Description

La présente invention a pour objet des moyens pour la mise en place do plafonds suspendus sous des poutres ou poutrelles préfabriquées supportant ou non une dalle de répartition ou un plancher de toute autre nature.The present invention relates to means for the establishment of suspended ceilings under beams or prefabricated beams supporting or not a distribution slab or a floor of any other kind.

Différents systèmes ont déjà été proposés pour la fixation de plafonds suspendus. En particulier, il a été proposé de prévoir à la fabrication des poutrelles, des trous permettant, ensuite d'accrocher des suspentes, ou des douilles noyées dans le même but.Different systems have already been proposed for fixing suspended ceilings. In particular, it has been proposed to provide for the production of beams, holes allowing, then to hang lines, or sockets embedded for the same purpose.

On a également proposé de fixer aux poutrelles, au moment de leur fabrication, des semelles do bois convenablement ancrées (clous galvanisés croisés etc...).It has also been proposed to fix to the beams, at the time of their manufacture, wooden soles suitably anchored (crossed galvanized nails, etc.).

Il est également connu d'utiliser des suspentes spéciales prenant appui sur les poutrelles, dont l'extrémité supérieure se trouve noyée dans la dalle de répartition.It is also known to use special lines bearing on the beams, the upper end of which is embedded in the distribution slab.

Les défauts de ces divers moyens tiennent à ce que les poutres ou poutrelles ne sont pas rigoureusement rectilignos et comportent une légère courbure ou contre-flèche qui peut atteindre plusieurs centimètres ; il est dès lors nécessaire de rattraper cette contre-flèche ou les inégalités de la poutrelle au moment de la mise en place du plafond suspendu, ce qui suppose des variations de longueur des suspentes et la possibilité de régler la longueur de ces dernières à la demande. Ces réglages entrai- nont une grande dépense de main d'oeuvre sur chantier.The shortcomings of these various means are that the beams or beams are not rigorously straight and have a slight curvature or counter-jib which can reach several centimeters; it is therefore necessary to make up for this counter-jib or the unevenness of the beam at the time of the installation of the suspended ceiling, which supposes variations in length of the lines and the possibility of adjusting the length of the latter on demand . These adjustments will entail a large expenditure of labor on site.

D'autre part, pour être économique, il faur que le système employé soit facile à mettre en oeuvre au moment de la fabrication de la poutrelle et qu'il ne présente -pas d'inconvénient pour le stockage et le transport de ces dernières, ce qui exclut les solutions comportant des organes incoporés protubérants.On the other hand, to be economical, it should be that the system used is easy to implement at the time of manufacture of the beam and that it does not present any inconvenience for the storage and transport of the latter, which excludes solutions comprising protruding incoporated organs.

L'invention a pour but un système répondant à ces impératifs et elle a pour objet :

  • Une poutrelle munie de moyens de fixations simples et réglables en hauteur pour des lattes, semellos ou lambourdes do bois sur lesquels sera fixé le plafond.
The object of the invention is to provide a system which meets these requirements and its subject is:
  • A beam provided with simple fixing means and adjustable in height for wooden slats, beams or joists on which the ceiling will be fixed.

Lo procédé selon l'invontion consiste à déplier ou plier les pattes jusqu'à co que los fourreaux des clous soient approximativomont dans un même plan horizontal et à fixer des lattos, lambourdes ou semelles entre les pattes au moyen do clous insérés dans lesdits fourreaux en plaçant leurs sous-faces dans un môme plan horizontal. Le plafond peut alors être accroché auxditos lattes.The method according to the invention consists in unfolding or bending the legs until the sheaths of the nails are approximately in the same horizontal plane and in fixing lattos, joists or soles between the legs by means of nails inserted in said sheaths. placing their undersides in the same horizontal plane. The ceiling can then be hung on said slats.

