Known bolted connections for the internal connection of two profiles have a fastening rod which is intended for insertion into the profiles and has two threaded parts each projecting into a connecting hole of the profiles. Connection is effected by using two fastening nuts which are intended to be fitted onto the two threaded parts and can be tightened against the connecting holes. This type of clamping has a substantial disadvantage. Thus, screwing of the two fastening nuts is made more difficult by virtue of the fact that, during tightening, one nut must be held with a first wrench while the other nut can be tightened with a second wrench. The bolted connection according to the invention does not have this disadvantage. This in fact permits the use of only one nut. To prevent the fastening rod from rotating when the nut is turned or slackened, the fastening rod is provided in an end section with at least one constriction so that a clamping jaw fitted onto this constriction in an axially nondisplaceable manner prevents rotation of the fastening rod. |
