- Panels of insulating material or plaster, not shown, are arranged and fixed on the primary beams, in a known manner.
- the primary beam 1 comprises a core 3 in this case vertical, and a lower sole 5 and an upper flange 4, the two flanges 4 and 5 being in this case horizontal.

- the spacer 2 is moved parallel to itself, vertically, downwards, until its sole 6 bears against the upper face of the sole 5 of the primary.
- the spacer is moved in the plane of its sole 6, so that the material bridge 15A passes into the slot 14 of the sole 6.
- the leg 15 is then at or just above the full part (excluding light 12) of the sole 6.
- the tab 15 passes over and / or shaves the central rib 6C, by slight elastic deformation.
- the tab 15 is then advantageously between the two central ribs 6B and 6C.
- the lateral ribs 6A and 6D allow the positioning of the screws for fixing drywall, not shown. Note that, given the perspective, the lateral rib 6A is not visible on the Figures 3 to 5 .
- the spacer 2 is then secured to the primary 1, and blocked without degree of freedom.
- the plane of the flange 15 is located above the plane of the sole 6 of the spacer 2 at a distance equal to, or slightly less than, the thickness of the soleplate.
- the central ribs 6B and 6C are advantageously separated by a distance slightly greater than the width of the tab 15, in the longitudinal direction of the sole 5.
- the tab 15 is locked in translation between said central ribs 6B and 6C, since it is at level of the upper face of the sole and any translation will cause its abutment on the rib.
- connection / joining One can possibly refine the connection / joining by exerting pressure on the tab 15 to the sole 6 of the primary to press it on the latter.
- connection / securing is removable. It suffices to make the spacer follow the opposite path to that described above.

Description
La présente invention concerne deux profilés pourvus de moyens de liaison réciproque amovible, permettant d'assurer leur liaison ou assemblage de manière amovible, les deux profilés étant destinés à être disposés de manière croisée et notamment à angle droit, et étant sensiblement dans un même plan.The present invention relates to two profiles provided with means of removable mutual connection, to ensure their connection or assembly removably, the two sections being intended to be arranged in a cross-way and in particular at right angles, and being substantially in the same plane .
L'invention concerne également un premier profilé pourvu d'un moyen de liaison amovible à un second profilé.The invention also relates to a first section provided with a removable connection means to a second profile.
L'invention est destinée à réaliser des structures porteuses, du type faux plafond, comprenant des séries de profilés, métalliques, généralement en acier galvanisé ou en aluminium extrudé, et présentant des sections droites de formes variées ; en C, en Oméga, en I, en L, etc. Ces profilés sont disposés parallèles et à angle droit, pour former un maillage, et sur lequel sont fixées des plaques de plâtre, pour former un faux plafond.The invention is intended to produce supporting structures, of the false ceiling type, comprising series of profiles, metal, usually galvanized steel or extruded aluminum, and having cross sections of various shapes; in C, Omega, I, L, etc. These profiles are arranged parallel and at right angles, to form a mesh, and on which are fixed plasterboard, to form a false ceiling.
De manière connue, les structures pour faux plafond comportent :
- a) une série de profilés de section droite en C, couramment « entretoises », disposés parallèlement les uns aux autres avec un intervalle de l'ordre de 60 cm.
- b) une série de profilés dits « primaires », disposés parallèlement les uns aux autres, avec un intervalle de l'ordre de 120 cm.
- a) a series of sections of straight section C, commonly "spacers", arranged parallel to each other with an interval of the order of 60 cm.
- b) a series of profiles called "primary", arranged parallel to each other, with an interval of about 120 cm.
Les primaires comportent une âme, et une semelle perpendiculaire.The primaries have a soul, and a perpendicular sole.
Les primaires présentent une rigidité et une résistance à la flexion bien supérieures à celles des entretoises.The primers have much higher stiffness and flexural strength than the spacers.
On connaît par la demande de brevet
Ces moyens connus de liaison comportent :
- au moins une languette ou une patte prévue sur la semelle du primaire, et faisant saillie par rapport au plan de la semelle ;
- une lumière prévue sur un des flancs latéraux verticaux de l'entretoise.
- at least one tongue or tab provided on the sole of the primary, and protruding from the plane of the sole;
- a light provided on one of the vertical lateral flanks of the spacer.
