FIELD: construction.
SUBSTANCE: invention relates to construction and can be used for fabrication of tubular lattice (bent-welded) profiles of different buildings and structures. Method of making lattice structures of tubular (bent-welded) profiles includes formation of a structure lattice to adjoining belts and its fixation in a spatial position with subsequent grooving of butt-end edges of lattice elements in the zone of their connection along the lines of connection with the belts. Herewith ends of the compressed lattice elements are covered with side faces of the stretched elements of the same lattice.
EFFECT: technical result is reducing consumption of structural material, reduced labor input, as well as expansion of layout and unifying capabilities of lattice structures.
