Abstract

Device relating to a building resting and positioned on a plinth (2) anchored into the ground, via cylindrical journals (3) secured to its base (1), delimiting, with the pads (4) of the plinth (2) an annular space in which is housed an inflatable container (5) of toric shape filled with gas or liquid raising the base in the inflated position while centring the journal in the bore of the corresponding pad. This container is characterised in that it includes a cut between two flat ends (6) and (7) which provide sealing.

Description

DESCRIPTION
L'invention consiste en un dispositif de protection sismique.DESCRIPTION
The invention consists of a seismic protection device.

Dans le cadre de l'invention le bâtiment (par exemple maison d'habitation) comporte Fig. 1 une embase, (1) située au dessus d'un socle (2) rigide solidement ancré dans le sol et positionnée dans le plan horizontal par rapport à ce socle
La liaison entre l'embase (1) et le socle (2) se fait par l'intermédiaire d'un certain nombre de points d'appui et de centrage selon fig. 2 et 3 convenablement répartis pour équilibrer leurs charges respectives et caractérisés chacun comme suit: - Un tourillon cylindrique (3 ) est solidaire de 'embase (1).In the context of the invention, the building (for example a dwelling house) comprises FIG. 1 a base, (1) located above a rigid base (2) firmly anchored in the ground and positioned in the horizontal plane relative to this base
The connection between the base (1) and the base (2) is via a number of support and centering points according to fig. 2 and 3 suitably distributed to balance their respective loads and each characterized as follows: - A cylindrical journal (3) is secured to the base (1).

- Un plot (4) solidaire du socle (2) comporte un évidement cylindrique à l'intérieur duquel vient se loger le tourillon (3).- A stud (4) integral with the base (2) has a cylindrical recess inside which is housed the pin (3).

- Le tourillon 3 et l'alésage intérieur du plot (4) concentriques déterminent avec l'embase (1) et le socle (2) un espace annulaire de section rectangulaire à l'intérieur duquel on dispose un conteneur (5 ) de forme torique ouvrable entre les faces (6) et (7), en matériau souple de préférence en caoutchouc ou matière plastique gonflable de section tranversale circulaire, ovale ou rectangulaire défini de façon que les faces planes extrêmes (6) et (7) viennent en contact afin de bien remplir l'espace annulaire. Le conteneur étanche peut être rermpli de gaz ou de liquide. II comporte un tuyau d'amenée (8) du fluide.- The trunnion 3 and the internal bore of the concentric stud (4) determine with the base (1) and the base (2) an annular space of rectangular section inside which there is a container (5) of toroidal shape openable between the faces (6) and (7), made of flexible material, preferably rubber or inflatable plastic material of circular, oval or rectangular cross section defined so that the extreme planar faces (6) and (7) come into contact so to fill the annular space well. The sealed container can be filled with gas or liquid. It comprises a fluid supply pipe (8).

--Leplot comporte une ouverture (9) qui permet l'introduction du conteneur (5 )non gonflé. Une fois le conteneur en place l'ouverture est fermée par un bloc (10) dont le galbe correspond à l'alésage du plot (4) de façon à maintenir une parfaite symétrie dans toutes les directions axiales horizontales. Le bloc (10) comporte une rainure (li) permettant le passage du tuyau (8). Il est rendu solidaire du plot (4) par vissage, chevillage, insertion dans une rainure ou tout autre moyen mécanique usuel. --Leplot has an opening (9) which allows the introduction of the container (5) not inflated. Once the container in place the opening is closed by a block (10) whose curve corresponds to the bore of the stud (4) so as to maintain perfect symmetry in all the horizontal axial directions. The block (10) has a groove (li) allowing the passage of the pipe (8). It is made integral with the stud (4) by screwing, dowelling, insertion into a groove or any other usual mechanical means.

Tous les tuyaux (8) sont reliés entre eux par un collecteur (12) de façon à avoir une pression égale dans chaque conteneur. Le collecteur (12) est alimenté par une pompe, un compresseur ou un accumulateur à travers un clapet de non retour. Un manostat branché sur le collecteur (12) permet d'en maintenir la pression à la valeur désirée. Il déclenche une alarme en cas de baisse de pression anormale.All the pipes (8) are interconnected by a manifold (12) so as to have an equal pressure in each container. The collector (12) is supplied by a pump, a compressor or an accumulator through a non-return valve. A pressure switch connected to the manifold (12) allows the pressure to be maintained at the desired value. It triggers an alarm in the event of an abnormal drop in pressure.

Lorsque les conteneurs sont sans pression le bâtiment repose par son embase (1) sur les plots (4) du socle (2). Lorsque la pression augmente les conteneurs se dilatent et viennent soulever l'embase (1). Le dispositif décrit permet de procéder au remplacement de conteneurs gonflables défectueux la maison restant en place.When the containers are without pressure, the building rests by its base (1) on the studs (4) of the base (2). When the pressure increases, the containers expand and lift the base (1). The device described makes it possible to replace defective inflatable containers, the house remaining in place.

Le tourillon (3) et l'alésage du plot (4) peuvent avoir des formes tronconiques la grande base étant en bas (figure 4), cette disposition permettant d'obtenir un effet d'enclavement entre l'embase et le socle. The pin (3) and the bore of the stud (4) may have frustoconical shapes, the large base being at the bottom (FIG. 4), this arrangement making it possible to obtain a wedging effect between the base and the base.
