Description

Domaine technique et état de l'artTechnical field and state of the art

L'invention concerne un système de fixation d'un panneau sur un bord d'un élément de structure porteuse, élément tel qu'une poutre ou une dalle.The invention relates to a system for attaching a panel to an edge of a supporting structure element, such as a beam or a slab.

Il est connu de réaliser des bâtiments comprenant une structure intérieure porteuse, en béton, en acier ou en bois, et des panneaux fermant les espaces libres extérieurs entre les éléments de la structure. Les panneaux ont par exemple une hauteur sensiblement égale à une hauteur d'un étage de bâtiment, et sont fixés rigidement par exemple en bas sur le bord d'une dalle de sol et en haut sur le bord d'une dalle de plafond.It is known to produce buildings comprising a load-bearing internal structure, made of concrete, steel or wood, and panels closing the external free spaces between the elements of the structure. The panels have for example a height substantially equal to a height of a building floor, and are fixed rigidly for example down on the edge of a floor slab and at the top on the edge of a ceiling slab.

Des systèmes de fixation rapides ont été développés pour faciliter la fixation du panneau sur la structure. Ces systèmes sont généralement à base de pièces plates métalliques pliées de manière appropriée et qui sont vissées d'une part sur le panneau et d'autre part sur l'élément de structure. La publication FR 2 940 376 qui traite du même domaine, décrit ainsi un dispositif pour l'assemblage entre elles de deux parois d'un bâtiment, quelle que soit leur inclinaison respective, ledit dispositif comprenant l'ensemble des caractéristiques du préambule de la revendication 1. Ce dispositif met en oeuvre un dispositif de serrage axial destiné à coopérer avec un boîtier tubulaire préalablement fixé dans une cavité que comporte l'une des parois à assembler et avec un berceau en « U » préalablement fixé sur l'autre des parois à assembler.Quick fastening systems have been developed to facilitate attachment of the panel to the structure. These systems are generally based on metal pieces folded appropriately and which are screwed on the one hand on the panel and on the other hand on the structural element. The publication FR 2 940 376 which deals with the same field, thus describes a device for the assembly together of two walls of a building, whatever their respective inclination, said device comprising all of the features of the preamble of claim 1. This device implements an axial clamping device for cooperating with a tubular housing previously fixed in a cavity that comprises one of the walls to be assembled and with a cradle "U" previously fixed on the other of the walls to be assembled.

On constate dans la pratique qu'un élément de structure, poutre ou dalle par exemple, peut se déformer en fonction de la charge d'exploitation appliquée sur le dit élément. Par exemple, la mise en place d'un carrelage ou de meubles sur une dalle béton peut entraîner une flexion verticale de la dalle, flexion qui peut atteindre 1 à 1,5 cm en bordure de dalle pour une dalle en béton. Cette flexion de la dalle va engendrer des désordres et / ou transmettre des contraintes mécaniques sur les panneaux des étages inférieurs ou supérieurs, rigidement fixés aux bords des dalles, au risque d'endommager un ou des panneaux.It is found in practice that a structural element, beam or slab for example, can be deformed according to the operating load applied to said element. For example, placing tiling or furniture on a concrete slab can lead to vertical bending of the slab, which can reach 1 to 1.5 cm at the edge of the slab for a concrete slab. This bending of the slab will cause disorders and / or transmit mechanical stresses on the panels of the lower or upper floors, rigidly attached to the edges of the slabs, the risk of damaging a panel or panels.

Egalement, un séisme de type tremblement de terre peut entraîner un déplacement horizontal important d'une dalle par rapport à l'autre. Si un panneau est fixé rigidement à une dalle et à l'autre, le déplacement d'une dalle par rapport à l'autre va entraîner également au mieux une déformation du panneau, au pire un décrochement d'un panneau. Les normes antisismiques européennes actuelles prévoient qu'un bâtiment doit pouvoir résister, sans que ses éléments principaux se détachent, à un déplacement d'une dalle par rapport à l'autre de l'ordre de 4,5 cm.Also, an earthquake-type earthquake can cause a large horizontal displacement of one slab relative to the other. If a panel is fixed rigidly to one slab and to the other, the displacement of one slab relative to the other will also lead to a better deformation of the panel, at worst a detachment of a panel. The current European anti-seismic standards stipulate that a building must be able to withstand, without its main elements being detached, a displacement of one slab relative to the other of the order of 4.5 cm.

