れる。According to the conventional fence joint structure thus configured, the beam 9 is fixed to the side surface of the column 1 as follows. First, the hemispherical member 2 and the lower joint member 5 are applied to both side surfaces of the column 1 with the openings 2B and 5B aligned with each other. Next, the mounting bolt 8 is attached to the opening 5B of the joint member 3 and the opening 2B of the hemispherical member 2 via the washer 8A.
Then, the bolt 1 is passed through the bolt hole 1A of the column 1 and temporarily fixed. Next, the mounting angle of the beam 9 is determined, and the mounting bolt 8 is fully tightened. To adjust the mounting angle (θ 1 ) of the beam 9, the convex curved surface 2B of the hemispherical member 2 is adjusted to the concave curved surface 5A of the lower joint member 5.
Since it is spherically fitted inside, the adjustment can be done smoothly, and the adjustment range of the attachment angle (θ 1 ) can be widened to some extent because the openings 2B, 5B are formed larger than the diameter of the attachment bolt 8. In this way, when the lower joint member 5 of the joint member 3 is fixed to the column 1 through the hemispherical member 2 at a predetermined angular position, the end portion of the beam 9 is placed on the lower joint member 5, and the upper joint member 4 Over the lower joint member 5 and tighten the bolt 6. As a result, the beam 9 is fixed to the column 1.
