Definitions

  • the invention relates to a method for applying liquid to pasty material according to the preamble of claim 1.
  • Such a method is known from AU-B-507 426. According to this method, the repair of porous or cracked areas on buildings is possible. In this case, a specific surface section is covered with a fluid-tight film, and this covered area is then evacuated. Subsequently, the material to be fed is brought into the area below the film, so that it can penetrate into the cracks and surface roughness without air remaining and the introduction of the material with special needs.
  • a device according to the preamble of claim 3 is known from AU-B-507 426.
  • the vacuum chamber surrounds the edge surface around which the material chamber adjoins the surface to be treated.
  • the known device is provided for discontinuous work in which the device remains on a treated surface section until the introduced material has hardened.
  • the known device has the disadvantage that the negative pressure present possibly sucks material introduced into the cracks in the surface from the surface.
  • the invention has for its object to improve a generic method in such a way that the material application can be carried out in a simple manner and that work steps are saved.
  • the invention is also intended to provide a device for carrying out this method.
  • the invention proposes to apply the material as a material supply within the border of a container and then to pull it out of this material supply through the gaps on or in the surface by means of an external negative pressure, so that a uniform and thorough filling of all gaps is ensured . Outgassing of the material is favored at the same time by the negative pressure, so that the risk of gas bubbles formation after application of the material is reduced.
  • the method according to the invention has the advantage that the vacuum draws the material deep and completely into the joints, cracks and other cavities on or under the boards, so that both a mechanical Strength as well as chemical resistance and tightness of the grouted surface can be guaranteed.
  • the method according to the invention brings about a rapid and uniform coating of the surface without requiring multiple work steps or having to repeat individual work steps. In this way, hitherto craftsmen or unskilled workers can carry out previously demanding work with the method according to the invention both in the grouting and in the coating, while at the same time ensuring a good work result.
  • the risk of outgassing can in particular be excluded by first exposing the material to be applied to the negative pressure while it is still in the material container.
  • a device according to the invention advantageously has a vacuum chamber, the device being placed on the surface to be treated with an opening in the vacuum chamber. The negative pressure is then present in the joints and other cavities in the floor, so that material is sucked out of the material container into these cavities.
  • a device can consist of a housing which is divided into two areas by a partition.
  • the partition runs through an opening in the housing so that a vacuum chamber can be formed on one side of the partition and a material container can be created on the other side.
  • a device according to the invention can be achieved in a simple manner if the vacuum chamber does not have its own device for generating a vacuum, but only a suction connection. In this way, a very light and handy device can be created, which is correspondingly easy to use and is suitable for the treatment of both horizontal and vertical surfaces.
  • the fill level with material can be easily checked on the one hand and material can be refilled in a simple manner while working with the device according to the invention - on essentially horizontal surfaces.
  • the material container can, however, also be closed, that is to say have a lid, an opening being advantageously then provided on the material container, in order first to be able to degas the material if necessary by applying a negative pressure.
  • this additional opening for the material outlet can also serve to pressurize the material in the material container, so that the pressure difference for sucking in the joints or coating compound is increased. This pressure difference results from the underpressure generated outside the material container and the spherical pressure or the pressure of the material weight or also from the excess pressure additionally applied to the material.
  • the provision of a lid on the material container is also advantageous if not horizontal but oblique or also vertical surfaces are to be grouted or coated.
  • the housing 1 generally designates a device which comprises a housing 2.
  • the housing 2 has a straight rear wall 3 and a curved end wall 4 and a cover 5.
  • the housing 2 does not have a bottom, but is open on its underside.
  • a partition 6 divides the housing into a vacuum chamber 7 and a material container 8.
  • the material container 8 is an open material shaft without lid and bottom.
  • the lower edge of the housing 2 is provided with a sealing lip 9.
  • a suction nozzle 10 is arranged above the vacuum chamber 7 and is connected to the vacuum chamber 7.
  • the device 1 has a handle with which it can be pulled over the surface to be treated.
  • the handle is attached to the housing 2 with two articulated arms 11.
  • the device 1 has wheels on its underside.
  • two rigidly arranged wheels 12 and a movable wheel 14 can be provided.
  • the wheels 12 and 14 also ensure that the device 1 is not supported on the sealing lip 9 on the floor when vacuum is applied. Rather, this is done by the support effect of the wheels 12 and 14. In this way, a very soft and supple sealing lip 9 can be used, which does not transmit any support forces, but can ensure a particularly good seal due to its softness.
  • the layering device 1 is placed on a tiled or clad floor and material is introduced into the material shaft, that is, into the material container 8.
  • a vacuum is now applied to the suction nozzle 10, in the simplest case by connecting a vacuum cleaner.
  • the suction power depends on the material used, its viscosity and the width of the joint from.
  • the lower edge of the partition 6 is also provided with a sealing lip, not shown for reasons of clarity, so that the negative pressure is not or almost not applied to the material in the material container 8 over the tile surface. Rather, the negative pressure is applied to the material through the joints between the tiles, so that the material is sucked into the joints. The material is also degassed by the vacuum.
