Description

PLANCHER La présente invention concerne un plancher comprenant des planches montées sur une charpente comprenant des solives, lesdites planches et solives comprenant sur chacun de leurs flancs latéraux au moins une rainure latérale, lesdites planches étant reliées aux solives à l'aide d'organes d'accouplement, chaque organe d'accouplement comprenant une première aile agencée pour prendre prise dans la rainure latérale de la solive et une deuxième aile agencée pour prendre prise dans la rainure latérale de la planche, la première et la deuxième aile étant décalées en hauteur l'une par rapport à l'autre et reliées entre elles par un montant, ladite deuxième aile est composée de deux parties qui s'étendent de part et d'autre du montant dans une première et deuxième direction sensiblement opposées l'une à l'autre. De tels planchers sont connus et commercialisés par la société ECTORS B.V.B.A. à Sint-Truiden sous la marque zero-connect. Ces planchers sont par exemple utilisés sur des terrasses. Pour placer un tel plancher on étend d'abord les solives sur le sol ou une toiture. Ensuite, les planches sont fixées aux solives à l'aide des organes d'accouplement. La première aile de l'organe d'accouplement prend prise dans la solive alors que la deuxième aile prend prise dans la planche. Le plancher peut ainsi être construit sans devoir visser ou clouer, ce qui rend le montage facile et rapide et permet également de faciliter le démontage. Un inconvénient des planchers connus est que l'organe d'accouplement ne permet pas un ancrage solide dans la solive. En effet, la première aile n'a qu'une courte longueur et ne prend appui que sur une petite surface. Ceci peut alors occasionner un détachement de l'organe d'accouplement non seulement lors du montage, ce qui entrave le montage, mais également lorsque le plancher est posé, ce qui entrave la fiabilité de la construction. L'invention a pour but de réaliser un plancher où la liaison entre les solives et les planches est plus fiable et cause moins de problèmes lors du montage du plancher. A cette fin, un plancher suivant l'invention est caractérisé en ce que ladite première aile est composée de deux parties qui s'étendent de part et d'autre du montant dans un même plan s'étendant suivant une troisième direction sensiblement perpendiculaire à la première et à la deuxième direction. Le fait que la première aile comporte deux parties permet de réaliser une liaison avec la solive qui s'étend sur une plus grande surface. Une liaison plus fiable tant lors du montage que dans le temps est ainsi obtenue. De plus, puisque la première aile s'étend sensiblement perpendiculaire à la deuxième, la liaison est réalisée dans des plans opposés, ce qui rend sensiblement plus difficile le décrochage de l'organe d'accouplement lorsque le plancher est posé. Une première forme de réalisation préférentielle d'un plancher suivant l'invention est caractérisée en ce que les deux parties de la deuxième aile sont situées dans le prolongement l'une de l'autre. Ceci permet d'équilibrer la liaison entre deux planches adjacentes. Une deuxième forme de réalisation préférentielle d'un plancher suivant l'invention est caractérisée en ce que chaque partie d'aile est formée par une aile ayant une géométrie en bi-plan. La géométrie en biplan permet de donner une certaine élasticité à l'aile et de faciliter ainsi son introduction dans la rainure latérale. De préférence chaque aile comporte sur sa face frontale un ergot. La présence d'un ergot renforce l'accrochage dans la rainure latérale. Une troisième forme de réalisation préférentielle d'un plancher suivant l'invention est caractérisée en ce que ledit montant s'étend au delà du plan dans lequel est situé la deuxième aile. Ainsi un espace est créé entre deux planches adjacentes. Une quatrième forme de réalisation préférentielle d'un plancher suivant l'invention est caractérisée en ce que la charpente comporte un plot agencé pour une mise à hauteur du plancher par rapport à un sol sur lequel le plot est placé, ledit plot étant muni d'une pièce intermédiaire agencée pour positionner la solive par rapport au plot. Le plot permet de mettre le plancher à niveau par rapport au sol. De préférence la solive est pourvue d'une autre rainure longitudinale et la pièce intermédiaire est pourvue de perforations, de telle façon à ce que lorsque la solive est placée sur le plot ladite autre rainure et les perforations sont situées à même hauteur. Ceci facilite la fixation du plot et des solives. L'invention sera maintenant décrite plus en détail à l'aide des dessins qui représentent une forme de réalisation d'un plancher suivant l'invention. Dans les dessins : la figure 1 illustre une vue détaillée d'une fraction d'un plancher monté sur un plot; la figure 2 montre une vue détaillée d'un organe d'accouplement; la figure 3 montre une vue en coupe à travers d'une solive; la figure 4 montre une vue en coupe à travers d'une planche; et la figure 5 une vue détaillée de la pièce intermédiaire montée sur la tête d'un plot. Dans les dessins, une même référence a été attribuée à un même élément ou à un élément analogue. Le plancher 1 suivant l'invention, illustré à la figure 1 , comporte une série de planches 3 disposées sur des solives 2. La liaison entre planches et solives est réalisée à l'aide d'organes d'accouplement 4. Chaque organe d'accouplement 4 est disposé entre deux planches 3 adjacentes et prend prise dans ces deux planches. L'organe d'accouplement prend également prise