Abstract

A shear-load chuck which is mounted between two members and has a multi-layer structure for transmitting dynamic loads. The multi-layer shear-load chuck is mounted on one surface of a junction like in the traditional bushing of a shear load chuck. A support basket is arranged correspondingly on both sides of the junction and has an end plate as well as at least one strap-like loop. The end plate forms together with the at least one strap-like loop a closed load system. The support basket is attached to the shear-load chuck on one surface of the junction, while it is attached to the bushing on the other surface of the junction. It is further possible to change the cross-sectional shape of the multi-layer shear-load chuck as well as the structural shape of the strap-like loop.

Description

Querkraftdornlagerung Shear force mandrel storage
Die vorliegende Erfindung betrifft eine Querkraftdornlagerung zur Uebertragung dynamischer Belastungen, bestehend aus einem Querkraftdorn, einer Querkraftdomlagerhulse sowie mindestens einem die Lagerhulse und einem den Querkraftdorn haltenden Lagerkorb .The present invention relates to a transverse force mandrel bearing for transmitting dynamic loads, consisting of a transverse force mandrel, a transverse force dome bearing sleeve and at least one bearing cage and a bearing basket holding the transverse force mandrel.
Querkraftdorne sind Verbindungs- und Druckverteilungselemente für zwei in der gleichen Ebene verlaufende Betonteile, die voneinander durch eine Fuge getrennt sind. Aus der EP-A- 0' 119 '652 ist eine Querkraftdornlagerung bekannt, die wie üblich aus einem Querkraftdorn, einer Querkraftdo lagerhulse sowie einem die Lagerhulse haltenden Lagerkorb bestent. Ferner sind am Lagerkorb Stirnplatten angeordnet, die lediglich der Fixierung der Querkraftdomlagerhulse an einer Verschalung wahrend der Erstellung der Betonpiatte dienen. Der Lagerkorb besteht aus einer Anzahl geschlossener Schlaufen aus Armierungsstahldrahten . Die Schlaufen liegen in Ebenen parallel zur Verlaufsrichtung der Fuge.Shear force mandrels are connecting and pressure distribution elements for two concrete parts running in the same plane, which are separated from each other by a joint. From EP-A-0 '119' 652 a transverse force mandrel bearing is known which, as usual, consists of a transverse force mandrel, a transverse force bearing sleeve and a bearing basket holding the bearing sleeve. Furthermore, end plates are arranged on the storage basket, which only serve to fix the transverse force dome bearing sleeves to a casing during the production of the concrete slab. The storage basket consists of a number of closed loops made of reinforcing steel wires. The loops lie in planes parallel to the direction of the joint.
Neben dem genannten Querkraftdornlagersystem sind e ne Vielzahl weiterer Querkraftdornlagerungen bekannt. Eines der wesentlichsten Probleme der statischen Querkraftdornlagerung besteht darin, dass im Bereich der Querkraftdorne beziehungsweise im Bereich der Querkraftdornlagerhulsen oft die Druckgrenzen für Beton wesentlich überschritten werden. Dieses Problem lasst s ch reduzieren, indem man die Anzahl αer Querkraftdorne in der Verlaufsrichtung der Dehnungsfuge erhöht, doch fuhrt dies zu erheblichen Mehrkosten. Eine Querkraftdornlagerung, die auch dynamischen Belastungen standhalt, wird πedoch hierdurch nicht erreicht.In addition to the aforementioned shear force bearing system, a large number of further shear force bearing arrangements are known. One of the most important problems of static shear force bearing consists in the fact that in the area of the lateral force mandrels or in the area of the lateral force mandrel bearing sleeves, the pressure limits for concrete are often significantly exceeded. This problem can be reduced by increasing the number of transverse shear pins in the direction of the expansion joint, but this leads to considerable additional costs. However, this does not result in a shear force mandrel bearing that can also withstand dynamic loads.