  • the material container 8 can first be sealed by a plate which is arranged on its underside. Then a degassing cover is placed on top, which also has a suction connection. A negative pressure is now directly applied to the material container 8 via this second suction connection of the device 1, so that the material contained therein is degassed. After removing the two lids, the device can be used as described.
  • the device 1 When grouting, the device 1 is guided over the tiles, so that the tiles are automatically scraped off due to the sealing lip 9.
  • two usual and previously required work steps are carried out, namely the application of the jointing compound and the doctoring of the tiles, so that the joint material is flush with the tile surface.
  • the lower edge of the material container 8 can either be designed without a sealing lip or have a sealing lip that is not very conformable and only imperfectly seals.
  • the negative pressure is applied in the negative pressure chamber 7
  • the negative pressure is applied to the material in the material container 8 via the recesses in the surface of the surface to be treated.
  • the material now flows under the lower edges of the material container onto the surface and there results in a uniformly flat and possibly sealed surface.
  • two operations can be carried out on such surfaces.
  • a porous substrate e.g. B. a coarse concrete
  • a vacuum is first applied to this surface.
  • the applied material closes the pores so that the negative pressure in the pores is maintained there.
  • the substrate also absorbs material even when the device 1 is no longer placed above the floor.
  • low-viscosity parts of a floor coating are drawn into the surface and in this way bring about excellent anchoring.
  • the surface which is uneven due to vacuuming, can be finally smoothed.
  • the distance between the lower edge of the rear sealing lip and the surface to be treated results in the layer thickness of the applied material. It can be easily adjusted using interchangeable partitions or sealing lips.
  • a curved or wavy partition or a kinked partition can also be used.
  • This irregular course of the dividing wall 6 can ensure in joints which are usually straight that not very large joint sections are filled simultaneously with joint compound. In this way, the required suction power can be kept low without affecting safe and thorough work results.
  • the housing 2 can also be made angular or in another shape. With its vacuum chamber it can also connect to the material container over a smaller or a larger area, and for example the vacuum chamber can completely enclose the material container. To ensure an optimal work result, this is only dependent on the suction power applied vote.
  • Weights can be provided in the area of the material chute to prevent the device 1 from tilting. Due to the negative pressure applied in the front area, the front area of the device 1 could possibly be lowered relative to the rear area, so that a deviation from the desired coating thickness is brought about. This can be prevented by appropriate counterweights.
  • an agitator can be provided in the material shaft 8 in order to prevent sedimentation of the supplied joint or coating material.
  • a two-component material which consists of a liquid or pasty binder, for. B. in the form of plastic and mineral or other solid additives.
  • the material chute 8 cannot be designed in the form of a storage chamber, but rather only serve to supply the surface to be grouted or coated.
  • the material of the jointing compound or the layering material can be replenished via an external feed, for example via hoses, with the two components for the jointing compound or for the coating material possibly being mixed directly in front of the material shaft.
  • this design of the device 1 has the advantage that no large proportion of remaining unprocessed material in the material shaft 8 remains and hardens. In addition, it is easy to work on vertical surfaces or the material can be fed under pressure.
  • a grating or similar spacer can be provided under the device 1 in order to prevent tiles from being raised by the application of the negative pressure, which tiles were previously laid in excess adhesive or jointing compound. In this way, the tiles could be laid very quickly by simply applying them loosely to the substrate.
  • the subsequent grouting in which the vacuum also pulls grout into cavities under the tiles, would simultaneously glue and grout the tiles.
  • the tiles can be temporarily and very quickly attached using single-point gluing, the final gluing being achieved by applying the grout.
  • the tiles are then fixed not only by means of adhesive forces, but also by means of a mechanically positive anchoring, since the cavities under the tiles are completely filled.
  • the rear wall 3 can run obliquely with respect to the pulling direction of the device 1, so that the sealing lip 9 scrapes off obliquely in the region of the rear wall 3 and is not simultaneously guided over a joint over its entire length.
  • This rear section of the sealing lip 9 can advantageously be a have a wedge-shaped cross-section for better squeegees, while the sealing lip can also be made wide for good tightness in the other areas.
  • This rear squeegee edge can also be designed to be liftable and adjustable so that the layer thickness on the floor can be adjusted in this way.
  • an operation can be carried out with the device 1 without feeding the material into the material container 8.
  • vacuum treatment can be carried out on tiles that have previously been provided with adhesive or grout.
  • the adhesive is pulled up through the substrate and excess adhesive is accumulated in the material container 8. In the case of less supplied areas, this excess adhesive is released again, so that the joint pattern can be evened out.
  • the sealing lip 9 can either be highly elastic or be pressed down by springs. Since the housing 2 is supported on the ground via the wheels 12 and 14, a good seal can be ensured in this way.
  • the device 1 can comprise a pressure regulator which, for example, enables the suction power to be regulated with the aid of external air openings, it being possible for control to be provided by a pressure gauge. In this way, a simple suction device with constant suction power can be used, the adaptation to different operating conditions taking place in the device 1.
