POLYSYSTEMIC TRUSS Russian patent published in 2014 - IPC E04C3/04 

FIELD: construction.

SUBSTANCE: polysystemic truss represents a structural system made of a stiff bearing guy element, an upper belt on two supports and a lower belt, stiffly connected to each other by stands. The truss comprises four interacting structural systems, combined into a single system with an open-frame grid from stands and/or suspensions and two support parts with a support stand and two support assemblies in each part. The first system includes a guy element and an upper belt, stiffly connected in upper support assemblies; composite sections of different length of stands and/or suspensions stiffly joined in assemblies of polygonality of the guy element and panel assemblies of the upper belt. The second system includes an arch element and a lower belt, stiffly connected in lower support assemblies; composite sections of different length of stands and/or suspensions stiffly joined in assemblies of polygonality of the arch element and panel assemblies of the lower belt. The third system comprises a guy and arch elements, stiffly connected to each other in the plane of the truss in two points of their crossing; upper and lower belts and support stands stiffly combined in upper and lower support assemblies with the guy and arch elements; composite sections of various length of stands and/or suspensions, stiffly connected in assemblies of polygonality with guy and arch elements and in panel assemblies with upper and lower belts. The fourth system includes upper and lower belts, support stands, rigidly connected in upper and lower support assemblies; stands and/or suspensions, stiffly connected in panel assemblies of upper and lower belts and in assemblies of polygonality of the guy and arch elements.

EFFECT: realisation of new conditions of interaction of truss elements, increased technical and economic effectiveness.
