FIELD: civil engineering. SUBSTANCE: nodal joint of rods of spatial skeleton includes core of two interconnected cover plates with ports in the form of two intersecting through passages and vertical openings placed between horizontal rods coming together to form a node, tie bolts being passed through the vertical openings, coaxial horizontal rods retrained in the ports between core cover plates, shaped leaves connected with the core through tie-bolts, and inclined rods attached to the shaped leaves. Each pair of coaxial horizontal rods is made in the form of flexible strings. Through passages for securing coaxial rods in the point of intersection are bent and passing around each other. Through passages are provided with spiral channeling of the same congruent surface as the flexible strings. The flexible strings are prestressed. EFFECT: high-strength structure. 2 dwg |
