Definitions

  • the invention relates to a cabin for cleaning facades of buildings according to the preamble of claim 1.
  • Cabins are already known (see FIG. 1) which are fixed to the end of the lifting arm of a crane and which are applied by their open front face 1 against the facade to be cut back.
  • On the floor 2 of this cabin are the workers who, using sand spray nozzles, clean the area of the facade delimited by the opening 1.
  • the rear face 3 of this cabin is provided with fans 4 associated with filtering elements, which have the purpose of sucking in the air in which there is suspended sand, in order to filter it then evacuate it.
  • the object of the present invention is in particular to remedy these drawbacks and for this purpose relates to a cabin for the cleaning of building facades, comprising an open front face intended to be placed against the facade to be cut, cabin characterized in that the periphery of the open front face comprises means producing an air curtain directed towards the facade to be swallowed.
  • the walls of the cabin delimiting the opening of the front face are produced, at least in part, using inflatable tubes.
  • the inflatable tubes delimiting the walls of the cabin are provided, on the interior side of the cabin, with a flexible partition delimiting with the inflatable tubes an air passage slot forming the curtain 'air.
  • the present invention therefore aims to achieve a facelift cabin, which prevents air that having sand in suspension, is evacuated through the periphery of the opening of the cabin.
  • This cabin 6 comprises a floor 7 on which the workers are located, a rear face 8 provided with at least one suction and filter assembly 9, a front face 10 which is placed against or at least close to the facade 11 of the building to be restored, of walls 12 which delimit the two side walls, the upper wall as well as the lower wall arranged under the floor 7.
  • These walls 12 are made in the form of an inflatable element 13 comprising either separate compartments and inflatable independently of each other, or a single compartment and, in this case, cables 14 are provided inside the element in order to hold the two faces 13 1 , 13 2 of the element 13 parallel to each other.
  • a flexible wall 15 which defines with the front edge of the element 13, a slot 16.
  • the position of this flexible wall 15 is maintained relative to the inflatable element 13 using cables 14 1 preferably extending the cables 14.
  • a fan 17 is provided which produces a breath of air brought between the wall 15 and the element 13 in order to produce , through the slot 16, an air curtain 18 directed against the facade 11 of the building.
  • the effect of this air curtain is to prevent the direct exit of air from the periphery of the cabin and, on the contrary, to encourage this sand-laden air to move towards the suction assembly 9.
  • This air curtain is directed perpendicular to the facade 1 but, preferably, it will be inclined slightly inward to more effectively oppose the breath of air laden with sand produced by the projection nozzles after the air and the sand came to hit the facade being restored
  • the walls 12 form the entire depth of the cabin. It will however be understood that if this is deemed sufficient, the inflatable element 12 and the flexible wall 15 can be provided only over part of the depth of the cabin, the main thing being that the shape of the periphery of the cabin can adapt to the roughness of the facade of a building and stand against this building or at least at a distance small enough that the air curtain can prevent the exit of air loaded with sand particles.