On voit que le procédé est extrêmement simple et pratique, et que les moyens de l'invention assurent une économie considérable de main d'oeuvre sur le chantier en même temps qu'une pose rigoureuse.We see that the process is extremely simple and practical, and that the means of the invention provide a considerable saving of labor on the site at the same time as a rigorous installation.

Do plus, les lattes ainsi posées, du fait que les pattes ont été repliées à des angles différents et opposés, sont très rigidement fixées par rapport aux poutrelles et leur position ost pratiquement invariable.Do more, the slats thus posed, because the legs have been folded at different and opposite angles, are very rigidly fixed relative to the beams and their position ost practically invariable.

Los dispositions qui précèdent, ainsi que certaines autres caractéristiques de l'invention sont décrites ci-après avec référence au dessin annexe sur lequel :

  • La figure 1 est une illustration schématique en perspective et coupe des moyens dispositifs et procédés de l'invention ;
  • La figure 2 illustre en perspective et coupe partielle une poutrelle selon l'invention à l'envers ;
  • La figure 3 est une variante de la figure 2 ;
  • Les figures 4 à 10 sont des variantes de réalisation -de l'insert selon l'invention,
The foregoing provisions, as well as certain other characteristics of the invention are described below with reference to the accompanying drawing in which:
  • Figure 1 is a schematic perspective illustration and section of the device means and methods of the invention;
  • Figure 2 illustrates in perspective and partial section a beam according to the invention upside down;
  • Figure 3 is a variant of Figure 2;
  • FIGS. 4 to 10 are alternative embodiments of the insert according to the invention,

En se reportant aux figures 1 à 3, on voit que la poutrelle 1, selon l'invention, comporte des pattes 2 ancrées dans le béton du talon de la poutrolle, do part et d'autre de son plan médian longitudinal matérialisé par les axes XX et YY sur la figure 2, approximativement équidistants de ce plan d'environ 2 à 3 cm ; la longueur des parties des pattes 2 qui dépassent de la poutrelle est voisine de celle de la contre-flècho maximale admissible pour la poutrelle, en pratique do l'ordre do 3 à 6 cm ; les pattes 2 sont terminées par des fourreaux 3 permettant l'insertion de clous 4 perpendiculairement au plan XX, YY.Referring to Figures 1 to 3, we see that the beam 1, according to the invention, has legs 2 anchored in the concrete of the heel of the beam, do on either side of its longitudinal median plane materialized by the axes XX and YY in FIG. 2, approximately equidistant from this plane of approximately 2 to 3 cm; the length of the parts of the legs 2 which protrude from the beam is close to that of the maximum allowable counter-deflection for the beam, in practice of the order of 3 to 6 cm; the legs 2 are terminated by sleeves 3 allowing the insertion of nails 4 perpendicular to the plane XX, YY.

Ainsi, comme représenté figure 1, on repliant plus ou moins (ou en relevant plus ou moins) les pattes 2, on peut fixer des lattes 5 en réglant leur distance à la sous-face de la poutrelle 1, La fixation des lattes 5 est obtenue par enfoncement dos clous 4 lorsque leur mise en place est satisfaisante, c'est-à-dire lorsque les sous-faces des lattes 5 sont dans un même plan horizontal ; on peut alors fixer directement le plafond suspendu 6 sur les lattes 5.Thus, as shown in FIG. 1, by folding more or less (or by raising more or less) the legs 2, it is possible to fix the slats 5 by adjusting their distance to the underside of the beam 1, The fixing of the slats 5 is obtained by driving back nails 4 when their installation is satisfactory, that is to say when the undersides of the slats 5 are in the same horizontal plane; we can then directly attach the suspended ceiling 6 to the slats 5.

La simplicité du système ot de sa mise on oeuvre résulte do ce qui précède ; il suffit d'un marteau ou d'une pince pour replier ou déplier les pattes 2 jusqu'à les régler convenablement . Los-pattes sont do préférence initialement ropliées à 90° dans la direction de l'axe longitudinal XX les unes dans un sons los autres en sens opposé (figure 2).The simplicity of the system and its implementation results from the above; a hammer or pliers are enough to fold or unfold the tabs 2 until they are properly adjusted. The legs are preferably initially rotated at 90 ° in the direction of the longitudinal axis XX, one in a different sound in the opposite direction (FIG. 2).

