Abstract

Flat sheet sealing system (1) for the construction industry comprises at least two thermoplastic facing sheets (2,3) sepd. by and connected to each other by distance pieces (4). A process for mfg. the sealing system (1) involves (i) extrusion and calendering a first sheet (2) with integral projections, (ii) extrusion of a second smooth faced sheet (3), (iii) bringing together both sheets (2,3), and (iv) connecting sheets (2,3) by welding the projecting distance pieces (4) to the smooth sheet (3) to form a twin-walled structure. The distance pieces (4) form an integral part of the first sheet (2) and have a columnar or truncated conical profile. Distance pieces (4) form an integral part of the first sheet (2) and are welded to the second sheet using welding pips at the free ends. Welding is achieved by (i) ultrasonics, (ii) heated wedge radiation or (iii) infra-red. Anchoring pips may be provided on the rear face of the second sheet (3). USE/ADVANTAGE - The system is used in construction esp. in reservoir or channel-shaped structures. The sealing system is reliable, simple to mfr., can be tested after installation and is repairable. The twin skin construction allows simple testing using sampling tubes or vacuum application.

Description

Die Erfindung bezieht sich auf ein flächiges Bauwerkabdich­ tungssystem mit mindestens zwei Platten aus thermoplastischem Kunststoff. Die Platten sind gemäß der Erfindung über Ab­ standhalter miteinander verbunden. Das System dient vorzugs­ weise zum Auskleiden von becken- oder wannenartigen Bauwerken. Die Erfindung bezieht sich weiterhin auf ein Verfahren zur Herstellung solcher flächiger Bauwerkabdichtsysteme in Dop­ pelwandbauform.The invention relates to a two-dimensional structure system with at least two sheets of thermoplastic Plastic. The plates are according to the invention via Ab stand holders connected to each other. The system is preferred wise for lining basin-like or tub-like structures. The invention further relates to a method for Production of such flat building sealing systems in Dop pelwand design.

Abdichtsysteme oder Abdeckplatten, insbesondere für becken- und wannenartige Bauteile, sind bekannt. Sie bestehen in der Regel aus Kunststoffplatten, die auf einem Schutzestrich im Bauwerk verlegt werden. Von besonderer Wichtigkeit sind derartige Abdichtungen bei Bauwerken, in denen mit Chemikalien hantiert oder in denen diese gelagert werden. Es bedarf keiner sonderlichen Erwähnung, daß von solchen Abdichtungen eine zuverlässige Dichtwirkung gefordert wird, die auch nachprüfbar sein soll. Im Falle von erkannten Undichtigkeiten soll ein derartiges System auch reparierbar sein. Sealing systems or cover plates, especially for basin and trough-like components are known. They consist in the Usually made of plastic sheets that are on a protective screed in the Building to be relocated. Are of particular importance such seals in buildings in which chemicals handles or in which they are stored. No one is needed Special mention that such seals reliable sealing effect is required, which is also verifiable should be. In the case of detected leaks, a such a system can also be repaired.  

Diese Forderungen erfüllt das flächige Bauwerkabdichtsystem gemäß der Erfindung mit seiner doppelschaligen Ausbildung, bei dem die beiden Platten über vorzugsweise diskrete Abstandhal­ ter miteinander verbunden sind. Gemäß der Erfindung sind die Abstandhalter an einer ersten Platte einstückig vorgesehen und des weiteren vorzugsweise säulen- oder kegelstumpfförmig ausgebildet. Erfindungsgemäß ist hierbei vorgesehen, daß die einstückig an der ersten Platte vorgesehenen Abstandhalter mit der anderen oder zweiten Platte verschweißt sind. Auf diese Weise ergibt sich trotz der eigentlich nur vorhandenen punk­ tuellen Verbindung über die diskret angeordneten Abstandhalter eine zuverlässig feste Verbindung der beiden Platten. Es entsteht hierdurch ein doppelschaliges Bauelement mit einem nur durch die diskret angeordneten Abstandhalter unterbro­ chenen Innenraum. Das so erhaltene erfindungsgemäße Abdich­ tungssystem kann mit großem Vorteil im Bauwerk, beispielsweise einem Becken, ohne gesonderten Schutzestrich verlegt werden. Die beschriebene feste Verbindung der beiden Platten mitein­ ander verhindert eine signifikant unterschiedliche Wärmedeh­ nung der beiden Platten bei auftretenden Temperaturwechseln.The flat building sealing system fulfills these requirements according to the invention with its double-shell training, at which the two plates preferably over discrete distances ter are interconnected. According to the invention Spacers provided in one piece on a first plate and further preferably columnar or frustoconical educated. According to the invention it is provided that the spacers provided in one piece on the first plate the other or second plate are welded. To this Way arises despite the only existing punk current connection via the discretely arranged spacers a reliable firm connection of the two plates. It this creates a double-shell component with a only through the discreetly arranged spacers underneath interior. The Abdich according to the invention thus obtained system can be of great advantage in the building, for example a basin, without a separate protective screed. The described firm connection of the two plates other prevents significantly different heat expansion the two plates when the temperature changes.

