Abstract
Description
Cette invention permet le transfert de charges entre deux zones de dallages en béton contiguës, coulées à des périodes différentes (joint de construction ou joint de coulage).This invention allows the transfer of loads between two contiguous concrete slab areas, cast at different times (construction joint or pouring joint).
L'invention permet le transfert de charges verticales, en autorisant toutefois les mouvements relatifs de chaque portion de dalle dans un plan horizontal et selon tous les axes (perpendiculaire et parallèle au joint).The invention allows the transfer of vertical loads, while allowing the relative movements of each slab portion in a horizontal plane and along all axes (perpendicular and parallel to the joint).
Les dallages en béton de grandes dimensions doivent être fractionnés pour permettre les mouvements liés au retrait et aux dilatations, mais aussi en fonction des quantités de dallage qu'il est possible d'exécuter dans une journée de travail. La surface maximale d'une zone dite de coulage est en général de l'ordre de 1 000 à 1 500 m2.Large concrete slabs should be split to accommodate movement related to shrinkage and expansion, as well as the amount of paving that can be done in a day's work. The maximum area of a so-called casting zone is generally of the order of 1000 to 1500 m 2 .
Entre deux zones de coulage, il est nécessaire de concevoir un joint de transition qui offre différentes caractéristiques :
- 1) le coffrage entre une zone de coulage A et une zone de coulage B ;
- 2) les zones A et B, du fait du retrait du béton dans le temps, vont s'éloigner d'une valeur qui peut atteindre 10 à 15 mm. L'angle constitué entre le joint de coulage et la surface du dallage doit être protégé, pour résister aux chocs liés à la circulation des engins de manutention sur le dallage. Sans protection, cet angle serait rapidement épaufré.
- 3) les charges verticales (roulantes par exemple) doivent être transmises de la zone A vers la zone B et inversement, pour éviter les problèmes dits de « pianotage » des portions de dalle respectives ;
- 4) le transfert de charges verticales ne doit pas s'opposer au libre mouvement dans un plan horizontal de chaque portion de dalle.
- 1) the formwork between a casting zone A and a casting zone B;
- 2) Zones A and B, due to the removal of concrete over time, will move away from a value that can reach 10 to 15 mm. The angle formed between the casting joint and the pavement surface must be protected, to withstand shocks related to the movement of the handling equipment on the pavement. Without protection, this angle would be quickly blotched.
- 3) the vertical loads (rolling for example) must be transmitted from the zone A to the zone B and vice versa, to avoid the problems known as "strumming" of the respective portions of slab;
- 4) the transfer of vertical loads must not oppose the free movement in a horizontal plane of each slab portion.
Il s'agit d'un coffrage comportant une forme en V destiné au clavetage vertical des portions A et B (
Cette technique permet :
- 1° le coffrage entre A et B (tôle 2.1) ;
- 2° le renfort des angles de joints à l'aide des deux cornières (2.2) mais il faut noter que très souvent, le béton n'ira pas combler le vide situé sous la cornière (zones 2.5 et 2.6) créant ici un défaut de solidité à l'origine de nombreux sinistres ;
- 3° le transfert des charges verticales à l'aide des goujons (barre en acier 2.3) ;
- 4° le libre mouvement des zones A et B dans le plan horizontal grâce au fourreau (2.4). Cependant, ce mouvement ne peut se faire que selon un axe perpendiculaire au joint -alors que le libre mouvement dans le plan horizontal doit être permis dans tous les axes, pour permettre le libre retrait du béton, en particulier dans les angles des différentes zones de coulage.
- 1 ° the formwork between A and B (sheet 2.1);
- 2 ° the reinforcement of the joint angles using the two angles (2.2) but it should be noted that very often, the concrete will not fill the void located under the angle (zones 2.5 and 2.6) creating here a defect of solidity at the origin of many claims;
- (3) the transfer of vertical loads by means of the studs (steel bar 2.3);
- 4 ° the free movement of zones A and B in the horizontal plane thanks to the sheath (2.4). However, this movement can be done only along an axis perpendicular to the joint -alors that the free movement in the horizontal plane must be allowed in all the axes, to allow the free withdrawal of the concrete, in particular in the angles of the different zones of casting.
