  • the manufacturing tolerances of the connecting pieces and of the rule are such that locking the beads of the lower ends of the legs of the rule in the hollows of the connecting pieces is not always simple.

Description

La présente invention concerne un dispositif de formation de joints d'un dallage de type industriel, généralement en béton, selon la première partie de la revendication 1.The present invention relates to a device for forming joints of an industrial type paving, generally made of concrete, according to the first part of claim 1.

Il existe déjà un dispositif qui permet de réaliser à la fois les opérations suivantes:

  • 1 ) coffrage,
  • 2) support de règle vibrante,
  • 3) joint de dilatation dit sec, mais solidaire tout de même du béton qui effectue son retrait,
  • 4) joint de dilatation à mastiquer.
There is already a device which makes it possible to carry out both of the following operations:
  • 1) formwork,
  • 2) vibrating rule support,
  • 3) so-called dry expansion joint, but still integral with the concrete which performs its removal,
  • 4) chewing expansion joint.

Ce dispositif est décrit et revendiqué dans la demande de brevet français déposée le 5 décember 1980 par le présent demandeur sous le N° 80 25822 (EP-A-0 053 977).This device is described and claimed in the French patent application filed on December 5, 1980 by the present applicant under No. 80 25822 (EP-A-0 053 977).

La première pièce ou règle dudit dispositif est une barre ayant un profil en forme de pince à linge. La règle se présente sous deux formes selon que l'on veut réaliser un joint à mastiquer ou un joint dit sec. Pour la réalisation des joints à mastiquer, la règle utilisée a un profil formé de deux jambes réunies par un sommet. Le flanc extérieur des jambes est droit et la largeur de la règle va en diminuant de son sommet à sa base, si bien qu'on peut la retirer lorsque le dallage est terminé. Pour réaliser les joints dits sec on utilise une règle légèrement différente. Son profil est toujours formé de deux jambes réunies par leur sommet, mais les flancs externes desdites jambes comportent des oreilles en queue d'aronde et leurs extrémités inférieures ont la forme d'un bourrelet.The first part or rule of said device is a bar having a profile in the shape of a clothespin. The rule comes in two forms depending on whether you want to make a putty joint or a so-called dry joint. For the realization of joints to be putty, the rule used has a profile formed by two legs joined by a vertex. The outer flank of the legs is straight and the width of the rule decreases from its top to its base, so that it can be removed when the paving is finished. To make the so-called dry joints, a slightly different rule is used. Its profile is always formed by two legs joined by their top, but the external sides of said legs have ears in dovetail and their lower ends have the shape of a bead.

Les pièces d'assemblage et de support ont un profil qui comporte deux jambes obliques dont les extrémités supérieures sont réunies par un sommet surmonté en son milieu par une crête à flancs verticaux. Ledit sommet comporte de chaque côté de la crête un creux dont l'ouverture est légèrement resserrée. Les jambes obliques sont reliées par une crête horizontale qui les empêche de s'écarter.The assembly and support parts have a profile which has two oblique legs, the upper ends of which are joined by a vertex surmounted in the middle by a ridge with vertical sides. Said vertex comprises on each side of the ridge a hollow, the opening of which is slightly narrowed. The oblique legs are connected by a horizontal ridge which prevents them from spreading.

Enfin, on dispose de guides de croisement qui ont la forme de dièdres dont l'arête est destinée à être disposée verticalement. Ils ont la même hauteur que les pièces d'assemblage et de support.Finally, there are crossing guides which have the form of dihedrons whose edge is intended to be arranged vertically. They have the same height as the assembly and support parts.

