Definitions

  • the invention relates to the use of a covering material for direct, positive connection to a concrete component, comprising a layer of at least one polymer having a first surface for engagement and connection to the concrete component, this surface having a surface structuring.
  • 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.
  • 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.
  • this describes the DE 202 15 101 U a railway sleeper with a concrete body and at least one elastic plastic layer arranged on the underside of the concrete body.
  • 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 anchorage via these fibers in the concrete component, whereby a microforming connection is formed.
  • a disadvantage is that a further layer is required for the arrangement of the elastomer layer.
  • the DE 10 2004 011 610 A describes a method for producing a composite system between concrete and a high polymer elastic material.
  • a method for producing a composite system between concrete and a high polymer elastic material by injection molding or by pressing the high polymer elastic material with a separately prepared geometric surface modification provided 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. It is therefore also in turn a multi-step manufacturing process ally.
  • the DE 200 14 999 U1 describes a concrete sleepers for track construction in which a concrete body and an existing of a high polymer material elastic plate material are adjacent to each other and connected to each other.
  • the plate material is positively connected by means of a geometric surface modification with the concrete body.
  • the geometric surface modification is formed by projecting nubs.
  • the EP 0 049 879 A1 describes a rubber boot, wherein in the threshold facing surface of this threshold shoe recesses are formed. These recesses may be channel-like or there is the possibility that the recesses are formed next to elevations, which are formed knob-shaped or with a square cross-section.
  • the EP 0 105 950 A1 describes a mat of elastic material for use under a ballast bed, this mat having at the top a sheet whose hardness and elasticity are such that the ballast can not penetrate into the mat. Nubs, protrusions or the like may be provided on the underside of the mat.
  • the DE 35 24 719 A1 describes a protective layer for an elastic track bed mat, which is arranged under a ballast bed and consists of a single or multilayer web of elastomeric materials, wherein the web has cavities and / or nubs.
  • a protective layer is arranged, which consists of a nonwoven fabric, a fabric made of an elastomer or a rubber-like plastic whose extensibility and crushing resistance are chosen so that penetration of the ballast does not destroy the mat leads.
  • the EP 0 833 008 A1 describes a foot plate for a railway sleepers made of concrete.
  • a support plate is arranged, the top, which is enclosed in the concrete, provided with means of anchoring in the railway sleeper and with discharge means for air, which is trapped in the railway sleeper during the casting of the concrete, and on the other hand, a coating made of elastomer, which is connected to at least the underside of the plate.

  • the advantage here is that the concrete in this, optionally continuous, ie not interrupted, channel-like recesses or surveys can flow over a large area and thus a large surface for the preparation of the compound is provided. It is further advantageous that this covering material can be produced continuously, 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 are.
  • connection is essentially made by mechanical precautions on the covering material, so that with regard to the concrete component does not have to be taken into account for special material tolerances.

