Definitions

  • the invention relates to a method of producing a terrazzo floor and a terrazzo floor.
  • Terrazzo floors are locally manufactured, seamless floor coverings. Traditionally, these terrazzo floors are made using limestones and cements, aggregates, such as natural stones - soft and hard rock - of all kinds and aggregates in different colors.
  • the terrazzo floors are used in residential buildings, entrance halls of public and private buildings, canteens and hospitals, shopping centers, pharmaceutical companies and similar.
  • the terrazzo floors are usually applied to load-bearing concrete slabs or floor slabs whose concrete strength corresponds to at least one grade B 25 concrete, however, application to insulating layers, intermediate layers or other floors is possible.
  • the surfaces are prepared by cleaning soiling and loose components. If necessary, a primer to achieve a uniformly absorbent surface or to realize a bonding.
  • Traditional cement-based terrazzo floors are artificially limited by separating rails, otherwise the terrazzo floor tends to crack.
  • the terrazzo floor is traditionally applied with a terrazzo tile, the height of the job being approximately 15 mm to 40 mm.
  • the fresh flooring produced in this way is rolled.
  • the rolling serves to compact the fresh flooring.
  • the surface is machined by grinding using grindstones of different grits and diamond-tipped tools. In the surface processing by grinding about 3 mm to 5 mm of the surface are sanded. After cleaning, remaining pores are closed with a suitable filler and sanded after curing. This entire implementation of the soil preparation is very time-consuming.
  • the publication DE 199 18 598 A1 discloses a method and apparatus for making a terrazzo floor and a composition for a floor made in the form of a seamless, especially colored floor covering from a mixture of aggregates and binders.
  • the mixture is mixed in a mixing device with water such that it is flowable and pumpable.
  • the flowability of the batch on the subfloor causes an approximately flat surface of the facing layer.
  • the densification of the introduced facing layer is carried out by self-compression under the action of gravity.
  • a pigmented plastic floor with natural stone effects produced on the basis of synthetic resin and aggregates customary for synthetic resin floors, which is produced in a layered structure.
  • an epoxy resin layer is applied, which is mixed with fillers and additives, but not with the pigmentation mass.
  • the pigmentation mass is applied. Wherein the pigmentation mass is integrated at least to a large extent superficial. However, sedimentation does not take place in this case, rather only a slight penetration into the base layer is desired.
  • the application of a cover layer made of a conventional synthetic resin Particularly preferably then the created plastic bottom surface is ground.
  • a grinding takes place up to the depth in which as a result of sinking only one enriched with the pigmentation mass surface is present. In this way, so much is abraded until coarser structures are exposed.
  • Betonit it is possible to further reduce the sedimentation so as to prevent too deep penetration of the pigmentation mass into the base layer.
  • a method for the production of terrazzo floors known.
  • a mixture of different sands or glass or mosaic stones, as well as color pigments or pastes with an epoxy resin or the like prepared in place and applied to a prepared floor.
  • a primer is first applied to the prepared raw concrete with a lambskin scooter, wherein the uncured primer is sprinkled with a quartz sand of grain size 0.8 mm.
  • the mixture or the mixture of the different sands or other additives together with the further addition of epoxy resin or a comparable plastic can be applied to the primer and distributed.
  • a problem with the known arrangements and methods is that the methods and compositions used in the prior art are not suitable for achieving large areas throughout with a terrazzo floor with the traditional appearance.
  • the known methods and compositions are documented with negative properties, so that in particular pore formation is a major problem.
  • the crack resistance of the terrazzo floor produced is not guaranteed since the prior art methods and compositions for producing a terrazzo floor tend to crack.
  • Another disadvantage is the great amount of work and time required to produce a terrazzo floor using the methods and compositions known in the art.
  • the present invention has for its object to provide a manufacturing method and a terrazzo floor, with which an easy to create, maintenance-free and low wear underlying terrazzo floor can be made with a traditional look.
