Description
Echafaudage à structure simplifiéeSimplified structure scaffolding
L'invention concerne un échafaudage à structure simplifiée et notamment pour son cadre d'embase. The invention relates to a scaffolding with a simplified structure and in particular for its base frame.
Les échafaudages classiques comportent un cadre d'embase support des rallonges verticales, constitué généralement par un parallélogramme articulé, lequel est verrouillé dans une forme rectangulaire d'embase de service. Ces embases sont complexes, lourdes, spécifiques à chaque gabarit d'échafaudage et relativement onéreuses. Conventional scaffolding comprises a base frame supporting vertical extensions, generally constituted by an articulated parallelogram, which is locked in a rectangular shape of service base. These bases are complex, heavy, specific to each scaffolding template and relatively expensive.
L'invention vise à remédier à ces inconvénients et propose un échafaudage à structure simplifiée, notamment pour son cadre d'embase, comprenant deux jeux opposés de rallonges verticales disposées l'une sur l'autre à la hauteur désirée et pourvues chacune d'échelons horizontaux, caractérisé en ce qu'il comporte au moins une 15 barre rigide, laquelle est pourvue à chacune de ses extrémités d'un crochet apte à s'engager à faible jeu sur un échelon de rallonge au niveau d'un des montants, et d'un plat arrière rigide attenant au crochet et destiné à s'appliquer à faible jeu sur le montant, de part et d'autre de l'échelon, lequel est engagé à la barre rigide pour la relier 20 perpendiculairement au plan de la rallonge, et au moins une barre diagonale disposée de l'autre côté de la barre rigide et reliant les deux jeux de rallonges verticales, l'un à l'autre, la barre rigide étant apte à être disposée au niveau inférieur des rallonges pour constituer l'embase support de celles-ci. The invention aims to remedy these drawbacks and proposes a scaffolding with a simplified structure, in particular for its base frame, comprising two opposite sets of vertical extensions placed one on the other at the desired height and each provided with steps horizontal, characterized in that it comprises at least one rigid bar, which is provided at each of its ends with a hook capable of engaging with little play on an extension rung at the level of one of the uprights, and of a rigid rear plate adjoining the hook and intended to be applied with slight play on the upright, on either side of the rung, which is engaged with the rigid bar to connect it perpendicular to the plane of the extension , and at least one diagonal bar arranged on the other side of the rigid bar and connecting the two sets of vertical extensions, one to the other, the rigid bar being able to be arranged at the lower level of the extensions to constitute the 'emb ase support of these.
L'échafaudage comporte de préférence deux barres rigides disposées chacune de chaque côté de l'échafaudage, au niveau inférieur, ce qui rigidifie l'embase support des rallonges. Dans ce cas et pour de faibles hauteurs d'échafaudage la ou les barres diagonales d'équerrage de rallonges sur l'embase peuvent être supprimée(s), 30 l'équerrage vertical étant assuré de chaque côté par les plats des barres appliqués sur les montants de rallonges. The scaffolding preferably comprises two rigid bars each disposed on each side of the scaffolding, at the lower level, which stiffens the support base of the extensions. In this case and for low scaffolding heights, the diagonal rod or bars for squaring out extensions on the base can be omitted, the vertical squaring being provided on each side by the flat bars applied on the amounts of extensions.
Les deux barres rigides peuvent être reliées l'une à l'autre dans un même plan horizontal de l'échafaudage, selon un cadre rectangulaire, par au moins une barre de traverse solidarisée par ses extrémités à 35 chaque barre et, de préférence, par deux barres de traverse opposées, disposées chacune au niveau des extrémités des barres rigides. The two rigid bars can be connected to each other in the same horizontal plane of the scaffolding, according to a rectangular frame, by at least one cross bar joined at its ends to each bar and, preferably, by two opposite cross bars, each arranged at the ends of the rigid bars.