Cependant, ce système connu ne donne pas entièrement satisfaction car il nécessite :
- une butée sur le primaire pour bloquer l'entretoise dans une direction perpendiculaire à la semelle du primaire ;
- la mise en place de l'entretoise sur la semelle selon deux mouvements successifs, à savoir poser l'entretoise sur la semelle, puis déplacer celle-ci latéralement pour faire pénétrer la languette (prévue sur la semelle du primaire) dans la lumière prévue sur l'entretoise ;
- de bloquer l'entretoise en rabattant la languette de la semelle.
- a stop on the primary to block the spacer in a direction perpendicular to the sole of the primary;
- placing the spacer on the sole in two successive movements, namely to put the spacer on the sole, then move it laterally to penetrate the tongue (provided on the sole of the primary) in the light provided on the spacer;
- to block the spacer by folding the tongue of the sole.
De plus, ce système connu n'assure pas une liaison entièrement fiable entre l'entretoise et le primaire.In addition, this known system does not ensure a completely reliable connection between the spacer and the primary.
Enfin, la présence d'un bord franc, donc coupant, sur les côtés de l'entretoise peut entraîner des blessures.Finally, the presence of a sharp edge, so sharp, on the sides of the spacer can cause injury.
La présente invention vise à remédier à ces inconvénients et propose un ensemble pour plafond suspendu comprenant une entretoise et un primaire, pourvus de moyens de liaison amovible réciproque, permettant de réaliser l'assemblage entre l'entretoise et le primaire de manière rapide et fiable, et sans risque de blessures.The present invention aims to remedy these drawbacks and proposes a suspended ceiling assembly comprising a spacer and a primer, provided with reciprocal removable connection means, allowing to assemble quickly between the spacer and the primary, without risk of injury.
À cette fin, selon invention, l'ensemble pour plafond suspendu, comprenant d'une part une poutre primaire et d'autre part une entretoise à section transversale en C, la poutre et l'entretoise étant destinées à être solidarisées perpendiculairement l'une à l'autre, la poutre primaire comprenant une âme, et au moins une semelle transversale à cette dernière, et au moins un élément mâle en saillie par rapport au plan de la semelle, tel qu'une patte ou languette, rattaché à la semelle du primaire par un pont de matière, ladite entretoise comportant :
- une semelle plane ;
- deux rebords ou flancs latéraux sensiblement orthogonaux à la semelle,
- au moins une lumière apte à coopérer avec ledit élément mâle prévu sur ledit primaire,
- une découpe à contour fermé, de forme polygonale ou circulaire ou elliptique, apte à être traversée par ledit élément mâle, et
- au moins une fente débouchant dans la découpe,
- a flat sole;
- two flanges or lateral flanks substantially orthogonal to the sole,
- at least one light adapted to cooperate with said male element provided on said primary,
- a contour with closed contour, of polygonal or circular or elliptical shape, able to be traversed by said male element, and
- at least one slot opening into the cutout,
Ainsi, la coopération entre la lumière et l'élément mâle est améliorée et permet une liaison fiable de l'entretoise sur le primaire, et une manipulation sécurisée de l'entretoise.Thus, the cooperation between the light and the male element is improved and allows a reliable connection of the spacer on the primary, and a safe manipulation of the spacer.
Selon une forme préférée, la lumière sur l'entretoise présente une forme et une surface telles que l'élément mâle puisse passer au travers de la lumière, lors d'un déplacement de l'entretoise dans une direction transversale à la semelle du primaire.According to a preferred form, the light on the spacer has a shape and a surface such that the male element can pass through the light, during a displacement of the spacer in a direction transverse to the sole of the primary.
De préférence, la lumière comporte :
- une découpe à contour fermée, de forme polygonale ou circulaire ou elliptique, et
- au moins une fente débouchant dans la découpe.
- a closed contour cut, of polygonal or circular or elliptical shape, and
- at least one slot opening into the cutout.
Plus précisément, la fente présente une direction perpendiculaire à la direction longitudinale de l'entretoise.More specifically, the slot has a direction perpendicular to the longitudinal direction of the spacer.
La fente est tangente au bord de la découpe opposé à l'extrémité libre de l'entretoise.The slot is tangent to the edge of the cutout opposite the free end of the spacer.
La découpe et la fente dessinent, dans le plan de la semelle de l'entretoise, une lettre P en majuscule, la jambe du P formant ladite fente.The cut and the slot draw, in the plane of the sole of the spacer, a capital letter P, the leg of the P forming said slot.
