Abstract

The procedure consists of using one or more metal pins in two sections (1, 2) which are fitted into the end faces of the components perpendicular to their surfaces. The two sections of each pin are screwed manually into holes made for them in the concrete components, and they are then joined together by a rod (7) which it fitted by force into each of the pin sections and if necessary fixed in place with an adhesive. The two ends (7a, 7b) of the rod are made with anti-return elements in the form of threads, truncated conical teeth or anchoring spirals. The first sections (1, 2) of the metal pins can be in the shape of tubular dowels with conical inlet ends.

Description

La présente invention concerne un dispositif de liaison pour assemblage d'éléments en béton, notamment des voussoirs de tunnel.The present invention relates to a connecting device for assembling concrete elements, in particular tunnel segments.

On connaît déjà des dispositifs pour assembler entre-eux des voussoirs ou des éléments en béton pour le chemisage des parois d'un tunnel.Devices are already known for assembling between them segments or concrete elements for lining the walls of a tunnel.

Par exemple, dans le document FR 2 669 061, on réalise la liaison en torsadant ensemble les extrémités dépassantes des armatures de deux éléments en béton voisins. Le principal inconvénient de cette méthode est d'être peu rapide.Cette méthode est peu rapide et nécessite un clavetage béton.For example, in document FR 2 669 061, the connection is made by twisting together the protruding ends of the reinforcements of two neighboring concrete elements. The main disadvantage of this method is that it is not very fast. This method is not very fast and requires concrete keying.

Les assemblages décrits dans le document EP 0 114 514 permettent une mise en place plus rapide des éléments tubulaires en béton par poussée des vérins du tunnelier. Ces éléments d'assemblage sont constitués d'une tige métallique et de deux éléments tubulaires prévus en vis-à-vis dans les parois venant s'appliquer l'une contre l'autre lors de l'assemblage. Lesdits éléments tubulaires sont constitués de tubes plastiques enserrant une bague de serrage présentant une couronne anti-retour dépassant à l'intérieur du logement tubulaire. Lors de l'assemblage, chaque moitié de la tige métallique entre dans le logement tubulaire et son retrait est empêché par la couronne anti-retour. Cet assemblage est plus rapide que celui décrit ci-dessus mais nécessite une intervention manuelle pour maintenir la broche dans la direction d'assemblage et sa résistance aux efforts de traction n'est pas suffisante.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.

La présente invention vise à résoudre les problèmes de l'art antérieur.The present invention aims to solve the problems of the prior art.

L'objectif principal de l'invention est d'assurer un assemblage à la fois rapide et adaptable aux efforts et besoins de la construction à réaliser.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.

Ces objectifs sont atteints grâce à l'invention qui consiste en un procédé d'assemblage de deux éléments, par exemple des voussoirs, chacun des éléments par exemple en béton présentant une surface de contact venant s'appliquer sur une surface de l'autre élément lors de l'assemblage, procédé consistant à réunir les surfaces de contact par une ou une pluralité de broches par exemple métalliques disposées perpendiculairement auxdites surfaces de contact, caractérisé en ce qu'une première partie de chaque broche est d'abord mise en place manuellement par vissage dans le premier élément puis en ce que la deuxième partie de la broche est mise en place et bloquée dans le sens du retour par un effort de serrage exercé sur les éléments à assembler, parallèlement à la direction de la broche.These objectives are achieved thanks to the invention which 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. during assembly, 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.

Selon le cas, la deuxième partie de la broche est emmanchée en force ou collée par une colle ou par un scellement avec un mortier.Depending on the case, the second part of the spindle is force-fitted or glued with glue or by sealing with a mortar.

L'invention consiste également en un dispositif d'assemblage pour la liaison et le blocage d'éléments (A) et (B) notamment des voussoirs en béton pour le chemisage de tunnels, chacun des éléments comportant une surface de contact venant s'appliquer lors de l'assemblage contre une surface de contact de l'élément voisin, caractérisé en ce qu'il est constitué au moins de :

  • une pièce d'ancrage (1,2) scellée dans un des éléments (A,B),
  • une broche par exemple métallique (7) dont chaque moitié (7a,7b) pénètre longitudinalement à l'intérieur d'un élément à assembler, et comporte sur une partie au moins de sa longueur une pluralité de moyens anti-retour.
The invention also consists of an assembly device for the connection and blocking of elements (A) and (B) in particular concrete segments for lining tunnels, each of the elements comprising a contact surface applied during assembly against a contact surface of the neighboring element, characterized in that it consists of at least:
  • an anchor (1,2) sealed in one of the elements (A, B),
  • a spindle, for example a metal spindle (7), each half of which (7a, 7b) penetrates longitudinally inside an element to be assembled, and comprises, over at least part of its length, a plurality of non-return means.

On décrit d'abord un premier exemple de réalisation visible sur la figure 1.We first describe a first embodiment visible in Figure 1.

L'invention est constituée de :

  • deux pièces d'ancrage (1,2) scellées chacune dans un élément en béton (A,B) et disposées en vis-à-vis. Lesdites pièces (1 et 2) sont mises en place lors de la fabrication des éléments en béton et sont en forme de douille plastique tubulaire dont l'axe longitudinal (3) est perpendiculaire à la surface à assembler, leur paroi extérieure est équipée de crans annulaires (4) augmentant l'ancrage des douilles dans les éléments en béton (A,B). Les ouvertures coniques (5,6) des trous d'assemblage dans lesquelles sont placées les douilles (1,2) facilitent l'entrée de la broche décrite ci-après.
  • une broche métallique (7), dont chaque moitié (7a,7b) coopère respectivement avec une pièce d'ancrage (1 ou 2), assure la liaison des éléments en béton (A,B) et assure la reprise des efforts de traction et de cisaillement.
The invention consists of:
  • two anchor pieces (1,2) each sealed in a concrete element (A, B) and arranged opposite. Said parts (1 and 2) are put in place during the production of the concrete elements and are in the form of a tubular plastic sleeve whose longitudinal axis (3) is perpendicular to the surface to be assembled, their outer wall is equipped with notches annulars (4) increasing the anchoring of the sockets in the concrete elements (A, B). The conical openings (5,6) of the assembly holes in which the sockets (1,2) are placed facilitate the entry of the spindle described below.
  • a metal spindle (7), each half of which (7a, 7b) cooperates respectively with an anchoring piece (1 or 2), ensures the connection of the concrete elements (A, B) and ensures the resumption of the tensile forces and shear.

