Abstract

Device permitting the construction of floating floors (2) intended to provide active or passive filtering of vibrations. The invention relates to low-frequency resilient (elastic) spot-type supports consisting of helical-spring boxes (1). These spring boxes (1) are positioned at the time of casting the floor (2), the springs (5), which are prestressed beforehand, are used for raising the work by means of progressive release. The spring boxes (1) are accessible, demountable and adjustable for levelling the floor (2). <IMAGE>

Description

Avec les techniques de constructions modernes (diminution des épaisseurs de planchers, augmentation des portées, développement des murs rideaux, généralisation des équipements d'air conditionne.... ) les problèmes de transmission de vibrations se sont développés.With modern construction techniques (reduction in floor thicknesses, increased spans, development of curtain walls, generalization of air conditioning equipment, etc.) the problems of transmission of vibrations have 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. Ce principe permet, par ailleurs, d'installer des machines trépidantes sur des dalles suspendues, filtrant ainsi la vibration à la source.When these vibratory and acoustic nuisances are deemed unacceptable for the use of a room, a machine or equipment, it is possible to globally separate the floors concerned. This principle also makes it possible to install hectic machines on suspended slabs, thus filtering the vibration at the source.

La présente invention concerne un dispositif permettant la mise en oeuvre de tels planchers flottants. Ceux-ci sont constitués d'une dalle béton reposant sur des boîtes à ressort hélicoïdal, dimensionnées en fonction des charges statiques, des surcharges et des excitations à filtrer.The present invention relates to a device allowing the implementation of such floating floors. These consist of a concrete slab resting on helical spring boxes, dimensioned according to static loads, overloads and excitations to be filtered.

La technique antérieure à la présente invention pour la mise en oeuvre de dalles flottantes consiste à couler le béton sur des plaques ou des éléments en matières de synthèse aux caractéristiques élastiques limitées et mal connues, le joint périphérique du local étant réalisé dans les mêmes matériaux. Cette technique ne permet pas d'obtenir des fréquences propres d'installation suffisamment basses pour garantir un bon filtrage. Les éléments élastiques ne sont ni visitables, ni interchangeables, donc, difficilement réglables. Par ailleurs, lors de la mise en oeuvre, des "ponts rigides" se créent entre plancher primaire et dalle flottante. Ces points durs favorisent la transmission solidienne.The technique prior to the present invention for the implementation of floating slabs consists in pouring the concrete onto plates or elements made of synthetic materials with limited and poorly understood elastic characteristics, the peripheral joint of the room being made of the same materials. This technique does not make it possible to obtain sufficiently low natural installation frequencies to guarantee good filtering. The elastic elements are neither visitable nor interchangeable, therefore, difficult to adjust. Furthermore, during installation, "rigid bridges" are created between the primary floor and the floating slab. These hard points favor solidary transmission.

Le présent procédé offre l'avantage de garantir des fréquences propres pratiques d'installation conformes aux fréquences théoriques déterminées par le calcul :

  • 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 present method offers the advantage of guaranteeing practical installation natural frequencies in accordance with the theoretical frequencies determined by the calculation:
  • The characteristics of the coil spring are in fact known and stable over time.
  • The floating floor of the present invention is completely separated from the primary slab.

Les boîtes à ressort hélicoïdal sont visitables et réglables et permettent donc de faire varier les caractéristiques de la suspension en fonction d'une éventuelle évolution des charges.The helical spring boxes can be visited and adjusted and therefore make it possible to vary the characteristics of the suspension according to a possible evolution of the loads.

Le plancher flottant de la présente invention peut être destiné 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 floating floor of the present invention may be intended to provide either "active" filtering (for example air conditioning technical room) or "passive" filtering (for example protection against acoustic and vibration nuisances of metropolitan networks , rail and road or vis-à-vis various technical equipment).

La présente invention décrit un dispositif qui permet d'obtenir, par des appuis ponctuels, des réglages en basse fréquence et donc des performances de filtrage très élevées, tout en conservant pour l'entreprise de génie civil une facilité de mise en oeuvre.The present invention describes a device which makes it possible to obtain, by occasional presses, low frequency settings and therefore very high filtering performance, while retaining ease of use for the civil engineering company.

Une répartition non uniforme des appuis élastiques permet de reprendre aisément des charges ponctuelles (machines) ou des charges périphériques (cloisons) sans augmenter les contraintes dans le plancher flottant. Les 3 figures annexées décrivent la présente invention :

  • La figure 1 représente la boîte à ressort (vide) lors de la coulée du béton.
  • La figure 2 illustre la mise en place du ressort précontraint après séchage de la dalle.
  • La figure 3 montre l'opération de levage et de réglage du plancher.
A non-uniform distribution of the elastic supports makes it possible to easily take up point loads (machines) or peripheral loads (partitions) without increasing the stresses in the floating floor. The 3 attached figures describe the present invention:
  • Figure 1 shows the spring box (empty) when pouring concrete.
  • Figure 2 illustrates the installation of the pre-stressed spring after drying of the slab.
  • Figure 3 shows the floor lifting and adjusting operation.

Le dispositif de la présente invention est donc constitué de boîtes à ressort hélicoïdal ① intégrées au plancher ② lors de la coulée du béton, la dalle primaire ③ servant de coffrage. Le sol est recouvert de deux films polyéthylène avant la coulée pour éviter toute liaison parasite. Des ancrages ④ prévus sur les boîtes à ressort permettent de solidariser celles-ci avec le béton et son armature. Un joint polystyrène provisoire en périphérie du local sera détruit avant le levage de l'ouvrage.The device of the present invention therefore consists of helical spring boxes ① integrated into the floor ② during the pouring of the concrete, the primary slab ③ serving as formwork. The ground is covered with two polyethylene films before pouring to avoid any parasitic bond. Anchors ④ provided on the spring boxes make it possible to secure these with the concrete and its reinforcement. A temporary polystyrene joint at the periphery of the room will be destroyed before the lifting of the structure.

La libération du ressort ⑤ préalablement précontraint permet le levage progressif du plancher après séchage. Les boîtes à ressort, visitables et démontables en vue d'une évolution des charges portées, permettent, par un réglage de la plaque d'assise, ⑥ à l'aide de la vis ⑦ une mise à niveau de l'ouvrage.The release of the pre-stressed spring permet allows the progressive lifting of the floor after drying. The spring boxes, which can be visited and dismantled for the purpose of changing the loads carried, allow, d'ass by adjusting the seat plate, ⑥ using the screw ⑦ to level the structure.

Le ressort et l'intérieur des boîtes à ressort sont protégés contre la corrosion afin de garantir une bonne tenue du système dans le temps.The spring and the interior of the spring boxes are protected against corrosion in order to guarantee a good resistance of the system over time.

La boîte à ressort est operculée par un couvercle ⑧ dans le plan du sol.The spring box is sealed with a cover ⑧ in the ground plane.
