Description
Die Erfindung betrifft eine Einlage für Gleitfugen zwischen Ober- und Unterbau von Bauwerken, : Straßen od. dgl., welche aus Kunststoffolien besteht, die unter Vermittlung einer einen geringen Reibungsbeiwert aufweisenden Zwischenschicht aufeinanderliegen. The invention relates to an insert for slip planes between the top and base of structures: roads or the like, consisting of plastic films on one another through the intermediary of the having a low coefficient of friction intermediate layer...
Die in Bergbaugebieten vorkommenden Bodenbewegungen, insbesondere die aus der Muldenbildung sich ergebenden Horizontalbewegungen, wirken sich in Gebäude- und Brückenfundamenten, Straßenunterbauten od. dgl. in erheblichen, im voraus in der Regel nicht erfaßbaren Beanspruchungen aus. Es ist ) ·, deshalb vielfach üblich, die Fundamente mit einer zusätzlichen starken Zerrbewehrung auszustatten, .die jedoch den Bau meist beträchtlich verteuert.. . ,The ground movements occurring in mining areas, especially those resulting from the formation of hollows The resulting horizontal movements affect building and bridge foundations, road substructures or the like in considerable stresses that are usually not detectable in advance. It is ) ·, therefore it is common practice to equip the foundations with additional strong distortion reinforcement, .the however, the construction is usually considerably more expensive ... ,
Um diesem Übel abzuhelfen, hat man auch bereits zwischen Fundament und Bauwerk Gleitfugen zur Herabminderung der . Reibungswerte vorgesehen, doch ist bei allen diesen Lösungen entweder die Herabminderung der Reibungswerte unbefriedigend, oder die Gleitfugenausbildung ist mit derart hohen Kosten verbunden, daß die Einsparung an Baustoffen in keinem Verhältnis zu den notwendigen Aufwendungen steht.In order to remedy this evil, sliding joints are already in place between the foundation and the structure Reduction of the. Friction values are provided, but in all of these solutions either Reduction of the friction values is unsatisfactory, or the sliding joint formation is so high Costs associated that the saving in building materials is out of proportion to the necessary Expenses stands.
Es ist bereits eine Einlage aus Kunststoffolien vor- as geschlagen worden, zwischen welche zur Minderung * des Reibwertes eine Zwischenschicht eingebracht ist, beispielsweise Flockengraphit, Talkum oder Paraffin.There is already an insert made of plastic foils beaten, between which an intermediate layer is inserted to reduce * the coefficient of friction, for example flake graphite, talc or paraffin.
Diese Anordnung hat sich im großen und ganzen gut bewährt, jedoch ist das Einbringen der Zwischenschicht außerordentlich umständlich und aufwendig, insbesondere dann, wenn-eine in etwa gleichmäßige Verteilung dieser Zwischenschicht erreicht werden , soll, was für eine gute Gleitwirkung unerläßlich ist." "' Als nachteilig erweist es sich auch, daß die Zwischenschicht keine feste Verbindung mit den als Träger dienenden Kunststoffolien besitzt, so daß sich die Zwischenschicht je nach den gegebenen Beanspruchungen seitlich zwischen den Kunststoffolien herausschieben und Staub usw. je nach der Bewegung der Einlage in die Zwischenschicht eindringen kann, was zu einer Beeinträchtigung der Lebensdauer und - · der Gleitwirkung führt.This arrangement has proven itself by and large, but the introduction of the intermediate layer is extremely laborious and expensive, especially if an approximately uniform distribution of this intermediate layer is to be achieved, which is essential for a good sliding effect. "" 'To be disadvantageous, it also proves that the intermediate layer has no fixed connection with the serving as the carrier plastic, so that the intermediate layer is pushed out according to the given loads laterally between the plastic films and dust, etc., depending on the movement of the insert in the intermediate layer can penetrate, which leads to an impairment of the service life and the sliding effect.
Bekannt war es weiterhin, Kunststoffolien aus Polyäthylen bereits bei ihrer Herstellung mit Zusätzen zu versehen, welche eine gute Gleitwirkung besitzen und derartige Folien in Form von Schläuchen als Fugeneinlagen zu verwenden. An Stelle von Polyäthylenfolien können auch Polytetrafluoräthylen- und Polyvenylchloridfolien verwendet werden, jedoch so sind die beizufügenden Zusätze zur Herabminderung des Gleitwertes je nach Beschaffenheit der Trägerfolien auszusuchen.It was also known that plastic films made of polyethylene with additives during their manufacture to provide, which have a good sliding effect and such films in the form of tubes to be used as joint inlays. Instead of polyethylene foils, polytetrafluoroethylene and polyvinyl chloride films can be used, but so are the additives to be added to reduce the sliding value depending on the nature of the carrier film to choose.
