FIELD: construction.SUBSTANCE: invention relates to construction and can be used for node connections of space structures of buildings and other structures, for example, cross-bar structural systems or structural coating boards (floors). Structural node connection, mainly of round pipes, includes intersecting rods of belt grids with end plugs and cut-in zigzag planks, as well as diagonal grid elements with mashed and bent flat tips. Each of the tips is located between extending parts of the cut-in planks and is attached to them by means of bolts inside coaxial holes. Herewith the cut-in zigzag plates have the shape of isosceles trapezoids, lateral sides of which coincide with bending lines of the flat tips.EFFECT: technical result is reducing material consumption and labour intensiveness of manufacturing and assembling.1 cl, 7 dwg |