Ein System, das in Bezug auf die Querkraftdornlagerung vermutlich auch dynamischen Belastungen gerecht werden konnte, zeigt die EP-A-0 '032 ' 105 (U.C. Aschwanden). Die Lagerkorbe werden hier durch mehr oder weniger allseitig geschlossene Becher gebildet. Innerhalb des Bechers wird dabei zwar auch die zulassige Druckgrenze des Betons überschritten, doch erfolgt die Kraftübertragung auf den Becher und der oberhalb des Bechers verlaufende Beton wird soweit entlastet, dass hier die zulassige Druckgrenze mcnt mehr überschritten wird.EP-A-0 '032' 105 (U.C. Aschwanden) shows a system which presumably could also cope with dynamic loads in relation to the shear force mandrel bearing. The storage baskets are formed here by cups that are more or less closed on all sides. The permissible pressure limit of the concrete is also exceeded within the cup, but the force is transferred to the cup and the concrete running above the cup is relieved to the extent that the permissible pressure limit mcnt is exceeded here more.
Eine Weiterentwicklung zeigt die EP-A-0 ' 773 ' 324. Auch mer wird wiederum das Problem der statischen Belastung und insbesondere die Kraftverteilung zur Vermeidung des Ueber- schreitens der zulassigen Druckgrenze des Betons betrachtet. Als Losung wird auch hier einer zur Fuge hin gerichtete Stirnplatte vorgesehen, wobei an jeder Stirnplatte eine in den Baukorper hineinragende Platte angeordnet ist. Diese Platte liegt jeweils auf der Seite des Dorns beziehungsweise der Hülse, die bei der Uebertragung der statischen Reaktionskrafte auf das entsprechende Bauteil der αruck- belasteten Seite des Dorns beziehungsweise der Hülse gegenüberliegt. Des weiteren wird hier noch vorgeschlagen, diese in den Baukorper hineinragenden Platten sozusagen nutzlos auch noch an der gegenüberliegenden Seite vorzusehen, um sicher zu sein, dass das Element den statxschen Belastungen auch dann standhalt, wenn es aus Unachtsamkeit verkehrt herum eingebaut werden wurde.A further development is shown in EP-A-0 '773' 324. Again, the problem of the static load and in particular the force distribution to avoid exceeding the admissible pressure limit of the concrete is also considered. As a solution, an end plate facing the joint is also provided, with a plate protruding into the structure being arranged on each end plate. This plate lies on the side of the mandrel respectively the sleeve which, when the static reaction forces are transmitted to the corresponding component, lies opposite the side of the mandrel or the sleeve which is under pressure. Furthermore, it is also proposed here to provide these panels protruding into the structure uselessly, so to speak, on the opposite side, to be sure that the element can withstand the static loads even if it has been installed the wrong way round due to carelessness.
Die Anmeldenn hat bereits ein Verfahren entwickelt, mittels dessen sich Querkraftdorne herstellen lassen, die einen spielfrei eingezogenen Kern aufweisen und einen Mantel, der diesen Kern überragt und deren Enden mittels Kunst- stoffpfropfen gegen Korrosion geschützt sind. Der hierbei im Mittelpunkt stehende Gedanke besteht darin, einerseits Querkraftdorne herzustellen, die vorzugsweise überwiegend aas relativ preiswertem Baustahl bestehen unα iediglicr ein Mantelrohr aus Edelstahl aufweisen. Solche Querkraf dorne haben sich zur Uebertragung statischer Belastungen bestens bewahrt. Sie lassen sich auch ausserst präzis herstellen u"α sind ausgezeichnet gegen Korrosion geschützt.The applicant has already developed a method by means of which shear force mandrels can be produced which have a core which is drawn in without play and a jacket which projects above this core and whose ends are protected against corrosion by means of plastic plugs. The focus here is on the one hand to produce shear force mandrels which preferably consist predominantly of relatively inexpensive structural steel and have a stainless steel jacket tube. Such transverse force mandrels have been well preserved for the transmission of static loads. They can also be manufactured extremely precisely and are perfectly protected against corrosion.
