La présente invention concerne un système ajustable de sécurité sous forme modulable destiné à être utilisé notamment comme structure d'échafaudage à fixer en toiture, en construction, comme structure de base pour le bricolage.The present invention relates to an adjustable system safety in modular form intended for use especially as a scaffolding structure to be fixed in roof, under construction, as basic structure for DIY.

Plus particulièrement, l'invention est relative à un système de sécurité modulable pour la réalisation d'une structure d'échafaudage pour le travail en toiture et/ou en façade d'une construction. En outre, le système modulable de l'invention est aussi applicable comme structure de base pour le bricolage.More particularly, the invention relates to a modular security system for the realization of a scaffolding structure for roof work and / or in front of a building. In addition, the system modular of the invention is also applicable as basic structure for DIY.

Qu'il s'agisse des ardoisiers ou plus généralement de toute personne travaillant sur un chantier, dans le cadre des améliorations des conditions de travail, pour des raisons évidentes, il est souhaitable de pouvoir limiter les dangers d'accident de travail et de faciliter réalisation d'un échafaudage modulable de sécurité. Whether slate or more generally anyone working on a construction site, in the framework for improvements in working conditions, for obvious reasons it is desirable to be able to limit the dangers of accidents at work and facilitate the realization of modular scaffolding security.

Pour la réalisation de systèmes de protection à monter notamment sur un toit ou comme structure d'échafaudage à fixer sur un mur de construction ou sur un élément de charpente, l'homme de métier connaít l'adoption de structures modulables d'échafaudage suspendues par un point d'ancrage à la construction et prenant par ailleurs appui en au moins un autre point de la construction pour empêcher l'effet du couple de basculement s'exerçant sur ladite structure en particulier lorsqu'elle est chargée par des matériaux lourds et/ou des personnes intervenants en toiture.For the realization of protection systems with mount especially on a roof or as a structure scaffolding to be fixed on a building wall or on a structural member, the skilled person knows the adoption of modular scaffolding structures suspended by an anchor point to the construction and taking support in at least one other point of construction to prevent the torque effect from tilting exerted on said structure in especially when loaded with materials heavy and / or people working on the roof.

On a déjà proposé, en particulier dans la publication de brevet EP-A-0 930 407, une structure d'échafaudage du type porté par la construction, constituée d'une console modulable à deux branches, à savoir une première branche qui forme un montant adapté à supporter des éléments garde-corps et une seconde branche qui forme un piétement. Dans cette solution, la première branche est raccordée à la seconde branche de manière permanente suivant un angle prédéterminé et une traverse inférieure de raidissement vient en appui sur point inférieur de la construction pour empêcher l'effet du couple de basculement s'exerçant sur ladite structure, en particulier lorsqu'elle est chargée par des matériaux et/ou des intervenants en toiture.We have already proposed, in particular in the Patent publication EP-A-0 930 407, a structure of scaffolding of the type carried by the construction, consisting of a modular console with two branches, know a first branch which forms a suitable amount to support railing elements and a second branch which forms a base. In this solution, the first branch is connected to the second branch of permanently at a predetermined angle and a lower stiffening crosspiece bears on lower point of construction to prevent the effect of the tilting torque acting on said structure, especially when loaded by materials and / or roofers.

La publication FR-A-2 801 331 décrit un système ajustable de sécurité sous forme modulable suivant le préambule de la revendication 1. Plus particulièrement, ce système de sécurité comprend un premier élément de base à emboítement de forme tubulaire, et un second élément de base à emboítement de forme tubulaire complémentaire au premier élément de base. Un dispositif de raidisseur de liaison est fixé au second élément de base et adapté à raccorder le premier élément de base au second élément de base suivant un angle prédéterminé. The publication FR-A-2 801 331 describes a system adjustable security in modular form according to preamble of claim 1. More particularly, this security system includes a first element of tubular interlocking base, and a second tubular shaped base element complementary to the first basic element. A device of link stiffener is attached to the second element of base and suitable for connecting the first base element to the second base element at a predetermined angle.

Suivant cette solution connue, le premier élément modulaire est fixé par blocage de goupilles de sécurité au second élément modulaire et, pour renforcer la rigidité entre les éléments modulaires, il est prévu un renfort d'angle formant entretoise entre les éléments tubulaires servant au raidissement du système de sécurité.According to this known solution, the first element modular is fixed by locking safety pins to the second modular element and, to strengthen the rigidity between the modular elements, a corner reinforcement forming a spacer between the elements tubulars used to stiffen the security.

Ces structures sont généralement constituées de différents éléments emboítables fixés l'un à l'autre et acheminés sur le chantier.These structures generally consist of different nestable elements fixed to each other and routed to the site.

On peut toutefois reprocher à ces structures connues d'être lourdes, encombrantes et peu fiables. Pour les structures métalliques, le montage et le démontage de tels systèmes de protection prennent beaucoup de temps. En outre, les problèmes résultent également dans leur mise en oeuvre car ces structures sont de grandes dimensions et de poids élevé; les difficultés de mise en oeuvre se présentent notamment pour certaines constructions d'habitation où l'acheminement de ces structures sur le toit ou en hauteur pose des problèmes certains.We can however blame these structures known to be heavy, bulky and unreliable. For metal structures, mounting and disassembly of such protection systems take a lot of time. Additionally, problems arise also in their implementation because these structures are large and heavy; the implementation difficulties arise in particular for certain residential constructions where the routing of these structures on the roof or in height poses certain problems.

Il est donc clair qu'on a besoin d'un système qui, dans une large mesure, permet de remédier aux insuffisances que l'on a rencontrées dans la technique antérieure.It is therefore clear that we need a system which, to a large extent, addresses the shortcomings that we encountered in the technique earlier.

Par conséquent, un but de la présente invention est de fournir un système de sécurité modulable qui offre une grande facilité de mise en oeuvre tout en étant très fiable.Therefore, an object of the present invention is to provide a modular security system that offers great ease of implementation while being very reliable.

Un autre but de la présente invention est de proposer un système de sécurité pour former un échafaudage dont la conception de la structure permet de monter avec des éléments de base, de conception simple, aisés à transporter et de faible encombrement, une structure d'échafaudage rigide et complexe à un ou plusieurs niveaux de travail, ces niveaux de travail pouvant être dans un même plan vertical ou décalés de manière à conférer une grande flexibilité à l'ensemble de la structure d'échafaudage.Another object of the present invention is to propose a security system to form a scaffolding whose structural design allows mount with basic elements, of simple design, easy to transport and compact, rigid and complex scaffolding structure with one or multiple levels of work, these levels of work can be in the same vertical plane or offset by so as to give great flexibility to the whole of the scaffolding structure.

