Description
Armierungsteile, Einbauteile oder Schalungshilfsmittel für StahlbetonkonstruktionenReinforcing parts, built-in parts or formwork aids for reinforced concrete structures
Die Erfindung betrifft Armierungsteile, Einbauteile oder Schalungshilfsmittel für Stahlbetonkonstruktionen, die mit dem Beton wasserführende Spalte bilden können, so daß eine Abdichtung gegen an einer Außenfläche der Betonkonstruktion anstehendes, drückendes Wasser nicht gewährleistet ist.The invention relates to reinforcement parts, built-in parts or formwork aids for reinforced concrete structures, which can form water-bearing gaps with the concrete, so that sealing against pressing water on an outer surface of the concrete structure is not guaranteed.
Der Erfindung liegt die Aufgabe zugrunde, die Armierungsteile, Einbauteile oder Schalungshilfsmittel so zu gestalten, daß sie nach der Einbettung in eine Betonschicht Haarrisse oder Spalte gegenüber dem Beton bei einer Wasserbeaufschlagung sicher abdichten.The invention is based on the object of designing the reinforcement parts, built-in parts or formwork aids in such a way that, after being embedded in a concrete layer, they reliably seal hairline cracks or gaps against the concrete when exposed to water.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Armierungsteile, Einbauteile oder Schalungshilfsmittel eine vollständige oder partielle Beschichtung mit einem unter Wasserbeaufschlagung quellfähigen Material aufweisen.This object is achieved according to the invention in that the reinforcement parts, built-in parts or formwork aids have a complete or partial coating with a material that swells when exposed to water.
Sofern das quellfähige Material nach der Einbettung der Armierungsteile, der Einbauteile oder Schalungshilfsmittel in eine Betonschicht mit drückendem Wasser inIf the swellable material is exposed to pressurized water after the reinforcement parts, built-in parts or formwork aids have been embedded in a concrete layer,

Berührung kommt quillt das Material auf und verschließt im Zuge der Volumenvergrößerung die Haarrisse, Spalte o.dgl., so daß sich eine einwandfreie Abdichtung ergibt.When it comes into contact, the material swells and, as the volume increases, closes the hairline cracks, gaps, etc., so that a perfect seal is created.
Die Armierungsteile, die Einbauteile oder Schalungshilfsmittel, die in der Betonschicht angeordnet sind, können die unterschiedlichsten geometrischen Formen aufweisen.The reinforcement parts, built-in parts or formwork aids arranged in the concrete layer can have a wide variety of geometric shapes.
Einige dieser Bauteile, die vollständig oder partiell mit einem quellfähigen Material beschichtet sind, sind in der Zeichnung dargestellt und werden im folgenden beschrieben. Some of these components, which are completely or partially coated with a swellable material, are shown in the drawing and are described below.

Diese Beschichtung 2 kann aus einem quellfähigen Kunststoff oder Gummimaterial bestehen.This coating 2 can consist of a swellable plastic or rubber material.
Die Beschichtung kann durch Streichauftrag, Tauchen, Sprühen oder Klebung erfolgen. The coating can be applied by brushing, dipping, spraying or gluing.
Sofern der Beton 3 nicht ausreichend verdichtet wird und nicht spaltfrei an den eingebetteten Bewehrungs- und Ankerteilen sowie an Einbauteilen oder Schalungshilfsmitteln anliegt, kann an einer Betonseite anstehendes, drückendes Wasser durch die Spalträume 4, 5, die von dem eingebetteten Metallteil und dem Beton begrenzt werden, strömen, so daß die Wasserdichtigkeit des Stahlbetonteils nicht mehr gegeben ist.If the concrete 3 is not sufficiently compacted and does not lie gap-free against the embedded reinforcement and anchor parts as well as against built-in parts or formwork aids, water under pressure on one side of the concrete can flow through the gaps 4, 5, which are delimited by the embedded metal part and the concrete, so that the watertightness of the reinforced concrete part is no longer ensured.
Die in den Beton eingebetteten Armierungsteile, Einbauteile oder Schalungshilfsmittel sind mit einer quellfähigen Beschichtung 2 versehen, die mit dem WasserThe reinforcement parts, built-in parts or formwork aids embedded in the concrete are provided with a swellable coating 2, which swells with the water

gewährleistet.
20reacts and, as shown in the lower half of Figure 7, fills the hairline cracks, gaps, etc. through an increase in volume. The watertightness of the reinforced concrete part is thus ensured by the swellable coating 2 which reacts with the water.

Die in dem Beton eingebetteten Teile können auch eine plattenförmige Wassersperre 6, die mit dem Ankerstab 1 verbunden ist, sein. Auch diese Platte wird mit einer quellfähigen Beschichtung versehen.The parts embedded in the concrete can also be a plate-shaped water barrier 6, which is connected to the anchor rod 1. This plate is also provided with a swellable coating.
Auch die in den Figuren 3, 4 und 5 dargestellte Fugenblechklammer 7, durch die die sich überlappenden Enden zweier Fugenbleche 8 und 9 festgelegt wird, kann ebenfalls wie die Fugenbleche mit einer quellfähigen Beschichtung ausgerüstet sein.The joint sheet clamp 7 shown in Figures 3, 4 and 5, by which the overlapping ends of two joint sheets 8 and 9 are fixed, can also be equipped with a swellable coating like the joint sheets.
