Definitions

  • the invention relates to a method for producing heavy-duty floors, in particular industrial floors, by laying fresh-on-fresh a hard material mortar layer on a concrete layer spread out on prepared ground.
  • Highly wear-resistant concrete floors are produced in several successive work steps according to the previously customary processes.
  • the concrete layer is often deaerated and thus compacted using Vacuum.
  • An adhesive bridge is then applied to the concrete layer in accordance with DIN 18 560, T.5, 5.4.
  • the transition layer is applied to this.
  • Finally, the top hard material layer is applied as a wear layer in a DIN-compatible composition depending on the intended type of stress on the floor.
  • a process is known from DD / PS 209224 which increases the pressure and wear resistance of the hardened cement screed of prefabricated hard aggregates by largely avoiding the formation of interfaces and fine grain accumulations on the mortar layers to be applied.
  • a rigid to very rigid lower layer of mortar is loosely applied to a base layer and leveled.
  • a rigid to very rigid cement-bound hard mortar layer is loosely applied in a required thickness and also leveled.
  • the two layers that have not yet set are then compacted in one operation to form an inhomogeneous hard-hardened cement screed. Due to the surface roughness of the leveled lower mortar layer and the joint compaction of both layers that have not yet set, a toothing is created which increases the area available for the adhesion of the layers.
  • the multilayer floors produced according to the prior art tend to crack, hollow spaces and premature detachment of the hard or transition layer from the substrate.
  • the reasons for the break-offs and outbreaks are almost exclusively due to the fact that the individual layers adhere to one another by adhesion or interlocking.
  • the interlocking produces a dowelling effect at the interface between the lower mortar layer and hard mortar layer, but this bond is also not strong enough to prevent premature soil destruction.
  • the invention has for its object to propose a method with which a floor with an intimate bond of the individual layers and can be produced with longer liability even under high loads and larger temperature differences.
  • a coarse-grained mortar is spread onto the concrete layer immediately after it has been laid and into the dough Concrete layer is rubbed, whereupon a mixture of cement and hard material is spread on the intermediate layer thus formed and rubbed fresh-on-fresh, the proportion of cement, starting from the concrete layer laid first, being increased from layer to layer.
  • the compulsory mixing on the fresh concrete surface has the consequence that no cracks or flaking, breakouts or the like can occur as a result of the layering.
  • Another advantage of the method according to the invention is that the concrete can be produced in one go without interruption.
  • the layers of the subsequent layer are applied as soon as the previous layer has been worked out but is still doughy in order to absorb the material of the subsequent layer in its surface area and thus effectively anchor it.
  • the coarse-grained mortar for the intermediate layer is preferably pasted with water. This makes it easier to spread on the concrete layer.
  • a coarse-grained mixture component in particular minerals such as quartz sand, corundum or slag from metallurgical processes, with a grain size of approximately 3 to 10 mm, preferably 5 to 6 mm, is to be added to the mortar for the intermediate layer.
  • the grain size of the coarse-grained mixture component is expediently determined so that it corresponds to the desired thickness of the intermediate layer, ie that it is about as large as the thickness of the intermediate layer. In this case, the grains of the mixture component are able to securely anchor the subsequent hard material layer.
  • the proportion of cement in the intermediate layer should have a ratio of approximately 1: 2 to 1: 3 to the proportion of solids.
  • the proportion of cement in the coating should expediently be increased in a ratio of 300: 500: 700 from bottom to top. If the proportion of cement in the concrete layer is 300 kg / m3, the proportion of cement in the intermediate layer should be 500 kg / m3 and that of the top layer of hard material 700 kg / m3.
  • the concrete layer is expediently spread out to a thickness of 10 to 20 cm, the intermediate layer to a thickness of 3 to 10 mm and the hard material layer to a thickness of 6 to 20 mm.
  • the concrete layer is preferably vacuumed.
  • the time for the setting of the concrete is reduced accordingly and the density of the concrete layer is increased.
  • the hard or wear layer can consist of terrazzo-colored or synthetic mortar layers.
  • the surfaces can be made rough, non-slip, but also smooth, dust-free and non-dusting.
  • a concrete layer 2 is poured onto a substrate 1 in the usual way.
  • a layer of mortar 3 is spread onto the concrete layer 2, which contains coarse grains 4 of a mixture component and cement and is pasted with water.
  • the layer 3 is incorporated into the concrete layer 2.
  • the result is indicated in Fig. 3.
  • the layer 3 is mixed with the material of the concrete layer 2 and forms a surface zone 3 ⁇ in which the coarse grains 4 are stored. In this state, the concrete layer is uniformly monolithic.
  • the hard material layer 5 is then spread out on the concrete layer 3 according to FIG. 3 according to FIG. 4. It consists of spattery or spherical hard material grains, mixed with cement and pasted with water.
  • the hard material layer 5 is worked into the top layer 3 ⁇ of the concrete layer 2, ie mixed with it. 5, a monolithic concrete layer 2 on the substrate 1 with a surface layer 3 dem, in which the intermediate layer 3 and the hard material layer 5 are contained anchored to one another.
  • the surface layer 3 ⁇ is cross-hatched. Even in this state of production, the concrete floor has a monolithic structure.
