Description

L'invention concerne une installation pour le ravalement de bâtiments.The invention relates to an installation for cleaning buildings.

L'installation est caractérisée en ce qu'elle comprend une cabine présentant une face avant ouverte destinée à être disposée contre la face avant du bâtiment à ravaler, une cloison intermédiaire parallèle à la face avant ouverte et pourvue de ventilateurs aspirant l'air de la zone de la face avant, un plancher pour le support des ouvriers prévu entre la face avant et la cloison intermédiaire, une face latérale arrière pourvue d'ouvertures d'évacuation d'air, un panneau filtrant disposé parallèlement à et entre la cloison intermédiaire et la cloison arrière, une face inférieure en forme générale de trémie pourvue d'un conduit d'évacuation des particules solides recueillies par le panneau filtrant, un entourage de la face avant ouverte et faisant saillie à l'extérieur de la cabine par rapport à cette face avant, cet entourage étant réalisé en un matériau souple disposé sur une ossature constituée de boudins gonflables.The installation is characterized in that it comprises a cabin having an open front face intended to be disposed against the front face of the building to be swallowed, an intermediate partition parallel to the open front face and provided with fans sucking air from the area of the front face, a floor for the support of workers provided between the front face and the intermediate partition, a rear side face provided with air exhaust openings, a filtering panel arranged parallel to and between the intermediate partition and the rear partition, a lower face in the general shape of a hopper provided with a conduit for discharging the solid particles collected by the filtering panel, a surround of the open front face and projecting outside the cabin relative to this front face, this surround being made of a flexible material placed on a frame made up of inflatable tubes.

Suivant une autre caractéristique de l'invention, les ouvertures de la face latérale arrière sont pourvues de panneaux inclinés vers le haut et vers l'extérieur de la cabine.According to another characteristic of the invention, the openings in the rear side face are provided with panels inclined upwards and outwards from the cabin.

Suivant une autre caractéristique de .l'invention, la cabine est supportée par l'extrémité du bras de levage d'un engin de levage, la liaison de la cabine au bras étant réalisée par un montage à rotation de la cabine suivant un axe vertical X-X parallèle à la face avant et par un montage à pivotement suivant un axe horizontal perpendiculaire à l'axe X-X et à l'axe du bras de levage.According to another characteristic of the invention, the cabin is supported by the end of the lifting arm of a lifting machine, the connection of the cabin to the arm being produced by a rotational mounting of the cabin along a vertical axis XX parallel to the front face and by a pivoting assembly along a horizontal axis perpendicular to the axis XX and to the axis of the lifting arm.

L'invention est représentée à titre d'exemple non limitatif sur les dessins ci-joints dans lesquels :

  • - la figure 1 est une vue en coupe verticale schématique de l'installation,
  • - la figure 2 est une vue de droite de la figure 1.
The invention is shown by way of nonlimiting example in the accompanying drawings in which:
  • FIG. 1 is a schematic vertical section view of the installation,
  • - Figure 2 is a right view of Figure 1.

L'installation représentée sur les dessins comprend essentiellement une cabine 1, par exemple en tôle d'aluminium, qui est pourvue d'une face latérale avant 2 ouverte. Cette face avant est destinée à se placer en regard de la paroi du bâtiment à ravaler afin que les ouvriers disposés sur le plancher 3 puissent projeter sur le bâtiment à l'aide d'une buse, des particules solides véhiculées par de l'air sous pression.The installation shown in the drawings essentially comprises a cabin 1, for example made of aluminum sheet, which is provided with an open front side face 2. This front face is intended to be placed opposite the wall of the building to be cut down so that the workers placed on the floor 3 can project onto the building using a nozzle, solid particles conveyed by air under pressure.

Ces particules sont constituées par de la poudre de silice sèche dont les dimensions sont comprises entre 1 et 70 microns, de façon à pouvoir effectuer rapidement un nettoyage efficace du bâtiment, sans détérioration de sa façade.These particles consist of dry silica powder whose dimensions are between 1 and 70 microns, so that effective cleaning of the building can be carried out quickly, without damaging its facade.

A l'intérieur de la cabine 1 est prévue une cloison verticale intermédiaire 4 parallèle à la face avant 2 et séparée de cette face avant par le plancher 3. Cette cloison intermédiaire 4 est pourvue d'une batterie de ventilateurs 5 qui ont pour but d'aspirer l'air situé dans la zone avant Z1 et qui contient en suspension des particules de poudre de silice afin de projeter cet air sur un panneau filtrant 6 disposé parallèlement et derrière la cloison 4.Inside the cabin 1 is provided an intermediate vertical partition 4 parallel to the front face 2 and separated from this front face by the floor 3. This intermediate partition 4 is provided with a battery of fans 5 which are intended to '' suck in the air located in the front zone Z1 and which contains suspended particles of silica powder in order to project this air onto a filter panel 6 arranged parallel and behind the partition 4.

