavity 3 between these two shells, partially filled with a mat 4 made of an insulating material can be.

    Diese Luftschichtanker bestehen aus Stahlblech mit einer Wandstärke von etwa 0.5 mm und werden durch Stanzen od. dgl. aus einer Werkstoffbahn 5 gemäss Fig. 7 gefertigt. Sie weisen einen stabförmigen Längenabschnitt 6 und einen flachen Abschnitt 7 auf, wobei jedoch der Längenabschnitt 6 noch in einen mittleren, im wesentlichen rohrförmigen Abschnitt 8 und einen profilierten Abschnitt 9 unterteilt ist. Der Abschnitt 7 durchsetzt dabei die innere Schale 1, der rohrförmige Abschnitt 8 den Hohlraum 3 und der profilierte Abschnitt 9 die äussere Schale 2.These air layer anchors are made of sheet steel with a Wall thickness of about 0.5 mm and are stamped or the like. made of a material web 5 according to FIG. 7. You point a rod-shaped length section 6 and a flat one Section 7, but with the length section 6 still in a central, substantially tubular section 8 and a profiled section 9 is divided. Section 7 penetrates the inner shell 1, the tubular section 8 the cavity 3 and the profiled section 9 the outer Shell 2.

    Um die erfindungsgemässen Anker besonders abfallarm durch Stanzen od. dgl. aus der Werkstoffbahn 5 herstellen zu können, ist aufgrund der Erfindung der stabförmige Längenabschnitt 6 aus einem Längenabschnitt des streifenförmigen Rohlings 10 gefertigt, dessen Breite der Breite B des flachen Abschnitts 7 entspricht. Der Durchmesser D gemäss Fig. 4 entspricht also der Breite B gemäss Fig. 5.To the anchor according to the invention is particularly low in waste To be able to produce stamping or the like from the material web 5, is the rod-shaped longitudinal section 6 due to the invention from a length section of the strip-shaped blank 10 manufactured, the width of the width B of the flat portion 7th corresponds. The diameter D according to FIG. 4 thus corresponds to that Width B according to FIG. 5.

    Die sich hieraus ergebenden Vorteile sind insb. aus den Fig. 7 und 8 zu erkennen :The advantages resulting from this are in particular from FIG. 7 and 8:

    Zur Herstellung der Luftschichtanker wird eine Werkstoffbahn 5 benutzt, die an beiden Rändern eine Lochreihe 11 aufweist, die eine Führung der Werkstoffbahn 5 ermöglicht, zugleich aber auch aufgrund des Lochabstandes die Breite der Rohlinge 10 bestimmt. Dem Lochabstand entsprechend werden von einem Loch zu gegenüberliegenden Loch der beiden Lochreihen 11 durch Stanzen od. dgl. quer verlaufende Schnitte 12 vollzogen, wobei jedoch die Schnittlänge bzw. die Breite der Werkstoffbahn so gross gewählt sind, dass mit jedem Schnitt 12 zwei mit den profilierten Abschnitten 9 einander zugekehrte Anker - wie in Fig. 8 dargestellt - gefertigt werden können. Es versteht sich, dass mit jedem Schnitt eventuell nur ein Anker, aber auch drei oder mehrere bzw. jeweils ein Vielfaches von Zwei an Ankern gewonnen werden können. A material web 5 is used to manufacture the air layer anchors used, which has a row of holes 11 on both edges, the allows the material web 5 to be guided, but at the same time also determined the width of the blanks 10 based on the hole spacing. According to the hole spacing from a hole opposite hole of the two rows of holes 11 by punching or the like. Transversal cuts 12 are made, however the length of cut or the width of the material web is so great are chosen so that with each cut 12 two with the profiled sections 9 facing anchors - as in Fig. 8 shown - can be manufactured. It goes without saying that with each cut there may be only one anchor, but also three or more or a multiple of two each on anchors can be won.

