Abstract: An adjustable hanging bracket having an elongated spine with a longitudinal axis. The spine has a first portion and a second portion. First and second opposed ears extend from the first portion of the spine in a direction transverse to the axis. Each of the ears have distal ends. First and second opposed flanges extend from the spine in a direction transverse to the longitudinal axis and are adjacent to the first and second ears. The first and second flanges form an arcuate taper towards the second portion of the spine. A first and a second seat tab extend longitudinally from the second portion of the spine in a direction transverse to the longitudinal axis and forman acute angle with respect to the longitudinal axis of the spine. Each of the seat tabs have distal ends. The flanges define a plurality of fastener openings. The openings are aligned about a plurality of vertically spaced axes.

Abstract: A unitary truss clip for interconnecting adjacent truss members comprising a base, first and second top flanges extending from the base in opposite directions, first and second bottom flanges extending from the base in opposite directions and nail receiving openings in each of the top and bottom flanges.

Abstract: An anchor apparatus which provides corrosion protection for the exposed cable in a region around where the anchor body attaches to a tendon of a prestressed concrete slab is disclosed. A conduit is fastened to the inlet end of the anchor body. The other end of the conduit is taped or connected with heat shrink tubing to the covering on the tendon. The outlet end of the anchor body is closed either with a plug at an end anchor or with a second conduit and tape or heat shrink tubing at an intermediate anchor. Fittings are provided for inserting corrosion resistant grease into interior cavities as a second line of corrosion protection.

Abstract: A method for installing a new steel tendon and for repairing a damaged or deteriorated steel tendon in a prestressed concrete slab is disclosed. The repair method includes the steps of relieving substantially all stress in the defective original tendon, removing the original tendon, installing a new tendon in the space vacated by the original tendon, installing new concrete around the new tendon to replace any original concrete removed while removing the original tendon, and stressing the new tendon thereby again prestressing the previously structurally defective slab. Installation of a tendon where none has previously existed is similar except an original tendon need not be removed.