Ausgehend von diesem Stand der Technik hat man sicn die Aufgabe gestellt, erstmals eine Querkraftdornlagerung zu schaffen, die insbesondere für dynamische Belastungen geeig¬ net ist. Bis heute sind keine Querkraftdornlagerungen auf dem Markt, die für dynamische Belastungen zugelassen sind. Bei dynamischen Belastungsversuchen an Querkraftdornen, wie sie aus der EP-A-0 ' 765 ' 967 bekannt geworden sind, hat man festgestellt, dass diese gegenüber Querkraftdornen, die aus einem einzigen monoferπten Stahl bestehen, erheblich bessere dynamisch-physikalische Eigenschaften gezeigt haben. Basierend auf dieser Erkenntnis wurden weitere Versuche mit mehrlagigen Querkraftdornen durchgeführt, die allesamt bessere Resultate aufzeigten als Querkraftdorne aus mono- ferπtem Material. Hierbei werden unter monofernten Querkraftdornen solche Stabe verstanden, die sicn aus einer einzigen Stahllegierung zusammensetzen und nicht mehrere Lagen aus gleichen Stahllegierungen oder unterschiedlichen Stahllegierungen aufweisen.Starting from this prior art has SiCN with the task of creating a shear load dowel mounting which is cutlery are ¬ especially for dynamic loads. To date, there are no shear force bearings on the market that are approved for dynamic loads. In dynamic load tests on shear force mandrels, as are known from EP-A-0 '765' 967, it has been found that these have shown significantly better dynamic-physical properties than shear force mandrels which consist of a single monofiber steel. Based on this knowledge, further tests were carried out with multi-layer shear force mandrels, all of which showed better results than shear force mandrels made of monofilament material. Here, mono-distant shear force mandrels are understood to mean rods which are composed of a single steel alloy and do not have multiple layers of the same steel alloy or different steel alloys.
Die Erfindung zeigt des weiteren ein neues Verfahren zur Herstellung von Querkraftdornen auf, da insbesondere bei mehr als zwei Lagen das eingangs erwähnte von der Anmelderin bereits geschützte Verfahren weniger geeignet ist.The invention furthermore shows a new method for producing transverse force mandrels, since the method mentioned at the outset, which is already protected by the applicant, is less suitable, particularly in the case of more than two layers.
Es ist folglich die Aufgabe der vorliegenden Erfindung, erstmals eine Querkraftdornlagerung zu schaffen, die für dynamische Belastungen geeignet ist.It is therefore the object of the present invention to provide a transverse force mandrel bearing that is suitable for dynamic loads for the first time.
Diese Aufgabe erfüllt eine Querkraftdornlagerung mit den Merkmalen des Patentanspruches 1.This task is fulfilled by a transverse force mandrel bearing with the features of claim 1.
Für die dynamische Querkraftdornlagerung ist das Gesamtkonzept bestehend aus einem Querkraftdornlagerkorb mit den Merkmalen des Patentanspruches 1 sowie einem mehrlagigen Querkraftdorn und deren gemeinsame Anordnung von essentieller Bedeutung. Für die dynamischen Belastungen müssen diese beiden Elemente aufeinander abgestimmt sein.For the dynamic shear force mandrel storage, the overall concept consists of a shear force mandrel bearing basket with the Features of claim 1 and a multi-layer transverse force mandrel and their common arrangement of essential importance. For the dynamic loads, these two elements must be coordinated.

Figur 4c einen Querschnitt durch den Querkraftdorn wie in Figur 4a verwendet entlang der Linie D-D zeigt .Figure 4c shows a cross section through the transverse force mandrel as used in Figure 4a along the line D-D.
