Description

Die vorliegende Erfindung betrifft Lärmschutzwandsegmente mit mindestens einer Lärmschutzplatte aus Kunststoff und wenigstens einem Mittel zur Befestigung der Platte an einem Träger.The present invention relates to noise barrier wall segments with at least one noise protection plate made of plastic and at least one means for fixing the plate to a Carrier.

Plattensysteme der Eingangs beschriebenen Art sind in der Regel aus mehrere Quadratmeter großen Platten, insbesondere transparenten Kunststoffplatten, aufgebaut, wobei die Platten nebeneinander angeordnet sind und jeweils zwei benachbarte Platten von einem Träger zusammengehalten und am Boden fixiert werden. Dieser Träger ist üblicherweise ein Doppel-T-Träger, auf dessen einem T die zwei benachbarten Platten mit etwas Abstand voneinander und in einem Gummiprofil geschützt anliegen. Gehalten werden die Platten von einem Flachstahl, das auf den dem Doppel-T-Träger abgewandten Endbereichen der Platten aufliegt und das mittels mehrerer Befestigungsschrauben mit dem Doppel-T-Träger durch die Lücke zwischen den beiden Platten mit einem Doppel-T-Träger verbunden ist.Plate systems of the type described above are in the Usually from several square meters of plates, in particular transparent plastic plates, constructed, with the Plates are arranged side by side and two each adjacent plates held together by a carrier and be fixed to the ground. This carrier is customary a double T-beam, on one T the two adjacent panels with some distance from each other and in protected by a rubber profile. Are held the Plates of a flat steel on top of the double T-beam remote end portions of the plates rests and this by means of several screws with the double-T-beam through the gap between the two plates a double-T-carrier is connected.

Eine Lärmschutzwand dieser Art ist einfach aufzubauen, von den Trägerelementen her nicht kostspielig und sichert die Platten in akzeptabler Weise. Nachteilig ist jedoch, daß die Träger sehr breite Pfosten sind, damit die nötige Einspannung von jeweils 50 mm gewährleistet ist.A noise barrier of this kind is easy to build, from the carrier elements ago not expensive and secures the Plates in an acceptable way. The disadvantage, however, is that the straps are very wide poles, so that the necessary Clamping of 50 mm is guaranteed.

Werden in diese Träger Kunststoffscheiben eingespannt, dann kann diese Verlegetechnik zur Ausbildung einer freien Auflagerung führen, welche durch Zulassung einer geringen Winkelbewegung zwischen Pfosten und Kunststoffscheibe eine negative Auswirkung auf die Erfüllung der Forderung der zusätzlichen technischen Vorschrift Lärmschutzwand 1988 (ZDV LSW 88) nach maximaler Durchbiegung unter Verkehrslast von 175 hat.If plastic discs are clamped in this carrier, then This laying technique can be used to form a free Auflag lead, which by admission of a small Angular movement between post and plastic disc one negative impact on the fulfillment of the requirement of additional technical regulation noise barrier 1988 (ZDV LSW 88) after maximum deflection under traffic load from 175 has.

Aus dem DE-U 85 24 319.1 bzw. EP-A-0 213 521 sind Verglasungssprossen zur Errichtung von Lärmschutzwänden, die großflächige Scheiben aus durchsichtigem Kunststoff zwischen senkrechten Pfosten enthalten, bekannt geworden, die in etwa den Eingangs genannten Trägern entsprechen. Anstelle eines Doppel-T-Trägers kann bei diesen Systemen auch ein Vierkantrohr verwendet werden, das hinsichtlich seiner Abmessungen dem Doppel-T-Träger entspricht. Die einzelnen Platten werden mit Abstand voneinander auf eine der Seitenflächen des Vierkantrohres aufgelegt und mittels einer Klemmschiene und einer entsprechenden Anzahl von Schrauben durch die Lücke zwischen den einzelnen Platten gegen das Vierkantrohr geklemmt. Die Konstruktion ist hinreichend windstabil, benötigt jedoch hierfür verhältnismäßig breite Vierkantrohre.From DE-U 85 24 319.1 or EP-A-0 213 521 Glazing rungs for the construction of noise barriers, the large windows of transparent plastic between vertical posts, known, which correspond approximately to the entrance mentioned carriers. Instead of a double-T carrier can be used in these systems Also, a square tube can be used, in terms of its dimensions corresponds to the double-T-beam. The individual plates are spaced apart on one another the side surfaces of the square tube and placed by means of a clamping rail and a corresponding number of Screw through the gap between each plate clamped against the square tube. The construction is sufficiently wind stable, but needed for this relatively wide square tubes.

