Such a system comprises a load-bearing structure, composed of two series of structural profiles, respectively arranged in two intersecting directions in order to produce a planar grid, and slabs able to be housed and fixed in the spaces delimited by said grid. The supporting structure is fixed on the wall. The slabs cover said structure according to a paving thus providing a functional and / or decorative finish.
La fixation des dalles pourrait être envisagée directement sur les profilés de la structure porteuse. Cependant ces derniers assurent une reprise de planéité relativement à une paroi support et leur bon positionnement relativement à une dalle n'est pas toujours garanti. De plus, le matériau et les dimensions des profilés de structure peuvent laisser des déformations locales se produirent et l'interface présentée par les profilés de structure peut s'avérer ne plus permettre une fixation satisfaisante des dalles. Les dalles sont lourdes et particulièrement en utilisation murale il peut se produire des problèmes de torsion desdits profilés de structure, et particulièrement des traverses horizontales.  The fixing of the slabs could be considered directly on the profiles of the supporting structure. However, the latter ensure a recovery of flatness relative to a support wall and their good positioning relative to a slab is not always guaranteed. In addition, the material and the dimensions of the structural sections may allow local deformations to occur and the interface presented by the structural sections may no longer allow satisfactory fixing of the slabs. The slabs are heavy and particularly in wall use there may be problems of torsion of said structural sections, and particularly horizontal crosspieces.
La présente invention remédie à ces différents problèmes en proposant d'intercaler un profilé d'interface ou un croisillon d'interface entre la structure porteuse et les dalles .  The present invention overcomes these various problems by proposing to interpose an interface section or interface brace between the carrier structure and the slabs.
L'invention a pour objet un profilé d'interface pour un système d'habillage de paroi entre un profilé de structure présentant une extension selon une première direction (Dl) et une dalle comportant au moins un bord apte à venir se loger contre le profilé d'interface, caractérisé en ce que la section dudit profilé d'interface présente une forme intérieure complémentaire de la forme extérieure de la section dudit profilé de structure (21) transversalement à ladite première direction (Dl) et une ouverture selon une troisième direction (D3) perpendiculaire à la première direction (Dl) permettant l'introduction dudit profilé de structure dans le profilé d'interface selon ladite troisième direction (D3) de manière à pouvoir clipser le profilé d'interface sur le profilé de structure, le profilé d' interface coopérant avec la dalle de façon à ce que celle- ci soit maintenue par des verrous solidaires de cette dalle, verrous sélectivement escamotables et venant en appui sur le profilé d'interface. The invention relates to an interface section for a wall cladding system between a structural section having an extension in a first direction (D1) and a slab having at least one edge adapted to be housed against the profile interface, characterized in that the section of said interface section has an inner shape complementary to the outer shape of the section of said structural section (21) transversely to said first direction (D1) and an opening according to a third direction (D3) perpendicular to the first direction (D1) for introducing said structural section into the interface section in said third direction (D3) so as to be able to clip the interface section on the structural section, the interface section cooperating with the slab so that it is held by latches integral with this slab, selectively retractable latches and bearing on the interface section.
Avantageusement, le profilé d'interface présente une forme extérieure selon une deuxième direction sécante à la première direction et perpendiculaire à la troisième direction, complémentaire de la section du bord de la dalle transversalement à ladite première direction, afin de pouvoir fixer ladite dalle sur le profilé d'interface.  Advantageously, the interface section has an outer shape in a second secant direction in the first direction and perpendicular to the third direction, complementary to the slab edge section transversely to said first direction, in order to fix said slab on the interface profile.
Selon une autre caractéristique de l'invention, la forme extérieure de la section du profilé de structure comprend un quadrilatère présentant une largeur selon la deuxième direction et une épaisseur selon la troisième direction et où la section du profilé d'interface libère un espace interne apte à contenir ledit quadrilatère, ladite ouverture permettant un accès audit espace interne et présentant une largeur selon la deuxième direction légèrement inférieure à la largeur du quadrilatère.  According to another characteristic of the invention, the outer shape of the section of the structural section comprises a quadrilateral having a width in the second direction and a thickness in the third direction and wherein the section of the interface section releases a suitable internal space to contain said quadrilateral, said opening providing access to said inner space and having a width in the second direction slightly less than the width of the quadrilateral.
Selon une autre caractéristique de l'invention, la forme intérieure de la section du profilé d'interface comprend deux retours et au moins un fond, lesdits retours étant alignés, parallèles à la deuxième direction, disposés de part et d'autre de ladite ouverture, aptes à s'écarter afin d'élargir ladite ouverture jusqu'à atteindre une largeur au moins égale à la largeur du quadrilatère, afin de permettre l'entrée du quadrilatère dans ledit espace interne, et à se rapprocher afin de maintenir ledit quadrilatère, ledit au moins un fond étant distant selon la troisième direction desdits deux retours d'une grandeur sensiblement égale à l'épaisseur du quadrilatère afin d'immobiliser le quadrilatère selon la troisième direction.  According to another characteristic of the invention, the inner shape of the section of the interface section comprises two returns and at least one bottom, said returns being aligned, parallel to the second direction, disposed on either side of said opening , able to move apart in order to widen said opening until reaching a width at least equal to the width of the quadrilateral, so as to allow the entry of the quadrilateral into said internal space, and to get closer in order to maintain said quadrilateral, said at least one bottom being remote in the third direction of said two returns of a magnitude substantially equal to the thickness of the quadrilateral in order to immobilize the quadrilateral in the third direction.
Selon une autre caractéristique de l'invention, la forme intérieure de la section du profilé d'interface comprend encore au moins deux côtés distants selon la deuxième direction d'une grandeur sensiblement égale à la largeur du quadrilatère afin d'immobiliser le quadrilatère selon la deuxième direction. According to another characteristic of the invention, the shape The inside of the section of the interface section further comprises at least two distant sides in the second direction of a magnitude substantially equal to the width of the quadrilateral in order to immobilize the quadrilateral in the second direction.
Selon une autre caractéristique de l'invention, la section du bord de la dalle est sensiblement en forme d'un U avec une concavité tournée selon la deuxième direction et vers le profilé d'interface, les branches du U étant distantes selon la troisième direction d'une côte et où la forme extérieure de la section du profilé d'interface présente une saillie selon la deuxième direction présentant une côte selon la troisième direction sensiblement égale à la côte de la section de la dalle.  According to another characteristic of the invention, the section of the edge of the slab is substantially U-shaped with a concavity turned in the second direction and towards the interface section, the branches of the U being distant in the third direction a side and wherein the outer shape of the section of the interface section has a projection in the second direction having a coast in the third direction substantially equal to the side of the section of the slab.
