Abstract
Description
Die Erfindung betrifft einen Betonabstandhalter mit Mittelloch und hindurchgestecktem Befestigungsdraht.The invention relates to a concrete spacer Center hole and a fastening wire inserted through it.
Im Betonstahlbau werden in großem Umfang zwischen den Stahlbewehrungen und der Schalung Betonabstandhalter eingebracht, bevor die weiche Betonmasse eingestürzt wird, damit zwischen der Stahlbewehrung und der nach dem Aushärten des Betons abzunehmenden Schalung eine durchgehende Beton schicht entsteht und aushärtet.In reinforcing steel construction, there are large differences between the Steel reinforcements and formwork concrete spacers brought in before the soft concrete mass collapses, between the steel reinforcement and after hardening the formwork to be removed is a continuous concrete layer arises and hardens.
Es gibt Betonabstandhalter mit einem Mittelloch und einem hindurchgesteckten Befestigungsdraht, die mit den Befesti gungsdrahtenden an der Betonbewehrung befestigt werden, bevor der weiche Beton eingestürzt wird.There are concrete spacers with a center hole and one Fastening wire inserted through it with the fastening the wire ends are attached to the concrete reinforcement, before the soft concrete collapses.
Ein Nachteil dieser Betonabstandhalter besteht darin, daß die Schaffung dieses Mittellochs und seine Offenhaltung einen erheblichen Aufwand erfordern.A disadvantage of these concrete spacers is that the creation of this center hole and its keeping open require considerable effort.
Der Erfindung liegt die Aufgabe zugrunde, die Schaffung und Offenhaltung eines solchen Mittellochs in einem Betonabstand halter mit einfachsten Mitteln zu gewährleisten, die nicht nur das Einschieben des Befestigungsdraht erleichtern, sondern auch zu einer Gewichtsverminderung des Betonabstandhalters führen. The invention has for its object to create and Keeping such a center hole open at a concrete distance to ensure holders with the simplest of means that are not only facilitate the insertion of the fastening wire, but also to reduce the weight of the concrete spacer to lead.
Gelöst wird diese Aufgabe nach der Erfindung dadurch, daß das Mittelloch eine Auskleidung in Form einer Hülse aus Kunststoff, Metall, Kartonagewerkstoff oder Naturwerk stoffen (Stroh u.ä.) aufweist.This object is achieved according to the invention by that the center hole is a liner in the form of a sleeve made of plastic, metal, cardboard material or natural work substances (straw, etc.).
Zweckmäßigerweise ist die Hülse auf ihrer Außenseite mit Vorsprüngen und Fortsätzen versehen, die in den Betonwerk stoff des Betonabstandhalters eingreifen.Appropriately, the sleeve is on the outside with Protrusions and extensions provided in the concrete plant Intervene in the material of the concrete spacer.
Die beschriebenen Hülsen haben den Vorteil, daß das Mittel loch bei der Herstellung des Betonabstandhalters, aber auch beim Einfädeln des Befestigungsdrahtes, einwandfrei und gesichert offengehalten wird.The sleeves described have the advantage that the agent hole in the manufacture of the concrete spacer, but also when threading the fastening wire, perfect and is securely kept open.
