Definitions

  • the present invention relates to a connecting device for assembling concrete elements, in particular tunnel segments.
  • the assemblies described in document EP 0 114 514 allow a faster installation of the tubular concrete elements by pushing the jacks of the tunnel boring machine.
  • These assembly elements consist of a metal rod and two tubular elements provided facing each other in the walls which come to bear against one another during assembly.
  • Said tubular elements consist of plastic tubes enclosing a clamping ring having a non-return crown projecting 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 is not sufficient.
  • the present invention aims to solve the problems of the prior art.
  • the main objective of the invention is to ensure an assembly that is both rapid and adaptable to the efforts and needs of the construction to be carried out.
  • the invention consists of a method of assembling two elements, for example segments, each of the elements for example of concrete having a contact surface which comes to be applied on a surface of the other element.
  • process consisting in 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 pin is first put in place manually by screwing in the first element then in that the second part of the spindle is put in place and blocked in the return direction by a clamping force exerted on the elements to be assembled, parallel to the direction of the spindle.
  • the second part of the spindle is force-fitted or glued with glue or by sealing with a mortar.
  • the spindle (7) has a quick pitch thread over its entire length, it is put into place in the first element (A) by manual screwing into the plastic bushing (2). In the element (B) it is force fitted, by a clamping force parallel to the axis (3). In the application to the segments, the clamping effort is carried out by the TBM.
  • FIG. 2 We now describe a second embodiment of the invention shown in FIG. 2.
  • the sleeve (1) of the previous example is replaced by a tube (9) with anchoring base (8), the other elements being unchanged.
  • the spindle (7) with a quick thread is screwed into the element (A) and force-fitted into the sleeve (2) of the part (B).
  • the part (A) comprises an anchoring turn (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 turn (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 also have a metal pin, one half of which has a fast 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 into the part (B).
  • FIG. 7 comprises a threaded rod (7) over its entire length and two anchoring pieces in the pieces (A and B) which are anchoring turns (11) with fast thread.
  • the spindle is screwed into the element (A) and then force-fitted into the element (B).
  • the spindle (7) (see FIG. 8) has a part (7a) whose profile is adapted to that of the rapid-pitch turn (FIGS. 8 and 9) placed in the part (A) and a part (7b) with notching helical (15) anchoring in the special sleeve (16) sealed in the element (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), for example three, are provided 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 the slope of the helical notching, also induces a rotation of the spindle ending the screwing of the first part (7a) of the spindle.
