Abstract

Es handelt sich um ein Verfahren zur Erstellung eines rückbaubaren Verpreßankers mit einem Verpreßkörper (3) und einem oder mehreren angeschlossenen Zuggliedern (4). Dabei wird zusammen mit dem zumindest einen Zugglied (4) ein Aufbrechkörper (7) und ein daran mit Dichtwirkung anliegendes aufstehendes Hüllrohr (8) mit darin bewegbarem Aufbrechzugglied (9) in den Verpreßkörper (3) eingebracht und der Aufbrechkörper (7) und teilweise das Hüllrohr (8) von dem Verpreßkörper (3) umschlossen. Nach Gebrauchsende des Verpreßankers wird der Aufbrechkörper (7) mittels des Aufbrechzuggliedes (9) unter Aufbrechen des Verpreßkörpers (3) und Lösen der Haftverbindung zwischen Zugglied (4) und Verpreßkörper (3) durch das Hüllrohr (8) aus dem Verpreßkörper (3) herausgezogen.

It is a method for creating a removable anchor with a compression body (3) and one or more connected tension members (4). Together with the at least one tension member (4), a rupture body (7) and an upstanding cladding tube (8) resting thereon with a sealing effect, with a rupture tension member (9) movable therein, are introduced into the compression body (3) and the rupture body (7) and partially that Cladding tube (8) enclosed by the compression body (3). After the end of use of the compression anchor, the break-open body (7) is pulled out of the compression body (3) by means of the break-up tension member (9), breaking up the compression body (3) and releasing the adhesive connection between tension member (4) and compression body (3) through the cladding tube (8) .
