Description

  The present invention relates to a universal intersection fitting for holding a wire rope crossing portion of a wire rope binding facility of a rockfall countermeasure facility, and a wire rope binding work including the universal intersection fitting.

  As a rockfall countermeasure facility, a facility that suppresses the movement of floating stones that cause rockfalls by installing a wire rope or a wire mesh on topography such as a slope is known. In particular, a wire rope abutment is known in which wire ropes are installed on a slope or the like so as to cross in a lattice pattern and hold a floating stone or the like. In the wire rope working, a metal fitting for fixing two wire ropes to each other is used in order to hold (grip) an intersection of wire ropes (main rope, auxiliary rope). For example, a cross clip is disclosed in which two crossed wire ropes are sandwiched from above and below by a bent bar and a holding plate, and the holding plate is held by a bending prevention material and fastened by a nut. (For example, see Patent Document 1)

Japanese Patent No. 5388883

  However, the cross clip disclosed in Patent Document 1 is sandwiched from above and below by a bent bar and a holding plate at the intersection of two crossed wire ropes, and the holding plate is fixed to the bent bar by a holding nut. It is. For this reason, when the floating rope or the like held by the wire rope fence moves, if the wire rope is deformed, the holding force at the crossing portion of the wire rope may be reduced, and the crossing portion of the wire rope may be displaced. If the crossing part of a wire rope shift | deviates, the grid | lattice shape of a wire rope binding will have a part which spreads rather than the space | interval at the time of installation. Then, there existed a subject that a floating stone might drop | omit from the part which the space | interval of the grid | lattice-shaped space | interval of a wire rope construction spread.

  In addition, in wire rope working that has already been installed on slopes or the like, there is a case where it is necessary to reinforce the holding force at the intersection due to changes in the environment over time. For example, this may be the case when a huge float is generated on the slope after installing the wire rope fence. The cross clip disclosed in Patent Document 1 has a problem that it is difficult to add and attach to the crossing portion of the wire rope that is already fixed from the structure.

  The present invention solves the above-mentioned problem, and even if the wire rope is bent by an object held by the wire rope fence, the holding force of the intersection is difficult to decrease, and the existing wire rope fence is crossed. An object is to provide a universal intersection fitting and a wire rope binding that can be additionally attached.

  (I) A universal intersection metal fitting according to the present invention includes two structural members whose central portions are connected to each other so as to be rotatable. The structural members are located at both ends of the structural member, and a wire rope is fixed to the structural members. Two wire rope fixing portions and a connection portion connecting the two wire rope fixing portions, and the two structural members are overlapped in a direction intersecting each other, and the connection portions are coupled to each other. Yes.

  (Ii) The wire rope binding according to the present invention is a wire rope binding including a plurality of wire ropes crossed in a lattice shape, and a cross clip for fixing each crossing portion of the crossed wire ropes; A universal intersection fitting described in (i) above, wherein the universal intersection fitting covers the cross clip from above at the intersection and is fixed to the wire rope.

  With the configurations (i) and (ii) above, the universal intersection fitting and the wire rope binding work have the following effects. According to the universal intersection fitting and the wire rope work according to the present invention, one structural member is fixed to one of the two wire ropes at the intersection of the wire ropes, and the other structural member is attached to the other wire rope. Is fixed. And since two structural members are connected so that rotation is possible, even if the angle which a wire rope cross | intersects changes, a structural member tracks the angle and hold | maintains an intersection part. Therefore, even when a floating stone or the like moves on a slope or the like where the wire rope fence is installed, it is possible to suppress the interval between the intersections of the grid-like wire rope from expanding, and thus the effect of preventing falling rocks and the like Will increase.

  According to the universal intersection fitting and wire rope binding according to the present invention, the universal intersection fitting can be installed so as to cover the top of the cross clip provided at the intersection of the wire rope binding. Therefore, in addition to the effect that the cross clip holds the crossing portion, the universal intersection metal fitting also holds the crossing portion, so that the effect of holding the heavy rock such as the slope is enhanced.