Selon une autre caractéristique de l'invention, la forme extérieure de la section du profilé d'interface présente du côté opposé à l'ouverture, selon la troisième direction, un rentrant .  According to another characteristic of the invention, the outer shape of the section of the interface section has on the opposite side to the opening, in the third direction, a reentrant.
Selon une autre caractéristique de l'invention, la section du profilé d'interface présente une symétrie par rapport à la troisième direction.  According to another characteristic of the invention, the section of the interface section has a symmetry with respect to the third direction.
Selon une autre caractéristique de l'invention, au moins une surface s 'étendant selon la direction d'extension présente des jours.  According to another characteristic of the invention, at least one surface extending in the direction of extension has days.
Selon une autre caractéristique de l'invention, le profilé d'interface est réalisé en plastique auto extinguible .  According to another characteristic of the invention, the interface section is made of self-extinguishing plastic.
L'invention concerne encore un croisillon d'interface pour un système d'habillage de paroi comprenant une structure porteuse composée de deux séries de profilés de structure, respectivement disposés selon une première direction et une deuxième direction sécantes afin de s'entrecroiser pour réaliser un quadrillage selon un plan, et des dalles aptes à venir se loger dans les espaces délimités par ledit quadrillage, comprenant quatre portions de profilé d'interface selon l'un des modes de réalisation précédents, assemblées entre elles et disposées de telle manière à ce que leurs directions d'extension respectives forment une croix dont les branches sont alignées sur lesdites première et deuxième directions, et à ce que leur troisième direction soit perpendiculaire auxdites première et deuxième directions, leurs ouvertures étant disposées du même côté. The invention also relates to an interface brace for a wall cladding system comprising a support structure composed of two series of structural sections, respectively arranged in a first direction and a second secant direction in order to intersect to achieve a grid according to a plane, and slabs adapted to be housed in the spaces delimited by said grid, comprising four portions of interface section according to one of the preceding embodiments, assembled together and arranged in such a way that their respective directions of extension form a cross whose branches are aligned on said first and second directions, and that their third direction is perpendicular to said first and second directions, their openings being arranged on the same side.
Le profilé d'interface vient se clipser sur le profilé de structure et permet ainsi de présenter une jointure constante sur l'ensemble de la paroi. Les dalles viennent ensuite se fixer sur ledit profilé d'interface. Au contraire des profilés de structure qui présentent une répétitivité dimensionnelle variable et qui peuvent de plus se déformer, le profilé d'interface, avec une section peu déformable, garantit une interface constante et assure une fixation solide des dalles relativement à la structure porteuse.  The interface section is clipped on the structural section and thus provides a constant joint on the entire wall. The slabs then become attached to said interface section. In contrast to structural sections which have a variable dimensional repeatability and which can also deform, the interface section, with a low deformable section, ensures a constant interface and provides a solid attachment of the slabs relative to the carrier structure.
Le croisillon d'interface vient se clipser sur un croisement entre un profilé de structure porteur vertical et un profilé de structure traverse horizontal assurant ainsi une meilleure répartition des efforts en éliminant les problèmes de torsion desdites traverses.  The interface brace is clipped on a cross between a vertical structural support profile and a horizontal cross-section profile ensuring a better distribution of efforts by eliminating the torsional problems of said sleepers.
Un autre avantage du dispositif selon l'invention est, par introduction d'une pièce d'interface de séparer les deux interfaces et de rendre indépendante l'interface de fixation d'une dalle et l'interface de fixation d'un profilé de structure. Ainsi il est possible en modifiant le profilé d'interface de monter des dalles avec une interface quelconque sur des profilés de structure avec une interface quelconque. Le profilé d'interface permet ainsi de réaliser une adaptation entre deux standards d'interface.  Another advantage of the device according to the invention is, by introducing an interface piece to separate the two interfaces and to make independent the interface for fixing a slab and the interface for fixing a structural section. . Thus it is possible by modifying the interface section to mount slabs with any interface on structural sections with any interface. The interface section thus makes it possible to adapt between two interface standards.

Dans la description qui suit trois directions privilégiées vont être utilisées afin de décrire l'invention. L'invention concerne un profilé d'interface 1. Ce profilé d'interface 1 présente une extension importante selon une première direction notée Dl qui suit la génératrice dudit profilé 1. Cette direction coïncide encore avec la direction du profilé de structure 21 associé, sur lequel il vient s'assembler.  In the following description three preferred directions will be used to describe the invention. The invention relates to an interface section 1. This interface section 1 has a significant extension in a first direction denoted by Dl which follows the generatrix of said profile 1. This direction is still coincident with the direction of the associated structural section 21, on which he comes to assemble.
Le profilé d'interface 1 est analysé selon sa section réalisée selon une deuxième direction sécante D2, pouvant être perpendiculaire entre elles, mais pas nécessairement. Cette deuxième direction D2 coïncide aussi avec la deuxième direction d'un quadrillage de la structure porteuse 27 (voir fig. 9) du système d'habillage de paroi. Les première et deuxième directions Dl, D2 déterminent un plan P du quadrillage de la structure porteuse 27 et du mur et/ou plafond ainsi réalisé.  The interface section 1 is analyzed according to its section made in a second secant direction D2, which may be perpendicular to each other, but not necessarily. This second direction D2 also coincides with the second direction of a grid of the supporting structure 27 (see Fig. 9) of the wall cladding system. The first and second directions D1, D2 determine a plane P of the grid of the supporting structure 27 and the wall and / or ceiling thus produced.
Une troisième direction D3, est perpendiculaire aux deux premières directions Dl, D2 et donc au plan P.  A third direction D3 is perpendicular to the first two directions D1, D2 and thus to the plane P.
La figure 1 illustre en détail en vue en section selon la deuxième direction D2, une interface entre un profilé d'interface 1 et un profilé de structure 21 et entre un profilé d'interface 1 et une dalle 31. Le profilé d'interface 1 assure ainsi un double rôle d'interface. Tant le profilé d'interface 1, que le profilé de structure 21, que le bord de la dalle 31, ceux-ci présentent une extension selon la première direction Dl (non représentée sur cette figure) qui est ici perpendiculaire au plan de la figure. FIG. 1 illustrates in detail in sectional view along the second direction D2, an interface between an interface section 1 and a structural section 21 and between an interface section 1 and a slab 31. The interface section 1 thus ensures a dual role of interface. As the interface section 1, the structural section 21, the edge of the slab 31, they have an extension according to the first direction Dl (not shown in this figure) which is here perpendicular to the plane of the figure.
