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.
Abstract
Description
Die Erfindung betrifft eine aufrollbare Drainagebahn für die Herstellung von kapillarbrechenden Drainschichten zur Entwässerung von auf ihnen verlegten Belägen, bestehend aus einer aufrollbaren wasserdurchlässigen Abdeckbahn, auf welcher rechtwinklig zur Bahnlängsrichtung verlaufend in parallelem Abstand und somit im Zwischenraum Entwässerungsquerkanäle bildende Streifen aus aufgeschäumtem Kunststoffmaterial haftend befestigt sind, welche mit jeweils einer Anzahl von sich rechtwinklig quer über die Schaumkunststoff-Streifen erstreckenden, in einer Flachseite der Streifen offene Entwässerungslängskanäle bildenden kanalartigen Ausnehmungen versehen sind, welche eine Tiefe haben, die geringer als die Höhe der Schaumkunststoff-Streifen ist.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.
Derartige aufrollbaren Drainagebahnen sind vom Anmelder entwickelt worden (EP- 0 178 382 A1), bei denen durch die Zwischenräume zwischen den quer zur Bahnlängsrichtung auf der Unterseite der Abdeckbahn befestigten Streifen oder Lamellen aus Hart-Schaumkunststoff quer verlaufenden Entwässerungskanäle und durch eine Vielzahl von von der der Abdeckbahn gegenüberliegenden, d.h. der auf dem Untergrund aufzusetzenden Flachseiten aus in die Streifen eingeschnittene, sich nur über einen Teil der Höhe der Schaumkunststoff-Streifen erstreckende Ausnehmungen in Bahnlängsrichtung verlaufende Entwässerungskanäle gebildet werden. Solche - aufgrund der Möglichkeit sie in aufgerolltem Zustand platzsparend zu lagern und zu transportieren und bei der Verlegung einfach von der Rolle auf den Untergrund abzurollen auch als "Rollenbahndrainage" bezeichnete - Drainageelemente werden unter Estriche, Mörtelschichten, lose verlegten Plattenbelägen in Außenbereichen und unter Dachbegrünungen eingesetzt, wobei die der Abdeckbahn gegenüberliegenden Flachseiten der Schaumkunststoff-Streifen oder Lamellen auf der eigentlichen Abdichtung des tragenden Untergrunds, z.B. einem Betonfundament, einer Decken-Tragplatte o.dgl. aufsitzt. Daneben sind zur Herstellung von kapillarbrechenden Drainschichten auch Drainageplatten aus steifen, nicht-aufrollbaren Kunststoffprofilen bekannt, z.B. aus der deutschen Offenlegungsschrift 40 04 901. Solche steifen, nicht-aufrollbaren Drainageplatten haben sich aufgrund ihres geringen Gewichts und der äußerst preisgünstigen Herstellbarkeit bei der Herstellung von kapillarbrechenden Drainschichnen im privatgenutzten Bereich, also auf privaten Balkonen und Terrassen, überaus bewährt. Sie eigenen sich jedoch nicht zur Herstellung von Drainschichten unter stark belasteten Flächen, wie z.B. parkdeckflächen, da die Kunststoff-Profilwände ab einer gewissen Gewichtsbelastung zum Einknicken neigen. Zudem werden die Drainageplatten aus Transportgründen vernünftigerweise immer nur in einer beschränkten Größe hergestellt, so daß die Verlegung eines Balkons oder einer Terrasse üblicher Größe mit solchen Drainageplatten zwar noch in angemessener Zeit möglich ist, das Auslegen einer größeren Fläche, wie z.B. eines Flachdachs oder einer Parkdeckfläche, mit solchen relativ kleinen Drainageplatten jedoch wesentlich mehr Zeit erforderte, als das Ausrollen einer langen ausrollbaren Drainagebahn.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 - Due to the possibility of being rolled up to save and transport space-saving and at the Simply unroll the roll from the roll onto the substrate also known as "roller drainage" - drainage elements are loosely laid under screeds, mortar layers Panel coverings in outdoor areas and under green roofs used, the opposite of the cover sheet Flat sides of the foam plastic strips or Slats on the actual sealing of the load-bearing surface, e.g. a concrete foundation, a ceiling support plate or the like sits on. In addition, for the production of capillary-breaking drain layers also from drainage plates known rigid, non-rollable plastic profiles, e.g. from German Offenlegungsschrift 40 04 901. 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. In addition 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.
