Definitions

  • the invention relates to a roll-up drainage membrane for the production of capillary-breaking drain layers for Drainage of coverings laid on them, consisting of a roll-up water-permeable cover sheet on which perpendicular to the longitudinal direction of the web in parallel distance and thus in the space cross drainage channels forming strips made of foamed plastic material are attached adhesively, each with one Number of right angles across the foam plastic strips extending, in a flat side of the Stripes forming open longitudinal drainage canals Recesses are provided, which have a depth, which is less than the height of the foam plastic strips is.
  • Such rollable drainage sheets are from the applicant have been developed (EP-0 178 382 A1), in which by the Spaces between the transverse to the longitudinal direction strips or slats attached to the underside of the cover sheet made of rigid foam plastic, transverse drainage channels and by a variety of from the cover sheet opposite, i.e. the one on the underground flat sides to be attached from cut into the strips, only over part of the height of the foam plastic strips extending recesses in the longitudinal direction of the web running drainage channels are formed.
  • Such rigid, non-rollable drainage plates have themselves due to their light weight and extreme inexpensive manufacturability in the manufacture of capillary-breaking drain layers in private use Area, i.e. on private balconies and terraces proven. However, they are not suitable for the production of Drain layers under heavily used areas, e.g. parking area, since the plastic profile walls from one certain weight load tend to buckle.
  • the drainage plates are reasonable for transport reasons always made in a limited size, so that the laying of a balcony or terrace usual size with such drainage plates still in reasonable time is possible to lay out a larger one Area, such as a flat roof or a parking deck, with such relatively small drainage plates, however took much more time than rolling out one long roll-out drainage membrane.
  • the channel system formed by the longitudinal and transverse drainage channels serves both for the removal of penetrated surface water and for ventilation and thus drying of the superimposed structure to be drained.
  • This known roll-up drainage membrane has proven itself for those applications in which the loads occurring are kept within a certain range. Due to the requirement of a perfect water drainage, which can of course only take place in the areas of the cover sheet which are not covered with the foam plastic strips running across the width of the cover sheet, the strips must be arranged at a distance on the underside of the cover sheet, which approximately is equal to the width of the stripes.
  • the contact area of the foam plastic strips on the subsurface ie the surface area stressing the seal
  • the load to be transmitted to the ground via the contact area of the foam plastic strips is accordingly concentrated and increased in the area of the contact areas.
  • the total load of approx. 300 to 400 kg / m 2 is distributed over only 40 to 42% of the total area , which leads to a two-and-a-half-fold increase in the surface pressure on the seal, which in the current designs generally consists of bituminous substances.
  • sealants are thermoplastic react, and with increasing temperature (under drained Coverings, e.g. under red colored surfaces on thermally insulated Roof terraces up to 55 ° C warm).
  • under drained Coverings e.g. under red colored surfaces on thermally insulated Roof terraces up to 55 ° C warm.
  • the well-known drainage membrane it can therefore Areas that are significantly heavier than balconies and terraces, e.g. for parking deck areas, the loads from the motor vehicles driving over are exposed to impressions, which up to one Damage to the sealing materials, e.g. bituminous welding tracks, to lead.
  • the invention has for its object one with little Easily processable, capillary breaking roller drainage to create the largest possible drainable Has area and at the same time has a very large contact surface, which means that also suitable for higher loads on the area to be drained is.
  • this object is achieved in that the Foam plastic strips with the flat side on the cover sheet in which the longitudinal drainage channels are open, and that the cover sheet in the between the Longitudinal drainage channels lying areas of the flat side is glued to the foam plastic strips.
  • the cover sheet side drainable area is significantly enlarged is because water passes through the cover sheet only on the between the the drainage channels forming recesses remaining flat side areas is disabled.
  • the cover sheet is expediently somewhat wider than the length the foam plastic strip sized, and the strips are flush at one end to the long side of the cover sheet aligned glued on this so that the cover sheet on the opposite long side in a stripe-shaped Area over the ends of the foam plastic strips survives and in this area with the side adjoining Drainage membrane can be overlapped.
