Abstract
Description
Die Erfindung berifft ein Verfahren zur Oberflächenvergütung bzw. Oberflächenreparatur von Tafeln zur Verwendung bei der Formgebung von Betonbauteilen, bestehend aus einer biegesteifen Platte mit zumindest einer dem zu formenden Betonbauteil oder Transportgut zugewandten Nutzseite.The invention relates to a method for surface treatment or Surface repair of panels for use in shaping Concrete components consisting of a rigid plate with at least one of them forming concrete component or cargo side facing the cargo.
Tafeln der vorgenannten Art bestehen üblicherweise aus Holz. Sie sind während der bestimmungsgemäßen Verwendung sowie bei unsachgemäßer Lagerung häufig der Einwirkung von Nässe ausgesetzt, was quellungsbedingte Formveränderungen zur Folge haben kann. Die Wiederverwendbarkeit derartiger Tafeln ist dadurch wenig befriedigend. Sie ist darüberhinaus durch einen erheblichen Reinigungsaufwand belastet, weil der in flüssigem Zustand mit der Oberfläche in Berührung gebrachte Beton oder Schmutz in erheblichem Maße dazu neigt, sich in der nach außen offenen Porenstruktur des Holzes festzusetzen.Boards of the aforementioned type are usually made of wood. You are during the Intended use and improper storage often the Exposure to moisture, which causes swelling-related changes in shape Can have consequences. The reusability of such boards is therefore little satisfying. It is also due to a considerable cleaning effort because the concrete is brought into contact with the surface in a liquid state or dirt to a considerable extent tends to open out Pore structure of the wood.
Häufig kommt es dazu, daß festgesetzte Betonbestandteile beim Ausschalen aus der Oberfläche des frisch hergestellten und noch mechanisch labilen Betonbaueils herausgebrochen werden, was dessen Oberflächengüte belastet und aufwendige und zumeist wenig dauerhafte Reparaturen nach sich zieht.It often happens that fixed concrete components when stripping from the Surface of the freshly made and still mechanically unstable concrete part be broken out, what burdens its surface quality and complex and mostly results in little permanent repairs.
Es ist bereits bekannt, zur Vermeidung der diesbezüglichen Nachteile auf die Oberfläche von Tafeln aus Holz eine Farb- oder Wachsbeschichtung oder andersartige Schicht aufzubringen (DE-OS 23 57 516, DE 31 17 861 C2, G 85 25 341.3, EP 0353637 A1). Die Dauerhaftigkeit von derartigen Beschichtungen ist jedoch wenig befriedigend. Die Beschichtungen bedürfen der ständigen Pflege.It is already known to avoid the disadvantages in this regard Surface of wooden boards a paint or wax coating or otherwise Apply layer (DE-OS 23 57 516, DE 31 17 861 C2, G 85 25 341.3, EP 0353637 A1). However, the durability of such coatings is unsatisfactory. The coatings require constant care.
Betonschaltafeln, wie sie derzeit von der Industrie verwendet werden haben eine sehr geringe Zyklenzahl, das bedeutet, daß diese im Bereich der Sichtbetonherstellung nur vier- bis fünfmal zur Anwendung kommen können. Sodann erfolgt die Anwendung in Bereichen, die eine anschließende Veredlung der Betonoberfläche erfahren. Die Aufarbeitung solcher Betonschaltafeln zum Wiedereinsatz im Sichtbetonbereich ist zur Zeit mit 4/5 des Neupreises sehr teuer und zumeist aufwendig. In der Regel werden neue Materialien wie Lacke, Expoxidharze oder Kunststofffolien zur primären Veredlung oder zum Reparatureinsatz verwendet. Wie bereits in der Offenlegungsschrift DE 42 01 319 A1 beschrieben eignen sich für eine dauerhafte Beschichtung insbesondere Polyolefine und hier insbesondere Polyethylen. Der Erfindung liegt die Aufgabe zugrunde ein Verfahren aufzuzeigen, welches universell für die Verwendung von polymeren Abfallstoffen an Baustellen, Hersteller- oder Reparaturbetrieben für Schalungselemente Einsatz finden kann und hierbei einfach und kostengünstig zu betreiben ist. Es wird nun eine Einsatzstoff und ein Verfahren zu dessen Verarbeitung vorgeschlagen, welches derzeit sehr günstig zu beschaffen ist, da es sich um Verpackungsmaterialien aus dem Stoffkreislauf des Dualen System Deutschland handelt. Dies sind zum einen Granulate, wie sie beispielsweise im Bremer Hochofenprozess zur