  According to the universal intersection fitting according to the present invention, the universal intersection fitting can be additionally installed with respect to the existing wire rope binding. Therefore, it can install freely in the crossing part which wants to reinforce the existing wire rope construction, and the effect which prevents the falling rock etc. of the existing wire rope construction can be heightened.

Further, a part of the crossing portions 32 is fixed to anchors embedded in the ground by crossing anchor clips 70.

  FIG. 2 is a perspective view showing an example of the cross clip 20 of FIG. The cross clip 20 is configured by engaging a press plate 22 with a warped bolt 21. The holding plate material 22 is pressed against the wire rope 31 by a nut 26 screwed into the warped bolt 21.

  The warped bolt 21 is formed by bending one bar. One end of the warped bolt 21 is provided with a bolt part 27 into which a nut 26 is screwed. The other end of the warped bolt 21 is provided with an engaging portion 28 that engages the presser plate member 22 so as not to come out of the warped bolt 21. The warped bolt 21 has a bolt part 27 and an engaging part 28 located at both ends, and is formed in a substantially U shape. There is an arc 25 at the bottom of the U-shape. The warped bolt 21 is a part in the middle from the bolt part 27 and the engaging part 28 to the arc part 25, and is bent so that the arc part 25 approaches the bolt part 27 and the engaging part 28 side to form bent parts 23 and 24. doing. When viewed from the direction along the direction in which the wire rope 31 of FIG. 2 extends, the shape of the portion from the bolt portion 27 and the engaging portion 28 to the arc portion 25 through the bent portions 23 and 24 is formed in a substantially J shape. ing.

  In FIG. 2, the wire rope 30 is positioned on the wire rope 31 and an intersection 32 is formed. The wire rope 31 located on the lower side is supported by the bent portions 23 and 24 of the warped bolt 21 from the lower side. The wire rope 30 is overlaid on the wire rope 31 and further pressed by the arc portion 25 from above. Further, the wire rope 30 is pressed from above by the pressing plate material 22. That is, the wire rope 30 and the wire rope 31 are sandwiched between the bent portions 23 and 24 and the pressing plate material 22 and between the bent portions 23 and 24 and the arc portion 25. The holding plate member 22 is pressed by a nut 26 screwed into the bolt portion 27, and the nut 26 is tightened to press the wire rope 30 and the crossing portion 32 of the wire rope 31 from above and below. The intersecting portion 32 is pressed from above and below, and the wire rope 30 and the wire rope 31 are deformed to engage with each other. Further, the intersecting portion 32 is pressed from above and below, and a frictional force is generated at the contact portion between the wire rope 30 and the wire rope 31. Thereby, the intersection part 32 is hold | maintained so that it may not shift | deviate from the state installed initially.

  In addition, it is an example of the cross clip 20 shown by FIG. 2, and is not limited only to this form. As long as the crossing part 32 of the wire rope 30 and the wire rope 31 is hold | maintained, you may use the cross clip 20 of another form.

(Free intersection bracket 10)
FIG. 3 is an enlarged view of a portion A in FIG. FIG. 3 is an enlarged view of the intersection 32 where the universal intersection fitting 10 is installed. In the first embodiment, the universal intersection metal fitting 10 is installed at the intersection 32 where the cross clip 20 is provided. However, you may install in the crossing part 32 in which the cross clip 20 is not installed. In this case, the intersection 32 of the wire ropes 30 and 31 is held only by the universal intersection fitting 10. Depending on the load applied to the wire rope binding 100, only the universal intersection fitting 10 may be installed at the intersection 32.

  The universal intersection metal fitting 10 is configured by overlapping a structural member 11 a and a structural member 11 b and connecting them with a connecting member 12. In the first embodiment, the structural member 11a and the structural member 11b have the same shape. The structural member 11a and the structural member 11b are connected to each other so as to be rotatable in a horizontal direction (a direction parallel to a surface on which the wire rope binding 100 is installed). In the first embodiment, the connecting member 12 includes a bolt 61 and two nuts 62. The two nuts 62 are passed through the structural member 11a and the structural member 11b through the bolt 61 and then fixed to the screwed portion of the bolt 61 by a double nut so that the structural members 11a and 11b cannot be removed from the bolt 61. And the nut 62 is being fixed to the screwing part of the volt | bolt 61 so that an appropriate clearance may be provided between the structural member 11a and the structural member 11b. Since the connecting member 12 is configured as described above, the structural member 11a and the structural member 11b are rotatable with respect to each other.

