Abstract
Description
Die Erfindung betrifft ein Verfahren zur Feuchthaltung von Betonoberflächen zum Zwecke der Nachbehandlung sowie eine feuchtigkeitsspeichernde Schicht zur Durchführung des Verfahrens.The invention relates to a method for keeping concrete surfaces moist for the purpose of post-treatment as well as a moisture-storing layer to carry out the procedure.
Mit diesem Verfahren soll die notwendige Feuchthaltung der Betonoberfläche während der ersten Zeit nach dem Ausschalen oder Ausformen ermöglicht werden. Dadurch kann ein großer Teil der Korrosionsschäden an Stahlbetonbauten ver mieden werden.This process aims to keep the concrete surface moist during the first period after stripping or molding. As a result, a large part of the corrosion damage to reinforced concrete structures can ver be avoided.
Es sind weitere Verfahren bekannt, die diese Nachbehandlung der Betonober fläche gewährleisten (vgl. Richtlinie zur Nachbehandlung von Beton des Deutschen Ausschusses für Stahlbeton, Feb. 1984). Dazu gehören u. a.:There are other methods known for this post-treatment of the concrete surface Ensure surface (see guideline for post-treatment of concrete of the German Committee for Reinforced Concrete, Feb. 1984). These include a .:
1. das Belassen in der Schalung
2. das Abdecken mit Folien
3. das Aufspritzen filmbildender Nachbehandlungen
4. das kontinuierliche Besprühen mit Wasser
5. das Abdecken mit wasserhaltenden Matten.1. leaving in the formwork
2. covering with foils
3. the spraying of film-forming after-treatments
4. the continuous spraying with water
5. covering with water-holding mats.
Diese bekannten Verfahren weisen jeweils die folgenden Nachteile auf:These known methods each have the following disadvantages:
Zu 1: Die Schalung muß möglichst bald abgenommen werden, um an anderer Stelle wieder eingesetzt werden zu können oder um an dem bereits betonierten Teil anbauen zu können. To 1: The formwork must be removed as soon as possible, in order to be on other Place to be able to be used again or to be able to use the to be able to add a concrete part.
Zu 2: Das Abdecken mit Folien an senkrechten Flächen erfordert besondere Maßnahmen zur Befestigung und zum Verhüten der "Kaminwirkung" zwi schen Bauteil und Folie.Ad 2: Covering with foils on vertical surfaces requires special Measures to fix and prevent the "chimney effect" between component and film.
Zu 3: Filmbildende Nachbehandlungsmittel erfüllen ihren Zweck nur in den ersten Stunden nach dem Betonieren; später reicht ihre schützende Wirkung nicht mehr aus bzw. verhindern sie die Haftung nachträglich aufzubringender Beschichtungen (wie Farbanstriche).To 3: Film-forming aftertreatment agents only serve their purpose in the first hours after concreting; later their protective will suffice No longer have an effect or prevent liability subsequently coatings to be applied (such as paint coats).
Zu 4: Kontinuierliches Besprühen mit Wasser verbietet sich oft von selbst, wenn keine Möglichkeit besteht, überschüssiges Wasser schadlos abzu leiten, und erfordert einen beträchtlichen Aufwand an Arbeitszeit.Ad 4: Continuous spraying with water often prohibits itself, if there is no way to safely remove excess water direct, and requires a considerable amount of work.
Zu 5: Wasserhaltende Matten müssen immer wieder besprüht werden um nicht auszutrocknen, so daß sie praktisch nur in Verbindung mit o. g. Folienabdeckung verwendet werden.5: Water-retaining mats have to be sprayed again and again in order not to to dry out, so that they are practically only in connection with o. g. Foil cover can be used.
Der Erfindung liegt die Aufgabe zugrunde, auf wirksame und einfache Weise die Nachbehandlung der Oberflächen von Betonteilen jeglicher Form durchzuführen. Diese Aufgabe wird bei dem gattungsgemäßen Verfahren bzw. mit der gattungsge mäßen feuchtigkeitsspeichernden Schicht durch die kennzeichnenden Merkmale der Ansprüche 1 bzw. 5 gelöst. Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß durch das Aufspritzen der feuchtigkeitsspeichernden Schicht Betonteile jeglicher Form mit einem geringem Arbeitsaufwand vollflä chig nachbehandelt werden können. Zudem ist das Entfernen der aufgetragenen Schicht unproblematisch. Es werden auch keine Flecken auf dem Beton hinterlas sen.The invention has for its object the in an effective and simple manner Carry out post-treatment of the surfaces of concrete parts of any shape. This task is in the generic method or with the genus moderate moisture-storing layer due to the characteristic features of the Claims 1 and 5 solved. The advantages achieved with the invention exist especially in that by spraying the moisture-storing Layer of concrete parts of any shape with a small amount of work can be treated afterwards. In addition, the removal of the applied Layer unproblematic. No stains are left on the concrete sen.
Betonfertigteile können deshalb mit geringem Platzbedarf am Herstellungsort oder sogar noch während des Transportes einer Nachbehandlung unterzogen werden.Precast concrete can therefore take up little space at the manufacturing site or even subjected to post-treatment during transportation will.
Die Erfindung wird im folgenden anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert. The invention is described below with reference to one in the drawing Embodiment explained in more detail.
Es zeigt:It shows:
Fig. 1 den schematischen Schnitt durch ein Betonbauteil, das mit einer erfin dungsgemäßen feuchtigkeitsspeichernden Schicht versehen ist; Fig. 1 is a schematic section through a concrete component, which is provided with a moisture-retaining layer OF INVENTION to the invention;
Fig. 2 eine Detailvergrößerung der feuchtigkeitspeichernden Schicht. Fig. 2 shows an enlarged detail of the moisture-storing layer.
Der schematische Schnitt durch das Betonbauteil 3 in Fig. 1 zeigt die auf der Betonoberfläche 2 aufgebrachte feuchtigkeitsspeichernde Schicht 1. In diesem Ausführungsbeispiel sind elektrische Heizelemente 4 in Form einer Matte mittig in der feuchtigkeitsspeichernden Schicht 1 angeordnet.The schematic section through the concrete component 3 in FIG. 1 shows the moisture-storing layer 1 applied to the concrete surface 2 . In this exemplary embodiment, electrical heating elements 4 in the form of a mat are arranged centrally in the moisture-storing layer 1 .
Nicht dargestellt ist die Anwendung von Heizröhren 5 anstatt der elektrischen Heizelemente 4. Beide dienen dazu, das Einfrieren der Flüssigkeit 7 in der feuchtigkeitspeichernden Schicht 1 zu verhindern.The use of heating tubes 5 instead of the electrical heating elements 4 is not shown. Both serve to prevent the freezing of the liquid 7 in the moisture-storing layer 1 .
Die Detailvergrößerung in Fig. 2 zeigt, daß die aufgespritzte feuchtigkeits speichernde Schicht 1 aus einem Flüssigkeit 7 enthaltendem Fasermaterial 6 be steht. Bei Anwendung von Fasermaterial aus Altpapier wird dieses durch die Flüssigkeit 7 aufgeweicht und bildet eine selbsthaftende Schicht 1. Diese kann auch unproblematisch an vertikalen Flächen angebracht werden.The enlargement in detail in Fig. 2 shows that the sprayed moisture-storing layer 1 is made of a liquid 7 containing fiber material 6 be. When using fiber material made from waste paper, it is softened by the liquid 7 and forms a self-adhesive layer 1 . This can also be easily attached to vertical surfaces.