Abhilfe hierfür liefert beispielsweise die EP-A-0 530 512. Hierin wird ein Plattensystem offenbart, in welchem Kunststoffplatten nicht mit Abstand auf Stoß oder im wesentlichen außerhalb der Trägerauflagefläche überlappend verlegt sind, sondern einander teilweise überlappend durch die Überlappung und die Auflagefläche am Träger hindurch mit dem Träger verankert sind. Hierdurch kann die erforderliche Trägerbreite ohne Beeinträchtigung der Stabilität in etwa halbiert werden. Obwohl dies insbesondere für Wandsysteme und speziell bei durchsichtigen Lärmschutzwänden einen optisch gefälligeren Eindruck ergibt, da die Träger schlank sind und nicht mehr wie bisher plump wirken, macht die aus der EP-A-0 530 512 bekannte Technik immer noch relativ geringe Pfostenabstände von etwa 2 Metern sowie eine Führung der Platten über die gesamte Höhe von bis zu 3 Metern notwendig.Remedy for this provides, for example, EP-A-0 530 512. Herein is disclosed a disk system in which Do not use plastic sheets with a gap on the butt or in the distance substantially overlapping outside of the support surface are laid, but partially overlapping each other the overlap and the bearing surface on the wearer anchored to the carrier. This allows the required carrier width without affecting the Stability can be roughly halved. Although this especially for wall systems and especially in transparent noise barriers a visually pleasing Impression gives, as the carriers are slim and not more as hitherto clumsy, makes the EP-A-0 530 512 known technique still relatively low post distances from about 2 meters as well as a guide of the plates over the total height of up to 3 meters necessary.

Es hat nun bereits Vorschläge gegeben, wie sowohl der Pfostenabstand als auch der freie Überstand vergrößert werden können. Einen Vorschlag hierzu entnimmt man beispielsweise der DE-A 42 30 786. Die dort offenbarten Lärmschutzwandsegmente weisen einen im wesentlichen rechteckigen Rahmen auf, welcher randseitig in das Profil von 2 senkrechten Tragpfosten einschiebbar und in diesen verriegelbar ist. In den Rahmen selbst, welcher aus 2 vertikalen Rahmenholmen, einem unteren Rahmenholmen sowie einem zweigeteilten oberen horizontalen Rahmenholmen besteht, sind Schallschluckplatten aus Kunststoff eingeschoben und lösbar gehalten. Dabei muß der Rahmen lediglich eine Höhe haben, die nur etwa 2/3 der Höhe der Schallschluckplatte beträgt, so daß ein Überstand von bis zu 50 % realisierbar ist. Obwohl durch den Überstand und die Vergrößerung des Pfostenabstandes auf bis zu 6 Meter die ansonsten durch eine kurze Pfostenfolge bei bekannten Lärmschutzwänden stark beeinträchtigte Sicht erheblich verbessert ist, ist insbesondere der optische Eindruck einer solchen Lärmschutzwand immer noch schwer und drückend. Eine Halterung für eine biegemomentfreie Lagerung von Wand-oder Deckenplatten ist in DE 3927653 beschrieben.There have already been suggestions, as both the Post distance as well as the free projection increased can be. A suggestion for this one takes For example, DE-A 42 30 786. The disclosed there Noise protection wall segments have a substantially rectangular frame on which edge in the profile of 2 vertical support post inserted and in these is lockable. In the frame itself, which from 2 vertical frame spars, a lower frame spars as well a two-part upper horizontal frame spars exists, sound absorption plates are made of plastic inserted and kept detachable. The frame must be only have a height that is only about 2/3 of the height of Sound absorption plate is such that a supernatant of up to is 50% feasible. Although by the supernatant and the increase of the pole distance up to 6 meters the otherwise by a short post sequence in known Noise barriers greatly impaired visibility considerably is improved, in particular the visual impression Such a noise barrier is still difficult and oppressive. A bracket for a bending moment-free storage of Wall or ceiling panels is described in DE 3927653.