Es liegt weiterhin im Rahmen der Erfindung, wenn die Abstand­ halter mit der zweiten Platte mittels Ultraschall verschweißt sind. Mit einer entsprechenden Ultraschallvorrichtung läßt sich die Verschweißung mit großer Genauigkeit durchführen. Es liegt jedoch auch im Rahmen der Erfindung, wenn die Abstand­ halter mit der zweiten Platte unter Zuhilfenahme von direktem Wärmeeinfluß, insbesondere mittels Heizkeilstrahlung oder Infrarotstrahlung, verschweißt sind.It is also within the scope of the invention if the distance holder is ultrasonically welded to the second plate are. With an appropriate ultrasound device the welding is carried out with great accuracy. It However, it is also within the scope of the invention if the distance holder with the second plate with the help of direct Influence of heat, in particular by means of hot wedge radiation or Infrared radiation, are welded.

Eine besonders gute Verankerung des erfindungsgemäßen, doppelschaligen Bauwerkabdichtungssystems ergibt sich dann, wenn die zweite Platte auf der den Abstandhaltern gegenüber­ liegenden Seite mit Verankerungsnoppen versehen ist. Diese Noppen greifen in den Beton bzw. Estrich des Bauwerkes ein und sichern eine feste Verbindung des erfindungsgemäßen Systems im Bauwerk. A particularly good anchoring of the inventive double-shell building sealing system then results if the second plate is on the opposite of the spacers lying side is provided with anchoring knobs. These Nubs engage in the concrete or screed of the building and ensure a firm connection of the system according to the invention in Building.  

Wie eingangs erwähnt, bezieht sich die Erfindung gleichermaßen auf ein Verfahren zur Herstellung solcher flächiger Bauwerk­ abdichtungssysteme. Das erfindungsgemäße Verfahren zeichnet sich dadurch aus, daß im Wege des Extrudierens und Kalandrie­ rens eine erste Platte mit Ansätzen sowie eine zweite, im wesentlichen glatte Platte hergestellt werden, daß beide Platten zusammengeführt werden und daß die Ansätze mit der glatten Platte zur Bildung eines doppelwandigen Gebildes miteinander verschweißt werden.As mentioned at the beginning, the invention relates equally on a method for producing such a flat structure sealing systems. The method according to the invention draws is characterized in that by way of extrusion and calendering rens a first plate with approaches and a second, in essentially smooth plate that both are made Plates are merged and that the approaches with the smooth plate to form a double-walled structure are welded together.

Das erfindungsgemäße Verfahren zeichnet sich durch relative Einfachheit und Zuverlässigkeit aus. Es liefert das oben beschriebene, einfach zu verlegende Bauwerkabdichtungssystem in Doppelschalenausfertigung. Aufgrund der doppelschaligen Ausführung ist es möglich, daß erfindungsgemäße System mit Leckanzeigevorrichtungen auf der Basis von Sammelrohren, Anlegen von Unterdruck oder Einbau von Probeentnahmerohren zu kombinieren.The inventive method is characterized by relative Simplicity and reliability. It delivers that above described, easy to install building waterproofing system in double shell design. Because of the double-shell Execution, it is possible that the inventive system with Leak detection devices based on manifolds, Applying negative pressure or installing sampling tubes combine.

Das erfindungsgemäße Herstellungsverfahren wird weiter opti­ miert, wenn beide Platten auf einem Zwillingsextruder und anschließendem Kalandrieren im wesentlichen gleichzeitig hergestellt und anschließend zusammengeführt sowie miteinander verschweißt werden.The manufacturing method according to the invention is further opti if both plates are on a twin extruder and subsequent calendering essentially simultaneously manufactured and then merged and together be welded.

Das Verschweißen erfolgt mittels Ultraschall und dadurch, daß dieser in die Platte durch die Ansätze eingeleitet wird. Die Ultraschalleinleitung kann erfindungsgemäß über getaktete Einzelsonotroden, deren mehrere auch parallel angeordnet sein können, erfolgen.The welding takes place by means of ultrasound and in that this is introduced into the plate through the approaches. The Ultrasound introduction can be clocked according to the invention Single sonotrodes, several of which can also be arranged in parallel can be done.