Un autre but de la présente invention est de fournir un système de sécurité tel qu'un échafaudage dont la conception permet une variation rapide et aisée des dimensions de l'échafaudage dans le sens de la largeur ou de la hauteur de la structure tout en étant rigide.Another object of the present invention is to provide a security system such as scaffolding whose design allows quick and easy variation dimensions of the scaffolding in the direction of width or height of the structure while being rigid.

Ces objets ainsi que d'autres sont atteints, suivant l'invention, en ce que le système ajustable de sécurité comprend en outre les caractéristiques de la partie caractérisante de la revendication 1.These and other objects are reached, according to the invention, in that the adjustable system of security further includes the features of the characterizing part of claim 1.

Plus particulièrement, suivant l'invention, le système modulaire ajustable de sécurité, est caractérisé en ce que le premier élément de base est monté à pivotement sur le dispositif raidisseur de liaison pour permettre un pivotement par rapport au second élément de base.

Le système modulaire de l'invention comprend en outre un moyen de verrouillage sécurisé adapté pour s'engager dans les perçages de graduation pour fixer les premier et second éléments de base dans la position angulaire sélectionnée.More particularly, according to the invention, the adjustable modular safety system, is characterized in that the first basic element is mounted to pivoting on the stiffening link device for allow pivoting with respect to the second element of based. The connection stiffening device comprises a plurality of graduation holes intended to adjust the angular position of the first next basic element different predetermined angles to the second basic element. The modular system of the invention further includes secure locking means suitable for engaging in graduation drilling to fix the first and second basic elements in the selected angular position.

Avantageusement, le dispositif raidisseur de liaison comprend deux éléments plats perforés disposées de part et d'autre du second élément de base et un organe de pivotement désaxé par rapport au second élément de base. Des perçages de graduation sont disposés par paires suivant un pas d'angle prédéterminé le long d'arcs de cercle centré sur l'axe de pivotement, et une double clé de verrouillage est utilisée pour s'engager dans une paire de perçages et dans des perforations du premier élément de base pour fixer les éléments dans la position angulaire sélectionnée.Advantageously, the stiffening device of connection includes two perforated flat elements arranged on either side of the second base element and a pivoting member offset from the second basic element. Graduation holes are arranged in pairs at a predetermined angle step along circular arcs centered on the pivot axis, and a double locking key is used to engage in a pair of holes and in perforations of the first basic element to fix the elements in the selected angular position.

    En se référant à la figure 1, une forme de réalisation préférée du système modulable est décrite à titre d'exemple. Le système ajustable de sécurité 10, objet de l'invention, tel que représenté aux figures 1, 2 et 3 est particulièrement adapté à la réalisation d'une structure d'échafaudage à utiliser pour le travail en toiture ou en construction. Ce système de sécurité 10 est aussi utilisable comme structure de base pour le bricolage, tel que la réalisation d'étagères, d'échafaudage intérieur pour plâtrier, peintres, etc., et la réalisation d'une plateforme sur un support irrégulier et/ou en pente.Referring to Figure 1, a form of preferred embodiment of the modular system is described in as an example. The adjustable security system 10, subject of the invention, as shown in Figures 1, 2 and 3 is particularly suitable for the realization a scaffolding structure to be used for work on the roof or under construction. This security system 10 can also be used as a basic structure for the DIY, such as making shelves, interior scaffolding for plasterer, painters, etc., and the realization of a platform on a support irregular and / or sloping.

    L'idée du concept est de composer à partir d'au moins une structure modulaire articulée (kit de base) et des accessoires, des cas de figures aux applications techniques les plus variées.The idea of the concept is to compose from at least minus an articulated modular structure (basic kit) and accessories, cases to applications most varied techniques.

    Ce système modulaire 10 est constitué d'un premier bras de base 12 à emboítement de forme tubulaire et d'un second bras de base 13 à emboítement de forme tubulaire complémentaire au premier bras de base 12.This modular system 10 consists of a first base arm 12 with tubular socket and a second base arm 13 with tubular socket complementary to the first base arm 12.

    Un dispositif raidisseur de liaison 20 et 21 constitué d'un double plat 20 et 21 gradué est fixé aux second bras de base 13 et adapté à raccorder les deux bras de base 12 et 13 suivant un angle prédéterminé.A connection stiffening device 20 and 21 consisting of a double dish 20 and 21 graduated is fixed to second base arm 13 and adapted to connect the two base arms 12 and 13 at a predetermined angle.

    Le premier bras 12 est articulé sur un axe libre 14 au moyen d'une perforation 17 permettant une rotation d'un angle sélectionné entre deux plats 20 et 21 solidaires et le premier bras 12. Les deux plats 20 et 21 comportent une perforation 25 correspondante pour permettre le passage d'un pivot 14. Le premier bras 12 est monté à pivotement sur les deux plats raidisseurs 20 et 21 au moyen du pivot 14 sécurisé par blocage d'un élément de sécurité approprié, ce pivotement s'effectuant librement par rapport au deuxième bras 13 fixé au double plat 20 et 21 raidisseur. L'axe 14 décentré par rapport aux bras fixe 13 permet de régler librement l'angle de connexion entre les deux bras 12 et 13.The first arm 12 is articulated on a free axis 14 by means of a perforation 17 allowing rotation of a selected angle between two dishes 20 and 21 joined together and the first arm 12. The two plates 20 and 21 have a corresponding perforation 25 for allow the passage of a pivot 14. The first arm 12 is pivotally mounted on the two flat stiffeners 20 and 21 by means of pivot 14 secured by blocking a suitable safety element, this pivoting operating freely relative to the second arm 13 fixed to the double plate 20 and 21 stiffener. Axis 14 off center relative to the fixed arm 13 allows adjustment freely the angle of connection between the two arms 12 and 13.

    Le deuxième bras 13 à grand emboítement est de préférence un axe (de section ronde, carrée ou rectangulaire,...) dont une série de perforations 13a permettent un réglage fixe et/ou coulissant à partir de la partie inférieure du dispositif raidisseur 20 et 21 qui comporte des perforations 20a et 21a correspondantes permettant le passage d'une clé sécurisée, ou de boulons avec écrous de sûreté.The second arm 13 with large socket is preferably an axis (round, square or rectangular, ...) including a series of perforations 13a allow fixed and / or sliding adjustment from the lower part of the stiffening device 20 and 21 which has corresponding perforations 20a and 21a allowing the passage of a secure key, or bolts with safety nuts.

    Alternativement, le deuxième bras 13 peut être fixé de manière permanente au dispositif raidisseur 20a et 21a, par exemple par soudage.Alternatively, the second arm 13 can be fixed permanently to the stiffening device 20a and 21a, for example by welding.