Les systèmes de fixation de panneaux connus à ce jour ne permettent pas de tenir cette contrainte.Panel fastening systems known to date do not allow to hold this constraint.

On constate également dans le domaine du bâtiment qu'il est souvent difficile d'obtenir des éléments de structures tels que des poutres ou des dalles présentant des bords parfaitement rectilignes sur de grandes longueurs. Ceci est particulièrement vrai pour des éléments de structure en béton. Ainsi, il est courant de voir dans le gros oeuvre béton des tolérances de l'ordre de 1 à 3 cm par rapport à une droite parfaite. Les panneaux étant eux parfaitement plats, il est souvent difficile de fixer correctement un panneau sur un bord de dalle avec les systèmes de fixation rigideIt is also found in the building sector that it is often difficult to obtain structural elements such as beams or slabs having perfectly straight edges over long lengths. This is especially true for concrete structural elements. Thus, it is common to see in the concrete shell tolerances of the order of 1 to 3 cm compared to a perfect line. The panels being perfectly flat, it is often difficult to properly fix a panel on a slab edge with rigid fastening systems

Description de l'inventionDescription of the invention

L'invention propose un nouveau système de fixation, ne présentant pas tout ou partie des inconvénients des systèmes de fixation rigide connus.The invention proposes a new fastening system, not having all or part of the disadvantages of known rigid fastening systems.

Plus précisément l'invention propose un nouveau système de fixation de panneau sur un bord d'un élément d'une structure porteuse, élément tel qu'une poutre ou une dalle, système comprenant :

  • un étrier comprenant un sabot, le sabot présentant une section transversale en U et présentant une première paroi latérale reliée par un pontet à une deuxième paroi latérale ; le pontet présente une lumière s'étendant selon une direction longitudinale du pontet parallèle à la première paroi latérale, et
  • une pièce de liaison , comprenant une pièce plate et un goujon de forme sensiblement cylindrique s'étendant selon un axe du goujon perpendiculaire à un plan principal de la pièce plate ; le dit goujon comprend une première extrémité fixée à une face de dessous de la pièce plate, le dit goujon comprend également une tête fixée à une deuxième extrémité du goujon ; la dite tête du goujon a une section par exemple rectangulaire, ovale ou oblongue dans un plan perpendiculaire à l'axe du goujon ; une petite dimension de la section de la tête est inférieure à une largeur de la lumière de l'étrier et une grande dimension de la section de la tête est supérieure à la largeur de la lumière de l'étrier.
More specifically, the invention proposes a new system for fastening a panel to an edge of an element of a supporting structure, such as a beam or a slab, comprising:
  • a stirrup comprising a shoe, the shoe having a U-shaped cross section and having a first side wall connected by a bridge to a second side wall; the bridge has a light extending in a longitudinal direction of the bridge parallel to the first side wall, and
  • a connecting piece, comprising a flat piece and a substantially cylindrical stud extending along an axis of the stud perpendicular to a main plane of the flat piece; said stud comprises a first end attached to a bottom face of the flat piece, said stud also comprises a head attached to a second end of the stud; said head of the stud has a section for example rectangular, oval or oblong in a plane perpendicular to the axis of the stud; a small dimension of the section of the head is less than a width of the light of the stirrup and a large dimension of the section of the head is greater than the width of the light of the stirrup.