Avec ces pièces, on réalise un maillage sur la surface à daller. On coupe des parties de règle aux dimensions voulues. On dispose sous les parties de règle des éléments de support et d'assemblage, les jambes de la règle chevauchant la crête des pièces d'assemblage, les bourrelets des extrémités inférieures des jambes se verrouillant par pression dans les creux disposés sur le sommet des pièces d'assemblage. A titre indicatif, pour des mailles de 3 à 4 m de côté, la distance entre deux pièces d'assemblage voisines peut être de l'ordre de 50 cm. On place alors les parties de règle avec les pièces d'assemblage sur la surface à daller en disposant les guides de croisement de façon que les extrémités des parties de règle chevauchent les ailettes desdits guides de croisement. On coule ensuite un premier béton pour ancrer les pièces d'assemblage. Cette opération se fait en général la veille du coulage du dallage.With these parts, a mesh is made on the surface to be tiled. Ruler parts are cut to the desired dimensions. Support and assembly elements are placed under the ruler parts, the ruler legs overlapping the crest of the assembly parts, the beads of the lower ends of the legs locking by pressure in the recesses arranged on the top of the parts assembly. As an indication, for meshes of 3 to 4 m on a side, the distance between two neighboring joining pieces can be of the order of 50 cm. The rule parts are then placed with the assembly pieces on the surface to be paved by arranging the crossing guides so that the ends of the rule parts overlap the fins of said crossing guides. Then pour a first concrete to anchor the assembly parts. This operation is generally carried out the day before the paving is poured.

A l'usage, on s'est rendu compte que ces diverses pièces permettaient d'obtenir les résultats escomptés, mais qu'elles pouvaient encore être perfectionnées. Ainsi, la règle doit resister à des efforts importants, par exemple quand elle supporte la règle vibrante, sans se cintrer, ni se vriller entre les pièces d'assemblage. Pour résoudre ce problème, on peut diminuer l'espacement des pièces d'assemblage, mais on réduit alors les zones dans lesquelles le béton peut couler sous la règle entre deux pièces d'assemblage et on réduit le clavetage entre les divers panneau du dallage.In use, we realized that these various parts made it possible to obtain the expected results, but that they could still be improved. Thus, the rule must withstand significant forces, for example when it supports the vibrating rule, without bending or twisting between the assembly parts. To solve this problem, the spacing of the joining pieces can be reduced, but the areas in which the concrete can flow under the rule between two joining pieces are reduced and the keying between the various panels of the paving is reduced.

Par ailleurs, les tolérances de fabrication des pièces d'assemblage et de la règle sont telles que le verrouillage des bourrelets des extrémités inférieures des jambes de la règle dans les creux des pièces d'assemblage n'est pas toujours simple. Si le bourrelet, en bas d'une jambe, est un peu trop large, ou bien l'ouverture d'un creux un peu trop petite, il devient très difficile, voire impossible, d'engager le bourrelet dans le creux dont le bord externe est trop court pour être élastique. Sie les bourrelet des jambes ne sont pas suffisamment larges, ou bien les ouvertures des creux un peu trop larges, la ou les pièces d'assemblage s'accrochent mal sous la règle au moment de l'assemblage, avant la coulée de la couche de béton dans laquelle se noient les bases des pièces d'assemblage.Furthermore, the manufacturing tolerances of the connecting pieces and of the rule are such that locking the beads of the lower ends of the legs of the rule in the hollows of the connecting pieces is not always simple. If the bead, at the bottom of one leg, is a little too wide, or the opening of a hollow a little too small, it becomes very difficult, if not impossible, to engage the bead in the hollow whose edge external is too short to be elastic. If the beads of the legs are not wide enough, or the openings of the hollows a little too wide, the assembly piece (s) hang badly under the ruler at the time of assembly, before pouring the layer of concrete in which the bases of assembly parts drown.

Un objet de la présente invention consiste donc à prévoir une règle suffisamment rigide pour supporter les efforts auxquels elle est exposée sans se déformer et sans nécessiter la multiplication des pièces d'assemblage.An object of the present invention therefore consists in providing a rule which is sufficiently rigid to withstand the forces to which it is exposed without deforming and without requiring the multiplication of assembly parts.

Un autre objet de la présente invention consiste à prévoir un moyen de fixation de la règle sur les pièces d'assemblage qui soit pratique et efficace.Another object of the present invention is to provide a means of fixing the rule on the assembly parts which is practical and effective.

Un autre objet de la présente invention consiste à prévoir des pièces d'assemblage qui puissent également servir pour les points de croisement.Another object of the present invention is to provide assembly parts which can also be used for crossing points.

