Abstract

In hitherto customary methods, the steel surface sections have been provided with a corrosion-protection lacquer. This method had, under unfavourable conditions, e.g. with moist lightweight concrete, unsatisfactory results, especially with regard to the durability of the lacquer. To obtain permanent, satisfactory corrosion protection in steel surface sections of reinforced lightweight concrete elements, a shaped part (4) consisting of a sleeve which is closed on one side and is preferably made from a special steel, is pushed over the reinforcing-steel end (3) into the lightweight concrete element (5). As a result, a smooth-faced outer surface, on which the adhesion of a subsequent coat of paint, a coating (6) or the like is guaranteed, is obtained. <IMAGE>

Description

Die Erfindung betrifft ein Verfahren zum Korrosionsschutz von Stahl-Schnittflächen von bewehrten Gasbeton-Bauteilen und eine Vorrichtung zur Durchführung des Verfahrens, die einen dauerhaften Korrosionsschutz an Stahl-Schnittflächen von bewehrten Gasbeton-Bauteilen mit Hilfe eines Formteiles ermöglicht.The invention relates to a method for corrosion protection of steel cut surfaces of reinforced gas concrete components and a device for carrying out the method, which enables permanent corrosion protection of steel cut surfaces of reinforced gas concrete components with the aid of a molded part.

Es ist bekannt, daß bei der Herstellung von Gasbeton-Platten diese werkseitig geschnitten werden können. Dies wird z.B. in den amtlichen Zulassungen zitiert, in denen es sinngemäß heißt: Die Platten dürfen in Ausnahmefällen nachträglich durch Beauftragte des Herstellwerks gekürzt werden, wenn dadurch die Plattentragfähigkeit, insbesondere die Endverankerung gemäß DIN 4223 (Ausgabe 7/58) Abschnitt 9.52 nicht beeinträchtigt wird. Ein solcher Arbeitsgang darf nur mittels Trennscheiben durchgeführt werden. Die Schnittflächen von Stählen sind mit einem Korrosionsschutz zu versehen.It is known that when manufacturing gas concrete slabs, these can be cut at the factory. This is e.g. cited in the official approvals, in which it is analogously stated: In exceptional cases, the panels may subsequently be shortened by representatives of the manufacturing plant if the panel load-bearing capacity, in particular the end anchorage in accordance with DIN 4223 (edition 7/58) section 9.52 is not impaired. Such an operation may only be carried out using cutting discs. The cut surfaces of steels must be provided with corrosion protection.

Die gängigsten Methoden, diesen Korrosionsschutz zu gewährleisten, sind weltweit bei den meisten Gasbeton-Herstellern:

  • 1. das Aufbringen eines Korrosionsschutz-Lackes auf die Stahl-Schnittflächen,
  • 2. das Hinterschneiden des Stahles mittels einer Trennscheibe, anschließendes Aufbringen eines Korrosionsschutz-Lackes und als dritten Arbeitsgang das Vermörteln der Vertiefung.
The most common methods of ensuring this corrosion protection are at most gas concrete manufacturers worldwide:
  • 1. the application of a corrosion protection lacquer on the steel cut surfaces,
  • 2. the undercut of the steel by means of a cutting disc, subsequent application of an anti-corrosion lacquer and, as a third step, the grouting of the recess.

Die erste Methode hat folgende Nachteile:

  • a) bei feuchtem Gasbeton hält der Lack nicht,
  • b) ein zufriedenstellender Korrosionsschutz ist nur durch zweimaligen Lack-Auftrag gewährleistet,
  • c) dadurch zeitintensiv durch einzuhaltende Trocknungszeiten,
  • c) empfindlich bei Frost-Tau-Wechsel,
  • d) bei nachträglicher Durchfeuchtung kann der Rost durch die Gasbeton-Beschichtung diffundieren und Verfärbungen an der Oberfläche hervorrufen.
The first method has the following disadvantages:
  • a) the paint does not hold when the gas concrete is moist,
  • b) satisfactory corrosion protection is only guaranteed by applying two coats of paint,
  • c) time-consuming due to drying times to be observed,
  • c) sensitive to freeze-thaw changes,
  • d) if moistened afterwards, the rust can diffuse through the gas concrete coating and cause discoloration on the surface.

Sie hat jedoch den Vorteil, daß sie sehr kostengünstig ist.However, it has the advantage that it is very inexpensive.

Die zweite Methode hat folgende Nachteile:

  • a) sehr kostenintensiv,
  • b) sehr zeitintensiv, da drei Arbeitsgänge mit Trocknungszeit erforderlich sind,
  • c) erhöhter maschineller Aufwand, da eine Trennscheibe mit Absaugung notwendig ist.
The second method has the following disadvantages:
  • a) very expensive,
  • b) very time-consuming, since three work steps with drying time are required,
  • c) increased mechanical effort, since a cutting disc with suction is necessary.

