Description
Die Erfindung geht von einer bei einem Gleitbogenausbau aus geflanschten Rinnenprofilen bekannten Verbindung aus, bei welcher die Flansche durch haken- oder bügelartige Spannkörper zusammengehalten sind, und kennzeichnet sich dadurch, daß ein jedem Spannkörper zugeordnetes Klemmstück mit einem klauenartigen Ansatz in eine Vertiefung des Flansches des Außenprofils eingreift und mit einem Verlängerungsansatz gegen die Seitenflächen der Profilflansche oder eines Spannkörpers anliegt. Die Verbindung nach der Erfindung ermöglicht ein besseres Verspannen der Profile als die bisher bekannten hakenartigen Verbindungsmittel und verhindert vor allen Dingen ein Verkanten der Verbindungsschrauben und deren seitliches Durchbiegen.The invention is based on a flanged in a sliding arch construction Channel profiles known connection, in which the flanges by hook or Stirrup-like clamping bodies are held together, and is characterized in that a clamping piece assigned to each clamping body with a claw-like projection in a recess in the flange of the outer profile engages and with an extension approach against the side surfaces of the profile flanges or a clamping body. the Connection according to the invention allows a better clamping of the profiles than the previously known hook-like connecting means and above all prevents tilting of the connecting screws and their lateral bending.
In der Zeichnung ist die Erfindung an einem Ausführungsbeispiel in Seitenansicht dargestellt. Es sind mit a und b die Profilböden, mit c und d die Profilflansche, mit e und f die als Spannkörper dienenden Hakenschrauben, mit g und h die Klemmstücke und mit . i und k die an diesen sitzenden klauenartigen Ansätze bezeichnet, welche in rillenartige Vertiefungen der Flansche des Außenprofils eingreifen.In the drawing, the invention is shown in an exemplary embodiment in a side view. With a and b the profile bases, with c and d the profile flanges, with e and f the hook bolts that serve as clamping bodies, with g and h the clamping pieces and with. i and k denote the claw-like attachments seated on these, which engage in groove-like depressions in the flanges of the outer profile.
Um die Klemmstücke g und h am Verkanten zu hindern und gegen Herauswürgen der Ansätze i und k aus den Rillen o der Flansche c zu schützen, erhalten sie Verlängerungsansätze m, n, welche sich möglichst weitausholend gegen Teile der Spannkörper oder der Profile stützen können. Die Ansätze m, n schützen gleichzeitig die Bolzen gegen seitliches Durchbiegen beim Einschieben der Profile, wenn sie die Bolzen zweckmäßig wie ein Rohr umfassen. Diese Anordnung kann, wie die Abbildung zeigt, so ausgeführt sein, daß der Ansatz von seinem möglichst breiten Fuß ausgehend nach außen zu ansteigend verläuft; der Ansatz kann aber auch, wie strichpunktiert gezeigt ist, nach den Flanschen zu ansteigend verlaufen.In order to prevent the clamping pieces g and h from tilting and to protect them against strangulation of the approaches i and k from the grooves o of the flanges c, they receive extension approaches m, n, which can be supported as far as possible against parts of the clamping body or the profiles. At the same time, the approaches m, n protect the bolts against bending sideways when the profiles are inserted, if they appropriately enclose the bolts like a tube. This arrangement can, as the figure shows, be designed so that the approach extends from its foot as wide as possible to the outside to rise; however, the approach can also, as is shown by dash-dotted lines, run to ascending after the flanges.
Wie gestrichelt angedeutet, können an Stelle der Hakenspannkörper auch bügelförmige Spannkörper verwendet werden, die die Profile übergreifen.As indicated by dashed lines, instead of the hook clamping body bow-shaped clamping bodies can also be used, which overlap the profiles.
Die Erfindung ist in der Hauptsache für solche Verbindungen gedacht, bei welchen die rinnenförmigen Profilkörper mondsichelartigen Querschnitt besitzen. Sie läßt sich mit Vorteil jedoch auch für jeden anderen nachgiebigen Grubenausbaurahmen aus geflanschten Rinnenprofilen verwenden.The invention is mainly intended for such compounds in which the channel-shaped profile bodies have a crescent-shaped cross-section. However, it can also be used with advantage for any other flexible pit support frame use made of flanged gutter profiles.
