PENTAGONAL FORMED 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 in a formed hollow section of a pentagonal contour with one horizontal face (shelf), two vertical faces (walls) and two inclined faces, as well as with gussets from the crimps of blanks docked together along the entire length, the section has the pentagon shape with an angle of 90° between inclined faces, the height of which is twice the size of the gusset, or the pentagon shape with an angle of 120° between oblique faces, which height is 1.1415 times larger than the size of the gusset.

EFFECT: technical result of the proposed solution is equal stability (equistability) of the formed hollowed sections from the plane and in the plane of the construction, an increase in the bearing capacity, a reduction in the construction height.
