A column assembly includes a two or more piece interlocking column assembly having at least a first linear section configured with an annular curve about a first short dimension, said at least first linear section having a first exterior surface, a first interior surface, and a first set of opposing edges, wherein said first set of opposing edges are configured with a first opposing male/female latch mechanism; and at least a second linear section configured with said annular curve about a second short dimension, said at least second linear section having a second exterior surface, a second interior surface, and a second set of opposing edges, wherein said second set of opposing edges are configured with a second opposing male/female latch mechanism, wherein said first opposing male/female latch mechanism and said second opposing male/female latch mechanism are configured to friction fit thereto each other.

A utility pole is reinforced by assembling and installing a reinforcement channel assembly comprising a lower reinforcement channel driven into the ground alongside the pole, an inner splice plate supported on and against an inner surface of the lower reinforcement channel, an upper reinforcement channel supported on and against an outer surface of the inner splice plate, and an outer splice plate supported on and against respective outer surfaces of upper and lower portions of the upper and lower reinforcement channels. An outer splice plate is secured to the inner splice plate, sandwiching between them the respective upper and lower portions of the lower and upper reinforcement channels, and the upper reinforcement channel is secured to the pole.

A modular composite utility pole has a plurality of sections, each with a tapered hollow tube having a plurality of plies, wherein a first end has a larger diameter than a second end, wherein each section is adapted to join at least one adjoining section at a joint wherein the first end of an upper section overlaps the second end of a lower section, the lower section having a ledge proximate to the second end of the lower section, with a fastener passing through the joint via apertures in the sections, and wherein, when the modular composite utility pole is erected, the joint is self-located by the joint features, and wherein substantially all vertical load is transferred between sections via the a surface of the second end of the upper section resting upon the ledge of the lower section. Also disclosed are individual sections and methods of making them.

A bracket has: a plate having bolt holes and a utility pole mount; a clamp secured to the plate, the clamp comprising cooperating screw pile shaft receiving parts having laterally extending flanges, the flanges having fastener receiving openings for securing the clamp around a screw pile. A combination has: a bracket; a utility pole extended from a ground surface, in which the plate is bolted to the utility pole through the bolt holes in the plate; and a screw pile fastened to the clamp and penetrating the ground surface.

An axial reinforcement system is disclosed that provides a shell (i.e., a form or jacket) that protects a weight-bearing member (e.g., a cement column) from a corrosive environment and which also substantially increases the structural capacity of the weight-bearing member. The shell is integrated with “positioners” and reinforcing elements, the combination of which offers several advantages over conventional shells. The positioner is attached directly to the shell and the positioner is, in turn, secured to a reinforcing element, which can be a reinforced steel, such as rebar, or a carbon fiber reinforced polymer material. The axial reinforcement system has been found to substantially increase the structural rigidity of the weight-bearing member, while at the same time protecting the weight-bearing member from corrosion and is also simple to install.

An axial compression steel tubular column with internal local restraint and filled with high strengthen compound concrete containing normal-strength demolished concrete lumps and a construction process. The axial compression column includes a steel tube (1), high-strength fresh concrete (2), normal-strength demolished concrete lumps (3), a spiral stirrup (4), and longitudinal erection bars (6). The spiral stirrup (4) is arranged at a middle part inside the steel tube (1). The high-strength fresh concrete (2) is poured and the normal-strength demolished concrete lumps (3) are put alternately inside the steel tube (1). A compressive strength of the high-strength fresh concrete (2) is 30˜90 MPa greater than that of the normal-strength demolished concrete lumps (3).

An apparatus for plumbing a transmission or distribution pole comprising: multiple pole brackets connected with an adjustable ratchet strap; multiple scissor jacks with each having a jack mount; at least one power drill or hand crank to adjust the scissor jack; whereby the pole can be efficiently adjusted into the proper plumb or leveled position.
