Embodiment Construction

[0054] In the following, the method of connecting aluminum square tubes to each other will be described with reference to the accompanying drawings, assuming that the metal block of the original joint is formed of aluminum, but the present invention is not limited thereto.

[0055] Example 1 (Invention A)

[0056] figure 1 and figure 2 Front view and rear view, respectively, which show the state in which square tubes are connected to each other by means of bolt-nut connections using front T-joints and connection plates with planes close to isosceles triangles according to the present invention .

[0057] Steel nuts 3 are respectively installed and fixed in the tee connecting arms 1-1, 1-2, 1-3 of the front T-shaped aluminum joint 1, so that the threaded hole 2 runs through from the front to the rear. Reference numeral 4 designates a cavity, which reaches from the front to the rear, for reducing the weight of the joint 1 . And, on one side of the square pipes 5-1, 5-2, 5-3...