Es wäre wünschenswert eine möglichst einfache und allen Anforderungen entsprechende Befestigung für Lärmschutzwände zur Verfügung zu stellen, die noch unauffälliger als die bekannten Konstruktionen ist und ein müheloses Gleiten der Platte durch Längenänderungen ermöglicht. Insbesondere soll der optische Eindruck des Betrachters durch Tragpfosten, Rahmengestelle oder dergleichen nicht beeinträchtigt werden.It would be desirable to have the simplest possible and all Requirements appropriate mounting for noise barriers to provide that even more inconspicuous than that known constructions and allows effortless sliding of the plate by length changes. In particular, the should visual impression of the viewer through support posts, Frame racks or the like not impaired become.

Gelöst werden diese Aufgaben durch ein Lärmschutzwandsegment der Eingangs genannten Art mit dem Merkmal des kennzeichnenden Teiles des Anspruches 1. Eine vorteilhafte Ausführungsform ist Gegenstand des auf Anspruch 1 rückbezogenen Anspruchs.These tasks are solved by a Noise protection wall segment of the type mentioned with the Characteristic of the characterizing part of claim 1. A advantageous embodiment is the subject of Claim 1 back claim.

Dadurch, daß bei einem Lärmschutzwandsegment die Lärmschutzplatte aus Kunststoff gelenkig und punktförmig so gelagert ist, daß eine unter Last resultierende Biegelinie der Platte durch das Befestigungsmittel begleitbar ist, gelingt es auf verblüffend einfache und nicht ohne weiteres vorhersehbare Weise, auf die bislang im Stand der Technik essentiell notwendige direkte Verbindung/Befestigung am Tragpfosten zu verzichten, ohne die Stabilität der Lärmschutzwand zu gefährden. Durch die erfindungsgemäße "indirekte Befestigung" kann besonders vorteilhaft die Anzahl der Tragpfosten durch Vergrößerung des Pfostenabstands deutlich reduziert werden. Die zur Befestigung des erfindungsgemäßen LS-Segments an Tragpfosten in zweckmäßiger Ausgestaltung einzusetzenden Riegel, welche von Tragpfosten zu Tragpfosten verlaufen, dienen zur Abstützung der Befestigungsmittel und beeinträchtigen den optischen Eindruck einer aus LS-Segmenten der Erfindung errichteten Lärmschutzwand (LS-Wand) in keinster Weise negativ. Vielmehr dominiert bei vergrößertem Träger-/Trägerpfosten-Abstand die dadurch gewonnene "optische Leichtigkeit" der gesamten Wand; die von Pfosten zu Pfosten verlaufenden Abstützriegel treten "optisch zurück" und bleiben im Hintergrund.The fact that in a noise barrier segment the Noise protection plate made of plastic hinged and punctiform so is stored that a resulting under load bending line the plate is accompanied by the fastening means, succeeds in amazingly simple and not easy predictable way, to date in the prior art Essentially necessary direct connection / attachment on Carrying post without sacrificing the stability of the Noise protection wall to endanger. By the invention "indirect attachment" can be particularly advantageous the Number of support posts by increasing the Post distance can be significantly reduced. The to Attachment of the LS segment according to the invention Support posts to be used in an expedient embodiment Latches, which run from support posts to support posts, serve to support the fasteners and affect the visual impression of one LS segments of the invention constructed noise barrier (LS wall) in no way negative. Rather dominates at increased support / support post spacing thereby gained "visual lightness" of the entire wall; the step by step from support to support "visually back" and stay in the background.

