[0002]

2. 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.

In this way, by constructing the frame temporary scaffolding of a desired height by sequentially assembling each floor upward, the scaffolding is disassembled from the upper floor in reverse order. To go.

By the way, since the conventional brace has a structure in which two pipes are connected to each other in an X shape, only the opposing construction frames are connected to each other, and the scaffolding plate is assembled after the floor is assembled. Although it will have the function of forming safety fences on both sides of the floor, when assembling the upper floor, the opposite building frames are connected after the building is built, so the scaffolding board of the scaffolding board can be used when assembling the upper floor. Since there is no such thing as a handrail to ensure safety on both sides, there is a problem that the risk of work increases as the scaffolding assembly becomes expensive. The same applies when dismantling.

[0005]

[Problems to be Solved by the Invention] Therefore, when constructing a temporary frame scaffold, it is considered to attach the handrail frame to the upper part between the building frames by using the clamp metal fittings. Since it takes time and labor, and both ends of the handrail frame cannot be temporarily placed between the building frames, there is a problem that a plurality of workers are required to attach and detach.
