Definitions
- the invention relates to a drainage membrane for the production of surface drains for dewatering the layers lying thereon, such as screeds, mortar or adhesive layers and other coverings, such as floor slabs or ceramic tiles or for the rear ventilation of exterior wall cladding of buildings, consisting of an inherently rigid plastic film, which is profiled by strip-shaped sections running parallel at a close spacing and successively folded over in the opposite sense to the previous strip-shaped section in such a way that open-ended channels alternate on the underside to the support plate and on the top side to the layer lying thereon, with the upper side facing the layer lying thereon a liquid- and gas-permeable cover sheet is adhesively applied, and at least in the strip-shaped sections forming the lateral boundaries of the channels, a number of spaced-apart continuous openings Openings are provided which produce a liquid and gas permeable connection of the channels open to the top with the channels of the profile sheet open to the bottom.
- the known drainage sheets (e.g. DE-A-40 04 901) have also proven their worth here as long as the covering layer to be drained, e.g. a screed layer and - if necessary - additional slab coverings are not too heavy or do not have too much additional weight on the layer to be drained, i.e. the floor area to be drained is not used by vehicles, especially trucks.
- the covering layer to be drained e.g. a screed layer and - if necessary - additional slab coverings are not too heavy or do not have too much additional weight on the layer to be drained, i.e. the floor area to be drained is not used by vehicles, especially trucks.
- the invention has for its object the known
- this object is achieved according to the invention in that the sections forming the lateral boundaries in the regions lying between the through openings are provided with profilings which increase the resistance to deformation under weight load.
- the profiles are formed by parallel ribs which run essentially vertically over the entire height of the strip-shaped sections and which therefore provide a substantial stiffening of these strip-shaped sections with respect to FIG bring vertical loads acting in the vertical direction.
- the ribs are preferably formed by wave-shaped deformation in the horizontal cross section of the strip-shaped sections forming the lateral boundaries of the channels, i.e. the vertical ribs are produced only by deforming the strip-shaped sections. The formation of the ribs therefore does not require any additional plastic material.
- the ribs can also be formed by zigzag or trapezoidal deformations of the strip-shaped sections forming the lateral boundaries of the channels. Such sharp-edged ribs can further increase the load-bearing capacity of the drainage membrane.
- the liquid and gas permeable cover sheet can either consist of a plastic fleece material which is impermeable to mortar or tile adhesive. Screed, mortar or adhesive applied to the drainage membrane arranged on a substrate will not penetrate through the fleece layer and an optimal drainage cross section of the drainage membrane will be obtained.
- the liquid- and gas-permeable cover sheet can also be formed by a mesh fabric sheet, for example a glass mesh fabric, which is permeable to screed, adhesive or mortar that has not set or hardened. Screed, mortar or adhesive applied to such a drainage membrane can then pass through the mesh fabric into the channels open at the top and harden or set. The load-bearing capacity of the drainage membrane is then additionally increased by this hardened material, a loss of drainage cross section in the drainage membrane being accepted.
- a mesh fabric sheet for example a glass mesh fabric, which is permeable to screed, adhesive or mortar that has not set or hardened. Screed, mortar or adhesive applied to such a drainage membrane can then pass through the mesh fabric into the channels open at the top and harden or set. The load-bearing capacity of the drainage membrane is then additionally increased by this hardened material, a loss of drainage cross section in the drainage membrane being accepted.
- the spaced-apart through openings are formed by spaced-apart perpendicular to the channels that form the slit-shaped openings that pass through the lateral boundaries and the bottom of the top-opening channels, it can be advantageous if at least in the area of some of the laterally spaced apart extending slot-shaped openings which are each connected to the underside open channels of the upper side strip-shaped sections by transverse webs. These webs then run immediately below the cover sheet and form spacer webs between the strip-shaped sections of the profile sheet which close off the channels on the underside on the upper side, as a result of which the ribs and the cover sheet adhering to them are tensioned in the installed state.
- the drainage membrane can also be designed in such a way that the channels closed at the bottom in their areas lying between the continuous openings have a number of continuous channels from one another have spaced bottom slot openings, it can be advantageous if these bottom slot openings continue into the strip-shaped sections laterally delimiting the channels and then extend over part of the height of these sections.
- Fig. 1 is a perspective view of a
- Fig. 2 is a view of the front of the
- FIG. 3 shows a perspective view corresponding to FIG. 1 of a somewhat modified exemplary embodiment of a drainage membrane according to the invention.
- FIG. 4 is a vertical sectional view through a section of an outer wall consisting of ceramic plates and ventilated by means of the inventive drainage membrane.