La pièce de liaison est destinée à être solidarisée à l'élément de structure, dalle ou poutre par exemple, et l'étrier est destiné à être solidarisé au dessus du panneau à fixer. Comme on le verra mieux plus loin dans des exemples, la pièce de liaison est fixée à l'étrier par l'intermédiaire de son goujon. Mais la pièce de liaison n'est pas fixée rigidement à l'étrier car le goujon peut coulisser dans la lumière, selon la direction longitudinale du pontet et selon l'axe du goujon. Le pied du panneau étant fixé rigidement, une fixation non rigide en haut du panneau permet de ne pas déformer ou rompre le panneau et / ou la pièce de liaison en cas de mouvement de la dalle selon la direction longitudinale du pontet, par exemple en cas de séisme, ou en cas de mouvement de la dalle selon l'axe du goujon, par exemple en cas de variation de la charge de la dalle.The connecting piece is intended to be secured to the structural element, slab or beam for example, and the stirrup is intended to be secured above the panel to be fixed. As will be seen better later in examples, the connecting piece is attached to the stirrup via its stud. But the connecting piece is not fixed rigidly to the stirrup because the stud can slide in the light in the longitudinal direction of the bridge and along the axis of the stud. The foot of the panel being rigidly fixed, a non-rigid attachment at the top of the panel makes it possible not to deform or break the panel and / or the connecting piece in case of movement of the slab in the longitudinal direction of the bridge, for example in case earthquake, or in case of movement of the slab along the axis of the stud, for example in case of variation of the load of the slab.

Le système de fixation selon l'invention permet ainsi notamment de rapporter des panneaux en façade sur la structure principale porteuse en bois, en béton ou en acier d'un bâtiment. Le système de fixation assure le réglage des panneaux dans les trois dimensions, pour compenser les défauts ou tolérances dimensionnelles de la structure principale porteuse. Le système de fixation permet également d'absorber les variations dimensionnelles de la structure principales porteuse sans engendrer d'effort mécanique et de déformation dommageable sur les panneaux des étages inférieurs ou supérieurs.The fastening system according to the invention thus makes it possible in particular to bring back facade panels on the main supporting structure made of wood, concrete or steel of a building. The fastening system adjusts the panels in three dimensions to compensate for defects or dimensional tolerances of the main carrier structure. The fastening system also makes it possible to absorb the dimensional variations of the main carrier structure without generating mechanical stress and damaging deformation on the panels of the lower or upper stages.

La pièce de liaison peut également comprendre une ailette plane fixée sur la pièce plate, s'étendant depuis une face de dessus de la pièce plate dans un plan qui est perpendiculaire au plan principal de la pièce plate ; la dite ailette comprend au moins un trou de fixation. L'ailette permet le positionnement et la fixation d'un deuxième panneau au dessus d'un premier panneau maintenu par la pièce plate.The connecting piece may also include a planar wing attached to the flat piece, extending from a top face of the flat piece in a plane that is perpendicular to the main plane of the flat piece; said fin comprises at least one fixing hole. The fin allows the positioning and fixing of a second panel above a first panel held by the flat part.

Le système selon l'invention peut encore comprendre une équerre de positionnement comprenant une première paroi et une deuxième paroi perpendiculaire à la première paroi. La première paroi de l'équerre est destinée à venir en appui sur une face de dessus de l'élément de structure et sur la face de dessous de la pièce plate, et une paroi latérale de l'étrier étant destinée à venir en appui sur la deuxième paroi de l'équerre. L'équerre permet de rattraper les défauts de réalisation de la dalle ou de la poutre ; elle permet d'avoir des surfaces d'appui parfaitement planes pour la pièce plate et pour le panneau.The system according to the invention may further comprise a positioning bracket comprising a first wall and a second wall perpendicular to the first wall. The first wall of the bracket is intended to bear on a top face of the structural element and on the underside of the flat part, and a side wall the stirrup being intended to bear against the second wall of the square. The square makes it possible to make up for the defects of realization of the slab or the beam; it allows for perfectly flat bearing surfaces for the flat part and the panel.

Description d'un mode de réalisation de l'inventionDescription of an embodiment of the invention

Le système de fixation a été développé pour les panneaux objets du brevet FR2922565 , constitués d'un empilage de plis croisés à 90°, chaque pli étant constitué de lames de bois et de bandes de remplissage (isolant, pare-feu, etc.) positionnées entre les lames de bois. Les figures en annexe montrent ainsi l'utilisation du système de fixation sur de tels panneaux.The fastening system has been developed for patented panels FR2922565 , consisting of a stack of folds crossed at 90 °, each fold consisting of wooden strips and filling strips (insulation, firewall, etc.) positioned between the wooden boards. The figures in the appendix thus show the use of the fastening system on such panels.

Mais le système de fixation selon l'invention peut être utilisé plus généralement pour fixer tout type de panneau, par exemple des panneaux pleins réalisés en un unique matériau.But the fastening system according to the invention can be used more generally to fix any type of panel, for example solid panels made of a single material.

