Description

ECRAN ANTI-hRUIT ABSORBANT EN ELEMENTS PREFABRIQUES
EN EE?0N ARME
La présente invention concerne un écran anti-bruit constitué de panneaux absorbants,maintenus par une ossature en béton armé formée d:él4ments préfabriqués.ABSORBENT ANTI-NOISE SCREEN IN PREFABRICATED ELEMENTS
IN EE? 0N WEAPON
The present invention relates to an anti-noise screen made up of absorbent panels, held by a reinforced concrete frame formed by: prefabricated elements.

I1 existe,certes,des réalisations en béton armé servant de support,ou formant écran, mais ces constructions sont en général massives,lourdes,construi-
place -tes sur # et équipées ensuite des panneaux anti-bruit, ce qui les rend très onéreuses.There are certainly realizations in reinforced concrete serving as a support, or forming a screen, but these constructions are generally massive, heavy, constructed
place them on # and then equip them with anti-noise panels, which makes them very expensive.

La présente invention ae caractérise par les moyens mis en oeuvre pris aussi bien dans leur ensemble que séparément, et plus particuliêrement par des dispositifs qui permettent de préfabriquer en usine des éléments de grandes dimensions,légers mais résistants et rigides, équipés en fond de moule des panneaux anti-bruit, donc entièrement terminés industriellement.Il suffit d'assembler sur place ces différents éléments et de les sceller.Quantaux panneaux anti-bruit,ils sont en mousse d'argile,en caissons de bois à persiennes,ou de tout autre conception. The present invention has been characterized by the means used, taken as a whole as well as separately, and more particularly by devices which make it possible to prefabricate in the factory elements of large dimensions, light but resistant and rigid, equipped at the bottom of the mold with anti-noise panels, therefore entirely finished industrially.Just assemble these elements on site and seal them. As for the noise-reduction panels, they are made of clay foam, wooden boxes with louvers, or any other design.

Les dessins annexés, donnés à titre d'exemple non limitatif,sont une des formes de réalisa- -tion de ltobjet de l'invention. The accompanying drawings, given by way of nonlimiting example, are one of the embodiments of the object of the invention.

La figure I est une vue en élévation d'un élément en béton armé, selon l'invention. Figure I is an elevational view of a reinforced concrete element according to the invention.

La figure 2 est une vue de profil, en coupe suivant I-2,de la figure I. Figure 2 is a side view, in section along I-2, of Figure I.

La figure 3 est une vue en plan,en coupe suivant 9-4 de la figure I. Figure 3 is a plan view, in section along 9-4 of Figure I.

La figure 4 montre une coupe longitudinale,en élévation, du scellement dans le sol d'un élément suivant figure I. Figure 4 shows a longitudinal section, in elevation, of the sealing in the ground of an element according to Figure I.

La figure 5 est une coupe du scellement dans le sol d'un élément vu de profii,suivant figure 2.  FIG. 5 is a section through the sealing in the ground of an element seen from profii, according to FIG. 2.

La figure 6 montre,en perspective,deux élément, juxtaposés de la suite d'un nombre quelconque des éléments formant l'ensemble de l'écran. Figure 6 shows, in perspective, two elements, juxtaposed following any number of elements forming the entire screen.

La figure 7 est une variante,avec profil parabolique des contreforts Chaque élément 10,en béton armé,se compose suivant figures I > 2et 3,d'un plan II renforcé par des contreforts 12 et 13 qui assurent la rigidité de l'en -semble et s'opposent aux renversementèi4 ou 15 > dus aux vents ou poussées quelconques,que doit supporter l'élé -ment fixé par scellement de sa partie inférieure I6et 17.  Figure 7 is a variant, with parabolic profile of the buttresses Each element 10, in reinforced concrete, consists according to Figures I> 2 and 3, of a plane II reinforced by buttresses 12 and 13 which ensure the rigidity of the - seems and oppose reversalsèi4 or 15> due to any winds or thrusts, which must bear the element -ment fixed by sealing its lower part I6et 17.

Ces éléments sont calculés en fonction des efforts à supporter et pour titre le plus léger possible, et dans ce but les contreforts peuvent être profilés en parabole 28 suivant figure 7,ce qui permet un gain de poids pourune résistance équivalente,et ajoute une allure d'esthétique appréciable. These elements are calculated according to the forces to be supported and for the lightest possible title, and for this purpose the buttresses can be profiled in a parabola 28 according to FIG. 7, which allows a gain in weight for an equivalent resistance, and adds a shape of aesthetic appreciable.

