Description

L'invention concerne un dispositif de suspension d'une nacelle d'échafaudage.The invention relates to a device for suspending a scaffolding nacelle.

Pour les immeubles présentant un toit en terasse, il est connu de suspendre la nacelle d'un échafaudage au moyen d'une chèvre fixée sur l'acrothère, en haut de la façade, et maintenue par un câble de sécurité, par exemple attaché autour d'une cheminée ou portant un contrepoids pendant devant la façade opposée de l'immeuble.For buildings with a terraced roof, it is known to suspend the nacelle from scaffolding by means of a goat fixed on the acrothère, at the top of the facade, and maintained by a security cable, for example tied around a chimney or carrying a counterweight hanging in front of the opposite facade of the building.

En général, une telle chèvre permet de placer la nacelle 30 cm environ de la façade. Lorsque la façade comporte des balcons, la nacelle ne peut être disposée de façon stable en face des balcons, et il est nécessaire de prévoir un autre système de suspension de la nacelle.In general, such a goat allows the basket to be placed about 30 cm from the front. When the facade has balconies, the nacelle cannot be arranged stably in front of the balconies, and it is necessary to provide another system for suspending the nacelle.

Par ailleurs, la fixation du câble de sécurité n'est pas toujours simple autour d'un bloc de cheminées, et la mise en place du contrepoids au dessus du videprésente des risques de chute.Furthermore, fixing the safety cable is not always simple around a block of chimneys, and the installation of the counterweight above the vacuum presents risks of falling.

L'un des buts de l'invention et de prévoir un dispositif de suspension d'une nacelle susceptible de supporter la nacelle aussi bien en face des parties nues de la façade qu'en face des balcons.One of the aims of the invention and to provide a device for suspending a nacelle capable of supporting the nacelle both in front of the bare parts of the facade and in front of the balconies.

Un autre but de l'invention est de prévoir un organe de fixation du câble de sécurité qui n'exige pour sa mise en place qu'une surface plane minime et parallèle la façade.Another object of the invention is to provide a member for fixing the safety cable which requires for its installation only a minimal flat surface and parallel to the facade.

L'invention a pour objet un dispositif de suspension d'une nacelle d'échafaudage, du type comportant un ensemble fixé sur l'acrothère en haut de la façade d'un immeuble et un câble de sécurité tendu sur la terrasse de l'immeuble pour retenir ledit ensemble, caractérisé en ce qu'il comporte :
- un cadre rigide appliqué contre la façade et porté par des bras reposant sur l'acrothère, et
- un portique en triangle isocèle articulé par sa base sur la partie la plus basse du cadre pour prendre différentes inclinaisons par rapport à la façade, correspondant à différentes distances entre la façade et la nacelle;
- le sommet du portique triangulaire étant retenu par le câble de sécurité.The subject of the invention is a device for suspending a scaffolding nacelle, of the type comprising an assembly fixed to the acrothère at the top of the facade of a building and a security cable stretched over the terrace of the building to retain said assembly, characterized in that it comprises:
- a rigid frame applied against the facade and carried by arms resting on the acrothère, and
- an isosceles triangle portico articulated by its base on the lowest part of the frame to take different inclinations with respect to the facade, corresponding to different distances between the facade and the nacelle;
- the top of the triangular gantry being retained by the safety cable.