  The wire rope 30 is fixed to the wire rope fixing part 13a and the wire rope fixing part 13b of the structural member 11a. In the first embodiment, the U-shaped bolt 65a is passed through the hole 17 provided in the wire rope fixing portion 13a at one end of the structural member 11a, and the wire rope 30 is connected to the arc portion 66a of the U-shaped bolt 65a. It is sandwiched and fixed between the back surface 14a of the wire rope fixing portion 13a. The screwed portions formed at both ends of the U-shaped bolt 65a are passed through two holes 17 formed in the wire rope fixing portion 13a. The nuts 63 are respectively screwed into screwed portions formed at both ends of the U-shaped bolt 65a, and the screwed nuts 63 are brought into contact with the surface of the wire rope fixing portion 13a and fastened with a predetermined torque. Similarly, at the other end portion of the structural member 11a, the wire rope 30 is sandwiched and fixed by the U-shaped bolt 65b and the wire rope fixing portion 13b.

  The wire rope 31 is sandwiched and fixed by a wire rope fixing part 13c and a U-bolt 65c at one end of the structural member 11b. The wire rope 31 is sandwiched and fixed by a wire rope fixing part 13d and a U-shaped bolt 65d at the other end of the structural member 11b. The structure in which the wire rope 31 is fixed to the structural member 11b is the same as the structure in which the wire rope 30 is fixed to the structural member 11a.

  FIG. 4 is an explanatory view of the structure of the universal intersection fitting 10 of FIG. FIG. 4A is a view of the universal intersection fitting 10 as seen from the back side, that is, from the crossing portion 32 side between the wire rope 30 and the wire rope 31. FIG. 4B is a top view of FIG. FIG. 4C is a side view of FIG. FIG. 5 is an explanatory view of the structural member 11 constituting the universal intersection fitting 10 of FIG. 4 shows a structure in a state where the universal intersection fitting 10 shown in FIG. 4 is installed at the intersection 32 of the wire rope binding 100, the wire rope 30, the wire rope 31, and the cross clip 20 are omitted. ing.

  The structural member 11a and the structural member 11b are formed by bending a strip-shaped sheet metal. Hereinafter, the structural member 11a and the structural member 11b are collectively referred to as the structural member 11. In the following description, when the subscripts (a, b, etc.) of the reference numerals shown in the drawings are omitted, the parts with the subscripts are collectively named. In the first embodiment, the structural member 11 is formed by bending a rectangular sheet metal, but may be a sheet metal of another shape. The structural member 11 has wire rope fixing portions 13 at both ends. The two wire rope fixing portions 13 are arranged on substantially the same plane. The back surface 14 of the wire rope fixing portion 13 is a flat surface, and the wire ropes 30 and 31 are in contact with this surface. The wire ropes 30 and 31 are sandwiched and fixed between the wire rope fixing portion 13 and the U-shaped bolt 65 passed through the hole 17 provided in the wire rope fixing portion 13. That is, the wire ropes 30 and 31 are in contact with the wire rope fixing part 13 and the U-shaped bolt 65, and the universal intersection fitting 10 is fixed to the wire ropes 30 and 31 by the frictional force caused by the contact. The wire rope fixing part 13 and the wire ropes 30 and 31 are fixed using U-shaped bolts 65, but any other structure can be used as long as the wire rope is pressed against and contacted with the wire rope fixing part 13. Means may be used. For example, the structural member 11 is attached to the wire ropes 30 and 31 by making another flat member and the back surface 14 of the wire rope fixing part 13 face each other, sandwiching the wire ropes 30 and 31 therebetween, and tightening them with bolts and nuts. It may be fixed.

  In addition, the wire rope fixing part 13 and the wire ropes 30 and 31 may be fixed at a plurality of locations in one wire rope fixing part 13. For example, in the universal intersection fitting 10 according to Embodiment 1, the wire rope fixing portion 13 may be enlarged so that two U-bolts 65 can be installed. By comprising in this way, the frictional force between the wire rope fixing | fixed part 13 and the wire ropes 30 and 31 can be raised, and the wire rope fixing | fixed part 13 hold | maintains so that it may not shift | deviate with respect to the wire ropes 30 and 31. The power can be improved.

