本発明の接合金物のの一例を示す図である。In a split T having the same thickness of the T-flange, a bolt reaction force is generated by the bolt. Therefore, if the thickness of the T-flange is not excessively increased, the joint efficiency becomes about 60% of the bolt strength. I could only expect. So T
By making the high-split T thick such that the flange thickness increases from the flange tip to the T web,
The joint efficiency was able to be increased to about 90% of the bolt strength. However, the number of bolts is restricted by the arrangement of the tension bolts, and it is difficult to apply to a large tensile force. FIG. 2 is a diagram showing that even when the high split T is used, since the tension bolts are located at the upper and lower ends, a cavity tends to be formed in the portion C when a tensile force is applied. Therefore, a tension bolt is provided on the central axis of the T web to provide a metal joint whose bolt strength contributes to 100% joint efficiency. Figures 5-10