Dabei ist es besonders hervorzuheben, daß es im Rahmen der Erfindung gelingt, bei üblichen Lärmschutzwandsegmentgrößen von etwa 2 x 3 Metern und Dicken von etwa 20 mm mit 8 punktförmigen Befestigungen eine allen Anforderungen auch unter Last (Eigenlast oder Windlast) genügende Befestigung zu schaffen. Werden die Befestigungsmittel vom Plattenrand etwa 20 cm zur Plattenmitte verschoben angeordnet, so bildet sich in zweckmäßiger Abwandlung der Erfindung eine Biegelinie aus, die es erlaubt, anstelle von 20 mm Plattendicke (Acrylglas) 15 mm zu verwenden, ohne die Stabilität nachteilig zu beeinflussen.It is particularly noteworthy that in the context of Invention succeeds in conventional noise protection wall segment sizes of about 2 x 3 meters and thicknesses of about 20 mm with 8 punctiform fittings also meet all the requirements sufficient under load (dead load or wind load) attachment to accomplish. Be the fasteners from the edge of the plate arranged about 20 cm shifted to the middle of the plate, so forms in an appropriate modification of the invention a Bending line, which allows it instead of 20 mm Plate thickness (acrylic glass) 15 mm to use without the Stability adversely affect.

Darüber hinaus und insbesondere ist auch noch hervorzuheben, daß selbst unter hoher Last und bei relativ spröden Platten ein Bersten oder Brechen der Platten an den Befestigungsmitteln bei der erfindungsgemäßen Konstruktion ausgeschlossen ist. Dadurch, daß die Befestigungsmittel so ausgebildet sind, daß sie die Biegelinie begleiten, ergibt sich eine sehr stabile und sichere Konstellation.In addition, and in particular is also still to emphasize that even under high load and at relative brittle plates bursting or breaking the plates to the Fasteners in the construction according to the invention is excluded. The fact that the fastening means so are formed so that they accompany the bend line results a very stable and secure constellation.

Die erfindungsgemäßen LS-Platten aus Kunststoff sind sogenannte Flächentragwerke. Die Durchbiegung solcher Flächentragwerke ist unter der Voraussetzung, daß die Plattendicke klein zur Flächenabmessung und die Durchbiegung ebenfalls gering ist, grundsätzlich von der Plattensteifigkeit und der Flächenbelastung abhängig.The LS sheets according to the invention are made of plastic so-called surface structures. The deflection of such Tensile structures is provided that the Plate thickness small to the area dimension and the Bend is also low, basically from the Plate stiffness and the surface loading dependent.

"Biegelinien" ergeben sich im Belastungsfall und reflektieren (beschreiben) im allgemeinen die Durchbiegung der Platte in Abhängigkeit von Verkehrslast, Materialeigenschaften und Befestigung."Bend lines" arise in the load case and generally reflect (describe) the deflection the plate depending on traffic load, Material properties and fastening.

Im Rahmen der Erfindung bedeutet ferner, daß eine unter Last resultierende Biegelinie durch das Befestigungsmittel begleitbar ist, daß es bei Beanspruchung der Platte durch eine Verkehrslast nicht zu einem Versagen der Platte durch Bersten oder Brechen kommt.In the context of the invention further means that an under Load resulting bending line through the fastener it can be accompanied, that it is under load of the plate by a traffic load does not cause a failure of the plate Bursting or breaking comes.

Hierbei bedeutet "begleitbar" im einzelnen, daß das erfindungsgemäße Befestigungselement sich parallel zur Biegelinie der Platte ausrichtet und dadurch das Auftreten von Spannungsspitzen, die zum Bruch der Platte führen könnten, verhindert.In this case, "accompanyable" means in detail that the inventive fastener parallel to Bend line of the plate aligns and thereby the occurrence spikes that cause the plate to break could, prevented.