Comme dit précédemment, le système de fixation selon l'invention permet de fixer un panneau à un bord d'un élément d'une structure porteuse, par exemple une dalle 100. Le système de fixation comprend principalement deux éléments : un étrier 200 et une pièce de liaison 300.As mentioned above, the fastening system according to the invention makes it possible to fix a panel to an edge of an element of a supporting structure, for example a slab 100. The fixing system mainly comprises two elements: a stirrup 200 and a connecting piece 300.

L'étrier 200 comprend (figure 1) un sabot présentant une section en U. Une première paroi latérale 210 est reliée par un pontet 220 à une deuxième paroi latérale 230. Le pontet présente une lumière 240 s'étendant selon une direction longitudinale du pontet parallèle à la première paroi latérale 210. L'étrier est adapté à être positionné au dessus d'un panneau (figures 5 à 9).The caliper 200 includes ( figure 1 ) a shoe having a U-shaped section. A first side wall 210 is connected by a bridge 220 to a second side wall 230. The bridge has a light 240 extending in a direction longitudinally of the bridge parallel to the first side wall 210. The stirrup is adapted to be positioned above a panel ( Figures 5 to 9 ).

Dans l'exemple représenté, la lumière est de forme oblongue. La première paroi 210 de l'étrier est pleine, plane, sensiblement rectangulaire. La deuxième paroi de l'étrier comprend deux ailes, pleines, planes, dans le même plan sensiblement rectangulaires et espacées l'une de l'autre. La première paroi 210 comprend au moins un trou de fixation. De la même façon, chaque aile de la deuxième paroi comprend au moins un trou de fixation. Les trous de fixation permettent de solidariser les parois 210, 220 aux faces principales du panneau à l'aide d'un organe de fixation tel qu'une vis ou un clou, une tige filetée ou une broche, sans avoir recours à un outil pour percer les parois de l'étrier.In the example shown, the light is oblong. The first wall 210 of the stirrup is solid, flat, substantially rectangular. The second wall of the stirrup comprises two wings, solid, flat, in the same substantially rectangular plane and spaced apart from each other. The first wall 210 comprises at least one fixing hole. In the same way, each wing of the second wall comprises at least one fixing hole. The fixing holes make it possible to secure the walls 210, 220 to the main faces of the panel by means of a fastener such as a screw or a nail, a threaded rod or a spindle, without having recourse to a tool for pierce the walls of the stirrup.

Ce mode de réalisation de l'étrier est spécifique au panneau représenté sur les figures. Il permet que les parois latérales de l'étrier viennent en appui sur des lames de bois du panneau (c'est-à-dire sur la partie structurante du panneau), sur des lames qui ont des directions différentes, et ceci sans avoir besoin de découper (et donc de fragiliser) une lame. D'autres modes de réalisation de l'étrier sont envisageables, notamment avec deux parois latérales identiques, au choix des parois pleines, sensiblement rectangulaires, ou des parois présentant deux ailes.This embodiment of the stirrup is specific to the panel shown in the figures. It allows the side walls of the stirrup come to bear on wooden boards of the panel (that is to say on the structuring part of the panel), on blades that have different directions, and this without needing to cut (and thus weaken) a blade. Other embodiments of the stirrup are possible, in particular with two identical side walls, the choice of solid walls, substantially rectangular, or walls with two wings.

Dans l'exemple représenté, l'étrier est réalisé dans une pièce plate de métal pliée d'épaisseur environ 2 à 4 mm. La première paroi 210 mesure environ 70 à 130 mm par 70 à 110 mm, chaque aile de la deuxième paroi 230 mesure environ 20 à 40 mm par 70 à 110 mm, le pontet mesure environ 100 à 150 mm par 130 à 190 mm. Ces valeurs donnent un ordre de grandeur des dimensions des pièces d'un système selon l'invention, bien sûr à titre purement indicatif. Ces valeurs dépendent en pratique notamment de l'épaisseur du panneau, de son mode de réalisation, de la tenue mécanique recherchée, etc.In the example shown, the stirrup is made in a flat piece of folded metal about 2 to 4 mm thick. The first wall 210 measures about 70 to 130 mm by 70 to 110 mm, each wing of the second wall 230 measures about 20 to 40 mm by 70 to 110 mm, the bridge measures about 100 to 150 mm by 130 to 190 mm. These values give an order of magnitude of the dimensions of the parts of a system according to the invention, of course for purely indicative purposes. These values depend in practice in particular on the thickness of the panel, its embodiment, the desired mechanical strength, etc.

