DESCRIPTION
La présente invention concerne un dispositif de sustentation, de support & de verrouillage de platelages sur des membrures, contre une paroi verticale possédant ou non des ouvertures,assurant la réalisation d'un échafaudage aérien stable, rigide, modulaire & continu.DESCRIPTION
The present invention relates to a device for supporting, supporting & locking decks on frames, against a vertical wall with or without openings, ensuring the production of a stable, rigid, modular & continuous aerial scaffolding.
Les problèmes d'intervention sur paroi verticale sont généralement résolus au moyen d'échafaudage à partir du bas,de nacelle suspendue ou de plate-forme mise en place au moyen d'engin de levage. The problems of intervention on a vertical wall are generally solved by means of scaffolding from the bottom, suspended gondola or platform set up by means of lifting equipment.
Le dispositif selon l'invention permet de remédier à ces inconvénients en faisant appel à des éléments faciles à manipuler & à mettre en place.I1 comporte en effet selon une première caractéristique deux ou plusieurs membrures latérales de forme circulaire ou elliptique,chacune étant munie d'un bras de sustentation dont l'extrémité libre peut présenter deux formes: - la première,lisse,constitue un axe de pénétration à l'intérieur d'un orifice adéquat - la seconde,en équerre assurant un accrochage des membrures sur ou à travers une paroi.Cette équerre peut prendre la forme d'une platine ou d'un profiléoidentique à celui constitutif des membrures,assemblés par soudure ou de façon mécanique au moyen d'une clavette après encastrement du bras dans la branche secondaire du coude ou dans la platine. The device according to the invention makes it possible to remedy these drawbacks by using elements which are easy to handle & to put in place. It indeed has, according to a first characteristic, two or more lateral members of circular or elliptical shape, each being provided with '' a lifting arm, the free end of which can take two forms: - the first, smooth, constitutes an axis of penetration inside an adequate orifice - the second, at an angle ensuring attachment of the members on or through This wall can take the form of a plate or a profile identical to that constituting the frames, assembled by welding or mechanically by means of a key after embedding the arm in the secondary branch of the elbow or in the platinum.
Les membrures sont réalisées en profilés tubulaires ou non,ouverts, fermés ou pleins,métalliques ou en tout autre matériau adéquat.Le prolongement de ce profilé dans le plan de la membrure constitue le bras de sustentation.The members are made of tubular profiles or not, open, closed or solid, metallic or any other suitable material. The extension of this profile in the plane of the member constitutes the lifting arm.
Les membrures supportent,encastrés sur leur intrados,un ou plusieurs platelages caractérisés par trois nervures longitudinales en forme de V ou de goulotte dont la section présente une conicité longitudinale selon un angle inférieur à un degré,de façon à assurer l'embottement des platelages par leur extrémité sur une longueur suffisante pour assurer une continuité mécanique.The frames support, embedded on their lower surface, one or more decks characterized by three longitudinal ribs in the shape of a V or a trough whose section has a longitudinal conicity at an angle less than one degree, so as to ensure the embedding of the decks by their end over a length sufficient to ensure mechanical continuity.
Les deux nervures latérales assurent le coulissement d'une tringle qui verrouille le dispositif après encastrement.The two lateral ribs ensure the sliding of a rod which locks the device after installation.
Les dessins annexés illustrent l'invention:
La figure 1 représente,en coupe suivant le plan de la membrure, le dispositif selon l'invention.The accompanying drawings illustrate the invention:
Figure 1 shows, in section along the plane of the frame, the device according to the invention.
La figure 2 représente,en coupe suivant un plan perpendiculaire au précédent,l'intersection par encastrement d'une nervure latérale d'un platelage avec la membrure.Figure 2 shows, in section along a plane perpendicular to the previous one, the intersection by embedding a lateral rib of a deck with the member.
La figure 3 représente,à une échelle plus petite,les détails du positionnement d'un platelage sur la membrure.Figure 3 shows, on a smaller scale, the details of the positioning of a deck on the frame.
En référence à ces dessins, le dispositif comporte deux ou plusieurs membrures (l)latérales de forme circulaire munies d'un bras (2)de sustentation dont la lonqueur détermine l'épaisseur maximum de la paroi d'appui. With reference to these drawings, the device comprises two or more lateral members (l) of circular shape provided with a support arm (2), the length of which determines the maximum thickness of the support wall.