  The structural member 11 has a connecting portion 15 between wire rope fixing portions 13 at both ends. The connecting portion 15 and the wire rope fixing portion 13 are connected by a separating portion 19 that extends upward. The connecting portion 15 is substantially parallel to the two wire rope fixing portions 13. A hole 18 is formed in the connection portion 15. The two structural members 11a and 11b are connected by overlapping the connecting portion 15a and the connecting portion 15b. The bolts 61 constituting the connecting member 12 are passed through the holes 18 formed in the connecting portions 15 of the two structural members 11a and 11b. Two nuts 62 are passed through the threaded portion of the bolt 61 passed through the hole 18 and are fixed in place by a double nut. The two structural members 11a and 11b are connected with a gap between the connecting portions 15. The nut 62 is fixed so that a gap is formed between the two connecting portions 15. In the first embodiment, when connecting the connecting portions 15 of the two structural members 11a and 11b, the bolts 61 and the nuts 62 are connected, but the two structural members 11a and 11b are connected. Can be rotated relatively in a plane parallel to the connecting portion 15, and even if a load is applied to the connecting member 12, the two structural members 11 a and 11 b do not come off and other means can be used. Good. For example, the rod-shaped member may be passed through the hole 18, the retaining member is fixed to the rod-shaped member, and the two structural members 11a and 11b may be relatively rotatably connected. Since the connecting member 12 is constituted by the bolt 61 and the nut 62, there is an advantage that the assembling work becomes easy.

(Function of the universal intersection bracket 10)
As shown in FIG. 1, the universal intersection fitting 10 is installed at the intersection 32 of the wire ropes 30 and 31 of the wire rope binding 100 installed on a slope such as a cliff. For example, a load of a floating stone 50 on a slope is applied to each of the wire ropes 30 and 31 of the wire rope working 100. When a load is applied to the wire ropes 30 and 31, the wire ropes 30 and 31 bend according to the load. When the wire ropes 30 and 31 are bent, the wire rope 30 and the wire rope 31 try to move so as to be relatively displaced at the intersection 32. Then, the crossing portion 32 of the wire rope roofing 100 is displaced from the initial position. When the crossing portions 32 are shifted, the distance between the crossing portions 32 of the wire rope roofing 100 changes. Then, the wire rope binding 100 that has been stretched in a lattice shape is deformed in the lattice shape, so that a portion having a wide lattice interval and a narrow portion can be formed. If there is a place where the grid shape interval of the wire rope fence 100 is wide, floating stones or the like may fall off from the wire rope fence 100, and there may be a place where the load is concentrated on the local part of the wire rope fence 100. There is a case. In order not to be in such a state, it is necessary to hold each crossing portion 32 of the wire rope working 100 so that it does not shift even when a load is applied.

  FIG. 6 is a view showing a state in which the structural member 11a and the structural member 11b of FIG. 4A are relatively rotated. In the structural member 11 shown in FIG. 6, the dimension of the connecting portion 15 in the direction from one wire rope fixing portion 13 to the other wire rope fixing portion 13 is a length dimension L. A dimension in a direction orthogonal to the length dimension L is a width dimension W. The connecting portion 15 of the structural member 11 has a length dimension L larger than a width dimension W. With this configuration, the structural member 11a and the structural member 11b can be connected to each other by overlapping the connection portions 15 so as to intersect each other. Further, by setting the width dimension W and the length dimension L, the structural member 11a can be rotated with respect to the structural member 11b as shown in FIG. The rotatable range is until the connecting portion 15 of the structural member 11a comes into contact with the separation portion 19 of the structural member 11b.