Le profilé de structure 21 comprend une partie 25 utilisée pour le fixer à la paroi 26. Ceci dégage ainsi une partie utile de section 22 dont la forme extérieure 23 permet un clipsage du profilé d'interface 1.  The structural section 21 comprises a part 25 used to fix it to the wall 26. This thus releases a useful part of section 22 whose outer shape 23 allows clipping of the interface section 1.
Pour cela, la section 2 du profilé d'interface 1 présente une forme intérieure 3 complémentaire de la forme extérieure 23 de la section 22 du profilé de structure 21.  For this, the section 2 of the interface section 1 has an inner shape 3 complementary to the outer shape 23 of the section 22 of the structural section 21.
De plus la section 2 du profilé d'interface 1 comporte une ouverture 6 selon la troisième direction D3. Cette ouverture 6 est telle qu'elle permette, le cas échéant en déformant la section 2 du profilé d'interface 1 l'introduction du profilé de structure 21 dans le profilé d'interface 1 selon la troisième direction D3. Ceci permet de clipser le profilé d'interface 1 sur le profilé de structure 21.  In addition, the section 2 of the interface section 1 has an opening 6 in the third direction D3. This opening 6 is such that it allows, if necessary by deforming the section 2 of the interface section 1 the introduction of the structural section 21 in the interface section 1 according to the third direction D3. This allows clipping of the interface section 1 on the structural section 21.
Après avoir été fixé par clipsage sur le profilé structure 21, le profilé d'interface 1 est utilisé selon la deuxième direction D2, afin de présenter une interface avec une dalle 31. Le profilé d'interface 1 présente alors une forme extérieure 4, selon la deuxième direction D2, complémentaire de la section 32 du bord rectiligne de la dalle 31. Ceci permet une fixation de ladite dalle 31 sur le profil d'interface 1. Ceci est par exemple rendu possible par une pièce de type verrou 36, sélectivement escamotable, par exemple par un déplacement selon la deuxième direction D2. Ainsi, le verrou 36 étant escamoté, la dalle 31 peut être mise en place par un déplacement selon la troisième direction D3, afin que la butée 34 de la dalle vienne en contact avec le profilé d'interface 1. La remise en place du verrou 36 assure ensuite un maintien en position de la dalle 31 relativement au profilé d'interface 1 dont la forme extérieure 4 est enveloppée par le profil correspondant de la section 32 de la dalle 1.  After being clipped onto the structural section 21, the interface section 1 is used in the second direction D2, in order to interface with a slab 31. The interface section 1 then has an outer shape 4, according to the second direction D2, complementary to the section 32 of the rectilinear edge of the slab 31. This allows a fixing of said slab 31 on the interface profile 1. This is for example made possible by a lock-type piece 36, selectively retractable for example by moving in the second direction D2. Thus, the latch 36 being retracted, the slab 31 can be put in place by a displacement in the third direction D3, so that the stop 34 of the slab comes into contact with the interface section 1. The replacement of the lock 36 then maintains the position of the slab 31 relative to the interface section 1 whose outer shape 4 is enveloped by the corresponding profile of the section 32 of the slab 1.
Le profilé de structure 21 est typiquement réalisé en acier galvanisé. Selon un mode de réalisation, détaillé à la figure 2, la forme extérieure 23 de la section 22 du profilé de structure 21 comprend dans sa partie utile destinée à venir en interface avec le profilé d'interface 1, un quadrilatère 24 présentant une largeur 1 selon la deuxième direction D2 et une épaisseur e selon la troisième direction D3. Ceci correspond par exemple à un profilé de structure 21 en forme de T, très répandu, la barre horizontale du T formant ledit quadrilatère 24, tandis que la barre verticale 25 du T est utilisée comme entretoise et comme moyen de fixation du profilé de structure 21 avec la paroi 26, mur ou plafond. The structural section 21 is typically made of galvanized steel. According to one embodiment, detailed in FIG. 2, the outer shape 23 of the section 22 of the profile of structure 21 comprises in its useful part intended to come into interface with the interface section 1, a quadrilateral 24 having a width 1 in the second direction D2 and a thickness e in the third direction D3. This corresponds, for example, to a widely used T-shaped structural section 21, the horizontal bar of the T forming said quadrilateral 24, whereas the vertical bar 25 of the T is used as a spacer and as a means for fixing the structural section 21 with wall 26, wall or ceiling.
Dans ce cas, la section 2 du profilé d'interface 1 est telle qu'elle comporte un espace interne 5 vide, apte à contenir ledit quadrilatère 24.  In this case, the section 2 of the interface section 1 is such that it comprises an empty internal space 5 capable of containing said quadrilateral 24.
Les figures 3-6 présentent différents exemples de section de profilé d'interface 1 dont la forme intérieure 3 et la forme extérieure 4 changent, tout en répondant à la condition précédente .  Figures 3-6 show different examples of interface section section 1 whose inner shape 3 and outer shape 4 change, while meeting the previous condition.
Dans toutes ces figures 3-6, le profilé d'interface 1 est creux et ménage un espace au moins égal à l'espace vide 5, figuré en pointillé, correspondant au quadrilatère 24 du profilé de structure 21.  In all these figures 3-6, the interface section 1 is hollow and provides a space at least equal to the empty space 5, represented in dotted line, corresponding to the quadrilateral 24 of the structural section 21.
De même l'ouverture 6, précédemment évoquée, permet l'accès audit espace interne 5. La mise en place du profilé d'interface 1 sur le profilé de structure s'effectue par un déplacement relatif suivant la troisième direction D3. L'ouverture 6 est par conséquent pratiquée selon cette troisième direction D3. Elle présente selon la deuxième direction D2 une largeur 1-, en correspondance avec la dimension du quadrilatère 24 selon cette seconde direction D2, soit la largeur 1.  Similarly, the opening 6, previously mentioned, allows access to said internal space 5. The establishment of the interface section 1 on the structural section is effected by a relative movement along the third direction D3. The opening 6 is therefore made in this third direction D3. According to the second direction D2, it has a width 1, corresponding to the dimension of the quadrilateral 24 in this second direction D2, ie the width 1.
