The utility model relates to the technical field of support structures for refractory brick masonry for a horizontal furnace. The support structure based on refractory brick masonry for a horizontal furnace has a first mounting groove opened in the middle of the top of the horizontal frame, and a first mounting plate is fixedly connected to the inside of the first mounting groove by bolts, and a jack is used instead of the previous wooden square stacking and wooden wedges to adjust the height and flatness, which significantly improves the support efficiency, saves manpower, and the arch formwork can be reused, which improves the assembly and disassembly efficiency, reduces material waste, and reduces costs.

[0004] However, it still has the following disadvantages in actual use:
