Prefabricated pressed metal section footbridge - has two self supporting side sections receiving ends of central section
Реферат: The pedestrian footbridge consists of three prefabricated sections, two identical self-supporting side columns and a central transverse section, the ends of which rest on the top of the side columns. The central section can be quickly lifted by a crane to allow an exceptionally high vehicle to pass underneath. The entire structure is easily dismantled and transported elsewhere. The bridge is made of sheet-metal which is cut, bent round a mould and then the shapes are assembled to form caissons whose section corresponds to the calculated stress and bending moments.
