Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wire rope crossing fastener used for fastening the crossing of wire ropes stretched vertically and horizontally in a small suspension bridge or the like.

[0002]

[Prior art]

 Fig. 5 shows a conventional cross-section fastener used for rockfall prevention nets, etc. This fastener has a pair of U bolts 2 and 2 provided on the plate 1 and has a circular arc section on the plate surface of the plate 1. Is formed with the guide groove 3.

Then, one wire rope a is put along the guide groove 3 and the other wire rope b is passed through the inside of the U bolts 2 and 2 to intersect with the one wire rope a. 2, 2 are tightened by nuts 4, 4 respectively, and the tightening force is used to tighten the intersection of the wire ropes a, b.

[0004]

[Problems to be solved by the device]

 However, in such a conventional fastener, one wire rope a simply contacts the guide groove 3 of the plate 1, and the other wire rope b almost linearly contacts the U bolts 2 and 2. Therefore, the fastening force is weak, and the wire ropes a and b are easily displaced. Therefore, it is difficult to use the wire ropes at the intersections of wire ropes in a suspension bridge or the like where a strong fastening force is required.

Further, since the U-bolt 2 only penetrates the single plate 1, when the U-bolt 2 is tightened via the nut 4, the U-bolt 2 sways and therefore the tightening thereof is performed. Workability deteriorates and work efficiency decreases.

The present invention has been made paying attention to such a point, and the purpose thereof is to obtain a strong fastening force, and to sufficiently apply it to a wire rope intersection in a suspension bridge or the like. An object of the present invention is to provide a wire rope crossing portion fastening member that is capable of performing the tightening work easily and efficiently.

[0007]

[Means for Solving the Problems]

 In order to achieve such an object, the present invention has an upper plate and a lower plate, which are arranged so as to face each other, in a wire rope intersection fastening fitting that fastens the intersection of a pair of wire ropes stretched vertically and horizontally. A guide groove formed in the lower surface of the upper plate and extending in one direction from the one edge to the other edge, the guide groove having an arcuate cross section, and formed in the upper surface of the lower plate from the one edge to the other edge. And a guide groove having an arcuate cross section extending in a direction intersecting with the guide groove, streak-shaped irregularities formed on the inner surface of each guide groove, and a portion where each guide groove is formed on the upper plate. Through holes for bolt insertion formed in at least four uniform parts, screw holes for bolt engagement formed in the lower plate facing the above through holes, and through holes for the above. Communication And a bolt screwed into the screw hole, one wire rope is fitted in the guide groove of the upper plate, and the other wire rope is fitted in the guide groove of the lower plate. By intersecting the wire ropes and tightening the bolts in this state, the intersections of the wire ropes are sandwiched and fastened by the upper plate and the lower plate.

[0008]

[Action]

 When fastening the intersection of the wire ropes arranged vertically and horizontally, first pass the wire rope between the upper plate and the lower plate, align one wire rope with the guide groove of the upper plate, and the other wire rope. Align with the guide groove of the lower plate, and tighten the bolts evenly in this state.

By this tightening, the wire rope is strongly sandwiched between the upper plate and the lower plate, the peripheral surface of one wire rope is crimped to the inner surface of the guide groove of the upper plate, and the peripheral surface of the other wire rope is It is crimped to the inner surface of the guide groove of the lower plate, but here, the inner surface of each of the above-mentioned guide grooves is formed with streaky unevenness, so that between the peripheral surface of the wire rope and each guide groove. A strong frictional force is generated in each case, so that the wire rope does not move relative to the fastening tool, and a stable and strong fastening state is obtained.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS.

Reference numeral 11 shown in the drawing is an upper plate, 12 is a lower plate, and the upper plate 11 and the lower plate 12 are arranged to face each other. The upper plate 11 and the lower plate 12 are each made of a metal such as FCD450. As shown in FIG. 3, a guide groove 13 having an arcuate cross section is formed on the lower surface of the upper plate 11 from the middle portion of one end edge to the middle portion of the other end edge.

Further, as shown in FIG. 4, on the lower surface of the lower plate 12, there is formed a guide groove 14 having an arcuate cross section extending in a direction intersecting with the guide groove 13 in the upper plate 11 from the middle portion of one end to the other end. It is formed over the middle part of the edge. The inner surface of each of the guide grooves 13 and 14 is provided with streak-shaped irregularities 15 and 16 which are inclined with respect to the longitudinal direction of the guide grooves 13 and 14, respectively.

Through holes 17 for inserting bolts are formed in four portions of the upper plate 11, which are evenly spaced from each other where the guide grooves 13 and 14 are formed. Further, on the lower plate 12, screw holes 18 for screwing bolts are formed facing the through holes 17 ... Bolts 19 are screwed into the screw holes 18 of the lower plate 12 through the through holes 17 from the upper surface of the upper plate 11. In addition, a mark 20 such as a trademark of the manufacturer of this fastener is provided on the center of the surface of the upper plate 11.

The procedure of fastening the intersecting portions of the wire ropes a and b arranged vertically and horizontally by using the fastener thus configured will be described first. First, the wire rope a and the wire rope a and b between the upper plate 11 and the lower plate 12 will be described. b, one wire rope a is guided along the guide groove 13 of the upper plate 11, the other wire rope b is guided along the guide groove 14 of the lower plate 12, and in this state, the bolts 19 are evenly distributed. tighten.

By this tightening, the wire ropes a and b are strongly sandwiched between the upper plate 11 and the lower plate 12, and the peripheral surface of one wire rope a is crimped to the inner surface of the guide groove 13 of the upper plate 11, The peripheral surface of the other wire rope b is crimped to the inner surface of the guide groove 14 of the lower plate 12.

Here, streak-shaped irregularities 15 and 16 are formed on the inner surfaces of the guide grooves 13 and 14, respectively. Therefore, between the peripheral surface of the wire rope a and the guide groove 13 of the upper plate 11. , And a strong frictional force is generated between the peripheral surface of the wire rope b and the guide groove 14 of the lower plate 12, so that the wire ropes a and b do not move relative to the fastening metal fittings and are stable. A strong fastening condition can be obtained.

Therefore, it can be effectively applied to, for example, fastening a crossing portion between a balustrade (wire rope balustrade) and a suspension rope (hanger rope) in a small-scale suspension bridge where a strong fastening force is required. Since the fastener 20 is provided with the manufacturer's mark 20 on the surface of the upper plate 11, it is possible to recognize the construction source of the suspension bridge and expect an effective advertising effect.

On the other hand, at the time of fastening work, the bolts 19 ... Are in a stable state in which they are screwed into the screw holes 18 formed in the lower plate 12. Therefore, when tightening these bolts 19 ... Since the bolts 19 do not swing, the tightening work can be performed easily and efficiently, and the workability is improved.

The fastening fitting of the present invention can be used not only for a small-scale suspension bridge, but also for fastening a wire rope intersection at another structural facility or the like.

[0020]

[Effect of device]

 As described above, according to this invention, a strong fastening force can be obtained, it can be effectively applied to the intersection of wire ropes in suspension bridges, etc., and the tightening work can be done easily and efficiently. There is an advantage that workability is improved.
