TRIANGULAR HOLLOW PROFILE Russian patent published in 2018 - IPC E04C3/07 

FIELD: construction.

SUBSTANCE: proposed technical solution relates to the field of construction and can be used as rod elements in the development of load-bearing structures of buildings and structures of various purposes. In the particular case, these can be the rod elements of the chords of run-through and non-run-through coatings. This technical result is achieved by the fact that the curved profile of the closed cross-section of the triangular outline with the shapes of the bent edges of the blanks docked along the entire length has the shape of an isosceles triangle with an angle of 90° between equal parties, whose height is 1.5 times larger than the size of the facia, or the shape of an isosceles triangle with an angle of 120° between equal sides, where the size of the filament is 0.568 of its height.

EFFECT: same stability (uniform stability) of the bent profiles from the plane and in the plane of the supporting structure, an increase in the bearing capacity, a decrease in the construction height.