Die beiden unter dynamischer Belastung stehenden Bauteile, die mittels Querkraftdornlagerung miteinander in Verbindung stehen, sind hier mit Bi und B2 gekennzeichnet. In der Figur la ist andeutungsweise dargestellt, dass die Elemente im Beton eingelagert sind. Um die weiteren Zeichnungen nicht unnötig zu belasten, ist die Darstellung des Betons weggelassen worden. Im wesentlichen ist die Querkraft- dornlagerung bezüglich der zu überbrückenden Fuge F symmetrisch gestaltet. Die Querkraftdornlagerung besteht wie üblich aus dem Querkraftdorn 1, einer Querkraftdomlagerhulse 2 sowie Lagerkorben 3.The two components under dynamic load, which are connected to each other by means of transverse force mandrel bearings, are marked here with Bi and B 2 . In the figure la is indicated that the elements are embedded in the concrete. In order not to unnecessarily burden the other drawings, the illustration of the concrete has been omitted. Essentially, the transverse force mandrel mounting is designed symmetrically with respect to the joint F to be bridged. The shear force mandrel bearing consists, as usual, of the shear force mandrel 1, a shear force dome bearing sleeve 2 and bearing cages 3.
Die LagerKorbe 3 bestehen aus mindestens zwei Elementen, nämlich einer Stirnplatte 4 und einer traggurtartigen Schlaufe 5. Dabei ist wesentlich dass die traggurtahnliche Schlaufe 5 mit der Stirnplatte 4 zusammen ein geschlossenes Kraftesystem bildet. Die Stirnplatte 4 ist bundig mit der z„r Fuge hm gerichteten Stirnflache des jeweiligen Betonteiles Bι,B2 im Beton eingelassen. Die traggurtartigen Schlaufen sind so angeordnet, dass sie die auf den Querkraftdorn auftretenden Wechsellasten auf die Stirnplatte zu übertragen vermögen. Dies wird durch die traggurtartige Ausgestaltung der Schlaufen 5 erreicht. Im Prinzip lassen sich oie traggurtartigen Schlaufen 5 m verschiedenen Gestaltungsformen ausbilden. Sie können genau die gleiche Breite aufweisen wie die Stirnplatten 4 oder schmaler oder breiter als diese sein. In der Ausfuhrung gemass den Figuren 4 weist die traggurtartige Schlaufe 5 dieselbe Breite wie die Stirnplatte 4 auf, wahrend die übrigen drei Ausfuhrungsformen Varianten darstellen, bei denen die traggurtartigen Schlaufen schmaler als die Stirnplatte 4 sind. Der Querkraftdorn 1 beziehungsweise die Querkraftdomlagerhulse 2 können die traggurtartige Schlaufe 5 durchsetzen, wie dies die Ausführungen gemass den Figuren 1 und 4 zeigen oder sie können von diesen Schlaufen 5 umfangen sein, wie dies die Ausfuhrung gemass der Figur 2 darstellt. In beiden Varianten haben die Schlaufen 5 jedoch traggurtartige Funktionen. Dies wird nocn deutlicher bei der Ausfuhrung nach Figur 3. Hier sind pro Seite zwei Traggurte verwendet, die zusammen ein geschlossenes Kraftesystem mit der Stirnplatte 4 bilden. Bei dieser Variante greift am oberen Ende der einen Stimplatte eine traggurtartige Schlaufe 5' an, die sich bis unterhalb der Querkraftdomlagerhulse 2 erstreckt. Dies gibt eine Tragkonstruktion ähnlich einer Hangebrucke für Belastungen m die eine Richtung, wahrend sich zweite traggurtartige Schlaufen 5" vom unteren Ende der Stirnplatte 4 bis zum oberen Bereich der Querkraftdomlagerhulse 2 erstrecken. Selbstverständlich laufen diese traggurtartigen Schlaufen seitlich an der Querkraftdomlagerhulse 2 vorbe_. Analoges trifft natürlich auf der gegenüberliegenden Seite zu, wo die traggurtartigen Schlaufen 5' und 5" statt mit der Querkraftdomlagerhulse 2 direkt mit dem Querkraf dorn 1 in Verbindung stehen.The storage baskets 3 consist of at least two elements, namely an end plate 4 and a carrying belt-like loop 5. It is essential that the carrying belt-like loop 5 together with the end plate 4 is a closed one Force system forms. The end plate 4 is embedded in