Les objets de l'invention mentionnés ci-dessus, ainsi que d'autres, sont atteints par la mise en oeuvre de combinaisons de moyens définies dans la revendication 1. Des mesures préférentielles sont indiquées dans les revendications dépendantes.The objects of the invention mentioned above, as well as others, are achieved by the use of combinations of means defined in claim 1. Preferential measures are indicated in the dependent claims.

Les caractéristiques de l'invention mentionnées ci-dessus, ainsi que d'autres, apparaîtront plus clairement à la lecture de la description d'exemples de réalisation, la description étant faite en relation avec les dessins joints, parmi lesquels:

  • La fig. 1 est une vue en perspective de la première pièce,

  • la fig. 5 est une vue en coupe d'une variante de la pièce de la fig. 3, qui est adaptée à la première pièce de la fig. 4.
The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the description of exemplary embodiments, the description being made in relation to the accompanying drawings, among which:
  • Fig. 1 is a perspective view of the first part,
  • fig. 2 is a perspective view of an assembly part,
  • fig. 3 is a perspective view of an assembly piece whose feet are replaced by a horizontal plate,
  • fig. 4 is a sectional view of a variant of the first part, and
  • fig. 5 is a sectional view of a variant of the part of FIG. 3, which is adapted to the first part of FIG. 4.

La première pièce ou règle, représentée à la fig. 1, est une crête 50 dont la partie inférieure du profil a la forme d'un cavalier composé de deux jambes rapprochées 51 et 52 rejointes à leurs extrémités supérieures par un sommet 53. Les flancs intérieurs des jambes 51 et 52 comportent des bossages 54 et 55 à une certaine distance au-dessous du sommet 53. On verra dans la suite l'utilité des bossages linéaires 54 et 55.The first piece or ruler, shown in fig. 1, is a ridge 50 whose lower part of the pro wire in the form of a jumper composed of two close legs 51 and 52 joined at their upper ends by a vertex 53. The inner flanks of the legs 51 and 52 have bosses 54 and 55 at a certain distance below the vertex 53 We will see in the following the usefulness of the linear bosses 54 and 55.

Le cavalier est surmonté d'une poutre creuse dont la paroi inférieure est constituée par le sommet 53. La poutre creuse comporte encore un voile horizontal 56 dans sa partie médiane et une paroi supérieure horizontale 57 qui est sensiblement plus épaisse que le sommet 53 et le voile 56. Les flancs externes de la poutre creuxe et les flancs externes des jambes 51 et 52 du cavalier comportent des oreilles en queue d'aronde 58.The rider is surmounted by a hollow beam whose lower wall is formed by the top 53. The hollow beam also has a horizontal veil 56 in its middle part and a horizontal upper wall 57 which is substantially thicker than the top 53 and the sail 56. The external sides of the hollow beam and the external sides of the legs 51 and 52 of the rider have dovetail ears 58.

Les oreilles en queue d'aronde 58 constituant des nervures, le sommet 53, la paroi supérieure 57 et le voile 56 tendent à augmenter le module d'inertie de la poutre et de l'ensemble de la règle, c'est-à-dire la rigidité de celle-ci. A titre d'exemple, les dimensions approximatives de la règle 50 peuvent être les suivantes: hauteur totale, 5 cm; épaisseur des jambes, 2 mm; épaisseur de la paroi supérieure, 3 à 4 mm, hauteur des oreilles 58, 5 mm; épaisseur du sommet 53 et du voile 56: 1,5 mm. Un règle ayant les dimensions mentionnées ci-dessus permet d'utiliser des support espacés de 50 cm ou plus. Afin de positionner facilement les pièces d'assemblage sous la règle 50, les flancs externes de ladite règle 50 comportent des repères, par exemple tous les 50 cm.The dovetailed ears 58 constituting ribs, the top 53, the upper wall 57 and the wall 56 tend to increase the inertia module of the beam and of the whole rule, that is to say say the rigidity of it. By way of example, the approximate dimensions of the rule 50 may be as follows: total height, 5 cm; thickness of the legs, 2 mm; thickness of the upper wall, 3 to 4 mm, height of the ears 58, 5 mm; thickness of the top 53 and of the veil 56: 1.5 mm. A ruler with the dimensions mentioned above allows the use of supports spaced 50 cm or more. In order to easily position the assembly pieces under the rule 50, the outer sides of said rule 50 have marks, for example every 50 cm.