  For example, when a load is applied in the direction intersecting the direction in which the wire rope 30 extends (the direction along the direction in which the wire rope 31 extends), that is, when the load F is applied in the direction of the arrow shown in FIG. The rope 30 bends so as to be inclined with respect to the wire rope 31. The load F is applied so that the structural member 11a to which the wire rope 30 is fixed is moved downward in FIG. Then, the load F applied to the structural member 11a is applied so as to move the structural member 11b from the structural member 11a through the bolt 61 of the connecting member 12 in the downward direction in FIG. However, the universal intersection fitting 10 holds the positions of the intersecting portions 32 of the wire rope 30 and the wire rope 31 at four locations of the wire rope fixing portions 13a to 13d. Therefore, in the wire rope fixing portions 13 a and 13 b, the position of the intersection portion 32 is determined by the frictional force generated by the force compressing the wire rope 30 by the wire rope fixing portion 13 and the U-shaped bolt 65 and the shear strength of the U-shaped bolt 65. Is retained. Further, in the wire rope fixing portions 13c and 13d, the intersecting portion 32 is held by the frictional force generated by the force compressing the wire rope 30 by the wire rope fixing portion 13 and the U-shaped bolt 65. With this configuration, the universal intersection fitting 10 can firmly hold the position of the intersecting portion 32. As a result, since the shift | offset | difference of the wire rope 30 and the wire rope 31 can be suppressed, the lattice shape of the wire rope binding 100 can be hold | maintained.

  As shown in FIG. 6, the universal intersection metal fitting 10 can be attached to the intersection 32 even when the structural member 11 a and the structural member 11 b are relatively rotated. For this reason, in the case where the wire rope work 100 is installed on the terrain having a complicated undulation, even if the wire ropes 30 and 31 are bent along the undulation, the universal intersection fitting 10 is a wire rope. The intersecting portion 32 can be held in a state of following 30 and 31. Therefore, since the universal intersection metal fitting 10 does not excessively restrain the intersection portion 32, the wire ropes 30 and 31 do not receive a load locally. Therefore, even if it is a case where it installs on the topography which has a complicated undulation, the wire rope staking 100 can maintain the intensity | strength and durability which were intended.

  The universal intersection fitting 10 is installed so as to cover the intersecting portion 32, and the four wire rope fixing portions 13 are disposed so as to surround the intersecting portion 32. Therefore, the universal intersection metal fitting 10 can be installed by adding a part for holding the intersection 32 such as the cross clip 20 to the installed intersection 32. Thereby, intensity | strength can be improved further with respect to the conventional wire rope binding. In addition, when installing the universal intersection metal fitting 10 in the crossing part 32 in which the cross clip 20 is not installed, the length of the separation part 19 (height dimension H shown in FIG. 5) can be set to an arbitrary dimension. . Since the cross clip 20 is not installed inside as shown in FIG. 3, the universal intersection fitting 10 installed at the intersection 32 where the cross clip 20 is not installed is the four wire ropes of the universal intersection fitting 10. It is not necessary to provide a space in the region surrounded by the fixed portion 13. For example, the structural member 11 constituting the universal intersection fitting 10 may be a flat plate having wire rope fixing portions 13 at both ends.

(Effect of Embodiment 1)
(1) The universal intersection metal fitting 10 according to Embodiment 1 includes two structural members 11a and 11b whose central portions are connected to each other so as to be rotatable. The structural member 11 is located at both ends of the structural member 11, the two wire rope fixing portions 13 to which the wire ropes 30 and 31 are fixed, and the connection portion 15 that connects between the two wire rope fixing portions 13. . The two structural members 11 are overlapped in a direction intersecting each other, and the connection portions 15 are connected to each other.
By being configured in this way, even if the angle at which the wire ropes 30 and 31 of the wire rope working 100 cross each other changes, the structural member 11 follows the angle and holds the intersecting portion 32. Therefore, even when the floating stone 50 moves on the slope or the like where the wire rope fence 100 is installed, it is possible to suppress an increase in the interval between the intersecting portions 32 of the lattice-like wire ropes 30 and 31, so that a falling rock The effect which prevents etc. increases.

(2) According to the universal intersection fitting 10 according to the first embodiment, the connection portion 15 is located away from the virtual plane passing through the two wire rope fixing portions 13.
By being configured in this way, the universal intersection fitting 10 can be installed so as to cover the cross clip 20 provided at the crossing portion 32 of the wire rope binding 100. Therefore, in addition to the effect that the cross clip 20 holds the intersecting portion 32, the universal intersection fitting 10 also holds the intersecting portion 32, so that the effect of holding the heavy floating stone 50 such as a slope is enhanced.