Les contreforts d'extrémités latérales I2,sont soumis à des contraintes inférieures à celles des contreforts 13 et sont donc plus étroits,mais étant jumelés aux éléments juxtaposés,la largeur totale reste sensiblement égale à celle des contreforts I3. The lateral end buttresses I2 are subjected to stresses lower than those of the buttresses 13 and are therefore narrower, but being combined with the juxtaposed elements, the total width remains substantially equal to that of the buttresses I3.

Deux des contreforts I3,forment en partie basse,pieds d'appui I6,sur le béton de propreté I8, suivant figures 4 et 5,alors que les autres contreforts ne se prolongent que par leur ferraillage I7 > qui servira d'ancrage,comme d'ailleurs les pieds d'appui I6, dans la semelle ou longrine 19.  Two of the buttresses I3 form, at the bottom, support legs I6, on the cleanliness concrete I8, according to FIGS. 4 and 5, while the other buttresses are extended only by their reinforcement I7> which will serve as anchoring, as moreover the support feet I6, in the sole or sill 19.

Chaque élément IO comporte en outre,des anneaux de levage 24 > des trous 25 pour assemblage par boulons de deux éléments. juxtaposés, et des douilles 26 pour fixation des étais 27 nécessaires pour le main -tien de l'ensemble pendant le coulage de la semelle 19. Each element IO further comprises lifting rings 24> holes 25 for assembly by bolts of two elements. juxtaposed, and sockets 26 for fixing the props 27 necessary for the main -tien of the assembly during the casting of the sole 19.

La face 20,plane,peut servir de support à un parement décoratif ou à des panneaux publicitaires avec, éventuellement, encadrement aluminium boulonné sur cette face.  The flat face 20 can serve as a support for a decorative facing or for advertising panels with, optionally, aluminum frame bolted to this face.

La face 2f regoit entre les contreforts les panneaux anti-bruit absorbants, en mousse d'argile, en caissons de bois à persiennes ,ou de tout autre conception. The face 2f receives between the buttresses the absorbent noise-absorbing panels, made of clay foam, wooden boxes with louvers, or any other design.

La fabrication en usine de ces éléments IO est trés simple.0n place dans le fond du moule les panneaux anti-bruit 22,on déploie dessus un film plasti -que 23 pour protéger,au au coulage du béton, la surface des mousses d'argiles qui ne seront scéllées que par les tran -ches, afin de permettre le changement des panneaux dété -riorés en cas d'accident.On place ensuite les armatures et on coule le béton.Le procédé est évidemment le même qu'il s'agisse de mousse d'argile ou d'autre panneaux anti bruit. The factory manufacture of these IO elements is very simple. Place the anti-noise panels 22 in the bottom of the mold, a plastic film 23 is deployed on them to protect, when the concrete is poured, the surface of the foams. clays which will be sealed only by the trenches, in order to allow the change of the deteriorated panels in the event of an accident. Then place the reinforcements and pour the concrete. The process is obviously the same as it is acts of clay foam or other noise barriers.

Il faut prévoir le moule pour une hauteur maximale,ce qui autorise des constructions d'éléments de hauteurs diverses en déplaçant le coffrage de la base. The mold must be provided for a maximum height, which allows constructions of elements of various heights by moving the formwork from the base.

Pour le montage,on coule la dalle de béton de propreté 18, sur laquelle on installe les éléments enti & -rement terminés.Oes éléments IO sont manutentionnés par les anneaux de levage 24,réglés en niveau et alignement au moyen de cales métalliques imputrescibles sous les pieds 16,boulonnés entre eux par les trous 25,et maintenus en position par des étais 27 fixés dans les douilles 26. For mounting, the cleanliness concrete slab 18 is poured, onto which the fully finished elements are installed. These IO elements are handled by the lifting rings 24, adjusted in level and alignment by means of rot-proof metal shims under the feet 16, bolted together by the holes 25, and held in position by stays 27 fixed in the sockets 26.

On place ensuite les armatures de la longrine I9 et les coffrages,d'ailleurs ces opérations peuvent titre éffectuées avant l'installation des éléments,puis on coule le béton et l'ensemble est terminé. We then place the reinforcement of the I9 sill and the formwork, moreover these operations can title effected before the installation of the elements, then the concrete is poured and the assembly is finished.

Les formes, dimensions et disposition des différents éléments en béton armé pourront varier dans la limite des équitalents,comme d'ailleurs les matériaux et conception des panneaux anti-bruit encastrés dans ces supports, sans changer pour cela la conception générale de l'invention quivient d'être décrite.  The shapes, dimensions and arrangement of the various reinforced concrete elements may vary within the limit of equivalents, as moreover the materials and design of the noise-reduction panels embedded in these supports, without changing the general design of the invention for this purpose. to be described.