De cette façon, lorsque les clous 4 sont enfoncés dans les lattes 5 la disposition des pattos rend pratiquement impossible de déplacer les lattes 5 par rapport aux poutrelles 1 aussi bien longitudinalement qu'en hauteur. Cette rigidité de liaison est-un avantage très important.In this way, when the nails 4 are driven into the slats 5, the arrangement of the pattos makes it practically impossible to move the slats 5 relative to the beams 1 both longitudinally and in height. This bonding rigidity is a very important advantage.

Dans les figures 1 et 2, on a représenté la disposition préférée des pattes par paires dont les parties ancrées sont dans un même plan transversal à la poutre. En variante, la figure 3 montre que les pattes peuvent être disposées autrement, par exemple alternativement d'un côté et de l'autre du plan médian longitudinal la long de l'extension longitudinale de la poutrelle 1.In Figures 1 and 2, there is shown the preferred arrangement of the legs in pairs whose anchored parts are in the same plane transverse to the beam. As a variant, FIG. 3 shows that the legs can be arranged otherwise, for example alternately on one side and the other of the longitudinal median plane along the longitudinal extension of the beam 1.

Selon les figures 1 et 2 les pattes 2 appartenant à une même paire sont reliées entre elles par les barrettes 7. Cette disposition a pour avantage d'assurer un correct positionnement relatif dos 2 paires et do permettre leur mise en place par appui des barrettes 7 sur les fils de précontrainte 8 comme exposé plus en détail au sujet des figures 4 à 10.According to Figures 1 and 2 the legs 2 belonging to the same pair are interconnected by the bars 7. This arrangement has the advantage of ensuring correct relative positioning on the back of 2 pairs and of allowing them to be put in place by pressing the bars 7 on the prestressing wires 8 as explained in more detail with regard to FIGS. 4 to 10.

Les pattes étant initialement repliées à 90°, et étant coulées à l'envers, la mise en place consiste à enfoncer dans le béton frais los talons dos pattes 2 ot leurs barrot- tes 7 associécs jusqu'à co que les barrottos 7 reposent sur les fils 8, les branches reliées dos pattes 2 reposant sur lo béton frais ot étant calées latéralement contre les fils 8 par leurs angles 9.The legs being initially folded at 90 °, and being cast upside down, the installation consists of pressing in fresh concrete the heels back legs 2 ot their bars 7 associated until co that the barrottos 7 rest on the wires 8, the branches connected back legs 2 resting on the fresh concrete ot being wedged laterally against the wires 8 by their angles 9.

Solon une disposition do l'invention, les clous 4 sont insérés dans les fourreaux 3 à la fabrication des insorts et les poutrolles sont ainsi livrées avec pattes et clous de sorte qu'il n'y a pas d'approvisionnement à faire sur le chantier pour la mise en place des lattes 5.According to a provision of the invention, the nails 4 are inserted into the sleeves 3 in the manufacture of the inserts and the beams are thus delivered with lugs and nails so that there is no supply to be made on site for placing the slats 5.

Los pattes étant initialement repliées à 90°, le long de la sous-face dos poutrellos 1, l'encombrement des poutrelles n'est pas augmenté, leur stockage et leur transport ne posent aucun problème.Los legs being initially folded at 90 °, along the underside back of the beams 1, the size of the beams is not increased, their storage and transport are no problem.

Les figures 4 à 10 illustrent diverses variantes de réalisation de l'insort en forme de U.Figures 4 to 10 illustrate various alternative embodiments of the U-shaped insert.