La pièce d'assemblage 59 représentée à la fig. 2 comporte un pied dont le profil a la forme d'un V inversé. Les pieds des jambes 60 et 61 comportent respectivement des pointes 62 et 63 et des talons 64 et 65 qui s'arc-boutent contre les jambes. Le sommet 66 du V inversé est surmonté d'une crête 67 dont la hauteur est sensiblement égale à la hauteur intérieure du cavalier de la règle 50.The assembly part 59 shown in FIG. 2 comprises a foot whose profile has the shape of an inverted V. The feet of the legs 60 and 61 respectively have points 62 and 63 and heels 64 and 65 which are braced against the legs. The vertex 66 of the inverted V is surmounted by a crest 67 whose height is substantially equal to the interior height of the rider of the rule 50.

Le sommet 66 comporte deux creux 68 et 69 respectivement de chaque côté de la base de la crête 67. La crête 67 a une section telle que le cavalier de la règle 50 la chevauche en la serrant entre les bossages 54 et 55. Le haut de la crête 67 a la forme d'un bourrelet 70 qui se verrouille entre les bossages 54 et 55, le sommet 53 et les flancs intérieurs du cavalier de la règle 50 quand on place celle-ci sur la pièce 59. A titre indicatif, l'épaisseur de la crête 67 peut être de 3,65 mm dans sa partie inférieure et médiane, et de 3,85 mm à la hauteur du bourrelet 70, qui a donc une surépaisseur de 0,1 mm de chaque côté. Cette surépaisseur est égale à celle des bossages 54 et 55 à l'intérieur des jambes 51 et 52 de la règle. Une fois accrochée, une pièce 59 ne peut plus tomber car les bossages accrochent le bourrelet. D'autre part, vu la longueur des jambes, 2 cm, qui leur donne une certaine élasticité, les tolérances de fabrication sur les surépaisseurs du bourrelet et des bossages peuvent être de l'ordre de 0,05 mm, ce qui peut être obtenu dans l'extrusion de matières plastiques classiques.The top 66 has two recesses 68 and 69 respectively on each side of the base of the ridge 67. The ridge 67 has a section such that the rider of the rule 50 overlaps it by clamping it between the bosses 54 and 55. The top of the ridge 67 has the shape of a bead 70 which is locked between the bosses 54 and 55, the apex 53 and the inner flanks of the rider of the rule 50 when it is placed on the part 59. As an indication, the the thickness of the ridge 67 may be 3.65 mm in its lower and middle part, and 3.85 mm at the height of the bead 70, which therefore has an additional thickness of 0.1 mm on each side. This extra thickness is equal to that of the bosses 54 and 55 inside the legs 51 and 52 of the rule. Once hooked, a piece 59 can no longer fall because the bosses catch the bead. On the other hand, given the length of the legs, 2 cm, which gives them a certain elasticity, the manufacturing tolerances on the extra thicknesses of the bead and bosses can be of the order of 0.05 mm, which can be obtained in the extrusion of conventional plastics.

Les extrémités inférieures des jambes 51 et 52 de la règle 50 viennent se loger dans les creux 68 et 69. Ainsi, la règle repose sur la pièce d'assemblage non seulement par son sommet, mais par les extrémités de ses jambes.The lower ends of the legs 51 and 52 of the rule 50 are housed in the recesses 68 and 69. Thus, the rule rests on the connecting piece not only by its top, but by the ends of its legs.

L'ouverture des creux 68 et 69 peut éventuellement être légèrement resserrée et l'extrémité inférieure des jambes 51 et 52 peut avoir la forme d'un bourrelet pour constituer un moyen de verrouillage supplémentaire.The opening of the recesses 68 and 69 may possibly be slightly tightened and the lower end of the legs 51 and 52 may have the shape of a bead to constitute an additional locking means.