Cette technique permet:
- 1° le coffrage entre A et B (tôle 3.1) ;
- 2° le renfort des angles de joints, à l'aide de deux fers plats (3.2). Il faut cependant noter que ces plats n'offrent qu'une faible inertie dans le plan horizontal. La mise en oeuvre est donc difficile, le système devant être maintenu de façon importante pendant le coulage. Souvent, ce type de joint, du fait de la poussée du béton, bouge et le joint « serpente » ;
- 3° le transfert des charges verticales et le libre mouvement dans le plan horizontal selon tous les axes, grâce au système DIAMOND DOWEL (3.3).
- 1 ° the formwork between A and B (sheet 3.1);
- 2 ° reinforcement of the joint angles, using two flat irons (3.2). It should be noted, however, that these dishes offer only low inertia in the horizontal plane. The implementation is difficult, the system to be maintained significantly during casting. Often, this type of joint, because of the thrust of the concrete, moves and the seal "snakes";
- (3) the transfer of vertical loads and the free movement in the horizontal plane along all axes, thanks to the DIAMOND DOWEL system (3.3).
- 1° le coffrage est assuré par les deux tôles (4.1) et 4.2) ;1 ° the formwork is provided by the two sheets (4.1) and 4.2);
- 2° les angles du joint sont protégés par le sommet des tôles (4.2) et 4.1) ;(2) the corners of the joint are protected by the top of the plates (4.2) and 4.1);
- 3° les charges verticales sont transmises par la clé continue (fer plat 4.3), mais le fait que cette forme parallèle au plan du dallage (fer plat 4.3) soit continue constitue une faiblesse du dallage, un risque de mauvaise répartition du béton, sous cette forme (zones 4.4 et 4.5) et une rupture selon les lignes (4.6) et 4.7).3 ° the vertical loads are transmitted by the continuous key (flat iron 4.3), but the fact that this shape parallel to the plane of the pavement (flat iron 4.3) is continuous constitutes a weakness of the pavement, a risk of bad distribution of the concrete, under this form (zones 4.4 and 4.5) and a break according to lines (4.6) and 4.7).
Le libre mouvement dans le plan horizontal est assuré dans tous les axes, sous réserve d'une horizontalité parfaite du fer plat (4.3), ce qui sous-entend une pose parfaite de l'ensemble du joint.The free movement in the horizontal plane is ensured in all axes, subject to a perfect horizontality of the flat iron (4.3), which implies a perfect installation of the entire joint.
L'invention permet d'assurer la transition entre deux zones de dallage en béton contiguës, exécutées à des périodes différentes tout en évitant, par rapport au joint « PERMABAN », que le joint ainsi obtenu ne serpente. L'invention propose un système tel que défini par la revendication 1. Des modes de réalisation avantageux du système selon l'invention sont définis dans les revendications dépendantes 2 à 10.The invention makes it possible to ensure the transition between two contiguous concrete pavement zones, executed at different periods while avoiding, with respect to the "PERMABAN" joint, that the joint thus obtained does not wind. The invention proposes a system as defined by claim 1. Advantageous embodiments of the system according to the invention are defined in the dependent claims 2 to 10.

L'invention permet :
- 1° le coffrage des rives du dallage, lors du coulage de la 1ère partie, à l'aide de la tôle (5.1).
- 1 formwork shores of paving, during casting of the part 1, with the plate (5.1).
Cette tôle comporte un pli à la base, lui donnant de la rigidité.This sheet has a fold at the base, giving it rigidity.
La hauteur h de cette tôle sera l'épaisseur nominale du dallage diminuée de 1 cm pour absorber la tolérance de planimétrie de la forme support du dallage (± 1 cm).The height h of this sheet shall be the nominal thickness of the pavement minus 1 cm to absorb the planimetric tolerance of the slab support form (± 1 cm).
