Abstract

A scaffolding which, without being dismantled, can be reduced in height to one tenth of its operational height for storage and transportation. The scaffolding comprises platforms (1) with hinged uprights (4) that can be folded to a horizontal position beneath the platforms. Removable guard railings (10) provide bracing. In the storage or transport position, the hinged uprights, the guard railings and optionally the access ladders are housed within the respective platforms (no more than 20 centimetres thick). Said scaffolding can be erected very quickly by extending it using a crane or hoist and locking it in place, and used as a conventional scaffolding, especially a façade scaffolding for the external refurbishment of buildings.

Description

PERFECTIONNEMENT AUX ECHAFAUDAGES HEELIABLES IMPROVEMENT TO HELEL SCAFFOLDING
On connait les échafaudages tubul aires assemblés par colliers, les échafaudages constitués de cadres assemblés entre eux par boulons ou par clavettes, les échafaudages constitués de cadres situés dans des plans verticaux parallèles, assemblés entre eux à l'aide de lisses et de diagonales tubulaires fixées par colliers ou clavettes.We know tubular scaffolding assembled by collars, scaffolding consisting of frames assembled together by bolts or keys, scaffolding consisting of frames located in parallel vertical planes, assembled together using beams and fixed tubular diagonals by necklaces or keys.
Ces différents types d'échafaudages sont longs à mettre en oeuvre car les divers éléments qui les constituent sont stockés séparément au sol et qu'il faut les assembler pièce par pièce en ayant dû au préalable prélever sur le stock les éléments à assembler, les hisser jusqu'à l'emplacement de leur utilisation et les fixer à la portion d'échafaudage déjà construite.These different types of scaffolding take a long time to implement because the various elements which constitute them are stored separately on the ground and they have to be assembled piece by piece having first had to take the elements to be assembled from the stock, hoisting them up to the point of their use and fix them to the portion of scaffolding already built.
La présente invention a pour but de réduire considérablement le temps de montage et la fatigue des monteurs .El le consiste en un échafaudage monté une fois pour toutes, repliable sous un volume réduit pour le stockage et le transport, et qu'il suffit de soulever à la grue ou avec un petit treuil ou un simple palan pour le développer enti rement .Après verrouillage de quelques assemblages, il est prêt à l'emploi. La figure 1 représente en élévation un mode de réalisation possible d'un étage courant, complètement déployé, d'un échafaudage suivant 1 'invention.The object of the present invention is to considerably reduce the assembly time and the fatigue of the assemblers. It consists of a scaffold assembled once and for all, foldable under a reduced volume for storage and transport, and which is sufficient to lift. with the crane or with a small winch or a simple hoist to develop it entirely. After locking a few assemblies, it is ready for use. Figure 1 shows in elevation a possible embodiment of a current stage, fully deployed, of a scaffolding according to one invention.

La figure 12 représente, en élévation,le détail de l'assemblage d'un cadre 26 , d'un tube télescopique 20 et d'un vérin 25 à l'aide des articulations 8 et 9 . La figure 13 est une vue en élévation d'un échafaudage d'étaiement comportant deux étages courants superposés.FIG. 12 shows, in elevation, the detail of the assembly of a frame 26, a telescopic tube 20 and a jack 25 using the joints 8 and 9. Figure 13 is an elevational view of a shoring scaffolding comprising two superimposed current stages.