Selon d'autres caractéristiques de l'invention :
- Le cadre est constitué de deux montants verticaux et de deux traverses horizontales.
- Les montants portent deux prolongements s'étendant vers le haut pour la mise en place du dispositif.
- Les bras reposant sur l'acrothère sont rabattables vers le bas sur les montants.
- La traverse la plus basse du cadre est légèrement décalée vers l'extérieur pour permettre le rabattement du portique contre le cadre en vue du stockage plat du dispositif.
- Sur les bras est fixé un câble passant au dessus du câble de sécurité pour lui donner une direction pratiquement constante vers l'arrière quelle que soit l'inclinaison du portique.
-Le câble de sécurité porte à son extrémité un crochet d'ancrage derrière une surface parallèle à la façade.
- Le crochet d'ancrage présente une pointe portant une bille tenue dans une coupelle pour constituer une articulation à rotule.
-La coupelle est solidaire d'une plaque portant sur sa face opposée à la coupelle des tampons antidérapants.
-Le crochet d'ancrage est en réseau et constitué de tiges métalliques en forme de crochet, reliées ensemble à leurs extrémités et munies d'entretoises réparties.According to other characteristics of the invention:
- The frame consists of two vertical uprights and two horizontal crosspieces.
- The uprights carry two extensions extending upward for the installation of the device.
- The arms resting on the acrothère can be folded down on the uprights.
- The lowest cross member of the frame is slightly offset towards the outside to allow the gantry to fold down against the frame for flat storage of the device.
- A cable is attached to the arms passing over the safety cable to give it a practically constant rearward direction whatever the inclination of the gantry.
-The safety cable carries at its end an anchoring hook behind a surface parallel to the facade.
- The anchoring hook has a point carrying a ball held in a cup to constitute a ball joint.
-The cup is secured to a plate carrying on its face opposite to the cup non-slip pads.
-The anchor hook is a network and consists of metal rods in the form of a hook, connected together at their ends and provided with distributed spacers.

D'autres caractéristiques ressortent de la description qui suit faite avec référence au dessin annéxé sur lequel on peut voir :

  • - Fig. 1 : une vue perspective du dispositif de suspension d'une nacelle d'échafaudage selon l'invention;
  • - Fig. 2 : une vue perpendiculaire au plan de la façade montrant deux positions possibles de l'organe en V de suspension de la nacelle, selon l'invention;
  • - Flg. 3 : une vue agrandie de l'organe de fixation du câble de sécurité, selon l'invention.
Other characteristics appear from the following description made with reference to the appended drawing on which we can see:
  • - Fig. 1: a perspective view of the suspension device for a scaffolding nacelle according to the invention;
  • - Fig. 2: a view perpendicular to the plane of the facade showing two possible positions of the V-shaped member for suspending the nacelle, according to the invention;
  • - Flg. 3: an enlarged view of the security cable fixing member according to the invention.

En se reportant à la Fig. 1, on peut voir un immeuble 1 présentant une façade 2 et une façade opposée 3. Pour suspendre une nacelle devant la façade 2, le dispositif de suspension selon l'invention est diposé sur l'acrothère 4 bordant la terrasse de l'immeuble 1. Ce dispositif de suspension comporte un cadre vertical constitué de deux montants verticaux 5,6 et de deux traverses horizontales 7,8.Referring to FIG. 1, we can see a building 1 having a facade 2 and an opposite facade 3. To suspend a nacelle in front of the facade 2, the suspension device according to the invention is placed on the acrothère 4 bordering the terrace of the building 1 This suspension device comprises a vertical frame consisting of two vertical uprights 5,6 and two horizontal crosspieces 7,8.

La traverse 7 est placée à l'arête supérieure de l'acrothère 4 et la traverse 8, contre la façade 2. Les montants verticaux 5,6 sont appliqués sur la façade 2 mais ils présentent un prolongement 9, 10, qui fait saillie au dessus de l'acrothère 4. Ces prolongements 9, 10 servent pour la manutention et la mise en place du dispositif de suspension.The cross member 7 is placed at the upper edge of the acrothere 4 and the cross member 8, against the facade 2. The vertical uprights 5, 6 are applied to the facade 2 but they have an extension 9, 10, which projects at the above the acrothere 4. These extensions 9, 10 are used for handling and positioning the suspension device.

Pour maintenir le dispositif de suspension sur l'acrothère 4, deux bras 11 et 12 sont disposés perpendiculairement au plan du cadre 5-8 et vers l'arrière, de façon reposer sur l'acrothère 4.To hold the suspension device on the acrothère 4, two arms 11 and 12 are arranged perpendicular to the plane of the frame 5-8 and towards the rear, so as to rest on the acrothère 4.

