Abstract
Description
La présente invention se refère aux joints de dilatation destinés à être placés dans des éléments de construction en béton en vue de constituer des joints de dilatation qui évitent que de telles constructions ne se fendent sous l'influence de la chaleur. Bien que l'invention soit plus particulièrement relative à un joint destiné aux travaux de sol, on pourrait fort bien sans sortir de l'invention utiliser un tel joint pour la réalisation de cloisons ou autres surfaces non horizontales. The present invention refers to expansion joints intended to be placed in concrete building elements in order to constitute expansion joints which prevent such constructions from cracking under the influence of heat. Although the invention relates more particularly to a joint intended for soil work, it could very well without departing from the invention use such a joint for the production of partitions or other non-horizontal surfaces.
Il existe beaucoup de dispositifs du genre en question prévus en matière plastique, en métal, etc... mais dans tous les cas, leur arête supérieure demeure à fleur de la surface de ltélément de béton après durcissement de celui-ci. L'arête considérée est donc visible ce qui peut nuire dans certains cas à l'esthétique des constructions, et peut poser des problèmes d'étanchéité. There are many devices of the kind in question provided in plastic, metal, etc., but in all cases, their upper edge remains flush with the surface of the concrete element after it has hardened. The edge considered is therefore visible, which can in some cases affect the aesthetics of the constructions, and can pose sealing problems.
Au contraire, conformément à l'invention, la partie supérieure du joint est détachable de manière qu'après prise du béton on puisse extraire ladite partie supérieure en vue de constituer une saignée libre qu'on peut remplir de mastic ou analogue par exemple pour éliminer toute trace du joint de dilation et rendre le joint étanche. On the contrary, in accordance with the invention, the upper part of the joint is detachable so that after setting of the concrete it is possible to extract said upper part in order to constitute a free groove which can be filled with mastic or the like for example to remove any traces of the expansion joint and seal the joint.
Dans une première forme d'exécution, la partie supérieure du joint est réunie à sa partie inférieure par l'intermédiaire de lignes de moindre résistance permettant un arrachage de ladite partie supérieure après séchage du béton. In a first embodiment, the upper part of the joint is joined to its lower part by means of lines of lesser resistance allowing tearing of said upper part after drying of the concrete.
Dans une seconde forme d'exécution, la partie supérieure du joint est assemblée préalablement à sa partie inférieure par simple encliquetage. In a second embodiment, the upper part of the joint is assembled before its lower part by simple snap-fastening.
Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer
Fig. 1 est une vue partielle en perspective d'un joint établi suivant une première variante de l'invention.The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing.
Fig. 1 is a partial perspective view of a joint established according to a first variant of the invention.
Fig. 2 illustre la manière dont le joint de figure 1 est inclus dans une dalle de béton. Fig. 2 illustrates the manner in which the joint in FIG. 1 is included in a concrete slab.
Fig. 3 montre comment après arrachage de la partie supérieure du joint, il existe au-dessus de sa partie restante une saignée libre. Fig. 3 shows how after tearing off the upper part of the seal, there exists above its remaining part a free groove.
Fig. 4 est une vue semblable à celle de figure 3 mais sur laquelle on a représenté un remplissage de la saignée libre. Fig. 4 is a view similar to that of FIG. 3 but on which a filling of the free groove is shown.
Fig. 5 est une vue éclatée en perspective des deux éléments d'un joint établi conformément à une variante de l'invention. Fig. 5 is an exploded perspective view of the two elements of a joint established in accordance with a variant of the invention.
Fig. 6 illustre le joint à l'état monté. Fig. 6 illustrates the seal in the assembled state.
Fig. 7 et 8 sont des vues semblables à celles de figures 2 et 4 mais qui sont relatives au joint de figure 6. Fig. 7 and 8 are views similar to those of FIGS. 2 and 4 but which relate to the joint of FIG. 6.
On a illustré en figure 1 un joint de dilatation selon l'invention affecté de la référence générale 1. Ce joint est établi sous la forme d'un caisson 2 comprenant deux cloisons verticales 3 et 4 et des cloisons transversales 5, 6, 7 destinées à raidir l'ensemble ce qui améliore la qualité de l'étanchéité. On observe qu'au-dessus de la cloison transversale 7, les deux cloisons 3 et 4 sont chacune pourvues d'une gorge longitudinale 3a respectivement 4a dont le fond se trouve à proximité immédiate de la face intérieure des cloisons verticales 3 et 4 de telle sorte que chacune de celles-ci comporte une zone de moindre résistance. Au-dessus de chacune des gorges 3a et 4a, les cloisons 3 et 4 divergent très légèrement en direction du haut et aboutissent à un voile transversal 8. Illustrated in Figure 1 an expansion joint according to the invention assigned the general reference 1. This joint is established in the form of a box 2 comprising two vertical partitions 3 and 4 and transverse partitions 5, 6, 7 intended to stiffen the assembly which improves the quality of the seal. It is observed that above the transverse partition 7, the two partitions 3 and 4 are each provided with a longitudinal groove 3a respectively 4a, the bottom of which is located in the immediate vicinity of the inner face of the vertical partitions 3 and 4 of such so that each of these has an area of least resistance. Above each of the grooves 3a and 4a, the partitions 3 and 4 diverge very slightly towards the top and lead to a transverse web 8.