  • a terrazzo floor is also designed for high laying and processing speeds and withstands high forces and loads, in particular its permanent crack resistance is ensured, especially on large areas.
  • a high cost saving in contrast to the known terrazzo soil production method is particularly advantageous.
  • the classic terrazzo-floor look is due to the high packing density of the sedimenting rock granules and on the other hand by the grinding of the surface achieved, so that overall the structure of a classic terrazzo soil arises.
  • the distribution of the polymeric plastic can be done by a toothed spatula.
  • the rock granulate density can be both homogeneous and decrease from top to bottom.
  • the high crack resistance is also realized in that the lower region has a lower rock granulate density in a section through the terrazzo soil and thus there is a lower packing density of the rock granulate in the lower region.
  • a continuous bottom layer consisting of the polymer plastic is created in the lower area.
  • a more uniform plastic layer is realized, which has fewer approaches to break points, since the bottom of a Terrazzo floor is often the starting side for cracking.
  • the underside of the terrazzo floor is now not weakened by the incorporation of granular rock, a high crack resistance of the entire terrazzo soil is formed. In particular, air pockets on the sides of the rock granules facing the ground are prevented, since the rock granules sediment into the polymer plastic.
  • the granular rock is coated with preferably the same polymeric plastic, in particular no curing of the polymeric plastic before application, a better matrix connection between the applied uncured polymeric plastic and with A granulated material which is enveloped in a polymer plastic can be achieved, since the introduction takes place "wet on wet". It is ensured that the granular rock is completely enclosed with the polymer plastic, so that there is a consistent contact between granular rock and the polymeric plastic.
  • the binder matrix is further optimized.
  • the introduction behavior of the rock granules which is poured up can be varied.
  • an improvement in crack resistance or crack arrest within the terrazzo floor can be achieved.
  • pre-bedding granular granules on the not yet cured polymeric plastic, wherein the pre-bedding granular granules preferably has a higher specific gravity than the granular rock, the pre-bedding granules sedimented more in the polymeric plastic, whereby higher layer structures are possible, which have a corresponding high crack resistance.
  • Such pre-scattered rock granules may be, for example, known aggregates of a heavy concrete, such as barite, ilmenite, magnetite, hematite or heavy metal slags. Furthermore, however, known additives for radiation protection concretes can also be used.
  • the rock granules are not homogeneously distributed and embedded in the polymer plastic, but the density of the rock granules is highest on the free surface within the polymer plastic.
  • a terrazzo floor designed in this way preserves the look of traditional terrazzo floors and also has sufficient compaction.
  • the durability of the terrazzo floor is superior in crack resistance, which is higher than that of the arrangements known in the art, especially considering the traditional terrazzo floor look.
  • the adhesion of the plastic increases with the rock granules within the matrix.
  • the improved adhesion results in further maximizing the durability of the terrazzo floor.
  • To increase the optical value of the rock granules can be wrapped with a different colored polymeric plastic, so that during later sanding a contrasting border around the respective rock forms.
  • Particularly interesting here are combinations of complementary colors and color combinations with one high contrast ratio, wherein the selected granular rock color and the selected color of the polymeric plastic are included in the choice of the color of the enveloping polymeric plastic.
  • the plastic compound is further improved because the plastic hardens evenly as a total batch.
  • the polymeric plastic is a low-viscosity epoxy resin, which is transparent or pigmented, in particular, it is yellowing. Particularly advantageous is the color fastness of the terrazzo floor, when the plastic is formed yellowing.
  • the optics and thus a certain value is adapted to the traditional terrazzo soil. It makes sense, as is customary in traditional terrazzo, to adjust to certain bandwidths of rock granules. For the longevity within this total terrazzo-soil arrangement, a restriction to a smaller granular rock size range is not necessary, so that the spectrum from 1 mm to 30 mm can be exploited.
  • the range of 2 mm to 14 mm and particularly preferably the range of 2 mm to 6 mm rock granulate size is used, since within these ranges a very high packing density is achieved, which leads to a very low total assembly height of only a few millimeters.