Sie garantiert jedoch einen dauerhaften, einwandfreien Korrosionsschutz selbst unter widrigen Umständen.However, it guarantees permanent, flawless corrosion protection even under adverse conditions.

Aufgabe der vorliegenden Erfindung ist es, die genannten Vorteile der herkömmlichen Methoden durch ein völlig neuartiges Verfahren zu erzielen oder sogar zu übertreffen, ohne die begleitenden Nachteile der herkömmlichen Methoden in Kauf nehmen zu müssen. Diese Aufgabe wird durch die in den Patentansprüchen angegebenen Merkmale gelöst.The object of the present invention is to achieve or even exceed the advantages of the conventional methods mentioned by means of a completely new method, without having to accept the accompanying disadvantages of the conventional methods. This object is achieved by the features specified in the patent claims.

Die Brauchbarkeit des erfindungsgemäßen Verfahrens ist durch zahlreiche Versuche belegt. Dazu wurden folgende Hülsen verwendet:
Es wurde ein Tiefziehteil aus einer zylindrisch-glatten Blechhülse - einseitig geschlossen - hergestellt. Das Material bestand aus ST 4301, mit folgenden Durchmessern: Durchmesser = 15 mm, Länge = 15 mm, Wanddicke = 0,27 mm.The usefulness of the method according to the invention has been proven by numerous tests. The following sleeves were used:
A deep-drawn part was produced from a cylindrical, smooth sheet metal sleeve - closed on one side. The material consisted of ST 4301, with the following diameters: diameter = 15 mm, length = 15 mm, wall thickness = 0.27 mm.

Es wurde eine Wandplatte A mit offenliegenden Stahlschnittflächen und eine erfindungsgemäß korrosionsgeschützte Wandplatte B einem Bewitterungsversuch im Freien ausgesetzt. Nach einem Jahr zeigte sich, daß die Wandplatte A an den Stahlschnittflächen starke Korrosionserscheinungen aufwies, während die erfindungsgemäße Wandplatte B ohne jedes Anzeichen von Korrosion blieb.A wall plate A with exposed steel cut surfaces and a wall plate B which was protected against corrosion according to the invention were subjected to an outdoor weathering test. After a year, it was found that wall plate A had strong signs of corrosion on the steel cut surfaces, while wall plate B according to the invention remained without any signs of corrosion.

Weitere Korrosionsversuche unter verschärften Bedingungen wurden in einem 3 %igen Salzbad durchgeführt. Am Plattenabschnitt C wurden die Stahlschnittflächen mit einem Acryllack betupft, am Plattenabschnitt B wurden die Stahlschnittflächen mittels der erfindungsgemäßen Hülsen verschlossen und dann mit einer Beschichtung aus einer Kunstharzdispersion versehen. Nach einer Versuchsdauer von 2 Tagen zeigte sich an der Platte C Rostansatz, während am Plattenabschnitt D auch nach Entfernung der Hülsen keine Rostansätze zu erkennen waren.Further corrosion tests under more stringent conditions were carried out in a 3% salt bath. At the plate section C, the steel cut surfaces were dabbed with an acrylic lacquer, at the plate section B the steel cut surfaces were closed by means of the sleeves according to the invention and then provided with a coating of a synthetic resin dispersion. After a test period of 2 days, rust formation appeared on plate C, while no rust formation was evident on plate section D even after the sleeves had been removed.

In weiteren Versuchen wurde festgestellt, daß die Beschichtung unter folgenden Bedingungen besonders korrosionsschützend wirkt: Auftragsmenge mindestens 1800 g/m² in zwei Lagen, wobei die erste Lage mit ca. 20 % und die zweite Lage mit max. 5 % verdünnt wird. Bei der Trocknung dürfen Temperaturen von + 5° nicht unterschritten werden. Unter diesen Bedingungen zeigte sich, daß auch einjährigem verschärftem Korrosionstest kein Abplatzen und keine Korrosionserscheinungen festgestellt werden konnten. Das erfindungsgemäß hergestellte korrosionsgeschützte Gasbetonbauteil kann mit einem späteren Farbanstrich versehen werden, wobei eine glattflächige äußere Oberfläche erzielt wird.In further tests, it was found that the coating had a particularly protective effect against corrosion under the following conditions: application amount at least 1800 g / m 2 in two layers, the first layer with approx. 20% and the second layer with max. Is diluted 5%. When drying, temperatures must not fall below + 5 °. Under these conditions, it was found that even a one-year tightened corrosion test showed no flaking and no signs of corrosion. The corrosion-protected aerated concrete component produced according to the invention can be provided with a later coat of paint, a smooth outer surface being achieved.

