Description

La présente invention a pour objet la construction de second oeuvre en zone sismique, et plus particulièrement de cloisons ou contrecloisons.The present invention relates to the construction of second work in seismic zone, and more particularly to partitions or contrecloisons.

Lors de la construction d'un bâtiment, on peut distinguer la structure porteuse et la structure non porteuse. Par définition, il est entendu que la structure porteuse s'appuie sur les fondations. La structure non porteuse est fixée à la structure porteuse par l'intermédiaire d'une ossature dite ossature primaire. Les structures non porteuses peuvent elles-même comprendre, lorsque nécessaire, une ossature que l'on nomme ossature secondaire, fixée à l'ossature primaire. La structure non porteuse comprend l'assemblage de divers éléments de l'ouvrage et en particulier l'assemblage de plaques de plâtre entre-elles dans le but de définir des volumes à l'intérieur du bâtiment. Cet assemblage de panneaux nécessite de fixer les panneaux sur l'ossature secondaire et primaire.When building a building, we can distinguish the supporting structure and the non-supporting structure. By definition, it is understood that the supporting structure is based on the foundations. The non-supporting structure is fixed to the supporting structure via a framework called primary framework. Non-bearing structures can themselves include, when necessary, a framework that is called secondary framework, attached to the primary framework. The non-load structure includes the assembly of various elements of the structure and in particular the assembly of plasterboard between them in order to define volumes inside the building. This assembly of panels requires fixing the panels on the secondary and primary framework.

Or, lors des séismes, il est vital que les bâtiments puissent résister aux sollicitations sismiques, et ainsi éviter l'éffondrement du bâtiment. De nombreuses solutions existent pour renforcer la structure porteuse, mais peu de solutions existent pour la structure non porteuse.However, during earthquakes, it is vital that buildings can withstand seismic stresses, and thus avoid collapse of the building. Many solutions exist to strengthen the carrier structure, but few solutions exist for the non-carrier structure.

Aussi il est devenu nécessaire de trouver un moyen pour éviter la chute des plaques de plâtre lors des tremblements de terre permettant ainsi d'éviter les dommages aux personnes et ainsi une évacuation facilitée.Also it became necessary to find a way to avoid falling plasterboard during earthquakes thus avoiding damage to people and thus facilitated evacuation.

Aussi le problème que se propose de résoudre l'invention est de fournir une cloison ou contrecloison parasismique résistante aux sollicitations sismiques.Also the problem to be solved by the invention is to provide a partition or contrecloison seismic resistant seismic forces.

De manière inattendue, les inventeurs ont mis en évidence qu'il est possible de désolidariser la cloison de la structure porteuse, en mettant en place des glissières sur les côtés verticaux et horizontaux de la cloison. Cela permet à la structure porteuse de bouger sans transmettre les mouvements et les contraintes à la cloison, et sans cisailler les fixations qui permettent de maintenir la cloison.Unexpectedly, the inventors have demonstrated that it is possible to separate the partition of the carrier structure, by setting up rails on the vertical and horizontal sides of the partition. This allows the supporting structure to move without transmitting the movements and constraints to the partition, and without shearing the fasteners that maintain the partition.

Dans ce but la présente invention se rapporte à une cloison parasismique présentant :

  • une ossature primaire comprenant d'une part un rail inférieur fixé dans un sol et un rail supérieur fixé dans un plafond, ces rails étant sensiblement horizontaux, et d'autre part deux autres rails sensiblement verticaux fixés sur des murs, ces rails présentant une section sensiblement en U ;
  • une ossature secondaire comprenant plusieurs montants sensiblement verticaux, ces montants présentant une section sensiblement en C, sur lesquel sont fixés un ou plusieurs panneaux;
    caractérisé en ce que les panneaux sont fixés aux montants de l'ossature secondaire
  • les montants présentant une section inférieure à la section des rails de l'ossature primaire;
  • les montants étant logés partiellement ou en totalité dans les rails de l'ossature primaire ; et
  • les montants pouvant se déplacer relativement par rapport aux rails de l'ossature primaire dans une direction verticale et horizontale.
For this purpose the present invention relates to a seismic partition having:
  • a primary framework comprising on the one hand a lower rail fixed in a floor and an upper rail fixed in a ceiling, these rails being substantially horizontal, and on the other hand two other substantially vertical rails fixed on walls, these rails having a section substantially U-shaped;
  • a secondary frame comprising a plurality of substantially vertical uprights, these uprights having a section substantially in C, on which are fixed one or more panels;
    characterized in that the panels are attached to the studs of the secondary framework
  • the posts having a section smaller than the section of the rails of the primary frame;
  • the amounts being housed partially or entirely in the rails of the primary frame; and
  • the posts being relatively movable relative to the rails of the primary framework in a vertical and horizontal direction.

