There is a certain type of intelligent ship, due to the appearance design requirements, there is a large linear aluminum ceiling outer plate in the superstructure area of the bow. There are difficulties in setting up scaffolding guardrails in the construction of sections, the welding construction of the berth, and the installation and construction of outfitting parts. That is to say, the existing scaffolding is made of steel pipe, and the outer panel of the aluminum ceiling has a large linear curvature, so the steel pipe scaffolding cannot be directly dropped to the surface of the outer panel of the ceiling to effectively bear the force. In view of the above problems, in order to reduce costs and increase efficiency, and improve the safety and economy of scaffolding guardrails, it is necessary to design and install a scaffold connection support on the surface of the outer plate of the aluminum hull ceiling to facilitate the erection of steel pipe scaffolding.

Existing technical problems: At present, there are mainly two methods for erecting temporary safety guardrails and operating platforms during hull construction.