Des plaques verticales 71 et 72 s'élèvent à partir des flancs externes des jambes 60 et 61 de la pièce 59. Les plaques 71 et 72 sont perpendiculaires à la crête 67, leur côté supérieur est horizontal et au même niveau que le bord horizontal de la crête 67. Les plaques 71 et 72 s'élèvent dans la partie médiane des flancs externes des jambes 60 et 61, sur la plus grande partie de la largeur desdits flancs. Cependant, les côtés verticaux des plaques 71 et 72 voisins de la crête 67 sont espacés de celle-ci d'une distance permettant d'assembler une règle 50 sur la crête 67. Sur une de leurs faces, les plaques 71 et 72 comportent deux petits rebords horizontaux en saillie 73 et 74, au même niveau que le fond des creux 68 et 69. L'épaisseur des plaques 71 et 72 est légèrement supérieure à celle de la crête 67 de façon que les extrémités des jambes 51 et 52 non maintenues comme dans les creux 68 et 69, soient en appui sur les flancs des plaques 71 et 72. En pratique, le sommet des plaques 71 et 72 peut avoir sensiblement la même forme et les mêmes dimensions que le bourrelet 70.Vertical plates 71 and 72 rise from the external flanks of the legs 60 and 61 of the part 59. The plates 71 and 72 are perpendicular to the ridge 67, their upper side is horizontal and at the same level as the horizontal edge of the ridge 67. The plates 71 and 72 rise in the middle part of the outer flanks of the legs 60 and 61, over the greater part of the width of said flanks. However, the vertical sides of the plates 71 and 72 adjacent to the crest 67 are spaced therefrom by a distance making it possible to assemble a rule 50 on the crest 67. On one of their faces, the plates 71 and 72 have two small horizontal projecting edges 73 and 74, at the same level as the bottom of the hollows 68 and 69. The thickness of the plates 71 and 72 is slightly greater than that of the crest 67 so that the ends of the legs 51 and 52 are not maintained as in the recesses 68 and 69, are supported on the sides of the plates 71 and 72. In practice, the top of the plates 71 and 72 may have substantially the same shape and the same dimensions as the bead 70.

Sensiblement dans le même plan vertical que les plaques 71 et 72, une barre horizontale 75 relie les flancs intérieurs des jambes 60 et 61 pour empêcher lesdites jambes de s'écarter sous l'effet d'une force verticale, le poids de la règle vibrante par exemple.Substantially in the same vertical plane as the plates 71 and 72, a horizontal bar 75 connects the inner sides of the legs 60 and 61 to prevent said legs from spreading under the effect of a vertical force, the weight of the vibrating rule for example.

Cette configuration des pièces 59 permet de les employer à la fois comme pièces de soutien des parties de règle 50 et comme pièces pour réaliser les points de croisement.This configuration of the parts 59 makes it possible to use them both as supporting parts of the rule parts 50 and as parts for making the crossing points.

