Abstract
A pair of truss legs forming an A-frame-shaped truss foundation system, wherein each truss leg is formed from a hollow lower screw anchor having threading around its lower end connected to an upper leg, wherein both the screw anchor and the upper leg have corrosion protection layers formed on their inner and outer surfaces thereof, but wherein only the screw anchor also has a second corrosion protection layer formed over the first protection layer on its outer surface only.
Claims7
A truss foundation system comprising:
- a pair of screw anchors, each screw anchor comprising an elongated body with a circular cross section that is open at both ends;
- a pair of upper legs, wherein each upper leg has a first corrosion protection layer made of a first material and each screw anchor of the pair of screw anchors has at least one second corrosion protection layer made of a second material that is different than the first material;
- a driving coupler at one end of each screw anchor for driving the screw anchor that is received in one of the pair of upper legs to form a single truss leg;
- and
- an adapter with a pair of connecting portions oriented at opposing angles that are received in a respective upper leg of the pair of upper legs for joining the adapter to each single truss leg to form a unitary truss foundation with the ground.