L'étrier 200 comprend également une pièce de renfort 250 comprenant une lumière de forme et de dimensions similaires à celles du pontet ; la dite pièce de renfort est fixée, par exemple soudée, sous le pontet de sorte que la lumière du pontet et la lumière de la pièce de renfort correspondent. La pièce de renfort 250 améliore la résistance mécanique à l'arrachement du pontet.The stirrup 200 also comprises a reinforcement piece 250 comprising a light of shape and dimensions similar to those of the bridge; said reinforcing piece is fixed, for example welded, under the bridge so that the light of the bridge and the light of the reinforcement piece correspond. The reinforcing member 250 improves the mechanical resistance to tearing of the bridge.

La pièce de liaison 300 comprend une pièce plate 305 et un goujon 310 de forme sensiblement cylindrique ; le goujon 310 s'étend à une première extrémité de la pièce plate 305, selon un axe du goujon perpendiculaire à un plan principal de la pièce plate ; le dit goujon 310 comprend une première extrémité 320 fixée à une face de dessous de la pièce plate ; le dit goujon 310 comprend également une tête 330 fixée à une deuxième extrémité du goujon. La tête du goujon a, dans un plan perpendiculaire à l'axe du goujon, une section dont une petite dimension est inférieure à une largeur de la lumière 240 de l'étrier 200 et dont une grande dimension est supérieure à la largeur de la lumière 240 de l'étrier 200. Ces dimensions sont importantes car elles permettent le verrouillage de la pièce de liaison sur l'étrier, comme on le verra mieux plus loin.The connecting piece 300 comprises a flat piece 305 and a stud 310 of substantially cylindrical shape; the stud 310 extends at a first end of the flat piece 305, along an axis of the stud perpendicular to a main plane of the flat piece; said stud 310 comprises a first end 320 fixed to a bottom face of the flat piece; said stud 310 also includes a head 330 attached to a second end of the stud. The head of the stud has, in a plane perpendicular to the axis of the stud, a section of which a small dimension is less than a width of the light 240 of the stirrup 200 and of which a large dimension is greater than the width of the light 240 of the caliper 200. These dimensions are important because they allow the locking of the connecting piece on the caliper, as will be seen better below.

Dans l'exemple représenté, la section de la tête du goujon a une forme rectangulaire ; dans une variante, la dite section a une forme ovale ou oblongue. La pièce plate de la pièce de liaison est réalisée en métal ; elle mesure environ 130 à 190 mm par 300 à 400 mm, et a une épaisseur d'environ 6 à 10 mm. Le goujon a une longueur d'environ 40 à 80 mm et un diamètre d'environ 14 à 19 mm. Les dimensions de la pièce plate et du goujon sont choisies en fonction des dimensions du panneau à fixer, de la dalle et de la résistance mécanique recherchée. Le diamètre du goujon est choisi égal ou légèrement inférieur à la largeur de la lumière 240. Ainsi, lorsque le goujon est positionné dans la lumière, le panneau est immobilisé dans un plan horizontal. La longueur du goujon est choisie pour permettre d'une part de rattraper les défauts d'épaisseur et / ou de positionnement de la dalle, qui sont couramment de l'ordre de quelques millimètres à 2 à 4 cm, sans endommager le panneau dont la dimension est parfaitement maîtrisée d'un panneau à l'autre, et d'autre part d'absorber un éventuel fléchissement de la dalle dû à une variation de charge de la dalle, fléchissement qui peut atteindre 1 à 2 cm.In the example shown, the section of the head of the stud has a rectangular shape; in a variant, said section has an oval or oblong shape. The flat part of the connecting piece is made of metal; it measures about 130 to 190 mm by 300 to 400 mm, and has a thickness of about 6 to 10 mm. The stud has a length about 40 to 80 mm and a diameter of about 14 to 19 mm. The dimensions of the flat part and the stud are chosen according to the dimensions of the panel to be fixed, the slab and the desired mechanical strength. The diameter of the stud is chosen equal to or slightly less than the width of the light 240. Thus, when the stud is positioned in the light, the panel is immobilized in a horizontal plane. The length of the stud is chosen to allow on the one hand to make up the defects in thickness and / or positioning of the slab, which are commonly of the order of a few millimeters to 2 to 4 cm, without damaging the panel whose dimension is perfectly controlled from one panel to another, and on the other hand to absorb a possible deflection of the slab due to a load variation of the slab, bending which can reach 1 to 2 cm.

