Definitions

  • the invention relates to a roll-up drainage sheet for the production of capillary-breaking drain layers for the drainage of coverings laid on them, consisting of a roll-up water-permeable cover sheet, on which strips of foamed plastic material are attached, perpendicular to the longitudinal direction of the sheet, at a parallel distance and thus in the space forming transverse drainage channels.
  • a roll-up drainage sheet for the production of capillary-breaking drain layers for the drainage of coverings laid on them, consisting of a roll-up water-permeable cover sheet, on which strips of foamed plastic material are attached, perpendicular to the longitudinal direction of the sheet, at a parallel distance and thus in the space forming transverse drainage channels.
  • Such roll-up drainage sheets have been developed by the applicant (EP-0 178 382 A1), in which drainage channels run transversely through the spaces between the strips or lamellae made of rigid foam plastic and fastened transversely to the longitudinal direction of the sheet on the underside of the cover sheet and are formed by a multiplicity of drainage channels running in the longitudinal direction of the web from the flat sides opposite the covering web, ie the flat sides to be placed on the substrate, into the strips, which extend only over part of the height of the foam plastic strips.
  • roller conveyor drainage Such - due to the possibility of storing and transporting them in a rolled-up state to save space and transporting them and simply unrolling them from the roll onto the subsurface, also known as "roller conveyor drainage” - drainage elements are used under screeds, mortar layers, loosely laid slab coverings outdoors and under green roofs ,
  • the channel system formed by the longitudinal and transverse drainage channels serves both the removal of penetrated surface water and the ventilation and thus drying of the superimposed structure to be drained.
  • the well-known 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 be done in the areas of the cover sheet that 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 is about is equal to the width of the stripes. Since the channel-forming recesses are additionally cut into the underside of the foam plastic strips for effective drainage, the contact area of the foam plastic strips on the subsurface, ie the surface that loads the seal, is reduced to approximately 40 to 42% of the total area to be drained.
  • the transferring load is accordingly concentrated and increased in the area of the contact patch.
  • an average covering weight of 140 to 150 kg / m2 and an additional traffic load of approx. 150 to 250 kg / m2 to be taken into account the total load of approx. 300 to 400 kg / m2 is distributed over only 40 to 42% of the total area, which means a two-and-a-half-fold increase in the surface pressure on the seal, which in the current designs usually consists of bituminous materials.
  • the invention has for its object to provide a capillary-breaking roller drainage that is easy to process in a short amount of time, which has the largest possible drainable surface and at the same time has a very large contact surface, which is therefore also suitable for higher loads on the surface to be drained.
  • this object is achieved in that the foam plastic strips rest with the flat side on the cover sheet in which the drainage channels are open, and in that the cover sheet is glued to the foam plastic strips in the areas of the flat side lying between the drainage channels.
  • the cover sheet is expediently dimensioned somewhat wider than the length of the foam plastic strips, and the strips are glued to one end flush with the longitudinal side of the cover sheet, so that the cover sheet on the opposite long side in a strip-shaped area over the ends of the foam plastic there -Strip protrudes and can be overlapped in this area with the laterally connected drainage membrane.
  • the drainage channels formed by the recesses running transversely to the foam plastic strips expand in width from their closed bottom to the flat side open under the cover sheet, e.g. have a trapezoidal cross-section.
  • the cover sheet is expediently made of a nonwoven or lattice fabric material, and preferably a rotting-resistant material, although in certain applications it also decomposes over time Nonwovens, grid webs or fabrics can be used.
  • a rotting-resistant material although in certain applications it also decomposes over time
  • Nonwovens, grid webs or fabrics can be used.
  • a heat and / or soundproofing layer can additionally be applied, which additionally protects the seal against pressure-related impairments and the shear forces acting on the seal of the covering lying thereon, which changes with changing Can expand or contract temperatures, reduced.
  • At least one of the two foam plastic strips provided at the front or rear end of the cover sheet has on its free long side a lateral recess open to the long side and the flat side opposite the cover sheet, the right-angled to the flat sides of the foam plastic Strip depth measured is greater than the material thickness of the flat side facing away from the cover sheet and the bottom of the recesses forming the drainage channels.
  • these lateral recesses cut into the region of the recesses forming the longitudinal drainage channels and thus also form passage openings to a transverse drainage channel formed by the lateral recesses when laying successive drainage channels in such a way that the terminal foam plastic strips lie against one another.
  • the width of the lateral recess measured parallel to the long sides of the respective foam plastic strip is approximately equal to half the width of the space between the cross-drainage channels between two in the Drainage sheet is successive foam plastic strips.
  • the foam plastic strips can each be one-piece strips over their entire length, or they can be composed of at least two shorter strip sections which are aligned with one another at the abutting points and are bonded to the cover sheet.
  • the ratio of the width of the spaces between adjacent foam plastic strips forming the cross-drainage channels is expediently chosen in the range between two 2: 8 and 1: 9.
  • 1 and 2 show two different possibilities for the construction of outdoor floor constructions, for example balconies, terraces, parking decks and other areas to be drained, which using the drainage membrane 10 according to the invention described in more detail below in connection with FIGS. 3 to 6 break capillary be drained.
  • 1 illustrates the use of the drainage membrane 10 for the drainage of a covering of tiles 19 laid on a cement screed layer 18.
  • the cement screed 18 is applied directly to the drainage membrane 10, which in turn rests on a bituminous sealing membrane 21, which counteracts the foundation 22 Seals water.
  • the foundation 22 or a separate layer applied to it have a slight slope at the top in order to allow water that has passed through to the sealing membrane to flow away.
  • the application of the drainage membrane 10 illustrated in FIG. 2 differs from the previously described application in that the covering forming the walkable surface is formed by plates 20 which are loosely placed directly on the drainage membrane 10.
  • the drainage sheet 10 itself is formed by a cover sheet 13 made of a - preferably - rot-resistant, flexible and water-permeable material, for example a non-woven material made of plastic fibers, on the underside of which foam plastic strips 11 made of rigid foam, e.g. foamed polystyrene, glued in the transverse direction at a short distance.
  • the foam plastic strips 11 are provided on their flat side facing the cover sheet 13 with a plurality of recesses 12 running in the longitudinal direction of the cover sheet, which pass through 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 m2 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 16 transverse drainage channels in the area of the lateral recesses, into which the water flowing in via the recesses 12 forming the longitudinal drainage channels can be discharged laterally.
  • a heat and / or sound-insulating layer 17, which is only indicated in FIG. 3, can optionally also be laminated on, which is also formed, for example, by a foam plastic, which, however, is softer than the rigid foam material of the strips 11 may be.
  • Coverings laid on the drainage membrane are drained in a capillary-breaking manner, so that e.g. frost damage and efflorescence can be excluded with certainty in the case of covering structures made of tiles with cement screed.
  • the water-permeable surface of the cover sheet between the recesses in the flat side of the foam plastic strips 11 facing the cover sheet becomes particularly large, namely in practice by 20 to 30% larger than in previously known products, and thus ensures optimal water drainage from covering layers laid over it.
  • the contact area of the drainage membrane according to the invention is so large that there is only a minimal and therefore negligible increase in pressure on the underlying seal compared to fully lying (not drained coverings).
  • the risk of the seal being pressed in under load is therefore also on heavily loaded surfaces, e.g. Parking decks, no longer available.
  • the water-permeable cover layer with filter effect prevents both the contamination of the drainage cavities and the seal.