Es ist vorgesehen, daß das Befestigungsmittel einen mit einem Ende am Träger verankerbaren Bolzen aufweist, der mit seinem anderen Ende durch eine in der Platte vorgesehene Ausnehmung sowie wenigstens je ein beiderseits der Plattenaußenflächen in enger Anschmiegung damit angeordnete Scheibenelemente hindurchgreift, wobei in der Ausnehmung ein elastisches Federelement angeordnet ist, dessen Höhe größer als die Dicke der zu befestigenden Platte ist und wobei der Bolzen in den Scheibenelementen kugelig gelagert ist. It is envisaged that the fastening means with a Having an end anchored to the carrier bolt, with its other end by a provided in the plate Recess and at least one each side of the Plate outer surfaces arranged in close fitting with it Disc elements engages, wherein in the recess an elastic spring element is arranged, whose height is greater than the thickness of the plate to be fastened and wherein the bolt is spherical in the disc elements is.

Das elastische Federelement ist vorzugsweise aus Kunststoff und erfüllt im wesentlichen zwei Aufgaben:

  • 1. Es stellt zwischen Platte und Befestigungsteller einen Spalt von ca. 1 mm zur Verfügung und ermöglicht so ein müheloses Gleiten der Platte durch Längenänderungen und verhindert somit, daß die Teller klappern. Das Federelement ist in seiner Höhe so vorzugsweise gewählt, daß es beim Soll-Abstand der Befestigungsteller um etwa 4 mm zusammengedrückt wird, die Teller unter Spannung stehen und dadurch das Klappern verhindern.
  • 2. Das Kunststoffelement verhindert einen direkten Kontakt des Gewindebolzens mit der Lochleibung der LS-Platte, vorzugsweise ®Paraglas-Platte. Bei direktem Kontakt besteht die Gefahr von Spannungsspitzen, die zur Rißbildung führen können.
    • The elastic spring element is preferably made of plastic and essentially fulfills two tasks:
  • 1. It provides a gap of approx. 1 mm between the plate and the mounting plate, thus allowing an effortless sliding of the plate through changes in length and thus preventing the plates from rattling. The spring element is preferably selected in height so that it is compressed at the desired distance of the fastening plate by about 4 mm, the plates are under tension and thereby prevent rattling.
  • 2. The plastic element prevents direct contact of the threaded bolt with the bearing hole of the LS plate, preferably ®Paraglas plate. In direct contact there is a risk of voltage spikes, which can lead to cracking.

    • Die Scheibenelemente weisen jeweils nach außen von der Platte weggerichtete kugelige Senkungen auf, in welche korrespondierende mit dem Bolzen fest verbundene oder verbindbare Kugelkalottenstümpfe eingreifen.The disc elements have each directed outwardly from the plate spherical Reductions on, in which corresponding with the Bolt firmly connected or connectable Intervene Kugelkalottenstümpfe.

    Die im Wechselspiel miteinander befindlichen kugeligen Senkungen und Kugelkalottenstümpfe in den Befestigungstellern bzw. am Fuße des Gewindebolzens und an der Hutmutter ermöglichen eine geringfügige Drehbarkeit der Scheibenelemente oder Teller um die Achse des am Träger verankerbaren Bolzens.The interspersed spherical ones Countersinks and Kugelkalottenstümpfe in the Fasteners or at the foot of the threaded bolt and on the cap nut allow a slight rotation of the Disc elements or plates around the axis of the carrier anchorable bolt.

    Diese "Drehbarkeit" um die Bolzenachse führt zur gelenkigen Lagerung der erfindungsgemäßen LS-Segmente. Die Hutmutter mit angedrehter Kugelkalotte wird im allgemeinen nur soweit, z. B. mit einer Lehre, angezogen, bis sich der oben erwähnte Spalt von 1 mm einstellt. Selbstsichernde Muttern oder Sicherung durch Klebstoff sind bevorzugt.This "rotation" about the pin axis leads to the articulated Storage of the LS segments according to the invention. The hat mother with turned-Kugelkalotte is generally only so far, z. B. with a gauge, tightened until the top mentioned gap of 1 mm sets. Self-locking nuts or adhesive securing is preferred.

