FIELD: construction; installation systems.
SUBSTANCE: group of inventions can be used in construction of bridges and other structures in which oscillatory movements and significant thermal expansion of load-bearing metal beams occur. The specified technical result is achieved by the method of fastening the elements to the cap of a metal beam. The plate is fastened to the cap of the beam, in which a hole is made that makes it possible to mount and displace the fastener rod, with which the subsequent structure is attached to this plate, through the specified hole in the plate the first U-shaped profile is fixed with edges bent into the groove and holes for mounting bolts and/or studs through them, made in the wall of this profile, located opposite the groove, fastening is carried out by a bolt-nut device through the groove of the first profile by pressing the nut to bent edges of this profile, and shape of the nut prevents it from turning in the profile cavity due to being pressured against the walls of this profile when the bolt is screwed into it, then a second U-shaped profile with edges bent into the groove is attached to the first profile, fastening is carried out using a bolt-screw device through the groove of the second profile by pressing the nut to the bent edges of this profile, and the shape of the nut prevents it from turning in the cavity of the profile due to being pressured against the walls of this profile when the bolt is screwed into it. EFFECT: improvement of reliability and durability of attachment of profiles to a beam.