Description

  • L'invention concerne une cabine le ravalement des façades de bâtiments selon le préambule de la revendication 1.
  • On connaît déjà des cabines (voir figure 1) qui sont fixées à l'extrémité du bras de levage d'une grue et qui s'appliquent par leur face avant ouverte 1 contre la façade à ravaler. Sur le plancher 2 de cette cabine, se trouvent les ouvriers qui, à l'aide de buses de projection de sable, nettoient la zone de la façade délimitée par l'ouverture 1.
  • La face arrière 3 de cette cabine est pourvue de ventilateurs 4 associés à des éléments de filtrage, qui ont pour but d'aspirer l'air dans lequel se trouve du sable en suspension, afin de le filtrer puis de l'évacuer.
  • Il est déjà connu de disposer un boudin gonflable 5 à la périphérie de l'ouverture 1 de la cabine, afin que ce boudin s'applique contre la façade du bâtiment en assurant une meilleure étanchéité et sans risquer de détériorer les décorations en saillie qui peuvent être présentes sur cette façade.
  • Cependant, malgré ce boudin gonflable périphérique, il apparaît que l'étanchéité n'est pas établie de manière suffisante, si bien que de l'air chargé des particules de sable, est projeté à l'extérieur, ce qui constitue une nuisance pour l'environnement.
  • La présente invention a notamment pour but de remédier à ces inconvénients et concerne à cet effet une cabine pour le ravalement des façades de bâtiments, comportant une face avant ouverte destinée à se placer contre la façade à ravaler, cabine caractérisée en ce que la périphérie de la face avant ouverte comporte des moyens produisant un rideau d'air dirigé vers la façade à ravaler.
  • Suivant une autre caractéristique de l'invention, les parois de la cabine délimitant l'ouverture de la face avant, sont réalisées, au moins en partie, à l'aide de boudins gonflables.
  • Suivant une autre caractéristique de l'invention, les boudins gonflables délimitant les parois de la cabine, sont pourvus, du côté intérieur de la cabine, d'une cloison souple délimitant avec les boudins gonflables une fente de passage de l'airformant le rideau d'air.
  • L'invention est représentée à titre d'exemple non limitatif sur les dessins ci-joints dans lesquels :
    • - la figure 1 est une vue en perspective schématique d'une cabine de ravalement de type connu,
    • - la figure 2 est une vue en coupe transversale partielle d'une cabine conforme à l'invention.
  • La présente invention a en conséquence pour but la réalisation d'une cabine de ravalement de façades, qui permet d'éviterque de l'air comportant du sable en suspension, s'évacue par la périphérie de l'ouverture de la cabine. Cette cabine 6 comporte un plancher 7 sur lequel se trouvent les ouvriers, une face arrière 8 pourvue d'au moins un ensemble d'aspiration et de filtrage 9, d'une face avant 10 qui se place contre ou tout au moins à proximité de la façade 11 du bâtiment à ravaler, de parois 12 qui délimitent les deux parois de côté, la paroi supérieure ainsi que la paroi inférieure disposée sous le plancher 7.
  • Ces parois 12 sont réalisées sous la forme d'un élément gonflable 13 comportant, soit des compartiments séparés et gonflables indépendamment les uns des autres, soit un seul compartiment et, dans ce cas, des câbles 14 sont prévus à l'intérieur de l'élément afin de maintenir parallèlement l'une à l'autre les deux faces 131, 132 de l'élément 13.
  • A l'intérieur de l'élément gonflable 13, est disposée une paroi souple 15 qui délimite avec le bord avant de l'élément 13, une fente 16. La position de cette paroi souple 15 est maintenue par rapport à l'élément gonflable 13 à l'aide de câbles 141 prolongeant, de préférence, les câbles 14. Dans la zone arrière de la cabine, est prévu un ventilateur 17 qui produit un souffle d'air amené entre la paroi 15 et l'élément 13 afin de produire, par la fente 16, un rideau d'air 18 dirigé contre la façade 11 du bâtiment. Ce rideau d'air a pour effet d'empêcher la sortie directe de l'air par la périphérie de la cabine et, au contraire, d'inciter cet air chargé de sable à se diriger vers l'ensemble d'aspiration 9.
  • Ce rideau d'air est dirigé perpendiculairement à la façade 1 mais, de préférence, il sera légèrement incliné vers l'intérieur pour s'opposer plus efficacement au souffle d'air chargé de sable produit par les buses de projection après l'air et le sable soient venus frapper la façade en cours de ravalement
  • Dans l'exemple représenté, les parois 12 forment la totalité de la profondeur de la cabine. On comprendra cependant que si cela est jugé suffisant, l'élément gonflable 12 ainsi que la paroi souple 15, pourront être prévus que sur une partie de la profondeur de la cabine, l'essentiel étant que la forme de la périphérie de la cabine puisse s'adapter aux aspérités de façade d'un bâtiment et se placer contre ce bâtiment ou tout au moins à une distance suffisamment faible pour que le rideau d'air puisse empêcher la sortie d'air chargé de particules de sable.
