Definitions

  • the present invention relates to a connecting device for assembly concrete elements, including tunnel segments.
  • the assemblies described in document EP 0 114 514 allow a setting faster placement of concrete tubular elements by pushing the TBM cylinders.
  • These assembly elements consist of a metal rod and two elements tubular provided opposite in the walls coming to be applied one against the other during of the assembly.
  • Said tubular elements consist of plastic tubes enclosing a clamping ring having a non-return crown protruding inside the tubular housing. During assembly, each half of the metal rod enters the tubular housing and its removal is prevented by the non-return crown.
  • This assembly is faster than that described above but requires manual intervention to maintain the spindle in the direction of assembly and its resistance to tensile forces it's not enough.
  • the present invention aims to solve the problems of the prior art.
  • the main objective of the invention is to ensure assembly that is both rapid and adaptable to the efforts and needs of the construction to be carried out.
  • the invention which consists of a process assembly of two elements, for example segments, each of the elements by example in concrete with a contact surface applied to a surface of the other element during assembly, the process of joining the contact surfaces by one or a plurality of pins, for example metallic pins, arranged perpendicular to said contact surfaces, characterized in that a first part of each spindle is first placed manually by screwing in the first element then in that the second part of the spindle is put in place and locked in the direction of return by a clamping force exerted on the elements to be assembled, in parallel to the direction of the spindle, said clamping force inducing a rotation of the spindle ending the screwing of the first part of the spindle in the first element.
  • the second part of the spindle is force-fitted or glued by an adhesive or by sealing with a mortar.
  • the spindle (7) has a quick pitch thread on its entire length, it is placed in the first element (A) by manual screwing in the plastic sleeve (2). In element (B) it is force fitted, by a clamping force parallel to the axis (3). In the application to segments, the clamping force is carried out by the tunnel boring machine.
  • the socket (1) of the previous example is replaced by a foot tube (9) anchor (8), the other elements being unchanged.
  • the pin (7) to quick thread is screwed into the element (A) and force-fitted into the sleeve (2) of the piece (B).
  • the part (A) has a turn anchor (11) sealed in the concrete during the molding of the part (A).
  • the spindle (7) is held in the part (A) by screwing into the coil (11) and force fitted into the sleeve (2) of the part (B).
  • FIGS. 4, 5, 6 comprise, on the one hand, parts anchor corresponding respectively to those of Figures 1,2,3 and include other share a metal pin, half of which has a quick thread and the other half a succession of frustoconical notches (12).
  • the notches (12) have frustoconical side walls, the largest diameters of which are directed towards the central part of the threaded rod to ensure the non-return function.
  • the spindle (7) is held in the part (A) by screwing and force-fitted in room (B).
  • the embodiment of Figure 7 includes a threaded rod (7) over its entire length and two anchor pieces in the pieces (A and B) which are anchor turns (11) quick thread.
  • the spindle is screwed into the element (A) then force-fitted into element (B).
  • the spindle (7) (see FIG. 8) has a part (7a) whose profile is adapted to that of the quick-turn turn ( Figures 8 and 9) arranged in the part (A) and a part (7b) with helical notching (15) anchored in the special socket (16) sealed in item (B) ..
  • the special socket (16) has a conical inlet (17) and a tubular body with external annular retaining notches (4) and an internal longitudinal hole (14).
  • a plurality of longitudinal grooves (13) are provided, for example three, for the evacuation of water or mud.
  • the spindle is manually screwed into the part (A) then force-fitted into the part (B) by a clamping force which, thanks to the shape and slope of the helical notch, also induces a rotation of the spindle ending the screwing of the first part (7a) of the spindle.

  1. Verfahren zur Verbindung von zwei Betonelementen, beispielsweise von Gewölbesteinen, wobei jedes der beispielsweise aus Beton bestehenden Elemente eine Kontaktfläche aufweist, die sich beim Zusammenfügen gegen eine Fläche des anderen Elementes anlegt, wobei gemäß dem Verfahren die Kontaktflächen durch eine oder mehrere, beispielsweise rechtwinklig zu den genannten Kontaktflächen angeordneten Spindeln aus beispielsweise Metall miteinander verbunden werden, dadurch gekennzeichnet, dass zunächst von Hand ein erster Bereich jeder Spindel durch Verschraubung am ersten Element angebracht wird und dass danach der zweite Bereich der Spindel angebracht und durch eine Klemmkraft, die auf die zu verbindenden Teile parallel zur Richtung der Spindel ausgeübt wird, gegen ein Zurückdrehen gesichert wird, wobei die genannte Klemmkraft zu einer Drehung der Spindel führt, durch die das Verschrauben des ersten Bereiches der Spindel in das erste Element abgeschlossen wird.
  2. Verfahren zur Verbindung gemäß Anspruch 1, dadurch gekennzeichnet, dass der zweite Bereich der Spindel unter Kraft eingepresst ist.
  3. Verfahren zur Verbindung gemäß Anspruch 1, dadurch gekennzeichnet, dass der zweite Bereich der Spindel im zweiten Element eingeklebt ist.
  4. Montagevorrichtung zur Verbindung und Verriegelung von Elementen (A) und (B), insbesondere Gewölbesteine aus Beton für die Verkleidung von Tunneln, wobei jedes der Elemente eine Kontaktfläche aufweist, die sich während der Montage gegen eine Kontaktfläche des angrenzenden Elementes anlegt, dadurch gekennzeichnet, dass sie zumindest die folgenden Merkmale aufweist:
    eine Spindel (7), von der jede Hälfte (7a, 7b) in Längsrichtung in das Innere eines zu verbindenden Elementes eindringt und über einen kleineren Bereich als seine Länge eine Vielzahl von Rückbewegungssicherungen aufweist und bei der der erste Bereich (7a) einen Gewindegang mit großer Steigung aufweist,
