Abstract
Description
La présente invention concerne un nouveau dispositif pour décaper les façades avant d'effectuer un ravalement. The present invention relates to a new device for stripping facades before carrying out a facelift.
Il est en effet nécessaire d'enlever totalement un revêtement existant lorsque l'on veut en appliquer un nouveau. It is indeed necessary to completely remove an existing coating when one wants to apply a new one.
Usuellement, on utilise une lame pour soulever le revêtement après avoir chauffé celui-ci à l'aide d'un chalumeau. Une telle utilisation de deux outils différents nécessite soit la présence de deux ouvriers au même endroit du chantier, soit si un seul ouvrier est présent qu'il tienne tour à tour chacun des outils ou qu'il en prenne un dans chaque main. Usually, a blade is used to lift the coating after having heated it using a blowtorch. Such use of two different tools requires either the presence of two workers at the same location on the site, or if only one worker is present, he holds each of the tools in turn or takes one in each hand.
Si l'on met deux ouvriers sur le même poste, on comprend aisément que la main oeuvre coûtera très cher lors d'une opération de décapage. If you put two workers on the same station, you can easily understand that labor will be very expensive during a stripping operation.
Si un seul ouvrier est chargé du poste alors il aura peu de force pour appuyer sur la lame s'il tient celle-ci d'une seule main. If only one worker is responsible for the job then he will have little force to press on the blade if he holds it with one hand.
Si par contre, il prend tour à tour le chalumeau et la lame alors le revêtement aura trop refroidi pour être facilement enlevé durant le temps nécessaire pour poser le chalumeau et reprendre la lame. If, on the other hand, it takes the torch and the blade in turn, then the coating will have cooled too much to be easily removed during the time necessary to lay the torch and take up the blade.
La présente invention propose donc de pallier ces différents inconvénients en proposant un nouveau dispositif de décapage qui soit efficace et facilement utilisable par une seule personne. The present invention therefore proposes to overcome these various drawbacks by proposing a new stripping device which is effective and easily usable by a single person.
A cet effet, le dispositif pour décaper les façades selon l'invention est caractérisé en ce qu'il comporte sur un manche, une lame destinée à décoller le revêtement à enlever et des moyens de chauffage dudit revêtement, agissant au voisinage de la lame. To this end, the device for stripping the facades according to the invention is characterized in that it comprises on a handle, a blade intended to peel off the coating to be removed and means for heating said coating, acting in the vicinity of the blade.
L'invention est également avantageuse en ce que
- lesdits moyens de chauffage comportent au moins un brûleur
- le brûleur est positionné au dessus de la lame et orienté de manière à chauffer ce qui se trouve à l'avant de cette lame
- un second brûleur est prévu et disposé afin de chauffer une surface située à côté de la lame
- les moyens de chauffage sont maintenus en place par une plaque support fixée sur le manche
- une extrémité du manche est conformée en poignée comportant un levier de modification du débit de gaz dans le tuyau d' alimentation des brûleurs
- un pontet est prévu afin de pouvoir accrocher le dispositif à un câble.The invention is also advantageous in that
- Said heating means comprise at least one burner
- the burner is positioned above the blade and oriented so as to heat what is at the front of this blade
- a second burner is provided and arranged to heat a surface located next to the blade
- the heating means are held in place by a support plate fixed on the handle
- one end of the handle is shaped as a handle comprising a lever for modifying the gas flow rate in the burner supply pipe
- a trigger guard is provided in order to be able to hang the device on a cable.
La présente invention sera mieux comprise à 1' aide de la description qui va suivre d' un exemple de réalisation de celle-ci en référence au dessin dans lequel
- la figure 1 est une vue de côté du dispositif selon l'invention lf invention
- la figure 2 est une vue de dessus du dispositif selon l'invention.The present invention will be better understood with the aid of the description which follows of an embodiment thereof with reference to the drawing in which
- Figure 1 is a side view of the device according to the invention lf invention
- Figure 2 is a top view of the device according to the invention.
Sur les figures on voit en 1 le manche permettant de tenir fermement le dispositif selon 1' invention. In the figures we see in 1 the handle for firmly holding the device 1 according to the invention.