Avantageusement, une possible déformation élastique du profilé d'interface 1 est mise à profit. La largeur 1- de l'ouverture 6 est dimensionnée inférieure à la largeur 1 du quadrilatère 24. Ainsi une fois le profilé de structure 21 installé dans le profilé d'interface 1, il est retenu par l'exiguïté de ladite ouverture 6. L'introduction du profilé de structure 21 est cependant possible en déformant le profilé d'interface 1 pour permettre d'élargir l'ouverture 6 jusqu'à une largeur égale à la largeur 1 du quadrilatère 24.Advantageously, a possible elastic deformation of the interface section 1 is used. The width 1 of the opening 6 is dimensioned smaller than the width 1 of the quadrilateral 24. Thus once the structural section 21 installed in the interface section 1, it is retained by the smallness of said opening 6. L introduction of the structural section 21 is however possible by deforming the interface section 1 to widen the opening 6 to a width equal to the width 1 of the quadrilateral 24.
Ladite déformation peut avantageusement être provoquée par l'introduction du profilé de structure 21 dans l'ouverture 6 lors du montage/clipsage . Ladite introduction et la déformation qui en résulte peuvent avantageusement être facilitées par des formes complémentaires du profilé de structure 21 et des lèvres de l'ouverture 6 formant un biseau et/ou un chanfrein. L'élasticité du profilé d'interface 1 assure avantageusement un retour à une position de repos identique à la position initiale et garantissant le clipsage, après introduction du profilé de structure 21. Said deformation may advantageously be caused by the introduction of the structural section 21 into the opening 6 during assembly / clipping. Said introduction and the resulting deformation can advantageously be facilitated by complementary shapes of the structural section 21 and the lips of the opening 6 forming a bevel and / or a chamfer. The elasticity of the interface section 1 advantageously provides a return to a rest position identical to the initial position and ensuring the clipping, after introduction of the structural section 21.
Selon un mode de réalisation particulier, la forme intérieure 3 de la section 2 du profilé d'interface 1 comprend deux retours 7, 8 et au moins un fond 9. Lesdits retours 7, 8 sont alignés, parallèles à la deuxième direction D2, et disposés de part et d'autre de l'ouverture 6. Lesdits retours 7, 8 sont aptes à s'écarter afin d'élargir l'ouverture 6 jusqu'à atteindre une largeur au moins égale à la largeur 1 du quadrilatère 24, au moins durant l'introduction du quadrilatère 24 dans l'espace interne 5. Les retours 7, 8, au repos, se rapprochent afin de réduire la largeur de l'ouverture 6 à une valeur 1- inférieure à 1. La longueur cumulée des deux retours 7, 8 est ainsi égale à la différence des deux largeurs 1 et 1-. Les retours assurent un maintien du quadrilatère 24 dans l'espace interne 5.  According to a particular embodiment, the inner shape 3 of the section 2 of the interface section 1 comprises two returns 7, 8 and at least one bottom 9. Said returns 7, 8 are aligned, parallel to the second direction D2, and disposed on either side of the opening 6. Said returns 7, 8 are able to deviate to widen the opening 6 to reach a width at least equal to the width 1 of the quadrilateral 24, the minus during the introduction of the quadrilateral 24 into the inner space 5. The returns 7, 8, at rest, come closer to reduce the width of the opening 6 to a value 1- less than 1. The cumulative length of the two returns 7, 8 is thus equal to the difference of the two widths 1 and 1. The returns maintain the quadrilateral 24 in the inner space 5.
Afin de compléter ce maintien, la forme interne 3 comprend encore au moins un fond 9 tel qu'il vienne en contact avec le quadrilatère 24 sur son côté opposé au côté venant en contact avec les retours 7, 8. Ledit au moins un fond 9 peut prendre des formes très diverses, telles qu'illustrées aux figures 3-6.  In order to complete this maintenance, the internal shape 3 also comprises at least one bottom 9 such that it comes into contact with the quadrilateral 24 on its side opposite the side coming into contact with the returns 7, 8. Said at least one bottom 9 can take a variety of shapes, as illustrated in Figures 3-6.
Une caractéristique est cependant que la distance e' entre les retours 7, 8 et le ou les fonds 9, mesurée en projection sur la troisième direction D3, soit sensiblement égale à l'épaisseur e du quadrilatère 24. Le terme "sensiblement" indique ici une certaine tolérance. Cette tolérance prend en compte un nécessaire jeu de montage, ainsi qu'une possible déformation relative des deux profilés 1 et 21. La distance (e') peut être légèrement supérieure à (e) .A characteristic is however that the distance e 'between the returns 7, 8 and the fund or funds 9, measured in projection on the third direction D3, is substantially equal to the thickness e of the quadrilateral 24. The term "substantially" indicates here some tolerance. This tolerance takes into account a necessary set of mounting, as well as a possible relative deformation of the two sections 1 and 21. The distance (e ') may be slightly greater than (e).
L'action conjointe et contradictoire des retours 7, 8 et du ou des fonds 9 assure une immobilisation du quadrilatère 24 selon la troisième direction D3, dans l'espace 5. The joint and contradictory action of the returns 7, 8 and the fund 9 ensures immobilization of the quadrilateral 24 in the third direction D3, in space 5.
De manière similaire selon la deuxième direction D2, la forme intérieure 3 de la section 2 du profilé d'interface 1 comprend des moyens d'immobiliser le quadrilatère 24 selon cette deuxième direction D2. Ceci peut être réalisé par au moins deux côtés 10, 11 dont la distance (Ι') mesurée en projection sur la deuxième direction D2 est sensiblement égale à la largeur 1 du quadrilatère 24. Le terme "sensiblement" indique ici aussi une certaine tolérance. Cette tolérance prend en compte un nécessaire jeu de montage, ainsi qu'une possible déformation relative des deux profilés 1, 21. La distance (1') peut être légèrement supérieure à (1). L'action conjointe et contradictoire des côtés 10, 11 assure une immobilisation du quadrilatère 24 selon la deuxième direction D2, dans l'espace 5.  Similarly in the second direction D2, the inner shape 3 of the section 2 of the interface section 1 comprises means for immobilizing the quadrilateral 24 in this second direction D2. This can be achieved by at least two sides 10, 11 whose distance (Ι ') measured in projection on the second direction D2 is substantially equal to the width 1 of the quadrilateral 24. The term "substantially" here also indicates a certain tolerance. This tolerance takes into account a necessary mounting clearance, as well as a possible relative deformation of the two sections 1, 21. The distance (1 ') may be slightly greater than (1). The joint and contradictory action of the sides 10, 11 ensures immobilization of the quadrilateral 24 in the second direction D2, in the space 5.