(3) According to the universal intersection fitting 10 according to the first embodiment, the rotation axis around which the two structural members 11 rotate intersects the virtual plane including the two wire rope fixing portions 13 substantially perpendicularly.

It is set to be larger than the width dimension which is a dimension in the direction orthogonal to the thickness dimension.
By being configured in this way, the universal intersection fitting 10 can be configured by stacking two structural members 11 formed by bending a belt-shaped sheet metal. And since the two structural member 11 piled up can mutually rotate, the universal intersection metal fitting 10 can acquire the effect described in said (1)-(4).

(6) According to the universal intersection fitting 10 according to the first embodiment, the U-shaped bolt 65 attached to the wire rope fixing portion 13 is provided. The U-shaped bolt 65 and the wire rope fixing portion 13 are fixed with the wire ropes 30 and 31 interposed therebetween.
By being configured in this way, the universal intersection fitting 10 is firmly fixed to the wire ropes 30 and 31.

The universal intersection metal fitting 10 covers the cross clip 20 from above at the intersection 32 and is fixed to the wire ropes 30 and 31.
By being configured in this manner, the wire rope work 100 improves the force to hold the position of the crossing portion 32 of the wire ropes 30 and 31, and thus suppresses the floating stone 50 and the like in a complicated terrain such as a slope. Can do.

Embodiment 2. FIG.
The universal intersection fitting 210 according to the second embodiment is obtained by changing the shape of the structural member 211 with respect to the universal intersection fitting 10 of the first embodiment. In the second embodiment, description will be made centering on changes from the first embodiment.

  FIG. 7 is a side view of the universal intersection fitting 210 according to Embodiment 2 of the present invention. FIG. 8 is an explanatory diagram of the structural member 211 of FIG. In the universal intersection fitting 210 according to the second embodiment, the separating portion 219 of the structural member 211 is inclined. In other words, in the two spaced apart portions 219 of the structural member 211, the distance between the end portions on the wire rope fixing portion 13 side is set larger than the distance between the end portions on the connecting portion 15 side. Therefore, in the structural member 211, the distance between the wire rope fixing portions 13 is longer than that of the structural member 11 according to the first embodiment. With this structure, the wire ropes 30 and 31 around the intersection 32 can be reinforced by the structural member 211 having high rigidity, but a longer section can be reinforced than in the first embodiment. In addition, since the structural member 211 according to the second embodiment is longer than the structural member 11 according to the first embodiment, it is visually recognized at what angle the wire rope 30 and the wire rope 31 intersect at the intersection 32. The effect that it is easy is acquired. That is, the universal intersection fitting 210 is easy to visually check whether the wire ropes 30 and 31 are following a slope having a complicated shape while holding the intersecting portion 32, so that it is easy to confirm whether the wire ropes 30 and 31 are properly installed. .

  In Embodiment 1 and Embodiment 2, the universal intersection metal fittings 10 and 210 are configured by combining two structural members 11 or 211 having the same shape. However, you may comprise combining the structural member of a different shape. For example, you may comprise a universal intersection metal fitting combining the structural member 11 of Embodiment 1, and the structural member 211 of Embodiment 2. FIG. In addition, for example, the free intersection metal fitting may be configured by combining the structural members 11 and 211 having different heights H of the separation portion 19. By configuring in this way, when adding the universal intersection fittings 10 and 210 to the already installed wire rope working 100, the structural members are adapted to the wire ropes 30 and 31 stretched along the complicated terrain. 11, 211 can be attached.

(8) According to the universal intersection fitting 210 according to the second embodiment, the separating portion 19 that connects the wire rope fixing portion 13 and the connecting portion 15 is inclined from the wire rope fixing portion 13 toward the connecting portion 15. ing.
With this configuration, the universal intersection fitting 210 can easily recognize the angle of the intersecting portion 32 due to the bending of the wire ropes 30 and 31 while holding the intersecting portion 32.