    Nach Anbringung von Schnitten 12 werden zunächst die Ränder der Rohlinge 10 zur Erzeugung der stabförmigen Längenabschnitte 6 schrittweise bearbeitet, um so zunächst den Längenabschnitt 6 rohrförmig gemäss Fig. 8 zu formen und dann durch Eindrücken des rohrförmigen Längenabschnitts 6 den Abschnitt 9 zu bilden; diese Bearbeitung erstreckt sich über den Bereich S. Vorteilhaft ist es dabei, wenn das dafür benutzte Werkzeug im Sinne des Doppelpfeiles 20 quer zur Werkstoffbahn 5 verstellbar ist. Dadurch können unterschiedlich lange Längenabschnitte 8 und folglich unterschiedlich lange Anker mit einfachen Mitteln erzeugt werden. Bei einem aussermittigen Werkzeug für den Bereich S würden dann zwei Anker unterschiedlicher Länge entstehen.After making cuts 12, the edges of the Blanks 10 for producing the rod-shaped longitudinal sections 6 processed step by step, so that the length section 6 8 tubular and then by pressing of tubular length section 6 to form section 9; this processing extends over the area S. It is advantageous if the tool used for this The sense of the double arrow 20 is adjustable transversely to the material web 5 is. Length sections 8 of different lengths can thereby be and consequently anchors of different lengths with simple means be generated. With an eccentric tool for the Area S would then be two anchors of different lengths arise.

    Vor dem Abtrennen der beiden Anker werden die flachen Abschnitte 7 geformt, auf deren Gestaltung noch eingegangen wird. Beim Fertigprodukt sind im Abschnitt 7 die Halbkreise h aus den Lochreihen 11 erhalten, da die aussen gelegenen Ränder 7' neben den Lochreihen 11 verwertet werden.Before separating the two anchors, the flat ones Sections 7 formed, the design of which is still discussed becomes. For the finished product, the semicircles are in section 7 h obtained from the rows of holes 11, since the outer edges 7 'next to the rows of holes 11 can be used.

    Es versteht sich, dass eine solche Herstellung bestimmte Folgewerkzeuge und maschinelle Abläufe der Stanzungen und dgl. voraussetzt, die jedoch nicht Gegenstand der Erfindung sind. Wichtig ist jedoch, dass unmittelbar aufeinander folgende streifenförmige Rohlinge erzeugt werden, aus denen die Luftschichtanker zu fertigen sind. Dabei wird Abfall vermieden; Stanzabfälle können nicht entstehen.It is understood that such manufacture determined Follow-up tools and machine processes of punching and the like assumes that are not the subject of the invention. It is important, however, that immediately successive strip-shaped blanks are produced, from which the Air-layer anchors are to be manufactured. Waste is avoided; Punching waste cannot arise.

    Wie aus Fig. 7 erkennbar ist, verlaufen die Schnitte 12 im Bereich des rechten Randes der Werkstoffbahn 5 schwach zickzackförmig, während sie sonst gerade verlaufen. Die Gestalt der Schnitte 12 ist dabei so gewählt, dass der für den rechten Anker vorgesehene flache Abschnitt 7 seitlich von zickzackförmigen Rändern begrenzt ist, während alle übrigen Abschnitte gerade verlaufen bzw. gerade verlaufende Seitenkanten aufweisen, was auch für den flachen Abschnitt 7 des links wiedergegebenen Ankers der Fall ist.As can be seen from FIG. 7, the cuts 12 run in the Area of the right edge of the material web 5 weak zigzag while they are otherwise straight. The shape the section 12 is chosen so that the right one Anchor provided flat section 7 laterally from zigzag edges is limited while all the rest Sections run straight or straight Have side edges, which also applies to the flat section 7 of the anchor shown on the left is the case.

    Um ohne Stanzabfall eine erhöhte Ausreissfestigkeit der Anker herbeiführen zu können, sind aufgrund der Erfindung zwei Massnahmen einzeln oder in Kombination miteinander möglich :

  • 1. Örtliche Einschnitte an den Seitenkanten der Abschnitte 7 zur Erzielung eines Formschlusses innerhalb der innereren Schale 1 erübrigen sich, wenn die flachen Abschnitte 7 insg. zickzack- oder wellenförmig verlaufen, und/oder
  • 2. besondere Längsprofilierungen im Sinne von Fig. 6
    • angewendet werden.In order to be able to achieve an increased pull-out strength of the anchors without punching waste, two measures are possible individually or in combination with one another on the basis of the invention:
  • 1. Local incisions on the side edges of the sections 7 to achieve a positive fit within the inner shell 1 are unnecessary if the flat sections 7 run in a zigzag or undulating manner, and / or
  • 2. Special longitudinal profiles in the sense of FIG. 6
    • be applied.