    Le premier bras 12 à petit emboítement est de préférence un axe (de section ronde-carrée ou rectangulaire,...) dont une série de perforations 12a permettent une rotation axiale 14 entre le double plat gradué 20 et 21 avec un réglage d'angle sur plus de 180°. Son axe de rotation 14 se fixe à partir de la partie supérieure du dispositif raidisseur 20 et 21, sur un axe décentré 14 par rapport au deuxième bras 13 au moyen de la perforation centrale 25 du double plat 20 et 21 et de la perforation 17 du premier bras 12.The first arm 12 with small socket is preferably an axis (round-square section or rectangular, ...) including a series of perforations 12a allow axial rotation 14 between the double plate graduated 20 and 21 with an angle adjustment of more than 180 °. Its axis of rotation 14 is fixed from the upper part of the stiffening device 20 and 21, on an off-center axis 14 relative to the second arm 13 at by means of the central perforation 25 of the double plate 20 and 21 and the perforation 17 of the first arm 12.

    L'axe central 14 est un axe libre, permettant une rotation désaxée entre les deux bras 12 et 13. Celui-ci peut être renforcé selon usage à l'aide de roulements ou autres.The central axis 14 is a free axis, allowing a off-axis rotation between the two arms 12 and 13. The latter can be reinforced according to use with bearings or other.

    Soit fixe ou coulissant, le double plat raidisseur 20 et 21 permet de guider et de rapporter les efforts dans la ligne axiale, à partir de l'axe 14 décentré de cette pièce.Either fixed or sliding, the double stiffener plate 20 and 21 helps guide and report efforts in the axial line, from axis 14 off-center from this piece.

    Le dispositif raidisseur de liaison 20 et 21 comporte une pluralité de perçages 22 et 23 de graduation pour ajuster la position angulaire du premier bras 12 suivant différents angles prédéterminés par rapport au second bras 13.The connection stiffening device 20 and 21 comprises a plurality of holes 22 and 23 of graduation to adjust the angular position of the first arm 12 at different angles predetermined by compared to the second arm 13.

    Une ou plusieurs clés de verrouillage 15 et 16, par exemple par goupilles de sécurité, sont utilisées pour s'engager dans les perçages de graduation 22 et 23 et dans des perforations 12a correspondantes du premier bras 12 pour fixer la position angulaire sélectionnée entre les deux bras 12 et 13.One or more locking keys 15 and 16, for example by safety pins, are used to engage in graduation holes 22 and 23 and in corresponding perforations 12a of the first arm 12 to fix the selected angular position between the two arms 12 and 13.

    Comme on peut le voir en figure 3, selon un mode de réalisation préféré de l'invention, à titre d'exemple, pour chaque pas d'angle de 15 degrés le dispositif double plat raidisseur 20 et 21 comporte une paire de perçages, chaque paire étant espacée d'un angle 15 degrés par rapport à l'axe central 25. Plus spécifiquement, les perçages 22 sont divisés en quatre séries de perçages 22a, 22b, 22c, 22d disposées chacune sur un arc de cercle en alternance à une distance prédéterminée de l'axe central 25. Sur chaque arc de cercle, les perçages 22a, 22b, 22c, 22d sont espacés de 30 degrés par rapport à l'axe central 25 et les arc de cercles sont équidistants. Les perçages de la 1ière et 3ème série 22a et 22c sont disposés à des angles intermédiaires de 15, 45, et 75 degrés alors que les perçages de la 2ème et 4ème série 22b et 22c sont disposés à des angles de 0, 30, 60, et 90° (en alternance) pour obtenir un pas d'angle relativement petit (15°).As can be seen in Figure 3, according to a mode preferred embodiment of the invention, as example, for each 15 degree angle step the double flat stiffener device 20 and 21 includes a pair of holes, each pair being spaced at an angle 15 degrees to the center line 25. More specifically, the holes 22 are divided into four series of holes 22a, 22b, 22c, 22d each arranged on an arc alternating at a distance of the central axis 25. On each arc of circle, the holes 22a, 22b, 22c, 22d are spaced apart 30 degrees from the central axis 25 and the arc of circles are equidistant. The holes of the 1st and 3rd series 22a and 22c are arranged at angles intermediate 15, 45, and 75 degrees while the holes of the 2nd and 4th series 22b and 22c are arranged at angles of 0, 30, 60, and 90 ° (in alternation) to obtain a relatively angle step small (15 °).

    Les perforations 22, 23, 12a permettent des connexions (en traction et en compression), à l'aide de une ou plusieurs clé de sûreté 15 et 16.The perforations 22, 23, 12a allow connections (in tension and compression), using one or more security keys 15 and 16.

    Dans la forme d'exécution illustrée sur la figure 1 et figure 3, le dispositif de verrouillage 15 et 16 comporte une double clé 15 et 16 de sécurité et la disposition des perçages 22, 23, et 12a permet d'ajuster la position angulaire du bras 12 par rapport au bras 13 par pas de 15 degrés tout en maintenant la rigidité du double plat raidisseur 20 et 21. La double clé de sécurité peut être formée de deux clavettes 15 et 16 reliées par un élément de liaison et sécurisée par blocage d'une double goupille ou tout autre élément de sûreté.In the embodiment illustrated in Figure 1 and Figure 3, the locking device 15 and 16 has a double security key 15 and 16 and the arrangement of the holes 22, 23, and 12a makes it possible to adjust the angular position of the arm 12 relative to the arm 13 in 15 degree steps while maintaining the rigidity of the double flat stiffener 20 and 21. The double key safety can be formed by two keys 15 and 16 connected by a connecting element and secured by locking of a double pin or any other element of safety.

    Les plats gradués 20 et 21 sont soit fixes ou coulissants et permettent de rapporter les efforts dans la ligne axiale centrale de ces pièces 20 et 21. Alternativement, le dispositif raidisseur de liaison peut par exemple être formé d'un simple plat enforme de U complémentaire au bras 13 coulissant, avec deux éléments similaires aux pièces 20 et 21 et un élément perpendiculaire qui les relient.Graduated dishes 20 and 21 are either fixed or sliding and allow to report efforts in the central axial line of these parts 20 and 21. Alternatively, the link stiffening device can for example be formed of a simple dish in the form of U complementary to the sliding arm 13, with two elements similar to parts 20 and 21 and an element perpendicular that connect them.

    La ou les clés de sécurité 15 et 16 ajustables au niveau du premier bras 12, permettent de démultiplier la résistance au niveau des axes de connexions.Security key (s) 15 and 16 adjustable to level of the first arm 12, allow to multiply the resistance at the connection axes.

    La traction et/ou la compression se situent au niveau de la ou des connexions à l'aide de la clé de sécurité (au minimum une) en fonction des pièces 12, 20, 21 coulissants entre elles.Traction and / or compression are located at level of the connection (s) using the security (at least one) depending on parts 12, 20, 21 sliding between them.