  • the height of the terrazzo floor is in the range of 6 mm to 20 mm and in this area depends only on the removed material or the desired optical effect.
  • the polymeric plastic has rock flour with grain sizes between 0 and 0.125 mm and / or ultrafine granules with grain sizes of up to 1 mm, the flowable plastic is better distributed on the substrate to be coated with the terrazzo soil.
  • rock flour and / or ultrafine granules in the total mixture is a weaker, with greater rock flour and / or Feinstgranulatanteil, or even stronger, with less rock dust and / or Feinstgranulatanteil, sinking of the Gestränranulates in the total mixture of plastic and rock flour and / or ultrafine granules.
  • the polymeric plastic comprises polyethylene fibers
  • the basic strength of the plastic is increased.
  • the floor structure can be carried out in even thinner layer thicknesses without a reduction in crack resistance.
  • rock granules to be scattered are individually adaptable.
  • Application of specific rock granule mixtures in well-defined soil sections results in individualized patterns within the overall terrazzo soil. After curing, the entire terrazzo floor can be sanded without taking into account the different sections, resulting in an outstanding overall result.
  • Such sections may for example be lateral boundaries of tracks or the like., Which are later clearly visible by admixed color additives.
  • the fibers may be contained in the rock granules or preferably partially contained in the plastic and partially applied before applying the rock granules on the already applied plastic or be included in the plastic already.
  • Particularly advantageous is the use of carbon fibers in the overall arrangement. The use of these carbon fibers results in an electrical conductivity of the overall floor structure, so that the floor can also be used in electrically sensitive areas, for example in operating theaters.
  • Fig. 1 is a schematic section through the entire bottom structure of a terrazzo floor shown.
  • This terrazzo floor 1 consists of a polymer plastic 11 and a rock granulate 12 located therein.
  • the density of the rock granulate 12 is greatest at the surface O of the terrazzo bottom 1 and decreases with increasing depth, as viewed from the surface O.
  • the floor 2 may here be a floor slab of concrete or reinforced concrete, wood, or the like or in particular a screed.
  • the floor can also be insulation, whereby in this case particular attention must be paid to a uniform sinking behavior of the insulation.
  • Extruded polystyrene is preferably used here, the transitions being correspondingly improved with a fabric, or alternatively the entire floor consisting of insulation being provided with a fabric fleece.
  • the screed is preferably a surface-ready anhydride screed on the insulation, the impact sound insulation or directly on a raw floor, it is unimportant whether a simple prior art to be taken screed or designed for underfloor heating and provided with a corresponding floor heating screed use place.
  • the floor 2 to be occupied is prepared.
  • the removal of coarse impurities, soils, such as oils or fats is well known in the art and is performed first. After cleaning the bottom 2 of coarse impurities it is then freed from dust and dirt. With a sufficiently smooth and leveled bottom 2, the preparatory work on the bottom 2 is completed at this point. In particular, can be dispensed with a primer in the rule. If the floor 2 is not sufficiently leveled, this can be improved, for example, by a leveling mass or face milling. Alternatively, the floor, which is not sufficiently leveled, can be compensated by correspondingly more plastic in the further process. In this case, the soil situation must be considered economically from case to case and calculated according to the insufficient leveling, whether it is better to prepare the soil in an additional step and to level it accordingly with more plastic mass.
  • the flowable polymeric plastic 11 is applied to the prepared bottom 2. This can be done by simply pouring the preferably 2-component polymeric plastic on the floor. The application can be done simultaneously by several workers or sections. For this purpose, for example, with appropriate trowels, a pre-distribution of the polymer plastic can be performed.
  • the flowable polymeric plastic 11 spreads by itself on the prepared bottom 2 by deliquescence. After the polymeric plastic 11 has spread itself either partially or completely by deliquescence, the rock granules 12 is applied to the not yet cured polymeric plastic 11. This application can be carried out either in sections, in analogy to the application of the flowable polymeric plastic 11 or over the entire surface.
