Abstract

Prefabricated platform constituted by a section (1), each end of the section carrying a support (3) comprising a vertical member to which are fixed two suspension hooks (2) intended to be positioned and fitted around a horizontal tie-bar (8) of a construction. The vertical member is pierced through by at least one opening (4) having its horizontal axis located in the same vertical plane as the longitudinal axis as one of the suspension hooks (2). The abovementioned opening (4) permits the passage of the upper portion of a locking device (6) attached to the lower portion of the support (3) so as to be able to pivot in a vertical plane and so that when the corresponding suspension hook (2) is positioned over a horizontal tie-bar (8), the locking device (6) interacts with the lateral surface of the tie-bar (8) and bears against the latter. <IMAGE>

Description

La présente invention concerne un procédé de liaison d'un plancher préfabriqué avec une traverse horizontale d'une construction, le plancher étant constitué d'un profilé dont chaque extrémité porte un support comprenant un membre vertical sur lequel sont fixés deux crochets de suspension destinés à se placer et emboîter la traverse horizontale d'une construction, ledit membre vertical étant percé d'au moins une ouverture ayant son axe horizontal situé dans le même plan vertical que l'axe longitudinal d'un des crochets de suspension, l'ouverture précitée permettant le passage de la partie supérieure d'un verrou attaché à la partie inférieure du support de manière à pouvoir pivoter dans un plan vertical et de manière que, lorsque le crochet de suspension correspondant se trouve placé sur la traverse horizontale, le verrou coopère avec la surface latérale de la traverse.The present invention relates to a method of connecting a prefabricated floor with a horizontal cross member of a construction, the floor consisting of a profile, each end of which carries a support comprising a vertical member on which are fixed two suspension hooks intended for place and fit the horizontal crosspiece of a construction, said vertical member being pierced with at least one opening having its horizontal axis located in the same vertical plane as the longitudinal axis of one of the suspension hooks, the aforementioned opening allowing the passage of the upper part of a lock attached to the lower part of the support so as to be able to pivot in a vertical plane and so that, when the corresponding suspension hook is placed on the horizontal cross-member, the lock cooperates with the lateral surface of the crosspiece.

L'invention concerne également un plancher préfabriqué pour la mise en oeuvre du procédé.The invention also relates to a prefabricated floor for implementing the method.

Un plancher métallique a sur un plancher en bois traditionnel l'avantage d'être plus léger et de moins se dégrader. Un plancher métallique est habituellement constitué d'une tôle métallique pliée ou/et emboutie pour former un caisson résistant. Chaque plancher métallique est muni d'attaches pour la suspension et la fixation sur des traverses horizontales d'une construction, par exemple un échafaudage ou une ossature.A metal floor has the advantage over a traditional wooden floor of being lighter and less degrading. A metal floor is usually made of a folded metal sheet and / or stamped to form a resistant box. Each metal floor is provided with fasteners for suspension and fixing on horizontal sleepers of a construction, for example a scaffolding or a framework.

Les attaches sont habituellement des pattes destinées à être posées sur une traverse horizontale afin de suspendre ainsi le plancher. Ce mode d'attache ne s'oppose pas au soulèvement (par exemple par le vent) ni au jeu qui sont préjudiciables à la stabilité du plancher et à la sécurité du personnel de chantier, des personnes et des biens. Ce mode d'attache n'assure donc pas un verrouillage sur la traverse. Un déséquilibrage de la charge sur le plancher peut dès lors produire un mouvement du plancher et constituer un danger pour le personnel de chantier.The fasteners are usually legs intended to be placed on a horizontal crosspiece in order to thus suspend the floor. This method of attachment is not opposed to lifting (for example by the wind) or play which are detrimental to the stability of the floor and the safety of site personnel, people and property. This method of attachment therefore does not ensure locking on the cross-member. An imbalance of the load on the floor can therefore produce a movement of the floor and constitute a danger for the site personnel.

