The coupling may attach to a slot in the frame at substantially any position along the length of the frame thereby enabling the interconnection of adjacent PV modules along both an x and y axis. The apparatus may further provide a rotating portion and locking portion, mounting brackets for direct connection to a mounting surface, grounding teeth, and a twist-lock engagement means for interlocking and aligning PV modules in the array.

An assembly for reinforcing a longitudinal section of a pole, includes at least two load transfer rings formed by sleeve segments having radically opposed mating ends. The rings are adapted to fit onto the outer surface of the pole so as to circumferentially encompass the pole. The sleeve segments are connected at their ends by a nut and bolt assembly, wherein tightening of the nut and bolt assembly creates a radial clamping force to squeeze the load transfer rings onto the outer surface of the pole for holding the rings in fixed relation thereon. Elongated stiffener members are fixedly attached to the load transfer rings by a nut and bolt assembly or by welding. The load transfer rings may also be partially welded to the exterior of the pole if structural load bearing demands require additional capacity.

A modular building construction where each module consists of self-contained molds to allow concrete to form within the walls of each module as well as between the modules when two or more modules are placed together. The structural load capacities of the modules are transmitted directly into the concrete within the wall without bearing directly on the module below. The forming structure for the modules can be fabricated either using wood or metal construction. The exterior and interior wall finishes are the resulting structure of the molds. Since the molds are self-contained the walls can consist of, either drywall, rigid insulation, thin brick or siding just to name a few. The interior forming structure can extend into the concrete footing or above or to adjacent modules to structurally secure the modules together. The modules can be built with a flooring structure as well as ceiling. The interior walls as well as the floor and ceiling also function as wall supporting braces. The exterior walls have many different forming molds to accommodate many different construction situations. Some forming structures are formed with a thermal break between the exterior and interior forming structure. The thermal break allows the wall to also be used as a heating or cooling distribution system. Different types of connectors are described allowing for the connectors to be hidden. Several methods are shown how the electrical distribution can be provided within a concrete wall by using the forming structure within the mold. A ribbed concrete mold can be formed for a poured-in-place wall as well as for a floor and roof system. Temporary floor bracing can be used when pouring the flooring system, or only just the concrete beams can be poured and the floor can be poured later. The flooring system can be used as concrete wall or as a roof structure.

Pre-assembled self installing platforms with improved performance due to additional rotational restraint to supporting legs and methods of installation. The platform includes a hull, legs movable relative to the hull, at least one brace frame movably connected to at least two of the legs. Upon installation, the brace frame may be positioned at a desired elevation and rigidly secured to the legs, providing rotational restraint to significantly reduce leg stress and increase rigidity of the legs.
