FIELD: construction.

SUBSTANCE: method comprises the assembly of arches in horizontal position from the same elements by the hinged connection of their ends to the joint plates by central bolts, giving arches the desired shape, rigid fixation to the joint plates, subsequent installation of arches into the design position, installation of hammer beams on arches and laying the fence on them. Joint plates are made of segments of thin-walled rectangular or square pipe, and the ends of the same elements are placed inside the joint plates, on the upper and lower shelves of which longitudinal and transverse slots with formation of cantilever portions are made.
