Abstract

The mounting unit has a connection unit provided between a partition wall e.g. fire-protection panel, and a brickwork. The connection unit has a U-shaped profile (4.1) including blades (4.1.1) whose sides are fit at the surfaces of the wall. A spring part of the connection unit is fixed at the U-shaped profile to exert a force against the surface of the brickwork. The profile and the spring part are made of sheet metal. The spring part is elastically stretched at the base of the U-shaped profile during the mounting and demounting of the mounting unit.

Description

Die Erfindung betrifft eine Methode zum Befestigen von mehrschichtigen Trennwandelementen in einem Gebäude. Sie ist insbesondere gut dazu geeignet sogenannte "rahmenlose" Trennwandelemente aus Brandschutzglas demontierbar an umgebendem Mauerwerk zu befestigten.The invention relates to a method for securing multi-layered partition elements in a building. It is particularly well suited to so-called "frameless" partition wall elements made of fire-resistant glass to be attached demountable to surrounding masonry.

Unter "rahmenlosen" Trennwandelementen wird hier verstanden, daß ein Wandflächenelement in unverbautem Zustand nicht durch einen Rahmen eingefaßt ist, sondern daß die Stirnseiten seines flächigen Materials frei liegen. Eine Art Einfassung des Wandflächenelements wird erst nach dem Aufstellen als Verbindung undBy "frameless" partition elements is meant here that a wall surface element is not enclosed by a frame in the uninstalled state, but that the end faces of its sheet material are exposed. A kind of enclosure of the wall surface element is only after setting up as a connection and

Abdichtung zum angrenzenden Mauerwerk gebildet, wobei diese Einfassung in der Normalen auf das Wandflächenelement möglichst nicht über dieses vorstehen, sondern bündig damit abschließen soll. Aus optischen Gründen sollte der Rand des Flächenelements möglichst nahe am umgebenden Mauerwerk verlaufen, die beschriebene verbindende und dichtende Einfassung also möglichst dünn sein. Das sollte auch unter der Bedingung erreicht werden, daß die Verbindung zwischen Wandflächenelement und umgebenden Mauerwerk zwar mechanisch sicher und fest aber dennoch soweit lösbar sein soll, daß das Wandflächenelement ohne Zerstörung vom Mauerwerk gelöst und falls gewünscht an einer anderen Stelle wieder damit verbunden werden kann.Formed seal to the adjacent masonry, this enclosure in the normal on the wall surface element as possible not project beyond this, but should flush with it. For optical reasons, the edge of the surface element should be as close as possible to the surrounding masonry, the connecting and sealing enclosure described so be as thin as possible. This should also be achieved under the condition that the connection between the wall surface element and the surrounding masonry should be mechanically safe and strong but yet so far soluble that the wall surface element can be solved without destruction of the masonry and if desired at another location again connected.

Bei der Bauweise entsprechend der DE 19957026 A1 wird das Flächenelement in einen vorbereiteten Rahmen gestellt, der eine Anschlagfläche gegen die Stirnseiten des Flächenelementes und gegen den daran angrenzenden Bereich einer Seitenfläche bildet. Danach werden am Rahmen Leisten befestigt, welche an der zweiten Seite des Flächenelementes einen Anschlag bilden. Diese Befestigungsart ist einfach und sicher herstellbar, hat aber den Nachteil, daß die Einfassung in der auf das Flächenelement normalen Richtung beträchtlich über dieses hinausragt, und somit einen in manchen Fällen, vor allem aus optischen Gründen unerwünschten Rahmen bildet.In the construction according to the DE 19957026 A1 the surface element is placed in a prepared frame which forms a stop surface against the end faces of the surface element and against the adjoining region of a side surface. Thereafter, strips are attached to the frame, which form a stop on the second side of the surface element. This type of fastening is simple and safe to produce, but has the disadvantage that the enclosure in the direction normal to the surface element extends considerably beyond this, and thus forms an undesirable in some cases, especially for optical reasons frame.

