PROBLEM TO BE SOLVED: To provide a joint which can joint columns having dovetails together accurately and smoothly. SOLUTION: The joint consists of a pair of a first and a second pinching members 1-2 facing each other and a fastening bolt 3 fastening the pinching members 1-2, and joints two columns which are equipped with dovetails M-N in the longitudinal direction and intersect perpendicularly. Furthermore, the first pinching member 1 is constructed by a pinching plate 1A of barrel section, a hook 1B formed in an end section of the pinching plate 1A, and a bolt inserting hole 1C formed in the pinching plate 1A, moreover the second pinching member 2 is constructed by a pinching plate 2A of the barrel section, a supporting strip 2B formed in bend in an end section of the pinching plate 2A, a hook 2C formed in an end section of the supporting strip 2B, and a bolt inserting hole 2D formed in the pinching plate 2A. Additionally, the hooks 1B-2C of the pinching members 1-2 are hooked to a dovetail M edge of one side first column 5, respectively, and the other side second column 4 is pinched by the pinching plates 1A-2A of the pinching members 1-2, and then clamping bolts 3 are screwed into the bolt inserting holes 1C-2D, respectively.