Auch ist es im Rahmen der Erfindung möglich, eine Walze über die die mit Abstandhaltern versehene Platte geführt wird, als Sonotrode auszubilden.It is also possible within the scope of the invention to roll over a roller which the plate provided with spacers is guided as Training sonotrode.

Schließlich wird gemäß der Erfindung vorgeschlagen, das Verschweißen der aufeinander zugeführten beiden Platten dadurch vorzunehmen, daß zwischen ihnen, kurz vor ihrem Zusammenführen, ein Heizkeil angeordnet wird, der sowohl die Spitzen der Abstandhalter als auch die ihnen zugewandte Fläche der zweiten, im wesentlichen glatten Fläche erwärmt und anschmilzt. Nach dem Zusammenfügen beider Platten und Erkalten erhält man die angestrebte Schweißverbindung.Finally, it is proposed according to the invention that Welding the two plates fed towards each other by making between them, just before their Merge, a heating wedge is arranged, which both the Tips of the spacers as well as the surface facing them  the second, essentially smooth surface is heated and melts. After joining both plates and cooling you get the desired welded joint.

Fig. 6 shows a (not) roller gap, the heating of the spacer and the second plate to be welded to them is carried out by means of a heating wedge.

Das erfindungsgemäße Bauwerkabdichtungssystem 1 ist in Fig. 1 dargestellt. Es besteht im wesentlichen aus einer ersten Kunststoffplatte 2 mit einstückig daran vorgesehenen Abstand­ haltern 4 und einer zweiten Platte 3, die an den Spitzen oder zunächst freien Enden der Abstandhalter 4 mit diesen ver­ schweißt ist. Das Bauwerkabdichtungssystem 1 ist aus thermoplastischem Kunststoff hergestellt, insbesondere aus Polyethylen, auch Polypropylen kommt als Werkstoff in Frage.The building waterproofing system 1 according to the invention is shown in FIG. 1. It consists essentially of a first plastic plate 2 with integral spacers 4 and a second plate 3 , which is welded to the tips or initially free ends of the spacers 4 with these ver. The building waterproofing system 1 is made of thermoplastic, in particular of polyethylene, and polypropylene can also be used as a material.

In der Fig. 1 ist ein Querschnitt durch das Bauwerkabdich­ tungssystem 1 gezeigt. Ein Schnitt senkrecht zur Zeichnungs­ ebene, vgl. Fig. 4 und 5, ergibt die gleiche Ansicht wie Fig. 1, woraus folgt, daß es sich bei dem System um ein in diesen beiden Richtungen symmetrisches Bauteil handelt. Es kann mit Plattengröße von mehreren Quadratmetern hergestellt werden. Einzelplatten werden auf der Baustelle mittels Verbindungs­ profilen zusammengesetzt, die im wesentlichen zu der ersten Platte 2 und der zweiten Platte 3 korrespondierende Ausneh­ mungen aufweisen. Auf diese Weise ist es möglich, große Flächen mit dem Bauwerkabdichtungssystem zu versehen. An den Stoßstellen können die tafelartigen Bauwerkabdichtungssysteme mit den Verbindungsprofilen verschweißt werden, um eine zuverlässige Abdichtung herbeizuführen.In Fig. 1, a cross section through the construction sealing system 1 is shown. A section perpendicular to the drawing plane, cf. FIGS. 4 and 5, results in the same view as Fig. 1, from which it follows that it is the system is a symmetrical component in these two directions. It can be made with plate size of several square meters. Individual plates are assembled on site by means of connection profiles, which essentially have corresponding recesses to the first plate 2 and the second plate 3 . In this way it is possible to provide large areas with the building waterproofing system. The panel-like building waterproofing systems can be welded to the connection profiles at the joints in order to achieve a reliable seal.

