FIELD: construction.
SUBSTANCE: method of bolt attachment of pin constructions of thin-wall profiles involves installation of washers and high-strength bolt in the hole made in attached elements. On one side of attached elements there installed is washer with annular protrusions of triangular cross section shape, and on the other side of attached elements there installed is mating washer with annular slots of the cross-section profile similar to that of protrusions; at that, surface area of cross section of washers is taken more than the surface area of loosening of the section of attached element with the hole for the bolt.
EFFECT: increasing carrying capacity of the attachment, simplifying the fabrication of its elements.