La pièce 76 de la fig. 3 constitue une variante de la pièce d'assemblage 59 de la fig. 2, en ce que le V de celle-ci est ouvert jusqu'à 180°. Elle comporte une plaque horizontale 77 de forme carrée. Elle est surmontée d'une crête 78 identique à la crête 67 de la fig. 2. La crête 78 relie les milieux de deux côtés opposés de la plaque 77. La plaque 77 comporte deux bossages longitudinaux 79 et 80, parallèles à la crête 78, de façon à former deux creux 81 et 82 respectivement de chaque côté de la crête 78. Deux portions 83 et 84 de crête telle que la crête 78 s'élèvent sur la ligne rejoignant les milieux des deux autres côtés opposés de la plaque 77. Lesdites portions 83 et 84 sont écartées de la crête 78 d'une distance qui permet d'assembler la règle 50 à cheval sur la crête 78. Leurs autres extrémités sont à la verticale des côtés de la plaque 77. Les côtés de la plaque 77 comportent en leur milieu des méplats horizontaux tels que 85 et 86, seuls visibles à la fig. 3, de niveau légèrement inférieur au niveau de la plaque 77. La face inférieure de la plaque 77 comporte des pieds en V inversé aux jambes très courtes. Les pièces 76 sont prévues pour réaliser des dallages moins épais qu'avec les pièces 59 ou pour mettre toutes les pièces d'assemblage à niveau sur un sol inégal. Comme les pièces 59, les pièces 76 servent aussi à réaliser les points de croisement.The part 76 of fig. 3 constitutes a variant of the assembly part 59 of FIG. 2, in that the V thereof is open up to 180 °. It comprises a horizontal plate 77 of square shape. It is surmounted by a crest 78 identical to the crest 67 in FIG. 2. The crest 78 connects the midpoints of two opposite sides of the plate 77. The plate 77 has two longitudinal bosses 79 and 80, parallel to the crest 78, so as to form two recesses 81 and 82 respectively on each side of the crest 78. Two portions 83 and 84 of crest such as crest 78 rise on the line joining the midpoints of the two other opposite sides of the plate 77. Said portions 83 and 84 are spaced from crest 78 by a distance which allows to assemble the rule 50 straddling the ridge 78. Their other ends are vertical to the sides of the plate 77. The sides of the plate 77 have in their middle horizontal flats such as 85 and 86, only visible at the fig. 3, level slightly below the level of the plate 77. The underside of the plate 77 has V-shaped feet shed with very short legs. The parts 76 are provided for making slabs that are thinner than with the parts 59 or for leveling all the assembly parts on uneven ground. Like parts 59, parts 76 also serve to make the crossing points.

Lorsqu'on ancre les pièces 76 dans le béton de scellement, celui-ci affleure la surface supérieure de la plaque 77. Du béton risquerait donc de couler sur la plaque 77, dans les creux 81 et 82 ou à proximité des bases des portions 83 et 84. Au moment du coulage du béton de dallage, il faut pouvoir enlever les règles 50, pour laisser passer les bétonnières... Les bavures de béton dans les creux 81 et 82 renderaient le repositionnement de la règle 50 difficile, voire impossible sans un nettoyage préalable de la plaque 77. Les méplats 85 et 86 sont prévus pour éviter ce genre d'incident.When the parts 76 are anchored in the sealing concrete, the latter is flush with the upper surface of the plate 77. Concrete would therefore risk pouring onto the plate 77, in the hollows 81 and 82 or near the bases of the portions 83 and 84. When pouring the paving concrete, it is necessary to be able to remove the rules 50, to let the concrete mixers pass ... The concrete burrs in the hollows 81 and 82 would make the repositioning of the rule 50 difficult, even impossible without cleaning the plate 77 beforehand. The flats 85 and 86 are provided to avoid this type of incident.

Le dispositif selon l'invention résout efficacement le problème de l'étanchéité des joints. En effet, lorsque le béton opère son retrait, il pince les deux oreilles en queue d'aronde 58 dont chaque côté de la règle 50 est muni, si bien qu'on a une étanchéité efficace à deux étages. Cette traction sur les quatre oreilles 58 peut aller jusqu'à la rupture du sommet 53 et du voile 56 qui, à cet effet, sont prévus moins épais que le sommet 57 et les oreilles 58. De plus, la fissure de retrait n'est dirigée que sur les 5 cm supérieurs du dallage correspondant à la hauteur de la règle 50. En dessous, il se produit une fissure de retrait anarchique qui assure un clavetage parfait des panneaux de dallage.The device according to the invention effectively solves the problem of sealing the joints. Indeed, when the concrete operates its withdrawal, it pinches the two ears dovetail 58 which each side of the rule 50 is provided, so that there is an effective two-stage seal. This traction on the four ears 58 can go as far as breaking the top 53 and the veil 56 which, for this purpose, are provided thinner than the top 57 and the ears 58. In addition, the withdrawal crack is not directed only on the top 5 cm of the paving corresponding to the height of the rule 50. Below, there is an anarchic shrinkage crack which ensures perfect keying of the paving panels.

En outre, le dispositif selon l'invention permet de réaliser des dallages allant de 6 cm à 20 cm d'épaisseur selon qu'on utilise les pièces d'assemblage 76 ou les pièces d'assemblage 59.In addition, the device according to the invention makes it possible to produce pavements ranging from 6 cm to 20 cm thick depending on whether the connecting pieces 76 or the connecting pieces 59 are used.

