ABSTRACT:
Adjustable means for fastening heavy precast concrete panels for walls or floors, structural concrete beams, girders, and machinery to foundations vertically, horizontally, or in any plane. An internally threaded hollow member is anchored to a panel member which is to be mounted on a supporting structure with bolts; the member having numerous fastening points designed into it. Alternatively, the hollow member is placed into a foundation so machinery can be bolted down. An externally threaded hollow member which can rotate through 360.degree. is mounted in the threads of the first hollow member, and is axially adjustable therein, the second member having a tapering hollow interior keyway space extending perpendicular to the axis of the second member. The upper three-quarters of the tapered keyway sides have fine thread-like striations and a tapering internal threaded nut fits into the hollow tapering space, the nut having corresponding striations on its tapering sides. Now both tapering hollow keyway and tapering nut inserted into it can be rotated 360.degree., and by magnetic means, the tapering nut can be moved along the entire length of keyway and the nut held at any location or attitude therein by magnetic means. Upon alignment of tapering internally threaded nut and bolt through a hole in a structural member, the bolt will pull the nut up in tapering hollow member securing the concrete panel to structure.
