Ｌ３は２００００ｍｍである。[0006] A pair of frameworks includes a cantilevered upper column 1 having a predetermined spacing in the track direction, a lower column 2 composed of a rigid large truss that extends diagonally downward, an upper column 1 and a lower column 2. Are formed of H-section steel. The interval is, for example, 3000 for the upper part L1.

イントであり、剛接の大トラスとなる。As described above, since the configuration of the present invention is a cantilever column above the intersection, a bending moment is generated at the root of the cantilever column. Since this bending moment cannot be borne by the pin details, it is necessary to take rigid connection details. The intersections are rigid, and the truss column base is also rigidly connected to the pile. It is a rigid joint and becomes a rigid truss.

る。According to the present invention, the present invention has a slender shape by using an H-section steel and using a rigid frame structure and a rigid truss large truss structure in combination.
Since the area surrounded by the outline can be reduced and the shape is simple, the design cost and the manufacturing cost are reduced, the construction process is simplified, and it is more economical than conventional towers.