the concrete flush with the end surface of the respective concrete part B 1, B 2 directed towards the joint. The riser-like loops are arranged so that they are able to transfer the alternating loads that occur on the transverse force mandrel to the end plate. This is achieved by the strap-like design of the loops 5. In principle, 5 m of different design forms can be formed like a carrying strap-like loops. They can have exactly the same width as the end plates 4 or be narrower or wider than this. In the embodiment according to FIGS. 4, the riser-like loop 5 has the same width as the end plate 4, while the other three embodiments represent variants in which the riser-like loops are narrower than the end plate 4. The transverse force mandrel 1 or the transverse force dome bearing sleeve 2 can pass through the carrying belt-like loop 5, as shown by the embodiments according to FIGS. 1 and 4, or they can be encompassed by these loops 5, as shown by the embodiment according to FIG. 2. In both variants, however, the loops 5 have shoulder strap-like functions. This becomes clearer in the embodiment according to FIG. 3. Here, two carrying straps are used on each side, which together form a closed power system with the end plate 4. In this variant, a shoulder strap-like loop 5 ′, which extends to below the transverse force dome bearing sleeve 2, engages at the upper end of the one end plate. This gives a support structure similar to a suspension bridge for loads m one direction, while the second carrying belt-like loops 5 "extend from the lower end of the end plate 4 to the upper region of the transverse force dome bearing sleeve 2. Of course, these carrying belt-like loops run past the lateral force dome bearing sleeve 2 Loops 5 'and 5 "are connected to the transverse force mandrel 1 instead of the transverse force dome sleeve 2.
Die in der Seitenansicht möglichen Formen der traggurtartigen Schlaufen 5 können beispielsweise trapezförmig sein, wobei man vorzugsweise die Form eines gleichschenkligen Trapezes wählt, dessen Hohe allerdings unterschiedlich sein kann, wie dies durch die strichlinierte Linie im Bauteil B. andeutungsweise eingezeichnet ist. Die Form der traggurtartigen Schlaufen 5 kann aber auch in etwa die Form eines Dreieckes aufweisen, wie dies die Figur 2a zeigt. Diese For"~ lasst sich selbstverständlich auch dann erreichen, wenn der Querkraftdorn beziehungsweise die Querkraftdornlagerhu-.se 2 die einzige traggurtartige Schlaufe 5 jeweils durchsetzen. Letzlicn kann aber auch die traggurtartige Schlaufe halbkreisförmig gestaltet sein, wie dies die Fig^r 4a zeigt. Um wahrend des Vergiessens mögliche Lunkerbildung innerhalb oes Lagerkorbes 3 zu vermeiden, sind die traggurtartiger Schlaufen vorzugsweise mit Entluftungsbohrungen oeziehungs- eise Entluftungslochern 6 m beliebigen Crossen und beliebiger Anzahl versehen, wie dies die verschiedenen Ausfuhrungsformen zeigen.The possible shapes of the shoulder strap-like loops 5 in the side view can be trapezoidal, for example, preferably choosing the shape of an isosceles trapezoid, the height of which can, however, be different, as is indicated by the dashed line in component B. The shape of the riser-like loops 5 can also have approximately the shape of a triangle, as shown in FIG. 2a. This For "~ let's of course also be achieved if the transverse force dowel or the Querkraftdornlagerhu-.se 2 5 enforce the only straplike loop each. But Letzlicn may be semicircular in shape, the straplike loop, as shown in FIGS ^ r 4a. In order to avoid possible formation of voids within the storage basket 3 during the casting process, the riser-like loops are preferably with ventilation holes or ventilation holes 6 m of any crosses and any number, as shown by the different embodiments.