    D'autre part, le bras 13 est fixe sur sa base. Les plats raidisseurs 20 et 21 sont soit fixes ou coulissants. Les perforations graduées entre le bras 12 et le double plat 20 et 21 permettent de rigidifier la connexion à l'angle désiré de façon précise et définie, et d'être sécurisé à l'aide d'une clé de sécurité au minimum.On the other hand, the arm 13 is fixed on its base. The flat stiffeners 20 and 21 are either fixed or sliding. The graduated perforations between the arm 12 and the double plate 20 and 21 allow to stiffen the connection to the desired angle in a precise and defined manner, and be secured using a security key at minimum.

    Le bras 12 et les deux plats 20 et 21 guident et garantissent une parfaite stabilité angulaire à partir de l'axe central 25.The arm 12 and the two plates 20 and 21 guide and guarantee perfect angular stability from of the central axis 25.

    Il est à noter que pour sécuriser le rigidité du système modulaire 10 assemblé à un autre système modulaire du même type ou à divers accessoires, il est prévu au moins une rangée de perforations 12a, 12b, 12c, 12d, 13a, 13b, 13c supplémentaires dans chacun des bras 12 et 13. Ces perforations(figures 3) peuvent être disposées suivant une double rangée désaxée 12b et 13b de perforations équidistantes et/ou une simple rangée axiale 12a, 12c, 12d, 13a, 13c de perforations équidistantes dans deux faces opposées des bras 12 et 13, ou dans toutes les faces des bras 12 et 13. Le double plat 20 et 21 est muni de perforations 20a et 21a analogues.It should be noted that to secure the rigidity of the modular system 10 assembled with another system of the same type or with various accessories, it is provided with at least one row of perforations 12a, 12b, 12c, 12d, 13a, 13b, 13c additional in each of the arms 12 and 13. These perforations (Figures 3) can be arranged in a double offset row 12b and 13b equidistant perforations and / or a single row axial 12a, 12c, 12d, 13a, 13c of perforations equidistant in two opposite faces of the arms 12 and 13, or in all the faces of the arms 12 and 13. The double plate 20 and 21 is provided with perforations 20a and 21a like.

    Toutes ces perforations sont destinées à recevoir une connexion sécurisée avec au moins une clé de sûreté après assemblage par emboítement coulissant de l'autre système modulaire ou de l'accessoire jusqu'à une position sélectionnée. Ainsi, ces perforations permettent l'utilisation de clé de sûreté (une au plus) pour des connexions sécurisées lors d'application modulables bien définies. La clé de sûreté peut être formée d'un goujon verrouillable au moyen d'une goupille ou une clavette. La clé de sûreté est de préférence une double clé en U avec deux éléments espacés de manière à pouvoir s'insérer dans deux perforations adjacentes dans la double rangée désaxée 12b et 13b et/ou dans les simples rangées axiales 12a, 12c, 12d, 13a, 13c, 20a, et 21a. All these perforations are intended to receive a secure connection with at least one security key after assembly by sliding socket on the other modular system or accessory up to a selected position. So these perforations allow the use of a security key (one at most) for secure connections during application modular well defined. The security key can be formed by a stud which can be locked by means of a pin or a key. The security key is preferably a double U-shaped key with two elements spaced so as to ability to fit into two adjacent perforations in the offset double row 12b and 13b and / or in the single axial rows 12a, 12c, 12d, 13a, 13c, 20a, and 21a.

    A lui seul, le système de base 10 permet une application simple en tant que pied mobile et modulable. Ce système de base permet un réglage de pied en fonction de la déclinaison de l'appui pour obtenir une plateforme stable. L'angle désiré est sécurisé à l'aide d'une clé de sécurité et les lisses coulissantes et réglables permettent une parfaite stabilité.The basic system 10 alone allows simple application as a movable and modular stand. This basic system allows a foot adjustment according of the declination of support to obtain a platform stable. The desired angle is secured with a key safety and sliding and adjustable rails allow perfect stability.

    En outre, le système de base s'adapte à de nombreuses configurations d'installation d'échafaudage: posé sur le sol, posé sur un escalier, en toiture, en traversée de mur, en base de rampant, ou sur échelle.In addition, the basic system adapts to numerous scaffolding installation configurations: posed on the ground, posed on a staircase, in roofing, in wall crossing, crawling base, or ladder.

    Conformément à l'invention, la structure d'échafaudage de sécurité, représentée aux figures 4 à 17, est une structure dite du type portée par la construction. Elle est plus particulièrement destinée à être utilisée pour la réalisation ou l'entretien des toitures d'une construction ou en tant qu'échafaudage vertical le long d'un mur d'une construction.According to the invention, the structure safety scaffolding, shown in Figures 4 to 17, is a structure called of the type carried by the construction. It is more particularly intended for be used for the realization or maintenance of roofs of a building or as scaffolding vertical along a wall of a building.

    La structure d'échafaudage est munie d'un organe d'attelage 40 pour accrocher l'échafaudage à un élément de construction. L'élément de construction sur lequel est fixé l'échafaudage peut être un mur ou un élément de charpente de ladite construction. Dans l'exemple de réalisation représenté en figure 4, l'élément de construction est constitué par un toit 2.The scaffolding structure is provided with a member coupling 40 for hanging the scaffolding to an element of construction. The building element on which is fixed the scaffolding can be a wall or an element of frame of said construction. In the example of embodiment shown in Figure 4, the element of construction consists of a roof 2.

    L'échafaudage 100 de la figure 4 est constitué de deux systèmes modulaires 10 et 110 du type de la figure 1 emboítés et en position raccordée à une toiture 2. Cet échafaudage est plus particulièrement adapté à la réalisation ou à la réfection de la toiture de construction. Cet échafaudage 110 suspendu comprend une structure d'attelage 40 agencée pour pouvoir être raccordée à ladite construction par au moins un point d'ancrage 40 et une structure d'appui 120 comportant au moins un point d'appui 50 situés à des niveaux différents du toit 2. A cet effet l'extrémité du double plat 20 et 21 forme une tête d'accroche 40 au moyen de perforations correspondantes. Cette structure d'échafaudage 100 comporte au moins deux modules 10 et 110 à deux bras tels que représentés en figure 1.The scaffolding 100 of FIG. 4 consists of two modular systems 10 and 110 of the type of the figure 1 nested and in position connected to a roof 2. This scaffolding is more particularly suited to the realization or repair of the roof of construction. This suspended scaffolding 110 comprises a coupling structure 40 arranged to be connected to said construction by at least one point anchor 40 and a support structure 120 comprising at minus a support point 50 located at levels different from the roof 2. For this purpose the end of the double flat 20 and 21 forms a gripping head 40 by means of corresponding perforations. This structure scaffolding 100 comprises at least two modules 10 and 110 with two arms as shown in FIG. 1.