Cette forme circulaire permet de positionner le platelage (3)
servant de plate-forme dans un plan horizontal quel que soit l'angle formé par le bras de sustentation (2)avec le plan de la paroi,c' est à dire quelle que soit l'épaisseur de cette paroi dans la limite de la longueur du bras (2).I1 en est de même pour tout autre platelage (3) qui serait par exemple situé dans un plan orthogonal au précédents assurerait la sécurité arrière du dispositif.This circular shape makes it possible to position the decking (3)
serving as a platform in a horizontal plane whatever the angle formed by the lifting arm (2) with the plane of the wall, that is to say whatever the thickness of this wall within the limit of the length of the arm (2) .I1 is the same for any other decking (3) which would be for example located in a plane orthogonal to the previous would provide rear safety of the device.
Les platelages (3) reposent sur l'intrados des membrures (1) par trois surfaces de contact différentes: - une première constituée par une nervure médiane longitudinale (5) - une deuxième constituée par deux nervures latérales longitudinales (4) encochées à leur point d'intersection avec les membrures (1) de telle sorte que l'encastrement (4)des premières sur ces dernières s'effectue sans problème.A cet effet,la largeur des encoches correspond à la section du profilé constitutif des membrures (l),leur profondeur est égale à cette même section augmentée de l'épaisseur d'une tringle en acier. The plates (3) rest on the lower surface of the members (1) by three different contact surfaces: - a first formed by a longitudinal central rib (5) - a second formed by two longitudinal lateral ribs (4) notched at their point intersection with the members (1) so that the embedding (4) of the first on the latter is carried out without problem. For this purpose, the width of the notches corresponds to the section of the profile constituting the members (l) , their depth is equal to this same section increased by the thickness of a steel rod.
Cette tringle (6) coulisse dans le fond de la gorge de chaque nervure dont la section transversale a une forme de goulotte ou de V,de telle sorte qu'après encastrement,elle prenne appui sur le fond de la gorge des nervures de part & d'autre de l'en- coche, bloquant ainsi 1' extrados des membrures (l).Pour faciliter le coulissement & la mise en place de ces tringles (6),leurs extrémités sont reliées deux à deux par une traverse en forme(7) de poignée en bout de platelage (3).This rod (6) slides in the bottom of the groove of each rib, the cross section of which has a trough or V shape, so that after embedding, it rests on the bottom of the groove of the ribs on the side & on the other side of the notch, thus blocking the upper surface of the members (1). To facilitate the sliding & the positioning of these rods (6), their ends are linked in pairs by a cross-shaped ( 7) handle at the end of the decking (3).
- une troisième constituée par deux ailes (8) extérieures & BR< adjacentes aux nervures latérales (4),qui s'inscrivent dans la courbure de l'intrados des membrures (1) par un arrondi de leur profil transversal.- A third consisting of two wings (8) outside & BR <adjacent to the side ribs (4), which are part of the curvature of the underside of the members (1) by a rounded transverse profile.
Le blocage au moyen de la tringle (6) des platelages (3) sur les membrures (1) au niveau des encastrements rigidifie le dispositif.Celui-ci est complètement verrouillé & devient monobloc lorsque ce blocage s'effectue sur deux platelages disposés dans deux plans orthogonaux encastrés sur deux membrures (1) paral lèles.0n obtient ainsi le module répétitif d'un échafdage aérien stable, rigide & continu. The blocking by means of the rod (6) of the plates (3) on the frames (1) at the level of the recesses stiffens the device. This is completely locked & becomes monoblock when this blocking is carried out on two plates arranged in two orthogonal planes embedded on two parallel frames (1). 0n thus obtains the repetitive module of a stable, rigid & continuous aerial scaffolding.
L'accrochage du dispositif sur la paroi se fait au moyen du bras (2) de sustentation qui peut être équipé d'un coude offrant quatre variantesf 9): - par soudage à 900 à l'extrémité lisse du bras (2) d'une platine ou d'un élément de profilé constitutif de la membrure (1) - par assemblage mécanique d'un élément de profilé ou d'une platine munis d'une lumière permettant le passage du bras (2)qui sera bloqué dans cette position par une clavette. The device is attached to the wall by means of the lifting arm (2) which can be fitted with an elbow offering four variants (9): - by welding at 900 to the smooth end of the arm (2) d a plate or of a profile element constituting the frame (1) - by mechanical assembly of a profile element or a plate provided with a light allowing the passage of the arm (2) which will be locked in this position by a key.