Entsprechend der DE 696 11 396 T2 (aus der EP 745750 B1 hervorgegangen) ist eine Befestigungsmöglichkeit für Isolierglasscheiben ersichtlich, wobei ein Verbindungsteil einerseits am Scheibenrand zwischen die beiden Einzelscheiben des Isolierglases reicht und daran mittels Verklebung befestigt ist, anderseits mit einem dazu in der Glasebene zumindest einmal beweglichen Teil in eine Vertiefung an dem die Scheibe umgebenden Rahmen eingreift und somit die Scheibe gegen Bewegung normal zu ihrer Ebene sichert. Mit Hilfe dieser Bauweise ist es möglich ein Trennwandelement "rahmenlos" am umgebenden Mauerwerk zu befestigen. Nachteilig daran ist, daß der Verbindungsteil vor der Montage des Flächenelementes mit diesem verklebt werden muß.According to the DE 696 11 396 T2 (from the EP 745750 B1 emerged) is a mounting option for insulating glass panes, with a connecting part on the one hand at the edge of the disk between the two individual panes of the insulating glass and is attached thereto by gluing, on the other hand with a thereto in the glass plane at least once movable part engages in a recess on the frame surrounding the disc and thus secures the disc against movement normal to its plane. With the help of this design, it is possible to attach a partition element "frameless" to the surrounding masonry. The disadvantage of this is that the connecting part must be glued before assembly of the surface element with this.

Die Bauweise ist in der beschriebenen Form nicht anwendbar, wenn die zu montierende Trennwand einen wirksamen Brandschutz bieten soll. Es finden sich auch kein Hinweise wie sie für diesen Anwendungsfall abgeändert werden sollte.The design is not applicable in the described form, if the partition to be mounted should provide effective fire protection. There are also no indications as to how they should be modified for this application.

Der Erfinder hat sich die Aufgabe gestellt, eine Methode für eine rahmenlose, demontierbare, einfach herzustellende Befestigung von mehrschichtigen Trennwandelementen an einem umgebenden Mauerwerk in einem Gebäude zu entwickeln. Es sollen damit auch Anforderungen an Brandschutzwände erfüllbar sein und es sollen keine Befestigungsteile mit den Trennwandelemente verklebt werden müssen.The inventor has set himself the task of developing a method for a frameless, demountable, easy to produce attachment of multi-layered partition elements to a surrounding masonry in a building. It should also be met requirements for fire walls and it should not be glued hardware with the partition elements.

Zum Lösen der Aufgabe wird vorgesehen, daß in dem das Trennwandelement umgebenden Mauerwerk in der Ebene des Trennwandelementes liegende, eine parallel zu deren Rändern verlaufende Schiene mit etwa U-förmiger Querschnittsform derart eingesetzt ist, daß sie eine das Trennwandelement umfassende nutartige Vertiefung im Mauerwerk bildet. Zwischen Randbereichen des Trennwandelementes und der parallel dazu im Mauerwerk verlaufenden Schiene, sind mehrere gleichartige Verbindungsteile angeordnet. Ein derartiges Verbindungsteil besteht aus einem U-Profilstück, welches sich parallel zum Randbereich des Trennwandelementes erstreckt, mit seinen Schenkeln zwischen die äußeren Flächenelemente des Trennwandelementes ragt und mit den Flanken der Schenkel an Flächenelementen des Trennwandelementes anliegt. Von der den Schenkeln abgewandten Seite der Basis des U-Profilstücks ragt ein damit verbundener Federteil in die am Mauerwerk verlaufende nutartige Vertiefung und liegt unter elastischer Vorspannung am Boden oder an den Flanken dieser nutartigen Vertiefung an. Für den Montagevorgang und erforderlichenfalls auch den Vorgang der Demontage kann dieser Federteil mit einer Klammer an die Basis des U-Profilstücks gespannt werden.To solve the problem, it is provided that in which the partition wall element surrounding masonry in the plane of the partition element lying, a parallel to the edges extending rail is used with approximately U-shaped cross-sectional shape such that it forms a partition wall element comprehensive groove-like depression in the masonry. Between edge regions of the partition wall element and parallel to the masonry extending rail, a plurality of identical connecting parts are arranged. Such a connecting part consists of a U-profile piece which extends parallel to the edge region of the partition wall element, projects with its legs between the outer surface elements of the partition wall element and rests with the flanks of the legs of surface elements of the partition wall element. From the side facing away from the legs of the base of the U-shaped piece protrudes a spring member connected thereto in the masonry groove-like depression and is under elastic bias to the bottom or on the flanks of this groove-like depression. For the assembly process and, if necessary, the process of disassembly of this spring member can be clamped with a clamp to the base of the U-profile piece.

