Abstract

Et ekspansjonsverktøy med en sylinderformet ekspansjonstapp (5) av flere syiindersektorformede ekspansjons- ledd (10), som med en holderdel holdes og føres utskiftbart på en endeside av et hus (1). Ekspansjonstappen ( 5) er forsynt med en delvis kjegleformet innerboring (6) som griper inn i en ekspansjonskjegle (4) som samvirker med aktiviseringsmidler (2) som driver frem ekspansjonskjeglen (4) inn i ekspansjonstappens (5) innerboring (6) for utvidelse av en rørende (9) anbrakt på ekspansjonstappen (5). Videre er ekspan- sjonstappen (5) på sin frie ende forsynt med en avf asing ( 9 ). Mellom avf asingen ( 9 ) og en fortykkelse (11) som holderdelen går ut fra, befinner det seg minst én ut- sparing (18) som forløper i omkrets- retningen over hele ekspansjonstappens (5) omkrets.