Par FR-A-2485598 est connue une plate-forme pour échafaudages tubulaires métalliques qui comprend à ses extrémités au moins un anneau de forme triangulaire qui est enfilé à travers un trou pratiqué dans une aile de profilés en U dont sont équipées les extrémités de la plate-forme. L'anneau précité constitue certes un moyen de retenue pour la plate-forme mais le maintien de la plate-forme sur une traverse horizontale se fait avec un jeu de sorte que l'anneau ne s'appuie pas contre la surface de la traverse et n'assure pas un serrage de la plate-forme sur la traverse. De plus, l'anneau en question ne réalise pas automatiquement le verrouillage pendant l'opération d'accrochage même et la fixation d'une plate-forme sur une traverse nécessite donc deux opérations successives : une opération d'accrochage et une opération de verrouillage.By FR-A-2485598 is known a platform for metallic tubular scaffolding which comprises at its ends at least one ring of triangular shape which is threaded through a hole made in a wing of U-shaped profiles with which the ends are fitted. of the platform. The aforementioned ring certainly constitutes a retaining means for the platform but the maintenance of the platform on a horizontal cross-member is done with a clearance so that the ring does not bear against the surface of the cross-member and does not ensure a clamping of the platform on the crosspiece. In addition, the ring in question does not automatically carry out the locking during the same hooking operation and the fixing of a platform on a cross member therefore requires two successive operations: a hooking operation and a locking operation .

L'invention vise à remédier aux inconvénients de la technique connue. Elle propose un plancher préfabriqué ayant des dispositifs d'attache qui assurent non seulement un verrouillage et un déverrouillage aisés, mais également un verrouillage fiable et automatique, propre à garantir une parfaite stabilité d'assise au plancher.The invention aims to remedy the drawbacks of the known technique. It offers a prefabricated floor with fastening devices which not only ensure easy locking and unlocking, but also reliable and automatic locking, capable of guaranteeing perfect seating stability on the floor.

Cet objectif est atteint selon l'invention par un procédé de liaison d'un plancher préfabriqué avec une traverse horizontale d'une construction, ledit plancher étant constitué d'un profilé dont chaque extrémité porte un support comprenant un membre vertical sur lequel sont fixés deux crochets de suspension destinés à se placer et emboîter la traverse horizontale d'une construction, ledit membre vertical étant percé d'au moins une ouverture ayant son axe horizontal situé dans le même plan vertical que l'axe longitudinal d'un des crochets de suspension, l'ouverture précitée permettant le passage de la partie supérieure d'un verrou attaché à la partie inférieure du support de manière à pouvoir pivoter dans un plan vertical et de manière que, lorsque le crochet de suspension correspondant se trouve placé sur la traverse horizontale, le verrou coopère avec la surface latérale de la traverse, ledit procédé étant caractérisé en ce qu'on accroche le verrou par son extrémité inférieure à une aile horizontale du support de manière qu'il puisse pivoter dans un plan vertical et s'appuyer contre la surface latérale inférieure de la traverse horizontale.This objective is achieved according to the invention by a method of connecting a prefabricated floor with a horizontal cross member of a construction, said floor consisting of a profile, each end of which carries a support comprising a vertical member to which two suspension hooks intended to be placed and to fit the horizontal crosspiece of a construction, said vertical member being pierced by at least one opening having its horizontal axis situated in the same vertical plane as the longitudinal axis of one of the suspension hooks , the aforementioned opening allowing the passage of the upper part of a lock attached to the lower part of the support so as to be able to pivot in a vertical plane and so that, when the suspension hook corresponding is placed on the horizontal cross member, the lock cooperates with the lateral surface of the cross member, said method being characterized in that the lock is hooked by its lower end to a horizontal wing of the support so that it can pivot in a vertical plane and lean against the lower lateral surface of the horizontal crosspiece.

Dans un mode de réalisation particulier, l'extrémité inférieure du verrou traverse l'aile horizontale du support dans une ouverture.In a particular embodiment, the lower end of the bolt crosses the horizontal wing of the support in an opening.

Avantageusement, l'extrémité inférieure du verrou est accrochée au support à l'aide d'une tête constituée d'une vis.Advantageously, the lower end of the lock is hooked to the support using a head consisting of a screw.

