Abstract
Description
La présente invention se rapporte au domaine technique des échafaudages.The present invention relates to the technical field of scaffolding.
Par « échafaudage », on désigne ici toute construction ou bâti provisoire, fixe ou mobile, facilitant l'accès aux ouvrages et la réalisation de travaux.By "scaffolding" is meant here any temporary building or structure, fixed or movable, facilitating access to works and carrying out work.
Sont notamment concernés par la présente invention :
- les échafaudages de pied, c'est-à-dire les échafaudages sur plans verticaux destinés aux travaux sur façades et parties en élévation ;
- les échafaudages rapides métalliques, en éléments modulaires, parfois appelés échafaudages tubulaires ;
- les échafaudages de plafond ou sur plans horizontaux, c'est-à-dire les échafaudages tubulaires légers, en général mobiles (roulants) et les échafaudages sur tréteaux ;
- les échafaudages en bascule portés par des traverses étrésillonnés contre des encadrements de baies ;
- les échafaudages en éventail portés par des potences ou pointiers inclinés reposant sur les appuis des baies et immobilisés par des entretoises ou des étrésillons.
- foot scaffolding, ie scaffolding on vertical planes for work on facades and elevations;
- metal rapid scaffolding, in modular elements, sometimes called tubular scaffolds;
- ceiling scaffolding or horizontal planes, ie light tubular scaffoldings, generally mobile (rolling) and scaffolding on trestles;
- the scaffolding in tilts carried by cross-braced braces against frames of bays;
- Fan scaffolding carried by brackets or inclined points resting on the supports of the bays and immobilized by spacers or braces.
L'invention trouve une application particulièrement avantageuse pour les échafaudages rapides.The invention finds a particularly advantageous application for rapid scaffolding.
Dans un montage conventionnel, de conception assez ancienne, un échafaudage comprend des montants verticaux, autrefois dénommés perches, écoperches, pointiers, fixés ou callés au sol sur des semelles ou patins, ces montants étant espacés dans le sens de la longueur de l'échafaudage par des longerons horizontaux (filières, longrines, ou tendières). Transversalement, des traverses ou boulins portent des planchers. Les éléments sont assemblés par exemple par des brêlages de cordes ou de chaînes. L'ensemble est rigidifié par des entretoises en croix de Saint André et pourvu de lisses ou garde corps.In a conventional assembly, of rather old design, a scaffold comprises uprights, formerly called poles, scallops, pins, fixed or grounded on soles or pads, these amounts being spaced in the direction of the length of the scaffolding horizontal spars (dies, longrins, or tendons). Transversally, sleepers or boulins carry floors. The elements are assembled for example by lashings of ropes or chains. The whole is stiffened by cross struts of St. Andrew and provided with smooth or railing.
Ainsi, par exemple, un échafaudage classique comprend deux échelles à montants et échelons tubulaires et de section ronde, les échelles étant reliées l'une à l'autre verticalement par au moins deux barres diagonales fixées en croix et de chaque côté de l'échafaudage, les barres étant fixées par leurs extrémités à des échelons d'échelle.Thus, for example, a conventional scaffold comprises two ladders with stiles and tubular steps and of round section, the ladders being connected to each other vertically by at least two diagonal bars fixed in cross and on each side of the scaffolding , the bars being fixed at their ends to ladder steps.
Conventionnellement, l'échafaudage comporte des traverses telles que filières horizontales, tendières, boulins, membrures de maniement, support de plateforme, entretoises diagonales de contreventement, reliés séparément aux montants ou écoperches.Conventionally, the scaffolding includes sleepers such as horizontal dies, tendons, balls, handling members, platform support, diagonal bracing struts, separately connected to the uprights or pegs.
Pour réaliser un échafaudage, il est ainsi nécessaire d'attacher à des montants, des barres d'appui, des jambes de forces,des extrémités d'éléments de liaison, de type entretoises, pour renforcer, stabiliser, rigidifier, trianguler la construction de sorte à empêcher son affaissement.To realize a scaffolding, it is thus necessary to attach to uprights, support bars, legs of forces, ends of connecting elements, type spacers, to strengthen, stabilize, stiffen, triangulate the construction of so as to prevent its subsidence.
La fixation des entretoises à leur support n'ayant qu'un caractère temporaire, les modes de fixation et de verrouillage adoptés doivent permettre d'exécuter rapidement et facilement la mise en place et le démontage de ces entretoises.Since the fixing of the spacers to their support is only temporary, the fixing and locking methods adopted must make it possible to quickly and easily carry out the installation and dismantling of these spacers.
On connaît, dans l'art antérieur, plusieurs types de moyens de fixation d'haubans avec les plans de la structure d'un échafaudage.Several types of guy fixing means are known in the prior art with the plans of the structure of a scaffold.
Par exemple, on connaît le montage par clavetage. Selon une autre conception, un collier de section légèrement supérieure à la section d'un montant, coulisse au long de ce montant, lequel montant présente une pluralité de trous répartis au long de son axe longitudinal au travers desquels est engagée une goupille qui limite au moins dans un sens la translation du collier.For example, we know the mounting by keying. According to another design, a collar section slightly greater than the section of a post, slides along this amount, which amount has a plurality of holes distributed along its longitudinal axis through which is engaged a pin which limits to the less in a sense the translation of the collar.