La pièce plate de la pièce de liaison comprend également à une deuxième extrémité opposée à la première extrémité deux trous 341, 342 de fixation, permettant de solidariser la pièce de liaison 200 sur la dalle 100 à l'aide d'un organe de fixation tel qu'une vis, un goujon, une tige filetée, etc., sans avoir recours à un outil pour percer la pièce plate métallique de la pièce de liaison.The flat part of the connecting piece also comprises at a second end opposite the first end two fixing holes 341, 342, making it possible to secure the connecting piece 200 to the slab 100 by means of a fixing member such as a screw, a stud, a threaded rod, etc., without using a tool to drill the flat metal part of the connecting piece.

Les figures 7 à 9 montrent comment positionner la pièce de liaison 300 sur l'étrier 200. La pièce de liaison est positionnée au dessus de l'étrier, de sorte que la grande dimension de la tête du goujon s'étende dans l'axe principal de la lumière 240 de l'étrier (figure 7). La pièce de liaison est ensuite abaissée pour que la tête du goujon traverse la lumière, puis la pièce de liaison est tournée de 90° (figure 8, 9), puis la pièce de liaison est fixée par un organe de fixation tel qu'une vis, un goujon, une tige filetée, etc. sur la dalle 100. Les dimensions de la tête du goujon sont telles que la tête ne peut pas ressortir de la lumière 240, et en conséquence le panneau ne peut pas se décrocher. Ainsi, même si le pied du panneau se décroche, le haut du panneau reste attaché à la dalle. Par contre, la pièce de liaison n'est pas fixée rigidement à l'étrier car le goujon peut coulisser dans la lumière, selon la direction longitudinale du pontet et selon l'axe du goujon. Le pied du panneau étant fixé rigidement, une fixation non rigide en haut du panneau permet de ne pas déformer ou rompre le panneau et / ou la pièce de liaison en cas de mouvement de la dalle 100 selon la direction longitudinale du pontet, par exemple en cas de séisme, ou en cas de mouvement de la dalle selon l'axe du goujon, par exemple en cas de variation de la charge de la dalle. La longueur de la lumière 240 peut être choisie en fonction des normes antisismiques, par exemple de l'ordre de 7 à 11 centimètres.The Figures 7 to 9 show how to position the connecting piece 300 on the stirrup 200. The connecting piece is positioned above the stirrup, so that the large dimension of the head of the stud extends in the main axis of the light 240 of the stirrup ( figure 7 ). The connecting piece is then lowered so that the head of the stud passes through the light, then the connecting piece is rotated by 90 ° ( figure 8, 9 ), and then the connecting piece is fixed by a fastener such as a screw, a stud, a threaded rod, etc. on the slab 100. The dimensions of the head of the stud are such that the head can not emerge from the light 240, and therefore the panel can not fall out. Thus, even if the foot of the panel is unhooked, the top of the panel remains attached to the slab. By cons, the connecting piece is not rigidly attached to the stirrup because the stud can slide in the light in the longitudinal direction of the bridge and along the axis of the stud. The foot of the panel being rigidly fixed, a non-rigid attachment at the top of the panel makes it possible not to deform or break the panel and / or the connecting piece in the event of movement of the slab 100 in the longitudinal direction of the bridge, for example in case of earthquake, or in case of movement of the slab along the axis of the stud, for example in case of variation of the load of the slab. The length of the light 240 may be chosen according to the antiseismic standards, for example of the order of 7 to 11 centimeters.

