FIELD: construction.
SUBSTANCE: invention relates to construction and can be used for production of frames, lintels, columns, arches, frames and other long bearing grid structures of pipes. Bearing structure with a grid from oval pipes includes belt and rigidly attached to them grid made with flattened ends of bent elements with a zigzag shape. Rod elements of grid have a flat-oval section with ratio of dimensions of 1/2.63, where larger dimension is located in plane of design, smaller - from plane.
EFFECT: technical result consists in reduction of labour intensiveness of manufacturing of bearing structures and reduction of costs thereon.