Dans cette structure d'embase simplifiée de l'échafaudage, des roulettes peuvent être montées à l'extrémité inférieure des tubes de rallonge, ces roulettes étant de préférence montées chacune sur un bras support constitué d'un tube emmanché verrouillé en position de service 5 sur la partie d'extrémité du tube de rallonge. Ces bras supports peuvent être inclinés vers l'extérieur en service de façon à stabiliser l'échafaudage en hauteur et éventuellement ramenés chacun vers l'intérieur en le tournant sur le tube de montant en position escamotée pour le roulement de l'échafaudage en passage étroit. In this simplified base structure of the scaffolding, rollers can be mounted at the lower end of the extension tubes, these rollers being preferably each mounted on a support arm consisting of a fitted tube locked in the service position 5 on the end part of the extension tube. These support arms can be inclined towards the outside in service so as to stabilize the scaffolding in height and possibly brought each inwards by turning it on the upright tube in the retracted position for the rolling of the scaffolding in narrow passage .
Naturellement, l'échafaudage de l'invention comporte un plateau supérieur dont la structure peut également être formée par deux barres rigides latérales du type de celle de l'embase et portant un plan support de charge. Naturally, the scaffolding of the invention comprises an upper plate, the structure of which can also be formed by two rigid lateral bars of the type of that of the base and carrying a load support plane.
L'invention est à présent décrite à l'aide d'un exemple de 15 réalisation et en référence aux dessins annexés, sur lesquels: - La fig. 1 est une vue en perspective d'un échafaudage selon l'invention, et - La fig. 2 est une vue partielle agrandie de la figure 1 montrant la liaison des barres rigides de l'embase aux montants des 20 rallonges. The invention is now described with the aid of an exemplary embodiment and with reference to the accompanying drawings, in which: - FIG. 1 is a perspective view of a scaffolding according to the invention, and - FIG. 2 is an enlarged partial view of FIG. 1 showing the connection of the rigid bars of the base to the uprights of the extensions.
L'échafaudage représenté comporte essentiellement un cadre d'embase 1 support de deux jeux 3 de rallonges verticales 5, un plateau 7 support de charges supérieur et des éléments de roulettes inférieurs 9. The scaffolding shown essentially comprises a base frame 1 support for two sets 3 of vertical extensions 5, a plate 7 upper load support and lower roller elements 9.
Les jeux de rallonges 3 sont constitués chacun de deux rallonges métalliques 5 emmanchées l'une sur l'autre par l'extrémité attenante de leurs montants tubulaires 11. Ces rallonges 5 comportent des échelons tubulaires horizontaux 13 disposés régulièrement à hauteur et par lesquels le plateau support de charge est porté, solidarisé par 30 crochetage de ses extrémités à deux échelons correspondants des jeux de rallonges à la hauteur de service souhaitée. The sets of extensions 3 each consist of two metal extensions 5 fitted one on the other by the adjoining end of their tubular uprights 11. These extensions 5 include horizontal tubular steps 13 regularly arranged at height and by which the plate load support is carried, secured by hooking its ends to two corresponding steps of sets of extensions at the desired service height.
Les éléments à roulette 9 comportent chacun un bras tubulaire incliné 15, courbé vers l'extérieur et dont l'extrémité supérieure est emmanchée dans l'extrémité inférieure correspondante des montants 35 tubulaires 1 1 de rallonge. En service, ils sont verrouillés par goupillage en extension latérale, parallèlement au plan de rallonge et ils peuvent être ramenés tournés, après dégoupillage, vers l'intérieur pour permettre le roulement de l'échafaudage dans des passages étroits (de The roller elements 9 each comprise an inclined tubular arm 15, curved outwards and the upper end of which is fitted into the corresponding lower end of the tubular uprights 1 1 of extension. In service, they are locked by pinning in lateral extension, parallel to the extension plane and they can be brought back turned, after uncoupling, inwards to allow the scaffolding to roll in narrow passages (from
porte par exemple).door for example).
