Abstract

In holes cut out from concrete, for subsequent introduction of bolts, this is applicable where it is preferable that the deeper area of the holes should be bored, rather than metal-bounded. There is steel, or other metal, walling round the holes in the vicinity of the mouth, and in the deeper part the hole is produced by a bar-shaped element which is concreted in, and which can be withdrawn or bored out; this element may be round or angular in cross-section, and may be made of wood. At the metal-lined end there may be a funnel-shaped socket, concreted in; or a perforated flat steel or angled steel piece.

Description

Bei Beton für s-osteres Einsetzen von Bolzen ausgesparte Löcher In vielen Fallen ist insbesondere im tieferen Lochbereich ein gebohrter Abschnitt einem metallisch begrenzten vorzuziehen.Holes In many traps, especially in the deeper hole area, a drilled section is one Metallic limited ones are preferable.

Erfindungsgemäß besteht die Aussparung aus einem mündungsseitigen Lochbereich mit metallischer bzw stählerner Wandung und ist im tieferen Bereich durch ein einbetoniertes, ziehbares und/oder leicht ausbohrbares stabförmiges Element vorbereitet Das stabförmige Element kann runden oder eckigen Querschnitt haben iin-d z.B. aus Holz, gefertigt sein, wobei der Durchmesser Lufttrocken unter und längere Zeit gewässert über dem Lichten des mündungsseitigen lochbereichs liegen kann.According to the invention, the recess consists of a mouth-side Hole area with metallic or steel wall and is in the deeper area by a concreted, pullable and / or easily drilled rod-shaped element prepared The rod-shaped element can have a round or angular cross-section iin-d e.g. made of wood, the diameter being air dry below and longer Time watered over the clearing of the mouth-side hole area can lie.
