PURPOSE: To raise work efficiency by fitting a pair of pawl pieces rotatably within a supporting member, and fitting a sliding member in its upper portion to the pawl pieces and the supporting member, and housing a coil spring in the sliding member. CONSTITUTION: A ceiling suspension fitting comprises a pair of pawl pieces 1, 2, a supporting member 3, a sliding member 6, and a ceiling suspension screw rod 10. Pin inserting holes are made at an end portion, not its tip, of the pawl piece 1, and at a middle portion. Pins 4a, 4b are inserted in the pin insertion hole at the middle portion of the pawl pieces 1, 2 and a pin insertion hole at an end portion of the supporting member 3, so that the supporting member 3 is fitted rotatably. A pin insertion hole at an upper portion of the sliding member 6 is brought into contact with the pin insertion hole at the end portion of the pawl pieces 1, 2 and an oblong pin insertion hole 5 at a middle portion of the supporting member 3, then a pin 7 is inserted, so that the sliding member 6 is fitted slidably up and down. A deck plate, even when its corrugation pitch is somewhat changed, is dealt with by single type of fixture. |