    Cette structure d'échafaudage suspendu, agencée pour se raccorder à la construction par au moins un point d'ancrage 40 et plusieurs points d'appui 50 à 54 situés à des niveaux différents, comprend au moins deux systèmes modulaires 10 et 110. Chaque système modulaire 10 et 110 de la structure d'échafaudage est ajustable pour changer l'angle d'inclinaison en fonction des besoins et, par pivotement des bras, pour constituer à chaque fois un support d'élément de plancher horizontal et un support d'élément de garde-corps vertical, indépendamment de l'inclinaison de la toiture.This suspended scaffolding structure, arranged to connect to the building by at least one anchor point 40 and several support points 50 to 54 located on different levels, includes at least two modular systems 10 and 110. Each modular system 10 and 110 of the scaffolding structure is adjustable to change the tilt angle according to needs and, by pivoting the arms, to constitute each time a horizontal floor element support and a vertical railing element support, regardless of the inclination of the roof.

    Comme le montrent les figures 4 à 17, au moins deux éléments modulaires 10 et 110 sont nécessaires pour constituer un module d'échafaudage pour la constitution d'un niveau de plancher horizontal. Chaque élément modulaire 10 et 110 du module d'échafaudage est généralement disposé sensiblement orthogonalement à l'élément de construction 2. Dans ce cas, le premier système modulaire 110 du module d'échafaudage 100 est raccordée par une tête d'ancrage 40 sur un crochet de service 41 et par quatre points d'appui 50-53 à l'élément de construction 2. Les deux éléments modulaires 10 et 110 sont emboítés l'un dans l'autre par emboítement des bras tubulaires complémentaires 13 et 112. Le premier bras 12 formant montant est adapté à supporter des éléments de sécurité tels que des éléments de garde-corps ou des filets, et le second bras 13 forme un piétement en vue de réaliser une plate-forme de travail. As shown in Figures 4 to 17, at least two modular elements 10 and 110 are required for constitute a scaffolding module for the constitution a horizontal floor level. Each element modular 10 and 110 of the scaffolding module is generally arranged substantially orthogonally to building element 2. In this case, the first modular system 110 of the scaffolding module 100 is connected by an anchor head 40 on a hook service 41 and by four support points 50-53 to building element 2. The two elements modular 10 and 110 are fitted into each other by fitting of complementary tubular arms 13 and 112. The first arm 12 forming an upright is adapted to support security features such as elements of guardrails or nets, and the second arm 13 forms a base in order to create a platform for job.

    Il convient de relier, par sécurité, chaque console par une élingue de sûreté à un élément solide de la construction pour éviter son renversement en cas de défaillance.It is advisable to connect, for safety, each console by a safety sling to a solid element of the construction to prevent overturning in the event of failure.

    Bien évidemment, d'autres systèmes modulaires peuvent être raccordés à la construction de manière analogue pour compléter la structure d'échafaudage suivant la longueur désirée. Une fois la structure d'échafaudage est à ce moment prête à recevoir un intervenant et/ou des charges.Obviously, other modular systems can be connected to the building so analogous to complete the scaffolding structure according to the desired length. Once the structure at this time is ready to receive a intervener and / or charges.

    Comme le montre la figure 5, les points d'appui 50 à 54 sont de préférence répartis latéralement par l'utilisation d'un profilé 120 en T emboítable dans le second bras 113. Le profilé 120 est composé de deux axes (de section ronde, carrée, ou rectangulaire,....) juxtaposés de façon symétrique, sur une de ses extrémités.As shown in FIG. 5, the support points 50 to 54 are preferably distributed laterally by the use of a nestable T-profile 120 in the second arm 113. Profile 120 is composed of two axes (round, square, or rectangular section, ....) symmetrically juxtaposed on one of its ends.

    Les perforations 121 et 122 permettent l'utilisation de clés de sûreté pour des connexions sécurisées lors d'applications modulables bien définies.Perforations 121 and 122 allow the use of security keys for connections secure during well-defined modular applications.

    Cette pièce 120 est utilisable tant vers le bas que ver le haut.This part 120 can be used both downwards and upwards.

    En outre, avantageusement, les points d'appui 50 à 54 peuvent être repartis longitudinalement par l'adjonction d'une articulation 130 et 131 sur roulettes 134 et 135 de part et d'autre de la base du profilé 120 en T. Cette articulation 130 et 131 comporte un plat 140 en forme de "banane". Son axe central sert de moyen de connexion (goupille), avec un connecteur d'appui 150 et 151 à emboítement coulissant sécurisé. Les deux perforations du plat 140 reçoivent l'articulation des roues 134 et 135 ou autres systèmes d'appui (figure 18).In addition, advantageously, the support points 50 to 54 can be distributed longitudinally by the addition of a joint 130 and 131 on casters 134 and 135 on either side of the base of profile 120 T-shaped joint 130 and 131 has a flat 140 shaped like a "banana". Its central axis serves as a means of connection (pin), with a support connector 150 and 151 with secure sliding socket. Both perforations in plate 140 receive the articulation of wheels 134 and 135 or other support systems (figure 18).

    L'articulation sur roulettes 130 et 131 permet en outre de faciliter le transport de la structure et l'accrochage de celle-ci, sur la toiture ou le long d'une construction au moyen d'un hauban et ainsi éviter les risques d'accident lors de sa mise en place.The articulation on casters 130 and 131 allows besides facilitating the transport of the structure and hanging it, on the roof or along of a construction by means of a stay cable and thus avoid the risk of accident during its installation.

    Le connecteur d'appui 150 et 151 coulissant est un accessoire qui peut être utilisé sur tout supports. Il est constitué d'un axe 153 (rond, carré ou rectangulaire...), pouvant coulisser librement de part et d'autres de l'axe du T 120, est utilisable dans tous les sens (en bas ou en haut). Le dispositif d'appui 150 est perforé afin de recevoir des connexions sécurisées lors d'applications modulables précises.The sliding connector 150 and 151 is a accessory which can be used on any support. he consists of an axis 153 (round, square or rectangular ...), which can slide freely on both sides and others from the T 120 axis, can be used in all sense (bottom or top). The support device 150 is perforated to receive secure connections during precise modular applications.

    La courbure 154 en U composant la pièce 150 et 151 permet de servir d'appui.The curvature 154 in U making up the part 150 and 151 allows to serve as support.

    L'axe tubulaire 155 fixé au droit de l'axe et de la courbure de cette pièce 150 et 151 permet de recevoir l'axe 136 de l'articulation 130 et 131 sur roulettes.The tubular axis 155 fixed to the right of the axis and the curvature of this part 150 and 151 makes it possible to receive the axis 136 of the joint 130 and 131 on casters.