A la fig. 4, on a montré, en coupe, une variante de la règle de la fig. 1. D'une manière générale, on a, à la fig. 4, conservé les mêmes références numériques pour désigner les mêmes parties. A la fig. 4, la crête 50 est prolongée vers le bas par deux jambes 51 ' et 52', jointes à leurs extrémités supérieures par le sommet 53. Les flancs intérieurs des jambes 51' et 52' comportent les bossages 54 et 55 à une certaine distance du sommet 53. Au-dessus du sommet 53, on retrouve la poutre creuse formée des parties 56 à 58. Dans la variante de la fig. 4, les oreilles inférieures 58 sont à la hauteur du sommet 53, mais cela n'est pas obligatoire. Dans la variante, les oreilles en queue d'aronde 87 d'une troisième paire sont prévues de chaque côté des extrémités inférieures des jambes 51' et 52'.In fig. 4, we have shown, in section, a variant of the rule of FIG. 1. In general, we have, in fig. 4, kept the same reference numbers to designate the same parts. In fig. 4, the crest 50 is extended downward by two legs 51 'and 52', joined at their upper ends by the apex 53. The inner flanks of the legs 51 'and 52' include the bosses 54 and 55 at a certain distance from the vertex 53. Above vertex 53, there is the hollow beam formed by parts 56 to 58. In the variant of FIG. 4, the lower ears 58 are at the height of the apex 53, but this is not compulsory. In the variant, the dovetail ears 87 of a third pair are provided on each side of the lower ends of the legs 51 'and 52'.

Cette structure à trois paires de nervures étagées améliore encore la rigidité de la règle avec pour conséquence soit de permettre l'augmentation de l'espacement entre les pièces d'assemblage, soit de supporter des règles vibrantes plus lourdes. Elle assure également une meilleur étanchéité.This structure with three pairs of stepped ribs further improves the rigidity of the rule with the consequence either of allowing the spacing between the joining parts to be increased, or of supporting heavier vibrating rules. It also provides better sealing.

La pièce d'assemblage de la fig. 5 est une variante de celle de la fig. 3 et est prévue pour être utilisée avec la règle de la fig. 4.The assembly part of fig. 5 is a variant of that of FIG. 3 and is intended to be used with the ruler of FIG. 4.

A la fig. 5, où l'on a utilisé les mêmes références numériques qu'à la fig: 3, pour désigner les mêmes parties, on retrouve les éléments 77, 78, 83, 84 et 86. Par contre. les éléments 79 à 82 sont supprimés et remplacés, sur la face supérieure de la plaque 77, par deux butées linéaires 88 et 89 qui sont parallèles à la crête 78 et respectivement écartées de celle-ci d'une distance égale à la distance entre l'extrémité externe d'une oreille 87 de la face interne d'une jambe 51' ou 52'. Entre chaque butée 88 ou 89 et la crête 78, la face supérieure de la plaque 77 a une profil qui correspond au profil inférieur des oreilles 87. Dans l'exemple de réalisation montré, ce sont deux plans inclinés 90 et 91.In fig. 5, where the same reference numbers have been used as in FIG: 3, to designate the same parts, there are the elements 77, 78, 83, 84 and 86. On the other hand. the elements 79 to 82 are deleted and replaced, on the upper face of the plate 77, by two linear stops 88 and 89 which are parallel to the crest 78 and respectively spaced from the latter by a distance equal to the distance between l 'external end of an ear 87 of the internal face of a leg 51' or 52 '. Between each stop 88 or 89 and the crest 78, the upper face of the plate 77 has a profile which corresponds to the lower profile of the ears 87. In the embodiment shown, these are two inclined planes 90 and 91.

Ainsi, à chaque pièce d'assemblage, les bas des jambes 51' et 52' sont maintenus serrés par les butées 88 et 89, ce qui coince les bossages 54 et 55 sous le bourrelet de la crête 78.Thus, at each assembly part, the bottoms of the legs 51 ′ and 52 ′ are held tight by the stops 88 and 89, which jams the bosses 54 and 55 under the bead of the ridge 78.
