Is it okay for Sanhe Courtyard to overhang eaves without columns?

Whether the overhangs of the hospital can be column-free needs to be considered according to the specific situation.

Cantilever refers to the cantilever structure set on the overhanging edge of the building, which can effectively prevent rainwater from splashing into the house and increase the aesthetics of the building. In traditional quadrangle buildings, in order to ensure the structural safety and stability of overhangs, stone pillars are usually used as support and fixation.

However, if the structure of Sanheyuan is relatively simple, the overhanging span is not large, and there is not much load-bearing demand, you can consider not using columns as support. In this case, other light materials (such as wooden boards and steel structures) can be used instead of stone pillars, and corresponding reinforcement measures can be taken to ensure the structural safety of overhangs.