La pièce de liaison représentée sur les figures comprend également une ailette 350 plane fixée sur la pièce plate de la pièce de liaison 300 ; l'ailette s'étend depuis une face de dessus de la pièce plate (face opposée au goujon) dans un plan qui est perpendiculaire au plan principal de la pièce plate ; la dite ailette comprend au moins un trou de fixation. L'ailette sert à positionner et à fixer le pied d'un deuxième panneau venant au dessus du premier. Bien sûr, une telle ailette n'est pas nécessaire si aucun panneau ne doit être fixé au dessus du premier panneau. L'ailette est fixée sur la pièce plate 305 de sorte à être dans le même plan que la deuxième paroi 420 de l'équerre 400. Ceci permet de garantir un alignement parfait des panneaux les uns au dessus des autres.The connecting piece shown in the figures also comprises a fin 350 plane fixed on the flat part of the connecting piece 300; the fin extends from a top face of the flat piece (face opposite the stud) in a plane which is perpendicular to the main plane of the flat piece; said fin comprises at least one fixing hole. The fin is used to position and fix the foot of a second panel coming above the first. Of course, such a fin is not necessary if no panel is to be fixed above the first panel. The fin is fixed on the flat piece 305 so as to be in the same plane as the second wall 420 of the bracket 400. This ensures a perfect alignment of the panels one above the other.

Enfin, la pièce plate 305 de la pièce de liaison 300 représentée comprend un évidement 370, de forme rectangulaire. Cet évidement ne joue aucun rôle pour la fixation du panneau, il permet simplement une économie de matière et de poids. En pratique, la matière enlevée correspond à la pièce de renfort 250 positionnée sous le pontet 220 du sabot de l'étrier.Finally, the flat part 305 of the connecting piece 300 shown comprises a recess 370, of rectangular shape. This recess plays no role in fixing the panel, it simply saves material and weight. In practice, the material removed corresponds to the reinforcing member 250 positioned under the bridge 220 of the caliper shoe.

Dans les exemples représentés, le système selon l'invention comprend également une équerre 400 de positionnement comprenant une première paroi 410 et une deuxième paroi 420 perpendiculaire à la première paroi ; la première paroi 410 de l'équerre est destinée à venir en appui sur une face de dessus de la dalle 100 et sur la face de dessous de la pièce plate 305 ; la paroi latérale 230 de l'étrier est destinée à venir en appui sur la deuxième paroi 420 de l'équerre. L'équerre permet de rattraper les éventuels défauts de la dalle ou de la poutre : la première paroi 410 permet d'avoir un appui parfaitement plan pour la pièce de liaison 300 ce qui permet de fixer solidement la pièce de liaison à la dalle ou à la poutre sans risque de la déformer ; la deuxième paroi 420 permet un appui parfaitement plan du panneau, y compris dans le cas où le bord de la dalle présente un défaut de verticalité ou de planéité. L'équerre est simplement posée sur le bord de la dalle ; elle n'assume en pratique aucune reprise d'efforts mécaniques.In the examples shown, the system according to the invention also comprises a positioning bracket 400 comprising a first wall 410 and a second wall 420 perpendicular to the first wall; the first wall 410 of the bracket is intended to bear on a top face of the slab 100 and on the underside of the flat part 305; the side wall 230 of the yoke is intended to bear against the second wall 420 of the bracket. The bracket makes it possible to make up for any defects in the slab or beam: the first wall 410 makes it possible to have a perfectly flat support for the connecting piece 300, which makes it possible to firmly fix the connecting piece to the slab or to the slab. the beam without risk of deforming it; the second wall 420 allows a perfectly flat support panel, including in the case where the edge of the slab has a defect of verticality or flatness. The square is simply placed on the edge of the slab; it does not assume in practice any recovery of mechanical forces.

La première paroi de l'équerre comprend également au moins un trou de fixation, permettant à l'aide d'une vis de fixer temporairement l'équerre, le temps de la mise en place de la pièce de liaison.The first wall of the bracket also comprises at least one fixing hole, allowing the use of a screw to temporarily fix the square, the time of establishment of the connecting piece.

La première paroi 410 de l'équerre comprend, à une extrémité opposée à la deuxième paroi 420 de l'équerre, deux découpes 431, 432 ouvertes débouchant sur un côté latéral de la première paroi de l'équerre. Les découpes permettent le passage des organes de fixation (vis, goujon, tige filetée, etc.) de la pièce de liaison sur la dalle.The first wall 410 of the bracket comprises, at an end opposite the second wall 420 of the bracket, two open cutouts 431, 432 opening on a lateral side of the first wall of the bracket. The cuts allow the passage of the fasteners (screw, stud, threaded rod, etc.) of the connecting piece on the slab.