Un vérin de réglage (5.2), constitué d'une simple vis, permet un réglage parfait en altitude du joint, à chaque jonction de tronçon de joint
- 2° le renfort des angles situés entre la surface du dallage et le plan du joint à l'aide de deux fers plats disposés verticalement (la répartition du béton au long de ces profils est parfaite). La liaison entre ces fers plats avec chaque corps de dallage (A et B) se fait à l'aide d'une poutre de type treillis bidirectionnel (5.8) qui permet à la fois la liaison fer plat dallage, mais aussi d'assurer la rigidité des fers plats, lors de la pose et du coulage, évitant que le joint ne « serpente » dans le dallage. Cette liaison est complétée par une patte à scellement intermédiaire (5.5).
- 2 ° reinforcement of the angles between the surface of the pavement and the plane of the joint using two flat irons arranged vertically (the distribution of the concrete along these profiles is perfect). The connection between these flat bars with each paving body (A and B) is made using a bidirectional trellis-type beam (5.8) which allows both the flat iron connection slab, but also to ensure the rigidity of flat irons, during laying and casting, avoiding that the seal "snakes" in the pavement. This connection is completed by an intermediate sealing lug (5.5).
La liaison provisoire entre les fers plats (5.3) et (5.4) est assurée avec des boulons en « Nylon » '5.6), destinés à se rompre lors du retrait du béton.
- 3° le transfert des charges verticales (anti-pianotage) est assuré par des platines de clavetage (5.7) dont le fonctionnement est le suivant (
fig. 6 ) :

- une platine de clavetage (6.3), en acier de section rectangulaire est glissée dans le fourreau (6.1), cette platine se prolonge dans la zone de coulage B ;
- la cote h de cette platine (6.3) permet un glissement sans jeu par rapport à la cote H intérieure du fourreau (6.1) ;
- la cote 1 de cette platine 6.3 est largement inférieure (15 à 20 mm) à la cote L intérieure du fourreau (6.1).
- la platine (6.3) est maintenue en position dans le fourreau (6.1) à l'aide de deux boulons (6.4) en « Nylon » de faible section destinés à se rompre lors du retrait du béton ;
- les orifices (6.5) grisés sur la figure seront obturés par du ruban adhésif de façon à éviter la pénétration du béton dans la réservation située entre les parois latérales de la platine (6.3) et celles du fourreau (6.1) ;
- la partie de la platine (6.3) située dans la zone B du dallage sera solidaire de la portion de dallage B ;
- la partie de la platine (6.3) située dans la zone A du dallage sera libre (après rupture de boulons (6.4) dans un plan horizontal (x et y) à l'intérieur du fourreau (601) (jeu latéral), mais clavetée dans un plan vertical 'z) (pas de jeu au-dessus et au-dessous de la platine (6.3).
- 3 ° the transfer of the vertical loads (anti-strumming) is ensured by keying plates (5.7) whose operation is as follows (
Fig. 6 ):
- a metal sleeve (6.1) of rectangular section is welded to the shuttering sheet (6.2), perpendicular to this sheet, in the casting zone A;
- a locking plate (6.3), of rectangular section steel is slid into the sleeve (6.1), this plate is extended in the casting zone B;
- the dimension h of this plate (6.3) allows a slip without play with respect to the inner dimension H of the sleeve (6.1);
- the dimension 1 of this plate 6.3 is much lower (15 to 20 mm) to the inner dimension L of the sleeve (6.1).
- the plate (6.3) is held in position in the sheath (6.1) by means of two bolts (6.4) in "nylon" of small section intended to break during removal of the concrete;
- the orifices (6.5) greyed in the figure will be closed by tape so as to prevent the penetration of concrete in the reservation located between the side walls of the plate (6.3) and those of the sleeve (6.1);
- the part of the plate (6.3) located in the zone B of the pavement will be integral with the paving portion B;
- the part of the plate (6.3) situated in zone A of the pavement will be free (after breaking bolts (6.4) in a horizontal plane (x and y) inside the sheath (601) (side play), but keyed in a vertical plane 'z) (no play above and below the stage (6.3).
Cette disposition permet le transfert des charges selon l'axe z, mais le libre retrait du béton selon les axes x et y.This arrangement allows the transfer of loads along the z axis, but the free withdrawal of the concrete along the x and y axes.