    Zu 1. : Die Anker gemäss Fig. 1 - 3 - vgl. auch den rechts gemäss Fig. 7 erstellten Anker, der dem Anker gemäss Fig. 2 entspricht - weisen flache Längenabschnitte 7 auf, die schwach zickzackförmig verlaufen. Ein aus zwei symmetrisch angeordneten Schenkeln 13 gleicher Länge bestehender V-Abschnitt 14 weist einen Ausschlag A auf, der etwa 2 - 4 mm, insb. 3 mm beträgt, und zwar bei einer Gesamtlänge des Abschnittes 7 von etwa 95 mm und einer Länge der Schenkel 13von etwa 25 - 35 mm.Re 1.: The anchors according to Fig. 1 - 3 - cf. also the one on the right The anchor created according to FIG. 7, the anchor according to FIG. 2 corresponds - have flat lengths 7, which are weak run zigzag. One of two symmetrically arranged Legs 13 of the same length existing V-section 14 has a rash A that is about 2 - 4 mm, especially 3 mm, with a total length of section 7 of approximately 95 mm and a length of the legs 13 of about 25-35 mm.

    Die beiden Seitenkanten 15 des Abschnittes 7 verlaufen dabei parallel zueinander. In Verfolg dieses Gedankens kann auch eine wellenförmig verlaufende Seitenkante 15 genutzt werden. The two side edges 15 of section 7 run here parallel to each other. Following this thought, one can wavy side edge 15 can be used.

    Es sei erwähnt, dass bei einem Abschnitt 7 mit einer Länge von etwa 95 mm der profilierte Abschnitt 9 eine Länge von etwa 40 mm erhält bei einer Gesamtlänge des Ankers von etwa 21 0 - 300 mm.It should be mentioned that for a section 7 with a length of about 95 mm, the profiled section 9 has a length of about 40 mm receives a total length of the anchor of approximately 21 0-300 mm.

    Zu 2. : Aufgrund der Erfindung soll weiterhin eine besondere Längsprofilierung im Sinne des Schnittbildes gemäss Fig. 6 genutzt werden können. Wie aus den Fig. 1 - 3 erkennbar ist, erhält der flache Abschnitt 7 flache Einpressungen 19, die gemäss Fig. 1 zum stabförmigen Abschnitt 6 hin gerichtete Dreiecke 16 und gemäss Fig. 2 ineinander greifende, ebenfalls zum Abschnitt 8 hin zeigende Winkel 17 sind. Wichtig ist dabei, dass alle Einpressungen 19 wechselseitig in der Weise vorgesehen sind, dass sie einmal von oben nach unten und von unten nach oben gerichtet sind. Die Einpressungen 19 liegen somit zum Teil oberhalb und zum anderen unterhalb der durch den flachen Abschnitt 7 bestimmten Hauptebene. Vorzugsweise werden die Einpressungen auch so angeordnet, dass auf eine nach oben gerichtete eine nach unten gerichtete Einpressung 19 folgt. Wie aus Fig. 6 erkennbar ergibt sich dadurch im wesentlichen ein zickzack- bzw. wellenförmiger Querschnittsverlauf, der den Formschluss in der Schale 1 besonders erhöht und lediglich durch bleibende Verformung des Rohlings 10 und nicht durch Ausstanzungen erzeugt wird, die wiederum zu Abfällen führen.Re 2.: Due to the invention, a special should continue Longitudinal profiling in the sense of the sectional view according to FIG. 6 can be used. As can be seen from FIGS. 1-3, the flat section 7 receives flat pressings 19 which 1 directed towards the rod-shaped section 6 Triangles 16 and according to FIG. 2 interlocking, also for Section 8 angles 17 are. Important is doing that all the pressings 19 mutually in the way are provided that they go from top to bottom and from are directed upwards at the bottom. The pressings 19 lie thus partly above and partly below that by the flat section 7 certain main plane. Preferably be the pressings are also arranged so that on top of one directed a downward pressing 19 follows. How 6, this essentially results in a zigzag or wavy cross-sectional profile that the Form fit in the shell 1 particularly increased and only by permanent deformation of the blank 10 and not by Die cuts are produced, which in turn lead to waste.

    Es sei bemerkt, dass die zu 1. und 2. erwähnten Vorschläge gegebenenfalls für sich allein und auch unabhängig von dem Vorschlag benutzt werden können, nach dem der stabförmige Abschnitt 8 aus einem Längenabschnitt geformt wird, der eine dem flachen Abschnitt entsprechende Breite B aufweist. It should be noted that the suggestions mentioned on 1st and 2nd if necessary for themselves and also independently of that Proposal can be used according to the rod-shaped Section 8 is formed from a length section, the one has the width B corresponding to the flat section.

