Abstract

The cover may be placed on top of green concrete, especially a freshly poured floor, to protect it from the rain and prevent damage by people walking over it. The cover may consist of a roll of e.g. plastics material with a number of ribs formed in it. There may be alternate wide ribs (luftrippe), which may be filled with compressed air, and narrow ribs (wasserrippe) which may be filled with water under pressure. The ribs, when inflated, impart resistance to bending in one direction.

Description

Diese Schutzabdeckung besteht aus zwei Teilen.This protective cover consists of two parts.

Teil I ist eine 1 lagige Kunststoffolie von 50-200 my Dicke, 2 m Breite und 10 m Länge. Diese Abmessungen sind variabel. Teil I ist die eigentliche Schutzabdeckung.Part I is a 1-ply plastic film 50-200 my thick, 2 m wide and 10 m Length. These dimensions are variable. Part I is the actual protective cover.

Teil II ist das Funktionsteil. Es übernimmt Transport und Ballastierung. Es ist in seinen Abmessungen dem Teil I angepaßt. In der Längsrichtung ist es 20 cm schmaler als Teil I, so sind notwendige Überlappungen möglich. Das Funktionsteil ist aus 2 Kunststoffolien luft- und wasserdicht verschweißt und in 2 Rippensysteme unterteilt. Das breitere Rippensystem (ca. 20 cm breit) wird mit Druckluft gefüllt und dient dem Entrollen.Part II is the functional part. It takes care of transport and ballasting. It is in its dimensions adapted to Part I. In the longitudinal direction it is 20 cm narrower than part I, necessary overlaps are possible. The functional part is welded from 2 plastic films airtight and watertight and in 2 rib systems divided. The wider rib system (approx. 20 cm wide) is filled with compressed air and serves to unroll.

Das schmalere Rippensystem (ca. 5 cm breit) wird mit Wasser gefüllt und dient der Ballastierung. An der Einfüllseite ist je eine Öffnung zum Füllen mit Druckluft bzw. mit Wasser angeordnet. An den Enden einer jeden Rippe befindet sich eine weitere Öffnung, um Überdruck zu verhindern.The narrower rib system (approx. 5 cm wide) is filled with water and serves the Ballasting. On the filling side there is an opening for filling with compressed air or with Water arranged. There is another at the ends of each rib Opening to prevent overpressure.

Beide Teile ineinander aufgerollt bilden eine Einheit, wobei Teil I die untere Position einnimmt. Durch das Füllen mit Druckluft entsteht eine Druckluftwelle, die die Einheit entrollt.Both parts rolled up into each other form a unit, with part I the lower position occupies. Filling with compressed air creates a compressed air wave that forms the unit unrolled.

Parallel können die dafür vorgesehenen Rippen mit Wasser gefüllt werden. Dadurch erfolgt eine sofortige Beschwerung der Einheit und sie ist gegen Abheben gesichert. Die Einfüllseite wird so befestigt daß der Abrollvorgang nur in die gewünschte Richtung erfolgt. Werden mehrere Einheiten nebeneinander entrollt kann eine große Fläche geschützt werden.At the same time, the ribs provided can be filled with water. Thereby there is an immediate weighting of the unit and it is secured against lifting. The filler side is fastened so that the unrolling process only in the desired Direction. If several units are unrolled side by side, one can be large Area to be protected.

Bei sorgfältiger Behandlung kann das Teil II mehrmals eingesetzt werden.With careful handling, Part II can be used several times.

Erreichter Vorteil:
Der Schutz des Frischbetons kann nun zum günstigsten Zeitpunkt erfolgen.Achieved advantage:
The fresh concrete can now be protected at the most convenient time.

Neuartige durch Druckluftzuführung selbstentrollende Kunststoffolienabdeckung zum Schutz von Frischbeton- oder anderen Materialien, die erst nach dem trittfesten Erstarren begehbar sind.Novel plastic film cover self-rolling by compressed air supply for Protection of fresh concrete or other materials that only after the hard-wearing Freezes are walkable. Problem:
Nach der Din 1045 ist die sogenannte Nachbehandlung von Frischbeton zwingend vorgeschrieben, d. h. Frischbeton muß gegen Witterungseinflüsse geschützt werden. Stand der Technik Problem:
According to Din 1045, the so-called after-treatment of fresh concrete is mandatory, ie fresh concrete must be protected against the weather. State of the art Methode 1:
Nach dem trittfesten Erstarren des Frischbetons wird eine Kunststoffolie aufgezogen und gegen Abheben gesichert.Method 1:
After solidification of the fresh concrete, a plastic film is put on and secured against lifting. Methode 2:
Kontinuierliches Besprühen mit Wasser.Method 2:
Continuous spraying with water. Methode 3:
Mechanisches Abscheiben, d. h. routierende Metallscheiben verdichten die Oberfläche des bereits erstarrten Beton.Method 3:
Mechanical abrading, ie routing metal discs, compact the surface of the already solidified concrete. Methode 4:
Vakuumieren der Oberflächen, d. h. dem Frischbeton wird das Wasser entzogen.Method 4:
Vacuuming the surfaces, ie the water is extracted from the fresh concrete. Methode 5:
Es wird eine flüssige wachsähnliche Substanz aufgetragen. Sie ist aber nicht in jedem Fall einsetzbar, z. B. wenn ein weiterer Betonaufbau erfolgen soll.Method 5:
A liquid wax-like substance is applied. However, it cannot be used in every case, e.g. B. if another concrete structure is to take place. Alle Methoden setzen aber die Begehbarkeit des Betons voraus.However, all methods require the concrete to be walkable. Lösung:
Eine durch Druckluft betriebene, selbstentrollende 3 lagige Kunststoffolie, die auch gegen Abheben gesichert werden kann.Solution:
A self-rolling 3-layer plastic film operated by compressed air, which can also be secured against lifting.