La première paroi de l'équerre comprend deux repères visuels 441, 442 positionnés sur les côtés latéraux de la première paroi 410 de l'équerre, à une distance prédéfinie (par exemple 2 à 4 cm) de la deuxième paroi 420 de l'équerre. Lors de la mise en place de l'équerre, ces repères visuels doivent être positionnés sur la face de dessus de la dalle ou de la poutre; si ces repères sont en dehors de la dalle, on considère que le défaut de planéité et de verticalité du flanc de la dalle 100 est trop important, et que dans ces conditions le système de fixation selon l'invention ne peut pas être mis en place correctement. Les repères visuels informent ainsi des limites mécaniques de l'équerre et sécurisent son utilisation. Les repères visuels peuvent être de tous types : encoches, traits, marquages, etc.The first wall of the bracket comprises two visual markers 441, 442 positioned on the lateral sides of the first wall 410 of the bracket, at a predefined distance (for example 2 to 4 cm) from the second wall 420 of the bracket. . When placing the square, these visual cues must be positioned on the top face of the slab or beam; if these marks are outside the slab, it is considered that the lack of flatness and verticality of the sidewall of the slab 100 is too great, and that in these conditions the fastening system according to the invention can not be implemented. correctly. The visual cues thus inform the mechanical limits of the square and secure its use. The visual cues can be of all types: notches, lines, markings, etc.

Enfin, dans les exemples représentés, le système selon l'invention comprend également une cale 500 (figure 4) de mise à niveau, présentant un trou 510 adapté à un diamètre de la première extrémité 320 du goujon dépassant sur la face de dessus de la pièce de liaison pour former une sorte de pion ; la cale est destinée à être positionnée sur la pièce de liaison et à être maintenue en position dans le plan de la pièce de liaison par la première extrémité du goujon. La cale est en pratique une petite pièce de liaison plane, d'épaisseur de quelques millimètres à 2 à 4 cm. Les panneaux ont une dimension parfaite, correspondant par exemple à une hauteur d'étage d'un bâtiment. La cale permet de rattraper les défauts d'épaisseur ou de positionnement de la dalle, qui sont couramment de l'ordre de quelques millimètres à 2 à 4 cm. Les systèmes de fixation sont positionnés par exemple tous les 1,5 à 2 m, sur toute la longueur d'un bâtiment. L'utilisation de cales permet d'obtenir un niveau parfaitement horizontal sur toute la longueur du bâtiment pour fixer au mieux les panneaux.Finally, in the examples shown, the system according to the invention also comprises a shim 500 ( figure 4 ) leveling, having a hole 510 adapted to a diameter of the first end 320 of the stud protruding on the top face of the connecting piece to form a kind of pin; the wedge is intended to be positioned on the connecting piece and to be held in position in the plane of the connecting piece by the first end of the stud. The wedge is in practice a small flat connecting piece, with a thickness of a few millimeters to 2 to 4 cm. The panels have a perfect size, corresponding for example to a floor height of a building. The wedge makes it possible to make up for defects in the thickness or positioning of the slab, which are commonly of the order of a few millimeters to 2 to 4 cm. Fixing systems are positioned for example every 1.5 to 2 m, over the entire length of a building. The use of wedges makes it possible to obtain a perfectly horizontal level along the whole length of the building in order to fix the panels as well as possible.

A noter que, pour garantir l'isolation thermique et / ou acoustique d'un mur constitué de panneaux fixés à l'aide de systèmes de fixation selon l'invention, on prévoit de remplir l'espace entre deux panneaux, l'espace entre la deuxième paroi 420 (verticale) de l'équerre et le bord de la dalle ou de la poutre par un matériau isolant compressible.It should be noted that, in order to guarantee the thermal and / or acoustic insulation of a wall consisting of panels fastened using fixing systems according to the invention, provision is made to fill the space between two panels, the space between the second wall 420 (vertical) of the bracket and the edge of the slab or beam by a compressible insulating material.