    Ferner sei bemerkt, dass es vorteilhaft ist, wenn die Tiefe T der wechselseitig anzubringenden Einpressungen 19 gemäss Fig. 6 etwa das Ein- bis Dreifache der Wandstärke des Ankers entspricht, wobei jedoch selbstverständlich auf die vorgesehenen Bemessungen der inneren Schale 4 Rücksicht zu nehmen ist.. Auch ist es möglich, gegebenenfalls den Abschnitt 7 flach, eben zu belassen, also dort auf Einpressungen zu verzichten, wobei dann allerdings vorzugsweise die wellen- oder zickzackförmige Gestalt des flachen Abschnitts 7 gewählt wird.It should also be noted that it is advantageous if the depth T of the mutually to be pressed-in 19 according to FIG. 6 about one to three times the wall thickness of the anchor corresponds, but of course to the the intended dimensions of the inner shell 4 is take .. Also it is possible, if necessary, the section 7 flat, to be left flat, i.e. there towards press-in waive, but then preferably the wave or zigzag shape of the flat section 7 is selected.

Method of producing a cavity wall tie for brickwork, which tie is formed from a thin-walled material, preferably steel, the cavity wall tie having a flat configuration at one end and including a different rod-like portion (6), which forms the remaining part of the cavity wall tie and is formed by deforming the tie material, characterised in that the flat portion (7), when viewed from above and/or in longitudinal section, has a zigzag-shaped or undulatory configuration, and the rod-like portion (6) of the cavity wall tie is shaped from a longitudinal portion of the tie blank (10), which portion has rectilinearly extending lateral edges and a width (B) which corresponds to the width of the associated flat portion of the cavity wall tie, which width of the flat portion is measured between its parallel-extending, zigzag-shaped or undulatory edges in the direction perpendicular to the longitudinal axis of the cavity wall tie.
    2. Cavity wall tie for brickwork, which tie is obtainable by the method according to claim 1 and is formed from a thin-walled material, preferably steel, the cavity wall tie having a flat configuration at one end and including a different rod-like portion, which forms the remaining part of the cavity wall tie and is formed by deforming the tie material, characterised in that the flat portion (7), when viewed from above and/or in longitudinal section, has a zigzag-shaped or undulatory configuration and includes indentations which are triangles (16) or chevrons (17) orientated towards the rod-like portion (6).
    3. Cavity wall tie according to claim 2, characterised in that the zigzag or undulation depth (A) is about 2 - 4 mm when viewed from above.
    4. Cavity wall tie according to claim 2, characterised in that the indentations (19) are alternately provided on the flat portion (7), the depth (T) of the indentations being about one- to three-times the wall thickness of the cavity wall tie.
    5. Cavity wall tie according to claim 2, characterised in that the chevrons (17) follow one another in such a close manner that they engage in one another.
    6. Cavity wall tie according to claim 2, characterised in that the triangles (16) form a row and are disposed with a mutual spacing therebetween, which spacing is shorter than the extent of the triangles (16) when viewed with respect to the longitudinal direction of the tie.
    7. Cavity wall tie according to claim 2, characterised in that an undulatory or zigzag-shaped portion (14) has a length of 50 - 70 mm.
    8. Method according to claim 1, characterised in that a material web (5) is provided with transversely orientated incisions (12), which extend parallel to one another and are produced by stamping, for example, so as to produce strips which are intended to form tie blanks and are still shaped continuously to form a cavity wall tie.
    9. Method according to claim 8, characterised in that the incisions (12) extend from holes, which are disposed in a row (row of holes 11) and are situated laterally in the material web (5), and in that the material strips (7'), which are situated laterally externally adjacent the holes, are divided so as to separate the cavity wall ties.
    10. Method according to claim 9, characterised in that two or more strip-like tie blanks, which lie one behind the other, are formed with one incision (12).
    11. Method according to claim 10, characterised in that, when there are two tie blanks, the flat portions (7) of the two ties are so processed that they lie laterally externally on the material web (5).
    12. Method according to claim 8, characterised in that two or more strip-like tie blanks, which lie one behind the other, are formed with one incision, and these blanks are processed in such a manner that rod-like portions of adjacent ties face one another.
    13. Method according to claim 8 and possibly 12 for producing a cavity wall tie, the rod-like portion (6) of which has a substantially tubular portion (8) and, at the free end of the cavity wall tie, a profiled portion (9), characterised in that the tools, which are used to form the profiled portion (9), are displaced transversely relative to the material web (5) so as to produce cavity wall ties of a modified length.
