2. Description of the Prior Art The inventor of the present invention has devised a metal joint of a steel structure material which can be joined with one-touch, so that the joint can be made with a few welding spots and bolt tightening spots as much as possible. No. 4-62804).

FIGS. 11 to 13 show a joining method of a beam and a column using such a metal joint of a steel structure material. In the drawings, reference numeral 1 denotes a steel beam, 2 denotes a steel column, and a through hole through which a bolt penetrates. Bonding pieces 3 each having a joint piece 4 formed thereon and projecting at small intervals in a comb-teeth shape are provided on the end of the flange 1 a of the beam 1 and the side surface of the column 2, respectively.

The metal fittings 5 are installed on the beams 1 and the columns 2 at the factory side, and the beams 1 and the columns 2 are shipped and transported with the metal fittings 5 as shown in FIG.

At the site, as shown in FIG. 12, the beam 1 is hung by a crane between the pillars 2 previously built, and at this time, the joining pieces 3 of the joining hardware 5 are engaged with each other, as shown in FIG. Then, the beam 1 and the column 2 are joined to each other by joining the metal fittings 5 by inserting a high-strength bolt 6 into the through hole 4 and tightening with a nut.

In this manner, the metal joints 5 are interdigitated with the comb-shaped joint pieces 3 alternately positioned.
In addition, since this meshing is fastened in the orthogonal direction by the high-strength bolt 6, the comb-shaped joint piece 3 of each comb can transmit 90% or more of the axial force of the bolt by two-sided friction.

Further, since each joining piece 3 is subdivided as small as possible in the shape of a comb, the sectional axial strength of each joining piece 3 is smaller than the frictional force. That is, when the frictional force is given to each joint piece 3 by the high-strength bolt 6, its sectional proof strength is 100%.
Thus, the metal joints 5 are hardly separated from each other so that the two books are entangled with pages and combined.

In the illustrated example, the column 2 is described as a steel tube column having the inner diaphragm 7, but may be an H-shaped steel column. Also, the metal joint 5 is provided with a base 8 on which the joint pieces 3 are gathered, and the base 8 is welded to the beam 1 or the pillar 2. The base 8 may be a series, but as shown in FIG. The projecting portion 9 may be provided, and the projecting portion 9 may be arranged side by side.