    Eine vorteilhafte Abwandlung der Erfindung zeichnet sich dadurch aus, daß die Scheibenelemente um den Bolzen zentriert sind und einen Durchmesser aufweisen, der groß genug ist, um eine Auflage der Elemente auf der jeweiligen Seite der Platte auch bei Ausdehnung oder Schrumpfung der Platte infolge von Temperaturänderungen zu gewährleisten.An advantageous modification of the invention is characterized characterized in that the disc elements around the bolt are centered and have a diameter that is large enough is to have a circulation of items on each one Side of the plate even with expansion or shrinkage of Plate due to temperature changes.

    Hierbei ist die Ausnehmung in der Platte im einfachsten Falle eine Bohrung, deren Durchmesser vorzugsweise so bemessen ist, daß die temperaturbedingten Längenänderungen der Platten möglich sind. Für 2 x 3 m2 Flächen und Acrylglas haben sich Bohrungen mit einem Durchmesser von etwa 40 mm als vollkommen ausreichend erwiesen.In this case, the recess in the plate in the simplest case, a bore whose diameter is preferably such that the temperature-induced changes in length of the plates are possible. For 2 x 3 m 2 surfaces and acrylic glass, holes with a diameter of about 40 mm have been found to be perfectly adequate.

    Der Durchmesser der Scheibenelemente oder Teller sollte grundsätzlich möglichst groß sein, um die Flächenspannung unter Windlast so klein wie möglich zu halten. Aus optischen Gründen ist dagegen ein möglichst kleiner Durchmesser erwünscht. Für 2 x 3 m2 Platten mit Ausnehmungen von 40 mm Durchmesser haben sich Tellerdurchmesser von etwa 70 mm bewährt. The diameter of the disc elements or plates should always be as large as possible in order to keep the surface tension under wind load as small as possible. For optical reasons, however, the smallest possible diameter is desired. For 2 x 3 m 2 plates with recesses of 40 mm diameter plate diameter of about 70 mm have proven.

    Nachfolgend wird die Erfindung anhand von Ausführungsbeispielen unter Bezugnahme auf die beigefügte Figur eingehender erläutert.The invention is based on Embodiments with reference to the attached Figure explained in more detail.

    Die Figur zeigt im Querschnitt eine Ausführungsform eines erfindungsgemäßen LS-Segments mit LS-Platte (teilweise weggebrochen), Befestigungsmittel und Trägerelement (Riegel), ebenfalls teilweise weggebrochen.The figure shows in cross section an embodiment of a LS segment according to the invention with LS plate (partially broken away), fastening means and carrier element (Bar), also partly broken off.

    In der Figur bezeichnet die Ziffer 1 ein erfindungsgemäßes Lärmschutzwandsegment, das aus Vereinfachungsgründen nur teilweise im Ausschnitt dargestellt ist.In the figure, the numeral 1 denotes an inventive Noise protection wall segment, the sake of simplification only partially shown in the clipping.

    Das Lärmschutzwandsegment 1 besteht im wesentlichen aus der Lärmschutzplatte 2 sowie dem Befestigungsmittel 3. Das Befestigungsmittel 3 dient zur Verankerung der Platte 2 am Riegel 11, welcher beispielsweise mehrere nicht einzeln dargestellte Pfosten miteinander verbinden kann.The noise barrier wall segment 1 consists essentially of the Noise protection plate 2 and the fastener 3. The Fastener 3 is used to anchor the plate 2 am Latch 11, which for example several not individually can connect shown posts together.

