Definitions
- the invention relates to a device for coating surfaces on buildings by means of hardenable thick matter, consisting of a connecting piece for a thick matter feed, from a nozzle arrangement for applying a
- Thick from a coating leg for leveling the surface of the applied layer
- the invention also relates to ner drives for the production of certain objects and elements for buildings and the like using the device according to the invention
- a flat plaster application nozzle is arranged at the front end of a cement delivery hose, with which a Mortel stream can be applied in layers on a surface.
- the outlet opening of the nozzle is perpendicular to the
- This flat nozzle designed in this way is not suitable for plastering walls.
- the nozzle which is freely guided by hand in the space in front of the wall, is at different distances from the one to be coated due to the Mortel stream escaping at different application speeds and under different pressure
- EP patent application 215 243 proposes a device for applying a layer capable of setting. To avoid the rebound of the thick material-air mixture sprayed onto the wall, the nozzle is directed at an angle of 30 - 45 ° to the wall and builds up the layer one after the other in inclined positions.
- this tape ensures that the surface of the applied layer is balanced and solidified in a certain sense.
- the endless belt is fed to the spray nozzle at a defined distance.
- Such a device can certainly be used with advantages if layers are large
- Thickness should be applied to very irregular surfaces. Such a device cannot be used for coating, as a rule, flat building surfaces with relatively thin layers.
- the thick material cannot be applied in such a targeted manner that the thick material layers on the wall follow
- the scattering mortar jet also hits the uncoated hard wall.
- a mortar spray nozzle which can be pressurized with compressed air, is arranged on this work sled and executes a reciprocating movement with a simultaneous, slow lifting movement of the work sled. In this way, zigzag-shaped mortar is applied to the building surface.
- a spreading leg is arranged below the working level of the spray nozzle, which equalizes the applied mortar layer when the working slide moves upwards.
- this device is certainly suitable for applying a layer of mortar on large, flat surfaces which have only a limited number of interruptions.
- Particles are usually waste.
- the recessed mortar elements also contaminate the guide for the work sled and the work sled itself. Permanent cleaning of this guide is therefore essential.
- the work sledge cannot be designed so that it can be guided by hand on the coated wall.
- the recoil of the to-and-fro nozzle and the masses to be moved when guiding the nozzle make it impossible to guide such a work carriage by hand.
- the document US 18 29 479 shows a device for applying thick material to a building surface, where the outlet opening of the nozzle is framed by a plate which forms a plane. The layer of mortar is spread out in the plane of the slab. A string leg is not specially arranged.
- the document DE-PS 969 391 shows a plastering device which hurls the plastering tray onto the surface to be coated by means of a pair of spray rollers which is located in a housing.
- the aim of the invention is to avoid the disadvantages of this device.
- the object of the invention is to provide a manually operable application device, which ensures that the mortar or other thick materials can be applied in relatively thin layers without rebound, while avoiding air pockets on preferably flat building surfaces.
- the device should be able to be connected to a continuously pumping mortar pump, which can be guided along the wall to be plastered with a reservoir.
- this object is achieved in principle by the elements shown in claim 1. Due to the defined spreading of the thick material layer and the tangential flowing application of the same on the building surface, while at the same time equalizing the layer thickness by the coating leg, the mortar bounces off the wall with certainty. Practice has also shown that this procedure reliably prevents air pockets between the surface of the building and the thick material applied.
- the adhesion of the layer to the building surface is no different from a sprayed-on layer.
- the flat nozzle on the wall is simply too handle and guide. It is only necessary to manipulate the dead weight of the flat nozzle and the hose plus the thick matter contained therein.
- the device is guided via the extremely narrow side walls directly on the building surface. No additional guide structures are mandatory.
- the embodiment according to claim 2 makes it possible to apply thick layers of material in a precisely defined width and to apply several layers of thick material on the wall directly next to one another, almost without gasses.
- the thick matter feed according to claim 6 ensures an almost continuous thick matter transport to the application device.
- Vane pump including storage for the thick material can be carried easily on the surface of the wall, ceiling or floor to be coated.
- the hose between the vane pump and application device can be cleaned with minimal loss and has a minimal impact on the person who drives the nozzle.
- Irregular surfaces e.g. B. stucco profiles
- the design of the coating leg according to claim 9 It is advisable to provide a separate nozzle for each type of profile, the interior of which has only the absolutely necessary dimensions for the thick material feed. The effort for reworking the profiles can be reduced to a minimum.
- Claim 11 defines a method which is particularly suitable for the protection of building exterior walls covered with polyurethane foam. Due to the fluid application of the curable thick layer, the gluing of the fabric can be avoided in a special operation. The thick material is pressed through the small openings in the tissue on the back of the same. There it creates a stable connection between the fabric and the wall. The device can also be used with particular advantages in the manufacture of so-called Rabitz walls. The fact that the thick material flow is applied to the fabric or grid in a fluid manner prevents rebounding or flinging through of thick material particles. Means for shielding thick material splashes are no longer required.
- the working method according to claim 13 enables the production of relatively thin-walled, relief-like wall sections which can be placed and fastened on other structural parts of the building after the curing process.

- the flat nozzle 2 is connected to the hose 53 via its connecting piece 29.
- the flat nozzle 2 has a distribution system 41, 42 with individual flat nozzles 21, 22, 23, 24.
- the outlet openings of the individual flat nozzles 21, 22, 23, 24 open into the outlet opening 20 of the flat nozzle 2.
- the outlet opening 20 of the flat nozzle 2 is to the building surface 1 and opposite to the application direction A, here downwards, open in the plane of the applied layer 61.
- the coating leg 3 Adjacent to the outlet opening 20 in the plane of the surface of the applied layer 61 is the coating leg 3, which is adjustably fastened to the underside of the flat nozzle wall 2 by means of fastening angles 31 and set screws 32.
