ABSTRACT:
A joint structure has a male-side metal joint (3) fixed on a column (1) and a female-side metal joint (4) fixed on a beam (2). The two metal joint (3, 4) are common joints having the same shape, and have a first contacting surface (81), a second contacting surface (82) which continues from the back thereof and curves upward at an angle of less than 90.degree., and a third contacting surface (83) which continues from the front of the first contacting surface and curves downward at an angle of 270.degree. or more. When one of the two metal joints (3, 4) is put on the other, these contacting surfaces contact intimately with each other. If the two joints are fastened by a fastening bolt (5) in this state, the beam (2) is jointed to the column (1). Because the first to third contacting surfaces (81 to 83) incline, the joint metals (3, 4) do not get out of place longitudinally or vertically. Hence the simple subsequent operation of fastening and so forth can be carried out easily.
