Abstract

The invention relates to supporting elements for forming foundation bodies, for example large-diameter bored piles, piles produced with a shell auger or vibrated concrete columns which are constructed with fibre concrete.

Description

Die Erfindung betrifft Tragelemente zur Bildung von Gründungs­ körpern. Bei der Herstellung von Pfählen werden entweder be­ wehrte oder unbewehrte Pfähle nach verschiedenen Verfahren im Boden hergestellt. Bei den bewehrten Pfählen wird dazu ein Be­ wehrungskorb vor dem Betoneinbau in die Bohrung gestellt. Aus dem Einsatz ist bekannt, daß beim Betonieren Verdrehungen oder Setzungen des Korbes auftreten können.The invention relates to support elements for the formation of foundation bodies. In the manufacture of piles, either Reinforced or unreinforced piles using various methods in the Floor made. For the reinforced piles, a Be reinforcement cage placed in the hole before the concrete is installed. Out the use is known that when concreting twists or Settlement of the basket can occur.

Stahlfaserbeton bietet verschiedene Vorteile:Steel fiber concrete offers several advantages:

Die Biegezugfestigkeit des Betons wird erhöht, ebenso wie die Betondruckfestigkeit, Schwindrisse werden vermieden, die Was­ serdichtigkeit wird verbessert, Arbeitsgang "Bewehrungseinbau" entfällt. Aus dem Bereich des Tunnel- und Stollenbaus sind An­ wendungen des Faserbetons als Stahlfaserbeton - auch als Spritzbeton - bekannt.The bending tensile strength of the concrete is increased, as is the concrete compressive strength, shrinkage cracks are avoided, the water tightness is improved, the "reinforcement installation" step is omitted. From the field of tunnel and tunnel construction, applications of fiber concrete as steel fiber concrete - also known as shotcrete - are known.

Mit diesen Vorteilen lassen sich die faserbewehrten Tragelemen­ te herstellen. Zur Herstellung bewehrter Pfähle mit Hohlbohr­ schnecken sind Schnecken mit großem Rohrdurchmesser erforder­ lich; z.B. da/di=70/40 cm. Wird die Bewehrung durch Stahlfa­ sern ersetzt, kann ein kleineres Rohr bei gleichem Außendurch­ messer verwendet werden. Dadurch erfolgt ein schnelleres Ein­ treiben der Hohlbohrschnecke und der Pfahl ist über den Gesamt­ querschnitt bewehrt. The fiber-reinforced support elements can be used with these advantages manufacture. For the production of reinforced piles with hollow drilling screws with a large pipe diameter are required Lich; e.g. da / di = 70/40 cm. If the reinforcement by Stahlfa a smaller pipe with the same outside diameter knives are used. This results in a faster on drive the hollow auger and the pile is over the whole cross-section reinforced.  

Ein weiteres Anwendungsgebiet liegt bei den Betonrüttelsäulen. Durch Faserbewehrung kann die Druckfestigkeit gegenüber unbe­ wehrtem Beton um 15% gesteigert werden. Bei Anwendung für in der Regel unbewehrte Betonrüttelsäulen im Boden kann somit ent­ weder der Säulendurchmesser oder die Anzahl der Säulen redu­ ziert werden.Another area of application is in the concrete vibrating columns. With fiber reinforcement, the compressive strength can be reduced reinforced concrete can be increased by 15%. When used for unreinforced concrete vibrating columns in the ground can thus be removed neither the column diameter or the number of columns redu be decorated.

Der Einbau des Faserbetons erfolgt mit den aus dem Stand der Technik bekannten Verfahren.The installation of the fiber concrete takes place with the from the state of the Technique known.
