Description

La présente invention concerne un plancher préfabriqué pourvu de dispositifs d'attache de sécurité pour per­mettre la fixation sur des traverses horizontales d'un échafaudage ou d'une construction similaire avec une stabilité de fixation excellente.The present invention relates to a prefabricated floor provided with safety fastening devices to allow fixing on horizontal crosspieces of scaffolding or a similar construction with excellent fixing stability.

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. 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.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. 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 site personnel.

L'invention vise à remédier aux inconvénients de la technique connue. Elle a pour but de procurer 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. Its purpose is to provide a prefabricated floor having fastening devices which not only ensure easy locking and unlocking, but also locking. reliable and automatic, capable of guaranteeing perfect seat stability on the floor.

Cet objectif est atteint grâce à l'invention par un plancher constitué d'un profilé, chaque extrémité du profilé étant fermée par 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 permet 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 et appuie contre celle-ci.This objective is achieved thanks to the invention by a floor consisting of a profile, each end of the profile being closed by a support comprising a vertical member on which are fixed two suspension hooks intended to fit a horizontal crosspiece 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 allows 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 lower lateral surface of the cross member and presses against it.

Suivant un autre aspect de l'invention, la partie su­périeure du verrou est profilée de manière à toujours assurer le meilleur contact entre le verrou et la tra­verse, quelle que soit la position relative de ces deux pièces.According to another aspect of the invention, the upper part of the lock is profiled so as to always ensure the best contact between the lock and the crosspiece, regardless of the relative position of these two parts.

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.
  • Figure 1 is an elevational view of an exemplary embodiment of a floor according to the invention.
  • Figure 2 is a plan view of the floor of Figure 1.
  • Figure 3 is a cross section along line III-III of Figure 2.
  • Figure 4 is a sectional view, on an enlarged scale, of the attachment and locking device according to the invention.
  • 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 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 hooked 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 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 lock 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 establishment of the floor according to the invention on a horizontal cross member, as well as the hooking and locking on it are 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 hands 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 toggles and its outer face 60 presses against the cross member 8 and locks it in the opening of the suspension hook 2. The curved profile of the bolt 6 thus always ensures an interlocking and a 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 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, as the latter is attached to the support 3 by a head formed by a screw 7, just 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 fi­ gure 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 fi gure 3) protect the latches 6 when they are in their raised position (unlocking position). Referring to Figure 5 for example, it is 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 delimit 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.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.
