- a further object is to provide a method for producing a concrete surface, in particular a concrete floor, in which the formation uncontrolled cracks due to setting or drying of the concrete largely avoided or at least controlled.
- Yet another object is to provide a method for the production of a seamless concrete surface, in particular a jointless one Concrete floor.
- the subject of the present invention according to a first aspect of the present invention Invention is thus a concrete surface, in particular a concrete floor, with a release layer disposed on a substrate and one on top of it arranged or applied top layer of concrete, wherein the release layer has a plurality of elevations and / or depressions, so that the thickness of the cover layer varies.
- concrete as used in the invention is very broad to understand and includes both concrete in the strict sense as well concrete-like hydraulic binder of all kinds, such. As cements, mortar or similar.
- concrete surface in the context of the present invention comprises concrete surfaces of any kind, both flat and uneven surfaces. Especially are hereunder concrete floors of any kind to understand.
- the separation layer a variety of elevations and / or depressions, so that the thickness of the concrete cover layer varied.
- the separating layer is repeated in preferably regularly recurring sections different Has thickness ranges. Consequently, this varies the thickness of the Concrete covering layer over the elevations or depressions of the separating layer, as described in more detail below.
- the use of a separating layer of the type described above inter alia to avoid uncontrolled Jointing or cracking in the concrete surface, in particular concrete floor, or at least causes the formation of controlled (micro) cracks or (micro-) joints in the concrete, in particular cracks or joints under 0.2 mm width, which are harmless from a structural point of view.
- the effect can be possibly explain the release layer provided according to the invention by that the release layer during drying of the concrete, cement, mortar or the like of the top layer absorbs shrinkage or evenly distributed over the area and, where appropriate, controlled for training (Micro) cracks or (micro-) joints leads. That will be later further explained.
- the provision or Cutting (fake) joints as required in the prior art is to be avoided.
- the elevations and / or depressions regularly distributed or arranged distributed over the separating layer are. In this way a maximum effect is achieved.
- the release layer has a structured, preferably uniformly structured surface.
- the release layer frustoconical or truncated pyramidal elevations (eg in the form of bumps, nubs, etc.), preferably in a more uniform manner Distribution.
- the separating layer provided according to the invention may be in particular a preferably structured film, in particular plastic or Metal foil, or act a preferably textured sheet. According to the invention it is preferred if the film is water-repellent or waterproof is formed, since it then additionally fulfills a sealing function.
- plastic films suitable according to the invention are structured (eg, dimpled) polyolefin films (eg, polyethylene or polypropylene films), as they are available for example in the trade.
- provided separation layer may in particular but also to a preferably structured or profiled (eg deep-drawn) sheet ("Profile sheet”) act.
- the separating layer can be formed by the substrate or can be the separating layer at the same time form the underground.
- the thickness of the topcoat over the elevations or depressions of the separating layer vary within wide ranges.
- the thickness of the cover layer varies over the elevations or depressions the separation layer on average by at least 5%, in particular by at least 10%, preferably by at least 15%, preferably at least by 20%, more preferably by at least 25%, especially preferably at least 30%.
- fibers in particular plastic fibers, such as polyolefin fibers (eg., Polyethylene or Polypropylene fibers), metal fibers, glass fibers or the like incorporated be.
- polyolefin fibers eg., Polyethylene or Polypropylene fibers
- metal fibers glass fibers or the like incorporated be.
- the material, the texture, the quantity and the dimensions of such Fibers depend on the particular application and are the person skilled in the art.
- metal or glass fibers serve as a bar steel or reinforcing steel reinforcement replacement
- plastic fiber for the purposes of fire protection or for the additional absorption of Forces from setting and early disappearance are used etc.
- the concrete surface according to the invention in particular concrete floor, is suitable both for indoor and outdoor use, especially for extensive floor areas (eg hall floor, roadway floor, runway for Aircraft or the like).
- the concrete surface according to the invention, in particular Concrete floor is generally resilient, especially passable.
- the concrete surface according to the invention in particular concrete floor, cast, in particular cast in one piece, before and is preferably formed monolithic and joint-free.
- a plurality of elevations or depressions having separating layer eg a "knobbed foil” or “studded plate" made of plastic or metal, a profiled or deep-drawn sheet metal etc.
- separating layer eg a "knobbed foil” or “studded plate”
- the separating layer effects this alike a kind of "gearing” with the ground (the concrete of the Cover layer or cover plate thus remains substantially on the same Place, d. H.