Dans l'exemple représenté sur les figures 1 et 2 , l'étage courant comporte une passerelle 1 (de préférence métallique, en alliage léger ),dont les flancs 2 assurent la rigidité longitudinale Si besoin est, la rigidité transversale peut être améliorée par l'adjonction de raidisseurs transversaux 3. Cette passerelle 1 est supportée par des "jambes" 4 constituées chacune de deux montants 5 et 6 de même longueur réunis par une articulation centrale 7 formant "genou". Chaque jambe 4 est reliée à la passerelle 1 par une articulation supérieure 8 et à la passerelle la de l'étage immédia¬ tement inférieur par une articulation 9. En position de travail (étage complètement développé), les trois articulations 7 , 8 et 9 sont fermées, les montants 5 et 6 sont parfaitement alignés et les jambes 4 sont en mesure de transmettre les charges verticales sans risque de flambage .En position "stockage" (étage complètement fermé)In the example shown in FIGS. 1 and 2, the current stage comprises a gangway 1 (preferably metallic, made of light alloy), the sides 2 of which provide longitudinal rigidity If necessary, the transverse rigidity can be improved by 'addition of transverse stiffeners 3. This bridge 1 is supported by "legs" 4 each consisting of two uprights 5 and 6 of the same length joined by a central articulation 7 forming "knee". Each leg 4 is connected to the gangway 1 by an upper articulation 8 and to the gangway 1a of the immediately lower stage by a joint 9. In the working position (fully developed stage), the three joints 7, 8 and 9 are closed, the uprights 5 and 6 are perfectly aligned and the legs 4 are able to transmit the vertical loads without risk of buckling. In the "storage" position (stage completely closed)
FEUILLE DE 1 ' articulation 7 est ouverte à 180°, les articulations 8 et 9 sont ouvertes à 90° , de sorte que les montants 5 et 6 qui constituent les jambes, sont repl iés à l 'horizontale entre les deux passerelles 1 et la , comme représenté sur la f igure 3. Lorsque l ' étage courant est complètement dépl oyé, on assurera sa rigidité longitudinale en mettant en place un contreventement approprié comme, par exemple , un cadre rigide 10 broché sur les montants 5 et qui jouera en même temps le rôle de garde-corps . La rigidité transversal e sera assurée par des contreventements appropri és ne gênant pas , s i possible, la circulation sur la passerelle comme , par exemple , des traverses rigides 11 soudées à la partie supérieure des montants 6 et éventuellement renforcées par des goussets 12.SHEET 1 articulation 7 is open at 180 °, joints 8 and 9 are open at 90 °, so that the uprights 5 and 6 which constitute the legs, are folded horizontally between the two gangways 1 and the, as shown in f igure 3. When the current stage is fully deployed, its longitudinal rigidity will be ensured by setting up an appropriate bracing such as, for example, a rigid frame 10 stapled on the uprights 5 and which will play at the same time role of railing. The transverse rigidity e will be ensured by appropriate bracing that does not hinder, if possible, the movement on the gangway such as, for example, rigid sleepers 11 welded to the upper part of the uprights 6 and possibly reinforced by gussets 12.
L ' articulation entre deux montants 5 et 6 représentée àtitre d ' exemple sur la figure 4 , comporte deux platines 13 et 14 respectivement soudées sur les montants 5 et 6. es tronçons de tubes 15 sont alternativement soudés sur les platines 13 et 14 de façon à constituer une charnière munie d'un axe amovible ou non. Cette articulation permet une rotation de 180° des montants 5 et 6 autour de l ' axe 16. En position fermée, les deux platines sont en contact l 'une sur l ' autre et les efforts verticaux sont parfaitement transmis du montant 6 au montant 5. Pour accroitre la sécurité, on peut adjoindre à cette articulation un verrou constitué par exemple par des tronçons de tube 17 soudés alternativement sur les platines 13 et 14, dans lesquels , en position de travail , on introduit une broche amovible 18. On peut également, en variante, sol idariser les montants 5 et 6 par une fermeture à genouillère 19, comme représenté sur la figure 5.The articulation between two uprights 5 and 6 shown as an example in FIG. 4, comprises two plates 13 and 14 respectively welded on the uprights 5 and 6. The sections of tubes 15 are alternately welded on the plates 13 and 14 so to constitute a hinge provided with a removable pin or not. This articulation allows a rotation of 180 ° of the uprights 5 and 6 around the axis 16. In the closed position, the two plates are in contact with one another and the vertical forces are perfectly transmitted from the upright 6 to the upright 5 To increase security, it is possible to add to this articulation a lock constituted for example by sections of tube 17 welded alternately on the plates 13 and 14, into which, in the working position, a removable pin 18 is introduced. alternatively, ground idarize the uprights 5 and 6 by a toggle closure 19, as shown in FIG. 5.
