Bridges with a latticed load-bearing structure made up of steel sections assembled by means of connection faces

摘要

The invention relates to the various methods for building bridges with a latticed structure made up of steel sections which are assembled by means of plane or cylindrical connection faces. These faces, which make it possible to assemble by welding, bolting or riveting, are either natural faces of members 1, or added faces 2 joined by welding - directly or via attaching components 3 - to the members 4. They can be provided with centring plates 5. This invention comprises wide applications in the construction of bridges with a latticed structure. IMAGE
