Abstract: An improvement for an aluminum lattice sector frame of the type used for supporting wireless communications antennas and designed to be mounted on a communication tower, is provided. Mating extruded components are used to provide fixed connections which restrict relative rotation and translation between connected parts while presenting a round tubular outside cross-sectional profile thereby reducing the effective projected wind load area of the frame. The fixed component connections greatly reduce the overall deflection of the frame under applied combined dead, wind and ice loading.

Abstract: An improvement for a bracket assembly of the type used in lifting and supporting a structure or shallow foundation element on a pile is provided. The bracket assembly rests on top of a deep foundation pile positioned adjacent to a structure. The bracket has inside and outside sections, the inside section is a weldment consisting of a bearing member which engages and attaches to the structure or foundation element. The inside section also functions as a guide for installing a pile. The outside section is further divided into upper and lower parts. The lower outside section has a pile guide and a spaced apart U-shaped adjustment bolt that together cradle the pile. The upper outside section caps the pile and attaches to the lower outside section using threadably adjustable rods. The outside section attaches to the inside section thereby fixing the bracket assembly against horizontal translation and rotation about a horizontal axis with respect to the pile.