Befeuerung eingesetzt werden bzw. Polyolefin und Polypropylenfolienverpackungen wie sie derzeit in wachs- und paraffinerzeugenden Betrieben eingesetzt werden. Der Vorteil des vorgeschlagenen Verfahrens besteht zum einen in der kostengünstigen Materialbasis, zum anderen muß kein Kleber oder Bindeschicht zum Aufbringen der Materialien verwendet werden.Concrete switchboards currently used by industry have a very low number of cycles, which means that this is only in the field of exposed concrete production can be used four to five times. Then the application takes place in Areas that undergo subsequent finishing of the concrete surface. The Refurbishment of such concrete switchboards for re-use in exposed concrete is for Time with 4/5 of the new price very expensive and mostly expensive. Usually will new materials such as paints, epoxy resins or plastic films for primary finishing or used for repairs. As already in the published patent application DE 42 01 319 A1 described are particularly suitable for permanent coating Polyolefins and especially polyethylene. The object of the invention is to achieve this to demonstrate a method that is universal for the use of polymer waste on construction sites, manufacturers or repairers for Formwork elements can be used and easily and inexpensively operate. It now becomes a feedstock and a process for its processing proposed, which is currently very cheap to procure because it is Packaging materials from the material cycle of the Dual System Germany is. On the one hand, these are granules, such as those used in Bremen Blast furnace process can be used for firing or polyolefin and Polypropylene film packaging as currently in wax and paraffin-producing Companies are used. The advantage of the proposed method is one in the inexpensive material base, on the other hand no glue or Binding layer can be used to apply the materials.
Handelt es sich um unbeschichtete neue Schaltafelemente könne diese direkt verwendet werden, handelt es sich um zur Reparatur eingebrachte Schaltafelemente müssen diese wie üblich von der Trennschicht (Lack, Wachs) befreit und aufgerauht werden. Sodann werden die Schaltafelemente vorgewärmt auf eine Temperatur zwischen 50 und 180°C, durch diese oberflächliche Vorwärmung wird eine sehr gute Haftung mit dem Recyclingmaterial erziehlt. Das Schaltafelement wir dann unter eine Schmelzeinheit gefördert und mit Recyclatmasse übergossen. Die Temperatur dieser Masse beträgt zwischen 260 und 440°C. Zur Glättung dieser Masse wird eine Metallrolle oder eine Cuttereinheit mit einer Temperatur zwischen 260 und 440°C über die Oberfläche gezogen, bzw. die Schalplatte unter diesem Werkzeug hindurchtransportiert. Besonders einfach gestaltet sich das Verfahren bei Systemschaltafeln, da diese einen seitlichen überstand der Metallhalterung über die Holzoberfläche aufweisen, der als Randbegrenzung für die aufzubringende Masse verwendet werden kann. Durch dieses Verfahren ist es ebenfalls sehr einfach möglich, beschädigte Schaltafeloberflächen, Risse, Ausbrüche auszugleichen und somit diese Elemente wieder im Sichtbetonbereich einzusetzen.If new uncoated formwork elements are involved, they can be used directly are used, switchboard elements brought in for repair As usual, they must be freed from the separating layer (varnish, wax) and roughened become. The formwork elements are then preheated to a temperature between 50 and 180 ° C, this superficial preheating results in a very good one Liability is established with the recycling material. The switching element is then under one Pumped melt unit and poured with recycled material. The temperature of this Mass is between 260 and 440 ° C. To smooth this mass, a Metal roll or cutter unit with a temperature between 260 and 440 ° C above pulled the surface, or the formwork sheet under this tool transported through. The process is particularly simple System control panels, as these protrude laterally from the metal bracket over the Have wood surface, as a boundary for the mass to be applied can be used. This procedure also makes it very easy to compensate for damaged formwork surfaces, cracks, breakouts and thus these Reinstall elements in the exposed concrete area.