- a cover strip made of elastic material is exchangeably arranged with the aid of a fastening strip 262.
- This cover strip 261 is inclined slightly downward and shields the outlet opening 20 upwards. Due to the elastic design of the cover strip, an almost uniform layer thickness 61 can be ensured even on an irregular surface.
- a closure member 27 or 28 is provided in the entrance area of each individual flat nozzle.
- This locking member 27, 28 is pivotable about a pin 271, 281 and can be adjusted via the locking lever 272 or 282 in four different positions.
- both individual flat nozzles 21 and 22 or 23 and 24 are open and fully functional. Based on the closure member 27 two further positions are shown. In the position 27 'shown in dashed lines, the individual flat nozzle 21 is closed. The thick material flow only reaches the outlet opening via the individual flat nozzle 22. In position 27 "(dash-dot line) both individual flat nozzles of this line are closed. The flow of mortar only reaches the outlet opening 20 via the individual flat nozzles 23 and 24.
- the individual flat nozzle 22 is closed. This position is selected if you want to apply little or no mortar in a narrow area of the surface.
- the flat nozzle 2 is preferably formed by the rear wall of the flat nozzle 2 and the distributor sections 41 and 42 of FIG
- a button 522 is provided in the left section, which the
- Vane pump 52 allows.
- FIG. 2 shows an enlarged representation of the thick material flow through the flat nozzle 2.
- the thick material 6 consequently passes through the outlet opening 20 in a narrow, homogeneous stream directly onto the surface 1 to be coated. Any trapped air escapes upward around the front edge of the cover strip 261. This process is supported by the action of the coating leg 3.
- the applied layer 61 is pressed against the surface 1 and the surface thereof is smoothed.
- the width of the layer 61 is limited by the side walls 25.
- the side walls 25 consist of narrow metal sheets and are supported on the surface 1 in a sliding manner. It is expedient to round the side walls 25 at least in the discharge direction A upwards and to the surface 1 or to provide them with a chamfer.
- the dimensions of the side wall 25 should be such that it is greater than the maximum layer thickness. You should the outlet opening 20 and the coating zone in the area of the side wall 25
- FIG. 3 The overall arrangement of the application device is shown in FIG. 3.
- the movement of the application device 2 from the floor to the ceiling is shown schematically there by the representation of the respective end positions.
- Floors and ceilings can of course also be coated in the same or a similar manner with this application device 2.
- the accumulator 51 and the pump which is preferably designed as a vane pump 52, are arranged on a flat carriage 54, which also carries the actuating and control means for the motor 520 of the vane pump 52.
- the pump conveys the thick matter 6 continuously into the flat nozzle 2 via the hose 53.
- the operator can actuate the setting button 522 arranged in the grip area of the flat nozzle 2.
- the respective setting information is transmitted via line 523 to the actuator 521 of the vane pump 52. In this way you can start or interrupt the flow of mortar, or change its flow rate.
- the flat nozzle 2 is shown again in side view.
- the intention is to show the technical means by which the cross section of the flat nozzle 2 can be designed so that the supplied mortar / thick material 6 can be distributed in the flat nozzle 2 at a constant speed and the thick material flow as a uniform layer 61 on the building surfaces 1 can apply.
- FIGS. 5 and 6 show two views of a modified device 7, in which a profiled coating leg 71 is provided. With this device 1 stucco profiles 62 can be applied to flat surfaces. The coating leg 71 is continuously profiled. For the compensation of
- Pressure differences which are due to the volume-related differences between the conveying speed and the application speed, are provided at least one pressure relief opening 76. In this way, the occurrence of irregularities in the profile layer 62 is avoided.
- profile flat nozzles or attachments therefor can be used, whose outlet opening at the end of the coating leg 71 is inclined to the application direction A.
- FIG. 7 shows the application of a mortar layer 65 to a surface 1 which is covered with polyurethane foam panels (PUR foam panels).
- PUR foam panels polyurethane foam panels
- a reinforcement or reinforcement made of fabric 80 is to be introduced in this working method.
- the fabric was first glued to the PUR layer and then, after the adhesive had set, the appropriate plaster was applied.
- the process can be simplified with the present device.
- the fabric 80 is attached to the upper boundary of this surface 1 with a strip 84 and stretched in front of the surface 1.
- the mortar is applied using the device 2 described. Due to the flowing application process, which takes place at low speed but with adequate pressure, the thick material 6 also penetrates through the existing holes onto the back of the fabric 80 and thus also ensures the connection between the fabric 80 and the surface 1.
- a so-called Rabitz wall can also be produced very advantageously with the application device 2, 51, 52, 53 (FIG. 8).
- a fabric or gauze 81 stretched in a space 82, 83 is covered on both sides with at least one layer 63, 64 each.
- 641 thick material penetrates through the openings in the fabric or in the gauze 81.
- the second layer 63 is then applied to this thick material 641.
- the two layers 64 and 63 are thus stably connected to one another, including the gauze 81.
- the manufacturing process is controlled with minimal waste. Thick matter particles are neither thrown through nor thrown back. It is avoided that parts of the thick material layer 64, 65 fall off due to vibrations of the fabric or the gauze 81 and have to be applied again.
- the proposed device is also ideal for that
- Thermally insulating layers 65 require air or gas enclosing hollow bodies - preferably polyurethane foam balls 66 (PUR foam balls). Balls of this type could not be used with the previously customary method in which the thick materials were sprayed on by pressure.
- Binder penetrates into the cavities and hardens there. The isolating effect did not occur or only to a very limited extent.
- mixtures of PUR foam balls, cement as a binder and water as a reaction element can be surprisingly produced and applied to building surfaces.
