2. Description of the Related Art A suspension bridge which is a typical example of a suspension structure is shown in FIG. As is well known, a pair of left and right main cables 3 are respectively extended between the tops of a pair of main towers 2 erected on a base 1 realized by an abutment, and both ends of the suspension bridge are anchorages 5. To the main tower 2
And a horizontal girder 4 horizontally arranged between the lower portions of the main cable 3 is suspended and supported by a suspension cable 6 suspended from the pair of left and right main cables 3. By reinforcing the upper structure with the main cable 3, Since the number of piers is reduced and the design load is shared by the main cable 3, the cross-sectional shape of the horizontal girder 4 can be reduced. For this reason, it has a feature that the concentrated load can be dispersed and alleviated by the arbitrary deformation of the main cable 3 and supported.

In the above-mentioned suspension structure, a cable connection fitting is used at a place where the suspension cable 6 is connected to the main cable 3. FIG. 4 shows an example of a conventional cable connecting fitting. The cable connecting fitting 21 is composed of a pair of saddle-shaped fitting pieces 22 and is sandwiched between the peripheral surfaces of the main cable 3 in a palm-shape manner. Attached by tightening the attaching bolt 14 and the suspension cable 6
The main cable 3 and the suspension cable 6 are connected by fixing a stopper 16 serving as an upper end fixing portion to a set of metal pieces 22 via pin bolts 15.

By the way, as shown in FIG. 4A, the mounting position of the pin bolt 15 on the metal fitting piece 22 is farther from the holding main cable 3 than the mounting position of the lug bolt 14. And the distance from the suspension fulcrum 20 when the metal piece 22 is suspended is large. For example, when the diameter of the main cable 3 made of a strand rope is φ40 mm, a steel fitting piece 22 having a thickness of 12 mm, a length (length in a direction orthogonal to the main cable 3) of 240 mm, and a width of 150 mm is used. Thus, the eccentricity e 0 of the mounting position of the pin bolt 15 with respect to the main cable 3 is as large as 135 mm.

[0005] When the horizontal girder 4 is hung and supported via the hanging cable 6 by using such a cable connecting metal fitting 21, as shown in FIG. If the piece 22 is inclined by the angle θ, the torsional load P at that time becomes the torsional moment T r0 given to the main cable 3 = P × e 0 (135) × cos θ. Since e 0 is large, the torsional moment T r0 is Naturally, the size of the main cable 3 is increased, and as a result, the main cable 3 is apt to be torsionally deformed.

Embodiments of the present invention will be described below with reference to FIGS. For example, when the diameter of the main cable 3 made of a strand rope is φ40 mm, a steel fitting piece 9 having a thickness of 12 mm, a length (length in a direction orthogonal to the main cable 3) of 150 mm, and a width of 150 mm is used. Thus, the eccentricity e 1 of the mounting position of the pin bolt 15 with respect to the main cable 3 is as extremely small as 45 mm. As shown in FIG. 3B, assuming that the bracket piece 9 is inclined at an angle θ with respect to the vertical direction of the hanging load P, the torsional moment Tr 1 = P × given by the hanging load P to the main cable 3 at that time. 45 × cos θ, and since e 1 is small, the torsional moment Tr 1 naturally becomes small.
Since it is 1/3 of the conventional one shown in (b), torsional deformation is unlikely to occur, and the strength of the main cable 3 against the load is not reduced. In addition, the outer shape and the weight are reduced to 60% as compared with the conventional fitting.