In Fig. 2 ist eine seitliche Teilansicht eines weiteren bevorzugten Ausführungsbeispiels der Erfindung gezeigt. Sie unterscheidet sich von dem Ausführungsbeispiel nach Fig. 1 dadurch, daß die zweite Platte 3 mit zusätzlichen Spreiznoppen 5 ausgestattet ist. Diese sind vorzugsweise einstückig mit der zweiten Platte 3 verbunden, ähnlich wie die Abstandhalter 4 mit der ersten Platte 2. Aus den Fig. 4 und 5 erkennt man, daß die jeweils beiden Spreiznoppen 5 etwa in einer Linie an der zweiten Platte 3 angeordnet sind und sich von dort nach oben auseinanderspreizen unter Einschluß eine Winkels von etwa 30 bis 40°. Die genaue Ausbildung dieser Noppen ergibt sich beispielsweise aus der EP 04 36 058 A1, welches Dokument insoweit zum Gegenstand der hier vorliegenden Offenbarung gemacht wird.In FIG. 2 is a partial side view of another preferred embodiment of the invention is shown. It differs from the exemplary embodiment according to FIG. 1 in that the second plate 3 is equipped with additional expanding knobs 5 . These are preferably connected in one piece to the second plate 3 , similar to the spacers 4 to the first plate 2 . From FIGS. 4 and 5 it is seen that the respective two Spreiznoppen 5 are arranged approximately in a line on the second plate 3 and extending therefrom upward spread apart including an angle of about 30 ° to 40 °. The precise design of these knobs is evident, for example, from EP 04 36 058 A1, which document is made the subject of the present disclosure in this respect.

Das erfindungsgemäße Bauwerkabdichtungssystem gemäß Fig. 1 kann in der gezeigten Form in einem beispielsweisen wannenar­ tigen Bauwerk ohne weiteres, ggf. unter Zuhilfenahme eines Klebers verlegt werden. Das Ausführungsbeispiel nach Fig. 2 wird mittels der Spreiznoppen in den frischen Beton oder einen Estrich eingebaut, wobei es zu einer besonders festen Verbin­ dung des Systems mit dem Bauwerk kommt.The structural seal system of the invention shown in FIG. 1 may be in the form shown in an exemplary wannenar term structure readily, optionally with the aid of an adhesive to be laid. The embodiment of Fig. 2 is installed by means of the expanding knobs in the fresh concrete or a screed, which leads to a particularly firm connec tion of the system with the building.

Die Fig. 3 vermittelt einen Eindruck von der Größenordnung der Abstandhalter 4 und somit auch des doppelwandigen Bauwandab­ dichtungssystems insgesamt. Sie gibt ein Detail der Fig. 2 wieder, wie der Pfeil 6 andeutet. In der Fig. 3 sind Maßan­ gaben in Millimeter angegeben. Aus der Fig. 3 ergibt sich ein weiterhin wesentliches Merkmal der Erfindung, nämlich daß auf den Abstandhaltern 4 vor dem Verschweißen mit der zweiten Platte 3 jeweils ein gegenüber dem eigentlichen Abstandhalter 4 im Durchmesser und somit auch in der Masse kleinerer Schweißnoppen 7 vorgesehen ist, der beim Verschweißen mit der zweiten Platte 3 aufschmilzt. Durch die verringerte Masse dieser Schweißnoppe 7 kann die einzubringende Schweißenergie geringgehalten werden. Fig. 3 gives an impression of the order of magnitude of the spacers 4 and thus of the double-walled Bauwandab sealing system as a whole. It shows a detail of FIG. 2, as the arrow 6 indicates. In Fig. 3, measures are given in millimeters. From Fig. 3 there is a further essential feature of the invention, namely that on the spacers 4 before welding to the second plate 3 in each case one compared to the actual spacer 4 in diameter and thus also in the mass of smaller welding studs 7 is provided, the melts when welded to the second plate 3 . Due to the reduced mass of this welding nub 7 , the welding energy to be introduced can be kept low.

Die Abstandhalter 4 sind bei den dargestellten Ausführungs­ beispielen rotationssymmetrisch ausgeführt, und zwar in Form von Kegelstümpfen. Sie können jedoch auch zylindrisch oder mit eckigem Querschnitt vorgesehen sein. Letzteres ist bei den Spreiznoppen 5 der Fall. Diese weisen in der Regel rechteckigen Querschnitt auf.The spacers 4 are rotationally symmetrical in the illustrated embodiments, in the form of truncated cones. However, they can also be provided cylindrical or with an angular cross section. The latter is the case with the expanding knobs 5 . These generally have a rectangular cross section.

