<p><P>PROBLEM TO BE SOLVED: To provide a profile connecting system comprising profile bars and connecting elements. <P>SOLUTION: The profile bars have at least one axial elongated hole and on the profile outer sides slots for nut block connections. In order to be able to assemble profile connections with minimal material and labor expenditure and in order to be able to avoid premachining operations on profile bars using machine tools and at the same time be able to transmit large forces, it is proposed to insert and fix an abutment, for example a threaded insert in a self-cutting manner into the bore of an axial elongated hole in a first profile bar 30. Adjacent to the installation length of the threaded insert and of the head of a screw, an axially running wrench opening is to be provided in the tubular body of the axial elongated hole. The length and width of the wrench opening is to permit guidance therethrough of a socket wrench, with joints or with a substantially spherical socket wrench head with flats, at an insertion angle to the longitudinal axis of the profile bar and the coupling of the socket wrench to the head of the screw. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
