Apparatus And Method For Connecting An End Of A Horizontal Beam To A Vertical Surface Of Supporting Structure
US Patent:
4171173, Oct 16, 1979
Filed:
Jul 17, 1978
Appl. No.:
5/925249
Inventors:
Nelson J. Hymans - Ralston NE
International Classification:
B25G 334
US Classification:
403189
Abstract:
Apparatus and method are disclosed for connecting horizontal beams to vertical surfaces of supporting structures. Two slidingly interconnecting elements are affixed, respectively, to a vertical surface of supporting structure, and an end of a horizontal beam and then positioned for positive stable coupling. The joint created by the elements is filled with grouting to substantially prevent movement of one element relative to the other element.
Tensioning Apparatus And Method Of Applying Tension To A Tendon
US Patent:
4192215, Mar 11, 1980
Filed:
Aug 28, 1978
Appl. No.:
5/937377
Inventors:
Nelson J. Hymans - Ralston NE
International Classification:
E04C 326, E21B 1900, F16B 1700
US Classification:
85 36
Abstract:
An apparatus and a method are disclosed for inducing torsion-free axial tensile stress in a tendon. The apparatus includes tapered wedge-grippers mounted on the tendon, an externally threaded hollow sleeve member with tapered inner surfaces concentrically mounted on the wedge grippers, and an internally threaded nut placed around the sleeve and in contact with a cooperating bearing surface through which the tendon projects. The sleeve is provided with a head having at least a pair of parallel surfaces which are engagable by a torque wrench for restraining it against rotation as the nut is rotated with a second torque wrench. The resultant movement of the sleeve together with interaction of the members of the apparatus results in torsion-free axial tensile stress in the tendon.