Als Material für die erfindungsgemäße Hülse wird Edelstahl bevorzugt angewandt, weil die Steifigkeit bei geringer Materialdicke besonders groß ist. Die geringe Materialdicke ist erforderlich, um nach der Gasbetonbeschichtung auch kleinste Unebenheiten auf der Oberfläche zu vermeiden.Stainless steel is preferably used as the material for the sleeve according to the invention, because the rigidity with a small material thickness is particularly large. The low material thickness is necessary in order to avoid even the smallest unevenness on the surface after the gas concrete coating.

Die Hülsenabmessungen wurden erfindungsgemäß so festgelegt, daß eine feste Verankerung im Gasbeton auch bei außen glatter Oberfläche der Hülse gesichert ist. Bei kurzen Hülsen besteht die Gefahr, daß die Mindesteindringtiefe für eine feste Verankerung nicht gewährleistet ist, während bei längeren Hülsen schon der erste Bewehrungsquerstab einer Bewehrungsmatte von der Hülse getroffen werden kann. Dann ist kein sauberes Eindrücken mehr möglich, sondern es kommt zu Verquetschungen und Erhebungen auf der Schnittoberfläche.The sleeve dimensions were determined in accordance with the invention in such a way that firm anchoring in the gas concrete is ensured even with a smooth outer surface of the sleeve. With short sleeves there is a risk that the minimum penetration depth is not guaranteed for firm anchoring, while with longer sleeves the first reinforcement crossbar of a reinforcement mat can be hit by the sleeve. Then it is no longer possible to press in cleanly, but there are squashes and bumps on the cutting surface.

Die Grenzen für den Hülsendurchmesser sind dadurch festgelegt, daß einerseits ein einwandfreies Gleiten über die Bewehrungsstähle im Gasbeton ermöglicht werden muß und andererseits kein Verkanten durch zu großes Spiel auf dem Bewehrungsstahl erfolgt. Bei Hülsendurchmessern über 50 mm besteht die Gefahr, daß beim Eindrücken die Hülse über das Gasbetonbauteil herausragt und dessen Kante beschädigt.The limits for the sleeve diameter are determined by the fact that, on the one hand, it must be possible to glide smoothly over the reinforcing steel in the gas concrete and, on the other hand, there is no tilting due to excessive play on the reinforcing steel. With sleeve diameters over 50 mm there is a risk that when pressed in the sleeve protrudes over the gas concrete component and damages its edge.

Die Wandstärke der Hülse sollte möglichst gering sein, um keine auffälligen Erhebungen auf der Gasbetonbeschichtung zu erhalten. Als besonders vorteilhaft haben sich folgende Abmessungen der Hülse erwiesen: Wanddicke 0,27 mm, Hülsendurchmesser 15 mm, Hülsenlänge 10 mm.The wall thickness of the sleeve should be as small as possible so that no noticeable elevations are obtained on the gas concrete coating. The following dimensions of the sleeve have proven to be particularly advantageous: wall thickness 0.27 mm, sleeve diameter 15 mm, sleeve length 10 mm.

Auch die Haftung eines späteren Farbanstriches, Beschichtung oder Putzes auf der erfindungsgemäß behandelten Schnittflächen-Oberfläche ist gewährleistet, wie ebenfalls durch Versuche belegt ist.The adhesion of a later coat of paint, coating or plaster to the surface of the cut surface treated according to the invention is also ensured, as is also proven by tests.

Die Erfindung ist in den Zeichnungen dargestellt.The invention is shown in the drawings.

In Fig. 1 ist die Gasbeton-Schnittfläche mit 1, die Bewehrung mit 2 und die Bewehrungs-Schnittfläche mit 3 bezeichnet. Das aus einer Hülse bestehende Formteil 4 ist über die Bewehrungs-Schnittfläche 3 in das Gasbeton-Bauteil eingedrückt.In Fig. 1, the gas concrete section is denoted by 1, the reinforcement by 2 and the reinforcement section by 3. The molded part 4 consisting of a sleeve is pressed into the gas concrete component via the reinforcement cut surface 3.

Die Fig. 2 zeigt die in das Gasbeton-Bauteil 5 eingebrachte Bewehrung 2, über die das Formteil 4 gedrückt ist. Die auf die Oberfläche aufgebrachte Beschichtung ist mit 6 beziffert. Der vor dem Eindrücken der Hülse 4 auf die Bewehrungs-Schnittfläche 3 aufgetragene Korrosionsschutz-Lack trägt das Bezugszeichen 7.2 shows the reinforcement 2 introduced into the gas concrete component 5, over which the molded part 4 is pressed. The coating applied to the surface is numbered 6. The corrosion protection lacquer applied to the reinforcement cut surface 3 before the sleeve 4 is pressed in has the reference number 7.
