Abstract: 681,420. Anchor bolts. ECUER, R. May 16, 1951 [Jan. 29, 1951 ], No. 11446/51. Class 89 (i) An anchor bolt comprises a sleeve longitudinally divided into two or more sections with cam inclines 4b, 5b, leading from openings 4, 5 at their edges. A core bolt B has cam projections C, D that engage the inclines 46, 5b respectively. A weakened section S is provided between the projections. On applying tension to the bolt after the device has been inserted in a hole drilled in rock &c., teeth 6 maintain the sleeve in position during expansion of the inner end by the co-acting parts C and 4b. During this expansion the part D travels idly in a part 5c of the opening 5. If the anchorage be secure, further tightening of the nut on the bolt causes fracture at S and the part D then coacts with the inclines 5b to expand the other end of the sleeve. If the rock be faulty, the sleeve pulls out of the hole and an insecure anchorage is avoided. The parts are held together initially by a light binding at E. More than two sets of inclines may be used with a further weakened section between the succeeding inclines. These sections must be so graded that fraction takes place in sequence, from the innermost section, outwards.