    Les figures 6, 7, 8 et 9 illustrent la possibilité de prolonger les bras 12 et 113 des systèmes modulables 10 et 110 par l'adjonction d'allonges 60, 61 et 160 de différentes longueurs. Ces allonges 60, 61 et 160 forment chacunes un axe (rond, carré ou rectangulaire...), composé de deux pièces soudées dont la section est différente, afin de permettre un emboítement sécurisé sur les bras 12, 13, 112, 113 (mâle-femelle), à l'aide de une (au minimum) clé de sûreté, pour des applications modulables définies.Figures 6, 7, 8 and 9 illustrate the possibility extend the arms 12 and 113 of the modular systems 10 and 110 by adding extensions 60, 61 and 160 of different lengths. These extensions 60, 61 and 160 each form an axis (round, square or rectangular ...), composed of two welded parts whose section is different, to allow a secure nesting on the arms 12, 13, 112, 113 (male-female), using one (at least) security key, for applications modular defined.

    Dans la figure 6, une allonge 60 de longueur moyenne est emboítée au bras 12 pour le garde-corps et une grande allongé 160 est emboítée au bras 113 et au profilé 120 pour l'appui des roues sur des points éloignés du toit 2.In FIG. 6, an extension 60 of length medium is fitted to the arm 12 for the railing and a large elongated 160 is fitted to the arm 113 and to the profile 120 for supporting the wheels on points away from the roof 2.

    Dans la figure 8, une allonge 61 plus petite est emboítée au bras 12 selon les besoins pour le garde-corps.In Figure 8, a smaller extension 61 is fitted to the arm 12 as necessary for the railing.

    Comme le montre la figure 19, en cas de charges excessivement lourdes, il est possible d'ajouter une triangulation de renfort 68 entre les deux bras 12 et 13 du système modulable 10.As shown in figure 19, in case of loads excessively heavy, it is possible to add a reinforcement triangulation 68 between the two arms 12 and 13 modular system 10.

    Il est à noter que pour sécuriser la rigidité de la structure d'échafaudage, il est prévu un moins une rangée de perforations équidistantes dans chacun des accessoires 60, 61, 160, 120, 130, 150 emboítables utilisés. Ces perforations sont analogues à celles des deux bras du système modulaire. Ces perforations peuvent être disposées suivant une double rangée désaxée de perforations équidistantes et/ou une simple rangée axiale de perforations équidistantes dans deux faces opposées des accessoires, ou dans toutes les faces des accessoires. Ces perforations sont destinées à recevoir une connexion sécurisée avec au moins une clé de sûreté après assemblage par emboítement coulissant de l'accessoire sur le système modulaire jusqu'à une position sélectionnée.It should be noted that to secure the rigidity of the scaffolding structure there is provided a minus one row of equidistant perforations in each of accessories 60, 61, 160, 120, 130, 150 nestable used. These perforations are similar to those of two arms of the modular system. These perforations can be arranged in a double offset row of equidistant perforations and / or a single row axial of equidistant perforations in two faces opposite accessories, or in all sides of accessories. These perforations are intended to receive a secure connection with at least one security key after assembly by sliding socket of the accessory on the modular system up to a selected position.

    Les accessoires permettent donc tous l'utilisation de clé de sûreté (une au plus) pour des connexions sécurisées lors d'applications modulables bien définies.The accessories therefore allow all use security key (one at most) for connections secure during well-defined modular applications.

    Comme le montrent les figures 8 et 9, le système modulaire 110 peut être raccordé par son point d'ancrage 40 au crochet de service 41 au moyen d'une accroche d'amortissement mobile 42, comportant un ou plusieurs maillons de chaíne 140 (figure 18).As shown in Figures 8 and 9, the system modular 110 can be connected by its anchor point 40 on the service hook 41 by means of a hook mobile damping unit 42, comprising one or more chain links 140 (figure 18).

    Cette accroche mobile 42 est composée de un ou plusieurs plats 140 en forme de "banane" avec perforations identiques à ceux de l'articulation 130 et 131 sur roulettes mais utilisés dans une autre application. L'accroche mobile 42 en forme de chaíne permet d'amortir la charge sur les différents éléments constituants. Une plaque 43 de séparation peut être introduite sous le point d'ancrage 40 pour éviter d'endommager la toiture. This movable hanger 42 is composed of one or several 140 banana-shaped dishes with perforations identical to those of joint 130 and 131 on casters but used in another application. The mobile hook 42 in the form of a chain allows to absorb the load on the different elements components. A separation plate 43 can be introduced under anchor point 40 to avoid damage the roof.

    Cette structure d'échafaudage peut être adaptée à tout type de pente.This scaffolding structure can be adapted to any type of slope.

    La tête d'accroche 40 du double plat s'adapte à tout type d'ancrage (crochet de service...), et l'ensemble du concept peut être muni d'une élingue de sécurité. Tous les accessoires sont utilisables en fonction des exigences rencontrées: articulation sur roulettes, lisse réglable, accroche-amortisseur, etc.The attachment head 40 of the double plate adapts to any type of anchor (service hook, etc.), and all of the concept can be fitted with a safety sling. All accessories can be used depending on the requirements encountered: articulation on casters, smooth adjustable, shock absorber, etc.

    L'approche d'utilisation étant technique, il faut tenir compte de la répartition des appuis, en fonction des charges permises, les normes de sécurité étant d'application.The approach of use being technical, it is necessary take into account the distribution of support, depending permitted loads, safety standards being application.

    Les figures 10, 11 et 12 illustrent une structure d'échafaudage 200 constituée de trois systèmes modulaires 10, 110 et 210, utilisable en sous-corniche. En outre, cette structure comprend une articulation 130 et 131 sur roulettes, un profilé 120 en T, une accroche mobile d'amortissement 42, et des allonges 60 et 61 courtes, moyennes ou longues pour appui et/ou garde-corps à choisir selon la situation. De plus, si nécessaire, cette structure d'échafaudage peut comporter une allonge 62 supplémentaire de connexion emboítable sur le bras 12 et fournissant une tête d'ancrage allongée pour l'accroche mobile d'amortissement 42 pour des travaux en sous-corniche.Figures 10, 11 and 12 illustrate a structure scaffolding 200 consisting of three systems modular 10, 110 and 210, usable as a sub-cornice.

In addition, if necessary, this scaffolding structure may include an additional extension 62 for plug-in connection on arm 12 and providing an anchor head extended for the movable damping hook 42 for work in the sub-cornice.

    La variante de la figure 12 illustre une structure d'échafaudage 200 similaire comprenant une allonge 62 supplémentaire pour assurer un déplacement en hauteur, et pour permettre un accès sécurisé pour des travaux plus bas en sous-corniche.The variant of Figure 12 illustrates a structure of scaffolding 200 similar comprising an extension 62 additional to ensure a displacement in height, and to allow secure access for work lower down under the cornice.

    Cette structure 200 peut être utilisée sous forme de garde-corps et de moyen d'accès sécurisé pour des travaux difficile d'accès avec un système composé de trois systèmes modulaires. L'appui du concept en partie basse se fait soit par lisse en T (fixe ou mobile) soit par articulation sur roulette.This structure 200 can be used in the form of guardrails and secure means of access for work difficult to access with a system composed of three modular systems. Support for the concept in part bass is done either by T-bar (fixed or mobile) or by articulation on caster.

