FIELD: construction.
SUBSTANCE: invention relates to bridge construction and can be used in construction of span bridges from structural glass composites. Said span structure comprises main multiple trusses with cross grid, crosswise links and load-bearing bridge structure made of fiberglass profiles, and consists of mounting blocks comprising main trusses, joined in pairs by transverse links, comprising transverse beams with grid elements, and multi-ribbed open from below pultrusion fiberglass profile, supported by middle longitudinal ribs on transverse beams, and extreme ribs on top belts of main trusses, and combined with them by means of bolt joints. Mounting units are installed on supports on transverse slope diagram and connected to each other by means of arrangement of sections of bridge cloth between mounting blocks of flooring profiles, transverse beams with grid elements and bolt connections.
EFFECT: technical result is increased payload capacity of span structures, reduced material consumption and labour intensity of their manufacture and installation, increased durability and operational reliability of bridges using span structures from structural glass composites.