Bei der bekannten aufrollbaren Drainagebahn dient das durch die längs- und querverlaufenden Entwässerungskanäle gebildete Kanalsystem sowohl der Abfuhr von eingedrungenem Oberflächenwasser als auch der Belüftung und somit Trocknung der aufgelagerten zu drainierenden Konstruktion. Diese bekannte aufrollbare Drainagebahn hat sich für solche Anwendungsfälle bewährt, bei welchen die auftretenden Belastungen sich in einem gewissen Rahmen halten. Durch das Erfordernis einer einwandfreien Wasserabführung, die natürlich nur in den Bereichen der Abdeckbahn erfolgen kann, welche nicht mit den über die Breite der Abdeckbahn durchlaufenden Schaumkunststoff-Streifen unterklebt sind, müssen die Streifen in einem Abstand auf der Unterseite der Abdeckbahn angeordnet werden, der etwa gleich der Breite der Streifen ist. Da zur wirksamen Entwässerung zusätzlich in die Unterseite der Schaumkunststoff-Streifen die kanalbildenden Ausnehmungen eingeschnitten sind, verringert sich die Aufstandsfläche der Schaumkunststoff-Streifen auf dem Untergrund, d.h. der die Abdichtung belastenden Fläche auf etwa 40 bis 42% der insgesamt zu drainierenden Fläche. Die über die Aufstandsfläche der Schaumkunststoff-Streifen auf den Untergrund zu übertragenden Belastung werden dementsprechend im Bereich der Aufstandsfiächen konzentriert und erhöht. Bei einem Belagsgewicht von durchschnittlich 140 bis 150 kg/m2 und einer zu berücksichtigenden zusätzlichen Verkehrslast von ca. 150 bis 250 kg/m2 wird die Gesamtlast von ca. 300 bis 400 kg/m2 auf nur 40 bis 42% der Gesamtfläche verteilt, was zu einer Verzweieinhalbfachung des Flächendrucks auf die Abdichtung führt die bei den gegenwärtigen Konstruktionen in der Regel aus bituminösen Stoffen besteht.In the known roll-up drainage channel, 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. 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 area stressing the seal, is reduced to approximately 40 to 42% of the total area to be drained. 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. With an average covering weight of 140 to 150 kg / m 2 and an additional traffic load of approx. 150 to 250 kg / m 2 to be taken into account, 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.
Es ist bekannt, daß diese Abdichtungsstoffe thermoplastisch reagieren, und bei steigender Temperatur (unter gedrainten Belägen wird es z.B. unter rotfarbigen Oberflächen auf wärmegedämmten Dachterrassen bis zu 55°C warm) weich werden. Bei Einsatz der bekannten Drainagebahn kann es deshalb auf Flächen, die wesentlich stärkeren Belastungen als Balkone und Terrassen ausgesetzt sind, z.B. bei Parkdeckflächen, die den Belastungen durch die überfahrenden Kraftfahrzeuge ausgesetzt sind, zu Eindrücken kommen, welche bis zu einer Verletzung der Abdichtungsstoffe, z.B. bituminösen Schweißbahnen, führen.It is known that these 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). When using 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.
Der Erfindung liegt die Aufgabe zugrunde, eine mit geringem Zeitaufwand einfach verarbeitbare, kapillarbrechende Rollbahndrainage zu schaffen, welche eine möglichst große entwässerungsfähige Fläche aufweist und dabei gleichzeitig über eine sehr große Auflagefläche verfügt, welche dadurch auch für höhere Belastungen der zu drainierenden Fläche geeignet ist.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.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Schaumkunststoff-Streifen mit der Flachseite an der Abdeckbahn anliegen, in welcher die Entwässerungslängskanäle offen sind, und daß die Abdeckbahn in den zwischen den Entwässerungslängskanälen liegenden Bereichen der Flachseite mit den Schaumkunststoff-Streifen verklebt ist. Bei der Verlegung der so ausgebildeten Drainagebahn liegen also die durchgehenden Flachseiten der Schaumkunststoff-Streifen auf der Unterkonstruktion bzw. deren Abdichtung großflächig auf, während andererseits die abdeckbahnseitige entwässerungsfähige Fläche demgegenüber erheblich vergrößert ist, weil der Durchtritt von Wasser durch die Abdeckbahn nur an den zwischen den die Entwässerungslängskanäle bildenden Ausnehmungen verbleibenden Flachseitenbereichen behindert ist.According to the invention 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. At the laying of the drainage membrane formed in this way is therefore the continuous flat sides of the foam plastic strips on the substructure or its sealing over a large area while, on the other hand, the cover sheet side drainable area, on the other hand, 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.