Bei dem dargestellten Beispiel ist das Trennwandelement eine Brandschutzscheibe 2, welches aus mindestens drei Einzelscheiben besteht. Die beiden äußeren Einzelscheiben 2.1 werden an der mittleren Einzelscheibe 2.2 durch nahe am Scheibenrand umlaufende Verbindungselemente 2.3 in einem Abstand 2.4 gehalten.In the example shown, the partition wall element is a fire protection pane 2, which consists of at least three individual panes. The two outer ones Single disks 2.1 are held at the middle individual disk 2.2 by close to the disk edge surrounding fasteners 2.3 at a distance 2.4.

Zur Montage der dargestellten Brandschutzscheibe 2 sind folgende Arbeitsschritte erforderlich:

  • Befestigen einer Unterlageschiene 11 am unteren umgebenden Mauerwerk 1.
  • Befestigen des Nutprofils 3 am seitlichen und oberen umgebenden Mauerwerk.
  • Verputzen des umgebenden Mauerwerks und Anbringen des Bodenbelages, sodaß Unterlageschiene 11 und Nutprofil 3 bündig damit abschließen.
  • Anbringen der aus einem flachen U-Profil gebildeten unteren Halteschiene 9 an der Unterlageschiene 11. Die an den der Halteschiene 9 drehbar angebrachten länglichen Laschen 10 sind dabei mit ihrer Längsrichtung parallel zur Halteschiene gedreht.
  • Einlegen der Brandschutzplatte 8 in die Halteschiene 9.
  • Anbringen der selbstklebenden, im Brandfall aufquellenden Brandschutzstreifen 6.1 und 6.2 am Rand der Innenflächen der äußeren Scheiben 2.1 bzw. in den Boden des Nutprofils 3.
  • Aufstecken von Verbindungsteilen 4 an den oberen Scheibenrand und jenen seitlichen Scheibenrand, welcher mit dem umliegenden Mauerwerk verbunden werden soll.
The following work steps are required for mounting the illustrated fire protection pane 2:
  • Attaching a support rail 11 at the lower surrounding masonry. 1
  • Attaching the groove profile 3 on the lateral and upper surrounding masonry.
  • Plastering the surrounding masonry and attaching the floor covering, so that support rail 11 and groove profile 3 flush with it.
  • Attaching the formed from a flat U-profile lower support rail 9 on the support rail 11. The rotatably attached to the support rail 9 elongated tabs 10 are rotated with its longitudinal direction parallel to the support rail.
  • Inserting the fire protection plate 8 in the retaining rail. 9
  • Attaching the self-adhesive, in case of fire swelling fire protection strips 6.1 and 6.2 at the edge of the inner surfaces of the outer discs 2.1 or in the bottom of the groove profile. 3
  • Attaching connecting parts 4 to the upper edge of the disc and those lateral edge of the disc, which is to be connected to the surrounding masonry.

Das U-Profilstück 4.1 jedes Verbindungsteils 4 erstreckt sich mit seiner Längsrichtung in Richtung des Scheibenrandes, umfaßt mit seinen Schenkeln 4.1.1 den Rand der mittleren Einzelscheibe 2.2 und wird daran über eine leichteThe U-profile piece 4.1 of each connecting part 4 extends with its longitudinal direction in the direction of the disc edge, comprising with its legs 4.1.1 the edge of the middle single disc 2.2 and is about a slight

Preßpassung (direkt oder über eine Zwischenschicht aus einem weichen Material), oder durch Haftung unter Mitwirkung einer pastösen Zwischenschicht, beispielsweise einer Silikonmasse, gehalten.Press fit (directly or via an intermediate layer of a soft material), or by adhesion with the participation of a pasty intermediate layer, such as a silicone composition held.

Der als Blattfeder ausgeführte Federteil 4.2 des Verbindungsteils ist an das U-Profilstück 4.1 gebogen und wird in dieser Stellung durch den am U-Profilstück linear verschiebbaren Fixierteil 4.3 gehalten.

