METHOD OF INSTALLING A BOLT IN THE TRAPEZOIDAL PART OF THE WALL OF A THIN-WALLED PROFILE Russian patent published in 2023 - IPC E04C3/08 

FIELD: construction.

SUBSTANCE: invention relates to a method for installing a bolt in a junction of bars of a lattice structure. The method of installing a bolt in the junction of bars of a lattice structure, including a compressed belt of paired thin-walled profiles with a trapezoidal part of the wall, connected by bolts with a sheet gusset, consists in the fact that a fixing cylindrical element is temporarily installed in the area of the trapezoidal part of the wall on both sides of the location of the bolt, which provides fixation of a part of the wall, after which the bolt is tightened until the profile wall comes into contact with the sheet gusset. When the bolted connection is completed, the cylindrical elements are removed from the assembly.

EFFECT: reduction in labour costs when connecting profiles during installation.
