PROCEDURE FOR ASSEMBLY In section size CIRCULAR GITTERSTAENGER OF STEEL AND A FITTING FOR THE PURSUIT OF PROCEDURE

摘要

When joining tubular steel lattice members in a space structure, which is built up over box-shaped modules, and where the members (1,5) are joined in the corners of the box-shaped modules under formation of lattice nodes (4), elliptical assembling devices (6,12) are used. The elliptical assembling devices consist of two elliptical plate pieces (7,8) which are placed at right angles to each other with a mutual minor axis. The devices lie with their side backing to member ends, which are cut into plane sections at an angle of 45 DEG with the member axis.
