ABSTRACT:
An anchor bolt for securing a bracket to a roof supported by a beam is disclosed. The anchor bolt includes a shank having a threaded upper end and a lower end and extends through a hole in the roof located adjacent the beam. A nut threaded onto the threaded upper end is tightened against the bracket to draw the bracket securely against the upper surface of the roof. The shank extends through the hole along a first side of the beam to a lower edge of the beam. The anchor bolt includes a hooked section attached to the lower end of the shank for anchoring the anchor bolt to the lower edge of the beam. The hooked section includes a retaining end for extending along a second side of the beam to prevent the hooked section from slipping off of the lower edge of the beam when the nut is tightened against the bracket. The retaining end is inclined with respect to the shank by an angle selected to permit the hooked end of the shank to be conveniently passed through the hole from the outside surface of the roof.
