Definitions
- the invention relates to a covering material for direct connection to a concrete component, comprising a layer of at least one polymer having a first surface for conditioning and connection to the concrete component, said surface having a surface structuring, a concrete component with a covering material disposed on at least one component surface and a method for producing a concrete component, which is provided on at least one surface with a covering material, in which the concrete mixture is poured into a formwork and cured.
- Concrete components are provided with polymer layers for a variety of reasons.
- these polymer layers should on the one hand protect the concrete component itself from environmental influences in order to obtain a longer service life of this concrete component.
- threshold solders which must have sufficient elastic properties, the compressive stress of the ballast, especially in the contact area between see threshold and gravel, can be reduced because the contact surface is increased in so far as it allows the ballast grains, in this Schwellenhleohlung in the same way as in the case of wooden sleepers, which in themselves are already sufficiently “elastic” to allow the crushing of the gravel grains.
- These threshold solders but also as sound insulation elements, since they reduce the direct transmission of sound waves from the concrete sleeper in the ballast bedding.
- this elastomer mat has sufficiently good adhesion to the concrete component in order to prevent delamination.
- One way to achieve this is, for example, to glue the elastomer mat with the concrete component. However, it may happen that at higher temperatures, this adhesive layer softens and thus the adhesion of the elastomer mat is reduced to the concrete component.
- DE 202 15 101 U describes a railway sleeper with a concrete body and at least one elastic plastic layer arranged on the underside of the concrete body. Between the concrete body and this plastic layer is a random fiber layer, in particular a nonwoven layer, preferably a geotextile layer, arranged, which adheres to the concrete of the concrete body and is connected flat with the at least one elastic plastic layer.
- the fibers of this intermediate layer are used in order to achieve a mechanical anchoring via these fibers in the concrete component, whereby a micro-form closure is produced.
- a disadvantage is that a further layer is required for the arrangement of the elastomer layer.
- DE 10 2004 011 610 A describes a method for producing a composite system between concrete and a high-polymer elastic material.
- the high-polymer elastic material with a separately prepared provided geometric surface modification as a prototype, which is formed as nubby and / or rib-shaped elevations.
- the knob-shaped and / or rib-shaped elevations are formed into mushroom-shaped and / or T-shaped and / or bent elevations with a slight pressure by means of a hot forming tool. This gives the elevations in the upper area a larger diameter. So it is also connected with a multi-step manufacturing process.
- the object of the invention is to provide a way with which a covering material with a concrete component can be easily connected.
- the object of the invention is independent of the above-mentioned covering material, in which the surface structuring is formed by at least approximately channel-like and / or pore-shaped recesses or at least approximately channel-like elevations, further by the concrete component, which is provided with the covering material according to the invention and by the Method according to which the covering material according to the invention is connected to the concrete component solved.
- the advantage here is that the concrete in this, possibly continuous, i. not interrupted, channel-like or pore-shaped recesses or surveys can flow over a large area and thus a large surface is provided for the preparation of the compound. It is further advantageous that this covering material can be continuously produced, so that no further transformation steps or processing steps are required before the connection with the concrete component, whereby corresponding cost advantages can be realized.
- connection is essentially made by mechanical precautions on the covering material, so that with regard to the concrete component no consideration has to be given to special material compatibilities.
- a finished concrete component can thus be made available, which can be used immediately without further processing.
- the channel-like recesses can extend into the end face (s) of the covering material or it is possible for these recesses to be closed in the area of the end face (s), e.g. rolled together.
- the at least approximately pore-shaped recesses may have a mean diameter at the outer surface of the covering material, which is selected from a Range with a lower limit of 0.2 mm and an upper limit of 10 mm. It can thus be influenced by the adhesion of the covering material to the concrete component by selecting a pore size from this area accordingly. It is thus possible to provide for overuse of the covering material, that the connection point to the concrete component acts as a predetermined breaking point, whereby the lining material may optionally replace and thus the forces acting on this are not registered in the entire extent in the concrete component. For pores with a pore size below 0.2 mm in the region of the outer surface of the covering material has been shown that the concrete material flows only insufficiently into these pores. For pores with a diameter larger than 10 mm it could be observed that the adhesive strength decreases again. This is probably due to the fact that the area available for compound formation is reduced with increasing pores.
- the pores on this outer surface of the covering material have an average diameter which is selected from a range with a lower limit of 0.5 mm and an upper limit of 8 mm, in particular a region with a lower limit of 2 mm and an upper limit of 5 mm.