  • Die Brandschutzscheibe 2 mit der unteren Stirnfläche der mittleren Einzelscheibe 2.2 auf die Brandschutzplatte 8 in der unteren Halteschiene 9 stellen.
  • Die Brandschutzscheibe 2 in Längsrichtung der unteren Halteschiene passend linear verschieben und um diese untere Lage herum in die richtige (vertikale) Ausrichtung drehen.
  • Den Fixierteil 4.3 des Verbindungsteiles so verschieben, daß der Federteil 4.2 "befreit" wird und sich mit seinem nicht am Profilstück 4 befestigten Ende in die durch das Nutprofil 3 am anliegenden Mauerwerk gebildete Nut hineinbewegt und an den Begrenzungen der Querschnittsfläche dieser Nut unter elastischer Vorspannung anliegt. Die Bewegung des Federteils erfolgt in der Ebene der Scheibe; normal dazu ist der Federteil starr. Die Brandschutzscheibe ist damit gegen Bewegung normal zu Ihrer Ebene gesichert.
  • Hochdrehen der längüchen Laschen 10 an der unteren Halteschiene 9, sodaß sie sich in die Scheibenzwischenräume 2.4 der Brandschutzscheibe erstrecken und somit auch am unteren Rand Bewegung der Brandschutzscheibe 2 normal zu ihrer Ebene verhindern.
  • Einbringen von Mineralwolle (in Form von Schnüren) in den Hohlraum zwischen Mauerwerk (1) und Stirnflächen der Brandschutzscheibe (2).
  • Versiegeln der Spalte zwischen den Stirnflächen der äußeren Einzelscheiben 2.2 und dem umgebenden Mauerwerk 1 durch Auftragen einer pastösen Masse auf Silikon- oder Acrylbasis, welche zu einem gummielastischen Dichtprofil 7 aushärtet.
The executed as a leaf spring spring part 4.2 of the connecting part is bent to the U-profile piece 4.1 and is held in this position by the linearly displaceable on the U-shaped piece fixing part 4.3.
  • Place the fire protection pane 2 with the lower end face of the middle single pane 2.2 on the fire protection plate 8 in the lower holding rail 9.
  • Move the firing screen 2 in the longitudinal direction of the lower support rail to fit linearly and rotate it around this lower layer in the correct (vertical) orientation.
  • Move the fixing part 4.3 of the connecting part so that the spring part 4.2 is "released" and moved with its not attached to the profile piece 4 end in the groove formed by the groove 3 on adjacent masonry groove and rests against the boundaries of the cross-sectional area of this groove under elastic bias , The movement of the spring part takes place in the plane of the disc; Normally, the spring part is rigid. The fire screen is thus secured against movement normal to your plane.
  • Turning the longitudinal tabs 10 on the lower support rail 9, so that they extend into the space between the discs 2.4 of the fire protection and thus also prevent movement of the fire panel 2 normal to its level at the bottom.
  • Introducing mineral wool (in the form of strings) in the cavity between the masonry (1) and end faces of the fire protection pane (2).
  • Sealing the gap between the end faces of the outer individual discs 2.2 and the surrounding masonry 1 by applying a pasty mass on silicone or acrylic, which cures to a rubber-elastic sealing profile 7.

Es ist vorteilhaft, die einzelnen Bestandteile des Verbindungsteils aus Blech, vorzugsweise Stahlblech herzustellen. Durch diese Materialwahl werden gegenüber Kunststoff die Vorteile erreicht, daß die erforderliche Festigkeit auch bei der im Brandfall auftretenden Erhitzung gegeben ist, und daß die für die normale Funktion erforderliche elastische Vorspannung des Federteiles 4.2 problemlos über die Lebensdauer des Bauwerks erhalten bleibt.It is advantageous to produce the individual components of the connecting part of sheet metal, preferably steel sheet. By this choice of material advantages over plastic are achieved that the required strength is given even in the heating occurring in case of fire, and that the required for the normal function elastic bias of the spring member 4.2 is easily maintained over the life of the building.

Der Verbindungsteil 4 liegt an der Brandschutzscheibe 2 nur an der mittleren Einzelscheibe 2.2 und nicht an den äußeren Einzelscheiben 2.1 an. Damit wird verhindert, daß im Brandfall über den Verbindungsteil gefährliche Wärmeübertragung zwischen verschiedenen Einzelscheiben stattfindet.The connecting part 4 rests against the fire protection pane 2 only at the middle individual pane 2.2 and not at the outer individual panes 2.1. This prevents dangerous heat transfer between different individual panes taking place in the event of fire via the connecting part.

Die Dicke der Schenkel 4.1.1 des U-Profilstücks 4.1 des Verbindungsteils 4 ist um so viel geringer als die Breite des Abstandes 2.4 zwischen der mittleren Einzelscheibe 2.2 und den äußeren Einzelscheiben 2.1, daß im verbleibenden Spalt noch der Brandschutzstreifen 6.1 durchgeführt werden kann. Damit wird erreicht, daß der Brandschutzstreifen auch im Bereich der Verbindungsstückes 4 im Brandfall seine sinngemäße Aufgabe, nämlich Abdichten und Wärme dämmen erfüllen kann.The thickness of the legs 4.1.1 of the U-profile piece 4.1 of the connecting part 4 is so much smaller than the width of the distance 2.4 between the middle single disc 2.2 and the outer individual slices 2.1, that in the remaining gap still the fire protection strip 6.1 can be performed. This ensures that the fire protection strip in the region of the connecting piece 4 in the event of fire his meaningful task, namely dams and heat can meet.

