Definitions

  • the invention relates to a finished wall according to the preamble of the main claim and a method for producing a finished wall according to the preamble of the independent claim.
  • the document discloses DE 195 27 275 A1 a method for producing prefabricated and plastered masonry walls, which are produced by means of an edge formwork on a horizontal formwork surface. In the process, plaster is poured into the formwork, on which insulation elements are aligned, which are poured with mortar. The document also discloses a plaster layer above the stone layer, which can be applied after a drying time of the mortar.
  • the use of masonry leads the prefabricated walls from the cited document to a disadvantageous consuming manufacture.
  • Prefabricated walls in which a load-bearing wall body is formed by pouring concrete for example, from the document DE 25 48 959 B1 known.
  • the previously known prefabricated walls of this type have the disadvantage that curing of the load-bearing concrete layer must take place before the application of a plaster layer. Accordingly, after installation on the construction site, these walls typically still have to be smoothly plastered on the inside, so they are not yet ready for wallpapering.
  • the object of the present invention is to propose a prefabricated wall which is ready for use inside and outside after the manufacturing process and which can be produced between individual production steps without dry or interim storage time.
  • the invention is accordingly also the object of proposing a simple production method for a precast wall, which requires as little rework on a construction site.
  • the claimed prefabricated wall has a load-bearing wall body, which consists at least partially of concrete and preferably of concrete reinforced with a steel grid.
  • the finished wall has on the inside of the wall body on a plaster layer, which is formed from mineral mortar and on which a fleece is attached.
  • the mineral plaster layer offers decisive advantages when making the wall. First, the plaster layer on fresh, On the other hand, the mineral plaster layer is weatherproof, so that the wall can be stored outdoors after completion and thus no additional, covered storage areas are needed. By arranged on the plaster layer fleece finally a smooth and ready-to-use surface is realized on the inside of the finished wall, which requires no reworking on the site, such as additional plastering and smoothing.
  • the nonwoven used is a glass fiber fleece. This brings the advantage of good weather resistance, which allows the wall to be stored outdoors.
  • the nonwoven spans the inside of the finished wall over its entire surface, wherein the nonwoven integrally spans a height of a floor at least in one strip. This avoids web impacts on the insides of the prefabricated walls.
  • a good and stable connection between the nonwoven and the plaster layer can be achieved by partially embedding the nonwoven in the plaster layer. Unlike a merely plastered prefabricated wall, this gives a particularly flat wall with a paper-finished surface.
  • the walls can even be provided with wallpaper or other decorative materials at the factory so that no additional work is required after setting up the prefabricated walls. This can save costs on the construction.
  • the prefabricated wall additionally has an external insulation, preferably an insulation with reinforcement.
  • the insulation may consist of insulating panels, which may be reinforced by a reinforcing fabric so that the finished wall on the outside is sufficiently stable.
  • the reinforcing fabric can be embedded between two mortar layers.
  • the advantageously simple and feasible in a short time proposed method for producing a finished wall described type with a wall body formed at least partially of concrete provides that the concrete is poured to form the wall body in a mold typically formed by a formwork, after which a mineral mortar for Forming a plaster layer is applied to the concrete, after which a fleece is applied to the plaster layer and is connected to this, which forms an inside of the finished wall.
  • the method is particularly easy to implement when the wall body in the mold in lying Orientation is formed.
  • the plaster layer and / or the fleece can then be applied to the wall body, if this is still in the mold. This allows a simple smoothing of the respective layer.
  • the plaster layer can be applied to the concrete before it is completely cured. Only the use of mineral mortar makes that possible. This avoids waiting times that would otherwise elapse until the concrete cures.
  • the nonwoven in turn, may conveniently be superficially embedded in the plaster layer before the plaster layer has cured.
  • the plaster layer is smoothed by machine after application.
  • a horizontal orientation of the resulting prefabricated wall so a quick and accurate smoothing of the wall is possible, for which it is e.g. It is sufficient to draw a smoothing rail only with a constant height over the plaster layer.
  • an insulation is inserted into the mold prior to the formation of the wall body and connected during the casting of the concrete with the resulting wall body.
  • a reinforcing layer can be formed there before the insulation is inserted into the casting mold, wherein the reinforcing layer is connected to the latter when the insulation is inserted.
  • the reinforcing layer may e.g. are formed by a reinforcing fabric between two mortar layers is embedded.
  • Fig. 1 shows process steps in the manufacturing process of a finished wall in one embodiment.
  • the finished wall is formed in a mold in a horizontal orientation.
  • an insulation 2 is introduced into the formwork element ( Fig. 1a ).
  • insulation 2 insulation boards are used as insulation 2 insulation boards are used. This insulation 2 forms after completion of the wall an outside 9 of the finished wall.
  • a plaster layer 4 is applied to the wall body 3 still lying in the casting mold 1 ( Fig. 1c ).
  • the plaster layer 4 is formed from a mineral mortar and is machine smoothed after application with a pulled over the plaster layer 4 rail.
  • a glass fiber fleece 5 is placed on the plaster layer 4 and partially embedded in this ( Fig. 1d ). At the time, the plaster layer 4 is not yet cured.
  • the fleece 5 covers the plaster layer 4 of the finished wall over the entire surface and spans it, possibly in several strips, a height of a floor in one piece.
  • the surface of the finished wall formed with the fleece 5 forms its later inner side 8.
  • Fig. 2 shows a further embodiment of a finished wall of the proposed type at the end of a corresponding manufacturing process, wherein the finished wall is still shown in the mold 1, ie before removing the formwork, and wherein recurring features are again provided with the same reference numerals. It differs from that on the basis of Fig. 1 described embodiment in that the insulation 2 is reinforced on the outside 9 of the finished wall.
  • mortar is brought as reinforcing compound 6 in the mold 1.
  • a reinforcing fabric 7 is placed on the reinforcing compound 6 and then another layer of reinforcing compound 6 is added to the casting mold 1, so that the reinforcing fabric 7 is embedded in the reinforcing compound 6.
  • Fig. 3 shows the finished prefabricated walls of the two described embodiments in an upright position after removal of the formwork.
  • Fig. 3a shows the finished wall of the embodiment Fig. 2 with the insulation 2 and with the reinforcing layer, which is formed from the reinforcing compound 6 and the reinforcing fabric, as well as with the wall body 3 made of concrete, the mineral plaster layer 4 and the web 5 of the inside 8 of the finished wall.
  • the outside 9 of this finished wall is formed by the reinforcing layer.
  • Fig. 3b shows the finished wall of the embodiment Fig. 1 in which no reinforcing layer is arranged on the insulation, so that the outside 9 of the finished wall is formed here by the insulation 2.