Die Abdeckbahn ist zweckmäßig etwas breiter als die Länge der Schaumkunststoff-Streifen bemessen, und die Streifen sind an einem Ende bündig zur Längsseite der Abdeckbahn ausgerichtet auf dieser verklebt, so daß die Abdeckbahn an der gegenüberliegenden Längsseite in einem streifenförmigen Bereich über die dortigen Enden der Schaumkunststoff-Streifen übersteht und in diesem Bereich mit der seitlich anschließenden Drainagebahn überlappt werden kann.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.
Zur Vergrößerung der entwässerungsfähigen Fläche ist es zweckmäßig, wenn die von den quer zu den Schaumkunststoff-Streifen verlaufenden Ausnehmungen gebildeten Entwässerungslängskanäle einen sich von ihrem geschlossenen Boden zur unter der Abdeckbahn offenen Flachseite hin in der Breite erweiternden, z.B. einen trapezförmigen, Querschnitt aufweisen.It is to enlarge the drainable area useful if the from the across to the foam plastic strips extending recesses formed longitudinal drainage channels one from her closed floor to the flat side open under the cover sheet in the Widening, e.g. a trapezoidal, cross section exhibit.
Um auch an einem Ende der Drainagebahn eine Überlappungsmöglichkeit mit einer anschließenden Drainagebahn zu schaffen, empfiehlt es sich, die Abdeckbahn an wenigstens einem Ende in einer der Breite wenigstens eines Schaumkunststoff-Streifens entsprechenden Länge nicht mit Schaumkunststoff-Streifen zu versehen und so in diesem Bereich die Überlappung mit der anschließenden Drainagebahn zu ermöglichen.To provide an overlap option at one end of the drainage membrane with a subsequent drainage membrane, it is recommended that 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.
Die Abdeckbahn ist zweckmäßig aus einem Vlies- oder Gittergewebematerial hergestellt, und zwar vorzugsweise einem verrottungsbeständigen Material, obwohl bei bestimmten Anwendungsfällen durchaus auch sich im Laufe der Zeit zersetzende Vliese, Gitterbahnen oder Gewebe Verwendung finden können. Bei aushärtenden Estrichbelägen,genügt es beispielsweise, wenn das Material der Abdeckbahn solange stabil ist, bis die darauf aufgebrachte Estrichschicht ausgehärtet und somit eigenstabil ist.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.
Auf der der Abdeckbahn gegenüberliegenden Flachseite der Schaumkunststoff-Streifen kann zusätzlich eine wärme- und/oder schalldämmende Schicht haftend aufgebracht sein, welche die Abdichtung zusätzlich auch vor druckbedingten Beeinträchtigungen schützt und die auf die Abdichtung einwirkenden Schubkräfte des darauf liegenden Belages, der sich ja bei wechselnden Temperaturen ausdehnen oder zusammenziehen kann, vermindert.On the flat side of the 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.
