Definitions

  • the invention relates to a device for collecting and draining liquids that are contaminated with pollutants when machining building surfaces, building facades and the like, in particular during renovation work.
  • the previously known collecting channels are completely unsuitable for collecting and collecting the liquid cleaning agents spraying from building surfaces, because cleaning agents applied by high pressure spray to a considerable extent back into the scaffolding and drip uncontrollably from there onto the ground.
  • the usual protective tarpaulin used on the outside of a scaffolding can only ensure that the splashing back liquid quantities do not reach the outside, but are mainly limited to the floor plan of the erected scaffolding.
  • the seamless collection is particularly difficult because scaffolding follows the facade and inevitably have corners that interrupt the collection facilities. A facility that meets the official requirements for environmental protection and that gathers the fluids used to process the building surfaces is not known.
  • the invention is based on the object of providing a collecting device of the type mentioned in the introduction, with which it is possible to collect all of the liquid used for cleaning, stripping, preserving and the like at the lower end of the surface to be processed, even then, if it is blasted against the surface to be worked with the help of high-pressure devices.
  • the facility should be able to follow the course of the scaffolding without interruption, even if it is arranged on building corners and follows sharp changes in direction of the building fronts.
  • the invention for solving this problem is characterized by commercially available gutter sections which can be joined together by separate connecting parts which are provided in the area of the posts of a scaffolding with indentations for encompassing the posts, the gutter sections resting in holders which can be fastened to the posts and the distances between the two Channels arranged on the long sides of the scaffold can be bridged with foils on the one hand and between the building surface to be machined and the adjacent gutter on the other.
  • the entire area between the surface of the building to be processed and the side of the scaffolding facing away from the building can be covered by the foils just above the soil, the liquid collecting thereon being directed into the channels and being discharged from there into storage containers. Even the amount of liquid splashing back from the surface to be worked can be collected with certainty, since the tarpaulin usually used on the outside of the scaffolding ends in the area above the outer channels, and the liquid that runs down the tarpaulin can thereby be caught and removed.
  • the posts are sealed.
  • the non-liquid-tight gaps between the connecting parts and the post can be sealed by means of elastic sealing compound or by a cover cap attached to the connecting part.
  • the flexible connecting parts are able to follow right-angled changes in direction of the scaffolding. Attachment is possible on all known scaffolding systems.
  • baffle plate that can be attached above the gutters ensures that the solids are caught, for example cleaning parts and brick fragments. Liquid can drip down through sieve-like openings in the baffle plate.
  • the device according to the invention it is possible to compensate for all occurring variable distances between the scaffolding and the building. It consists of a few prefabricated, handy parts that can be easily assembled. There is no need to drill holes for screwing connection strips onto structures, which is not permissible, particularly in historical structures.
  • the brackets, which can be attached to the post by friction, can be arranged at any point and at any height.
  • the connecting part 1 according to FIG. 1 is provided with an indentation 2 for enclosing a scaffold post 32.
  • the connecting part 3 according to FIG. 2 shows two indentations arranged next to one another for two scaffold posts arranged next to one another, for example at scaffold connection points.
  • a short version 6 with an indentation is shown in FIG. 3.
  • connecting parts 7, 8 and 35 can be used without indentations.
  • shoulder-like grooves 9 for receiving sealing strips 10 for the production of liquid-tight connections with the adjoining, not shown, commercially available gutter sections 34 (FIGS. 15, 16).
  • the gutter brackets 11, 12 and 13 consist of semicircular clamping ring parts 14 and 15, which are connected in a hinge-like manner with the aid of pivot pins 16 and can be pressed firmly against one another by means of screws 17 after embracing a scaffold post.
  • Holding arms 18 are welded to one of the clamping ring parts, which in turn carry welded flat holding profiles 19, on which the bow-shaped holders 20 for receiving the channel sections are fastened, for example welded.
  • the example according to FIG. 6 differs from that according to FIG. 7 only by the arrangement of the holding bracket on the opposite side of the clamping ring.
  • the exemplary embodiment according to FIG. 8 shows two bow-shaped holders on both sides of the clamping ring 14, 15.
  • the connecting part 21 shows a rigid connecting connection 22 and a flexible Ver binding connection 23. This consists of several spaced-apart ribs 24, between which flexible wall parts 25 extend.
  • the connecting part 26 according to FIG. 10 shows a double indentation with flexible connecting parts arranged on both sides.
  • Flexible connecting parts without indentations can be designed according to FIG. 11.
  • a baffle 27 (FIG. 12) can be added to the device consisting of channels, connecting parts and foils, which can be fastened to the scaffolding above the foils.
  • the baffle plate is provided on its narrow sides with sheet strips 28 which are bent downwards and with which it can be hung in U-shaped holding profiles 29.
  • the U-profiles 29 are carried by holding brackets 30, which in turn are each firmly connected to a two-part, screwable clamping ring 31.
  • the baffle plate 27 can be designed in the form of a sieve in order to drain dirty water and the like adhering to the solid particles.
  • FIG. 15 shows a scaffolding with vertical posts 32, which is set up on a building wall to be cleaned with a corner projection 33.
  • the scaffolding follows this lead. Accordingly, the entire collecting device with all its individual parts must follow this course.
  • the commercial gutter sections 34 are fastened to the vertical scaffold posts with the connecting parts shown in FIGS. 1 to 11.
  • a film 40 with an upward inclination extends from the gutter sections fastened to the inside of the scaffold to the building wall and is fastened there by means of a self-adhesive strip 41.
  • the area between the channels, that is to say within the scaffolding, is covered with a further film 42. It is also attached to the gutter edges with adhesive strips.
  • the entire gutter attached to the outer posts of the scaffold is arranged above the inner gutter.
  • the collected liquid can be passed into an intermediate container 50, from where it can be conducted into a mobile tank 52 via a submersible pump 51. If available, the liquid to be disposed of can be fed into a neutralization and cleaning tank 53 at the place of use, from where the liquid can be used again in the recycling process via a compressor 54.
  • Scaffolding tarpaulins 60 are usually hung on the outside of the scaffolding and are intended to prevent the liquid processed under high pressure from spraying too far. These tarpaulins can extend into the grooves 34, so that liquid running off on the inside is collected and drained with certainty. For this purpose, the outside of the channel is attached to the scaffold pointing outwards.
