Description

Die Erfindung bezieht sich auf eine Kunststoffplatte, insbesondere zum Auskleiden von Betonbauteilen, vorzugsweise aus thermoplastischem Kunststoff, die auf einer Seite mit Ansätzen versehen ist.The invention relates to a plastic plate, in particular for lining concrete components, preferably Made of thermoplastic plastic with one side Approaches is provided.

Eine derartige Kunststoffplatte ist beispielsweise aus der EP-A-0 436 058 bekannt.Such a plastic plate is for example from EP-A-0 436 058 known.

Betonschutzplatten aus Kunststoff, sogenannte Noppenplatten, finden insbesondere Anwendung im Betonbehälterbau, wenn es gilt, flüssigkeits- und auch gasdichte, chemikalienresistente Behälter zu erstellen. Die Kunststoffplatten bilden die Auskleidung solcher Behälter. Sie erbringen die Beständigkeit gegen die Chemikalien und Flüssigkeiten. Die mechanische Festigkeit der Gesamtkonstruktion wird im wesentlichen von der Betonkonstruktion erbracht. Schwierigkeiten bereitet in aller Regel die Verbindung der Kunststoffplatten mit der Betonkonstruktion, da eine glatte Kunststoffplatte keine feste mechanische Verbindung mit dem Beton eingeht. Die Zurhilfenahme von Klebern führt zu keinen langfristig zufriedenstellenden Ergebnissen. Concrete protection plates made of plastic, So-called knobbed plates are used in particular Concrete container construction, if applicable, liquid and gas tight, to create chemical resistant containers. The Plastic plates form the lining of such containers. They provide resistance to chemicals and Liquids. The mechanical strength of the overall construction is essentially from the concrete structure rendered. The connection usually causes difficulties of the plastic plates with the concrete structure, because a smooth plastic plate no firm mechanical connection with the concrete. The use of glue does not lead to satisfactory long-term results.

Aus diesem Grunde sind verschiedene Verankerungselemente, auch mit Hinterschneidungen, vorgeschlagen worden, die auf einer Seite der Kunststoffplatte angebracht und bei der Herstellung des Behälters im Bereich seiner zu schützenden Fläche, in der Regel seiner Innenfläche, einbetoniert werden. Auf diese Weise wird die erwünschte feste Verbindung zwischen Kunststoffplatte und Betonkonstruktion erreicht.For this reason, different anchoring elements are also with undercuts that have been suggested on attached to one side of the plastic plate and at the Manufacture of the container in the area to be protected Surface, usually its inner surface, are concreted. In this way, the desired firm connection reached between plastic plate and concrete structure.

In den Unterlagen der europäischen Patentanmeldung EP-A-0 436 058 A1 ist ein wirtschaftlich besonders günstiges Verfahren zur Herstellung von Noppenplatten aus Kunststoff sowie eine derartige Noppenplatte beschrieben. Es geht dort insbesondere um die einstückige Herstellung von hinterschnittene Noppen aufweisenden Kunststoffplatten, die sich durchaus bewährt haben.In the documents of the European patent application EP-A-0 436 058 A1 is an economically particularly advantageous process for Manufacture of nub panels made of plastic and a described knobbed plate. It is particularly there around the one-piece production of undercut Plastic plates with pimples, which are quite have proven.

Es hat sich indessen gezeigt, daß solche Kunststoffplatten, die in der Regel aus dunklem bis schwarzem Kunststoff bestehen, besondere Vorkehrungen auf der Baustelle und insbesondere während ihres Einbaus in die Betonkonstruktion zum Ausgleich relativ starker Wärmedehnungen erfordern, insbesondere wenn der Einbau bei Sonneneinstrahlung erfolgt. Die Kunststoffplatten werden auf die Schalung der Betonkonstruktion aufgenagelt und müssen dann zur Vermeidung übermäßiger Wärmedehnung gegen Sonneneinstrahlung geschützt werden. Außerdem sind bei diesen bekannten Kunststoffplatten mechanische Beschädigungen, auch im eingebauten Zustand, nur recht schwer erkennbar. Im Interesse der Sicherheit sind aber solche Beschädigungen tunlichst zu reparieren.However, it has been shown that such plastic sheets, which are usually made of dark to black plastic, special precautions on site and in particular during their installation in the concrete structure to compensate for relatively strong thermal expansion, especially if it is installed in direct sunlight. The plastic sheets are on the formwork Concrete structure nailed down and then have to be avoided excessive thermal expansion protected against sunlight become. In addition, these known plastic plates mechanical damage, even when installed Condition, hardly recognizable. In interest however, such damage is as safe as possible repair.

