FIELD: construction.
SUBSTANCE: invention relates to elongated element of frame structures. Long and thin-wall element with several sides extending along longitudinal axis so that element has multiple axial symmetry relative to longitudinal axis. Each axisymmetric side includes supporting surface of point of support and fastening wall, and connection surface for attachment of element to other structural elements. Connection surface recessed relative to bearing surface and is located so that when element is fastened by common fasteners through connecting surface, fasteners do not protrude from surface of support. Connective surfaces are provided with group of holes for fasteners. Also described is unit from such structural elements.
EFFECT: simplified assembly of frame structures.