La forme interne 3 de la section 2 du profilé d'interface 1 telle que décrite dans ses différents modes de réalisation permet un assemblage par clipsage du profilé d'interface 1 sur le profilé de structure 21. Cet assemblage réalisé, le profilé d'interface 1 présente maintenant au moins une forme externe 4 de sa section 2, latéralement selon la deuxième direction D2, vers le bord d'une dalle 31 adjacente. Cette forme externe 4 présente une complémentarité avec la forme de la section 32 de la dalle 31 en regard et permet avantageusement une fixation de ladite dalle 31 sur le profilé d'interface 1.  The internal shape 3 of the section 2 of the interface section 1 as described in its various embodiments allows a clipping assembly of the interface section 1 on the structural section 21. This assembly made, the interface section 1 now has at least one external shape 4 of its section 2, laterally along the second direction D2, to the edge of an adjacent slab 31. This external form 4 has a complementarity with the shape of the section 32 of the slab 31 opposite and advantageously allows a fixing of said slab 31 on the interface section 1.
Ainsi, selon un mode de réalisation avantageux, la section 32 du bord de la dalle 31 (fig. 1) est sensiblement en forme d'un U en creux. La concavité 33 du U est orientée selon la deuxième direction D2, le creux 33 faisant face au profilé d'interface 1 en regard. Ledit U est figuré sur les figures 3-6 par un contour en pointillé de la section 32.  Thus, according to an advantageous embodiment, the section 32 of the edge of the slab 31 (FIG 1) is substantially in the form of a hollow U. The concavity 33 of the U is oriented in the second direction D2, the recess 33 facing the interface section 1 opposite. Said U is shown in Figures 3-6 by a dashed outline of section 32.
Les branches 34, 35 du U sont par exemple respectivement formées par une butée 34 et par un verrou 36 (fig. 1) . Ces branches se caractérisent par un écartement de cote E mesurée selon la troisième direction D3. The branches 34, 35 of the U are for example respectively formed by a stop 34 and a lock 36 (FIG 1). These branches are characterized by an E measured gauge distance according to the third direction D3.
La forme extérieure 4 de la section 2 du profilé d'interface 1 présente alors avantageusement une saillie 12 complémentaire, présentant une cote E' sensiblement égale à la côte E de la section 32 de la dalle 31. Le terme The outer shape 4 of the section 2 of the interface section 1 then advantageously has a complementary projection 12, having a dimension E 'substantially equal to the E-side of the section 32 of the slab 31. The term
"sensiblement" indique ici aussi une certaine tolérance."substantially" here also indicates a certain tolerance.
Cette tolérance prend en compte un nécessaire jeu de montage, ainsi qu'une possible déformation relative des deux profilésThis tolerance takes into account a necessary set of mounting, as well as a possible relative deformation of the two sections
1, 21. E1 peut être légèrement inférieure à E. L'insertion au moins partielle de la saillie 12 dans le creux 33 du U de la dalle 31 assure l'immobilisation de la dalle 31 relativement au profilé d'interface 1. 1, 21. E 1 may be slightly less than E. The at least partial insertion of the projection 12 in the recess 33 of the U of the slab 31 ensures the immobilization of the slab 31 relative to the interface section 1.
Le calage d'une dalle 31 selon la deuxième direction D2 est assuré par au moins un autre profilé de structure 21, muni d'un profilé d'interface clipsé 1, disposés latéralement à la dalle 31 du côté opposé au présent profilé d'interface The wedging of a slab 31 in the second direction D2 is provided by at least one other structural section 21, provided with a clipped interface section 1, arranged laterally to the slab 31 on the opposite side to this interface section.
1. 1.
Différentes formes extérieures 4 sont possibles qui assurent cette condition, comme illustrées aux figures 3-6.  Different outer shapes 4 are possible which provide this condition, as illustrated in Figures 3-6.
Selon une autre caractéristique avantageuse, la forme extérieure 4 de la section 2 du profilé d'interface 1 présente un rentrant 13. Ce rentrant 13 est avantageusement disposé dans la section 2 du profilé d'interface 1 du côté opposé à l'ouverture 6 et s'étend selon la troisième direction D3. Ce rentrant 13, par exemple illustré aux figures 3 et 6 et sous une autre forme avec deux rentrants à la figure 4, présente de nombreux avantages. La forme de ce rentrant 13 diminue la résistance à la flexion autour de la première direction Dl et facilite ainsi la déformation décrite précédemment qui permet d'augmenter la largeur 1- de l'ouverture 6 et d'autoriser le clipsage. Au contraire, la forme de ce rentrant 13 augmente la rigidité en flexion autour de la deuxième direction D2, renforçant ainsi le profilé d'interface 1. De plus, de manière avantageuse ce rentrant 13 peut, vers l'intérieur de la section 2, former le ou les fonds 9.  According to another advantageous characteristic, the outer shape 4 of the section 2 of the interface section 1 has a reentrant 13. This reentrant 13 is advantageously arranged in the section 2 of the interface section 1 on the opposite side to the opening 6 and extends in the third direction D3. This reentrant 13, for example illustrated in Figures 3 and 6 and in another form with two reentrants in Figure 4, has many advantages. The shape of this reentrant 13 decreases the resistance to bending around the first direction Dl and thus facilitates the deformation described above which increases the width 1 of the opening 6 and allow clipping. On the contrary, the shape of this reentrant 13 increases the bending stiffness around the second direction D2, thus reinforcing the interface section 1. In addition, advantageously this reentrant 13 can, towards the inside of the section 2, form the fund (s) 9.