A l'une de ses extrémités, ledit manche 1 est conformé en poignée 2 cornportant un levier 3 de commande d'arrivée de gaz. At one of its ends, said handle 1 is shaped as a handle 2 including a lever 3 for controlling the gas supply.
A 1, autre extrémité, le manche 1 formé par un tube métallique creux est aplati afin de permettre la fixation d' une lame 4 par des moyens de fixation dérnontables 5, par exemple des boulons, ce qui la rend interchangeable. At 1, another end, the handle 1 formed by a hollow metal tube is flattened in order to allow the fixing of a blade 4 by non-removable fixing means 5, for example bolts, which makes it interchangeable.
Peu avant 1' exUrémité à laquelle est fixée la lame 4, le manche 1 est coudé en 20 afin que tout en tenant celui-ci globalement parallèlement au mur à décaper, 1' on présente la lame 4 avec une inclinaison permettant de soulever aisément le revêtement. Shortly before the end to which the blade 4 is fixed, the handle 1 is bent at 20 so that while holding the latter generally parallel to the wall to be stripped, the blade 4 is presented with an inclination making it possible to easily lift the coating.
Suivant 1' invention, des moyens de chauffage sont prévus au dessus de lame. According to the invention, heating means are provided above the blade.
Un brûleur 6 est positionné au dessus de la lame 4 et orienté de manière à chauffer ce qui se trouve à l'avant de cette lame. A burner 6 is positioned above the blade 4 and oriented so as to heat what is at the front of this blade.
Ainsi, en prenant un seul dispositif en main, l'ouvrier a en sa possession à la fois le moyen de chauffage dont il peut régler la puissance au moyen du levier 3 d'arrivée de gaz, et le moyen de décoller le revêtement, formé par la lame 4. Thus, by taking a single device in hand, the worker has in his possession both the heating means of which he can adjust the power by means of the gas inlet lever 3, and the means of peeling off the coating, formed by blade 4.
Le manche 1 est de longueur telle que l'on peut le tenir fermement en positionnant une main sur la poignée 2 et l'autre main à proximité du coude 28 2 dudit dudit manche. The handle 1 is of such length that it can be held firmly by positioning one hand on the handle 2 and the other hand near the elbow 28 2 of said handle.
Le brûleur 6 étant positionné afin de chauffer le revêtement situé devant la lame 4, on est sûr de toujours agir avec ladite lame sur une portion chaude. The burner 6 being positioned in order to heat the coating located in front of the blade 4, it is certain to always act with said blade on a hot portion.
Suivant un mode préféré de mise en oeuvre de l'invention et tel que représenté, un second brûleur 7 est prévu et est orienté de manière à chauffer une surface de revêtement, située immédiatement à côté de celle sur laquelle on travaille. According to a preferred embodiment of the invention and as shown, a second burner 7 is provided and is oriented so as to heat a coating surface, located immediately next to that on which one is working.
Par cette disposition, en se déplaçant en direction de ce second brûleur 7, le revêtement subit deux périodes de chauffage et est alors plus facile à soulever. By this arrangement, by moving in the direction of this second burner 7, the coating undergoes two periods of heating and is then easier to lift.
Les brûleurs 6, 7 sont maintenus en place par une plaque de support 8 fixée par exemple par soudure sur le manche 1. The burners 6, 7 are held in place by a support plate 8 fixed for example by welding on the handle 1.
L'alimentation en gaz desdits brûleurs se fait par un tuyau d'alimentation 9 dont on peut modifier le débit par le levier 3. The gas is supplied to said burners by a supply pipe 9, the flow rate of which can be modified by lever 3.
Un tel dispositif présente également un pontet sur la partie supérieure. Ce pontet peut, tel que schématise être utilisé afin d'accrocher le dispositif à un câble passant par exemple autour d'une poulie et à l'extrémité duquel on accroche un contre-poids. Une telle disposition permet de soulager l'ouvrier d'une partie du poids du dispositif, afin de lui éviter de la fatigue et de lui permettre de mieux manipuler le dispositif. Such a device also has a trigger guard on the upper part. This bridge can, as shown diagrammatically, be used in order to hang the device on a cable passing for example around a pulley and at the end of which a counterweight is hung. Such an arrangement makes it possible to relieve the worker of part of the weight of the device, in order to avoid fatigue and allow him to better handle the device.