Für die Uebertragung der dynamischen Belastungen ist die mehrlagige Ausgestaltung des Querkraftdornes 1 von absolut zwingender Notwendigkeit. Nur dank der mehrlagigen Ausgestaltung der Querkraftdorne lassen sich die pnysikalischen Eigenschaften erzielen, nämlich die erforderliche Wechsel- belastbarkeit gepaart mit der hohen Druckfestigkeit, Scnerfestigkeit und Elastizitatswerten . Querkraftoorne mit monoferritischem Querschnitt, d.h. Querkraftoorne, die in ihrer Gesamtheit aus einem Metall beziehungsweise einer Metallegierung und aus einem Stuck bestehen, haben diese gewünschten Paarungen der physikalischen Eigenschaften nicht erbracht. Diese Erkenntnis ist ausgesprochen überraschend. Bisher wurden mehrlagige Querkraftdorne im wesentlichen aus Kostengrunden sowie aus Gründen des Korrosionsschutzes verwendet; dass sich durch diesen laminaren Aufbau die physikalischen Eigenschaften des Querkra tdornes so einstellen lassen wurden, dass damit erstmals aucn Querkraft- dornlagerungen gebaut werden können, die dynamische Belastungen zu übertragen vermögen, war nicht vornersehbar .For the transmission of the dynamic loads, the multi-layer design of the transverse force mandrel 1 is absolutely imperative. The physical properties can only be achieved thanks to the multi-layer design of the shear force mandrels, namely the required load-bearing capacity combined with the high compressive strength, resistance to scoring and elasticity values. Shear force gates with a monoferritic cross-section, i.e. Shear force gates, which consist entirely of a metal or a metal alloy and a piece, have not produced these desired pairings of the physical properties. This finding is extremely surprising. Up to now, multilayer shear force mandrels have been used mainly for cost reasons and for reasons of corrosion protection; It was not foreseeable that this laminar structure would allow the physical properties of the transverse mandrel to be adjusted in such a way that it can also be used to build transverse force mandrel bearings that can transmit dynamic loads.
Prinzipiell lassen sich die erfmdungsgemassen Querkraftdorne mit allen üblich bekannten Querschnittsformen auch mehrlagig nerstellen. Nach wie vor v/erden die häufigsten Quer- schnittsformen vorhanden sein, wie insbesondere zylindrische Querkraftdorne sowie Querkraftdorne mit einem rechteckigen oder quadratischen Querschnitt. Wahrend Querkraftdorne ιr_t einem rechteckigen oder quadratischen Querschnitt prιnzιpιe_l aus einer Schichtung von mindestens zwei plattenformigen Stäben gebildet werden können, wird man jedoch üblicherweise eher drei oder mehr Schichten vorsehen. Dabei kann die ausserste Schicht auch als umhüllender Mantel ausgebildet sein. Auch die Verbindung zwischen den plattenformigen Stäben zu einem Querkraftdorn können selbstverständlich unterschiedlichster Natur sein. Neben Klebe- und Schweissverbmdungen kommen aucn form- und/oder kraftschlussige Verbindungen _n Frage. Dabei können Pakete von Platten entstehen, ähnlich w_e bei mehrlagigen Blattfedern, wobei die einzelnen Lager beispielsweise durch sie durchsetzende Nieten oder Stifte formschlussig untereinander verbunden sein können, oder seitliche Auskerbungen aufweisen, um schliesslich eine Verbindung durch eine Umreifung zu realisieren.In principle, the shear force mandrels according to the invention can also be multi-layered with all the known cross-sectional shapes. The most common cross-sectional shapes are still present, such as, in particular, cylindrical shear force mandrels and shear force mandrels with a rectangular one or square cross section. While shear force mandrels ιr_t a rectangular or square cross-section prιnzιpιe_l can be formed from a stratification of at least two plate-shaped bars, but usually three or more layers will be provided. The outermost layer can also be designed as an enveloping jacket. The connection between the plate-shaped bars to form a transverse force mandrel can of course be of the most varied nature. In addition to adhesive and welded connections, positive and / or non-positive connections are also possible. This can result in packets of plates, similar to multilayer leaf springs, whereby the individual bearings can be positively connected to one another, for example by rivets or pins penetrating them, or have side notches in order to finally realize a connection by strapping.
