PROBLEM TO BE SOLVED: To easily construct a film ceiling on a ceiling surface of a wide area and to easily adjust a joint width even after construction.SOLUTION: This invention includes: a ceiling rail 12 where a bent part locking projection part 32 projected downwards is formed; a pair of film support members 11 for which a ceiling attaching plate part 21 and a distal end plate part 22 are bent at a bent part 24; and a push-up rail 13 and a push-up screw 14 for pushing up the ceiling attaching plate part 21 to the side of a ceiling substrate 2, and one end part and the other end part of a film material 3 are respectively put around a distal end edge of the distal end plate part 22 and attached to an outer side face 22a of the distal end plate part 22. Then, in the state of arranging the ceiling attaching plate part 21 of the pair of adjacent film support members 11 attached to the adjacently spread film material 3 between the ceiling rail 12 and the push-up rail 13, the push-up rail 13 is pushed up to the side of the ceiling substrate 2. Then, the film support members 11 are turned with the bent part 24 as a fulcrum, and the film material 3 is pulled and spread to the distal end plate part 22. |
