PROBLEM TO BE SOLVED: To provide a membrane ceiling which can be retained by forming a part of the ceiling from an incombustible membrane material and introducing a proper tensile force to the incombustible membrane material.SOLUTION: A ceiling surface is constituted by spreading an incombustible membrane material 32. In that case, the ceiling surface is constructed by spreading the incombustible membrane material 32 while fixing a locking hook 31 to a mounting bracket 10 which is mounted along a spreading direction on a skeleton wall surface 3 in the vicinity of a ceiling surface 2, by using a membrane unit 30 including the incombustible membrane material 32, the locking hook 31 which is mounted along an extending direction of the mounting bracket 10 and capable of being locked along a length direction, and an elastic membrane material 33 interposed between the locking hook 31 and the incombustible membrane material 32. At such a time, the elastic membrane material 33 of the membrane unit 30 is housed within the mounting bracket 10. It is also preferable to close an opening of the mounting bracket 10 with a cap. |
