Korrosionsschutzmasse für Stahlbewehrungen in Halbrahmen-Tragkonstruktionen von Kleinbauwerken
Die Erfindung betrifft eine auf Zementbasis hergestellte Korrosionsschutzmasse, mit der vorzugsweise die Bewehrungseinlagen von Halbrahmen-Tragkonstruktionen ummantelt werden, welche als Fertigteile hergestellt und für die Errichtung von Kleinbauwerken, wie Bungalows, Kioske, Kleingaragen u. dgl. in Montagebauweise Verwendung finden.
Solche an sich bekannten Fertigteile werden nach einer andern Erfindung aus einer Baustoffmischung hergestellt, die aus nichthydraulischen Baustoffbindern, basischer Hochofenschlacke, HarnstoffFormaldehydharz und/oder Polyvinylacetat-Dispersion besteht. Diese Baustoffmischung macht die Fertigteile in sehr hohem Masse widerstandsfähig gegenüber den wechselnden Klima- und Witterungseinflüssen.
Um die Bewehrungseinlagen noch zusätzlich gegen Korrosion zu schützen, müssen sie einen dementsprechend wirksamen Überzug erhalten. Es sind solche Überzüge bekannt, die aus Lösungen aus Polyvinylacetat und Eisen-III-Chlorid bestehen. Solche Korrosionsschutzüberzüge führten bei Baustoffmischungen auf der Basis von kunstharzvergüteten, nichthydraulischen Baustoffbindern nicht zu dem angestrebten Ergebnis und erhöhten auch in unerwünschtem Masse den Aufwand für die Herstellung der Fertigteile insgesamt.
Die Aufgabe der Erfindung wurde deshalb darin gesehen, die Vorzüge der nach einer'andern Erfindung geschützten Baustoffmischung auf der Basis von nichthydraulischen Baustoffbindem auszunutzen und die Komponenten der Korrosionsschutzmasse so auf die Komponenten der Baustoffmischung abzustimmen, dass eine sich harmonisch ergänzende und gesteigerte Korrosionsschutzmischung für die Bewehrungseinlagen eintritt.
Erfindungsgemäss wird nun vorgeschlagen, dass die Masse aus folgenden Bestandteilen angerührt ist :
20,0 Gel.-% Hochofenzement
EMI1.1
<Desc/Clms Page number 2>
Durch mehrmaliges Tauchen der Bewehrungskörper in die wässerige Lösung wird eine zwei Millimeter dicke Ummantelung der Bewehrungseinlagen erzielt.
Vorteilhafterweise wird der nach dem ersten Tauchen erzielte Überzug bei einer Temperatur von +60 C getrocknet und durch Wiederholung des Tauchbades ein 2 mm dicker Korrosionsschutzmantel auf der Bewehrung erzielt. Mit diesem Korrosionsschutz versehen, werden die Bewehrungskörper in die zur Herstellung der Halbrahmen-Tragkonstruktion bestimmten Formen eingelegt und die Form mit der Baustoffmischung gefüllt.

Corrosion protection compound for steel reinforcement in half-frame supporting structures of small buildings
The invention relates to a cement-based anti-corrosion compound with which the reinforcement layers are preferably encased by half-frame supporting structures, which are manufactured as prefabricated parts and are used for the construction of small structures such as bungalows, kiosks, small garages and the like. Like. Find use in assembly construction.
Such prefabricated parts, known per se, are produced according to another invention from a building material mixture which consists of non-hydraulic building material binders, basic blast furnace slag, urea-formaldehyde resin and / or polyvinyl acetate dispersion. This mix of building materials makes the prefabricated parts highly resistant to changing climatic and weather influences.
In order to additionally protect the reinforcement inserts against corrosion, they must be given a correspondingly effective coating. Such coatings are known which consist of solutions of polyvinyl acetate and ferric chloride. In the case of building material mixtures based on synthetic resin-modified, non-hydraulic building material binders, such anti-corrosive coatings did not lead to the desired result and also increased the expenditure for the production of the finished parts to an undesirable extent.
The object of the invention was therefore seen in exploiting the advantages of the building material mixture protected according to another invention on the basis of non-hydraulic building material binders and coordinating the components of the corrosion protection compound with the components of the building material mixture in such a way that a harmoniously complementary and increased corrosion protection mixture for the reinforcement layers entry.
According to the invention it is now proposed that the mass is made up of the following components:
20.0 gel% blast furnace cement
EMI1.1
<Desc / Clms Page number 2>
By dipping the reinforcement bodies several times in the aqueous solution, the reinforcement inserts are sheathed two millimeters thick.
The coating obtained after the first immersion is advantageously dried at a temperature of +60 ° C. and a 2 mm thick corrosion protection coat is obtained on the reinforcement by repeating the immersion bath. Provided with this corrosion protection, the reinforcement bodies are placed in the molds intended for the production of the half-frame support structure and the mold is filled with the building material mixture.