    Die Platte 2 weist im gezeigten Beispiel senkrecht zur Flächenebene der Platte verlaufende Nylonfäden 2a auf, welche die Entstehung von freien Bruchstücken bei Zerstörung der Platte durch Unfall u. dgl. verhindern.The plate 2 has in the example shown perpendicular to Surface plane of the plate extending nylon threads 2a, which contributes to the formation of free fragments Destruction of the plate by accident u. Like. Prevent.

    Die Platte 2 weist eine Ausnehmung 4 auf, i. e. im einfachsten Fall eine kreisförmige Bohrung. Durch die Bohrung 4 hindurch ragt ein Bolzen 5. Der Bolzen 5 ist mit seinem einen Ende, welches ein Gewinde aufweisen kann, im Riegel 11 befestigt. Das andere Ende des Bolzens 5 greift sowohl durch die Bohrung 4 als auch das Federelement 9 hindurch, welches in der Bohrung 4 angeordnet ist. Die Höhe der elastischen Rundfeder 9 ist dabei geringfügig größer als die Dicke der Platte 2. The plate 2 has a recess 4, i. e. in the the simplest case is a circular hole. By the Bore 4 passes through a bolt 5. The bolt 5 is with its one end, which may have a thread in the Latch 11 attached. The other end of the bolt 5 engages both through the bore 4 and the spring element. 9 through which is arranged in the bore 4. The height the elastic round spring 9 is slightly larger as the thickness of the plate 2.

    Neben der elastischen Feder 9 greift der Bolzen 5 auch noch durch einen ersten Befestigungsteller 8 sowie einen zweiten Befestigungsteller 8, welcher dem Riegel 11 fern ist.In addition to the elastic spring 9, the bolt 5 also still engages by a first attachment plate 8 and a second Fastener 8, which is the bolt 11 away.

    Der Durchmesser der Befestigungsteller 8 ist im gezeigten Beispiel etwa 7/4 vom Durchmesser der Bohrung 4. Zwischen zweitem Befestigungsteller 8 und Platte 2 besteht aufgrund der Plattendicke sowie der Höhe der Feder 9 ein dünner Spalt.The diameter of the attachment plate 8 is shown in FIG Example about 7/4 of the diameter of the hole 4. Between second mounting plate 8 and plate 2 is due the plate thickness and the height of the spring 9 thinner Gap.

    Der erste Befestigungsteller 8 weist an seiner dem Riegel zugewandten Seite eine kugelige Senkung auf. In dieser lagert der Bolzen mit einem angedrehten Kugelkalottenstumpf 6. Auch der zweite Befestigungsteller weist eine kugelige Senkung auf, allerdings an der dem Riegel abgewandten Seite.The first attachment plate 8 has at its the latch facing side on a spherical depression. In this supports the bolt with a grooved Kugelkalottenstumpf 6. The second mounting plate has a spherical Lowered, but on the side facing away from the bolt Page.

    In dieser Senkung lagert eine Hutmutter 10 mit Konus, welche auf ein Gewinde 7 des Bolzens 5 greift.In this countersink a cap nut 10 with cone, which engages a thread 7 of the bolt 5.

    Bolzen 5 mit Kugelkalottenstumpf 6 und Gewinde 7 bilden zusammen ein Distanzstück mit Kugelkalotte, welches durch Anziehen der Hutmutter 10 fixiert wird. Durch den Spalt zwischen zweitem Befestigungsteller 8 und Platte 2 sowie das Zusammenwirken von kugeligen Senkungen in den Tellern 8 und in ihnen gelagerten Kalottenstümpfen entsteht eine gelenkige und punktförmige Lagerung, bei welcher das Befestigungsmittel 3 einer unter Last in der Platte 2 resultierenden Biegelinie folgen kann. Bolt 5 with Kugelkalottenstumpf 6 and thread 7 form together with a spacer with spherical cap, which by Tighten the cap nut 10 is fixed. Through the gap between the second mounting plate 8 and plate 2 as well the interaction of spherical depressions in the plates 8 and in them stored Kalottenstümpfen one creates articulated and point-shaped storage, in which the Fastener 3 a under load in the plate. 2 resulting bending line can follow.
