However, there are also a number of disadvantages to current pylon support systems, such as: (1) The support rod piece adopts a welding connection mode, so that the support rod piece has larger welding defects, and the welding position has low fatigue strength, large residual stress and low bearing capacity; (2) Because the support rod pieces are connected by welding, individual rod pieces cannot be replaced in time even if the individual rod pieces show small defects in the construction process, and the individual rod pieces are difficult to replace even if the individual rod pieces show large defects or have overlarge bending defects, so that the bearing capacity, the stability and the safety of the whole structure are reduced; (3) The support is excessively random to set up, the arrangement is unreasonable, and the rod pieces are arranged according to the optimal force transmission route without considering the economic and efficient principle.
Therefore, a more optimized and reasonable structural structure, higher strength of the joint, assembled and disassembled construction, easier and rapid replacement and maintenance of the rod piece and stronger bearing capacity and overall stability are required in engineering construction.