Thus the seismic partition according to the invention does not collapse during an earthquake avoiding injury to the occupants of the structure.

Avantageusement, la cloison parasismique selon l'invention permet de maintenir disponible et libre les voies d'évacuation de l'ouvrage, sans les obstruer.Advantageously, the seismic partition according to the invention makes it possible to keep the escape routes of the structure available and free, without obstructing them.

Avantageusement, la cloison parasismique selon l'invention peut rester intacte lors de séismes de faible ou moyenne intensité, ce qui permet d'accélérer la remise en état du bâtiment et de réutiliser les bâtiments dans un délai réduit.Advantageously, the seismic partition according to the invention can remain intact during earthquakes of low or medium intensity, which makes it possible to accelerate the restoration of the building and to reuse buildings in a reduced time.

Avantageusement, la cloison parasismique selon l'invention peut être réalisée à moindre coût, en utilisant des rails et montants du commerce.Advantageously, the earthquake-proof partition according to the invention can be produced at a lower cost, by using rails and commercial uprights.

L'ossature primaire ou secondaire de la cloison parasismique selon l'invention peut être métallique ou en bois, ou en d'autres matériaux. De préférence, l'ossature est en métal.The primary or secondary frame of the earthquake-resistant partition according to the invention may be metallic or of wood, or of other materials. Preferably, the frame is metal.

La cloison parasismique selon l'invention comprend une ossature primaire métallique comprenant un rail supérieur fixé au plafond et un rail inférieur fixé dans le plancher. Ces deux rails sont disposés dans un même plan vertical. La cloison parasismique selon l'invention comprend également deux autres rails fixés sur des murs. Ces rails de l'ossature primaire peuvent être disposés dans le même plan vertical.The seismic partition according to the invention comprises a metal primary frame comprising an upper rail fixed to the ceiling and a lower rail fixed in the floor. These two rails are arranged in the same vertical plane. The seismic partition according to the invention also comprises two other rails fixed on walls. These rails of the primary frame can be arranged in the same vertical plane.

Les rails de la cloison parasismique selon l'invention présentent une section sensiblement en U. Il peut s'agir de rails disponible dans le commerce.The rails of the seismic partition according to the invention have a substantially U-shaped section. It may be commercially available rails.

De préférence les ailes des rails présentent une hauteur d'aile d'au moins 25 mm, de préférence au moins 40 mm.Preferably the wings of the rails have a wing height of at least 25 mm, preferably at least 40 mm.

En général, l'une des feuilles de papier utilisées pour fabriquer les plaques de plâtre est de couleur foncée, pouvant varier entre une couleur grise et une couleur marron, car elle est composée de fibres cellulosiques n'ayant pas subi un traitement de purification particulier. Classiquement, ce papier gris est obtenu à partir de pâte chimique non blanchie, et/ou de pâte mécanique, et/ou de pâte thermomécanique, et/ou de pâte mi-chimique. Par pâte mécanique, on entend générallement une pâte obtenue entièrement par des moyens mécaniques à partir de diverse matières premières, essentiellement du bois, pouvant être apportées par des produits de récupération issus du bois tels que les vieux cartons, des rognures de papier kraft et/ou de vieux journaux. Par pâte thermomécanique, on entend une pâte obtenue par traitement thermique suivi d'un traitement mécanique de la matière première. Par pâte mi-chimique, on entend une pâte obtenue en éliminant une partie des composants non cellulosiques contenus dans la matière première au moyen d'un traitement chimique, et nécessitant un traitement mécanique ultérieur pour disperser les fibres. L'autre feuille de papier utilisée pour fabriquer les plaques de plâtre présente une face visible appelée parement, de couleur généralement plus claire que la feuille grise.In general, one of the sheets of paper used to make the plasterboard is dark in color, which may vary between a gray color and a brown color, because it is composed of cellulosic fibers that have not undergone a particular purification treatment . Conventionally, this gray paper is obtained from unbleached chemical pulp, and / or mechanical pulp, and / or thermomechanical pulp, and / or semi-chemical pulp. By mechanical pulp is generally meant a paste obtained entirely by mechanical means from various raw materials, mainly wood, which can be provided by wood-based recovery products such as old cartons, kraft paper clippings and / or or old newspapers. By thermomechanical pulp is meant a paste obtained by heat treatment followed mechanical treatment of the raw material. By semi-chemical paste is meant a paste obtained by removing some of the non-cellulosic components contained in the raw material by means of a chemical treatment, and requiring subsequent mechanical treatment to disperse the fibers. The other sheet of paper used to make the plasterboard has a visible face called cladding, which is generally lighter in color than the gray sheet.