Bei den zylindrischen Ausfuhrungsformen der Querkraftdorne kommen ebenfalls zwei- oder mehrlagige Ausfuhrungen n Frage. Hierbei spielen die Durchmesserverhaltnisse selbstverständlich in Abhängigkeit der Mateπalkombination eine entsprechende Rolle. Dies zu optimieren wird Sache des Fachmannes sein, der dies auch in Abhängigkeit der zu erwartenden Kräfte und Bewegungen auslegen wird. Dynamische Belastungen auf Querkraftdornlagerungen treten ja in sehr verschiedenen Anwendungen auf, von Querkraftdornen, die Fahrbahnbetor- platten verbinden über Bodenplatten Parkhausern oder Lagerhausern bis zu komplexen Betonkonstruktionen, wie Tunnelrohren oder Betonkanalen. In all diesen Anwendungen können schneller oder langsamer auftretende Wechselbelastungen vorkommen, die nur vernunftig aufgenommen werden können mit Querkraftdornlagerungen, die für dynamische Belastungen ausgebildet sind. Bisher hat man sich hierbei mit erheblich überdimensionierten Querkraftdornlagerungen Geholfen, die an sich nur für statische Belastungen ausgelegt s nd und hat dabei die bei Wechsellasten auftretenden unter- schiedlicn gerichteten Kräfte praktisch summiert, um damit m einen faktisch starren Bereich zu gelangen, der somit wiederum cen statischen Belastungen entspricht.In the cylindrical designs of the shear force mandrels, two- or multi-layer designs are also possible. The diameter ratios naturally play a corresponding role depending on the material combination. It will be up to the person skilled in the art to optimize this, who will also interpret this as a function of the forces and movements to be expected. Dynamic loads on shear force mandrel bearings occur in very different applications, from shear force mandrels that connect roadway slabs to floor slabs or multi-storey car parks or warehouses to complex concrete structures such as Tunnel pipes or concrete channels. In all of these applications, alternating loads that occur faster or slower can occur, which can only be reasonably absorbed with shear force mandrel bearings designed for dynamic loads. So far, this has been helped with considerably oversized shear force mandrel bearings, which are only designed for static loads and have practically summed up the different forces that occur with alternating loads, in order to reach a de facto rigid area, which in turn cen corresponds to static loads.
Wie beispielsweise in der Figur 2c dargestellt, kann auch ein zylindrisch gestalteter Querkraftdorn aus mehr als zwei Lagen gefertigt werden. Für diesen Zweck eignet sich das aus der EP-A-0 ' 765 ' 967 bekannte Verfahren weniger. Ein besonders interessantes Verfahren zur Herstellung solcher Quer raft- dorne besteht darin, dass man über einen zentriscnen zylindriscnen Stab ein erstes Rohr schiebt, das mit einem gewissen Spiel diesen Stab umgibt und dann dessen Durchmesser durch ein Hammerverfahren auf den Kern völlig spielfrei aufhammert. Erstaunlicherweise lasst sich dabei ein ausserst genauer Stab erzielen, wobei die kraftschlussige Verbindung hervorragend ist. Auf einen derart geformten zweilagigen Kern kann problemlos auf dieselbe Art und Weise ein weiteres Ronr daruberge∑ogen werden, wiederum mit Spiel, wobei wiederum mittels einem Hammerverfahren der neue ausserste Mantel auf den bereits zweilagigen Kern aufgehämmert werden kann. Auf diese Weise lasst sich ein beliebig mehrlagiger Stab bilden, der enorme Festigkeitswerte aufweisen kann und dessen physikalische Eigenschaften praktisch für jeden Anwendungszweck massgeschneidert erreichbar sind.As shown, for example, in FIG. 2c, a cylindrically designed transverse force mandrel can also be produced from more than two layers. The method known from EP-A-0 '765' 967 is less suitable for this purpose. A particularly interesting process for the production of such cross-shaft mandrels is that a first tube is pushed over a central cylindrical rod, which surrounds this rod with a certain amount of play and then hammers its diameter onto the core without play using a hammer process. Surprisingly, an extremely precise rod can be achieved here, the non-positive connection being excellent. On a two-ply core shaped in this way, another ring can be easily pulled over it in the same way, again with play, whereby the new outermost jacket can be hammered onto the already two-ply core using a hammer process. On In this way, a multi-layered rod can be formed, which can have enormous strength values and whose physical properties can be achieved practically for every application.
