Pipe bolting for mine support sections

摘要

A pipe bolting for support arches consists of pipe bolts which with one end are supported on the side of a support section and with the other end partially surround a support section in association with a pressed-on and/or loose clamp and which are screwed tightly on the support section with hook screws and nuts as well as partially overlapping, the connection, partially surrounding the support section, of a pipe bolt in the form of a pressed-in and/or loose clamp having crimp deformations in the region of the hook screws. To increase the clamping effect and with regard to a simplification in terms of mounting and safety, the end of a pipe bolt, which end is supported in a continuous direction against the side (10) of the end of the preceding pipe bolt (8), which end overlaps the support section (1) and is fastened by means of hook screws (4, 6) and nuts (5, 7), has at least one recess (12) which overlaps the screw connection (6, 7) towards the ground by crimp deformation (15), and for final connection of the pipe bolts (8, 11) without loosening the previous screw connection (4, 5; 6, 7) a nut (13) is provided (Fig. 1). <IMAGE>