Selon les figures 4 et 5 l'insert est formé de deux pattes 2 reliées par une barrette 7.According to FIGS. 4 and 5, the insert is formed by two legs 2 connected by a bar 7.

Solon les figures 6 à 10 l'insert est d'une pièce découpée dans de la tôle plate, la barrette 7 étant unitaire avec les pattos 2.Solon Figures 6 to 10 the insert is of a piece cut from flat sheet metal, the bar 7 being unitary with the pattos 2.

Lo calage latéral par rapport aux fils 8 est obtenu par des échancrures 10 ou crans, figures 4, 6 et 10, par des dents 11, figures 7 et 8, par les deux figure 9 ; l'échancrure 10 de la figure 10 est plus longue et coopère avec deux fils 8 superposés.Lo lateral setting relative to the son 8 is obtained by notches 10 or notches, Figures 4, 6 and 10, by teeth 11, Figures 7 and 8, by both Figure 9; the notch 10 in FIG. 10 is longer and cooperates with two superimposed wires 8.

Pour l'ancrage des pattes, on a prévu figures 4 et 5 des lumières 12.For anchoring the legs, provision has been made in FIGS. 4 and 5 for lights 12.

Les parties débordantes des pattes 2 sont de préférence plus rigides que la zone de pliures, Dans ce but, on a prévu, figure 4, de replier les.pattes 2 autour du clou 4 de façon à en doubler l'épaisseur sur la zone hors béton. Figures 5, 7 et 8, c'est la zono de pliure qui est affaiblie, soit par les lumièros 12 (figures 5 et 7) soit par saignées 13 (figure 8). Selon les figures 6 et 9, on a prévu de norvuror los pattos en 14, la barrette 7 pouvant êtro, ollo aussi, nervurée.The protruding parts of the legs 2 are preferably more rigid than the folded area. For this purpose, provision has been made, in FIG. 4, to fold the legs 2 around the nail 4 so as to double the thickness thereof over the area outside. concrete. Figures 5, 7 and 8, it is the fold zone which is weakened, either by the lumièros 12 (figures 5 and 7) or by grooves 13 (figure 8). According to Figures 6 and 9, there is provided norvuror los pattos at 14, the bar 7 can be narrow, also ollo, ribbed.

Selon les figures 4, 5, 6, 8, 9, la mise en place du clou est obtenu par enroulement de la patte 2. Selon les figuros 7 et 10, on a embouti dos lamolles 15 définies par des mignées pratiquées dans les pattos.According to FIGS. 4, 5, 6, 8, 9, the insertion of the nail is obtained by winding the tab 2. According to the figuros 7 and 10, stamped back lamolles 15 defined by lines practiced in pattos.

Dans le cas do la figure 10, los pattos so terminent par dos languottes 16 inclinées qui maintiennent l'extrémité dos pattos à faible distance do la poutrelle co qui facilite d'un tournevis un marteau pour les déplior sur chantier.In the case of Figure 10, los pattos so end with angled back tongues 16 which keep the back pattos end at a short distance from the joist co which facilitates a hammer for a screwdriver for unfolding on site.

La distance d'une patte au plan médian longitudinal, et par suite la largeur do l'espace libre entre les pattos d'un côté et collos do l'autro côté do la poutro sera déterminée on fonction do la largeur dos lattes à mettre en place. En pratique cet espace libre sera do 4 à 6 cm environ.The distance from one leg to the longitudinal median plane, and therefore the width of the free space between the legs on one side and the collos on the other side of the beam, will be determined according to the width of the slats to be placed. square. In practice this free space will be approximately 4 to 6 cm.

La distance entro pattes ou paires de pattes selon la direction longitudinale dos poutrelles dépendra du calepinage. Elle sera en pratique de l'ordre de 0,5 à 1 m, do préférence au voisinago do 0,60 m.The distance between legs or pairs of legs in the longitudinal direction of the beams will depend on the layout. It will in practice be of the order of 0.5 to 1 m, preferably in the vicinity of 0.60 m.
