The structure is such that a steel material having a thickness corresponding to the proof stress of the hanging bolt is hung on the upper end of the hanging bolt and the field bridge, and is welded and fixed to each.

[Problems to be solved by the invention] Since welding is used in the conventional structure of the base line brace of the ceiling, the length and the inclination angle are set according to the standard spacing of the field bridge and the height of the ceiling rim. However, it was easy to form the truss, but in addition to the assembly structure of the entire ceiling substrate, another type of welding process was added, and measures were desired from the viewpoint of using fire and preventing electric shock accidents. .

Therefore, the applicant of the present invention first devised a locking metal used for the upper end of the hanging bolt and a base brace (Practical application No. 1-29595: No. 2-121503). "Connector for insert"), as shown in FIG. 1, avoiding the welding work especially in the upper part of the ceiling rim, and enabling screwing from below,
I proposed a bifurcated brave hardware.

[Means for Solving the Problem] However, in the bracing hardware proposed above, welding is still used to secure the lower end of the bracing to the field bridge, and it is necessary to securely secure the brazing at two locations. It was

The present invention was invented in the development process of improving the workability and ensuring safety when constructing a ceiling base structure based on the above-mentioned proposal, and in particular, the bottom end of the brace and the field connection The gist is that the welding work is completely abolished by using the metal fittings also at the fixing portion.
