ABSTRACT:
The present invention is a truss system constructed of rigid members and cables. In a preferred embodiment, the rigid members are used drill piping. Two inclined upper members are joined together at an angle to form a truss peak junction. A vertical member connects to and supports the lower end of each inclined upper member. The bottom of each vertical member sits in a collar attached to the top of a foundation member located in the ground. A tensioning member is perpendicularly attached to each inclined upper member near the midpoint of the inclined member. For each inclined upper member, a cable attaches to the inclined upper member near the truss peak, runs through a penetration in the tensioning member, and attaches to the lower end of the inclined member. Finally, a cable with first and second ends has its first and second ends secured so as to apply tension that opposes spreading of the lower ends of the inclined upper members.