De plus, comme illustré aux figures 7 et 8 , ce rentrant 13 peut être utile pour accueillir des retours jointifs 37, 37' de deux dalles 31 afin d'assurer une finition esthétique. Les deux dalles 31, 31' sont disposées latéralement de part et d'autre d'un profilé d'interface 1. Les butées 34, 34' viennent s'appuyer contre la face opposée à l'ouverture 6, dans laquelle est réalisée le rentrant 13. Les bords des dalles sont prolongés, au niveau des butées 34, 34' par les retours 37, 37'. Ces retours 37, 37' viennent avantageusement se loger, côte à côte, dans le rentrant 13, réalisant ainsi une finition esthétique du raccord entre deux dalles 31, 31'. Moreover, as illustrated in FIGS. 7 and 8, this reentrant 13 may be useful for accommodating joined returns 37, 37 'of two slabs 31 to ensure an aesthetic finish. The two slabs 31, 31 'are arranged laterally on either side of an interface section 1. The abutments 34, 34' come to bear against the face opposite the opening 6, in which the 13. The edges of the slabs are extended at the abutments 34, 34 'by the returns 37, 37'. These returns 37, 37 'are advantageously housed, side by side, in the reentrant 13, thus achieving an aesthetic finish of the connection between two slabs 31, 31'.
Selon un mode de réalisation avantageux, le profilé de structure 21 est lui-même symétrique, afin de pouvoir comme montré à la figure 7 accueillir deux dalles voisines sur un même profilé d'interface 1. La section 2 du profilé d'interface 1 présente une symétrie par rapport à la troisième direction D3. Ceci est encore illustré par les exemples des figures 3-6.  According to an advantageous embodiment, the structural section 21 is itself symmetrical, in order to be able, as shown in FIG. 7, to accommodate two adjacent slabs on the same interface section 1. The section 2 of the interface section 1 presents a symmetry with respect to the third direction D3. This is further illustrated by the examples of Figures 3-6.
Le profilé d'interface 1 est réalisé selon une certaine longueur selon la première direction Dl . Cette longueur est au minimum suffisante pour accommoder la largeur d'un verrou 36. Les verrous 36 sont disposés à des emplacements répartis sur une dalle et en nombre limité.  The interface section 1 is formed along a certain length in the first direction D1. This length is at least sufficient to accommodate the width of a lock 36. The locks 36 are arranged at locations distributed over a slab and in limited numbers.
Toute surface présentant une extension selon la première direction Dl peut être ajourée. Un tel retrait de matière favorise la flexion du profilé d'interface 1 autour de la première direction Dl et facilite ainsi la déformation décrite précédemment qui permet d'augmenter la largeur 1- de l'ouverture 6 et rend possible le clipsage. De plus ce retrait de matière limite la quantité de matière utilisée et par là la masse du profilé d'interface 1. Un exemple d'un tel ajourage est visible à la figure 12 présentant une utilisation d'un profilé d'interface 1 dans un croisillon 50 en perspective.  Any surface having an extension in the first direction D1 may be perforated. Such a removal of material promotes the bending of the interface section 1 around the first direction D1 and thus facilitates the deformation described above which increases the width 1 of the opening 6 and makes possible the clipping. In addition, this removal of material limits the quantity of material used and hence the mass of the interface profile 1. An example of such an openwork is visible in FIG. 12, showing the use of an interface profile 1 in a cross 50 in perspective.
En complément du clipsage, lorsque des efforts très importants sont envisagés, par exemple en montage plafond ou en présence de dalles très lourdes, l'assemblage du profilé d'interface 1 sur le procédé de structure 21 peut être renforcé par un vissage, un collage, un rivetage ou tout autre moyen d'assemblage similaire. Ceci s'applique aussi au croisillon d'interface 50 issu dudit profilé d'interface 1.In addition to the clipping, when very large efforts are envisaged, for example in ceiling mounting or in the presence of very heavy slabs, the assembly of the interface section 1 on the structural process 21 can be reinforced by screwing, gluing. , riveting or any other similar means of assembly. This also applies to interface brace 50 from said interface section 1.
Le profilé d'interface 1 tel que décrit précédemment est avantageusement réalisé en matériau plastique. Ce matériau plastique est avantageusement un plastique auto extinguible du fait d'une utilisation en bâtiment, afin de répondre aux normes. Un tel matériau plastique utilisé pour le profilé d'interface 1, ou le croisillon d'interface 50 qui est décrit plus loin, permet d'obtenir l'élasticité nécessaire à la déformation permettant le clipsage. Il permet encore d'obtenir la rigidité nécessaire à l'application envisagée en maintenant un poids faible du profilé d'interface 1 ou du croisillon d'interface 50. Une réalisation moulée simple à mettre en œuvre est ainsi possible pour le profilé d'interface 1 comme pour le croisillon d'interface 50. The interface section 1 as described above is advantageously made of plastic material. This plastic material is advantageously a self-extinguishing plastic due to use in buildings, to meet standards. Such a plastic material used for the interface section 1, or the interface brace 50 which is described below, makes it possible to obtain the elasticity necessary for the deformation allowing clipping. It also makes it possible to obtain the rigidity necessary for the application envisaged by maintaining a low weight of the interface section 1 or the interface crosspiece 50. A molded embodiment that is easy to implement is thus possible for the interface section. 1 as for the interface brace 50.
Le profilé d'interface 1 ainsi réalisé, de par sa forme de section 2 et sa matière, garantit une interface (côte E) reproductible et invariante vis-à-vis de l'interface avec une dalle 31 et garantit ainsi un assemblage efficace des dalles 31.  The interface section 1 thus produced, by its sectional shape 2 and its material, guarantees an interface (E-side) that is reproducible and invariant with respect to the interface with a slab 31 and thus guarantees an efficient assembly of slabs 31.
En se référant aux figures 9-12, le système d'habillage de paroi 26, mur et/ou plafond va maintenant être décrit, dans lequel le profilé d'interface 1 précédemment décrit est destiné à être employé.  Referring to Figs. 9-12, the wall cladding system 26, wall and / or ceiling will now be described, wherein the previously described interface section 1 is intended to be used.
Comme illustré à la figure 9, ce système comprend une structure porteuse 27, composée de deux séries 28, 29 de profilés de structure 21, respectivement disposés selon deux directions sécantes Dl, D2 afin de s'entrecroiser pour réaliser un quadrillage sensiblement plan, selon un plan P.  As illustrated in FIG. 9, this system comprises a carrier structure 27, composed of two series 28, 29 of structural sections 21, respectively arranged in two intersecting directions D1, D2 in order to intersect each other in order to produce a substantially plane grid, according to a plan P.