dans la solive 2. Cette dernière peut être posée sur un plot 6 à l'aide d'une pièce intermédiaire 5. Il faut toutefois noter que l'emploi de plots n'est pas indispensable pour la réalisation d'un plancher suivant l'invention. Les plots sont une solution optionnelle qui est utilisée soit si l'on désire rehausser le niveau du plancher par rapport au sol sur lequel ils est posé ou si le sol est en pente ou inégal et que l'on désire avoir le plancher à un même niveau. La fixation des planches aux solives est réalisée à l'aide d'organes d'accouplement illustrés à la figure 2. Chaque organe 4 d'accouplement comporte une première aile 9-a et 9-b qui forme l'extrémité du pied 7 de l'organe. La première aile est composée de deux parties 9-a et 9-b qui s'étendent dans un même plan de part et d'autre d'un montant 8 placé sensiblement perpendiculaire par rapport au pied 7. Les deux parties 9-a et 9-b de la première aile sont séparées par un espace 15 ayant une largeur qui correspond à celle du montant 8. L'organe d'accouplement comporte également une deuxième aile 11 , 12 qui est décalée en hauteur par rapport à la première aile. La deuxième aile comporte une première partie 11 et une seconde partie 12 séparées entre elles par le montant 8. La première partie 11 s'étend dans une première direction (flèche a) et la seconde partie 12 dans une deuxième direction (flèche b) qui sont sensiblement opposées l'une à l'autre et perpendiculaires par rapport au montant. Les premières et deuxièmes directions sont quant à elles sensiblement perpendiculaires à une troisième direction (flèche c) suivant laquelle s'étend la première aile 9. Les ailes, le montant et le pied sont de préférence formés d'une seule pièce, de préférence en matière synthétique ce qui empêche la rouille. Bien entendu d'autres matières peuvent être utilisées comme de l'acier ou du bois. Chaque aile 9, 11 , 12 possède de préférence une géométrie en bi-plan formée par les ailettes 9-c et 9-d, respectivement 11-c et 11 -d, 12-c et 12-d. Les ailettes ainsi obtenues sont alors séparées en hauteur par un espace 13. Chaque ailette comporte de préférence sur sa face frontale un ergot 10. L'ergot possède de préférence un front arrondi, qui s'étend sensiblement perpendiculaire par rapport au plan de l'aile. La géométrie en bi-plan permet de donner plus d'élasticité à l'aile, facilitant ainsi le montage dans les planches ou la solive et améliorant la prise après montage. Le montant s'étend au delà du plan dans lequel est située la deuxième aile grâce à une saillie 16. Ceci permet de laisser une distance, égale à l'épaisseur de la saillie, entre deux planches adjacentes. Comme illustré aux figures 1 , 3 et 4, la solive 2 comporte sur chacun de ses flancs latéraux une première rainure 18 et de préférence une seconde rainure 19. Chaque planche 3 comporte sur chacun de ses flancs latéraux une rainure 20. Les rainures 18, T9 et 20 s'étendent de préférence sur toute la longueur de la solive ou de la planche, ce qui facilite la pose de l'organe d'accouplement. Les rainures 18 et 20 ont une géométrie sensiblement en forme d'oméga Çl) comportant une partie de fond plus large que la partie d'entrée. Pour monter le plancher suivant l'invention, on applique d'abord les solives soit directement sur le sol ou sur un toit, soit sur des plots 6 disposés au préalable. Après placement des solives les organes d'accouplement sont introduits à l'aide de leurs premières ailes 9 dans la première rainure 18 de la solive. Bien entendu il est également possible de d'abord appliquer les premières ailes et d'ensuite placer les solives. L'élasticité que procure la géométrie en bi-plan facilite l'introduction de la première aile dans la rainure 18. L'ergot 10 quant à lui va coopérer avec la géométrie en Ω de la rainure pour venir prendre prise dans la partie la plus large. Le front arrondi de l'ergot va faciliter l'introduction dans la rainure. Enfin, après introduction, l'élasticité des ailes va provoquer une remise à l'état de repos des ailes, appliquant ainsi une force à l'intérieur de la rainure permettant de bien maintenir en place la première aile dans la rainure et garantissant une liaison fiable entre solive et organe d'accouplement. Ensuite les planches sont disposées sur les solives et bien de telle façon que plancher et solives sont dans des directions sensiblement perpendiculaires entre elles. La rainure 20 de la planche est poussée contre la deuxième aile de telle façon à ce eue cette dernière vienne s'introduire dans la rainure 20. Bien entendu l'épaisseur de la planche et la position de la rainure sont choisies de telle façon à correspondre au positionnement de la deuxième aile sur l'organe d'accouplement. La géométrie en bi-plan et en oméga produit les mêmes avantages que ceux décrits au préalable pou r la solive. Puisque la deuxième aile comporte deux parties qui s'étendent de part et d'autre du montant, l'organe d'accouplement permet de fixer deux planches adjacentes à la solive. De plus, puisque les premières et deuxièmes ailes s'étendent dans des directions perpendiculaires entre elles, un éventuel mouvement des planches n'aura pas d'effet sur la fixation de l'organe d'accouplement à la solive. Comme illustré aux figures 1 et 5, les planches et les solives peuvent être montées sur des plots 6 à l'aide d'une pièce intermédiaire 5, elle même fixée au plot, par exemple à l'aide d'une goupille 26. La pièce intermédiaire est pourvue de perforations 25 appliquées sur des montants 27 qui délimitent