Clamping beam, has pressure pipes for applying tensile pre-stress on outer layer parallel to beam longitudinal axis, and vertical frames connected together via single-axial force transmission element running within outer layer

摘要

The clamping beam (1) has an outer layer (3) circulating around a beam longitudinal axis (2). Two vertical frames (4) define cross section of the clamping beam perpendicular to the beam longitudinal axis. The vertical frames are fixedly connected with the outer layer. Pressure pipes (5) act on the vertical frames. The pressure pipes apply tensile pre-stress on the outer layer parallel to the beam longitudinal axis. The vertical frames are connected together via a single-axial force transmission element i.e. towing rope, running within the outer layer.