  • the cover sheet on at least one End in one of the widths of at least one foam plastic strip appropriate length not with foam plastic strips to be provided and so the overlap in this area with the subsequent drainage membrane.
  • the cover sheet is expediently made of a non-woven or grid fabric material manufactured, preferably one rot-resistant material, although in certain applications also decomposing over time Nonwovens, grid webs or fabrics are used can. With hardened screed coverings, it is sufficient, for example, if the material of the cover sheet as long is stable until the screed layer applied to it hardened and thus inherently stable.
  • Foam plastic strips can also be a heat and / or a sound-absorbing layer can be adhered, which also protects the seal against pressure-related Protects impairments and those acting on the seal Thrust of the covering lying thereon, the expand or contract at changing temperatures can, diminishes.
  • the foam plastic strips can each cover their entire Length can be one-piece strips, or they can be made from at least two shorter, aligned at the joint strip sections glued to the cover sheet be composed.
  • the ratio of the width of the drainage channels forming spaces between adjacent foam plastic strips is useful in the range between two 2: 8 and 1: 9 selected. This makes a comparative maintain a large support surface for the drainage membrane on the subsoil, without the possibility of rolling up the drainage membrane impaired for the purpose of storage and transportation would.
  • FIGs 1 and 2 there are two different options the construction of floor structures in the outdoor area, for example balconies, terraces, parking decks and others surfaces to be dewatered, which using the following in connection with Figures 3 to 6 still Drainage sheet 10 according to the invention described in more detail capillary-breaking be drained.
  • Figure illustrates 1 the application of the drainage membrane 10 for drainage a covering laid on a cement screed layer 18 of tiles 19.
  • the cement screed 18 is directly on the drainage membrane 10 applied, which in turn on a bituminous waterproofing membrane 21 which rests on the foundation 22 seals against water.
  • the foundation 22 or one separate layers applied to it indicate the Top of a slight slope to get up to the waterproofing membrane to let out any water that has penetrated.
  • the use of the drainage membrane illustrated in FIG. 2 10 differs from the previously described application in that the covering of Loosely placed plates 20 directly on the drainage membrane 10 is formed.
  • the drainage sheet 10 itself is made from a cover sheet 13 a - preferably - rot-resistant bending switch and water permeable material, such as a Non-woven material made of plastic fibers, on the underside at regular intervals foam plastic strips 11 made of rigid foam, e.g. foamed polystyrene, in Transverse direction are glued at a short distance.
  • foam plastic strips 11 are on the cover sheet 13 facing flat side with a plurality of in the longitudinal direction the cover sheet extending recesses 12, which run across the entire width of the strips 11 and in this way form longitudinal drainage channels.
  • the drainage sheet 10 according to the invention can be produced in very long rollable sheets. Areas up to 50 m 2 or more can be laid out very efficiently on a single roll on large parking decks, green underground parking decks or on green roofs in the shortest possible time.
  • the foam plastic strips 11 provided at the front and rear ends can have, in the manner shown in FIG. 4, lateral recesses 16 on their free long sides, which are open at the bottom and towards the long side. Adjoining strips 11 of the ends of successive drainage sheets 10 form in the area of the lateral recesses 16 drainage transverse channels into which the water flowing in via the recesses 12 forming the longitudinal drainage channels can be discharged laterally.
  • a heat and / or sound-absorbing layer 17 can also be laminated, which is only indicated in FIG can be.
  • Coverings laid on the drainage membrane break capillaries drained so that e.g. for covering structures made of tiles with cement screed outside frost damage and efflorescence be excluded with certainty.
  • the permeable surface of the cover sheet between the Recesses in the flat side of the cover sheet facing the Foam plastic strip 11 is particularly large, namely in practice 20 to 30% larger than previously known Products, thus ensuring optimal water drainage from covering layers laid over it.
  • the footprint of the drainage sheet according to the invention are so large that it is opposite (not drained Coverings) only to a minimum and therefore negligible Pressure increase on the underlying seal is coming.
  • the risk of the seal being pressed in under load is therefore also on heavily used surfaces, e.g. Parking decks, no longer exist.
  • the water-permeable cover layer with filter effect both the pollution of the cavities of the drainage as well as the Seal.