Le dispositif de suspension comporte encore un portique en triangle isocèle dont la base tourillonne sur la traverse 8 du cadre, par exemple, et dont les deux côtés égaux 13, 14 se rejoignent au sommet 15. Ce portique est maintenu dans la position voulue par un câble de sécurité 16 dont une extrémité est fixée au sommet 15 du triangle et dont l'autre extrémité porte un crochet d'ancrage 17. Ce crochet d'ancrage 17 est appliqué derrière une surface plane parallèle à la façade 2. Pour assurer un ancrage satisfaisant (Fig 3), la pointe du crochet 17 porte une bille 18 qui est tenue dans une coupelle 19 pour constituer une articulation à rotule. La coupelle est portée par une plaque 20 présentant de préférence sur sa surface opposée à la coupelle 19 des tampons antidérapants 21, par exemple au nombre de quatre.The suspension device also includes an isosceles triangle gantry, the base of which swivels on the cross-member 8 of the frame, for example, and the two equal sides 13, 14 of which meet at the top 15. This gantry is held in the desired position by a safety cable 16, one end of which is fixed to the top 15 of the triangle and the other end of which carries an anchoring hook 17. This anchoring hook 17 is applied behind a flat surface parallel to the facade 2. To ensure anchoring satisfactory (Fig 3), the tip of the hook 17 carries a ball 18 which is held in a cup 19 to form a ball joint. The cup is carried by a plate 20 preferably having on its surface opposite to the cup 19 non-slip pads 21, for example four in number.

De cette manière, la plaque 20 est appliquée derrière une surface parallèle à la façade, par exemple un bloc de cheminée, une cloison ou l'acrothère de la façade opposée 3 de l'immeuble. Les tampons 21 assurent le maintien en position de la plaque 20 et de la pointe du crochet 17. La tension du câble 16, qui peut être réglée manuellement au moyen d'un tendeur à friction de type classique, assure le maintien en position relative du crochet 17 et du portique.In this way, the plate 20 is applied behind a surface parallel to the facade, for example a chimney block, a partition or the acrothère of the opposite facade 3 of the building. The pads 21 maintain the plate 20 and the tip of the hook 17. The tension of the cable 16, which can be adjusted manually by means of a friction tensioner of conventional type, ensures that the hook 17 and the gantry are held in relative position.

Sur la Fig. 2, on voit que le sommet 15 du portique porte la nacelle 22. Le dessin a été simplifié, mais la suspension de la nacelle 22 est de type classique : le sommet 15 du portique porte un moufle de palan dont l'autre moufle est au sommet de la nacelle. L'opérateur qui est sur la nacelle peut aussi commander les mouvements verticaux de la nacelle.In Fig. 2, we see that the top 15 of the gantry carries the nacelle 22. The drawing has been simplified, but the suspension of the nacelle 22 is of conventional type: the top 15 of the gantry carries a hoist block, the other block of which is at top of the basket. The operator who is on the platform can also control the vertical movements of the platform.

Sur la Fig. 2, on voit que le portique peut prendre plusieurs positions correspondant à des inclinaisons différentes sur la façade 2. La position représentée en trait plein correspond à la position de la nacelle 22 prévue pour le travail sur la façade nue. La position en trait interrompu correspond à la position de la nacelle 22′ prévue pour le travail au delà des balcons. Dans cette position, le sommet 15′ du portique en triangle est nettement plus éloigné de la façade.In Fig. 2, we see that the gantry can take several positions corresponding to different inclinations on the facade 2. The position shown in solid lines corresponds to the position of the nacelle 22 provided for work on the bare facade. The dashed line position corresponds to the position of the nacelle 22 ′ provided for work beyond the balconies. In this position, the vertex 15 ′ of the triangle gantry is much further from the facade.