Die Aufgabe der Erfindung besteht somit darin, eine Kunststoffplatte der eingangs genannten Art zu schaffen, die eine vergleichsweise geringe bis vernachlässigbare Wärmeausdehnung auch bei Sonneneinstrahlung zeigt und die darüber hinaus eine Signalfunktion beim Vorliegen ernsthafterer mechanischer Schädigungen oder von Rissen erbringt.The object of the invention is therefore a plastic plate of the type mentioned at the outset to create the a comparatively low to negligible thermal expansion also shows in sunlight and the above also a signaling function when more serious mechanical damage or cracks.

Diese Aufgabe ist gemäß der Erfindung dadurch gelöst, daß die Platte zwei Schichten umfaßt, wobei die die Ansätze aufnehmende Schicht wärmereflektierend ausgebildet ist und die gegenüberliegende Schicht aus Material mit zur Farbe der wärmereflektierend ausgebildeten Schicht unterschiedlicher Farbe besteht.This object is achieved according to the invention in that the plate comprises two layers, which are the approaches receiving layer is heat reflective and the opposite layer of material with the color of the heat reflective layer different Color exists.

Zweckmäßige Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.Appropriate developments of the invention are the subject of dependent claims.

Bei der Vorbereitung zum Einbau der erfindungsgemäßen Kunststoffplatte wird diese auf die Schalung der zu erstellenden Betonkonstruktion aufgebracht, in der Regel aufgenagelt. In diesem Stadium brauchen wegen der wärmereflektierenden Ausbildung der der möglichen Sonneneinstrahlung zugewandten Schicht keine besonderen Vorkehrungen mehr getroffen werden, um einen Einfall des Sonnenlichtes soweit wie möglich zu verhindern. Durch die wärmereflektierende Ausbildung der obenliegenden Schicht, ggf. einschließlich der dort vorhandenen Noppen, kommt es zu einer wesentlich geringeren Erwärmung der Kunststoffplatte als bisher und somit auch nur noch zu einer technisch praktisch vernachlässigbaren Wärmeausdehnung der Platte. Besondere Schutzmaßnahmen zur Verhinderung der Erwärmung der Platte vor ihrem Einbau können somit entfallen. Gleichzeitig wird aufgrund der unterschiedlichen Farbgebung der die Noppen oder Ansätze aufweisenden Schicht und der gegenüber- oder anliegenden Schicht eine Signalwirkung dann erzielt, wenn insbesondere im eingebauten Zustand die gegenüberliegende Schicht, die dann die oben liegende Deckschicht ist, eine gravierende mechanische Beschädigung aufweist. In diesem Fall ist die reflektierende Schicht wegen ihrer unterschiedlichen Farbe gegenüber der anliegenden weiteren Schicht sichtbar, sodaß ein Hinweis auf eine anstehende Reparatur gegeben ist.When preparing to install the invention Plastic sheet is this on the formwork to be created Concrete structure applied, usually nailed on. Need at this stage because of the heat reflective Training of the possible sun exposure facing layer no longer take any special precautions be so far as an incidence of sunlight to prevent as possible. Due to the heat reflective Formation of the top layer, including if necessary of the knobs there, there is a significant less heating of the plastic plate than before and thus only a technically negligible one Thermal expansion of the plate. Special protective measures to prevent heating of the plate their installation can thus be omitted. At the same time is due the different colors of the knobs or Appropriate layer and the opposite or adjacent Layer has a signal effect if in particular when installed, the opposite Layer, which is then the top layer, a shows serious mechanical damage. In this Case is the reflective layer because of its different Color compared to the other one Layer visible, so that an indication of an upcoming repair given is.