La figure 6 représente un étage courant dont les montants 5 sont munis de rallonges télescopiques , ce qui permet de faire varier la hauteur de l ' étage .Au lieu d' être soudées directement sur les montants 5, les charnières 9 sont soudées sur un tube télescopique 20 percé de trous , qui coulisse dans le montant 5.Une broche 21 solidarise le tube 20 du montant 5 dans la position choisie . L ' étage au sol représenté à titre d' exemple sur la f igure 7 , comporte une passerel le 1 , des montants 6 fixés sous la passerel le 1 par des articulations 8 et des montants 5 articul és sur les montants 6 par des charnières 7. L ' étage au sol étant souvent placé devant des magasins, il est préf érable, dans ce cas, de ne pas assurer la rigidité longitudinale par des cadres 10 mais de préf érence par des diagonales 22 articul ées sur des axes 23 de la passerelle 1 et fixées aux montants 6 par des axes 24. Les montants 5 sont compl étés par des tubes télescopiques 20 munis de vérins de calage 25. L 'absence de c ont revente ment longitudinal entre les montants 5 rend nécessaire un verrouillage positif des articulations 7 en position fermée, verrouillage que l ' on pourra avantageusement réaliser à l 'aide des fermetures à genouillère 19.FIG. 6 represents a current stage, the uprights 5 of which are provided with telescopic extensions, which makes it possible to vary the height of the stage. Instead of being welded directly to the uprights 5, the hinges 9 are welded to a telescopic tube 20 pierced with holes, which slides in the upright 5. A pin 21 secures the tube 20 of the upright 5 in the chosen position. The floor on the ground shown by way of example in f igure 7, includes a gangway 1, uprights 6 fixed under the gangway 1 by joints 8 and uprights 5 articulated on the uprights 6 by hinges 7 The floor on the ground being often placed in front of stores, it is preferable in this case not to ensure longitudinal rigidity by frames 10 but preferably by diagonals 22 articulated on axes 23 of the gangway 1 and fixed to the uprights 6 by pins 24. The uprights 5 are completed by telescopic tubes 20 provided with wedging cylinders 25. The absence of longitudinal resale between the uprights 5 makes it necessary to positively lock the joints 7 in the closed position, locking which can advantageously be achieved using toggle fasteners 19.
L' échafaudage de façade représenté à titre d' exemple sur la figure 8 comporte un étage au sol conforme à celui de la figure 7 et trois étages courants conformes à celui de la figure l.On peut, bien entendu, constituer des échafaudages avec un étage au sol et un nombre quelconque d' étages courants .The facade scaffolding shown by way of example in FIG. 8 comprises a floor on the ground conforming to that of FIG. 7 and three current stages conforming to that of FIG. 1. One can, of course, constitute scaffolding with a floor and any number of common floors.
L ' étage courant d' échafaudage d' étaiement représenté en élévation sur la figure 9, comporte des montants 5 contreventes par cadres amovibles 10 , des montants 6 également contreventes par des cadres 10a et reliés aux montants 5 par des articulations centrales 7 , des tubes télescopiques inf érieurs 20 reliés entre eux par un cadre horizontal inf érieur 26 muni d' articulations 9 et, facultati¬ vement, des vérins 25 articulés sur le cadre horizontal 26 par des charnières 8. Les montants 6 sont prolongés également par des tubes κ Λ télescopiques 20a qui sont rel iés entre eux par un cadre horizontal supérieur 26a par l ' intermédiaire d ' articulations 8a. On peut facultativement rehausser le tout par des vérins à vis 25a articul és sur le cadre horizontal 26a par des charnières 9a. La rigidité transversale est assurée par des contreventements appropriés 27 et 27a comme représenté à titre d' exemple sur la figure 10.The current stage of shoring scaffolding shown in elevation in FIG. 9, comprises uprights 5 braces by removable frames 10, uprights 6 also braced by frames 10a and connected to the uprights 5 by central joints 7, tubes telescopic lower 20 interconnected by a lower horizontal frame 26 provided with joints 9 and, optionally, cylinders 25 articulated on the horizontal frame 26 by hinges 8. The uprights 6 are also extended by tubes κ Λ telescopic 20a which are interconnected by an upper horizontal frame 26a by means of joints 8a. It is optionally possible to enhance the whole by screw jacks 25a articulated on the horizontal frame 26a by hinges 9a. The transverse rigidity is ensured by appropriate braces 27 and 27a as shown by way of example in FIG. 10.