In den meisten Fallen wird man sicherlich mit unterschiedlichen Stahllegierungen für die verschiedenen Lagen arbeiten. Es hat sich jedoch gezeigt, dass auch oei Beibehaltung der Stahllegierung allein durch die mehrlagige beziehungsweise mehrschichtige Konstruktion des Querkraft- dornes erheblich verbesserte Werte erzielbar sind.In most cases you will certainly work with different steel alloys for the different layers. It has been shown, however, that even if the steel alloy is retained, the multilayer or multilayer construction of the transverse force mandrel can achieve significantly improved values.
Es ist jedoch nicht zwingend, dass der Kern des Querkraft- dornes ein Stab ist. In Frage kommt auch die Variante, bei der der Kern ein innerstes Rohr ist und mehrere Rohre in mehreren Lagen darüber gezogen oder gehämmert sind. Schliesslich kann aber auch der Hohlraum des innersten Rohres aus pnysikalischen Gründen oder als Korrosionsschutz rit einer nartenden Masse ausgefüllt sein.However, it is not imperative that the core of the shear force mandrel is a rod. Also possible is the variant in which the core is an innermost tube and several tubes are pulled or hammered over it in several layers. Finally, the cavity of the innermost tube can also be filled with a nauseating mass for physical reasons or as corrosion protection.
Für die Erzielung der dynamischen Belastbarkeit, die hier f r den Dorn erforderlich ist, ist es erforderlich, d e Harte des mehrscnichtigen Domes zwischen den einzelnen Schichten zu variieren. Möglich ist es sowohl die Harte von aussen nacn innen zunehmend als auch abnehmend zu gestalten. Aus verschiedenen Gründen ist es besonders von Vorteil, die Harte von aussen nach innen zunehmend zu wählen. Für die Herstellung der mehrschichtigen Dorne mit mehreren Lagen, wobei die einzelnen Lagen rohrformig übereinander angeordnet sind, hat es sich erwiesen, dass ein besonders geeignetes Resultat erzielt wird, indem man die jeweils ausserste Schicht bei der Herstellung als Rohr mit Spiel aufschiebt und danach mittels einem bekannten Hammerverfahren auf den Kern kraftschlussig aufbringt. Auch hier kann oer Kern ein Stab oder ein ein- oder mehrschichtiges Rohr sein. Die beim Hammerverfahren erzielten Materialverdichtungen ergeben ein physikalisch günstigeres Produkt als ein durch thermische Verfahren kraftschlussig gebildeter mehrlagiger Dorn. In order to achieve the dynamic resilience required for the mandrel, it is necessary to vary the hardness of the multi-layer dome between the individual layers. It is possible to make the hardness from the outside to the inside increasing and decreasing. For various reasons, it is particularly advantageous to increasingly choose the hard one from the outside in. For the production of the multi-layer mandrels with several layers, the individual layers being arranged one above the other in a tube, it has been found that a particularly suitable result is achieved by pushing on the outermost layer during manufacture as a tube with play and then using a known hammer method applied to the core non-positively. Here too the core can be a rod or a single or multi-layer tube. The material compaction achieved with the hammer process results in a physically more favorable product than a multi-layer mandrel formed by the thermal process.