Erfindungsgemäß empfiehlt es sich, daß die die Ansätze oder Noppen aufnehmende Schicht aus vergleichsweise hellem Kunststoff und die gegenüberliegende Schicht aus vergleichsweise dunklem Kunststoff besteht. Die helle Kunststoffschicht wirkt im angestrebten Sinne grundsätzlich wärmereflektierend. Sie ist im Falle der möglichen Beschädigung dann auch gegenüber der dunklen Kunststoffschicht besonders gut erkennbar.According to the invention it is recommended that the approaches or Pimple-absorbing layer made of comparatively light Plastic and the opposite layer of comparatively dark plastic. The light plastic layer basically works in the desired sense heat reflective. It is in case of possible damage then also against the dark plastic layer particularly well recognizable.

Nach einem weiteren Merkmal der Erfindung empfiehlt es sich, daß die Ansätze hinterschnitten und einstückig an der Platte vorgesehen sind. Auf diese Weise ergibt sich zum einen eine wirtschaftliche Herstellungsmöglichkeit der Platte, zum anderen ist durch die Hinterschneidungen eine besonders gute Verankerungsmöglichkeit im Beton gegeben.According to a further feature of the invention, it is recommended themselves that the approaches undercut and in one piece on the Plate are provided. This results in an an economical production possibility of Plate, on the other hand is one due to the undercuts particularly good anchoring option in concrete.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigen:

  • Fig. 1 eine teilweise Seitenansicht der erfindungsgemäßen Kunststoffplatte;
  • Fig. 2 eine Draufsicht auf den Gegenstand der Fig. 1 und
  • Fig. 3 eine teilweise Seitenansicht des Gegenstandes der Fig. 1.
  • An embodiment of the invention is shown in the drawing and will be described in more detail below. Show it:
  • Figure 1 is a partial side view of the plastic plate according to the invention.
  • Fig. 2 is a plan view of the subject of Fig. 1 and
  • 3 is a partial side view of the subject of FIG. 1.
  • Aus der Fig. 1 ergibt sich bereits grundsätzlich der Aufbau der erfindungsgemäßen Betonschutzplatte mit Signal- bzw. Reflexionsschicht. Die Kunststoff- oder Noppenplatte 3 besteht aus einer wärmereflektierenden Schicht 1 mit Ansätzen oder Noppen 10, die vorzugsweise einstückig mit der wärmereflektierenden Schicht 1 hergestellt sind. Fest verbunden mit der wärmereflektierenden Schicht 1 ist eine weitere Schicht 2, die in einer kontrastierenden Farbe zur wärmereflektierenden Schicht ausgeführt ist. Aus praktischen Gründen ist die wärmereflektierende Schicht zusammen mit den Noppen 10 vorzugsweise aus Kunststoff heller Farbe, etwa weiß, hergestellt. Die anliegende Schicht 2 ist in der Regel in der Farbe dunkelbraun bis schwarz ausgeführt. Bei dieser Farbgebung werden die oben ausgeführten Wirkungen erreicht. Bei Sonneneinstrahlung auf die helle Schicht 1 kommt es zu einer ausgeprägten Wärmereflexion. Eine unzulässige Wärmeausdehnung der Kunststoffplatte wird somit vermieden. Sollte es bei dem rauhen Baustellenbetrieb zu einer Beschädigung dieser wärmereflektierenden Schicht oder auch der dunklen Schicht 2 kommen, so ist dies jeweils aufgrund der kontrastierenden Farbgebung gut erkennbar, sodaß eine u.U. notwendige Reparatur angezeigt wird.1 already shows the basic structure the concrete protective plate according to the invention with signal or Reflective layer. The plastic or knobbed plate 3 consists of a heat-reflecting layer 1 with approaches or knobs 10, which are preferably in one piece with the heat reflective layer 1 are made. Firmly connected with the heat reflecting layer 1 is one another layer 2, which is in a contrasting color heat reflective layer is executed. For practical For reasons, the heat reflective layer is together with the knobs 10 preferably made of plastic of light color, about white. The adjacent layer 2 is in the Usually dark brown to black in color. At this coloring will have the effects set out above reached. When exposed to sunlight on the light layer 1 there is a pronounced heat reflection. An impermissible Thermal expansion of the plastic plate is thus avoided. Should it be with the rough construction site operations damage to this heat reflecting layer or dark layer 2 also come, this is due in each case the contrasting color scheme clearly recognizable, so a possibly necessary repair is displayed.

