Abstract:
A friction bolt assembly includes: an expansible sleeve having a tubular body between leading and trailing ends, which body has a longitudinally extending formation about which the body resiliently deforms and which formation extends along at least part of the body, ending at the body leading end; a rod extending through the sleeve body and between first and second ends and on which a projecting part is defined between the trailing end of the sleeve body and the second end; an expansion element on the rod at the first end; a first load bearing formation on the projecting rod part, moveable along the projecting part to abut the sleeve trailing end; a load applicator on the projecting part of the rod; and a second load bearing formation mounted over the projecting part of the rod between the first load bearing formation and the load applicator unit.

Claim (Index 13):
A method of installing the friction bolt assembly according to  claim 1  in load support of a rock face, the method including the steps of:\n a) inserting the friction bolt assembly at least partially into a pre-drilled rock hole in the rock face, first end leading, until the sleeve and the first load bearing formation, abutting the trailing end of the sleeve, are fully received in the rock hole; \n b) spinning the load applicator means to move the second load bearing formation into abutment with the rock face; \n c) torqueing the load applicator means to actuate the rod to move relatively to the sleeve to draw the expansion element into bearing engagement with the sleeve such that the first load bearing formation engages with the sleeve at the trailing end in friction fit; and \n d) torqueing the load applicator means further to actuate the rod to move relatively to the sleeve to draw the expansion element into or within the sleeve to cause the sleeve body to radially outwardly deform about the longitudinally extending formation into frictional engagement with the walls of the rock hole and to cause the second load bearing formation into load bearing engagement with the rock face.