Dans l'exemple de la figure 1, la broche (7) comporte un filet à pas rapide sur toute sa longueur, elle est mise en place dans le premier élément (A) par vissage manuel dans la douille plastique (2). Dans l'élément (B) elle est emmanchée en force, par un effort de serrage parallèle à l'axe (3). Dans l'application aux voussoirs, l'effort de serrage est réalisé par le tunnelier.In the example of Figure 1, 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.

On décrit à présent un deuxième exemple de réalisation de l'invention représenté en figure 2.We now describe a second embodiment of the invention shown in FIG. 2.

La douille (1) de l'exemple précédent est remplacée par un tube (9) à pied d'ancrage (8), les autres éléments étant inchangés. Comme précédemment la broche (7) à filet rapide est vissée dans l'élément (A) et emmanchée en force dans la douille (2) de la pièce (B).The sleeve (1) of the previous example is replaced by a tube (9) with anchoring base (8), the other elements being unchanged. As before, the spindle (7) with a quick thread is screwed into the element (A) and force-fitted into the sleeve (2) of the part (B).

Dans le troisième exemple de la figure 3, la pièce (A) comporte une spire d'ancrage (11) scellée dans le béton lors du moulage de la pièce (A).In the third example of FIG. 3, the part (A) comprises an anchoring turn (11) sealed in the concrete during the molding of the part (A).

La broche (7) est maintenue dans la pièce (A) par vissage dans la spire (11) et emmanchée en force dans la douille (2) de la pièce (B).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).

Les exemples de réalisation des figures 4, 5, 6 comportent d'une part des pièces d'ancrage correspondant respectivement à celles des figures 1, 2, 3 et comportent d'autre part une broche métallique dont une moitié présente un filet rapide et l'autre moitié une succession de crans tronconiques (12).The exemplary embodiments of 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).

Les crans (12) ont des parois latérales tronconiques dont les plus grands diamètres sont dirigés vers la partie centrale de la tige filetée pour assurer la fonction d'anti-retour.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.

La broche (7) est maintenue dans la pièce (A) par vissage et emmanchée en force dans la pièce (B).The spindle (7) is held in the part (A) by screwing and force-fitted into the part (B).

L'exemple de réalisation de la figure 7 comporte une tige filetée (7) sur toute sa longueur et deux pièces d'ancrage dans les pièces (A et B) qui sont des spires d'ancrage (11) à filet rapide.The exemplary embodiment of 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.

Dans cet exemple de réalisation, la broche est vissée dans l'élément (A) puis emmanchée en force dans l'élément (B).In this exemplary embodiment, the spindle is screwed into the element (A) and then force-fitted into the element (B).

Les figures 9 à 11 montrent en détail un mode de réalisation préféré qui présente les avantages suivants :

  • la broche ne peut être inversée lors de la pose ce qui évite les erreurs de pose,
  • une des pièces d'ancrage comporte des dispositifs d'évacuation de l'eau ou de la boue qui aurait pu être comprimée dans la douille par la broche en mouvement, ce qui permet l'utilisation de l'invention dans l'eau ou dans la boue.
Figures 9 to 11 show in detail a preferred embodiment which has the following advantages:
  • the spindle cannot be reversed during installation which avoids installation errors,
  • one of the anchoring parts includes devices for discharging water or mud which could have been compressed in the socket by the moving spindle, which allows the invention to be used in water or in mud.

La broche (7) (voir figure 8) comporte une partie (7a) dont le profil est adapté à celui de la spire à pas rapide (figures 8 et 9) disposée dans la pièce (A) et une partie (7b) à crantage hélicoïdal (15) venant s'ancrer dans la douille spéciale (16) scellée dans l'élément (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).

La douille spéciale (16) a une entrée conique (17) et un corps tubulaire avec des crans annulaires externes de retenue (4) et un trou longitudinal interne (14).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).

En outre, on prévoit une pluralité de gorges (13) longitudinales, par exemple trois, pour l'évacuation de l'eau ou de la boue.In addition, a plurality of longitudinal grooves (13), for example three, are provided for the evacuation of water or mud.

Dans cet exemple de réalisation, la broche est vissée manuellement dans la pièce (A) puis emmanchée en force dans la pièce (B) par un effort de serrage qui, grâce à la forme et à la pente du crantage hélicoïdal, induit également une rotation de la broche terminant le vissage de la première partie (7a) de la broche.In this exemplary embodiment, 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.

  • * ancrage rapide par effort de serrage exercé sur les éléments en béton parallèlement à la broche de liaison,
  • * mise en place rapide et sans aucun outil de la première partie de la broche dans le premier élément (A) par vissage manuel, la deuxième partie de la broche étant alors automatiquement centrée et présentée convenablement à l'entrée de la réservation ou de la douille d'ancrage du deuxième élément (B).
  • * adaptabilité du dispositif de liaison à la reprise des efforts de traction et de cisaillement propres au chantier. Cette adaptabilité est réalisée selon le cas en fonction :
