FIELD: construction.
SUBSTANCE: constructor of pre-fabricated demountable structures of shell type comprises bearing elements (ribs) and connecting units (connectors), with the help of which unified modules of the frame are assembled in the form of spatial isosceles triangles, hypotenuses of which are single-type arched ribs, and cathetuses are made either rectangular or arched depending on the type of a developed module, at the same time the frame modules between themselves are connected by single-type elements (hypotenuses or cathetuses). Arched ribs are formed by circular arcs of radius R, besides, the central angles of arcs in axes of spatial triangle tops are related by the ratio of 
where α is a central angle of an arched hypotenuse, β - a central angle of an arched cathetus, besides, length of a rectangular cathetus in axes of spatial triangle tops makes 
connection units of frame ribs are made of elements of 9 types: a central double-plane element (with a bending angle equal to π/2) for connection of single-type cathetuses to each other, and also left and right double-plane (with a bending angle equal to π/4) and triple-plane (with bending angles equal to π/2 and 3π/4 accordingly and rotation of bending axes by the angle of α/2) elements for connection of the arched hypotenuse with arched and rectilinear cathetuses, angles of bending and rotation of bending axes of connecting units are arranged so that the planes of longitudinal sections of cathetuses are perpendicular to each other, and the plane of the longitudinal section of the hypotenuse is either parallel to the line of crossing of planes of longitudinal sections of cathetuses (double-plane elements), or is turned relative to it by the angle α/2 (triple-plane elements).
EFFECT: simplified assembly and disassembly, transportation and storage.
