THREE-DIMENSIONAL TOWER-TYPE TRUSS STRUCTURE Russian patent published in 2009 - IPC E04H12/08 

FIELD: construction.

SUBSTANCE: invention concerns three-dimensional bearing structure members in the form of a tower-type truss designed in particular for installation of various wireless, TV and radio antennas, and which can be also used for other high-rise industrial structures. The three-dimensional tower-type truss structure is made in the form of a regular truncated pyramid composed of the similar shaped sections of an equal height, which are formed by multiple elongated linear elements and multiple junctions, each composed of two subsystems so that the first subsystem of elongated linear elements forms the pyramid edges and the second subsystem of elongated linear elements, which have equal length within each section and are interconnected by their ends, forms continuous zigzag elements throughout the height of each face of the pyramid, whereby the first junction subsystem is made of Y-shaped plates regularly installed on each pyramid edge in the crossing points of three elongated linear elements, one of which forms a pyramid edge and two other ones form zigzag elements of the pyramid's adjacent faces in accordance with the principle of axial symmetry of the truss structure, which meets the condition of 360°/n, where n is the number of faces of three-dimensional truss.

EFFECT: increased bearing capacity per unit mass of the structure together with simplified method of installation and logistics.
