FIELD: construction.
SUBSTANCE: metal section of quick-assembled structures has a cross-section inscribed in a square; the section is cross-shaped in its cross-section and made in the form of four mutually perpendicular beams, on the end of one of which there is the first and the second branches directed to opposite sides and parallel both to the second and the third beams; on the end of the third beam there is the third branch directed to the side opposite from the second branch and parallel to the fourth beam, and distances between the second beam and the first branch, between the third beam and the second branch and between the fourth beam and the third branch are equal to each other.
EFFECT: enlarging operating capabilities due to use of a section without any fasteners.