In den Fig. 4 bis 6 ist das Herstellungsverfahren des Bauwerkabdichtungssystems 1 näher erläutert. Die Fig. 4 und 5 zeigen unterschiedliche Herstellungsmethoden des Gegenstands der Fig. 2. In beiden Fällen werden erste Platte 2 und zweite Platte 3 vorzugsweise direkt aus den Extrudern über Kalander einer Verbindungseinheit zugeführt. In Fig. 4 ist dies ein Walzenspalt, der von den beiden Walzen 8 und 9 gebildet wird. Die Walze 9 ist hierbei als Sonotrode ausgebildet, über die Ultraschall in die jeweils im Walzenspalt befindlichen Abstandhalter oder Ansätze 4 eingeleitet wird, wodurch es dann zu einem Verschweißen mit der anliegenden zweiten Platte 3 kommt und man das doppelwandige System gemäß Fig. 1 erhält. In Fig. 5 ist die Walze 9 durch eine Einzelsonotrode 10 ersetzt, von deren mehrere sich über die Breite der ersten Platte 2 erstrecken. Diese Sonotrode(n) 10 können, wie der Pfeil 11 andeutet, entsprechend der Vorschubgeschwindigkeit der Platten 2 und 3 getaktet werden, um jeweils einen Ab­ standhalter oder eine Reihe von Abstandhaltern 4 mit Ultra­ schall zu beaufschlagen und so die Abstandhalter 4 mit der Platte 3 zu verschweißen. Fig. 6 zeigt das Verschweißen der beiden Platten 2 und 3 mittels Wärmeeinfluß. In einem wiederum aus Walzen 8 und 9, die in diesem Fall jedoch nicht gezeigt sind, gebildeten Walzenspalt ist zwischen den beiden Platten 2 und 3 ein Heizkeil 12 vorgesehen, der beispielsweise mittels elektrischer Widerstandsheizung beheizt wird. Beim gezeich­ neten Ausführungsbeispiel liegt er auf den Schweißnoppen 5 der Abstandhalter 4 auf und bringt diese damit zum Erweichen. Weiterhin beaufschlagt er mittels Strahlungserhitzung die ihm zugewandte Oberfläche der Platte 3. Nach dem anschließenden Zusammenführen beider Platten in Richtung des Pfeiles 13 kommt es dann zu der gewünschten festen Verbindung beider Platten, sobald die aufgeschmolzenen Kunststoffbestandteile wieder abkühlen. Auf diese Weise erhält man das erfindungsgemäße Bauwerkabdichtungssystem 1.In Figs. 4 to 6, the manufacturing method of the structural seal system 1 is explained in more detail. FIGS. 4 and 5 show different methods of preparation of the article of FIG. 2. In both cases, first and second plate 2 plate 3 preferably fed directly from the extruders through calender of a connection unit. In Fig. 4 this is a nip which is formed by the two rollers 8 and 9 . The roller 9 is in this case designed as a sonotrode, via which ultrasound is introduced into the spacers or shoulders 4 located in the roller gap, which then results in welding to the adjacent second plate 3 and the double-walled system according to FIG. 1 is obtained. In FIG. 5, the roller 9 is replaced by a Einzelsonotrode 10, a plurality of which extend across the width of the first plate 2. This sonotrode (s) 10 , as indicated by the arrow 11 , can be clocked according to the feed speed of the plates 2 and 3 , in order to apply ultrasound to a spacer or a series of spacers 4, and thus the spacers 4 with the plate 3 to weld. Fig. 6 shows the welding of the two plates 2 and 3 by means of heat. In a roller gap, again formed from rollers 8 and 9 , which are not shown in this case, a heating wedge 12 is provided between the two plates 2 and 3 and is heated, for example, by means of electrical resistance heating. In the exemplary embodiment, it rests on the welding nubs 5 of the spacer 4 and thus causes them to soften. Furthermore, he acts on the surface of the plate 3 facing him by means of radiation heating. After the subsequent merging of both plates in the direction of arrow 13 , the desired firm connection of the two plates then occurs as soon as the melted plastic components cool down again. The building waterproofing system 1 according to the invention is obtained in this way.

Der Vollständigkeit halber sei auch darauf hingewiesen, daß es im Rahmen der Erfindung liegt, in eine der beiden Platten 2 und 3 eine zusätzliche Aluminiumdichtungsbahn einzuarbeiten, um hier durch die Sicherheit der Abdichtungswirkung weiter zu erhöhen.For the sake of completeness, it should also be pointed out that it is within the scope of the invention to incorporate an additional aluminum sealing membrane into one of the two plates 2 and 3 in order to further increase the safety of the sealing effect here.

Neben der beschriebenen Heizkeilschweißung und Ultraschall­ schweißung sind auch andere Schweißverfahren möglich, bei­ spielsweise ein Verschweißen mittels Infraroterwärmung.In addition to the hot wedge welding and ultrasound described welding, other welding methods are also possible at for example welding by means of infrared heating.

Der besondere Vorteil des erfindungsgemäßen Bauwerkabdich­ tungssystems besteht darin, daß es in einem Herstellungsvor­ gang kontinuierlich produziert werden kann.The particular advantage of the structure according to the invention tion system is that it is in a manufacturing process can be produced continuously.