un premier canal agencé pour être traversé par une solive. Les perforations sont placées à une telle hauteur que lorsque la solive est placée sur le plot, la rainure 19 et les perforations sont situées à même hauteur. Ainsi, on peut fixer la solive à la pièce intermédiaire et donc au plot en introduisant par exemple des goupilles dans les perforations et la rainure 19. La pièce intermédiaire comporte également une première 23 et une seconde 24 encoche pour recevoir une extrémité d'une solive. Les encoches étant positionnées face à face et perpendiculaires par rapport au canal. FLOOR The present invention relates to a floor comprising boards mounted on a frame comprising joists, said boards and joists comprising on each of their lateral flanks at least one lateral groove, said boards being connected to the joists by means of coupling, each coupling member comprising a first wing arranged to take hold in the lateral groove of the joist and a second wing arranged to take hold in the lateral groove of the board, the first and the second wing being offset in height one with respect to the other and connected together by an upright, said second wing is composed of two parts which extend on either side of the upright in a first and second direction substantially opposite to each other . Such floors are known and marketed by the company ECTORS BVBA in Sint-Truiden under the brand zero-connect. These floors are for example used on terraces. To place such a floor, first extend the joists on the floor or a roof. Then the planks are attached to the joists using the coupling members. The first wing of the coupling member takes hold in the joist while the second wing takes hold in the board. The floor can thus be constructed without having to screw or nail, which makes assembly quick and easy and also makes it easier to dismantle. A disadvantage of known floors is that the coupling member does not allow solid anchoring in the joist. Indeed, the first wing has only a short length and is supported only on a small surface. This can then cause detachment of the coupling member not only during assembly, which hinders assembly, but also when the floor is laid, which hinders the reliability of the construction. The object of the invention is to produce a floor where the connection between the joists and the boards is more reliable and causes fewer problems during the mounting of the floor. To this end, a floor according to the invention is characterized in that said first wing is composed of two parts which extend on either side of the upright in the same plane extending in a third direction substantially perpendicular to the first and second direction. The fact that the first wing has two parts makes it possible to make a connection with the joist which extends over a larger area. A more reliable connection both during assembly and over time is thus obtained. In addition, since the first wing extends substantially perpendicular to the second, the connection is made in opposite planes, which makes it significantly more difficult to detach the coupling member when the floor is laid. A first preferred embodiment of a floor according to the invention is characterized in that the two parts of the second wing are located in the extension of one another. This makes it possible to balance the connection between two adjacent boards. A second preferred embodiment of a floor according to the invention is characterized in that each wing part is formed by a wing having a bi-plane geometry. The biplane geometry allows to give a certain elasticity to the wing and thus facilitate its introduction into the lateral groove. Preferably, each wing has a lug on its front face. The presence of a lug strengthens the grip in the lateral groove. A third preferred embodiment of a floor according to the invention is characterized in that said upright extends beyond the plane in which the second wing is located. Thus a space is created between two adjacent boards. A fourth preferred embodiment of a floor according to the invention is characterized in that the frame comprises a stud arranged for an elevation of the floor relative to a floor on which the stud is placed, said stud being provided with an intermediate piece arranged to position the joist relative to the stud. The stud allows you to level the floor relative to the ground. Preferably the joist is provided with another longitudinal groove and the intermediate piece is provided with perforations, so that when the joist is placed on the stud said other groove and the perforations are located at the same height. This facilitates the fixing of the stud and the joists. The invention will now be described in more detail using the drawings which show an embodiment of a floor according to the invention. In the drawings: FIG. 1 illustrates a detailed view of a fraction of a floor mounted on a stud; Figure 2 shows a detailed view of a coupling member; Figure 3 shows a sectional view through a joist; Figure 4 shows a sectional view through a board; and Figure 5 a detailed view of the intermediate piece mounted on the head of a pad. In the drawings, the same reference has been assigned to the same element or to an analogous element. The floor 1 according to the invention, illustrated in Figure 1, comprises a series of boards 3 arranged on joists 2. The connection between boards and joists is produced using coupling members 4. Each coupling member 4 is arranged between two adjacent boards 3 and takes hold in these two