[0002] A cantilever structure is a structural form commonly seen in the construction industry, used to provide support when flapping and supporting larger spans. This structure is widely used in roof and gable designs. The cantilevered roof gives the building a unique appearance and expands the interior space without the need for pillars or other supporting structures.

[0003] The beam-type gable cantilever structure is used to support the bottom of the scaffolding, providing sufficient strength and stability. The cantilever bears the dynamic load generated during the construction. The beam-type cantilever structure is fixed by screws pre-buried in the gable. The screws directly bear the beam-type gable cantilever structure and the scaffolding structure assembled layer by layer at the upper end, resulting in a large pressure on the beam-type gable cantilever structure and insufficient use strength.