    Die Fig. 1 bis 3 zeigen ein Ausführungsbeispiel der erfindungsgemäßen Kunststoffplatte, wobei in Fig. 3 eine Einheit eines Ansatzes oder einer Noppe gezeigt ist, während zwei weitere identische Ansätze lediglich mittels zweier Symmetrielinien zeichnerisch angedeutet sind. Diese angedeuteten Ansätze sind identisch mit dem vollständig gezeichneten Ansatz oder der Ansatzeinheit 10 ausgeführt. Wie aus den erwähnten Fig. 1 bis 3 ersichtlich, besteht ein Ansatz 10 aus zwei Flügeln oder Flügelelementen 13, die beim gezeichneten Ausführungsbeispiel so zur Schicht 1 angeordnet sind, daß ihre Hauptachsen bezüglich der Senkrechten zur Schicht 1 einen Winkel von 30° bzw. 40° einschließen. Sämtliche Ansätze 10 sind in der gleichen Weise bezüglich der Schicht 1 vorgesehen. Wie sich insbesondere aus der Draufsicht nach Fig. 2 und der Seitenansicht nach Fig. 3 ergibt, ist im Winkelraum von 70° zwischen den beiden Flügeln 13 ein Steg 15 angebracht. Er dient einer Fixierung der Stellung der beiden Flügel 13 zueinander, was insbesondere beim Entformungsvorgang der Ansatzeinheiten 10 von Vorteil ist, wo eine gewisse Kraft auf die Ansätze oder Ansatzeinheiten 10 ausgeübt werden muß, um sie aus den Ausnehmungen der Herstellungskalander herauszunehmen. Weiterhin ist dieser Steg 15 aber auch beim Einbetonieren der erfindungsgemäßen Kunststoffplatte von Bedeutung, wenn dort die Massenkräfte des noch nicht ausgehärteten Betons auf die Flügel 13 einwirken. Auch hierbei übernehmen die Stege 15 der Ansätze 13 eine Aussteifungsfunktion und gewährleisten so eine Beibehaltung der hinterschnittenen Gesamtform der Ansätze 10, um eine zuverlässige Verankerung der Ansätze und somit der gesamten Kunststoffplatte 3 in dem Betonteil zu gewährleisten.1 to 3 show an embodiment of the invention Plastic plate, in Fig. 3 a unit one neck or pimple is shown while two further identical approaches using only two lines of symmetry are indicated in the drawing. These alluded to Approaches are identical to the fully drawn one Approach or the approach unit 10 executed. Like from the 1 to 3 can be seen, there is an approach 10 of two wings or wing elements 13, the drawn Embodiment are arranged to layer 1, that their major axes are perpendicular to the layer 1 enclose an angle of 30 ° or 40 °. All approaches 10 are in the same way with respect to layer 1 intended. As can be seen in particular from the top view Fig. 2 and the side view of FIG. 3 is in Angular space of 70 ° between the two wings 13 a web 15 attached. It serves to fix the position of the two wings 13 to each other, especially during the demolding process the approach units 10 is advantageous where a certain force on the attachments or attachment units 10 must be exercised to remove them from the recesses of the manufacturing calender to take out. This bridge is also 15 but also when concreting the invention Plastic plate important if there are the mass forces act on the wing 13 of the not yet hardened concrete. Here, too, the webs 15 of the approaches 13 take over a stiffening function and thus ensure retention the undercut overall shape of the approaches 10 a reliable anchoring of the approaches and thus the to ensure the entire plastic plate 3 in the concrete part.

