It consists of the hanging material combined metal fitting 9 attached over the vertical material 2 of the H-shaped building frame 1 and the vertical material 2 of the lower-stage H-shaped building frame 1. The base end portion of the beam frame 6 and the free end portion of the diagonal member 8 are detachably connected to the upper and lower end portions, respectively, and the upper and lower end portions of the metal fitting 9 are vertically adjacent to the H-shaped building frames 1 and 1. Each vertical member 2 is attached and fixed by bolts 10 and nuts 11 inserted into the bolt insertion holes 5 of the respective vertical members 2. Since it is also used as a suspension material to connect the end, the number of members can be reduced and the production cost can be reduced. Rutotomoni can easily easily attached to the hanging member outer portion required height position load receiving stage S framework scaffold W by alternate fittings 9.

  Further, the hanging material combined metal fitting 9 is formed in a U-shaped cross section with a back plate portion 12 attached to the vertical member 2 of the H-shaped building frame 1 and both side plate portions 13, 13. Is fixed to the vertical member 2 of the H-shaped building frame 1 by bolts 10 and nuts 11, and the proximal-side vertical frame member 14 of the beam frame 6 is inserted into the upper ends of both side plate portions 13, 13. Then, it is fixed by bolts 15 and nuts 16 penetrating the base end side vertical frame member 14 from the both side plate portions 13, 13, and the free end portion of the diagonal member 8 is inserted into the lower end portions of the both side plate portions 13, 13. The bolts 15 and nuts 16 penetrating the diagonal member 8 from the side plate portions 13 and 13 are attached, and the structure is simple. Therefore, the manufacture is easy and inexpensive, and the H-shaped building frame 1 is provided. The mounting work of the hanging material combined metal fitting 9 and the beam frame 6 to the hanging material combined metal fitting 9 and For operation of mounting the diagonal members 8 is simple, it is possible to improve the construction efficiency.