Conformément à un second aspect de l'invention, pour la mise en oeuvre du procédé défini ci-dessus il est proposé un plancher préfabriqué constitué d'un profilé dont chaque extrémité porte un support comprenant un membre vertical sur lequel sont fixés deux crochets de suspension destinés à emboîter une traverse horizontale d'une construction, ledit membre vertical étant percé d'au moins une ouverture ayant son axe horizontal situé dans le même plan vertical que l'axe longitudinal d'un crochet de suspension, l'ouverture précitée permettant le passage de la partie supérieure d'un verrou attaché à la partie inférieure du support de manière à pouvoir pivoter dans un plan vertical et de manière que, lorsque le crochet de suspension correspondant se trouve placé sur une traverse horizontale, le verrou coopère avec la surface latérale inférieure de la traverse, ledit plancher étant caractérisé en ce que le verrou est accroché par son extrémité inférieure à une aile horizontale du support de manière à pouvoir pivoter dans un plan vertical et s'appuyer contre la surface latérale inférieure de la traverse horizontale.In accordance with a second aspect of the invention, for the implementation of the method defined above, a prefabricated floor is proposed, consisting of a profile, each end of which carries a support comprising a vertical member on which two suspension hooks are fixed. intended to fit a horizontal cross member of a construction, said vertical member being pierced with at least one opening having its horizontal axis situated in the same vertical plane as the longitudinal axis of a suspension hook, the aforementioned opening allowing the passage of the upper part of a lock attached to the lower part of the support so as to be able to pivot in a vertical plane and so that, when the corresponding suspension hook is placed on a horizontal cross-member, the lock cooperates with the surface lower lateral side of the cross member, said floor being characterized in that the latch is hooked by its lower end e to a horizontal wing of the support so as to be able to pivot in a vertical plane and to bear against the lower lateral surface of the horizontal cross-member.

Grâce à l'invention, le verrou assure toujours le meilleur contact avec la traverse, quelle que soit la position relative de ces deux pièces, et réalise, en une seule opération, à la fois l'accrochage et le verrouillage d'un plancher sur une traverse horizontale. Ce procédé empêche ainsi tout basculement du plancher sous le poids d'une personne marchant sur le plancher et empêche également toute possibilité de soulèvement du plancher par le vent, ce qui assure une excellente stabilité de fixation de la traverse.Thanks to the invention, the lock always ensures the best contact with the crosspiece, whatever the relative position of these two parts, and achieves, in a single operation, both the attachment and the locking of a floor on a horizontal crosspiece. This method thus prevents any tilting of the floor under the weight of a person walking on the floor and also prevents any possibility of lifting of the floor by the wind, which ensures excellent fixing stability of the crosspiece.

De plus, grâce à leur accrochage sous l'aile horizontale du support, les verrous sont entièrement escamotables à l'intérieur du profilé, et cela permet un entreposage aisé et compact des planchers préfabriqués munis de leurs crochets de suspension.In addition, thanks to their hooking under the horizontal wing of the support, the latches are fully retractable inside the profile, and this allows easy and compact storage of prefabricated floors provided with their suspension hooks.

L'invention est exposée dans ce qui suit à l'aide des dessins joints.The invention is set out in the following with the aid of the accompanying drawings.

La figure 1 est une vue en élévation d'un mode d'exécution exemplaire d'un plancher selon l'invention.Figure 1 is an elevational view of an exemplary embodiment of a floor according to the invention.

La figure 2 est une vue en plan du plancher de la figure 1.Figure 2 is a plan view of the floor of Figure 1.

La figure 3 est une coupe transversale suivant la ligne III-III de la figure 2.FIG. 3 is a cross section along line III-III of FIG. 2.

La figure 4 est une vue en coupe, à échelle agrandie, du dispositif d'accrochage et de verrouillage selon l'invention.Figure 4 is a sectional view, on an enlarged scale, of the attachment and locking device according to the invention.

La figure 5 est une vue semblable à celle de la figure 4 mais montrant le dispositif de verrouillage en position déverrouillée.Figure 5 is a view similar to that of Figure 4 but showing the locking device in the unlocked position.

Se reportant aux figures 1 à 3, on voit représenté un plancher exemplaire constitué d'un profilé métallique 1 ayant une forme générale en U. Le profilé 1 est par exemple en acier galvanisé. La face principale 11 du profilé présente des bossages parallèles 12 servant de répartisseurs de charge. Dans la surface des bossages 12 sont avantageusement formés des reliefs antidérapants 14 en nombre quelconque.Referring to Figures 1 to 3, there is shown an exemplary floor consisting of a metal profile 1 having a general U shape. The profile 1 is for example made of galvanized steel. The main face 11 of the profile has parallel bosses 12 serving as load distributors. In the surface of the bosses 12 are advantageously formed non-slip reliefs 14 in any number.

Aux extrémités latérales du profilé 1 sont fixés des crochets de suspension 2 destinés à emboîter deux traverses horizontales d'une construction, par exemple un échafaudage, de manière à y suspendre le plancher 1. Suivant la longueur du profilé 1, un ou plusieurs raidisseurs (non représentés) sont utilement prévus à l'intérieur du profilé afin d'assurer la raideur voulue alliée à la légèreté souhaitée de l'ensemble. Ils sont chacun constitué par un profilé soudé entre les extrémités des ailes inférieures du profilé 1.At the lateral ends of the profile 1 are fixed suspension hooks 2 intended to fit two horizontal crosspieces of a construction, for example a scaffolding, so as to suspend the floor 1. Depending on the length of the profile 1, one or more stiffeners ( not shown) are usefully provided inside the profile in order to ensure the desired stiffness combined with the desired lightness of the assembly. They each consist of a section welded between the ends of the lower wings of section 1.