Der Fixierteil 4.3 besteht aus einem kurzen Profilteil mit etwa U-förmiger Querschnittsfläche, wobei die freien Enden 4.3.3 der beiden Schenkel 4.3.2 etwas zueinander gebogen sind. Er ist bezüglich Profilrichtung und Profilöffnung so angeordnet wie das U-Profilstück 4.1, und er ist so groß ausgelegt, daß er das U-Profilstück 4.1 in dieser Lage umfassen kann. In der Querschnittsansicht sind seine Schenkel 4.3.2 um so viel Länger als die Schenkel 4.1.1 des U-Profilstücks 4.1, daß dann wenn die eingebogenen Schenkelenden 4.3.3 an den Schenkelenden des U-Profilstücks 4.1 anliegen, die Basis des U einen Abstand zur Basis der U-Querschnittsfläche des U-Profilstücks 4.1 einnimmt. Dieser Abstand ist zumindest geringfügig größer als die Blechstärke des als Blattfeder ausgeführten Federteils 4.2. Damit kann der in entspanntem Zustand vom U-Profilstück 4.1 abstehenden Teil des Federteils 4.2 unter elastischer Vorspannung am U-Profilstück 4.1 gehalten werden, indem er zuerst an dieses gedrückt wird und indem dann der Fixierteil am U-Profilstück so verschoben wird, daß er die Querschnittsfläche des angedrückten Federteils mit umfaßt. Zum Lösen des Federteils muß der Fixierteil wiederum aus dieser Stellung weggeschoben werden können. Um das Lösen und Fixieren des Federteils aus der anliegenden Stellung bzw. in die anliegende Stellung auch dann zu ermöglichen, wenn der Verbindungsteil an der Brandschutzscheibe und diese an der Wand angeordnet ist, ist der Fixierteil 4.3 mit stirnseitig von der Basis seines U-Profilteils aufgebogenen Laschen 4.3.1 versehen. Im spitzen Winkel zwischen diesen Laschen und der Basis des U-Profilteils kann man gut mit der Spitze eines Schraubenziehers ansetzen und den Fixierteil 4.3 entlang des U-Profilstücks 4.1 verschieben.The fixing part 4.3 consists of a short profile part with approximately U-shaped cross-sectional area, wherein the free ends 4.3.3 of the two legs 4.3.2 are slightly bent to each other. He is with respect to profile direction and profile opening arranged as the U-profile piece 4.1, and it is designed so large that it can include the U-profile piece 4.1 in this position. In the cross-sectional view its legs 4.3.2 are so much longer than the legs 4.1.1 of the U-profile piece 4.1, that when the bent leg ends 4.3.3 rest against the leg ends of the U-profile piece 4.1, the base of the U a distance to the base of the U-sectional area of the U-profile piece 4.1 occupies. This distance is at least slightly greater than the sheet thickness of the designed as a leaf spring spring part 4.2. Thus, the projecting in the relaxed state of the U-shaped piece 4.1 part of the spring member 4.2 can be kept under elastic bias on the U-profile piece 4.1 by first pressed on this and then by the fixing part on the U-profile piece is moved so that he Cross-sectional area of the pressed-on spring part includes. To release the spring part, the fixing part must again be able to be pushed away from this position. In order to enable the release and fixing of the spring member from the adjacent position or in the applied position, even if the connecting part is arranged on the fire protection screen and this on the wall, the fixing part 4.3 is bent with the front side of the base of its U-profile part Tabs 4.3.1 provided. in the acute angle between these tabs and the base of the U-profile part can be done well with the tip of a screwdriver and move the fixing part 4.3 along the U-profile piece 4.1.

