METHOD TO MANUFACTURE SEGMENT TRUSS Russian patent published in 2013 - IPC E04C3/11 

FIELD: construction.

SUBSTANCE: method includes manufacturing of belts, installation of rods of a triangular lattice in truss units and their connection by means of bolts or welding. Belts are made as through from two C-shaped profiles or channels. Lattice rods are made of a similar single profile. Lattice rods are installed as overlapping onto walls of belt profiles of the truss or on its gusset plates. Previously 3D sheet plates of H-shaped cross section are manufactured for units of belt fracture. Plates have contact surfaces of parallel sheets with elements of the truss equal to the height of the lattice profile cross section. For span units of the upper belt the parallel sheets of H-shaped cross section of the plate are arranged as stepped. The height of the step is equal to the thickness of the plate sheet. Then lattice rods and straight sections of the truss belts are attached to the plates. Afterwards the remaining lattice of the truss is installed between belt profiles of the truss, and planks of the truss belts are fixed.

EFFECT: simplified manufacturing.
