SHRENGEL BEAM Russian patent published in 2018 - IPC E04C3/10 

FIELD: construction.

SUBSTANCE: invention relates to building structures and can be used as main beams of coatings and ceilings of industrial and civil buildings, for example bearing elements of overpasses, pedestrian crossings, technological overpasses, etc. Technical result is achieved due to the fact that the truss beam consists of a stiffness beam, racks, tightening and connection joints. Racks are located with a slope from the point of sag tightening at an angle to the stiffening beam 10÷90° with the formation of the beam compressed belt sections between the joints with a length longer than the sections length of the stretched tightening zone, where the joints at the tightening are shifted to the point of sag tightening.

EFFECT: technical task is to reduce the material consumption of the structure, increase reliability and stability against progressive destruction under the influence of distributed uniform and uneven loads.