Von Vorteil ist auch eine Ausgestaltung derart, daß wenigstens einer der beiden am vorderen bzw. rückwärtigen Ende der Abdeckbahn vorgesehenen Schaumkunststoff-Streifen an seiner freien Längsseite eine zur Längsseite und der der Abdeckbahn gegenüberliegenden Flachseite offene seitliche Ausnehmung aufweist, deren rechtwinklig zu den Flachseiten der Schaumkunststoff-Streifen gemessene Tiefe größer als die Materialstärke der zwischen der abdeckbahnabgewandten Flachseite und dem Boden der die Entwässerungslängskanäle bildenden Ausnehmungen ist. Dadurch schneiden diese seitlichen Ausnehmungen in den Bereich der die Entwässerungslängskanäle bildenden Ausnehmungen und bilden so auch bei Verlegung aufeinanderfolgender Drainagebahnen derart, daß die endständigen Schaumkunststoff-Streifen aneinander liegen, Durchtrittsöffnungen zu einem von den seitlichen Ausnehmungen gebildeten Entwässerungsquerkanal.An embodiment such that at least one of the two at the front or rear end provided on the cover sheet foam plastic strips its free long side one to the long side and that of Cover sheet opposite flat side open side Has recess whose perpendicular to the flat sides the foam plastic strip measured depth greater than the thickness of the material between the facing away from the cover sheet Flat side and the bottom of the longitudinal drainage channels forming recesses. This will cut these side Recesses in the area of the longitudinal drainage channels forming recesses and thus also form Laying successive drainage channels in such a way that the terminal foam plastic strips together lie, passage openings to one of the side Recesses formed drain cross channel.
Dabei hat es sich als zweckmäßig erwiesen, wenn die parallel zu den Längsseiten des jeweiligen Schaumkunststoff-Streifens gemessene Breite der seitlichen Ausnehmung jeweils etwa gleich der halber Breite des die Entwässerungsquerkanäle bildenden Zwischenraums zwischen zwei in der Drainagebahn aufeinanderfolgenden Schaumkunststoff-Streifen ist.It has proven to be useful if the parallel to the long sides of the respective foam plastic strip measured width of the lateral recess in each case about equal to half the width of the drainage cross canals forming space between two in the Drainage membrane successive foam plastic strips is.
Die Schaumkunststoff-Streifen können jeweils über ihre gesamte Länge einstückige Streifen sein, oder sie können aus wenigstens zwei kürzeren, fluchtend an dem Stoßstellen aneinanderliegend mit der Abdeckbahn verklebten Streifenabschnitten zusammengesetzt sein.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.
Das Verhältnis der Breite der die Entwässerungsquerkanäle bildenden Zwischenräume zwischen benachbarten Schaumkunststoff-Streifen wird zweckmäßig im Bereich zwischen zwei 2 : 8 und 1 : 9 gewählt. Hierdurch wird eine vergleichsweise große Abstützfläche der Drainagebahn auf dem Untergrund erhalten, ohne daß die Möglichkeit des Aufrollens der Drainagebahn zum Zweck der Lagerung und des Transports beeinträchtigt würde.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.

durchgetretenes Wasser abfließen zu lassen.In Figures 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

Die in Figur 2 veranschaulichte Anwendung der Drainagebahn
10 unterscheidet sich von der zuvor beschriebenen Anwendung
dadurch, daß der die begehbare Fläche bildende Belag von
direkt auf der Drainagebahn 10 lose aufgelegten Platten 20
gebildet wird.The use of the drainage membrane illustrated in FIG. 2
10 differs from the previously described application
in that the covering of
Loosely placed
Die Drainagebahn 10 selbst wird von einer Abdeckbahn 13 aus
einem - vorzugsweise - verrottungsbeständigen biegeweichen
und wasserdurchlässigen Material, beispielsweise einem
Vliesmaterial aus Kunststoffasern, gebildet, auf deren Unterseite
in gleichmäßigen Abständen Schaumkunststoff-Streifen
11 aus Hartschaum, z.B. aufgeschäumtem Polystyrol, in
Querrichtung in geringem Abstand aufgeklebt sind. Die
Schaumkunststoff-Streifen 11 sind an ihrer der Abdeckbahn
13 zugewandten Flachseite mit einer Vielzahl von in Längsrichtung
der Abdeckbahn verlaufenden Ausnehmungen 12 versehen,
welche über die gesamte Breite der Streifen 11 durchlaufen
und auf diese Weise Entwässerungslängskanäle bilden.
Hierzu rechtwinklig verlaufende Entwässerungsquerkanäle
werden durch den Zwischenraum 14 zwischen aufeinanderfolgenden
Schaumkunststoff-Streifen 11 gebildet, so daß unterhalb
der Abdeckbahn 13 also ein Kanalsystem zur Abfuhr des
über die wasserdurchlässige Abdeckbahn 13 hindurchtretendes
Wasser entsteht. An einer Längsseite (Fig. 5 und 6) und einem
Ende (Fig. 4) steht ein streifenartiger Abschnitt der
Abdeckbahn 13 über die Schaumkunststoff-Streifen 11 vor.