Durch richtige Dimensionierung des mit der Scheibe in einer leichten Preßpassung in Kontakt stehenden U-Profilstücks 4.1 kann dessen Haltefunktion an der Scheibe unempfindlich gegen Fertigungstoleranzen der Breiten der einzelnen verwendeten Teile bereitgestellt werden. Durch Verwendung eines entsprechend dünnen Bleches wird es nämlich möglich, die Schenkel 4.1.1 des U-Profils unter elastischer Verformung in einem ausreichend weiten Bereich bis zur passenden Scheibendicke auseinanderzuspreizen, ohne daß dabei für die Scheiben gefährlich große Kräfte pro Länge auftreten. Damit dennoch die erforderlichen Haltekräfte aufgebracht werden können, muß das Profilstück nur ausreichend lang gestaltet werden. Diesbezüglich eine gute Dimensionierung zu treffen, entsprechend welcher auch vorteilhafte Formdetails wie beispielsweise eine leichte Krümmung der beiden Schenkel oder in entspanntem Zustand eine nicht zueinander parallele sondern aufeinander zu weisende Winkelausrichtung berücksichtigt ist, gehört zur normalen fachmännischen Tätigkeit von Konstrukteuren.By properly dimensioning the U-profile piece 4.1 in contact with the disc in a slight interference fit, its holding function on the disc can be made insensitive to manufacturing tolerances of the widths of the individual parts used. By using a correspondingly thin sheet, it is namely possible to spread apart the legs 4.1.1 of the U-profile under elastic deformation in a sufficiently wide range to the appropriate pane thickness, without causing the discs dangerous large forces per length occur. Thus, the necessary holding forces can be applied, the profile piece must be designed only long enough. In this regard, a good dimensioning to meet, according to which also advantageous shape details such as a slight curvature of the two legs or in a relaxed state is considered not parallel to each other but facing each other angular orientation is part of the normal professional activity of designers.

Vor allem dann wenn die mögliche Wärmeübertragung zwischen verschiedenen Einzelflächen eines Trennwandelementes kein Problem ist, kann das U-Profilstück des Verbindungsteils auch mit der Außenseite seiner beiden Schenkel an jeweils einer Einzelfläche anliegen.Especially if the possible heat transfer between different individual surfaces of a partition wall element is not a problem, the U-shaped piece of the connecting part can also rest with the outside of its two legs on a single surface.

Bei Anwendungsfällen bei denen eine höhere Punktlast am Trennwandelement keinen wesentlichen Nachteil mit sich bringt, kann der Verbindungsteil auch komplementär zu dem gezeigten Beispiel eingesetzt werden, nämlich so, daß er mit seinem U-Profilteil am umgebenden Mauerwerk anliegt und mit dem Federteil in einen Zwischenraum am Trennwandelement eingreift.In applications where a higher point load on the partition wall element brings no significant disadvantage, the connecting part can also be used complementary to the example shown, namely so that it rests with its U-profile part of the surrounding masonry and with the spring member in a space on Partition wall element engages.

Anstatt einer Vertiefung am umgebenden Mauerwerk wäre es auch möglich eine Erhöhung, im einfachsten Fall in Form eines aus der Mauerfläche herausragenden Profilsteges anzubringen und an diesem die Verbindung zum Trennwandelement angreifen zu lassen. Am Beispiel des dargestellten Verbindungsteils müßte dann der als breite Blattfeder gezeigte Federteil 4.2 gabelförmig ausgebildet werden, oder durch zwei in einem Abstand parallel zueinander angeordnete schmälere Blattfedern ersetzt werden, von denen dann je eine an einer Seite dieses Steges anläge.Instead of a recess on the surrounding masonry, it would also be possible to increase, in the simplest case in the form of a protruding from the wall surface profile web and to let it attack the connection to the partition wall element. Using the example of the connecting part shown, the spring part 4.2, which is shown as a wide leaf spring, would then have to be fork-shaped, or be replaced by two narrower leaf springs arranged at a distance parallel to one another, one of which then being abutted on one side of this web.

Der als "U-Profilstück" (4.1) bezeichnete Basisteil des Verbindungsteils 1 ist im einfachsten und auch sehr optimalen Fall tatsächlich als U-Profil ausgeführt. Entscheidend für die Funktion ist, daß er eine durch zwei Flanken begrenzte Nut bildet, deren Öffnungsfläche in der zur Ebene des Flächenelementes normal liegenden Richtung eine Ausdehnung hat. Wie die Flanken und der zwangsläufig zur Verbindung dieser Flanken erforderliche Steg darüber hinaus ausgeführt sind, ist für die prinzipielle Funktion nicht entscheidend.The "U-profile piece" (4.1) designated base part of the connecting part 1 is actually executed in the simplest and very optimal case as a U-profile. Decisive for the function is that it forms a groove bounded by two flanks whose opening surface has an extension in the direction normal to the plane of the surface element. The way in which the flanks and the bridge which is necessarily required for the connection of these flanks are, moreover, not decisive for the basic function.
