Heat-insulation energy-saving supporting bracket system for steam pipeline

The utility model belongs to the field of steam pipelines, and particularly relates to a steam pipeline heat insulation energy-saving supporting bracket system which comprises a first metal plate, a magnesium steel block and a second metal plate which are sequentially arranged from bottom to top, the first metal plate is used for being connected to a civil engineering support in a supporting mode, and the second metal plate is used for being connected with a steam pipeline in a supporting mode. A first aerogel layer is arranged between the magnesium steel block and the first metal plate, and a second aerogel layer is arranged between the magnesium steel block and the second metal plate. The aerogel is arranged on the two sides, and the magnesium steel block is arranged between the two layers of aerogel, so that a three-layer heat insulation structure is formed, the heat insulation effect is guaranteed, the structural strength is guaranteed, and heat loss of the steam pipeline can be avoided. 本实用新型属于蒸汽管道领域，具体涉
