Abstract
Description
L'objet de l'invention concerne un premier certificat d'addition apporté au brevet NO 80 26622 du 12 Décembre 1980 pour un élément préfabriqué modulaire pour la confection de murs de soutènement. The object of the invention relates to a first certificate of addition brought to patent NO 80 26622 of December 12, 1980 for a modular prefabricated element for the construction of retaining walls.
L ' expèrience a démontré que l'élément tel qu'il était décrit dans le brevet principal présentait des imperfections pour 1 'écoulement des eaux, pour sa préfabrication et sa manutention. Experience has shown that the element as described in the main patent had imperfections for the flow of water, for its prefabrication and its handling.
Le dispositif suivant l'invention supprime ces inconvénients et permet un écoulement rationnel et accéléré des eaux, une préfabrication économique et une manutention mécanique ou manuelle. The device according to the invention eliminates these drawbacks and allows rational and accelerated flow of water, economical prefabrication and mechanical or manual handling.
Il se caractérise par la combinaison des profilages et prolongement des encoches latérales hautes et basses, par le positionnement d'un fer ou étrier de manutention dans le dit prolongement de 1' encoche et par la confection d'un chanfrein sur ses faces transversales avant. It is characterized by the combination of profiling and extension of the high and low lateral notches, by the positioning of a handling iron or stirrup in said extension of the notch and by the making of a chamfer on its front transverse faces.
Sur les dessins annexés donnés à titre d'exemple non limitatif d'une des formes de réalisation de l'objet de l'invention:
La figure 1 montre l'élément vu en perspective,
La figure 2 représente la clavette.In the appended drawings given by way of nonlimiting example of one of the embodiments of the subject of the invention:
Figure 1 shows the element seen in perspective,
Figure 2 shows the key.
La figure 3 montre à une échelle différente les encoches modifiées hautes et basses latérales avec l'étrier de levage de l'encoche haute. Figure 3 shows on a different scale the modified upper and lower lateral notches with the lifting bracket of the upper notch.
La figure 4 représente les encoches hautes et basses dans la face arrière. FIG. 4 represents the high and low notches in the rear face.
Les figures 5 et 6 représentent les détails des chanfreins. Figures 5 and 6 show the details of the chamfers.
L'élément est constitué par un module standardisé juxtaposable et superposable en béton avec armatures de structuration. The element is made up of a standardized juxtaposed and stackable concrete module with structuring reinforcement.
Il comporte des parements latéraux 1, 2 pourvu d'encoches hautes et basses 3, 4, 5, 6. Sur chacun d'eux, les encoches latérales se prolongent par des échancrures axiales 7, 8, 9, 10 et autres, formant chacune des "barbacanes" ou orifices d récoulement des eaux de drainage situées aux points bas et hauts. It has lateral facings 1, 2 provided with high and low notches 3, 4, 5, 6. On each of them, the lateral notches are extended by axial notches 7, 8, 9, 10 and others, each forming "barbacans" or drainage water outlets located at the low and high points.
Les encoches supèrieures 7, 8 comportent un fer 11 noyé dans la masse servant à la manutention par des crochets d'une tige de fer ou autre. The upper notches 7, 8 comprise an iron 11 embedded in the mass used for handling by hooks of an iron rod or the like.
Le parement tranversal 12 comporte des encoches hautes et basses 14, 15 (Fig 4) de drainage. La face transversale avant 13 (Fig. 5, 6) est pourvue de chanfreins périphériques 16, 17 les renforçant, évitant l ' échancrure des aretes enjolivant la face. The transverse facing 12 has high and low notches 14, 15 (Fig 4) for drainage. The front transverse face 13 (Fig. 5, 6) is provided with peripheral chamfers 16, 17 reinforcing them, avoiding the notching of the edges embellishing the face.
Cet élément améliore le drainage et l'écoulement des eaux provenant des terres soutenues et Fenêtrant à Z'intèrieiir du mur. Elle peut circuler et s'écouler par les orifices positionnés à cet effet, ces eaux sont évacuées à la base du mur par des barbacanes perçées à la demande sur les faces avant ou bien au niveau de la semelle. This element improves the drainage and the flow of water from the supported land and the window inside the wall. It can circulate and flow through the orifices positioned for this purpose, these waters are discharged at the base of the wall by barbican drilled on demand on the front faces or at the level of the sole.
Par contre, la mise en oeuvre de ces modules ainsi que leur remplissage avec des matériaux drainants se fait mécaniquement avec réduction de main-d'-oeuvre. On the other hand, the implementation of these modules as well as their filling with draining materials is done mechanically with reduction of manpower.
Les encoches hautes et basses servent à loger les clavettes 18 (Fig. 2). Le profil de ces modules , rectangulaires ou carrés est moulable et préfabricable en usine. The upper and lower notches are used to accommodate the keys 18 (Fig. 2). The profile of these modules, rectangular or square, can be molded and prefabricated in the factory.
Les faces latérales suivant les dimensions des modules peuvent comporter deux ou plusieurs encoches porte barettes, et se prolongeant par l'orifice d'écoulement des eaux. The lateral faces according to the dimensions of the modules may comprise two or more notches carrying bars, and extending by the water flow orifice.
C'est pourquoi les formes, dimensions et dispositions des différents éléments pourront varier dans la limite des équivalents comme d'ailleurs les matières utilisées pour leur fabrication sans changer pour cela la conception générale de l'invention qui vient d'etre décrite. This is why the shapes, dimensions and arrangements of the various elements may vary within the limit of the equivalents, as moreover the materials used for their manufacture without thereby changing the general conception of the invention which has just been described.