La figure 4 représente à échelle agrandie une extrémité du plancher 1 et elle montre en particulier un dispositif d'accrochage et de verrouillage pour la fixation du plancher sur une traverse horizontale d'une construction. On observe que les crochets 2 se trouvent soudés sur un support 3, constitué par exemple d'un fer en U, fixé à l'extrémité et à l'intérieur du profilé 1. L'âme du fer 3, c'est-à-dire le membre vertical du support, est percée d'une ouverture 4 ayant son axe horizontal situé dans le même plan vertical que l'axe longitudinal d'un des crochets de suspension 2. Dans l'ouverture 4 passe la partie supérieure d'un verrou pivotant 6 accroché à la partie inférieure du support 3 de manière à pouvoir pivoter dans un plan vertical. Dans l'exemple illustré, l'extrémité inférieure du verrou 6 traverse une ouverture 5 ménagée dans l'aile inférieure du fer 3 et elle est munie d'une tête d'accrochage 7 constituée, par exemple, par une vis autotaraudeuse à tête cylindrique. La tête d'accrochage 7 assure la suspension du verrou 6 tout en permettant le pivotement de celui-ci autour d'un axe horizontal.Figure 4 shows on an enlarged scale one end of the floor 1 and it shows in particular a hooking and locking device for fixing the floor on a horizontal crosspiece of a construction. It is observed that the hooks 2 are welded to a support 3, consisting for example of a U-shaped iron, fixed at the end and inside the profile 1. The core of the iron 3, that is to say -to say the vertical member of the support, is pierced with an opening 4 having its horizontal axis located in the same vertical plane as the longitudinal axis of one of the suspension hooks 2. In the opening 4 passes the upper part of a pivoting lock 6 attached to the lower part of the support 3 so as to be able to pivot in a vertical plane. In the example illustrated, the lower end of the bolt 6 passes through an opening 5 formed in the lower wing of the iron 3 and it is provided with a hooking head 7 constituted, for example, by a self-tapping screw with a cylindrical head . The attachment head 7 ensures the suspension of the latch 6 while allowing the pivoting thereof around a horizontal axis.

Un verrou 6 est prévu à chaque extrémité du plancher 1 comme le montre la figure 1. Il est évident que l'on pourrait prévoir deux verrous à chaque extrémité, bien qu'en pratique un verrou à chaque extrémité suffise pour assurer la sécurité de la fixation.A lock 6 is provided at each end of the floor 1 as shown in Figure 1. It is obvious that one could provide two locks at each end, although in practice a lock at each end is sufficient to ensure the security of the fixation.

La mise en place du plancher selon l'invention sur une traverse horizontale, ainsi que l'accrochage et le verrouillage sur celle-ci se font en une seule opération par le simple emboîtement des crochets de suspension 2 et de la traverse, et le verrouillage sur la traverse se fait automatiquement. Lorsque l'on pose un crochet de suspension 2 muni d'un verrou 6 sur une traverse horizontale, celle-ci soulève le verrou 6 et le fait pivoter dans le sens contraire à celui du mouvement des aiguilles d'une montre. Lorsque le verrou 6 se trouve amené dans une position telle que montrée dans la figure 5 par exemple, c'est-à-dire une position qui permet à la traverse 8 de s'engager dans l'ouverture du crochet de suspension 2, celui-ci vient reposer sur et emboîter la traverse 8 (figure 4) en basculant et en s'appuyant contre la surface de la traverse. Au moment où la traverse et le crochet de suspension se trouvent complètement emboîtés (figure 4), le verrou 6 bascule et sa face extérieure 60 vient appuyer contre la traverse 8 et verrouille celle-ci dans l'ouverture du crochet de suspension 2. Le profil incurvé du verrou 6 assure ainsi toujours un emboîtement et une fixation sans jeu qui est garante d'une parfaite stabilité du plancher suspendu et est par conséquent garante d'une totale sécurité pour le personnel de chantier, ainsi que pour les personnes et les biens, par exemple en cas de tempête.The installation of the floor according to the invention on a horizontal cross member, as well as the hooking and locking on it is done in a single operation by the simple interlocking of the suspension hooks 2 and the cross member, and the locking on the crosspiece is done automatically. When a suspension hook 2 fitted with a lock 6 is placed on a horizontal crosspiece, the latter raises the lock 6 and makes it rotate in the opposite direction to that of the movement of the needles of a watch. When the lock 6 is brought into a position as shown in Figure 5 for example, that is to say a position which allows the cross member 8 to engage in the opening of the suspension hook 2, it comes to rest on and fit the cross member 8 (Figure 4) by tilting and pressing against the surface of the cross member. When the cross member and the suspension hook are completely nested (Figure 4), the latch 6 rocks and its outer face 60 comes to press against the cross member 8 and locks it in the opening of the suspension hook 2. curved profile of the lock 6 thus always ensures an interlocking and fixing without play which guarantees perfect stability of the suspended floor and therefore guarantees total security for site personnel, as well as for people and goods , for example in the event of a storm.