Diese streifenförmig überstehenden Bereiche 15 der Abdeckbahn
dienen zur Überlappung mit bei der Verlegung seitlich
oder stirnseitig anschließenden Drainagebahnen 10.The
Die erfindungsgemäße Drainagebahn 10 kann in sehr langen
aufrollbaren Bahnen hergestellt werden. Flächen bis zu 50
m2 oder mehr können so auf einer einzigen Rolle sehr rationell
auf großflächigen Parkdecks, begrünten Tiefgaragendecks
oder auf begrünten Dächern in kürzester Zeit ausgelegt
werden. Die am vorderen und rückwärtigen Ende vorgesehenen
Schaumkunststoff-Streifen 11 können in der in Figur 4
gezeigten Weise an ihren freien Längsseiten seitliche Ausnehmungen
16 aufweisen, welche nach unten und zur Längsseite
hin offen sind. Aneinanderstoßende Streifen 11 der
Enden aufeinanderfolgender Drainagebahnen 10 bilden im Bereich
der seitlichen Ausnehmungen 16 Entwässerungsquerkanäle,
in welche das über die die Entwässerungslängskanäle
bildenden Ausnehmungen 12 zuströmende Wasser seitlich
abgeführt werden kann. Auf den großflächigen Unterseiten
der Schaumkunststoff-Streifen 11 kann gegebenenfalls
noch eine - nur in Figur 3 angedeutete - wärme- und/oder
schalldämmende Schicht 17 aufkaschiert sein, die beispielsweise
ebenfalls von einem Schaumkunststoff gebildet
wird, der jedoch welcher als das Hartschaummaterial der
Streifen 11 eingestellt sein kann.The
Aus der vorstehenden Beschreibung wird klar, daß die erfindungsgemäße
Drainagebahn 10 eine Reihe von Vorteilen gegenüber
bekannten Drainagekonstruktionen erzielt. From the above description it is clear that the
Auf der Drainagebahn verlegte Beläge werden kapillarbrechend gedraint, so daß z.B. bei Belagsaufbauten aus Fliesen mit Zementestrich im Außenbereich Frostschäden und Ausblühungen mit Sicherheit ausgeschlossen werden.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.
Die wasserdurchlässige Fläche der Abdeckbahn zwischen den
Ausnehmungen in der abdeckbahnzugewandten Flachseite der
Schaumkunststoff-Streifen 11 wird besonders groß, nämlich
in der Praxis um 20 bis 30% größer als bei bisher bekannten
Produkten, und gewährleistet so eine optimale Wasserableitung
aus darüber verlegten Belagschichten.The permeable surface of the cover sheet between the
Recesses in the flat side of the cover sheet facing the
Die Aufstandsfläche der erfindungsgemäßen Drainagebahn sind so groß, daß es gegenüber voll aufliegenden (nicht gedrainten Belägen) nur zu einer minimalen und deshalb vernachlässigbaren Druckerhöhung auf die darunterliegende Abdichtung kommt. Die Gefahr des Eindrückens der Abdichtung unter Last ist deshalb auch auf stark belasteten Flächen, z.B. Parkdecks, nicht mehr gegeben.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.
Die erforderlichenfalls erfolgende Aufkaschierung einer weicheren Schalldämmschicht auf die Unterseite der Schaumkunststoff-Streifen 11 schont die Abdichtung und schützt sie vor gefährlichen Schubspannungen, wobei gleichzeitig eine wesentliche Verbesserung des Trittschallschutzes erreicht wird.The necessary lamination of a softer soundproofing layer on the underside of the foam plastic strips 11 protects the seal and protects them from dangerous shear stresses, being simultaneous achieved a significant improvement in impact sound insulation becomes.
Bei losen Belagsaufbauten ohne Zementestrich verhindert die wasserdurchlässige Abdeckschicht mit Filterwirkung sowohl die Verschmutzung der Hohlräume der Drainung wie auch der Abdichtung.In the case of loose covering structures without cement screed, the water-permeable cover layer with filter effect both the pollution of the cavities of the drainage as well as the Seal.
