COLLAPSIBLE TRUSS Russian patent published in 2000 - IPC

FIELD: construction engineering. SUBSTANCE: collapsible trusses can be used as load-bearing structures in coverings of mobile buildings and other objects, and also as temporary load-bearing structures in reconstruction of objects. Installed in parallel to triangular lattice of truss are connecting rods which are located away from lattice in height at distance not over one third of length of connecting rod body. Triangular lattice is attached to lower girth in units of pivoted connection of components of connecting rod bodies of lower girth. Connecting rods are attached to upper girth in units of pivoted connection of its components. Aforesaid arrangement of components allows for speedy mounting and dismantling of truss without use of special fixing members. EFFECT: higher efficiency. 2 cl, 7 dwg
