Abstract

The isolator for protecting a building (5) for seismic disturbances or vibrations comprises elastic spheres (1) which are positioned between a rigid cross beam of the building (3) and cup-shaped supports. The supports are situated above a layer of elastic material (6) which is placed on a foundation. The spheres may be either solid or hollow and act as dampers to suppress the vibrations.

Description

La présente invention a trait aux dispositifs destinés à amortir les secousses, vibrations1 tremblements etc.. produits par des séismes ou autres. The present invention relates to devices intended to dampen tremors, vibrations, tremors, etc. produced by earthquakes or the like.

Par sa fiabilité, et par la protection qu'elle offre aux constructions habitables et industrielles, la présente invention concerne principalement les secteurs du bâtiment et des travaux publics. By its reliability, and by the protection which it offers to habitable and industrial constructions, the present invention mainly concerns the building and public works sectors.

Les techniques antérieures consistent a
1) renforcer fortement les constructions au moyen de contreventements, poteaux, ceintures en béton armé exécutés suivant les règles parasismiques en vigueur (PS 69 en France).The prior techniques consist of
1) strongly reinforce the constructions by means of bracing, posts, reinforced concrete belts executed according to the seismic rules in force (PS 69 in France).

2) isoler la construction au moyen d'un assemblage de plaques d'acier et de caoutchouc, fixé dans ses parties basses et hautes à la construction lors d'un séisme ou autre, la plus grande partie de lténergie transmise par le sol est absorbée par cet assemblage et il en résulte un mouvement latéral de la construction. 2) isolate the construction by means of an assembly of steel and rubber plates, fixed in its lower and upper parts to the construction during an earthquake or other, most of the energy transmitted by the ground is absorbed by this assembly and this results in a lateral movement of the construction.

Le dispositif objet de l'invention (figure 1 coupe élèvation) est très différent, car il est basé, lui, sur un mouvement roulant associé à une déformation plastique due à des modes de travail combinés de la matière constituant les sphères (1) qui, elles, ne sont pas fixes, mais libres dans les alvéoles-cuvettes (2), ce qui leur autorise un certain débattement qui est fonction de l'intensité maximale que l'on se fixe. Ces alvéoles-cuvettes reposent, elles-mêmes, sur une plaque élastique (6), d'épais seur variable suivant les cas considérés. I1 est prévu des butées fixes(7) et déformables (8)+ certains cas ne nécessitent pas d'alvéoles-cuvettes. The device object of the invention (Figure 1 elevation section) is very different, because it is based on a rolling movement associated with plastic deformation due to combined working modes of the material constituting the spheres (1) which , they are not fixed, but free in the alveoli-bowls (2), which allows them a certain movement which is a function of the maximum intensity that is fixed. These cell-basins themselves rest on an elastic plate (6), of variable thickness depending on the cases considered. I1 is provided fixed stops (7) and deformable (8) + some cases do not require cell-bowls.

Ce dispositif d'une grande simplicité de mise en oeuvre peut être incorporé à la plupart des bâtiments, au moment de la construction, avec les moyens traditionnels les plus courants, sans qu'il soit nécessaire de faire appel à un matériel et à une main d'oeuvre sophistiqués : d'où fiabilité accrue. This device, which is very simple to implement, can be incorporated into most buildings, at the time of construction, with the most common traditional means, without the need for equipment and a hand. of sophisticated work: hence increased reliability.

Les réseaux d'alimentation et d'évacuation seront raccordés au nu extérieur du bâtiment par une partie souple destinée à accompagner les déformations provoquées par un séisme ou autres, sans pour cela cesser leur activité essentielle. The supply and evacuation networks will be connected to the exterior of the building by a flexible part intended to accompany deformations caused by an earthquake or others, without ceasing their essential activity.

Ce dispositif, objet de l'invention (fig. 1), est constitué par des sphères mobiles (1) de nombre et de dimensions variables, en matière élastique (caoutchouc, néoprène etc..) disposées dans des alvéoles-cuvettes(2) génèralement entre deux contreventements horizontaux rigidest7) (4), supportant la construction à protèger(l;) : lors des sollicitations diverses provoquées, par exemple par un séisme le mouvement roulant de ses ptres
conjugue à l'élasticité de la matière qui les cclstitue, adsorbe et dissi pe une grande partie de l'énergie transmise par le sol : la construction peut alors résister d'autant plus facilement au restant de l'énergie qu' elle aura été soumise, dans sa conception, aux règles parasismiques en vigueur.This device, object of the invention (fig. 1), is constituted by movable spheres (1) of variable number and dimensions, made of elastic material (rubber, neoprene etc.) arranged in cell-basins (2) generally between two horizontal braces rigidest7) (4), supporting the construction to be protected (l;): during various stresses caused, for example by an earthquake, the rolling movement of its rods
combines with the elasticity of the material which forms them, adsorbs and dissipates a large part of the energy transmitted by the soil: the construction can then resist all the more easily the rest of the energy that it will have been subjected , in its design, to the seismic rules in force.

Bien que le dispositif soit étudié pour que la construction revienne
toute seule, à sa place initiale, le fait d'avoir, par hasard, à la remet
tre en place après le séisme ( quelques centimètres), ne pose pas de pro
blème particulier : des moyens classiques suffisent.Although the device is studied so that the construction returns
all alone, in its original place, having, by chance, to put it back
be in place after the earthquake (a few centimeters), does not pose a problem
particular problem: conventional means are sufficient.

Cette invention n'est pas limitée à l'exemple décrit plus haut, car d'autres modifications peuvent y être apportées sans sortir de son cadre par exemple les sphères peuvent être en métal ou plastique dur et rigide, prises entre des coussinets en matière élastique ; il est possible aussi
d'intercaler ce dispositif entre deux étages d'un bâtiment.This invention is not limited to the example described above, because other modifications can be made without departing from its scope, for example the spheres can be made of hard or rigid metal or plastic, taken between pads of elastic material. ; it is also possible
to insert this device between two floors of a building.

Le dispositif, objet de l'invention, peut & re utilisé dans tous les cas, où il est nécessaire de protèger des constructions fixes ou mobiles,
des effets destructeurs produits par des séismes, ondes, vibrations, souffles, explosions etc.. The device, object of the invention, can be used in all cases, where it is necessary to protect fixed or mobile constructions,
destructive effects produced by earthquakes, waves, vibrations, breaths, explosions etc.