Diese bekannte Anordnung hat also den Nachteil, daß je nach Beschaffenheit der Trägerfölie, welche nach ganz bestimmten Gesichtspunkten, wie Druckfestigkeit, Temperaturbeständigkeit usw., ausgewählt werden muß, auch jeweils die beizufügenden Komponenten zur Erzielung einer guten Gleitwirkung entsprechend ausgewählt und geändert werden müssen, was vergleichsweise aufwendig ist.This known arrangement has the disadvantage that, depending on the nature of the carrier film, which selected according to very specific criteria, such as compressive strength, temperature resistance, etc. must be, including the components to be added in each case to achieve a good lubricating effect must be selected and changed accordingly, which is comparatively expensive.
Von diesem Stand der Technik ausgehend, liegt der Erfindung die Aufgabe zugrunde, eine Einlage für Gleitfugen zu schaffen, welche eine Herabminderung des Reibungswertes auf geringste Werte ermöglicht, und überdies eine einfache Herstellung und Anbringung gewährleistet ist.'Proceeding from this prior art, the invention is based on the object of an insert to create sliding joints which enable the friction value to be reduced to the lowest possible values, and, moreover, simple manufacture and installation is guaranteed. '
Gemäß der Erfindung wird dies dadurch erreicht, daß die Folien zur Bildung der Zwischenschicht an ihren einander zugekehrten Seiten mit Teilchen von molekularer Größenordnung aus Kunststoff der Gruppe der Polyolefine beschichtet sind. Die Kunststoffolien sind nach Druckfestigkeit und Temperaturbeständigkeit usw. ausgewählt, wobei die Oberfläche jedoch nicht zu rauh ist. Auf diese eine Seite dieser Kunststoffolien werden Teilchen, z. B. Niederdruckpofyäthylenteilchen: in feinster Verteilung aufgesprüht, und zwar liegt die Größe der Teilchen im Molekularbereich, beispielsweise sind diese hexamolekular. Die einzelnen Teilchen der aufgebrachten Schicht werden untereinander und an der Oberfläche der Folien durch Oberflächenkräfte gehalten, welche ganz beträchtlich größer sind als die auftretenden Beanspruchungen, z. B. durch Scherkräfte, so daß diese nicht abgerieben werden können und die Einlage infolgedessen eine hohe Lebensdauer besitzt. Außerdem ergibt sich eine sehr starke Herabminderung des Reibungswertes, und zwar einmal be- f dingt durch Ausgleich der Unebenheiten der Oberflächen der Kunststoffolien, welche fertigungstechnisch bedingt sind, _und zum anderen durch die Auswahl der für*" die Beschichtung verwendeten Teilehen aus der Gruppe der Polyolefine nach ihren Gleiteigenschaften. Die Einlagen können vorgefertigt zur Baustelle angeliefert werden, so daß aiese in kürzester Zeit verlegt-werden können.According to the invention this is achieved in that the films to form the intermediate layer their facing sides with particles of molecular size made of plastic the Group of polyolefins are coated. The plastic films are according to compressive strength and temperature resistance etc., but the surface is not too rough. On this one side of this Plastic films are particles, e.g. B. Low pressure polyethylene particles: sprayed on in extremely fine distribution, the size of the particles being in the molecular range, for example they are hexamolecular. The individual particles of the applied layer are among each other and on the surface of the foils held by surface forces which are considerably greater than those that occur Stresses, e.g. B. by shear forces so that they cannot be rubbed off and the insert consequently has a long service life. In addition, there is a very strong degradation the coefficient of friction, on the one hand due to the compensation of the unevenness of the surfaces the plastic foils, which are due to production engineering, _and on the other hand by the Selection of the parts used for * "the coating from the group of polyolefins according to theirs Sliding properties. The inlays can be delivered to the construction site prefabricated so that they can be used in can be relocated in a very short time.
Die Herstellung der Einlagen ist außerordentlich einfach, da diese mit einem .Minimum an Material- und Arbeitsaufwand durchgeführt werden kann, wobei unabhängig von der Beschaffenheit des Trägermaterials immer die gleiche Vorrichtung zum Aufbringen der Teilchen in molekularer Größenordnung verwendet werden kann, wobei auch diese Teilchen immer gleich bleiben und nicht der Beschaffenheit der jeweiligen Trägerfolie angepaßt werden-.niüssen.The production of the insoles is extremely easy, as they are made with a minimum of material and workload can be performed, regardless of the nature of the substrate always the same device for applying the particles on a molecular scale can be used, whereby these particles always remain the same and not the nature be adapted to the respective carrier film-.nuts.
Mit einer Einlage gemäß der Erfindung lassen sich-Reibungswerte von unter 0,1 beispielsweise 0,05 und weniger erzielen, und zwar über einen vergleichsweise langen Zeitraum, was mit den bekannten | Einlagen für Gleitfugen nicht möglich ist.With an insert according to the invention, friction values of less than 0.1, for example 0.05 and achieve less, over a comparatively long period of time, what with the known | Deposits for sliding joints is not possible.
Diese starke Herabsetzung des Reibungswertes hat erhebliche Vorteile hinsichtlich der Bemessung der Bewehrung des Bauwerkes zur Folge, so daß auch in dieser Hinsicht eine Materialersparnis erzielt wird.This great reduction in the coefficient of friction has considerable advantages in terms of the dimensioning of the Reinforcement of the structure as a result, so that material savings are also achieved in this regard.
