Description
DEUTSCHESGERMAN
Der Ausgleich von Längentoleranzen, insbesondere bei Gittermasten (Rohrmasten) wurde in der Weise vorgenommen, daß man für den Anschluß der Zugstäbe am Knotenblech besondere Laschen vorsah mit verschieden weitem Lochabstand und nun zur Montage der Maste jeweils eine Anzahl von Laschen mit verschiedenem Lochabstand bereit hielt, um sich dann bei der Montage die passendenLaschen herauszusuchen.The compensation of length tolerances, especially with lattice masts (tubular masts) was done in the way made that special tabs were provided for connecting the tension rods to the gusset plate hole spacing of different widths and now each with a number of brackets for mounting the masts with different hole spacing in order to then choose the appropriate tabs during assembly.
Ferner ist es bekannt, einen Ausgleich der Längentoleranz mittels Exzenterscheiben vorzunehmen, wobei in die entsprechend große Bohrung des Abschlußbleches eine zylinderförmige Scheibe eingelegt wird, deren den Schraubenschaft aufnehmende Bohrung exzentrisch angebracht ist. Durch Drehen der Scheibe werden die Schraubenlöcher zur Deckung gebracht. Die exzentrisch angeordnete Bohrung in der Scheibe ist so ausgeführt, daß sie sich beim Drehen der hindurchgesteckten Schraube mitdreht, also es möglich macht, den Stab vor dem endgültigen Anziehen der Schraube zu spannen. Da die Zugkraft im Mittelpunkt der Schraube angreift, entsteht aber ein Drehmoment, dessen Größe der Exzentrität des Loches der Scheibe entspricht. Dieses Drehmoment bewirkt eine bei der Berechnung nicht berücksichtigte Veränderung der Richtung und Größe der Zugbeanspruchung und verursacht daher zusätzlich Gefahren. Überdies hat diese Anordnung den Nachteil, daß die Exzenterscheibe im Laufe der Zeit nicht mehr zurückdreht.It is also known to compensate for the length tolerance by means of eccentric disks, wherein a cylindrical disc is inserted into the correspondingly large hole in the cover plate, whose hole receiving the screw shaft is mounted eccentrically. By turning the disc the screw holes are brought to coincide. The eccentrically arranged hole in the disc is designed in such a way that it rotates with the screw that is inserted through it, so it is possible makes to tension the rod before the final tightening of the screw. Because the pulling force is the focus attacks the screw, but creates a torque, the size of the eccentricity of the hole in the disc is equivalent to. This torque causes a change in the which is not taken into account in the calculation Direction and magnitude of the tensile stress and therefore causes additional dangers. Moreover, this has Arrangement has the disadvantage that the eccentric disc no longer rotates back over time.
Die Erfindung bezweckt demgegenüber eine Anordnung, die einfacher ist und die vorgenannten Gefahrenquellen nicht besitzt. Die Erfindung beruht auf dem auch bei dem bekannten Spanndorn verwandten Prinzip, zwei Löcher dadurch in Übereinstimmung zu bringen, daß in beide Löcher ein Element eingetrieben wird, das bei diesem Eintreiben die Löcher zueinander zentriert.In contrast, the invention aims at an arrangement which is simpler and the aforementioned sources of danger does not own. The invention is based on the principle, which is also used in the known mandrel, to align two holes by driving an element in both holes that centers the holes with one another during this driving.
Das wesentliche Merkmal des geschraubten Stabanschlusses gemäß der Erfindung besteht darin, daß die Paßstücke 4, 5 als Kreisringe ausgebildet sind, deren äußere Ringfläche aus der eines Zylinders und eines symmetrischen Kegelstumpfes besteht, daß die Doppellaschen des Zugstabendes 1,2 mit zylindrischen Löchern größeren Durchmessers versehen sind, während das Knotenblech 3 ein doppelkegeliges Loch kleineren Durchmessers aufweist.The essential feature of the screwed rod connection according to the invention is that the fitting pieces 4, 5 are designed as circular rings, the outer ring surface of which consists of that of a cylinder and a symmetrical truncated cone that the double straps of the tension rod end 1,2 with cylindrical Larger diameter holes are provided, while the gusset plate 3 has a double-conical hole Has smaller diameter.
Die beiden kegelstumpfförmigen, mit ihrer gemeinsamen Achse senkrecht zur Stabachse stehenden, gegeneinanderweisend angeordneten ringförmigen Paßstücke wirken als Spannkörper, die durch axialeThe two frustoconical, with their common one Axis perpendicular to the rod axis, oppositely arranged annular Fitting pieces act as clamping bodies, which through axial
