Description of the Related Art Conventionally, in order to construct a framed temporary scaffolding using a building frame, the building frames arranged opposite to each other are connected by an X-shaped brace, and scaffolding boards are provided between the upper horizontal rails of both building frames. Erection of both building frames to make them stand-alone, which are continuously constructed in the lateral direction to build a first-floor floor, and then placed on scaffolding boards to add new building frames on each building frame, and the opposing building frames The second floor is constructed by combining with the braces and installing scaffolding boards.

に欠けるという問題がある。Further, in recent years, improvement of environmental beautification has become a major issue in urban areas and the like, and even a temporary scaffolding surrounding the outer periphery of a building is required to have a beautiful appearance. There is a problem in that the building frame has an unsightly design and lacks aesthetics because it has the appearance of connecting building frames with X-shaped braces.

The load concentrates on the connected part, and since the buckling strength is weak in this part, the strength of the temporary frame scaffolding is reduced.
