Claims (15)
1. Bergbultningsförfarande vid vilket man i borrhälet insät-ter en rörformig bult som är smalare än borrhälet och har siliten tvärsektion och sedan expanderar bulten till förankring i borrhälet genom att den plastiskt deformeras till att expande-ra i borrhälet, kännetecknat av att expansionen sker utan plastisk förlängning av bultens perimeter.
2. Förfarande enligt patentkravet 1 , kännetecknat av att man använder en sluten bult försedd med ett tillopp (24, 25) och trycksätter bulten genom att ansluta dess tillopp till en extern tryckvätskebehällare sä att bulten expanderar och permanent förankras i hälet, varefter man avlastar bulten frän tryck.
3. Förfarande enligt patentkravet 1 eller 2, kännetecknat av att man använder en bult som har väsentligen cirku-lärt tvärsnitt med en enda längsgäende inbuktning som fore expansionen sträcker sig in förbi bultens centrum och efter fullföljd expansion i borrhälet kvarstär som en inbuktning.
4. Förfarande enligt nägot av patentkraven 1-3, kännetecknat av att man expanderar bulten tili anliggning mot hälväggen över större delen av dess längd och företrädes-vis över väsentligen hela dess längd.
5. Rörformig bergbult med sluten tvärsektion, känneteck-n a d av att den före användandet i sin tvärsektion har en pe-riferilängd som överstiger omkretsen av en cirkel som har en diameter lika stor som bultens största tvärmätt i tvärsnittet.
6. Bergbult enligt patentkravet 5, kännetecknad av att bulten bildar en sluten kammare och har ett inlopp (24) för tryckvätska i ena änden.
7. Bergbult enligt patentkravet 6, kännetecknad av att bulten före expansionen har en yttre periferi som är väsentligen cirkulär över en vinkel som överstiger 180° och bulten har en enda
