Benefits of technology
The patent describes an invention that provides a method for creating structures using pre-fabricated interchangeable planar trusses that can be easily and quickly manufactured, transported, and assembled. These structures made of pre-fabricated trusses provide the same or better structural performance compared to structures not made of pre-fabricated trusses. The invention includes a method for manufacturing interchangeable planar trusses by cutting and staging truss components, rigging them together, welding them into assembled trusses, and quality assuring them. The assembled trusses can then be galvanized as a whole structure, reducing costs associated with individual components, sorting, and transportation. The technical effects of this invention are reduced manufacturing costs, improved structural performance, and more efficient and cost-effective assembly and transportation of structures.
Problems solved by technology
The specialized truss designs increase the design costs, production costs, transportation costs, assembly cost, etc., which all significantly increase the overall cost of a structure that utilizes trusses.

Embodiment Construction
[0068]Embodiments of the present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all, embodiments of the invention are shown. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.
[0069]Large steel structures used in various applications are typically manufactured off site as individual members, and are either delivered to the assembly site in bundles of like members for assembly at a later date, or pre-assembled offsite in three-dimensional sections which are shipped to a destination, and thereafter, the sections are assembled into the final structure. With respect to the bundled configurations, assembly of the final structure is a labor intensive process that is very expens...

Description
FIELD[0001]This invention relates generally to the field of trusses, and more particularly embodiments of the invention relate to truss structures that can be used in various support applications and methods of manufacturing such structures.BACKGROUND[0002]Trusses are structural components that have one or more triangular, square, rectangular, etc. units constructed with chord members and web members that are secured together in various patterns. Trusses are used as structures for a variety of applications. For example, trusses can be utilized in structures such as bridges, buildings, electrical towers, wind towers, conveyer supports, cellular telephone towers, solar supports, construction scaffolding, etc. External vertical, transverse, moment, and torsion forces act on the trusses in the structures and place the members in tensile and / or compressive stress. The forces can be caused by wind, ice, heat, gravity, support loading, etc. In most applications trusses must be specifically...
