Large-span steel cover beam construction method based on steel support

The invention discloses a large-span steel cover beam construction method based on a steel support, which comprises the following steps: adding a pier top steel support between gate-type pier columns, firstly arranging a bracket structure during construction, then installing the steel support on the bracket structure, and installing a steel cover beam after a frame structure is formed between the steel support and the pier columns. The structure and the construction sequence are improved, the load of the upper structure is borne by the steel support and the steel cover beams together, the stress condition of the steel cover beam structure is improved, the pier top is reinforced through the steel support, and the construction efficiency is improved. In the construction process, the steel support can serve as a support to support and adjust the position of the block structure of the steel cover beam, and the construction difficulty and the safety risk of the pier and the pier top when the cover beam is fixedly