- an integral foam which according to a development in the region of the first surface, ie in the region of that surface where the surface structuring is provided, has pores with a large diameter. sen, whereas at the second, the outer surface, which is not intended for connection to a concrete component, no or very few pores or this surface is closed.
- Such an integral foam is characterized in that the density increases in the direction of the closed surface.
- the closed surface prevents the penetration of dirt and liquids into the covering material and thus prevents the weight of this covering material from being changed.
- the vibration behavior or sound damping behavior of the covering material being impaired by external disturbing influences.
- the density increase can change the vibration or sound damping behavior over the cross-section of the covering material, so that a wider spectrum of frequencies can be covered. It is thus also a non-positive and / or positive connection with the concrete sleeper possible.
- the at least approximately channel-like recesses in the region of the first surface ie the surface over which the connection to the concrete component is produced, can have an undercut thus produced a positive connection.
- the at least approximately channel-like recesses or elevations are interrupted in the direction of their longitudinal extension to form channel sections. It is thus also improves the connection formation to the concrete component, especially if in the case of channel-like recesses, the end faces also have an undercut, so for example in the form of "elongated pores" are formed or in the case of the channel-like surveys is thus additionally achieved that the concrete material easier to flow into these channels.
- the channel sections have a length which is selected from a range with a lower limit of 30% and an upper limit of 70% of the total length of these channel sections forming channel-like recesses or protrusions. It can also be achieved that in the case of possibly occurring defective connections, these are limited to a narrower range.
- these channel sections may have a length selected from a range with a lower limit of 35% and an upper limit of 65% of the total length of the channel-like recesses forming those channel sections, in particular a length that is selected from a range with a lower limit of 40% and an upper limit of 60% of the total length.
- these channel pieces may have a length which is selected from a range with a lower limit of 1 mm and an upper limit of 100 ⁇ m. It is also possible that these channel sections have a length which is selected from a range with a lower limit of 10 mm and an upper limit of 80 mm, in particular selected from a range with a lower limit of 20 mm and an upper limit of 50 mm.
- the at least approximately channel-like recesses or elevations may be formed in the manner of a tube profile extending at least approximately parallel to the surface.
- the inflow of the concrete material is increased and the degree of filling of the channels is increased, on the other hand, in the embodiment "elevation”, a kind of loop formation or positive connection is achieved, so that the poured concrete material covers large areas in the area of these channel sections
- a further improvement of the connection system, ie the pull-out strength of the covering material, is achieved with this variant embodiment.
- the at least approximately channel-like recesses in the manner of a tube profile may have a height above the surface of the layer which is selected from a range with a lower limit of 2 mm and an upper limit of 20 mm. Below 2 mm, the channels in the case of the surveys on too small a diameter, whereby the inflow of concrete material is in turn difficult.
- At least some of the at least approximately channel-like recesses or elevations may have a different height from the further at least approximately channel-like recesses or elevations of the covering material, whereby venting during the introduction of the concrete material onto this covering material is facilitated.
- a second, the first surface opposite surface of the layer is also formed with a surface structuring, so on this further surface another concrete component can be connected to this covering material, and thus the covering material as a buffer between these two concrete components can work.
- this lining material has a density gradient with increasing density in the layer interior of the covering material.
- the at least approximately channel-like recesses or elevations may also be arranged distributed in a zigzag-shaped and / or arcuate or wave-shaped manner over a first and / or second surface in addition to a linear design at right angles to an outer side edge ,
- a kind of checkerboard pattern can be formed between the elevations and the channel sections, in that the channel sections run at least approximately at right angles to the elevations.
- the channel sections have a relative to the surveys history, which is different from 90 °, eg selected from a range with a lower limit of 10 ° and an upper limit of 85 °, in particular from a range with a lower limit of 20 ° and an upper limit of 75 °, for example selected from a Range with a lower limit of 30 ° and an upper limit of 65 °. It can thus be varied according to the distribution of forces in the connection area covering material / concrete component.
- elevations and / or recesses may just aur rub these bounding sidewalls.
- at least individual, preferably all, of these side walls are cambered.
- the at least approximately channel-like recesses or projections may have a round, oval, mushroom-like, T-shaped, triangular, have quadrangular or polygonal cross-section.
- the covering material may be formed of an elastomer or a thermoplastic. It is thus a corresponding adaptability for a variety of uses of the covering material possible.
