METAL TRIANGULAR TRUSS Russian patent published in 2015 - IPC E04C3/08 

FIELD: construction.

SUBSTANCE: invention relates to the construction, namely, to metal light, mostly prefabricated covering constructions of buildings and facilities. Metal triangular truss, which includes upper and lower belts made of bent metal profiles, as well as braces connected by means of detachable fasteners, is proposed. A distinctive feature of the proposed truss is that the upper belt is made of two paired cold-formed profiles connected with clearance with formation of symmetrical cross-section, the lower belt is composite made of five or three paired cold-formed profiles, constituting the single rod, besides part of paired profiles belonging to the lower belt, is connected without gap, and part of paired profiles of the lower belt is connected with gap, brace struts, connecting the upper and lower belts, are made of profiles with cutting section, which is located apart from two shelves, in this case the saved areas of cutting are placed in gaps of the upper and lower belts and fixed by means of detachable fasteners.

EFFECT: increase of the load-bearing capacity, stiffness and stability.