A l'opposé de ce voile, l'arrête inférieure du joint 1 est pointue pour constituer une espèce de tranchant 9 dont le rôle sera mieux expliqué plus loin. Des ailettes latérales orientées obliquement en direction du haut partent de chacune des cloisons 3 et 4. Ces ailettes ont été référencées 3b, 3c, 3d respectivement 4b, 4c, 4d.Opposite this veil, the lower edge of the joint 1 is pointed to constitute a kind of cutting edge 9 whose role will be better explained below. Lateral fins oriented obliquely in the direction of the top leave from each of the partitions 3 and 4. These fins have been referenced 3b, 3c, 3d respectively 4b, 4c, 4d.
Lorsqu'une dalle ou autre élément de béton a été coulé, on enfonce le joint 1 dans le béton suivant la ligne désirée selon laquelle on veut réaliser un joint de dilatation jusqu'à ce que le voile 8 affleure substantiellement la surface supérieure 10a de la dalle 10. Après séchage du béton on conçoit aisément qu'on puisse saisir d'une manière ou d'une autre l'extrémité de la partie supérieure du joint située au
dessus des gorges 3a, 4a de manière à séparer les deux parties du joint par déchirage des zones de moindre résistance constituées par les gorges en question. La dalle se présente alors comme illustrée en figure 3, c'est-à-dire qu'au-dessus de la partie inférieure subsistante du joint se trouve une saignée libre 11.Comme illustré en figure 4, cette saignée peut être remplie de mastic ou analogue en vue de constituer un bourrage 12 qui d'une part fait fonction de joint de dilatation et d'autre part permet de dissimuler celui-ci.When a slab or other concrete element has been poured, the joint 1 is driven into the concrete along the desired line along which it is desired to make an expansion joint until the veil 8 is substantially flush with the upper surface 10a of the slab 10. After the concrete has dried, it is easy to see that we can grasp in one way or another the end of the upper part of the joint located at the
above the grooves 3a, 4a so as to separate the two parts of the joint by tearing of the zones of least resistance constituted by the grooves in question. The slab then appears as illustrated in FIG. 3, that is to say that above the remaining lower part of the joint is a free groove 11. As illustrated in FIG. 4, this groove can be filled with mastic or the like in order to constitute a stuffing 12 which on the one hand acts as an expansion joint and on the other hand makes it possible to conceal it.
On a illustré en figure 5 une autre forme d'exécution de l'invention dans laquelle le joint est composé de deux éléments, à savoir un joint proprement dit 13 et un profilé 14. Le joint 13 est fabriqué préférablement par extrusion d'une matière plastique alvéolaire de telle manière qu'il est réalisé sous la forme d'une croûte périphérique 13a et d'une âme 13b à structure plus souple que celle de la croûte. La encore, le joint comporte un tranchant inférieur 15 et des ailettes latérales 13c, 13d légèrement divergentes en direction du haut. Another embodiment of the invention is illustrated in FIG. 5 in which the seal is composed of two elements, namely a seal itself 13 and a profile 14. The seal 13 is preferably produced by extruding a material cellular plastic in such a way that it is produced in the form of a peripheral crust 13a and of a core 13b with a more flexible structure than that of the crust. Again, the seal has a lower cutting edge 15 and lateral fins 13c, 13d slightly divergent towards the top.
On observe qu'au niveau de son extrémité supérieure le joint 13 est pourvu de deux sillons longitudinaux référencés 13e, 13f. It is observed that at its upper end the seal 13 is provided with two longitudinal grooves referenced 13e, 13f.
Le second élément 14 est réalisé sous la forme d'un profilé creux affectant la forme générale d'un U dont les deux ailes 16, 17 présentent un écartement en gros égal à l'épaisseur du joint 13. Les deux ailes 16, 17 sont réunies par un voile transversal 18 qui peut éventuellement déborder au-delà de chacune de ces ailes. La face interne de chacune d'elles est pourvue d'un cordon 16a, 17a qui vient s'enclencher respectivement dans les sillons 13e, 13f du joint 13 lorsque ce dernier est engagé entre les ailes 16 et 17 du profilé 14. The second element 14 is produced in the form of a hollow profile having the general shape of a U, the two wings 16, 17 of which have a spacing roughly equal to the thickness of the seal 13. The two wings 16, 17 are joined by a transverse veil 18 which may possibly extend beyond each of these wings. The internal face of each of them is provided with a cord 16a, 17a which engages respectively in the grooves 13e, 13f of the seal 13 when the latter is engaged between the wings 16 and 17 of the profile 14.
Après cet assemblage, on obtient un joint composite du genre de celui illustré en figure 6. After this assembly, a composite joint of the kind illustrated in FIG. 6 is obtained.
Comme dans le cas du joint illustré en figure 1, le joint 13-14 est enfoncé dans la dalle 10 jusqu a ce que son voile transversal 18 affleure à peu près la face supérieure lOa de cette dalle. On peut alors extraire le profilé 14 qui s'arrache du joint 13 puisque celui-ci est très bien ancré dans le béton sec. La encore, on-obtient une saignée 11 qui peut être remplie de mastic 12. As in the case of the joint illustrated in FIG. 1, the joint 13-14 is pressed into the slab 10 until its transverse web 18 is roughly flush with the upper face 10a of this slab. We can then extract the profile 14 which tears from the seal 13 since the latter is very well anchored in dry concrete. Again, we get a groove 11 which can be filled with putty 12.
On comprend aisément que la seconde forme d'exécution de l'invention présente un intérêt tout particulier puisque le joint 13 peut être utilisé seul pour des applications bien spécifiques telles que joint de carrelage au ras de la surface du sol. It is easily understood that the second embodiment of the invention is of very particular interest since the joint 13 can be used alone for very specific applications such as tiling joint flush with the floor surface.
I1 doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'â titre d'exemple et qu'elle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents. I1 should also be understood that the foregoing description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalents.