La face latérale arrière 7 de la cabine est pourvue d'ouvertures 71. Sur le bord inférieur de ces ouvertures sont fixés des panneaux 8 qui sont inclinés vers l'extérieur et vers le haut de la cabine afin de constituer des déflecteurs évitant que l'air aspiré par les ventilateurs 5 et qui a traversé le panneau filtrant 6 soit projeté horizontalement à l'extérieur de la cabine.The rear lateral face 7 of the cabin is provided with openings 7 1 . On the lower edge of these openings are fixed panels 8 which are inclined towards the outside and towards the top of the cabin in order to constitute deflectors preventing the air sucked in by the fans 5 and which has passed through the filter panel 6 from being projected horizontally outside the cabin.

Devant chaque ventilateur 5 débouche une tubulure 91 de projection d'eau, tandis que sur le bord supérieur de la face avant du panneau filtrant 6 il est également prévu une rampe 92 de projection d'eau.Before each fan 5 opens a tube 9 1 for spraying water, while on the upper edge of the front face of the filter panel 6 there is also a ramp 9 2 for spraying water.

Les tubulures 91 en projetant de l'eau sur les pales des ventilateurs, ont pour effet d'humidifier l'air et les particules solides aspirées afin que ces particules se déposent contre la face avant du panneau filtrant 6. Ensuite, l'eau qui s'écoule de la rampe 92 contre le panneau 6 lave en permanence la face avant de ce panneau afin que le mélange d'eau et de particules soit récupéré dans une trémie 10 formant la face inférieure de la cabine, puis évacué par un conduit 11.The pipes 9 1 by projecting water onto the blades of the fans, have the effect of humidifying the air and the solid particles aspirated so that these particles are deposited against the front face of the filter panel 6. Next, the water flowing from the ramp 9 2 against the panel 6 constantly washes the front face of this panel so that the mixture of water and particles is recovered in a hopper 10 forming the underside of the cabin, then discharged by a conduit 11.

La tubulure 91 et la rampe 92 sont alimentées en eau sous pression par une canalisation souple 12.The tubing 9 1 and the ramp 9 2 are supplied with pressurized water by a flexible pipe 12.

La face avant ouverte 2 de la cabine est pourvue d'un entourage 13 réalisé à l'aide d'un matériau souple 131 tel qu'une bâche, monté sur une ossature 132 réalisée à l'aide de boudins gonflables par de l'air.The open front face 2 of the cabin is provided with an surround 13 made using a flexible material 13 1 such as a tarpaulin, mounted on a frame 13 2 made using inflatable tubes by l 'air.

Cet entourage comprend ainsi un boudin périphérique avant 133 et des boudins 134 qui relient le boudin 133 à la périphérie de la face avant 2.This surround thus comprises a front peripheral flange 13 3 and flanges 13 4 which connect the flange 13 3 to the periphery of the front face 2.

La cabine 1 est supportée à l'extrémité du bras de levage 14 d'un engin de levage. La liaison entre la cabine et le bras comprend deux tubes concentriques 15 et 16 dont l'un,15,est fixé à la base de la trémie 10 et dont l'autre,16,est fixé sur une chape 17 pivotante,par l'intermédiaire d'un axe 18, sur le bras 14. Le tube extérieur 15 comporte à sa base une roue dentée 151 avec laquelle engrène une vis sans fin 152 entraînée par un moteur hydraulique 153. Les tubes concentriques 15 - et 16 constituent donc un montage à rotation de la cabine suivant un axe vertical X-X parallèle à la face avant 2 de la cabine. L'axe de pivotement 18 est perpendiculaire à l'axe X-X et à l'axe 141 du bras de levage 14.The cabin 1 is supported at the end of the lifting arm 14 of a lifting machine. The connection between the cabin and the arm comprises two concentric tubes 15 and 16, one of which, 15, is fixed to the base of the hopper 10 and of which the other, 16, is fixed to a pivoting yoke 17, by the intermediate an axis 18, on the arm 14. The outer tube 15 has at its base a toothed wheel 15 1 with which engages an endless screw 15 2 driven by a hydraulic motor 15 3 . The concentric tubes 15 - and 16 therefore constitute a rotational mounting of the cabin along a vertical axis XX parallel to the front face 2 of the cabin. The pivot axis 18 is perpendicular to the axis XX and to the axis 14 1 of the lifting arm 14.

Le pivotement de la chape 17 est assuré par un vérin hydraulique 19 de façon à pouvoir modifier l'inclinaison de la cabine et, également, de façon à pouvoir placer cette cabine horizontalement dans le prolongement du bras 14 lors du déplacement de l'engin de levage. La rotation des tubes 15 et 16 l'un par rapport à l'autre à l'aide du moteur 153 permet de modifier l'orientation de la cabine pour disposer la face 2 en regard du bâtiment à ravaler sans être obligé de modifier la position de l'engin de levage.The pivoting of the yoke 17 is ensured by a hydraulic cylinder 19 so as to be able to modify the inclination of the cabin and, also, so as to be able to place this cabin horizontally in the extension of the arm 14 when the machine moves. lifting. The rotation of the tubes 15 and 16 relative to each other using the motor 15 3 makes it possible to modify the orientation of the cabin so as to have the face 2 facing the building to be swallowed without being obliged to modify the position of the lifting device.
