POLE SUPPORT SECTION Russian patent published in 2008 - IPC E04H12/00 

FIELD: construction, road construction.

SUBSTANCE: invention pertains to the filed of assembling trussed bearing structures. The technical outcome is the increase in effectiveness due to lowering of transport losses along the whole way from the manufacturing factory to the site of installing the poles, and due reduction of labour intensiveness of assembling the supports in the construction. There is maintenance of the condition for parallelism or inclination and coaxiality of the section during assembly. That way, the fixed components are assembled under factory conditions. The support section for poles is in the form of a spatial trussed structure in the form of a parallelepiped or a truncated pyramid, formed by four bearing girdles, made from rolled metal or pipes, joined to each other by braces or bars. The spatial trussed structure is made in the form of two flat all-welded steel frames with a rectangular or trapezoidal shape, which present themselves as opposite borders of the section, and consisting of each of the two bearing girdles, joined to each other by welded braces or bars, as well as from separate frames. The frames have a rectangular or trapezoidal shape, and are fitted with braces or bars. The bearing girdles of the flat all-welded frames have openings or weld onto the strapping girdles with openings for assembling flat all-welded frames into the volume quadrangular in the cross-section of the structure, through mounting of separate frames onto the bearing girdles of the all-welded flat steel frames, with joining of these frames to each other using bolts.

EFFECT: increased effectiveness of trussed bearing structures with simplification of their assembly.
