Construction system for constructing e.g. double curved lattice shell for barrel roof of temporary building, has detachable node elements connecting rods with each other, where rods are variable in numbers, length and angular dimension

摘要

The system has detachable node elements connecting rods (1) with each other, where the rods are variable in numbers, length and angular dimension. Spacing between the node elements is bridged by three divided elements. A coil-shaped cylinder (7) functions as an inner spacer for identical joint tabs (6) that are radially arranged around the cylinder. The tabs and screw fasteners (9) are arranged in a radially opened area between rings (8) and the cylinder such that angular tolerance is realized between the tabs and the screw fasteners.
