Saddle structure of C type liquid cargo tank and installation method of saddle structure

The invention provides a saddle structure of a C type liquid cargo tank in the field of shipbuilding and an installation method of the saddle structure. The bottom of pressure-bearing stow-wood in thesaddle structure is located in a stow-wood groove. The space between the pressure-bearing stow-wood and the stow-wood groove is filled with a first epoxy resin layer. A partition plate is arranged between the first epoxy resin layer and the pressure-bearing stow-wood. The partition plate is fixedly connected with the first epoxy resin layer. Due to the adoption of the saddle structure of the C type liquid cargo tank, a ship body outer plate can elastically deform due to the change of the ship stowage in the ship navigation process, and when the liquid cargo tank itself shrinks and deforms after low-temperature cargos are loaded on the liquid cargo tank, the pressure-bearing stow-wood and the partition plate can be separated; and the problem that the first epoxy resin layer is torn can beeffectively solved, it is
