PROBLEM TO BE SOLVED: To prevent a ceiling joist from coming off from a clip by a simple configuration in the clip which connects the ceiling joist to a ceiling joist receiver.SOLUTION: A clip 1 is constituted of: an upper mounting part 11 mounted on an upper wall part 3a of a ceiling joist receiver 3; support pieces 12 bent at an approximately right angle with respect to the upper mounting part; and a pair of claw parts 13 each provided at the lower end of the support piece and locked to a lip part of the ceiling joist receiver 4. A tip part 11a of the upper mounting part mounted on the upper wall part is bent, the upper wall part is held between the support piece and the tip part, and a lockscrew 18 consisting of a tapping screw is made to penetrate through the support piece or the tip part and is screwed into a vertical wall part 3b of the ceiling joist receiver. Thus, not only looseness can be made hard to generate by a simple configuration, but also the clip can be easily mounted to the ceiling joist receiver, and fixing of the ceiling joist to the ceiling joist receiver without looseness can be achieved. |