    Um eine Vorstellung der Größe der Ansätze 10 zu vermitteln, sind in Fig. 2 beispielsweise einige Maßangaben in mm angegeben. Es ergibt sich hierbei, daß die Breite der Flügel 13 etwa 11 mm beträgt, der Abstand der Ansätze zueinander beträgt 40 mm, die seitliche Versetzung zweier Ansätze etwa 29 mm. Die Breite des Steges 15 liegt bei etwa 4 mm, die Gesamtbreite einer Ansatzeinheit 10, die aus zwei Flügeln gebildet ist, bei etwa 20 mm. Die seitliche Versetzung zweier Ansatzeinheiten 10 liegt bei 29 mm. To give an idea of the size of approaches 10, 2, for example, some dimensions are given in mm. It follows that the width of the wing 13th is about 11 mm, the distance between the approaches is 40 mm, the lateral offset of two approaches 29 mm. The width of the web 15 is about 4 mm Total width of an attachment unit 10, which consists of two wings is formed at about 20 mm. The lateral displacement two attachment units 10 is 29 mm.

    Fig. 2 zeigt auch, daß die seitliche Versetzung der Flügel 13 einer Ansatzeinheit 10 praktisch über ihre gesamte Breite von 11,3 mm abzüglich der Dicke des Steges erfolgt. Diese seitliche Versetzung kann jedoch auch geringer gewählt werden, doch ergibt sich bei der gezeigten Anordnung ein Optimum an Wirksamkeit der Ansatzeinheit 10 als Verankerungselement sowie an Entformbarkeit aus der Walze des Kalanders. Weiterhin ist die Form der Flügel nicht auf die gezeigte flächige Ausführung beschränkt. Die einzelnen Flügel 13 können im Querschnitt gesehen vielmehr neben der gezeigten rechteckigen Form auch rund, oval sowie quadratisch ausgeführt werden.
    Als Material für die Kunststoffplatte kommen Polyvinylchlorid, Polypropylen, Polyethylen, Polyvinylidenfluorid sowie E-CTFE in Frage.
    Fig. 2 also shows that the lateral displacement of the wings 13 of a shoulder unit 10 takes place practically over its entire width of 11.3 mm minus the thickness of the web. This lateral offset can, however, also be selected to be smaller, but in the arrangement shown there is an optimum in the effectiveness of the attachment unit 10 as an anchoring element and in the ability to be removed from the roll of the calender. Furthermore, the shape of the wing is not limited to the flat design shown. Viewed in cross-section, the individual wings 13 can also be made round, oval and square, in addition to the rectangular shape shown.
    Polyvinyl chloride, polypropylene, polyethylene, polyvinylidene fluoride and E-CTFE can be used as the material for the plastic plate.

    Die Herstellung der erfindungsgemäßen Kunststoffplatte erfolgt in analoger Weise wie in der EP 0 436 058 A1 beschrieben. Zusätzlich zur Herstellung der dort beschriebenen Noppenplatte, im vorliegenden Fall aus hellem bis weißem thermoplastischen Kunststoff, wird auf einem zweiten Kalander die dunkle bis schwarze Schicht 2 oder Platte erzeugt und anschließend dem in Transportrichtung gesehen letzten Walzenspalt des Kalanders zur Herstellung der wärmereflektierenden, mit Noppen versehenen Schicht 1 zugeführt. Auf diese Weise kommt es zu einer innigen Verbindung oder Verschweißung der Schichten 1 und 2. The plastic plate according to the invention is produced in a manner analogous to that described in EP 0 436 058 A1. In addition to the production of those described there Knob plate, in the present case from light to white thermoplastic, is on a second Calender the dark to black layer 2 or plate generated and then seen in the direction of transport last nip of the calender to produce the heat reflective, provided with nubs layer 1. In this way there is an intimate connection or welding layers 1 and 2.

    Durch die Verwendung eines dunklen bis schwarzen Kunststoffes für die Schicht 2 ist die UV-Beständigkeit der erfindungsgemäßen Kunststoffplatte im eingebauten Zustand gegeben, wobei, wie erwähnt, diese Schicht 2 die Außenschicht der Kunststoffplatte bezüglich der Betonkonstruktion bildet.By using a dark to black plastic for layer 2 is the UV resistance of the invention Given plastic plate when installed, whereby, as mentioned, this layer 2 is the outer layer the plastic plate with respect to the concrete structure.
