Description
Avec les techniques de constructions modernes des bâtiments (diminution des épaisseurs des planchers, augmentation des portées, développement des murs rideaux, généralisation des équipements d'air conditionné ...) les problèmes de transmission de vibrations se sont développés.With the techniques of modern building constructions (reduction of the thickness of the floors, increase of the ranges, development of the curtain walls, generalization of the equipment of air conditioning ...) the problems of transmission of vibrations developed.
Lorsque ces nuisances vibratoires et acoustiques sont jugées inacceptables pour l'utilisation d'un local, d'une machine ou d'un équipement, il est possible de désolidariser globalement les planchers concernés.When these vibratory and acoustic nuisances are deemed unacceptable for the use of a room, machine or equipment, it is possible to separate the floors concerned.
Ce principe permet par ailleurs d'installer des machines trépidantes sur des dalles suspendues, filtrant ainsi les vibrations à la source.This principle also makes it possible to install hectic machines on suspended slabs, thus filtering the vibrations at the source.
La présente invention concerne un dispositif permettant la mise en oeuvre rapide de tels planchers flottants, constitués d'une dalle béton reposant sur des ressorts hélicoïdaux, dimensionnés en fonction des charges statiques, des surcharges et des excitations à filtrer.The present invention relates to a device for the rapid implementation of such floating floors, consisting of a concrete slab resting on helical springs, sized according to the static charges, overloads and excitations to be filtered.
La technique antérieure à la présente invention pour la mise en oeuvre de dalles flottantes sur appuis basse fréquence est décrite dans le brevet d'invention de Alain LACROIX, dirigeant de la société GERB SA, délivré le 13/01/1999 sous la référence EP 0610634.The technique prior to the present invention for the implementation of floating slabs on low frequency supports is described in the patent of Alain LACROIX, leader of the company GERB SA, issued on 13/01/1999 under the reference EP 0610634 .
Elle nécessite d'installer des réservations préalablement au coulage de l'ouvrage. Après séchage, le levage du plancher flottant requiert l'utilisation d'un outillage spécifique de libération et de réglage des boîtes à ressorts.It requires to install reservations prior to pouring the structure. After drying, the lifting of the floating floor requires the use of specific tools for the release and adjustment of the spring boxes.
Cette technique est particulièrement adaptée aux planchers de géométrie complexe et lorsque les descentes de charges sont mal connues ou évolutives.This technique is particularly suitable for floors with complex geometry and when the descents of charges are poorly known or evolving.
La présente invention concerne un dispositif permettant la mise en oeuvre de dalles béton armé de géométrie simple en une seule opération.The present invention relates to a device for the implementation of reinforced concrete slabs of simple geometry in a single operation.
Le dispositif selon l'invention est défini dans la revendication 1 en annexe. Des caractéristiques avantageuses sont définies dans les revendications dépendantes.The device according to the invention is defined in claim 1 in the appendix. Advantageous features are defined in the dependent claims.
Le plancher est coulé en place dans un bac acier collaborant, équipé d'appuis ponctuels élastiques à basse fréquence propre verticale de types ressorts hélicoïdaux précontraints.The floor is poured into place in a collaborating steel tank, equipped with vertical clean low frequency elastic point supports of prestressed coil spring types.
La valeur de cette précontrainte permet de garantir l'immobilité de l'ouvrage pendant sa mise en oeuvre sans mouvement parasite de l'ouvrage.The value of this prestressing ensures the immobility of the structure during its implementation without parasitic movement of the structure.
L'obtention de la charge totale entraîne la libération automatique du système élastique qui joue alors son rôle de filtrage basse fréquence.Obtaining the total charge causes the automatic release of the elastic system which then plays its role of low frequency filtering.
L'utilisation de bacs aciers ondulés permet de réduire la hauteur du plancher suspendu, les ressorts hélicoïdaux étant logés dans les ondulations.The use of corrugated steel bins reduces the height of the suspended floor, the coil springs being housed in the corrugations.
Cette technique particulièrement économique permet d'obtenir des fréquences propres d'installation suffisamment basses pour garantir un bon filtrage, conforme au calcul théorique :
- Les caractéristiques du ressort hélicoïdal sont, en effet, connues et stables dans le temps.
- Le plancher flottant de la présente invention est totalement désolidarisé de la dalle primaire.
- The characteristics of the coil spring are, in fact, known and stable over time.
- The floating floor of the present invention is totally disassociated from the primary slab.
La présente invention peut être destinée à assurer, soit un filtrage « actif » (par exemple local technique de climatisation), soit un filtrage « passif » (par exemple protection vis-à-vis des nuisances acoustiques et vibratoires des réseaux métropolitain, ferroviaire et routier ou vis-à-vis d'équipements techniques divers).The present invention may be intended to ensure either an "active" filtering (for example a technical room for air-conditioning) or a "passive" filtering (for example protection against acoustic and vibratory nuisances of the metropolitan, railway and road or other technical equipment).
Par l'utilisation de ressorts hélicoïdaux basses fréquences précontraints, la présente invention permet d'obtenir, après leur libération, un filtrage très élevé tout en conservant, pour l'entreprise de génie civil, une grande facilité de mise en oeuvre.By the use of prestressed low-frequency coil springs, the present invention makes it possible to obtain, after their release, a very high filtering while at the same time preserving, for the civil engineering firm, a great ease of implementation.
La concentration et le choix des ressorts hélicoïdaux en périphérie de plancher permettent l'élévation de murs d'isolation, sans augmenter les contraintes dans le plancher flottant.The concentration and choice of coil springs at the edge of the floor allow the elevation of insulation walls, without increasing the stresses in the floating floor.
Les figures annexées décrivent la présente invention :
- La figure 1 représente une vue en coupe du dispositif.
- La figure 2 représente une vue en coupe de gauche selon la figure 1.
- La figure 3 représente une vue de dessus de l'appui ponctuel élastique.
- Figure 1 shows a sectional view of the device.
- FIG. 2 represents a view in left section according to FIG.
- Figure 3 shows a top view of the resilient point support.
Les figures 1 à 3 représentent le dispositif avant coulage de la dalle.Figures 1 to 3 show the device before pouring the slab.
Les figures 4 à 6 sont semblables aux figures 1 à 3, mais après coulage de la dalle, donc après libération de la précontrainte provisoire.Figures 4 to 6 are similar to Figures 1 to 3, but after pouring of the slab, so after release of the provisional prestressing.
Le dispositif de la présente invention est donc constitué d'un bac acier collaborant (1) supporté par des ressorts provisoirement précontraints (2) par un câble d'acier (3), fixés sous le bac acier.The device of the present invention therefore consists of a cooperating steel tray (1) supported by springs provisionally prestressed (2) by a steel cable (3) , fixed under the steel tray.
Des profilés transversaux (4), fixés sous le bac acier, interdisent sa déformation. Un joint polystyrène (5) provisoire, en périphérie du local, sera détruit après séchage de l'ouvrage.Transverse profiles (4) , fixed under the steel tray, prevent its deformation. A temporary polystyrene gasket (5) , on the periphery of the room, will be destroyed after drying of the structure.
Les ressorts ainsi que les dispositifs de fixation et de précontrainte provisoire sont protégés contre la corrosion, afin de garantir une bonne tenue du système dans le temps.The springs as well as the fixing and provisional prestressing devices are protected against corrosion, in order to guarantee a good stability of the system over time.
