FIELD: construction, particularly structures of thin sheet cold-formed profiles with built-in frames for all-purpose arch building construction.
SUBSTANCE: arch-type covering structure comprises thin sheet cold-formed profiles connected with each other and support pads spaded apart a distance equal to cold-formed profile width and welded to embedded members of reinforced concrete floor panel. The embedded members are adapted to secure cold-formed profiles by means of bolts. The covering structure is reinforced in support zones with additional thin profiles having 500-1000 mm lengths. The additional thin profiles are connected with arch profile by composite rivets.
EFFECT: increased load-bearing capability of building.