Le cadre d'embase 1 est constitué de deux barres rigides 17 solidarisées latéralement et par chacune de leurs extrémités à la partie 5 inférieure des rallonges. Ces barres rigides 17 comportent en effet à leur extrémité un élément de crochet 19 par lequel elles peuvent être engagées crochetées sur l'échelon inférieur 13 de rallonge, au droit du montant 1 1 de rallonge. Cet élément de crochet est constitué par un doigt de crochet 21 tourné vers le bas verticalement à l'intérieur du 10 montant, d'un plat arrière 23 s'étendant sur une certaine longueur de part et d'autre de l'échelon et contre la partie arrière du montant 11, d'une virgule 25 de verrouillage du crochetage articulée à la partie supérieure du doigt 21 et tombant naturellement par gravité en retenue sous l'échelon 13, et d'un pli latéral 27 externe parallèle au doigt de 15 crochet, d'une seule pièce avec le plat arrière et revenant contre le montant. Le doigt 21 reçoit à faible jeu l'échelon au niveau de sa partie d'extrémité tandis que le plat 23 s'applique contre le montant à l'arrière pour maintenir la barre 17 perpendiculairement au plan de la rallonge. The base frame 1 consists of two rigid bars 17 secured laterally and by each of their ends to the lower part 5 of the extensions. These rigid bars 17 in fact have at their end a hook element 19 by which they can be engaged hooked on the lower rung 13 of extension, in line with the upright 1 1 of extension. This hook element is constituted by a hook finger 21 turned vertically inside the upright, of a rear plate 23 extending over a certain length on either side of the rung and against the rear part of the upright 11, a comma 25 for locking the hooking articulated to the upper part of the finger 21 and falling naturally by gravity into retention under the rung 13, and of an external lateral fold 27 parallel to the finger of 15 hook, in one piece with the rear plate and returning against the upright. The finger 21 receives the step at low clearance at its end portion while the flat 23 is applied against the upright at the rear to keep the bar 17 perpendicular to the plane of the extension.
On notera que le doigt peut comporter une rampe d'engagement 29 20 conique autobloquante légèrement inclinée vers l'extérieur et permettant le blocage sans jeu de la barre sur l'échelon par simple choc, par un coup de marteau sur le plat par exemple, et sans besoin d'une virgule de verrouillage. It will be noted that the finger may comprise a self-locking conical engagement ramp 29 20 slightly inclined towards the outside and allowing blocking without play of the bar on the rung by simple impact, by a hammer blow on the dish for example, and without the need for a locking comma.
Le montage de l'échafaudage est très simple. Il suffit de monter les 25 deux barres d'embase 17 sur chacune des rallonges inférieures des deux jeux, successivement en crochetant latéralement l'échelon inférieur. On monte ensuite les éléments à roulettes 9 en enfilant l'extrémité du bras 15 dans le tube des montants 1 1 et en goupillant pour verrouiller en extension latérale. On monte alors les jeux de 30 rallonge en disposant les rallonges l'une sur l'autre par emmanchement des montants correspondants des rallonges l'une sur l'autre, jusqu'à la hauteur souhaitée; On monte enfin le plateau support de charges 7. The assembly of the scaffolding is very simple. It suffices to mount the two base bars 17 on each of the lower extensions of the two sets, successively by laterally hooking the lower rung. The roller elements 9 are then mounted by threading the end of the arm 15 into the tube of the uprights 11 and by pinning to lock in lateral extension. The sets of extension pieces are then mounted by placing the extensions one on the other by fitting the corresponding amounts of the extensions one on the other, to the desired height; Finally, the load support plate 7 is mounted.
Eventuellement selon la hauteur de l'échafaudage, on peut relier les jeux de rallonge par des barres diagonales (non représentées) rigidifiant 35 l'équerrage en hauteur des rallonges sur l'embase. Optionally, depending on the height of the scaffolding, the extension sets can be connected by diagonal bars (not shown) stiffening the squareness in height of the extensions on the base.
Le démontage est obtenu de manière inverse au montage. Disassembly is obtained in reverse to assembly.