- the drainage sheet according to the invention designated in its entirety by 10 in FIGS. 1 and 2, consists of a profile sheet 12 made from an originally flat, thin, rigid plastic film, on the top of which then, after its profiling, a - in FIG Profile sheet 12 shown - liquid and gas permeable cover 14 made of a non-woven plastic material or a glass mesh fabric is adhered.
- the profiled sheet 12 has strip-shaped sections (16a; 18; 16b) which run parallel to one another at a close spacing and are successively angled in the opposite sense to the preceding strip-shaped section and which alternately form open channels 20 and 22 on the top and bottom.
- the channels 20 and 22 are connected to one another by slot-like openings (24a and 24b) which extend at a lateral distance from one another in the web direction and which pass through the lateral boundaries and the bottom of the channels (18; 16b) which open on the top side, so that from the Upper side of water flowing into the channels 20 can also pass through the openings 24a, 24b into the channels 22 and thus overall a discharge cross-section is created via the channels 20, 22, which is narrowed only by the material thickness of the thin strip-shaped sections 18 . Almost the complete space between a screed or covering layer supported by the drainage membrane according to the invention and the support plate on the underside is available as a drainage cross section.
- the strip-shaped sections 18 laterally delimiting the channels 20 and 22 in each case are stiffened by vertical parallel ribs running essentially over their entire height in that these strip-shaped sections 18 are still undulating during profiling have been deformed.
- the sections 18 are substantially stiffened against deformation as a result of resting weight loads, ie the drainage sheet 10 can also be used for the drainage of floor covering surfaces in which, in addition to the weight loading by the floor covering itself, additional weight loads are applied. loads, e.g. from loaded trucks etc., must be expected.
- laterally spaced slot-shaped openings 24a and 24b are provided, of which the openings 24a have a relatively small width.
- a wider slot-shaped opening 24b is then provided in each case.
- the adjacent upper strip-shaped sections 16a of the profile sheet 12 are connected in the area of these wider slot-shaped openings 24b by stabilizing webs 26, which ensure that the channels open on the top side do not become exposed to the weight of the screed when the screed, which is still plastic, is applied to the top of the covering sheet 14 can deform in the sense of narrowing the channel 12.
- the covering sheet 14 adhered to the top of the strip-shaped sections 16a is therefore not arched into the channels 20 by the weight of the still screed, so that a reduction in the outflow cross-section of these channels is avoided by such a bulge.
- the possibility of breakage with certain materials, for example glass mesh fabric, with the consequence of damage to the cover sheet in the rolled-up transport or storage state due to buckling and thus the possibility of screed penetrating into the channels 20 is thus reliably excluded.
- FIG. 3 shows a drainage web 10 ′ modified compared to the drainage web 10 described above, which differs from the previously described drainage web only in that strip-shaped sections 16b forming the bottom of the channels 20 closed at the bottom in the region between the slot-like opening channels openings 24a, 24b additional through slot openings 28 are provided, which - over part of the height - Continue into the strip-shaped sections 18 forming the lateral boundary walls of the channels 20.
- the channels 20 or 22 laterally delimiting strip-shaped sections 18 of the profiled sheet 12 can also be arranged at a slight incline, so that the channels 22 'closed at the top have a trapezoidal cross section, which increases the load-bearing capacity of the drainage sheet with respect to weight load .
- the ribs formed by this deformation can also be formed by deformations which are zigzag or trapezoidal in cross section, which also increases the load capacity can.
- the cover 14 adhered to the top of the drainage sheet 10 or 10 ′ can consist not only of a non-woven plastic material, but also of a wider-meshed glass mesh fabric, through which fresh, even more elegant screed or mortar or tile adhesive can pass through and then fill the channels 20 open at the top and harden there.
- FIG. 4 shows an application of the drainage membrane 10 according to the invention for the rear ventilation of facade cladding, e.g.
- a facade cladding made of ceramic plates 30 illustrates how it is often provided - in particular also on the ground floor of business or office buildings.
- the drainage membrane 10 is in shape with the channels 20, 22 running vertically on the outside of an outer wall insulating layer 32 used for thermal insulation attached by mineral wool or plastic foam panels to the outer wall 34 of a building.
- the usual plate anchors 36 are used for this fastening, the shafts 38 of which are passed through the drainage membrane 10 and the insulating layer 32 and anchored in the outer wall 34 of the building.
- a plate dowel 36 is shown.
- the plate-like or disk-like flat heads 40 of the plate dowels 36 provided at the outer end of the shaft 38 rest on the upper side of the drainage membrane 10 facing away from the outer wall.
- the ceramic plates 30 are then held on the drainage track with a plastic-bound mortar or adhesive layer 42, which also embeds the heads 40 of the plate dowels 36, the cover 14, which here expediently consists of a high-strength, wide-meshed glass mesh fabric, providing a highly resilient connection between the ceramic plates 30 and the drainage membrane 10 ensures.
