Abstract

En fremgangsmåte for å tilveiebringe en fjellbolt (2) for fjellbolting, idet en fjellbolt (2) med en rørformet boltdel (4) med et lukket tverrsnitt, blir satt inn og ekspandert for bærende kontakt i et borehull (3) i en fjellstruktur (1). Lengden av den rørformede boltdel (4) bestemmes slik at den maksimale fi-iksjonskraft ved trekking inne i et borehull (3) av en fjellbolt med en rørformet boltdel med denne lengde, er under en bestemt maksimumsverdi. Oppfinnelsen angår også en fjellbolt.A method of providing a rock bolt (2) for rock bolt, wherein a rock bolt (2) having a tubular bolt member (4) having a closed cross-section is inserted and expanded for bearing contact in a borehole (3) in a rock structure (1). ). The length of the tubular bolt member (4) is determined such that the maximum frictional force when pulling inside a borehole (3) of a rock bolt with a tubular bolt member of this length is below a certain maximum value. The invention also relates to a rock bolt.