  • more than two bumps 6 form a group, e.g. Three or four, and it is also possible that the distances of the surveys 6 within a more than two surveys 6 having group are also different.
  • the groups of elevations 6 can also be arranged at completely irregular intervals from one another.
  • the concrete can penetrate due to the small distances between the elevations 6 of a group at different speeds in the interstices of the elevations 6 and in the channels 7 of the recesses 8, wherein the smaller distances 22 between the elevations 6 of a group later and / or slower filled with concrete, whereby a ventilation system is achieved to escape the trapped air during concreting.
  • a width 24 of the web-shaped elevations 6 may be selected from a range with a lower limit of 1 mm and an upper limit of 10 mm, in particular be selected from a range with a lower limit of 2 mm and an upper limit of 7 mm.
  • the distance 22 between the bumps 6 of a group can be selected from a range with a lower limit of 0.5 mm and an upper limit of 10 mm, in particular selected from a range with a lower limit of 1 mm and an upper limit of 3 mm.
  • the distance 23 between the groups of protrusions 6 may be selected from a range with a lower limit of 2 mm and an upper limit of 20 mm, in particular selected from a range with a lower limit of 3 mm and an upper limit of 7 mm , Distances greater than 20 mm reduce the adhesive surfaces to the concrete, which may decrease the adhesive strength of the adhesive system.
  • the distances 22 and 23 can be made for example by appropriate shapes or by subsequent milling of the full material.
  • the recess 8, i. Channels 7 can be made by subsequent drilling or milling of the elevations 6 or preferably by a correspondingly shaped nozzle of an extrusion die.
  • Fig. 20 shows a cut through the channels 7 top view of a covering material 2, that the channels 7 are arranged in a different angle to the elevations 6 to 90 °.
  • the angle may be selected from a range with a lower limit of 10 ° and an upper limit of 85 °.
  • Fig. 21 shows a covering material 2 in side view with elevations 6, the side walls 25 have, which have a crown, whereby the force fit is improved to the concrete.
  • the radius of the crowning may be selected from a range with a lower limit of 1000 mm and an upper limit of 10000 mm.
  • the elevations 5 recess 8 (not shown).
  • two elevations can form a group in this variant, although a symmetrical design of the elevations 6 without grouping is possible, so that, for example, a survey 6 may have two cambered side surfaces 25.
  • the crowning can also be formed only on one of two side surfaces 6, for example, only the respective right or left side wall 6, or can also be formed hybrids in which, for example, each two adjacent side walls 25 a crown and the adjoining side walls are currently running. It is also possible to provide different crowning radii both within a crowning and between crowns of two elevation 6.
  • the execution of the covering material 2 after Fig. 22 - Illustrated in front view has a crown on, but in the surface 4, which comes to the concrete threshold to the plant. It is thus also achieved a better ventilation for the trapped air during concreting.
  • the crowning may also be present on the surface of the elevations 6, which comes to rest against the concrete. This surface is above the surface 4, over which protrude the projections 6.
  • the at least approximately channel-like recesses 8 here have a different diameter, which is larger at the centrally arranged channels 7 than at the marginal formed channels 7. There are also more than two mutually different diameter of the channels 7 possible.
  • the channels 7 in the execution of the covering material 2 after Fig. 23 the same diameter, but the channels are not arranged at least linearly as after Fig. 22 but follow the course of an arc.
  • Fig. 24 shows a covering material 2 in front view, which as an example of a possible surface modification - viewed in cross section - wavy profile, creating a larger surface for connection of the concrete - in addition to the at least approximately channel-like recesses 8 - is created.
  • the covering materials 2 after the FIGS. 22 to 24 can also be provided with elevations 6 (not shown), as to the Fig. 18 to 21 has been described.
  • Fig. 25 a variant of the invention, with which it is possible to provide larger widths of concrete surfaces over the entire surface with the covering material 2.
  • the covering material 2 has a groove 27 on a first edge region 26 and a spring 29 on a second edge region 28 lying opposite the first edge region. It can be used to connect a plurality of covering materials 2 via the groove 27 - spring 29 - connection to a larger area element.
  • a covering material 2 each have 2 grooves 27 and another covering material 2 has two springs 29, but the asymmetrical design with groove 27 and spring 29 is preferred because only one form or (extrusion) Nozzle is necessary.
  • the groove 27 and the spring 29 may be formed over the entire longitudinal extent of the covering material 2.
  • tongue and groove connection and other connection means may be provided.
  • this covering material 2 can preferably be carried out by a continuous process.
  • these are pressing methods, injection molding methods, extrusion methods or automatic vulcanization methods. Since these methods have already been adequately described in the prior art, reference should be made at this point to the relevant literature, for example Röthemayer / Sommer; Rubber Technology Materials - Processing - Products; Hanser, 2001, especially chapters 10 to 12.
  • the production of the composite system 1 can now take place in such a way that, for example, for the embodiment variant threshold a corresponding formwork is provided which gives the threshold the outer dimensions.
  • the covering material 2 is inserted and then poured into the liquid concrete mass and cured.
  • the viscosity of the concrete mass should be adjusted so that it is siclieravi with sufficient certainty that the concrete flows into the recesses 8 and 7 channels. A shaking of the introduced concrete for compression and expelling trapped air is possible.
  • the covering material 2 with the ventilation openings i. e.g. Recesses 17, or ventilation systems - as described above- is equipped and if the bottom of the formwork may also have vents.
  • the thickness of the covering material 2 is preferably chosen for the embodiment variant threshold soling so that a deflection of 1 to 1.5 mm is achieved.
