Construction of suspended bridges or roofs with two masts

摘要

The construction has two or more masts (2), a load bearing cable (3) extending between two anchor points (5) on the ground and supported by the masts. The structure (1) is suspended from the load bearing cable by suspension rods (4), each attached to a ring (A1-An etc.) clamped around the cable (3). Each clamping ring is subjected to a load by its suspension rod which is tangential to the load bearing cable (3). To reduce this load there are one or more smaller, linking cables (10, 11, 12) with sections which extend to between clamping rings (A1 etc.). These sections are attached rigidly to the mast and the clamping rings and are successively less tensioned the further they are from the mast. The linking cable exercises a compensating force on the clamping rings to which is attached which partially compensates for the tangential load on the clamping rings. Pref. the cable (3) has a sheath (9) of high density polyethylene.