On connaît également un dispositif de fixation qui comprend deux brides complémentaires formant collier. L'une des brides, dite fixe, étant solidarisée à la pièce, par exemple, à l'extrémité d'une traverse et l'autre bride, dite mobile, est associée à la bride fixe par un moyen de manoeuvre qui, par rapprochement des brides entre elles, permet de resserrer le collier sur le montant et de s'opposer à la translation de la pièce rapportée. Habituellement, le moyen de manoeuvre consiste en une pluralité de boulons qui traversent de part en part les brides. Ce type de dispositif permet de fixer la pièce rapportée en tous points du montant mais comporte un inconvénient majeur qui est le temps nécessaire au serrage et desserrage des brides. Egalement, il n'est pas rare que l'individu chargé du serrage de ces brides oublie accidentellement de serrer au moins certains des boulons.Also known is a fixing device which comprises two complementary flanges forming a collar. One of the flanges, said fixed, being secured to the piece, for example, at the end of a cross and the other flange, said mobile, is associated with the fixed flange by a maneuvering means which, by approximation flanges between them, allows to tighten the collar on the amount and to oppose the translation of the insert. Usually, the operating means consists of a plurality of bolts which pass right through the flanges. This type of device allows to fix the insert at any point of the amount but has a major drawback which is the time required to tighten and loosen the flanges. Also, it is not uncommon for the individual responsible for tightening these flanges to accidentally forget to tighten at least some of the bolts.
On connaît également des articulations de type « semi auto ». Ces articulations sont composées de haubans dont les extrémités aplaties sont pourvues d'un axe serti de caoutchouc servant d'axe de rotation à une mâchoire en tôle d'acier, la rotation de cette mâchoire englobant les profils du plan d'échafaudage."Semi auto" type joints are also known. These joints are composed of stays whose flattened ends are provided with a crimped axis of rubber serving as an axis of rotation to a sheet steel jaw, the rotation of this jaw encompassing the profiles of the scaffold plane.
Les moyens connus présentés ci-dessus comportent de nombreux inconvénients.The known means presented above have many disadvantages.
Les fixations par vis et écrou sont perdables.Les articulations de type « semi auto » nécessitent un outillage spécifique. Lorsque l'assemblage met en oeuvre un coin métallique enfoncé au maillet, le montage et le démontage ont assez long et difficile.Fasteners by screw and nut are lost. The joints of type "semi auto" require specific tools. When the assembly implements a metal wedge pressed to the mallet, the assembly and disassembly have long enough and difficult.
Actuellement, les barres diagonales de liaison transversale des échelles d'échafaudage sont fixées pour la plupart au moyen de crochets à mâchoire mobile en prise sur les échelons d'échelle. L'assemblage de la diagonale est plus complexe que celui d'un longeron ou d'une traverse, la diagonale pouvant prendre un angle d'inclinaison variable par rapport à l'horizontale, cet angle étant fonction des dimensions de la maille rectangulaire définie par la longueur des longerons (typiquement de 3 m, 2.5m, 2m, ou 1.5 m) et par la distance verticale entre deux longerons superposés (typiquement 2 mètres).Currently, the diagonal transverse link bars of the scaffold ladders are mostly fixed by means of movable jaw hooks engaged on the ladder rungs. The assembly of the diagonal is more complex than that of a spar or a cross, the diagonal can take a variable angle of inclination relative to the horizontal, this angle being a function of the dimensions of the rectangular mesh defined by the length of the spars (typically 3 m, 2.5 m, 2 m, or 1.5 m) and the vertical distance between two superimposed spars (typically 2 meters).
La présente invention vise à fournir un dispositif de fixation d'un élément d'échafaudage, en particulier d'une lisse, d'une sous lisse ou d'une diagonale, ce dispositif, tout en conservant une configuration simple et de fabrication économique, éliminant les inconvénients précités en assurant une sûreté de blocage, avec possibilité de visualisation d'un mauvais verrouillage.The present invention aims to provide a device for fixing a scaffolding element, in particular a smooth, a sub-smooth or a diagonal, this device, while maintaining a simple configuration and economical manufacturing, eliminating the aforementioned drawbacks by providing blocking safety, with possibility of viewing a bad lock.

Dans une réalisation, la partie arrière du dispositif de fixation, lorsque vue de face, comprend une base et deux ailes rentrantes.In one embodiment, the rear part of the fixing device, when viewed from the front, comprises a base and two re-entrant wings.
Avantageusement, le dispositif de fixation est un fil métallique plié, ou, dans des réalisations moins avantageuses, moulé, formé par estampage, matriçage.Advantageously, the fixing device is a folded metal wire, or, in less advantageous embodiments, molded, formed by stamping, stamping.
Le dispositif de fixation comprend avantageusement une zone de préhension pourvue d'un manchon en élastomère, permettant une prise en mains plus agréable, même par temps froid, ou lorsque le dispositif a reçu des corps gras.The fixing device advantageously comprises a gripping zone provided with an elastomer sleeve, allowing a more pleasant handling, even in cold weather, or when the device has received fat.
Dans une réalisation, le dispositif de fixation est monté à demeure sur la première pièce et est ainsi imperdable.In one embodiment, the fixing device is permanently mounted on the first part and is thus captive.
