Abstract

Spacer for rock anchor comprises a pear-shaped basket-like hard PVC body with tubular end sections. The spacer is mfd. by stamping out sections of equal length at corresp. intervals around the circumference of a hard PVC tube of given length. The tube is then subjected to pressure in the longitudinal direction to bend the punched strips outwards so as to form a pear-shaped basket-like body, and subjected to heating to 120 degrees for a short period. The spacer is suitable for anchoring ferrous wires, etc. which are subject to tension, so that on injection of cement at the anchoring point there is enough room for the cement to be hardened, to allow good anchoring.

Description

Abstandhalter für Bodenverankerungen und VerfahrenSpacers for ground anchoring and procedures

zur Herstellung derselben.to manufacture the same.

Die Erfindung bezieht sich auf einen vorzugsweise aus Hart-PVC bestehenden Abstandhalter für die Verankerung von auf Zug beanspruchten Eisendrähhen oder dergleichen, um zu erreichen, daß bei der Injektion von Zementtreufe an der Verankerungsstelle genügend Platz für den zu erhärtenden Zement frei gehalten wird, um eine gute Verankerung zu gewährleisten.The invention relates to a preferably made of rigid PVC Spacers for anchoring iron wires or the like that are subject to tensile stress, to achieve that when injecting cement struts at the anchorage point enough space is kept free for the cement to be hardened to ensure good anchoring to ensure.

Der erfindungsgemäße Abstandhalter ist gekennzeichnet durch einen annähernd birnenförmigen, korbartigen Körper mit rohrförmigen Endstücken.The spacer according to the invention is characterized by a approximately pear-shaped, basket-like body with tubular end pieces.

Das Verfahren zur Herstellung solcher Abstandhalter ist dadurch gekennzeichnet, daß ein vorzugsweise aus Hart-PVC bestehender Rohrabschnitt bestimmter Länge um seinen -Umfang in übereinstimmenden Abständen gleichlange Standschnitte erhält, wonach dieser Rohrabschnitt zur Bildung eines birnenförmigen, korbartigen Körpers in Richtung seiner Längsachse zum Herausbiegen der eingestanzten Streifen einem Preßdruck unterworfen und für kurze Zeit einer Erhitzung auf ca. 1200 ausgesetzt wird.The method for producing such spacers is characterized by that a pipe section, preferably made of rigid PVC, is of a certain length its circumference is given equal-length stand sections at the same intervals, after which this pipe section to form a pear-shaped, basket-like body in the direction of its longitudinal axis for bending out the punched strips Subjected to pressure and heated to approx. 1200 for a short time will.

In der Zeichnung ist der Erfindungsgegenstand beispielsweise dargestellt. Es zeigt Fig. 1 den Rohrabschnitt, Fig. la den mit gleichlangen Stanzschnitten versehenen Rohrabschnitt, Fig. Ib den durch Preßdruck und Erhitzung erzielten birnenförmigen, korbartigen Rohrabschnitt und Fig. Ic eine Draufsicht hierzu in der Pfeilrichtung A.In the drawing, the subject matter of the invention is shown, for example. It shows Fig. 1 the pipe section, Fig. La the punched cuts of the same length Pipe section, Fig. Ib the pear-shaped, basket-like tube section and FIG. 1c a plan view of this in the direction of the arrow A.

Nach der Zeichnung ist 1 der Rohrabschnitt aus Hart-PVC mit den um seinen Umfang gleichmäßig verteilten Stanzschnitten la zur Bildung von den durch Preßdruck und I Erhitzung herauszubiegenden Streifen ib, 1 und 1 bilden die rohrförmigen Endstücke des Abstandhalters.According to the drawing, 1 is the pipe section made of rigid PVC with the order its circumference evenly distributed punch cuts la to form the through Pressing pressure and I heating strips ib, 1 and 1 to be bent out form the tubular End pieces of the spacer.