    L'ancrage se fait en partie haute à l'aide d'une accroche provisoire ou définitive.The anchoring is done in the upper part using a temporary or final catch.

    Suivant une variante de la structure d'échafaudage 100 à deux systèmes modulaires 10 et 110 en traversée de mur illustré en figures 13, 14 et 15, un crochet mural 70 fixé à un mur de construction 3 est muni d'un organe d'accrochage 72 au mur 3 d'une part et d'autre part d'un organe d'attelage 70 à la tête d'ancrage 40 de la structure d'échafaudage 100. L'organe d'accrochage 70 est de préférence inséré entre deux blocs de construction du mur 3 et fixé de l'autre côté du mur par un élément de sécurité traversant le perçage 72.According to a variant of the scaffolding structure 100 to two modular systems 10 and 110 crossing wall illustrated in figures 13, 14 and 15, a wall hook 70 fixed to a building wall 3 is provided with a member hooking 72 to the wall 3 on the one hand and on the other hand of a coupling member 70 to the anchoring head 40 of the scaffolding structure 100. The fastening member 70 is preferably inserted between two blocks of construction of wall 3 and fixed on the other side of the wall by a security element passing through the bore 72.

    La structure d'échafaudage 100 destinée à être attelée, au moyen de l'organe d'attelage 70 au mur 3 comporte un dispositif d'appui 120, 130 et 131 à roulettes coulissant contre le mur comme décrit plus haut.The scaffolding structure 100 intended to be coupled, by means of the coupling member 70 to the wall 3 includes a support device 120, 130 and 131 to casters sliding against the wall as described more high.

    En outre, une allonge 60 pour garde-corps peut être emboítée au bras 12 si nécessaire.In addition, an extension 60 for railing can be fitted to the arm 12 if necessary.

    Comme le montre la figure 15, une allonge 62 permettant un déplacement en hauteur peut être emboítée entre le profilé 120 en T et le système modulaire 110 pour permettre un déplacement en hauteur le long du mur 3 et déplacer les points d'appui en partie basse. Une accroche mobile simple 42 composée de deux plats 140 en forme de "banane" peut être accrochée à l'organe d'attelage 70 pour faciliter la mise en place de la structure d'échafaudage.As shown in Figure 15, an extension 62 allowing a displacement in height can be nested between the T-profile 120 and the modular system 110 to allow a displacement in height along the wall 3 and move the support points in the lower part. A simple mobile hook 42 composed of two dishes 140 in "banana" shape can be hung on the organ coupling 70 to facilitate the installation of the scaffolding structure.

    Les figures 16 et 17 illustrent une structure d'échafaudage 300 utilisable sur une échelle 310. En particulier, cette structure 300 comprend deux systèmes modulaires 10 et 110 et est accrochée ou d'appui sur deux échelons espacés de l'échelle 310. Figures 16 and 17 illustrate a structure scaffolding 300 usable on a ladder 310. In particular, this structure 300 comprises two systems modular 10 and 110 and is hung or supported on two steps spaced from the 310 scale.

    La structure 300 comporte deux profilés 120 en T et quatre éléments 150 d'accroche coulissants. Un premier profilé 120 en T est fixé par goujon et goupilles de sécurité sur le double plat 20 et 21 et le deuxième profilé 120 en T est emboíté dans le bras 13. Les perforations correspondantes permettent l'utilisation de clés de sûreté pour des connexions sécurisées.Structure 300 comprises two T-shaped profiles 120 and four sliding hook elements 150. A first profile 120 in T is fixed by dowel and pins safety on the double dish 20 and 21 and the second profile 120 in T is fitted in the arm 13. The corresponding perforations allow the use of security keys for secure connections.

    Les éléments d'accroche 150 coulissants sont prévus pour être utilisés sur échelle normalisée. Ils comportent un axe 153 (rond, carré ou rectangulaire...), pouvant coulisser librement de part et d'autres de l'axe en T 120, utilisable dans tous les sens (en bas ou en haut).Sliding hooking elements 150 are provided to be used on a standard scale. They have an axis 153 (round, square or rectangular ...), can slide freely on both sides of the axis in T 120, usable in all directions (bottom or high).

    Cette pièce 150 est perforée afin de recevoir des connexions sécurisées lors d'applications modulables précises.This part 150 is perforated in order to receive secure connections during modular applications accurate.

    La courbure 154 en U composant la pièce 150 permet de servir soit d'appui soit d'accroche sur l'échelon 311 et 312 de l'échelle 310.The curvature 154 in U making up the part 150 allows to serve as support or grip on the 311 step and 312 of scale 310.

    L'axe circulaire 155 fixé au droit de l'axe 153 et de la courbure 154 de cette pièce 150 permet de recevoir l'axe de l'appui à roulettes 130 et 131.The circular axis 155 fixed to the right of the axis 153 and of the curvature 154 of this part 150 makes it possible to receive the axis of the roller support 130 and 131.

    Avantageusement, dans une variante non-illustrée, la structure 300 peut comporter une allonge emboítée entre le bras 13 et le profilé 150 pour prendre appui sur un échelon inférieur de l'échelle.Advantageously, in a variant not illustrated, the structure 300 may include a nested extension between arm 13 and profile 150 to take support on a lower rung of the scale.

    Cette structure 300 permet de moduler un petit échafaudage adaptable à tout type d'échelles normalisées. Le concept est composé d'une tête d'appui et d'accroche simple ou double. Les accessoires sont utilisables en fonction des exigences rencontrées.This structure 300 makes it possible to modulate a small scaffolding adaptable to any type of ladder standardized. The concept consists of a support head and single or double grip. The accessories are usable according to the requirements encountered.

    Le jeu d'assemblage de deux systèmes modulaires 10 et 110 permet de résoudre de nombreux cas de figures, applicables dans des domaines aussi variés que la construction, l'industrie, et le bricolage, sous une nouvelle approche d'application.The assembly game of two modular systems 10 and 110 solves many scenarios, applicable in fields as varied as construction, industry, and DIY, under one new application approach.

    Dans les exemples représentés dans toutes les figures, les éléments de plancher sont disposés de manière horizontale de manière à former un premier niveau de travail pour l'opérateur et pouvant supporter un plancher.In the examples shown in all figures, the floor elements are arranged horizontally so as to form a first working level for the operator and able to support a floor.

    Par ailleurs, comme le montrent l'ensemble des figures, l'un des bras verticaux du système modulaire constitue un garde-corps qui peut être conformé pour recevoir des éléments, tels que des planches, reliant deux côtés verticaux de systèmes modulaires adjacents entre eux pour former une lisse.Furthermore, as all of the figures, one of the vertical arms of the modular system constitutes a railing which can be shaped to receive items, such as boards, connecting two vertical sides of adjacent modular systems between them to form a smooth.

