FIELD: construction.
SUBSTANCE: construction kit of collapsible frames of wave-shaped translational shells comprises bearing elements (ribs) and connection assemblies (connectors), with the help of which they assemble unified frame modules in the form of adjacent spatial isosceles right triangles, hypotenuses of which are identical arched ribs, and legs are made rectilinear or arched. The surface of the shell is formed by the method of translation - reciprocal movement of the flat wave-shaped generatrix along its perpendicular wave-shaped guide; as the generatrix and guide translational shell they use mutually perpendicular curves made of alternating convex and concave identical arched hypotenuses. Connection joints of the frame ribs are made of two types of connectors.
EFFECT: reduced quantity of bearing elements of a frame.