Un exemple d'une telle structure porteuse 27 est illustré à la figure 9. Une telle structure porteuse 27 est typiquement construite en fixant une première série 28 de profilés de structure 31 selon une première direction Dl, constituant des porteurs parcourant typiquement toute la longueur de la paroi 26, régulièrement espacés d'une distance correspondant à une première dimension des dalles 31. Une deuxième série 29 de profilés de structure 31 est ensuite mise en place selon la deuxième direction D2, sécante, pouvant être perpendiculaire à la première direction Dl. Ces profilés de structures 31 sont sous forme de traverses de longueur adaptée à l'espacement de la première série 28. Ces traverses viennent se fixer aux profilés de structure 21 de la première série 28 et le cas échéant à la paroi 26. Ces traverses sont régulièrement espacées d'une distance correspondant à une deuxième dimension des dalles 31. Les deux séries 28, 29 de profilés de structure 21 sont disposées de manière à réaliser un quadrillage sensiblement plan et régulier. Ledit quadrillage délimite des espaces libres 30 entre les profilés de structure 21. An example of such a carrier structure 27 is illustrated in FIG. 9. Such a carrier structure 27 is typically constructed by fixing a first series 28 of structural sections 31 in a first direction D1, constituting carriers typically traversing the entire length of the structure. the wall 26, regularly spaced a distance corresponding to a first dimension of the slabs 31. A second series 29 of structural sections 31 is then implemented in the second direction D2 secant, which may be perpendicular to the first direction Dl. These structural sections 31 are in the form of crosspieces of length adapted to the spacing of the first series 28. These crosspieces are fixed to the structural sections 21 of the first series 28 and, where appropriate, to the wall 26. These crosspieces are regularly spaced apart by a distance corresponding to a second dimension of the slabs 31. The two series 28, 29 of structural sections 21 are arranged so as to achieve a substantially flat and regular grid. Said grid delimits free spaces 30 between the structural sections 21.
Le système comprend encore des dalles 31 aptes à venir se loger dans les espaces libres 30 délimités par ledit quadrillage 27.  The system also comprises slabs 31 adapted to be housed in the free spaces 30 delimited by said grid 27.
Ainsi, la figure 10 présente un détail de ladite structure porteuse 27, où est figuré un profilé de structure 21 de la première série 28 selon la première direction Dl, et un profilé de structure 21 de la deuxième série 29 selon la deuxième direction D2. Un espace libre 30 apparaît ainsi apte à accueillir une dalle 31. Ladite dalle 31 peut être mise en place dans ledit espace libre 30 par un déplacement selon une troisième direction D3 perpendiculaire au plan P défini par Dl, D2. Ledit déplacement est effectué ici de bas en haut, relativement à la figure, afin d'amener la dalle 31 en position. La fixation de la dalle 31 en position est assurée par les verrous 36 avantageusement montés sur des bords opposés de la dalle 31 et face à face, deux à deux.  Thus, Figure 10 shows a detail of said support structure 27, which is shown a structural section 21 of the first series 28 in the first direction Dl, and a structural section 21 of the second series 29 in the second direction D2. A free space 30 thus appears able to accommodate a slab 31. Said slab 31 can be placed in said free space 30 by a displacement in a third direction D3 perpendicular to the plane P defined by D1, D2. Said displacement is carried out from bottom to top, relative to the figure, in order to bring the slab 31 into position. Fixing the slab 31 in position is provided by the locks 36 advantageously mounted on opposite edges of the slab 31 and face to face, two by two.
Comme illustré sur cette figure 10, au minimum quatre verrous 36 peuvent être disposés afin de réaliser une fixation de la dalle 31 (seuls trois verrous sont visibles) . II pourrait être envisagé d'augmenter ce nombre à six ou huit verrous en ajoutant des verrous sur les mêmes bords déjà employés ou sur les deux autres bords de la dalle 31, actuellement libres.  As illustrated in this FIG. 10, at least four locks 36 may be arranged in order to fix the slab 31 (only three locks are visible). It could be envisaged to increase this number to six or eight locks by adding locks on the same edges already used or on the other two edges of the slab 31, currently free.
Comme vu précédemment, l'interface offerte par le profilé de structure 21 peut ne pas être satisfaisante pour permettre une interface directe assurant une fixation correcte de la dalle 31.  As seen previously, the interface offered by the structural section 21 may not be satisfactory to allow a direct interface ensuring correct fixing of the slab 31.
En référence à la figure 11 et selon l'invention, il est ajouté par clipsage sur les profilés de structure 21, des segments de profilé d'interface 1. Le clipsage des profilés d'interface 1 s'effectue selon la troisième direction D3, de bas en haut dans la figure représentée. Il est avantageusement mis en place autant de profilés d'interface 1 que de verrous 36, chaque profilé d'interface 1 étant disposé sur le profilé de structure 21 de manière à se trouver en regard d'un verrou 36, lorsque la dalle 31 est en position. With reference to FIG. 11 and according to the invention, it is added by clipping on the structural sections 21, segments of interface section 1. The clipping of the interface sections 1 is made in the third direction D3, from bottom to top in the figure shown. It is advantageously put in place as many interface sections 1 as locks 36, each interface section 1 being disposed on the structural section 21 so as to be opposite a lock 36, when the slab 31 is in position.
La figure 11 présente un exemple de dalle 31 comprenant quatre verrous 36 et pour laquelle sont mis en place quatre profilés d'interface 1.  FIG. 11 shows an example of slab 31 comprising four locks 36 and for which four interface profiles 1 are put in place.
Les dimensions indicatives de la section 2 du profilé d'interface 1 sont 1 = 24 mm, pour accepter un profilé de structure 21 en forme de T dont la barre/quadrilatère 24 présente une largeur 1 = 24 mm. La hauteur du profilé est dimensionnée pour une cote E = 10 mm.  The indicative dimensions of the section 2 of the interface section 1 are 1 = 24 mm, to accept a T-shaped structural section 21 whose bar / quadrilateral 24 has a width 1 = 24 mm. The height of the profile is dimensioned for a dimension E = 10 mm.
Afin d'améliorer encore le principe de l'invention, il est réalisé un croisillon d'interface 50 tel qu'illustré par les figures 3 et 12. Ce croisillon d'interface 50 comprend quatre portions la, lb, le, ld de profilé d'interface 1 selon l'un quelconque des modes de réalisation précédemment décrits .  In order to further improve the principle of the invention, an interface brace 50 is made as illustrated by FIGS. 3 and 12. This interface brace 50 comprises four portions 1a, 1b, 1d, 1d of profile interface 1 according to any one of the previously described embodiments.