Le cadre 26 représenté à titre d'exemple sur la figure 11, a pour but d' assurer la géométrie horizontale de l ' échafaudage d ' étaiement en reliant entre eux par leurs extrémités les quatre tubes télesco- ques 20.Un cadre 26 comporte essentiellement quatre platines 28 sur lesquelles sont f ixés les contreventements horizontaux 29. haque platine comporte les éléments femelles nécessaires à la réalisation de deux charnières 8 et 9 permettant d'articuler un vérin ou un tube télescopique sous la platine et un tube télescopique ou un vérin sur la platine .The frame 26 shown by way of example in FIG. 11 has the purpose of ensuring the horizontal geometry of the shoring scaffolding by connecting the four telescopic tubes 20 to one another at their ends. A frame 26 essentially comprises four plates 28 on which are fixed the horizontal bracing 29. each plate comprises the female elements necessary for the realization of two hinges 8 and 9 allowing to articulate a jack or a telescopic tube under the plate and a telescopic tube or a jack on platinum .
A titre d' exemple, la figure 12 représente, en él évation, un mode de réalisation possible de 1 ' assemblege , sur la platine d'un cadre 26 de deux tubes télescopiques 20 et 20a. Les tubes télescopiques 20 et 20a sont soudés respectivement sur des platines 30 et 30a. Des tronçons de tube 15 sont alternativement soudés sur la platineBy way of example, FIG. 12 shows, in elevation, a possible embodiment of the assembly, on the plate of a frame 26 of two telescopic tubes 20 and 20a. The telescopic tubes 20 and 20a are welded respectively on plates 30 and 30a. Tube sections 15 are alternately welded to the plate
28 et sur les platines 30 et 30a de façon à réaliser deux charnières munies de deux axes 16 et 16a. Les axes 16 et 16a sont amovibles, de sorte qu ' il est possible, par ce moyen, de fixer rapidement un él ément (tube télescopique ou vérin) sur la platine 28 ou de l 'enlever pour le remplacer par un autre . On peut ainsi aisément, sur un échafaudage déjà construit, ajouter ou enlever un étage courant complet, ajouter ou enlever les vérins .28 and on the plates 30 and 30a so as to produce two hinges provided with two axes 16 and 16a. The axes 16 and 16a are removable, so that it is possible, by this means, to quickly fix an element (telescopic tube or jack) on the plate 28 or to remove it to replace it with another. It is thus easy, on an already built scaffolding, to add or remove a complete running stage, to add or remove the jacks.
L' échafaudage d ' étaiement représenté sur la figure 13 peut ainsi être obtenu à partir de deux échafaudages identiques du type représenté sur la f igure 9 , en enlevant sur le premier les vérins de tête 25a, sur le deuxième les vérins de pied 25 et le cadre 26, et en assemblant le second sur le premier. En choisissant convenablement la l ongueur des tubes téles copiques et celle des vérins à vis , on peut ainsi réaliser, en assemblant des étages courants pré-montés en atel ier et facilement transportables repl iés, des échafaudages d ' étaiement de toutes hauteurs , sans aucune discontinuité.The shoring scaffolding shown in Figure 13 can thus be obtained from two identical scaffolding of the type shown in F igure 9, by removing on the first the cylinders of head 25a, on the second the foot cylinders 25 and the frame 26, and assembling the second on the first. By suitably choosing the length of the telescopic tubes and that of the screw jacks, it is thus possible, by assembling standard pre-assembled workshop floors and easily transportable folded, scaffolding scaffolding of all heights, without any discontinuity.
