  By the way, in order to tension the sheet-like member in the surrounding area in a good manner, it is necessary to apply an equal tension to the sheet-like member. That is, when fixing the sheet-like member to the frame, it is necessary to pull the sheet-like member evenly.

  However, with the above-described fixing method, it is difficult to fix the sheet-like member to the frame while applying an equal tension. That is, when a sheet-like member is affixed to the frame, it takes time for the sheet-like member to be fixed to the frame due to the influence of the curing time of the adhesive, so that the sheet-like member cannot maintain a tension state. May end up. Further, when fixing the sheet-like member by fitting the presser member into the groove of the frame, it is necessary to sequentially fit the long presser member into the groove. It is difficult to apply an equal tension to. In particular, the longer the sheet-like member is, the more difficult it is to fix it while applying an even tension to the sheet member.

  For example, until now, flame barriers installed in large buildings such as large stores have been made of glass, but there is a risk of cracking and falling when an earthquake occurs. It is being replaced. In this case, since the sheet-like member is arranged along the ceiling of the building, it becomes very long. Therefore, when a sheet-like member is adopted as a flameproof hanging wall, it is difficult to perform construction while applying tension, and a laborious operation is required.

  Then, in view of such a situation, this invention makes it a subject to provide the flame | frame metal fittings, flame | frame, and smoke-proof hanging wall which can make a uniform tension | tensile_strength act on a sheet-like member by simple operation | work.