Ces quatre portions la-ld sont assemblées entre elles et disposées de manière à ce que leurs directions d'extension Da-Dd respectives forment une croix. Les branches de ladite croix sont telles qu'elles puissent être alignées sur lesdites première et deuxième directions Dl, D2 respectives des deux séries 28, 29 de profilé de structure 21 de la structure porteuse 27 de la figure 9. Chacune desdites quatre portions la-ld est encore orientée autour de sa génératrice Da-Dd respective de manière à ce que sa troisième direction D3 soit perpendiculaire auxdites première et deuxième directions Dl, D2, et que leurs ouvertures 6 respectives soit toutes disposées du même côté.  These four portions la-ld are assembled together and arranged so that their respective extension directions Da-Dd form a cross. The branches of said cross are such that they can be aligned with said respective first and second directions D1, D2 of the two series 28, 29 of structural section 21 of the supporting structure 27 of FIG. 9. Each of said four portions la- ld is further oriented around its respective generator Da-Dd so that its third direction D3 is perpendicular to said first and second directions D1, D2, and that their respective openings 6 are all arranged on the same side.
Le croisillon d'interface 50 ainsi réalisé peut être assemblé par clipsage sur la structure porteuse en enveloppant la forme extérieure 23 du profilé de structure 21 au niveau d'un croisement entre les deux séries 28, 29 de la structure porteuse 27. The interface brace 50 thus produced can be assembled by clipping onto the carrier structure by wrapping the outer shape 23 of the structural section 21 at a cross between the two series 28, 29 of the supporting structure 27.
La figure 14 illustre ainsi le montage. Un croisillon d'interface 50 est disposé par clipsage sur chaque croisement de la structure porteuse 27 selon la troisième direction D3. Ensuite une dalle 31 peut être mise en place dans chaque espace libre 30, les verrous 36 venant s ' interfacer chacun avec une portion de profilé d'interface la-ld constituant ledit croisillon d'interface 50.  Figure 14 thus illustrates the assembly. An interface brace 50 is clipped onto each cross of the carrier structure 27 along the third direction D3. Then a slab 31 can be put into place in each free space 30, the latches 36 coming to each interface with a portion of the interface section la-ld constituting said interface brace 50.
Un croisillon d'interface 50 présente tous les avantages des profilés d'interface 1. De plus l'utilisation de croisillons d'interface 50 plutôt que de segments de profilés d'interface 1 présente plusieurs avantages.  An interface brace 50 has all the advantages of the interface sections 1. In addition, the use of interface braces 50 rather than interface section segments 1 has several advantages.
Un premier avantage est que le positionnement d'un croisillon ne pose aucune difficulté : il est positionné sur un croisement, c'est-à-dire sur quatre branches de la structure porteuse. De par les dimensions du croisillon 50, la portion de profilé d'interface la-ld constituant une branche est automatiquement placée en bonne position et un verrou 36 se retrouve obligatoirement en regard d'un profilé d'interface 1.  A first advantage is that the positioning of a cross poses no problem: it is positioned on a cross, that is to say on four branches of the carrier structure. Due to the dimensions of the spider 50, the portion of the interface section la-ld constituting a branch is automatically placed in a good position and a latch 36 is necessarily found facing an interface section 1.
Un second avantage est que s'il est possible qu'un profilé d'interface 1 glisse le long d'un profilé de structure 21 ; la forme en croix du croisillon 50 clipsé sur deux profilés de structure 21 de directions différentes empêche tout glissement et assure ainsi un maintien en place des profilés d'interface 1 qui restent en regard des positions des verrous 36.  A second advantage is that if it is possible that an interface section 1 slides along a structural section 21; the cross shape of the crosspiece 50 clipped on two structural sections 21 of different directions prevents slipping and thus ensures a retention in place of the interface sections 1 which remain opposite the positions of the locks 36.
Un autre avantage encore du croisillon d'interface 50 est de multiplier les zones d'interface possibles avec chaque verrou 36. Ainsi la mise en place de quatre croisillons d'interface 50 aux quatre croisements entourant un espace 30 présente huit zones d'interface aptes à accueillir un verrou 36. Ainsi avantageusement une dalle 31 comportant quatre verrous 36, lorsqu'elle est carrée, peut avantageusement et indifféremment être mise en place selon une orientation autour de la troisième direction D3 ou selon toute autre orientation modulo 90° de la précédente. Ceci simplifie le montage des dalles 31. Un autre avantage du croisillon est qu'il vient renforcer la résistance de la structure porteuse au niveau des croisements entre porteur 28 et traverse 29. Ces croisements présentent une fragilité, notamment dans le cas d'utilisation murale où les dalles 31 peuvent être très lourdes et où des déformations des traverses horizontales peuvent être observées. L'utilisation de croisillon d'interface 50 permet en renforçant la structure porteuse 27, au niveau des croisements, d'employer des profilés de structure 21 identiques en application plafond et en application murale. Yet another advantage of the interface brace 50 is to multiply the possible interface areas with each latch 36. Thus, the introduction of four interface braces 50 at the four crossings surrounding a space 30 has eight suitable interface areas. to accommodate a latch 36. Thus advantageously a slab 31 having four latches 36, when square, can advantageously and indifferently be implemented in an orientation around the third direction D3 or in any other orientation modulo 90 ° of the previous . This simplifies the mounting of slabs 31. Another advantage of the cross is that it reinforces the strength of the carrier structure at the cross between carrier 28 and crosses 29. These crosses have a fragility, especially in the case of wall use where the slabs 31 can be very heavy and where deformations of the horizontal crosspieces can be observed. The use of interface brace 50 makes it possible, by reinforcing the support structure 27, at the crossings, to use identical structural sections 21 in ceiling application and in wall application.
Comme le profilé d'interface 1, le croisillon d'interface 50 est avantageusement réalisé en matière plastique, tel du plastique auto extinguible. Le croisillon d'interface 50 est avantageusement réalisé monobloc par moulage.  Like the interface section 1, the interface crosspiece 50 is advantageously made of plastic, such as self-extinguishing plastic. The interface brace 50 is advantageously made in one piece by molding.
Les dimensions indicatives d'un croisillon d'interface 50 sont indiquées à la figure 13 présentant un plan côté en deux vues : face et gauche.  The indicative dimensions of an interface brace 50 are shown in Figure 13 having a side plane in two views: face and left.