Plus précisément, le P est orienté de manière que la barre verticale de la lettre P soit perpendiculaire à la direction longitudinale de l'entretoise.Specifically, the P is oriented so that the vertical bar of the letter P is perpendicular to the longitudinal direction of the spacer.
La semelle de l'entretoise comporte au moins une nervure longitudinale faisant saillie par rapport au plan de la semelle.The sole of the spacer has at least one longitudinal rib projecting from the plane of the sole.
L'invention porte également sur une poutre primaire pour une structure telle qu'un faux plafond suspendu, du type comprenant une âme, et au moins une semelle transversale à cette dernière, et au moins un élément mâle en saillie par rapport au plan de la semelle, tel qu'une patte ou languette, rattaché à la semelle du primaire par un pont de matière, le primaire étant destiné à être solidarisé à un profilé formant une entretoise, perpendiculaire au primaire.The invention also relates to a primary beam for a structure such as a suspended suspended ceiling, of the type comprising a core, and at least one sole transverse thereto, and at least one male element projecting from the plane of the sole, such as a tab or tab, attached to the sole of the primary by a bridge of material, the primary being intended to be secured to a profile forming a spacer, perpendicular to the primary.
La patte ou languette présente une forme de surface complémentaire à la découpe prévue sur l'entretoise, et de surface légèrement inférieure par rapport à la découpe.The tab or tab has a surface shape complementary to the cutout provided on the spacer, and slightly smaller surface area relative to the cut.
Par ailleurs, l'invention concerne un ensemble comprenant d'une part un profilé primaire et d'autre part une entretoise, tels que ci-dessus.Furthermore, the invention relates to an assembly comprising on the one hand a primary profile and on the other hand a spacer, such as above.
Enfin, La présente invention concerne une structure telle qu'un plafond suspendu, comprenant au moins un ensemble tel que ci-dessus.Finally, the present invention relates to a structure such as a suspended ceiling, comprising at least one assembly as above.

Dans un second temps, l'entretoise 2 est déplacée parallèlement à elle-même, verticalement, vers le bas, jusqu'à ce que sa semelle 6 porte contre la face supérieure de la semelle 5 du primaire.In a second step, the
On aboutit à la position de la
- le retour 5A de la semelle 5 a pénétré dans la fente transversale 11, ce qui permet à la semelle 6 de l'entretoise de reposer sur la face supérieure de la semelle 5 ;
- la patte 15 de la semelle 5 a traversé la découpe 13 de l'entretoise et se trouve donc au niveau sensiblement du plan de la face supérieure de la semelle 6.
- the
return 5A of the sole 5 has penetrated into thetransverse slot 11, which allows the sole 6 of the spacer to rest on the upper face of the sole 5; - the
tab 15 of the sole 5 has passed through thecutout 13 of the spacer and is therefore substantially level with the plane of the upper face of the sole 6.
Dans un temps ultérieur, on déplace l'entretoise dans le plan de sa semelle 6, de manière que le pont de matière 15A passe dans la fente 14 de la semelle 6. La patte 15 est alors au niveau ou juste au-dessus de la partie pleine (hors lumière 12) de la semelle 6. La patte 15 passe au-dessus et/ou rase la nervure centrale 6C, par légère déformation élastique.In a subsequent time, the spacer is moved in the plane of its sole 6, so that the
La patte 15 se trouve alors avantageusement entre les deux nervures centrales 6B et 6C.The

Les nervures centrales 6B et 6C sont avantageusement séparées d'une distance légèrement supérieure à la largeur de la patte 15, dans la direction longitudinale de la semelle 5. La patte 15 est bloquée en translation entre lesdites nervures centrales 6B et 6C, car elle est au niveau de la face supérieure de la semelle et toute translation provoquera sa butée sur la nervure.The
On peut éventuellement affiner la liaison / solidarisation en exerçant une pression sur la patte 15 vers la semelle 6 du primaire pour la plaquer sur cette dernière.One can possibly refine the connection / joining by exerting pressure on the
La liaison / solidarisation est amovible. Il suffit de faire faire à l'entretoise le cheminement inverse de celui décrit ci-dessus.The connection / securing is removable. It suffices to make the spacer follow the opposite path to that described above.