Pour éviter que le crochet 17 ne soit soumis à des contraintes nettement différentes en fonction des positions de la nacelle par rapport à la façade, il peut paraître souhaitable de donner au câble 16 une orientation pratiquement constante quelle que soit la position du sommet 15 du portique. A cet effet, on peut placer entre les bras 11 et 12, au voisinage de leur articulation sur les montants 5 et 6, un câble 23 passant au dessus du câble 16 et qui, sous la tension du câble 16, prendra une position d'équilibre représentée sur la Fig. 2. De cette manière, entre le crochet 17 et son point de passage sous le câble 23, le câble 16 gardera sensiblement la même position pour des positions du sommet du portique variant de 15 à 15′.To prevent the hook 17 from being subjected to clearly different stresses depending on the positions of the nacelle relative to the facade, it may seem desirable to give the cable 16 an almost constant orientation whatever the position of the top 15 of the gantry . For this purpose, one can place between the arms 11 and 12, in the vicinity of their articulation on the uprights 5 and 6, a cable 23 passing over the cable 16 and which, under the tension of the cable 16, will assume a position of balance shown in Fig. 2. In this way, between the hook 17 and its point of passage under the cable 23, the cable 16 will keep substantially the same position for positions of the top of the gantry varying from 15 to 15 ′.

En se reportant à la Fig. 3, on peut voir un mode de réalisation particulier du crochet 17. Ce crochet doit être de grandes dimensions pour être d'un usage pratique. Il faut en conséquence qu'il soit de structure légère.Referring to FIG. 3, we can see a particular embodiment of the hook 17. This hook must be large to be of practical use. It must therefore be of light structure.

Dans l'exemple représenté, le crochet est en réseau et constitué de trois tiges métalliques 24, 25, 26 chacune en forme de crochet, reliées ensemble d'une part à la pointe du crochet 17, d'autre part à la base 27 du crochet 17. Les tiges 24 et 26 sont disposées symétriquement par rapport au plan contenant la tige 25. Des entretoises telles que 28 et 29 sont disposées entre d'une part la tige 25 et d'autre part les tiges 24 et 26 respectivement. Ces entretoises sont réparties depuis la pointe du crochet 17 jusqu'à sa base 27. Cette base se termine par une oeil 30 dans lequel passe la câble 16.In the example shown, the hook is in a network and consists of three metal rods 24, 25, 26 each in the form of a hook, connected together on the one hand to the tip of the hook 17, on the other hand to the base 27 of the hook 17. The rods 24 and 26 are arranged symmetrically with respect to the plane containing the rod 25. Spacers such as 28 and 29 are arranged between on the one hand the rod 25 and on the other hand the rods 24 and 26 respectively. These spacers are distributed from the tip of the hook 17 to its base 27. This base ends with an eye 30 through which the cable 16 passes.

Avantageusement, les bras 11 et 12 sont articulés sur les montants 5 et 6 de façon à pouvoir être rabattus contre ces montants en position de stockage et à être stables perpendiculairement à ces montants dans la position de travail représentée au dessin. De cette manière, l'ensemble du dispositif de suspension de la nacelle peut être stocké à plat, avec les bras 11, 12 rabattus et le portique triangulaire relevé jusqu'à être pratiquement dans le plan du cadre 5-8. On peut même prévoir de décaler légèrement la traverse 8 du cadre vers l'extérieur de façon que le portique se replie dans un plan parallèle au cadre.Advantageously, the arms 11 and 12 are articulated on the uprights 5 and 6 so as to be able to be folded against these uprights in the storage position and to be stable perpendicular to these uprights in the working position shown in the drawing. In this way, the entire suspension device of the nacelle can be stored flat, with the arms 11, 12 folded down and the triangular gantry raised until it is practically in the plane of the frame 5-8. One can even provide for slightly shifting the cross member 8 of the frame outward so that the gantry folds in a plane parallel to the frame.
