Abstract

For the production of surface drainage for drainage of screeds, mortar layers and other coverings on it, plastic profile drainage membrane made of profiled rigid plastic, which, thanks to U-shaped profiles that are alternately spaced apart in parallel to the top and bottom, form two planes creating horizontal surfaces, so that external appearance Open parallel drainage channels (1) open at the top, which are delimited by the web walls (2) of the spacer webs (3) forming the inner drainage channels (7) which are open at the bottom. DOLLAR A A water-permeable cover sheet (5) is glued to the upper horizontal surfaces (4), which covers the outer drainage channels (1) which are open at the top, with drainage openings (3) forming the drainage channels (7) which are open at the bottom from above (6) are incorporated, which connect the parallel drainage channels (1; 7).

Description

The invention relates to a drainage membrane for manufacture from surface drainage to drainage on top of it Screeds, mortar layers and other coverings.

Such a drainage membrane made of plastic is from DE 86 05 696 U1 known, which occur between upwards the parallel groups of rib-like spacers for Top forms open drainage channels through one on water permeable applied to the end faces of the profiles top cover are completed so that the when laying a tile covering on the top Do not put mortar or adhesive to be applied into the channels can penetrate and over the spaces between the slab and water seeping through the adhesive or mortar  can be discharged in the longitudinal direction of the channels. This well-known drainage membrane should be next to one opposite the Known prior art also improved load capacity the arrangement of an additional waterproof underlay Avoid on the balcony or terrace bare brick. Out for this reason the well-known drainage membrane is also overall fully waterproof, so that the liquid to be drained exclusively via the drainage channels open at the top can be removed. Dement speaking stands for the removal of - z. B. with strong Downpours and thunderstorms - gushing water as the discharge cross section only the sum of the cross sections of the drainage channels open to the top are available.

DE 35 13 611 A1 is a drainage plate made of art known substance, which only in its underside Draina has channels that are predominantly formed by longitudinal channels be between the parallel, to the underside spacing bars. The spacers are supposed to have additional transverse lamella cuts, which, however, have no additional drainage cross-sections provide, but only a better up position of the spacers on the surface. So that the Be on the drainage mat to be applied there was water flowing into the drainage channels can get, this is punched through the distance Provide webs, which thus interrupt the spacers and thus a system of connecting the longitudinal channels Form cross channels. On the waterproof Abdich tion facing surface of the drainage plate are kei There are no additional drainage channels provided. The one for the quick and complete drainage of water available standing drain cross-section is with this known Drai nage plate from the passage cross section of the mentioned Die cuts are given and therefore relatively low.

In contrast, the invention is based on the object to create the largest possible drainable area and so a quick removal of the penetrating surfaces to ensure water, while at the same time a leg the intended area on the surface to be sealed separate sealing by the on the drainage membrane lying weight should be avoided.

Starting from a drainage membrane of the type mentioned at the beginning This object is achieved according to the invention by the features of claim 1.

The following advantages are achieved with the invention:

• 1. The drainable area is larger than average
• 2. The contact surface of the drainage sheet is so large that pressing into the seals is not possible.
• 3. Leachate stuck on the seal has no capillary contact to the overlying mortar or screed layers.

An embodiment is shown and described.

The art of sealing balconies and patios fabric profile drainage channels designed so that the drain channels point in the main drainage direction. The cover The approaches to the overlaps of the individual drainage sheets adjacent drainage channels.

A screed is laid on the plastic profile drainage membrane Load distribution layer in which a reinforcement is embedded becomes. Suitable tiles or slabs are then placed in the thin bed or "fresh in fresh". After the mortar has hardened the grouting is carried out.

The surface water penetrating over the joints of the covering seeps through the screed into the cavities of the plastic profile Drainage membrane and becomes the drainage system in their canal system (e.g. gutter).

The plastic profile drainage membrane consists of outer drain channels ( 1 ) and spacers ( 3 ), the cavity underneath of which forms the inner drain channels ( 7 ). In the spacer webs, drainage openings are worked in from above, transversely to their course, so that leachate in the screed through these drainage openings ( 6 ) can also reach the inner drainage channels ( 7 ), but can also drain across the drainage channels.

These elaborations also have the purpose of improving the adaptability of the plastic profile drainage membrane to the subsurface. On the spacer webs (3) the water-permeable cover sheet (5) is glued.

It keeps the cavities of the outer drain channels ( 1 ) free of mortar or screed, so that unhindered drainage can take place.

So that no mortar gets into the drainage channels or onto the seal in the attachment area, the water-permeable cover sheet overlaps at least on one side, or the plastic profile of the plastic profile drainage sheet is overlaid, for example, as shown in Fig. 4.
