FIELD: construction.SUBSTANCE: construction kit of quickly erectable collapsible frames of wave-shaped rotational 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 rotation of a flat wave-shaped generatrix around the axis located together with it in a single plane; as the generatrix of the rotational shell they use a continuous curve, consisting of alternating convex and concave identical arched hypotenuses. Connection joints of the frame ribs are made of two types of connectors.EFFECT: reduction of bearing elements of a frame.1 tbl, 15 dwg |