boards. The coupling member also takes hold in the joist 2. The latter can be placed on a stud 6 using an intermediate piece 5. It should however be noted that the use of studs is not essential for the production of a floor according to the invention. The studs are an optional solution which is used either if you wish to raise the level of the floor compared to the ground on which they are placed or if the ground is sloping or uneven and you wish to have the floor at the same level. The boards are attached to the joists using coupling members illustrated in FIG. 2. Each coupling member 4 has a first wing 9-a and 9-b which forms the end of the foot 7 of the organ. The first wing is composed of two parts 9-a and 9-b which extend in the same plane on either side of an upright 8 placed substantially perpendicular to the foot 7. The two parts 9-a and 9-b of the first wing are separated by a space 15 having a width which corresponds to that of the upright 8. The coupling member also comprises a second wing 11, 12 which is offset in height relative to the first wing. The second wing has a first part 11 and a second part 12 separated from each other by the upright 8. The first part 11 extends in a first direction (arrow a) and the second part 12 in a second direction (arrow b) which are substantially opposite to each other and perpendicular to the upright. The first and second directions are for their part substantially perpendicular to a third direction (arrow c) along which the first wing 9 extends. The wings, the upright and the foot are preferably formed in one piece, preferably in synthetic material which prevents rust. Of course, other materials can be used such as steel or wood. Each wing 9, 11, 12 preferably has a bi-plane geometry formed by the fins 9-c and 9-d, respectively 11-c and 11 -d, 12-c and 12-d. The fins thus obtained are then separated in height by a space 13. Each fin preferably has on its front face a lug 10. The lug preferably has a rounded front, which extends substantially perpendicular to the plane of the wing. The bi-plane geometry makes it possible to give more elasticity to the wing, thus facilitating assembly in boards or joists and improving grip after assembly. The amount extends beyond the plane in which the second wing is located by a projection 16. This allows to leave a distance, equal to the thickness of the projection, between two adjacent boards. As illustrated in FIGS. 1, 3 and 4, the joist 2 has on each of its lateral flanks a first groove 18 and preferably a second groove 19. Each board 3 has on each of its lateral flanks a groove 20. The grooves 18, T9 and 20 preferably extend over the entire length of the joist or the plank, which facilitates the fitting of the coupling member. The grooves 18 and 20 have a geometry substantially in the form of an omega (C1) comprising a bottom portion which is wider than the inlet portion. To mount the floor according to the invention, the joists are first applied either directly on the floor or on a roof, or on studs 6 arranged beforehand. After placing the joists, the coupling members are introduced using their first wings 9 into the first groove 18 of the joist. Of course it is also possible to first apply the first wings and then place the joists. The elasticity provided by the bi-plane geometry facilitates the introduction of the first wing into the groove 18. The lug 10 will cooperate with the geometry in Ω of the groove to take hold in the widest part. The rounded front of the lug will facilitate the introduction into the groove. Finally, after introduction, the elasticity of the wings will cause the wings to return to the resting state, thus applying a force inside the groove allowing the first wing to be properly held in place in the groove and guaranteeing a connection. reliable between joist and coupling member. Then the boards are placed on the joists and so that the floor and joists are in directions substantially perpendicular to each other. The groove 20 of the board is pushed against the second wing so that the latter comes into the groove 20. Of course, the thickness of the board and the position of the groove are chosen so as to correspond positioning of the second wing on the coupling member. The bi-plane and omega geometry produces the same advantages as those previously described for the joist. Since the second wing has two parts which extend on either side of the upright, the coupling member makes it possible to fix two boards adjacent to the joist. In addition, since the first and second wings extend in directions perpendicular to each other, any movement of the boards will have no effect on the attachment of the coupling member to the joist. As illustrated in FIGS. 1 and 5, the boards and the joists can be mounted on studs 6 using an intermediate piece 5, itself fixed to the stud, for example using a pin 26. The intermediate piece is provided with perforations 25 applied to uprights 27 which delimit a first channel arranged to be crossed by a joist. The perforations are placed at such a height that when the joist is placed on the stud, the groove 19 and the perforations are located at the same height. Thus, we can fix the joist to the intermediate piece and therefore to the stud by introducing, for example, pins into the perforations and the groove 19. The intermediate piece also includes a first 23 and a second 24 notch to receive one end of a joist. The notches being positioned face to face and perpendicular to the channel.