    Pour permettre une protection optimale, l'un quelconque des bras de base 12 et 13 du système modulaire 10 peut recevoir par emboítement verrouillé soit un autre système modulaire 110, soit un accessoire comportant un élément à emboítement de forme tubulaire complémentaire, comme une allonge 60, 61, 62, ou un profilé 120 en T.To allow optimal protection, one any of the base arms 12 and 13 of the system modular 10 can receive by locked socket either another modular system 110 or an accessory comprising a tubular shaped interlocking element complementary, such as an extension 60, 61, 62, or a profile 120 in T.

    Par ailleurs, comme les éléments tubulaires constitutifs des bras et des accessoires de chaque système modulaire sont creux, ils peuvent servir à recevoir d'autres éléments à coulissement comme par exemple une allonge 61 avec une ou plusieurs accroches garde-corps 65 prolongeables (voir figure 19) pour permettre de varier les dimensions de la structure selon la situation en présence.Besides, like the tubular elements components of the arms and accessories of each modular system are hollow they can be used to receive other sliding elements such as example an extension 61 with one or more hooks 65 extendable railings (see Figure 19) for allow the dimensions of the structure to be varied according to the situation at hand.

    Les emboítements des systèmes modulaires et des accessoires sont tous verrouillés par des connexions sécurisées à travers les perforations des divers éléments constitutifs, par exemple au moyen de goujons munis de goupilles de sûreté ou de clavettes.The sockets of modular systems and accessories are all locked by connections secured through the perforations of the various components, for example by means of studs fitted with safety pins or keys.

    Pour faciliter la fabrication de telles structures d'échafaudage, chaque élément modulaire 10 est réalisé au moyen de corps tubulaires à emboítement de section quelconque pour avoir des extrémités libres susceptibles d'être raccordées à une extrémité libre d'un corps tubulaire d'un élément contigu. Il est ainsi possible de raccorder, au-dessus de la structure modulaire 10 et 100 représenté aux figures, non pas simplement un garde-corps, mais une structure modulaire identique pour former une double plate-forme (deux étages) par simple emboítement verrouillé des extrémités libres des corps tubulaires constitutifs des côtés verticaux du système modulaire de base 10.To facilitate the manufacture of such structures scaffolding, each modular element 10 is made by means of tubular bodies with cross-section any to have free ends likely to be connected to a free end of a body tubular of a contiguous element. It is thus possible to connect, above the modular structure 10 and 100 shown in the figures, not just a railing, but an identical modular structure for form a double platform (two floors) by single interlocking locked free ends of bodies tubular constituting the vertical sides of the system basic modular 10.

    De la même manière, il est possible d'adjoindre dans le prolongement de chaque structure d'échafaudage de base un autre second système modulaire 10 par simple emboítement verrouillé respectivement dans chaque extrémité libre des corps tubulaires constitutifs de ce système modulaire supplémentaire et dans chaque extrémité libre correspondante des éléments modulaires constitutifs du système modulaire de base pour former un échafaudage en escalier.In the same way, it is possible to add in line with each scaffolding structure basic another second modular system 10 by simple socket locked respectively in each free end of the tubular bodies making up this additional modular system and in each corresponding free end of modular elements components of the basic modular system to form a staircase scaffolding.

    Il en résulte un montage aisé de l'ensemble de la structure d'échafaudage indépendamment de la construction souhaitée.This results in easy mounting of the entire scaffolding structure regardless of desired construction.

    Les structures d'échafaudage permettant, de manière en soi connue, de délimiter un chemin de circulation des intervenants, cette circulation pouvant être effectuée en toute sécurité grâce à la présence d'un garde-corps (non représenté) constitué de planches supportées par les bras verticaux des systèmes modulaires adjacents, et un plancher (non-représenté) constitué de planches supportées par les bras horizontaux. La constitution de l'échafaudage en lui-même ne sera pas décrite de manière plus détaillée car elle est bien connue à ceux versés dans cet art. The scaffolding structures allowing, so in itself known, to delimit a path of circulation of stakeholders, this circulation can be carried out safely thanks to the presence of a guardrail (not shown) consisting of boards supported by the vertical arms of the adjacent modular systems, and a floor (not shown) made up of planks supported by the horizontal arms. The constitution of the scaffolding itself will not be described in a way more detailed as it is well known to those versed in this art.

    Grâce à sa conception, une telle structure empêche tout risque de basculement et tout risque d'entraínement en rotation de la structure d'échafaudage autour d'un axe sensiblement vertical passant par son point d'appui sur la construction et son point d'attelage à l'organe d'accrochage du dispositif. Un tel dispositif limite donc de manière importante les risques d'accident.Thanks to its design, such a structure prevents any risk of tipping and any risk of entrainment rotating the scaffolding structure around a substantially vertical axis passing through its fulcrum on the construction and its point of attachment to the body of attachment of the device. Such a limiting device therefore significantly the risk of accident.

    Comme on peut le voir clairement aux figures 1 à 17 le système de protection de l'invention est très fiable en particulier grâce à l'utilisation des dispositifs raidisseurs de liaison et des connexions sécurisées entre les divers éléments constitutifs. En outre, le dispositif de l'invention est facile à transporter par pivotement des bras des systèmes modulaires en position parallèles.As can be clearly seen in Figures 1 to 17 the protection system of the invention is very reliable especially through the use of devices link stiffeners and secure connections between the various constituent elements. In addition, the device of the invention is easy to transport by pivoting of the arms of the modular systems in position parallel.

    Une telle réalisation d'échafaudage permet donc d'obtenir avec des éléments de base, de conception simple, aisés à transporter et de faible encombrement, une structure d'échafaudage complexe à un ou plusieurs niveaux de travail, ces niveaux de travail pouvant être dans un même plan vertical ou décalés de manière à conférer une grande flexibilité à l'ensemble de la structure d'échafaudage sans nuire toutefois au montagne et la mise en place de cet échafaudage sur l'élément de construction.Such a scaffolding construction therefore allows to get with basic, design elements simple, easy to transport and compact, a complex scaffolding structure with one or more work levels, these work levels can be in the same vertical plane or offset so as to give great flexibility to the whole scaffolding structure without harming the mountain and the installation of this scaffolding on the element of construction.

    De nombreuses variantes apparaítront clairement pour les spécialistes de la technique compte tenu de la description qui précède et des dessins annexés. Par exemple, le dispositif d'articulation sur roulettes peut être modifié ou éliminé, l'appui étant alors assuré contre la toiture ou contre le mur de la construction par la base du profilé en T, si un coût plus faible était désiré.Many variations will appear clearly for technical specialists taking into account the description above and attached drawings. Through example, the articulation device on casters can be modified or eliminated, support being assured against the roof or against the building wall by the base of the T-profile, if lower cost was desired.

    Ces variantes sont simplement données à titre indicatif.These variants are simply given as code.