Le déverrouillage d'une fixation se fait également d'une façon très simple. Une pression sur le talon 62 du verrou 6 suffit pour faire pivoter celui-ci dans le sens contraire à celui du mouvement des aiguilles d'une montre et le dégager de la traverse.Unlocking a binding is also very simple. A pressure on the heel 62 of the latch 6 is sufficient to rotate the latter in the opposite direction to that of the movement of the needles of a watch and to release it from the cross-member.

Le mode d'exécution exemplaire du dispositif de verrouillage selon l'invention a également pour avantage de permettre le remplacement aisé du verrou 6. En effet, comme celui-ci se trouve accroché au support 3 par une tête formée d'une vis 7, il suffit de dévisser la tête 7 pour retirer le verrou 6 et de visser la tête 7 dans le nouveau verrou.The exemplary embodiment of the locking device according to the invention also has the advantage of allowing easy replacement of the lock 6. In fact, since the latter is attached to the support 3 by a head formed by a screw 7, simply unscrew the head 7 to remove the lock 6 and screw the head 7 into the new lock.

Suivant un aspect avantageux de l'invention, le profilé 1 et les verrous 6 sont réalisés de telle manière que les ailes latérales 15 et 16 du profilé (voir figure 3) protègent les verrous 6 lorsque ceux-ci se trouvent dans leur position relevée (position de déverrouillage). Se reportant à la figure 5 par exemple, on voit en effet que le talon 62 du verrou 6 ne dépasse pas l'aile inférieure 17 du profilé lorsque le verrou est relevé. Le fait que les verrous 6 d'un plancher sont ainsi escamotables à l'intérieur du profilé 1 permet de poser les planchers par terre, sans risque de les détériorer, et cela facilite l'entreposage des planchers selon l'invention.According to an advantageous aspect of the invention, the profile 1 and the latches 6 are produced in such a way that the lateral wings 15 and 16 of the profile (see figure 3) protect the latches 6 when they are in their raised position (unlocking position). Referring to Figure 5 for example, it can be seen that the heel 62 of the latch 6 does not exceed the lower wing 17 of the profile when the latch is raised. The fact that the bolts 6 of a floor are thus retractable inside the profile 1 makes it possible to lay the floors on the ground, without risk of damaging them, and this facilitates the storage of the floors according to the invention.

Comme décrit précédemment, la face principale 11 du profilé 1 présente des bossages parallèles 12 (figures 1 et 2). Ces bossages 12 délimitent entre eux des canaux 13 qui facilitent l'écoulement des eaux de pluie, en particulier au travers de trous 18 situés dans les canaux 13. De cette manière, les eaux de pluie ne stagnent pas sur la surface du plancher et on évite ainsi la formation de plaques de verglas par temps de gel, ce qui accroît la sécurité pour le personnel de chantier.As described above, the main face 11 of the profile 1 has parallel bosses 12 (Figures 1 and 2). These bosses 12 define between them channels 13 which facilitate the flow of rainwater, in particular through holes 18 located in the channels 13. In this way, rainwater does not stagnate on the surface of the floor and This prevents ice sheets from forming in freezing weather, which increases safety for site personnel.

Le mode de réalisation de l'invention décrit dans ce qui précède est un exemple donné à titre illustratif et l'invention n'est nullement limitée à cet exemple. Toute modification, toute variante et tout agencement équivalent doivent être considérés comme compris dans le cadre de l'invention telle que décrite dans les revendications.The embodiment of the invention described in the foregoing is an example given by way of illustration and the invention is in no way limited to this example. Any modification, any variant and any equivalent arrangement must be considered to be within the scope of the invention as described in the claims.