- this release layer prevents local shrinkage from being summed over greater distances.
- the permissible crack widths eg: 0.2 mm
- the big advantage of this is that you no longer need to view a test field two-dimensionally, but that one dimension is sufficient (eg: 1 x 30 m).
- the concrete surface according to the invention in particular concrete floor, is therefore based - in contrast to the conventional production monolithic or one-piece concrete floors (eg steel or fiber reinforced concrete floors), in between Supporting layer (substrate) and construction concrete (covering layer) one Slip film is inserted to allow for shrinkage the fact that the concrete is not given a chance to not to sum up preventing shrinkage movements over longer distances.
- conventional production monolithic or one-piece concrete floors eg steel or fiber reinforced concrete floors
- Supporting layer (substrate) and construction concrete (covering layer) one Slip film is inserted to allow for shrinkage the fact that the concrete is not given a chance to not to sum up preventing shrinkage movements over longer distances.
- the geometric shape of the dimpled films resembles a drainage foil, when out of a plane (under certain circumstances in raster-shaped module) surveys, for example in the form of z. B. truncated or truncated pyramids, burls, cones or like, stand out.
- Such dimpled sheets are commercially available.
- the mode of action of these nubbed foils is then that on the one hand built up against the substrate (base layer) a (higher) static friction
- the individual pimples become the (plate) thickness or thickness of the concrete of the top layer weaken and thus small-scale provoke harmless cracks.
- the static Effect of the final product may be explained as follows: If floors are made without joints, they fall at the top of the Concrete surface occurring at the joints tensile stresses according to outer Loads away (It can, for example, on known and usual design methods bedded plates.). At the top of the concrete surface Essentially only tensile stresses from constraining forces remain (Shrinkage, creeping, temperature, etc.), whose deformations in kind of many microcracks are compensated. The ones occurring at the bottom (Last) tensile stresses must be determined with the help of the residual body (within the dimpled foil) of the concrete - possibly with the help of the composite cross-section of the concrete with the dimpled foil - to be recorded.
- the heating coils When laying a planned floor heating, the heating coils can in the correct position and protected, without additional measures, between the pimples or depressions / elevations are introduced, if the nub module allows the inspection during concreting. (The ones through the heating coils partially interrupted transfer surface by fibers must be there be considered statically.)
- FIG. 1 and 2 schematically show a concrete surface 1 according to the invention, in particular a concrete floor, with a arranged on a substrate 2 Separating layer 3 and a covering layer 4 of concrete arranged thereon, wherein the separating layer 3 has a plurality of elevations 5 or depressions 6, so that the thickness of the cover layer 4 varies.
- a separating layer 3 may in particular be a dimpled foil (eg made of plastic or plastic) Metal) are used, the surveys 5, z. B. in the form of truncated pyramid or truncated conical bumps, burls or the like.
- These elevations 5 may be hollow, d. H. between the elevations 5 and the ground 2 is air (Fig. 1), or these surveys 5 consist of the interface material ("full nubs") ( Figure 2).
- the specially designed, provided according to the invention separation layer 3 prevents An uncontrolled joint or crack formation during setting or
- Subject of the present invention according to another, second Aspect of the present invention is a process for the preparation of the invention Concrete surface, in particular a concrete floor.
- Another The present invention thus relates to a process for the preparation a concrete surface, in particular a concrete floor, with one on one Substrate arranged separating layer, on which a cover layer of concrete applied (eg, poured), wherein as a release layer, a plurality used by elevations or depressions having separating layer is so that the thickness of the cover layer varies.
- the invention serves Method of avoidance or suppression or at least the control of joint and crack formation in concrete floors.
- the concrete surface being seamless is poured concrete and the concrete surface with alternating areas Lesser and greater thickness is poured, so that an uncontrolled Joint or crack formation is avoided or controlled (micro) cracks be formed in the concrete or the areas of lesser thickness Form micro or Sollrißstellen the concrete.
- alternating areas of lesser and greater thickness includes, for example, embodiments in which these areas in the Kind of egg carton vary, d. H. the areas of lesser thickness are not connected, but distributed as it were grid-shaped over the concrete surface In particular, each local area of lesser thickness is complete surrounded by a region of greater thickness. If necessary, the concrete surface but also be designed to be complementary.
